                                 Old Changelog

Changes done to curl and libcurl from 1997 to 2010, edited manually. The most
recent changes are always generated into the CHANGES file straight from git.

Kamil Dudka (17 June 2010)
- Improve test575 in order to not fail with threaded DNS resolver.

Version 7.21.0 (16 June 2010)

Daniel Stenberg (5 June 2010)
- Constantine Sapuntzakis fixed a case of spurious SSL connection aborts using
  libcurl and OpenSSL. "I tracked it down to uncleared error state on the
  OpenSSL error stack - patch attached deals with that."

Daniel Stenberg (5 June 2010)
- Frank Meier added CURLINFO_PRIMARY_PORT, CURLINFO_LOCAL_IP and
  CURLINFO_LOCAL_PORT to curl_easy_getinfo().

Yang Tse (4 June 2010)
- Enabled OpenLDAP support for cygwin builds. This support was disabled back
  in 2008 due to incompatibilities between OpenSSL and OpenLDAP headers.
  cygwin's OpenSSL 0.9.8l and OpenLDAP 2.3.43 versions on cygwin 1.5.25
  allow building an OpenLDAP enabled libcurl supporting back to Windows 95.

  Removed the non-functional CURL_LDAP_HYBRID code and references.

Daniel Stenberg (2 June 2010)
- Jason McDonald posted bug report #3006786 when he found that the SFTP code
  didn't timeout properly in several places in the code even if a timeout was
  set properly.

  Based on his suggested patch, I wrote a different implementation that I
  think addressed the issue better and also uses the connect timeout for the
  initial part of the SSH/SFTP done during the "protocol connect" phase.

  (https://curl.haxx.se/bug/view.cgi?id=3006786)

Yang Tse (2 June 2010)
- Added missing new libcurl files to non-configure targets. Adjusted
  libcurl standard internal header inclusions in new files. Fixed an
  SPNEGO related memory leak. Fixed several LDAP related compilation
  issues, and fixed some compiler warnings.

Daniel Stenberg (1 June 2010)
- Igor Novoseltsev reported a problem with the multi socket API and using
  timeouts and timers. It boiled down to a problem with libcurl's use of
  GetTickCount() interally to figure out the current time, while Igor's own
  application code used another function call.

  It made his app call the socket API timeout function a bit _before_ libcurl
  would consider the timeout to trigger, and that could easily lead to
  timeouts or stalls in the app. It seems GetTickCount() in general often has
  no better resolution than 16ms and switching to the alternative function
  QueryPerformanceCounter has its share of problems:
      http://www.virtualdub.org/blog/pivot/entry.php?id=106

  We address this problem by simply having libcurl treat timers that already
  has occured or will occur within 40ms subject for treatment. I'm confident
  that there are other implementations and operating systems with similarly in
  accurate timer functions so it makes sense to have applied generically and I
  don't believe we sacrifice much by adding a 40ms inaccuracy on these
  timeouts.

Kamil Dudka (27 May 2010)
- added a new test for CRL support (test313)

- Tor Arntsen changed the alternative definition of bool to use enum instead
  of unsigned char.

Daniel Stenberg (25 May 2010)
- Julien Chaffraix fixed the warning seen when compiling lib/rtmp.c: one
  unused variables, several unused arguments and some missing #include.

- Julien Chaffraix fixed 2 OOM errors: a missing NULL-check in
  lib/http_negociate.c and a potential NULL dereferencing in lib/splay.c

- Howard Chu brought a patch that makes the LDAP code much cleaner, nicer and
  in general being a better libcurl citizen. If a new enough OpenLDAP version
  is detect, the new and shiny lib/openldap.c code is then used instead of the
  old cruft.

Daniel Stenberg (21 May 2010)
- Eric Mertens posted bug #3003705: when we made TFTP use the correct timeout
  option when sent to the server (fixed May 18th 2010) it became obvious that
  libcurl used invalid timeout values (300 by default while the RFC allows
  nothing above 255). While of course it is obvious that as TFTP has worked
  thus far without being able to set timeout at all, just removing the setting
  wouldn't make any difference in behavior. I decided to still keep it (but
  fix the problem) as it now actually allows for easier (future) customization
  of the timeout.

  (https://curl.haxx.se/bug/view.cgi?id=3003705)

- Douglas Kilpatrick filed bug report #3004787 and pointed out that the TFTP
  code didn't handle block id wraps correctly. His suggested fix inspired the
  fix I committed.

  (https://curl.haxx.se/bug/view.cgi?id=3004787)

Daniel Stenberg (20 May 2010)
- Tanguy Fautre brought a fix to allow curl to build with Microsoft VC10.

Daniel Stenberg (18 May 2010)
- Eric Mertens posted bug report #3003005 pointing out that the libcurl TFTP
  code was not sending the timeout option properly to the server, and
  suggested a fix.

  (https://curl.haxx.se/bug/view.cgi?id=3003005)

Kamil Dudka (16 May 2010)
- Pavel Raiskup introduced a new option CURLOPT_FNMATCH_DATA in order to pass
  a custom data pointer to the callback specified by CURLOPT_FNMATCH_FUNCTION.

Daniel Stenberg (14 May 2010)
- John-Mark Bell filed bug #3000052 that identified a problem (with an
  associated patch) with the OpenSSL handshake state machine when the multi
  interface is used:

  Performing an https request using a curl multi handle and using select or
  epoll to wait for events results in a hang. It appears that the cause is the
  fix for bug #2958179, which makes ossl_connect_common unconditionally return
  from the step 2 loop when fetching from a multi handle.

  When ossl_connect_step2 has completed, it updates connssl->connecting_state
  to ssl_connect_3. ossl_connect_common will then return to the caller, as a
  multi handle is in use. Eventually, the client code will call
  curl_multi_fdset to obtain an updated fdset to select or epoll on. For https
  requests, curl_multi_fdset will cause https_getsock to be called.
  https_getsock will only return a socket handle if the connecting_state is
  ssl_connect_2_reading or ssl_connect_2_writing.  Therefore, the client will
  never obtain a valid fdset, and thus not drive the multi handle, resulting
  in a hang.

  (https://curl.haxx.se/bug/view.cgi?id=3000052)

- Sebastian V reported bug #3000056 identifying a problem with redirect
  following. It showed that when curl followed redirects it didn't properly
  ignore the response body of the 30X response if that response was using
  compressed Content-Encoding!

  (https://curl.haxx.se/bug/view.cgi?id=3000056)

Daniel Stenberg (12 May 2010)
- Howard Chu brought support for RTMP. This is powered by the underlying
  librtmp library. It supports a range of variations and "sub-protocols"
  within the RTMP family.

- Pavel Raiskup brought support for FTP directory wildcard matching to allow
  selective downloading. To provide that, a set of new options were added:

   CURLOPT_WILDCARDMATCH
   CURLOPT_CHUNK_BGN_FUNCTION
   CURLOPT_CHUNK_END_FUNCTION
   CURLOPT_CHUNK_DATA
   CURLOPT_FNMATCH_FUNCTION

  There were also a set of new tests added (574 - 577) to verify this.

Kamil Dudka (11 May 2010)
- CRL support in libcurl-NSS has been completely broken. Now it works. Original
  bug report: https://bugzilla.redhat.com/581926

Daniel Stenberg (7 May 2010)
- Dirk Manske reported a regression. When connecting with the multi interface,
  there were situations where libcurl wouldn't store connect time correctly as
  it used to (and is documented to) do.

  Using his fine sample program we could repeat it, and I wrote up test case
  573 using that code. The problem does not easily show itself using the local
  test suite though.

  The fix, also as suggested by Dirk, is a bit on the ugly side as it adds yet
  another call to Curl_verboseconnect() and setting the TIMER_CONNECT time.
  That situation is subject for some closer inspection in the future.

- Howard Chu split the I/O handling functions into private handlers.

  Howard Chu brought the bulk work of this patch that properly moves out the
  sending and recving of data to the parts of the code that are properly
  responsible for the various ways of doing so.

  Daniel Stenberg assisted with polishing a few bits and fixed some minor
  flaws in the original patch.

  Another upside of this patch is that we now abuse CURLcodes less with the
  "magic" -1 return codes and instead use CURLE_AGAIN more consistently.

Daniel Stenberg (5 May 2010)
- Hoi-Ho Chan introduced support for using the PolarSSL library. You control
  this with the new configure option --with-polarssl.

Daniel Stenberg (29 Apr 2010)
- Ben Greear made telnet a lot better/easier to use by an application:

  The main change is to allow input from user-specified methods, when they are
  specified with CURLOPT_READFUNCTION.  All calls to fflush(stdout) in
  telnet.c were removed, which makes using 'curl telnet://foo.com' painful
  since prompts and other data are not always returned to the user promptly.
  Use 'curl --no-buffer telnet://foo.com' instead.  In general, the user
  should have their CURLOPT_WRITEFUNCTION do a fflush for interactive use.

  Also fix assumption that reading from stdin never returns < 0.
  Old code could crash in that case.

  Call progress functions in telnet main loop.

Daniel Stenberg (26 Apr 2010)
- Make use of the libssh2_init/exit functions that libssh2 added in version
  1.2.5. Using them will improve how libcurl works in threaded situations when
  SCP and SFTP are transfered.

Daniel Stenberg (25 Apr 2010)
- Based on work by Kamil Dudka, I've introduced the new configure option
  --enable-threaded-resolver. When used, the configure script will check for
  pthreads and if around, it will build libcurl to use pthreads to do name
  resolving in a threaded manner. Note that this is just a fix to offer an
  option that can enable the code that already included. The threader resolver
  code was mostly added on Jan 26 2010.

Daniel Stenberg (24 Apr 2010)
- Alex Bligh introduced the --proto and -proto-redir options that limit what
  protocols curl accepts for the requests and when following redirects.

Kamil Dudka (24 Apr 2010)
- Fixed test536 in order to not fail with threaded DNS resolver and tweaked
  comments in certain examples using curl_multi_fdset().

- Fixed SSL handshake timeout underflow in libcurl-NSS, which caused test405
  to hang on a slow machine.

Daniel Stenberg (21 Apr 2010)
- The -O option caused curl to crash on windows and DOS due to the tool
  writing out of boundary memory.

Yang Tse (20 Apr 2010)
- Ruslan Gazizov detected that MSVC makefiles were using wsock32.lib instead
  of ws2_32.lib, this generated linking issues on MSVC IPv6 enabled builds
  that were done using those makefiles.

Daniel Stenberg (19 Apr 2010)
- -J/--remote-header-name didn't strip trailing carriage returns or linefeeds
  properly, so they could be used in the file name.

Daniel Stenberg (16 Apr 2010)
- Jerome Vouillon made the GnuTLS SSL handshake phase non-blocking.

- The recent overhaul of the SSL recv function made the GnuTLS specific code
  treat a zero returned from gnutls_record_recv() as an error, and this caused
  our HTTPS test cases to fail. We leave it to upper layer code to detect if
  an EOF is a problem or not.

- I reverted the resolver fix from yesterday and instead removed all uses of
  AI_CANONNAME all over libcurl and made the only user of that info (krb5.c)
  use the host name from the URL instead. No reverse resolving is a good
  thing.

- Paul Howarth made configure properly detect GSS "on ancient Linux distros"
  by editing in which order we use headers to detect GSS.

Daniel Stenberg (15 Apr 2010)
- Rainer Canavan filed bug report #2987196 that identified libcurl doing
  unnecesary reverse name lookups in many cases when built to use IPv4 and
  getaddrinfo(). The logic for IPv6 is now used for IPv4 too.

  (https://curl.haxx.se/bug/view.cgi?id=2963679)

Version 7.20.1 (14 April 2010)

Daniel Stenberg (9 Apr 2010)
- Prefixing the FTP quote commands with an asterisk really only worked for the
  postquote actions. This is now fixed and test case 227 has been extended to
  verify.

Kamil Dudka (4 Apr 2010)
- Eliminated a race condition in Curl_resolv_timeout().

- Refactorized interface of Curl_ssl_recv()/Curl_ssl_send().

- libcurl-NSS now provides more accurate messages and error codes in case of
  client certificate problem.  Either during connection, or transfer phase.

Daniel Stenberg (1 Apr 2010)
- Matt Wixson found and fixed a bug in the SCP/SFTP area where the code
  treated a 0 return code from libssh2 to be the same as EAGAIN while in
  reality it isn't. The problem caused a hang in SFTP transfers from a
  MessageWay server.

Daniel Stenberg (28 Mar 2010)
- Ben Greear: If you pass a URL to pop3 that does not contain a message ID as
  part of the URL, it would previously ask for 'INBOX' which just causes the
  pop3 server to return an error.

  Now libcurl treats en empty message ID as a request for LIST (list of pop3
  message IDs).  User's code could then parse this and download individual
  messages as desired.

Daniel Stenberg (27 Mar 2010)
- Ben Greear brought a patch that from now on allows all protocols to specify
  name and user within the URL, in the same manner HTTP and FTP have been
  allowed to in the past - although far from all of the libcurl supported
  protocls actually have that feature in their URL definition spec.

Daniel Stenberg (26 Mar 2010)
- Ben Greear brought code that makes the rate limiting code for the easy
  interface a bit smoother as it introduces sub-second sleeps during it and it
  also takes the buffer sizes into account.

Daniel Stenberg (24 Mar 2010)
- Bob Richmond: There's an annoying situation where libcurl will read new HTTP
  response data from a socket, then check if it's a timeout if one is set. If
  the last packet received constitutes the end of the response body, libcurl
  still treats it as a timeout condition and reports a message like:

  "Operation timed out after 3000 milliseconds with 876 out of 876 bytes
  received"

  It should only a timeout if the timer lapsed and we DIDN'T receive the end
  of the response body yet.

- Christopher Conroy fixed a problem with RTSP and GET_PARAMETER reported
  to us by Massimo Callegari. There's a new test case 572 that verifies this
  now.

- The 'ares' subtree has been removed from the source repository. It was
  always a separate project that sort of piggybacked on the curl project since
  the dawn of times and now the time has come for it to go stand on its own
  legs and continue living its own life. All details on c-ares and its new
  source code repository is found at http://c-ares.haxx.se/

Daniel Stenberg (23 Mar 2010)
- Kenny To filed the bug report #2963679 with patch to fix a problem he
  experienced with doing multi interface HTTP POST over a proxy using
  PROXYTUNNEL. He found a case where it would connect fine but bits.tcpconnect
  was not set correct so libcurl didn't work properly.

  (https://curl.haxx.se/bug/view.cgi?id=2963679)

- Akos Pasztory filed debian bug report #572276
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572276 mentioning a problem
  with a resource that returns chunked-encoded _and_ with a Content-Length
  and libcurl failed to properly ignore the latter information.

- Hauke Duden provided an example program that made the multi interface crash.
  His example simply used the multi interface and did first one FTP transfer
  and after completion it used a second easy handle and did another FTP
  transfer on the same FTP server.

  This triggered a bug in the "delayed easy handle kill" system that curl
  uses: when an FTP connection is left alive it must keep an easy handle
  around internally - only for the purpose of having an easy handle when it
  later disconnects it. The code assumed that when the easy handle was removed
  and an internal reference was made, that version could be killed later on
  when a new easy handle came using the same connection. This was wrong as
  Hauke's example showed that the removed handle wasn't killed for real until
  later. This caused a double close attempt => segfault.

Daniel Stenberg (22 Mar 2010)
- Thomas Lopatic fixed the alarm()-based DNS timeout:

  Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in
  case of a timeout, the signal handler for SIGALRM never gets removed. I
  think that in my case it gets executed at some point later on when execution
  has long left Curl_resolv_timeout() or even the cURL library.

  The code that is jumped to with siglongjmp() simply sets the error message
  to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess
  that instead of simply returning without cleaning up, the code should have a
  goto that jumps to the spot right after the call to Curl_resolv().

Kamil Dudka (22 Mar 2010)
- Douglas Steinwand contributed a patch fixing insufficient initialization in
  Curl_clone_ssl_config()

Daniel Stenberg (21 Mar 2010)
- Ben Greear improved TFTP: the error code returning and the treatment
  of TSIZE == 0 when uploading.

- We've switched from CVS to git. See https://curl.haxx.se/source.html

Kamil Dudka (19 Mar 2010)
- Improved Curl_read() to not ignore the error returned from Curl_ssl_recv().

Daniel Stenberg (15 Mar 2010)
- Constantine Sapuntzakis brought a patch:

  The problem mentioned on Dec 10 2009
  (https://curl.haxx.se/bug/view.cgi?id=2905220) was only partially fixed.
  Partially because an easy handle can be associated with many connections in
  the cache (e.g. if there is a redirect during the lifetime of the easy
  handle).  The previous patch only cleaned up the first one. The new fix now
  removes the easy handle from all connections, not just the first one.

Daniel Stenberg (6 Mar 2010)
- Ben Greear brought a patch that fixed the rate limiting logic for TFTP when
  the easy interface was used.

Daniel Stenberg (5 Mar 2010)
- Daniel Johnson provided fixes for building curl with the clang compiler.

Yang Tse (5 Mar 2010)
- Constantine Sapuntzakis detected and fixed a double free in builds done
  with threaded resolver enabled (Windows default configuration) that would
  get triggered when a curl handle is closed while doing DNS resolution.

Daniel Stenberg (2 Mar 2010)
- [Daniel Johnson] I've been trying to build libcurl with clang on Darwin and
  ran into some issues with the GSSAPI tests in configure.ac. The tests first
  try to determine the include dirs and libs and set CPPFLAGS and LIBS
  accordingly. It then checks for the headers and finally sets LIBS a second
  time, causing the libs to be included twice. The first setting of LIBS seems
  redundant and should be left out, since the first part is otherwise just
  about finding headers.

  My second issue is that 'krb5-config --libs gssapi' on Darwin is less than
  useless and returns junk that, while it happens to work with gcc, causes
  clang to choke. For example, --libs returns $CFLAGS along with the libs,
  which is really retarded. Simply setting 'LIBS="$LIBS -lgssapi_krb5
  -lresolv"' on Darwin is sufficient.

- Based on patch provided by Jacob Moshenko, the transfer logic now properly
  makes sure that when using sub-second timeouts, there's no final bad 1000ms
  wait. Previously, a sub-second timeout would often make the elapsed time end
  up the time rounded up to the nearest second (e.g. 1s for 200ms timeout)

- Andrei Benea filed bug report #2956698 and pointed out that the
  CURLOPT_CERTINFO feature leaked memory due to a missing OpenSSL function
  call. He provided the patch to fix it too.

  https://curl.haxx.se/bug/view.cgi?id=2956698

- Markus Duft pointed out in bug #2961796 that even though Interix has a
  poll() function it doesn't quite work the way we want it so we must disable
  it, and he also provided a patch for it.

  https://curl.haxx.se/bug/view.cgi?id=2961796

- Made the pingpong timeout code properly deal with the response timeout AND
  the global timeout if set. Also, as was reported in the bug report #2956437
  by Ryan Chan, the time stamp to use as basis for the per command timeout was
  not set properly in the DONE phase for FTP (and not for SMTP) so I fixed
  that just now. This was a regression compared to 7.19.7 due to the
  conversion of FTP code over to the generic pingpong concepts.

  https://curl.haxx.se/bug/view.cgi?id=2956437

Daniel Stenberg (1 Mar 2010)
- Ben Greear provided an update for TFTP that fixes upload.

- Wesley Miaw reported bug #2958179 which identified a case of looping during
  OpenSSL based SSL handshaking even though the multi interface was used and
  there was no good reason for it.

  https://curl.haxx.se/bug/view.cgi?id=2958179

Daniel Stenberg (26 Feb 2010)
- Pat Ray in bug #2958474 pointed out an off-by-one case when receiving a
  chunked-encoding trailer.

  https://curl.haxx.se/bug/view.cgi?id=2958474

Daniel Fandrich (25 Feb 2010)
- Fixed a couple of out of memory leaks and a segfault in the SMTP & IMAP code.

Yang Tse (25 Feb 2010)
- I fixed bug report #2958074 indicating
  (https://curl.haxx.se/bug/view.cgi?id=2958074) that curl on Windows with
  option --trace-time did not use local time when timestamping trace lines.
  This could also happen on other systems depending on time souurce.

Patrick Monnerat (22 Feb 2010)
- Proper handling of STARTTLS on SMTP, taking CURLUSESSL_TRY into account.
- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
- Use of true local host name (i.e.: via gethostname()) when available, as
  default argument to SMTP HELO/EHLO.
- Test case 804 for HELO fallback.

Daniel Stenberg (20 Feb 2010)
- Fixed the SMTP compliance by making sure RCPT TO addresses are specified
  properly in angle brackets. Recipients provided with CURLOPT_MAIL_RCPT now
  get angle bracket wrapping automatically by libcurl unless the recipient
  starts with an angle bracket as then the app is assumed to deal with that
  properly on its own.

- I made the SMTP code expect a 250 response back from the server after the
  full DATA has been sent, and I modified the test SMTP server to also send
  that response. As usual, the DONE operation that is made after a completed
  transfer is still not doable in a non-blocking way so this waiting for 250
  is unfortunately made blockingly.

Yang Tse (14 Feb 2010)
- Overhauled test suite getpart() function. Fixing potential out of bounds
  stack and memory overwrites triggered with huge test case definitions.

Daniel Stenberg (13 Feb 2010)
- Martin Hager reported and fixed a problem with a missing quote in libcurl.m4

  (https://curl.haxx.se/bug/view.cgi?id=2951319)

- Tom Donovan fixed the CURL_FORMAT_* defines when building with cmake.

  (https://curl.haxx.se/bug/view.cgi?id=2951269)

Daniel Stenberg (12 Feb 2010)
- Jack Zhang reported a problem with SMTP: we wrongly used multiple addresses
  in the same RCPT TO line, when they should be sent in separate single
  commands. I updated test case 802 to verify this.

- I also fixed a bad use of my_setopt_str() of CURLOPT_MAIL_RCPT in the curl
  tool which made it try to output it as string for the --libcurl feature
  which could lead to crashes.

Yang Tse (11 Feb 2010)
- Steven M. Schweda fixed VMS builder bad behavior when used in a batch job,
  removed obsolete batch_compile.com and defines.com and updated VMS readme.

Version 7.20.0 (9 February 2010)

Daniel Stenberg (9 Feb 2010)
- When downloading compressed content over HTTP and the app asked libcurl to
  automatically uncompress it with the CURLOPT_ENCODING option, libcurl could
  wrongly provide the callback with more data than the maximum documented
  amount. An application could thus get tricked into badness if the maximum
  limit was trusted to be enforced by libcurl itself (as it is documented).

  This is further detailed and explained in the libcurl security advisory
  20100209 at

    https://curl.haxx.se/docs/adv_20100209.html

Daniel Fandrich (3 Feb 2010)
- Changed the Watcom makefiles to make them easier to keep in sync with
  Makefile.inc since that can't be included directly.

Yang Tse (2 Feb 2010)
- Symbol CURL_FORMAT_OFF_T now obsoleted, will be removed in a future release,
  symbol will not be available when building with CURL_NO_OLDIES defined. Use
  of CURL_FORMAT_CURL_OFF_T is preferred since 7.19.0

Daniel Stenberg (1 Feb 2010)
- Using the multi_socket API, it turns out at times it seemed to "forget"
  connections (which caused a hang). It turned out to be an existing (7.19.7)
  bug in libcurl (that's been around for a long time) and it happened like
  this:

  The app calls curl_multi_add_handle() to add a new easy handle, libcurl will
  then set it to timeout in 1 millisecond so libcurl will tell the app about
  it.

  The app's timeout fires off that there's a timeout, the app calls libcurl as
  we so often document it:

  do {
   res = curl_multi_socket_action(... TIMEOUT ...);
  } while(CURLM_CALL_MULTI_PERFORM == res);

  And this is the problem number one:

  When curl_multi_socket_action() is called with no specific handle, but only
  a timeout-action, it will *only* perform actions within libcurl that are
  marked to run at this time. In this case, the request would go from INIT to
  CONNECT and return CURLM_CALL_MULTI_PERFORM. When the app then calls libcurl
  again, there's no timer set for this handle so it remains in the CONNECT
  state. The CONNECT state is a transitional state in libcurl so it reports no
  sockets there, and thus libcurl never tells the app anything more about that
  easy handle/connection.

  libcurl _does_ set a 1ms timeout for the handle at the end of
  multi_runsingle() if it returns CURLM_CALL_MULTI_PERFORM, but since the loop
  is instant the new job is not ready to run at that point (and there's no
  code that makes libcurl call the app to update the timout for this new
  timeout). It will simply rely on that some other timeout will trigger later
  on or that something else will update the timeout callback. This makes the
  bug fairly hard to repeat.

  The fix made to adress this issue:

  We introduce a loop in lib/multi.c around all calls to multi_runsingle() and
  simply check for CURLM_CALL_MULTI_PERFORM internally. This has the added
  benefit that this goes in line with my long-term wishes to get rid of the
  CURLM_CALL_MULTI_PERFORM all together from the public API.

  The downside of this fix, is that the counter we return in 'running_handles'
  in several of our public functions then gets a slightly new and possibly
  confusing behavior during times:

  If an app adds a handle that fails to connect (very quickly) it may just
  as well never appear as a 'running_handle' with this fix. Previously it
  would first bump the counter only to get it decreased again at next call.
  Even I have used that change in handle counter to signal "end of a
  transfer". The only *good* way to find the end of a individual transfer
  is calling curl_multi_info_read() to see if it returns one.

  Of course, if the app previously did the looping before it checked the
  counter, it really shouldn't be any new effect.

Yang Tse (26 Jan 2010)
- Constantine Sapuntzakis' and Joshua Kwan's work done in the last four months
  relative to the asynchronous DNS lookups, along with with some integration
  adjustments I have done are finally committed to CVS.

  Currently these enhancements will benefit builds done using c-ares on any
  platform as well as Windows builds using the default threaded resolver.

  This release does not make generally available POSIX threaded DNS lookups
  yet. There is no configure option to enable this feature yet. It is possible
  to experimantally try this feature running configure with compiler flags that
  make simultaneous definition of preprocessor symbols USE_THREADS_POSIX and
  HAVE_PTHREAD_H, as well as whatever reentrancy compiler flags and linker ones
  are required to link and properly use pthread_* functions on each platform.

Daniel Stenberg (26 Jan 2010)
- Mike Crowe made libcurl return CURLE_COULDNT_RESOLVE_PROXY when it is the
  proxy that cannot be resolved when using c-ares. This matches the behaviour
  when not using c-ares.

Björn Stenberg (23 Jan 2010)
- Added a new flag: -J/--remote-header-name. This option tells the
  -O/--remote-name option to use the server-specified Content-Disposition
  filename instead of extracting a filename from the URL.

Daniel Stenberg (21 Jan 2010)
- Chris Conroy brought support for RTSP transfers, and with it comes 8(!) new
  libcurl options for controlling what to get and how to receive posssibly
  interleaved RTP data.

Daniel Stenberg (20 Jan 2010)
- As was pointed out on the http-state mailing list, the order of cookies in a
  HTTP Cookie: header _needs_ to be sorted on the path length in the cases
  where two cookies using the same name are set more than once using
  (overlapping) paths. Realizing this, identically named cookies must be
  sorted correctly. But detecting only identically named cookies and take care
  of them individually is harder than just to blindly and unconditionally sort
  all cookies based on their path lengths. All major browsers also already do
  this, so this makes our behavior one step closer to them in the cookie area.

  Test case 8 was the only one that broke due to this change and I updated it
  accordingly.

Daniel Stenberg (19 Jan 2010)
- David McCreedy brought a fix and a new test case (129) to make libcurl work
  again when downloading files over FTP using ASCII and it turns out that the
  final size of the file is not the same as the initial size the server
  reported. This is very common since servers don't take the newline
  conversions into account.

Kamil Dudka (14 Jan 2010)
- Suppressed side effect of OpenSSL configure checks, which prevented NSS from
  being properly detected under certain circumstances. It had been caused by
  strange behavior of pkg-config when handling PKG_CONFIG_LIBDIR. pkg-config
  distinguishes among empty and non-existent environment variable in that case.

Daniel Stenberg (12 Jan 2010)
- Gil Weber reported a peculiar flaw with the multi interface when doing SFTP
  transfers: curl_multi_fdset() would return -1 and not set and file
  descriptors several times during a transfer of a single file. It turned out
  to be due to two different flaws now fixed. Gil's excellent recipe helped me
  nail this.

Daniel Stenberg (11 Jan 2010)
- Made sure that the progress callback is repeatedly called at a regular
  interval even during very slow connects.

- The tests/runtests.pl script now checks to see if the test case that runs is
  present in the tests/data/Makefile.am and outputs a notice message on the
  screen if not. Each test file has to be included in that Makefile.am to get
  included in release archives and forgetting to add files there is a common
  mistake. This is an attempt to make it harder to forget.

Daniel Stenberg (9 Jan 2010)
- Johan van Selst found and fixed a OpenSSL session ref count leak:

  ossl_connect_step3() increments an SSL session handle reference counter on
  each call. When sessions are re-used this reference counter may be
  incremented many times, but it will be decremented only once when done (by
  Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
  if this reference count remains positive. When a session is re-used the
  reference counter should be corrected by explicitly calling
  SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
  introducing a memory leak.

  (https://curl.haxx.se/bug/view.cgi?id=2926284)

Daniel Stenberg (7 Jan 2010)
- Make sure the progress callback is called repeatedly even during very slow
  name resolves when c-ares is used for resolving.

Claes Jakobsson (6 Jan 2010)
- Julien Chaffraix fixed so that the fragment part in an URL is not sent
  to the server anymore.

Kamil Dudka (3 Jan 2010)
- Julien Chaffraix eliminated a duplicated initialization in singlesocket().

Daniel Stenberg (2 Jan 2010)
- Make curl support --ssl and --ssl-reqd instead of the previous FTP-specific
  versions --ftp-ssl and --ftp-ssl-reqd as these options are now used to
  control SSL/TLS for IMAP, POP3 and SMTP as well in addition to FTP. The old
  option names are still working but the new ones are the ones listed and
  documented.

Daniel Stenberg (1 Jan 2010)
- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This
  command is a special "hack" used by the drftpd server, but even though it is
  a custom extension I've deemed it fine to add to libcurl since this server
  seems to survive and people keep using it and want libcurl to support
  it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
  usable from the curl tool with --ftp-pret. Using this option on a server
  that doesn't support this command will make libcurl fail.

  I added test cases 1107 and 1108 to verify the functionality.

  The PRET command is documented at
  http://www.drftpd.org/index.php/Distributed_PASV

Yang Tse (30 Dec 2009)
- Steven M. Schweda improved VMS build system, and Craig A. Berry helped
  with the patch and testing.

Daniel Stenberg (26 Dec 2009)
- Renato Botelho and Peter Pentchev brought a patch that makes the libcurl
  headers work correctly even on FreeBSD systems before v8.

  (https://curl.haxx.se/bug/view.cgi?id=2916915)

Daniel Stenberg (17 Dec 2009)
- David Byron fixed Curl_ossl_cleanup to actually call ENGINE_cleanup when
  available.

- Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I
  was a bit too quick and broke test case 1101 with that change. The order of
  some of the setups is sensitive. I now changed it slightly again to make
  sure we do them in this order:

  1 - parse URL and figure out what protocol is used in the URL
  2 - prepend protocol:// to URL if missing
  3 - parse name+password off URL, which needs to know what protocol is used
      (since only some allows for name+password in the URL)
  4 - figure out if a proxy should be used set by an option
  5 - if no proxy option, check proxy environment variables
  6 - run the protocol-specific setup function, which needs to have the proxy
      already set

Daniel Stenberg (15 Dec 2009)
- Jon Nelson found a regression that turned out to be a flaw in how libcurl
  detects and uses proxies based on the environment variables. If the proxy
  was given as an explicit option it worked, but due to the setup order
  mistake proxies would not be used fine for a few protocols when picked up
  from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
  test case 1106 that verifies this functionality.

  (https://curl.haxx.se/bug/view.cgi?id=2913886)

Daniel Stenberg (12 Dec 2009)
- IMAP, POP3 and SMTP support and their TLS versions (including IMAPS, POP3S
  and SMTPS) are now supported. The current state may not yet be solid, but
  the foundation is in place and the test suite has some initial support for
  these protocols. Work will now persue to make them nice libcurl citizens
  until release.

  The work with supporting these new protocols was sponsored by
  networking4all.com - thanks!

Daniel Stenberg (10 Dec 2009)
- Siegfried Gyuricsko found out that the curl manual said --retry would retry
  on FTP errors in the transient 5xx range. Transient FTP errors are in the
  4xx range. The code itself only tried on 5xx errors that occured _at login_.
  Now the retry code retries on all FTP transfer failures that ended with a
  4xx response.

  (https://curl.haxx.se/bug/view.cgi?id=2911279)

- Constantine Sapuntzakis figured out a case which would lead to libcurl
  accessing alredy freed memory and thus crash when using HTTPS (with
  OpenSSL), multi interface and the CURLOPT_DEBUGFUNCTION and a certain order
  of cleaning things up. I fixed it.

  (https://curl.haxx.se/bug/view.cgi?id=2905220)

Daniel Stenberg (7 Dec 2009)
- Martin Storsjo made libcurl use the Expect: 100-continue header for posts
  with unknown size. Previously it was only used for posts with a known size
  larger than 1024 bytes.

Daniel Stenberg (1 Dec 2009)
- If the Expect: 100-continue header has been set by the application through
  curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
  data->state.expect100header accordingly - the current code (in 7.19.7 at
  least) doesn't handle this properly. Martin Storsjo provided the fix!

Yang Tse (28 Nov 2009)
- Added Diffie-Hellman parameters to several test harness certificate files in
  PEM format. Required by several stunnel versions used by our test harness.

Daniel Stenberg (28 Nov 2009)
- Markus Koetter provided a polished and updated version of Chad Monroe's TFTP
  rework patch that now integrates TFTP properly into libcurl so that it can
  be used non-blocking with the multi interface and more. BLKSIZE also works.

  The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
  the command line.

Daniel Stenberg (26 Nov 2009)
- Extended and fixed the change I did on Dec 11 for the the progress
  meter/callback during FTP command/response sequences. It turned out it was
  really lame before and now the progress meter SHOULD get called at least
  once per second.

Daniel Stenberg (23 Nov 2009)
- Bjorn Augustsson reported a bug which made curl not report any problems even
  though it failed to write a very small download to disk (done in a single
  fwrite call). It turned out to be because fwrite() returned success, but
  there was insufficient error-checking for the fclose() call which tricked
  curl to believe things were fine.

Yang Tse (23 Nov 2009)
- David Byron modified Makefile.dist vc8 and vc9 targets in order to allow
  finer granularity control when generating src and lib makefiles.

Yang Tse (22 Nov 2009)
- I modified configure to force removal of the curlbuild.h file included in
  distribution tarballs for use by non-configure systems. As intended, this
  would get overwriten when doing in-tree builds. But VPATH builds would end
  having two curlbuild.h files, one in the source tree and another in the
  build tree. With the modification I introduced 5 Nov 2009 this could become
  an issue when running libcurl's test suite.

Daniel Stenberg (20 Nov 2009)
- Constantine Sapuntzakis identified a write after close, as the sockets were
  closed by libcurl before the SSL lib were shutdown and they may write to its
  socket. Detected to at least happen with OpenSSL builds.

- Jad Chamcham pointed out a bug with connection re-use. If a connection had
  CURLOPT_HTTPPROXYTUNNEL enabled over a proxy, a subsequent request using the
  same proxy with the tunnel option disabled would still wrongly re-use that
  previous connection and the outcome would only be badness.

Yang Tse (18 Nov 2009)
- I modified the memory tracking system to make it intolerant with zero sized
  malloc(), calloc() and realloc() function calls.

Daniel Stenberg (17 Nov 2009)
- Constantine Sapuntzakis provided another fix for the DNS cache that could
  end up with entries that wouldn't time-out:

  1. Set up a first web server that redirects (307) to a http://server:port
     that's down
  2. Have curl connect to the first web server using curl multi

  After the curl_easy_cleanup call, there will be curl dns entries hanging
  around with in_use != 0.

  (https://curl.haxx.se/bug/view.cgi?id=2891591)

- Marc Kleine-Budde fixed: curl saved the LDFLAGS set during configure into
  its pkg-config file.  So -Wl stuff ended up in the .pc file, which is really
  bad, and breaks if there are multiple -Wl in our LDFLAGS (which are in
  PTXdist). bug #2893592 (https://curl.haxx.se/bug/view.cgi?id=2893592)

Kamil Dudka (15 Nov 2009)
- David Byron improved the configure script to use pkg-config to find OpenSSL
  (and in particular the list of required libraries) even if a path is given
  as argument to --with-ssl

Yang Tse (15 Nov 2009)
- I removed enable-thread / disable-thread configure option. These were only
  placebo options. The library is always built as thread safe as possible on
  every system.

Claes Jakobsson (14 Nov 2009)
- curl-config now accepts '--configure' to see what arguments was
  passed to the configure script when building curl.

Daniel Stenberg (14 Nov 2009)
- Claes Jakobsson restored the configure functionality to detect NSS when
  --with-nss is set but not "yes".

  I think we can still improve that to check for pkg-config in that path etc,
  but at least this patch brings back the same functionality we had before.

- Camille Moncelier added support for the file type SSL_FILETYPE_ENGINE for
  the client certificate. It also disable the key name test as some engines
  can select a private key/cert automatically (When there is only one key
  and/or certificate on the hardware device used by the engine)

Yang Tse (14 Nov 2009)
- Constantine Sapuntzakis provided the fix that ensures that an SSL connection
  won't be reused unless protection level for peer and host verification match.

  I refactored how preprocessor symbol _THREAD_SAFE definition is done.

Kamil Dudka (12 Nov 2009)
- Kevin Baughman provided a fix preventing libcurl-NSS from crash on doubly
  closed NSPR descriptor. The issue was hard to find, reported several times
  before and always closed unresolved. More info at the RH bug:
  https://bugzilla.redhat.com/534176

- libcurl-NSS now tries to reconnect with TLS disabled in case it detects
  a broken TLS server. However it does not happen if SSL version is selected
  manually. The approach was originally taken from PSM. Kaspar Brand helped me
  to complete the patch. Original bug reports:
  https://bugzilla.redhat.com/525496
  https://bugzilla.redhat.com/527771

Yang Tse (12 Nov 2009)
- I modified configure script to make the getaddrinfo function check also
  verify if the function is thread safe.

Yang Tse (11 Nov 2009)
- Marco Maggi reported that compilation failed when configured --with-gssapi
  and GNU GSS installed due to a missing mutual exclusion of header files in
  the Kerberos 5 code path. He also verified that my patch worked for him.

Daniel Stenberg (11 Nov 2009)
- Constantine Sapuntzakis posted bug #2891595
  (https://curl.haxx.se/bug/view.cgi?id=2891595) which identified how an entry
  in the DNS cache would linger too long if the request that added it was in
  use that long. He also provided the patch that now makes libcurl capable of
  still doing a request while the DNS hash entry may get timed out.

- Christian Schmitz noticed that the progress meter/callback was not properly
  used during the FTP connection phase (after the actual TCP connect), while
  it of course should be. I also made the speed check get called correctly so
  that really slow servers will trigger that properly too.

Kamil Dudka (5 Nov 2009)
- Dropped misleading timeouts in libcurl-NSS and made sure the SSL socket works
  in non-blocking mode.

Yang Tse (5 Nov 2009)
- I removed leading 'curl' path on the 'curlbuild.h' include statement in
  curl.h, adjusting auto-makefiles include path, to enhance portability to
  OS's without an orthogonal directory tree structure such as OS/400.

Daniel Stenberg (4 Nov 2009)
- I fixed several problems with the transfer progress meter. It showed the
  wrong percentage for small files, most notable for <1000 bytes and could
  easily end up showing more than 100% at the end. It also didn't show any
  percentage, transfer size or estimated transfer times when transferring
  less than 100 bytes.

Version 7.19.7 (4 November 2009)

Daniel Stenberg (2 Nov 2009)
- As reported independent by both Stan van de Burgt and Didier Brisebourg,
  CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when
  getting data from ldap!

Daniel Stenberg (31 Oct 2009)
- Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the
  download was 0 bytes, as libcurl would then return the size as unknown (-1)
  and not 0. I wrote a fix and test case 566 to verify it.

Daniel Stenberg (30 Oct 2009)
- Liza Alenchery mentioned a problem with re-used SCP connection when a bad
  auth is used, as it caused a crash. I failed to repeat the issue, but still
  made a change that now forces the TCP connection used for a freed SCP
  session to get closed and not be re-used.

- "Tom" posted a bug report that mentioned how libcurl did wrong when doing a
  POST using a read callback, with Digest authentication and
  "Transfer-Encoding: chunked" enforced.  I would then cause the first request
  to be wrongly sent and then basically hang until the server closed the
  connection. I fixed the problem and added test case 565 to verify it.

Daniel Stenberg (25 Oct 2009)
- Dima Barsky made the curl cookie parser accept cookies even with blank or
  unparsable expiry dates and then treat them as session cookies - previously
  libcurl would reject cookies with a date format it couldn't parse. Research
  shows that the major browser treat such cookies as session cookies. I
  modified test 8 and 31 to verify this.

Daniel Stenberg (21 Oct 2009)
- Attempt to use pkg-config for finding out libssh2 installation details
  during configure.

- A patch in bug report #2883177 (https://curl.haxx.se/bug/view.cgi?id=2883177)
  by Johan van Selst introduced the --crlfile option to curl, which makes curl
  tell libcurl about a file with CRL (certificate revocation list) data to
  read.

Daniel Stenberg (18 Oct 2009)
- Ray Dassen provided a patch in Debian's bug tracker (bug number #551461)
  that now makes curl_getdate(3) actually handles RFC 822 formatted dates that
  use the "single letter military timezones".
  http://www.rfc-ref.org/RFC-TEXTS/822/chapter5.html has the details.

- Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts
  data!

- John Dennis filed bug report #2873666
  (https://curl.haxx.se/bug/view.cgi?id=2873666) which identified a problem
  which made libcurl loop infinitely when given incorrect credentials when
  using HTTP GSS negotiate authentication. He also provided a small and simple
  patch for it.

- Kevin Baughman found a double close() problem with libcurl-NSS, as when
  libcurl called NSS to close the SSL "session" it also closed the actual
  socket.

Yang Tse (17 Oct 2009)
- Bug report #2866724 indicated
  (https://curl.haxx.se/bug/view.cgi?id=2866724) that curl on Windows failed
  when writing files whose file names originally contained characters which
  are not valid for file names on Windows. Dan Fandrich provided an initial
  patch and another revised one to fix this issue.

Daniel Stenberg (1 Oct 2009)
- Tom Mueller correctly reported in bug report #2870221
  (https://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an
  incorrect return code from the internal trynextip() function which caused
  him grief. This is a regression that was introduced in 7.19.1 and I find it
  strange it hasn't hit us harder, but I won't persue into figuring out
  exactly why.

- Constantine Sapuntzakis: The current implementation will always set
  SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger.  The
  patch doesn't do a setsockopt if SO_SNDBUF is already greater than
  CURL_WRITE_SIZE. This should help folks who have set up their computer with
  large send buffers.

Daniel Stenberg (27 Sep 2009)
- I introduced a maximum limit for received HTTP headers. It is controlled by
  the define CURL_MAX_HTTP_HEADER which is even exposed in the public header
  file to allow for users to fairly easy rebuild libcurl with a modified
  limit. The rationale for a fixed limit is that libcurl is realloc()ing a
  buffer to be able to put a full header into it, so that it can call the
  header callback with the entire header, but that also risk getting it into
  trouble if a server by mistake or willingly sends a header that is more or
  less without an end. The limit is set to 100K.

Daniel Stenberg (26 Sep 2009)
- John P. McCaskey posted a bug report that showed how libcurl did wrong when
  saving received cookies with no given path, if the path in the request had a
  query part. That is means a question mark (?) and characters on the right
  side of that. I wrote test case 1105 and fixed this problem.

Kamil Dudka (26 Sep 2009)
- Implemented a protocol independent way to specify blocking direction, used by
  transfer.c for blocking. It is currently used only by SCP and SFTP protocols.
  This enhancement resolves an issue with 100% CPU usage during SFTP upload,
  reported by Vourhey.

Daniel Stenberg (25 Sep 2009)
- Chris Mumford filed bug report #2861587
  (https://curl.haxx.se/bug/view.cgi?id=2861587) identifying that libcurl used
  the OpenSSL function X509_load_crl_file() wrongly and failed if it would
  load a CRL file with more than one certificate within. This is now fixed.

Daniel Stenberg (16 Sep 2009)
- Sven Anders reported that we introduced a cert verfication flaw for OpenSSL-
  powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
  field in the certficate it had to match and so even if non-DNS and non-IP
  entry was present it caused the verification to fail.

Daniel Fandrich (15 Sep 2009)
- Moved the libssh2 checks after the SSL library checks. This helps when
  statically linking since libssh2 needs the SSL library link flags to be
  set up already to satisfy its dependencies. This wouldn't be necessary if
  the libssh2 configure check was changed to use pkg-config since the
  --static flag would add the dependencies automatically.

Yang Tse (14 Sep 2009)
- Revert Joshua Kwan's patch committed 11 Sep 2009.

  Some systems poll function sets POLLHUP in revents without setting
  POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
  libcurl code execution paths this could trigger busy wait loops with
  high CPU usage until a timeout condition aborted the loop.

  The reverted patch addressed the above issue for a very specific case,
  when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
  superceeds this one.

Guenter Knauf (11 Sep 2009)
- Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
  This fixes a loop problem with high CPU usage.

Daniel Stenberg (10 Sep 2009)
- Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch
  start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
  which internally then is treated as a session cookie. That particular date
  is now made to get the value of 1.

Daniel Stenberg (2 Sep 2009)
- Daniel Johnson found a flaw in the code converting sftp-errors to libcurl
  errors.

Daniel Stenberg (1 Sep 2009)
- Peter Sylvester made a debug feature for Curl_resolv() that now will force
  libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
  the --interface option to (exactly) "LocalHost". This will enable us to
  write tests for custom hosts names but still use a local host server.

- configure now tries to use pkg-config for a number of sub-dependencies even
  when cross-compiling. The key to success is then you properly setup
  PKG_CONFIG_PATH before invoking configure.

  I also improved how NSS is detected by trying nss-config if pkg-config isn't
  present, and as a last resort just use the lib name and force the user to
  setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
  add a range of various libs that would almost never be quite correct.

Daniel Stenberg (31 Aug 2009)
- When using the multi interface with FTP and you asked for NOBODY, you did no
  QUOTE commands and the request used the same path as the connection had
  already changed to, it would decide that no commands would be necessary for
  the "DO" action and that was not handled properly but libcurl would instead
  hang.

Kamil Dudka (28 Aug 2009)
- Improved error message for not matching certificate subject name in
  libcurl-NSS. Originally reported at:
  https://bugzilla.redhat.com/show_bug.cgi?id=516056#c9

Patrick Monnerat (24 Aug 2009)
- Introduced a SYST-based test to properly set-up name format when dealing
  with the OS/400 FTP server.

- Fixed an ftp_readresp() bug preventing detection of failing control socket
  and causing FTP client to loop forever.

Daniel Stenberg (24 Aug 2009)
- Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work
  properly and provided a fix. https://curl.haxx.se/bug/view.cgi?id=2843008

- Eric Wong introduced support for the new option -T. (dot) that makes curl
  read stdin in a non-blocking fashion. This also brings back -T- (minus) to
  the previous blocking behavior since it could break stuff for people at
  times.

Michal Marek (21 Aug 2009)
- With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like
  ftp://example.com;type=i if the user specified ftp://example.com without the
  slash.

Daniel Stenberg (21 Aug 2009)
- Andre Guibert de Bruet pointed out a missing return code check for a
  strdup() that could lead to segfault if it returned NULL. I extended his
  suggest patch to now have Curl_retry_request() return a regular return code
  and better check that.

- Lots of good work by Krister Johansen, mostly related to pipelining:

  Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
  Fix data corruption issue with re-connected transfers
  Fix use after free if we're completed but easy_conn not NULL

Kamil Dudka (13 Aug 2009)
- Changed NSS code to not ignore the value of ssl.verifyhost and produce more
  verbose error messages. Originally reported at:
  https://bugzilla.redhat.com/show_bug.cgi?id=516056

Daniel Stenberg (12 Aug 2009)
- Karl Moerder fixed the Makefile.vc* makefiles to include the new file
  nonblock.c so that they work fine again

- I expanded test 517 with a bunch of more dates that originate from the
  Chrome browser test suite. It turns out most of them get parsed the same
  way.

Version 7.19.6 (12 August 2009)

Daniel Stenberg (12 Aug 2009)
- Carsten Lange reported a bug and provided a patch for TFTP upload and the
  sending of the TSIZE option. I don't like fixing bugs just hours before
  a release, but since it was broken and the patch fixes this for him I decided
  to get it in anyway.

Daniel Stenberg (11 Aug 2009)
- Peter Sylvester made the HTTPS test server use specific certificates for
  each test, so that the test suite can now be used to actually test the
  verification of cert names etc. This made an error show up in the OpenSSL-
  specific code where it would attempt to match the CN field even if a
  subjectAltName exists that doesn't match. This is now fixed and verified
  in test 311.

- Benbuck Nason posted the bug report #2835196
  (https://curl.haxx.se/bug/view.cgi?id=2835196), fixing a few compiler
  warnings when mixing ints and bools.

Daniel Fandrich (10 Aug 2009)
- Fixed a memory leak in the FTP code and an off-by-one heap buffer overflow.

Daniel Fandrich (9 Aug 2009)
- Fixed some memory leaks in the command-line tool that caused most of the
  torture tests to fail.

Daniel Stenberg (2 Aug 2009)
- Curt Bogmine reported a problem with SNI enabled on a particular server. We
  should introduce an option to disable SNI, but as we're in feature freeze
  now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
  shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
  Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
  option for SNI, or are we simply not using it?

Daniel Stenberg (1 Aug 2009)
- Scott Cantor posted the bug report #2829955
  (https://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert
  verification flaw found and exploited by Moxie Marlinspike. The presentation
  he did at Black Hat is available here:
  https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike

  Apparently at least one CA allowed a subjectAltName or CN that contain a
  zero byte, and thus clients that assumed they would never have zero bytes
  were exploited to OK a certificate that didn't actually match the site. Like
  if the name in the cert was "example.com\0theatualsite.com", libcurl would
  happily verify that cert for example.com.

  libcurl now better uses the length of the extracted name, not using the zero
  termination for getting the string length.

  This fixing only made and needed in OpenSSL interfacing code.

- Tanguy Fautre pointed out that OpenSSL's function RAND_screen() (present
  only in some OpenSSL installs - like on Windows) isn't thread-safe and we
  agreed that moving it to the global_init() function is a decent way to deal
  with this situation.

- Alexander Beedie provided the patch for a noproxy problem: If I have set
  CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually
  could still end up using a proxy if a proxy environment variable was set.

Daniel Stenberg (27 Jul 2009)
- All the quote options (CURLOPT_QUOTE, CURLOPT_POSTQUOTE and
  CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
  send when using FTP, as a sign that libcurl shall simply ignore the response
  from the server instead of treating it as an error. Not treating a 400+ FTP
  response code as an error means that failed commands will not abort the
  chain of commands, nor will they cause the connection to get disconnected.

Daniel Stenberg (26 Jul 2009)
- Johan van Selst posted bug report #2825989
  (https://curl.haxx.se/bug/view.cgi?id=2825989) pointing out that
  OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm, and
  provided the solution too: to use OpenSSL_add_all_algorithms() in addition
  to the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
  OpenSSL 0.9.5

Daniel Stenberg (23 Jul 2009)
- Added CURLOPT_SSH_KNOWNHOSTS, CURLOPT_SSH_KEYFUNCTION, CURLOPT_SSH_KEYDATA.
  They introduce known_host support for SSH keys to libcurl. See docs for
  details. Note that this feature depends on a new enough libssh2 version, to
  be supported in libssh2 1.2 and later (or current git repo at this time).

Michal Marek (22 Jul 2009)
- David Binderman found a memory and fd leak in lib/gtls.c:load_file()
  (https://bugzilla.novell.com/523919). When looking at the code, I found that
  also the ptr pointer can leak.

Kamil Dudka (20 Jul 2009)
- Claes Jakobsson improved the support for client certificates handling in
  NSS-powered libcurl. Now the client certificates can be selected
  automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
  slots is no more performed. It used to cause problems with HW tokens.

- Fixed reference counting for NSS client certificates. Now the PEM reader
  module should be always properly unloaded on Curl_nss_cleanup(). If the
  unload fails though, libcurl will try to reuse the already loaded instance.

Daniel Fandrich (15 Jul 2009)
- Added nonblock.c to the non-automake makefiles (note that the dependencies
  in the Watcom makefiles aren't quite correct).

Michal Marek (15 Jul 2009)
- Changed the description of CURLINFO_OS_ERRNO to make it clear that the
  errno is not reset on success.

Guenter Knauf (14 Jul 2009)
- renamed generated config.h to curl_config.h to avoid any future clashes
  with config.h from other projects.

Daniel Stenberg (9 Jul 2009)
- Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses for
  setting a file descriptor non-blocking. Used by the functionality Eric
  himself brough on June 15th.

Daniel Stenberg (8 Jul 2009)
- Constantine Sapuntzakis posted bug report #2813123
  (https://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
  problem:

  Url A is accessed using auth. Url A redirects to Url B (on a different
  server0. Url B reuses a persistent connection. Url B has auth, even though
  it's on a different server.

  Note: if Url B does not reuse a persistent connection, auth is not sent.

  reason:

  data->state.first_host is not initialized becuase Curl_http_connect is not
  called when a connection is reused.

  Solution:

  move initialization of data->state.first_host to Curl_http. No code before
  Curl_http uses data->state.first_host anyway.

Guenter Knauf (4 Jul 2009)
- Markus Koetter provided a patch to avoid getnameinfo() usage which broke a
  couple of both IPv4 and IPv6 autobuilds.

Daniel Stenberg (29 Jun 2009)
- Markus Koetter made CURLOPT_FTPPORT (and curl's -P/--ftpport) support a port
  range if given colon-separated after the host name/address part. Like
  "192.168.0.1:2000-10000"

- Modified the separators used for CURLOPT_CERTINFO in multi-part outputs. I
  don't know how they got wrong in the first place, but using this output
  format makes it possible to quite easily separate the string into an array
  of multiple items.

Daniel Fandrich (16 June 2009)
- Added a few more compiler warning options for gcc.

Daniel Stenberg (16 Jun 2009)
- Reuven Wachtfogel made curl -o - properly produce a binary output on windows
  (no newline translations). Use -B/--use-ascii if you rather get the ascii
  approach.

Michal Marek (16 Jun 2009)
- When doing non-anonymous ftp via http proxies and the password is not
  provided in the url, add it there (squid needs this).

Daniel Stenberg (15 Jun 2009)
- Eric Wong's patch:

  This allows curl(1) to be used as a client-side tunnel for arbitrary stream
  protocols by abusing chunked transfer encoding in both the HTTP request and
  HTTP response.  This requires server support for sending a response while a
  request is still being read, of course.

  If attempting to read from stdin returns EAGAIN, then we pause our sender.
  This leaves curl to attempt to read from the socket while reading from stdin
  (and thus sending) is paused.

  This change was needed to allow successfully tunneling the git protocol over
  HTTP (--no-buffer is needed, as well).

Patrick Monnerat (15 Jun 2009)
- Replaced use of standard C library rand()/srand() by our own pseudo-random
  number generator.

Yang Tse (11 Jun 2009)
- I adapted testcurl script to allow building test harness programs when
  cross-compiling for a *-*-mingw* host.

Daniel Stenberg (10 Jun 2009)
- Fabian Keil ran clang on the (lib)curl code, found a bunch of warnings and
  contributed a range of patches to fix them.

Yang Tse (10 Jun 2009)
- I introduced configure script option --enable-curldebug which now allows
  the decoupled enabling or disabling of the curl debug memory tracking
  feature from the --enable-debug option which no longer controls this.

  curl --version will list 'Debug' feature for debug enabled builds, and
  will list 'TrackMemory' feature for curl debug memory tracking capable
  builds. These features are independent and can be controlled when running
  the configure script. When --enable-debug is given both features will be
  enabled, unless some restriction prevents memory tracking from being used.

  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
  used to differentiate code which is _only_ used for memory tracking.

Yang Tse (9 Jun 2009)
- Daniel Steinberg pointed out that Curl_FormInit() in formdata.c was not
  initializing the fread callback pointer and this triggered a compiler
  warning, also provided a friendly suggestion on how to fix it.

Daniel Stenberg (8 Jun 2009)
- Claes Jakobsson provided a patch for libcurl-NSS that fixed a bad refcount
  issue with client certs that caused issues like segfaults.
  https://curl.haxx.se/mail/lib-2009-05/0316.html

- Triggered by bug report #2798852 and the patch in there, I fixed configure
  to detect gnutls build options with pkg-config only and not libgnutls-config
  anymore since GnuTLS has stopped distributing that tool. If an explicit path
  is given to configure, we will instead guess on how to link and use that
  lib. I did not use the patch from the bug report.

Yang Tse (8 Jun 2009)
- Igor Novoseltsev adjusted Makefile.vxworks to get sources and headers
  included from Makefile.inc, and provided docs\INSTALL VxWorks section.

- I removed buildconf.bat from release and daily snapshot archives. This
  file is only for CVS tree checkout builds.

Daniel Stenberg (8 Jun 2009)
- Eric Wong fixed --no-buffer to actually switch off output buffering. Been
  broken since 7.19.0

Bill Hoffman (6 Jun 2009)
- Added some cmake docs and fixed socklen_t in the build.

Yang Tse (5 Jun 2009)
- John E. Malmberg provided VMS specific patch: "This fixes an existing bug
  in urlglob.c where it was not converting the Curl Unix exit code to a VMS
  DCL compatible exit code.  This fix required the enhancement described next.
  This also adds an enhancement to main.c so that when curl is run under a
  Unix shell like Bash on VMS, it will return the standard Unix exit codes
  and messages." And another patch for docs/examples.

  I introduced os-specific.c and os-specific.h for use in curl tool code
  and adjusted John E. Malmberg's patch placement to use these new files
  as an effort to prevent main.c from growing ad infinitum. Code already
  existing in main.c which is OS specific should be moved into these files.

Daniel Stenberg (4 June 2009)
- Setting the Content-Length: header from your app when you do a POST or PUT
  is almost always a VERY BAD IDEA. Yet there are still apps out there doing
  this, and now recently it triggered a bug/side-effect in libcurl as when
  libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
  knows it will just get a 401/407 back. If the app then replaced the
  Content-Length header, it caused the server to wait for input that libcurl
  wouldn't send. Aaron Oneal reported this problem in bug report #2799008
  (https://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix.

Yang Tse (4 Jun 2009)
- Igor Novoseltsev provided patches and information, that after some
  adjustments to better fit curl's way of doing things, have resulted
  in the posibility of building libcurl for VxWorks.

Daniel Fandrich (2 June 2009)
- Checked in a Google Android make file. To use it, you must first
  create a config.h file by running configure in the Android environment,
  which doesn't seem to be easy to do. If no easy way can be found, a
  static config-android.h may need to be created and checked in to the
  libcurl source tree.

Daniel Stenberg (1 June 2009)
- Claes Jakobsson fixed the configure script to better find and use NSS
  without pkg-config.

Yang Tse (1 Jun 2009)
- John E. Malmberg provided a VMS specific clean-up for curl.h, and pointed
  out that the configure script was failing to detect the timeval struct on
  VMS when building with _XOPEN_SOURCE_EXTENDED undefined due to definition
  taking place in socket.h instead of time.h.  I have adjusted configure
  script to also include this header when checking struct timeval.

Daniel Stenberg (27 May 2009)
- Frank McGeough provided a small OpenSSL #include fix to make libcurl compile
  fine with Nokia 5th edition 1.0 SDK for Symbian.

- Andre Guibert de Bruet found a call to a OpenSSL function that didn't check
  for a failure properly.

- Mike Crowe pointed out that setting CURLOPT_USERPWD to NULL used to clear
  the auth credentials back in 7.19.0 and earlier while now you have to set ""
  to get the same effect. His patch brings back the ability to use NULL.

- Claes Jakobsson fixed libcurl-NSS to build fine even without the
  PK11_CreateGenericObject() function.

Daniel Stenberg (25 May 2009)
- bug report #2796358 (https://curl.haxx.se/bug/view.cgi?id=2796358) pointed
  out that the cookie parser would leak memory when it parses cookies that are
  received with domain, path etc set multiple times in the same header. While
  such a cookie is questionable, they occur in the wild and libcurl no longer
  leaks memory for them. I added such a header to test case 8.

Daniel Fandrich (22 May 2009)
- Removed some obsolete digest code that caused a valgrind error in test 551.

Daniel Fandrich (20 May 2009)
- Added "non-existing host" test keywords to make it easy to skip those
  tests on machines that have broken DNS configurations (such as
  those configured to use OpenDNS).

Daniel Stenberg (19 May 2009)
- Kamil Dudka brought the patch from the Redhat bug entry
  https://bugzilla.redhat.com/show_bug.cgi?id=427966 which was libcurl closing
  a bad file descriptor when closing down the FTP data connection.  Caolan
  McNamara seems to be the original author of it.

Version 7.19.5 (18 May 2009)

Daniel Stenberg (17 May 2009)
- James Bursa posted a patch to the mailing list that fixed a problem with
  no_proxy which made it not skip the proxy if the URL entered contained a
  user name. I added test case 1101 to verify.

Daniel Stenberg (11 May 2009)
- Balint Szilakszi reported a memory leak when libcurl did gzip decompression
  of streams that had some parts (legitimately) missing. We now provide and use
  a proper cleanup function for the content encoding submodule.
  https://curl.haxx.se/mail/lib-2009-05/0092.html

- Kamil Dudka provided a fix for libcurl-NSS reported by Michael Cronenworth
  at https://bugzilla.redhat.com/show_bug.cgi?id=453612#c12

  If an incorrect password is given while loading a private key, libcurl ends
  up in an infinite loop consuming memory. The bug is critical.

- I fixed the problem with doing NTLM, POST and then following a 302 redirect,
  as reported by Ebenezer Ikonne (on curl-users) and Laurent Rabret (on
  curl-library). The transfer was mistakenly marked to get more data to send
  but since it didn't actually have that, it just hung there...

Daniel Stenberg (10 May 2009)
- Andre Guibert de Bruet correctly pointed out an over-alloc with one wasted
  byte in the digest code.

Yang Tse (9 May 2009)
- Removed DOS and TPF package's subdirectory Makefile.am, it was only used
  to include some files in the distribution tarball serving no other purpose.
  Files from the DOS and TPF subdirectories are now included in the EXTRA_DIST
  of the Makefile in the parent subdirectory.

Yang Tse (8 May 2009)
- Changed host name literal in several tests to one under the haxx.se domain.

- Renamed vc6 workspace and project files to avoid filename clash when used
  for conversion to later VS versions.

Daniel Stenberg (8 May 2009)
- Constantine Sapuntzakis fixed bug report #2784055
  (https://curl.haxx.se/bug/view.cgi?id=2784055) identifying a problem to
  connect to SOCKS proxies when using the multi interface. It turned out to
  almost not work at all previously. We need to wait for the TCP connect to
  be properly verified before doing the SOCKS magic.

  There's still a flaw in the FTP code for this.

Daniel Stenberg (7 May 2009)
- Made the SO_SNDBUF setting for the data connection socket for ftp uploads as
  well. See change 28 Apr 2009.

Yang Tse (7 May 2009)
- Fixed an issue affecting FTP transfers, introduced with the transfer.c
  patch committed May 4.

Daniel Stenberg (7 May 2009)
- Man page *roff problems fixed thanks to input from Colin Watson. Problems
  reported in the Debian package.

- Vijay G filed bug report #2723236
  (https://curl.haxx.se/bug/view.cgi?id=2723236) identifying a problem with
  libcurl's TFTP code and its lack of dealing with the OACK packet.

Yang Tse (5 May 2009)
- Fixed the --ftp-port address of test #251 to the CLIENTIP address, and
  reverted the change affecting test suite harness committed 4 May.

Daniel Stenberg (5 May 2009)
- Inspired by Michael Smith's session id fix for OpenSSL, I did the
  corresponding fix in the GnuTLS code: make sure to store the new session id
  in case the previous re-used one is rejected.

Daniel Stenberg (4 May 2009)
- Michael Smith posted bug report #2786255
  (https://curl.haxx.se/bug/view.cgi?id=2786255) with a patch, identifying how
  libcurl did not deal with SSL session ids properly if the server rejected a
  re-use of one. Starting now, it will forget the rejected one and remember
  the new. This change was for OpenSSL only, it is likely that other SSL lib
  code needs similar fixes.

Yang Tse (4 May 2009)
- Applied David McCreedy's "transfer.c fixes for CURL_DO_LINEEND_CONV and
  non-ASCII platform HTTP requests" patch addressing two HTTP PUT problems:
  1) On non-ASCII platforms not all of the protocol portions of the PUT are
  being translated to ASCII.  2) On all platforms the line endings of part of
  the protocol portions are mangled from CRLF to CRCRLF if data->set.crlf or
  data->set.prefer_ascii are set (depending on CURL_DO_LINEEND_CONV).

- Applied David McCreedy's patch to fix test suite harness to allow test FTP
  server and client on different machines, providing FTP client address when
  running the FTP test server.

Daniel Fandrich (3 May 2009)
- Added and disabled test case 563 which shows KNOWN_BUGS #59.  The bug
  report failed to mention that a proxy must be used to reproduce it.

Yang Tse (2 May 2009)
- Use a build-time configured curl_socklen_t data type instead of socklen_t.

Yang Tse (1 May 2009)
- Applied David McCreedy's patches "TPF-platform specific changes to various
  files" and "http.c fix to Curl_proxyCONNECT for non-ASCII platforms", the
  former with minor edits.

Daniel Stenberg (30 Apr 2009)
- I was going to fix issue #59 in KNOWN_BUGS

  If the CURLOPT_PORT option is used on an FTP URL like
  "ftp://example.com/file;type=A" the ";type=A" is stripped off.

  I added test case 562 to verify, only to find out that I couldn't repeat
  this bug so I hereby consider it not a bug anymore!

Daniel Stenberg (29 Apr 2009)
- Based on bug report #2723219 (https://curl.haxx.se/bug/view.cgi?id=2723219)
  I've now made TFTP "connections" not being kept for re-use within libcurl.
  TFTP is UDP-based so the benefit was really low (if even existing) to begin
  with so instead of tracking down to fix this problem we instead removed the
  re-use. I also enabled test case 1099 that I wrote a few days ago to verify
  that this change fixes the reported problem.

Daniel Stenberg (28 Apr 2009)
- Constantine Sapuntzakis filed bug report #2783090
  (https://curl.haxx.se/bug/view.cgi?id=2783090) pointing out that on windows
  we need to grow the SO_SNDBUF buffer somewhat to get really good upload
  speeds. https://support.microsoft.com/kb/823764 has the details. Friends
  confirmed that simply adding 32 to CURL_MAX_WRITE_SIZE is enough.

- Bug report #2709004 (https://curl.haxx.se/bug/view.cgi?id=2709004) by Tim
  Chen pointed out how curl couldn't upload with resume when reading from a
  pipe.

  This ended up with the introduction of a new return code for the
  CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
  that libcurl may try to resolve the situation anyway. In our case this means
  libcurl will attempt to instead read that much data from the stream instead
  of seeking and that way curl can now upload with resume when data is read
  from a stream!

Daniel Stenberg (26 Apr 2009)
- Bug report #2779733 (https://curl.haxx.se/bug/view.cgi?id=2779733) by Sven
  Wegener pointed out that CURLINFO_APPCONNECT_TIME didn't work with the multi
  interface and provided a patch that fixed the problem!

Daniel Stenberg (24 Apr 2009)
- Kamil Dudka fixed another NSS-related leak when client certs were used.

- Bug report #2779245 (https://curl.haxx.se/bug/view.cgi?id=2779245) by Rainer
  Koenig pointed out that the man page didn't tell that the *_proxy
  environment variables can be specified lower case or UPPER CASE and the
  lower case takes precedence,

Daniel Fandrich (21 Apr 2009)
- Added new libcurl source files to Amiga, RiscOS and VC6 build files.

Yang Tse (21 Apr 2009)
- Moved potential inclusion of system's malloc.h and memory.h header files to
  setup_once.h.  Inclusion of each header file is based on the definition of
  NEED_MALLOC_H and NEED_MEMORY_H respectively.

  Renamed libcurl's memory.h to curl_memory.h

Daniel Stenberg (20 Apr 2009)
- Leanic Lefever reported a crash and did some detailed research on why and
  how it occurs (https://curl.haxx.se/mail/lib-2009-04/0289.html). The
  conclusion was that if an error is detected and Curl_done() is called for
  the connection, ftp_done() could at times return another error code that
  then would take precedence and that new code confused existing logic that
  works for the first error code (CURLE_SEND_ERROR) only.

- Gisle Vanem noticed that --libtool would produce bogus strings at times for
  OBJECTPOINT options. Now we've introduced a new function - my_setopt_str -
  within the app for setting plain string options to avoid the risk of this
  mistake happening.

Daniel Stenberg (17 Apr 2009)
- Pramod Sharma reported and tracked down a bug when doing FTP over a HTTP
  proxy. libcurl would then wrongly close the connection after each
  request. In his case it had the weird side-effect that it killed NTLM auth
  for the proxy causing an inifinite loop!

  I added test case 1098 to verify this fix. The test case does however not
  properly verify that the transfers are done persistently - as I couldn't
  think of a clever way to achieve it right now - but you need to read the
  stderr output after a test run to see that it truly did the right thing.

Daniel Stenberg (13 Apr 2009)
- bug report #2727981 (https://curl.haxx.se/bug/view.cgi?id=2727981) by Martin
  Storsjö pointed out how setting CURLOPT_NOBODY to 0 could be downright
  confusing as it set the method to either GET or HEAD. The example he showed
  looked like:

   curl_easy_setopt(curl, CURLOPT_PUT, 1);
   curl_easy_setopt(curl, CURLOPT_NOBODY, 0);

  The new way doesn't alter the method until the request is about to start. If
  CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is
  0 and the request happens to have been set to HEAD, it will then instead be
  set to GET. I believe this will be less surprising to users, and hopefully
  not hit any existing users badly.

- Toshio Kuratomi reported a memory leak problem with libcurl+NSS that turned
  out to be leaking cacerts. Kamil Dudka helped me complete the fix. The issue
  is found in Redhat's bug tracker:
  https://bugzilla.redhat.com/show_bug.cgi?id=453612

  There are still memory leaks present, but they seem to have other reasons.

Daniel Fandrich (11 Apr 2009)
- Added new libcurl source files to Symbian OS build files.
- Improved Symbian support for SSL.

Yang Tse (10 Apr 2009)
- Daniel Johnson improved the MacOSX-Framework shell script to now perform all
  the steps required to build a Mac OS X four way fat ppc/i386/ppc64/x86_64
  libcurl.framework.  Four way fat framework requires OS X 10.5 SDK or later.

Yang Tse (8 Apr 2009)
- Removed Sun compilers preprocessor block from curlbuild.h.dist, this also
  removes it from the curlbuild.h file originally distributed by the cURL
  project as this file is intended for systems not capable of running the
  configure script.  For those who have been building curl out of the source
  code curl distribution tarball provided by curl.haxx.se the change implies
  nothing.  Previous change in this area committed 2 Apr becomes irrelevant.

Daniel Stenberg (6 Apr 2009)
- I clarified in the docs that CURLOPT_SEEKFUNCTION should return 0 on success
  and 1 on fatal errors. Previously it only mentioned non-zero on fatal
  errors. This is a slight change in meaning, but it follows what we've done
  elsewhere before and it opens up for LOTS of more useful return codes
  whenever we can think of them...

Yang Tse (2 Apr 2009)
- Fix curl_off_t definition for builds done using Sun compilers and a
  non-configured libcurl. In this case curl_off_t data type was gated
  to the off_t data type which depends on the _FILE_OFFSET_BITS. This
  configuration is exactly the unwanted configuration for our curl_off_t
  data type which must not depend on such setting. This breaks ABI for
  libcurl libraries built with Sun compilers which were built without
  having run the configure script with _FILE_OFFSET_BITS different than
  64 and using the ILP32 data model.

Daniel Stenberg (1 Apr 2009)
- Andre Guibert de Bruet fixed a NULL pointer use in an infof() call if a
  strdup() call failed.

Daniel Fandrich (31 Mar 2009)
- Properly return an error code in curl_easy_recv (reported by Jim Freeman).

Daniel Stenberg (18 Mar 2009)
- Kamil Dudka brought a patch that enables 6 additional crypto algorithms when
  NSS is used. These ciphers were added in NSS 3.4 and require to be enabled
  explicitly.

Daniel Stenberg (13 Mar 2009)
- Use libssh2_version() to present the libssh2 version in case the libssh2
  library is found to support it.

Yang Tse (12 Mar 2009)
- Added missing Curl_read() return code checking in TELNET transfers.

- Pierre Brico found and fixed TELNET transfers not being aborted upon
  a write callback failure.

Daniel Stenberg (11 Mar 2009)
- Kamil Dudka made the curl tool properly call curl_global_init() before any
  other libcurl function.

Yang Tse (11 Mar 2009)
- Added missing TELNET timeout support for Windows builds. This issue was
  reported by Pierre Brico.

Daniel Stenberg (9 Mar 2009)
- Frank Hempel found out a bug and provided the fix:

  curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE
  option. It only enabled the cookie engine in the destination handle if
  data->cookies is not NULL (where data is the source handle). In case of a
  newly initialized handle which just had the cookie support enabled by a
  curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was
  still NULL because the setopt-call only appends the value to
  data->change.cookielist, hence duplicating this handle would not have the
  cookie engine switched on.

  We also concluded that the slist-functionality would be suitable for being
  put in its own module rather than simply hanging out in lib/sendf.c so I
  created lib/slist.[ch] for them.

- Andreas Farber made the 'buildconf' script check for the presence of m4
  scripts to make it detect a bad checkout earlier. People with older
  checkouts who don't do cvs update with the -d option won't get the new dirs
  and then will get funny outputs that can be a bit hard to understand and
  fix.

Daniel Stenberg (8 Mar 2009)
- Andre Guibert de Bruet found and fixed a code segment in ssluse.c where the
  allocation of the memory BIO was not being properly checked.

- Andre Guibert de Bruet fixed the gnutls-using code: There are a few places
  in the gnutls code where we were checking for negative values for errors,
  when the man pages state that GNUTLS_E_SUCCESS is returned on success and
  other values indicate error conditions.

- Bill Egert pointed out (https://curl.haxx.se/bug/view.cgi?id=2671602) that
  curl didn't use sprintf() in a way that is documented to work in POSIX but
  since we use our own printf() code (from libcurl) that shouldn't be a
  problem. Nonetheless I modified the code to not rely on such particular
  features and to not cause further raised eyebrowse with no good reason.

Daniel Fandrich (5 Mar 2009)
- Expanded the security section of the libcurl-tutorial man page to cover
  more issues for authors to consider when writing robust libcurl-using
  applications.

Yang Tse (5 Mar 2009)
- Fixed NTLM authentication memory leak on SSPI enabled Windows builds. This
  issue was noticed by Chris Deidun.

Daniel Fandrich (4 Mar 2009)
- Fixed a problem with m4 quoting in the OpenSSL configure check reported
  by Daniel Johnson.

Daniel Stenberg (3 Mar 2009)
- David James brought a patch that make libcurl close (all) dead connections
  whenever you attempt to open a new connection.

  1. After cleaning up a dead connection, "continue" instead of
     returning FALSE. This ensures that we clean up all dead connections,
     rather than just cleaning up the first dead connection.
  2. Move up the cleanup for dead connections so that it occurs for
     all connections, rather than just the connections which have the same
     preferences as our current new connection.

Version 7.19.4 (3 March 2009)

Daniel Stenberg (3 Mar 2009)
- David Kierznowski notified us about a security flaw
  (https://curl.haxx.se/docs/adv_20090303.html also known as CVE-2009-0037) in
  which previous libcurl versions (by design) can be tricked to access an
  arbitrary local/different file instead of a remote one when
  CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
  together this the addition of two new setopt options for controlling this
  new behavior:

  o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
  follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
  excludes the FILE and SCP protocols and thus you nee to explicitly allow
  them in your app if you really want that behavior.

  o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
  using the primary URL option. This is useful if you want to allow a user or
  other outsiders control what URL to pass to libcurl and yet not allow all
  protocols libcurl may have been built to support.

Daniel Stenberg (27 Feb 2009)
- Senthil Raja Velu reported a problem when CURLOPT_INTERFACE and
  CURLOPT_LOCALPORT were used together (the local port bind failed), and
  Markus Koetter provided the fix!

Daniel Stenberg (25 Feb 2009)
- As Daniel Fandrich figured out, we must do the GnuTLS initing in the
  curl_global_init() function to properly maintain the performing functions
  thread-safe. We've previously (28 April 2007) moved the init to a later time
  just to avoid it to fail very early when libgcrypt dislikes the situation,
  but that move was bad and the fix should rather be in libgcrypt or
  elsewhere.

Daniel Stenberg (24 Feb 2009)
- Brian J. Murrell found out that Negotiate proxy authentication didn't work.
  It happened because the code used the struct for server-based auth all the
  time for both proxy and server auth which of course was wrong.

Daniel Stenberg (23 Feb 2009)
- After a bug reported by James Cheng I've made curl_easy_getinfo() for
  CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return
  -1 if the sizes aren't know. Previously these returned 0, make it impossible
  to detect the difference between actually zero and unknown.

Yang Tse (23 Feb 2009)
- Daniel Johnson provided a shell script that will perform all the steps needed
  to build a Mac OS X fat ppc/i386 or ppc64/x86_64 libcurl.framework

Daniel Stenberg (23 Feb 2009)
- I renamed everything in the windows builds files that used the name 'curllib'
  to the proper 'libcurl' as clearly this caused confusion.

Yang Tse (20 Feb 2009)
- Do not halt compilation when using VS2008 to build a Windows 2000 target.

Daniel Stenberg (20 Feb 2009)
- Linus Nielsen Feltzing reported and helped me repeat and fix a problem with
  FTP with the multi interface: when a transfer fails, like when aborted by a
  write callback, the control connection was wrongly closed and thus not
  re-used properly.

  This change is also an attempt to cleanup the code somewhat in this area, as
  now the FTP code attempts to keep (better) track on pending responses
  necessary to get read in ftp_done().

Daniel Stenberg (19 Feb 2009)
- Patrik Thunstrom reported a problem and helped me repeat it. It turned out
  libcurl did a superfluous 1000ms wait when doing SFTP downloads!

  We read data with libssh2 while doing the "DO" operation for SFTP and then
  when we were about to start getting data for the actual file part, the
  "TRANSFER" part, we waited for socket action (in 1000ms) before doing a
  libssh2-read. But in this case libssh2 had already read and buffered the
  data so we ended up always just waiting 1000ms before we get working on the
  data!

Patrick Monnerat (18 Feb 2009)
- FTP downloads (i.e.: RETR) ending with code 550 now return error
  CURLE_REMOTE_FILE_NOT_FOUND instead of CURLE_FTP_COULDNT_RETR_FILE.

Daniel Stenberg (17 Feb 2009)
- Kamil Dudka made NSS-powered builds compile and run again!

- A second follow-up change by Andre Guibert de Bruet to fix a related memory
  leak like that fixed on the 14th. When zlib returns failure, we need to
  cleanup properly before returning error.

- CURLOPT_FTP_CREATE_MISSING_DIRS can now be set to 2 in addition to 1 for
  plain FTP connections, and it will then allow MKD to fail once and retry the
  CWD afterwards. This is especially useful if you're doing many simultanoes
  connections against the same server and they all have this option enabled,
  as then CWD may first fail but then another connection does MKD before this
  connection and thus MKD fails but trying CWD works! The numbers can
  (should?) now be set with the convenience enums now called
  CURLFTP_CREATE_DIR and CURLFTP_CREATE_DIR_RETRY.

  Tests has proven that if you're making an application that uploads a set of
  files to an ftp server, you will get a noticable gain in speed if you're
  using multiple connections and this option will be then be very useful.

Daniel Stenberg (14 Feb 2009)
- Andre Guibert de Bruet found and fixed a memory leak in the content encoding
  code, which could happen on libz errors.

Daniel Fandrich (12 Feb 2009)
- Added support for Digest and NTLM authentication using GnuTLS.

Daniel Stenberg (11 Feb 2009)
- CURLINFO_CONDITION_UNMET was added to allow an application to get to know if
  the condition in the previous request was unmet. This is typically a time
  condition set with CURLOPT_TIMECONDITION and was previously not possible to
  reliably figure out. From bug report #2565128
  (https://curl.haxx.se/bug/view.cgi?id=2565128) filed by Jocelyn Jaubert.

Daniel Fandrich (4 Feb 2009)
- Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS
  (respectively) when --with-ssl=/usr is used (patch based on FreeBSD).

- Added an explicit buffer limit check in msdosify() (patch based on FreeBSD).
  This couldn't ever overflow in curl, but might if the code were used
  elsewhere or under different conditions.

Daniel Stenberg (3 Feb 2009)
- Hidemoto Nakada provided a small fix that makes it possible to get the
  CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with
  CURLOPT_NOBODY set true.

Daniel Stenberg (2 Feb 2009)
- Patrick Scott found a rather large memory leak when using the multi
  interface and setting CURLMOPT_MAXCONNECTS to something less than the number
  of handles you add to the multi handle. All the connections that didn't fit
  in the cache would not be properly disconnected nor freed!

- Craig A West brought us: libcurl now defaults to do CONNECT with HTTP
  version 1.1 instead of 1.0 like before. This change also introduces the new
  proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
  switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
  option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.

  I updated all test cases cases that use CONNECT and I tried to do some using
  --proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.

Daniel Stenberg (31 Jan 2009)
- When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
  enabled, we can now take advantage of its brand new AF_UNSPEC support in
  ares_gethostbyname(). This makes test case 241 finally run fine for me with
  this setup since it now parses the "::1 ip6-localhost" line fine in my
  /etc/hosts file!

Daniel Stenberg (30 Jan 2009)
- Scott Cantor filed bug report #2550061
  (https://curl.haxx.se/bug/view.cgi?id=2550061) mentioning that I failed to
  properly make sure that the VC9 makefiles got included in the latest
  release. I've now fixed the release script and verified it so next release
  will hopefully include them properly!

Daniel Fandrich (30 Jan 2009)
- Fixed --disable-proxy for FTP and SOCKS. Thanks to Daniel Egger for
  reporting.

Yang Tse (29 Jan 2009)
- Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
  Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
  named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
  Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
  SSPI library using it now in the same way as it was done in http_ntlm.c.

Daniel Stenberg (28 Jan 2009)
- Markus Moeller introduced two new options to libcurl:
  CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl
  to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
  options called --socks5-gssapi-service and --socks5-gssapi-nec to enable
  these.

Daniel Stenberg (26 Jan 2009)
- Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app
  to set desired block size to use for TFTP transfers instead of the default
  512 bytes.

- The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
  disable "rfc4507bis session ticket support".  rfc4507bis was later turned
  into the proper RFC5077 it seems: http://tools.ietf.org/html/rfc5077

  The enabled extension concerns the session management. I wonder how often
  libcurl stops a connection and then resumes a TLS session. also, sending the
  session data is some overhead. .I suggest that you just use your proposed
  patch (which explicitly disables TICKET).

  If someone writes an application with libcurl and openssl who wants to
  enable the feature, one can do this in the SSL callback.

  Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
  on the proper action.

- Alexey Borzov filed bug report #2535504
  (https://curl.haxx.se/bug/view.cgi?id=2535504) pointing out that realms with
  quoted quotation marks in HTTP Digest headers didn't work. I've now added
  test case 1095 that verifies my fix.

- Craig A West brought CURLOPT_NOPROXY and the corresponding --noproxy option.
  They basically offer the same thing the NO_PROXY environment variable only
  offered previously: list a set of host names that shall not use the proxy
  even if one is specified.

Daniel Fandrich (20 Jan 2009)
- Call setlocale() for libtest tests to test the effects of locale-induced
  libc changes on libcurl.

- Fixed a couple more locale-dependent toupper conversions, mainly for
  clarity.  This does fix one problem that causes ;type=i FTP URLs
  to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
  used (test case 561)

- Added tests 561 and 1091 through 1094 to test various combinations
  of ;type= and ;mode= URLs that could potentially fail in the Turkish
  locale.

Daniel Stenberg (20 Jan 2009)
- Lisa Xu pointed out that the ssh.obj file was missing from the
  lib/Makefile.vc6 file (and thus from the vc8 and vc9 ones too).

Version 7.19.3 (19 January 2009)

Daniel Stenberg (16 Jan 2009)
- Andrew de los Reyes fixed curlbuild.h for "generic" gcc builds on PPC, both
  32 bit and 64 bit.

Daniel Stenberg (15 Jan 2009)
- Tim Ansell fixed a compiler warning in lib/cookie.c

Daniel Stenberg (14 Jan 2009)
- Grant Erickson fixed timeouts for TFTP such that specifying a
  connect-timeout, a max-time or both options work correctly and as expected
  by passing the correct boolean value to Curl_timeleft via the
  'duringconnect' parameter.

  With this small change, curl TFTP now behaves as expected (and likely as
  originally-designed):

  1) For non-existent or unreachable dotted IP addresses:

   a) With no options, follows the default curl 300s timeout...
   b) With --connect-timeout only, follows that value...
   c) With --max-time only, follows that value...
   d) With both --connect-timeout and --max-time, follows the smaller value...

   and times out with a "curl: (7) Couldn't connect to server" error.

  2) For transfers to/from a valid host:

   a) With no options, follows default curl 300s timeout for the
      first XRQ/DATA/ACK transaction and the default TFTP 3600s
      timeout for the remainder of the transfer...

   b) With --connect-time only, follows that value for the
      first XRQ/DATA/ACK transaction and the default TFTP 3600s
      timeout for the remainder of the transfer...

   c) With --max-time only, follows that value for the first
      XRQ/DATA/ACK transaction and for the remainder of the
      transfer...

   d) With both --connect-timeout and --max-time, follows the former
      for the first XRQ/DATA/ACK transaction and the latter for the
      remainder of the transfer...

   and times out with a "curl: (28) Timeout was reached" error as
   appropriate.

Daniel Stenberg (13 Jan 2009)
- Michael Wallner fixed a NULL pointer deref when calling
  curl_easy_setup(curl, CURLOPT_COOKIELIST, "SESS") on a CURL handle with no
  cookies data.

- Stefan Teleman brought a patch to fix the default curlbuild.h file for the
  SunPro compilers.

Daniel Stenberg (12 Jan 2009)
- Based on bug report #2498665 (https://curl.haxx.se/bug/view.cgi?id=2498665)
  by Daniel Black, I've now added magic to the configure script that makes it
  use pkg-config to detect gnutls details as well if the existing method
  (using libgnutls-config) fails. While doing this, I cleaned up and unified
  the pkg-config usage when detecting openssl and nss as well.

Daniel Stenberg (11 Jan 2009)
- Karl Moerder brought the patch that creates vc9 Makefiles, and I made
  'maketgz' now use the actual makefile targets to do the VC8 and VC9
  makefiles.

Daniel Stenberg (10 Jan 2009)
- Emil Romanus fixed:

  When using the multi interface over HTTP and the server returns a Location
  header, the running easy handle will get stuck in the CURLM_STATE_PERFORM
  state, leaving the external event loop stuck waiting for data from the
  ingoing socket (when using the curl_multi_socket_action stuff). While this
  bug was pretty hard to find, it seems to require only a one-line fix. The
  break statement on line 1374 in multi.c caused the function to skip the call
  to multistate().

  How to reproduce this bug? Well, that's another question.  evhiperfifo.c in
  the examples directory chokes on this bug only _sometimes_, probably
  depending on how fast the URLs are added. One way of testing the bug out is
  writing to hiper.fifo from more than one source at the same time.

Daniel Fandrich (7 Jan 2009)
- Unified much of the SessionHandle initialization done in Curl_open() and
  curl_easy_reset() by creating Curl_init_userdefined(). This had the side
  effect of fixing curl_easy_reset() so it now also resets
  CURLOPT_FTP_FILEMETHOD and CURLOPT_SSL_SESSIONID_CACHE

Daniel Stenberg (7 Jan 2009)
- Rob Crittenden did once again provide an NSS update:

  I have to jump through a few hoops now with the NSS library initialization
  since another part of an application may have already initialized NSS by the
  time Curl gets invoked. This patch is more careful to only shutdown the NSS
  library if Curl did the initialization.

  It also adds in a bit of code to set the default ciphers if the app that
  call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
  ciphers. One might argue that this lets other application developers get
  lazy and/or they aren't using the NSS API correctly, and you'd be right.
  But still, this will avoid terribly difficult-to-trace crashes and is
  generally helpful.

Daniel Stenberg (1 Jan 2009)
- 'reconf' is removed since we rather have users use 'buildconf'

Daniel Stenberg (31 Dec 2008)
- Bas Mevissen reported https://curl.haxx.se/bug/view.cgi?id=2479030 pointing
  out that 'reconf' didn't properly point out the m4 subdirectory when running
  aclocal.

Daniel Stenberg (29 Dec 2008)
 - Phil Lisiecki filed bug report #2413067
  (https://curl.haxx.se/bug/view.cgi?id=2413067) that identified a problem that
  would cause libcurl to mark a DNS cache entry "in use" eternally if the
  subsequence TCP connect failed. It would thus never get pruned and refreshed
  as it should've been.

  Phil provided his own patch to this problem that while it seemed to work
  wasn't complete and thus I wrote my own fix to the problem.

Daniel Stenberg (28 Dec 2008)
- Peter Korsgaard fixed building libcurl with "configure --with-ssl
  --disable-verbose".

- Anthony Bryan fixed more language and spelling flaws in man pages.

Daniel Stenberg (22 Dec 2008)
- Given a recent enough libssh2, libcurl can now seek/resume with SFTP even
  on file indexes beyond 2 or 4GB.

- Anthony Bryan provided a set of patches that cleaned up manual language,
  corrected spellings and more.

Daniel Stenberg (20 Dec 2008)
- Igor Novoseltsev fixed a bad situation for the multi_socket() API when doing
  pipelining, as libcurl could then easily get confused and A) work on the
  handle that was not "first in queue" on a pipeline, or even B) tell the app
  to REMOVE a socket while it was in use by a second handle in a pipeline. Both
  errors caused hanging or stalling applications.

Daniel Stenberg (19 Dec 2008)
- curl_multi_timeout() could return a timeout value of 0 even though nothing
  was actually ready to get done, as the internal time resolution is higher
  than the returned millisecond timer. Therefore it could cause applications
  running on fast processors to do short bursts of busy-loops.
  curl_multi_timeout() will now only return 0 if the timeout is actually
  alreay triggered.

- Using the libssh2 0.19 function libssh2_session_block_directions(), libcurl
  now has an improved ability to do right when the multi interface (both
  "regular" and multi_socket) is used for SCP and SFTP transfers. This should
  result in (much) less busy-loop situations and thus less CPU usage with no
  speed loss.

Daniel Stenberg (17 Dec 2008)
- SCP and SFTP with the multi interface had the same flaw: the 'DONE'
  operation didn't complete properly if the EAGAIN equivalent was returned but
  libcurl would simply continue with a half-completed close operation
  performed. This ruined persistent connection re-use and cause some
  SSH-protocol errors in general. The correction is unfortunately adding a
  blocking function - doing it entirely non-blocking should be considered for
  a better fix.

Gisle Vanem (16 Dec 2008)
- Added the possibility to use the Watt-32 tcp/ip stack under Windows.
  The change simply involved adding a USE_WATT32 section in the
  config-win32.h files (under ./lib and ./src). This section disables
  the use of any Winsock headers.

Daniel Stenberg (16 Dec 2008)
- libssh2_sftp_last_error() was wrongly used at some places in libcurl which
  made libcurl sometimes not properly abort problematic SFTP transfers.

Daniel Stenberg (12 Dec 2008)
- More work with Igor Novoseltsev to first fix the remaining stuff for
  removing easy handles from multi handles when the easy handle is/was within
  a HTTP pipeline. His bug report #2351653
  (https://curl.haxx.se/bug/view.cgi?id=2351653) was also related and was
  eventually fixed by a patch by Igor himself.

Yang Tse (12 Dec 2008)
- Patrick Monnerat fixed a build regression, introduced in 7.19.2, affecting
  OS/400 compilations with IPv6 enabled.

Daniel Stenberg (12 Dec 2008)
- Mark Karpeles filed bug report #2416182 titled "crash in ConnectionExists
  when using duphandle+curl_mutli"
  (https://curl.haxx.se/bug/view.cgi?id=2416182) which showed that
  curl_easy_duphandle() wrongly also copied the pointer to the connection
  cache, which was plain wrong and caused a segfault if the handle would be
  used in a different multi handle than the handle it was duplicated from.

Daniel Stenberg (11 Dec 2008)
- Keshav Krity found out that libcurl failed to deal with dotted IPv6
  addresses if they were very long (>39 letters) due to a too strict address
  validity parser. It now accepts addresses up to 45 bytes long.

Daniel Stenberg (11 Dec 2008)
- Internet Explorer had a broken HTTP digest authentication before v7 and
  there are servers "out there" that relies on the client doing this broken
  Digest authentication. Apache even comes with an option to work with such
  broken clients.

  The difference is only for URLs that contain a query-part (a '?'-letter and
  text to the right of it).

  libcurl now supports this quirk, and you enable it by setting the
  CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or
  CURLOPT_PROXYAUTH options. They are thus individually controlled to server
  and proxy.

  (note that there's no way to activate this with the curl tool yet)

Daniel Fandrich (9 Dec 2008)
- Added test cases 1089 and 1090 to test --write-out after a redirect to
  test a report that the size didn't work, but these test cases pass.

- Documented CURLOPT_CONNECT_ONLY as being useful only on HTTP URLs.

Daniel Stenberg (9 Dec 2008)
- Ken Hirsch simplified how libcurl does FTPS: now it doesn't assume any
  particular state for the control connection like it did before for implicit
  FTPS (libcurl assumed such control connections to be encrypted while some
  FTPS servers such as FileZilla assumes such connections to be clear
  mode). Use the CURLOPT_USE_SSL option to set your desired level.

Daniel Stenberg (8 Dec 2008)
- Fred Machado posted about a weird FTP problem on the curl-users list and when
  researching it, it turned out he got a 550 response back from a SIZE command
  and then I fell over the text in RFC3659 that says:

   The presence of the 550 error response to a SIZE command MUST NOT be taken
   by the client as an indication that the file cannot be transferred in the
   current MODE and TYPE.

  In other words: the change I did on September 30th 2008 and that has been
  included in the last two releases were a regression and a bad idea. We MUST
  NOT take a 550 response from SIZE as a hint that the file doesn't exist.

- Christian Krause filed bug #2221237
  (https://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite
  loop during GSS authentication given some specific conditions. With his
  patience and great feedback I managed to narrow down the problem and
  eventually fix it although I can't test any of this myself!

Daniel Fandrich (3 Dec 2008)
- Fixed the getifaddrs version of Curl_if2ip to work on systems without IPv6
  support (e.g. Minix)

Daniel Stenberg (3 Dec 2008)
- Igor Novoseltsev filed bug #2351645
  (https://curl.haxx.se/bug/view.cgi?id=2351645) that identified a problem with
  the multi interface that occured if you removed an easy handle while in
  progress and the handle was used in a HTTP pipeline.

- Pawel Kierski pointed out a mistake in the cookie code that could lead to a
  bad fclose() after a fatal error had occured.
  (https://curl.haxx.se/bug/view.cgi?id=2382219)

Daniel Fandrich (25 Nov 2008)
- If a HTTP request is Basic and num is already >=1000, the HTTP test
  server adds 1 to num to get the data section to return. This allows
  testing authentication negotiations using the Basic authentication
  method.

- Added tests 1087 and 1088 to test Basic authentication on a redirect
  with and without --location-trusted

Daniel Stenberg (24 Nov 2008)
- Based on a patch by Vlad Grachov, libcurl now uses a new libssh2 0.19
  function when built to support SCP and SFTP that helps the library to know
  in which direction a particular libssh2 operation would return EAGAIN so
  that libcurl knows what socket conditions to wait for before trying the
  function call again. Previously (and still when using libssh2 0.18 or
  earlier), libcurl will busy-loop in this situation when the easy interface
  is used!

Daniel Fandrich (20 Nov 2008)
- Automatically detect OpenBSD's CA cert bundle.

Daniel Stenberg (19 Nov 2008)
- I removed the default use of "Pragma: no-cache" from libcurl when a proxy is
  used. It has been used since forever but it was never a good idea to use
  unless explicitly asked for.

- Josef Wolf's extension that allows a $TESTDIR/gdbinit$testnum file that when
  you use runtests.pl -g, will be sourced by gdb to allow additional fancy or
  whatever you see fit

- Christian Krause reported and fixed a memory leak that would occur with HTTP
  GSS/kerberos authentication (https://curl.haxx.se/bug/view.cgi?id=2284386)

- Andreas Wurf and Markus Koetter helped me analyze a problem that Andreas got
  when uploading files to a single FTP server using multiple easy handle
  handles with the multi interface. Occasionally a handle would stall in
  mysterious ways.

  The problem turned out to be a side-effect of the ConnectionExists()
  function's eagerness to re-use a handle for HTTP pipelining so it would
  select it even if already being in use, due to an inadequate check for its
  chances of being used for pipelnining.

Daniel Fandrich (17 Nov 2008)
- Added more compiler warning options for gcc 4.3

Yang Tse (17 Nov 2008)
- Fix a remaining problem in the inet_pton() runtime configure check. And
  fix internal Curl_inet_pton() failures to reject certain malformed literals.

- Make configure script check if ioctl with the SIOCGIFADDR command can be
  used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate.

Daniel Stenberg (16 Nov 2008)
- Christian Krause fixed a build failure when building with gss support
  enabled and FTP disabled.

- Added check for NULL returns from strdup() in src/main.c and lib/formdata.c
  - reported by Jim Meyering also prevent buffer overflow on MSDOS when you do
  for example -O on a url with a file name part longer than PATH_MAX letters

- lib/nss.c fixes based on the report by Jim Meyering: I went over and added
  checks for return codes for all calls to malloc and strdup that were
  missing. I also changed a few malloc(13) to use arrays on the stack and a
  few malloc(PATH_MAX) to instead use aprintf() to lower memory use.

- I fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is
  in use.

Daniel Fandrich (14 Nov 2008)
- Added .xml as one of the few common file extensions known by the multipart
  form generator.

- Added some #ifdefs around header files and change the EAGAIN test to
  fix compilation on Cell (reported by Jeff Curley).

Yang Tse (14 Nov 2008)
- Fixed several configure script issues affecting checks for inet_ntoa_r(),
  inet_ntop(), inet_pton(), getifaddrs(), fcntl() and getaddrinfo().

Yang Tse (13 Nov 2008)
- Refactored configure script detection of functions used to set sockets into
  non-blocking mode, and decouple function detection from function capability.

Version 7.19.2 (13 November 2008)

Michal Marek (13 Nov 2008)
- Fixed a potential data loss in Curl_client_write() when the transfer is
  paused.

Daniel Stenberg (11 Nov 2008)
- Rainer Canavan filed bug #2255627
  (https://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a
  program using libcurl's multi interface to download a HTTPS page with a
  libcurl built powered by OpenSSL, would easily get silly and instead hand
  over SSL details as data instead of the actual HTTP headers and body. This
  happened because libcurl would consider the connection handshake done too
  early. This problem was introduced at September 22nd 2008 with my fix of the
  bug #2107377

  The correct fix is now instead done within the GnuTLS-handling code, as both
  the OpenSSL and the NSS code already deal with this situation in similar
  fashion. I added test case 560 in an attempt to verify this fix, but
  unfortunately it didn't trigger it even before this fix!

Yang Tse (11 Nov 2008)
- Related with bug #2230535 (https://curl.haxx.se/bug/view.cgi?id=2230535)
  Daniel Fandrich noticed that curl_addrinfo was also missing in the build
  process of other four non-configure platforms. Added now.

Daniel Fandrich (7 Nov 2008)
- The getifaddrs() version of Curl_if2ip() crashed when used on a Linux
  system with a TEQL load-balancing device configured, which doesn't
  have an address.  Thanks to Adam Sampson for spotting this (bug #2234923).

Yang Tse (6 Nov 2008)
- Merged existing IPv4 and IPv6 Curl_ip2addr functions into a single one
  which now also takes a protocol address family argument.

- Bug #2230535 (https://curl.haxx.se/bug/view.cgi?id=2230535) pointed out a
  problem with MSVC 6 makefile that caused a build failure. It was noted that
  the curl_addrinfo.obj reference was missing. I took the opportunity to sort
  the list in which this was missing. Issue submitted by John Wilkinson.

Version 7.19.1 (5 November 2008)

Daniel Stenberg (4 Nov 2008)
- CURLINFO_FILETIME now works for file:// transfers as well

Daniel Stenberg (3 Nov 2008)
- Bug #2218480 (https://curl.haxx.se/bug/view.cgi?id=2218480) pointed out a
  problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
  pointer read. I also took the opportunity to clean up this logic (storing of
  the connection's IP address) somewhat as we had it stored in two different
  places and ways previously and they are now unified.

Yang Tse (3 Nov 2008)
- Fix undersized IPv6 address internal buffer. IPv6 address strings longer
  than 35 characters would be truncated.

Daniel Stenberg (2 Nov 2008)
- Daniel Johnson reported and fixed:

  When c-ares isn't enabled, libcurl by default calls getaddrinfo with family
  set to PF_UNSPEC which causes getaddrinfo to return all available addresses,
  both IPv4 and IPv6. Libcurl then tries each one until it can connect. If the
  net connection doesn't support IPv6, libcurl can still fall back to IPv4.

  However, since c-ares doesn't support PF_UNSPEC, when it's used it defaults
  to using family=PF_INET6 and therefore only returns IPv6 addresses when AAAA
  records are available, even if IPv4 addresses are also available. The effect
  is that since my ISP doesn't do IPv6, libcurl can't connect at all to a site
  that has AAAA records. It will work if I explicitly use CURL_IPRESOLVE_V4 or
  --ipv4 with the curl tool. I discovered this when curl would fail to connect
  to seemingly random sites. It turns out they weren't random, they were sites
  with AAAA records.

  So now libcurl defaults to PF_INET... until c-ares has been tought to offer
  both.

Yang Tse (31 Oct 2008)
- Tests 558 and 559 are stabilized. These two tests were initially introduced
  to aid in the location of a seg-fault which was only triggered on non-debug
  builds done with the icc 9.1 Intel compiler. Test 558 does not trigger the
  problem, but test 559 does trigger it. As of today, it isn't yet absolutely
  clear if it is a compiler optimizer issue or a memory corruption one.

Yang Tse (30 Oct 2008)
- Use our Curl_addrinfo structure definition to handle address info data even
  when a system addrinfo struct is available. Provide and use a wrapper around
  systems getaddrinfo function, Curl_getaddrinfo_ex which returns a pointer to
  a list of dynamically allocated Curl_addrinfo structs.

  Configure will check freeaddrinfo and getaddrinfo functions and define
  preprocessor symbols HAVE_FREEADDRINFO and HAVE_GETADDRINFO when appropriate.

Daniel Fandrich (29 Oct 2008)
- Fixed a bug that caused a few bytes of garbage to be sent after a
  curl_easy_pause() during a chunky upload. Reported by Steve Roskowski.

Daniel Fandrich (28 Oct 2008)
- Changed the "resolve" test precheck program to verify that an IPv6 socket
  can be created before resolving the IPv6 name.  In the context of running
  a test, it doesn't make sense to run an IPv6 test when a host is resolvable
  but IPv6 isn't usable.  This should fix failures of test 1085 on hosts with
  library and DNS support for IPv6 but where actual use of IPv6 has been
  administratively disabled.

Daniel Fandrich (24 Oct 2008)
- Added experimental support for zlib and OpenSSL on Symbian OS.

Daniel Fandrich (21 Oct 2008)
- Fixed some problems with SFTP range support to fix test cases 634 through
  637.

Daniel Fandrich (17 Oct 2008)
- Fixed a compile error reported by Albert Chin on AIX and IRIX when using
  GTLS.

Daniel Stenberg (16 Oct 2008)
- Igor Novoseltsev added CURLOPT_PROXYUSER and CURLOPT_PROXYPASSWORD that then
  make CURLOPT_PROXYUSERPWD sort of deprecated. The primary motive for adding
  these new options is that they have no problems with the colon separator
  that the CURLOPT_PROXYUSERPWD option does.

Daniel Stenberg (15 Oct 2008)
- Pascal Terjan filed bug #2154627
  (https://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl
  uses strcasecmp() in multiple places where it causes failures when the
  Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
  strcasecmp() on those letters are different in Turkish than in English (or
  just about all other languages). I thus introduced a totally new internal
  function in libcurl (called Curl_raw_equal) for doing case insentive
  comparisons for english-(ascii?) style strings that thus will make "file"
  and "FILE" match even if the Turkish locale is selected.

Daniel Fandrich (15 Oct 2008)
- A <precheck> command is considered to have failed if it returns a non-zero
  return code.  This way, if the precheck command can't be run at all for
  whatever reason, it's treated as a precheck failure which causes the
  test to be skipped.

Daniel Stenberg (15 Oct 2008)
- John Wilkinson filed bug #2155496
  (https://curl.haxx.se/bug/view.cgi?id=2155496) pointing out an error case
  without a proper human-readable error message. When a read callback returns
  a too large value (like when trying to return a negative number) it would
  trigger and the generic error message then makes the proplem slightly
  different to track down. I've added an error message for this now.

Daniel Fandrich (9 Oct 2008)
- Fixed the --interface option to work with IPv6 connections on glibc
  systems supporting getifaddrs(). Also fixed a problem where an IPv6
  address could be chosen instead of an IPv4 one for --interface when it
  involved a name lookup.

Daniel Fandrich (8 Oct 2008)
- Added tests 1082 through 1085 to test symbolic --interface parameters

- Added tests 633 through 637 to test the new file range support for SFTP.
  All but the first test cause an infinite loop or other failure and so
  are added to DISABLED.

Daniel Stenberg (8 Oct 2008)
- John Wilkinson filed bug #2152270
  (https://curl.haxx.se/bug/view.cgi?id=2152270) which identified and fixed a
  CURLINFO_REDIRECT_URL memory leak and an additional wrong-doing:

  Any subsequent transfer with a redirect leaks memory, eventually crashing
  the process potentially.

  Any subsequent transfer WITHOUT a redirect causes the most recent redirect
  that DID occur on some previous transfer to still be reported.

- Igor Novoseltsev filed bug #2111613
  (https://curl.haxx.se/bug/view.cgi?id=2111613) that eventually identified a
  flaw in how the multi_socket interface in some cases missed to call the
  timeout callback when easy interfaces are removed and added within the same
  millisecond.

- Igor Novoseltsev brought a patch that introduced two new options to
  curl_easy_setopt: CURLOPT_USERNAME and CURLOPT_PASSWORD that sort of
  deprecates the good old CURLOPT_USERPWD since they allow applications to set
  the user name and password independently and perhaps more importantly allow
  both to contain colon(s) which CURLOPT_USERPWD doesn't fully support.

Daniel Fandrich (7 Oct 2008)
- Changed the handling of read/write errors in Curl_perform() to allow a
  a fresh connection to be made in such cases and the request retransmitted.
  This should fix test case 160.  Added test case 1079 in an attempt to
  test a similar connection dropping scenario, but as a race condition, it's
  hard to test reliably.

- Created test cases 1080 and 1081 to reproduce a problem of
  CURLINFO_REDIRECT_URL leaking memory and returning incorrect results when
  two URLs are requested. Reported by vmpdemo in bug #2152270

Daniel Stenberg (7 Oct 2008)
- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then
  the app re-used the handle to do a connection to host B and then again
  re-used the handle to host A, it would not update the info with host A's IP
  address (due to the connection being re-used) but it would instead report
  the info from host B.

Yang Tse (7 Oct 2008)
- Added --enable-optimize configure option to enable and disable compiler
  optimizations to allow decoupled setting from --enable-debug.

Yang Tse (2 Oct 2008)
- Added --enable-warnings configure option to enable and disable strict
  compiler warnings to allow decoupled setting from --enable-debug.

  runtests.pl will now run with picky compiler warnings enabled unless
  explicitly disabled.

Daniel Fandrich (1 Oct 2008)
- "make clean" now cleans out the docs and tests directories, too.

Daniel Stenberg (30 Sep 2008)
- The libcurl FTP code now returns CURLE_REMOTE_FILE_NOT_FOUND error when SIZE
  gets a 550 response back for the cases where a download (or NOBODY) is
  wanted. It still allows a 550 as response if the SIZE is used as part of an
  upload process (like if resuming an upload is requested and the file isn't
  there before the upload). I also modified the FTP test server and a few test
  cases accordingly to match this modified behavior.

Daniel Stenberg (29 Sep 2008)
- Daniel Egger provided a patch that allows you to disable proxy support in
  libcurl to somewhat reduce the size of the binary. Run configure
  --disable-proxy.

Daniel Fandrich (29 Sep 2008)
- Moved all signal-based name resolution timeout handling into a single new
  Curl_resolv_timeout function to reduce coupling.

Daniel Stenberg (29 Sep 2008)
- Ian Lynagh provided a patch that now makes CURLOPT_RANGE work fine for SFTP
  downloads!

- Maxim Ivanov filed bug report #2107803
  (https://curl.haxx.se/bug/view.cgi?id=2107803) "no CURLINFO_REDIRECT_URL in
  multi mode" together with a patch that fixed the problem.

Daniel Stenberg (25 Sep 2008)
- Emanuele Bovisio submitted bug report #2126435. We fixed the HTTP Digest
  auth code to not behave badly when getting a blank realm with
  realm="". https://curl.haxx.se/bug/view.cgi?id=2126435

Daniel Fandrich (23 Sep 2008)
- Make sure not to dereference the wrong UrlState proto union member when
  switching from one protocol to another in a single request (e.g.
  redirecting from HTTP to FTP as in test 1055) by resetting
  state.expect100header before every request.

Daniel Stenberg (23 Sep 2008)
- Introducing Jamie Lokier's function for date to epoch conversion used in the
  date parser function. This makes our function less dependent on system-
  provided functions and instead we do all the magic ourselves. We also no
  longer depend on the TZ environment variable. Switching to our own converter
  has some side-effect and they are noted here for future reference (taken
  from a mail by mr Lokier):

  time_t is not measured in seconds in the ANSI C standard - or even counted
  uniformly - weird platforms can use other numeric representations of dates
  in time_t - hence the difftime() function.

  On POSIX time_t is measured in UTC seconds, which means not including leap
  seconds.  But it's mentioned in a few places that some old POSIX-ish
  environments include leap seconds in their time_t counts...

  I'm pretty sure [the new implementation is] correct on anything truly POSIX.
  And it's obviously a lot less dependent on platform quirks and corner cases
  in many ways than the mktime() version.

- Rob Crittenden brought a patch to "add some locking for thread-safety to NSS
  implementation".

Daniel Stenberg (22 Sep 2008)
- Made the SOCKS code use the new Curl_read_plain() function to fix the bug
  Markus Moeller reported: https://curl.haxx.se/mail/archive-2008-09/0016.html

- recv() errors other than those equal to EAGAIN now cause proper
  CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
  disabled it until we can figure out another way to exercise that logic.

- Michael Goffioul filed bug report #2107377 "Problem with multi + GnuTLS +
  proxy" (https://curl.haxx.se/bug/view.cgi?id=2107377) that showed how a multi
  interface using program didn't work when built with GnuTLS and a CONNECT
  request was done over a proxy (basically test 502 over a proxy to a HTTPS
  site). It turned out the ssl connect function would get called twice which
  caused the second call to fail.

Daniel Fandrich (22 Sep 2008)
- Fixed test 539 to handle an out of memory condition that shows up now
  that memdebug.h is included in the test programs.

Yang Tse (20 Sep 2008)
- Fix regression in configure script which affected OpenSSL builds on MSYS.

Yang Tse (19 Sep 2008)
- configure script now checks availability of the alarm() function.

Daniel Fandrich (18 Sep 2008)
- Don't bother to install a SIGALRM handler unless alarm() is available.
  Also, leave the existing SIGALRM handler alone if the timeout is too small
  to handle.

Daniel Fandrich (17 Sep 2008)
- Removed reference to curl-ca-bundle.crt in the host verification failure
  error message.

Yang Tse (17 Sep 2008)
- Improve configure detection of gethostname(), localtime_r(), strstr(),
  getservbyport_r(), gethostbyaddr_r() and gethostbyname_r().

Yang Tse (14 Sep 2008)
- Improve configure detection of strcasecmp(), strcasestr(), strcmpi(),
  stricmp(), strlcat(), strncasecmp(), strncmpi() and strnicmp().

Yang Tse (13 Sep 2008)
- Disable tracking of fdopen() calls in the low-level memory leak tracking
  code when fdopen() is not available, to avoid compiler error.

Yang Tse (12 Sep 2008)
- Further adjust detection of strerror_r() in the configure process, and
  ensure that errno is not modified inside Curl_strerror().

Yang Tse (10 Sep 2008)
- Improve detection of gmtime_r(), strtoll(), sigaction(), strtok_r(),
  strdup() and ftruncate() in the configure process.

Daniel Fandrich (9 Sep 2008)
- Mike Revi discovered some swapped speed switches documented in the curl man
  page.

- Checked in some documentation and code improvements and fixes that I
  discovered in the FreeBSD ports system.

Daniel Stenberg (8 Sep 2008)
- Dmitry Kurochkin patched a problem: I have found bug in pipelining through
  proxy. I have a transparent proxy. When running with http_proxy environment
  variable not set my test completes fine (it goes through transparent
  proxy). When I set http_proxy variable my test hangs after the first
  downloaded is complete. Looks like the second handle never gets out from
  WAITDO state.

  The fix: It makes checkPendPipeline move 1 handler from pend pipe to send
  pipe if pipelining is not supported by server but there are no handles in
  send and recv pipes.

- Stefan Krause pointed out that libcurl would wrongly send away cookies to
  sites in cases where the cookie clearly has a very old expiry date. The
  condition was simply that libcurl's date parser would fail to convert the
  date and it would then count as a (timed-based) match. Starting now, a
  missed date due to an unsupported date format or date range will now cause
  the cookie to not match.

Daniel Fandrich (5 Sep 2008)
- Improved the logic that decides whether to use HTTP 1.1 features or not in a
  request.  Setting a specific version with CURLOPT_HTTP_VERSION overrides
  all other checks, but otherwise, a 1.0 request will be made if the server
  is known to support only 1.0 because it previously responded so and the
  connection was kept alive, or a response to a previous request on this handle
  came back as 1.0. The latter could take place in cases like redirection or
  authentication where several requests have to be made before the operation
  is complete.  If any one of the servers in a redirection chain supports only
  1.0, then remaining requests will be sent in 1.0 mode.

- Detect cases where an upload must be sent chunked and the server supports
  only HTTP 1.0 and return CURLE_UPLOAD_FAILED.

Daniel Stenberg (5 Sep 2008)
- Martin Drasar provided the CURLOPT_POSTREDIR patch. It renames
  CURLOPT_POST301 (but adds a define for backwards compatibility for you who
  don't define CURL_NO_OLDIES). This option allows you to now also change the
  libcurl behavior for a HTTP response 302 after a POST to not use GET in the
  subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
  patch somewhat before commit. The curl tool got a matching --post302
  option. Test case 1076 was added to verify this.

- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. By
  enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
  or FTPS), libcurl will gather lots of server certificate info and that info
  can then get extracted by a client after the request has completed with
  curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
  helped me test and smoothen out this feature.

  Unfortunately, this feature currently only works with libcurl built to use
  OpenSSL.

  This feature was sponsored by networking4all.com - thanks!

- Dmitriy Sergeyev pointed out that curl_easy_pause() didn't unpause properly
  during certain conditions. I also changed this code to use realloc() based
  on Daniel Fandrich's suggestion.

Guenter Knauf (4 Sep 2008)
- MingW32 non-configure builds are now largefile feature enabled by default.
  NetWare LIBC builds are also now largefile feature enabled by default.

Yang Tse (4 Sep 2008)
- Several fixes related with print formatting string directives.

Daniel Fandrich (3 Sep 2008)
- Search for the FreeBSD CA cert file /usr/local/share/certs/ca-root.crt

Daniel Fandrich (2 Sep 2008)
- Fixed an out of memory problem that caused torture test failures in tests
  706 and 707.

Daniel Stenberg (2 Sep 2008)
- Keith Mok added supported_protocols and supported_features to the pkg-config
  file for libcurl, and while doing that fix he unified with curl-config.in
  how the supported protocols and features are extracted and used, so both those
  tools should now always be synced.

Version 7.19.0 (1 September 2008)

Daniel Fandrich (29 Aug 2008)
- Added tests 1071 through 1074 to test automatic downgrading from HTTP 1.1
  to HTTP 1.0 upon receiving a response from the HTTP server.  Tests 1072
  and 1073 are similar to test 1069 in that they involve the impossible
  scenario of sending chunked data to a HTTP 1.0 server.  All these fail
  and are added to DISABLED.

- Added test 1075 to test --anyauth with Basic authentication.

Daniel Stenberg (29 Aug 2008)
- When libcurl was doing a HTTP POST and the server would respond with
  "Connection: close" and actually close the connection after the
  response-body, libcurl could still have outstanding data to send and it
  would not properly notice this and stop sending. This caused weirdness and
  sad faces. https://curl.haxx.se/bug/view.cgi?id=2080222

  Note that there are still reasons to consider libcurl's behavior when
  getting a >= 400 response code while sending data, as Craig Perras' note
  "http upload: how to stop on error" specifies:
  https://curl.haxx.se/mail/archive-2008-08/0138.html

Daniel Stenberg (28 Aug 2008)
- Dengminwen reported that libcurl would lock a (cookie) share twice (without
  an unlock in between) for a certain case and that in fact works when using
  regular windows mutexes but not with pthreads'! Locks should of course not
  get locked again so this is now fixed.
  https://curl.haxx.se/mail/lib-2008-08/0422.html

- I'm abandoning the system with the web site mirrors (but keeping download
  files bing mirrored) and thus I've changed the URL in the cookiejar header
  to no longer use curlm.haxx.se but instead use the main site curl.haxx.se

Daniel Fandrich (27 Aug 2008)
- Fixed test case 1065 by changing the handling of CURLOPT_UPLOAD to set
  the HTTP method to GET (or HEAD) when given a value of 0.

- Added test cases 1068 and 1069 to test a simple HTTP PUT from stdin.  Test
  case 1069 fails in a similar manner to test 1065 so is added to DISABLED.

Yang Tse (27 Aug 2008)
- Fix generation of MS VC6 .dsp file to make it support compilation of either
  dynamic (DLL) or static (LIB) libcurl libraries in debug and release modes.

Daniel Fandrich (26 Aug 2008)
- Fixed out of memory problems that caused torture test failures in tests
  1021 and 1067.

Yang Tse (26 Aug 2008)
- Added check and symbol definition for WIN32 file API usage in configure,
  supporting configure's --disable-largefile option for WIN32 targets also.

- Non-configure systems which do not use config-win32.h configuration file,
  and want to use the WIN32 file API, must define USE_WIN32_LARGE_FILES or
  USE_WIN32_SMALL_FILES as appropriate in their own configuration files.

Daniel Stenberg (23 Aug 2008)
- Running 'make ca-firefox' in the root build dir will now run the new
  firefox-db2pem.sh conversion script that converts a local Firefox db of ca
  certs into PEM format, suitable for use with a OpenSSL or GnuTLS built
  libcurl.

- Constantine Sapuntzakis fixed a bug when doing proxy CONNECT with the multi
  interface, and the proxy would send Connection: close during the
  authentication phase.  https://curl.haxx.se/bug/view.cgi?id=2069047

Daniel Fandrich (22 Aug 2008)
- Fixed a problem when --dump-header - was given with more than one URL,
  which caused an error when the second header was dumped due to stdout
  being closed.  Added test case 1066 to verify.  Also fixed a potential
  problem where a closed file descriptor might be used for an upload
  when more than one URL is given.

Yang Tse (22 Aug 2008)
- Improved libcurl's internal curl_m*printf() functions integral data type
  size and signedness handling.

- Internal adjustments to better select/differentiate when large/small file
  support is provided using WIN32 functions directly.

Daniel Fandrich (20 Aug 2008)
- Added an edited version of Vincent Le Normand's documentation of SFTP quote
  commands to the man pages.

Daniel Stenberg (20 Aug 2008)
- Phil Pellouchoud pointed out that the windows version of libcurl had a
  memory leak because it never called the OpenSSL function
  CRYPTO_cleanup_all_ex_data() as it was supposed to. This was because of a
  missing define in config-win32.h!

Gisle Vanem (18 Aug 2008)
- Updated lib/Makefile.Watcom with the option to use c-ares (USE_ARES=1).

Yang Tse (18 Aug 2008)
- Added test case 557 to verify libcurl's internal curl_m*printf() functions
  formatting functionality when handling signed and unsigned longs, as well as
  our curl_off_t data type.

Yang Tse (17 Aug 2008)
- OpenSSl enabled NetWare builds are changed to use the 'openssl' subdirectory
  when including the OpenSSL header files. This is the recommended setting, this
  prevents the undesired inclusion of header files with the same name as those
  of OpenSSL but which do not belong to the OpenSSL package. The visible change
  from previously released libcurl versions is that now OpenSSl enabled NetWare
  builds also define USE_OPENSSL in config files, and that OpenSSL header files
  must be located in a subdirectory named 'openssl'.

Yang Tse (16 Aug 2008)
- Library internal only C preprocessor macros FORMAT_OFF_T and FORMAT_OFF_TU
  remain in use as internal curl_off_t print formatting strings for the internal
  *printf functions which still cannot handle print formatting string directives
  such as "I64d", "I64u", and others available on MSVC, MinGW, Intel's ICC, and
  other DOS/Windows compilers.

Daniel Fandrich (15 Aug 2008)
- Added test case 1063 to test invalid long file ranges with file: URLs and
  1064 to test multiple http PUTs.

- Added test case 1065 to test a PUT with a single file but two URLs. This
  was discovered to be problematic while investigating an incident reported by
  Von back in May.  curl in this case doesn't include a Content-Length: or
  Transfer-Encoding: chunked header which is illegal. This test case is
  added to DISABLED until a solution is found.

Yang Tse (15 Aug 2008)
- C preprocessor macros used internally and equally available externally which
  aid in the use of the curl_off_t data type are named: CURL_FORMAT_CURL_OFF_T,
  CURL_FORMAT_CURL_OFF_TU, CURL_SIZEOF_CURL_OFF_T, CURL_SUFFIX_CURL_OFF_T,
  CURL_SUFFIX_CURL_OFF_TU, CURL_OFF_T_C and CURL_OFF_TU_C.

Yang Tse (13 Aug 2008)
- The size of long is a build time characteristic and as such it is now recorded
  in curlbuild.h as CURL_SIZEOF_LONG. Definition now done from configure process
  and in CVS curlbuild.h.dist for non-configure systems.

Daniel Fandrich (12 Aug 2008)
- Fixed a buffer overflow problem in Curl_proxyCONNECT that could occur
  when a server responded with long headers and data.  Luckily, the buffer
  overflowed into another unused buffer, so no actual harm was done.
  Added test cases 1060 and 1061 to verify.

Daniel Stenberg (12 Aug 2008)
- Andy Tsouladze fixed runtests.pl to not attempt to execute the stunnel
  _directory_ if that happened to appear in the path!

Yang Tse (12 Aug 2008)
- Added macros for minimum-width signed and unsigned curl_off_t integer
  constants CURL_OFF_T_C and CURL_OFF_TU_C. The clever double helper macro
  used internally to provide its functionality is thanks to Lars Nilsson.

Daniel Fandrich (11 Aug 2008)
- Fixed a boundary condition error in ftp_readresp() whereby a non-terminal
  line of a multiline FTP response whose last byte landed exactly at the end
  of the BUFSIZE-length buffer would be treated as the terminal response
  line.  The following response code read in would then actually be the
  end of the previous response line, and all responses from then on would
  correspond to the wrong command. Test case 1062 verifies this.

- Stop closing a never-opened ftp socket.

Daniel Stenberg (11 Aug 2008)
- Constantine Sapuntzakis filed bug report #2042430
  (https://curl.haxx.se/bug/view.cgi?id=2042430) with a patch. "NTLM Windows
  SSPI code is not thread safe". This was due to libcurl using static
  variables to tell wether to load the necessary SSPI DLL, but now the loading
  has been moved to the more suitable curl_global_init() call.

- Constantine Sapuntzakis filed bug report #2042440
  (https://curl.haxx.se/bug/view.cgi?id=2042440) with a patch. He identified a
  problem when using NTLM over a proxy but the end-point does Basic, and then
  libcurl would do wrong when the host sent "Connection: close" as the proxy's
  NTLM state was erroneously cleared.

Yang Tse (11 Aug 2008)
- Added missing signed and unsigned curl_off_t integer constant suffixes for
  internal and external use. CURL_SUFFIX_CURL_OFF_T, CURL_SUFFIX_CURL_OFF_TU.

Daniel Fandrich (7 Aug 2008)
- Fixed an uninitialized variable in multi_runsingle() that could cause a
  request to prematurely end.

- Added test1059 to test the FTP proxy tunnel problem fixed July 11.

Yang Tse (7 Aug 2008)
- Added curlbuild.h and curlrules.h header files to libcurl's public headers.
  File curlbuild.h is a generated file on configure-capable systems. This is
  a first step towards configure-based info in public headers. Currently only
  used to provide support for a curl_off_t data type which is not gated to
  off_t. Further details are documented inside these mentioned header files.

- Fix CURL_CHECK_DEF so that when the expansion of the preprocessor symbol
  results in a set of double-quoted strings, this macro will now return an
  expansion which consists of a single double-quoted string as the result of
  concatenating all of them.

- Skip data type check in DO_CURL_OFF_T_CHECK macro when argument is empty.

- Adjusted testcurl.pl to copy checked out curlbuild.h.dist as curlbuild.h
  for non-configure targets when the host system doesn't run buildconf.bat.

- Prevent buildconf from removing 'Makefile' and 'missing' files. This would
  blow away our CVS checked files 'missing' and 'hiper/Makefile'.

- Remove adjustment done to testcurl.pl to verify if change introduced by
  Guenter Knauf in lib/Makefile.netware is enough to get the netware autobuilds
  going again.

Yang Tse (5 Aug 2008)
- Changes done to buildconf script. Validate that autom4te and autoconf, as
  well as aclocal and automake, versions match. Improve removal of previous
  run generated files. Remove verbose debug logging of aclocal on Solaris.

Daniel Stenberg (5 Aug 2008)
- Yehoshua Hershberg found a problem that would make libcurl re-use a
  connection with the multi interface even if a previous use of it caused a
  CURLE_PEER_FAILED_VERIFICATION to get returned. I now make sure that failed
  SSL connections properly close the connections.

Daniel Stenberg (4 Aug 2008)
- Test cases 1051, 1052 and 1055 were added by Daniel Fandrich on July 30 and
  proved how PUT and POST with a redirect could lead to a "hang" due to the
  data stream not being rewound properly when it had to in order to get sent
  properly (again) to the subsequent URL. This is now fixed and these test
  cases are no longer disabled.

Yang Tse (4 Aug 2008)
- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
  Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
  version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
  no matter if the system is AIX or not. To keep the traditional behaviour,
  and an uniform one across autoconf versions AC_AIX is replaced with our
  own internal macro CURL_CHECK_AIX_ALL_SOURCE.

Daniel Stenberg (4 Aug 2008)
- Test case 1041 (added by Daniel Fandrich July 14th) proved a bug where PUT
  with -C - sent garbage in the Content-Range: header. I fixed this problem by
  making sure libcurl always sets the size of the _entire_ upload if an app
  attemps to do resumed uploads since libcurl simply cannot know the size of
  what is currently at the server end. Test 1041 is no longer disabled.

Yang Tse (2 Aug 2008)
- No longer test availability of the gdi32 library, nor use it for linking, even
  when we have been doing this since revision 1.47 of configure.ac 4 years and
  5 months ago when cross-compiling a Windows target. We actually don't use any
  function from the Windows GDI (Graphics Device Interface) related with drawing
  or graphics-related operations.

Daniel Fandrich (1 Aug 2008)
- Added support for --append on SFTP uploads. Unfortunately, OpenSSH doesn't
  support this so it goes untested.

Yang Tse (1 Aug 2008)
- Configure process now checks if the preprocessor _REENTRANT symbol is already
  defined. If it isn't currently defined a set of checks are performed to test
  if its definition is required to make visible to the compiler a set of *_r
  functions. Finally, if _REENTRANT is already defined or needed it takes care
  of making adjustments necessary to ensure that it is defined equally for the
  configure process tests and generated config file.

- Removed definition of CURL_CHECK_WORKING_RESOLVER from acinclude.m4 it has
  not been in use since revision 1.81 of configure.in 6 years, 9 months ago.

Daniel Fandrich (31 Jul 2008)
- Fixed parsing of an IPv6 proxy address to support a scope identifier,
  as well as IPv4 addresses in IPv6 format. Also, better handle the case
  of a malformatted IPv6 address (avoid empty and NULL strings).

- Fixed a problem with any FTP URL or any URLs containing an IPv6 address
  being mangled when passed to proxies when CURLOPT_PORT is also set
  (reported by Pramod Sharma).

- User names embedded in proxy URLs without a password were parsed
  incorrectly--the host name is treated as part of the user name and the
  port number becomes the password.  This can be observed in test 279
  (was KNOWN_ISSUE #54).

Daniel Stenberg (30 Jul 2008)
- Phil Blundell added the CURLOPT_ADDRESS_SCOPE option, as well as adjusted
  the URL parser to allow numerical IPv6-addresses to be specified with the
  scope given, as per RFC4007 - with a percent letter that itself needs to be
  URL escaped. For example, for an address of fe80::1234%1 the HTTP URL is:
  "http://[fe80::1234%251]/"

- PHP's bug report #43158 (http://bugs.php.net/bug.php?id=43158) identifies a
  true bug in libcurl built with OpenSSL. It made curl_easy_getinfo() more or
  less always return 0 for CURLINFO_SSL_VERIFYRESULT because the function that
  would set it to something non-zero would return before the assign in almost
  all error cases. The internal variable is now set to non-zero from the start
  of the function only to get cleared later on if things work out fine.

- Made the curl tool's -w option support the %{ssl_verify_result} variable

Daniel Fandrich (30 Jul 2008)
- Added test cases 1052 through 1055 to test uploading data from files
  during redirects.  Test cases 1052 and 1055 show problems (maybe the same
  root cause as 1051) and are disabled.

- Fixed a couple of buffer overflows in the MS-DOS port of the curl tool.

Daniel Fandrich (29 Jul 2008)
- Fixed --use-ascii to properly convert text files on Symbian OS, MS-DOS
  and OS/2.

- Added test case 1051 to test Location: following with PUT, as reported
  by Ben Sutcliffe.  The test when run manually shows a problem in curl
  so it's disabled.

Daniel Fandrich (28 Jul 2008)
- Fixed display of the interface bind address in the trace output when it's
  an IPv6 address.

- Added test cases 1045 through 1049 as simple tests of --interface using the
  localhost interface.

- Added test case 1050 to test --ftp-port with an IPv6 address

Daniel Stenberg (26 Jul 2008)
- David Bau filed bug report #2026240 "CURL_READFUNC_PAUSE leads to buffer
  overrun" (https://curl.haxx.se/bug/view.cgi?id=2026240) identifying two
  problems, and providing the fix for them:

  - CURL_READFUNC_PAUSE did in fact not pause the _sending_ of data that it is
    designed for but paused _receiving_ of data!

  - libcurl didn't internally set the read counter to zero when this return
    code was detected, which would potentially lead to junk getting sent to
    the server.

Daniel Fandrich (26 Jul 2008)
- Added test 1044 to test large file support in ftp with -I.

- Eliminate a unnecessary socket creation in Curl_getaddrinfo for an IPv4
  address in an IPv6 capable libcurl.

- Added feature in runtests.pl to select tests based on key word.

Daniel Fandrich (23 Jul 2008)
- Changed the long logfile elision code in runtests.pl to properly handle
  lines ending in \r.

- Changed references to TRUE and FALSE in the curl_easy_setopt man page to
  1 and zero, respectively, since TRUE and FALSE aren't part of the
  libcurl API.

Daniel Stenberg (23 Jul 2008)
- I went over the curl_easy_setopt man page and replaced most references to
  non-zero with the fixed value of 1. We should strive at making options
  support '1' for enabling them mentioned explicitly, as that then will allow
  us for to extend them in the future without breaking older programs.

  Possibly we should even introduce a fancy define to use instead of '1' all
  over...

Yang Tse (21 Jul 2008)
- Use the sreadfrom() wrapper to replace recvfrom() in our code.

Yang Tse (20 Jul 2008)
- when recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
  now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.

Yang Tse (17 Jul 2008)
- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
  to the data type pointed by its respective argument and not the pointer type.

Yang Tse (16 Jul 2008)
- Configure process now checks availability of recvfrom() socket function and
  finds out its return type and the types of its arguments. Added definitions
  for non-configure systems config files, and introduced macro sreadfrom which
  will be used on udp sockets as a recvfrom() wrapper.

Yang Tse (15 Jul 2008)
- Added description/comment to include paths used in several Makefile.am files.
  Added automake option nostdinc to test servers makefile and modified libcurl
  external headers include path for libtest programs.

Daniel Fandrich (14 Jul 2008)
- Added test1040 through test1043 to test -C - on HTTP. Test 1041 failed so
  it's added to DISABLED.

Yang Tse (14 Jul 2008)
- HTTP_ONLY definition check in lib/setup.h is now done once that configuration
  file has been included. In this way if symbol is defined in the config file
  it will no longer be ignored.  Removed inclusion of remaining system header
  files from configuration files. Moved _REENTRANT definition up/earlier in
  lib/setup.h

Yang Tse (11 Jul 2008)
- Added missing multiple header inclusion prevention definition for header
  file content_encoding.h

Daniel Fandrich (11 Jul 2008)
- Fixed test 553 to pass the torture test.

Daniel Stenberg (11 Jul 2008)
- Daniel Fandrich found out we didn't pass on the user-agent properly when
  doing "proxy-tunnels" with non-HTTP prototols and that was simply because
  the code assumed the user-agent was only needed for HTTP.

Daniel Fandrich (10 Jul 2008)
- Changed slightly the SFTP quote commands chmod, chown and chgrp to only
  set the attribute that has changed instead of all possible ones. Hopefully,
  this will solve the "Permission denied" problem that Nagarajan Sreenivasan
  reported when setting some modes, but regardless, it saves a protocol
  round trip in the chmod case.

- Added test cases 1038 and 1039 to test Adrian Kreher's report that ftp
  uploads with -C - didn't resume properly, but the tests pass.

Yang Tse (10 Jul 2008)
- Peter Lamberg filed bug report #2015126: "poll gives WSAEINVAL when POLLPRI
  is set in fdset.events" (https://curl.haxx.se/bug/view.cgi?id=2015126) which
  exactly pinpointed the problem only triggered on Windows Vista, provided
  reference to docs and also a fix. There is much work behind Peter Lamberg's
  excellent bug report. Thank You!

Daniel Fandrich (9 Jul 2008)
- Added tests 1036 and 1037 to verify resumed ftp downloads with -C -

Daniel Stenberg (9 Jul 2008)
- Andreas Schuldei improved Phil Blundell's patch for IPv6 using c-ares, and I
  edited it slightly. Now you should be able to use IPv6 addresses fine even
  with libcurl built to use c-ares.

Daniel Fandrich (9 Jul 2008)
- Fixed an OOM handling problem that cause test 11 to fail the torture test.

Daniel Fandrich (8 Jul 2008)
- Fixed test 554 to pass the torture test.

Daniel Fandrich (7 Jul 2008)
- Added test cases 1034 & 1035 to test IDN name conversion failures.

Daniel Stenberg (7 Jul 2008)
- Scott Barrett provided a test case for a segfault in the FTP code and the
  fix for it. It occured when you did a FTP transfer using
  CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
  switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
  cleared properly.  Scott's test case is now known as test 539 and it
  verifies the fix.

Daniel Stenberg (3 Jul 2008)
- Phil Blundell provided a fix for libcurl's treatment of unexpected 1xx
  response codes. Previously libcurl would hang on such occurances. I added
  test case 1033 to verify.

- Introcuding a new timestamp for curl_easy_getinfo():
  CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
  handshake/connection is completed. Which typically is SSL, TLS or SSH and by
  using this you can figure out the application layer's own connect time. You
  can extract the time stamp using curl's -w option and the new variable named
  'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.

Daniel Fandrich (2 Jul 2008)
- Support Open Watcom C on Linux (as well as Windows).

Yang Tse (2 Jul 2008)
- The previously committed fix for bug report #1999181 prevented using the
  monotonic clock on any system without an always supported POSIX compliant
  implementation. Now the POSIX compliant configuration check is removed and
  will fallback to gettimeofday when the monotonic clock is unavailable at
  run-time.

- The configure process will now halt when sed, grep, egrep or ar programs
  can not be found among the directories in PATH variable.

Daniel Stenberg (1 Jul 2008)
- Rolland Dudemaine provided fixes to get libcurl to build for the INTEGRITY
  operating system.

Daniel Stenberg (30 Jun 2008)
- Made the internal printf() support %llu properly to print unsigned long longs.

- Stephen Collyer and Tor Arntsen helped identify a flaw in the range code
  which output the range using a signed variable where it should rather use
  unsigned.

Yang Tse (29 Jun 2008)
- John Lightsey filed bug report #1999181: "CLOCK_MONOTONIC always fails on
  some systems" (https://curl.haxx.se/bug/view.cgi?id=1999181). The problem was
  that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
  macro when checking monotonic clock availability. This is now fixed and the
  monotonic clock will not be used unless the feature test macro is defined
  with a value greater than zero indicating always supported.

Daniel Fandrich (25 Jun 2008)
- Honour --stderr with the -v option.

- Fixed a file handle leak in the command line client if more than one
  --stderr option was given.

Daniel Stenberg (22 Jun 2008)
- Eduard Bloch filed the debian bug report #487567
  (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487567) pointing out that
  libcurl used Content-Range: instead of Range when doing a range request with
  --head (CURLOPT_NOBODY). This is now fixed and test case 1032 was added to
  verify.

Daniel Fandrich (21 Jun 2008)
- Stopped using ranges in scanf character sequences (e.g. %[a-z]) since that
  is not ANSI C, just a common extension.  This caused problems on
  at least Open Watcom C.

Yang Tse (20 Jun 2008)
- Modified configuration script to actually verify if the compiler is good
  enough at detecting compilation errors or at least it has been properly
  configured to do so. Configuration heavily depends on this capability, so
  if this compiler sanity check fails the configuration process will now fail.

Daniel Stenberg (20 Jun 2008)
- Phil Pellouchoud found a case where libcurl built with NSS failed to
  handshake with a SSLv2 server, and it turned out to be because it didn't
  recognize the cipher named "rc4-md5". In our list that cipher was named
  plainly "rc4". I've now added rc4-md5 to work as an alias as Phil reported
  that it made things work for him again.

- Hans-Jurgen May pointed out that trying SCP or SFTP over a SOCKS proxy
  crashed libcurl. This is now addressed by making sure we use "plain send"
  internally when doing the socks handshake instead of the Curl_write()
  function which is designed to use the "target" protocol. That's then SCP or
  SFTP in this case. I also took the opportunity and cleaned up some ssh-
  related #ifdefs in the code for readability.

Daniel Stenberg (19 Jun 2008)
- Christopher Palow fixed a curl_multi_socket() issue which previously caused
  libcurl to not tell the app properly when a socket was closed (when the name
  resolve done by c-ares is completed) and then immediately re-created and put
  to use again (for the actual connection). Since the closure will make the
  "watch status" get lost in several event-based systems libcurl will need to
  tell the app about this close/re-create case.

- Dengminwen found a bug in the connection re-use function when using the
  multi interface with pipelining enabled as it would wrongly check for,
  detect and close "dead connections" even though that connection was already
  in use!

Daniel Fandrich (18 Jun 2008)
- Added SSH failure test cases 628-632

- Fixed a memory leak in the command-line tool that caused a valgrind error.

Daniel Stenberg (18 Jun 2008)
- Rob Crittenden brought a fix for the NSS layer that makes libcurl no longer
  always fire up a new connection rather than using the existing one when the
  multi interface is used. Original bug report:
  https://bugzilla.redhat.com/show_bug.cgi?id=450140

Yang Tse (18 Jun 2008)
- Internal configure script improvement. No longer break out of shell "for"
  statements from inside AC_FOO_IFELSE macros, otherwise temporary macro files
  are not properly removed.

Daniel Fandrich (12 Jun 2008)
- Fixed curl-config --ca which wasn't being exported by configure.

Daniel Stenberg (11 Jun 2008)
- I did a cleanup of the internal generic SSL layer and how the various SSL
  libraries are supported. Starting now, each underlying SSL library support
  code does a set of defines for the 16 functions the generic layer (sslgen.c)
  uses (all these new function defines use the prefix "curlssl_"). This
  greatly simplified the generic layer in readability by involving much less
  #ifdefs and other preprocessor stuff and should make it easier for people to
  make libcurl work with new SSL libraries.

  Hopefully I can later on document these 16 functions somewhat as well.

  I also made most of the internal SSL-dependent functions (using Curl_ssl_
  prefix) #defined to nothing when no SSL support is requested - previously
  they would unnecessarily call mostly empty functions.

  I've built libcurl with OpenSSL and GnuTLS and without SSL to test this and
  I've also tried building with NSS but the NSS support is a mystery to me and
  I failed to build libcurl with the NSS libraries I have installed. We really
  should A) improve our configure script to detect unsuitable NSS versions
  already at configure time and B) document our requirements better for the
  SSL libraries.

Daniel Stenberg (10 Jun 2008)
- I made the OpenSSL code build again with OpenSSL 0.9.6. The CRLFILE
  functionality killed it due to its unconditional use of
  X509_STORE_set_flags...

Daniel Stenberg (8 Jun 2008)
- Due to the three new libcurl changes and the massive command line option
  change I decided we'll mark it by bumping the next release number to 7.19.0!

- curl the tool now deals with its command line options somewhat differently!
  All boolean options (such as -O, -I, -v etc), both short and long versions,
  now always switch on/enable the option named. Using the same option multiple
  times thus make no difference. To switch off one of those options, you need
  to use the long version of the option and type --no-OPTION. Like to disable
  verbose mode you use --no-verbose!

- Added --remote-name-all to curl, which if used changes the default for all
  given URLs to be dealt with as if -O is used. So if you want to disable that
  for a specific URL after --remote-name-all has been used, you muse use -o -
  or --no-remote-name.

Daniel Stenberg (6 Jun 2008)
- Axel Tillequin and Arnaud Ebalard added support for CURLOPT_ISSUERCERT, for
  OpenSSL, NSS and GnuTLS-built libcurls.

- Axel Tillequin and Arnaud Ebalard added support for CURLOPT_CRLFILE, for
  OpenSSL, NSS and GnuTLS-built libcurls.

- Added CURLINFO_PRIMARY_IP as a new information retrievable with
  curl_easy_getinfo. It returns a pointer to a string with the most recently
  used IP address. Modified test case 500 to also verify this feature. The
  implementing of this feature was sponsored by Lenny Rachitsky at NeuStar.

Version 7.18.2 (4 June 2008)

Daniel Fandrich (3 Jun 2008)
- Fixed a problem where telnet data would be lost if an EWOULDBLOCK
  condition were encountered.

Marty Kuhrt (1 Jun 2008)
- Updated main.c to return CURLE_OK if PARAM_HELP_REQUESTED was returned
  from getparameter instead of CURLE_FAILED_INIT.  No point in returning
  an error if --help or --version were requested.

Daniel Stenberg (28 May 2008)
- Emil Romanus found a problem and helped me repeat it. It occured when using
  the curl_multi_socket() API with HTTP pipelining enabled and could lead to
  the pipeline basically stalling for a very long period of time until it took
  off again.

- Jeff Weber reported memory leaks with aborted SCP and SFTP transfers and
  provided excellent repeat recipes. I fixed the cases I managed to reproduce
  but Jeff still got some (SCP) problems even after these fixes:
  https://curl.haxx.se/mail/lib-2008-05/0342.html

Daniel Stenberg (26 May 2008)
- Bug report #1973352 (https://curl.haxx.se/bug/view.cgi?id=1973352) identified
  how the HTTP redirect following code didn't properly follow to a new URL if
  the new url was but a query string such as "Location: ?moo=foo". Test case
  1031 was added to verify this fix.

- Andreas Faerber and Scott McCreary made (lib)curl build for the Haiku OS.

Yang Tse (26 May 2008)
- David Rosenstrauch reported that header files spnegohelp.h and
  openssl/objects.h were needed to compile SPNEGO support.

Daniel Fandrich (22 May 2008)
- Made sure to pass longs in to curl_easy_setopt where necessary in the
  example programs and libtest code.

Daniel Stenberg (19 May 2008)
- When trying to repeat a multi interface problem I fell over a few multi
  interface problems:

  o with pipelining disabled, the state should never be set to WAITDO but
    rather go straight to DO

  o we had multiple states for which the internal function returned no socket
    at all to wait for, with the effect that libcurl calls the socket callback
    (when curl_multi_socket() is used) with REMOVE prematurely (as it would be
    added again within very shortly)

  o when in DO and DOING states, the HTTP and HTTPS protocol handler functions
    didn't return that the socket should be waited for writing, but instead it
    was treated as if no socket was needing monitoring so again REMOVE was
    called prematurely.

Daniel Stenberg (13 May 2008)
- Added test case 556 that uses curl_easy_send() and curl_easy_recv()

Daniel Stenberg (9 May 2008)
- Introducing curl_easy_send() and curl_easy_recv(). They can be used to send
  and receive data over a connection previously setup with curl_easy_perform()
  and its CURLOPT_CONNECT_ONLY option. The sendrecv.c example was added to
  show how they can be used.

Yang Tse (9 May 2008)
- Internal time differences now use monotonic time source if available.
  This also implies the removal of the winmm.lib dependency for WIN32.

Daniel Stenberg (9 May 2008)
- Stefan Krause reported a busy-looping case when using the multi interface
  and doing CONNECT to a proxy. The app would then busy-loop until the proxy
  completed its response.

Michal Marek (9 May 2008)
- Make Curl_write and it's callees accept a const pointer, in preparation
  of tetetest's patch for curl_easy_send()

Daniel Stenberg (7 May 2008)
- Liam Healy filed the debian bug report #480044
  (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=480044) identifying a
  segfault when using krb5 ftp, but the krb4 code had the same problem.

Yang Tse (7 May 2008)
- Christopher Palow provided the patch (edited by me) that introduces the
  use of microsecond resolution keys for internal splay trees.

Daniel Stenberg (4 May 2008)
- Yuriy Sosov pointed out a configure fix for detecting c-ares when that is
  built debug-enabled.

Daniel Stenberg (3 May 2008)
- Ben Van Hof filed bug report #1945240: "libcurl sometimes sends body twice
  when using CURL_AUTH_ANY" (https://curl.haxx.se/bug/view.cgi?id=1945240).
  The problem was that when libcurl rewound a stream meant for upload when it
  would prepare for a second request, it could accidentally continue the
  sending of the rewound data on the first request instead of on the second.
  Ben also provided test case 1030 that verifies this fix.

Daniel Stenberg (3 May 2008)
- Jean-Francois Bertrand reported a libcurl crash with CURLOPT_TCP_NODELAY
  since libcurl used getprotobyname() and that isn't thread-safe. We now
  switched to use IPPROTO_TCP unconditionally, but perhaps the proper fix is
  to detect the thread-safe version of the function and use that.
  https://curl.haxx.se/mail/lib-2008-05/0011.html

Daniel Stenberg (1 May 2008)
- Bart Whiteley provided a patch that made libcurl work properly when an app
  uses the CURLOPT_OPENSOCKETFUNCTION callback to create a unix domain socket
  to a http server.

Daniel Stenberg (29 Apr 2008)
- To make it easier for applications that want lots of magic stuff done on
  redirections and thus cannot use CURLOPT_FOLLOWLOCATION easily, we now
  introduce the new CURLINFO_REDIRECT_URL option that lets applications
  extract the URL libcurl would've redirected to if it had been told to. This
  then enables the application to continue to that URL as it thinks is
  suitable, without having to re-implement the magic of creating the new URL
  from the Location: header etc. Test 1029 verifies it.

Yang Tse (29 Apr 2008)
- Improved easy interface resolving timeout handling in c-ares enabled builds

Daniel Fandrich (28 Apr 2008)
- Added test 1028 to test an HTTP redirect to a FTP URL.

Daniel Stenberg (28 Apr 2008)
- Norbert Frese filed bug report #1951588: "Problem with curlftpfs and
  libcurl" (https://curl.haxx.se/bug/view.cgi?id=1951588) which seems to be an
  identical report to what Denis Golovan reported in
  https://curl.haxx.se/mail/lib-2008-02/0108.html The FTP code didn't reset the
  user/password pointers properly even though there might've been a new
  struct/cconnection getting used.

Daniel Stenberg (26 Apr 2008)
- Reverted back to use automake 1.9.6 in the next release (from automake
  1.10.1) since it *still* suffers from Solaris-related bugs. Our previous
  automake 1.10 problem was reported in bug #1701360
  (https://curl.haxx.se/bug/view.cgi?id=1701360) and this recent problem was
  bug #1944825 (https://curl.haxx.se/bug/view.cgi?id=1944825). I have not
  personally approached the automake team about either one of these but I
  figure we need a Solaris 10 guy to do it!

Yang Tse (25 Apr 2008)
- Added 'timeout' and 'delay' attributes support for the test harness
  <command> subsection.

Daniel Fandrich (24 Apr 2008)
- Made --stderr able to redirect all stderr messages.

Yang Tse (23 Apr 2008)
- Improve synchronization between test harness runtests.pl script
  and test harness servers to minimize risk of false test failures.

Daniel Fandrich (22 Apr 2008)
- Added support for running on Symbian OS.

Daniel Fandrich (18 Apr 2008)
- Added test cases 1026 and 1027 to do some rudimentary tests on the --manual
  and --help options.

Michal Marek (14 Apr 2008)
- allow disabling the typechecker by defining CURL_DISABLE_TYPECHECK, as
  discussed in https://curl.haxx.se/mail/lib-2008-04/0291.html

Daniel Stenberg (14 Apr 2008)
- Stefan Krause reported a case where the OpenSSL handshake phase wasn't
  properly acknowledging the timeout values, like if you pulled the network
  plug in the midst of it.

- Andre Guibert de Bruet fixed a second case of not checking the malloc()
  return code in the Negotiate code.

- Sandor Feldi reported bug #1942022
  (https://curl.haxx.se/bug/view.cgi?id=1942022) pointing out a mistake in the
  lib/Makefile.vc[68] makefiles' release-ssl-dll target.

- Brock Noland reported that curl behaved differently depending on which order
  you used -i and -I.

Daniel Stenberg (12 Apr 2008)
- Andre Guibert de Bruet found and fixed a case where malloc() was called but
  was not checked for a NULL return, in the Negotiate code.

Daniel Fandrich (9 Apr 2008)
- Added test cases 1024 & 1025 to test a scenario similar to the one reported
  by Ben Combee where libcurl would send the wrong cookie to a redirected
  server.  libcurl was doing the right thing in these test cases.

Michal Marek (7 Apr 2008)
- Fix the MIT / Heimdal check for good:
  Define HAVE_GSSMIT if <gssapi/{gssapi.h,gssapi_generic.h,gssapi_krb5.h}> are
  available, otherwise define HAVE_GSSHEIMDAL if <gssapi.h> is available.

  Only define GSS_C_NT_HOSTBASED_SERVICE to gss_nt_service_name if
  GSS_C_NT_HOSTBASED_SERVICE isn't declared by the gssapi headers. This should
  avoid breakage in case we wrongly recognize Heimdal as MIT again.

Daniel Stenberg (5 Apr 2008)
- Alexey Simak fixed curl_easy_reset() to reset the max redirect limit properly

- Based on the Debian bug report #474224 that complained about the FTP error
  message when libcurl doesn't get a 220 back immediately on connect, I now
  changed it to be more specific on what the problem is. Also worth noticing:
  while the bug report contains an example where the response is:

    421 There are too many connected users, please try again later

  we cannot assume that the error message will always be this readable nor
  that it fits within a particular boundary etc.

Daniel Fandrich (3 Apr 2008)
- Added test627 to test SFTP with CURLOPT_NOBODY

Daniel Stenberg (3 Apr 2008)
- Setting CURLOPT_NOBODY to FALSE will now switch the HTTP request method to
  GET simply because previously when you set CURLOPT_NOBODY to TRUE first and
  then FALSE you'd end up in a broken state where a HTTP request would do a
  HEAD by still act a lot like for a GET and hang waiting for the content etc.

- Scott Barrett added support for CURLOPT_NOBODY over SFTP

Daniel Fandrich (3 Apr 2008)
- Made sure that curl_global_init is called in all the multithreaded
  example programs.

Michal Marek (31 Mar 2008)
- Removed the generated ca-bundle.h file. The verbatim value of $ca and
  $capath is known to configure, so it can be defined in config.h instead.

Daniel Stenberg (31 Mar 2008)
- Added CURLFORM_STREAM as a supported option to curl_formadd() to allow an
  application to provide data for a multipart with the read callback. Note
  that the size needs to be provided with CURLFORM_CONTENTSLENGTH when the
  stream option is used. This feature is verified by the new test case
  554. This feature was sponsored by Xponaut.

Daniel Fandrich (30 Mar 2008)
- Changed the makefile so the doc/examples/ programs are never built in a
  normal build/install (only with the 'make check' target), so that a
  build failure in the examples isn't fatal.

Version 7.18.1 (30 March 2008)

Daniel Stenberg (28 Mar 2008)
- Stephen Collyer pointed out that configure --with-libssh2 without a given
  path didn't work properly.

Daniel Stenberg (27 Mar 2008)
- As found out and reported by Dan Petitt, libcurl didn't show progress/call
  the progress callback for the first (potentially huge) piece of body data
  sent together with the POST request headers in the initial send().

Daniel Stenberg (25 Mar 2008)
- Made setting the CURLOPT_SSL_CTX_FUNCTION option return a failure in case
  libcurl wasn't built to use OpenSSL as that is a prerequisite for this
  option to function!

Daniel Stenberg (22 Mar 2008)
- Fixed the problem with doing a zero byte SCP transfer, verified with test
  case 617 (which was added by Daniel Fandrich 5 Mar 2008).

Daniel Fandrich (20 Mar 2008)
- Fixed a problem where curl-config --protocols could erroneously show LDAPS
  support when curl didn't even have regular LDAP support.  It looks like
  this could happen when the --enable-ldaps configure switch is given but
  configure couldn't find the LDAP headers or libraries.

Michal Marek (20 Mar 2008)
- Added --with-ca-path=DIRECTORY configure option to use an openSSL CApath by
  default instead of a ca bundle. The configure script will also look for a
  ca path if no ca bundle is found and no option given.

- Fixed detection of previously installed curl-ca-bundle.crt

Daniel Fandrich (18 Mar 2008)
- Added test 626 to reproduce an infinite loop when given an invalid
  SFTP quote command reported by Vincent Le Normand, and fixed it.

Michal Marek (18 Mar 2008)
- Added curl_easy_getinfo typechecker.

- Added macros for curl_share_setopt and curl_multi_setopt to check at least
  the correct number of arguments.

Daniel Fandrich (13 Mar 2008)
- Added tests 622-625 to test SFTP/SCP uploads. Test 625 was an attempt to
  reproduce the --ftp-create-dirs problem reported by Brian Ulm, but that
  seems to need a call curl_easy_reset() which this test case doesn't do.

Daniel Stenberg (13 Mar 2008)
- Brian Ulm figured out that if you did an SFTP upload with
  CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
  handle and uploaded another file to another directory that needed to be
  created, the second upload would fail. Another case of a state variable that
  wasn't properly reset between requests.

- I rewrote the 100-continue code to use a single state variable instead of
  the previous two ones. I think it made the logic somewhat clearer.

Daniel Stenberg (11 Mar 2008)
- Dmitry Popov filed bug report #1911069
  (https://curl.haxx.se/bug/view.cgi?id=1911069) that identified a race
  condition in the name resolver code when the DNS cache is shared between
  multiple easy handles, each running in simultaneous threads that could cause
  crashes.

- Added a macro for curl_easy_setopt() that accepts three arguments and simply
  does nothing with them, just to make sure libcurl users always use three
  arguments to this function. Due to its use of ... for the third argument, it
  is otherwise hard to detect abuse.

Michal Marek (11 Mar 2008)
- Added a type checking macro for curl_easy_setopt(), needs gcc-4.3 and only
  works in C mode atm (https://curl.haxx.se/mail/lib-2008-02/0267.html ,
  https://curl.haxx.se/mail/lib-2008-02/0292.html )

Daniel Fandrich (10 Mar 2008)
- Added tests 618-621 to test SFTP/SCP transfers of more than one file
  (test 620 tests the just-fixed problem reported by Brian Ulm).

Daniel Stenberg (9 Mar 2008)
- Brian Ulm reported a crash when doing a second SFTP transfer on a re-used
  easy handle if curl_easy_reset() was used between them. I fixed it and Brian
  verified that it cured his problem.

- Brian Ulm reported that if you first tried to download a non-existing SFTP
  file and then fetched an existing one and re-used the handle, libcurl would
  still report the second one as non-existing as well! I fixed it and Brian
  verified that it cured his problem.

Michal Marek (6 Mar 2008)
- Fix the gssapi configure check to detect newer MIT Kerberos (patch by
  Michael Calmer)

Yang Tse (6 Mar 2008)
- Fix regression on Curl_socket_ready() and Curl_poll() so that these will
  again fail on select/poll errors different than EINTR.

Daniel Fandrich (5 Mar 2008)
- Fixed the test harness so it will write out zero-length data files.

- Added tests 616 and 617 to see how SFTP and SCP cope with zero-length
  files, as questioned by Mike Protts. SFTP does for me but SCP doesn't
  so test 617 is disabled for now.

Daniel S (4 Mar 2008)
- Mike Protts brought a patch that makes resumed transfers work with SFTP.

Daniel S (1 Mar 2008)
- Anatoli Tubman found and fixed a crash with Negotiate authentication used on
  a re-used connection where both requests used Negotiate.

Guenter Knauf (26 Feb 2008)
- Kaspar Brand provided a patch to support server name indication (RFC 4366).

Daniel S (25 Feb 2008)
- Kaspar Brand made GnuTLS-built libcurl properly acknowledge the option that
  forces it to prefer SSLv3.

Daniel S (23 Feb 2008)
- Sam Listopad provided a patch in feature-request #1900014
  https://curl.haxx.se/bug/feature.cgi?id=1900014 that makes libcurl (built to
  use OpenSSL) support a full chain of certificates in a given PKCS12
  certificate.

Daniel S (22 Feb 2008)
- Georg Lippitsch made the src/Makefile.vc6 makefile use the same memory model
  options as the lib/Makefile.vc6 already did.

Daniel S (21 Feb 2008)
- Zmey Petroff found a crash when libcurl accessed a NULL pointer, which
  happened if you set the connection cache size to 1 and for example failed to
  login to an FTP site. Bug report #1896698
  (https://curl.haxx.se/bug/view.cgi?id=1896698)

Daniel S (20 Feb 2008)
- Fixed test case 405 to not fail when libcurl is built with GnuTLS

- Based on initial work done by Gautam Kachroo to address a bug, we now keep
  better control at the exact state of the connection's SSL status so that we
  know exactly when it has completed the SSL negotiation or not so that there
  won't be accidental re-uses of connections that are wrongly believed to be
  in SSL-completed-negotiate state.

- We no longer support setting the CURLOPT_URL option from inside a callback
  such as the CURLOPT_SSL_CTX_FUNCTION one treat that as if it was a Location:
  following. The patch that introduced this feature was done for 7.11.0, but
  this code and functionality has been broken since about 7.15.4 (March 2006)
  with the introduction of non-blocking OpenSSL "connects".

  It was a hack to begin with and since it doesn't work and hasn't worked
  correctly for a long time and nobody has even noticed, I consider it a very
  suitable subject for plain removal. And so it was done.

Guenter Knauf (19 Feb 2008)
- We do no longer support SSLv2 by default since it has known flaws.
  Kaspar Brand provided a patch for all supported SSL toolkits.

Daniel Fandrich (19 Feb 2008)
- Added test309 to test HTTP redirect to HTTPS URL

Daniel S (18 Feb 2008)
- We're no longer providing a very old ca-bundle in the curl tarball. You can
  get a fresh one downloaded and created with 'make ca-bundle' or you can get
  one from here => https://curl.haxx.se/docs/caextract.html if you want a fresh
  new one extracted from Mozilla's recent list of ca certs.

  The configure option --with-ca-bundle now lets you specify what file to use
  as default ca bundle for your build. If not specified, the configure script
  will check a few known standard places for a global ca cert to use.

Daniel S (17 Feb 2008)
- Jerome Muffat-Meridol helped me fix Curl_done() to close the current
  connection by force when it was called before the entire request is
  completed, simply because we can't know if the connection really can be
  re-used safely at that point.

- Based on the same debugging logic, I've also made Curl_http_done() not
  return CURLE_GOT_NOTHING if called "prematurely". This should have no real
  effect to anything but the code makes more sense like this.

Daniel S (15 Feb 2008)
- Made the gnutls code path not even try to get the server cert if no peer
  verification is requested. Previously it would even return failure if gnutls
  failed to get the server cert even though no verification was asked for.
  Public server showing the problem: https://www.net222.caisse-epargne.fr

- Fix my Curl_timeleft() leftover mistake in the gnutls code

- Pooyan McSporran found and fixed a flaw where you first would do a normal
  http request and then you'd reuse the handle and replace the Accept: header,
  as then libcurl would send two Accept: headers!

Daniel S (11 Feb 2008)
- Yang Tse pointed out a few remaining quirks from my timeout refactoring from
  Feb 7 that didn't abort properly on timeouts. These are actually old
  problems but now they should be fixed.

Yang Tse (10 Feb 2008)
- Bug report #1888932 (https://curl.haxx.se/bug/view.cgi?id=1888932) points out
  and provides test program that demonstrates that libcurl might not set error
  description message for error CURLE_COULDNT_RESOLVE_HOST for Windows threaded
  name resolver builds. Fixed now.

Daniel Fandrich (8 Feb 2008)
- Added key words to all SSL-using tests so they can be skipped if necessary.
  Removed a few unnecessary requires SSL statements.

Daniel S (8 Feb 2008)
- Mike Hommey filed and fixed bug report #1889856
  (https://curl.haxx.se/bug/view.cgi?id=1889856): When using the gnutls ssl
  layer, cleaning-up and reinitializing curl ends up with https requests
  failing with "ASN1 parser: Element was not found" errors. Obviously a
  regression added in 7.16.3.

Yang Tse (8 Feb 2008)
- Improved test harness SCP/SFTP start up server verification, doing a real
  connection to the sftp server, authenticating and running a simple sftp
  pwd command using the test harness generated configuration and key files.

Daniel S (8 Feb 2008)
- Günter Knauf added lib/mk-ca-bundle.pl which gets the Firefox ca bundle and
  creates a suitable ca-bundle.crt file in PEM format for use with curl. The
  recommended way to run it is to use 'make ca-bundle' in the build tree root.

Daniel Fandrich (7 Feb 2008)
- Added tests 1022 and 1023 to validate output of curl-config --version and
  --vernum

Daniel S (7 Feb 2008)
- Refactored a lot of timeout code into a few functions in an attempt to make
  them all use the same (hopefully correct) logic to make it less error-prone
  and easier to introduce library-wide where it should be used.

Yang Tse (6 Feb 2008)
- Fix an issue in strdup replacement function when dealing with absolutely
  huge strings. Only systems without a standard strdup would be affected.

Daniel S (3 Feb 2008)
- Dmitry Kurochkin cleaned up the pipelining code and removed the need for and
  use of the "is_in_pipeline" struct field.

- I wrote up and added the threaded-ssl.c example source code that shows how
  to do multi-threaded downloads of HTTPS files with a libcurl that is built
  with OpenSSL. It uses pthreads for the threading.

Daniel S (31 Jan 2008)
- Niklas Angebrand made the cookie support in libcurl properly deal with the
  "HttpOnly" feature introduced by Microsoft and apparently also supported by
  Firefox: https://msdn.microsoft.com/en-us/library/ms533046.aspx . HttpOnly
  is now supported when received from servers in HTTP headers, when written to
  cookie jars and when read from existing cookie jars.

  I modified test case 31 and 46 to also do some basic HttpOnly testing.

- Dmitry Kurochkin moved several struct fields from the connectdata struct to
  the SingleRequest one to make pipelining better. It is a bit tricky to keep
  them in the right place, to keep things related to the actual request or to
  the actual connection in the right place.

Daniel S (29 Jan 2008)
- Dmitry Kurochkin fixed Curl_done() for pipelining, as it could previously
  crash!

- Michal Marek fixed minor mistake in test case 553 that prevented it from
  working on other IP-addresses or port numbers.

Version 7.18.0 (28 January 2008)

Daniel S (27 Jan 2008)
- Dmitry Kurochkin: In "real world" testing I found more bugs in
  pipelining. Broken connection is not restored and we get into infinite
  loop. It happens because of wrong is_in_pipeline values.

Daniel S (26 Jan 2008)
- Kevin Reed filed bug report #1879375
  (https://curl.haxx.se/bug/view.cgi?id=1879375) which describes how libcurl
  got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
  proxy authentication and the proxy replies with an auth (like NTLM) and then
  closes the connection after that initial informational response.

  libcurl would not properly re-initialize the connection to the proxy and
  continue the auth negotiation like supposed. It does now however, as it will
  now detect if one or more authentication methods were available and asked
  for, and will thus retry the connection and continue from there.

- I made the progress callback get called properly during proxy CONNECT.

Daniel S (23 Jan 2008)
- Igor Franchuk pointed out that CURLOPT_COOKIELIST set to "ALL" leaked
  memory, and so did "SESS". Fixed now.

Yang Tse (22 Jan 2008)
- Check poll.h at configuration time, and use it when sys/poll.h unavailable

Daniel S (22 Jan 2008)
- Dmitry Kurochkin removed the cancelled state for pipelining, as we agreed
  that it is bad anyway. Starting now, removing a handle that is in used in a
  pipeline will break the pipeline - it'll be set back up again but still...

Yang Tse (21 Jan 2008)
- Disable ldap support for cygwin builds, since it breaks whole build process.
  Fixing it will affect other platforms, so it is postponed for another release.

Daniel S (18 Jan 2008)
- Lau Hang Kin found and fixed a problem with the multi interface when doing
  CONNECT over a proxy. curl_multi_fdset() didn't report back the socket
  properly during that state, due to a missing case in the switch in the
  multi_getsock() function.

Yang Tse (17 Jan 2008)
- Don't abort tests 518 and 537 when unable to raise the open-file soft limit.

Daniel S (16 Jan 2008)
- Nathan Coulter's patch that makes runtests.pl respect the PATH when figuring
  out what valgrind to run.

Yang Tse (16 Jan 2008)
- Improved handling of out of memory in the command line tool that afected
  data url encoded HTTP POSTs when reading it from a file.

Daniel S (16 Jan 2008)
- Dmitry Kurochkin worked a lot on improving the HTTP Pipelining support that
  previously had a number of flaws, perhaps most notably when an application
  fired up N transfers at once as then they wouldn't pipeline at all that
  nicely as anyone would think... Test case 530 was also updated to take the
  improved functionality into account.

- Calls to Curl_failf() are not supposed to provide a trailing newline as the
  function itself adds that. Fixed on 50 or something strings!

Daniel S (15 Jan 2008)
- I made the torture test on test 530 go through. This was actually due to
  silly code left from when we switched to let the multi handle "hold" the dns
  cache when using the multi interface... Of course this only triggered when a
  certain function call returned error at the correct moment.

Daniel S (14 Jan 2008)
- Joe Malicki filed bug report #1871269
  (https://curl.haxx.se/bug/view.cgi?id=1871269) and we could fix his hang-
  problem that occurred when doing a large HTTP POST request with the
  response-body read from a callback.

Daniel S (12 Jan 2008)
- I re-arranged the curl --help output. All the options are now sorted on
  their long option names and all descriptions are one-liners.

- Eric Landes provided the patch (edited by me) that introduces the
  --keepalive-time to curl to set the keepalive probe interval. I also took
  the opportunity to rename the recently added no-keep-alive option to
  no-keepalive to keep a consistent naming and to avoid getting two dashes in
  these option names. Eric also provided an update to the man page for the new
  option.

Daniel S (11 Jan 2008)
- Daniel Egger made CURLOPT_RANGE work on file:// URLs the very same way it
  already worked for FTP:// URLs.

- I made the curl tool switch from using CURLOPT_IOCTLFUNCTION to now use the
  spanking new CURLOPT_SEEKFUNCTION simply to take advantage of the improved
  performance for the upload resume cases where you want to upload the last
  few bytes of a very large file. To implement this decently, I had to switch
  the client code for uploading from fopen()/fread() to plain open()/read() so
  that we can use lseek() to do >32bit seeks (as fseek() doesn't allow that)
  on systems that offer support for that.

Daniel S (10 Jan 2008)
- Michal Marek made curl-config --libs not include /usr/lib64 in the output
  (it already before skipped /usr/lib).  /usr/lib64 is the default library
  directory on many 64bit systems and it's unlikely that anyone would use the
  path privately on systems where it's not.

- Georg Lippitsch brought CURLOPT_SEEKFUNCTION and CURLOPT_SEEKDATA to allow
  libcurl to seek in a given input stream. This is particularly important when
  doing upload resumes when there's already a huge part of the file present
  remotely. Before, and still if this callback isn't used, libcurl will read
  and through away the entire file up to the point to where the resuming
  begins (which of course can be a slow opereration depending on file size,
  I/O bandwidth and more). This new function will also be preferred to get
  used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
  doing multi-stage HTTP auth with POST/PUT.

- Nikitinskit Dmitriy filed bug report #1868255
  (https://curl.haxx.se/bug/view.cgi?id=1868255) with a patch. It identifies
  and fixes a problem with parsing WWW-Authenticate: headers with additional
  spaces in the line that the parser wasn't written to deal with.

Daniel S (8 Jan 2008)
- Introducing curl_easy_pause() and new magic return codes for both the read
  and the write callbacks that now can make a connection's reading and/or
  writing get paused.

Daniel S (6 Jan 2008)
- Jeff Johnson filed bug report #1863171
  (https://curl.haxx.se/bug/view.cgi?id=1863171) where he pointed out that
  libcurl's date parser didn't accept a +1300 time zone which actually is used
  fairly often (like New Zealand's Dailight Savings Time), so I modified the
  parser to now accept up to and including -1400 to +1400.

Daniel S (5 Jan 2008)
- Based on further discussion on curl-library, I reverted yesterday's SOCKS5
  code to instead introduce support for a new proxy type called
  CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
  instead of IP address and there's thus no longer any need for a new
  curl_easy_setopt() option.

  The default SOCKS5 proxy is again back to sending the IP address to the
  proxy.  The new curl command line option for enabling sending host name to a
  SOCKS5 proxy is now --socks5-hostname.

Daniel S (4 Jan 2008)
- Based on Maxim Perenesenko's patch, we now do SOCKS5 operations and let the
  proxy do the host name resolving and only if --socks5ip (or
  CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
  pass on the IP address only to the proxy.

Yang Tse (3 Jan 2008)
- Modified test harness to allow SCP, SFTP and SOCKS4 tests to run with
  OpenSSH 2.9.9, SunSSH 1.0 or later versions. SOCKS5 tests need OpenSSH
  3.7, SunSSH 1.0 or later.

Daniel S (2 Jan 2008)
- I fixed two cases of missing return code checks when handling chunked
  decoding where a write error (or abort return from a callback) didn't stop
  libcurl's processing.

- I removed the socklen_t use from the public curl/curl.h header and instead
  made it an unsigned int. The type was only used in the curl_sockaddr struct
  definition (only used by the curl_opensocket_callback). On all platforms I
  could find information about, socklen_t is 32 unsigned bits large so I don't
  think this will break the API or ABI. The main reason for this change is of
  course for all the platforms that don't have a socklen_t definition in their
  headers to build fine again. Providing our own configure magic and custom
  definition of socklen_t on those systems proved to work but was a lot of
  cruft, code and extra magic needed - when this very small change of type
  seems harmless and still solves the missing socklen_t problem.

- Richard Atterer brought a patch that added support for SOCKS4a proxies,
  which is an inofficial PROXY4 variant that sends the hostname to the proxy
  instead of the resolved address (which is already supported by SOCKS5).
  --socks4a is the curl command line option for it and CURLOPT_PROXYTYPE can
  now be set to CURLPROXY_SOCKS4A as well.

Daniel S (1 Jan 2008)
- Mohun Biswas pointed out that --libcurl generated a source code with an int
  function but without a return statement. While fixing that, I also took care
  about adding some better comments for the generated code.

Daniel S (27 Dec 2007)
- Dmitry Kurochkin mentioned a flaw
  (https://curl.haxx.se/mail/lib-2007-12/0252.html) in detect_proxy() which
  failed to set the bits.proxy variable properly when an environment variable
  told libcurl to use a http proxy.

Daniel S (26 Dec 2007)
- In an attempt to repeat the problem in bug report #1850730
  (https://curl.haxx.se/bug/view.cgi?id=1850730) I wrote up test case 552. The
  test is doing a 70K POST with a read callback and an ioctl callback over a
  proxy requiring Digest auth. The test case code is more or less identical to
  the test recipe code provided by Spacen Jasset (who submitted the bug
  report).

Daniel S (25 Dec 2007)
- Gary Maxwell filed bug report #1856628
  (https://curl.haxx.se/bug/view.cgi?id=1856628) and provided a fix for the
  (small) memory leak in the SSL session ID caching code. It happened when a
  previous entry in the cache was re-used.

Daniel Fandrich (19 Dec 2007)
- Ensure that nroff doesn't put anything but ASCII characters into the
  --manual text.

Yang Tse (18 Dec 2007)
- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
  and makes wrong asumptions of build target when it isn't specified. So,
  if no build target has been defined we will target WinXP when building
  curl/libcurl with MSVC 9.0 (VS2008).

- (https://curl.haxx.se/mail/archive-2007-12/0039.html) reported and fixed
  a file truncation problem on Windows build targets triggered when retrying
  a download with curl.

Daniel S (17 Dec 2007)
- Mateusz Loskot pointed out that MSVC 9.0 (VS2008) has the pollfd struct and
  defines in winsock2.h somehow differently than previous versions and that
  curl 7.17.1 would fail to compile out of the box.

Daniel S (13 Dec 2007)
- David Wright filed bug report #1849764
  (https://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He
  identified a problem for re-used connections that previously had sent
  Expect: 100-continue and in some situations the subsequent POST (that didn't
  use Expect:) still had the internal flag set for its use. David's fix (that
  makes the setting of the flag in every single request unconditionally) is
  fine and is now used!

Daniel S (12 Dec 2007)
- Gilles Blanc made the curl tool enable SO_KEEPALIVE for the connections and
  added the --no-keep-alive option that can disable that on demand.

Daniel S (9 Dec 2007)
- Andrew Moise filed bug report #1847501
  (https://curl.haxx.se/bug/view.cgi?id=1847501) and pointed out a memcpy()
  that should be memmove() in the convert_lineends() function.

Daniel S (8 Dec 2007)
- Renamed all internal static functions that had Curl_ prefixes to no longer
  have them. The Curl_ prefix is exclusively used for library internal global
  symbols. Static functions can be named anything, except for using Curl_ or
  curl_ prefixes. This is for consistency and for easier maintainance and
  overview.

- Cleaned up and reformatted the TODO document to look like the FAQ and
  CONTRIBUTE, which makes nicer web pages

- Added test cases 549 and 550 that test CURLOPT_PROXY_TRANSFER_MODE.

- Added keywords on a bunch of test cases

- Fixed an OOM problem in the curl code that would lead to fclose on a bad
  handle and crash

Daniel S (5 Dec 2007)
- Spacen Jasset reported a problem with doing POST (with data read with a
  callback) over a proxy when NTLM is used as auth with the proxy. The bug
  also concerned Digest and was limited to using callback only. Spacen worked
  with us to provide a useful patch. I added the test case 547 and 548 to
  verify two variations of POST over proxy with NTLM.

Daniel S (3 Dec 2007)
- Ray Pekowski filed bug report #1842029
  (https://curl.haxx.se/bug/view.cgi?id=1842029) in which he identified a
  problem with SSL session caching that prevent it from working, and provided
  the associated fix!

- Now libcurl (built with OpenSSL) doesn't return error anymore if the remote
  SSL-based server doesn't present a certificate when the request is told to
  ignore certificate verification anyway.

- Michal Marek introduced CURLOPT_PROXY_TRANSFER_MODE which is used to control
  the appending of the "type=" thing on FTP URLs when they are passed to a
  HTTP proxy. Some proxies just don't like that appending (which is done
  unconditionally in 7.17.1), and some proxies treat binary/ascii transfers
  better with the appending done!

Daniel S (29 Nov 2007)
- A bug report on the curl-library list showed a HTTP Digest session going on
  with a 700+ letter nonce. Previously libcurl only support 127 letter ones
  and now I bumped it to 1023.

- Fixed the resumed FTP upload loop to not require that the read callback
  returns a full buffer on each invoke.

Daniel S (25 Nov 2007)
- Added test case 1015 that tests --data-urlencode in multiple ways

- Fixed --data-urlencode for when no @ or = are used

- Extended the user-agent buffer curl uses, since we can hit the 128 byte
  border with plenty development libraries used. Like my current set: "curl
  7.17.2-CVS (i686-pc-linux-gnu) libcurl/7.17.2-CVS OpenSSL/0.9.8g
  zlib/1.2.3.3 c-ares/1.5.2-CVS libidn/1.1 libssh2/0.19.0-CVS"

Daniel S (24 Nov 2007)
- Internal rearrangements, so that the previous struct HandleData is no more.
  It is now known as SingleRequest and the Curl_transfer_keeper struct within
  that was remove entirely. This has the upside that there are less duplicate
  struct members that made it hard to see and remember what struct that was
  used to store what data. The transfer_keeper thing was once stored on a
  per-connection basis and then it made sense to have the duplicate info but
  since it was moved to the SessionHandle (in 7.16.0) it just added weirdness.
  The SingleRequest struct is used by data that only is valid for this single
  request.

Yang Tse (22 Nov 2007)
- Provide a socklen_t definition in curl.h for Win32 API build targets
  which don't have one.

Daniel S (22 Nov 2007)
- Alessandro Vesely helped me improve the --data-urlencode's syntax, parser
  and documentation.

Daniel S (21 Nov 2007)
- While inspecting the Negotiate code, I noticed how the proxy auth was using
  the same state struct as the host auth, so both could never be used at the
  same time! I fixed it (without being able to check) to use two separate
  structs to allow authentication using Negotiate on host and proxy
  simultaneously.

Daniel S (20 Nov 2007)
- Emil Romanus pointed out a bug that made an easy handle get the cookie
  engine activated when set to use a share (even if the share doesn't share
  cookies). I fixed it.

- Fixed a very long-lasting mprintf() bug that occurred when we did "%.*s%s",
  since the second %s would then wrongly used the numerical precision argument
  instead and crash.

- Introduced --data-urlencode to the curl tool for easier url encoding of the
  data sent in a post.

Daniel S (18 Nov 2007)
- Rob Crittenden fixed SSL connections with NSS done with the multi-interface

Daniel S (17 Nov 2007)
- Michal Marek made the test suite remember what test servers that fail to
  start so that subsequent tries are simply skipped.

- Andres Garcia made the examples build fine on Windows (mingw + msys) when
  the lib was built staticly.

Daniel S (16 Nov 2007)
- Ates Goral identified a problem in http.c:add_buffer_send() when a debug
  callback was used, as it could wrongly pass on a bad size for the outgoing
  HTTP header. The bad size would be a very large value as it was a wrapped
  size_t content. This happened when the whole HTTP request failed to get sent
  in one single send.  https://curl.haxx.se/mail/lib-2007-11/0165.html

Daniel S (15 Nov 2007)
- Fixed yet another remaining problem with doing SFTP directory listings on a
  re-used persistent connection. Mentioned by Immanuel Gregoire on the mailing
  list.

- Michal Marek fixed the test suite to better deal with the case when the HTTP
  IPv6 server can't run.

Yang Tse (14 Nov 2007)
- Fix a variable potential wrapping in add_buffer() when using absolutely
  huge send buffer sizes.

Daniel S (13 Nov 2007)
- Fixed a remaining problem with doing SFTP directory listings on a re-used
  persistent connection. Mentioned by Immanuel Gregoire on the mailing list.

Daniel S (12 Nov 2007)
- Bug report #1830637 (https://curl.haxx.se/bug/view.cgi?id=1830637), which was
  forwarded from the Gentoo bug tracker by Daniel Black and was originally
  submitted by Robin Johnson, pointed out that libcurl would do bad memory
  references when it failed and bailed out before the handler thing was
  setup. My fix is not done like the provided patch does it, but instead I
  make sure that there's never any chance for a NULL pointer in that struct
  member.

Yang Tse (10 Nov 2007)
- Vikram Saxena (https://curl.haxx.se/mail/lib-2007-11/0096.html) pointed out
  that the pollfd struct was being multi defined when using VS2008. This is
  now fixed in /curl/lib/select.h

Daniel S (8 Nov 2007)
- Bug report #1823487 (https://curl.haxx.se/bug/view.cgi?id=1823487) pointed
  out that SFTP requests didn't use persistent connections. Neither did SCP
  ones.  I gave the SSH code a good beating and now both SCP and SFTP should
  use persistent connections fine. I also did a bunch of indent changes as
  well as a bug fix for the "keyboard interactive" auth.

Dan F (6 Nov 2007)
- Improved telnet support by drastically reducing the number of write
  callbacks needed to pass a buffer to the user.  Instead one per byte it
  is now as little as one per segment.

Yang Tse (6 Nov 2007)
- Bug report #1824894 (https://curl.haxx.se/bug/view.cgi?id=1824894) pointed
  out a problem in curl.h when building C++ apps with MSVC. To fix it, the
  inclusion of header files in curl.h is moved outside of the C++ extern "C"
  linkage block.

Daniel S (1 Nov 2007)
- Toby Peterson patched a memory problem in the command line tool that
  happened when a user had a home dir as an empty string. curl would then do
  free() on a wrong area.

Dan F (1 Nov 2007)
- Fixed curl-config --features to not display libz when it wasn't used
  due to a missing header file.

Dan F (31 October 2007)
- Fixed the output of curl-config --protocols which showed SCP and SFTP
  always, except when --without-libssh2 was given

- Added test cases 1013 and 1014 to check that curl-config --protocols and
  curl-config --features matches the output of curl --version

Dan F (30 October 2007)
- Fixed an OOM problem with file: URLs

- Moved Curl_file_connect into the protocol handler struct

Dan F (29 October 2007)
- Added test case 546 to check that subsequent FTP transfers work after a
  failed one using the multi interface

Daniel S (29 October 2007)
- Based on one of those bug reports that are intercepted by a distro's bug
  tracker (https://bugzilla.redhat.com/show_bug.cgi?id=316191), I now made
  curl-config --features and --protocols show the correct output when built
  with NSS.

Version 7.17.1 (29 October 2007)

Dan F (25 October 2007)
- Added the --static-libs option to curl-config

Daniel S (25 October 2007)
- Made libcurl built with NSS possible to ignore the peer verification.
  Previously it would fail if the ca bundle wasn't present, even if the code
  ignored the verification results.

Patrick M (25 October 2007)
- Fixed test server to allow null bytes in binary posts.
_ Added tests 35, 544 & 545 to check binary data posts, both static (in place)
  and dynamic (copied).

Daniel S (25 October 2007)
- Michal Marek fixed the test script to be able to use valgrind even when the
  lib is built shared with libtool.

- Fixed a few memory leaks when the same easy handle is re-used to request
  URLs with different protocols. FTP and TFTP related leaks. Caught thanks to
  Dan F's new test cases.

Dan F (24 October 2007)
- Fixed the test FTP and TFTP servers to support the >10000 test number
  notation

- Added test cases 2000 through 2003 which test multiple protocols using the
  same easy handle

- Fixed the filecheck: make target to work outside the source tree

Daniel S (24 October 2007)
- Vladimir Lazarenko pointed out that we should do some 'mt' magic when
  building with VC8 to get the "manifest" embedded to make fine stand-alone
  binaries. The maketgz and the src/Makefile.vc6 files were adjusted
  accordingly.

Daniel S (23 October 2007)
- Bug report #1812190 (https://curl.haxx.se/bug/view.cgi?id=1812190) points out
  that libcurl tried to re-use connections a bit too much when using non-SSL
  protocols tunneled over a HTTP proxy.

Daniel S (22 October 2007)
- Michal Marek forwarded the bug report
  https://bugzilla.novell.com/show_bug.cgi?id=332917 about a HTTP redirect to
  FTP that caused memory havoc. His work together with my efforts created two
  fixes:

  #1 - FTP::file was moved to struct ftp_conn, because is has to be dealt with
       at connection cleanup, at which time the struct HandleData could be
       used by another connection.
       Also, the unused char *urlpath member is removed from struct FTP.

  #2 - provide a Curl_reset_reqproto() function that frees
       data->reqdata.proto.* on connection setup if needed (that is if the
       SessionHandle was used by a different connection).

  A long-term goal is of course to somehow get rid of how the reqdata struct
  is used, as it is too error-prone.

- Bug report #1815530 (https://curl.haxx.se/bug/view.cgi?id=1815530) points out
  that specifying a proxy with a trailing slash didn't work (unless it also
  contained a port number).

Patrick M (15 October 2007)
- Fixed the dynamic CURLOPT_POSTFIELDS problem: this option is now static again
  and option CURLOPT_COPYPOSTFIELDS has been added to support dynamic mode.

Patrick M (12 October 2007)
- Added per-protocol callback static tables, replacing callback ptr storage
  in the connectdata structure by a single handler table ptr.

Dan F (11 October 2007)
- Fixed the -l option of runtests.pl

- Added support for skipping tests based on key words.

Daniel S (9 October 2007)
- Michal Marek removed the no longer existing return codes from the curl.1
  man page.

Daniel S (7 October 2007)
- Known bug #47, which confused libcurl if doing NTLM auth over a proxy with
  a response that was larger than 16KB is now improved slightly so that now
  the restriction at 16KB is for the headers only and it should be a rare
  situation where the response-headers exceed 16KB. Thus, I consider #47 fixed
  and the header limitation is now known as known bug #48.

Daniel S (5 October 2007)
- Michael Wallner made the CULROPT_COOKIELIST option support a new magic
  string: "FLUSH". Using that will cause libcurl to flush its cookies to the
  CURLOPT_COOKIEJAR file.

- The new file docs/libcurl/ABI describes how we view ABI breakages, soname
  bumps and what the version number's significance to all that is.

Daniel S (4 October 2007)
- I enabled test 1009 and made the --local-port use a wide range to reduce the
  risk of failures.

- Kim Rinnewitz reported that --local-port didn't work with TFTP transfers.
  This happened because the tftp code always uncondionally did a bind()
  without caring if one already had been done and then it failed. I wrote a
  test case (1009) to verify this, but it is a bit error-prone since it will
  have to pick a fixed local port number and since the tests are run on so
  many different hosts in different situations I'll add it in disabled state.

Yang Tse (3 October 2007)
- Fixed issue related with the use of ares_timeout() result.

Daniel S (3 October 2007)
- Alexey Pesternikov introduced CURLOPT_OPENSOCKETFUNCTION and
  CURLOPT_OPENSOCKETDATA to set a callback that allows an application to
  replace the socket() call used by libcurl. It basically allows the app to
  change address, protocol or whatever of the socket.

- I renamed the CURLE_SSL_PEER_CERTIFICATE error code to
  CURLE_PEER_FAILED_VERIFICATION (standard CURL_NO_OLDIES style), and made
  this return code get used by the previous SSH MD5 fingerprint check in case
  it fails.

- Based on a patch brought by Johnny Luong, libcurl now offers
  CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 and the curl tool --hostpubmd5. They both
  make the SCP or SFTP connection verify the remote host's md5 checksum of the
  public key before doing a connect, to reduce the risk of a man-in-the-middle
  attack.

Daniel S (2 October 2007)
- libcurl now handles chunked-encoded CONNECT responses

Daniel S (1 October 2007)
- Alex Fishman reported a curl_easy_escape() problem that was made the
  function do wrong on all input bytes that are >= 0x80 (decimal 128) due to a
  signed / unsigned mistake in the code. I fixed it and added test case 543 to
  verify.

Daniel S (29 September 2007)
- Immanuel Gregoire fixed a problem with persistent transfers over SFTP.

Daniel S (28 September 2007)
- Adapted the c-ares code to the API change c-ares 1.5.0 brings in the
  notifier callback(s).

Dan F (26 September 2007)
- Enabled a few more gcc warnings with --enable-debug.  Renamed a few
  variables to avoid shadowing global declarations.

Daniel S (26 September 2007)
- Philip Langdale provided the new CURLOPT_POST301 option for
  curl_easy_setopt() that alters how libcurl functions when following
  redirects. It makes libcurl obey the RFC2616 when a 301 response is received
  after a non-GET request is made. Default libcurl behaviour is to change
  method to GET in the subsequent request (like it does for response code 302
  - because that's what many/most browsers do), but with this CURLOPT_POST301
  option enabled it will do what the spec says and do the next request using
  the same method again. I.e keep POST after 301.

  The curl tool got this option as --post301

  Test case 1011 and 1012 were added to verify.

- Max Katsev reported that when doing a libcurl FTP request with
  CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE
  before it does SIZE which makes it less useful. I walked over the code and
  made it do this properly, and added test case 542 to verify it.

Daniel S (24 September 2007)
- Immanuel Gregoire fixed KNOWN_BUGS #44: --ftp-method nocwd did not handle
  URLs ending with a slash properly (it should list the contents of that
  directory). Test case 351 brought back and also test 1010 was added.

Daniel S (21 September 2007)
- Mark Davies fixed Negotiate authentication over proxy, and also introduced
  the --proxy-negotiate command line option to allow a user to explicitly
  select it.

Daniel S (19 September 2007)
- Rob Crittenden provided an NSS update with the following highlights:

  o It looks for the NSS database first in the environment variable SSL_DIR,
    then in /etc/pki/nssdb, then it initializes with no database if neither of
    those exist.

  o If the NSS PKCS#11 libnspsem.so driver is available then PEM files may be
    loaded, including the ca-bundle. If it is not available then only
    certificates already in the NSS database are used.

  o Tries to detect whether a file or nickname is being passed in so the right
    thing is done

  o Added a bit of code to make the output more like the OpenSSL module,
    including displaying the certificate information when connecting in
    verbose mode

  o Improved handling of certificate errors (expired, untrusted, etc)

  The libnsspem.so PKCS#11 module is currently only available in Fedora
  8/rawhide. Work will be done soon to upstream it. The NSS module will work
  with or without it, all that changes is the source of the certificates and
  keys.

Daniel S (18 September 2007)
- Immanuel Gregoire pointed out that public key SSH auth failed if no
  public/private key was specified and there was no HOME environment variable,
  and then it didn't continue to try the other auth methods. Now it will
  instead try to get the files id_dsa.pub and id_dsa from the current
  directory if none of the two conditions were met.

Dan F (17 September 2007)
- Added hooks to the test suite to make it possible to test a curl running
  on a remote host.

- Changed some FTP tests to validate the format of the PORT and EPRT commands
  sent by curl, if not the addresses themselves.

Daniel S (15 September 2007)
- Michal Marek made libcurl automatically append ";type=<a|i>" when using HTTP
  proxies for FTP urls.

- Günter Knauf fixed LDAP builds in the Windows makefiles and fixed LDAPv3
  support on Windows.

Dan F (13 September 2007)
- Added LDAPS, SCP and SFTP to curl-config --protocols. Removed and
  fixed some AC_SUBST configure entries.

Version 7.17.0 (13 September 2007)

Daniel S (12 September 2007)
- Bug report #1792649 (https://curl.haxx.se/bug/view.cgi?id=1792649) pointed
  out a problem with doing an empty upload over FTP on a re-used connection.
  I added test case 541 to reproduce it and to verify the fix.

- I noticed while writing test 541 that the FTP code wrongly did a CWD on the
  second transfer as it didn't store and remember the "" path from the
  previous transfer so it would instead CWD to the entry path as stored. This
  worked, but did a superfluous command. Thus, test case 541 now also verifies
  this fix.

Dan F (5 September 2007)
- Added test case 1007 to test permission problem when uploading with TFTP
  (to validate bug #1790403).

- TFTP now reports the "not defined" TFTP error code 0 as an error,
  not success.

Daniel S (5 September 2007)
- Continued the work on a fix for #1779054
  (https://curl.haxx.se/bug/view.cgi?id=1779054). My previous fix from August
  24 was not complete (either) but could accidentally "forget" parts of a
  server response which led to faulty server response time-out errors.

Dan F (5 September 2007)
- Minix doesn't support getsockopt on UDP sockets or send/recv on TCP
  sockets.

Dan F (31 August 2007)
- Made some of the error strings returned by the *strerror functions more
  generic, and more consistent with each other.

- Renamed the curl_ftpssl enum to curl_usessl and its enumerated constants,
  creating macros for backward compatibility:

    CURLFTPSSL_NONE => CURLUSESSL_NONE
    CURLFTPSSL_TRY => CURLUSESSL_TRY
    CURLFTPSSL_CONTROL => CURLUSESSL_CONTROL
    CURLFTPSSL_ALL => CURLUSESSL_ALL
    CURLFTPSSL_LAST => CURLUSESSL_LAST

Dan F (30 August 2007)
- Renamed several libcurl error codes and options to make them more general
  and allow reuse by multiple protocols. Several unused error codes were
  removed.  In all cases, macros were added to preserve source (and binary)
  compatibility with the old names.  These macros are subject to removal at
  a future date, but probably not before 2009.  An application can be
  tested to see if it is using any obsolete code by compiling it with the
  CURL_NO_OLDIES macro defined.

  The following unused error codes were removed:

    CURLE_BAD_CALLING_ORDER
    CURLE_BAD_PASSWORD_ENTERED
    CURLE_FTP_CANT_RECONNECT
    CURLE_FTP_COULDNT_GET_SIZE
    CURLE_FTP_COULDNT_SET_ASCII
    CURLE_FTP_USER_PASSWORD_INCORRECT
    CURLE_FTP_WEIRD_USER_REPLY
    CURLE_FTP_WRITE_ERROR
    CURLE_LIBRARY_NOT_FOUND
    CURLE_MALFORMAT_USER
    CURLE_OBSOLETE
    CURLE_SHARE_IN_USE
    CURLE_URL_MALFORMAT_USER

  The following error codes were renamed:

    CURLE_FTP_ACCESS_DENIED =>      CURLE_REMOTE_ACCESS_DENIED
    CURLE_FTP_COULDNT_SET_BINARY => CURLE_FTP_COULDNT_SET_TYPE
    CURLE_FTP_SSL_FAILED =>         CURLE_USE_SSL_FAILED
    CURLE_FTP_QUOTE_ERROR =>        CURLE_QUOTE_ERROR
    CURLE_TFTP_DISKFULL =>          CURLE_REMOTE_DISK_FULL
    CURLE_TFTP_EXISTS =>            CURLE_REMOTE_FILE_EXISTS
    CURLE_HTTP_RANGE_ERROR =>       CURLE_RANGE_ERROR

  The following options were renamed:

    CURLOPT_SSLKEYPASSWD => CURLOPT_KEYPASSWD
    CURLOPT_FTPAPPEND =>    CURLOPT_APPEND
    CURLOPT_FTPLISTONLY =>  CURLOPT_DIRLISTONLY
    CURLOPT_FTP_SSL =>      CURLOPT_USE_SSL

  A few more changes will take place with the next SONAME bump of the
  library.  These are documented in docs/TODO

- Documented some newer error codes in libcurl-error(3)

- Added more accurate error code returns from SFTP operations.  Added test
  case 615 to test an SFTP upload failure.

Dan F (28 August 2007)
- Some minor internal type and const changes based on a splint scan.

Daniel S (24 August 2007)
- Bug report #1779054 (https://curl.haxx.se/bug/view.cgi?id=1779054) pointed
  out that libcurl didn't deal with large responses from server commands, when
  the single response was consisting of multiple lines but of a total size of
  16KB or more. Dan Fandrich improved the ftp test script and provided test
  case 1006 to repeat the problem, and I fixed the code to make sure this new
  test case runs fine.

Patrick M (23 August 2007)
- OS/400 port: new files lib/config-os400.h lib/setup-os400.h packages/OS400/*.
  See packages/OS400/README.OS400.

Daniel S (23 August 2007)
- Bug report #1779751 (https://curl.haxx.se/bug/view.cgi?id=1779751) pointed
  out that doing first a file:// upload and then an FTP upload crashed libcurl
  or at best caused furious valgrind complaints. Fixed now!

Daniel S (22 August 2007)
- Bug report #1779054 (https://curl.haxx.se/bug/view.cgi?id=1779054) pointed
  out that libcurl didn't deal with very long (>16K) FTP server response lines
  properly. Starting now, libcurl will chop them off (thus the client app will
  not get the full line) but survive and deal with them fine otherwise. Test
  case 1003 was added to verify this.

Daniel S (20 August 2007)
- Based on a patch by Christian Vogt, the FTP code now sets the upcoming
  download transfer size much earlier to be possible to get read with
  CURLINFO_CONTENT_LENGTH_DOWNLOAD as soon as possible. This is very much in a
  similar spirit to the HTTP size change from August 11 2007.

Daniel S (18 August 2007)
- Robson Braga Araujo filed bug report #1776232
  (https://curl.haxx.se/bug/view.cgi?id=1776232) about libcurl calling
  Curl_client_write(), passing on a const string that the caller may not
  modify and yet it does (on some platforms).

- Robson Braga Araujo filed bug report #1776235
  (https://curl.haxx.se/bug/view.cgi?id=1776235) about ftp requests with NOBODY
  on a directory would do a "SIZE (null)" request. This is now fixed and test
  case 1000 was added to verify.

Daniel S (17 August 2007)
- Song Ma provided a patch that cures a problem libcurl has when doing resume
  HTTP PUT using Digest authentication. Test case 5320 and 5322 were also
  added to verify the functionality.

Daniel S (14 August 2007)
- Andrew Wansink provided an NTLM bugfix: in the case the server sets the flag
  NTLMFLAG_NEGOTIATE_UNICODE, we need to filter it off because libcurl doesn't
  UNICODE encode the strings it packs into the NTLM authenticate packet.

Daniel S (11 August 2007)
- Allen Pulsifer provided a patch that makes libcurl set the expected download
  size earlier when doing HTTP downloads, so that applications and the
  progress meter etc know get the info earlier in the flow than before.

- Patrick Monnerat modified the LDAP code and approach in curl. Starting now,
  the configure script checks for openldap and friends and we link with those
  libs just like we link all other third party libraries, and we no longer
  dlopen() those libraries. Our private header file lib/ldap.h was renamed to
  lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix)
  just before this commit, just in case.

Dan F (8 August 2007)
- Song Ma noted a zlib memory leak in the illegal compressed header
  countermeasures code path.

Daniel S (4 August 2007)
- Patrick Monnerat fixed curl_easy_escape() and curlx_strtoll() to work on
  non-ASCII systems.

Daniel S (3 August 2007)
- I cut out support for libssh2 versions older than 0.16 to make our code a
  lot simpler, and to avoid getting trouble with the LIBSSH2_APINO define
  that 1) didn't work properly since it was >32 bits and 2) is removed in
  libssh2 0.16...

Daniel S (2 August 2007)
- Scott Cantor filed bug report #1766320
  (https://curl.haxx.se/bug/view.cgi?id=1766320) pointing out that the libcurl
  code accessed two curl_easy_setopt() options (CURLOPT_DNS_CACHE_TIMEOUT and
  CURLOPT_DNS_USE_GLOBAL_CACHE) as ints even though they're documented to be
  passed in as longs, and that makes a difference on 64 bit architectures.

- Dmitriy Sergeyev reported a regression: resumed file:// transfers broke
  after 7.16.2. This is much due to the different treatment file:// gets
  internally, but now I added test 231 to make it less likely to happen again
  without us noticing!

Daniel S (1 August 2007)
- Patrick Monnerat and I modified libcurl so that now it *copies* all strings
  passed to it with curl_easy_setopt()! Previously it has always just refered
  to the data, forcing the user to keep the data around until libcurl is done
  with it. That is now history and libcurl will instead clone the given
  strings and keep private copies. This is also part of Patrick Monnerat's
  OS/400 port.

  Due to this being a somewhat interesting change API wise, I've decided to
  bump the version of the upcoming release to 7.17.0. Older applications will
  of course not notice this change nor do they have to care, but new
  applications can be written to take advantage of this.

- Greg Morse reported a problem with POSTing using ANYAUTH to a server
  requiring NTLM, and he provided test code and a test server and we worked
  out a bug fix. We failed to count sent body data at times, which then caused
  internal confusions when libcurl tried to send the rest of the data in order
  to maintain the same connection alive.

Daniel S (31 July 2007)
- Peter O'Gorman pointed out (and fixed) that the non-blocking check in
  configure made libcurl use blocking sockets on AIX 4 and 5, while that
  wasn't the intention.

Daniel S (29 July 2007)
- Jayesh A Shah filed bug report #1759542
  (https://curl.haxx.se/bug/view.cgi?id=1759542) identifying a rather serious
  problem with FTPS: libcurl closed the data connection socket and then later
  in the flow it would call the SSL layer to do SSL shutdown which then would
  use a socket that had already been closed - so if the application had opened
  a new one in the mean time, libcurl could send gibberish that way! I worked
  with Greg Zavertnik to properly diagnose and fix this. The fix affects code
  for all SSL libraries we support, but it has only been truly verified to
  work fine for the OpenSSL version. The others have only been code reviewed.

Daniel S (23 July 2007)
- Implemented the parts of Patrick Monnerat's OS/400 patch that introduces
  support for the OS/400 Secure Sockets Layer library.

Dan F (23 July 2007)
- Implemented only the parts of Patrick Monnerat's OS/400 patch that renamed
  some few internal identifiers to avoid conflicts, which could be useful on
  other platforms.

Daniel S (22 July 2007)
- HTTP Digest bug fix by Chris Flerackers:

  Scenario

  - Perfoming a POST request with body
  - With authentication (only Digest)
  - Re-using a connection

  libcurl would send a HTTP POST with an Authorization header but without
  body. Our server would return 400 Bad Request in that case (because
  authentication passed, but the body was empty).

  Cause

  1) http_digest.c -> Curl_output_digest
  - Updates allocptr.userpwd/allocptr.proxyuserpwd *only* if d->nonce is
  filled in (and no errors)
  - authp->done = TRUE if d->nonce is filled in
  2) http.c -> Curl_http
  - *Always* uses allocptr.userpwd/allocptr.proxyuserpwd if not NULL
  3) http.c -> Curl_http, Curl_http_output_auth

  So what happens is that Curl_output_digest cannot yet update the
  Authorization header (allocptr.userpwd) which results in authhost->done=0 ->
  authhost->multi=1 -> conn->bits.authneg = TRUE.  The body is not
  added. *However*, allocptr.userpwd is still used when building the request

- Added test case 354 that makes a simple FTP retrieval without password, which
  verifies the bug fix in #1757328.

Daniel S (21 July 2007)
- To allow more flexibility in FTP test cases, I've removed the enforced states
  from the test server code as they served no real purpose. The test server
  is here to serve for the test cases, not to attempt to function as a real
  server! While at it, I modified test case 141 to better test and verify
  curl -I on a single FTP file.

Daniel S (20 July 2007)
- James Housley fixed the SFTP PWD command to work.

- Ralf S. Engelschall filed bug report #1757328
  (https://curl.haxx.se/bug/view.cgi?id=1757328) and submitted a patch. It
  turns out we broke login to FTP servers that don't require (nor understand)
  PASS after the USER command. The breakage was done as part of the krb5
  commit so a krb-using person needs to verify that the current version now
  works or if we need to fix it (in a different way of course).

Dan F (17 July 2007)
- Fixed test cases 613 and 614 by improving the log postprocessor to handle
  a new directory listing format that newer libssh2's can provide.  This
  is probably NOT sufficient to handle all directory listing formats that
  server's can provide, and should be revisited.

Daniel S (17 July 2007)
- Daniel Johnson fixed a bug in how libssh2_session_last_error() was used, in
  two places.

- Jofell Gallardo posted a libcurl log using FTP that exposed a bug which made
  a control connection that was deemed "dead" to yet be re-used in a following
  request.

Daniel S (13 July 2007)
- Colin Hogben filed bug report #1750274
  (https://curl.haxx.se/bug/view.cgi?id=1750274) and submitted a patch for the
  case where libcurl did a connect attempt to a non-listening port and didn't
  provide a human readable error string back.

- Daniel Cater fixes:
  1 - made 'make vc8' work on windows.
  2 - made libcurl itself built with CURL_NO_OLDIES defined (which doesn't
      define the symbols for backwards source compatibility)
  3 - updated libcurl-errors.3
  4 - added CURL_DISABLE_TFTP to docs/INSTALL

Daniel S (12 July 2007)
- Made the krb5 code build with Heimdal's GSSAPI lib.

Dan F (12 July 2007)
- Compile most of the example apps in docs/examples when doing a 'make check'.
  Fixed some compile warnings and errors in those examples.

- Removed the example program ftp3rdparty.c since libcurl doesn't support
  3rd party FTP transfers any longer.

Daniel S (12 July 2007)
- Shmulik Regev found an (albeit rare) case where the proxy CONNECT operation
  could in fact get stuck in an endless loop.

- Made CURLOPT_SSL_VERIFYHOST set to 1 acts as described in the documentation:
  fail to connect if there is no Common Name field found in the remote cert.
  We should deprecate the support for this set to 1 anyway soon, since the
  feature is pointless and most likely never really used by anyone.

Daniel S (11 July 2007)
- Shmulik Regev fixed a bug with transfer-encoding skipping during the 407
  error pages for proxy authentication.

- Giancarlo Formicuccia reported and fixed a problem with a closed connection
  to a proxy during CONNECT auth negotiation.

Dan F (10 July 2007)
- Fixed a curl memory leak reported by Song Ma with a modified version
  of the patch he suggested.  Added his test case as test289 to verify.

- Force the time zone to GMT in the cookie tests in case the user is
  using one of the so-called 'right' time zones that take into account
  leap seconds, which causes the tests to fail (as reported by
  Daniel Black in bug report #1745964).

Version 7.16.4 (10 July 2007)

Daniel S (10 July 2007)
- Kees Cook notified us about a security flaw
  (https://curl.haxx.se/docs/adv_20070710.html) in which libcurl failed to
  properly reject some outdated or not yet valid server certificates when
  built with GnuTLS. Kees also provided the patch.

James H (5 July 2007)
- Gavrie Philipson provided a patch that will use a more specific error
  message for an scp:// upload failure.  If libssh2 has his matching
  patch, then the error message return by the server will be used instead
  of a more generic error.

Daniel S (1 July 2007)
- Thomas J. Moore provided a patch that introduces Kerberos5 support in
  libcurl. This also makes the options change name to --krb (from --krb4) and
  CURLOPT_KRBLEVEL (from CURLOPT_KRB4LEVEL) but the old names are still

- Song Ma helped me verify and extend a fix for doing FTP over a SOCKS4/5
  proxy.

Daniel S (27 June 2007)
- James Housley: Add two new options for the SFTP/SCP/FILE protocols:
  CURLOPT_NEW_FILE_PERMS and CURLOPT_NEW_DIRECTORY_PERMS. These control the
  premissions for files and directories created on the remote
  server. CURLOPT_NEW_FILE_PERMS defaults to 0644 and
  CURLOPT_NEW_DIRECTORY_PERMS defaults to 0755

- I corrected the 10-at-a-time.c example and applied a patch for it by James
  Bursa.

Daniel S (26 June 2007)
- Robert Iakobashvili re-arranged the internal hash code to work with a custom
  hash function for different hashes, and also expanded the default size for
  the socket hash table used in multi handles to greatly enhance speed when
  very many connections are added and the socket API is used.

- James Housley made the CURLOPT_FTPLISTONLY mode work for SFTP directory
  listings as well

Daniel S (25 June 2007)
- Adjusted how libcurl treats HTTP 1.1 responses without content-lenth or
  chunked encoding (that also lacks "Connection: close"). It now simply
  assumes that the connection WILL be closed to signal the end, as that is how
  RFC2616 section 4.4 point #5 says we should behave.

Version 7.16.3 (25 June 2007)

Daniel S (23 June 2007)
- As reported by "Tro" in https://curl.haxx.se/mail/lib-2007-06/0161.html and
  https://curl.haxx.se/mail/lib-2007-06/0238.html, libcurl didn't properly do
  no-body requests on FTP files on re-used connections properly, or at least
  it didn't provide the info back in the header callback properly in the
  subsequent requests.

Daniel S (21 June 2007)
- Gerrit Bruchhäuser pointed out a warning that the Intel(R) Thread Checker
  tool reports and it was indeed a legitimate one and it is one fixed. It was
  a use of a share without doing the proper locking first.

Daniel S (20 June 2007)
- Adam Piggott filed bug report #1740263
  (https://curl.haxx.se/bug/view.cgi?id=1740263). Adam discovered that when
  getting a large amount of URLs with curl, they were fetched slower and
  slower... which turned out to be because the --libcurl data collecting which
  wrongly always was enabled, but no longer is...

Daniel S (18 June 2007)
- Robson Braga Araujo filed bug report #1739100
  (https://curl.haxx.se/bug/view.cgi?id=1739100) that mentioned that libcurl
  could not actually list the contents of the root directory of a given FTP
  server if the login directory isn't root. I fixed the problem and added
  three test cases (one is disabled for now since I identified KNOWN_BUGS #44,
  we cannot use --ftp-method nocwd and list ftp directories).

Daniel S (14 June 2007)
- Shmulik Regev:

  I've encountered (and hopefully fixed) a problem involving proxy CONNECT
  requests and easy handles state management. The problem isn't simple to
  reproduce since it depends on socket state. It only manifests itself when
  working with non-blocking sockets.

  Here is the scenario:

  1. in multi_runsingle the easy handle is in the CURLM_STATE_WAITCONNECT and
  calls Curl_protocol_connect

  2. in Curl_proxyCONNECT, line 1247, if the socket isn't ready the function
  returns and conn->bits.tunnel_connecting is TRUE

  3. when the call to Curl_protocol_connect returns the protocol_connect flag
  is false and the easy state is changed to CURLM_STATE_PROTOCONNECT which
  isn't correct if a proxy is used.  Rather CURLM_STATE_WAITPROXYCONNECT
  should be used.

  I discovered this while performing an HTTPS request through a proxy (squid)
  on my local network. The problem caused openssl to fail as it read the proxy
  response to the CONNECT call ('HTTP/1.0 Established') rather than the SSL
  handshake (the exact openssl error was 'wrong ssl version' but this isn't
  very important)

- Dave Vasilevsky filed bug report #1736875
  (https://curl.haxx.se/bug/view.cgi?id=1736875) almost simultanouesly as Dan
  Fandrich mentioned a related build problem on the libcurl mailing list:
  https://curl.haxx.se/mail/lib-2007-06/0131.html. Both problems had the same
  reason: the definitions of the POLL* defines and the pollfd struct in the
  libcurl code was depending on HAVE_POLL instead of HAVE_SYS_POLL_H.

Daniel S (13 June 2007)
- Tom Regner provided a patch and worked together with James Housley, so now
  CURLOPT_FTP_CREATE_MISSING_DIRS works for SFTP connections as well as FTP
  ones.

- Rich Rauenzahn filed bug report #1733119
  (https://curl.haxx.se/bug/view.cgi?id=1733119) and we collaborated on the
  fix.  The problem is that for 64bit HPUX builds, several socket-related
  functions would still assume int (32 bit) arguments and not socklen_t (64
  bit) ones.

Daniel S (12 June 2007)
- James Housley brought his revamped SSH code that is state-machine driven to
  really take advantage of the now totally non-blocking libssh2 (in CVS).

Dan F (8 June 2007)
- Incorporated Daniel Black's test706 and test707 SOCKS test cases.

- Fixed a few problems when starting the SOCKS server.

- Reverted some recent changes to runtests.pl that weren't compatible with
  perl 5.0.

- Fixed the test harness so that it actually kills the ssh being used as
  the SOCKS server.

Daniel S (6 June 2007)
- -s/--silent can now be used to toggle off the silence again if used a second
  time.

Daniel S (5 June 2007)
- Added Daniel Black's work that adds the first few SOCKS test cases. I also
  fixed two minor SOCKS problems to make the test cases run fine.

Daniel S (31 May 2007)
- Feng Tu made (lib)curl support "upload" resuming work for file:// URLs.

Daniel S (30 May 2007)
- I modified the 10-at-a-time.c example to transfer 500 downloads in parallel
  with a c-ares enabled build only to find that it crashed miserably, and this
  was due to some select()isms left in the code. This was due to API
  restrictions in c-ares 1.3.x, but with the upcoming c-ares 1.4.0 this is no
  longer the case so now libcurl runs much better with c-ares and the multi
  interface with > 1024 file descriptors in use.

  Extra note: starting now we require c-ares 1.4.0 for asynchronous name
  resolves.

- Added CURLMOPT_MAXCONNECTS which is a curl_multi_setopt() option for setting
  the maximum size of the connection cache maximum size of the multi handle.

Daniel S (27 May 2007)
- When working with a problem Stefan Becker had, I found an off-by-one buffer
  overwrite in Curl_select(). While fixing it, I also improved its performance
  somewhat by changing calloc to malloc and breaking out of a loop earlier
  (when possible).

Daniel S (25 May 2007)
- Rob Crittenden fixed bug #1705802
  (https://curl.haxx.se/bug/view.cgi?id=1705802), which was filed by Daniel
  Black identifying several FTP-SSL test cases fail when we build libcurl with
  NSS for TLS/SSL. Listed as #42 in KNOWN_BUGS.

Daniel S (24 May 2007)
- Song Ma filed bug report #1724016
  (https://curl.haxx.se/bug/view.cgi?id=1724016) noticing that downloading
  glob-ranges for TFTP was broken in CVS. Fixed now.

- 'mytx' in bug report #1723194 (https://curl.haxx.se/bug/view.cgi?id=1723194)
  pointed out that the warnf() function in the curl tool didn't properly deal
  with the cases when excessively long words were used in the string to chop
  up.

Daniel S (22 May 2007)
- Andre Guibert de Bruet fixed a memory leak in the function that verifies the
  peer's name in the SSL certificate when built for OpenSSL. The leak happens
  for libcurls with CURL_DOES_CONVERSIONS enabled that fail to convert the CN
  name from UTF8. He also fixed a leak when PKCS #12 parsing failed.

Daniel S (18 May 2007)
- Feng Tu reported that curl -w did wrong on TFTP transfers in bug report
  #1715394 (https://curl.haxx.se/bug/view.cgi?id=1715394), and the
  transfer-related info "variables" were indeed overwritten with zeroes
  wrongly and have now been adjusted. The upload size still isn't accurate.

Daniel S (17 May 2007)
- Feng Tu pointed out a division by zero error in the TFTP connect timeout
  code for timeouts less than five seconds, and also provided a fix for it.
  Bug report #1715392 (https://curl.haxx.se/bug/view.cgi?id=1715392)

Dan F (16 May 2007)
- Added support for compiling under Minix 3.1.3 using ACK.

Dan F (14 May 2007)
- Added SFTP directory listing test case 613.

- Added support for quote commands before a transfer using SFTP and test
  case 614.

- Changed the post-quote commands to occur after the transferred file is
  closed.

- Allow SFTP quote commands chmod, chown, chgrp to set a value of 0.

Dan F (9 May 2007)
- Kristian Gunstone fixed a problem where overwriting an uploaded file with
  sftp didn't truncate it first, which would corrupt the file if the new
  file was shorter than the old.

Dan F (8 May 2007)
- Added FTPS test cases 406 and 407

Daniel S (8 May 2007)
- CURLE_FTP_COULDNT_STOR_FILE is now known as CURLE_UPLOAD_FAILED. This is
  because I just made SCP uploads return this value if the file size of
  the upload file isn't given with CURLOPT_INFILESIZE*. Docs updated to
  reflect this news, and a define for the old name was added to the public
  header file.

Daniel S (7 May 2007)
- James Bursa fixed a bug in the multi handle code that made the connection
  cache grow a bit too much, beyond the normal 4 * easy_handles.

Daniel S (2 May 2007)
- Anders Gustafsson remarked that requiring CURLOPT_HTTP_VERSION set to 1.0
  when CURLOPT_HTTP200ALIASES is used to avoid the problem mentioned below is
  not very nice if the client wants to be able to use _either_ a HTTP 1.1
  server or one within the aliases list... so starting now, libcurl will
  simply consider 200-alias matches the to be HTTP 1.0 compliant.

- Tobias Rundström reported a problem they experienced with xmms2 and recent
  libcurls, which turned out to be the 25-nov-2006 change which treats HTTP
  responses without Content-Length or chunked encoding as without bodies. We
  now added the conditional that the above mentioned response is only without
  body if the response is HTTP 1.1.

- Jeff Pohlmeyer improved the hiperfifo.c example to use the
  CURLMOPT_TIMERFUNCTION callback option.

- Set the timeout for easy handles to expire really soon after addition or
  when CURLM_CALL_MULTI_PERFORM is returned from curl_multi_socket*/perform,
  to make applications using only curl_multi_socket() to properly function
  when adding easy handles "on the fly". Bug report and test app provided by
  Michael Wallner.

Dan F (30 April 2007)
- Improved the test harness to allow running test servers on other than
  the default port numbers, allowing more than one test suite to run
  simultaneously on the same host.

Daniel S (28 April 2007)
- Peter O'Gorman fixed libcurl to not init GnuTLS as early as we did before,
  since it then inits libgcrypt and libgcrypt is being evil and EXITS the
  application if it fails to get a fine random seed. That's really not a nice
  thing to do by a library.

- Frank Hempel fixed a curl_easy_duphandle() crash on a handle that had
  been removed from a multi handle, and then fixed another flaw that prevented
  curl_easy_duphandle() to work even after the first fix - the handle was
  still marked as using the multi interface.

Daniel S (26 April 2007)
- Peter O'Gorman found a problem with SCP downloads when the downloaded file
  was 16385 bytes (16K+1) and it turned out we didn't properly always "suck
  out" all data from libssh2. The effect being that libcurl would hang on the
  socket waiting for data when libssh2 had in fact already read it all...

Dan F (25 April 2007)
- Added support in runtests.pl for "!n" test numbers to disable individual
  tests.  Changed -t to only keep log files around when -k is specified,
  to have the same behaviour as without -t.

Daniel S (25 April 2007)
- Sonia Subramanian brought our attention to a problem that happens if you set
  the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection
  in the connection cache is closed to make room for the new one when you call
  curl_easy_perform(). It would then wrongly free range-related data in the
  connection close funtion.

Yang Tse (25 April 2007)
- Steve Little fixed compilation on VMS 64-bit mode

Daniel S (24 April 2007)
- Robert Iakobashvili made the 'master_buffer' get allocated first once it is
  can/will be used as it then makes the common cases save 16KB of data for each
  easy handle that isn't used for pipelining.

Dan F (23 April 2007)
- Added <postcheck> support to the test harness.

- Added tests 610-612 to test more SFTP post-quote commands.

Daniel S (22 April 2007)
- Song Ma's warning if -r/--range is given with a "bad" range, also noted in
  the man page now.

- Daniel Black filed bug #1705177
  (https://curl.haxx.se/bug/view.cgi?id=1705177) where --without-ssl
  --with-gnutl outputs a warning about SSL not being enabled even though GnuTLS
  was found and used.

Daniel S (21 April 2007)
- Daniel Black filed bug #1704675
  (https://curl.haxx.se/bug/view.cgi?id=1704675) identifying a double-free
  problem in the SSL-dealing layer, telling GnuTLS to free NULL credentials on
  closedown after a failure and a bad #ifdef for NSS when closing down SSL.

Yang Tse (20 April 2007)
- Save one call to curlx_tvnow(), which calls gettimeofday(), in each of
  Curl_socket_ready(), Curl_poll() and Curl_select() when these are called
  with a zero timeout or a timeout value indicating a blocking call should
  be performed.

Daniel S (18 April 2007)
- James Housley made SFTP uploads use libssh2's non-blocking API

- Prevent the internal progress meter from updating more frequently than once
  per second.

Dan F (17 April 2007)
- Added test cases 296, 297 and 298 to test --ftp-method handling

Daniel S (16 April 2007)
- Robert Iakobashvil added curl_multi_socket_action() to libcurl, which is a
  function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the
  socket that it passes in. This gives a significant performance boost as it
  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().

  I added a define in the public curl/multi.h header file that will make your
  existing application automatically use curl_multi_socket_action() instead of
  curl_multi_socket() when you recompile. But of course you'll get better
  performance if you adjust your code manually and actually pass in the
  correct action bitmask to this function.

Daniel S (14 April 2007)
- Jay Austin added "DH PARAMETERS" to the stunnel.pem certificate for the test
  suite to make stunnel run better in some (most?) environments.

Dan F (13 April 2007)
- Added test cases 294 and 295 to test --ftp-account handling

- Improved handling of out of memory in ftp.

Yang Tse (13 April 2007)
- Fix test case 534 which started to fail 2007-04-13 due to the existance
  of a new host on the net with the same silly domain the test was using
  for a host which was supposed not to exist.

Daniel S (12 April 2007)
- Song Ma found a memory leak in the if2ip code if you pass in an interface
  name longer than the name field of the ifreq struct (typically 6 bytes), as
  then it wouldn't close the used dummy socket. Bug #1698974
  (https://curl.haxx.se/bug/view.cgi?id=1698974)

Version 7.16.2 (11 April 2007)

Yang Tse (10 April 2007)
- Ravi Pratap provided some fixes for HTTP pipelining

- configure script will ignore --enable-sspi option for non-native Windows.

Daniel S (9 April 2007)
- Nick Zitzmann did ssh.c cleanups

Daniel S (3 April 2007)
- Rob Jones fixed better #ifdef'ing for a bunch of #include lines.

Daniel S (2 April 2007)
- Nick Zitzmann made the CURLOPT_POSTQUOTE option work for SFTP as well. The

Daniel S (1 April 2007)
- Robert Iakobashvili made curl_multi_remove_handle() a lot faster when many
  easy handles are added to a multi handle, by avoiding the looping over all
  the handles to find which one to remove.

- Matt Kraai provided a patch that makes curl build on QNX 6 fine again.

Daniel S (31 March 2007)
- Fixed several minor issues detected by the coverity.com scanner.

- "Pixel" fixed a problem that appeared when you used -f with user+password
  embedded in the URL.

Dan F (29 March 2007)
- Don't tear down the ftp connection if the maximum filesize was exceeded
  and added tests 290 and 291 to check.

- Added ftps upload and SSL required tests 401 and 402.

- Send an EOF message before closing an SCP channel, as recommended by
  RFC4254. Enable libssh2 tracing when ssh debugging is turned on.

Yang Tse (27 March 2007)
- Internal function Curl_select() renamed to Curl_socket_ready()

  New Internal wrapper function Curl_select() around select (2), it
  uses poll() when a fine poll() is available, so now libcurl can be
  built without select() support at all if a fine poll() is available.

Daniel S (25 March 2007)
- Daniel Johnson fixed multi code to traverse the easy handle list properly.
  A left-over bug from the February 21 fix.

Dan F (23 March 2007)
- Added --pubkey option to curl and made --key also work for SCP/SFTP,
  plus made --pass work on an SSH private key as well.

- Changed the test harness to attempt to gracefully shut down servers
  before resorting to the kill -9 hammer.

- Added test harness infrastructure to support scp/sftp tests, using
  OpenSSH as the server.

- Fixed a memory leak when specifying a proxy with a file: URL.

Yang Tse (20 March 2007)
- Fixed: When a signal was caught awaiting for an event using Curl_select()
  or Curl_poll() with a non-zero timeout both functions would restart the
  specified timeout. This could even lead to the extreme case that if a
  signal arrived with a frecuency lower to the specified timeout neither
  function would ever exit.

  Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
  Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
  defined both functions will return as soon as a signal is caught. Use it
  at your own risk, all calls to these functions in the library should be
  revisited and checked before fully supporting this feature.

Yang Tse (19 March 2007)
- Bryan Henderson fixed the progress function so that it can get called more
  frequently allowing same calling frecuency for the client progress callback.

Dan F (15 March 2007)
- Various memory leaks plugged and NULL pointer fixes made in the ssh code.

Daniel (15 March 2007)
- Nick made the curl tool accept globbing ranges that only is one number, i.e
  you can now use [1-1] without curl complaining.

Daniel (10 March 2007)
- Eygene Ryabinkin:

  The problem is the following: when we're calling Curl_done and it decides to
  keep the connection opened ('left intact'), then the caller is not notified
  that the connection was done via the NULLifying of the pointer, so some easy
  handle is keeping the pointer to this connection.

  Later ConnectionExists can select such connection for reuse even if we're
  not pipelining: pipeLen is zero, so the (pipeLen > 0 && !canPipeline) is
  false and we can reuse this connection for another easy handle. But thus the
  connection will be shared between two easy handles if the handle that wants
  to take the ownership is not the same as was not notified of the connection
  was done in Curl_done. And when some of these easy handles will get their
  connection really freed the another one will still keep the pointer.

  My fix was rather trivial: I just added the NULLification to the 'else'
  branch in the Curl_done. My tests with Git and ElectricFence showed no
  problems both for HTTP pulling and cloning. Repository size is about 250 Mb,
  so it was a considerable amount of Curl's work.

Dan F (9 March 2007)
- Updated the test harness to add a new "crypto" feature check and updated the
  appropriate test case to use it.  For now, this is treated the same as the
  "SSL" feature because curl doesn't list it separately.

Daniel (9 March 2007)
- Robert Iakobashvili fixed CURLOPT_INTERFACE for IPv6.

- Robert A. Monat improved the maketgz and VC6/8 generating to set the correct
  machine type too.

- Justin Fletcher fixed a file descriptor leak in the curl tool when trying to
  upload a file it couldn't open. Bug #1676581
  (https://curl.haxx.se/bug/view.cgi?id=1676581)

Dan F (9 March 2007)
- Updated the test harness to check for protocol support before running each
  test, fixing KNOWN_BUGS #11.

Dan F (7 March 2007)
- Reintroduced (after a 3 year hiatus) an FTPS test case (400) into the test
  harness.  It is very limited as it supports only ftps:// URLs with
  --ftp-ssl-control specified, which implicitly encrypts the control
  channel but not the data channels.  That allows stunnel to be used with
  an unmodified ftp server in exactly the same way that the test https
  server is set up.

Dan F (7 March 2007)
- Honour --ftp-ssl-control on ftps:// URLs to allow encrypted control and
  unencrypted data connections.

Dan F (6 March 2007)
- Fixed a couple of improper pointer uses detected by valgrind in test
  cases 181 & 216.

Daniel (2 March 2007)
- Robert A. Monat and Shmulik Regev helped out to fix the new */Makefile.vc8
  makefiles that are included in the source release archives, generated from
  the Makefile.vc6 files by the maketgz script. I also modified the root
  Makefile to have a VC variable that defaults to vc6 but can be overridden to
  allow it to be used for vc8 as well. Like this:

    nmake VC=vc8 vc

Daniel (27 February 2007)
- Hang Kin Lau found and fixed: When I use libcurl to connect to an https
  server through a proxy and have the remote https server port set using the
  CURLOPT_PORT option, protocol gets reset to http from https after the first
  request.

  User defined URL was modified internally by libcurl and subsequent reuse of
  the easy handle may lead to connection using a different protocol (if not
  originally http).

  I found that libcurl hardcoded the protocol to "http" when it tries to
  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
  follows and it's working fine so far

Daniel (25 February 2007)
- Adam D. Moss made the HTTP CONNECT procedure less blocking when used from
  the multi interface. Note that it still does a part of the connection in a
  blocking manner.

Daniel (23 February 2007)
- Added warning outputs if the command line uses more than one of the options
  -v, --trace and --trace-ascii, since it could really confuse the user.
  Clarified this fact in the man page.

Daniel (21 February 2007)
- Ravi Pratap provided work on libcurl making pipelining more robust and
  fixing some bugs:
  o Don't mix GET and POST requests in a pipeline
  o Fix the order in which requests are dispatched from the pipeline
  o Fixed several curl bugs with pipelining when the server is returning
    chunked encoding:
    * Added states to chunked parsing for final CRLF
    * Rewind buffer after parsing chunk with data remaining
    * Moved chunked header initializing to a spot just before receiving
      headers

Daniel (20 February 2007)
- Linus Nielsen Feltzing changed the CURLOPT_FTP_SSL_CCC option to handle
  active and passive CCC shutdown and added the --ftp-ssl-ccc-mode command
  line option.

Daniel (19 February 2007)
- Ian Turner fixed the libcurl.m4 macro's support for --with-libcurl.

- Shmulik Regev found a memory leak in re-used HTTPS connections, at least
  when the multi interface was used.

- Robson Braga Araujo made passive FTP transfers work with SOCKS (both 4 and
  5).

Daniel (18 February 2007)
- Jeff Pohlmeyer identified two problems: first a rather obscure problem with
  the multi interface and connection re-use that could make a
  curl_multi_remove_handle() ruin a pointer in another handle.

  The second problem was less of an actual problem but more of minor quirk:
  the re-using of connections wasn't properly checking if the connection was
  marked for closure.

Daniel (16 February 2007)
- Duncan Mac-Vicar Prett and Michal Marek reported problems with resetting
  CURLOPT_RANGE back to no range on an easy handle when using FTP.

Dan F (14 February 2007)
- Fixed curl-config --libs so it doesn't list unnecessary libraries (and
  therefore introduce unnecessary dependencies) when it's not needed.
  Also, don't bother adding a library path of /usr/lib

Daniel (13 February 2007)
- The default password for anonymous FTP connections is now changed to be
  "ftp@example.com".

- Robert A. Monat made libcurl build fine with VC2005 - it doesn't have
  gmtime_r() like the older VC versions. He also made use of some machine-
  specific defines to differentiate the "OS" define.

Daniel (12 February 2007)
- Rob Crittenden added support for NSS (Network Security Service) for the
  SSL/TLS layer. https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS

  This is the fourth supported library for TLS/SSL that libcurl supports!

- Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent
  to the debug callback.

- Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and
  CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's
  internal decoding of content or transfer encoded content. This may be
  preferable in cases where you use libcurl for proxy purposes or similar. The
  command line tool got a --raw option to disable both at once.

- release tarballs made with maketgz will from now on have a LIBCURL_TIMESTAMP
  define set to hold the exact date and time of when the tarball was built, as
  a human readable string using the UTC time zone.

- Jeff Pohlmeyer fixed a flaw in curl_multi_add_handle() when adding a handle
  that has an easy handle present in the "closure" list pending closure.

Daniel (6 February 2007)
- Regular file downloads wiht SFTP and SCP are now done using the non-blocking
  API of libssh2, if the libssh2 headers seem to support them. This will make
  SCP and SFTP much more responsive and better libcurl citizens when used with
  the multi interface etc.

Daniel (5 February 2007)
- Michael Wallner added support for CURLOPT_TIMEOUT_MS and
  CURLOPT_CONNECTTIMEOUT_MS that, as their names suggest, do the timeouts with
  millisecond resolution. The only restriction to that is the alarm()
  (sometimes) used to abort name resolves as that uses full seconds. I fixed
  the FTP response timeout part of the patch.

  Internally we now count and keep the timeouts in milliseconds but it also
  means we multiply set timeouts with 1000. The effect of this is that no
  timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
  equals 24.86 days.  We probably couldn't before either since the code did
  *1000 on the timeout values on several places already.

Daniel (3 February 2007)
- Yang Tse fixed the cookie expiry date in several test cases that started to
  fail since they used "1 feb 2007"...

- Manfred Schwarb reported that socks5 support was broken and help us pinpoint
  the problem. The code now tries harder to use httproxy and proxy where
  apppropriate, as not all proxies are HTTP...

Version 7.16.1 (29 January 2007)

Daniel (29 January 2007)
- Michael Wallner reported that when doing a CONNECT with a custom User-Agent
  header, you got _two_ User-Agent headers in the CONNECT request...! Added
  test case 287 to verify the fix.

Daniel (28 January 2007)
- curl_easy_reset() now resets the CA bundle path correctly.

- David McCreedy fixed the Curl command line tool for HTTP on non-ASCII
  platforms.

Daniel (25 January 2007)
- Added the --libcurl [file] option to curl. Append this option to any
  ordinary curl command line, and you will get a libcurl-using source code
  written to the file that does the equivalent operation of what your command
  line operation does!

Dan F (24 January 2007)
- Fixed a dangling pointer problem that prevented the http_proxy environment
  variable from being properly used in many cases (and caused test case 63
  to fail).

Daniel (23 January 2007)
- David McCreedy did NTLM changes mainly for non-ASCII platforms:

  #1
  There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT
  defined.  I noticed this while testing various configurations.  Line 867 of
  the current http_ntlm.c is a closing bracket for an if/else pair that only
  gets compiled in if USE_NTLM2SESSION is defined.  But this closing bracket
  wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was
  defined.  Lines 198 and 140 of my patch wraps that closing bracket in an
  #ifdef USE_NTLM2SESSION.

  #2
  I noticed several picky compiler warnings when DEBUG_ME is defined.  I've
  fixed them with casting.  By the way, DEBUG_ME was a huge help in
  understanding this code.

  #3
  Hopefully the last non-ASCII conversion patch for libcurl in a while.  I
  changed the "NTLMSSP" literal to hex since this signature must always be in
  ASCII.

  Conversion code was strategically added where necessary.  And the
  Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c
  creates are NOT translated on non-ASCII platforms.

Dan F (22 January 2007)
- Converted (most of) the test data files into genuine XML.  A handful still
  are not, due mainly to the lack of support for XML character entities
  (e.g. & => &amp; ).  This will make it easier to validate test files using
  tools like xmllint, as well as to edit and view them using XML tools.

Daniel (16 January 2007)
- Armel Asselin improved libcurl to behave a lot better when an easy handle
  doing an FTP transfer is removed from a multi handle before completion. The
  fix also fixed the "alive counter" to be correct on "premature removal" for
  all protocols.

Dan F (16 January 2007)
- Fixed a small memory leak in tftp uploads discovered by curl's memory leak
  detector.  Also changed tftp downloads to URL-unescape the downloaded
  file name.

Daniel (14 January 2007)
- David McCreedy provided libcurl changes for doing HTTP communication on
  non-ASCII platforms. It does add some complexity, most notably with more
  #ifdefs, but I want to see this supported added and I can't see how we can
  add it without the extra stuff added.

- Setting CURLOPT_COOKIELIST to "ALL" when no cookies at all was present,
  libcurl would crash when trying to read a NULL pointer.

Daniel (12 January 2007)
- Toby Peterson found a nasty bug that prevented (lib)curl from properly
  downloading (most) things that were larger than 4GB on 32 bit systems.  Matt
  Witherspoon helped as narrow down the problem.

Daniel (5 January 2007)
- Linus Nielsen Feltzing introduced the --ftp-ssl-ccc command line option to
  curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it
  will make libcurl shutdown SSL/TLS after the authentication is done on a
  FTP-SSL operation.

Daniel (4 January 2007)
- David McCreedy made changes to allow base64 encoding/decoding to work on
  non-ASCII platforms.

Daniel (3 January 2007)
- Matt Witherspoon fixed the flaw which made libcurl 7.16.0 always store
  downloaded data in two buffers, just to be able to deal with a special HTTP
  pipelining case. That is now only activated for pipelined transfers. In
  Matt's case, it showed as a considerable performance difference,

Daniel (2 January 2007)
- Victor Snezhko helped us fix bug report #1603712
  (https://curl.haxx.se/bug/view.cgi?id=1603712) (known bug #36) --limit-rate
  (CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE) are broken
  on Windows (since 7.16.0, but that's when they were introduced as previous
  to that the limiting logic was made in the application only and not in the
  library). It was actually also broken on select()-based systems (as apposed
  to poll()) but we haven't had any such reports. We now use select(), Sleep()
  or delay() properly to sleep a while without waiting for anything input or
  output when the rate limiting is activated with the easy interface.

- Modified libcurl.pc.in to use Libs.private for the libs libcurl itself needs
  to get built static. It has been mentioned before and was again brought to
  our attention by Nathanael Nerode who filed debian bug report #405226
  (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405226).

Daniel (29 December 2006)
- Make curl_easy_duphandle() set the magic number in the new handle.

Daniel (22 December 2006)
- Robert Foreman provided a prime example snippet showing how libcurl would
  get confused and not acknowledge the 'no_proxy' variable properly once it
  had used the proxy and you re-used the same easy handle. I made sure the
  proxy name is properly stored in the connect struct rather than the
  sessionhandle/easy struct.

- David McCreedy fixed a bad call to getsockname() that wrongly used a size_t
  variable to point to when it should be a socklen_t.

- When setting a proxy with environment variables and (for example) running
  'curl [URL]' with a URL without a protocol prefix, curl would not send a
  correct request as it failed to add the protocol prefix.

Daniel (21 December 2006)
- Robson Braga Araujo reported bug #1618359
  (https://curl.haxx.se/bug/view.cgi?id=1618359) and subsequently provided a
  patch for it: when downloading 2 zero byte files in a row, curl 7.16.0
  enters an infinite loop, while curl 7.16.1-20061218 does one additional
  unnecessary request.

  Fix: During the "Major overhaul introducing http pipelining support and
  shared connection cache within the multi handle." change, headerbytecount
  was moved to live in the Curl_transfer_keeper structure. But that structure
  is reset in the Transfer method, losing the information that we had about
  the header size. This patch moves it back to the connectdata struct.

Daniel (16 December 2006)
- Brendan Jurd provided a fix that now prevents libcurl from getting a SIGPIPE
  during certain conditions when GnuTLS is used.

Daniel (11 December 2006)
- Alexey Simak found out that when doing FTP with the multi interface and
  something went wrong like it got a bad response code back from the server,
  libcurl would leak memory. Added test case 538 to verify the fix.

  I also noted that the connection would get cached in that case, which
  doesn't make sense since it cannot be re-use when the authentication has
  failed. I fixed that issue too at the same time, and also that the path
  would be "remembered" in vain for cases where the connection was about to
  get closed.

Daniel (6 December 2006)
- Sebastien Willemijns reported bug #1603712
  (https://curl.haxx.se/bug/view.cgi?id=1603712) which is about connections
  getting cut off prematurely when --limit-rate is used. While I found no such
  problems in my tests nor in my reading of the code, I found that the
  --limit-rate code was severly flawed (since it was moved into the lib, since
  7.15.5) when used with the easy interface and it didn't work as documented
  so I reworked it somewhat and now it works for my tests.

Daniel (5 December 2006)
- Stefan Krause pointed out a compiler warning with a picky MSCV compiler when
  passing a curl_off_t argument to the Curl_read_rewind() function which takes
  an size_t argument. Curl_read_rewind() also had debug code left in it and it
  was put in a different source file with no good reason when only used from
  one single spot.

- Sh Diao reported that CURLOPT_CLOSEPOLICY doesn't work, and indeed, there is
  no code present in the library that receives the option. Since it was not
  possible to use, we know that no current users exist and thus we simply
  removed it from the docs and made the code always use the default path of
  the code.

- Jared Lundell filed bug report #1604956
  (https://curl.haxx.se/bug/view.cgi?id=1604956) which identified setting
  CURLOPT_MAXCONNECTS to zero caused libcurl to SIGSEGV. Starting now, libcurl
  will always internally use no less than 1 entry in the connection cache.

- Sh Diao reported that CURLOPT_FORBID_REUSE no works, and indeed it broke in
  the 7.16.0 release.

- Martin Skinner brought back bug report #1230118 to haunt us once again.
  (https://curl.haxx.se/bug/view.cgi?id=1230118) curl_getdate() did not work
  properly for all input dates on Windows. It was mostly seen on some TZ time
  zones using DST. Luckily, Martin also provided a fix.

- Alexey Simak filed bug report #1600447
  (https://curl.haxx.se/bug/view.cgi?id=1600447) in which he noted that active
  FTP connections don't work with the multi interface. The problem is here
  that the multi interface state machine has a state during which it can wait
  for the data connection to connect, but the active connection is not done in
  the same step in the sequence as the passive one is so it doesn't quite work
  for active. The active FTP code still use a blocking function to allow the
  remote server to connect.

  The fix (work-around is a better word) for this problem is to set the
  boolean prematurely that the data connection is completed, so that the "wait
  for connect" phase ends at once.

  The proper fix, left for the future, is of course to make the active FTP
  case to act in a non-blocking way too.

- Matt Witherspoon fixed a problem case when the CPU load went to 100% when a
  HTTP upload was disconnected:

  "What appears to be happening is that my system (Linux 2.6.17 and 2.6.13) is
  setting *only* POLLHUP on poll() when the conditions in my previous mail
  occur. As you can see, select.c:Curl_select() does not check for POLLHUP. So
  basically what was happening, is poll() was returning immediately (with
  POLLHUP set), but when Curl_select() looked at the bits, neither POLLERR or
  POLLOUT was set. This still caused Curl_readwrite() to be called, which
  quickly returned. Then the transfer() loop kept continuing at full speed
  forever."

Daniel (1 December 2006)
- Toon Verwaest reported that there are servers that send the Content-Range:
  header in a third, not suppported by libcurl, format and we agreed that we
  could make the parser more forgiving to accept all the three found
  variations.

Daniel (25 November 2006)
- Venkat Akella found out that libcurl did not like HTTP responses that simply
  responded with a single status line and no headers nor body. Starting now, a
  HTTP response on a persistent connection (i.e not set to be closed after the
  response has been taken care of) must have Content-Length or chunked
  encoding set, or libcurl will simply assume that there is no body.

  To my horror I learned that we had no less than 57(!) test cases that did bad
  HTTP responses like this, and even the test http server (sws) responded badly
  when queried by the test system if it is the test system. So although the
  actual fix for the problem was tiny, going through all the newly failing test
  cases got really painful and boring.

Daniel (24 November 2006)
- James Housley did lots of work and introduced SFTP downloads.

Daniel (13 November 2006)
- Ron in bug #1595348 (https://curl.haxx.se/bug/view.cgi?id=1595348) pointed
  out a stack overwrite (and the corresponding fix) on 64bit Windows when
  dealing with HTTP chunked encoding.

Daniel (9 November 2006)
- Nir Soffer updated libcurl.framework.make:
  o fix symlinks, should link to Versions, not to ./Versions
  o indentation improvments

- Dmitriy Sergeyev found a SIGSEGV with his test04.c example posted on 7 Nov
  2006. It turned out we wrongly assumed that the connection cache was present
  when tearing down a connection.

- Ciprian Badescu found a SIGSEGV when doing multiple TFTP transfers using the
  multi interface, but I could also repeat it doing multiple sequential ones
  with the easy interface. Using Ciprian's test case, I could fix it.

Daniel (8 November 2006)
- Bradford Bruce reported that when setting CURLOPT_DEBUGFUNCTION without
  CURLOPT_VERBOSE set to non-zero, you still got a few debug messages from the
  SSL handshake. This is now stopped.

Daniel (7 November 2006)
- Olaf fixed a leftover problem with the CONNECT fix of his that would leave a
  wrong error message in the error message buffer.

Daniel (3 November 2006)
- Olaf Stueben provided a patch that I edited slightly. It fixes the notorious
  KNOWN_BUGS #25, which happens when a proxy closes the connection when
  libcurl has sent CONNECT, as part of an authentication negotiation. Starting
  now, libcurl will re-connect accordingly and continue the authentication as
  it should.

Daniel (2 November 2006)
- James Housley brought support for SCP transfers, based on the libssh2 library
  for the actual network protocol stuff.

  Added these new curl_easy_setopt() options:

    CURLOPT_SSH_AUTH_TYPES
    CURLOPT_SSH_PUBLIC_KEYFILE
    CURLOPT_SSH_PRIVATE_KEYFILE

Version 7.16.0 (30 October 2006)

Daniel (25 October 2006)
- Fixed CURLOPT_FAILONERROR to return CURLE_HTTP_RETURNED_ERROR even for the
  case when 401 or 407 are returned, *IF* no auth credentials have been given.
  The CURLOPT_FAILONERROR option is not possible to make fool-proof for 401
  and 407 cases when auth credentials is given, but we've now covered this
  somewhat more.

  You might get some amounts of headers transferred before this situation is
  detected, like for when a "100-continue" is received as a response to a
  POST/PUT and a 401 or 407 is received immediately afterwards.

  Added test 281 to verify this change.

Daniel (23 October 2006)
- Ravi Pratap provided a major update with pipelining fixes. We also no longer
  re-use connections (for pipelining) before the name resolving is done.

Daniel (21 October 2006)
- Nir Soffer made the tests/libtest/Makefile.am use a proper variable for all
  the single test applications' link and dependences, so that you easier can
  override those from the command line when using make.

- Armel Asselin separated CA cert verification problems from problems with
  reading the (local) CA cert file to let users easier pinpoint the actual
  problem. CURLE_SSL_CACERT_BADFILE (77) is the new libcurl error code.

Daniel (18 October 2006)
- Removed the "protocol-guessing" for URLs with host names starting with FTPS
  or TELNET since they are practically non-existant. This leaves us with only
  three different prefixes that would assume the protocol is anything but
  HTTP, and they are host names starting with "ftp.", "dict." or "ldap.".

Daniel (17 October 2006)
- Bug report #1579171 pointed out code flaws detected with "prefast", and they
  were 1 - a too small memory clear with memset() in the threaded resolver and
  2 - a range of potentially bad uses of the ctype family of is*() functions
  such as isdigit(), isalnum(), isprint() and more. The latter made me switch
  to using our own set of these functions/macros using uppercase letters, and
  with some extra set of crazy typecasts to avoid mistakingly passing in
  negative numbers to the underlying is*() functions.

- With Jeff Pohlmeyer's help, I fixed the expire timer when using
  curl_multi_socket() during name resolves with c-ares and the LOW_SPEED
  options now work fine with curl_multi_socket() as well.

Daniel (16 October 2006)
- Added a check in configure that simply tries to run a program (not when
  cross-compiling) in order to detect problems with run-time libraries that
  otherwise would occur when the sizeof tests for curl_off_t would run and
  thus be much more confusing to users. The check of course should run after
  all lib-checks are done and before any other test is used that would run an
  executable built for testing-purposes.

Dan F (13 October 2006)
- The tagging of application/x-www-form-urlencoded POST body data sent
  to the CURLOPT_DEBUGFUNCTION callback has been fixed (it was erroneously
  included as part of the header).  A message was also added to the
  command line tool to show when data is being sent, enabled when
  --verbose is used.

Daniel (12 October 2006)
- Starting now, adding an easy handle to a multi stack that was already added
  to a multi stack will cause CURLM_BAD_EASY_HANDLE to get returned.

- Jeff Pohlmeyer has been working with the hiperfifo.c example source code,
  and while doing so it became apparent that the current timeout system for
  the socket API really was a bit awkward since it become quite some work to
  be sure we have the correct timeout set.

  Jeff then provided the new CURLMOPT_TIMERFUNCTION that is yet another
  callback the app can set to get to know when the general timeout time
  changes and thus for an application like hiperfifo.c it makes everything a
  lot easier and nicer. There's a CURLMOPT_TIMERDATA option too of course in
  good old libcurl tradition.

  Jeff has also updated the hiperfifo.c example code to use this news.

Daniel (9 October 2006)
- Bogdan Nicula's second test case (posted Sun, 08 Oct 2006) converted to test
  case 535 and it now runs fine. Again a problem with the pipelining code not
  taking all possible (error) conditions into account.

Daniel (6 October 2006)
- Bogdan Nicula's hanging test case (posted Wed, 04 Oct 2006) was converted to
  test case 533 and the test now runs fine.

Daniel (4 October 2006)
- Dmitriy Sergeyev provided an example source code that crashed CVS libcurl
  but that worked nicely in 7.15.5. I converted it into test case 532 and
  fixed the problem.

Daniel (29 September 2006)
- Removed a few other no-longer present options from the header file.

- Support for FTP third party transfers was removed. Here's why:

  o The recent multi interface changes broke it and the design of the 3rd party
    transfers made it very hard to fix the problems
  o It was still blocking and thus nasty for the multi interface
  o It was a lot of extra code for a very rarely used feature
  o It didn't use the same code as for "plain" FTP transfers, so it didn't work
    fine for IPv6 and it didn't properly re-use connections and more
  o There's nobody around who's willing to work on and improve the existing
    code

  This does not mean that third party transfers are banned forever, only that
  they need to be done better if they are to be re-added in the future.

  The CURLOPT_SOURCE_* options are removed from the lib and so are the --3p*
  options from the command line tool. For this reason, I also bumped the
  version info for the lib.

Daniel (28 September 2006)
- Reported in #1561470 (https://curl.haxx.se/bug/view.cgi?id=1561470), libcurl
  would crash if a bad function sequence was used when shutting down after
  using the multi interface (i.e using easy_cleanup after multi_cleanup) so
  precautions have been added to make sure it doesn't any more - test case 529
  was added to verify.

Daniel (27 September 2006)
- The URL in the cookie jar file is now changed since it was giving a 404.
  Reported by Timothy Stone. The new URL will take the visitor to a curl web
  site mirror with the document.

Daniel (24 September 2006)
- Bernard Leak fixed configure --with-gssapi-libs.

- Cory Nelson made libcurl use the WSAPoll() function if built for Windows
  Vista (_WIN32_WINNT >= 0x0600)

Daniel (23 September 2006)
- Mike Protts added --ftp-ssl-control to make curl use FTP-SSL, but only
  encrypt the control connection and use the data connection "plain".

- Dmitriy Sergeyev provided a patch that made the SOCKS[45] code work better
  as it now will read the full data sent from servers. The SOCKS-related code
  was also moved to the new lib/socks.c source file.

Daniel (21 September 2006)
- Added test case 531 in an attempt to repeat bug report #1561470
  (https://curl.haxx.se/bug/view.cgi?id=1561470) that is said to crash when an
  FTP upload fails with the multi interface. It did not, but I made a failed
  upload still assume the control connection to be fine.

Daniel (20 September 2006)
- Armel Asselin fixed problems when you gave a proxy URL with user name and
  empty password or no password at all. Test case 278 and 279 were added to
  verify.

Daniel (12 September 2006)
- Added docs/examples/10-at-a-time.c by Michael Wallner

- Added docs/examples/hiperfifo.c by Jeff Pohlmeyer

Daniel (11 September 2006)
- Fixed my breakage from earlier today so that doing curl_easy_cleanup() on a
  handle that is part of a multi handle first removes the handle from the
  stack.

- Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL
  session-ID re-use on demand since there obviously are broken servers out
  there that misbehave with session-IDs used.

- Jeff Pohlmeyer presented a *multi_socket()-using program that exposed a
  problem with it (SIGSEGV-style). It clearly showed that the existing
  socket-state and state-difference function wasn't good enough so I rewrote
  it and could then re-run Jeff's program without any crash. The previous
  version clearly could miss to tell the application when a handle changed
  from using one socket to using another.

  While I was at it (as I could use this as a means to track this problem
  down), I've now added a 'magic' number to the easy handle struct that is
  inited at curl_easy_init() time and cleared at curl_easy_cleanup() time that
  we can use internally to detect that an easy handle seems to be fine, or at
  least not closed or freed (freeing in debug builds fill the area with 0x13
  bytes but in normal builds we can of course not assume any particular data
  in the freed areas).

Daniel (9 September 2006)
- Michele Bini fixed how the hostname is put in NTLM packages. As servers
  don't expect fully qualified names we need to cut them off at the first dot.

- Peter Sylvester cleaned up and fixed the getsockname() uses in ftp.c. Some
  of them can be completetly removed though...

Daniel (6 September 2006)
- Ravi Pratap and I have implemented HTTP Pipelining support. Enable it for a
  multi handle using CURLMOPT_PIPELINING and all HTTP connections done on that
  handle will be attempted to get pipelined instead of done in parallell as
  they are performed otherwise.

  As a side-effect from this work, connections are now shared between all easy
  handles within a multi handle, so if you use N easy handles for transfers,
  each of them can pick up and re-use a connection that was previously used by
  any of the handles, be it the same or one of the others.

  This separation of the tight relationship between connections and easy
  handles is most noticable when you close easy handles that have been used in
  a multi handle and check amount of used memory or watch the debug output, as
  there are times when libcurl will keep the easy handle around for a while
  longer to be able to close it properly. Like for sending QUIT to close down
  an FTP connection.

  This is a major change.

Daniel (4 September 2006)
- Dmitry Rechkin (https://curl.haxx.se/bug/view.cgi?id=1551412) provided a
  patch that while not fixing things very nicely, it does make the SOCKS5
  proxy connection slightly better as it now acknowledges the timeout for
  connection and it no longer segfaults in the case when SOCKS requires
  authentication and you did not specify username:password.

Daniel (31 August 2006)
- Dmitriy Sergeyev found and fixed a multi interface flaw when using asynch
  name resolves. It could get stuck in the wrong state.

Gisle (29 August 2006)
- Added support for other MS-DOS compilers (desides djgpp). All MS-DOS
  compiler now uses the same config.dos file (renamed to config.h by
  make). libcurl now builds fine using Watcom and Metaware's High-C
  using the Watt-32 tcp/ip-stack.

Daniel (29 August 2006)
- David McCreedy added CURLOPT_SOCKOPTFUNCTION and CURLOPT_SOCKOPTDATA to
  allow applications to set their own socket options.

Daniel (25 August 2006)
- Armel Asselin reported that the 'running_handles' counter wasn't updated
  properly if you removed a "live" handle from a multi handle with
  curl_multi_remove_handle().

Daniel (22 August 2006)
- David McCreedy fixed a remaining mistake from the August 19 TYPE change.

- Peter Sylvester pointed out a flaw in the AllowServerConnect() in the FTP
  code when doing pure IPv6 EPRT connections.

Daniel (19 August 2006)
- Based on a patch by Armel Asselin, the FTP code no longer re-issues the TYPE
  command on subsequent requests on a re-used connection unless it has to.

- Armel Asselin fixed a crash in the FTP code when using SINGLECWD mode and
  files in the root directory.

- Andrew Biggs pointed out a "Expect: 100-continue" flaw where libcurl didn't
  send the whole request at once, even though the Expect: header was disabled
  by the application. An effect of this change is also that small (< 1024
  bytes) POSTs are now always sent without Expect: header since we deem it
  more costly to bother about that than the risk that we send the data in
  vain.

Daniel (9 August 2006)
- Armel Asselin made the CURLOPT_PREQUOTE option work fine even when
  CURLOPT_NOBODY is set true. PREQUOTE is then run roughly at the same place
  in the command sequence as it would have run if there would've been a
  transfer.

Daniel (8 August 2006)
- Fixed a flaw in the "Expect: 100-continue" treatment. If you did two POSTs
  on a persistent connection and allowed the first to use that header, you
  could not disable it for the second request.

Daniel (7 August 2006)
- Domenico Andreolfound a quick build error which happened because
  src/config.h.in was not a proper duplcate of lib/config.h.in which it
  should've been and this was due to the maketgz script not doing the cp
  properly.

Version 7.15.5 (7 August 2006)

Daniel (2 August 2006)
- Mark Lentczner fixed how libcurl was not properly doing chunked encoding
  if the header "Transfer-Encoding: chunked" was set by the application.
  https://curl.haxx.se/bug/view.cgi?id=1531838

Daniel (1 August 2006)
- Maciej Karpiuk fixed a crash that would occur if we passed Curl_strerror()
  an unknown error number on glibc systems.
  https://curl.haxx.se/bug/view.cgi?id=1532289

Daniel (31 July 2006)
- *ALERT* curl_multi_socket() and curl_multi_socket_all() got modified
  prototypes: they both now provide the number of running handles back to the
  calling function. It makes the functions resemble the good old
  curl_multi_perform() more and provides a nice way to know when the multi
  handle goes empty.

  ALERT2: don't use the curl_multi_socket*() functionality in anything
  production-like until I say it's somewhat settled, as I suspect there might
  be some further API changes before I'm done...

Daniel (28 July 2006)
- Yves Lejeune fixed so that replacing Content-Type: when doing multipart
  formposts work exactly the way you want it (and the way you'd assume it
  works).

Daniel (27 July 2006)
- David McCreedy added --ftp-ssl-reqd which makes curl *require* SSL for both
  control and data connection, as the existing --ftp-ssl option only requests
  it.

- [Hiper-related work] Added a function called curl_multi_assign() that will
  set a private pointer added to the internal libcurl hash table for the
  particular socket passed in to this function:

  CURLMcode curl_multi_assign(CURLM *multi_handle,
                              curl_socket_t sockfd,
                              void *sockp);

  'sockp' being a custom pointer set by the application to be associated with
  this socket. The socket has to be already existing and in-use by libcurl,
  like having already called the callback telling about its existance.

  The set hashp pointer will then be passed on to the callback in upcoming
  calls when this same socket is used (in the brand new 'socketp' argument).

Daniel (26 July 2006)
- Dan Nelson added the CURLOPT_FTP_ALTERNATIVE_TO_USER libcurl option and curl
  tool option named --ftp-alternative-to-user. It provides a mean to send a
  particular command if the normal USER/PASS approach fails.

- Michael Jerris added magic that builds lib/curllib.vcproj automatically for
  newer MSVC.

Daniel (25 July 2006)
- Georg Horn made the transfer timeout error message include more details.

Daniel (20 July 2006)
- David McCreedy fixed a build error when building libcurl with HTTP disabled,
  problem added with the curl_formget() patch.

Daniel (17 July 2006)
- Jari Sundell did some excellent research and bug tracking, figured out that
  we did wrong and patched it: When nodes were removed from the splay tree,
  and we didn't properly remove it from the splay tree when an easy handle was
  removed from a multi stack and thus we could wrongly leave a node in the
  splay tree pointing to (bad) memory.

Daniel (14 July 2006)
- David McCreedy fixed a flaw where the CRLF counter wasn't properly cleared
  for FTP ASCII transfers.

Daniel (8 July 2006)
- Ates Goral pointed out that libcurl's cookie parser did case insensitive
  string comparisons on the path which is incorrect and provided a patch that
  fixes this. I edited test case 8 to include details that test for this.

- Ingmar Runge provided a source snippet that caused a crash. The reason for
  the crash was that libcurl internally was a bit confused about who owned the
  DNS cache at all times so if you created an easy handle that uses a shared
  DNS cache and added that to a multi handle it would crash. Now we keep more
  careful internal track of exactly what kind of DNS cache each easy handle
  uses: None, Private (allocated for and used only by this single handle),
  Shared (points to a cache held by a shared object), Global (points to the
  global cache) or Multi (points to the cache within the multi handle that is
  automatically shared between all easy handles that are added with private
  caches).

Daniel (4 July 2006)
- Toshiyuki Maezawa fixed a problem where you couldn't override the
  Proxy-Connection: header when using a proxy and not doing CONNECT.

Daniel (24 June 2006)
- Michael Wallner added curl_formget(), which allows an application to extract
  (serialise) a previously built formpost (as with curl_formadd()).

Daniel (23 June 2006)
- Arve Knudsen found a flaw in curl_multi_fdset() for systems where
  curl_socket_t is unsigned (like Windows) that could cause it to wrongly
  return a max fd of -1.

Daniel (20 June 2006)
- Peter Silva introduced CURLOPT_MAX_SEND_SPEED_LARGE and
  CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed
  to send or receive data. This kind of adds the the command line tool's
  option --limit-rate to the library.

  The rate limiting logic in the curl app is now removed and is instead
  provided by libcurl itself. Transfer rate limiting will now also work for -d
  and -F, which it didn't before.

Daniel (19 June 2006)
- Made -K on a file that couldn't be read cause a warning to be displayed.

Daniel (13 June 2006)
- Dan Fandrich implemented --enable-hidden-symbols configure option to enable
  -fvisibility=hidden on gcc >= 4.0.  This reduces the size of the libcurl
  binary and speeds up dynamic linking by hiding all the internal symbols from
  the symbol table.

Version 7.15.4 (12 June 2006)

Daniel (8 June 2006)
- Brian Dessent fixed the code for cygwin in three distinct ways:

  The first modifies {lib,src}/setup.h to not include the winsock headers
  under Cygwin.  This fixes the reported build problem.  Cygwin attempts as
  much as possible to emulate a posix environment under Windows.  This means
  that WIN32 is *not* #defined and (to the extent possible) everything is done
  as it would be on a *ix type system.  Thus <sys/socket.h> is the proper
  include, and even though winsock2.h is present, including it just introduces
  a whole bunch of incompatible socket API stuff.

  The second is a patch I've included in the Cygwin binary packages for a
  while.  It skips two unnecessary library checks (-lwinmm and -lgdi32).  The
  checks are innocuous and they do succeed, but they pollute LIBS with
  unnecessary stuff which gets recorded as such in the libcurl.la file, which
  brings them into the build of any libcurl-downstream.  As far as I know
  these libs are really only necessary for mingw, so alternatively they could
  be designed to only run if $host matches *-*-mingw* but I took the safer
  route of skipping them for *-*-cygwin*.

  The third patch replaces all uses of the ancient and obsolete __CYGWIN32__
  with __CYGWIN__. Ref: <https://cygwin.com/ml/cygwin/2003-09/msg01520.html>.

Daniel (7 June 2006)
- Mikael Sennerholm provided a patch that added NTLM2 session response support
  to libcurl. The 21 NTLM test cases were again modified to comply...

Daniel (27 May 2006)
- Óscar Morales Vivó updated the libcurl.framework.make file.

Daniel (26 May 2006)
- Olaf Stüben fixed a bug that caused Digest authentication with md5-sess to
  fail. When using the md5-sess, the result was not Md5 encoded and Base64
  transformed.

Daniel (25 May 2006)
- Michael Wallner provided a patch that allows "SESS" to be set with
  CURLOPT_COOKIELIST, which then makes all session cookies get cleared.

Daniel (24 May 2006)
- Tor Arntsen made test 271 run fine again since the TFTP path fix.

Daniel (23 May 2006)
- Martin Michlmayr filed debian bug report #367954, but the same error also
  showed up in the autobuilds. It seems a rather long-since introduced shell
  script flaw in the configure script suddenly was detected by the bash
  version in Debian Unstable. It had previously passed undetected by all
  shells used so far...

- David McCreedy updated lib/config-tpf.h

Daniel (11 May 2006)
- Fixed the configure's check for old-style SSLeay headers since I fell over a
  case with a duplicate file name (a krb4 implementation with an err.h
  file). I converted the check to manually make sure three of the headers are
  present before considering them fine.

- David McCreedy provided a fix for CURLINFO_LASTSOCKET that does extended
  checks on the to-be-returned socket to make sure it truly seems to be alive
  and well. For SSL connection it (only) uses OpenSSL functions.

Daniel (10 May 2006)
- Fixed DICT in two aspects:

  1 - allow properly URL-escaped words, like using %20 for spaces

  2 - properly escape certain letters within a word to comply to the RFC2229

Daniel (9 May 2006)
- Andreas Ntaflos reported a bug in libcurl.m4: When configuring my GNU
  autotools project, which optionally (default=yes) uses libcurl on a system
  without a (usable) libcurl installation, but not specifying
  `--without-libcurl', configure determines correctly that no libcurl is
  available, however, the LIBCURL variable gets expanded to `LIBCURL = -lcurl'
  in the resulting Makefiles.

  David Shaw fixed the flaw.

- Robson Braga Araujo fixed two problems in the recently added non-blocking SSL
  connects. The state machine was not reset properly so that subsequent
  connects using the same handle would fail, and there were two memory leaks.

- Robson Braga Araujo fixed a memory leak when you added an easy handle to a
  multi stack and that easy handle had already been used to do one or more
  easy interface transfers, as then the code threw away the previously used
  DNS cache without properly freeing it.

Daniel (8 May 2006)
- Dan Fandrich went over the TFTP code and he pointed out and fixed numerous
  problems:

  * The received file is corrupted when a packet is lost and retransmitted
    (this is a serious problem!)

  * Transmitting a file aborts if a block is lost and retransmitted

  * Data is stored in the wrong location in the buffer for uploads, so uploads
    always fail (I don't see how it could have ever worked, but it did on x86
    at least)

  * A number of calls are made to strerror instead of Curl_strerror, making
    the code not thread safe

  * There are references to errno instead of Curl_sockerrno(), causing
    incorrect error messages on Windows

  * The file name includes a leading / which violates RFC3617. Doing something
    similar to ftp, where two slashes after the host name means an absolute
    reference seems a reasonable extension to fix this.

  * Failures in EBCDIC conversion are not propagated up to the caller but are
    silently ignored

- Fixed known bug #28. The TFTP code no longer assumes a packed struct and
  thus works reliably on more platforms.

Daniel (5 May 2006)
- Roland Blom filed bug report #1481217
  (https://curl.haxx.se/bug/view.cgi?id=1481217), with follow-ups by Michele
  Bini and David Byron. libcurl previously wrongly used GetLastError() on
  windows to get error details after socket-related function calls, when it
  really should use WSAGetLastError() instead.

  When changing to this, the former function Curl_ourerrno() is now instead
  called Curl_sockerrno() as it is necessary to only use it to get errno from
  socket-related functions as otherwise it won't work as intended on Windows.

Daniel (4 May 2006)
- Mark Eichin submitted bug report #1480821
  (https://curl.haxx.se/bug/view.cgi?id=1480821) He found and identified a
  problem with how libcurl dealt with GnuTLS and a case where gnutls returned
  GNUTLS_E_AGAIN indicating it would block. It would then return an unexpected
  return code, making Curl_ssl_send() confuse the upper layer - causing random
  28 bytes trash data to get inserted in the transfered stream.

  The proper fix was to make the Curl_gtls_send() function return the proper
  return codes that the callers would expect. The Curl_ossl_send() function
  already did this.

Daniel (2 May 2006)
- Added a --checkfor option to curl-config to allow users to easier
  write for example shell scripts that test for the presence of a
  new-enough libcurl version. If --checkfor is given a version string
  newer than what is currently installed, curl-config will return a
  non-zero exit code and output a string about the unfulfilled
  requirement.

Daniel (26 April 2006)
- David McCreedy brought initial line end conversions when doing FTP ASCII
  transfers. They are done on non-windows systems and translate CRLF to LF.

  I modified the 15 LIST-using test cases accordingly. The downside is that now
  we'll have even more trouble to get the tests to run on Windows since they
  should get CRLF newlines left intact which the *nix versions don't. I figure
  the only sane thing to do is to add some kind of [newline] macro for the test
  case files and have them expanded to the proper native line ending when the
  test cases are run. This is however left to implement.

Daniel (25 April 2006)
- Paul Querna fixed libcurl to better deal with deflate content encoding
  when the stream (wrongly) lacks a proper zlib header. This seems to be the
  case on too many actual server implementations.

Daniel (21 April 2006)
- Ale Vesely fixed CURLOPT_INTERFACE when using a hostname.

Daniel (19 April 2006)
- Based on previous info from Tor Arntsen, I made configure detect the Intel
  ICC compiler to add a compiler option for it, in order for configure to
  properly be able to detect function prototypes.

- Robson Braga Araujo provided a patch that makes libcurl less eager to close
  the control connection when using FTP, for example when you remove an easy
  handle from a multi stack.

- Applied a patch by Ates Goral and Katie Wang that corrected my bad fix
  attempt from April 10.

Daniel (11 April 2006)
- #1468330 (https://curl.haxx.se/bug/view.cgi?id=1468330) pointed out a bad
  typecast in the curl tool leading to a crash with (64bit?) VS2005 (at least)
  since the struct timeval field tv_sec is an int while time_t is 64bit.

Daniel (10 April 2006)
- Ates Goral found out that if you specified both CURLOPT_CONNECTTIMEOUT and
  CURLOPT_TIMEOUT, the _longer_ time would wrongly be used for the SSL
  connection time-out!

- I merged my hiper patch (https://curl.haxx.se/libcurl/hiper/) into the main
  sources. See the lib/README.multi_socket for implementation story with
  details. Don't expect it to work fully yet. I don't intend to blow any
  whistles or ring any bells about it until I'm more convinced it works at
  least somewhat reliably.

Daniel (7 April 2006)
- David McCreedy's EBCDIC and TPF changes. Three new curl_easy_setopt()
  options (callbacks) were added:

  CONV_FROM_NETWORK_FUNCTION
  CONV_TO_NETWORK_FUNCTION
  CONV_FROM_UTF8_FUNCTION

Daniel (5 April 2006)
- Michele Bini modified the NTLM code to work for his "weird IIS case"
  (https://curl.haxx.se/mail/lib-2006-02/0154.html) by adding the NTLM hash
  function in addition to the LM one and making some other adjustments in the
  order the different parts of the data block are sent in the Type-2 reply.
  Inspiration for this work was taken from the Firefox NTLM implementation.

  I edited the existing 21(!) NTLM test cases to run fine with these news. Due
  to the fact that we now properly include the host name in the Type-2 message
  the test cases now only compare parts of that chunk.

Daniel (28 March 2006)
- #1451929 (https://curl.haxx.se/bug/view.cgi?id=1451929) detailed a bug that
  occurred when asking libcurl to follow HTTP redirects and the original URL
  had more than one question mark (?). Added test case 276 to verify.

Daniel (27 March 2006)
- David Byron found a problem multiple -d options when libcurl was built with
  --enable-debug, as then curl used free() on memory allocated both with
  normal malloc() and with libcurl-provided functions, when the latter MUST be
  freed with curl_free() in debug builds.

Daniel (26 March 2006)
- Tor Arntsen figured out that TFTP was broken on a lot of systems since we
  called bind() with a too big argument in the 3rd parameter and at least
  Tru64, AIX and IRIX seem to be very picky about it.

Daniel (21 March 2006)
- David McCreedy added CURLINFO_FTP_ENTRY_PATH.

- Xavier Bouchoux made the SSL connection non-blocking for the multi interface
  (when using OpenSSL).

- Tor Arntsen fixed the AIX Toolbox RPM spec

Daniel (20 March 2006)
- David McCreedy fixed libcurl to no longer ignore AUTH failures and now it
  reacts properly according to the CURLOPT_FTP_SSL setting.

- Dan Fandrich fixed two TFTP problems: Fixed a bug whereby a received file
  whose length was a multiple of 512 bytes could have random garbage
  appended. Also, stop processing TFTP packets which are too short to be
  legal.

- Ilja van Sprundel reported a possible crash in the curl tool when using
  "curl hostwithoutslash -d data -G"

Version 7.15.3 (20 March 2006)

Daniel (20 March 2006)
- VULNERABILITY reported to us by Ulf Harnhammar.

  libcurl uses the given file part of a TFTP URL in a manner that allows a
  malicious user to overflow a heap-based memory buffer due to the lack of
  boundary check.

  This overflow happens if you pass in a URL with a TFTP protocol prefix
  ("tftp://"), using a valid host and a path part that is longer than 512
  bytes.

  The affected flaw can be triggered by a redirect, if curl/libcurl is told to
  follow redirects and an HTTP server points the client to a tftp URL with the
  characteristics described above.

  The Common Vulnerabilities and Exposures (CVE) project has assigned the name
  CVE-2006-1061 to this issue.

Daniel (16 March 2006)
- Tor Arntsen provided a RPM spec file for AIX Toolbox, that now is included
  in the release archive.

Daniel (14 March 2006)
- David McCreedy fixed:

  a bad SSL error message when OpenSSL certificates are verified fine.

  a missing return code assignment in the FTP code

Daniel (7 March 2006)
- Markus Koetter filed debian bug report #355715 which identified a problem
  with the multi interface and multi-part formposts. The fix from February
  22nd could make the Curl_done() function get called twice on the same
  connection and it was not designed for that and thus tried to call free() on
  an already freed memory area!

- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL
  is used properly.

Daniel (6 March 2006)
- Lots of users on Windows have reported getting the "SSL: couldn't set
  callback" error message so I've now made the setting of that callback not be
  as critical as before. The function is only used for additional loggging/
  trace anyway so a failure just means slightly less data. It should still be
  able to proceed and connect fine to the server.

Daniel (4 March 2006)
- Thomas Klausner provided a patch written by Todd Vierling in bug report
  #1442471 that fixes a build problem on Interix.

Daniel (2 March 2006)
- FTP upload without a file name part in the URL now causes
  curl_easy_perform() to return CURLE_URL_MALFORMAT. Previously it allowed the
  upload but named the file "(nil)" (without the quotes). Test case 524
  verifies.

- Added a check for getprotobyname in configure so that it'll be used, thanks
  to Gisle Vanem's change the other day.

Daniel (28 February 2006)
- Dan Fandrich prevented curl from getting stuck in an endless loop in case we
  are out of file handles very early in curl's code where it makes sure that
  0, 1 and 2 aren't gonna be used by the lib for transfers.

Daniel (27 February 2006)
- Marty Kuhrt pointed out that there were two VMS-specific files missing in
  the release archive.

Version 7.15.2 (27 February 2006)

Daniel (22 February 2006)
- Lots of work and analysis by "xbx___" in bug #1431750
  (https://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
  different but related bugs:

  1) Removing an easy handle from a multi handle before the transfer is done
     could leave a connection in the connection cache for that handle that is
     in a state that isn't suitable for re-use. A subsequent re-use could then
     read from a NULL pointer and segfault.

  2) When an easy handle was removed from the multi handle, there could be an
     outstanding c-ares DNS name resolve request. When the response arrived,
     it caused havoc since the connection struct it "belonged" to could've
     been freed already.

  Now Curl_done() is called when an easy handle is removed from a multi handle
  pre-maturely (that is, before the transfer was complteted). Curl_done() also
  makes sure to cancel all (if any) outstanding c-ares requests.

Daniel (21 February 2006)
- Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
  type to the already provided type CURLPROXY_SOCKS4.

  I added a --socks4 option that works like the current --socks5 option but
  instead use the socks4 protocol.

Daniel (20 February 2006)
- Shmulik Regev fixed an issue with multi-pass authentication and compressed
  content when libcurl didn't honor the internal ignorebody flag.

Daniel (18 February 2006)
- Ulf Härnhammar fixed a format string (printf style) problem in the Negotiate
  code. It should however not be the cause of any troubles. He also fixed a
  few similar problems in the HTTP test server code.

Daniel (17 February 2006)
- Shmulik Regev provided a fix for the DNS cache when using short life times,
  as previously it could be holding on to old cached entries longer than
  requested.

Daniel (11 February 2006)
- Karl Moerder added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options
  that an app can use to let libcurl only connect to a remote host and then
  extract the socket from libcurl. libcurl will then not attempt to do any
  transfer at all after the connect is done.

- Kent Boortz improved the configure check for GnuTLS to properly set LIBS
  instead of LDFLAGS.

Daniel (8 February 2006)
- Philippe Vaucher provided a brilliant piece of test code that show a problem
  with re-used FTP connections. If the second request on the same connection
  was set not to fetch a "body", libcurl could get confused and consider it an
  attempt to use a dead connection and would go acting mighty strange.

Daniel (2 February 2006)
- Make --limit-rate [num] mean bytes. It used to be that but it broke in my
  change done in November 2005.

Daniel (30 January 2006)
- Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the
  curl tool with --local-port. Plain and simply set the range of ports to bind
  the local end of connections to. Implemented on to popular demand.

- Based on an error report by Philippe Vaucher, we no longer count a retried
  connection setup as a follow-redirect. It turns out 1) this fails when a FTP
  connection is re-setup and 2) it does make the max-redirs counter behave
  wrong.

Daniel (24 January 2006)
- Michal Marek provided a patch for FTP that makes libcurl continue to try
  PASV even after EPSV returned a positive response code, if libcurl failed to
  connect to the port number the EPSV response said. Obviously some people are
  going through protocol-sensitive firewalls (or similar) that don't
  understand EPSV and then they don't allow the second connection unless PASV
  was used. This also called for a minor fix of test case 238.

Daniel (20 January 2006)
- Duane Cathey was one of our friends who reported that curl -P [IP]
  (CURLOPT_FTPPORT) didn't work for IPv6-enabed curls if the IP wasn't a
  "native" IP while it works fine for IPv6-disabled builds!

  In the process of fixing this, I removed the support for LPRT since I can't
  think of many reasons to keep doing it and asking on the mailing list didn't
  reveal anyone else that could either. The code that sends EPRT and PORT is
  now also a lot simpler than before (IMHO).

Daniel (19 January 2006)
- Jon Turner pointed out that doing -P [hostname] (CURLOPT_FTPPORT) with curl
  (built IPv4-only) didn't work.

Daniel (18 January 2006)
- As reported in bug #1408742 (https://curl.haxx.se/bug/view.cgi?id=1408742),
  the configure script complained about a missing "missing" script if you ran
  configure within a path whose name included one or more spaces. This is due
  to a flaw in automake (1.9.6 and earlier). I've now worked around it by
  including an "overloaded" version of the AM_MISSING_HAS_RUN script that'll
  be used instead of the one automake ships with. This kludge needs to be
  removed once we get an automake version with this problem corrected.
  Possibly we'll then need to convert this into a kludge depending on what
  automake version that is used and that is gonna be painful and I don't even
  want to think about that now...!

Daniel (17 January 2006)
- David Shaw: Here is the latest libcurl.m4 autoconf tests. It is updated with
  the latest features and protocols that libcurl supports and has a minor fix
  to better deal with the obscure case where someone has more than one libcurl
  installed at the same time.

Daniel (16 January 2006)
- David Shaw finally removed all traces of Gopher and we are now officially
  not supporting it. It hasn't been functioning for years anyway, so this is
  just finally stating what already was true. And a cleanup at the same time.

- Bryan Henderson turned the 'initialized' variable for curl_global_init()
  into a counter, and thus you can now do multiple curl_global_init() and you
  are then supposed to do the same amount of calls to curl_global_cleanup().
  Bryan has also updated the docs accordingly.

Daniel (13 January 2006)
- Andrew Benham fixed a race condition in the test suite that could cause the
  test script to kill all processes in the current process group!

Daniel (12 January 2006)
- Michael Jahn:

  Fixed FTP_SKIP_PASV_IP and FTP_USE_EPSV to "do right" when used on FTP thru
  HTTP proxy.

  Fixed PROXYTUNNEL to work fine when you do ftp through a proxy.  It would
  previously overwrite internal memory and cause unpredicted behaviour!

Daniel (11 January 2006)
- I decided to document the "secret option" here now, as I've received *NO*
  feedback at all on my mailing list requests from November 2005:

  I'm looking for feedback and comments. I added some experimental code the
  other day, that allows a libcurl user to select what method libcurl should
  use to reach a file on a FTP(S) server.

  This functionality is available in CVS code and in recent daily snapshots.

  Let me explain...

  The current name for the option is CURLOPT_FTP_FILEMETHOD (--ftp-method for
  the command line tool) and you set it to a long (there are currenly no
  defines for the argument values, just plain numericals). You can set three
  different "methods" that do this:

  1 multicwd - like today, curl will do a single CWD operation for each path
           part in the given URL. For deep hierarchies this means very many
           commands. This is how RFC1738 says it should be done. This is the
           default.

  2 nocwd - no CWD at all is done, curl will do SIZE, RETR, STOR etc and give
           a full path to the server.

  3 singlecwd - make one CWD with the full target directory and then operate
            on the file "normally".

  (With the command line tool you do --ftp-method [METHOD], where [METHOD] is
  one of "multicwd", "nocwd" or "singlecwd".)

  What feedback I'm interested in:

  1 - Do they work at all? Do you find servers where one of these don't work?

  2 - What would proper names for the option and its arguments be, if we
      consider this feature good enough to get included and documented in
      upcoming releases?

  3 - Should we make libcurl able to "walk through" these options in case of
      (path related) failures, or should it fail and let the user redo any
      possible retries?

  (This option is not documented in any man page just yet since I'm not sure
  these names will be used or if the functionality will end up exactly like
  this.  And for the same reasons we have no test cases for these yet.)

Daniel (10 January 2006)
- When using a bad path over FTP, as in when libcurl couldn't CWD into all
  given subdirs, libcurl would still "remember" the full path as if it is the
  current directory libcurl is in so that the next curl_easy_perform() would
  get really confused if it tried the same path again - as it would not issue
  any CWD commands at all, assuming it is already in the "proper" dir.

  Starting now, a failed CWD command sets a flag that prevents the path to be
  "remembered" after returning.

Daniel (7 January 2006)
- Michael Jahn fixed so that the second CONNECT when doing FTP over a HTTP
  proxy actually used a new connection and not sent the second request on the
  first socket!

Daniel (6 January 2006)
- Alexander Lazic made the buildconf run the buildconf in the ares dir if that
  is present instead of trying to mimic that script in curl's buildconf
  script.

Daniel (3 January 2006)
- Andres Garcia made the TFTP test server build with mingw.
Daniel (16 December 2005)
- Jean Jacques Drouin pointed out that you could only have a user name or
  password of 127 bytes or less embedded in a URL, where actually the code
  uses a 255 byte buffer for it! Modified now to use the full buffer size.

Daniel (12 December 2005)
- Dov Murik corrected the HTTP_ONLY define to disable the TFTP support properly

Version 7.15.1 (7 December 2005)

Daniel (6 December 2005)
- Full text here: https://curl.haxx.se/docs/adv_20051207.html Pointed out by
  Stefan Esser.

  VULNERABILITY

  libcurl's URL parser function can overflow a malloced buffer in two ways, if
  given a too long URL.

  These overflows happen if you

  1 - pass in a URL with no protocol (like "http://") prefix, using no slash
      and the string is 256 bytes or longer. This leads to a single zero byte
      overflow of the malloced buffer.

  2 - pass in a URL with only a question mark as separator (no slash) between
      the host and the query part of the URL. This leads to a single zero byte
      overflow of the malloced buffer.

  Both overflows can be made with the same input string, leading to two single
  zero byte overwrites.

  The affected flaw cannot be triggered by a redirect, but the long URL must
  be passed in "directly" to libcurl. It makes this a "local" problem. Of
  course, lots of programs may still pass in user-provided URLs to libcurl
  without doing much syntax checking of their own, allowing a user to exploit
  this vulnerability.

  There is no known exploit at the time of this writing.


Daniel (2 December 2005)
- Jamie Newton pointed out that libcurl's file:// code would close() a zero
  file descriptor if given a non-existing file.

Daniel (24 November 2005)
- Doug Kaufman provided a set of patches to make curl build fine on DJGPP
  again using configure.

- Yang Tse provided a whole series of patches to clear up compiler warnings on
  MSVC 6.

Daniel (17 November 2005)
- I extended a patch from David Shaw to make libcurl _always_ provide an error
  string in the given error buffer to address the flaw mention on 21 sep 2005.

Daniel (16 November 2005)
- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
  installed on 'make install' time.

Daniel (14 November 2005)
- Quagmire reported that he needed to raise a NTLM buffer for SSPI to work
  properly for a case, and so we did. We raised it even for non-SSPI builds
  but it should not do any harm. https://curl.haxx.se/bug/view.cgi?id=1356715

- Jan Kunder's debian bug report
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338680 identified a weird
  error message for when you try to upload a file and the requested directory
  doesn't exist on the target server.

- Yang Tse fixed compiler warnings in lib/ssluse.c with OpenSSL 0.9.8 and in
  lib/memdebug.h that showed up in his msvc builds.

Daniel (13 November 2005)
- Debian bug report 338681 by Jan Kunder: make curl better detect and report
  bad limit-rate units:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338681 Now curl will return
  error if a bad unit is used.

- Thanks to this nice summary of poll() implementations:
  http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
  Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
  connectin closure so we check for that case (too) and re-enable poll for
  cygwin builds.

Daniel (12 November 2005)
- Eugene Kotlyarov found out that cygwin's poll() function isn't doing things
  right: https://curl.haxx.se/mail/archive-2005-11/0045.html so we now disable
  poll() and use select() on cygwin too (we already do the same choice on Mac
  OS X)

- Dima Barsky patched problem #1348930: the GnuTLS code completely ignored
  client certificates! (https://curl.haxx.se/bug/view.cgi?id=1348930).

Daniel (10 November 2005)
- David Lang fixed IPv6 support for TFTP!

- Introducing range stepping to the curl globbing support. Now you can specify
  step counter by adding :[num] within the brackets when specifying a range:

   [1-100:10]
   [a-z:2]

  If no step counter is set, it defaults to 1 as before:

   [1-100]
   [d-h]

Daniel (8 November 2005)
- Removed the use of AI_CANONNAME in the IPv6-enabled resolver functions since
  we really have no use for reverse lookups of the address.

  I truly hope these are the last reverse lookups we had lingering in the
  code!

- Dmitry Bartsevich discovered some issues in compatibilty of SSPI-enabled
  version of libcurl with different Windows versions. Current version of
  libcurl imports SSPI functions from secur32.dll. However, under Windows NT
  4.0 these functions are located in security.dll, under Windows 9x - in
  secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
  just forwards calls to secur32.dll).

  Dmitry's patch loads proper library dynamically depending on Windows
  version. Function InitSecurityInterface() is used to obtain pointers to all
  of SSPI function in one structure.

Daniel (31 October 2005)
- Vilmos Nebehaj improved libcurl's LDAP abilities:

  The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
  attributes in LDAP objects. So, I made a quick patch to address these
  problems.

  The solution is simple: if we connect to an LDAP server, first try LDAPv3
  (which is the preferred protocol as of now) and then fall back to LDAPv2.
  In case of binary attributes, we first convert them to base64, just like the
  openldap client does. It uses ldap_get_values_len() instead of
  ldap_get_values() to be able to retrieve binary attributes correctly. I
  defined the necessary LDAP macros in lib/ldap.c to be able to compile
  libcurl without the presence of libldap

Daniel (27 October 2005)
- Nis Jorgensen filed bug report #1338648
  (https://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
  feature request, but anyway. It pointed out that --max-redirs did not allow
  it to be set to 0, which then would return an error code on the first
  Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
  set to 0, or -1 for infinity. Added test case 274 to verify.

- tommink[at]post.pl reported in bug report #1337723
  (https://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
  binary data from stdin on Windows if the data contained control-Z (hex 1a)
  since that is treated as end-of-file when read in text mode. Gisle Vanem
  pointed out the fix, and I made both -T and --data-binary take advantage of
  it.

- Jaz Fresh pointed out that if you used "-r [number]" as was wrongly described
  in the man page, curl would send an invalid HTTP Range: header. The correct
  way would be to use "-r [number]-" or even "-r -[number]". Starting now,
  curl will warn if this is discovered, and automatically append a dash to the
  range before passing it to libcurl.

Daniel (25 October 2005)
- Amol Pattekar reported a bug with great detail and a fine example in bug
  #1326306 (https://curl.haxx.se/bug/view.cgi?id=1326306). When using the multi
  interface and connecting to a host with multiple IP addresses, and one of
  the addresses fails to connect (the server must exist and respond, just not
  accept connections) libcurl leaks a socket descriptor. Thanks to the fine
  report, I could find and fix this.

Daniel (22 October 2005)
- Dima Barsky reported a problem with GnuTLS-enabled libcurl in bug report
  #1334338 (https://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
  stream from a server and the server requests a "rehandshake", the current
  code simply returns this as an error. I have no good way to test this, but
  I've added a crude attempt of dealing with this situation slightly better -
  it makes a blocking handshake if this happens. Done like this because fixing
  this the "proper" way (that would handshake asynchronously) will require
  quite some work and I really need a good way to test this to do such a
  change.

Daniel (21 October 2005)
- "Ofer" reported a problem when libcurl re-used a connection and failed to do
  it, it could then accidentally actually crash. Presumably, this concerns FTP
  connections.  https://curl.haxx.se/bug/view.cgi?id=1330310

- Temprimus improved the MSVC makefile so that the static debug SSL libs are
  linked to the executable and not to the libcurld.lib
  https://curl.haxx.se/bug/view.cgi?id=1326676

- Bradford Bruce made the windows resolver code properly return
  CURLE_COULDNT_RESOLVE_PROXY and CURLE_COULDNT_RESOLVE_HOST on resolving
  errors (as documented).

Daniel (20 October 2005)
- Dave Dribin made libcurl understand and handle cases when the server
  (wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
  never happen in a sane world, libcurl previously got into an infinite loop
  when this occurred. Dave added test 273 to verify this.

- Temprimus improved the MSVC makefile: "makes a build option available so if
  you set rtlibcfg=static for the make, then it would build with /MT. The
  default behaviour is /MD (the original)."
  https://curl.haxx.se/bug/view.cgi?id=1326665

Daniel (14 October 2005)
- Reverted the LIBCURL_VERSION_NUM change from October 6. As Dave Dribin
  reported, the define is used by the configure script and is assumed to use
  the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
  release version.

Version 7.15.0 (13 October 2005)

Daniel (12 October 2005)
- Michael Sutton of iDEFENSE reported and I fixed a securitfy flaw in the NTLM
  code that would overflow a buffer if given a too long user name or domain
  name. This would happen if you enable NTLM authentication and either

  A - pass in a user name and domain name to libcurl that together are longer
      than 192 bytes

  B - allow (lib)curl to follow HTTP "redirects" (Location: and the
      appropriate HTTP 30x response code) and the new URL contains a URL with
      a user name and domain name that together are longer than 192 bytes

  See https://curl.haxx.se/docs/security.html for further details and updates

Daniel (5 October 2005)
- Darryl House reported a problem with using -z to download files from FTP.
  It turned out that if the given time stamp was exact the same as the remote
  time stamp, the file would still wrongly be downloaded. Added test case 272
  to verify.

Daniel (4 October 2005)
- Domenico Andreoli fixed a man page malformat and removed odd (0xa0) bytes
  from the configure script.

- Michael Wallner reported that the date parser had wrong offset stored for
  the MEST and CEST time zones.

Daniel (27 September 2005)
- David Yan filed bug #1299181 (https://curl.haxx.se/bug/view.cgi?id=1299181)
  that identified a silly problem with Content-Range: headers with the 'bytes'
  keyword written in a different case than all lowercase! It would cause a
  segfault!

- TJ Saunders of the proftpd project identified and pointed out problems with
  the modified FTPS negotiation change of August 19 2005. Thus, we revert the
  change back to pre-7.14.1 status.

Daniel (21 September 2005)
- Fixed "cut off" sentence in the libcurl-tutorial man page:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329305

- Clarified in the curl_easy_setopt man page what the default
  CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA mean:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329311

- Clarified in the curl_easy_setopt man page that CURLOPT_ERRORBUFFER
  sometimes doesn't fill in the buffer even though it is supposed to:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329313

- When CURLE_URL_MALFORMAT is returned due to a missing URL, it now has an
  error string set.

Daniel (19 September 2005)
- Dmitry Bartsevich made the SSPI support work on Windows 9x as well.

Daniel (15 September 2005)
- Added a TFTP server to the test suite and made the test suite capable of
  using it.

Daniel (7 September 2005)
- Ben Madsen's detailed reports that funnily enough only occurred with certain
  glibc versions turned out to be curl using an already closed file handle
  during certain conditions (like when saving FTP server "headers").

- Scott Davis helped me track down a problem in the test HTTP server that made
  test case 56 wrongly fail at times. It turned out it was due to the server
  finding the end of a chunked-encoded POST too early.

Daniel (6 September 2005)
- Now curl warns if an unknown variable is used in the -w/--writeout argument.

Daniel (4 September 2005)
- I applied Nicolas François' man page patch he posted to the Debian bug
  tracker. It corrected two lines that started with apostrophes, which isn't
  legal nroff format. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=326511

- Added --ftp-skip-pasv-ip to the command line tool, that sets the new
  CURLOPT_FTP_SKIP_PASV_IP option. It makes libcurl re-use the control
  connection's IP address when setting up the data connection instead of
  extractting the IP address from the PASV response. It has turned out this
  feature is frequently needed by people to circumvent silly servers and silly
  firewalls, especially when FTPS is used and the PASV command-response is
  sent encrtyped.

Daniel (1 September 2005)
- John Kelly added TFTP support to libcurl. A bunch of new error codes was
  added. TODO: add them to docs. add TFTP server to test suite. add TFTP to
  list of protocols whereever those are mentioned.

Version 7.14.1 (1 September 2005)

Daniel (29 August 2005)
- Kevin Lussier pointed out a problem with curllib.dsp and how to fix it.

- Igor Polyakov fixed a rather nasty problem with the threaded name resolver
  for Windows, that could lead to an Access Violation when the multi interface
  was used due to an issue with how the resolver thread was and was not
  terminated.

- Simon Josefsson brought a patch that allows curl to get built to use GNU GSS
  instead of MIT/Heimdal for GSS capabilities.

Daniel (24 August 2005)
- Toby Peterson added CURLOPT_IGNORE_CONTENT_LENGTH to the library, accessible
  from the command line tool with --ignore-content-length. This will make it
  easier to download files from Apache 1.x (and similar) servers that are
  still having problems serving files larger than 2 or 4 GB. When this option
  is enabled, curl will simply have to wait for the server to close the
  connection to signal end of transfer. I wrote test case 269 that runs a
  simple test to verify that this works.

- (Trying hard to exclude emotions now.) valgrind version 3 suddenly renamed
  the --logfile command line option to --log-file, and thus the test script
  valgrind autodetection now has yet another version check to do and then it
  alters the valgrind command line accordingly.

- Fixed CA cert verification using GnuTLS with the default bundle, which
  previously failed due to GnuTLS not allowing x509 v1 CA certs by default.
  Ralph Mitchell reported.

Daniel (19 August 2005)
- Norbert Novotny had problems with FTPS and he helped me work out a patch
  that made curl run fine in his end. The key was to make sure we do the
  SSL/TLS negotiation immediately after the TCP connect is done and not after
  a few other commands have been sent like we did previously. I don't consider
  this change necessary to obey the standards, I think this server is pickier
  than what the specs allow it to be, but I can't see how this modified
  libcurl code can add any problems to those who are interpreting the
  standards more liberally.

Daniel (17 August 2005)
- Jeff Pohlmeyer found out that if you ask libcurl to load a cookiefile (with
  CURLOPT_COOKIEFILE), add a cookie (with CURLOPT_COOKIELIST), tell it to
  write the result to a given cookie jar and then never actually call
  curl_easy_perform() - the given file(s) to read was never read but the
  output file was written and thus it caused a "funny" result.

- While doing some tests for the bug above, I noticed that Firefox generates
  large numbers (for the expire time) in the cookies.txt file and libcurl
  didn't treat them properly. Now it does.

Daniel (15 August 2005)
- Added more verbose "warning" messages to the curl client for cases where it
  fails to open/read files etc to help users diagnose why it doesn't do what
  you'd expect it to. Converted lots of old messages to use the new generic
  function I wrote for this purpose.

Daniel (13 August 2005)
- James Bursa identified a libcurl HTTP bug and a good way to repeat it. If a
  site responds with bad HTTP response that doesn't contain any header at all,
  only a response body, and the write callback returns 0 to abort the
  transfer, it didn't have any real effect but the write callback would be
  called once more anyway.

Daniel (12 August 2005)
- Based on Richard Clayton's reports, I found out that using curl -d @filename
  when 'filename' was not possible to access made curl use a GET request
  instead.

- The time condition illegal syntax warning is now inhibited if -s is used.

Daniel (10 August 2005)
- Mario Schroeder found out that one of the debug callbacks calls that regards
  SSL data with the CURLINFO_TEXT type claimed that the data was one byte
  larger than it actually is, thus falsely telling the application that the
  terminating zero was part of the data.

Daniel (9 August 2005)
- Christopher R. Palmer fixed the offsets used for date parsings when the time
  zone name of a daylight savings time was used. For example, PDT vs PDS. This
  flaw was introduced with the new date parser (11 sep 2004 - 7.12.2).
  Fortunately, no web server or cookie string etc should be using such time
  zone names thus limiting the effect of this bug.

Daniel (8 August 2005)
- Jon Grubbs filed bug report #1249962
  (https://curl.haxx.se/bug/view.cgi?id=1249962) which identified a problem
  with NTLM on a HTTP proxy if an FTP URL was given. libcurl now properly
  switches to pure HTTP internally when an HTTP proxy is used, even for FTP
  URLs. The problem would also occur with other multi-pass auth methods.

Daniel (7 August 2005)
- When curl is built with GnuTLS, curl-config didn't include "SSL" when
  --features was used.

Daniel (28 July 2005)
- If any of the options CURLOPT_HTTPGET, CURLOPT_POST and CURLOPT_HTTPPOST is
  set to 1, CURLOPT_NOBODY will now automatically be set to 0.

Daniel (27 July 2005)
- Dan Fandrich changes over the last week: fixed numerous minor configure
  option parsing flaws: --without-gnutls, --without-spnego --without-gssapi
  and --without-krb4. Spellfixed several error messages.

- Peteris Krumins added CURLOPT_COOKIELIST and CURLINFO_COOKIELIST, which is a
  simple interface to extracting and setting cookies in libcurl's internal
  "cookie jar". See the new cookie_interface.c example code.

Daniel (13 July 2005)
- Diego Casorran provided patches to make curl build fine on Amiga again.

Daniel (12 July 2005)
- Adrian Schuur added trailer support in the chunked encoding stream. The
  trailer is then sent to the normal header callback/stream. I wrote up test
  case 266 to verify the basic functionality. Do note that test case 34
  contains a flawed chunked encoding stream that still works the same.

Daniel (5 July 2005)
- Gisle Vanem came up with a nice little work-around for bug #1230118
  (https://curl.haxx.se/bug/view.cgi?id=1230118). It seems the Windows (MSVC)
  libc time functions may return data one hour off if TZ is not set and
  automatic DST adjustment is enabled. This made curl_getdate() return wrong
  value, and it also concerned internal cookie expirations etc.

Daniel (4 July 2005)
- Andrew Bushnell provided enough info for me to tell that we badly needed to
  fix the CONNECT authentication code with multi-pass auth methods (such as
  NTLM) as it didn't previously properly ignore response-bodies - in fact it
  stopped reading after all response headers had been received. This could
  lead to libcurl sending the next request and reading the body from the first
  request as response to the second request. (I also renamed the function,
  which wasn't strictly necessary but...)

  The best fix would to once and for all make the CONNECT code use the
  ordinary request sending/receiving code, treating it as any ordinary request
  instead of the special-purpose function we have now. It should make it
  better for multi-interface too. And possibly lead to less code...

  Added test case 265 for this. It doesn't work as a _really_ good test case
  since the test proxy is too stupid, but the test case helps when running the
  debugger to verify.

Daniel (30 June 2005)
- Dan Fandrich improved the configure script's ability to figure out what kind
  of strerror_r() API that is used when cross-compiling. If __GLIB__ is
  defined, it assumes the glibc API. If not, it issues a notice as before that
  the user needs to manually edit lib/config.h for this.

Daniel (23 June 2005)
- David Shaw's fix that unifies proxy string treatment so that a proxy given
  with CURLOPT_PROXY can use a http:// prefix and user + password. The user
  and password fields are now also URL decoded properly. Test case 264 added
  to verify.

Daniel (22 June 2005)
- David Shaw updated libcurl.m4

Daniel (14 June 2005)
- Gisle Vanem fixed a potential thread handle leak. Bug report #1216500
  (https://curl.haxx.se/bug/view.cgi?id=1216500).  Comment in
  https://curl.haxx.se/mail/lib-2005-06/0059.html

Daniel (13 June 2005)
- Made buildconf run libtoolize in the ares dir too (inspired by Tupone's
  reverted patch).

Daniel (9 June 2005)
- Incorporated Tupone's findtool fix in buildconf (slightly edited)

- Incorporated Tupone's head -n fix in buildconf.

Daniel (8 June 2005)
- Reverted Tupone's patch again, it broke numerous autobuilds. Let's apply it
  in pieces, one by one and see what we need to adjust to work all over.

Daniel (6 June 2005)
- Tupone Alfredo fixed three problems in buildconf:

  1) findtool does look per tool in PATH and think ./perl is the perl
  executable, while is just a local directory (I have . in the PATH)

  2) I got several warning for head -1 deprecated in favour of head -n 1

  3) ares directory is missing some file (missing is missing :-) ) because
  automake and friends is not run.

Daniel (3 June 2005)
- Added docs/libcurl/getinfo-times, based on feedback from 'Edi':
  https://curl.haxx.se/feedback/display.cgi?id=11178325798299&support=yes

- Andres Garcia provided yet another text mode patch for several test cases so
  that they do text comparisions better on Windows (newline-wise).

Daniel (1 June 2005)
- The configure check for c-ares now adds the cares lib before the other libs,
  to make it build fine with mingw. Inspired by Tupone Alfredo's bug report
  and patch: https://curl.haxx.se/bug/view.cgi?id=1212940

Daniel (31 May 2005)
- Todd Kulesza reported a flaw in the proxy option, since a numerical IPv6
  address was not possible to use. It is now, but requires it written
  RFC2732-style, within brackets - which incidently is how you enter numerical
  IPv6 addresses in URLs. Test case 263 added to verify.

Daniel (30 May 2005)
- Eric Cooper reported about a problem with HTTP servers that responds with
  binary zeroes within the headers. They confused libcurl to do wrong so the
  downloaded headers become incomplete. The fix is now verified with test case
  262. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=310948

Daniel (25 May 2005)
- Fixed problems with the test suite, and in particular the FTP test cases
  since it previously was failing every now and then in a nonsense manner.

- --trace-time now outputs the full microsecond, all 6 digits.

Daniel (24 May 2005)
- Andres Garcia provided a text mode patch for several test cases so that they
  do text comparisions better on Windows (newline-wise).

- Any 2xx response (and not just 200) is now considered a fine response to
  TYPE, as some servers obviously sends a 226 there. Added test case 261 to
  verify. Based on a question/report by Georg Wicherski.

Daniel (20 May 2005)
- Improved runtests.pl to allow stdout tests to be mode=text as well, just
  as file comparisons already supports. Added this info to the FILEFORMAT
  docs.

Daniel (18 May 2005)
- John McGowan identified a problem in bug report #1204435
  (https://curl.haxx.se/bug/view.cgi?id=1204435) with malformed URLs like
  "http://somehost?data" as it added a slash too much in the request ("GET
  /?data/"...). Added test case 260 to verify.

- The configure check for strerror_r() failed to detect the proper API at
  times, like on HP-UX 10.20. Then lib/strerror.c badly assumed the glibc
  version if the posix define wasn't set (since it _had_ found a strerror_r).

Daniel (16 May 2005)
- The gmtime_r() function in HP-UX 10.20 is broken. About 13 test cases fail
  due to this. There's now a configure check that attempts to detect the bad
  function and not use it on such systems.

Version 7.14.0 (16 May 2005)

Daniel (13 May 2005)
- Grigory Entin reported that curl's configure detects a fine poll() for Mac
  OS X 10.4 (while 10.3 or later detected a "bad" one), but the executable
  doesn't work as good as if built without poll(). I've adjusted the configure
  to always skip the fine-poll() test on Mac OS X (darwin).

Daniel (12 May 2005)
- When doing a second request (after a disconnect) using the same easy handle,
  over a proxy that uses NTLM authentication, libcurl failed to use NTLM again
  properly (the auth method was accidentally reset to the same as had been set
  for host auth, which defaults to Basic). Bug report #1200661
  (https://curl.haxx.se/bug/view.cgi?id=1200661) identified the the problem and
  the fix.

- If -z/--time-cond is used with an invalid date syntax, this is no longer
  silently discarded. Instead a proper warning message is diplayed that
  informs about it. But it still continues without the condition.

Version 7.14.0-pre2 (11 May 2005)

Daniel (11 May 2005)
- Starting now, libcurl sends a little different set of headers in its default
  HTTP requests:

  A) Normal non-proxy HTTP:
    - no more "Pragma: no-cache" (this only makes sense to proxies)

  B) Non-CONNECT HTTP request over proxy:
    - "Pragma: no-cache" is used (like before)
    - "Proxy-Connection: Keep-alive" (for older style 1.0-proxies)

  C) CONNECT HTTP request over proxy:
    - "Host: [name]:[port]"
    - "Proxy-Connection: Keep-alive"

  The A) case is mostly to reduce the default header size and remove a
  pointless header.

  The B) is to address (rare) problems with HTTP 1.0 proxies

  The C) headers are both to address (rare) problems with some proxies. The
  code in libcurl that deals with CONNECT requests need a rewrite, but it
  feels like a too big a job for me to do now. Details are added in the code
  comments for now.

  Updated a large amount of test cases to reflect the news.

Daniel (10 May 2005)
- Half-baked attempt to bail out if select() returns _only_ errorfds when the
  transfer is in progress. An attempt to fix Allan's problem. See
  https://curl.haxx.se/mail/lib-2005-05/0073.html and the rest of that thread
  for details.

  I'm still not sure this is the right fix, but...

Version 7.14.0-pre1 (9 May 2005)

Daniel (2 May 2005)
- Sort of "fixed" KNOWN_BUGS #4: curl now builds IPv6 enabled on AIX 4.3. At
  least it should no longer cause a compiler error. However, it does not have
  AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it
  (we use that for FTP PORT/EPRT)! So, I modified the configure check that
  checks if the getaddrinfo() is working, to use AI_NUMERICHOST since then
  it'll fail on AIX 4.3 and it will automatically build with IPv6 support
  disabled.

- Added --trace-time that when used adds a time stamp to each trace line that
  --trace, --trace-ascii and --verbose output. I also made the '>' display
  separate each line on the linefeed so that HTTP requests etc look nicer in
  the -v output.

- Made curl recognize the environment variables Lynx (and others?) support for
  pointing out the CA cert path/file: SSL_CERT_DIR and SSL_CERT_FILE. If
  CURL_CA_BUNDLE is not set, they are checked afterwards.

  Like before: on windows if none of these are set, it checks for the ca cert
  file like this:

  1. application's directory
  2. current working directory
  3. Windows System directory (e.g. C:\windows\system32)
  4. Windows Directory (e.g. C:\windows)
  5. all directories along %PATH%

Daniel (1 May 2005)
- The runtests.pl script now starts test servers by doing fork() and exec()
  instead of the previous approach. This is less complicated and should
  hopefully lead to less "leaked" servers (servers that aren't stopped
  properly when the tests are stopped).

- Alexander Zhuravlev found a case when you did "curl -I [URL]" and it
  complained on the chunked encoding, even though a HEAD should never return a
  body and thus it cannot be a chunked-encoding problem!

Daniel (30 April 2005)
- Alexander Zhuravlev found out that (lib)curl SIGSEGVed when using
  --interface on an address that can't be bound.

Daniel (28 April 2005)
- Working on fixing up test cases to mark sections as 'mode=text' for things
  that curl writes as text files, since then they can get different line
  endings depending on OS. Andrés García helps me work this out.

  Did lots of other minor tweaks on the test scripts to work better and more
  reliably find test servers and also kill test servers.

- Dan Fandrich pointed out how the runtests.pl script killed the HTTP server
  instead of the HTTPS server when closing it down.

Daniel (27 April 2005)
- Paul Moore made curl check for the .curlrc file (_curlrc on windows) on two
  more places. First, CURL_HOME is a new environment variable that is used
  instead of HOME if it is set, to point out where the default config file
  lives. If there's no config file in the dir pointed out by one of the
  environment variables, the Windows version will instead check the same
  directory the executable curl is located in.

Daniel (26 April 2005)
- Cory Nelson's work on nuking compiler warnings when building on x64 with
  VS2005.

Daniel (25 April 2005)
- Fred New reported a bug where we used Basic auth and user name and password
  in .netrc, and when following a Location: the subsequent requests didn't
  properly use the auth as found in the netrc file. Added test case 257 to
  verify my fix.

- Based on feedback from Cory Nelson, I added some preprocessor magic in
  */setup.h and */config-win32.h to build fine with VS2005 on x64.

Daniel (23 April 2005)
- Alex Suykov made the curl tool now assume that uploads using HTTP:// or
  HTTPS:// are the only ones that show output and thus motivates a switched
  off progress meter if the output is sent to the terminal. This makes FTP
  uploads without '>', -o or -O show the progress meter.

Daniel (22 April 2005)
- Dave Dribin's MSVC makefile fix: set CURL_STATICLIB when it builds static
  library variants.

- Andres Garcia fixed configure to set the proper define when building static
  libcurl on windows.

- --retry-delay didn't work.

Daniel (18 April 2005)
- Olivier reported that even though he used CURLOPT_PORT, libcurl clearly
  still used the default port. He was right. I fixed the problem and added the
  test cases 521, 522 and 523 to verify the fix.

- Toshiyuki Maezawa reported that when doing a POST with a read callback,
  libcurl didn't properly send an Expect: 100-continue header. It does now.

- I committed by mig change in the test suite's FTP server that moves out all
  socket/TCP code to a separate C program named sockfilt. And added 4 new
  test cases for FTP over IPv6.

Daniel (8 April 2005)
- Cory Nelson reported a problem with a HTTP server that responded with a 304
  response containing an "illegal" Content-Length: header, which was not
  properly ignored by libcurl. Now it is. Test case 249 verifies.

Daniel (7 April 2005)
- Added ability to build and run with GnuTLS as an alternative to OpenSSL for
  the secure layer. configure --with-gnutls enables with. Note that the
  previous OpenSSL check still has preference and if it first detects OpenSSL,
  it will not check for GnuTLS. You may need to explictly diable OpenSSL with
  --without-ssl.

  This work has been sponsored by The Written Word.

Daniel (5 April 2005)
- Christophe Legry fixed the post-upload check for FTP to not complain if the
  upload was skipped due to a time-condition as set with
  CURLOPT_TIMECONDITION. I added test case 247 and 248 to verify.

Version 7.13.2 (5 April 2005)

Daniel (4 April 2005)
- Marcelo Juchem fixed the MSVC makefile for libcurl

- Gisle Vanem fixed a crash in libcurl, that could happen if the easy handle
  was killed before the threading resolver (windows only) still hadn't
  completed.

- Hardeep Singh reported a problem doing HTTP POST with Digest. (It was
  actually also affecting NTLM and Negotiate.) It turned out that if the
  server responded with 100 Continue before the initial 401 response, libcurl
  didn't take care of the response properly. Test case 245 and 246 added to
  verify this.

Daniel (30 March 2005)
- Andres Garcia modified the configure script to check for libgdi32 before
  libcrypto, to make the SSL check work fine on msys/mingw.

Daniel (29 March 2005)
- Tom Moers identified a flaw when you sent a POST with Digest authentication,
  as in the first request when curl sends a POST with Content-Length: 0, it
  still forcibly closed the connection before doing the next step in the auth
  negotiation.

- Jesper Jensen found out that FTP-SSL didn't work since my FTP
  rewrite. Fixing that was easy, but it also revealed a much worse problem:
  the FTP server response reader function didn't properly deal with reading
  responses in multiple tiny chunks properly! I modified the FTP server to
  allow it to produce such split-up responses to make sure curl deals with
  them as it should.

- Based on Augustus Saunders' comments and findings, the HTTP output auth
  function was fixed to use the proper proxy authentication when multiple ones
  are accepted. test 239 and test 243 were added to repeat the problems and
  verify the fixes.

  --proxy-anyauth was added to the curl tool

Daniel (16 March 2005)
- Tru64 and some IRIX boxes seem to not like test 237 as it is. Their
  inet_addr() functions seems to use &255 on all numericals in a ipv4 dotted
  address which makes a different failure... Now I've modified the IPv4
  resolve code to use inet_pton() instead in an attempt to make these systems
  better detect this as a bad IP address rather than creating a toally bogus
  address that is then passed on and used.

Daniel (15 March 2005)
- Dan Fandrich made the code properly use the uClibc's version of
  inet_ntoa_r() when built with it.

- Added test 237 and 238: test EPSV and PASV response handling when they get
  well- formated data back but using illegal values. In 237 PASV gets an IP
  address that is way bad. In 238 EPSV gets a port that is way out of range.

Daniel (14 March 2005)
- Added a few missing features to the curl-config --features list

- Modified testcurl.pl to now offer
  1 - command line options for all info it previously only read from
      file: --name, --email, --desc and --configure
  2 - --nocvsup makes it not attempt to do cvs update
  3 - --crosscompile informs it and makes it not attempt things it can't do

- Fixed numerous win32 compiler warnings.

- Removed the lib/security.h file since it shadowed the mingw/win32 header
  with the same name which is needed for SSPI builds. The contents of the
  former security.h is now i krb4.h

- configure --enable-sspi now enables SSPI in the build. It only works for
  windows builds (including cross-compiles for windows).

Daniel (12 March 2005)
- David Houlder added --form-string that adds that string to a multipart
  formpost part, without special characters having special meanings etc like
  --form features.

Daniel (11 March 2005)
- curl_version_info() returns the feature bit CURL_VERSION_SSPI if it was
  built with SSPI support.

- Christopher R. Palmer made it possible to build libcurl with the
  USE_WINDOWS_SSPI on Windows, and then libcurl will be built to use the
  native way to do NTLM. SSPI also allows libcurl to pass on the current user
  and its password in the request.

Daniel (9 March 2005)
- Dan F improved the SSL lib setup in configure.

- Nodak Sodak reported a crash when using a SOCKS4 proxy.

- Jean-Marc Ranger pointed out an embarassing debug printf() leftover in the
  multi interface code.

- Adjusted the man page for the curl_getdate() return value for dates after
  year 2038. For 32 bit time_t it returns 0x7fffffff but for 64bit time_t it
  returns either the correct value or even -1 on some systems that still seem
  to not deal with this properly. Tor Arntsen found a 64bit AIX system for us
  that did the latter. Gwenole Beauchesne's Mandrake patch put the lights on
  this problem in the first place.

Daniel (8 March 2005)
- Dominick Meglio reported that using CURLOPT_FILETIME when transferring a FTP
  file got a Last-Modified: header written to the data stream, corrupting the
  actual data. This was because some conditions from the previous FTP code was
  not properly brought into the new FTP code. I fixed and I added test case
  520 to verify. (This bug was introduced in 7.13.1)

- Dan Fandrich fixed the configure --with-zlib option to always consider the
  given path before any standard paths.

Daniel (6 March 2005)
- Randy McMurchy was the first to report that valgrind.pm was missing from the
  release archive and thus 'make test' fails.

Daniel (5 March 2005)
- Dan Fandrich added HAVE_FTRUNCATE to several config-*.h files.

- Added test case 235 that makes a resumed upload of a file that isn't present
  on the remote side. This then converts the operation to an ordinary STOR
  upload. This was requested/pointed out by Ignacio Vazquez-Abrams.

  It also proved (and I fixed) a bug in the newly rewritten ftp code (and
  present in the 7.13.1 release) when trying to resume an upload and the
  servers returns an error to the SIZE command. libcurl then loops and sends
  SIZE commands infinitely.

- Dan Fandrich fixed a SSL problem introduced on February 9th that made
  libcurl attempt to load the whole random file to seed the PRNG. This is
  really bad since this turns out to be using /dev/urandom at times...

Version 7.13.1 (4 March 2005)

Daniel (4 March 2005)
- Dave Dribin made it possible to set CURLOPT_COOKIEFILE to "" to activate
  the cookie "engine" without having to provide an empty or non-existing file.

- Rene Rebe fixed a -# crash when more data than expected was retrieved.

Daniel (22 February 2005)
- NTLM and ftp-krb4 buffer overflow fixed, as reported here:
  http://www.securityfocus.com/archive/1/391042 and the CAN report here:
  https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0490

  If these security guys were serious, we'd been notified in advance and we
  could've saved a few of you a little surprise, but now we weren't.

Daniel (19 February 2005)
- Ralph Mitchell reported a flaw when you used a proxy with auth, and you
  requested data from a host and then followed a redirect to another
  host. libcurl then didn't use the proxy-auth properly in the second request,
  due to the host-only check for original host name wrongly being extended to
  the proxy auth as well. Added test case 233 to verify the flaw and that the
  fix removed the problem.

Daniel (18 February 2005)
- Mike Dobbs reported a mingw build failure due to the lack of
  BUILDING_LIBCURL being defined when libcurl is built. Now this is defined by
  configure when mingw is used.

Daniel (17 February 2005)
- David in bug report #1124588 found and fixed a socket leak when libcurl
  didn't close the socket properly when returning error due to failing
  localbind

Daniel (16 February 2005)
- Christopher R. Palmer reported a problem with HTTP-POSTing using "anyauth"
  that picks NTLM. Thanks to David Byron letting me test NTLM against his
  servers, I could quickly repeat and fix the problem. It turned out to be:

  When libcurl POSTs without knowing/using an authentication and it gets back
  a list of types from which it picks NTLM, it needs to either continue
  sending its data if it keeps the connection alive, or not send the data but
  close the connection. Then do the first step in the NTLM auth. libcurl
  didn't send the data nor close the connection but simply read the
  response-body and then sent the first negotiation step. Which then failed
  miserably of course. The fixed version forces a connection if there is more
  than 2000 bytes left to send.

Daniel (14 February 2005)
- The configure script didn't check for ENGINE_load_builtin_engines() so it
  was never used.

Daniel (11 February 2005)
- Removed all uses of strftime() since it uses the localised version of the
  week day names and month names and servers don't like that.

Daniel (10 February 2005)
- Now the test script disables valgrind-testing when the test suite runs if
  libcurl is built shared. Otherwise valgrind only tests the shell that runs
  the wrapper-script named 'curl' that is a front-end to curl in this case.
  This should also fix the huge amount of reports of false positives when
  valgrind has identified leaks in (ba)sh and not in curl and people report
  that as curl bugs. Bug report #1116672 is one example.

  Also, the valgrind report parser has been adapted to check that at least one
  of the sources in a stack strace is one of (lib)curl's source files or
  otherwise it will not consider the problem to concern (lib)curl.

- Marty Kuhrt streamlined the VMS build.

Daniel (9 February 2005)
- David Byron fixed his SSL problems, initially mentioned here:
  https://curl.haxx.se/mail/lib-2005-01/0240.html. It turned out we didn't use
  SSL_pending() as we should.

- Converted lots of FTP code to a statemachine, so that the multi interface
  doesn't block while communicating commands-responses with an FTP server.

  I've added a comment like BLOCKING in the code on all spots I could find
  where we still have blocking operations. When we change curl_easy_perform()
  to use the multi interface, we'll also be able to simplify the code since
  there will only be one "internal interface".

  While doing this, I've now made CURLE_FTP_ACCESS_DENIED separate from the
  new CURLE_LOGIN_DENIED. The first one is now access denied to a function,
  like changing directory or retrieving a file, while the second means that we
  were denied login.

  The CVS tag 'before_ftp_statemachine' was set just before this went in, in
  case of future need.

- Gisle made the DICT code send CRLF and not just LF as the spec says so.

Daniel (8 February 2005)
- Gisle fixed problems when libcurl runs out of memory, and worked on making
  sure the proper error code is returned for those occations.

Daniel (7 February 2005)
- Maruko pointed out a problem with inflate decompressing exactly 64K
  contents.

Daniel (5 February 2005)
- Eric Vergnaud found a use of an uninitialised variable in the ftp when doing
  PORT on IPv6-enabled hosts.

- David Byron pointed out we could use BUFSIZE to read data (in
  lib/transfer.c) instead of using BUFSIZE -1.

Version 7.13.0 (1 February 2005)

Daniel (31 January 2005)
- Added Lars Nilsson's htmltitle.cc example

Daniel (30 January 2005)
- Fixed a memory leak when using the multi interface and the DO operation
  failed (as in test case 205).

- Fixed a valgrind warning for file:// operations.

- Fixed a valgrind report in the url globbing code for the curl command line
  tool.

- Bugfixed the parser that scans the valgrind report outputs (in runtests.pl).
  I noticed that it previously didn't detect and report the "Conditional jump
  or move depends on uninitialised value(s)" error. When I fixed this, I
  caught a few curl bugs with it. And then I had to spend time to make the
  test suite IGNORE these errors when OpenSSL is used since it produce massive
  amounts of valgrind warnings (but only of the "Conditional..." kind it
  seems). So, if a test that requires SSL is run, it ignores the
  "Conditional..." errors, and you'll get a "valgrind PARTIAL" output instead
  of "valgrind OK".

Daniel (29 January 2005)
- Using the multi interface, and doing a requsted a re-used connection that
  gets closed just after the request has been sent failed and did not re-issue
  a request on a fresh reconnect like the easy interface did. Now it does!

- Define CURL_MULTIEASY when building libcurl (lib/easy.c to be exact), to use
  my new curl_easy_perform() that uses the multi interface to run the
  request. It is a great testbed for the multi interface and I believe we
  shall do it this way for real in the future when we have a successor to
  curl_multi_fdset(). I've used this approach to detect and fix several of the
  recent multi-interfaces issues.

- Adjusted the KNOWN_BUGS #17 fix a bit more since the FTP code also did some
  bad assumptions.

- multi interface: when a request is denied due to "Maximum redirects
  followed" libcurl leaked the last Location: URL.

- Connect failures with the multi interface was often returned as "connect()
  timed out" even though the reason was different.

Daniel (28 January 2005)
- KNOWN_BUGS #17 fixed. A DNS cache entry may not remain locked between two
  curl_easy_perform() invokes. It was previously unlocked at disconnect, which
  could mean that it remained locked between multiple transfers. The DNS cache
  may not live as long as the connection cache does, as they are separate.

  To deal with the lack of DNS (host address) data availability in re-used
  connections, libcurl now keeps a copy of the IP adress as a string, to be
  able to show it even on subsequent requests on the same connection.

  The problem could be made to appear with this stunt:

  1. create a multi handle
  2. add an easy handle
  3. fetch a URL that is persistent (leaves the connection alive)
  4. remove the easy handle from the multi
  5. kill the multi handle
  6. create a multi handle
  7. add the same easy handle to the new multi handle
  8. fetch a URL from the same server as before (re-using the connection)

- Stephen More pointed out that CURLOPT_FTPPORT and the -P option didn't work
  when built IPv6-enabled. I've now made a fix for it. Writing test cases for
  custom port hosts turned too tricky so unfortunately there's none.

Daniel (25 January 2005)
- Ian Ford asked about support for the FTP command ACCT, and I discovered it
  is present in RFC959... so now (lib)curl supports it as well. --ftp-account
  and CURLOPT_FTP_ACCOUNT set the account string. (The server may ask for an
  account string after PASS have been sent away. The client responds
  with "ACCT [account string]".) Added test case 228 and 229 to verify the
  functionality. Updated the test FTP server to support ACCT somewhat.

- David Shaw contributed a fairly complete and detailed autoconf test you can
  use to detect libcurl and setup variables for the protocols the installed
  libcurl supports: docs/libcurl/libcurl.m4

Daniel (21 January 2005)
- Major FTP third party transfer overhaul.

  These four options are now obsolete: CURLOPT_SOURCE_HOST,
  CURLOPT_SOURCE_PATH, CURLOPT_SOURCE_PORT (this option didn't work before)
  and CURLOPT_PASV_HOST.

  These two options are added: CURLOPT_SOURCE_URL and CURLOPT_SOURCE_QUOTE.

  The target-side didn't use the proper path with RETR, and thus this only
  worked correctly in the login path (i.e without doing any CWD). The source-
  side still uses a wrong path, but the fix for this will need to wait. Verify
  the flaw by using a source URL with included %XX-codes.

  Made CURLOPT_FTPPORT control weather the target operation should use PORT
  (or not). The other side thus uses passive (PASV) mode.

  Updated the ftp3rdparty.c example source to use the updated options.

  Added support for a second FTP server in the test suite. Named... ftp2.
  Added test cases 230, 231 and 232 as a few first basic tests of very simple
  3rd party transfers.

  Changed the debug output to include 'target' and 'source' when a 3rd party
  is being made, to make it clearer what commands/responses came on what
  connection.

  Added three new command line options: --3p-url, --3p-user and --3p-quote.

  Documented the command line options and the curl_easy_setopt options related
  to third party transfers.

  (Temporarily) disabled the ability to re-use an existing connection for the
  source connection. This is because it needs to force a new in case the
  source and target is the same host, and the host name check is trickier now
  when the source is identified with a full URL instead of a plain host name
  like before.

  TODO (short-term) for 3rd party transfers: quote support. The options are
  there, we need to add test cases to verify their functionality.

  TODO (long-term) for 3rd party transfers: IPv6 support (EPRT and EPSV etc)
  and SSL/TSL support.

Daniel (20 January 2005)
- Philippe Hameau found out that -Q "+[command]" didn't work, although some
  code was written for it. I fixed and added test case 227 to verify it.
  The curl.1 man page didn't mention the '+' so I added it.

Daniel (19 January 2005)
- Stephan Bergmann made libcurl return CURLE_URL_MALFORMAT if an FTP URL
  contains %0a or %0d in the user, password or CWD parts. (A future fix would
  include doing it for %00 as well - see KNOWN_BUGS for details.) Test case
  225 and 226 were added to verify this

- Stephan Bergmann pointed out two flaws in libcurl built with HTTP disabled:

  1) the proxy environment variables are still read and used to set HTTP proxy

  2) you couldn't disable http proxy with CURLOPT_PROXY (since the option was
     disabled). This is important since apps may want to disable HTTP proxy
     without actually knowing if libcurl was built to disable HTTP or not.

  Based on Stephan's patch, both these issues should now be fixed.

Daniel (18 January 2005)
- Cody Jones' enhanced version of Samuel Díaz García's MSVC makefile patch was
  applied.

Daniel (16 January 2005)
- Alex aka WindEagle pointed out that when doing "curl -v dictionary.com", curl
  assumed this used the DICT protocol. While guessing protocols will remain
  fuzzy, I've now made sure that the host names must start with "[protocol]."
  for them to be a valid guessable name. I also removed "https" as a prefix
  that indicates HTTPS, since we hardly ever see any host names using that.

Daniel (13 January 2005)
- Inspired by Martijn Koster's patch and example source at
  http://www.greenhills.co.uk/mak/gentoo/curl-eintr-bug.c, I now made the
  select() and poll() calls properly loop if they return -1 and errno is
  EINTR. glibc docs for this is found here:
  https://www.gnu.org/software/libc/manual/html_node/Interrupted-Primitives.html

  This last link says BSD doesn't have this "effect". Will there be a problem
  if we do this unconditionally?

Daniel (11 January 2005)
- Dan Torop cleaned up a few no longer used variables from David Phillips'
  select() overhaul fix.

- Cyrill Osterwalder posted a detailed analysis about a bug that occurs when
  using a custom Host: header and curl fails to send a request on a re-used
  persistent connection and thus creates a new connection and resends it. It
  then sent two Host: headers. Cyrill's analysis was posted here:
  https://curl.haxx.se/mail/archive-2005-01/0022.html

- Bruce Mitchener identified (bug report #1099640) the never-ending SOCKS5
  problem with the version byte and the check for bad versions. Bruce has lots
  of clues on this, and based on his suggestion I've now removed the check of
  that byte since it seems to be able to contain 1 or 5.

Daniel (10 January 2005)
- Pavel Orehov reported memory problems with the multi interface in bug report
  #1098843. In short, a shared DNS cache was setup for a multi handle and when
  the shared cache was deleted before the individual easy handles, the latter
  cleanups caused read/writes to already freed memory.

- Hzhijun reported a memory leak in the SSL certificate code, that leaked the
  remote certificate name when it didn't match the used host name.

Gisle (8 January 2005)
- Added Makefile.Watcom files (src/lib). Updated Makefile.dist.

Daniel (7 January 2005)
- Improved the test script's valgrind log parser to actually work! Also added
  the ability to disable the log scanner for specific test cases. Test case
  509 results in numerous problems and leaks in OpenSSL and has to get it
  disabled.

Daniel (6 January 2005)
- Fixed a single-byte read out of bounds in test case 39 in the curl tool code
  (i.e not in the library).

- Bug report #1097019 identified a problem when doing -d "data" with -G and
  sending it to two URLs with {}. Added test 199 to verify the fix.

Daniel (4 January 2005)
- Marty Kuhrt adjusted a VMS build script slightly

- Kai Sommerfeld and Gisle Vanem fixed libcurl to build with IPv6 support on
  Win2000.

Daniel (2 January 2005)
- Alex Neblett updated the MSVC makefiles slightly.
Daniel (25 December 2004)
- Removed src/config.h.in from CVS, it is now copied from the (generated)
  lib/config.h.in instead, as they can very well be the same. This removes a
  "manual hassle". You may want to re-run buildconf now.

- Werner Koch filed Debian bug report #286794, mentioning that curl contained
  non-free (by Debian's view) source code. This was Angus Mackay's
  src/getpass.c source code. I tried to contact him about it to quickly solve
  this issue, but his email addresses bounce and I got some time "over" and
  reimplemented the functionality once brought by Angus. We no longer use any
  of Angus' original code and the new function is much simpler (IMO). Issue
  solved.

Daniel (24 December 2004)
- David Shaw added --protocols to curl-config, so that it now lists all
  protocols libcurl was built to support. --feature no longer lists disabled
  protocols.

Daniel (23 December 2004)
- David Shaw fixed the configure --disable-[protocol] variables so that
  curl-config --feature now works correctly!

Daniel (22 December 2004)
- Rune Kleveland fixed a minor memory leak for received cookies with the
  (rare) version attribute set.

- Marcin Konicki provided two configure fixes and a source fix to make curl
  build out-of-the-box on BeOS.

Daniel (21 December 2004)
- Added test case 217 that verified CURLINFO_HTTP_CONNECTCODE, and I made the
  -w option support 'http_connect' to make it easier to verify!

- Fixed lib/select.c include order to build fine on FreeBSD

- Fixed failf()'s reuse of the va_list variable that crashed on FreeBSD.
  Pointed out by Peter Pentchev.

Version 7.12.3 (20 December 2004)

Daniel (19 December 2004)
- I investigated our PKCS12 build problem on Solaris 2.7 with OpenSSL 0.9.7e,
  and it turned out to be the fault of the zlib 1.1.4 headers doing a typedef
  named 'free_func' and the OpenSSL headers have a prototype that uses
  'free_func' in one of its arguments. This is why the compile errors out.

  In other words, we need to include the openssl/pkcs12.h header before the
  zlib.h header and it builds fine. The configure script now checks for this
  file and it then gets included early in lib/urldata.h.

Daniel (18 December 2004)
- Samuel Listopad added support for PKCS12 formatted certificates.

- Samuel Listopad fixed -E to support "C:/path" (with forward slash) as well.

Daniel (16 December 2004)
- Gisle found and fixed a problem in the directory re-use for FTP.

  I added test case 215 and 216 to better verify the functionality.

- Dinar in bug report #1086121, found a file handle leak when a multipart
  formpost (including a file upload part) was aborted before the whole file
  was sent.

Daniel (15 December 2004)
- Tom Lee found out that globbing of strings with backslashes didn't work as
  you'd expect. Backslashes are such a central part of windows file names that
  forcing backslashes to have to be escaped with backslashes is a bit too
  awkward to users. Starting now, you only need to escape globbing characters
  such as the five letters: "[]{},". Added test case 214 to verify this.

Daniel (14 December 2004)
- Harshal Pradhan patched a HTTP persistent connection flaw: if the user name
  and/or password were modified between two requests on a persistent
  connection, the second request were still made with the first setup!

  I added test case 519 to verify the fix.

Daniel (13 December 2004)
- Gisle added CURLINFO_SSL_ENGINES to curl_easy_getinfo() to allow an app
  to list all available crypto ENGINES.

- Gisle fixed bug report #1083542, which pointed out a problem with resuming
  large file (>4GB) file:// transfers on windows.

Daniel (11 December 2004)
- Made the test suite HTTP server (sws) capable of using IPv6, and then
  extended the test environment to support that and also added three test
  cases (240, 241, 242) that run tests using IPv6. Test 242 uses a URL that
  didn't work before the 10 dec fix by Kai Sommerfeld.

- Made a failed file:// resume output an error message

- Corrected the CURLE_BAD_DOWNLOAD_RESUME error message in lib/strerror.c

- Dan Fandrich:

  simplified and consolidated the SSL checks in configure and the usage of the
  defines in lib/setup.h

  provided a first libcurl.pc.in file for pkg-config (but the result is not
  installed anywhere at this point)

  extended the cross compile section in the docs/INSTALL file

Daniel (10 December 2004)
- When providing user name in the URL and a IPv6-style IP-address (like in
  "ftp://user@[::1]/tmp"), the URL parser didn't get the host extracted
  properly.  Reported and fixed by Kai Sommerfeld.

Daniel (9 December 2004)
- Ton Voon provided a configure fix that should fix the notorious (mostly
  reported on Solaris) problem where the size_t check fails due to the SSL
  libs being found in a dir not searched through by the run-time linker.
  patch-tracker entry #1081707.

- Bryan Henderson pointed out in bug report #1081788 that the curl-config
  --vernum output wasn't zero prefixed properly (as claimed in documentation).
  This is fixed in maketgz now.

Daniel (8 December 2004)
- Matt Veenstra updated the mach-O framework files for Mac OS X.

- Rene Bernhardt found and fixed a buffer overrun in the NTLM code, where
  libcurl always and unconditionally overwrote a stack-based array with 3 zero
  bytes. This is not an exploitable buffer overflow. No need to get alarmed.

Daniel (7 December 2004)
- Fixed so that the final error message is sent to the verbose info "stream"
  even if no errorbuffer is set.

Daniel (6 December 2004)
- Dan Fandrich added the --disable-cookies option to configure to build
  libcurl without cookie support. This is mainly useful if you want to build a
  minimalistic libcurl with no cookies support at all. Like for embedded
  systems or similar.

- Richard Atterer fixed libcurl's way of dealing with the EPSV
  response. Previously, libcurl would re-resolve the host name with the new
  port number and attempt to connect to that, while it should use the IP from
  the control channel. This bug made it hard to EPSV from an FTP server with
  multiple IP addresses!

Daniel (3 December 2004)
- Bug report #1078066: when a chunked transfer was pre-maturely closed exactly
  at a chunk boundary it was not considered an error and thus went unnoticed.
  Fixed by Maurice Barnum.

  Added test case 207 to verify.

Daniel (2 December 2004)
- Fixed the CONNECT loop to default timeout to 3600 seconds.

  Added test case 206 that makes CONNECT with Digest.

  Fixed a flaw that prepended "(nil)" to the initial CONNECT rqeuest's user-
  agent field.

Daniel (30 November 2004)
- Dan Fandrich's fix for libz 1.1 and "extra field" usage in a gzip stream

- Dan also helped me with input data to create three more test cases for the
  --compressed option.

Daniel (29 November 2004)
- I improved the test suite to enable binary contents in the tests (by proving
  it base64 encoded), like for testing decompress etc. Added test 220 and 221
  for this purpose. Tests can now also depend on libz to run.

- As reported by Reinout van Schouwen in Mandrake's bug tracker bug 12285
  (http://qa.mandrakesoft.com/show_bug.cgi?id=12285), when connecting to an
  IPv6 host with FTP, --disable-epsv (or --disable-eprt) effectively disables
  the ability to transfer a file. Now, when connected to an FTP server with
  IPv6, these FTP commands can't be disabled even if asked to with the
  available libcurl options.

Daniel (26 November 2004)
- As reported in Mandrake's bug tracker bug 12289
  (http://qa.mandrakesoft.com/show_bug.cgi?id=12289), curl would print a
  newline to "finish" the progress meter after each redirect and not only
  after a completed transfer.

Daniel (25 November 2004)
- FTP improvements:

  If EPSV, EPRT or LPRT is tried and doesn't work, it will not be retried on
  the same server again even if a following request is made using a persistent
  connection.

  If a second request is made to a server, requesting a file from the same
  directory as the previous request operated on, libcurl will no longer make
  that long series of CWD commands just to end up on the same spot. Note that
  this is only for *exactly* the same dir. There is still room for improvements
  to optimize the CWD-sending when the dirs are only slightly different.

  Added test 210, 211 and 212 to verify these changes. Had to improve the
  test script too and added a new primitive to the test file format.

Daniel (24 November 2004)
- Andrés García fixed the configure script to detect select properly when run
  with Msys/Mingw on Windows.

Daniel (22 November 2004)
- Made HTTP PUT and POST requests no longer use HEAD when doing multi-pass
  auth negotiation (NTLM, Digest and Negotiate), but instead use the request
  keyword "properly". Details in lib/README.httpauth. This also introduces
  CURLOPT_IOCTLFUNCTION and CURLOPT_IOCTLDATA, to be used by apps that use the
  "any" auth alternative as then libcurl may need to send the PUT/POST data
  more than once and thus may need to ask the app to "rewind" the read data
  stream to start.

  See also the new example using this: docs/examples/anyauthput.c

- David Phillips enhanced test 518. I made it depend on a "feature" so that
  systems without getrlimit() won't attempt to test 518. configure now checks
  for getrlimit() and setrlimit() for this test case.

Daniel (18 November 2004)
- David Phillips fixed libcurl to not crash anymore when more than FD_SETSIZE
  file descriptors are in use. Test case 518 added to verify.

Daniel (15 November 2004)
- To test my fix for the CURLINFO_REDIRECT_TIME bug, I added time_redirect and
  num_redirects support to the -w writeout option for the command line tool.

- Wojciech Zwiefka found out that CURLINFO_REDIRECT_TIME didn't work as
  documented.

Daniel (12 November 2004)
- Gisle Vanem modigied the MSVC and Netware makefiles to build without
  libcurl.def

- Dan Fandrich added the --disable-crypto-auth option to configure to allow
  libcurl to build without Digest support. (I figure it should also explicitly
  disable Negotiate and NTLM.)

-                 *** Modified Behaviour Alert ***

  Setting CURLOPT_POSTFIELDS to NULL will no longer do a GET.

  Setting CURLOPT_POSTFIELDS to "" will send a zero byte POST and setting
  CURLOPT_POSTFIELDS to NULL and CURLOPT_POSTFIELDSIZE to zero will also make
  a zero byte POST. Added test case 515 to verify this.

  Setting CURLOPT_HTTPPOST to NULL makes a zero byte post. Added test case 516
  to verify this.

  CURLOPT_POSTFIELDSIZE must now be set to -1 to signal "we don't know".
  Setting it to zero simply says this is a zero byte POST.

  When providing POST data with a read callback, setting the size up front
  is now made with CURLOPT_POSTFIELDSIZE and not with CURLOPT_INFILESIZE.

Daniel (11 November 2004)
- Dan Fandrich added --disable-verbose to the configure script to allow builds
  without verbose strings in the code, to save some 12KB space. Makes sense
  only for systems with very little memory resources.

- Jeff Phillips found out that a date string with a year beyond 2038 could
  crash the new date parser on systems with 32bit time_t. We now check for
  this case and deal with it.

Daniel (10 November 2004)
- I installed Heimdal on my Debian box (using the debian package) and noticed
  that configure --with-gssapi failed to create a nice build. Fixed now.

Daniel (9 November 2004)
- Gisle Vanem marked all external function calls with CURL_EXTERN so that now
  the Windows, Netware and other builds no longer need libcurl.def or similar
  files.

Daniel (8 November 2004)
- Made the configure script check for tld.h if libidn was detected, since
  libidn 0.3.X didn't have such a header and we don't work with anything
  before libidn 0.4.1 anyway! Suse 9.1 apparently ships with a 0.3.X version
  of libidn which makes the curl 7.12.2 build fail. Jean-Philippe
  Barrette-LaPierre helped pointing this out.

- Ian Gulliver reported in debian bug report #278691: if curl is invoked in an
  environment where stderr is closed the -v output will still be sent to file
  descriptor 2 which then might be the network socket handle! Now we have a
  weird hack instead that attempts to make sure that file descriptor 2 is
  opened (with a call to pipe()) before libcurl is called to do the transfer.
  configure now checks for pipe() and systems without pipe don't get the weird
  hack done.

Daniel (5 November 2004)
- Tim Sneddon made libcurl send no more than 64K in a single first chunk when
  doing a huge POST on VMS, as this is a system limitation. Default on general
  systems is 100K.

Daniel (4 November 2004)
- Andres Garcia made it build on mingw againa, my --retry code broke the build.

Daniel (2 November 2004)
- Added --retry-max-time that allows a maximum time that may not have been
  reached for a retry to be made. If not set there is no maximum time, only
  the amount of retries set with --retry.

- Paul Nolan provided a patch to make libcurl build nicely on Windows CE.

Daniel (1 November 2004)
- When cross-compiling, the configure script no longer attempts to use
  pkg-config on the build host in order to detect OpenSSL compiler options.

Daniel (27 October 2004)
- Dan Fandrich:

  An improvement to the gzip handling of libcurl. There were two problems with
  the old version: it was possible for a malicious gzip file to cause libcurl
  to leak memory, as a buffer was malloced to hold the header and never freed
  if the header ended with no file contents.  The second problem is that the
  64 KiB decompression buffer was allocated on the stack, which caused
  unexpectedly high stack usage and overflowed the stack on some systems
  (someone complained about that in the mailing list about a year ago).

  Both problems are fixed by this patch. The first one is fixed when a recent
  (1.2) version of zlib is used, as it takes care of gzip header parsing
  itself.  A check for the version number is done at run-time and libcurl uses
  that feature if it's present. I've created a define OLD_ZLIB_SUPPORT that
  can be commented out to save some code space if libcurl is guaranteed to be
  using a 1.2 version of zlib.

  The second problem is solved by dynamically allocating the memory buffer
  instead of storing it on the stack. The allocation/free is done for every
  incoming packet, which is suboptimal, but should be dwarfed by the actual
  decompression computation.

  I've also factored out some common code between deflate and gzip to reduce
  the code footprint somewhat.  I've tested the gzip code on a few test files
  and I tried deflate using the freshmeat.net server, and it all looks OK. I
  didn't try running it with valgrind, however.

- Added a --retry option to curl that takes a numerical option for the number
  of times the operation should be retried. It is retried if a transient error
  is detected or if a timeout occurred. By default, it will first wait one
  second between the retries and then double the delay time between each retry
  until the delay time is ten minutes which then will be the delay time
  between all forthcoming retries. You can set a static delay time with
  "--retry-delay [num]" where [num] is the number of seconds to wait between
  each retry.

Daniel (25 October 2004)
- Tomas Pospisek filed bug report #1053287 that proved -C - and --fail on a
  file that was already completely downloaded caused an error, while it
  doesn't if you don't use --fail! I added test case 194 to verify the fix.
  Grrr. CURLOPT_FAILONERROR is now added to the list stuff to remove in
  libcurl v8 due to all the kludges needed to support it.

- Mohun Biswas found out that formposting a zero-byte file didn't work very
  good. I fixed.

Daniel (19 October 2004)
- Alexander Krasnostavsky made it possible to make FTP 3rd party transfers
  with both source and destination being the same host. It can be useful if
  you want to move a file on a server or similar.

- Guillaume Arluison added CURLINFO_NUM_CONNECTS to allow an app to figure
  out how many new connects a previous transfer required.

  I added %{num_connects} to the curl tool and added test case 192 and 193
  to verify the new code.

Daniel (18 October 2004)
- Peter Wullinger pointed out that curl should call setlocale() properly to
  initiate the specific language operations, to make the IDN stuff work
  better.

Version 7.12.2 (18 October 2004)

Daniel (16 October 2004)
- Alexander Krasnostavsky made the CURLOPT_FTP_CREATE_MISSING_DIRS option work
  fine even for third party transfers.

- runekl at opoint.com found out (and provided a fix) that libcurl leaked
  memory for cookies with the "max-age" field set.

Gisle (16 October 2004)
- Issue 50 in TODO-RELEASE; Added Traian Nicolescu's patches for threaded
  resolver on Windows. Plugged some potential handle and memory leaks.

Daniel (14 October 2004)
- Eric Vergnaud pointed out that libcurl didn't treat ?-letters in the user
  name and password fields properly in URLs, like
  ftp://us?er:pass?word@site.com/. Added test 191 to verify the fix.

Daniel (11 October 2004)
- libcurl now uses SO_NOSIGPIPE for systems that support it (Mac OS X 10.2 or
  later is one) to inhibit the SIGPIPE signal when writing to a socket while
  the peer dies. The same effect is provide by the MSG_NOSIGNAL parameter to
  send() on other systems. Alan Pinstein verified the fix.

Daniel (10 October 2004)
- Systems with 64bit longs no longer use strtoll() or our strtoll- replacement
  to parse 64 bit numbers. strtol() works fine. Added a configure check to
  detect if [constant]LL works and if so, use that in the strtoll replacement
  code to work around compiler warnings reported by Andy Cedilnik.

Gisle (6 October 2004)
- For USE_LIBIDN builds: Added Top-Level-Domain (TLD) check of host-name
  used in fix_hostname(). Checks if characters in 'host->name' (indirectly
  via 'ace_hostname') are legal according to the TLD tables in libidn.

Daniel (6 October 2004)
- Chih-Chung Chang reported that if you use CURLOPT_RESUME_FROM and enabled
  CURLOPT_FOLLOWLOCATION, libcurl reported error if a redirect happened even
  if the new URL would provide the resumed file. Test case 188 added to verify
  the fix (together with existing test 99).

- Dan Fandrich fixed a configure flaw for systems that need both nsl and socket
  libs to use gethostbyname().

- Removed tabs and trailing whitespace from lots of source files.

Daniel (5 October 2004)
- Made configure --with-libidn=PATH try the given PATH before the default
  paths to make it possible to override.

- If idna_strerror() is present in libidn, we can use that instead of our
  internal replacement. This function was added by Simon in libidn 0.5.6 and
  is detected by configure.

- It seems basename() on IRIX is in the libgen library and since we don't use
  that, configure finds libgen.h but not basename and then we get a compiler
  error because our basename() replacement doesn't match the proto in
  libgen.h. Starting now, we don't include the file if basename wasn't found
  as well.

Daniel (4 October 2004)
- Chris found a race condition resulting in CURLE_COULDNT_RESOLVE_HOST and
  potential crash, in the windows threaded name resolver code.

Daniel (3 October 2004)
- Replaced the use of isspace() in cookie.c with our own version instead since
  we have most data as 'char *' and that makes us pass in negative values if
  there is 8bit data in the string. Changing to unsigned causes too much
  warnings or too many required typecasts to the normal string functions.
  Harshal Pradhan identified this problem.

Daniel (2 October 2004)
- Bertrand Demiddelaer found a case where libcurl could read already freed
  data when CURLOPT_VERBOSE is used and a (very) persistent connection. It
  happened when the dns cache entry for the connection was pruned while the
  connection was still alive and then again re-used. We worked together on
  this fix.

- Gisle Vanem provided code that displays an error message when the (libidn
  based) IDN conversion fails. This is really due to a missing suitable
  function in the libidn API that I hope we can remove once libidn gets a
  function like this.

Daniel (1 October 2004)
- Aleksandar Milivojevic reported a problem in the Redhat bugzilla (see
  https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=134133) and not to
  anyone involved in the curl project! This happens when you try to curl a
  file from a proftpd site using SSL. It seems proftpd sends a somewhat
  unorthodox response code (232 instead of 230). I relaxed the response code
  check to deal with this and similar cases.

- Based on Fedor Karpelevitch's formpost path basename patch, file parts in
  formposts no longer include the path part. If you _really_ want them, you
  must provide your preferred full file name with CURLFORM_FILENAME.

  Added detection for libgen.h and basename() to configure. My custom
  basename() replacement function for systems without it, might be a bit too
  naive...

  Updated 6 test cases to make them work with the stripped paths.

Daniel (30 September 2004)
- Larry Campbell added CURLINFO_OS_ERRNO to curl_easy_getinfo() that allows an
  app to retrieve the errno variable after a (connect) failure. It will make
  sense to provide this for more failures in a more generic way, but let's
  start like this.

- Günter Knauf and Casey O'Donnell worked out an extra #if condition for the
  curl/multi.h header to work better in winsock-using apps.

- Jean-Philippe Barrette-LaPierre made buildconf run better on Mac OS X by
  properly using glibtoolize instead of plain libtoolize. (This is made if
  glibtool was found and used instead of plain libtool.)

Daniel (29 September 2004)
- Bertrand Demiddelaer fixed curl_easy_reset() so that it doesn't mistakingly
  enable the progress meter.

Daniel (28 September 2004)
- "Mekonikum" found out that if you built curl without SSL support, although
  your current SSL installation supports Engine, the compile fails.

Daniel (27 September 2004)
- When --with-ssl=PATH is used to the configure script, it no longer uses
  pkg-config to figure out extra details. That is now only done if no PATH is
  included or if SSL is checked for by default without the --with-ssl option.

Daniel (25 September 2004)
- Peter Sylvester pointed out that CURLOPT_SSLENGINE couldn't even be set to
  NULL when no engine was supported. It can now.

Daniel (22 September 2004)
- Dan Fandrich fixed three test cases to no longer use "localhost" but instead
  use "127.0.0.1" to avoid requiring that localhost resolves nicely.

- Jean-Claude Chauve fixed an LDAP crash when more than one record was
  retrieved.

Daniel (19 September 2004)
- Andreas Rieke pointed out that when attempting to connect to a host without
  a service on the specified port, curl_easy_perform() didn't properly provide
  an error message in the CURLOPT_ERRORBUFFER buffer.

Daniel (16 September 2004)
- Daniel at touchtunes uses the FTP+SSL server "BSDFTPD-SSL from
  http://bsdftpd-ssl.sc.ru/" which accordingly doesn't properly work with curl
  when "AUTH SSL" is issued (although the server responds fine and everything)
  but requires that curl issues "AUTH TLS" instead. See
  https://curl.haxx.se/feedback/display.cgi?id=10951944937603&support=yes

  Introducing CURLOPT_FTPSSLAUTH that allows the application to select which
  of the AUTH strings to attempt first.

- Anonymous filed bug report #1029478 which identified a bug when you 1) used
  a URL without properly seperating the host name and the parameters with a
  slash. 2) the URL had parameters to the right of a ? that contains a slash
  3) curl was told to follow Location:s 4) the request got a response that
  contained a Location: to redirect to "/dir". curl then appended the new path
  on the wrong position of the original URL.

  Test case 187 was added to verify that this was fixed properly.

Daniel (11 September 2004)
- Added parsedate.c that contains a rewrite of the date parser currently
  provided by getdate.y. The new one is MUCH smaller and will allow us to run
  away from the yacc/bison jungle. It is also slightly lacking in features
  compared to the old one, but it supports parsing of all date formats HTTP
  involves (and a fair bunch of others).

Daniel (10 September 2004)
- As found out by Jonas Forsman, curl didn't allow -F to set Content-Type on
  text-parts. Starting now, we can do -F "name=daniel;type=text/extra". Added
  test case 186 to verify.

- Bug report #1025986. When following a Location: with a custom Host: header
  replacement, curl only replaced the Host: header on the initial request
  and didn't replace it on the following ones. This resulted in requests with
  two Host: headers.

  Now, curl checks if the location is on the same host as the initial request
  and then continues to replace the Host: header. And when it moves to another
  host, it doesn't replace the Host: header but it also doesn't make the
  second Host: header get used in the request.

  This change is verified by the two new test cases 184 and 185.

Daniel (8 September 2004)
- Modified the test suite to be able to use and run with customized port
  numbers. This was always intended but never before possible. Now a simple
  change in the runtests.pl script can make all tests use different ports.
  The default ports in use from now on are 8990 to 8993.

Daniel (2 September 2004)
- Minor modification of an SSL-related error message.

Daniel (31 August 2004)
- David Tarendash found out that curl_multi_add_handle() returned
  CURLM_CALL_MULTI_PERFORM instead of CURLM_OK.

Daniel (30 August 2004)
- Make "Proxy-Connection: close" close the current proxy connection, as Roman
  Koifman found out.

Daniel (24 August 2004)
- Fixed a getdate problem by post-replacing the getdate.c file after the
  bison/yacc process to add the fix Harshal Pradhan suggested. The problem
  caused a crash on Windows when parsing some dates.

Daniel (23 August 2004)
- Roman Koifman pointed out that libcurl send Expect: 100-continue on POSTs
  even when told to use HTTP 1.0, which is not correct. Test case 180 and
  181 verify this.

- Added test case 182 to verify that zero byte transfers call the callback
  properly.

Daniel (20 August 2004)
- Alexander Krasnostavsky made the write callback get called even when a zero
  byte file is downloaded.

Daniel (18 August 2004)
- Ling Thio pointed out that when libcurl is built IPv6-enabled, it still did
  reverse DNS lookups when fed with a numerical IP-address (like
  http://127.0.0.1/), although it doesn't when built IPv6-disabled. libcurl
  should never do reverse lookups.

Daniel (17 August 2004)
- Kjetil Jacobsen noticed that when transferring a file:// URL pointing to an
  empty file, libcurl would return with the file still open.

- Alexander Krasnostavsky pointed out that the configure script needs to define
  _THREAD_SAFE for AIX systems to make libcurl built really thread-safe.

  Also added a check for the xlc compiler on AIX, and if that is detect we use
  the -qthreaded compiler option

Daniel (16 August 2004)
- libcurl now allows a custom "Accept-Encoding:" header override the
  internally set one that gets set with CURLOPT_ENCODING. Pointed out by Alex.

- Roland Krikava found and fixed a cookie problem when using a proxy (the
  path matching was wrong). I added test case 179 to verify that we now do
  right.

Daniel (15 August 2004)
- Casey O'Donnell fixed some MSVC makefile targets to link properly.

Daniel (11 August 2004)
- configure now defines _XOPEN_SOURCE to 500 on systems that need it to build
  warning-free (the only known one so far is non-gcc builds on 64bit SGI
  IRIX). (Reverted this change later as it caused compiler errors.)

- the FTP code now includes the server response in the error message when the
  server gives back a 530 after the password is provided, as it isn't
  necessary because of a bad user name or password.

Version 7.12.1 (10 August 2004)

Daniel (10 August 2004)
- In OpenSSL 0.9.7d and earlier, ASN1_STRING_to_UTF8 fails if the input is
  already UTF-8 encoded. This made the certificate verification fail if the
  remote server used a certificate with the name UTF-8 encoded.

  Work-around brought by Alexis S. L. Carvalho.

Daniel (9 August 2004)
- I fixed the configure script for krb4 to use -lcom_err as well, as I started
  to get link problems with it unless I did that on my Solaris 2.7 box. I
  don't understand why I started to get problems with this now!

Daniel (5 August 2004)
- Enrico Scholz fixed the HTTP-Negotiate service name to be uppercase as
  reported in bug report #1004105

Daniel (4 August 2004)
- Gisle Vanem provided a fix for the multi interface and connecting to a host
  using multiple IP (bad) addresses.

- Dylan Salisbury made libcurl no longer accept cookies set to a TLD only (it
  previously allowed that on the seven three-letter domains).

Daniel (31 July 2004)
- Joel Chen reported that the digest code assumed quotes around the contents a
  bit too much.

Daniel (28 July 2004)
- Bertrand Demiddelaer fixed the host name to get setup properly even when a
  connection is re-used, when a proxy is in use. Previously the wrong Host:
  header could get sent when re-using a proxy connection to a different target
  host.

- Fixed Brian Akins' reported problems with duplicate Host: headers on re-used
  connections. If you attempted to replace the Host: header in the second
  request, you got two such headers!

- src/Makefile.am now includes the Makefile.inc file to get info about files

Daniel (26 July 2004)
- Made "curl [URL] -o name#2" work as expected. If there's no globbing for the
  #-number, it will simply be used as #2 in the file name.

- Bertrand Demiddelaer fixed testing with valgrind 2.1.x and added two missing
  newlines in the cookie informationals.

Daniel (24 July 2004)
- I fixed the autobuilds with ares, since they now need to have buildconf run
  in the ares dir before the configure script is run.

- Added Casey O'Donnell's curl_easy_reset() function. It has a proto in
  curl/curl.h but we have no man page yet.

Daniel (20 July 2004)
- Added buildconf and buildconf.bat to the release archives, since they are
  handy for rebuilding curl when using a daily snapshot (and not a pure CVS
  checkout).

Daniel (16 July 2004)
- As suggested by Toby Peterson, libcurl now ignores Content-Length data if the
  given size is a negative number. Test case 178 verifies this.

Daniel (14 July 2004)
- Günter Knauf has made the Netware builds do without the config-netware.h
  files, so they are now removed from the dist packages.

- Günter Knauf made curl and libcurl build with Borland again.

- Andres Garcia fixed the common test 505 failures on windows.

Daniel (6 July 2004)
- Andrés García found out why the windows tests failed on file:// "uploads".

Daniel (2 July 2004)
- Andrés García reported a curl_share_cleanup() crash that occurs when no
  lock/unlock callbacks have been set and the share is cleaned up.

Daniel (1 July 2004)
- When using curl --trace or --trace-ascii, no trace messages that were sent
  by curl_easy_cleanup() were included in the trace file. This made the
  message "Closing connection #0" never appear in trace dumps.

Daniel (30 June 2004)
- Niels van Tongeren found that setting CURLOPT_NOBODY to TRUE doesn't disable
  a previously set POST request, making a very odd request get sent (unless
  you disabled the POST) a HEAD request with a POST request-body. I've now
  made CURLOPT_NOBODY enforce a proper HEAD. Added test case 514 for this.

Daniel (29 June 2004)
- Günter Knauf made the testcurl.pl script capable of using a custom setup
  file to easier run multiple autobuilds on the same source tree.

- Gisle fixed the djgpp build and fixed a memory problem in some of the
  reorged name resolved code.

- Fixed code to allow connects done using the multi interface to attempt the
  next IP when connecting to a host that resolves to multiple IPs and a
  connect attempt fails.

Daniel (27 June 2004)
- Based on Rob Stanzel's bug report #979480, I wrote a configure check that
  checks if poll() can be used to wait on NULL as otherwise select() should be
  used to do it. The select() usage was also fixed according to his report.

  Mac OS X 10.3 says "poll() functionality for Mac OS X is implemented via an
  emulation layer on top of select(), not in the kernel directly. It is
  recommended that programs running under OS X 10.3 prefer select() over
  poll(). Configure scripts should look for the _POLL_EMUL_H_ define (instead
  of _POLL_H_ or _SYS_POLL_H_) and avoid implementations where poll is not
  implemented in the kernel."

  Yes, we can probably use select() on most platforms but today I prefered to
  leave the code unaltered.

Daniel (24 June 2004)
- The standard curl_version() string now only includes version info about
  involved libraries and not about particular features. Thus it will no longer
  include info about IPv6 nor GSS. That info is of course still available in
  the feature bitmask curl_version_info() offers.

- Replaced all occurances of sprintf() with snprintf(). This is mostly because
  it is "A Good Thing" rather than actually fixing any known problem. This
  will help preventing future possible mistakes to cause buffer overflows.

- Major reorganization in the host resolve code (again). This time, I've
  modified the code to now always use a linked list of Curl_addrinfo structs
  to return resolved info in, no matter what resolver method or support that
  is available on the platform. It makes it a lot easier to write code that
  uses or depends on resolved data.

  Internally, this means amongst other things that we can stop doing the weird
  "increase buffer size until it works" trick when resolving hosts on
  IPv4-only with gethostbyname_r(), we support socks even on libcurls built
  with IPv6 enabled (but only to socks servers that resolve to an IPv4
  address) and we no longer deep-copy or relocate hostent structs (we create
  Curl_addrinfo chains instead).

  The new "hostent to Curl_addrinfo" converter function is named Curl_he2ai()
  and is slightly naive and simple, yet I believe it is functional enough to
  work for libcurl.

Daniel (22 June 2004)
- David Cohen pointed out that RFC2109 says clients should allow cookies to
  contain least 4096 bytes while libcurl only allowed 2047. I raised the limit
  to 4999 now and made the used buffer get malloc()ed instead of simply
  allocated on stack as before. Extended test case 46 to include a cookie with
  very huge content to verify the fix.

- Günter Knauf fixed getdate.y to remove a few warnings. I removed the
  ifdef'ed test we never ever use anyway.

- Gisle Vanem fixed the certificate wildcard checks to support a '*'-letter
  anywhere in the wildcard string, support multiple '*'-letters in the
  wildcard and to allow the '*'-letter to match a string that includes a dot.

Daniel (21 June 2004)
- testcurl.sh is now removed completely, tests/testcurl.pl is the script to
  use when autobuilding curl!

- Kjetil Jacobsen brought my attention to the fact that you cannot properly
  abort an upload with the readfunction callback, since returning 0 or -1 only
  stops the upload and libcurl will continue waiting for downloaded data and
  the server often waits for the rest of the upload data to arrive.

  Thus, I've now added the ability for read callbacks to return
  CURL_READFUNC_ABORT to abort an upload from a read callback. This will stop
  the transfer immediately with a CURLE_ABORTED_BY_CALLBACK return code.

  Test case 513 was added to verify that it works. I had to improve the test
  HTTP server too to dump the request to a file even when the client
  disconnects prematurely.

Daniel (19 June 2004)
- Luca Alteas provided a test case with a failing curl operation: when we POST
  to a site with --digest (or similar) set, and the server responded with a 302
  Location: to the "authprobe" request, it was not treated correctly. We still
  will behave badly if FOLLOWLOCATION is enabled for this case, but I'm not
  in the mood to dive into this right now and will leave it as-is for now.
  Verified my fix with test case 177.

Daniel (18 June 2004)
- Gisle Vanem's patch that provides more details from the SSL layers (if you
  use an OpenSSL version that supports it). It also introduces two new types
  of data that can be sent to the debug callback: CURLINFO_SSL_DATA_IN and
  CURLINFO_SSL_DATA_OUT.

- With David Byron's test server I could repeat his problem and make sure that
  POSTing over HTTPS:// with NTLM works fine now. There was a general problem
  with multi-pass authentication with non-GET operations with CONNECT.

Daniel (16 June 2004)
- Modified to keep the upload byte counter in an curl_off_t, not an int as
  before. 32bits is not enough. This is most likely the bug Jean-Louis Lemaire
  reported that makes 2GB FTP uploads to report error ("unaligned file sizes")
  when completed.

Daniel (15 June 2004)
- Luca Alteas reported a problem that I fixed: if you did a POST with
  CURLAUTH_DIGEST set but the server didn't require any authentication,
  libcurl would repeatedly send HEAD lots of times until it gives up. This was
  actually the case for all multi-pass authentications. Added test case 174,
  175 and 176 to verify this.

Daniel (14 June 2004)
- Multipart formposts uploading files no longer inserts the files themselves
  into the huge prebuilt chunk. This enables libcurl to formpost files that is
  larger than the amount of system memory. When the file given is passed on
  stdin, libcurl still uses the old method of reading the full fill before the
  upload takes place. This approach was selected in order to not alter the
  behavior for existing applications, as when using stdin libcurl can't know
  the size of the upload and chunked transfer-encoding can only be used on
  HTTP 1.1 servers.

Daniel (13 June 2004)
- Gisle found out that we did wildcard cert name checks wrong, so that parts
  of the check wrongly was case sensitive.

Daniel (11 June 2004)
- Tim Sneddon brought a minor VMS fix to make curl build properly on his VMS
  machine. He also had some interesting libcurl patches... they might be able
  to do in a slightly nicer way. Discussions are in progress.

Daniel (10 June 2004)
- Gisle Vanem brought code cleanupsm better verbose output and better connect
  timeout handling when attempting to connect to a host that resolves to
  multiple IP addresses.

- Steven Bazyl and Seshubabu Pasam pointed out a bug on win32 when freeing the
  path after a file:// transfer.

Daniel (9 June 2004)
- Alexander Krasnostavsky made 'configure --disable-http' work to build libcurl
  without HTTP support. I added a new return code for curl_formadd() in case
  libcurl is built with HTTP disable: CURL_FORMADD_DISABLED.

- Alexander Krasnostavsky pointed out a missing file in the generated
  curllib.dsp file, and now people building with this should get a libcurl.lib
  file generated as it used to do before we generated this file.

Daniel (8 June 2004)
- Marty Kuhrt fixed a minor build problem for VMS.

Daniel (7 June 2004)
- Reverted the configure check from the 4th since it obviously didn't work.
  Remade it in a different manner that hopefully works better.

Daniel (4 June 2004)
- Günter Knauf brought patches to make curl build fine on NetWare again.

- Made the configure checks for strerror_r() not exit the configure script
  when built for cross-compiling.

Daniel (3 June 2004)
- Chris Gaukroger pointed out that 'make test' attempts to run the tests even
  if curl is built cross-compiled. I've now made it output a short message
  instead, saying it isn't possible to do.

- Alexander Krasnostavsky brought FTP 3rd party transfer support to libcurl.
  You can now use libcurl to transfer files between two remote hosts using
  FTP. There are a bunch of new options to control this with:
   CURLOPT_SOURCE_HOST
   CURLOPT_SOURCE_USERPWD
   CURLOPT_SOURCE_PATH
   CURLOPT_SOURCE_PORT
   CURLOPT_PASV_HOST
   CURLOPT_SOURCE_PREQUOTE
   CURLOPT_SOURCE_POSTQUOTE

  (They still remain to be documented properly in the curl_easy_setopt man
  page.)

  When using this, the ordinary CURLOPT_URL specifies the target URL, and you
  specify the source data with these additional options. ftp3rdparty.c is a
  new example source code showing how to use this.

- Vincent Bronner fixed the HTTP Digest code to use the proxy user name and
  password when doing proxy authentication, it previously always used the host
  user name and password!

Daniel (2 June 2004)
- CURLOPT_UPLOAD and CURLOPT_PUT now do the exact same thing internally, which
  fixes some old confusions on when which of these should be used and what the
  differences are.

- Applied Gisle's fixes to make curl build fine with lcc-win32

Version 7.12.0 (2 June 2004)

Daniel (1 June 2004)
- I clarified the --create-dirs option somewhat in the curl man page.

- Renaud Duhaut corrected the curl_unescape man page.

- David Byron modified one of Massimiliano Ziccardi's recent MSVC makefile
  changes to now again use the mm lib by default.

Daniel (26 May 2004)
- Mohun Biswas added release-zlib and debug-zlib targets to the MSVC libcurl
  Makefile

- David Byron reported a problem with proxy authentication when doing CONNECT,
  like when accessing HTTPS sites wiht a proxy. This probably broke when I
  rewrote the auth stuff recently.

- I added fileupload.c in the examples directory, showing how an upload to a
  file:// URL is made.

Daniel (25 May 2004)
- Massimiliano Ziccardi updated the MSVC makefiles.

Daniel (24 May 2004)
- libcurl now supports "uploading" to file:// URLs. Test 204 and 205 were
  added to verify.

- Simon Josefsson added a idn_free() function in libidn 0.4.5 as a reaction to
  Gisle's previous mail. We now use this function, and thus we require libidn
  0.4.5 or later. No earlier version will do.

- Robert D. Young reported that CURLOPT_COOKIEFILE and CURLOPT_COOKIE could
  not be used both in one request. Fixed it and added test case 172 to verify.

Daniel (21 May 2004)
- While talking to host a.b.c, libcurl did wrongly not accept cookies that
  were set to the domain .a.b.c (that is with a dot prefix). This is now fixed
  and test case 171 verifies it.

Daniel (20 May 2004)
- Jesse Noller reported that the upload speed info reported by libcurl was
  wrong. The same was true for the download speed. Fixed now.

Daniel (19 May 2004)
- David Byron added test case 170 - this used to crash the previous version of
  curl.

Daniel (17 May 2004)
- Peter Sylvester's patch that addresses two flaws in the peer certificate
  name verification:
  o when multiple common names are used (as in the curl tests), the last name
    needs to be selected.
  o allow comparing with encoded values, at least with BMP and ISO latin1
    encoded T61strings.

- All 191 test cases run through the torture test OK! 'make test-torture' is
  now available in the root makefile (on configure-based environments).

Daniel (14 May 2004)
- With a slightly modified ftpserver.pl I've now run almost all tests through
  with runtests.pl -t. This is goodness!

- Since I have been unable to contact the CVS admins for several months, I've
  decided that the current CVS hosting was not good enough. I've now moved the
  CVS repo once again, see README for updated cvs checkout instructions.

Daniel (13 May 2004)
- runtests.pl -t now runs fine all the way to test 100. I believe test case
  100 fails because of an FTP server problem.

Daniel (12 May 2004)
- General cleanups all over to make libcurl survive and do well when a memory
  function returns NULL. runtests.pl -t now works fine for the first 26 test
  cases.

Daniel (11 May 2004)
- Seshubabu Pasam provided a patch that introduces curl_global_init_mem() -
  like normal curl_global_init() but allows the app to replace all memory
  functions with its own set. I modified it slightly.

- Based on Luca Alteas' comments, I modified the curllib.dsp generation code.

Daniel (10 May 2004)
- Gisle mailed Simon Josefsson (of libidn fame) about the benefits of a
  separate free()-function by that lib to make sure the memory is freed by the
  same memory subsystem that allocated it. He responded positively and this
  will likely cause us to require a newer version of libidn as soon as Simon
  releases one with such a libidn_free() function.

- James Bursa made runtests.pl's -t option work for any given test case, and I
  edited to allow -g too. Not even test case 1 worked...

- Luca Altea made the nc= field not use quotes in outgoing HTTP Digest headers.

- Andrés García fixed a problem in the test script that made it fail to
  recognize our own running HTTP server.

Daniel (7 May 2004)
- James Bursa fixed the memanalyze.pl script to conder malloc(0) areas OK to
  free() and he made two failed-resolve error messages use the new display-
  name instead of the internally-used name.

- Gisle Vanem tried curl with
  www.etdomenenavnkanmaksimaltinneholdesekstitrebokstaversliksomdette.com
  which caused problems, and I fixed the single zero byte buffer overwrite
  that occurred (due to a stupid protocol buffer size and parser).

- Made the lib/curllib.dsp file get generated automaticly when a distribution
  package is made, with the msvcproj.* files as templates and all
  win32-sources added. I think this can be made to work better than the always
  lagging-behind previous approach. I'm not sure this builds a working project
  file right now though!

Daniel (6 May 2004)
- Michael Benedict brought a fix that fills in the errorbuffer properly when
  ares fails to resolve a name for a case not previously dealt with like this.

Daniel (5 May 2004)
- Joe Halpin fixed the annoying typecast warning in lib/ldap.c

- Gisle Vanem fixes:
  o memdebug to not access NULL on several places
  o libcurl.def; curl_formparse is gone.
  o progress.c; fixed the percent values being trunced to 0.
  o if2ip.*; constified the 'interface' argument.

- Tor Arntsen reported that many of his autobuilds froze and I found and fixed
  a problem introduced with the HTTP auth overhaul that could lead to a
  never-ending internal request-loop due to un-initialized variables!

- Removed several compiler warnings on various compilers/platforms.

Daniel (4 May 2004)
- curl_formparse() has been removed from the library. It has been marked and
  mentioned as deprecated for several years.

Daniel (3 May 2004)
- Rewritten HTTP authentication code. The previous code could not properly
  deal with the added test cases 167, 168 and 169. I've now rewritten the code
  to better separate host and proxy authentication and not re-use the same
  variables as much as before as it proved non working in the more involved
  cases. All the current tests run OK now, and so do the new ones. The curl
  tool got a new option named --proxy-digest to enable HTTP Digest
  authentication with the proxy. I also made the library support it.

- Gisle Vanem made the LDAP code work with wldap32.dll as supplied with
  Win-98/ME/2000/XP, so no extra .dlls are required when curl/libcurl is used
  on these Windows versions.

Daniel (30 April 2004)
- runtests.pl now scans the valgrind log for valgrind-detected memory leaks
  after each test case if valgrind was found and used.

- I modified the app-code in curl to include the new lib/curlx.h and only
  access those functions using the curlx_-prefix in preparation for the future
  removal of several curl_-functions from the public libcurl API.

- Introduced lib/curlx.h as a single header to provide the curlx_-functions
  to apps.

- Added notices in the man pages for curl_getenv, curl_mprintf, curl_strequal
  and curl_strnequal that they are subject for removal in a future release.
  STOP USING THESE FUNCTIONS.

- Mihai Ionescu noticed he couldn't do formposts with whitespace in the file
  names and yes, I broke that on April 23. Sigh. I fixed it now and added
  test case 166 to verify it.

- Luca Altea pointed out a mistake left from the Digest patch of yesterday.

Daniel (29 April 2004)
- Made IDN domains work when sending requsts over HTTP proxy as well. Added
  test case 165 to verify the functionality.

- Fixed a bug in the new internal host name setup when re-using connections.

- James Bursa found out that curl_easy_duphandle() with ares-built libcurl
  created a bad handle that would crash in the first name resolve attempt. This
  is now fixed and test case 512 was added to verify it.

- Luca Altea provided a major HTTP Digest code fix and cleanup. We now follow
  the Digest RFC a lot better.

- Gisle Vanem made the SSL code use ERR_error_string_n() where applicable.

Daniel (27 April 2004)
- I remodeled Gisle's IDN code slightly and now we convert both the host name
  and proxy name to the ACE encoded version to use internally for resolves and
  cookies etc. They are now using one 'struct hostname' each that keep both
  the original name and the possibly encoded name. IDN resolves work for me
  now using IPv6, IPv4 and ares resolving. Even cookies on IDN sites seem to
  do right. I got some failures at first when CHARSET wasn't set at all which
  confused libidn completely and it decided by encoding of choice was
  'ANSI_X3.4-1968'...

- made 'configure --without-libidn' work

Daniel (25 April 2004)
- Fixed the src/hugehelp.c file to include "setup.h" instead of "config.h" to
  make the problems with USE_MANUAL on windows go away.

- configure --without-ssl could still wrongly include some OpenSSL info in the
  Makefiles if pkg-config had info about OpenSSL. Bug #941762 reported by
  Martin.

- Since we can now build and use quite a large set of 3rd party libraries, I
  decided I would make configure produce a summary at the end showing what
  libraries it uses and if not, what option to use to make it use that. I also
  added some other random info that is nice in a "configure summary" output.

- Applied TommyTam's patch that now make curl work with telnet and stdin
  properly on Windows.

- The changes for today below were made by me and Gisle Vanem.

  The file previously known as hostip.c has now undergone a huge cleanup and
  split:

  hostip.c explained
  ==================

  The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
  source file are these:

  CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
  that. The host may not be able to resolve IPv6, but we don't really have to
  take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
  defined.

  CURLRES_ARES - is defined if libcurl is built to use c-ares for asynchronous
  name resolves. It cannot have ENABLE_IPV6 defined at the same time, as
  c-ares has no IPv6 support. This can be Windows or *nix.

  CURLRES_THREADED - is defined if libcurl is built to run under (native)
  Windows, and then the name resolve will be done in a new thread, and the
  supported asynch API will be the same as for ares-builds.

  If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
  libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
  defined.

  The host*.c sources files are split up like this:

  hostip.c   - method-independent resolver functions and utility functions
  hostasyn.c - functions for asynchronous name resolves
  hostsyn.c  - functions for synchronous name resolves
  hostares.c - functions for ares-using name resolves
  hostthre.c - functions for threaded name resolves
  hostip4.c  - IPv4 specific functions
  hostip6.c  - IPv6 specific functions

  The hostip.h is the single united header file for all this. It defines the
  CURLRES_* defines based on the config*.h and setup.h defines.

- Added function header comments to many functions in an attempt to better
  explain the purpose of them all.

- configure --with-libidn is now supported. It makes the configure script
  check for libidn libs and include files in the prefix path given. If you
  say --with-libidn=/usr/local, it will check for the lib in /usr/local/lib
  and the includes in /usr/local/include etc.

- curl_version_info() now returns a struct aged CURLVERSION_THIRD including
  libidn version info. The string curl_version() returns also includes libidn
  version info, if available.

Version 7.11.2 (26 April 2004)

Daniel (25 April 2004)
- Erwin Authried pointed out that configure --disable-manual didn't do right
  if you already had a src/hugehelp.c source file present (which most people
  do I guess). It now uses the USE_MANUAL define properly.

Daniel (23 April 2004)
- Gisle Vanem found and fixed a memory leak when doing (failing) Windows
  threaded name resolves.

- I also added test case 163 just to make sure -F "var=<file" works fine and
  can pass on characters such as newlines, carriage-return and tabs.

- When we added test case 162 without adding the necessary requirement field
  in the test meta data we could see that curl didn't complain if you used
  --proxy-ntlm even if the underlying libcurl it uses has no NTLM support! I
  now made it check this first, and it now exists with a "the installed
  libcurl version doesn't support this" message if it happens again.

Daniel (22 April 2004)
- David Byron found and fixed a small bug with the --fail and authentication
  stuff added a few weeks ago.  Turns out that if you specify --proxy-ntlm and
  communicate with a proxy that requires basic authentication, the proxy
  properly returns a 407, but the failure detection code doesn't realize it
  should give up, so curl returns with exit code 0. Test case 162 added to
  verify the functionality.

- allow newlines in the contents when doing -F "var=[contents]"
  Robert Marlow reported.

- If a transfer is found out to be only partial, libcurl will now treat that
  as a problem serious enough to skip the final QUIT command before closing
  the control connection. To avoid the risk that it will "hang" waiting for
  the QUIT response. Added test case 161 to verify this.

Daniel (21 April 2004)
- Modified the heuristics for dealing with the test 160 scenario. When a
  connection is re-used and nothing at all is received from it (because the
  server closes the connection), we will now retry the request on a fresh new
  connection. The previous ECONNRESET stuff from January 30 was removed again
  as it didn't detect the situation good enough.

Daniel (20 April 2004)
- Added test case 160 to verify that curl works correctly when it gets a
  connection reset when trying to re-use a connection. It should then simply
  create a new connection and resend the request.

Daniel (19 April 2004)
- No more 512 byte limit for host name (inclusing name + password) in libcurl.
  An added bonus is that we use less memory for the typical (shorter URL)
  case.

- Cleaned up the sources to better use the terms 'hostname' and 'path'
  internally when referring to that data. The buffers used for keep that info
  is called 'namebuffer' and 'pathbuffer'. Much easier to read and understand
  than the previous mess.

Daniel (15 April 2004)
- Modified runtests.pl again to remove all log files in the log/ dir between
  each test, and then made -p display all non-zero byte files in the log dir.
  It should make that data more usable and contain less rubbish.

- ftpserver.pl now produces log files more similar to how the sws ones look
  and they now also contains a bit more details to help debugging ftp
  problems.

- Removed the fixed maximum amount of dir levels the FTP code supported.
  Previously we had a fixed array for 100 levels, now we save space in each
  handle by allocating only for a few level by default and then enlarging that
  in case of need (with no maximum depth). Adjusted test case 142 to verify
  that 150 dir levels work fine.  An added bonus is that we use less memory
  for the typical (not very deep) case.

Daniel (14 April 2004)
- Asking for CURL_IPRESOLVE_V6 when IPv6 addresses can't be resolved will
  now cause the resolve function to return NULL immediately. This flaw was
  pointed out by Gisle Vanem.

- Gisle Vanem made curl -4/-6 actually set the desired option to libcurl.

- runtests.pl now has a new option (-p) that will display "interesting" log
  files to stdout in case of a test failure. This is primarily intended to be
  used in the 'full-test' make target that is used by the autobuild tests, as
  we then get a much better chance to understand (remote) test failures based
  on autobuild logs alone.

Daniel (13 April 2004)
- Gisle Vanem made the multi interface work again on Windows even when built
  without ares. Before this, select() would return -1 during the name resolve
  phase since curl_multi_fdset() didn't return any fd_set at all which wasn't
  appreciated!

- curl_easy_duphandle() now duplicates the tcp_nodelay info as well.

Daniel (11 April 2004)
- Applied David Byron's patch for the MSVC libcurl makefile for builds with
  zlib.

Daniel (9 April 2004)
- Dirk Manske improved the timer resolution for CURLINFO_*_TIME, it can now
  be down to usec if the system sypports it.

Daniel (7 April 2004)
- A request that sends "Expect: 100-continue" and gets nothing but a single
  100 response back will now return a CURLE_GOT_NOTHING. Test 158 verifies.

- The strtoofft() macro is now named curlx_strtoofft() to use the curlx_*
  approach fully.

Daniel (6 April 2004)
- Gisle Vanem's fixed bug #927979 reported by Nathan O'Sullivan. The problem
  made libcurl on Windows leak a small amount of memory in each name resolve
  when not used as a DLL.

- New authentication code added, particularly noticable when doing POST or PUT
  with Digest or NTLM. libcurl will now use HEAD to negotiate the
  authentication and when done perform the requested POST. Previously libcurl
  sent POST immediately and expected the server to reply a final status code
  with an error and then libcurl would not send the request-body but instead
  send then next request in the sequence.

  The reason for this change is due to IIS6 barfing on libcurl when we attempt
  to POST with NTLM authentication. The reason for the problems is found in
  RFC2616 section 8.2.3 regarding how servers should deal with the 100
  continue request-header:

        If it responds with a final status code, it MAY close the transport
        connection or it MAY continue to read and discard the rest of the
        request.

  Previous versions of IIS clearly did close the connection in this case,
  while this newer version decided it should "read and discard". That would've
  forced us to send the whole POST (or PUT) data only to have it discarded and
  then be forced to send it again. To avoid that huge penality, we switch to
  using HEAD until we are authenticated and then send the POST.

  The only actual drawback I can think of (except for the odd sites that might
  treat HEAD differently than they would treat POST/PUT when given the same
  URL) is that if you do POST with CURLAUTH_ANY set and the site requires NO
  authentication, libcurl will still use a HEAD in a first round and then do a
  POST.

  If you do a HEAD or a GET on a site using CURLAUTH_ANY, libcurl will send
  an un-authenticated request at once, which then is the only request if the
  site requires no auth.

  Alan Pinstein helped me work out the protocol details by figuring out why
  libcurl failed and what IIS6 expects.

- The --limit-rate logic was corrected and now it works a lot better for
  higher speeds, such as '10m' or similar. Reported in bug report #930249.

- Introducing curlx_tvnow() and curlx_tvdiff() using the new curlx_* fashion.
  #include "timeval.h" from the lib dir to get the protos etc.  Note that
  these are NOT part of the libcurl API. The curl app simply uses the same
  source files as the library does and therefore the file needs to be compiled
  and linked with curl too, not just when creating libcurl.

- lib/strerror.c no longer uses sys_nerr on non-windows platforms since it
  isn't portable enough

Daniel (2 April 2004)
- In the curl_strnqual.3 man page, we now prepend the man3 dir to the file
  name to work better. As pointed out by Robin Kay.

- Andrés García updated the mingw makefiles.

- Dirk Manske fixed a problem I recently added in the progress meter code that
  broke subsecond resolution for CURLINFO_TOTAL_TIME. He also pointed out a
  mistake in the code that produces the final update of the progress meter
  that would often prevent it from actually being updated that final time.

Daniel (1 April 2004)
- Dirk Manske fixed a memory leak that happened when we use ares for name
  resolves and decides to time-out before ares does it. This fix uses the
  brand new ares_cancel() function which is not present in c-ares 1.1.0.

  When told to enable ares, the configure script now checks for presence of
  the ares_cancel function to alert users if they attempt to use a too old
  c-ares library.

Daniel (31 March 2004)
- Roy Shan fixed a flaw that prevented ares name resolve timeouts to occur!

- Dirk Manske found out that libcurl timed out waiting for resolves far too
  easy when libcurl was built to use (c-)ares for name resolving.

- Further Digest fixing and a successful test case 153 now makes me believe
  Mitz Wark's problems are fixed.

- Andres Garcia figured out that test case 63, while working, only proved a
  flaw in libcurl's 'http_proxy' parser when a user name and password is
  provided. The user name was not extracted properly (and 'http' was always
  used as user name).

- Andrés García fixed compiler warnings in our ioctlsocket() usage.

Daniel (30 March 2004)
- Joe Halpin faced problems with the getnameinfo() argument ai_flags and the
  particular bit named 'NI_WITHSCOPEID' on Solaris 9 for Intel.  I've now
  written a configure test that checks for a working NI_WITHSCOPEID
  implemenation. No code uses the result from this test yet, it is still
  experimental. James Carlson wrote in comp.unix.solaris: "It's a bug
  (5006623) -- it's not supported and shouldn't be in the header file."

- I provided Mitz Wark with a first patch in order to fix libcurl's problems
  to re-negotiate Digest authentication (when 'stale=true' is included in the
  response header).

- Roy Shan discovered that the multi interface didn't properly timeout name
  lookups which could make handles get stuck in that state and thus never get
  completed. I've produced a first test patch that attempts to correct this.

- David Byron's patch was appplied to make CURLOPT_FAILONERROR work nicely
  even with authentcations such as NTLM or Digest enabled. Test cases 150, 151
  and 152 were added to verify the functionality.

Daniel (29 March 2004)
- Gisle Vanem updated files for the djgpp/MS-DOS build.

- Andrés García helped me work out a fix for the runtests.pl script to make
  the file:// tests run fine when tested with the mingw-built version of curl.

- Fixed an include issue with netinet/tcp.h on AIX, based on input by Tor.
  This also required a minor fix of the configure script.

- The postit2.c source example used the wrong struct name for the post data.

Daniel (26 March 2004)
- Gisle Vanem improved IPv6 support on Windows by making the curl build use
  the correct getaddrinfo() function.

Daniel (25 March 2004)
- It turned out that AIX, despite having a "thread-safe libc", doesn't offer
  all traditional functions thread-safe. This URL is informative on this
  subject:

    http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/ \
    genprogc/thread_quick_ref.htm

  As a result of this, we now check for three *_r() functions on recent AIX
  versions as well that the URL mentions aren't thread-safe in AIX 5.1.

- renamed curl_strerror.[ch] to strerror.[ch]

- Joe Halpin added CURLOPT_TCP_NODELAY and --tcp-nodelay to make it possible
  for users to disable the Nagle algorthim-usage.

- Tor Arntsen provided some interesting strerror_r() knowledge. glibc has its
  own API which differs from the POSIX one. Daniel adjusted the configure
  script to detect the version in use, and the code now uses the new defines
  accordingly.

- Fixed some build flaws with the new lib/curl_strerror.c source file.

Daniel (24 March 2004)
- Gisle Vanem's fix to replace the bad use of strerror(). This introduces
  Curl_strerror() that attempts to be thread-safe _and_ works on Windows too!

- Tor Arntsen spell-fixed lots of libcurl man pages.

- Tor Arntsen made testcurl.pl work with older perl 5 versions, and Daniel
  made it not use chdir .. to go back, as that isn't very good when you've
  setup a testdir containing symlinks.

- Added a check for strerror_r() in the configure script.

Daniel (23 March 2004)
- Added Greg Hewgill's testcurl.pl script to CVS. We have not moved over to
  use this script for the real distributed testing just yet, but it is only
  a matter of time.

- Gisle Vanem provided code that makes curl report a better error message
  if --interface fails on windows.

- The regular progress meter is now fixed to never wrap due to long lines. All
  fields are now static sized. If the time in the time fields get a time value
  that would represent a time that is 100 hours or more (if not, it remains
  using a HH:MM:SS display), it switches first to a "NNNd NNh" display (for
  days and hours) and if that isn't enough it switches to a "NNNd" display if
  it is more than 999 days.

  Several of the calculations were also moved to fixed-point math instead of
  using doubles.

Daniel (22 March 2004)
- Glen Nakamura noticed CURLINFO_CONTENT_LENGTH_DOWNLOAD didn't work as it
  used to do if CURLOPT_NOBODY is set TRUE.

- Kevin Roth patched the cygwin package makefile and README to adjust to
  new cygwin packaging guidelines.

- Enabled "NT responses" in the NTLM authentication. Doing this simply means
  that we provide an extra chunk of data in each "type-3 message". The only
  reason for doing this is that it seems that using only the "Lanmanager hash"
  (as we've been doing until now) doesn't support passwords longer than 14
  characters and it turns out there are users out there who want to use
  libcurl and NTLM with such passwords! ;-) Seven NTLM-related test cases were
  updated accordingly. Mentioned as issue 29 in TODO-RELEASE, bug report
  #915609

- Moved the generated libcurl version info to a new header file, named
  curl/curlver.h. Now interested parties can include ONLY version info, should
  anyone want that (and it seems at least some windows resource files would).
  Mentioned as issue 27 in TODO-RELEASE.

Daniel (21 March 2004)
- Fixed the root Makefile to use tabs for the netware target. Günter Knauf
  pointed this out.

- Marty Kuhrt's VMS cleanup

- Thomas Schwinge made buildconf recognize ACLOCAL_FLAGS to invoke aclocal
  with particular pre-determined options.

Version 7.11.1 (19 March 2004)

Daniel (18 March 2004)
- Tor Arntsen brought some info about SGI IRIX:

  IRIX supports 3 different executable/object formats, -32, -n32 and -64.
  -n32 is default 32-bit format, -32 is the "old" 32-bit format, and -64 is
  the 64-bit format.  Libraries for the different formats are in lib, lib32
  and lib64 respectively.

  We've now adjusted the configure script to adapt to this when scanning for
  3rd party libs, such as OpenSSL.

Daniel (17 March 2004)
- Watz pointed out a few missing files in the MSVC project description file.

- Günter Knauf brought patches, code and makefiles to build curl on Novell
  NetWare.

Daniel (15 March 2004)
- Lots of libcurl man pages were updated to contain references to other man
  pages the recognized way so that they appear as nice hyperlinks in the HTML
  versions.

- buildconf now checks the m4 version too, since autoconf requires a GNU m4
  version to build proper configure scripts.

Daniel (12 March 2004)
- Added CURLOPT_POSTFIELDSIZE_LARGE, the large file version of
  CURLOPT_POSTFIELDSIZE to allow POSTs larger than 2GB.

- David Byron fixed an uninitialized variable case/crash.

Daniel (10 March 2004)
- Jeff Lawson fixed the SSL connection to deal with received signals during the
  connect.

- Changed the OS string for win32 to become "i386-pc-win32".

Daniel (9 March 2004)
- Changed the internals to use curl_socket_t for socket variable type. This
  should enable us to build with less warnings on Windows, where SOCKET is
  used which is an unsigned int, while most other platforms use a mere int.

- Modified lib/config-win32.h to build fine on MSVC again.

Version 7.11.1-pre1 (8 March 2004)

Daniel (8 March 2004)
- Minor fix to make curl CURL_VERSION_LARGEFILE is only set if curl_off_t is
  larger than 4 bytes.

Daniel (4 March 2004)
- Improved PUT/POST with NTLM/Digest authentication, the so called issue 12.

- Modified the test HTTP server a lot to work with the upcoming changes for
  PUT/POST with NTLM/Digest authentication (like test case 88). Added Andrés
  García's win32-changes. Improved the logging.

- Fixed the file:-related progress/getinfo stuff a bit more.

Daniel (4 March 2004)
- I corrected a problem with the multi interface when following a Location:
  header or when doing multiple-request authentications. A subsequent request
  could erroneously re-use a previous connection that was sent with
  Connection: close. Christopher R. Palmer reported.

- Andrés García patched curl to prevent warnings while compiling with mingw,
  mainly because it is now possible to have both WIN32 and HAVE_CONFIG_H
  defined.

- When transferring files from a file: URL, the progress meter and other
  transfer metrics were not updated properly.

- David Byron provided a "version resource" file to the curl executable for
  the windows builds.

Daniel (3 March 2004)
- David Byron's work on making libcurl only require winsock 1.1 on Windows
  machines.

- More variable cleanups based on compiler warnings generated by Tor Arntsen's
  autobuilds with MIPSPro.

- Joe Halpin helped us fix some pedantic compiler warnings on FreeBSD.

- Applied Tom Bates' patch to build on nsr-tandem-nsk.

- Dan Fandrich corrected some flaws in the configure GSS detection.

Daniel (2 March 2004)
- Fixed the libcurl code to use FORMAT_OFF_T for printf() formatting
  curl_off_t types internally.

Daniel (1 March 2004)
- Added CURL_VERSION_LARGEFILE as a feature-bit in the curl_version_info()
  response, that signals if this libcurl supports >2GB files. curl -V now
  outputs 'Largefile' in the Features: field if this is the case. Most systems
  are likely to support this.

- We offer a CURL_FORMAT_OFF_T define in the public header, which can be used
  to printf() curl_off_t variables. We also modified the libcurl sources to
  use this define instead of the previous %Od approach (although I've left the
  O-flag functional in the code). This should also prevent compilers to warn
  on the home-grown option.

- Fixed the resume-check code to test for a working resume at the end of the
  headers and not at the first body-byte.

- CURLOPT_DNS_USE_GLOBAL_CACHE is now considered obsolete. Stop using it. If
  you need a global DNS cache for whatever reason, use the share interface and
  you'll get a global cache that works the way it should work. You can even
  have any number of global caches, all at your command. This is now also
  mentioned in the docs.

- Made the *printf code support the z-flag to enable size_t printf() in a
  manner similar to how glibc allows it. To make printfing of this work on
  platforms with 64bit size_t and 32bit ints. If there even are any! ;-)

- Christopher R. Palmer discovered that if you CURLOPT_FRESH_CONNECT and
  CURLAUTH_NTLM (or CURLAUTH_ANY and libcurl then picked NTLM), libcurl would
  loop without succeeding to authenticate due to the new connection that was
  made for all round-trips in the authentication. Now, the FRESH_CONNECT is
  remade to only matter for the first connection made with curl_easy_perform()
  and all the rest that might follow due to FOLLOWLOCATION or HTTP
  authentication are now ignoring that option.

- Adjusted the QUIT code slightly since it could core-dump.

- Corrected the test suite's FTP server to provide a correct size to the
  'verifiedserver' request.

Daniel (27 February 2004)
- Joe Halpin made the FTP code send QUIT on the control connection before
  disconnecting the TCP connection. This is what good-behaving ftp clients
  should do.

Daniel (26 February 2004)
- David Byron updated several files to make curl build fine on MSVC 6. He
  also added the 'buildconf.bat' that works like the 'buildconf + configure'
  combo does on unixes.

- Gisle Vanem made the memdebug stuff support calloc() as well.

- Tor Arntsen pointed out that testcurl.sh needed to remove the generated
  files in order to have them re-generated in each build.

- Andy Serpa found out that the share interface did not enjoy life when not
  having the lock and unlock callbacks set, even though documented to be
  OK. It still is OK, and now the code won't segfault anymore!

Daniel (25 February 2004)
- Based on a patch by Greg Hewgill I modified how long long is used in the
  mprintf code, as we can use a 64bit type with MSVC that is a long long
  equivalent. This corrects some weird large file behaviors on windows.

- Tor Arntsen helped me work out --enable-debug to work better with different
  versions of the gcc and icc compilers.

- Added CURLOPT_SHARE to the curl_easy_setopt.3 man page.

Daniel (22 February 2004)
- Applied the final pieces of Gisle Vanem's patch that brings a working name
  resolve timeout to the windows versions of curl!

Daniel (21 February 2004)
- David Byron's fix to allow the speed-limit logic work even if you set
  limit-rate. It does work on the expense of the rate limiter.

Daniel (20 February 2004)
- configure --enable-debug with gcc now also tries to detect the icc compiler
  (which somehow gets treated as if it is a gcc) to stop using all the gcc
  options with it, and we also provide -isystem options for each extra -I
  option the configure script has figured out (for OpenSSL, kerberos, zlib,
  Heimdal etc). This of course to prevent warnings on headers we don't have
  control of.

Daniel (19 February 2004)
- Doug Porter made libcurl use the HOME environment variable before the
  getpwuid results when looking for .netrc files.

- If 'configure --enable-debug' is used with gcc, it now checks which gcc
  version it is and uses as picky compiler options as possible for the
  particular version.

- Code that can be used in both the lib and in the curl app is now made to use
  the curlx_ prefix. The first function to be available like this is the
  curlx_strtoll() function. This is made to allow the app to use existing code,
  but without polluting the libcurl API. Further explanations posted here:

    https://curl.haxx.se/mail/lib-2004-02/0215.html

Daniel (18 February 2004)
- Fixed buildconf to not use "which" as AIX and Tru64 have what have been
  referred to as "horribly broken 'which' programs".

- Made sure dns cache timeout set to -1 really means caching forever.

Daniel (17 February 2004)
- Made it possibly to build c-ares with the libcurl memdebug system to better
  track memory.

Daniel (16 February 2004)
- When using ares, we now initialize the ares 'channel' in curl_easy_init()
  and re-use that same handle during the entire curl handle's life-time. It
  improves performance.

- Fixed a problem when displaying verbose for IPv6-enabled libcurls and
  re-used connections. Problem reported and fix verified by Grigory Entin.

- Jeff Lawson fixed the version-check in the SOCKS5 code.

Daniel (15 February 2004)
- Fixed a case where a host cache entry was not flagged in-use properly when a
  cached entry was used.

- Andrés García's patch that checks for winmm in the configure script was
  applied.

Daniel (13 February 2004)
- Ben Greear's SO_BINDTODEVICE patch for the binding of the local end to a
  specific network interface.

- Greg Hewgill found out that the variable holding 'contentlength' wasn't big
  enough to hold a large file!

- Tor Arntsen fixed a 64bit-related problem in date-related code in the ftp
  department, and there was another potential problem in the name resolve code
  too.

Daniel (11 February 2004)
- Removed a few variables that were only set but never used, as some compilers
  warn about that and we do not like compiler warnings!

- Removed the need for symlinks in the tests/data directory if curl is built
  outside of the source directory and the 'make test' is used. This was done
  by providing a "source dir path" to the scripts/servers.

- Now, if the configure script can't find an nroff tool or an option to nroff
  to use to convert man pages with, it will completely switch off the built-in
  manual.

- 'configure --disable-manual' completely disables the built-in manual from
  the curl command tool.

- Andrés García fixed the configure script and a minor source edit, and now
  he has managed to get msys/mingw to run configure and then build!

Daniel (9 February 2004)
- The default HTTP Accept: header was modified to the much simpler
  "Accept: */*".

- P R Schaffner updated the curl-ssl spec file for RPMs.

- Dominick Meglio brought lots of documentation for the share interface's man
  pages that were previously missing.

- Tor Arntsen provided a patch that makes libcurl work-around a bug in the
  AIX5 implementation of getaddrinfo(). This makes the FTP PORT stuff work on
  IPv6-enabled AIX builds.

- Ken Rastatter provided portability fixes for the curlgtk.c example, and now
  it runs on windows with GTK as well!

Daniel (6 February 2004)
- Andrés García made the configure script find gethostbyname() fine when run
  with mingw on windows.

- Modified the ldap code to use proper function pointers all over (instead of
  mixed data and function pointers) to work-around the picky MIPSPro compiler
  warnings.

- A custom Host: header is only considered if the request is not made by
  following a location. After discussions with Tim Baker.

Daniel (5 February 2004)
- The libz part of the configure script now only set the two libz-related
  define HAVE_ZLIB_H and HAVE_LIBZ if both the lib and the header is found.
  If one is missing, none of the defines is set.

- Andrés García fixed the Mingw makefiles.

- Len Krause reported that curl 7.9.X could do uploading from stdin without
  doing chunked encoding, which current curl cannot do even if you disable
  the transfer-encoding chunked header. Now it can again, and test case 98
  verifies this functionality.

- Tor Arntsen fixed a weird getaddrinfo() usage in the FTP code, preventing
  the IPv6-code for PORT work on AIX 5.2. We now also provide (better) error
  messages when bailing out in the that function.

- Tor Arntsen now provides AIX and IRIX (using gcc, xlc and the MIPSPro
  compilers) automated build logs (https://curl.haxx.se/auto/) and we've fixed
  numerous minor quirks to make less warnings appear.

Daniel (4 February 2004)
- Based on a patch by Gilad, we now use the custom timeouts when waiting for a
  server to connect when using FTP PORT. Previously we always waited 10
  seconds, no more no less. We now also changed the default (if no timeout is
  set) to wait 60 seconds for the connect before we fail.

Daniel (3 February 2004)
- Modified to link with c-ares instead of ares.

Daniel (2 February 2004)
- Added a configure test to check for which option the (g)nroff tool wants
  to extract plain text from the man pages. Tor Arntsen told us the AIX
  version of GNU gnroff doesn't support -man!

- Added an undef of accept in memdebug.h to make curl build with --enable-debug
  on AIX 5.2 which seems to have accept defined. Reported by Tor Arntsen.

- curl_version() now includes c-ares version info, and curl_version_info() now
  returns a struct with version SECOND that also includes that info.

- We are now officially using c-ares for asynch name resolves. c-ares is the
  new library, based on the existing ares but with an extended and slightly
  modified API.

- Dirk improved the ares timeout code, and now we also include the ares error
  string when we fail to resolve a name.

- Another tweak to make test case 91 run fine. Now we have another bit on a
  connection that is set true if the connection is marked for 'retry'. That
  makes the connection get closed and re-opened and the HTTP-done code must
  not complain on the fact that no data was received.

- Based on Dirk Manske's patch, I modified the name resolving with ares to
  feature a timeout for really slow lookups. It now defaults to 300 seconds,
  but is now adjusted to the CONNECTTIMEOUT/TIMOUE timeouts if one of them
  is set.

- Fixed the inclusion of ca-bundle.h to really use the one in the build dir
  before the one in the source dir. Domenico Andreoli found out and reported.

- Added test case 97, a simple POST with a custom Content-Type header
  replacing the original application/x-www-form-urlencoded one.

Daniel (30 January 2004)
- Added code that attempts to fix the test 91 failure. As has been figured out
  by Patrick Smith, the error happens because we re-use a connection that the
  server is just about to close and we even manage to send away the request
  without seeing an error. On the first read attempt we get a ECONNRESET.
  Starting now, we attempt to detect this and if so, we retry the request on a
  fresh connection.

- I added test case 510 which is a custom program that does a POST using a
  read callback, with chunked transfer-encoding.

- Adjusted one of the MPE/iX changes as it made test case 504 fail all over.

- Added --socks as a recognized option. It works just like --proxy but sets a
  SOCKS5 proxy to use. SOCKS5 support has been available in libcurl for a
  while, just not provided by the curl tool. This does not currently work for
  IPv6-enabled libcurls.

Daniel (29 January 2004)
- Stadler Stephan pointed out that src/hugehelp.c included config.h without
  checking the define if its present...

- Ken Hirsch provided patches to make curl build fine on the MPE/iX operating
  system.

- Dan Fandrich compiled curl with lots of aggressively pedantic compiler
  options and thus found a few minor errors and did some general cleanups to
  avoid them.

- Dirk Manske fixed a flaw in ares that prevented it to use non-blocking
  sockets properly.

Daniel (28 January 2004)
- Richard Bramante fixed chunked transfer-encoded "uploads" to send a final
  CRLF combo properly.

Daniel (27 January 2004)
- Made the response-headers during a CONNECT request to a proxy get passed on
  as regular headers, so they appear with -i/-I options and similar.

- Based on a patch by Gisle Vanem, I've made the progress meter display
  properly switch to a GB-display when more than 9999MB have been transfered.

Daniel (23 January 2004)
- Gisle Vanem pointed out a curlrc parser problem/crash when an option with a
  required didn't have one and was on the last line of a file.

- More Windows fixes for large files. We now build and link with
  ../lib/strtoofft.c in the app code since Curl_strtoll() is not a provided
  libcurl function... Perhaps we should consider a 'common' dir or similar
  where we put source code used in both the lib and the client. Or perhaps
  we'll just make this function available in the library...

- Vincent Bronner found out the socks5 code crashed when no username was
  set.

- Vincent Bronner spotted a problem with proxy username/password when re-using
  a persistent connection.

- Fixed the progress meter display for files larger than 2^31 bytes. Gisle
  Vanem reported.

Daniel (22 January 2004)
- Gisle Vanem made strtoll() get used when curl is built with the mingw
  compiler.

- Gisle Vanem fixed the compressed help text code to display properly.

- Removed the '#define HttpPost' from the public header file, as curl_httppost
  is the proper name and it has been for quite some time now. Fixes another
  name space pollution.

- Added 'curl_off_t' typedef in the public header file, to be used to provide
  large file sizes to the *_LARGE options. Adjusted the code all over to use
  this variable type instead of 'off_t'. This is an attempt to make the large
  file support work on more platforms. The configure script now checks the
  size of the curl_off_t instead of the plain off_t.

Version 7.11.0 (22 January 2004)

Daniel (21 January 2004)
- Removed the defines in the public header file with TIMECOND_ prefixes. They
  have been obsolete since April 22nd 2002, and if this causes anyone any
  problems now it is very easy to just add CURL_ to the names. This corrects
  this name space pollution.

Daniel (19 January 2004)
- David Byron cleaned up how --trace with no option was treated, and also
  arguments in a config file without a required parameter!

Daniel (16 January 2004)
- Gisle Vanem fixed a few issues where compilers warned about variables
  possibly being used unassigned.

- Minor Interix build problem fixed.

Daniel (15 January 2004)
- Peter Sylvester pointed out some necessary escaping needed in the
  acinclude.m4 file when automake 1.8 or later is used.

Daniel (14 January 2004)
- Vincent Bronner fixed the Curl_resolv() return code. This extends the fix
  Steve Green provided on december 3...

Daniel (13 January 2004)
- Luke Call made the win32 version of the password prompting function support
  backspace.

- Dan Fandrich fixed the hugehelp source file to contain both a compressed and
  an uncompressed version in the distribution, so that more people easier can
  build curl with the compressed version.

- Diego Casorran brought another AmigaOS build patch for native Amiga builds.

- Matt Veenstra updated the Mac OS X framework files.

- Brian R Duffy brought a section to the INSTALL file on how to build a
  SSL-enabled curl using the free Borland C++ compiler. He also updated the
  Borland lib/Makefile.b32.

- I fixed the test case 509 which I broke yesterday. Now the libtest are
  compiled with an include path that points to the library's source dir, so
  that the libtests can include files from the source tree. This was made to
  make it possible to use the USE_SSLEAY define in the library test files.

Daniel (12 January 2004)
- Peter Sylvester brought code that now allows a callback to modified the URL
  even when the multi interface is used, and then libcurl will simulate a
  "follow location" to that new URL. Test 509 was added to test this feature.

- Extended the time we retry servers in the test script, and I also made it
  retry the https and ftps servers before they are considered bad. I believe
  the previous approach could turn problematic on really slow hosts.

Version 7.11.0-pre1 (12 January 2004)

Daniel (11 January 2004)
- Dominick Meglio pointed out FTPS should use default port 990 according to
  IANA.

Daniel (8 January 2004)
- Fixed the SPNEGO configure check to not use -R or other non-portable options
  in the LDFLAGS. Reported by Pierre in bug report #872930.

Daniel (5 January 2004)
- Dan Fandrich provided a fix on our zlib usage.

- David J Meyer's patch that introduce large file support to libcurl was
  applied. New curl_easy_setopt options that accept 'off_t' arguments are:

  INFILESIZE_LARGE
  RESUME_FROM_LARGE
  MAXFILESIZE_LARGE

Daniel (4 January 2004)
- Based on Dominick Meglio's comments, I made our private version of
  gettimeofday() declared static. This would otherwise collide with the same
  function in other libs (like ares for example).

- Added Dominick Meglio's description on how to build libcurl with ares
  on win32.
Daniel (19 December)
- CURLOPT_IPRESOLVE was not possible to set.

- Gisle Vanem updated the djgpp build files.

Daniel (18 December)
- John McGowan reported a redirect-problem that happened if a site used a URL
  like "url.com?var=content" (without a proper slash) and from that address
  redirected the user-agent to an absolute directory.

- David Byron made libcurl build fine with both the .NET and VC6 versions of
  MSVC

Daniel (16 December)
- Updated test 506 since it started to fail after the cache prune change
  yesterday. I also changed it slightly to feature a counter in each debug
  output for easier tracing.

Daniel (15 December)
- Old DNS cache entries are now only pruned after curl is done with a request,
  and not in the actual name resolve call.

- corrected the --enable-ares patch

- Giuseppe Attardi found and fixed a problem within libcurl that re-used
  already freed memory.

Daniel (10 December)
- Gisle Vanem reported that the dict support was broken. I broke it during my
  ftps-changes overhaul. I've now added a 'curlassert' function that can be
  used to verify expressions, to prevent future errors of the same
  kind. They're only present in debug-builds.

- Diego Casorran made curl and libcurl possible to build natively (no more
  need for the ixemul library) on AmigaOS.

- Dominick Meglio made configure --enable-ares support a given path to the
  installed ares lib, instead of always using it in the curl source tree.
  This also fixed the curl-config --libs output.

- Eric S. Raymond patched a very minor man page format error in
  libcurl-errors.3

Daniel (8 December)
- Fixed the flaw that made -lz appear twice on the link command line.

- After correspondence with Gisle Vanem, I changed the 'connection aborted'
  error text when the FTP response reader failed to more specificly identify
  what the problem is.

- Based on a patch from Dominick Meglio, curl-config --feature now outputs
  'AsynchDNS' as a feature if libcurl was built with ares. The feature name
  is the same that 'curl -V' outputs, for simplicity.

Daniel (3 December)
- Marty Kuhrt made the build up-to-date on VMS, and moved most of the VMS-
  specific stuff in the client code to a separate header file.

- Steve Green fixed a return code bug in Curl_resolv(), that made the socks5
  code fail.

- swalkaus at yahoo.com patched libcurl to ignore Content-Length: headers
  when Transfer-Encoding: chunked is used, as mandated by RFC2616.

Daniel (2 December)
- --ftp-pasv was added, which serves the only purpose of overriding a
  previously set --ftpport option. Starting now, --ftp-port is a recognized
  alias for --ftpport for consistency.

- Giuseppe Attardi pointed out that we should use MSG_NOSIGNAL when we use
  send() and recv(). I added checks for the define in the configure script and
  adjusted the code accordingly. If the symbol is present, we won't attempt
  to ignore the SIGPIPE signal.

Daniel (1 December)
- Mathias Axelsson set up a bsdftpd-ssl server for me and I could make curl
  run fine against its FTPS implementation. Now these FTPS-related things
  work:
   o explicit and implicit FTPS
   o active (PORT) and passive (PASV)
   o upload and download
   o verified against bsdftpd-ssl and RaidenFTPD

Daniel (27 November)
- James Clancy made the Borland Makefiles up to date.

- Markus Moeller improved the SPNEGO detection in the configure script.

Daniel (25 November)
- Dave May filed bug report #848371, identifying that if you'd do POST over a
  proxy to a https server, libcurl didn't POST at all, it just made a GET! It
  turned out to be because libcurl wrongly didn't consider the authentication
  "negotiation phase" to be complete yet.

  I added test case 95 to verify my fix for this.

Daniel (24 November)
- Thanks to Mathias Axelsson, I've been able to work on FTPS for libcurl and it
  seems to work somewhat fine now.

  The FTPS stuff is based on RFC2228 and the murray-auth-ftp-ssl draft
  (version 12). There seems to exist quite a few servers that have implemented
  the server side of this.

  We can now use ftps:// URLs to explicitly switch on SSL/TSL for the control
  connection and the data connection (dealing with two SSL connections forced
  me to change a lot of stuff in libcurl).

  Alternatively, and what seems to be the recommended way, we can set the new
  option CURLOPT_FTP_SSL to one of these values:

     CURLFTPSSL_NOPE,   - do not attempt to use SSL
     CURLFTPSSL_TRY     - try using SSL, proceed anyway otherwise
     CURLFTPSSL_CONTROL - SSL for the control connection or fail
     CURLFTPSSL_ALL     - SSL for all communication or fail

  Any failure to set the desired level will make libcurl fail with the error
  code CURLE_FTP_SSL_FAILED. This new option makes a "normal" ftp:// transfer
  attempt to be made securely.

  I've been able to login and get files (passively) from Mathias' server using
  both ftps:// and CURLOPT_FTP_SSL. (I've made 'curl' understand the --ftp-ssl
  option that sets CURLFTPSSL_TRY.)

- Gaz Iqbal fixed a range string memory leak.

- Gisle Vanem fixed the Windows builds.

- Added the new FTPSSL defines in curl/curl.h

Daniel (20 November)
- Josh Kapell filed bug report #845247 as he found an endless loop when
  getting a 407 back from a proxy when no user+password was given. Added test
  case 94 to verify the fix.

Daniel (19 November)
- Kevin Roth fixed a progress-bar problem on Windows.

- While working with Nicolas Croiset's bug report #843739, I noticed two minor
  problems related to ftp partial downloads: if a partial transfer is
  detected, we must close the connection as we cannot know in what state it is
  anymore. This looks like a ProFTPD bug:
  https://curl.haxx.se/mail/lib-2003-11/0079.html

Daniel (17 November)
- Maciej W. Rozycki made the configure script use a cache variable for the
  writable argv test. This way, the default can be overridden better (for
  cross-compiles etc)

Daniel (15 November)
- Mathias Axelsson found out libcurl sometimes freed the server certificate
  twice, leading to crashes!

Daniel (14 November)
- Siddhartha Prakash Jain found a case with a bad resolve that we didn't
  properly bail out from, when using ares.

Daniel (13 November)
- Default Content-Type for parts in multipart formposts has changed to
  "application/octet-stream".  This seems more appropriate, and I believe
  mozilla and the likes do this. In the same area: .html files now get
  text/html as Content-Type. (Pointed out in bug report #839806)

- Gisle Vanem corrected the --progress-bar output by doing a flush of the
  output, which apparently makes it look better on at least windows, but
  possibly other platforms too.

- Peter Sylvester identified a problem in the connect code, which made the
  multi interface on a IPv6-enabled Solaris box do bad. Test case 504 to be
  specific. I've spent some time to clean-up the Curl_connecthost() function
  now to use less duplicated code for the two different sections: IPv6 and
  IPv4.

Daniel (11 November)
- Added CURLOPT_NETRC_FILE. Use this to tell libcurl which file to use instead
  of trying to find a .netrc in the current user's home directory. The
  existing .netrc file finder is somewhat naive and is far from perfect on
  several platforms that aren't unix-style. If this option isn't set when
  CURLOPT_NETRC is set, the previous approach will still be used.

  The current .netrc check code now also support longer than 256 bytes path
  names.

Daniel (10 November)
- Kang-Jin Lee pointed out that the generated ca-bundle.h file shouldn't be
  written in the source dir if a different build dir is used.

- After Sébastien Willemijns' bug report, we now check the separators properly
  in the 229-reply servers respond on a EPSV command and bail out better if
  the reply string is not RFC2428-compliant.

Daniel (7 November)
- Based on Gisle Vanem's patch, I made curl try harder to get the home
  directory of the current user, in order to find the default .curlrc file.
  We're also considering moving out the HOME-dir code from libcurl, and
  instead have the app pass in the path to the .netrc file (which is the only
  logic left in libcurl that uses the HOME dir). Then curl can use the home
  dir for that purpose too.

- Ralph Mitchell's updated testcurl.sh to the script to take an existing
  directory name and build/run/test curl in there instead of trying to update
  from CVS. Using this approach, the script can now be used to test daily
  tarballs etc.

- Gisle Vanem added a "resource file" to the Windows DLL builds, to contain
  information such as version number, library name, copyright info etc.

Daniel (6 November)
- curl checks if the existing libcurl supports things like --ntlm, --negotiate
  and --krb4 and returns error if not.

- I added three new global defines in the curl/curl.h header:
  LIBCURL_VERSION_MAJOR, LIBCURL_VERSION_MINOR and LIBCURL_VERSION_PATCH. They
  are the three numbers in the library's version number, separated for easier
  usage. 'maketgz' was updated accordingly to generate these numbers properly
  when building release-archives.

- Uninitialized variable fix, reported by both Marty Kuhrt and Benjamin
  Gerard.

- Matt Veenstra provided build files to build libcurl as a "framework" under
  Mac OS X. See the lib/libcurl.framework.make for details.

- Removed the defines of TRUE and FALSE from the curl/curl.h header file.
  They're not in our name space so we should not fiddle with them.

Daniel (5 November)
- Replaced the man page to HTML converter program with a new one: roffit.
  Makes nicer web pages.

Daniel (4 November)
- Troels Walsted Hansen fixed the MSVC makefiles to let them build curl fine
  on Windows.

- Kevin Roth corrected the cygwin package generator and spell-fixed the
  comment in the ca-bundle.h file.

Version 7.10.8 (1 November 2003)

Daniel (31 October)
- Assume that MDTM on an FTP server returns the timestamp using the UTC time
  zone. This changes the time CURLINFO_FILETIME returns for a given file over
  FTP, and will change existing uses of CURLOPT_TIMECONDITION. It will make
  the functionality more similar to how the HTTP one is already working.

- Command line options that take numerical parameters (such as -y, -Y, -C etc)
  now report error and exit if the parameter isn't truly a number greater than
  or equal to zero. This helps users to notice bad usage earlier. Before, when
  a user forgot or missed to add a numerical parameter to an option, the
  command line parser would simply "eat" the following option and it would
  cause great confusion.

Daniel (30 October)
- David Hull made libcurl deal with NOBODY and HEADER for file:// the same way
  it already does for FTP: it provides HTTP-looking headers that provide info
  only about the file, without doing the actual transfer. The curl tool then
  lets --head do this.

Daniel (29 October)
- runtests.pl now checks for and use valgrind if present. It will redirect the
  valgrind results in log/valgrind[num] but it currently doesn't scan that
  file for any errors or anything, that is still only made manually.

- David Hull made the file: URL parser also accept the somewhat sloppy file
  syntax: file:/path. I added test case 203 to verify this.

Daniel (28 October)
- Dan C tracked down yet another weird behavior in the glibc gethostbyname_r()
  function for some specific versions (reported on 2.2.5 and 2.1.1), and
  provided a fix. On Linux machines with these glibc versions, non-IPv6
  builds of libcurl would often fail to resolve perfectly resolvable host
  names.

Daniel (26 October)
- James Bursa found out that curl_msnprintf() could write the trailing
  zero-byte outside its given buffer size. This could happen if you generated
  a very long error message as then libcurl would overwrite the ERRORBUFFER
  with one byte. Using a non-existing very long local file:// name is one case
  that could make this occur.

Daniel (24 October)
- David Hull filed bug report #829827. It identified a problem with -C - if
  the full file already was downloaded and thus the server responded with a
  416. libcurl would then wrongly use the Content-Length: header and expect
  that size to get transfer, causing a "hang" until the server closed the
  connection and then an error 18 ("still N bytes data left of the transfer").

  Now we don't return any error at all, but I think libcurl should perhaps
  return some kind of info since the requested range was out of the size of
  the document.

- Based on David Hull's fix in bug report #804599, we now check for solaris and
  gcc in configure and set the -mimpure-text link flag for linking the lib
  better.

- I've introduced a -t option to the runtests.pl script. With that option set,
  the script runs special "memory torture" tests. For each test command line
  in that section, the script first runs the command line and counts the total
  amount of allocations made. It then runs the exact same command line again,
  forcing allocation number N to fail. It will try every N from 1 to the total
  number of amounts made. For every invoke, it checks that no memory was
  leaked as that would indicate a bad cleanup somewhere in the code.

  This is just beginning to work, and I've already made some corrections in
  libcurl code. When this code works somewhat fine, I'll make sure 'make test'
  in the root dir will run these tests as well.

Daniel (23 October)
- Georg Horn fixed how the CA verification is made. Verifications can now be
  made while at the same time the result of it can be ignored. This also
  affects the curl tool as -k can now be used together with --cacert or
  --capath.

Daniel (22 October)
- Gisle Vanem found out --disable-eprt didn't work and patched it.

- Test case 91 was modified and could now repeat the problem Kevin Roth has
  reported, and the bug was fixed.

- Dylan Ellicott added vc-libcurl-ssl-dll as a target to the root makefile
  to build a static libcurl that links with a shared OpenSSL using MSVC.

Daniel (21 October)
- Andrés García updated the mingw32 makefiles.

Version 7.10.8-pre5 (21 October 2003)

Daniel (19 October)
- Georg Horn made libcurl output more info on SSL failures when receiving
  data.

Version 7.10.8-pre4 (18 October 2003)

Daniel (17 October)
- Dominick Meglio implemented CURLOPT_MAXFILESIZE and --max-filesize.

- Made libcurl show verbose info about what auth type and user name that is
  being sent in its HTTP request-headers.

Daniel (16 October)
- Removed support for CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA. libcurl
  no longer prompt for passwords under any circumstances. Password prompting
  was instead moved to curl, which now prompts for password if -u or -U lack
  it. This solves the problem Kevin Roth reported when curl prompted for
  password twice when doing NTLM authentication.

- I rewrote the SSL subjectAltName check to avoid having to rely on OpenLDAP-
  licensed derivate code.

Daniel (15 October)
- Avoid doing getsockopt() on Windows to verify connects. It seems that this
  hogs Windows machines when libcurl is being used multi-threaded (with > ~50
  threads). Andrew Fuller helped us verify and test this.

Daniel (14 October)
- Kimmo Kinnunen fixed a crash with duphandle() when CURLDEBUG is set.

- Gisle Vanem made libcurl build and work with IPv6 on Windows.

Daniel (13 October)
- Giuseppe Attardi reported yet another segfault with ares and the multi
  interface. Me fixed.

- Domenico Andreoli removed the extra LDFLAGS assignment in lib/Makefile.am
  that was reported about in the debian bug report #212086.

  Domenico also fixed two makefiles where we used 'gnroff' instead of the more
  portable $(NROFF).

Daniel (12 October)
- Dirk Manske made the share locking around DNS lookups slightly different to
  allow the share system's DNS lookups to run somewhat more
  independent/faster.

Daniel (9 October)
- Lachlan O'Dea fixed a resume problem: "If I set CURLOPT_RESUME_FROM, perform
  an HTTP download, then reset CURLOPT_RESUME_FROM to 0, the next download
  still has a Range header with a garbage value." bug report #820502

- Dominick Meglio made the inet_pton.c file build fine using MSVC.

- The 'sws' test suite web server now #include setup.h from the lib directory.
  This makes it more portable easier.

Version 7.10.8-pre3 (8 October 2003)

Daniel (8 October)
- Frank Ticheler provided a patch that fixes how libcurl connects to multiple
  addresses, if one of them fails (IPv4 code).

Daniel (7 October)
- Neil Dunbar provided a patch that now makes libcurl check SSL
  subjectAltNames when matching certs. This is apparently detailed in RFC2818
  as the right thing to do. I had to add configure checks for inet_pton() and
  our own (strictly speaking, code from BIND written by Paul Vixie) provided
  code for the function for platforms that miss it.

- HTTP POST using the read callback didn't work, as Florian Schoppmann
  reported.

Daniel (5 October)
- Shared provided a few fixes to make libcurl build on BeOS
  out-of-the-box. New code for BeOS-style non-blocking sockets, provided by
  Shard and Jeremy Friesner. Modified the autoconf check for non-blocking
  sockets to check for this kind too.

Daniel (4 October)
- Vincent Bronner pointed out that if you set CURLOPT_COOKIE for a transfer
  and then set it to NULL in a subsequent one, the previous cookie was still
  sent off!

- Jon Turner fixed a problem libcurl had when it failed on an FTP transfer due
  to a bad path, it would cause the next transfer to use a bad path as well.

- Siddhartha Prakash Jain provided a patch with a fix for libcurl with ares,
  when working on IP-only names as we then could return "wait" status when the
  name in fact already was resolved. I edited the patch slightly to not expose
  asynch details to non-ares aware source code.

Daniel (3 October)
- Neil Spring posted the debian bug report #213180, and pointed out that using
  the name 'access' in a function prototype is not very wise as some compilers
  complain.

- Peter Sylvester provided his and Jean-Paul Merlin's curlx.c example source
  code that shows how they use ssl and callbacks.

Daniel (2 October)
- James MacMillan's patch makes curl build on QNX 6.2.x.

Daniel (26 September)
- My daughter was born!

Daniel (23 September)
- Added support for -4/--ipv4 and -6/--ipv6 to force names to resolve to that
  particular IP version. They only work for IPv6-enabled libcurls.

- curl -V now outputs 'SPNEGO' as a feature in case libcurl was built to
  support that.

Version 7.10.8-pre2 (22 September 2003)

Daniel (22 September)
- Giuseppe Attardi found a segfault in libcurl when using the multi interface
  with ares and doing repeated operations against a non-resolving host name.

Daniel (19 September)
- Added the CURLOPT_IPRESOLVE option, that allows an application to select
  what kind of IP addresses he wants to use when resolving host names. This
  is only interesting when using host names that resolve addresses using more
  than one version of IP.

- Applied Markus Moeller's patch that introduces SPNEGO support if libcurl
  is built with the FBopenssl libraries. curl_version_info() now returns
  info on SPNEGO availability. The patch also made the GSSAPI stuff work fine
  with the MIT GSS-library (the Heimdal one still works too).

Daniel (16 September)
- Doing PUT with --digest failed, as reported in bug report #805853.

- Using --anyauth that picked NTLM, and then a redirect closed the connection
  and took curl to a second NTLM page made curl fail. Bug report #806328
  identified the problem, test case 90 was added to verify the fix.

Daniel (14 September)
- codemastr brought a patch for ares to make the Windows portions of it work
  properly on NT4. I uploaded a new diff and updated the docs on where to get
  it etc.

- Jeff Pohlmeyer tracked down a very hard-to-find bug where we removed a
  cached DNS entry even though it may be in use, which caused "random" memory
  to get overwritten and thus "random" crashes.

Daniel (12 September)
- Based on a bug report by David Kimdon, I made the runtests.pl script clear
  all possible proxy environment variables before the tests are run.

- By default, easy handles within a multi handle now share DNS cache.

- Tim Bartley brought a patch that makes the GSSNEGOTIATE option work for
  Microsoft's "Negotiate" authentication as well.

Daniel (11 September)
- A zero-length proxy string confused FTP transfers.

- Bjorn Reese found a case with an uninitialized pointer, only present when
  built for ares.

Version 7.10.8-pre1 (8 September 2003)

Daniel (7 September)
- Jurij Smakov found out that the non-OpenSSL MD5 code was not working on
  Alpha (or ia64). Only the OpenSSL-version did. I made a fix I think corrects
  the problem.

Daniel (5 September)
- Kevin Fisk reported that configure --enable-thread didn't work. I fixed.

- De-macrofied the lib/hash.c source code somewhat.

Daniel (4 September)
- CURLINFO_HTTPAUTH_AVAIL and CURLINFO_PROXYAUTH_AVAIL added, Based on Joerg
  Mueller-Tolk's patch,

Early (4 September)
- Added CURLOPT_FTP_RESPONSE_TIMEOUT - allows user to set strict timeout
  requirements on the FTP server's ability to respond to individual commands
  without placing global requirements on transfer or connect time.  Files
  affected:
    - include/curl/curl.h
        Added option CURLOPT_FTP_RESPONSE_TIMEOUT
    - lib/ftp.c
        Added branch inside Curl_GetFTPResponse to check for
        data->set.ftp_response_timeout
    - lib/url.c
        Modified Curl_setopt to recognize CURLOPT_FTP_RESPONSE_TIMEOUT
    - lib/urldata.h
        Added ftp_response_timeout to struct UserDefined

Daniel (3 September)
- Peter Pentchev found and fixed two problems in the test suite's web server
  code, that made it segfault at times.

- Jörg Mueller-Tolk improved the proxy user+password handling, especially
  when providing a blank password.

Daniel (2 September)
- Fix for making CONNECT to proxies do the correct magic to allow NTLM, Digest
  and similar to work.

Daniel (1 September)
- Henrik Storner made libcurl work fine with OpenLDAP 2.1.22 (current).

- Jeff Pohlmeyer added a proper error message for non-resolving hosts when
  using ares for lookups.

Daniel (25 August)
- John McGowan reported that curl -k still failed if the HTTPS server's CN
  field wasn't obtainable. This was due to the CURLOPT_SSL_VERIFYHOST being
  set to 1, and libcurl failed if the CN was missing. Starting now, having it
  set to 1 will simply output a warning if no CN could be obtained (as having
  a mismatch is OK).

Daniel (21 August)
- Vincent Sanders provided a fix for name resolving when linked with uClibc.

Daniel (20 August)
- Gerd v. Egidy provided a patch that makes libcurl store the FTP response
  code from ftp servers. Using curl_easy_getinfo() with CURLINFO_HTTP_CODE
  returns that data. The option is therefore now also known as
  CURLINFO_RESPONSE_CODE.

- Antoine Calando found a segfault when doing multi-part/formpost using
  the multi interface.

- Antoine Calando pointed out that curl_multi_info_read() didn't set the
  msgs_in_queue to 0 properly when returning NULL.

Daniel (19 August)
- I made curl support multiple -T options, as well as -T "{file1,file2}"
  style globbing. One -T for each URL is supported.

- Jeff Pohlmeyer found a segfault when using ares-enabled libcurl and the
  multi interface when trying a non-existing host name.

- Made the libcurl printf code support long longs if available.

- Loren Kirkby pointed out that we did not clean up all SSL-allocated memory
  in curl_global_cleanup().

Daniel (17 August)
- Setting CURLOPT_WRITEFUNCTION or CURLOPT_READFUNCTION to NULL will now make
  them get the internal defaults restored. Previously this could cause a
  segfault. We should aim at having all pointer-related options get restored
  to default/safe values when set to NULL.

Version 7.10.7 (15 August 2003)

Daniel (14 August)
- I modified the memdebug system to return failure on memory allocation
  functions after a set amount of successful ones. This enables us to test
  out-of-memory situations in a controlled manner and we can make sure that
  curl/libcurl behaves good in those.

  This made me find and fix several spots where we did not cleanup properly
  when bailing out due to errors (low memory).

- Corrected test case 74. Made using -o with bad #[num] codes complain and
  bail out. Made #[num] support numbers larger than 9 as well. Added test
  case 86 for a proper range globbing test as well.

Version 7.10.7-pre4 (12 August 2003)

Daniel (12 August)
- curl_version_info() now returns a flag if libcurl was built with asynch DNS
  support, and this is now also displayed with 'curl -V'.

- Added a few new man pages to the docs/libcurl dir: curl_share_init,
  curl_share_setopt, curl_share_cleanup, libcurl-easy and libcurl-share.

Daniel (11 August)
- Mike Cherepov made the local binding code work for Windows, which makes
  the option CURLOPT_INTERFACE work on Windows as well.

- Vincent Sanders updated the fopen.c example code a lot.

- --proxy-ntlm is now supported by the curl tool. It forces the proxy
  authentication to be made using NTLM. It does not yet work for HTTPS over
  proxies (or other proxy-tunneling options). Test case 81 and 82 do some
  simple initial ntlm testing.

- Found and fixed a minor memory leak on re-used connections with
  proxy-authentication.

- I removed -@ and -Z as valid short options. They were very rarely used (@
  wasn't even documented).

- Serge Semashko introduced CURLOPT_PROXYAUTH, and make it work when set to
  CURLAUTH_NTLM and/or CURLAUTH_BASIC. The PROXAUTH is similar to HTTPAUTH,
  but is for the proxy connection only, and HTTPAUTH is for the remote host.

- Fixed loading of cookies with blank contents from a cookie jar. Also made the
  cookie functions inform on added and skipped cookies (for cookie debugging).

Version 7.10.7-pre3 (8 August 2003)

Daniel (8 August)
- Applied David Byron's fix for file:// URLs with drive letters included.

- I added the --ftp-create-dirs to the client code, which activates Early's
  CURLOPT_FTP_CREATE_MISSING_DIRS option, and wrote test case 147 to verify
  it. Added the option to the curl.1 man page too. Added the option to the
  curl_easy_setopt.3 man page too.

Daniel (7 August)
- Test case 60 failed on ia64 and AMD Opteron. Fixed now.

- Fixed a printf problem that resulted in urlglobbing bugs (bug #203827 in the
  debian bug tracker). Added test case 74 to verify the fix and to discover if
  this breaks in the future.

- "make distcheck" works again.

Version 7.10.7-pre2 (6 August 2003)

Daniel (5 August)
- Duncan Wilcox helped me verify that the latest incarnation of my ares patch
  builds fine on Mac OS X (see the new lib/README.ares) file for all details.

- Salvatore Sorrentino filed bug report #783116 and Early Ehlinger posted a
  bug report to the libcurl list, both identifying a problem with FTP
  persistent connections and how the dir hierarchy was not properly reset
  between files.

- David Byron's thoughts on a fixed Makefile in tests/ were applied.

- Jan Sundin reported a case where curl ignored a cookie that browsers don't,
  which turned up to be due to the number of dots in the 'domain'. I've now
  made curl follow the the original netscape cookie spec less strict on that
  part.

Daniel (4 August)
- Dirk Manske added cookie support for the experimental, hidden and still
  undocumented share feature!

- Mark Fletcher provided an excellent bug report that identified a problem
  with FOLLOWLOCATION and chunked transfer-encoding, as libcurl would not
  properly ignore the body contents of 3XX response that included the
  Location: header.

Early (6 August)
- Added option CURLOPT_FTP_CREATE_MISSING_DIRS
    This option will force the target file's path to be created if it
    does not already exist on the remote system.

  Files affected:
    - include/curl/curl.h
        Added option CURLOPT_FTP_CREATE_MISSING_DIRS
    - lib/ftp.c
        Added function ftp_mkd, which issues a MKD command
        Added function ftp_force_cwd, which attempts a CWD,
          and does a MKD and retries the CWD if the original CWD
          fails
        Modified ftp_perform() to call its change directory function
          through a pointer.  The pointer points to ftp_cwd by default,
          and is modified to point to ftp_force_cwd IFF
          data->set.ftp_create_missing_dirs is not 0.
    - lib/url.c
        Modified Curl_setopt to recognize CURLOPT_FTP_CREATE_MISSING_DIRS
    - lib/urldata.h
        Added ftp_create_missing_dirs to struct UserDefined

- Minor Bugfix for CURLOPT_TIMECONDITION with FTP - if the file was not
  present to do the time comparison, it would fail.
  Files affected:
    - lib/ftp.c
        In ftp_perform(), the call to ftp_getfiletime() used to be followed
        by
	  if (result)
            return result;
        And then by the code that actually did the time comparison.
        The code that did the comparison handled the case where the filetime
        was not available (as indicated by info.filetime < 0 or set.timevalue
        < 0), so I replaced the if (result) return result with a switch(result)
        that allows CURLE_FTP_COULDNT_RETR_FILE to fall through to the
        normal time comparison.

Daniel (3 August)
- When proxy authentication is used in a CONNECT request (as used for all SSL
  connects and otherwise enforced tunnel-thru-proxy requests), the same
  authentication header is also wrongly sent to the remote host.

  This is a rather significant info leak. I've fixed it now and mailed a patch
  and warning to the mailing lists.

Daniel (1 August)
- David Byron provided a patch to make 7.10.6 build correctly with the
  compressed hugehelp.c source file.

Version 7.10.7-pre1 (31 July 2003)

Daniel (30 July)
- Jörg Müller-Tolk updated the VC makefile.

- Daniel Noguerol made the ftp code output "Accept-Ranges: bytes" in similar
  style like other faked HTTP headers when NOBODY and HEADER are used. I
  updated two corresponding test cases too.

- Marty Kuhrt pointed out a compilation problem on VMS due to my having
  changed a type from long to time_t, and I'm now changing it back to work
  more portably...

  He also indicated that distributing the src/hugehelp.c in a compressed state
  like I accidentally did may not be the smartest move... I've now fixed the
  distribute procedure to automatically generate an uncompressed version when I
  make release archives.

Daniel (29 July)
- Gisle Vanem brought changes to the mkhelp script for the generation of the
  compressed help text on some platforms.

Version 7.10.6 (28 July 2003)

Daniel (28 July)
- François Pons brought a patch that once again made curl deal with ftp and
  "double slash" as indicating the root directory. In the RFC1738-fix of April
  30, that ability was removed (since it is not the "right" way). So, starting
  now we can list the root dir of an ftp server both these ways:

    curl ftp://server.com/%2f  as well as
    curl ftp://server.com//

Daniel (24 July)
- Henry Bland pointed out that we included sys/resource.h without good reason
  in several source files. Without it included, QNX builds better...

- Andrés García updated the mingw makefiles.

Daniel (23 July)
- Tracy Boehrer experienced DNS cache problems and did some nice debugging
  and tracking which made it easy for me to correct the problem and Tracy
  could verify that it did cure the problem! When re-using a connection we
  now make sure we don't re-use the 'connect_addr' struct.

- Daniel Kouril corrected the GSS-Negotiate code.

- Juan F. Codagnone provided fixes to allow curl to build fine on Windows
  again.

Daniel (22 July)
- Edited the curl/curl.h include file to build on Windows properly.

Daniel (21 July)
- Moved the proxy credentials from the SessionHandle struct to the connectdata
  struct, to make multiple proxy connections with differerent user names work.

- Adjusted the NTLM code to support proxy functionality.

- Made the krb4 stuff compile with the user+password fields moved.

Version 7.10.6-pre4 (21 July 2003)

Daniel (20 July)
- David Gardner pointed out in bug report 770755 that using the FTP command
  CWD with a blank argument is a bad idea and I made libcurl skip empty path
  segments starting now.

Daniel (18 July)
- Cris pointed out that my fix on July 16th didn't work fully. His pointing
  out this (and his patch) also made me realize that we have a very similar
  bug in the FTP connection re-use code. We must store a separate user and
  password field for each connection we keep (at least for FTP and HTTP+NTLM
  connections, so I made us do this unconditionally).

- Since NTLM authenticates connections instead of single requests, I had to
  re-arrange how we store the NTLM data and I had to improve the test suite to
  finally work properly with persistency to make the NTLM tests run fine
  again. This also forced me to have to update lots of HTTP test cases.

Daniel (16 July)
- Cris Bailiff's bug report 768275 pointed out that using Basic auth with
  wrong user+password caused an endless loop. Fixed now. He also found out that
  we didn't properly authenticate connections with NTLM. Fixed too.

- Dan Winship provided fixes for the NTLM code.

Daniel (5 July)
- Doug Kaufman provided additional fixes for the DOS port.

Daniel (4 July)
- Rick Richardson pointed out that using setvbuf() to achieve non-buffering
  on output is no-good for SCO Xenix and other unixes. We switched over to
  using plain fflush() instead.

- Dan Grayson pointed out that we set the CURL_CA_BUNDLE variable wrongly in
  the configure script, and I had to change some build stuff to make the new
  way work.

- Peter Sylvester's patch was applied that introduces the following:

   CURLOPT_SSL_CTX_FUNCTION to set a callback that gets called with the
   OpenSSL's ssl_ctx pointer passed in and allow a callback to act on it. If
   anything but CURLE_OK is returned, that will also be returned by libcurl
   all the way back. If this function changes the CURLOPT_URL, libcurl will
   detect this and instead go use the new URL.

   CURLOPT_SSL_CTX_DATA is a pointer you set to get passed to the callback set
   with CURLOPT_SSL_CTX_FUNCTION.

Daniel (1 July)
- David Byron provided a patch that allows a client to quit the test suite's
  HTTP server.

- Gisle Vanem found and patched a lib handle leak in the ldap code.

Daniel (25 June)
- More NTLM-improvements. Less code. Smaller packets back and forth.

Daniel (23 June)
- Eric Glass provided us with a better doc on NTLM details, and I added more
  comments and clarified the current code more. Using the new knowledge, we
  should be able to make the NTLM stuff work even better.
  Eric's original URL: http://davenport.sourceforge.net/ntlm.html
  Version stored and provided at curl site: https://curl.haxx.se/rfc/ntlm.html

- Fixed the minor compile problems pre3 had if built without GSSAPI and/or
  SSL.

Version 7.10.6-pre3 (19 June 2003)

Daniel (19 June)
- Made curl use curl_free() on memory returned by curl_getenv(), as this
  should theoreticly make it possibly to build and run curl and libcurl with
  different memory allocation schemes with no problems.

Daniel (18 June)
- Improved the mkhelp.pl a bit further to make a nicer hugehelp text and to
  include a better comment in the top for the gzip compressed version.

Daniel (17 June)
- CURLOPT_HTTPAUTH is now a bitmask, in which you set which authentication
  type(s) you want to use. If more than one is set, libcurl will use one of
  the selected one and the one it considers is more secure. Test case 67 and
  68 (for NTLM) were fixed and we've reduced a round-trip for specific --ntlm
  fetches, and test case 69 and 70 were added for testing authentication
  "picking". --anyauth is the new command line tool option, and I also added
  --basic for completeness (that's the default type).

- Fixed the runtests.pl script to use the info provided by the new curl -V
  output.

- --enable-debug now sets the CURLDEBUG define instead of MALLOCDEBUG, as it
  is meant to be a generic debug conditional.

- curl_version_info() can now return CURL_VERSION_DEBUG as a feature bit, to
  indicate that the library was built with CURLDEBUG set.

- Ralph Mitchell found out that some web applications very badly uses white
  spaces in Location: redirects, and apparently IE is a browser (the only
  one?) that supports this abomination. Based on Ralph's patch, I added code
  that now attempts to replace white spaces with the proper "%20" or "+".
  Test case 40 and 42 were added to verify my changes.

- curl -V now also outputs a list of features the available library offers (if
  any).

- The curl_version() string now includes "GSS" if libcurl is built with GSSAPI
  support.

- David Orrell reported that libcurl still crashed when sending HUGE requests
  over HTTPS... I fixed.

Version 7.10.6-pre2 (16 June 2003)

Daniel (16 June)
- curl_version_info() now returns bitmasked information weather NTLM and
  GSSNEGOTIATE are supported, since it is doomed to vary on different
  installations.

- I remade the HTTP Digest code to use the MD5-code provided by OpenSSL if
  that is present, and only use our own MD5-code if it isn't.

Daniel (13 June)
- More NTLM help, fixes and patches from Cris Bailiff.

- Marty Kuhrt brought include fixes for making VMS builds warning-free.

Daniel (12 June)
- NTLM authentication works somewhat against the test servers provided by
  Mathias Axelsson and Cris Bailiff. Use by setting CURLOPT_HTTPAUTH to
  CURLAUTH_NTLM to libcurl, or --ntlm for the curl tool. Test case 67 and 68
  were added for this. NTLM-support requires OpenSSL.

- Dan Fandrich provided a patch, that granted that gzip and libz are available
  at build-time, compresses the hugehelp text in the curl command line and
  uncompresses it at request. Saves some ~60K in the final output executable.

Daniel (11 June)
- Long day of fighting the NTLM demons.

Daniel (10 June)
- Modified how to set auth type to libcurl. Now use CURLOPT_HTTPAUTH instead,
  and pick method. Supported ones currently are:
  CURLAUTH_BASIC     - default selection
  CURLAUTH_DIGEST    - formerly CURLOPT_HTTPDIGEST
  CURLAUTH_GSSNEGOTIATE

- Daniel Kouril added HTTP GSS-Negotiate authentication support, as defined in
  the IETF draft draft-brezak-spnego-http-04.txt. In use already by various
  Microsoft web applications. --negotiate is the new family member. To take
  advantage of this, you need one of these packages:

  o Heimdal Kerberos5               http://www.pdc.kth.se/heimdal/heimdal.html
  o GSSAPI from Globus                   http://www.globus.org/
  o GSSAPI libraries from MIT Kerberos5  http://web.mit.edu/kerberos/www/

- A missing ending bracket (']') while doing URL globbing could lead to a
  segfault. While fixing this, I also introduced better error reporting in the
  globbing code. (All this is application code outside libcurl.)

Daniel (6 June)
- David Orrell found out that sending a huge GET request over HTTPS could
  make libcurl fail and return an error code.

Daniel (2 June)
- Richard Bramante found out that "Content-Length: 0" was not properly used by
  libcurl if the response-headers indicated that the connection would be
  closed.

- David Byron's patch was applied, that makes the --progress-bar take the
  local size into account when doing resumed downloads.

- Feedback from Serge Semashko made me change the error message returned when
  CURLE_HTTP_RETURNED_ERROR is returned.

- Anonymous in bug report #745122 pointed out that we should really be using
  SSL_CTX_set_options(... SSL_OP_ALL) to work around flaws in existing SSL
  implementations.

Daniel (27 May)
- Andreas Ley and Rich Gray helped me point out that no version of HP-UX has
  the sys/select.h header file so including it unconditionally in curl/multi.h
  is not a good thing. Now we check for HPUX and avoid using that header on
  such systems.

- Rudy Koento experienced problems with curl's recent habit of POSTing data in
  two separate send() calls, first the headers and then the data. I've now
  made a fix that for static and known content that is less than 100K in size,
  everything is now sent in one single system call again. This is also better
  for network performance reasons.

- I modified the main makefile to not build the test suite and a few other
  unnecessary things by default. Now, the test suite is built when 'make test'
  is run.  This reduces build time for those who don't care for the test
  suite, and it also reduces confusion for people using platforms where the
  test suite build fails!

Daniel (26 May)
- Chris Lewis pointed out a flaw in the #ifdefs in curl/multi.h for Windows,
  which is now corrected.

- Jis Joy found another flaw in the SOCK5 code, as libcurl treated the socks5
  proxy a little too much like as if it was a http proxy.

Daniel (23 May)
- Ricardo Cadime found a socket leak when listing directories without
  contents. Test cases 144 and 145 were added to verify the fix.

- Rudy Koento found yet another problem when a HTTP server returns only a
  single-line of contents without any headers at all. libcurl then failed to
  count the data, thus returning error 52 "no contents". Test case 66 was
  added to verify that we now do right.

Version 7.10.6-pre1 (23 May 2003)

Daniel (23 May)
- Jis in bug report #741841, fixed a bug in the SOCKS5 proxy-using code.

Daniel (22 May)
- David Remahl set up a test-server for me providing Digest authentication,
  and I wrote the first working code that support it. The test suite was
  modified slightly as well to work better for it and --digest was added to
  the command line options (and CURLOPT_HTTPDIGEST to the library)...  RFC2617
  has all the gory details.

Daniel (21 May)
- David Balazic pointed out that curl_unescape() didn't check that %-codes
  were correctly followed by two hexadecimal digits when it unescape strings.
  Now, we do the check and only %XX codes are unescaped if the X letters are
  hexadecimals.

- Gisle Vanem made curl build with djgpp on DOS.

- Gisle Vanem improved the mkhelp.pl script to make a nicer manual that is
  shown with curl -M.

Daniel (20 May)
- Gisle Vanem provided a fix that makes libcurl more conservative, not
  expecting h_aliases of the hostent struct to always be non-NULL.

Daniel (19 May)
- As requested by Martin Michlmayr in Debian bug report #193630, libcurl now
  supports user name and password in the proxy environment variables. Added
  test case 63 to verify this.

Version 7.10.5 (19 May 2003)

Daniel (15 May)
- Changed the order for the in_addr_t testing, as 'unsigned long' seems to be
  a very common type inet_addr() returns.

Daniel (14 May)
- George Comninos provided a fix that calls the progress meter when waiting
  for FTP command responses take >1 second. It'll make applications more
  "responsive" even when dealing with very slow ftp servers.

Daniel (12 May)
- George Comninos pointed out that libcurl uploads had two quirks:
   o when using FTP PORT command, it used blocking sockets!
   o it could loop a long time without doing progress meter updates
  Both items are fixed now.

Daniel (9 May)
- Dan Fandrich changed CURLOPT_ENCODING to select all supported encodings if
  set to "".  This frees the application from having to know which encodings
  the library supports.

- Dan Fandrich pointed out we had three unnecessary files in CVS that is
  generated with libtoolize, so they're now removed and libtoolize is invoked
  accordingly in the buildconf script.

- Avery Fay found out that the CURLOPT_INTERFACE way of first checking if the
  given name is a network interface gave a real performance penalty on Linux,
  so now we more appropriately first check if it is an IP number and if so
  we don't check for a network interface with that name.

- CURLOPT_FTP_USE_EPRT added. Set this to FALSE to disable libcurl's attempts
  to use EPRT and LPRT before the traditional PORT command. The command line
  tool sets this option with '--disable-eprt'.

Version 7.10.5-pre2 (6 May 2003)

Daniel (6 May)
- Kevin Delafield reported another case where we didn't correctly check for
  EAGAIN but only EWOULDBLOCK, which caused badness on HPUX.

Daniel (4 May)
- Ben Greear noticed that the check for 'writable argv' exited the configure
  script when run for cross-compiling, which wasn't nice. Now it'll default to
  no and output a warning about the fact that it was not checked for.

Daniel (2 May)
- Added test case 62 and fixed some more on the cookie sending with a custom
  Host: header set.

Daniel (1 May)
- Andy Cedilnik fixed a few compiler warnings.

- Made the "SSL read error: 5" error message more verbose, by adding code that
  queries the OpenSSL library to fill in the error buffer.

Daniel (30 Apr)
- Added sys/select.h include in the curl/multi.h file, after having been
  reminded about this by Rich Gray.

- I made each test set its own server requirements, thus abandoning the
  previous system where the test number implied what server(s) to use for a
  specific test.

- David Balazic made curl more RFC1738-compliant for FTP URLs, by fixing so
  that libcurl now uses one CWD command for each path part. A bunch of test
  cases were fixed to work accordingly.

- Cookie fixes:

  A. Save domains in jars like Mozilla does. It means all domains set in
     Set-Cookie: headers are dot-prefixed.
  B. Save and use the 'tailmatch' field in the Mozilla/Netscape cookie jars
     (the second column).
  C. Reject cookies using illegal domains in the Set-Cookie: line. Concerns
     both domains with too few dots or domains that are outside the currently
     operating server host's domain.
  D. Set the path part by default to the one used in the request, if none was
     set in the Set-Cookie line.

  To make item C really good, I also made libcurl notice custom Host: headers
  and extract the host name set in there and use that as the host name for the
  site we're getting the cookies from. This allows user to specify a site's
  IP-address, but still be able to receive and send its cookies properly if
  you provide a valid Host: name for the site.

Daniel (29 Apr)
- Peter Kovacs provided a patch that makes the CURLINFO_CONNECT_TIME work fine
  when using the multi interface (too).

Version 7.10.5-pre1 (23 Apr 2003)

Daniel (23 Apr)
- Upgraded to libtool 1.5.

Daniel (22 Apr)
- Peter Sylvester pointed out that curl_easy_setopt() will always (wrongly)
  return CURLE_OK no matter what happens.

- Dan Fandrich fixed some gzip decompression bugs and flaws.

Daniel (16 Apr)
- Fixed minor typo in man page, reported in the Debian bug tracker.

Daniel (15 Apr)
- Fixed some FTP tests in the test suite that failed on my Solaris host, due
  to the config.h not being included before the system headers. When done that
  way, it did get a mixed sense of if big files are supported or not and then
  stat() and fstat() (as used in test case 505) got confused and failed to
  return a proper file size.

- Formposting a file using a .html suffix is now properly set to Content-Type:    text/html.

Daniel (14 Apr)
- Fixed the SSL error handling to return proper SSL error messages again, they
  broke in 7.10.4. I also attempt to track down CA cert problems and then
  return the CURLE_SSL_CACERT error code.

- The curl tool now intercepts the CURLE_SSL_CACERT error code and displays
  a fairly big and explanatory error message. Kevin Roth helped me out with
  the wording.

Daniel (11 Apr)
- Nic Hines provided a second patch for gzip decompression, and fixed a bug
  when deflate or gzip contents were downloaded using chunked encoding.

- Dan Fandrich made libcurl support automatic decompression of gzip contents
  (as an addition to the previous deflate support).

- I made the CWD command during FTP session consider all 2xy codes to be OK
  responses.

Daniel (10 Apr)
- Vlad Krupin fixed a URL parsing issue. URLs that were not using a slash
  after the host name, but still had "?" and parameters appended, as in
  "http://hostname.com?foobar=moo", were not properly parsed by libcurl.

Daniel (9 Apr)
- Made CURLOPT_TIMECONDITION work for FTP transfers, using the same syntax as
  for HTTP. This then made -z work for ftp transfers too. Added test case 139
  and 140 for verifying this.

- Getting the file date of an ftp file used the wrong time zone when
  displayed. It is supposedly always GMT. Added test case 141 for this.

- Made the test suite's FTP server support MDTM.

- The default DEBUGFUNCTION, as enabled with CURLOPT_VERBOSE now outputs
  CURLINFO_HEADER_IN data as well. The most notable effect from this is that
  using curl -v, you get to see the incoming "headers" as well. This is
  perhaps most useful when doing ftp.

Daniel (8 Apr)
- James Bursa fixed a flaw in the Content-Type extraction code, which missed
  the first letter if no space followed the colon.

- Magnus Nilsson pointed out that share.c was missing in the MSVC project
  file.

Daniel (6 Apr)
- Ryan Weaver provided a patch that makes the CA cert bundle not get installed
  anymore when 'configure --without-ssl' has been used.

Daniel (4 Apr)
- Martijn Broenland found another cases where a server application didn't
  like the boundary string used by curl when doing a multi-part/formpost. We
  modified the boundary string to look like the one IE uses, as this is
  probably gonna make curl work with more applications.

Daniel (3 Apr)
- Kevin Roth reported that a bunch of tests fails on cygwin. One set fails
  when using perl 5.8 (and they run fine with perl 5.6), and another set
  failed because of an artifact in the test suite's FTP server that I
  corrected. It turned out the FTP server code was still having a file opened
  while the main test script removed it and invoked the HTTP server that
  attempted to create the same file name of the file the FTP server kept open.
  This operation works fine on unix, but not on cygwin.

Version 7.10.4 (2 Apr 2003)

Daniel (1 Apr)
- Added test case 505 to exercise FTP upload with rename done with libcurl,
  and for that I had to extend the test suite's FTP server to deal with the
  RNFR and RNTO commands.

Daniel (31 Mar)
- Even more SSL config check modifications after Richard's testing.

Version 7.10.4-pre6 (31 Mar 2003)

Daniel (31 Mar)
- More fixes for the SSL session ID cache checks when SSL configs are changed
  between connections. Based on tests and talks with Richard Bramante.

- Guillaume Cottenceau provided a patch that added CURLOPT_UNRESTRICTED_AUTH.
  When enabled, it will prevent libcurl from limiting to which host it sends
  user+password to when following locations. By default, libcurl only sends
  name and password to the original host used in the first URL, but with this
  option set it will send the auth info to all hosts it follows location
  headers to. The new tool command line option for this is named
  "--location-trusted".

- Frankie Fong reported a problem with libcurl if you re-used an easy handle
  with a proxy, and you first made a https:// connection to a host and then
  switched to a http:// one to the same host. libcurl would then wrongly re-use
  the same connection for it and fail to get the second URL properly

Daniel (29 Mar)
- Dan Shearer's fix that makes curl complain if invoked with nothing but "curl
  -O" was applied.

Daniel (26 Mar)
- Bryan Kemp was friendly enough to lend me an account on his Redhat 9 box and
  I could fix the configure problems on redhat 8.1 and 9 in no time thanks to
  this. Thanks a bunch Bryan!

Daniel (25 Mar)
- Renamed configure.in to configure.ac

Version 7.10.4-pre5 (25 Mar 2003)

Daniel (25 Mar)
- Richard Bramante provided a fix for a handle re-use problem seen when you
  change options on an SSL-enabled connection between requests. Previously,
  changing peer verification or host verification and similar things was not
  taken into account when a connection were checked for re-use and thus
  enabling stricter check between requests on a re-used connection made no
  difference and the connection would thus be used erroneously.

Daniel (24 Mar)
- Götz Babin-Ebell pointed out that the ca-bundle.crt file contained a
  certificate from Trustcenter that was a demo certificate only that was never
  intended to be part of a CA bundle.

Daniel (21 Mar)
- Life is a mystery. Within a time period of 17 hours, Tim Pope and Michael
  Churchill filed one bug report each, both identifying problems with a second
  transfer when doing persistent transfers re-using a connection. Tim's one is
  #706624, labeled "Multiple uploads per handle fail" and Michael's #707003
  "Does not send Authorization: header when reusing connection". I could track
  both down to the same piece of logic and it turned out libcurl was not using
  new settings properly when re-using an existing connection. This concerned
  both uploading and downloading and involved exactly those pieces these two
  reports identified. This code has been this faulty since the day I
  introduced persistent connection support in libcurl, more than 2 years ago.

Daniel (20 Mar 2003)
- Five year anniversary. Today five years ago, the first ever curl release saw
  the light of day.

Daniel (17 Mar)
- Andy Cedilnik corrected flaws in some libcurl example-usage sources.

Daniel (16 Mar)
- Juan F. Codagnone reported that the fix from March 2nd was incomplete.

- Added code to the configure.in to check for select() argument types. I've
  not made any code use the results just yet though.

Daniel (15 Mar)
- Gisle Vanem provided two patches to build better on Windows.

- Adjusted the test suite code to better make sure that the server(s) required
  for a specific test is properly started before the test case is attempted.
  Many tests now run a lot faster than before.

Daniel (14 Mar)
- Another configure.in adjustment made the configure detect functions properly
  on HPUX now.

Daniel (13 Mar)
- Philippe Raoult fixed pre4-compile quirks for FreeBSD.

Version 7.10.4-pre4 (13 Mar 2003)

Daniel (13 Mar)
- Added a backup-check for functions that aren't found by AC_CHECK_FUNCS()
  as I believe some checks on HPUX need this. At least some of the info given
  to us by Rick Jones seemed to indicate this.

Daniel (12 Mar)
- Thomas Tonino found out that if you used the curl tool to do PUT operations
  as in 'curl www.foo.com/dir/ -T file' and the file name included for example
  space or other characters that don't belong in URLs, curl did not properly
  URL encode them before using them in the URL.

- Added an option to configure called --enable-libgcc that simply adds -lgcc
  to the LIBS variable, as this seems to be a common problem.

- I modified the configure.in file, so that the headers are now checked in an
  order of "viality". We must also make sure to use the "default headers"
  parameter to AC_CHECK_HEADERS() so that headers are checked with the proper
  prerequisites included (i.e all the major and generally important header
  files are included there by default). This might be what we need for various
  Sun, HP, AIX and Tru64 systems to behave good again on the header check
  front.

- Rick Jones pointed out a few compiler warnings on HP-UX that I addressed.

- I made the configure --help output nicer by using AC_HELP_STRING() a lot
  more.

Daniel (11 Mar)
- Christophe Demory fixed the socket sending code to work better on HP-UX
  when sending data to a socket that would block. It then returns EAGAIN, not
  EWOULDBLOCK.

- Richard Gorton improved the seeding function for systems without a good
  and reliable random source.

- Richard Gorton fixed a few warnings that popped up when you built curl
  using the Sun compiler on a 64bit SPARC platform.

- Martin C. Martin fixed a case where a connect failure using the multi
  interface didn't produce a human readable error string.

Daniel (10 Mar)
- Reverted ltmain.sh back to libtool 1.4.2 status again, as the 1.4.3 version
  broke the build on numerous platforms. It seems that libtool 1.4.3 puts some
  requirements on what versions of the other tools (autoconf + automake) that
  I am not familiar with and thus I couldn't fulfill at this point.

  Yes, this is more than mildly frustrating.

Daniel (7 Mar)
- Run libtoolize version 1.4.3.

Version 7.10.4-pre3 (4 Mar 2003)

Daniel (3 Mar)
- Added share.obj to the VC6 and Borland libcurl makefiles.

- Troels Walsted Hansen found and investigated a problem with libcurl on AIX,
  presumably only on 4.3 or later. gethostbyname_r() is not returning data
  that is possible to "keep" and cache the way libcurl does. But instead these
  versions of AIX uses a gethostbyname() that works thread-safely we can
  instead use the ordinary gethostbyname() and our pack_hostent() approach to
  achieve what we want. The configure script now attempts to detect AIX 4.3 or
  later to adjust for this.

Daniel (2 Mar)
- Juan F. Codagnone found a problem introduced in 7.10.3 when you first did a
  POST and then back to a GET using the same easy handle.

Daniel (28 Feb)
- Removed the strequal and strnequal defines from curl/curl.h header. They
  were never meant for the public header anyway. Philippe Raoult brought it
  up.

- James Bursa fixed the RISC OS build.

Daniel (27 Feb)
- Avery Fay pointed out the very misleading curl_multi_info_read man page, and
  I updated it to become more accurate.

- Salvatore Sorrentino found a problem with FTP downloading that turned out to
  be his FTP server returning size zero (0 bytes) when SIZE was used on a file
  while being in BINARY mode. We now make a second check for the actual size
  by scanning the RETR reply anyway, even if the SIZE command returned 0.

Daniel (26 Feb)
- Kyle Sallee reported a case where he would do a transfer that didn't update
  the progress meter properly. It turned out to be a case where libcurl would
  loop a little too eagerly in the transfer loop, which isn't really good for
  the APIs, especially not the multi API.

Version 7.10.4-pre2 (24 Feb 2003)

Daniel (24 Feb)
- Kjetil Jacobsen found out that setting CURLOPT_MAXCONNECTS to a value higher
  than 5 could cause a segfault.

- I believe I fixed the 'Expect: 100-continue' behavior that has been broken
  for a while (I think since my change dated Dec 10 2002). When this header is
  used, libcurl should wait for a HTTP 100 (or timeout) before sending the
  post/put data.

Daniel (14 Feb)
- Matthew Clarke provided some info what to modify to make curl build
  flawlessly on AIX 3.2.5.

- Martin C. Martin found and fixed a problem in the multi interface when
  running on Windows and trying to connect to a port without a listener.

Daniel (13 Feb)
- Christopher R. Palmer fixed Curl_base64_encode() to deal with zeroes in the
  data to encode.

Daniel (4 Feb)
- Jean-Philippe added the first code that enables the 'share' system. This
  should now enable sharing of DNS data between two curl easy handles.

- Incorporated Nico Baggus' fixes to again compile flawlessly on VMS.

- James Bursa corrected a bad comment in the public include file curl/multi.h

- Peter Forret reported one of those error:00000000 cases in libcurl again
  when connecting to a HTTPS site, and this time I did discover some oddities
  in how curl reports SSL errors back. It could miss showing the actual error.

Version 7.10.4-pre1 (3 Feb 2003)

Daniel (3 Feb)
- Removed things in the docs saying capath doesn't work on Windows, as Julian
  Noble told us it works fine.

Daniel (31 Jan)
- Kevin Roth fixed the zlib build stuff in the Mingw32 makefile.

Daniel (30 Jan)
- Kevin Roth found out that curl on Windows always checked for the CA cert
  bundle using the environment variable and the path scan, even though
  -k/--insecure was used.

- Hamish Mackenzie pointed out that curl only did strict host name verifying
  if capath or cainfo was used. Now it'll always do it unless -k / --insecure
  is used!

- Pavel Cenek pointed out that the Content-Type extraction was done wrongly
  as the full string was not fetched. Added test case 57 to verify that curl
  does it right now.

Daniel (29 Jan)
- Jamie Wilkinson provided a patch that now makes curl attempt to clear out
  "sensitive" command line arguments so that they don't appear in ps outputs
  (only on platforms that allow writing to argv[]).

- John McGowan found out that the DEBUGFUNCTION could be called with bad
  arguments and thus cause the --trace outputs to go wrong.

- Removed all the emacs local variables from all files. Mats Lidell provided
  the new sample.emacs file (for a sample of what to include in your .emacs)
  and the curl-style.el that sets a better c-style for editing curl sources.

- Dave Halbakken found a problem with FTP downloads that could accidently
  return CURLE_PARTIAL_FILE when curl_easy_perform() was called with NOBODY
  set TRUE.

Daniel (27 Jan)
- The fopen.c example was flawed as Nick Humfrey noticed, and I fixed it to
  work again.

Daniel (24 Jan)
- Bertrand Demiddelaer found and fixed a memory leak (the content-type string)
  when following locations.

Daniel (22 Jan 2003)
- Ian Wilkes and Legoff Vincent both independently provided fixes for making
  curl/multi.h work properly when compiled with a C++ compiler.

Daniel (20 Jan 2003)
- Fixed 'buildconf' to check version number of the required tools before
  they're actually used.

- Wrote 'testcurl.sh', a script targeted for automatic and distributed curl
  tests on various platforms.

- David Thiel pointed out that the .netrc file was not being dealt with
  properly anymore. I broke this in the password prompting "fix".

- Markus F.X.J. Oberhumer patched libcurl to allocate the scratch buffer only
  on demand and thus we save 32KB in each curl handle that don't use that
  buffer. This need appeared when some people started using thousands of
  simultaneous curl handles... :-)

Daniel (16 Jan 2003)
- Markus Oberhumer fixed curl-config --cflags when the includedir was not
  /usr/include.

- Markus Oberhumer fixed CURLINFO_PRIVATE to properly return NULL if it was
  set to NULL!

Version 7.10.3 (14 Jan 2003)

Daniel (10 Jan 2003)
- Steve Oliphant pointed out that test case 105 did not work anymore and this
  was due to a missing fix for the password prompting.

Version 7.10.3-pre6 (10 Jan 2003)

Daniel (9 Jan 2003)
- Bryan Kemp pointed out that curl -u could not provide a blank password
  without prompting the user. It can now. -u username: makes the password
  empty, while -u username makes curl prompt the user for a password.

- Kjetil Jacobsen found a remaining connect problem in the multi interface on
  ipv4 systems (Linux only?), that I fixed and Kjetil verified that it fixed
  his problems.

- memanalyze.pl now reads a file name from the command line, and no longer
  takes the data on stdin as before.

Version 7.10.3-pre5 (9 Jan 2003)

Daniel (9 Jan 2003)
- Fixed tests/memanalyze.pl to work with file names that contain colons (as on
  Windows).

- Kjetil Jacobsen quickly pointed out that lib/share.h was missing...

Version 7.10.3-pre4 (9 Jan 2003)

Daniel (9 Jan 2003)
- Updated lib/share.c quite a bit to match the design document at
  https://curl.haxx.se/dev/sharing.txt a lot more.

  I'll try to update the document soonish. share.c is still not actually used
  by libcurl, but the API is slowly getting there and we can start
  implementing code that takes advantage of this system.

Daniel (8 Jan 2003)
- Updated share stuff in curl/curl.h, including data types, structs and
  function prototypes. The corresponding files in lib/ were also modified
  of course to remain compilable. Based on input from Jean-Philippe and also
  to make it more in line with the design document.

- Jean-Philippe Barrette-LaPierre patched a very trivial memory leak in
  curl_escape() that would happen when realloc() returns NULL...

- Matthew Blain provided feedback to make the --create-dirs stuff build
  properly on Windows.

- Fixed the #include in tests/libtest/first.c as Legoff Vincent pointed out.

Daniel (7 Jan 2003)
- Philippe Raoult provided a patch that now makes libcurl properly support
  wildcard checks for certificate names.

- Simon Liu added CURLOPT_HTTP200ALIASES, to let an application set other
  strings recognized as "HTTP 200" to allow http-like protocols to get
  downloaded fine by curl.

- Now using autoconf 2.57 and automake 1.7.2

- Doing "curl -I ftp://domain/non-existing-file" still outputed a date!
  Wayne Haigh reported.

- The error message is now written properly with a newline in the --trace
  file.

Daniel (6 Jan 2003)
- Sterling Hughes fixed a possible bug: previously, if you called
  curl_easy_perform and then set the global dns cache, the global cache
  wouldn't be used. Pointed out by Jean-Philippe Barrette-LaPierre.

- Matthew Blain's fixed the VC6 libcurl makefile to include better debug data
  on debug builds.
Daniel (27 Dec 2002)
- Philippe Raoult reported a bug with HTTPS connections which I evidently
  added in my 19 dec fix. I corrected it.

Daniel (20 Dec)
- Idea from the Debian latest patch: use AM_MAINTAINER_MODE in the configure
  script to make the default makefile less confusing "to the casual
  installer".

Version 7.10.3-pre3 (20 Dec)

Daniel (19 Dec)
- Matthew Blain patched the Curl_base64_decode() function.

- Evan Jordan reported in bug report #653022 that the SSL_read() usage was
  wrong, and it certainly was. It could lead to curl using too much CPU due to
  a stupid loop.

Daniel (18 Dec)
- As suggested by Margus Freudenthal, CURLE_HTTP_NOT_FOUND was renamed to
  CURLE_HTTP_RETURNED_ERROR since it is returned on any >= 400 code when
  CURLOPT_FAILONERROR is set.

Daniel (17 Dec)
- Bug reported #651464, reported by Christopher Palmer, provided an example
  source code using the multi interface that hang when trying to connect to a
  proxy on a localhost port where no proxy was listening. This bug was not
  repeatable on libcurls that were IPv6-enabled.

Daniel (16 Dec)
- Christopher Palmer also noticed what Vojtech Janota already was
  experiencing: The attempted name resolve fix for glibc 2.2.93 caused libcurl
  to crash when used on some older glibc versions. The problem is of course
  the silliness of the 2.2.93. I committed a fix that hopefully should make
  the binary run fine on either one of the versions, even though the solution
  is not as nice as I'd like it to be.

Daniel (13 Dec)
- Bug report #651460 by Christopher R. Palmer showed that when using libcurl
  to for example go over a proxy on localhost, it would attempt to connect
  through the proxy TWICE.

  I added test case 503 with which I managed to repeat this problem and I
  fixed the code to not re-attempt any connects (which also made it a nicer
  fix for the #650941 bug mentioned below).

  The sws server was extended to deal with CONNECT in order to make test
  case 503 do good.

- Evan Jordan posted bug report #650989 about a memory leak in the public key
  retrieving code. He provided a suggested fix and I merely applied it!

- Bug report #650941, posted by Christopher R. Palmer identified a problem
  with the multi interface and getting file:// URLs. This was now fixed and
  test case 502 was added to verify this.

Daniel (12 Dec)
- Test case 500 and 501 are the first ever libcurl test cases that run.

- Made "configure --enable-debug" cut off all -O* options to the compiler

- Finally fixed the test suite's ftp server so that test case 402 doesn't
  cause the following test case to fail anymore!

Daniel (11 Dec)
- CURL_MAX_WRITE_SIZE is now decreased to 16KB since it makes the Windows
  version perform uploads much faster!!! RBramante did lots of research on
  this topic.

- Fixed the #include in curl/curl.h to include the other files outside the
  extern "C" scope.

Daniel (10 Dec)
- Moved around and added more logic:

  First, POST data is never sent as part of the request headers in the http.c
  code. It is always sent the "normal" read callback then send() way. This now
  enables a plain HTTP POST to be sent chunked if we want to. This also
  reduces the risk of having very big POSTs causing problems.

  Further, sending off the initial HTTP request is not done using a loop
  anymore. If it wasn't all sent off in the first send(), the rest of the
  request is sent off in the normal transfer select() loop. This makes several
  things possible, but mainly it makes libcurl block less when used from the
  multi interface and it also reduces the risk of problems with issuing very
  large requests.

Daniel (9 Dec)
- Moved the read callback pointer and data within the structs to a more
  suitable place. This in preparation for a better HTTP-request sending code
  without (a silly) loop.

- The Dodds fix seems not to work.

- Vojtech Janota tests proved that the resolve fix from oct 21st is not good
  enough since obviously older glibcs might return EAGAIN without this meaning
  that the buffer was too small.

- [the other day] Made libcurl loop on recv() and send() now until done, and
  then get back to select(). Previously it went back to select() more often
  which really was a slight overhead. This was due to the reported performance
  problems on HTTP PUT on Windows. I couldn't see any notable difference on
  Linux...

Version 7.10.3-pre2 (4 Dec 2002)

Daniel (4 Dec 2002)
- Lots of work with Malcolm Dodds made me add a temporary code fix that now
  shortens the timeout waiting for the 226 or 250 line after a completed
  FTP transfer.

  If no data is received within 60 seconds, this is taken as a sign of a dead
  control connection and we bail out.

Daniel (3 Dec 2002)
- Ralph's bug report #644841 identified a problem in which curl returned a
  timeout error code when in fact the problem was not a timeout. The proper
  error should now be propagated better when they're detected in the FTP
  response reading function.

- Updated the Borland Makefiles.

Daniel (2 Dec 2002)
- Nicolas Berloquin provided a patch that introduced --create-dirs to the
  command line tool. When used in combination with -o, it lets curl create
  [non-existing] directories used in -o, suitably used with #-combinations
  such as:

     curl "www.images.com/{flowers,cities,parks,mountains}/pic_[1-100].jpg \
       -o "dir_#1/pic#2.jpg" --create-dirs

Version 7.10.3-pre1

Daniel (28 Nov 2002)
- I visited Lars Nordgren and had a go with his problem, which lead me to
  implement this fix. If libcurl detects the added custom header
  "Transfer-Encoding: chunked", it will now enable a chunked transfer.

  Also, chunked transfer didn't quite work before but seems to do so now.

- Kjetil Jacobsen pointed out that ./configure --disable-ipv6 --without-zlib
  didn't work on any platform...

Daniel (26 Nov 2002)
- Fixed a bad addrinfo free in the hostip.c code, hardly exposed anywhere

- Dan Becker found and fixed a minor memory leak on persistent connnections
  using CURLOPT_USERPWD.

Daniel (22 Nov 2002)
- Based on Ralph Mitchell's excellent analysis I found a bug in the test suite
  web server (sws) which now lets test case 306 run fine even in combination
  with the other test cases.

- Juan Ignacio Hervás found a crash in the verbose connect message that is
  used on persistent connections. This bug was added in 7.10.2 due to the
  rearranged name resolve code.

Daniel (20 Nov 2002)
- Kjetil Jacobsen provided a patch that introduces:

   CURLOPT_PRIVATE stores a private pointer in the curl handle.

   CURLINFO_PRIVATE retrieves the private pointer from the curl handle.

- Karol Pietrzak pointed out how curl-config --cflags didn't output a good
  include dir so I've removed that for now.

Version 7.10.2 (18 Nov 2002)

Daniel (11 Nov 2002)
- Dave Halbakken added curl_version_info to lib/libcurl.def to make libcurl
  properly build with MSVC on Windows.

Daniel (8 Nov 2002)
- Doing HTTP PUT without a specified file size now makes libcurl use
  Transfer-Encoding: chunked.

Daniel (7 Nov 2002)
- Bug report #634625 identified how curl returned timeout immediately when
  CURLOPT_CONNECTTIMEOUT was used and provided a fix.

Version 7.10.2-pre4 (6 Nov 2002)

Daniel (5 Nov 2002)
- Lehel Bernadt found out and fixed. libcurl sent error message to the debug
  output when it stored the error message.

- Avery Fay found some problems with the DNS cache (when the cache time was
  set to 0 we got a memory leak, but when the leak was fixed he got a crash
  when he used the CURLOPT_INTERFACE with that) that had me do some real
  restructuring so that we now have a reference counter in the dns cache
  entries to prevent an entry to get flushed while still actually in use.

  I also detected that we previously didn't update the time stamp when we
  extracted an entry from the cache so that must've been a reason for some
  very weird dns cache bugs.

Version 7.10.2-pre3

Daniel (31 Oct 2002)
- Downgraded automake to 1.6.3 in an attempt to fix cygwin problems. (It
  turned out this didn't help though.)

- Disable the DNS cache (by setting the timeout to 0) made libcurl leak
  memory. Avery Fay brought the example code that proved this.

Version 7.10.2-pre2

Daniel (28 Oct 2002)
- Upgraded to autoconf 2.54 and automake 1.7 on the release-build host.

- Kevin Roth made the command line tool check for a CURL_CA_BUNDLE environment
  variable (if --cacert isn't used) and if not set, the Windows version will
  check for a file named "curl-ca-bundle.crt" in the current directory or the
  directory where curl is located. That file is then used as CA root cert
  bundle.

- Avery Fay pointed out that curl's configure scrip didn't get right if you
  used autoconf newer than 2.52. This was due to some badly quoted code.

Version 7.10.2-pre1

Daniel (23 Oct 2002)
- Emiliano Ida confirmed that we now build properly with the Borland C++
  compiler too. We needed yet another fix for the ISO cpp check in the curl.h
  header file.

- Yet another fix was needed to get the HTTP download without headers to work.
  This time it was needed if the first "believed header" was read all in the
  first read. Test 306 has not run properly since the 11th october fix.

Daniel (21 Oct 2002)
- Zvi Har'El pointed out a problem with curl's name resolving on Redhat 8
  machines (running IPv6 disabled). Mats Lidell let me use an account on his
  machine and I could verify that gethostbyname_r() has been changed to return
  EAGAIN instead of ERANGE when the given buffer size is too small. This is
  glibc 2.2.93.

- Albert Chin helped me get the -no-undefined option corrected in
  lib/Makefile.am since Cygwin builds want it there while Solaris builds don't
  want it present. Kevin Roth helped me try it out on cygwin.

- Nikita Schmidt provided a bug fix for a FOLLOWLOCATION bug introduced when
  the ../ support got in (7.10.1).

Daniel (18 Oct 2002)
- Fabrizio Ammollo pointed out a remaining problem with FOLLOWLOCATION in
  the multi interface.

Daniel (17 Oct 2002)
- Richard Cooper's experimenting proved that -j (CURLOPT_COOKIESESSION) didn't
  work quite as supposed. You needed to set it *before* you use
  CURLOPT_COOKIEFILE, and we dont' want that kind of dependencies.

Daniel (15 Oct 2002)
- Andrés García provided corrections for erratas in four libcurl man pages.

Daniel (13 Oct 2002)
- Starting now, we generate and include PDF versions of all the docs in the
  release archives.

Daniel (12 Oct 2002)
- Trying to connect to a host on a bad port number caused the multi interface
  to never return failure and it appeared to keep on trying forever (it just
  didn't do anything).

Daniel (11 Oct 2002)
- Downloading HTTP without headers didn't work 100%, some of the initial data
  got written twice. Kevin Roth reported.

- Kevin Roth found out the "config file" parser in the client code could
  segfault, like if DOS newlines were used.

Version 7.10.1 (11 Oct 2002)

Daniel (10 Oct 2002)
- Jeff Lawson fixed a few problems with connection re-use that remained when
  you set CURLOPT_PROXY to "".

Daniel (9 Oct 2002)
- Craig Davison found a terrible flaw and Cris Bailiff helped out in the
  search. Getting HTTP data from servers when the headers are split up in
  multiple reads, could cause junk data to get inserted among the saved
  headers. This only concerns HTTP(S) headers.

Daniel (8 Oct 2002)
- Vincent Penquerc'h gave us the good suggestion that when the ERRRORBUFFER
  is set internally, the error text is sent to the debug function as well.

- I fixed the telnet code to timeout properly as the option tells it to. On
  non-windows platforms.

Daniel (7 Oct 2002)
- John Crow pointed out that libcurl-the-guide wasn't included in the release
  tarball!

- Kevin Roth pointed out that make install didn't do right if build outside
  the source tree (ca-bundle wise).

- FOLLOWLOCATION bugfix for the multi interface

Daniel (4 Oct 2002)
- Kevin Roth got problems with his cygwin build with -no-undefined was not
  present in lib/Makefile.am so I put it back in there again. The poor one who
  needs to remove it again must write a configure script to detect that need.

- Ralph Mitchell pointed out that curl was a bit naive and didn't deal with ./
  or ../ stuff in the string passed back in a Location: header when following
  locations.

- Albert Chin helped me to work out a better configure.in check for zlib, and
  both --without-zlib and -with-zlib seem to work rather well right now.

- Zvi Har'El improvied the OpenSSL ENGINE check in the configure script to
  become more accurate.

Daniel (1 Oct 2002)
- Detlef Schmier pointed out the lack of a --without-libz option to configure,
  so I added one.

Version 7.10 (1 Oct 2002)

Daniel (30 Sep 2002)
- Modified the curl_version_info() proto and returned struct once again, and
  updated the man page accordingly.

- Cris Bailiff found out that the pre-releases crashed on name lookups on
  names such as "a:" or "baz:" (on Linux versions not being IPv6-enabled) due
  to some weird return codes from gethostbyname_r(). I'll blame the complete
  lack of docs in that department. Cris provided a fix, which I modified only
  slightly.

Daniel (27 Sep 2002)
- After a suggestion from Christian Kurz to Debian curl package maintainer
  Domenico Andreoli, I made it possible to override the proxy environment
  variables better. Now, by setting -x "" you can explicitly tell libcurl to
  not use a proxy, no matter whan the environment variables say.

Version 7.10-pre4

Daniel (26 Sep 2002)
- Extended curl_version_info() more and wrote a man page for it.

Daniel (25 Sep 2002)
- libcurl could leak memory when downloading multiple files using http ranges,
  reported and fixed by Jean-Luc Guevel.

- Walter J. Mack provided code and docs for the new curl_free() function that
  shall be used to free memory that is allocated by libcurl and returned back
  to the application, as curl_escape() and curl_unescape() do.

- Yarram Sunil pointed out a flaw in the multi interface where a failed
  connection didn't close down properly and thus a second transfer using the
  same handle failed.

- Andrés García fixed a flaw that made (among other things) dict-fetches
  return a random value.

Daniel (24 Sep 2002)
- Wez Furlong brought his initial patch that introduced curl_version_info().
  We might need to tweak it somewhat before release.

Daniel (20 Sep 2002)
- Craig Markwardt fixed another Tru64 IP resolve problem.

Daniel (19 Sep 2002)
- Dolbneff A.V and Spiridonoff A.V made the file:// code work with resumes
  in the same style other code does.

- Ilguiz Latypov fixed a flaw in the client code when fetching multiple URLs
  and -C - was used. The first file's resume position was then accidentally
  reused on all the other files too.

Daniel (18 Sep 2002)
- The curl_easy_setopt.3 man page was greatly modified and the options have
  now been grouped in logical groups so that it should be somewhat easier to
  read it and find things you search for.

Daniel (13 Sep 2002)
- Kevin Roth pinpointed a scary flaw in libcurl, when the HTTP server doesn't
  send any headers back, only raw content. Right, that is a violation of the
  standard but still happens at times and we need to deal with it. Test case
  306 was added to verify that we do right now.

Version 7.10-pre3

Daniel (11 Sep 2002)
- Lukasz Czekierda found out that curl didn't send a correct HTTP Host: header
  when you specified the URL with an IPv6 IP-address.

Daniel (4 Sep 2002)
- Sven Neuhaus made --silent being acknowledged even when multiple URLs
  were used. It used to output "[1/2]: http://host/a.html.de --> a.html.d" etc
  even when told to shut up.

Daniel (3 Sep 2002)
- Updated all source code headers to use MIT-license references only, and
  point to the COPYING file and the https://curl.haxx.se/docs/copyright.html
  URL. I've cut out all references to MPL that I could find.

- Corected the makefiles to not always use -lz when linking

Version 7.10-pre2

Daniel (2 Sep 2002)
- James Gallagher added Content-Encoding support to libcurl so now curl and
  libcurl-using apps can request compressed contents using the 'deflate'
  method. See the special file lib/README.encoding for details.

  curl --compressed is now used to request compressed contents.

  curl-config --feature will include 'libz' if this feature was around when
  the library was built.

Daniel (30 Aug 2002)
- Applied an anonymous SOCKS5-proxy patch. Not properly working in all
  situations though, as all getaddrinfo()-using libcurls will fail on this.
  This is because of the somewhat naive way the current code tries to extract
  the IP address of the proxy.

- Fixed up the SSL cert fixes from the other day even more after more inputs
  from Cris. Added three new SSL error codes to make the
  CURLE_SSL_CONNECT_ERROR slightly less overloaded.

Daniel (27 Aug 2002)
- After lots of talk with Tom Zerucha, Nick Gimbrone and Cris Bailiff I
  decided to talk the bold path and I now made libcurl do CA certificate
  verification by default. Thus library users need to explicitly turn this off
  if you want to connect to sites without proper checking. We also install a
  CA cert bundle on 'make install' now.

  The curl tool now requires the -k/--insecure option in order to allow
  connections and operations on SSL sites that aren't properly verified with
  -cafile or --capath.

  curl-config --ca displays the built-in path to the CA cert bundle.

Daniel (26 Aug 2002)
- Andrew Francis cleaned up some code that now compiles fine without the need
  for ugly MSVC pragmas.

- Keith MacDonald found a minor bug in src/main.c that made it close stdin
  instead of the actual file handle. It shouldn't have resulted in much
  trouble as most operating systems close all file handles on process exit
  anyway.

Daniel (22 Aug 2002)
- Markus Oberhumer provided some documentation for his previously provided
  CURLOPT_NOSIGNAL fix.

- Patched the lib/Makefile.am to hopefully no longer complain on undefined
  symbols that seemed to occur on builds with shared OpenSSL libraries on
  Solaris lately...

Daniel (20 Aug 2002)
- Fixed compiler warnings on MSCV++ compiles. We're looking for help here:
  remove the pragmas from lib/config-win32.h and adjust the sources where
  the warnings occur. Hiding them with pragmas like this is not the correct
  way of dealing with compiler warnings.

Daniel (13 Aug 2002)
- Ulrich Zadow made the global include files in curl/* include themselves
  using "curl.h" instead of <curl/curl.h> which thus allows people to more
  freely decide how to include curl and how to setup their include paths.

- Sterling Hughes added the curl_share* interface, somewhat as discussed
  previously.

- Jörn Hartroth pointed out that poll() was used in the pre1 source code and
  it isn't very portable, so now I check for it in the configure script and
  work around it.

Version 7.9.9-pre1

Daniel (12 Aug 2002)
- Applied my initial take on making the multi stuff more asynchronous. Connects
  should now return back without "hanging" until it has connected for real.
  This should also be the case for FTP-PASV connects.

Daniel (9 Aug 2002)
- Applied Markus F.X.J. Oberhumer's patch that introduces CURLOPT_NOSIGNAL,
  which effectively prevents libcurl from doing anything that may cause
  signals to get sent. This is basicly for multi-threaded applications that
  now can use timeouts properly, without risking any signals to burst in and
  ruin the party.

Daniel (5 Aug 2002)
- Lukasz Czekierda reported that RFC2732-style literal IPv6 addresses didn't
  work. When did that code vanish? Anyway, it's back again now and seems to
  work!

- Jonatan Lander found out that POSTing an empty string didn't work with the
  command line tool.

Daniel (3 Aug 2002)
- Jörn Hartroth fixed the libcurl.def file to build the windows DLL with
  the multi interface enabled.

Daniel (1 Aug 2002)
- The ftp PORT command now uses a better default IP address, as it will
  extract and use the local IP address used by the control connection.

- Modified the #include lines in curl/multi.h to work better on more
  platforms.

Daniel (31 Jul 2002)
- Attempted a fix for Ray DeGennaro's reported HP-UX host name resolve
  problems.

Daniel (30 Jul 2002)
- Priya Ramakrishnan and Ryan Jones compiles curl/curl.h with a C++ compiler
  and don't get __STDC__ defined, which required us to extend the preprocessor
  check for the ## operator usage.

- Correct the description for CURLOPT_PASSWDFUNCTION, if set to NULL the
  internal default function will be put back.

- danfuzz at milk.com found out that libcurl badly assumed a space after
  'Set-Cookie:' so if it wasn't present, it caused the first letter of the
  cookie name to fall off!

Daniel (29 Jul 2002)
- The password prompt asking for user password used stdout and now uses
  stderr instead to better allow redirecting. It also leaked a fopen() file
  handle that is now fixed.

Daniel (28 Jul 2002)
- HAVE_SETVBUF was left out from src/main.c which made -N not work. Found out
  by M T.

Daniel (26 Jun 2002)
- Glen Nakamura solved a crash in the name resolving function for IP-only
  addresses on Alpha Linux (at least).

- T. Bharath corrected the high resolution timer introduced in 7.9.8.

Daniel (22 Jun 2002)
- Andrés García pointed out man page errors in curl_formadd.3. I fixed.

Daniel (19 Jun 2002)
- Chris Combes pointed out a flaw in curl_escape(). I fixed. We no longer
  tries to generate nor parse '+' in URLs. Spaces become %20, and only %-codes
  are translated by curl_unescape().

Daniel (15 Jun 2002)
- Added --limit-rate to the curl tool. Allows the user to set a maxmimum
  upper limit to how much bandwidth to use for transfers.

- CURLOPT_BUFFERSIZE was added to libcurl. This sets a prefered size for the
  receive buffer in libcurl. The main point of this would be that the write
  callback gets called more often and with smaller chunks.

Daniel (14 Jun 2002)
- Yarram Sunil found out that the SocketIsDead() function performed a lot
  faster on Windows when removing the 1 microsecond timeout.

- Hanno L. Kranzhoff fixed the VC++ project files.

- Tom Mattison found out that ftp transfers closed the connection a little
  too often.

- Miklos Nemeth posted a VC++ makefile fix and some INSTALL comments on how
  to disable specific protocols when building for Windows.

Version 7.9.8

Daniel (13 Jun 2002)
- Time to let this baby go.

Daniel (12 Jun 2002)
- Chris Combes added three new options for curl_formadd(): CURLFORM_BUFFER,
  CURLFORM_BUFFERPTR, CURLFORM_BUFFERLENGTH.  They are used to create a
  multipart that appears as a regular file upload, but the data is provided
  with a pointer and length.

- Nico Baggus made the VMS version use sigsetjmp() too.

- Jörn Hartroth fixed the mingw32 build using the mm lib.

- Applied patches by Kris Kennaway that correct format string problems in
  lib/ftp.c and lib/ldap.c.

Version 7.9.8-pre3

Daniel (11 Jun 2002)
- James Cone brought the idea of using sigsetjmp() in the signal handler to
  make the time-out of name lookups to work, even when the underlying name
  resolver library traps EINTR. The use of sigsetjmp() and siglongjmp() for
  this may be a bit drastic, and also not likely to exist on all platforms.  I
  added careful checking for this in the configure script, even checks for it
  being a macro (which seems to be the case in for example Linux).

  sigsetjmp() seems to be mentioned in the Single Unix specification.

- Miklos Nemeth brought a patch that allows libcurl to get built with specific
  protocols disabled. This is done by running ./configure
  --disable-[protocol].

- FTP range downloads could make CURLE_FTP_WRITE_ERROR get returned. We now
  make precautions to not return this for range downloads.

  Added test case 135 that makes an ftp range download. Had to tweak the
  runtests.pl script a bit too.

- Bug report #566835 identified a strlen() on a NULL pointer. Added additional
  check to prevent this.

Daniel (10 Jun 2002)
- Found and corrected a connect failure problem that didn't create a human
  error text.

- Added code to compile with OpenSSL 0.9.7. Based on patch from Jacob Meuser
  and comments from Götz Babin-Ebell.

- Gautam Mani found a socket descriptor leak that happened when FTP transfers
  failed and you reinvoked curl_easy_perform().

Daniel (5 Jun 2002)
- Gustaf Hui corrected curl_multi_remove_handle() so that it won't crash no
  matter when you decide to remove the CURL handle.

- HAVE_RAND_STATUS was added to lib/config-win32.h by Andreas Olsson, as it
  makes windows builds stop complaining about "weak seeding" when it in fact
  isn't.

- Another 64bit architecture crash that was introduced in 7.9.7 was now
  removed, as bug report #564585 clarified. This happened due to our attempts
  to only allocate only as much memory as is actually needed for name
  resolving (using realloc) which called for a function that could 'move' a
  hostent struct in memory.

Version 7.9.8-pre2

Daniel (3 Jun 2002)
- T. Bharath fixed the CURLINFO_REDIRECT_TIME to return a correct time and
  made the CURLINFO_REQUEST_SIZE return the correct total request size. He
  also made the win32 timers use higher resolution than before.

Daniel (29 May 2002)
- Renaud Chaillat made me aware of the fact that libcurl returned an error if
  you tried to get an empty FTP file. This seemed like a wrong thing to do, so
  now it no longer does that! I just hope that no one built anything fancy
  upon this unexpected behavior...

Daniel (28 May 2002)
- Cris Bailiff brought CURLOPT_CAPATH that works like CURLOPT_CAINFO but
  specifies a path to a directory with certificates rather than a single file
  with them all concatenated. --capath was added to the command line tool
  for the same function.

  Windows users need to pay attention that the directory should be setup with
  the c_rehash tool of the OpenSSL package, and that creates symlinks by
  default that need to be replaced with actual copies to work on Windows.

- Gustaf Hui provided new code that changes how curl_multi_info_read()
  messages are stored, so that they don't have to be kept around for the multi
  handle's entire life time. He also made it return failure codes properly
  which it didn't do before.

Daniel (27 May 2002)
- Gustaf Hui pointed out that running curl_multi_perform() without doing
  curl_multi_fdset() first was not really a working combo. I added an internal
  check for this and have some extra select() code without timeout to make the
  library internals work identically nevertheless. We might need to somehow
  either document that once you've used the *_fdset() you should remain using
  them in select() or you should blank them somehow so that libcurl won't go
  crazy.

Version 7.9.8-pre1

Daniel (22 May 2002)
- James Cone brought an excellent patch, including several tests and docs!
  CURLOPT_NETRC now takes an enum as argument instead of the previous boolean.
  --netrc-optional was introduced as an addition to --netrc to allow the
  command line client to take use of all that new netrc stuff.

- Bug report #558888 showed a case where libcurl re-used the previous host
  name when a connection over a proxy was re-used but to a different target
  host.

Daniel (21 May 2002)
- Edin Kadribasic helped me sort out a problem to made libcurl crash when
  trying to HTTP POST an empty string.

- Clarified that Juergen Wilke donated the original tests/server/sws.c code.

- Jean-Philippe Barrette-LaPierre made curl_formadd() return a typedef named
  CURLFORMcode instead of the previous 'int', and the various return codes are
  now globally exported. It allows applications to better figure out what goes
  wrong when curl_formadd() returns errors.

Daniel (20 May 2002)
- Roland Zimmermann pointed out that SSL_CTX_use_certificate_chain_file()
  is prefered to SSL_CTX_use_certificate_file().

Daniel (17 May 2002)
- Bug report #556869 pointed out that src/writeout.c didn't compile on freebsd
  after my AIX fixes the other week.

- Bug report #556930 pointed out a FreeBSD core dump introduced in 7.9.7 in
  the DNS struct realloc stuff. Actually, this crash could happen on all
  systems that made the pack_hostent() function get invoked.

- I removed several compiler warnings in the test suite's HTTP server.

Version 7.9.7

Daniel (10 May 2002)
- Kevin Roth adjusted the --trace-ascii output slightly.

- Paul Harrington found out that src/writeout.c needed an additional header
  file included for AIX builds

Version 7.9.7-pre2

Daniel (7 May 2002)
- Updated the man page with --trace-ascii and -j/--junk-session-cookies.

- Made --trace-ascii do pretty much the same as --trace but without the hex
  part in the output.

- Added CURLOPT_COOKIESESSION that when enabled makes libcurl ignore session
  cookies read from a file. This option is enforced by the curl command line
  tool using the new -j/--junk-session-cookies option. After discussions with
  Kevin Roth. This makes it easier to use curl to fully emulate a browser's
  behavior, even when it comes to "session cookies". Session cookies are
  cookies that a normal browser discards when the browser is shut
  down. They're identified by not having any expire date/time.

- When CURLOPT_DEBUGDATA was set, it ruined the CURLOPT_STDERR setting and
  this was discovered when --trace was made to crash.

- Using -v and --trace at the same time confused matters. -v is now pretty
  much ignored when --trace or --trace-ascii is used.

- Made --trace (and --trace-ascii) support - as file name to pass output to
  stdout instead. It makes it consistent with how other options work.

Version 7.9.7-pre1

Daniel (6 May 2002)
- Added multi-post.c to the examples directory. I got the basic source for
  this from Gustaf Hui.

Daniel (3 May 2002)
- CURL_MAX_WRITE_SIZE is now an exported #define in the curl/curl.h header and
  can be used to figure out the maximum buffer size your write callback can
  get.

- CURLOPT_READDATA is now an alias for CURLOPT_INFILE and CURLOPT_WRITEDATE is
  an alias for CURLOPT_FILE. These two were added for conformity. Most other
  callback function's userdata are provided with options using a similar name-
  scheme.

- Added "--trace [file]" to the command line tool. It makes a very detailed
  trace dump get stored, with a full protocol dump that includes all received
  and transmitted data. This could be a very effective tool for debugging what
  goes wrong. This dump includes every byte the way it is sent to/received
  from the server. The dump is the plain-text version, so SSL transfers will
  still be readable.

- I found out that the DEBUGFUNCTION was not called properly everywhere as we
  wanted it to. I fixed it.

- -D now stores all headers to the same file if multiple URLs are given on the
  command line! Kevin Roth made me aware of that it didn't already do this!

- Gustaf Hui wrote an excellent formpost example that used the multi
  interface.  Unfortunately, it didn't work due to several bugs in how
  transfers were made when the multi interface was used.

Daniel (2 May 2002)
- Hanno Kranzhoff found out that when doing multiple transfers on the same
  easy handle, the progress meter would show a bad "currently downloaded
  value" when the transfer starts.

Daniel (1 May 2002)
- Applied another patch by Jacky Lam to make the name resolve info realloc()
  stuff work properly.

Daniel (28 April 2002)
- curl_multi_info_read() is now implemented!

Daniel (27 April 2002)
- Updated BUGS, TODO, FAQ, INSTALL and added BINDINGS.

- I think I fixed the DNS cache prune crach Jacky Lam found and reported.

- I cleaned up the name prefix stuff in the hash and llist modules.

- FTP responses should now be better on timing out properly. The timeout value
  is maximum timeout for the entire request operation, but before this, the
  timeout was used as a maximum allowed time between two reads...

Daniel (26 April 2002)
- Fixed the test suite http server to not use snprintf() anymore due to better
  portability.

Daniel (25 April 2002)
- With Sterling Hughes' new DNS pruning, Jacky Lam asked if this wouldn't
  cause problems since the pruning is only checking the entry time, and it
  sure could cause problems. Therefor, I've now added and changed code so that
  this should not be a problem. Nowhere in the code will be store name
  resolved information around so that a sunsequent DNS cache prune should
  cause a problem. This of course called for some mild internal changes.

Daniel (23 April 2002)
- Improved the 'no_proxy' check, as using port numbers in the URL confused it
  previously. Reported by Erwan Legrand in bug report #547484.

- The --interface option now works even on IPv6 enabled builds. Reported by
  'thor'.

Daniel (22 April 2002)
- The #defines names starting with TIMECOND now has CURL_ prefixes. (The old
  names are still #defined too.) Pointed out by Robert Olson.

- Jacky Lam brought code that lets the name resolve function only use as much
  memory as it actually needs. This only works on certain operating systems,
  but is totally transparant to all users.

Daniel (19 April 2002)
- Bjorn Reese fixed pack_hostent to work properly with 64 bit pointers.

Daniel (18 April 2002)
- Sterling Hughes added code to prune old DNS cache entries, since Jacky Lam
  experienced very big caches.

Daniel (17 April 2002)
- Dirk Manske patched the 301 response to work against the RFC but more like
  common browsers do. If a POST get a 301 back, it'll switch to GET in the
  next request (if location-following is enabled).

Daniel (16 April 2002)
- Dirk Manske posted a patch originally written by Ingo Wilken that introduced
  two new CURLINFO_* values: CURLINFO_REDIRECT_TIME and
  CURLINFO_REDIRECT_COUNT.

Daniel (15 April 2002)
- Jonatan Lander patched the verbose text 'Disables POST, goes with GET' to
  reflect reality better, like when the first request isn't POST and when
  the second isn't GET... :-)

- Craig Davison pointed out that when curl_formadd()ing a file that doesn't
  exist, libcurl doesn't return error. Now, curl_easy_perform() will return
  CURLE_READ_ERROR if that is the case. Test 41 was added to verify this.

Version 7.9.6

Daniel (14 April 2002)
- Dirk Manske brought a fix that makes libcurl strip off white spaces from the
  beginning of cookie contents.

- Had to patch include/curl/curl.h since MSVC doesn't set the __STDC__ define.
  Moonesamy pointed out the problem, Bjorn Reese the solution.

Version 7.9.6-pre5

Daniel (12 April 2002)
- Fixed the TIMER_CONNECT to be more accurate for FTP transfers. Previously
  FTP transfers got the "connect done" time set after the initial FTP commands
  and not directly after the TCP/IP connect as it should.

  I also made the time stamp get set even if the connect itself fails, which
  it didn't do previously.

- Jean-Philippe Barrette-LaPierre provided his patch that introduces
  CURLOPT_DEBUGFUNCTION and CURLOPT_DEBUGDATA. They allow a program to a set a
  callback to receive debug/information data. That includes headers and data
  that is received and sent. CURLOPT_VERBOSE still controls it.

  By default, there is an internal debugfunction that will make things look
  and work as before if not changed.

Daniel (10 April 2002)
- Sebastien Willemijns found out that -x didn't use the default port number as
  is documented. It does now.

- libcurl-errors.3 is a new man page attempting to document all libcurl error
  codes

- Added two new error codes and changed the behaviour of two old ones
  slightly:

  CURLE_WRITE_ERROR
   This error was returned *both* for errors that occured when writing
   received data to a local file, as well as when we get problems writing data
   to a remote server. CURLE_SEND_ERROR has now been added for the latter
   error.

  CURLE_READ_ERROR
   This error was similarly returned *both* for errors when reading a local
   file, as well as when getting problems when reading network data.
   CURLE_RECV_ERROR has now been added for the latter error.

 (Two test cases were adjusted accordingly.)

Daniel (9 April 2002)
- runtests.pl now sets the HOME variable before running curl, to prevent any
  actual ~/.curlrc file to fool the tests!

Version 7.9.6-pre4

Daniel (8 April 2002)
- Michael Curtis provided new functionality for curl on some platforms. Using
  the --environment option, curl will *set* a bunch of environment variables
  to values. The names are the same ones as for the -w/--writeout option.

  For now, this only works on the RISC OS version, as this feature relies on
  both OS support and that it matches OS paradigms.

- Jacky Lam provided a fix for getting headers-only when the reply is HTTP/1.0
  and 304, I edited it slightly.

Daniel (5 April 2002)
- As requested by Jay Graves, the '.curlrc' file (or _curlrc as it is called
  when used in windows), is now loaded from the current directory if the HOME
  environment variable isn't set (or if it is too long). I also enlarged the
  array used to store the full file path in, to 512 bytes.

- Kevin Roth pointed out to me why the "19 March" change regarding -G and -I
  was stupid and the change was reverted. Added test case 48 to verify the
  functionality.

Version 7.9.6-pre3

Daniel (4 April 2002)
- Jonatan Lander brought a patch that makes curl/curl.h compile nicely on
  pre-ISO compilers, like when using gcc -traditional.

Daniel (3 April 2002)
- Jacky Lam identified a glitch when getting headers-only, where libcurl would
  "hang" 1 second in vain in the select() loop before returning back.

- Tor Arntsen brought a patch for multipart formposts. It turned out that the
  "CGI_Lite Perl package" makes some bad assumptions on what letters that may
  be used in boundary strings and thus curl could confuse it by including '+'
  and '/'. While this is standards-compliant, we change the behavior to work
  smoothly with existing software based on that package.

Daniel (2 April 2002)
- Gerhard Herre filed bug report #536238 where he pointed out a crash in
  verbose FTP passive transfers for AIX.

- Clarence Gardner pointed out a minor flaw in how libcurl didn't properly
  take care of all errors that SSL_read() could return.

- Jacky Lam fixed a MALLOCDEBUG problem in lib/getinfo.c

Daniel (27 March 2002)
- T. Bharath pointed out a flaw in the connection re-use function that didn't
  check proxy connections properly for "deadness" before they were re-used.

- Pedro Neves found out that HTTP POSTing with --data-binary did not properly
  work under Windows as the file specified wasn't read fully binary!

Daniel (25 March 2002)
- Jacky Lam brought a fix that improves treatment of cookies using identical
  domains but with leading dots properly.

Daniel (22 March 2002)
- Miklos Nemeth updated the windows section of the docs/INSTALL file and the
  windows makefiles.

- Jon Dillon provided us with several good-looking curl images for
  promotion. View them here https://curl.haxx.se/icons.html

Daniel (20 March 2002)
- Peter Verhas found out that CRLF replacement in uploads was not working. I
  fixed it, and added test case 128 that verifies the functionality.

- The list formerly known as curl-main is now named curl-users and is hosted
  by sourceforge. Susbcribe to the new list, get off the old one.

Version 7.9.6-pre2

Daniel (19 March 2002)
- Made -G and -I on the same command line cause an error.

- Moved the multi.h file to the "public" include directory and made it get
  included by curl.h so that no extra include files will be necessary to use
  it.

  Added docs and man pages for the multi interface to the release archive.
  Added the three example source codes too.

  Necessary steps in my campaign to sneak in the multi interface... ;-)

- Updated the year in all copyright notices in all C and H files.

Daniel (18 March 2002)
- Tomas Szepe found out that -d and -G didn't mix as they should. I broke this
  in 7.9.5... Added test case 32 for this.

Version 7.9.6-pre1

Daniel (16 March 2002)
- Peter Verhas pointed out that the curl_escape and curl_unscape man pages
  contained factual errors.

- Albert Choy found and corrected a problem with the verbose output when doing
  PASV ftp transfers. It could make libcurl crash.

  Details in bug report #530562:
  https://sourceforge.net/p/curl/bugs/178/

Daniel (15 March 2002)
- Jun-ichiro itojun Hagino filed bug report #530204 that clearly pointed out
  the PF_INET fix from February 19 as a not-very-good fix as it broke IPv6
  capability! That patch is now reverted.

  The problem with slow name lookups with getaddrinfo() on non-IPv6 enabled
  hosts are instead made by first checking if the stack is IPv6-enabled and if
  not, the PF_INET is used and otherwise we go with the full PF_UNSPEC.

- T. Bharath pointed out that when we return an "error" from a WRITEFUNCTION
  as described in the man page, libcurl did not return the documented error
  code (CURLE_WRITE_ERROR) but would instead return CURLE_READ_ERROR. This is
  now corrected.

Daniel (14 March 2002)
- Setting CURLOPT_POST without setting CURLOPT_POSTFIELDS now read the POST-
  data from the callback.

- The GOPHER support seems to be broken. I don't think I'll even start fixing
  it until someone else finds out... :-)

Daniel (13 March 2002)
- Trying 'curl -I ftp.sunet.se' or similar did a SIZE on a silly "(nil)"
  string. If such a file would be present, curl returned the size of it! Now
  we prevent this.

- Curl_sendf() was fixed to deal with situation where Curl_write() would've
  blocked and thus return -1.

- Setting CURLOPT_PROGRESSFUNCTION to NULL now restores the internal function.

- All CURLFORM_* options can now be used in a CURLFORM_ARRAY except the
  CURLFORM_ARRAY itself. This was necessary since we couldn't expand the
  CURLFORM_* list proprely and unrestricted until this was the case. It was
  also a bit peculiar to users why some options could be used in an array
  while others couldn't.

- Removed some silly CRLF lines that had accidentally slipped into src/main.c
  Nico Baggus pointed them out to me.

Daniel (11 March 2002)
- CURLFORM_FILENAME was added. This can be set when creating a file upload
  part, to set the 'filename' field to a custom value. If this isn't used,
  the actually used filename will be included instead (as libcurl always has
  done). curl was adjusted accordingly, and now -F accepts a 'filename=' field
  too, and allows constructs such as:

    -F 'name=@filename;filename=/dev/null'

  and this can be combined with type= too, in a manner similar to:

   -F "file=@log/test39.txt;filename=fakerfile;type=moo/foobar"

  Test case 39 was added to verify this functionality.

- The struct formerly known as HttpPost is now named curl_httppost to properly
  use the curl name space. I added a #define for the old name to make existing
  programs compile even when this new include file is used.

Daniel (8 March 2002)
- Clifford also discovered that if the client code failed early, as when doing
  "curl -O" only, it would do fclose(NULL) which caused a segmentation fault
  on some systems.

- Clifford Wolf provided a patch that made --progress-bar work again.

- I closed bug report #527032 by making sure that we add a newline after a
  transfer when --progress-bar has been used. Before, without the newline, it
  made the subsequent text come out wrong.

Version 7.9.5

Daniel (7 March 2002)
- Added docs/KNOWN_BUGS to the release archive.

Daniel (6 March 2002)
- Kevin Roth corrected a flaw in the curl client globbing code that made it
  mess up backslashes. This was most notable on windows (cygwin) machines when
  using file://.

- Brad provided another fix for building outside the source-tree.

- Ralph Mitchell patched away a few compiler warnings in tests/server/sws.c

Daniel (5 March 2002)
- I noticed that the typedef in curl.h for the progress callback prototype was
  wrong and thus applications that used it would not get the proper input
  data. It used size_t where the implementation actually uses doubles!

  I wish I could blame someone else, but this was my fault. Again.

Version 7.9.5-pre6

Daniel (4 March 2002)
- Cut off the changes done during 2001 from this changelog file and put them
  in a separate file (CHANGES.2001), available from CVS of course.

- I removed the multi directory. The example sources were moved to the
  docs/examples directory where they belong.

- Wrote 7 new man pages for the current functions in the new multi interface.
  They're all still pretty basic, but we can use them as a start and add more
  contents to them when we figure out what to write. The large amount of man
  pages for libcurl now present made me decide to put them in a new separate
  subdirectory in the docs directory. Named libcurl.

- Giuseppe Corbelli provided a template file for the EPM package manager, it
  gets generated nicely by the configure script now.

Version 7.9.5-pre5

Daniel (1 March 2002)
- Moved the memanalyze.pl script into the tests/ dir and added it to the
  release archives. It was previously only present in the CVS tree.

- Modified the February 17th Host: fix, as bug report #523718 pointed out that
  it caused crashes!

- Nico Baggus added more error codes to the VMS stuff.

- Wesley Laxton brought the code that introduced the new CURLOPT_PREQUOTE
  option. It is just another FTP quote option that allows the user to specify
  a list of FTP commands to issue *just before* the transfer command (RETR or
  STOR etc). It has turned up a few systems that really need this.

  The curl command line tool can also take advantage of this by prefixing the
  quote commands with a plus (+) in similar style that post transfer quote
  commands are specified.

  This is not yet documented. There is no test case for this yet.

Daniel (28 February 2002)
- Ralph Mitchell made some serious efforts and put a lot of sweat in setting
  up scripts and things for me to be able to repeat his problems, and I
  finally could.  I found a problem with the header byte counter that wasn't
  increased properly and thus we could return CURLE_GOT_NOTHING when we in
  fact had received data.

Daniel (27 February 2002)
- I had to revert the non-space parsing cookie fix I posted to the mailing
  list. Expire dates do have spaces and still need to get parsed properly!
  Instead we just ignore trailing white space and it seems to work...

Daniel (26 February 2002)
- Made the cookie property 'Max-Age' work, just since we already tried to
  support it, it is better to do it right. No one uses this anyway.

- The cookie parser could crash if a really weird (illegal) cookie line was
  received. I also made it better discard really oddly formatted lines better.

  Made the cookie jar store the second field from the left using the syntax
  that Netscape and Mozilla probably like. Curl itself ignores it.

  Added test case 31 for these cases.

  Clay Loveless' email regarding some cookie issues started my cleanup.

- Kevin Roth pointed out that my automake fiddles broke the ability to build
  outside the source-tree and I posted a patch to the mailing list that brings
  this ability back.

Version 7.9.5-pre4

Daniel (25 February 2002)
- Fiddled with the automake files to make all source files in the lib
  directory not have ../src in the include path, and the src sources shouldn't
  have ../lib!

- All 79 test cases ran OK under Linux and Solaris using the new HTTP server
  in the test suite. The new HTTP server was first donated by Georg Horn and
  subsequently modified to work with the test suite. It is currently still not
  portable enough to run on "all over" but this is a start and I can run all
  curl tests on my machines. This is an important requirement for the upcoming
  public release.

- Using -d and -I on the same command line now reports an error, as it implies
  two different HTTP requests that can't be mixed.

- Jeffrey Pohlmeyer provided a patch that made the -w/--write-out option
  support %{content_type} to get the content type of the recent download.

- Kevin Roth reported that pre2 and pre3 didn't compile properly on cygwin,
  and this was because I used #ifdef HAVE_WINSOCK_H in lib/multi.h to figure
  out if we could include winsock.h which turns out not to be a wise choice to
  do on cygwin since it has the file but can't include it!

Daniel (22 February 2002)
- Added src/config-vms.h to the release archive.

- Fixed the connection timeout value again, the change from February 18 wasn't
  complete.

Version 7.9.5-pre3

Daniel (21 February 2002)
- Kevin Roth and Andrés García both found out that lib/config.h.in was missing
  in the pre-release archive and thus the configure script failed.

Version 7.9.5-pre2

Daniel (20 February 2002)
- Andrés García provided a solution to bug report #515228. the total time
  counter was not set correctly when -I was used during some conditions (all
  headers were read in one single read).

- Nico Baggus provided a huge patch with minor tweaks all over to make curl
  compile nicely on VMS.

Daniel (19 February 2002)
- Rick Richardson found out that by replacing PF_UNSPEC with PF_INET in the
  getaddrinfo() calls, he could speed up some name resolving calls with an
  order of magnitudes on his Redhat Linux 7.2.

- Philip Gladstone found a second INADDR_NONE problem where we used long
  intead of in_addr_t which caused 64bit problemos. We really shouldn't define
  that on two different places.

Daniel (18 February 2002)
- Philip Gladstone found a problem in how HTTP requests were sent if the
  request couldn't be sent all at once.

- Emil found and corrected a bad connection timeout comparison that made curl
  use the longest of connect-timeout and timout as a timeout value, instead of
  the shortest as it was supposed to!

- Aron Roberts provided updated information about LDAP URL syntax to go into
  the manual as a replacement for the old references.

Daniel (17 February 2002)
- Philip Gladstone pointed out two missing include files that made curl core
  dump on 64bit architectures. We need to pay more attention on these details.
  It is *lethal* to for example forget the malloc() prototype, as 'int' is
  32bit and malloc() must return a 64bit pointer on these platforms.

- Giaslas Georgios fixed a problem with Host: headers on repeated requests on
  the same handle using a proxy.

Daniel (8 February 2002)
- Hanno L. Kranzhoff accurately found out that disabling the Expect: header
  when doing multipart formposts didn't work very well. It disabled other
  parts of the request header too, resulting in a broken header. When I fixed
  this, I also noticed that the Content-Type wasn't possible to disable. It is
  now, even though it probably is really stupid to try to do this (because of
  the boundary string that is included in the internally generated header,
  used as form part separator.)

Daniel (7 February 2002)
- I moved the config*.h files from the root directory to the lib/ directory.

- I've added the new test suite HTTP server to the CVS repository, It seems to
  work pretty good now, but we must make it get used by the test scripts
  properly and then we need to make sure that it compiles, builds and runs on
  most operating systems.

Version 7.9.5-pre1

Daniel (6 February 2002)
- Miklos Nemeth provided updated windows makefiles and INSTALL docs.

- Mr Larry Fahnoe found a problem with formposts and I managed to track down
  and patch this bug. This was actually two bugs, as the posted size was also
  said to be two bytes too large.

- Brent Beardsley found out and brought a correction for the
  CURLINFO_CONTENT_TYPE parser that was off one byte. This was my fault, I
  accidentaly broke Giaslas Georgios' patch.

Daniel (5 February 2002)
- Kevin Roth found yet another SSL download problem.

Version 7.9.4

- no changes since pre-release

Version 7.9.4-pre2

Daniel (3 February 2002)
- Eric Melville provided a few spelling corrections in the curl man page.

Daniel (1 February 2002)
- Andreas Damm corrected the unconditional use of gmtime() in getdate, it now
  uses gmtime_r() on all hosts that have it.

Daniel (31 January 2002)
- An anonymous bug report identified a problem in the DNS caching which made it
  sometimes allocate one byte too little to store the cache entry in. This
  happened when the port number started with 1!

- Albert Chin provided a patch that improves the gethostbyname_r() configure
  check on HP-UX 11.00.

Version 7.9.4-pre1

Daniel (30 January 2002)
- Georg Horn found another way the SSL reading failed due to the non-blocking
  state of the sockets! I fixed.

Daniel (29 January 2002)
- Multipart formposts now send the full request properly, including the CRLF.
  They were previously treated as part of the post data.

- The upload byte counter bugged.

- T. Bharath pointed out that we seed SSL on every connect, which is a time-
  consuming operation that should only be needed to do once. We patched
  libcurl to now only seed on the first connect when unseeded. The seeded
  status is global so it'll now only happen once during a program's life time.

  If the random_file or egdsocket is set, the seed will be re-made though.

- Giaslas Georgios introduced CURLINFO_CONTENT_TYPE that lets
  curl_easy_getinfo() read the content-type from the previous request.

Daniel (28 January 2002)
- Kjetil Jacobsen found a way to crash curl and after much debugging, it
  turned out it was a IPv4-linux only problem introduced in 7.9.3 related to
  name resolving.

- Andreas Damm posted a huge patch that made the curl_getdate() function fully
  reentrant!

- Steve Marx pointed out that you couldn't mix CURLOPT_CUSTOMREQUEST with
  CURLOPT_POSTFIELDS. You can now!

Daniel (25 January 2002)
- Krishnendu Majumdar pointed out that the header length counter was not reset
  between multiple requests on the same handle.

- Pedro Neves rightfully questioned why curl always append \r\n to the data
  that is sent in HTTP POST requests. Unfortunately, this broke the test suite
  as the test HTTP server is lame enough not to deal with this... :-O

- Following Location: headers when the connection didn't close didn't work as
  libcurl didn't properly stop reading. This problem was added in 7.9.3 due to
  the restructured internals. 'Frank' posted a bug report about this.

Daniel (24 January 2002)
- Kevin Roth very quickly spotted that we wrongly installed the example
  programs that were built in the multi directory, when 'make install' was
  used. :-/

Version 7.9.3

Daniel (23 January 2002)
- Andrés García found a persistancy problem when doing HTTP HEAD, that made
  curl "hang" until the connection was closed by the server. This problem has
  been introduced in 7.9.3 due to internal rewrites, this was not present in
  7.9.2.

Version 7.9.3-pre4

Daniel (19 January 2002)
- Antonio filed bug report #505514 and provided a fix! When doing multipart
  formposts, libcurl would include an error text in the actual post if a
  specified file wasn't found. This is not libcurl's job. Instead we add an
  empty part.

Daniel (18 January 2002)
- Played around with stricter compiler warnings for gcc (when ./configure
  --enable-debug is used) and changed some minor things to stop the warnings.

- Commented out the 'long long' and 'long double' checks in configure.in, as
  we don't currently use them anyway and the code in lib/mprintf.c that use
  them causes warnings.

- Saul Good and jonatan pointed out Mac OS X build problems with pre3 and how
  to correct them. Two compiler warnings were removed as well.

- Andrés García fixed two minor mingw32 building problems.

Version 7.9.3-pre3

Daniel (17 January 2002)
- docs/libcurl-the-guide is a new tutorial for our libcurl programming
  friends.

- Richard Archer brought back the ability to compile and build with OpenSSL
  versions before 0.9.5.
  [https://sourceforge.net/p/curl/bugs/149/]

- The DNS cache code didn't take the port number into account, which made it
  work rather bad on IPv6-enabled hosts (especially when doing passive
  FTP). Sterling fixed it.

Daniel (16 January 2002)
- Georg Horn could make a transfer time-out without error text. I found it and
  corrected it.

- SSL writes didn't work, they return an uninitialized value that caused
  havoc all over. Georg Horn experienced this.

- Kevin Roth patched the curl_version() function to use the proper OpenSSL
  function for version information. This way, curl will report the version of
  the SSL library actually running right now, not the one that had its headers
  installed when libcurl was built. Mainly intersting when running with shared
  OpenSSL libraries.

Version 7.9.3-pre2

Daniel (16 January 2002)
- Mofied the main transfer loop and related stuff to deal with non-blocking
  sockets in the upload section. While doing this, I've now separated the
  connection oriented buffers to have one for downloads and one for uploads
  (as two can happen simultaneously). I also shrunk the buffers to 20K
  each. As we have a scratch buffer twice the size of the upload buffer, we
  arrived at 80K for buffers compared with the previous 150K.

- Added the --cc option to curl-config command as it enables so very cool
  one-liners. Have a go a this one, building the simple.c example:

        $ `curl-config --cc --cflags --libs` -o example simple.c

Daniel (14 January 2002)
- I made all socket reads (recv) handle EWOULDBLOCK. I hope nicely. Now we
  only need to address all writes (send) too and then I'm ready for another
  pre-release...

- Stoned Elipot patched the in_addr_t configure test to make it work better on
  more platforms.

Daniel (9 January 2002)
- Cris Bailiff found out that filling up curl's SSL session cache caused a
  crash!

- Posted the curl questionnaire on the web site. If you haven't posted your
  opinions there yet, go there and do it now while it is still there:

        https://curl.haxx.se/q/

- Georg Horn quickly found out that the SSL reading no longer worked as
  supposed since the switch to non-blocking sockets. I've made a quick patch
  (for reading only) but we should improve it even further.

Version 7.9.3-pre1

Daniel (7 January 2002)
- I made the 'bool' typedef use an "unsigned char". It makes it the same on
  all platforms, no matter what the platform thinks the default format for
  char is. This was noticed since we made a silly comparison involving such a
  bool variable, and only one compiler/platform combination (on Debian Linux)
  complained about it (that happened to have its char unsigned by default).

- Bug report #495290 identified a cookie parsing problem that was corrected.
  When a Set-Cookie: line is received without a trailing semicolon, libcurl
  didn't read the last "name=value" pair of the line, leading to confusions...

- Sterling committed his updated DNS cache code.

- I worked with Georg Horn and comments from Götz Babin-Ebell and switched
  curl's socket operations completely over to non-blocking for the entire
  operation (previously we used non-blocking only for the connection phase).
  We had to do this to make the SSL connection phase timeout properly without
  the use of signals. A little extra code to deal with this was added.

- T. Bharath pointed out a slightly obscure cookie engine flaw.

- Pete Su pointed out that libcurl didn't treat HTTP code 204 as it should.
  204-replies never provides a response-body. This resulted in bad persistant
  behavior when 204 was received.

Daniel (5 January 2002)
- SM updated the VC++ library Makefiles for the new source files.

Daniel (4 January 2002)
- I discovered that we wrongly used inet_ntoa() (instead of inet_ntoa_r() in
  two places in the source code). One happened with VERBOSE set on connects,
  and the other when VERBOSE was on and krb4 over nat was used... I honestly
  don't think anyone has suffered from these mistakes.

- I replaced a lot of silly occurances of printf() to instead use the more
  appropriate Curl_infof() or Curl_failf(). The krb4 and telnet code were
  affected.

- Philip Gladstone found a few more problems with 64-bit archs (the 64-bit
  sparc on solaris 8).

- After discussions on the libcurl list with Raoul Cridlig, I just made FTP
  response lines get passed to the header callback if such a one is
  registered. It'll make it possible for any application to get all the
  responses an FTP server sends to libcurl.

Daniel (3 January 2002)
- Sterling Hughes brought a few buckets of code. Now, libcurl will
  automatically cache DNS lookups and re-use the previous results first if any
  such is available. It greatly improves speed when doing many repeated
  operations to the same host.

- As the test case uses --include and then --head, I had to modify src/main.c
  to deal with this situation slightly better than previously. When done, we
  have 100% good tests again in the main branch.

Daniel (2 January 2002)
- Made test case 25 run again in the multi-dev branch. But it seems that the
  changes done on dec-20 made test case 104 cease to work (in both branches).

- Philip Gladstone pointed out a few portability problems in the source code
  that didn't compile on 64-bit sparcs using Sun's native compiler.
Daniel (20 December 2001)
- Björn Stenberg caught an unpleasent (but hard-to-find) bug that could cause
  libcurl to hang on transfers over proxy, when the proxy was specified with
  an environment variable!

- Added code to make ftp operations treat the NO_BODY and HEADERS options
  better:

   NO_BODY set TRUE and HEADERS set TRUE:
    Return a set of headers with file info

   NO_BODY set FALSE
    Transfer data as usual, HEADERS is ignored

   NO_BODY set TRUE and HEADERS set FALSE
    Don't transfer any data, don't return any headers. Just perform the set
    of FTP commands.

Daniel (17 December 2001)
- Götz Babin-Ebell dove into the dark dungeons of the OpenSSL ENGINE stuff and
  made libcurl support it! This allows libcurl to do SSL connections with the
  private key stored in external hardware.

  To make this good, he had to add a bunch of new library options that'll be
  useful to others as well:

   CURLOPT_SSLCERTTYPE  set SSL cert type (PEM/DER)
   CURLOPT_SSLKEY       set SSL private key (file)
   CURLOPT_SSLKEYTYPE:  set SSL key type (PEM/DER/ENG)
   CURLOPT_SSLKEYPASSWD: set the passphrase for your private key
                          (CURLOPT_SSLCERTPASSWD is an alias)
   CURLOPT_SSLENGINE:   set the name of the crypto engine
                        (returns CURLE_SSL_ENGINE_NOTFOUND on error)
   CURLOPT_SSLENGINE_DEFAULT: set the default engine

  There are two new failure codes:

   CURLE_SSL_ENGINE_NOTFOUND
   CURLE_SSL_ENGINE_SETFAILED

Daniel (14 December 2001)
- We have "branched" the source-tree at a few places. Checkout the CVS sources
  with the 'multi-dev' label to get the latest multi interface development
  tree. The idea is to only branch affected files and to restrict the branch
  to the v8 multi interface development only.

  *NOTE* that if we get bug reports and patches etc, we might need to apply
  them in both branches!

  The multi-dev branch is what we are gonna use as main branch in the future
  if it turns out successful. Thus, we must maintain both now in case we need
  them. The current main branch will be used if we want to release a 7.9.3 or
  perhaps a 7.10 release before version 8. Which is very likely.

- Marcus Webster provided code for the new CURLFORM_CONTENTHEADER option for
  curl_formadd(), that lets an application add a set of headers for that
  particular part in a multipart/form-post. He also provided a section to the
  man page that describes the new option.

Daniel (11 December 2001)
- Ben Greear made me aware of the fact that the Curl_failf() usage internally
  was a bit sloppy with adding newlines or not to the error messages. Let's
  once and for all say that they do not belong there!

- When uploading files with -T to give a local file name, and you end the URL
  with a slash to have the local file name used remote too, we now no longer
  use the local directory as well. Only the file part of the -T file name
  will be appended to the right of the slash in the URL.

Daniel (7 December 2001)
- Michal Bonino pointed out that Digital Unix doesn't have gmtime_r so the
  link failed. Added a configure check and corrected source code.

Version 7.9.2

Daniel (5 December 2001)
- Jon Travis found out that if you used libcurl and CURLOPT_UPLOAD and then
  on the same handle used CURLOPT_HTTPGET it would still attempt to upload.
  His suggested fix was perfect.

Daniel (4 December 2001)
- Incorporated more macos fixes and added four specific files in a new
  subdirectory below src.

Daniel (3 December 2001)
- Eric Lavigne reported two problems:

  First one in the curl_strnequal() function. I think this problem is rather
  macos 9 specific, as most platform provides a function to use instead of the
  one provided by libcurl.

  A second, more important, was in the way we take care of FTP responses. The
  code would read a large chunk of data and search for the end-of-response
  line within that chunk. When found, it would just skip the rest of the
  data. However, when the network connections are special, or perhaps the
  server is, we could actually get more than one response in that chunk of
  data so that when the next invoke to this function was done, the response
  had already been read and thrown away. Now, we cache the data not used in
  one call, as it could be useful in the subsequent call. Test case 126 was
  added and the test ftp server modified, to exercise this particular case.

Version 7.9.2-pre8

Daniel (2 December 2001)
- Bug report #487825 correctly identified a problem when using a proxy and
  following a redirection from HTTP to HTTPS. libcurl then re-used the same
  proxy connection but without doing a proper HTTPS request.

- Fixed win32 compiling quirks.

Version 7.9.2-pre7

Daniel (30 November 2001)
- Documented --disable-epsv and CURLOPT_FTP_USE_EPSV.

Daniel (29 November 2001)
- Added --disable-epsv as an option. When used, curl won't attempt to use the
  EPSV command when doing passive FTP downloads. Wrote a test case for it.

- Eric provided a few more fixes for building on Macs. He also pointed out
  a flaw in the signal handler restoration code.

Daniel (28 November 2001)
- Fiddled with some Tru64 problems reported by Dimitris Sarris. They appeared
  only when using VERBOSE ftp transfers. Do we use a too small buffer for
  gethostbyaddr_r(), was the lack of using in_addr_t wrong or is it that the
  hostent struct must be blanked before use? With Dimitris help and these
  patches, the problems seem to be history.

- CURLOPT_FTP_USE_EPSV was added and can be set to FALSE to prevent libcurl
  from using the EPSV command before trying the normal PASV. Heikki Korpela
  pointed out that some firewalls and similar don't like the EPSV so we must
  be able to shut if off to work everywhere.

- I added a configure check for 'in_addr_t' and made the ftp code use that to
  receive the inet_addr() return code in. Works on Solaris and Linux at
  least. The Linux man page for inet_addr() doesn't even mention in_addr_t...

- Adjusted (almost) all FTP tests to the new command sequence.

- FTP command sequence changes:

  EPSV is now always attempted before PASV. It is the final touch to make IPv6
  passive FTP downloads to work, but EPSV is not restricted to IPv6 but works
  fine with IPv4 too on the servers that support it.

  SIZE is now always issued before RETR. It makes curl know the actual
  download size before the download takes place, as it makes it less important
  to find the size sent in RETR responses. Many sites don't include the size
  in there.

  Both these changes made it necessary to change the test suite's ftp server
  code, and all FTP test cases need to be checked and adjusted!

Daniel (27 November 2001)
- Hans Steegers pointed out that the telnet code read from stdout, not stdin
  as it is supposed to do!

Version 7.9.2-pre6

Daniel (27 November 2001)
- Eric Lavigne's minor changes to build on MacOS before OS X were applied.

- greep at mindspring.com provided a main index.html page for our release
  archive docs directory. It just links to all the existing HTML files, but
  I think it may come useful to people.

- There's now some initial code to support the EPSV FTP command. That should
  be used to do passive transfers IPv6-style. The code is still #if 0'ed in
  lib/ftp.c as I have no IPv6 ftp server to test this with.

Daniel (26 November 2001)
- Robert Schlabbach had problems to understand how to do resumed transfers,
  and I clarified the man page -C section somewhat.

Version 7.9.2-pre5

Daniel (22 November 2001)
- Andrés García helped me out to track down the roots of bug report #479537,
  which was concerning curl returning the wrong error code when failing to
  connect. This didn't happen on all systems, and more specificly I've so far
  only seen this happen on IPv4-only Linux hosts.

- I applied the fixes for the two bugs Eric Lavigne found when doing his MacOS
  port. A missing comma in arpa_telnet.h and a pretty wild write in the FTP
  response reader function. The latter write is however likely to occur in our
  own buffer unless very big FTP server replies (>25K) are read. I've never
  seen such a reply ever, so I think this is a relatively minor risk.

Daniel (21 November 2001)
- Moonesamy provided code to prevent junk from being output when libcurl
  returns an error code but no error description and that corrects how make is
  run in the Makefile.dist file (that appears as root Makefile in release
  archives).

- Eric Lavigne mailed me bugfixes and patches for building libcurl on MacOS
  (non-X).

- Kevin Roth modified the cygwin files once again, now to build against the
  shared OpenSSL DLLs.

Version 7.9.2-pre4

Daniel (20 November 2001)
- Georg Horn brought a patch that introduced CURLINFO_STARTTRANSFER_TIME,
  complete with man page updates!

Daniel (19 November 2001)
- Miklos Nemeth provided details enough to update the Borland makefile
  properly.

- Lars M Gustafsson found a case with a bad free(). In fact, it was so bad I'm
  amazed we never saw this before!

- Kevin Roth patched the cygwin Makfile.

Daniel (16 November 2001)
- Klevtsov Vadim fixed a bug in how time-conditionals were sent when doing
  HTTP.

Version 7.9.2-pre3

Daniel (14 November 2001)
- Samuel Listopad patched away the problem with SSL we got when someone call
  curl_global_init() => curl_global_cleanup() => curl_global_init(). The
  second init would not "take" and SSL would be unusable with curl from that
  point. This doesn't change the fact that calling the functions that way is
  wrong. curl_global_init() should be called exactly once and not more.

Daniel (13 November 2001)
- Fixed some minor variable type mixups in ftp.c that caused compiler warnings
  on HP-UX 11.00.

- The FTP fix I did yesterday used an uninitialized variable that caused
  spurious errors when doing FTP.

Version 7.9.2-pre2

Daniel (12 November 2001)
- Ricardo Cadime fell over a multiple-requests problem when first a FTP
  directory fetch failed and then a second request is made after that. The
  second request happened to get the FTP server response back from the
  previous request, when it did its initial CWD command.

- Bjorn Reese pointed out that we could improve the time diff function to
  prevent truncation a bit.

- Kai-Uwe Rommel made me aware that -p (http proxy tunnel) silly enough didn't
  work for plain HTTP requests! So I made that work.

Version 7.9.2-pre1

Daniel (12 November 2001)
- Rewrote the Curl_ConnectHTTPProxyTunnel(). It should now not only work a lot
  faster, it should also support such ("broken") proxies that John Lask
  previously have reported problems with. His proxy sends a trailing zero byte
  after the end of the (proxy-) headers. I've tested this myself and it seems
  to work on a proxy the previous version also worked with...! This rewrite is
  due to the problems John Lask previously experienced.

- Andrés García found out why the "current speed" meter sometimes showed 2048K
  for very quick transfers. It turned out the "time diff"-function returned a
  zero millisecond diff. We now always say it is at least one millisecond! In
  reality, these timers very rarely have that good resolution so even though
  the time diff was longer than 1 millisecond, it was reported as no diff.

- I also modified the getinfo() again when returning times, as Paul Harrington
  reports that 7.9.1 only returns times with 1 second accuracy, which indeed
  is wrong.

Daniel (8 November 2001)
- Marcus Webster found out that curl_formadd() could read one byte outside a
  buffer boundary, which then of course could lead to a crash. Marcus also
  gracefully provided a patch for this this.

- Glen Scott ran configure on his Cobalt Qube and it didn't figure out the
  correct way of calling gethostbyname_r() and thus failed to resolve hosts.
  This is two errors: it shouldn't continue the configure script if it finds
  gethostbyname_r() but can't figure out how to use it, and it should really
  figure out how to use it as it was running Linux and we know how that
  works...

Daniel (7 November 2001)
- docs/VERSIONS is a new file in the archive that explains the version number
  system we use in the curl project.

- Did some more fixes that now makes libcurl only ignore signals as long as
  it needs to, and then restore (if any) previous signal handler again.

Daniel (6 November 2001)
- Enrik Berkhan posted bug report #478780, in which he very correctly pointed
  out two bad timeout matters in libcurl: we didn't restore the sigaction
  struct (the alarm handler for SIGALRM) nor did we restore the previous
  alarm() timeout that could've been set by a "parent" process or similar.

- Kevin Roth made the cygwin binary get stripped before install.

Daniel (5 November 2001)
- Detlef Schmier reported that curl didn't compile using Solaris 8 with the
  native cc compiler. It was due to a bad function prototype. Fixed now.
  Unfortunately, I can't enable the -Wstrict-prototypes in my debug builds
  though, as gcc then complains like crazy on OpenSSL include files... :-(

- John Lask provided SSL over HTTP proxy fixes. They'll need some tweaking
  to work on all platforms.

- John Lask added the -1/--TLSv1 options that forces SSL into using TLS
  version 1 when speaking HTTPS.

- John Lask brought a brand new VC++ makefile for the lib directory, that
  works a lot better than the previous!

- Ramana Mokkapati brought some clever insights on the LDAP failures (bug
  report #475407), and his suggested changes are now applied.

Version 7.9.1

Daniel (4 November 2001)
- I've added a number of new test cases the last few days. A few of them since
  I got reports that hinted on problems on timeouts, so I added four tests
  with timeouts for all sorts of protocols and stuff. I also came to think of
  a few other error scenarios that we currently didn't test properly, so I
  wrote up tests for a few of those too.

Daniel (2 November 2001)
- Replaced read() and write() with recv() and send() for socket operations
  even under normal unixes.

Daniel (1 November 2001)
- When an FTP transfer was aborted due to a timeout, it wasn't really aware of
  how many bytes that had been transferred and the error text always said 0
  bytes. I modified this to output the actually transferred amount! :-)

- The FTP fixes in pre7 didn't compile on IPv6 enabled hosts. Does now. I also
  added more comments in the lib/ftp.c source file.

- Minor updates to the FAQ, added a brand new section to the web site about
  the name issue (who owns "curl"? will someone sue us? etc etc):
  https://curl.haxx.se/legal/thename.html

Version 7.9.1-pre7

Daniel (31 October 2001)
- The curl_easy_getinfo() timers accidentally lost their subsecond accuracy as
  the calculations used longs instead of doubles! Paul Harrington reported.

- The SSL SocketIsDead() checks weren't good enough (as expected really), so I
  had to add a generic internal try-it-out system. If the request on a re-used
  connection seems to fail, then we go back and get a new (fresh) connection
  and re-tries the request on that instead. It kind of makes the
  SocketIsDead() check obsolete, but I think it is a quicker way for those
  cases where it actually discovers that the connection is dead.

- When fixing the above, I noticed that we did quite a few writes to sockets
  in libcurl where we didn't check the return code (that it actually worked to
  send the data). With the new "attempted request" system we must detect those
  situations so I went over a bunch of functions, changed return types and
  added checks for what they actually return.

Version 7.9.1-pre6

Daniel (31 October 2001)
- Paul Harrington detected a problem with persistant SSL connections. Or to be
  more exact, we didn't properly detect that the connection was dead and then
  a second connection would try to re-use it wrongly. The solution to this
  problem is still not very clear and I'm working on it. One OpenSSL insider
  said there is no way to know if the SSL connection is alive or not without
  actually trying an operation.

Daniel (30 October 2001)
- If a cookie was read from a file, it could accidentally strdup() a NULL
  pointer. Paul Harrington reported. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/cookie.c.diff?r1=1.25&r2=1.26]

- The MANUAL file now documents -t correctly. I also fixed the -T description
  in the curl.1 man page.

Daniel (29 October 2001)
- John Janssen found out that curl_formadd was missing in the libcurl.def file
  and that the docs stated the wrong return type for the function.

- Andrés García found a bug with multiple files in the curl_formadd() function,
  that I removed with this patch [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/formdata.c.diff?r1=1.25&r2=1.26].

- Kevin Roth brought another patch that moved the cygwin package files to the
  packages/Win32/cygwin directory.

- A bug in the connection re-use logic made repeated requests to the same FTP
  server (when using name+pasword in the URL) sometimes use more than one
  connection. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/url.c.diff?r1=1.166&r2=1.167]

- Moonesamy tracked down and fixed a problem with the new 7.9.1 connect
  code. This corrected the error Kevin Roth reported on the 7.9.1-pre5 release
  (test 19)...
  [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/connect.c.diff?r1=1.13&r2=1.14]

Daniel (26 October 2001)
- Added test28 which verifies that "Location:"-following works even if the
  contents is separated with more than one space.

Daniel (25 October 2001)
- Ramana Mokkapati pointed out that LDAP transfers would 'hang' after the
  correct data has been output.

Version 7.9.1-pre5

Daniel (24 October 2001)
- T. Bharath found a memory leak in the cookie engine. When we update a cookie
  that we already knew about, we lost a chunk of memory in the progress... The
  brand new test case 27 now tests for this occurrence. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/cookie.c.diff?r1=1.24&r2=1.25]

Daniel (23 October 2001)
- pack_hostent() didn't properly align some pointers, so at least SPARC CPUs
  would core. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/hostip.c.diff?r1=1.34&r2=1.35]

Daniel (22 October 2001)
- Tom Benoist reported that this SGI IRIX compiler didn't handle indented
  preprocessor instructions, so they're no longer in the source code!

- Applied Kevin Roth's patches to make it easier to build cygwin packages from
  the out-of-the-box curl release archives.

- I forgot to mention it below, but libcurl now closes connections that report
  transfer failures. Unconditionally. This could be made more nicely in the
  future if we set a flag or something that the connection is still good to be
  used for the errors that know that for a fact. We have to close the
  connection for the cases where we abort for example a HTTP transfer in the
  middle, or otherwise we might re-use that connection later with lots of data
  still being sent to us on it. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/transfer.c.diff?r1=1.63&r2=1.64]

Daniel (19 October 2001)
- CURLE_GOT_NOTHING is now returned when a HTTP server doesn't return
  anything, not even a header. test case 37 was added to test for this.

- T. Bharath made curl_easy_duphandle() properly clone the cookie status as
  well.

Version 7.9.1-pre4

Daniel (18 October 2001)
- CURLOPT_FAILONERROR, set with "curl --fail" no longer returns an error if
  the HTTP return code is below 400.

Daniel (17 October 2001)
- The test suite now kills any running test http server when you re-start the
  tests.

- We had to remove 'use strict' from two perl scripts, as the cygwin
  adjustments didn't play nicely otherwise for some reason. Any perl wizard
  out there who can put the scrict back and still make it run good on unix and
  cygwin?

- A potential memory leak pointed out to us by Yanick Pelletier was removed.
  It would occur when a http file transfer fails. [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/curl/curl/lib/transfer.c.diff?r1=1.60&r2=1.61]

- The memory debugging system should no longer display anything to stderr
  if the curl_memdebug() hasn't been used to explicitly say so. This makes it
  easier to use the memory debug system and switch the logging on/off.

Daniel (16 October 2001)
- Kevin Roth provided fixes for building curl nicer in cygwin environments.

Daniel (12 October 2001)
- Cleaning up the progress meter/info code. The "current speed" is now more
  accurate than before as we now use the true time spent between the measures,
  and not just "assuming" every-second-update like before. The output should
  now also be of the same width at all times, never to show "extra" zeroes on
  the right edge.

- After talking about possible Location: bugs on the mailing list, I modified
  the "absolute URL" checker in lib/transfer.c to be more strict when checking
  if the redirected URL is absolute.

Daniel (11 October 2001)
- Kevin Roth provided patches that make the test suite run fine on Windows
  2000 running cygwin.

Daniel (10 October 2001)
- Setting the -c or the CURLOPT_COOKIEJAR option now enables the cookie parser.
  Previously -b or CURLOPT_COOKIEFILE was also required for the jar to work.

Version 7.9.1-pre3

Daniel (9 October 2001)
- Added a new option to the command line client: -0/--http1.0. It uses the new
  libcurl option CURLOPT_HTTP_VERSION to request that libcurl uses HTTP 1.0
  requests instead of the default version (1.1). It should only be used if you
  really MUST do that because of a silly remote server.

- Renamed the 'TimeCond' typedef in curl/curl.h to use a 'curl_' prefix as
  all public curl-symbols should.

- libcurl now explicitly ignores the SIGPIPE signal.

Daniel (8 October 2001)
- Kevin Roth's change to the cookie-jar comment (in the stored file) was
  applied.

- Lucas Adamski's minor bug in the bind error code failf() was fixed.

Daniel (5 October 2001)
- Moonesamy fixed the Curl_connecthost() function to not give compiler errors
  on a bunch of compilers, due to the argument named 'socket'.

- Moonesamy also provided updated VC++ makefiles and project files.

Version 7.9.1-pre2

Daniel (4 October 2001)
- Albert Chin provided a configure patch that makes the script detect proper
  gethostbyname_r() method without actually running any code, only compiling
  is necessary. This also removes the need of having a resolving 'localhost'
  name.

- Found and removed memory leakage (name resolve data) in libcurl on
  IPv6-enabled hosts. These could sneak through because we didn't have any
  resource tracing on the IPv6-related functions. We do now.

Daniel (3 October 2001)
- Keith McGuigan patched away a (mainly Windows-) problem with the name
  resolver data being kept in the static memory area, which is removed when a
  thread is killed. The curl handle itself though perfectly handles being
  passed between threads.

- Dirk Eddelbuettel reported an odd bug that turned out to be his proxy that
  required an Authorization: header. Now, proxies are not supposed to require
  that header, that is for true servers...

- I accidentally ruined Georg's curl_formadd(). Uh, bad me. Corrected now.

Version 7.9.1-pre1

Daniel (3 October 2001)
- Georg Huettenegger once again made an effort beyond the call of duty and not
  only improved the curl_formadd() function, but also took care of adjusting
  the curl command line client to use this new function instead of the
  obsoleted curl_formparse.

Daniel (2 October 2001)
- Major fix in how libcurl does TCP connects. It now does non-blocking
  connects to enable good timeouts without signals, and it now tries all IP
  addresses for any given host (if it resolves more than one and the first
  one(s) don't connect). Added a new source file 'connect.c' to deal with all
  the TCP connect stuff.

- We now support IPv4-style IP-addresses in rfc2732-format, to better support
  people writing scripts without knowing what address there is.

Daniel (28 September 2001)
- Cleanups in the FTP source code. Divided the code into even more smaller
  functions and generally tried to make the differences between IPv4 and IPv6
  get less noticable in the sources.

- If the remote file time is not readable/accessable/understood by libcurl,
  libcurl now returns -1 in the CURLINFO_FILETIME data, not 0 as it previously
  did. This should make curl not touch the file data unless there was a known
  remote date when -R is used.

Daniel (27 September 2001)
- Working on getting non-blocking connects working platform independent. We
  will also make curl try all IPs for a given host if the first one should
  fail.

Daniel (26 September 2001)
- Kevin Roth provided a cookie example that proved the cookie jar
  functionality wasn't working properly. I added test case 46 and made it
  work.

Daniel (25 September 2001)
- Jörn Hartroth updated the mingw32 makefiles.

Version 7.9

Daniel (23 September 2001)
- Found and removed a 'socket leak' that would occur on IPv6 enabled hosts
  when FTP RETR failed.

- Made the FTP upload tests run fine on machines with IPv6 enabled.

Version 7.9-pre8

Daniel (19 September 2001)
- Vojtech Minarik set up a special-purpose test server and provided me with
  test certificates in order for me to repeat the bug reports #440068 and
  #440373. It turned out we didn't check all the error codes properly. We do
  now, and connecting with a unacceptable certificate will make libcurl fail
  to connect with an error code returned.

- Ramana Mokkapati found a case when the Location: following code did wrong.
  I wrote a test case for this (45).

Version 7.9-pre7

Daniel (17 September 2001)
- Linus Nielsen Feltzing fixed telnet for win32. It makes libcurl require
  winsock 2.0.

Version 7.9-pre6

- libtool 1.4.2 is now in use!

Version 7.9-pre5

Daniel (14 September 2001)
- Added another 14 ftp tests.

Daniel (13 September 2001)
- Added curl_easy_duphandle() to the easy.h header file. It has now been
  tested and proved to work in a real-world tests by T Bharath. We still need
  to write up some docs for this function.

- Added four more ftp tests to the test suite.

Daniel (12 September 2001)
- CURLOPT_SSL_CIPHER_LIST was added, and the curl tool option is named
  --ciphers. Use them to specify a list of ciphers to use in the SSL
  connection.

- T. Bharath found a memory leak in libcurl's windows version. It turned out
  to be the new duphandle() that didn't quite work yet.

Version 7.9-pre4

Daniel (11 September 2001)
- Added verbose output for SSL connections that output the server
  certificate's start and expire dates. As suggested by Paul Harrington.

- Heikki Korpela found problems in the perl ftp server used for the test
  suite, when he runs on on OpenBSD with perl 5.6. Some changes have been
  made, but nothing really certain.

- T. Bharath has experienced problems with libcurl's stack usage on windows
  and works on reducing it.

Daniel (10 September 2001)
- Cris Bailiff fixed the perl interface. It stopped working since the changed
  behavior with WRITEHEADER and NULL pointers.

- The "output cookies" function could dump core if no cookies were enabled.

Daniel (7 September 2001)
- SM pointed out that the SSL code didn't compile any longer if SSL was
  disabled... Also, we needed to correct the #include for the utime stuff on
  windows.

Daniel (6 September 2001)
- T. Bharath pointed out a flaw in the SSL session cache code that made it
  sometimes read from a NULL pointer.

Version 7.9-pre3

Daniel (3 September 2001)
- Added the -R/--remote-time option, that uses the remote file's datestamp to
  set the local file's datestamp. Thus, when you get a remote file your local
  file will get the same time and date. Note that this only works when you use
  -o or -O.

- Installed libtool 1.4.1, libtoolized and everything.

Daniel (1 September 2001)
- Heikki Korpela pointed out that I did not ship the proper libtool stuff in
  the pre-releases, even though that was my intention. libtoolize has now
  been re-run.

- Heikki also patched away the bad use of 'make -C' in the test suite
  makefile. make -C is not very portable and is now banned from here.

Version 7.9-pre2

Daniel (31 August 2001)
- I just made a huge internal struct rehaul, and all the big internally used
  structs have been renamed, redesigned and stuff have been moved around a bit
  to make the source easier to follow, more logically grouped and to hopefully
  decrease future bugs. I also hope that this will make new functions to get
  easier to add, and make it less likely that we have bugs left like the URL-
  free bug from August 23.

Version 7.9-pre1

Daniel (29 August 2001)
- The new cookie code have enabled the brand new '-c/--cookie-jar' option. Use
  that to specify the file name in which you want to have all cookies curl
  knows of, dumped to. It'll be written using the netscape cookie format.

  This is internally done with the new CURLOPT_COOKIEJAR option to libcurl,
  which in turn dumps this information when curl_easy_cleanup() is invoked.
  There might be reasons to re-consider my choice of putting it there. Perhaps
  it is better placed to get done just before *_perform() is done. It is all
  of course depending on how you guys want to use this feature...

- Added ftpupload.c in the source examples section, based on source code posted
  by Erick Nuwendam.

Daniel (28 August 2001)
- Now running libtool CVS branch-1-4 to generate stuff. Should fix problems
  on OpenBSD and hopefully on FreeBSD as well!

- Georg Huettenegger modified the curl_formadd() functionality slightly, and
  added support for error code 417 when doing form post and using the Expect:
  header. Great work!

- Made some tests with cached SSL session IDs, and they seem to work. There
  should be a significant speed improvement in the SSL connection phase, but
  in my tiny tests it just isn't possible to notice any difference. Like other
  caching in libcurl, you must reuse the same handle for the caching to take
  effect. SSL session ID caching is done on a per host-name and destination
  port number basis.

  Set verbose, and you'll get informational tests when libcurl detects and
  uses a previous SSL session ID.

- Upgraded to automake 1.5 on my development/release machine.

Daniel (27 August 2001)
- Slowly started writing SSL session ID caching code

Daniel (24 August 2001)
- T. Bharath removed compiler warnings on windows and updated the MS project
  files.

- Kevin Roth reported two kinds of command line constructs with the new -G that
  curl didn't really deal with the way one would like.

- Tim Costello patched away a use of strcasecmp() in the SSL code. We have our
  own portable version named strequal() that should be used!

- Tim also pointed out a problem in the lib/Makefile.vc6 file that made it mix
  debug object modules causing confusions.

Daniel (23 August 2001)
- T. Bharath accurately found a libcurl bug that would happen when doing a
  second invoke of curl_easy_perform() with a new URL when the previous invoke
  followed a Location: header.

- Started the improvement work on the cookie engine:
  - Now keeps cookies in the same order as the cookie file
  - A write to the possibly static string was removed
  - Added a function that can output all cookies
  - Now supports reading multiple cookie files

- Steve Lhomme corrected a DLL naming issue in the MSVC++ project file.

- Split up the monster function in lib/ftp.c to use more smallish functions to
  increase readability and maintainability.

Daniel (21 August 2001)
- Georg Huettenegger's big patch was applied. Now we have:
  o "Expect: 100-continue" support. We will from now on send that header in
    all rfc1867-posts, as that makes us abort much faster when the server
    rejects our POST. Posting without the Expect: header is still possible in
    the standard replace-internal-header style.
  o curl_formadd() is a new formpost building function that is introduced to
    replace the now deprecated curl_formparse() function. The latter function
    will still hang around for a while, but the curl_formadd() is the new way
    and correct way to build form posts.
  o Documentation has been updated to reflect these changes

  These changes are reason enough to name the next curl release 7.9...

- We now convert man pages to HTML pages and include them in the release
  archive. For the pleasure of everyone without nroff within reach.

- Andrés García's suggested flushing of the progress meter output stream was
  added. It should make the progress meter look better on Windows.

- Troy Engel pointed out a mistake in the configure script that made it fail
  on many Red Hat boxes!

Daniel (20 August 2001)
- We need an updated libtool to make a better build environment for OpenBSD
  as well as FreeBSD

Version 7.8.1

Daniel (20 August 2001)
- Brad pointed out that we ship two extra libtool files in the tarballs that
  we really don't need to! Removing them makes the gz-archive about 60K
  smaller!

- Albert Chin brought fixes for the configure script to detect socklen_t
  properly as well as moving lots of our custom autoconf macros to
  acinclude.m4.

Daniel (19 August 2001)
- Moonesamy improved his -G feature for host names only URLs...

Daniel (17 August 2001)
- Finally cleaned up the kerberos code to use Curl_ prefixes on all global
  symbols and to not use global variables.

Version 7.8.1-pre6

Daniel (16 August 2001)
- S. Moonesamy added the -G option to curl, that converts the data specified
  with -d to a GET request. Default action when using -d is POST. When -G is
  used, the -d specified data will be appended to the URL with a '?'
  separator. As suggested previously by Kevin Roth.

- curl-config --libs should now display all linker options required to link
  with libcurl. It includes the path and options for libcurl itself.
  curl-config --cflags displays the compiler option(s) needed to compile
  source files that use libcurl functions. Basically, that sets the include
  path correct.

Daniel (15 August 2001)
- Arkadiusz Miskiewicz pointed out a mistake in how IPv6-style IP-addresses
  were parsed and used. (RFC2732-format)

- Bug #12733 over on php.net identified a problem in libcurl that made it core
  dump if you used CURLOPT_POST without setting any data to post with
  CURLOPT_POSTFIELDS! This is no longer the case. Not using CURLOPT_POSTFIELDS
  now equals setting it to no data at all.

- Ramana Mokkapati reported that curl with '-w %{http_code}' didn't work
  properly when used for multiple URLs on a single command line. Indeed, the
  variable was not reset between the requests. This is now fixed.

- David James fixed the Borland makefile so that libcurl still compiles and
  builds with that compiler.

Daniel (14 August 2001)
- Oops. I ruined Nico's socklen_t define in config-vms.h, corrected it now.

- An older item not mentioned here before: CURL_GLOBAL_WIN32 is a define for
  windows users to curl_global_init(), that makes libcurl init the winsock
  stuff. If libcurl is all socket stuff you do, then allowing it to fiddle
  with this is a comfortable shortcut to fame.

Version 7.8.1-pre5

Daniel (14 August 2001)
- Nico Baggus provided more feedback from his VMS porting efforts and a few
  minor changes were necessary.

- I modified configure.in so that --enable-debug sets more picky gcc options.
  I then removed almost all the new warnings that appeared, and by doing so I
  corrected the size_t-treated-as-signed problem that has been discussed on
  the mailing list previously. I also removed a bunch of the just recently
  added #ifdef VMS lines.

- I removed the use of a global variable in the SSL code. It was once
  necessary but hasn't been needed since OpenSSL 0.9.4. The old code should
  (hopefully) still work if libcurl is built against an ancient version of
  OpenSSL.

Daniel (13 August 2001)
- Peter Todd posted a patch that now allows non-file rc1867-style form posts
  to be larger than 4K.

Daniel (10 August 2001)
- S. Moonesamy fixed bugs for building debug and SSL lib in VC makefile

Daniel (9 August 2001)
- The redirected error stream was closed before the curl_easy_cleanup() call
  was made, and when VERBOSE was enabled, the cleanup function tried to use
  the stream. It could lead to a segmentation fault. Also, the stream was
  closed even if we looped to get more files.  Corrects Dustin Boswell's bug
  report #441610

- Now generates the release configure script with autoconf 2.52

Version 7.8.1-pre4

Daniel (8 August 2001)
- curl -E uses a colon to separate a file name from a passphrase. This turned
  out really bad for the windows people who wants to include a drive letter in
  the file name like "c:\cert.pem". There's now a win32 work-around
  implemented that tries work around that, when the colon seems to be used for
  this kind of construct.

- Patrick Bihan-Faou introduced CURLOPT_SSL_VERIFYHOST, which makes curl
  verify the server's CN field when talking https://. If --cacert is not used,
  any failures in matching is only displayed as information (-v).

Daniel (7 August 2001)
- Wrote up nine more test cases, more or less converted from the former test
  suite.

Daniel (6 August 2001)
- Heikki Korpela posted a patch that makes 'curl-config --libs' include the
  directory in which libcurl itself is installed in. While this wasn't my
  initial intention with this option, it makes sense and makes linking with
  libcurl easier.

- Stefan Ulrich pointed out to us that other tools and libraries treat file://
  URLs with only one slash after the host name slighly different than libcurl
  does. Since all the others seem to agree, we better follow them.

- Nico Baggus provided us with a huge set of fixes to make curl compile and
  build under OpenVMS.

Version 7.8.1-pre3

Daniel (6 August 2001)
- Jonathan Hseu noticed that you couldn't get a header callback unless you
  set CURLOPT_WRITEHEADER to non-NULL, even if you didn't care about that
  data. This is now fixed.

Daniel (5 August 2001)
- Sergio Ballestrero provided a patch for reading responses from NCSA httpd
  1.5.x servers, as they return really screwed up response headers when asked
  for with HTTP 1.1.

- curl_escape() no longer treats already encoded characters in the input
  string especially.

Daniel (3 August 2001)
- I replaced the former lib/arpa_telnet.h file with one I wrote myself, to
  avoid the BSD annoucement clause of the license in the former file.

- Andrew Francis provided a new version of base64.c to work around the license
  boiler plate that came with the previous one. I patched it, but the glory
  should go to Andrew for his heads up.

- Tomasz Lacki noticed that when you do repeated transfers with libcurl you
  couldn't always reliably change HTTP request. This has now been fixed and a
  new libcurl option was added: CURLOPT_HTTPGET, that can force the HTTP
  requestr (back) to GET.

- Linus Nielsen Feltzing pointed out that httpsserver.pl wasn't included in
  release archives. It should be now.

Daniel (2 August 2001)
- Frank Keeney pointed out a manual mistake for certificate convertions.

- Tomasz Lacki pointed out a problem in the transfer loop that could make the
  select() loop use far too much CPU.

- Pawel A. Gajda pointed out an output mistake done when using libcurl's
  progress callback.

Daniel (29 June 2001)
- Naveen Noel noticed that the Borland library makefile wasn't updated.

- Nic Roets brought a fix for the certificate verification when using SSL.

Daniel (27 June 2001)
- Made the FTP tests run OK even on machines running curl IPv6-enabled.

- Troy Engel corrected some RPM package details.

Version 7.8.1-pre2

Daniel (25 June 2001)
- Björn Stenberg correctly identified a problem that occurred when downloading
  several files with curl, and using resume. The first file's resume index was
  then used for all files, resulting in weird results...

- Anton Kalmykov provided a fix that makes curl work with form field names
  with spaces like when -F is used.

Version 7.8.1-pre1

Daniel (20 June 2001)
- Mike Bytnar provided a fine report that proved that the --with-ssl option
  for configure needed tweaking. It no longer searches the default directories
  for OpenSSL libs or directories when a specified path is given.

Daniel (19 June 2001)
- When an FTP transfer is cut off during transfer, curl could present a truly
  garbaged error message and in worst case dump core. Thanks to detailed
  reports from Shawn Poulson we nailed this.

Daniel (12 June 2001)
- Salvador Dávila provided a fix for FTP range downloads.

- Added a few more test cases from the former test suite to the new file
  format. We're now at a total of 26 tests.

Daniel (11 June 2001)
- libcurl's version-info was wrong, as noted by both Domenico Andreoli and
  David Odin.

Daniel (7 June 2001)
- Jörn fixed the curl_unescape duplicate entry in lib/libcurl.def

- I made SSL certificate failure messages to be more detailed.

Version 7.8

Daniel (7 June 2001)
- SDavila provided a resumed download fix.

Version 7.8-pre4

Daniel (1 June 2001)
- Sterling provided some new PHP examples.

- Changed the CVS hierarchy and the older checkout instruction does no longer
  work. We moved the entire source code into a CVS module named 'curl'.

Daniel (31 May 2001)
- CURLOPT_MUTE does not exist anymore. It is still present in the include file
  to not cause compiler errors for applications using it, but it isn't used
  anywhere in the library.

Version 7.8-pre3

Daniel (31 May 2001)
- Once and for all fixed the _REENTRANT mess for Solaris compiles to present
  less warnings.

- Sterling Hughes tirelessly points out and corrects my mistakes...! So,
  curl_global_init() now lets the argument flags *SET* what parts to
  init. CURL_GLOBAL_DEFAULT makes a nice default, CURL_GLOBAL_ALL inits all
  known subsystems and CURL_GLOBAL_NONE inits nothing more than absolutely
  necessary. Man page updated accordingly.

- Fixed the strtok.h include file as it wouldn't compile on all platforms!

Daniel (30 May 2001)
- Made libcurl by default act as if CURLOPT_MUTE and CURLOPT_NOPROGRESS were
  set TRUE. Set them to FALSE to make libcurl more talkative. The *_MUTE
  option is subject for complete removal...

Version 7.8-pre2

Daniel (30 May 2001)
- Cris Bailiff wrote a makefile for building Solaris packages.

- Sterling Hughes brought fixes for 'buildconf' (the build-from-CVS tool) and
  we discussed and added a few CURL_GLOBAL_* flags in include/curl.h

- Kjetil Jacobsen privately announced his python interface to libcurl,
  available at http://pycurl.sourceforge.net/

Daniel (29 May 2001)
- Sterling Hughes fixed a strtok() problem in libcurl. It is not a thread-
  safe function. Now configure checks for a thread-safe version, and
  lib/strtok.c offers one for the systems that don't come with one included!

- Mettgut Jamalla correctly pointed out that the -# progress bar was written
  to stderr even though --stderr redirection was used. This is now corrected.

- I moved out the list of contributors from the curl.1 man page and made a
  separate docs/THANKS file. It makes the list easier to find, and made it
  easier for me to make a separate web page with that same information.

  I really do want all you guys mentioned in there to feel you get the credit
  you deserve.

- lib/easy.c didn't compile properly in the 7.8-pre1 due to a silly mistake

Version 7.8-pre1

Daniel (28 May 2001)
- curl-config now supports '--vernum' that outputs a plain hexadecimal version
  of the libcurl version number (using 8 bits for each 3 numbers). Version
  7.7.4 appears as 070704

- Wrote man pages for curl_global_init and curl_global_cleanup...

- T. Bharath brought news about the usage of the OpenSSL interface that was
  not previously taken into consideration and thus caused libcurl to leak
  memory.  The only somewhat sane approach to fix this dilemma, is adding two
  two new functions curl_global_init() and curl_global_cleanup() that should
  be called *ONCE* by the application using libcurl. The init should be done
  only at startup, no matter how many threads the application is gonna use,
  and the cleanup should be called when the application has finished using
  libcurl completely.

  *** UPGRADE NOTICE ***

  If you write applications using libcurl, you really want to use the two
  functions mentioned above !!!

  I can't say I think this is a very beautiful solution, but as OpenSSL
  insists on making lots of stuff on a "global" scope, we're forced to walk
  the path they point us to.

- Moving more test cases into the new file format.

Version 7.7.4-pre3

Daniel (23 May 2001)
- Introduced a new file format for storing test cases, and thus I had to
  modify all the perl test scripts and more (I added a new one). I have not
  "ported" all the old test cases to the new format yet, but it'll come.

  The main advantage of this new format is that all test data for each test
  case is stored in a single file. It gives a better overview for each test
  case and a lot less files.

- Andrés García brought a fix for the netscape/mozilla cookie file parsing
  function, as it turns out it doesn't always store the path!

Daniel (22 May 2001)
- As was reported anonymously, when FAILONERROR was used, the httpcode was
  not stored properly and thus wasn't possibly to read after a transfer with
  the curl_easy_getinfo() function. This is now corrected.

- Installed and made use of the following tool versions:
    autoconf 2.50
    libtool 1.4
    automake 1.4-p1

  I wouldn't recommend any developer to try to generate things with older
  versions than these. Building from CVS will probably more or less require
  at least these versions.

  As a result of this, the configure script grew to more than double its
  previous size!

  Arkadiusz Miskiewicz helped me by pointing out I had to remove my
  acinclude.m4 file before I could get it working!

Daniel (21 May 2001)
- I made ftps:// work. Added test case 400 to the release archive, as the
  first ftps:// test case. Requires stunnel.

- Also made the test cases that runs ssl tests not run if libcurl isn't built
  with ssl support.

Daniel (19 May 2001)
- Made the configure not add any extra -L LDFLAGS or -I CPPFLAGS unless they
  are actually needed. Albert Chin's and Domenico Andreoli's suggestions
  helped out.

Version 7.7.4-pre2

Daniel (18 May 2001)
- Nicer configure-check for the OpenSSL headers, which then sets the proper
  variable to have curl-config be good. (Albert Chin provided the fix)

- For systems that don't have theiw own 'strlcat()' libcurl provides its own.
  It was now renamed to prevent collides with other libs. (After discussions
  with Sterling Hughes and the implications this had on PHP builds.)

Daniel (17 May 2001)
- Colm Buckley posted a detailed bug report on (the debianized) 7.7.3, that
  turned out to be a problem with the debian-built 7.7.3-package that
  contained files from the 7.7.2 release!

- I added the CURLE_ALREADY_COMPLETE again, but with a fake value, just to
  make programs that use it, not fail when compiling against this version of
  libcurl.

Daniel (14 May 2001)
- Pawel A. Gajda fixed a problem with resumed transfers on re-used persistent
  connections.

Version 7.7.4-pre1

Daniel (14 May 2001)
- Jun-ichiro itojun Hagino fixed FTP PORT for IPv6-enabled libcurl.

- Added the first HTTPS test to the test suite in the release archive.

Daniel (12 May 2001)
- Jukka Pihl suggested that if (lib)curl is told to verify the peer's
  certificate and the peer can't be verified, it should fail and return a
  proper error code. I added a brand new error code named
  CURLE_SSL_PEER_CERTIFICATE for this purpose.

Daniel (11 May 2001)
- As was discussed with Frederic Lepied a while ago, I now made libcurl not
  return error even though no data was transfered on upload/download resume
  when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
  from the header file to make any implemenator that uses that to be aware of
  the fact that it can't be returned anymore!

- Improved general header-parsing to better allow white spaces and more.

- Rodney Simmons proved the fix I did yesterday was bad and I had to post
  another one.

- Ingo Wilken patched away two redirect problems more!

Daniel (10 May 2001)
- Cris Bailiff correctly noted that the space-after-header problem with
  Location: is present on several other places in the libcurl sources.

- Ingo Wilken patched away a problem libcurl had when following Location:
  headers with an extra space after the colon.

- Rodney Simmons found out that multiple FTP transfers did not treat relative
  directories correctly.

Daniel (9 May 2001)
- Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
  makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
  returned error. Starting now, it just don't output the file size instead.
  Anonymous bug report.

- stunnel.pm was accidentally left out from the release archive, it is now
  added (stunnel is needed to run the https-tests in the test suite)

Daniel (7 May 2001)
- Corrected two minor compiler warnings due to the FILE * to void * conversion
  that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
  filed a bug report on this.

Version 7.7.3

Daniel (4 May 2001)
- All callback functions now take 'void *' instead of 'FILE *'. This is made
  this way to make it more obvious to people that anything can be passed to
  them (by using the apropriate option). After discussions with Sterling
  Hughes.

Daniel (3 May 2001)
- Cris Bailiff fixed a chunked transfer encoding problem with persistent
  connection that made libcurl fail if the persistent connection used mixed
  chunked and non-chunked transfers.

- Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
  treated as content-length 0 replies but would cause a "hang" until the
  server timed-out and closed the connection.

- Brad Burdick found a minor problem in the docs/examples/Makefile.am

Daniel (27 April 2001)
- Updated the INTERALS document again. It was lagging a bit. I think I made it
  more easy to follow now as well.

- Brad Burdick found a problem with persistent connections when curl received
  a "Content-Length: 0" header.

- Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
  compiled/built on win32. It seems to work for unixes though!

- Dave Hamilton reported weird problems with CURL/PHP that I really can't
  explain at the moment. I'm hoping on some help from the PHP crew.

Daniel (26 April 2001)
- I rewrote the FTP command response function. I had to do it to make ftps
  work, as the OpenSSL read()-function didn't work the same way the normal
  unix read() does, but it was also a huge performance boost. Previously the
  function read one byte at a time, now it reads very large chunks, and it
  makes a notable speed difference.

Daniel (25 April 2001)
- Connection re-use when not using a proxy didn't work properly for
  non-default port numbers.

Daniel (24 April 2001)
- I've noticed that FTPS doesn't work. We attempt to use ssl even for the
  data transfer, which causes the transfer to 'hang'... We need to fix this.

- Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
  the alredy written perl servers easily.

Daniel (23 April 2001)
- The OpenSSL version string recently modified didn't zero terminate one
  of the generated strings properly, which could lead to a crash or simply
  weird version string output!

Version 7.7.2

Daniel (22 April 2001)
- Rosimildo da Silva updated the Makefiles for Borland/Windows.

- Eric Rautman pointed out a problem with persistent connections that would
  lead to broken Host: headers in the second HTTP request.

Daniel (20 April 2001)
- Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
  a 'libcurl overview' man page.

- Spell-fixed some documents.

- S. Moonesamy corrected mistakes in the man page.

- Cris Bailiff fixed the curl_slists options in the perl interface, present
  separately in the Curl::easy 1.1.4 package.

Daniel (19 April 2001)
- Linus Nielsen Feltzing removed the decimals from the size variables in the
  --write-out output. We hardly ever get fraction of bytes! :-)

Version 7.7.2-pre1

Daniel (19 April 2001)

- Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.

Daniel (18 April 2001)
- Input from Michael Mealling made me add --feature to curl-config. It
  displays a list of features that have been built-in in the current
  libcurl. The currently available features that can be listed are: SSL, KRB4
  and IPv6.

- I committed Cris and Georg's perl interface work. They've got callbacks
  working and options that receives those slist pointers.

- Puneet Pawaia detected a problem with resumed downloads that use persistent
  connections and I made a rather large writeup to correct this. It is
  important that all session-data is stored in the connectdata struct and not
  in the main struct as this previously did.

Daniel (17 April 2001)
- Frederic Lepied fixed a ftp resumed download problem and introduced a new
  error code that lets applications be able to detect when a resumed download
  actually didn't download anything since the whole file is already present.
  Should this return OK instead?

- I added 'curl-config.in' to the root dir and configure script. Now, a
  curl-config script is made when curl is built. The script can be used to
  figure out compile time options used when libcurl was built, which in turn
  should be options YOU should use to build applications that use libcurl.

  This *-config style is not a new idea, but something that has been used
  successfully in other (library based) projects.

- Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
  for the If-Modified-Since style headers.

- Georg Schwarz pointed out an extra needed #include file needed in src/main.c
  for curl to build on Ultrix.

Daniel (11 April 2001)
- Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
  of the environment variable HTTP_PROXY in uppercase may become a security
  hazard when people use libcurl in a server/cgi situation where the server
  sets the HTTP_*-variables according to incoming headers in the HTTP
  request. Thus, a "Proxy:"-header would set that environment variable!

  Then, invoking curl_easy_perform() without having an URL set caused a crash.

- S. Moonesamy brought a patch that make curl use non-blocking connects on
  windows when connection timeout is set, as it allows windows users to set
  that timeout!

- Hirotaka Matsuyuki wrote a Ruby interface to libcurl!

- Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.

- I've written a first shot at a Java interface to libcurl. Many thanks to
  Daniel Marell for tirelessly answering to all my basic Java questions. It
  works, but it is still very basic.

Daniel (10 April 2001)
- The progress display could get silly when doing multiple file transfers, as
  it wasn't properly reset between transfers!

- Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
  me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
  function for writing headers. Previously you could only set a different FILE
  * when headers are written from within libcurl.

Daniel (7 April 2001)
- Andrés García fixed a problem in curl_escape() and pointed out a flaw in
  the curl_easy_setopt man page.

Daniel (6 April 2001)
- Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
  change their version define format often...

- curl_formfree() now accepts a NULL pointer without crashing!

Version 7.7.1

Daniel (3 April 2001)
- Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
  read bad memory during situations when an (ftp) connection attempt failed.
  Also, the lib/Makefile.vc6 was corrected.

- More investigations in the Location: following code made me realize that
  it was not clean enough to work transparantly with persistent and non-
  persistent connections. I think I've fixed it now.

Daniel (29 March 2001)
- Georg Horn mailed me some corrections for the Curl::easy perl interface.

- Experimental ftps:// support added. It is basically FTP over SSL for the
  control connection. It still makes all data transfers going over unencrypted
  connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
  that to verify the functionality.

Daniel (27 March 2001)
- Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
  to get a file from a site and it fails, the SIGALRM would still be sent
  after the timeout-time, quite inexpectedly!

- I added an ftp transfer example to docs/examples/ and I also wrote a tiny
  example makefile that can be used as a start when building one of the
  examples.

Version 7.7.1-beta1

Daniel (26 March 2001)
- Mohamed Lrhazi reported problems with 7.6.1 and persistent HTTP/1.0
  connections (when the server replied a Connection: Keep-Alive) and this
  problem was not properly dealt with in 7.7 either. A patch was posted to the
  curl-and-php mailing list.

Daniel (24 March 2001)
- Colin Watson reported about a problem and brought a patch that corrected it,
  which was about the man page and lines starting with a single quote (') in a
  way that gnroff doesn't like.

Daniel (23 March 2001)
- Peter Bray reported correctly that the root makefile used make instead of
  $(MAKE) for the test target.

- Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
  curl_setopt() which was removed in 7.7!

- S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).

- When following a Location:, libcurl would sometimes write to the URL string
  in a way it shouldn't. As the pointer is passed-in to libcurl from an
  application, we can't be allowed to write to it. The particular bug report
  from 'nk' that brought this up was because he had a read-only URL that then
  caused a libcurl crash!

- No longer reads HEAD responses longer than to the last header. Previously,
  curl would read the full reply if the connection was a "close" one.

- libcurl did re-use connections way too much. Doing "curl
  http://www.{microsoft,ibm}.com" would make it re-use the connection which
  made the second request return very odd results.

Daniel (22 March 2001)
- Edin Kadribasic made me aware that curl should not re-send POST requests
  when following 302-redirects. I made 302 work like 303 which means curl uses
  GET in the following request(s).

- libcurl now reset the "followed-location" counter on each invoke of
  curl_easy_perform() as it otherwise would sum up all redirects on the same
  connection and thus could reach the maxredirs counter wrongly.

- Jim Drash suggested curl_escape() should not re-encode what already looks
  like an encoded sequence and I think that's a fair suggestion.

Version 7.7

Daniel (22 March 2001)
- The configure script now fails with an error message if gethostbyname_r() is
  detected but it couldn't figure out how to invoke it (what amount of
  arguments it is supposed to get). Reports from Andrés García made me aware
  of this need.

- Talking with Jim Drash made me finally put the curl_escape and curl_unescape
  functions in the curl.h include file and write man pages for them. The
  escape function was modified to use the same interface as the unescape one
  had.

- No bug reports at all on the latest betas. Release time coming up.

Version 7.7-beta5

Daniel (19 March 2001)
- Georg Ottinger reported problems with using -C together with -L in the sense
  that the -C info got lost when it was redirected. I could not repeat this
  problem on the 7.7 branch why I leave this for the moment. Test case 39 was
  added to do exactly this, and it seems to do right.

- Christian Robottom Reis reported how his 7.7 beta didn't successfully do
  form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
  engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
  and POST operations that I need to add support for. Section 8.2.3 in RFC2616
  has all the details. Seems to work now!

Daniel (16 March 2001)
- After having experienced another machine break-down, we're back.

- Georg Horn's perl interface Curl::easy is now included in the curl release
  archive. The perl/ directory is now present. Please help me with docs,
  examples and updates you think fit.

- Made a new php/ directory in the release archive and moved the PHP examples
  into a subdirectory in there. Not much PHP info yet, but I plan to. Please
  help me here as well!

- Made libcurl return error if a transfer is aborted in the middle of a
  "chunk". It actually enables libcurl to discover premature transfer aborts
  even if the Content-Length: size is unknown.

Daniel (15 March 2001)
- Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
  option in libcurl. It limits the time curl is allowed to spend in the
  connection phase. This differs from -m/--max-time that limits the entire
  file transfer operation. Requested by Larry Fahnoe and others.

  I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
  item from the TODO.

Version 7.7-beta4

Daniel (14 March 2001)
- Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
  again when ENABLE_IPV6 is set.

  I need to remake things in the test suite. I can't test the FTP parts with
  curl built for IPv6 as it uses a different set of FTP commands then!

- I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
  a report meant for our project. Anyway, it said the .netrc parsing didn't
  work as supposed, and as I agreed with Lars, I made the netrc parser use
  getpwuid() to figure out the home directory of the effective user and try
  that netrc. It still uses the environment variable HOME for those that don't
  have that function or if the user doesn't return valid pwd info.

- Edin Kadribaic posted a bug report where he got a crash when a fetch with
  user+password in the URL followed a Location: to a second URL (absolute,
  without name+password). This bug has been around for a long while and
  crashes due to a read at address zero. Fixed now. Wrote test case 38, that
  tests this.

- Modified the test suite's httpserver slightly to append all client request
  data to its log file so that the test script now better can verify a range
  of requests and not only the last one, as it did previously.

- Updated the curl man page with --random-file and --egd-file details.

Version 7.7-beta3

Daniel (14 March 2001)
- Björn Stenberg provided similar fixes as Jörn did and some additional patches
  for non-SSL compiles.

- I increased the interface number for libcurl as I've removed the low level
  functions from the interface. I also took this opportunity to rename the
  Curl_strequal function to curl_strequal and Curl_strnequal to
  curl_strnequal, as they're public libcurl functions (even if they're still
  undocumented).

  This will make older programs not capable of using the new libcurl with
  just a drop-in replacement.

- Jörn Hartroth updated stuff for win32 compiles:
  o config-win32.h was fixed for socklen_t
  o lib/ssluse.c had a bad #endif placement
  o lib/file.c was made to compile on win32 again
  o lib/Makefile.m32 was updated with the new files
  o lib/libcurl.def matches the current interface state

Daniel (13 March 2001)
- It only took an hour or so before Jörn Hartroth found a problem in the
  chunked transfer-encoding. Given his fine example-site, I could easily spot
  the problem and when I re-read the spec (the part I have pasted in the top
  of the http_chunks.h file), I realized I had made my state-machine slightly
  wrong and didn't expect/handle the trailing CRLF that comes after the data
  in each chunk (and those extra two bytes sure feel wasted).

  Had to modify test case 34 to match this as well.

Version 7.7-beta2

Daniel (13 March 2001)
- Added the policy stuff to the curl_easy_setopt man page for the two supported
  policies.

- Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
  CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
  supported, and the "least recently used" is used as default if no policy
  is chosen.

Daniel (12 March 2001)
- Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
  SSL random engine. The random seeding support was also brought to the curl
  client with the new options --random-file <file> and --egd-file <file>. I
  need some people to really test this to know they work as supposed. Remember
  that libcurl now informs (if verbose is on) if the random seed is considered
  weak (HTTPS connections).

- Made the chunked transfer-encoding engine detected bad formatted data length
  and return error if so (we can't possibly extract sensible data if this is
  the case). Added a test case that detects this. Number 36. Now there are 60
  test cases.

- Added 5 new libcurl options to curl/curl.h that can be used to control the
  persistent connection support in libcurl. They're also documented (fairly
  thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
  implemented, although not really tested at this point... Anyway, the new
  implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
  CURLOPT_FORBID_REUSE. The ones still left to write code for are:
  CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.

- Made curl (the actual command line tool) use the new libcurl 7.7 persistent
  connection support by re-using the same curl handle for every specified file
  transfer and after some more test case tweaking we have 100% test case OK.
  I made some test cases return HTTP/1.0 now to make sure that works as well.

- Had to add 'Connection: close' to the headers of a bunch of test cases so
  that curl behaves "old-style" since the test http server doesn't do multiple
  connections... Now I get 100% test case OK.

- The curl.haxx.se site, the main curl mailing list and my personal email are
  all dead today due to power blackout in the area where the main servers are
  located. Horrible.

- I've made persistance work over a squid HTTP proxy. I find it disturbing
  that it uses headers that aren't present in any HTTP standard though
  (Proxy-Connection:) and that makes me feel that I'm now on the edge of what
  the standard actually defines. I need to get this code excercised on a lot
  of different HTTP proxies before I feel safe.

  Now I'm facing the problem with my test suite servers (both FTP and HTTP)
  not supporting persistent connections and libcurl is doing them now. I have
  to fix the test servers to get all the test cases do OK.

Daniel (8 March 2001)
- Guenole Bescon reported that libcurl did output errors to stderr even if
  MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
  there's an error and no ERRORBUFFER is set. This is now corrected.

Version 7.7-beta1

Daniel (8 March 2001)
- "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
  added two source files and I've run some test downloads that look fine.

- HTTP HEAD works too, even on 1.1 servers.

Daniel (5 March 2001)
- The current 57 test cases now pass OK. It would suggest that libcurl works
  using the old-style with one connection per handle. The test suite doesn't
  handle multiple connections yet so there are no test cases for this.

- I patched the telnet.c heavily to not use any global variables anymore. It
  should make it a lot nicer library-wise.

- The file:// support was modified slightly to use the internal connect-first-
  then-do approach.

Daniel (4 March 2001)
- More bugs erased.

Version 7.7-alpha2

Daniel (4 March 2001)
- Now, there's even a basic check that a re-used connection is still alive
  before it is assumed so. A few first tests have proven that libcurl will
  then re-connect instead of re-use the dead connection!

Daniel (2 March 2001)
- Now they work intermixed as well. Major coolness!

- More fiddling around, my 'tiny' client I have for testing purposes now has
  proved to download both FTP and HTTP with persistent connections. They do
  not work intermixed yet though.

Daniel (1 March 2001)
- Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
  curl_slist_append() should take a const char * as second argument. It does
  now.

Daniel (22 February 2001)
- The persistent connections start to look good for HTTP. On a subsequent
  request, it seems that libcurl now can pick an already existing connection
  if a suitable one exists, or it opens a new one.

- Douglas R. Horner mailed me corrections to the curl_formparse() man page
  that I applied.

Daniel (20 February 2001)
- Added the docs/examples/win32sockets.c file for our windows friends.

- Linus Nielsen Feltzing provided brand new TELNET functionality and
  improvements:

  * Negotiation is now passive. Curl does not negotiate until the peer does.
  * Possibility to set negotiation options on the command line, currently only
    XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
  * Now sends the USER environment variable if the -u switch is used.
  * Use -t to set telnet options (Linus even updated the man page, awesome!)

- Haven't done this big changes to curl for a while. Moved around a lot of
  struct fields and stuff to make multiple connections get connection specific
  data in separate structs so that they can co-exist in a nice way. See the
  mailing lists for discussions around how this is gonna be implemented. Docs
  and more will follow.

  Studied the HTTP RFC to find out better how persistent connections should
  work. Seems cool enough.

Daniel (19 February 2001)
- Bob Schader brought me two files that help set up a MS VC++ libcurl project
  easier. He also provided me with an up-to-date libcurl.def file.

- I moved a bunch of prototypes from the public <curl/curl.h> file to the
  library private urldata.h. This is because of the upcoming changes. The
  low level interface is no longer being planned to become reality.

Daniel (15 February 2001)
- CURLOPT_POST is not required anymore. Just setting the POST string with
  CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
  libcurl already works this way, i.e they require only the parameter to
  switch on a feature so I think this works well with the rest. Setting a NULL
  string switches off the POST again.

- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
  Reese helped me define a way how to incorporate persistent connections into
  libcurl in a very smooth way. If done right, no change may have to be made
  to older programs and they will just start using persistent connections when
  applicable!

Daniel (13 February 2001)
- Changed the word 'timeouted' to 'timed out' in two different error messages.
  Suggested by Larry Fahnoe.

Version 7.6.1

Daniel (9 February 2001)
- Frank Reid and Cain Hopwood provided information and research around a HTTPS
  PUT/upload problem we seem to have. No solution found yet.

Daniel (8 February 2001)
- An interesting discussion is how to specify an empty password without having
  curl ask for it interactively? The current implmentation takes an empty
  password as a request for a password prompt. However, I still want to
  support a blank user field. Thus, today if you enter "-u :" (without user
  and password) curl will prompt for the password. Tricky. How would you
  specify you want the prompt otherwise?

- Made the netrc parse result possible to use for other protocols than FTP and
  HTTP (such as the upcoming TELNET fixes).

- The previously mentioned "MSVC++ problems" turned out to be a non-issue.

- Added a HTTP file upload code example in the docs/examples/ section on
  request.

- Adjusted the FTP response fix slightly.

Version 7.6.1-pre3

Daniel (7 February 2001)
- S. Moonesamy found a flaw in the response reading function for FTP that
  could make libcurl not get out of the loop properly when it should, if
  libcurl got -1 returned when reading the socket.

- I found a similar mistake in http.c when using a proxy and reading the
  results from the proxy connection.

Daniel (6 February 2001)
- S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
  for the debug build to work.

- Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
  brought up yesterday.

Daniel (5 February 2001)
- Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
  a bunch of different areas within libcurl.

- Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
  the 'static' keyword on a number of libcurl functions. I might need to add a
  patch that redefines static when libcurl is compiled with that compiler.
  How do I know when VC++ compiles, anyone?

Daniel (4 February 2001)
- curl_getinfo() was extended with two new options:
  CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
  return the full assumed content length of the transfer in the given
  direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
  size of a HTTP download. Added descriptions to the man page as well. This
  was done after discussions with Bob Schader.

Daniel (3 February 2001)
- Ingo Ralf Blum provided another fix that makes curl build under the more
  recent cygwin installations. It seems they've changed the preset defines to
  not include WIN32 anymore.

Version 7.6.1-pre2

Daniel (31 January 2001)
- Curl_read() and curl_read() now return a ssize_t for the size, as it had to
  be able to return -1. The telnet support crashed due to this and there was a
  possibility to weird behavior all over. Linus Nielsen Feltzing helped me
  find this.

- Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
  I also made the configure script feature --enable-debug which sets a couple
  of compiler options when used. It assumes gcc.

Daniel (30 January 2001)
- I finally took a stab at the long-term FIXME item I've had on myself, and
  now libcurl will properly work when doing a HTTP range-request that follows
  a Location:. Previously that would make libcurl fail saying that the server
  doesn't seem to support range requests.

Daniel (29 January 2001)
- I added a test case for the HTTP PUT resume thing (test case 33).

Version 7.6.1-pre1

Daniel (29 January 2001)
- Yet another Content-Range change. Ok now? Bob Schader checks from his end
  and it works for him.

Daniel (27 January 2001)
- So the HTTP PUT resume fix wasn't good. There should appearantly be a
  Content-Range header when resuming a PUT.

- I noticed I broke the download-check that verifies that a resumed HTTP
  download is actually resumed. It got broke because my new 'httpreq' field
  in the main curl struct. I should get slapped. I added a test case for
  this now, so I won't be able to ruin this again without noticing.

- Added a test case for content-length verifying when downloading HTTP.

- Made the progress meter title say if the transfer is being transfered. It
  makes the output slightly better for resumes.

- When dealing with Location: and HTTP return codes, libcurl will not attempt
  to follow the spirit of RFC2616 better. It means that when POSTing to a
  URL that is being following to a second place, the standard will judge on
  what to do. All HTTP codes except 303 and 305 will cause curl to make a
  second POST operation. 303 will make a GET and 305 is not yet supported.

  I also wrote two test cases for this POST/GET/Location stuff.

Version 7.6

Daniel (26 January 2001)
- Lots of mails back and forth with Bob Schader finally made me add a small
  piece of code in the HTTP engine so that HTTP upload resume works. You can
  now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
  the ending part of the file starting at given offet to the specified URL.

Version 7.6-pre4

Daniel (25 January 2001)
- I took hold of Rick Jones' question why we don't use recv() and send() for
  reading/writing to the sockets and I've now modified the sread() and
  swrite() macros to use them instead. If nothing else, they could be tested
  in the next beta-round coming right up.

- Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
  his research results in how to fix this. It turns out we have to invoke the
  function several times in some cases. The same goes for the SSL_write().

  I made some rather drastic changes all over libcurl to make all writes and
  reads get done on one single place so that this repeated-attempts thing
  would only have to be implemented at one point.

- Rick Jones spotted that the 'total time' counter really didn't measure the
  total time very accurate on subsecond levels.

- Johan Nilsson pointed out the need to more clearly specify that the timeout
  value you set for a download is for the *entire* download. There's currently
  no option available that sets a timeout for the connection phase only.

Daniel (24 January 2001)
- Ingo Ralf Blum submitted a series of patches required to get curl to compile
  properly with cygwin.

- Robert Weaver posted a fix for the win32 section of the curl_getenv() code
  that corrected a potential memory leak.

- Added comments in a few files in a sudden attempt to make the sources more
  easy to read and understand!

Daniel (23 January 2001)
- Added simple IPv6 detection in the configure script and made the version
  string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
  set if curl is compiled with IPv6 support enabled.

- Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
  IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...

- Made the URL globbing in the client possible to fail silently if there's an
  error in the globbing. It makes it almost intuitive, so when you don't
  follow the syntax rules, globbing is simply switched off and the raw string
  is used instead.

  I still think we'll get problems with IPv6-style IP-addresses when we *want*
  globbing on parts of the URL as the initial part of the URL will for sure
  seriously confuse the globber.

Daniel (22 January 2001)
- Björn Stenberg supplied a progress meter patch that makes it look better even
  during slow starts. Previously it made some silly assumptions...

- Added two FTP tests for -Q and -Q - stuff since it was being discussed on
  the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.

Daniel (19 January 2001)
- Made the Location: parsers deal with any-length URLs. Thus I removed the last
  code that restricts the length of URLs that curl supports.

- Added a --globoff test case (#28) and it quickly identified a memory problem
  in src/main.c that I took care of.

Version 7.6-pre3

Daniel (17 January 2001)
- Made the two former files lib/download.c and lib/highlevel.c become the new
  lib/transfer.c which makes more sense. I also did the rename from Transfer()
  to Curl_Transfer() in the other source files that use the transfer function
  in the spirit of using Curl_ prefix for library-scoped global symbols.

Daniel (11 January 2001)
- Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
  letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
  mention these letters to be escaped. This was posted as a feature request by
  Jorge Gutierrez and as a bug by Terry.

- Short options to curl that requires parameters can now be specified without
  having the option and its parameter space separated. -ofile works as good as
  -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
  options only, verbose --long-style options still must be separated with
  space from their parameters.

Daniel (8 January 2001)
- Francis Dagenais reported that the SCO compiler still fails when compiling
  curl due to that getpass_r() prototype. I've now put it around #ifndef
  HAVE_GETPASS_R in an attempt to please the SCO systems.

- Made some minor corrections to get the client to cleanup properly and I made
  the separator work again when getting multiple globbed URLs to stdout.

- Worked with Loic Dachary to get the make dist and make distcheck work
  correctly. The 'maketgz' script is now using the automake generated 'make
  dist' when creating release archives. Loic successfully made 'make rpms'
  automatically build RPMs!

Loic Dachary (6 January 2001)
- Automated generation of rpm packages, no need to be root.

- make distcheck generates a proper distribution (EXTRA_DIST
  in all Makefile.am modified to match FILES).

Daniel (5 January 2001)
- Huge client-side hack: now multiple URLs are supported. Any number of URLs
  can be specified on the command line, and they'll all be downloaded. There
  must be a corresponding -o or -O for each URL or the data will be written to
  stdout. This needs more testing, time to release a 7.6-pre package.

- The krb4 support was broken in the release. Fixed now.

- Huge internal symbol rename operation. All non-static but still lib-internal
  symbols should now be prefixed with 'Curl_' to prevent collisions with other
  libs. All public symbols should be prefixed with 'curl_' and the rest should
  be static and thus invisible to the outside world. I updated the INTERNALS
  document to say this as well.

Version 7.5.2

Daniel (4 January 2001)
- As Kevin P Roth suggested, I've added text to the man page for every command
  line option and what happens when you specify that option more than
  once. That hasn't been exactly crystal clear before.

- Made the configure script possible to run from outside the source-tree. For
  odd reasons I can't build curl properly outside though. It has to do with
  curl's dependencies on libcurl...

- Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
  The older piece is named CHANGES.0 and is added to the CVS repository in
  case anyone would need it.

- I added another file 'CVS-INFO' to the CVS. It contains information about
  files in the CVS that aren't included in release archives and how to build
  curl when you get the sources off CVS.

- Updated CONTRIBUTE and FAQ due to the new license.

Daniel (3 January 2001)
- Renamed README.libcurl to LIBCURL

- Changed headers in all sources files to the new dual license concept of
  curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
  accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
  release archive.
Daniel (30 December 2000)
- Made all FTP commands get sent with the trailing CRLF in one single write()
  as splitting them up seems to confuse at least some firewalls (FW-1 being
  one major).

Daniel (19 December 2000)
- Added file desrciptor and FILE handle leak detection to the memdebug system
  and thus I found and removed a file descriptor leakage in the ftp parts
  that happened when you did PORTed downloads.

- Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.

Daniel (12 December 2000)
- Multiple URL downloads with -O was still bugging. Not anymore I think or
  hope, or at least I've tried... :-O

- Francois Petitjean fixed another -O problem

Version 7.5.1

Daniel (11 December 2000)
- Cleaned up a few of the makefiles to use unix-style newlines only. As Kevin
  P Roth found out, at least one CVS client behaved wrongly when it found
  different newline conventions within the same file.

- Albert Chin-A-Young corrected the LDFLAGS use in the configure script for
  the SSL stuff.

Daniel (6 December 2000)
- Massimo Squillace correctly described how libcurl could use session ids when
  doing SSL connections.

- James Griffiths found out that curl would crash if the file you specify with
  -o is shorter than the URL! This took some hours to fully hunt down, but it
  is fixed now.

Daniel (5 December 2000)
- Jaepil Kim sent us makefiles that build curl using the free windows borland
  compiler. The root makefile now accepts 'make borland' to build curl with
  that compiler.

- Stefan Radman pointed out that the test makefiles didn't use the PERL
  variable that the configure scripts figure out. Actually, you still need
  perl in the path for the test suite to run ok.

- Rich Gray found numerous portability problems:
  * The SCO compiler got an error on the getpass_r() prototype in getpass.h
    since the curl one differed from the SCO one
  * The HPUX compiler got an error because of how curl did the sigaction
    stuff and used a define HPUX doesn't have (or need).
  * A few more problems remain to be researched.

- Paul Harrington experienced a core dump using https. Not much details yet.

Daniel (4 December 2000)
- Jörn Hartroth fixed a problem with multiple URLs and -o/-O.

Version 7.5

Daniel (1 December 2000)
- Craig Davison gave us his updates on the VC++ makefiles, so now curl should
  build fine with the Microsoft compiler on windows too.

- Fixed the libcurl versioning so that we don't ruin old programs when
  releasing new shared library interfaces.

Daniel (30 November 2000)
- Renamed docs/README.curl to docs/MANUAL to better reflect what the document
  actually contains.

Daniel (29 November 2000)
- I removed a bunch of '#if 0' sections from the code. They only make things
  harder to follow. After all, we do have all older versions in the CVS.

Version 7.5-pre5

Daniel (28 November 2000)
- I filled in more error codes in the man page error code list that had been
  lagging.

- James Griffiths mailed me a fine patch that introduces the CURLOPT_MAXREDIRS
  libcurl option. When used, it'll prevent location following more than the
  set number of times. It is useful to break out of endless redirect-loops.

Daniel (27 November 2000)
- Added two test cases for file://.

Daniel (22 November 2000)
- Added the libcurl CURLOPT_FILETIME setopt, when set it tries to get the
  modified time of the remote document. This is a special option since it
  involves an extra set of commands on FTP servers. (Using the MDTM command
  which is not in the RFC959)

  curl_easy_getinfo() got a corresponding CURLINFO_FILETIME to get the time
  after a transfer. It'll return a zero if CURLOPT_FILETIME wasn't used or if
  the time wasn't possible to get.

  --head/-I used on a FTP server will now present a 'Last-Modified:' header
  if curl could get the time of the specified file.

- Added the option '--cacert [file]' to curl, which allows a specified PEM
  file to be used to verify the peer's certificate when doing HTTPS
  connections. This has been requested, rather recently by Hulka Bohuslav but
  others have asked for it before as well.

Daniel (21 November 2000)
- Numerous fixes the test suite has brought into the daylight:

   * curl_unescape() could return a too long string
   * on ftp transfer failures, there could be memory leaks
   * ftp CWD could use bad directory names
   * memdebug now uses the mprintf() routines for better portability
   * free(NULL) removed when doing resumed transfers

- Added a bunch of test cases for FTP.

- General cleanups to make less warnings with gcc -Wall -pedantic.

- I made the tests/ftpserver.pl work with the most commonly used ftp
  operations. PORT, PASV, RETR, STOR, LIST, SIZE, USER, PASS all work now. Now
  all I have to do is integrate the ftp server doings in the runtests.pl
  script so that ftp tests can be run the same way http tests already run.

Daniel (20 November 2000)
- Made libcurl capable of dealing with any-length URLs. The former limit of
  4096 bytes was a bit annoying when people wanted to use curl to really make
  life tough on a web server. Now, the command line limit is the most annoying
  but that can be circumvented by using a config file.

  NOTE: there is still a 4096-byte limit on URLs extracted from Location:
  headers.

- Corrected the spelling of 'resolve' in two error messages.

- Alexander Kourakos posted a bug report and a patch that corrected it! It
  turned out that lynx and wget support lowercase environment variable names
  where curl only looked for the uppercase versions. Now curl will use the
  lowercase versions if they exist, but if they don't, it'll use the uppercase
  versions.

Daniel (17 November 2000)
- curl_formfree() was added. How come no one missed that one before? I ran the
  test suite with the malloc debug enabled and got lots of "nice" warnings on
  memory leaks. The most serious one was this. There were also leaks in the
  cookie handling, and a few errors when curl failed to connect and similar
  things. More tests cases were added to cover up and to verify that these
  problems have been removed.

- Mucho updated config file parser (I'm dead tired of all the bug reports and
  weird behaviour I get on the former one). It works slightly differently now,
  although I doubt many people will notice the differences. The main
  difference being that if you use options that require parameters, they must
  both be specified on the same line. With this new parser, you can also
  specify long options without '--' and you may separate options and
  parameters with : or =. It makes a config file line could look like:

        user-agent = "foobar and something"

  Parameters within quotes may contain spaces. Without quotes, they're
  expected to be a single non-space word.

  Had to patch the command line argument parser a little to make this work.

- Added --url as an option to allow the URL to be specified this way. It makes
  way nicer config files. The previous way of specifying URLs in the config
  file doesn't work anymore.

Daniel (15 November 2000)
- Using certain characters in usernames or passwords for HTTP authentication
  failed. This was due to the mprintf() that had a silly check for letters,
  and if they weren't isprint() they weren't outputed "as-is". This caused
  passwords and usernames using '§' (for example) to fail.

Version 7.4.2

Daniel (15 November 2000)
- 'tests/runtests.pl' now sorts the test cases properly when 'all' is used.

Daniel (14 November 2000)
- I fell over the draft-ietf-ftpext-mlst-12.txt Internet Draft titled
  "Extensions to FTP" that contains a defined way how the ftp command SIZE
  could be assumed to work.

- Laurent Papier posted a bug report about using "-C -" and FTP uploading a
  file that isn't prsent on the server. The server might then return a 550 and
  curl will fail. Should it instead as Laurent Papier suggests, start
  uploading from the beginning as a normal upload?

Daniel (13 November 2000)
- Fixed a crash with the followlocation counter.

- While writing test cases for the test suite, I discovered an old limitation
  that prevented -o and -T to be used at the same time. I removed this
  immediately as this has no relevance in the current libcurl.

- Chris Faherty fixed a free-twice problem in lib/file.c

- I fixed the perl http server problem in the test suite.

Version 7.4.2 pre4

Daniel (10 November 2000)
- I've (finally) started working on the curl test suite. It is in the new
  tests/ directory. It requires sh and perl. There's a TCP server in perl and
  most of the other stuff running a pretty simple shell script.

  I've only made four test cases so far, but it proves the system can work.

- Laurent Papier noticed that curl didn't set TYPE when doing --head checks
  for sizes on FTP servers. Some servers seem to return different sizes
  depending on whether ASCII or BINARY is used!

- Laurent Papier detected that if you appended a FTP upload and everything was
  already uploaded, curl would hang.

- Angus Mackay's getpass_r() in lib/getpass.c is now compliant with the
  getpass_r() function it seems some systems actually have.

- Venkataramana Mokkapati detected a bug in the cookie parser and corrected
  it.  If the cookie was set for the full host name (domain=full.host.com),
  the cookie was never sent back because of a faulty length comparison between
  the set domain length and the current host name.

Daniel (9 November 2000)
- Added a configure check for gethostbyname in -lsocket (OS/2 seems to need
  it). Added a check for RSAglue/rsaref for the cases where libcrypto is found
  but libssl isn't. I haven't verified this fix yet though, as I have no
  system that requires those libs to build.

Version 7.4.2 pre3

Daniel (7 November 2000)
- Removed perror() outputs from getpass.c. Angus Mackay also agreed to a
  slightly modified license of the getpass.c file as the prototype was changed.

Daniel (6 November 2000)
- Added possibility to set a password callback to use instead of the built-in.
  They're controled with curl_easy_setopt() of course, the tags are
  CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA.

- Used T. Bharath's thinking and fixed the timers that showed terribly wrong
  times when location: headers were followed.

- Emmanuel Tychon discovered that curl didn't really like user names only in
  the URL. I corrected this and I also fixed the since long living problem
  with URL encoded user names and passwords in the URLs. They should work now.

Daniel (2 November 2000)
- When I added --interface, the new error code that was added with it was
  inserted in the wrong place and thus all error codes from 35 and upwards got
  increased one step. This is now corrected, we're back at the previous
  numbers. All new exit codes should be added at the end.

Daniel (1 November 2000)
- Added a check for signal() in the configure script so that if sigaction()
  isn't present, we can use signal() instead.

- I'm having a license discussion going on privately. The issue is yet again
  GPL-licensed programs that have problems with MPL. I am leaning towards
  making a kind of dual-license that will solve this once and for all...

Daniel (31 October 2000)
- Added the packages/ directory. I intend to let this contain some docs and
  templates on how to generate custom-format packages for various platforms.
  I've now removed the RPM related curl.spec files from the archive root.

Daniel (30 October 2000)
- T. Bharath brought a set of patches that bring new functionality to
  curl_easy_getinfo() and curl_easy_setopt(). Now you can request peer
  certificate verification with the *setopt() CURLOPT_SSL_VERIFYPEER option
  and then use the CURLOPT_CAINFO to set the certificate to verify the remote
  peer against. After an such an operation with a verification request, the
  *_getinfo() option CURLINFO_SSL_VERIFYRESULT will return information about
  whether the verification succeeded or not.

Daniel (27 October 2000)
- Georg Horn brought us a splendid patch that solves the long-standing
  annoying problem with timeouts that made curl exit with silly exit codes
  (which as been commented out lately). This solution is sigaction() based and
  of course then only works for unixes (and only those unixes that actually
  have the sigaction() function).

Daniel (26 October 2000)
- Björn Stenberg supplied a patch that fixed the flaw mentioned by Kevin Roth
  that made the password get echoed when prompted for interactively. The
  getpass() function (now known as my_getpass()) was also fixed to not use any
  static buffers. This also means we cannot use the "standard" getpass()
  function even for those systems that have it, since it isn't thread-safe.

- Kevin Roth found out that if you'd write a config file with '-v url', the
  url would not be used as "default URL" as documented, although if you wrote
  it 'url -v' it worked! This has been corrected now.

- Kevin Roth's idea of using multiple -d options on the same command line was
  just brilliant, and I couldn't really think of any reason why we shouldn't
  support it! The append function always append '&' and then the new -d
  chunk. This enables constructs like the following:

        curl -d name=daniel -d age=unknown foobarsite.com

Daniel (24 October 2000)
- I fixed the lib/memdebug.c source so that it compiles on Linux and other
  systems. It will be useful one day when someone else but me wants to run the
  memory debugging system.

Daniel (23 October 2000)
- I modified the maketgz and configure scripts, so that the configure script
  will fetch the version number from the include/curl/curl.h header files, and
  then the maketgz doesn't have to rebuild the configure script when I build
  release-archives.

- Björn Stenberg and Linus Nielsen correctly pointed out that curl was silly
  enough to not allow @-letters in passwords when they were specified with the
  -u or -U flags (CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD). This also
  suggests that curl probably should url-decode the password piece of an URL
  so that you could pass an encoded @-letter there...

Daniel (20 October 2000)
- Yet another http server barfed on curl's request that include the port
  number in the Host: header always. I now only include the port number if it
  isn't the default (80 for HTTP, 443 for HTTPS). www.perl.com turned out to
  run one of those nasty servers.

- The PHP4 module for curl had problems with referer that seems to have been
  corrected just yesterday. (Sterling Hughes of the PHP team confirmed this)

Daniel (17 October 2000)
- Vladimir Oblomov reported that the -Y and -y options didn't work. They
  didn't work for me either. This once again proves we should have that test
  suite...

- I finally changed the error message libcurl returns if you try a https://
  URL when the library wasn't build with SSL enabled. It will now return this
  error:
        "libcurl was built with SSL disabled, https: not supported!"

  I really hope it will make it a bit clearer to users where the actual
  problem lies.

Version 7.4.1

Daniel (16 October 2000)
- I forgot to remove some of the malloc debug defines from the makefiles in
  the release archive (of course).

Version 7.4

Daniel (16 October 2000)
- The buffer overflow mentioned below was posted to bugtraq on Friday 13th.

Daniel (12 October 2000)
- Colin Robert Phipps elegantly corrected a buffer overflow. It could be used
  by an evil ftp server to crash curl. I took the opportunity of replacing a
  few other sprintf()s into snprintf()s as well.

Daniel (11 October 2000)
- Found some more memory leaks. This new simple memory debugger has turned out
  really useful!

Version 7.4 pre6

Daniel (9 October 2000)
- Florian Koenig pointed out that the bool typedef in the curl/curl.h include
  file was breaking PHP 4.0.3 compiling. The bool typedef is not used in the
  public interface and was wrongly inserted in that header file.

- Jörg Hartroth corrected a minor memory leak in the src/urlglob.c stuff. It
  didn't harm anyone since the memory is free()ed on exit anyway.

- Corrected the src/main.c. We use the _MPRINTF_REPLACE #define to use our
  libcurl-printf() functions. This gives us snprintf() et al on all
  platforms. I converted the allocated useragent string to one that uses a
  local buffer.

- I've set an #if 0 section around the Content-Transfer-Encoding header
  generated in lib/formdata.c. This will hopefully make curl do more
  PHP-friendly multi-part posts.

Version 7.4 pre5

Daniel (9 October 2000)
- Nico Baggus found out that curl's ability to force a ASCII download when
  using FTP was no longer working! I corrected this. This problem was probably
  introduced when I redesigned libcurl for version 7.

- Georg Horn provided a source example that proved a memory leak in libcurl.
  I added simple memory debugging facilities and now we can make libcurl log
  all memory fiddling functions. An additional perl script is used to analyze
  the output logfile and to match malloc()s with free()s etc. The memory leak
  Georg found turned out to be the main cookie struct that cookie_cleanup()
  didn't free! The perl script is named memanalyze.pl and it is available in
  the CVS respository, not in the release archive.

Daniel (8 October 2000)
- Georg Horn found a GetHost() problem. It turned out it never assigned the
  pointer in the third argument properly! This could make a crash, or at best
  a memory leak!

Version 7.4 pre4

Daniel (6 October 2000)
- Is the -F post following the RFC 1867 spec? We had this dicussion on the
  mailing list since it appears curl can't post -F form posts to a PHP
  receiver... I've been in touch with the PHP developers about this.

- Domenico Andreoli found out that the long option '--proxy' wasn't working
  anymore! The option parser got confused when I added the --proxytunnel for
  7.3. This was indeed a very old flaw that hasn't turned up until now...

- Jörn Hartroth provided patches, updated makefiles and two new files for DLL
  stuff on win32. He also pointed out that lib source files were compiled with
  -I../src which isn't only wrong but plain stupid!

- Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
  a local variable badly, that could lead to crashes.

Version 7.4 pre3

Daniel (4 October 2000)
- More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
  as is the -w section in curl.1. I added two options to enable the user to
  get information about the received headers' size and the size of the HTTP
  request. T. Bharath requested them.

Daniel (3 October 2000)
- Corrected a sever free() before use in the new add_buffer_send()! ;-)

Version 7.4 pre2

Daniel (3 October 2000)
- Jason S. Priebe sent me patches that changed the way curl issues HTTP
  requests. The entire request is now issued in one single shot. It didn't do
  this previously, and it has turned out that since the common browsers do it
  this way, some sites have turned out to work with browsers but not with
  curl! Although this is not a client-side problem, we want to be able to
  fully emulate browsers, and thus we have now adjusted the networking layer
  to slightly more appear as a browser. I adjusted Jason's patch, the faults
  are probably mine.

Daniel (2 October 2000)
- Anyone who ever uploaded data with curl on a slow link has noticed that the
  progess meter is updated very infrequently. That is due to the large buffer
  size curl is using. It reads 50Kb and sends it, updates the progress meter
  and loops. 50Kb is very much on a slow link, although it is pretty neat to
  use on a fast one.

  I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
  start with. If curl's average upload speed is faster than buffer size bytes
  per second, curl will increase the used buffer size up to max 50Kb. It
  should make the progress meter work better.

Version 7.4 pre1

Daniel (29 September 2000)
- Ripped out the -w stuff from the library and put in the curl tool. It gets
  all the relevant info from the library using the new curl_easy_getinfo()
  function.

- brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
  removed a compiler warning from hostip.c that OpenBSD people get.

Daniel (28 September 2000)
- Of course (I should probably get punished somehow) I didn't properly correct
  the #include lines for the base64 stuff in the kerberos sources in the just
  released 7.3 package. They still include the *_krb.h files! Now, the error
  is sooo very easy to spot and fix so I won't bother with a quick bug fix
  release. I'll post a patch whenever one is needed instead. It'll be
  available in the CVS in a few minutes anyway.

Version 7.3

Daniel (28 September 2000)
- Removed the base64_krb.[ch] files. They've now replaced the former
  base64.[ch] files.

Daniel (26 September 2000)
- Updated some docs.

- I changed the OpenSSL fix to work with older versions as well. The posted
  patch was only working with 0.9.6 and no older ones.

Version 7.3-pre8

Daniel (25 September 2000)
- Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
  showed us what needed to get patched in order to make it build properly
  again.

- Dirk Kruschewski found a bug in the cookie parser. I made an alternative
  approach to the solution Dirk himself suggested. The bug made a cookie
  header that didn't end with a trailing semicolon to not get parsed.

- I've marked -c and -t deprecated now. If you use any of them, curl will tell
  you to use "-C -" or "-T -" instead. I don't think occupying two letters for
  nearly identical functions is good use. Also, -T - kind of follows the curl
  tradition of using - for stdin where a file name is expected.

Daniel (23 September 2000)
- Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
  work!

Daniel (21 September 2000)
- The kerberos code is not quite thread-safe yet. There are a few more globals
  that need to be take care of. Let's get the upload working first!

Daniel (20 September 2000)
- Richard Prescott solved another name lookup buffer size problem. I took this
  opportunity to rewrite the GetHost() function. With these large buffer
  sizes, I think keeping them as local arrays quickly turn ugly. I now use
  malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
  large buffer in case of demand (errno == ERANGE) in case a solution like
  that would become necessary. I still want to avoid that kind of nastiness.

- Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
  as smooth as it could.

- Added a docs/examples directory with two tiny example sources that show how
  to use libcurl. I hope users will supply me with more useful examples
  further on.

- Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
  config struct in the src/main.c file since certain compilers have that word
  "reservered".  I figure that is some kind of C++ decease.

- Updated the curl.1 man page with --interface and --krb4.

- Modified the base64Encode() function to work like the kerberos one, so that
  I could remove the use of that. There is no need for *two* base64 encoding
  functions! ;-)

Version 7.3pre5

Daniel (19 September 2000)
- The kerberos4-layer source code that is much "influenced" by the original
  krb4 source code, through yafc into curl, was using quite a lot of global
  variables. libcurl can't work properly with globals like that why I had to
  clean up almost every function in the new security.c to make them use
  connection specific variables instead of the globals. I just hope I didn't
  destroy anything now... :-) configure updated, version string now reflects
  krb4 built-in. It almost works now. Only uploads are still being naughty.

Version 7.3pre3

Daniel (18 September 2000)
- Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
  curl. Martin is the primary author of the ftp client named yafc and he did
  not hesitate to help us implement this when I asked him. Many and sincere
  thanks to a splendid effort. It didn't even take many hours!

- Stephen Kick supplied a big patch that introduces the --interface flag to
  the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
  outgoing interface to use for your request. This may not work on all
  platforms. This needs testing.

- Richard Prescott noticed that curl on Tru64 unix could core dumped if the
  name didn't resolve properly. This was due to the GetHost() function not
  returning an error even though it failed on some platforms!

Daniel (15 September 2000)
- Updated all sorts of documents in regards to the new proxytunnel support.

Version 7.3pre2

Daniel (15 September 2000)
- Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
  Adjusted it. Added better info message when setting up the tunnel and the
  pasv message when doing the second connect.

Version 7.3pre1

Daniel (15 September 2000)
- libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
  second connection on ftp needed that.

- TheArtOfHTTPScripting was corrected all over. I both type and spell really
  bad at times!

Daniel (14 September 2000)
- -p/--proxytunnel was added to 'curl'. It uses the new
  CURLOPT_HTTPPROXYTUNNEL libcurl option that allows "any" protocol to tunnel
  through the specified http proxy. At the moment, this should work with ftp.

Daniel (13 September 2000)
- Jochen Schaeuble found that file:// didn't work as expected. Corrected this
  and mailed the patch to the mailing list.

Daniel (7 September 2000)
- I changed the #define T() in curl.h since it turned out it wasn't really
  a good symbol to use (when you compiled PHP with curl as a module, that
  define collided with some IMAP define or something). This was posted to the
  PHP bug tracker.

- I added extern "C" stuff in two header files to better allow libcurl usage
  in C++ sorces. Discussions on the libcurl list with Danny Horswell lead to
  this.

Version 7.2.1

Daniel (31 August 2000)
- Albert Chin-A-Young fixed the configure script *again* and now it seems to
  detect Linux name resolving properly! (heard that before?)

- Troels Walsted Hansen pointed out that downloading a file containing the
  letter '+' from an ftp server didn't work. It did work from HTTP though and
  the reason was my lame URL decoder.

- I happened to notice that -I didn't at all work on ftp anymore. I corrected
  that.

Version 7.2

Daniel (30 August 2000)
- Understanding AIX is a hard task. I believe I'll never figure out why they
  solve things so differently from the other unixes. Now, I'm left with the
  AIX 4.3 run-time warnings about duplicate symbols that according to this
  article (http://www.geocrawler.com/archives/3/405/1999/9/0/2593428/) is a
  libtool flaw. I tried the mentioned patch, although that stops the linking
  completely.

  So, if I select to ignore the ld warnings there are compiler warnings that
  fill the screen pretty bad when curl compiles. It turns out that if I want
  to '#include <arpa/inet.h>', I can get tid of the warnings by include the
  following three include files before that one:

        #include <net/if_dl.h>
        #include <sys/mbuf.h>
        #include <netinet/if_ether.h>

  Now, is it really sane to add those include files before arpa/inet.h in all
  the source files that include it?

  Thanks to Albert Chin-A-Young at thewrittenword.com who gave me the AIX
  login to try everything on.

Daniel (24 August 2000)
- Jan Schmidt supplied us a new VC6 makefile for Windows as the previous one
  was not up to date but lacked several object files.

- More work on the naming.

- Albert Chin-A-Young provided a configure-check for large file support, as
  some systems seem to need that for them to work. Had to change the position
  for the config.h include file in every .c file in the libcurl dir...

- As suggested on the mailing list (by Troy Engel), I did use a --data-binary
  option instead of the messy way I've left described below. It seems to
  work. The libcurl fix remained the same as yesterday.

Daniel (23 August 2000)
- Back on the -d stripping newlines thing. The 'plain post' thing was added
  when I had no thought of that one could actually post binary data with
  it. Now, I have to add this functionality in a graceful manner and I think
  I've managed to come up with a way: '-d @file;binary' will thus post the
  file binary, exactly as its contents are. It is implemented with a new
  *setopt() option (CURLOPT_POSTFIELDSIZE) to set the postfield size, since
  libcurl can't strlen() the data in these cases.

- Albert Chin-A-Young made some very serious efforts and all the name
  resolving problems seem to have been sorted out now on all the platforms
  that previously showed them. I'll make another release now anyday because of
  this.

- The FAQ was much enhanced when it comes to the licensing issues thanks to
  Bjorn Reese.

Daniel (21 August 2000)
- Rick Welykochy pointed out a problem when you use -d to post and you want to
  keep the newlines, as curl strips them off as a bonus before posting...
  This needs to be addressed.

Version 7.1.1

Daniel (21 August 2000)
- Got more people involved in the gethostbyname_r() mess. Caolan McNamara sent
  me configure-code that turned out to be very similar to my existing tests
  which only make me more sure I'm on the right path. I changed the order of
  the tests slightly, as it seems that some compilers don't yell error if a
  function is used with too many parameters. Thus, the first tested function
  will seem ok... Let's hope more compilers think of too-few parameters as bad
  manners, as we're now trying the functions in that order; fewer first. I
  should also add that Lars Hecking mailed me and volunteered to run tests on
  a few odd systems. Coalan is keeping his work over at
  http://www.csn.ul.ie/~caolan/publink/gethostbyname_r/. Might be handy in the
  future as well.

Daniel (18 August 2000)
- I noticed I hadn't increased the name lookup buffer in lib/ftp.c. I don't
  think this is the reason for the continued trouble though.

Daniel (17 August 2000)
- Fred Noz corrected my stupid mistakes in the gethostbyname_r() fluff. It
  should affect some AIX, Digital Unix and HPUX 10 systems.

Daniel (15 August 2000)
- Mathieu Legare compiled and build 7.1 without errors on both AIX 4.2 as well
  as AIX 4.3. Now why did problems occur before?

- Fred Noz reported a -w/--write-out bug that caused it to malfunction when
  used combined with multiple URL retrievales. All but the first display got
  screwed up!

Daniel (11 August 2000)
- Jason Priebe and an anonymous friend found some host names the Linux version
  of curl could not resolve. It turned out the buffer used to retrieve that
  information was too small. Fixed. One could argue about the usefulness of
  not having the slightest trace of a man page for gethostbyname_r() on my
  Linux Redhat installation...

Daniel (10 August 2000)
- Balaji S Rao was first in line to note the missing possibility to replace
  the Content-Type: and Content-Length: headers when doing -d posts. I added
  the possibility just now. It seems some people wants to do standard posts
  using custom Content-Types.

Daniel (8 August 2000)
- Mike Dowell correctly discovered that curl did not approve of URLs with no
  user name but password. As in 'http://:foo@haxx.se'. I corrected this.

Version 7.1

Daniel (7 August 2000)
- My AIX 4 fix does not work. I need help from a AIX 4 hacker.

- I added my new document in the docs directory. It is aimed to become a sort
  of tutorial on how to do HTTP scripting with curl.

Daniel (4 August 2000)
- Working with Rich Gray on compiling curl for lots of different platforms.
  My fix for AIX 3.2 was not good enough and was slightly changed, I had to
  move an include file before another, as is now described in the source.

  AIX 4.2 (4.X?) has different gethostbyname_r() and gethostbyaddr_r()
  functions that the configure script didn't check for and thus the compile
  broke with an error. I have now changed the gethostbyname_r() check in the
  configure file to support all three versions of both these functions. My
  implementation that uses the AIX-style is though not yet verified and I may
  get problems to fix it if it turns out to bug since I don't have access to
  any system using that.

  For problems like that, I made the configure script allow --disable-thread
  to completely switch off the check for threadsafe versions of a few
  functions and thus go with the "good old versions" that tend to work
  although will break thread-safeness for libcurl. Most people won't use
  libcurl for other things than curl though, and curl doesn't need a
  thread-safe lib.

- Working on my big tutorial about HTTP scripting with curl.

Daniel (1 August 2000)
- Rich Gray spotted a problem in src/setup.h caused by a #define strequal()
  that was just a left-over from passed times. The strequal() is now a true
  function supplied by libcurl for a portable case insensitive string
  comparison. I added the prototypes in include/curl.h and removed the
  now obsolete #define.

- Igor Khristophorov made a fix to allow resumed download from Sun's
  JavaWebServer/1.1.1. It seems that their server sends bad Content-Range
  headers.

- The makefiles forced a static library build, which is bad since we now use
  libtool and thus have excellent shared library support! Albert Chin-A-Young
  found out.

Version 7.0.11beta

Daniel (1 August 2000)
- Albert Chin-A-Young pointed out that 'make install' did not properly create
  the header include directory, why it failed to install the header files as
  it should. Automake isn't really equipped to deal with subdirectories
  without Makefiles in any nice way. I had to run ahead and add Makefiles in
  both include and include/curl before I managed to create a top-level
  makefile that succeeds in install everything properly!

- Ok, no more "features" added now. Let's just verify that there's no major
  flaws added now.

Daniel (31 July 2000)
- Both Jeff Schasny and Ketil Froyn asked me how to tell curl not to send one
  of those internally generated headers. They didn't settle with the blank
  ones you could tell curl to use. I rewrote the header-replace stuff a
  little. Now, if you replace an internal header with your own and that new
  one is a blank header you will only remove the internal one and not get any
  blank. I couldn't figure out any case when you want that blank header.

Daniel (29 July 2000)
- It struck me that the lib used localtime() which is not thread-safe, so now
  I use localtime_r() in the systems that has it.

- I went through this entire document and removed all email addresses and left
  names only. I've really made an effort to always note who brought be bug
  reports or fixes, but more and more people ask me to remove the email
  addresses since they become victims for spams this way. Gordon Beaton got me
  working on this.

Daniel (27 July 2000)
- Jörn Hartroth found out that when you specified a HTTP proxy in an
  environment variable and used -L, curl failed in the second fetch. I
  corrected this problem and posted a patch to the list. No need for an extra
  beta release just for this.

Version 7.0.10beta

Daniel (27 July 2000)
- So, libtool replaced two of my files with symbolic links and I forgot to add
  the two new libtool files to the release archive (and they were added as
  symlinks as well!) This of course lead to that the configure script failed
  on 7.0.9...

Version 7.0.9beta

Daniel (25 July 2000)
- Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl
  libtoolified, just as we've wanted for a while now. He also made the
  recently added man pages get installed properly on 'make install' and some
  other nice cleanups.

- In a discussion with Eetu Ojanen it struck me that if we use curl to get a
  page using a password, and that page then sends a Location: to another
  server that curl follows, curl will send the user name and password to that
  server as well.

  Now, I'll never be able to make curl do Location: following all that perfect
  and you're all sooner or later required to write a script to do several
  fetches when you're doing advanced stuff, but now I've modified curl to at
  least *only* send the user name and password to the original server. Which
  means that if get a page from server A with a password, that forwards curl
  to server B, curl won't use the password there. If server B then forwards
  curl back to server A again, the password will be used again.

  This is not a perfect implementation, as in a browser case it would only use
  the password if the left-prefix of the first path is the same. I just think
  that this fix prevents a somewhat lurky "security hole".

  As a side-note in this subject: HTTP passwords are sent in cleartext and
  will never be considered to be safe or secure. Use HTTPS for that.

- As discussed on the mailing list, I converted the FTP response reading
  function into using select() which then allows timeouts (even under win32!)
  if the command-reply session gets too slow or dies completely. I made a
  default timeout on 3600 seconds unless anything else is specified, since I
  don't think anyone wants to wait more than that for a single character to
  get received...

- Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
  the rfc1867 form posts. He introduced 'name=<file' which brings a means to
  suuply very large text chunks read from the given file name. It differs from
  'name=@file' in the way that this latter thing is marked in the uploaded
  contents as a file upload, while the first is just text (as in a input or
  textarea field). Torsten also corrected a bug that would happen if you used
  %s or similar in a -F file name.

- As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
  files to/from FTP using type ASCII curl should not expect the transfer to be
  the exact size reported by the server as the file size. Since ASCII may very
  well mean that the content is translated while transfered, the final size
  may very well differ. Therefor, curl now ignores the file size when doing
  ASCII transfers in FTP.

Daniel (24 July 2000)
- Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
  port number to be set separately from the proxy host name.

- Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.

- The FTP transfer code now accepts a 250-code as well as the previously
  accepted 226, after a successful file transfer. Mohan <mnair at
  evergreen-funds.com> pointed this out.

- The check for *both* nsl and socket was never added in the v7 configure.in
  when I moved the main branch. I re-added that check to configure.in. This was
  discovered by Rich Gray.

- Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
  curl_disconnect() which of course meant libcurl ate memory.

- Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
  properly include the port number if non-default ports were used. This should
  now have been fixed.

- HTTP connect errors now return errors earlier. This was most notably causing
  problems when the HTTPS certificate had problems and later caused a crash.
  Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
  and suggesting a fix...

Daniel (21 June 2000)
- After a "bug report" I received where the user was using both -F and -I in a
  HTTP request (it severly confused the library I should add), I added some
  checks to src/main.c that prevents setting more than one HTTP request
  command, no matter what the user wants! ;-)

Version 7.0.8beta

Daniel (20 June 2000)
- I did a major replace in many files to use the new curl domain haxx.se
  instead of the previous one.

- As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
  makes a POST after it has followed a location. When the initial POST has
  been done, it'll turned into a GET for the further requests. This is only
  interesting when using -L/--location *and* doing a POST at the same time.

  While messing with this, I added another weird feature I call 'auto
  referer'. If you append ';auto' to the right of a given referer string (or
  only use that string as referer), libcurl will automatically set the
  previoud URL as refered when it follows a Location: and gets a succeeding
  document.

- My hero Rich Gray found the very obscure FTP bug that happened to him only
  when passing through a particular firewall and using the PORT command. It
  turned out that PORT was the only command in the lib/ftp.c source that
  didn't send a proper \r\n sequence but instead used the faulty \n which as
  it seemed is supported by most major ftp servers... :-O

Version 7.0.7beta

Daniel (16 June 2000)
- I had avoided this long enough now, so I moved the alternative progress bar
  stuff from the lib and added it to the client code. This is now using the
  recently added progress callback and it seems to work pretty much like
  before. Since it is only one progress bar and you and download and upload at
  the same time, this bar shows the combined progress of both directions. This
  code was just ported from the old place to this, Lars is still our saviour!
  ;-) This also made the documentation more accurate since I never removed
  this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
  from the library since the lib has only one internal progress meter and it
  will never get another. It is although likely that the internal one also
  will be moved to the client code in the future (when I have other means of
  getting the writeout data and move that too to the client).

- I took the opportunity to verify that standard progress meter works and I
  found out it didn't get inited properly. Grrr. I corrected that as well.

Daniel (15 June 2000)
- I thought I'd better verify that the -F option still works in v7 and of
  course it didn't... :-/ Anyway, I had the problems I could discover
  corrected. About one month of beta testing and not a single person has used
  this feature with v7?

- Björn correctly pointed out that the --progress-bar still doesn't work in
  v7. Hm.

Daniel (14 June 2000)
- Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
  should. I corrected this.

Version 7.0.6beta

Daniel (14 June 2000)
- Björn Stenberg pointed out several problems (related to win32 compiling):
  lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
  src/main.c had several minor problems
  lib/makefile.m32 had getpass.[co] twice
  src/config-win32.h lacked the HAVE_FCNTL_H define
  both config-win32.h files now only set the HAVE_UNISTD_H define if the
  define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
  to set it.

Version 7.0.5beta

Daniel (14 June 2000)
- Applied Luong Dinh Dung's comments about a few win32 compile problems.

- Applied Björn Stenberg's suggested fix that turns the win32 stdout to
  binary. It won't do it if the -B / --use-ascii option is used. That option
  is now an extended version of the previous -B /--ftp--ascii. The flag was
  already in use be the ldap as well so the new name fits pretty good. The
  libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
  obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
  compiler around.

Daniel (13 June 2000)
- Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
  since it free()ed the main curl struct *twice*. This is now corrected.

Daniel (9 June 2000)
- Updated the RESOURCES file, added a README.win32 file.

Daniel (8 June 2000)
- So I finally added the progress callback to the *setopt() options and it
  should work now. I don't have the energy to write any test program for it
  right now.
- Made the callback function typedefs public in curl/curl.h for comfort. Just
  in case anyone wanna fiddle with such pointers.
- Updated the curl_easy_setopt() man page accordingly.

Version 7.0.4beta

Daniel (2 June 2000)
- I noticed that when doing Location: following, we lost custom headers in all
  but the first request.
- Removed the 'HttpPost' struct and moved the header stuff to the more generic
  curl_slist.
- Added some better slist-cleanups in src/main.c

Version 7.0.3beta

Daniel (31 May 2000)
- So I discovered that I released the 7.0.2beta without it being able to
  compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
  feature a different amount of arguments on different systems so I had to add
  a configure check for this and adjust the code slightly.

Version 7.0.2beta

Daniel (29 May 2000)
- Corrected the bits.* assignments when using CURLOPT options that only
  toggles one of those bits.

- Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
  usage of the gethostbyname_r() and similar functions in case they're around,
  since that make libcurl much better threadsafe in many systems (such as
  solaris). I added the checks for these functions to the configure script.

  I can't explain why, but the inet_ntoa_r() function did not appear in my
  Solaris include files, I had to add my own include file for this for now.

Daniel (22 May 2000)
- Jörn Hartroth brought me fixes to make the win32 version compile properly as
  well as a rename of the 'interface' field in the urldata struct, as it seems
  to be reserved in some gcc versions!

- Rich Gray struck back with yet some portability reports. Data General DG/UX
  needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
  More fixes are expected as a result of Richies very helpful work.

Version 7.0.1beta

Daniel (21 May 2000)
- Updated lots of #defines, enums and variable type names in the library. No
  more weird URG or URLTAG prefixes. All types and names should be curl-
  prefixed to avoid name space clashes. The FLAGS-parameter to the former
  curl_urlget() has been converted into a bunch of flags to use in separate
  setopt calls. I'm still focusing on the easy-interface, as the curl tool is
  now using that.

- Bjorn Reese has provided me with an asynchronous name resolver that I plan
  to use in upcoming versions of curl to be able to gracefully timeout name
  lookups.

Version 7.0beta

Daniel (18 May 2000)
- Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
  source codes to be dependent on the lib version. This define is now set to
  a dexadecimal number, with 8 bits each for major number, minor number and
  patch number. In other words, version 1.2.3 would make it 0x010203. It also
  makes a larger number a newer version.

Daniel (17 May 2000)
- Martin Kammerhofer correctly pointed out several flaws in the FTP range
  option. I corrected them.
- Removed the win32 winsock init crap from the lib to the src/main.c file
  in the application instead. They can't be in the lib, especially not for
  multithreaded purposes.

Daniel (16 May 2000)
- Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
  There is still more work to do, but the first step is now taken.
  <curl/easy.h> is the include file to use.

Daniel (14 May 2000)
- FTP URLs are now treated slightly different, more according to RFC 1738.
- FTP sessions are now performed differently, with CWD commands to change
  directory instead of RETR/STOR/LIST with the full path. Discussions with
  Rich Gray made me notice these problems.
- Janne Johansson discovered and corrected a buffer overflow in the
  src/usrglob.c file.
- I had to add a lib/strequal.c file for doing case insensitive string
  compares on all platforms.

Daniel (8 May 2000):
- Been working lots on the new lib.
- Together with Rich Gray, I've tried to adjust the configure script to work
  better on the NCR MP-RAS Unix.

Daniel (2 May 2000):
- Albert Chin-A-Young pointed out that I had a few too many instructions in
  configure.in that didn't do any good.

Daniel (24 April 2000):
- Added a new paragraph to the FAQ about what to do when configure can't
  find OpenSSL even though it is installed. Supplied by Bob Allison

Daniel (12 April 2000):
- Started messing around big-time to convert the old library interface to a
  better one...

Daniel (8 April 2000):
- Made the progress bar look better for file sizes between 9999 kilobytes
  and 100 megabytes. They're now displayed XX.XM.
- I also noticed that ftp fetches through HTTP proxies didn't add the user
  agent string. It does now.
- Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
  on a Linux machine. It still a) requires me to be root to do it, b) leaves
  the rpm packages laying at some odd place on my disk c) doesn't work to
  build the ssl version of curl since I didn't install openssl from an rpm
  package so now the rpm crap thinks I don't have openssl and refuses to build
  a package that depends on ssl... Did I mention I don't get along with RPM?
- Once again I received a bug report about autoconf not setting -L prior to -l
  on the command line when checking for libs. In this case it made the native
  cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
  reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
  is a pity there's no newer release around...

Daniel (4 April 2000):
- Marco G. Salvagno supplied me with two fixes that
  appearantly makes the OS/2 port work better with multiple URLs.

Daniel (2 April 2000):
- Another Location: fix. This time, when curl connected to a port and then
  followed a location with an absolute URL to another port, it misbehaved.

Daniel (27 March 2000):
- H. Daphne Luong pointed out that curl was wrongly
  messing up the proxy string when fetching a document through a http proxy,
  which screwed up multiple fetches such as in location: followings.

Daniel (23 March 2000):
- Marco G. Salvagno corrected my badly applied patch he
  actually already told me about!

- H. Daphne Luong brought me a fix that now makes curl
  ignore select() errors in the download if errno is EINTR, which turns out to
  happen every now and then when using libcurl multi-threaded...

Daniel (22 March 2000):
- Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
  was accidentally #defined in config-win32.h, which it shouldn't have been.
  The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
  makefile for MS VC++.

Daniel (21 March 2000):
- I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
  one of the AM_* macros searches for a BSD compatible install already. Janne
  Johansson made me aware of this.

Version 6.5.2

Daniel (21 March 2000):
- Paul Harrington quickly pointed out to me that 6.5.1
  crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
  the -D adjustments in src/main.c.

Version 6.5.1

Daniel (20 March 2000):
- An anonymous post on sourceforge correctly pointed out a possible buffer
  overflow in the curl_unescape() function for URL conversions. The main
  problem with this bug is that the ftp download uses that function and this
  single- byte overflow could lead to very odd bugs (as one reported by Janne
  Johansson).

Daniel (19 March 2000):
- Marco G. Salvagno supplied me with a series of patches
  that now allows curl to get compiled on OS/2. It even includes a section in
  the INSTALL file. Very nice job!

Daniel (17 March 2000):
- Wham Bang supplied a patch for the lib/Makefile.vc6
  file. We still need some fixes for the config-win32.h since it appears that
  VC++ and mingw32 have different opinions about (at least) unistd.h's
  existence.

Daniel (15 March 2000):
- I modified the -D/--dump-header workings so that it doesn't write anything
  to the file until it needs to. This way, you can actually use -b and -D
  on the same file if you want repeated invokes to store and read the cookies
  in that one single file.

- Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
  Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
  stuff from the sources (they're covered by the config-win32.h now).

- Pascal Gaudette fixed a missing ldap.c problem in the
  Makefile.vc6 file. He also addressed a problem in src/config-win32.h.

Daniel (14 March 2000):
- Paul Harrington pointed out that the 'http_code' variable in the -w output
  was never written. I fixed it now.

- Janne Johansson reported the complaints that OpenBSD does
  when getdate.c #includes malloc.h. It claims stdlib.h should be included
  instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
  the configure.in for malloc.h and stdlib.h.

Version 6.5

Daniel (13 March 2000):
- <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
  single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
  the standards say, but I added a white space between the name/value pairs to
  perhaps make them work better.

- Added the perl check back in the configure.in again since the mkhelp.pl
  script needs it!

- Made some beautifications in the curl man page.

Daniel (3 March 2000):
- Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
  HAVE_STRDUP.

Daniel (3 March 2000):
- Uploaded the 6.5pre2 package.

Daniel (2 March 2000):
- Removed the perl-programs from the distribution, they never made many people
  happy and I'll still keep them available on the web.

- Added the -w and -N stuff to the man page. Documented the new progress meter
  display in README.curl.

- Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
  Möller from the openssl development team helped bringing me the details for
  fixing an OpenSSL usage flaw. It became apparent when they released openssl
  0.9.5 since that barfed on curl's bad behavior (not seeding a random number
  thing).

- Yet another option: -N/--no-buffer disables buffering in the output stream.
  Probably most useful for very slow transfers when you really want to get
  every byte curl receives within some preferred time. Andrew <tmr at gci.net>
  suggested this.

- Damien Adant mailed me his fixes for making curl compile on Ultrix.

Daniel (24 February 2000):
- Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.

  I should also make a note here, if nothing else to myself, that when using
  the %-syntax for variables in DOS command prompts, you must use two %-
  letters for each one since that is an escape letter there! Maybe I should
  use another letter instead!

- Added more variables to -w:

  'http_code'
  'time_namelookup'
  'time_connect'
  'time_pretransfer'
  'url_effective'

- Made -w@filename read the syntax from a file and -w@- reads the syntax from
  stdin in the good old "standard" curl way.

Daniel (22 February 2000):
- Released a 6.5pre1 version to get some test and user feedback.

Daniel (21 February 2000):

- I added the -w/--write-out flag and some variables to go with it. -w is a
  single string, whatever you enter there will be written out when curl has
  completed a successful request. There are some variable substitutions and
  they are specified as '%{variable}' (without the quotes). Variables that
  exist as of this moment are:

        total_time     - total transfer time in seconds (with 2 decimals)
        size_download  - total downloaded amount of bytes
        size_upload    - total uploaded amount of bytes
        speed_download - the average speed of the entire download
        speed_upload   - the average speed of the entire upload

  I will of course add more variables, but I need input on these and others.

- It struck me that the -# progress bar will be hard to just apply on the new
  progress bar concept. I need some feedback on this before that'll get re-
  introduced! :-/

Daniel (16 February 2000):
- Jörn Hartroth brought me some fixes for the progress meter and I continued
  working on it. It seems to work for http download, http post, ftp download
  and ftp upload. It should be a pretty good test it works generally good.

- Still need to add the -# progress bar into the new style progress interface.

- Gonna have a go at my new output option parameter next.

Daniel (15 February 2000):
- The progress meter stuff is slowly taking place. There's more left before it
  is working ok and everything is tested, but we're reaching there. Slowly!

Daniel (11 February 2000):
- Paul Marquis fixed the config file parsing of curl to
  deal with any-length lines, removing the previous limit of 4K.

- Eetu Ojanen's suggestion of supporting the @-style for -b
  is implemented. Now -b@<filename> works as well as the old style. -b@- also
  similarly reads the cookies from stdin.

- Reminder: -D should not write to the file until it needs to, in the same way
  -o does. That would enable curl to use -b and -D on the same file...

- Ellis Pritchard made getdate.y work for MacOS X.

- Paul Harrington helped me out finding the crash in the
  cookie parser. He also pointed out curl's habit of sending empty cookies to
  the server.

Daniel (8 February 2000):
 - Ron Zapp corrected a problem in src/urlglob.c that
   prevented curl from getting compiled on sunos 4. The problem had to do
   with the difference in sprintf() return code types.

 - Transfer() should now be able to download and upload simultaneously. Let's
   do some progress meter fixes later this week.

Daniel (31 January 2000):
 - Paul Harrington found another core dump in the cookie
   parser. Curl doesn't properly recognize the 'version' keyword and I think
   that is what caused this. I need to refresh some specs on cookies and see
   what else curl lacks to improve this a bit more once and for all.

   RFC 2109 clearly specifies how cookies should be dealt with when they are
   compliant with that spec. I don't think many servers are though...

 - Mark W. Eichin found that while curl is uploading a form
   to a web site, it doesn't read incoming data why it'll hang after a while
   since the socket "pipe" becomes full.

   It took me two hours to rewrite Download() and Upload() into the new
   single function Transfer(). It even seems to work! More testing is required
   of course... I should get the header-sending together in a kind of queue
   and let them get "uploaded" in Transfer() as well.

 - Zhibiao Wu pointed out a curl bug in the location: area,
   although I did not get a reproducible way to do this why I have to wait
   with fixing anything.

 - Bob Schader suggested I should implement resume
   support for the HTTP PUT operation, and as I think it is a valid suggestion
   I'll work on it.

Daniel (25 January 2000):
 - M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
   corrected.

 - Jens Schleusener pointed out a problem to compile
   curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
   by Jörn's recent #include modifications!

Daniel (19 January 2000):
 - Oskar Liljeblad pointed out and corrected a problem
   in the Location: following system that made curl following a location: to a
   different protocol to fail.

   At January 31st I re-considered this fix and the surrounding source code. I
   could not really see that the patch did any difference, why I removed it
   again for further research and debugging. (It disabled location: following
   on server not running on default ports.)

 - Jörn Hartroth brought a fix that once again
   made it possible to select progress bar.

 - Jörn also fixed a few include problems.

Version 6.4

Daniel (17 January 2000):
 - Based on suggestions from Björn Stenberg, I made the
   progress deal better with larger files and added a "Time" field which shows
   the time spent on the download so far.
 - I'm now using the CVS repository on sourceforge.net, which also allows web
   browsing.

Daniel (10 January 2000):
 - Renumbered some enums in curl/curl.h since tag number 35 was used twice!
 - Added "postquote" support to the ftp section that enables post-ftp-transfer
   quote commands.
 - Now made the -Q/--quote parameter recognize '-' as a prefix, which means
   that command will be issued AFTER a successful ftp transfer. This can of
   course be used to delete or rename a file after it has been uploaded or
   downloaded. Use your imagination! ;-)
 - Since I do the main development on solaris 2.6 now, I had to download and
   install GNU groff to generate the hugehelp.c file. The solaris nroff cores
   on the man page! So, in order to make the solaris configure script find a
   better result I made gnroff get checked prior to the regular nroff.
 - Added all the curl exit codes to the man page.
 - Jim Gallagher properly tracked down a bug in autoconf
   2.13. The AC_CHECK_LIB() macro wrongfully uses the -l flag before the -L
   flag to 'ld' which causes the HP-UX 10.20 flavour to fail on all libchecks
   and therefore you can't make the configure script find the openssl libs!

Daniel (28 December 1999):
 - Tim Verhoeven correctly identified that curl
   doesn't support URL formatted file names when getting ftp. Now, there's a
   problem with getting very weird file names off FTP servers. RFC 959 defines
   that the file name syntax to use should be the same as in the native OS of
   the server. Since we don't know the peer server system we currently just
   translate the URL syntax into plain letters. It is still better and with
   the solaris 2.6-supplied ftp server it works with spaces in the file names.

Daniel (27 December 1999):
 - When curl parsed cookies straight off a remote site, it corrupted the input
   data, which, if the downloaded headers were stored made very odd characters
   in the saved data. Correctly identified and reported by Paul Harrington.

Daniel (13 December 1999):
 - General cleanups in the library interface. There had been some bad kludges
   added during times of stress and I did my best to clean them off. It was
   both regarding the lib API as well as include file confusions.

Daniel (3 December 1999):
 - A small --stderr bug was reported by Eetu Ojanen...

 - who also brought the suggestion of extending the -X flag to ftp list as
   well. So, now it is and the long option is now --request instead. It is
   only for ftp list for now (and the former http stuff too of course).

Lars J. Aas (24 November 1999):
 - Patched curl to compile and build under BeOS. Doesn't work yet though!

 - Corrected the Makefile.am files to allow putting object files in
   different directories than the sources.

Version 6.3.1

Daniel (23 November 1999):
 - I've had this major disk crash. My good old trust-worthy source disk died
   along with the machine that hosted it. Thank goodness most of all the
   things I've done are either backed up elsewhere or stored in this CVS
   server!

 - Michael S. Steuer pointed out a bug in the -F handling
   that made curl hang if you posted an empty variable such as '-F name='. It
   was one of those old bugs that never have worked properly...

 - Jason Baietto pointed out a general flaw in the HTTP
   download. Curl didn't complain if it was prematurely aborted before the
   entire download was completed. It does now.

Daniel (19 November 1999):
 - Chris Maltby very accurately criticized the lack of
   return code checks on the fwrite() calls. I did a thorough check for all
   occurrences and corrected this.

Daniel (17 November 1999):
 - Paul Harrington pointed out that the -m/--max-time option
   doesn't work for the slow system calls like gethostbyname()... I don't have
   any good fix yet, just a slightly less bad one that makes curl exit hard
   when the timeout is reached.

 - Bjorn Reese helped me point out a possible problem that might be the reason
   why Thomas Hurst experience problems in his Amiga version.

 Daniel (12 November 1999):
 - I found a crash in the new cookie file parser. It crashed when you gave
   a plain http header file as input...

Version 6.3

 Daniel (10 November 1999):
 - I kind of found out that the HTTP time-conditional GETs (-z) aren't always
   respected by the web server and the document is therefore sent in whole
   again, even though it doesn't match the requested condition. After reading
   section 13.3.4 of RFC 2616, I think I'm doing the right thing now when I do
   my own check as well. If curl thinks the condition isn't met, the transfer
   is aborted prematurely (after all the headers have been received).

 - After comments from Robert Linden I also rewrote some parts of the man page
   to better describe how the -F works.

 - Michael Anti put up a new curl download mirror in
   China:  http://www.pshowing.com/curl/

 - I added the list of download mirrors to the README file

 - I did add more explanations to the man page

 Daniel (8 November 1999):
 - I made the -b/--cookie option capable of reading netscape formatted cookie
   files as well as normal http-header files. It should be able to
   transparently figure out what kind of file it got as input.

 Daniel (29 October 1999):
 - Another one of Sebastiaan van Erk's ideas (that has been requested before
   but I seem to have forgotten who it was), is to add support for ranges in
   FTP downloads. As usual, one request is just a request, when they're two
   it is a demand. I've added simple support for X-Y style fetches. X has to
   be the lower number, though you may omit one of the numbers. Use the -r/
   --range switch (previously HTTP-only).

 - Sebastiaan van Erk suggested that curl should be
   able to show the file size of a specified file. I think this is a splendid
   idea and the -I flag is now working for FTP. It displays the file size in
   this manner:
        Content-Length: XXXX
   As it resembles normal headers, and leaves us the opportunity to add more
   info in that display if we can come up with more in the future! It also
   makes sense since if you access ftp through a HTTP proxy, you'd get the
   file size the same way.

   I changed the order of the QUOTE command executions. They're now executed
   just after the login and before any other command. I made this to enable
   quote commands to run before the -I stuff is done too.

 - I found out that -D/--dump-header and -V/--version weren't documented in
   the man page.

 - Many HTTP/1.1 servers do not support ranges. Don't ask me why. I did add
   some text about this in the man page for the range option. The thread in
   the mailing list that started this was initiated by Michael Anti.

 - I get reports about nroff crashes on solaris 2.6+ when displaying the curl
   man page. Switch to gnroff instead, it is reported to work(!). Adam Barclay
   reported and brought the suggestion.

 - In a dialogue with Johannes G. Kristinsson we came
   up with the idea to let -H/--header specified headers replace the
   internally generated headers, if you happened to select to add a header
   that curl normally uses by itself. The advantage with this is not entirely
   obvious, but in Johannes' case it means that he can use another Host: than
   the one curl would set.

 Daniel (27 October 1999):
 - Jongki Suwandi brought a nice patch for (yet another) crash when following
   a location:. This time you had to follow a https:// server's redirect to
   get the core.

Version 6.2

 Daniel (21 October 1999):
 - I think I managed to remove the suspicious (nil) that has been seen just
   before the "Host:" in HTTP requests when -v was used.
 - I found out that if you followed a location: when using a proxy, without
   having specified http:// in the URL, the protocol part was added once again
   when moving to the next URL! (The protocol part has to be added to the
   URL when going through a proxy since it has no protocol-guessing system
   such as curl has.)
 - Benjamin Ritcey reported a core dump under solaris 2.6
   with OpenSSL 0.9.4. It turned out this was due to a bad free() in main.c
   that occurred after the download was done and completed.
 - Benjamin found ftp downloads to show the first line of the download meter
   to get written twice, and I removed that problem. It was introduced with
   the multiple URL support.
 - Dan Zitter correctly pointed out that curl 6.1 and earlier versions didn't
   honor RFC 2616 chapter 4 section 2, "Message Headers": "...Field names are
   case-insensitive..."  HTTP header parsing assumed a certain casing. Dan
   also provided me with a patch that corrected this, which I took the liberty
   of editing slightly.
 - Dan Zitter also provided a nice patch for config.guess to better recognize
   the Mac OS X
 - Dan also corrected a minor problem in the lib/Makefile that caused linking
   to fail on OS X.

 Daniel (19 October 1999):
 - Len Marinaccio came up with some problems with curl.  Since Windows has a
   crippled shell, it can't redirect stderr and that causes trouble. I added
   --stderr today which allows the user to redirect the stderr stream to a
   file or stdout.

 Daniel (18 October 1999):
 - The configure script now understands the '--without-ssl' flag, which now
   totally disable SSL/https support. Previously it wasn't possible to force
   the configure script to leave SSL alone. The previous functionality has
   been retained. Troy Engel helped test this new one.

Version 6.1 (October 17 1999)

 Daniel (17 October 1999):
 - I ifdef'ed or commented all the zlib stuff in the sources and configure
   script. It turned out we needed to mock more with zlib than I initially
   thought, to make it capable of downloading compressed HTTP documents and
   uncompress them on the fly. I didn't mean the zlib parts of curl to become
   more than minor so this means I halt the zlib expedition for now and wait
   until someone either writes the code or zlib gets updated and better
   adjusted for this kind of usage.  I won't get into details here, but a
   short a summary is suitable:
   - zlib can't automatically detect whether to use zlib or gzip
     decompression methods.
   - zlib is very neat for reading gzipped files from a file descriptor,
     although not as nice for reading buffer-based data such as we would
     want it.
   - there are still some problems with the win32 version when reading from
     a file descriptor if that is a socket

 Daniel (14 October 1999):
 - Moved the (external) include files for libcurl into a subdirectory named
   curl and adjusted all #include lines to use <curl/XXXX> to maintain a
   better name space and control of the headers. This has been requested.

 Daniel (12 October 1999):
 - I modified the 'maketgz' script to perform a 'make' too before a release
   archive is put together in an attempt to make the time stamps better and
   hopefully avoid the double configure-running that use to occur.

 Daniel (11 October 1999):
 - Applied Jörn's patches that fixes zlib for mingw32 compiles as well as
   some other missing zlib #ifdef and more text on the multiple URL docs in
   the man page.

Version 6.1beta

 Daniel (6 October 1999):
 - Douglas E. Wegscheid sent me a patch that made the exact same thing as I
   just made: the -d switch is now capable of reading post data from a named
   file or stdin.  Use it similarly to the -F. To read the post data from a
   given file:

        curl -d @path/to/filename www.postsite.com

   or let curl read it out from stdin:

        curl -d @- www.postit.com

 Jörn Hartroth (3 October 1999):
 - Brought some more patches for multiple URL functionality. The MIME
   separation ideas are almost scrapped now, and a custom separator is being
   used instead. This is still compile-time "flagged".

 Daniel
 - Updated curl.1 with multiple URL info.

 Daniel (30 September 1999):
 - Felix von Leitner brought openssl-check fixes for configure.in to work
   out-of-the-box when the openssl files are installed in the system default
   dirs.

 Daniel (28 September 1999)
 - Added libz functionality. This should enable decompressing gzip, compress
   or deflate encoding HTTP documents. It also makes curl send an accept that
   it accepts that kind of encoding. Compressed contents usually shortens
   download time. I *need* someone to tell me a site that uses compressed HTTP
   documents so that I can test this out properly.

 - As a result of the adding of zlib awareness, I changed the version string
   a little. I plan to add openldap version reporting in there too.

 Daniel (17 September 1999)
 - Made the -F option allow stdin when specifying files. By using '-' instead
   of file name, the data will be read from stdin.

Version 6.0 (September 14 1999)

 Daniel (13 September 1999)
 - Added -X/--http-request <request> to enable any HTTP command to be sent.
   Do not that your server has to support the exact string you enter. This
   should possibly a string like DELETE or TRACE.

 - Applied Douglas' mingw32-fixes for the makefiles.

 Daniel (10 September 1999)
 - Douglas E. Wegscheid pointed out a problem. Curl didn't check the FTP
   servers return code properly after the --quote commands were issued. It
   took anything non 200 as an error, when all 2XX codes should be accepted as
   OK.

 - Sending cookies to the same site in multiple lines like curl used to do
   turned out to be bad and breaking the cookie specs. Curl now sends all
   cookies on a single Cookie: line. Curl is not yet RFC 2109 compliant, but I
   doubt that many servers do use that syntax (yet).

 Daniel (8 September 1999)
 - Jörn helped me make sure it still compiles nicely with mingw32 under win32.

 Daniel (7 September 1999)
 - FTP upload through proxy is now turned into a HTTP PUT. Requested by
   Stefan Kanthak.

 - Added the ldap files to the .m32 makefile.

 Daniel (3 September 1999)
 - Made cookie matching work while using HTTP proxy.

 Bjorn Reese (31 August 1999)
 - Passed his ldap:// patch. Note that this requires the openldap shared
   library to be installed and that LD_LIBRARY_PATH points to the
   directory where the lib will be found when curl is run with a
   ldap:// URL.

 Jörn Hartroth (31 August 1999)
 - Made the Mingw32 makefiles into single files.
 - Made file:// work for Win32. The same code is now used for unix as well for
   performance reasons.

 Douglas E. Wegscheid (30 August 1999)
 - Patched the Mingw32 makefiles for SSL builds.

 Matthew Clarke (30 August 1999)
 - Made a cool patch for configure.in to allow --with-ssl to specify the
   root dir of the openssl installation, as in

        ./configure --with-ssl=/usr/ssl_here

 - Corrected the 'reconf' script to work better with some shells.

 Jörn Hartroth (26 August 1999)
 - Fixed the Mingw32 makefiles in lib/ and corrected the file.c for win32
   compiles.

Version 5.11

 Daniel (25 August 1999)
 - John Weismiller pointed out a bug in the header-line
   realloc() system in download.c.

 - I added lib/file.[ch] to offer a first, simple, file:// support. It
   probably won't do much good on win32 system at this point, but I see it
   as a start.

 - Made the release archives get a Makefile in the root dir, which can be
   used to start the compiling/building process easier. I haven't really
   changed any INSTALL text yet, I wanted to get some feed-back on this
   first.

 Daniel (17 August 1999)
 - Another Location: bug. Curl didn't do proper relative locations if the
   original URL had cgi-parameters that contained a slash. Nusu's page
   again.

 - Corrected the NO_PROXY usage. It is a list of substrings that if one of
   them matches the tail of the host name it should connect to, curl should
   not use a proxy to connect there. Pointed out to me by Douglas
   E. Wegscheid.  I also changed the README text a little regarding this.

 Daniel (16 August 1999)
 - Fixed a memory bug with http-servers that sent Location: to a Location:
   page. Nusu's page showed this too.

 - Made cookies work a lot better. Setting the same cookie name several times
   used to add more cookies instead of replacing the former one which it
   should've. Nusu <nus at intergorj.ro> brought me an URL that made this
   painfully visible...

 Troy (15 August 1999)
 - Brought new .spec files as well as a patch for configure.in that lets the
   configure script find the openssl files better, even when the include
   files are in /usr/include/openssl

Version 5.10

 Daniel (13 August 1999)
 - SSL_CTX_set_default_passwd_cb() has been modified in the 0.9.4 version of
   OpenSSL. Now why couldn't they simply add a *new* function instead of
   modifying the parameters of an already existing function? This way, we get
   a compiler warning if compiling with 0.9.4 but not with earlier. So, I had
   to come up with a #if construction that deals with this...

 - Made curl output the SSL version number get displayed properly with 0.9.4.

 Troy (12 August 1999)
 - Added MingW32 (GCC-2.95) support under Win32. The INSTALL file was also
   a bit rearranged.

 Daniel (12 August 1999)
 - I had to copy a good <arpa/telnet.h> include file into the curl source
   tree to enable the silly win32 systems to compile. The distribution rights
   allows us to do that as long as the file remains unmodified.

 - I corrected a few minor things that made the compiler complain when
   -Wall -pedantic was used.

 - I'm moving the official curl web page to curl.haxx.nu. I think it
   will make it easier to remember as it is a lot shorter and less cryptic.
   The old one still works and shows the same info.

 Daniel (11 August 1999)
 - Albert Chin-A-Young mailed me another correction for NROFF in the
   configure.in that is supposed to be better for IRIX users.

 Daniel (10 August 1999)
 - Albert Chin-A-Young helped me with some stupid Makefile things, as well as
   some fiddling with the getdate.c stuff that he had problems with under
   HP-UX v10. getdate.y will now be compiled into getdate.c if the appropriate
   yacc or bison is found by the configure script. Since this is slightly new,
   we need to test the output getdate.c with win32 systems to make sure it
   still compiles there.

 Daniel (5 August 1999)
 - I've just setup a new mailing list with the intention to keep discussions
   around libcurl development in it. I mainly expect it to be for thoughts and
   brainstorming around a "next generation" library, rather than nitpicking
   about the current implementation or details in the current libcurl.

   To join our happy bunch of future-looking geeks, enter 'subscribe
   <address>' in the body of a mail and send it to
   libcurl-request@listserv.fts.frontec.se.  Curl bug reports, the usual curl
   talk and everything else should still be kept in this mailing list. I've
   started to archive this mailing list and have put the libcurl web page at
   www.fts.frontec.se/~dast/libcurl/.

 - Stefan Kanthak contacted me regarding a few problems in the configure
   script which he discovered when trying to make curl compile and build under
   Siemens SINIX-Z V5.42B2004!

 - Marcus Klein very accurately informed me that src/version.h was not present
   in the CVS repository. Oh, how silly...

 - Linus Nielsen rewrote the telnet:// part and now curl offers limited telnet
   support. If you run curl like 'curl telnet://host' you'll get all output on
   the screen and curl will read input from stdin. You'll be able to login and
   run commands etc, but since the output is buffered, expect to get a little
   weird output.

   This is still in its infancy and it might get changed. We need your
   feed-back and input in how this is best done.

   WIN32 NOTE: I bet we'll get problems when trying to compile the current
   lib/telnet.c on win32, but I think we can sort them out in time.

 - David Sanderson reported that FORCE_ALLOCA_H or HAVE_ALLOCA_H must be
   defined for getdate.c to compile properly on HP-UX 11.0. I updated the
   configure script to check for alloca.h which should make it.

 Daniel (4 August 1999)
 - I finally got to understand Marcus Klein's ftp download resume problem,
   which turns out to be due to different outputs from different ftp
   servers. It makes ftp download resuming a little trickier, but I've made
   some modifications I really believe will work for most ftp servers and I do
   hope you report if you have problems with this!

 - Added text about file transfer resuming to README.curl.

 Daniel (2 August 1999)
 - Applied a progress-bar patch from Lars J. Aas. It offers
   a new styled progress bar enabled with -#/--progress-bar.

 T. Yamada <tai at imasy.or.jp> (30 July 1999)
 - It breaks with segfault when 1) curl is using .netrc to obtain
   username/password (option '-n'), and 2) is automatically redirected to
   another location (option '-L').

   There is a small bug in lib/url.c (block starting from line 641), which
   tries to take out username/password from user- supplied command-line
   argument ('-u' option). This block is never executed on first attempt since
   CONF_USERPWD bit isn't set at first, but curl later turns it on when it
   checks for CONF_NETRC bit. So when curl tries to redo everything due to
   redirection, it segfaults trying to access *data->userpwd.

Version 5.9.1

 Daniel (30 July 1999)
 - Steve Walch pointed out that there is a memory leak in the formdata
   functions. I added a FormFree() function that is now used and supposed to
   correct this flaw.

 - Mark Wotton reported:
   'curl -L https://www.cwa.com.au/' core dumps.  I managed to cure this by
   correcting the cleanup procedure. The bug seems to be gone with my OpenSSL
   0.9.2b, although still occurs when I run the ~100 years old SSLeay 0.8.0. I
   don't know whether it is curl or SSLeay that is to blame for that.

 - Marcus Klein:
   Reported an FTP upload resume bug that I really can't repeat nor understand.
   I leave it here so that it won't be forgotten.

 Daniel (29 July 1999)
 - Costya Shulyupin suggested support for longer URLs when following Location:
   and I could only agree and fix it!

 - Leigh Purdie found a problem in the upload/POST department. It turned out
   that http.c accidentaly cleared the pointer instead of the byte counter
   when supposed to.

 - Costya Shulyupin pointed out a problem with port numbers and Location:. If
   you had a server at a non-standard port that redirected to an URL using a
   standard port number, curl still used that first port number.

 - Ralph Beckmann pointed out a problem when using both CONF_FOLLOWLOCATION
   and CONF_FAILONERROR simultaneously. Since the CONF_FAILONERROR exits on
   the 302-code that the follow location header outputs it will never show any
   html on location: pages. I have now made it look for >=400 codes if
   CONF_FOLLOWLOCATION is set.

 - 'struct slist' is now renamed to 'struct curl_slist' (as suggested by Ralph
   Beckmann).

 - Joshua Swink and Rick Welykochy were the first to point out to me that the
   latest OpenSSL package now have moved the standard include path. It is now
   in /usr/local/ssl/include/openssl and I have now modified the --enable-ssl
   option for the configure script to use that as the primary path, and I
   leave the former path too to work with older packages of OpenSSL too.

 Daniel (9 June 1999)
 - I finally understood the IRIX problem and now it seem to compile on it!
   I am gonna remove those #define strcasecmp() things once and for all now.

 Daniel (4 June 1999)
 - I adjusted the FTP reply 227 parser to make the PASV command work better
   with more ftp servers. Appearantly the Roxen Challanger server replied
   something curl 5.9 could deal with! :-( Reported by Ashley Reid-Montanaro
   and Mark Butler brought a solution for it.

 Daniel (26 May 1999)
 - Rearranged. README is new, the old one is now README.curl and I added a
   README.libcurl with text I got from Ralph Beckmann.

 - I also updated the INSTALL text.

 Daniel (25 May 1999)
 - David Jonathan Lowsky correctly pointed out that curl didn't properly deal
   with form posting where the variable shouldn't have any content, as in curl
   -F "form=" www.site.com. It was now fixed.

Version 5.9 (May 22 1999)

 Daniel (22 May 1999)
 - I've got a bug report from Aaron Scarisbrick in which he states he has some
   problems with -L under FreeBSD 3.0. I have previously got another bug
   report from Stefan Grether which points at an error with similar sympthoms
   when using win32. I made the allocation of the new url string a bit faster
   and different, don't know if it actually improves anything though...

 Daniel (20 May 1999)
 - Made the cookie parser deal with CRLF newlines too.

 Daniel (19 May 1999)
 - Download() didn't properly deal with failing return codes from the sread()
   function. Adam Coyne found the problem in the win32 version, and Troy Engel
   helped me out isolating it.

 Daniel (16 May 1999)
 - Richard Adams pointed out a bug I introduced in 5.8. --dump-header doesn't
   work anymore! :-/ I fixed it now.

 - After a suggestion by Joshua Swink I added -S / --show-error to force curl
   to display the error message in case of an error, even if -s/--silent was
   used.

 Daniel (10 May 1999)
 - I moved the stuff concerning HTTP, DICT and TELNET it their own source
   files now. It is a beginning on my clean-up of the sources to make them
   layer all those protocols better to enable more to be added easier in the
   future!

 - Leon Breedt sent me some files I've not put into the main curl
   archive. They're for creating the Debian package thingie. He also sent me a
   debian package that I've made available for download at the web page

 Daniel (9 May 1999)
 - Made it compile on cygwin too.

 Troy Engel (7 May 1999)
 - Brought a series of patches to allow curl to compile smoothly on MSVC++ 6
   again!

 Daniel (6 May 1999)
 - I changed the #ifdef HAVE_STRFTIME placement for the -z code so that it
   will be easier to discover systems that don't have that function and thus
   can't use -z successfully. Made the strftime() get used if WIN32 is defined
   too.

Version 5.8

 Daniel (5 May 1999)
 - I've had it with this autoconf/automake mess. It seems to work allright
   for most people who don't have automake installed, but for those who have
   there are problems all over.

   I've got like five different bug reports on this only the last
   week... Claudio Neves and Federico Bianchi and root <duggerj001 at
   hawaii.rr.com> are some of them reporting this.

   Currently, I have no really good fix since I want to use automake myself to
   generate the Makefile.in files. I've found out that the @SHELL@-problems
   can often be fixed by manually invoking 'automake' in the archive root
   before you run ./configure... I've hacked my maketgz script now to fiddle
   a bit with this and my tests seem to work better than before at least!

 Daniel (4 May 1999)
 - mkhelp.pl has been doing badly lately. I corrected a case problem in
   the regexes.

 - I've now remade the -o option to not touch the file unless it needs to.
   I had to do this to make -z option really fine, since now you can make a
   curl fetch and use a local copy's time when downloading to that file, as
   in:

        curl -z dump -o dump remote.site.com/file.html

   This will only get the file if the remote one is newer than the local.
   I'm aware that this alters previous behaviour a little. Some scripts out
   there may depend on that the file is always touched...

 - Corrected a bug in the SSLv2/v3 selection.

 - Felix von Leitner requested that curl should be able to send
   "If-Modified-Since" headers, which indeed is a fair idea.  I implemented it
   right away! Try -z <expression> where expression is a full GNU date
   expression or a file name to get the date from!

 Stephan Lagerholm (30 Apr 1999)
 - Pointed out a problem with the src/Makefile for FreeBSD. The RM variable
   isn't set and causes the make to fail.

 Daniel (26 April 1999)
 - Am I silly or what? Irving Wolfe pointed out to me that the curl version
   number was not set properly. Hasn't been since 5.6. This was due to a bug
   in my maketgz script!

 David Eriksson (25 Apr 1999)
 - Found a bug in cookies.c that made it crash at times.

Version 5.7.1

 Doug Kaufman (23 Apr 1999)
 - Brought two sunos 4 fixes. One of them being the hostip.c fix mentioned
   below and the other one a correction in include/stdcheaders.h

 - Added a paragraph about compiling with the US-version of openssl to the
   INSTALL file.

 Daniel
 - New mailing list address. Info updated on the web page as well as in the
   README file

 Greg Onufer (20 Apr 1999)
 - hostip.c didn't compile properly on SunOS 5.5.1.
   It needs an #include <sys/types.h>

Version 5.7

 Daniel (Apr 20 1999)
 - Decided to upload a non-beta version right now!

 - Made curl support any-length HTTP headers. The destination buffer is now
   simply enlarged every time it turns out to be too small!

 - Added the FAQ file to the archive. Still a bit smallish, but it is a
   start.

 Eric Thelin (15 Apr 1999)
 - Made -D accept '-' instead of filename to write to stdout.

Version 5.6.3beta

 Daniel (Apr 12 1999)

 - Changed two #ifdef WIN32 to better #ifdef <errorcode> when connect()ing
   in url.c and ftp.c. Makes cygwin32 deal with them better too. We should
   try to get some decent win32-replacement there. Anyone?

 - The old -3/--crlf option is now ONLY --crlf!

 - I changed the "SSL fix" to a more lame one, but that doesn't remove as
   much functionality. Now I've enabled the lib to select what SSL version it
   should try first. Appearantly some older SSL-servers don't like when you
   talk v3 with them so you need to be able to force curl to talk v2 from the
   start. The fix dated April 6 and posted on the mailing list forced curl to
   use v2 at all times using a modern OpenSSL version, but we don't really
   want such a crippled solution.

 - Marc Boucher sent me a patch that corrected a math error for the
   "Curr.Speed" progress meter.

 - Eric Thelin sent me a patch that enables '-K -' to read a config file from
   stdin.

 - I found out we didn't close the file properly before so I added it!

 Daniel (Apr 9 1999)
 - Yu Xin pointed out a problem with ftp download resume.  It didn't work at
   all! ;-O

 Daniel (Apr 6 1999)
 - Corrected the version string part generated for the SSL version.

 - I found a way to make some other SSL page work with openssl 0.9.1+ that
   previously didn't (ssleay 0.8.0 works with it though!). Trying to get
   some real info from the OpenSSL guys to see how I should do to behave the
   best way. SSLeay 0.8.0 shouldn't be that much in use anyway these days!

Version 5.6.2beta

 Daniel (Apr 4 1999)
 - Finally have curl more cookie "aware". Now read carefully. This is how
   it works.
   To make curl read cookies from an already existing file, in plain header-
   format (like from the headers of a previous fetch) invoke curl with the
   -b flag like:

        curl -b file http://site/foo.html

   Curl will then use all cookies it finds matching. The old style that sets
   a single cookie with -b is still supported and is used if the string
   following -b includes a '=' letter, as in "-b name=daniel".

   To make curl read the cookies sent in combination with a location: (which
   sites often do) point curl to read a non-existing file at first (i.e
   to start with no existing cookies), like:

        curl -b nowhere http://site/setcookieandrelocate.html

 - Added a paragraph in the TODO file about the SSL problems recently
   reported. Evidently, some kind of SSL-problem curl may need to address.

 - Better "Location:" following.

 Douglas E. Wegscheid (Tue, 30 Mar 1999)
 - A subsecond display patch.

 Daniel (Mar 14 1999)
 - I've separated the version number of libcurl and curl now. To make
   things a little easier, I decided to start the curl numbering from
   5.6 and the former version number known as "curl" is now the one
   set for libcurl.

 - Removed the 'enable-no-pass' from configure, I doubt anyone wanted
   that.

 - Made lots of tiny adjustments to compile smoothly with cygwin under
   win32. It's a killer for porting this to win32, bye bye VC++! ;-)
   Compiles and builds out-of-the-box now. See the new wordings in
   INSTALL for details.

 - Beginning experiments with downloading multiple document from a http
   server while remaining connected.

Version 5.6beta

 Daniel (Mar 13 1999)
 - Since I've changed so much, I thought I'd just go ahead and implement the
   suggestion from Douglas E. Wegscheid. -D or --dump-header is now storing
   HTTP headers separately in the specified file.

 - Added new text to INSTALL on what to do to build this on win32 now.

 - Aaargh. I had to take a step back and prefix the shared #include files
   in the sources with "../include/" to please VC++...

 Daniel (Mar 12 1999)
 - Split the url.c source into many tiny sources for better readability
   and smaller size.

 Daniel (Mar 11 1999)
 - Started to change stuff for a move to make libcurl and a more separate
   curl application that uses the libcurl. Made the libcurl sources into
   the new lib directory while the curl application will remain in src as
   before. New makefiles, adjusted configure script and so.

   libcurl.a built quickly and easily. I better make a better interface to
   the lib functions though.

   The new root dir include/ is supposed to contain the public information
   about the new libcurl. It is a little ugly so far :-)


 Daniel (Mar 1 1999)
 - Todd Kaufmann sent me a good link to Netscape's cookie spec as well as the
   info that RFC 2109 specifies how to use them.  The link is now in the
   README and the RFC in the RESOURCES.

 Daniel (Feb 23 1999)
 - Finally made configure accept --with-ssl to look for SSL libs and includes
   in the "standard" place /usr/local/ssl...

 Daniel (Feb 22 1999)
 - Verified that curl linked fine with OpenSSL 0.9.1c which seems to be
   the most recent.

 Henri Gomez (Fri Feb  5 1999)
 - Sent in an updated curl-ssl.spec. I still miss the script that builds an
   RPM automatically...

Version 5.5.1

 Mark Butler (27 Jan 1999)
 - Corrected problems in Download().

 Danitel Stenberg (25 Jan 1999)
 - Jeremie Petit pointed out a few flaws in the source that prevented it from
   compile warning free with the native compiler under Digital Unix v4.0d.

Version 5.5

 Daniel Stenberg (15 Jan 1999)
 - Added Bjorns small text to the README about the DICT protocol.

 Daniel Stenberg (11 Jan 1999)
 - <jswink at softcom.net> reported about the win32-versioin: "Doesn't use
   ALL_PROXY environment variable". Turned out to be because of the static-
   buffer nature of the win32 environment variable calls!

 Bjorn Reese (10 Jan 1999)
 - I have attached a simple addition for the DICT protocol (RFC 2229).
   It performs dictionary lookups. The output still needs to be better
   formatted.

   To test it try (the exact format, and more examples are described in
   the RFC)

        dict://dict.org/m:hello
        dict://dict.org/m:hello::soundex


 Vicente Garcia (10 Jan 1999)
 - Corrected the progress meter for files larger than 20MB.

 Daniel Stenberg (7 Jan 1999)
 - Corrected the -t and -T help texts. They claimed to be FTP only.

Version 5.4

 Daniel Stenberg
 (7 Jan 1999)
 - Irving Wolfe reported that curl -s didn't always supress the progress
   reporting. It was the form post that autoamtically always switched it on
   again. This is now corrected!

 (4 Jan 1999)
 - Andreas Kostyrka suggested I'd add PUT and he helped me out to test it. If
   you use -t or -T now on a http or https server, PUT will be used for file
   upload.

   I removed the former use of -T with HTTP. I doubt anyone ever really used
   that.

 (4 Jan 1999)
 - Erik Jacobsen found a width bug in the mprintf() function.  I corrected it
   now.

 (4 Jan 1999)
 - As John V. Chow pointed out to me, curl accepted very limited URL sizes. It
   should now accept path parts that are up to at least 4096 bytes.

 - Somehow I screwed up when applying the AIX fix from Gilbert Ramirez, so
   I redid that now.

Version 5.3a (win32 only)

 Troy Engel
 - Corrected a win32 bug in the environment variable part.

Version 5.3

 Gilbert Ramirez Jr. (21 Dec 1998)
 - I have implemented the "quote" function of FTP clients. It allows you to
   send arbitrary commands to the remote FTP server. I chose the -Q/--quote
   command-line arguments.

   You can have more than one quoted string, and curl will apply them in
   order.  This is what I use for my MVS upload:

  curl -B --crlf -Q "site lrecl=80" -Q "site blk=8000" -T file ftp://os390/test

   Curl will send the two quoted "site" commands in the proper order.

 - Made it compile smoothly on AIX.

 Gilbert Ramirez Jr. (18 Dec 1998)
 - Brought an MVS patch: -3/--mvs, for ftp upload to the MVS ftp server.

 Troy Engel (17 Dec 1998)
 - Brought a correction that fixes the win32 curl bug.

 Daniel Stenberg
 - A bug, pointed out to me by Dr H. T. Leung, caused curl to crash on the -A
   flag on certain systems. Actually, all systems should've!

 - Added a few defines to make directories/file names get build nicer (with _
   instead of . and \ instead of / in win32).

 - steve <fisk at polar.bowdoin.edu> reported a weird bug that occured if the
   ftp server response line had a parenthesis on the line before the (size)
   info. I hope it works better now!

Version 5.2.1

 Steven G. Johnson (Dec 14, 1998)
 - Brought a fix that corrected a crash in 5.2 due to bad treatment of the
   environment variables.

Version 5.2

 Daniel Stenberg (Dec 14, 1998)
 - Rewrote the mkhelp script and now, the mkhelp.pl script generates the
   hugehelp.c file from the README *and* the man page file curl.1. By using
   both files, I no longer need to have double information in both the man
   page and the README as well. So, win32-users will only have the hugehelp.c
   file for all info, but then, they download the plain binary most times
   anyway.

 - gcc2.8.1 with the -Wall flag complaints a lot on subscript has type `char'
   if I don't explicitly typecast the argument to isdigit() or isspace() to
   int. So I did to compile warning free with that too.

 - Added checks for 'long double' and 'long long' in the configure script. I
   need those for the mprintf.c source to compile well on non long long
   comforming systems!

Version 5.1 (not publicly released)

 Daniel Stenberg (Dec 10, 1998)
 - I got a request for a pre-compiled NT Alpha version. Anyone?

 - Added Lynx/CERN www lib proxy environment variable support. That means curl
   now reads and understands the following environment variables:

	HTTP_PROXY, HTTPS_PROXY, FTP_PROXY, GOPHER_PROXY

   They should be set for protocol-specific proxies. General proxy should be
   set with

	ALL_PROXY

   And a comma-separated list of host names that shouldn't go through any
   proxy is set in (only an asterisk, '*' matches all hosts).

	NO_PROXY

   The usage of the -x/--proxy flag overrides the environment variables.

 - Proxy can now be specified with a procotol:// prefix.

 - Wrote the curl.1 man page.

 - Introduced a whole new dynamic buffer system for all sprintf()s. It is
   based on the *printf() package by yours truly and Bjorn Reese. Hopefully,
   there aren't that many buffer overflow risks left now.

 - Ah, I should mention I've compiled and built curl successfully under
   solaris 2.6 with gcc now, gcc 2.7.2 won't work but 2.8.1 did ok.

 Oren Tirosh (Dec 3, 1998)
 - Brought two .spec files, to use when creating (Linux) Redhat style RPM
   packages. They're named curl.spec and curl-ssl.spec.

 Troy Engel
 - Supplied the src/Makefile.vc6 for easy compiling with VC++ under Win32.

Version 5.0

 Daniel Stenberg (Dec 1, 1998)
 - Not a single bug report in ages.
 - Corrected getpass.c and main.c to compile warning and error free with the
   Win32 VC++ crap.

Version 5.0 beta 24

 Daniel Stenberg (Nov 20, 1998)

 HOW TO BUILD A RELEASE ARCHIVE:

 * Pre-requisite software:
   What		     To build what             Reads data from
   ====              =============             ===============
   GNU automake      Makefile.in, aclocal.m4   configure.in
     GNU make(1)      - " -
     GNU gcc(1)       - " -
   GNU autoconf      configure                 configure.in
   GNU autoheader(2) config.h.in	       configure.in, acconfig.h

 * Make sure all files that should be part of the archive are put in FILES.

 * Run './maketgz' and enter version number of the new to become archive.

   maketgz does:

   - Enters the newly created version number in url.h.
   - (If you don't have automake, this script will warn about that, but unless
     you have changed the Makefile.am files, that is nothing to care about.)
     If you have it, it'll run it.
   - If you have autoconf, the configure.in will be edited to get the newly
     created version number and autoconf will be run.
   - Creates a new directory named curl-<version>. (Actually, it uses the base
     name of the current directory up to the first '-'.)
   - Copies all files mentioned in FILES to the new directory. Saving
     permissions and directory structure.
   - Uses tar to create an archive of it all, named curl-<version>.tar.gz
   - gzips the archive
   - Removes the new directory and all its contents.

 * When done, you have an archive stored in your directory named
   curl-<version>.tar.gz.

   Done!

   (1) They're required to make automake run properly.
   (2) It is distributed as a part of the GNU autoconf archive.

 Daniel Stenberg (Nov 18, 1998)
 - I changed the TAG-system. If you ever used urlget() from this package in
   another product, you need to recompile with the new headers. I did this
   new stuff to better deal with different compilers and system with different
   variable sizes. I think it makes it a little more portable. This proves
   to compile warning free with the problematic IRIX compiler!
 - Win32 compiled with a silly error. Corrected now.
 - Brian Chaplin reported yet another problem in
   multiline FTP responses. I've tried to correct it. I mailed him a new
   version and I hope he gets back soon with positive feedback!
 - Improved the 'maketgz' to create a temporary directory tree which it makes
   an archive from instead of the previous renaming of the current one.
 - Mailing list opened (see README).
 - Made -v more verbose on the PASV section of ftp transfers. Now it tells
   host name and IP of the new host (and port number). I also added a section
   about PORT vs PASV in the README.

Version 5.0 beta 21

 Angus Mackay (Nov 15, 1998)
 - Introduced automake stuff.

 Daniel Stenberg (Nov 13, 1998)
 - Just made a successful GET of a document from an SSL-server using my own
   private certificate for authentication! The certificate has to be in PEM
   format. You do that the easiest way (although not *that* easy) by
   downloading the SSLyeay PKCS#12-patch by Dr Stephen N. Henson from his site
   at: http://www.drh-consultancy.demon.co.uk/. Using his tool, you can
   convert any modern Netscape or (even) MSIE certificate to PEM-format.  Use
   it with 'curl -E <certificate:password> https://site.com'.  If this isn't a
   cool feature, then I don't know what cool features look like! ;-)
 - Working slowly on telnet connections. #define TRY_TELNET to try it out.
   (curl -u user:passwd "telnet://host.com/cat .login" is one example) I do
   have problem to define how it should work. The prime purpose for this must
   be to get (8bit clean) files via telnet, and it really isn't that easy to
   get files this way. Still having problems with \n being converted to \r\n.

 Angus Mackay (Nov 12, 1998)
 - Corrected another bug in the long parameter name parser.
 - Modified getpass.c (NOTE: see the special licensing in the top of that
   source file).

 Daniel Stenberg (Nov 12, 1998)
 - We may have removed the silly warnings from url.c when compiled under IRIX.
   Thanks again to Bjorn Reese and Martin Staael.
 - Wrote formfind.pl which is a new perl script intended to help you find out
   how a FORM submission should be done. This needs a little more work to get
   really good.

 Daniel Stenberg (Nov 11, 1998)
 - Made the HTTP header-checker accept white spaces before the HTTP/1.? line.
   Appearantly some proxies/sites add such at times (my test proxy did when I
   downloaded a gopher page with it)!
 - Moved the former -h to -M and made -h show the short help text instead. I
   had to enable a forced help text option. Now an even shorter help text will
   be presented when an unknown option and similar, is used.
 - stdcheaders.h didn't work with IRIX 6.4 native cc compiler. I hope my
   changes don't make other versions go nuts instead.

 Daniel Stenberg (Nov 10, 1998)
 - Added a weird check in the configure script to check for the silly AIX
   warnings about my #define strcasecmp() stuff. I do that define to prevent
   me and other contributors to accidentaly use that function name instead
   of strequal()...
 - I bugfixed Angus's getpass.c very little.
 - Fixed the verbose flag names to getopt-style, i.e 'curl --loc' will be
   sufficient instead of --location as "loc" is a unique prefix. Also, anything
   after a '--' is treated as an URL. So if you do have a host with a weeeird
   name you can do 'curl -- -host.com'.
 - Another getopt-adjust; curl now accepts flags after the URL on the command
   line. 'curl www.foo.com -O' is perfectly valid.
 - Corrected the .curlrc parser so that strtok() is no longer used and I
   believe it works better. Even URLs can be specified in it now.

 Angus Mackay (Nov 9, 1998)
 - Replaced getpass.c with a newly written one, not under GPL license
 - Changed OS to a #define in config.h instead of compiler flag
 - Makefile now uses -DHAVE_CONFIG_H

 Daniel Stenberg (Nov 9, 1998)
 - Ok, I expanded the tgz-target to update the version string on each occation
   I build a release archive!
 - I reacted on Angus Mackay's initiative and remade the parameter parser to
   be more getopt compliant. Curl now supports "merged" flags as in
	curl -lsv ftp.site.com
   Do note that I had to move three short-names of the options. Parameters
   that needs an additional string such as -x must be stand-alone or the
   last in a merged sequence:
	curl -lsx my-proxy ftp.site.com
   is ok, but using the flags in a different order like '-lxs' would cause
   unexpected results (as the 's' option would be skipped).
 - I've changed the headers in all files that are subject to the MozPL
   license, as they are supposed to look like when conforming.
 - Made the configure script make the config.h. The former config.h is now
   setup.h.
 - The RESOURCES and TODO files have been added to the archive.

 Angus Mackay (Nov 5, 1998)
 - Fixed getpass.c and various configure stuff

 Daniel Stenberg (Nov 3, 1998)
 - Use -H/--header for custom HTTP-headers. Lets you pass on your own
   specified headers to the remote server. I wouldn't recommend trying to use
   a header with a defined usage according to standards. Use this flag once
   for every custom header you want to add.
 - Use -B/--ftp-ascii to force ftp to use ASCII mode when transfering files.
 - Corrected the 'getlinks.pl' script, I accidentally left my silly proxy
   usage in there! Since the introduction of the .curlrc file, it is easier to
   write scripts that use curl since proxies and stuff should be in the
   .curlrc file anyway.
 - Introducing the new -F flag for HTTP POST. It supports multipart/form-data
   which means it is gonna be possible to upload files etc through HTTP POST.
   Shiraz Kanga asked for the feature and my brother,
   Björn Stenberg helped me design the user
   interface for this beast.  This feature requires quite some docs,
   since it has turned out not only quite capable, but also complicated! :-)
 - A note here, since I've received mail about it. SSLeay versions prior to
   0.8 will *not* work with curl!
 - Wil Langford reported a bug that occurred since curl
   did not properly use CRLF when issuing ftp commands. I fixed it.
 - Rearranged the order config files are read. .curlrc is now *always* read
   first and before the command line flags. -K config files then act as
   additional config items.
 - Use -q AS THE FIRST OPTION specified to prevent .curlrc from being read.
 - You can now disable a proxy by using -x "". Useful if the .curlrc file
   specifies a proxy and you wanna fetch something without going through
   that.
 - I'm thinking of dropping the -p support. Its really not useful since ports
   could (and should?) be specified as :<port> appended on the host name
   instead, both in URLs and to proxy host names.
 - Martin Staael reports curl -L bugs under Windows NT
   (test with URL http://come.to/scsde). This bug is not present in this
   version anymore.
 - Added support for the weird FTP URL type= thing. You can download a file
   using ASCII transfer by appending ";type=A" to the right of it. Other
   available types are type=D for dir-list (NLST) and type=I for binary
   transfer. I can't say I've ever seen anyone use this kind of URL though!
   :-)
 - Troy Engel pointed out a bug in my getenv("HOME")
   usage for win32 systems. I introduce getenv.c to better cope with
   this. Mr Engel helps me with the details around that...
 - A little note to myself and others, I should make the win32-binary built
   with SSL support...
 - Ryan Nelson sent me comments about building curl
   with SSL under FreeBSD. See the Makefile for details. Using the configure
   script, it should work better and automatically now...
 - Cleaned up in the port number mess in the source. No longer stores and uses
   proxy port number separate from normal port number.
 - 'configure' script working. Confirmed compiles on:
    Host         SSL  Compiler
    SunOS 5.5    no   gcc
    SunOS 5.5.1  yes  gcc
    SunOS 5.6    no   cc  (with gcc, it has the "gcc include files" problem)
    SunOS 4.1.3  no   gcc (without ANSI C headers)
    SunOS 4.1.2  no   gcc (native compiler failed)
    Linux 2.0.18 no   gcc
    Linux 2.0.32 yes  gcc
    Linux 2.0.35 no   gcc (with glibc)
    IRIX 6.2     no   gcc (cc compiles generate a few warnings)
    IRIX 6.4     no   cc  (generated warnings though)
    Win32        no   Borland
    OSF4.0	 no   ?

 - Ooops. The 5beta (and 4.10) under win32 failed if the HOME variable wasn't
   set.
 - When using a proxy, curl now guesses and uses the protocol part in cases
   like:
	curl -x proxy:80 www.site.com
   Proxies normally go nuts unless http:// is prepended to the host name, so
   if curl is used like this, it guesses protocol and appends the protocol
   string before passing it to the proxy. It already did this when used
   without proxy.
 - Better port usage with SSL through proxy now. If you specified a different
   https-port when accessing through a proxy, it didn't use that number
   correctly. I also rewrote the code that parses the stuff read from the
   proxy when you wanna connect through it with SSL.
 - Bjorn Reese helped me work around one of the compiler
   warnings on IRIX native cc compiles.

Version 4.10 (Oct 26, 1998)
 Daniel Stenberg
 - John A. Bristor suggested a config file switch,
   and since I've been having that idea kind of in the background for a long
   time I rewrote the parameter parsing function a little and now I introduce
   the -K/--config flag. I also made curl *always* (unless -K is used) try to
   load the .curlrc file for command line parameters. The syntax for the
   config file is the standard command line argument style. Details in 'curl
   -h' or the README.
 - I removed the -k option. Keep-alive isn't really anything anyone would
   want to enable with curl anyway.
 - Martin Staael helped me add the 'irix' target. Now
   "make irix" should build curl successfully on non-gcc SGI machines.
 - Single switches now toggle behaviours. I.e if you use -v -v the second
   will switch off the verbose mode the first one enabled. This is so that
   you can disable a default setting a .curlrc file enables etc.

Version 4.9 (Oct 7, 1998)
 Daniel Stenberg
 - Martin Staael suggested curl would support cookies.
   I added -b/--cookie to enable free-text cookie data to be passed. There's
   also a little blurb about general cookie stuff in the README/help text.
 - dmh <dmh at jet.es> suggested HTTP resume capabilities. Although you could
   manually get curl to resume HTTP documents, I made the -c resume flag work
   for HTTP too (unless -r is used too, which would be very odd anyway).
 - Added checklinks.pl to the archive. It is a still experimental perl script
   that checks all links of a web page by using curl.
 - Rearranged the archive hierarchy a little. Build the executable in the
   src/ dir from now on!
 - Version 4.9 and hereafter, is no longer released under the GPL license.
   I have now updated the LEGAL file etc and now this is released using the
   Mozilla Public License to avoid the plague known as "the GPL virus". You
   must make the source available if you decide to change and/or redistribute
   curl, but if you decide to use curl within something else you do not need
   to offer the world the source to that too.
 - Curl did not like HTTP servers that sent no headers at all on a GET
   request.  It is a violation of RFC2068 but appearantly some servers do
   that anyway.  Thanks to Gordon Beaton for the report!
 - -L/--location was added after a suggestion from Martin Staael. This makes
   curl ATTEMPT to follow the Location: redirect if one is present in the HTTP
   headers. If -i or -I is used with this flag, you will see headers from all
   sites the Location: points to. Do note that the first server can point to a
   second that points to a third etc. It seems the Location: parameter (said
   to be an AbsoluteURI in RFC2068) isn't always absolute.. :-/ Anyway, I've
   made curl ATTEMPT to do the best it can to deal with the reality.
 - Added getlinks.pl to the archive. getlinks.pl selectively downloads
   files that a web page links to.

Version 4.8.4
 Daniel Stenberg
 - As Julian Romero Nieto reported, curl reported wrong version number.
 - As Teemu Yli-Elsila pointed out, the win32 version of 4.8 (and probably all
   other versions for win32) didn't work with binary files since I'm too used
   to the Unix style fopen() where binary and text don't differ...
 - Ralph Beckmann brought me some changes that lets curl compile error and
   warning free with -Wall -pedantic with g++. I also took the opportunity to
   clean off some unused variables and similar.
 - Ralph Beckmann made me aware of a really odd bug now corrected. When curl
   read a set of headers from a HTTP server, divided into more than one read
   and the first read showed a full line *exactly* (i.e ending with a
   newline), curl did not behave well.

Version 4.8.3
 Daniel Stenberg
 - I was too quick to release 4.8.2 with too little testing. One of the
   changes is now reverted slightly to the 4.8.1 way since 4.8.2 couldn't
   upload files. I still think both problems corrected in 4.8.2 remain
   corrected.  Reported by Julian Romero Nieto.

Version 4.8.2
 Daniel Stenberg
 - Bernhard Iselborn reported two FTP protocol errors curl did. They're now
   corrected. Both appeared when getting files from a MS FTP server! :-)

Version 4.8.1
 Daniel Stenberg
 - Added a last update of the progress meter when the transfer is done. The
   final output on the screen didn't have to be the final size transfered
   which made it sometimes look odd.
 - Thanks to David Long I got rid of a silly bug that happened if a HTTP-page
   had nothing but header. Appearantly Solaris deals with negative sizes in
   fwrite() calls a lot better than Linux does... =B-]

Version 4.8 (Aug 31, 1998)
 Daniel Stenberg
 - Continue FTP file transfer. -c is the switch. Note that you need to
   specify a file name if you wanna resume a download (you can't resume a
   download sent to stdout). Resuming upload may be limited by the server
   since curl is then using the non-RFC959 command SIZE to get the size of
   the target file before upload begins (to figure out which offset to
   use). Use -C to specify the offset yourself! -C is handy if you're doing
   the output to something else but a plain file or when you just want to get
   the end of a file.
 - recursiveftpget.pl now features a maximum recursive level argument.

Version 4.7
 Daniel Stenberg
 - Added support to abort a download if the speed is below a certain amount
   (speed-limit) bytes per second for a certain (speed-time) time.
 - Wrote a perl script 'recursiveftpget.pl' to recursively use curl to get a
   whole ftp directory tree. It is meant as an example of how curl can be
   used.  I agree it isn't the wisest thing to do to make a separate new
   connection for each file and directory for this.

Version 4.6
 Daniel Stenberg
 - Added a first attempt to optionally parse the .netrc file for login user
   and password. If used with http, it enables user authentication. -n is
   the new switch.
 - Removed the extra newlines on the default user-agent string.
 - Corrected the missing ftp upload error messages when it failed without the
   verbose flag set. Gary W. Swearingen found it.
 - Now using alarm() to enable second-precision timeout even on the name
   resolving/connecting phase. The timeout is although reset after that first
   sequence. (This should be corrected.) Gary W. Swearingen reported.
 - Now spells "Unknown" properly, as in "Unknown option 'z'"... :-)
 - Added bug report email address in the README.
 - Added a "current speed" field to the progress meter. It shows the average
   speed the last 5 seconds. The other speed field shows the average speed of
   the entire transfer so far.

Version 4.5.1
 Linas Vepstas
 - SSL through proxy fix
 - Added -A to allow User-Agent: changes

 Daniel Stenberg
 - Made the -A work when SSL-through-proxy.

Version 4.5
 Linas Vepstas
 - More SSL corrections
 - I've added a port to AIX.
 - running SSL through a proxy causes a chunk of code to be executred twice.
   one of those blocks needs to be deleted.

 Daniel Stenberg
 - Made -i and -I work again

Version 4.4
 Linas Vepstas
 - -x can now also specify proxyport when used as in 'proxyhost:proxyport'
 - SSL fixes

Version 4.3
 Daniel Stenberg
 - Adjusted to compile under win32 (VisualC++ 5). The -P switch does not
   support network interface names in win32. I couldn't figure out how!

Version 4.2
 Linas Vepstas / Sampo Kellomaki
 - Added SSL / SSLeay support (https://)
 - Added the -T usage for HTTP POST.

 Daniel Stenberg
 - Bugfixed the SSL implementation.
 - Made -P a lot better to use other IP addresses. It now accepts a following
   parameter that can be either
        interface - i.e "eth0" to specify which interface's IP address you
                    want to use
        IP address - i.e "192.168.10.1" to specify exact IP number
        host name - i.e "my.host.domain" to specify machine
        "-"       - (any single-letter string) to make it pick the machine's
                    default
 - The Makefile is now ready to compile for solaris, sunos4 and linux right
   out of the box.
 - Better generated version string seen with 'curl -V'

Version 4.1
 Daniel Stenberg
 - The IP number returned by the ftp server as a reply to PASV does no longer
   have to DNS resolve. In fact, no IP-number-only addresses have to anymore.
 - Binds better to available port when -P is used.
 - Now LISTs ./ instead of / when used as in ftp://ftp.funet.fi/. The reason
   for this is that exactly that site, ftp.funet.fi, does not allow LIST /
   while LIST ./ is fine. Any objections?

Version 4 (1998-03-20)
 Daniel Stenberg
 - I took another huge step and changed both version number and project name!
   The reason for the new name is that there are just one too many programs
   named urlget already and this program already can a lot more than merely
   getting URLs, and the reason for the version number is that I did add the
   pretty big change in -P and since I changed name I wanted to start with
   something fresh!
 - The --style flags are working better now.
 - Listing directories with FTP often reported that the file transfer was
   incomplete. Wrong assumptions were too common for directories, why no
   size will be attempted to get compared on them from now on.
 - Implemented the -P flag that let's the ftp control issue a PORT command
   instead of the standard PASV.
 - -a for appending FTP uploads works.

***************************************************************************

Version 3.12 (14 March 1998)
 Daniel Stenberg
 - End-of-header tracking still lacked support for \r\n or just \n at the
   end of the last header line.
 Sergio Barresi
 - Added PROXY authentication.
 Rafael Sagula
 - Fixed some little bugs.

Version 3.11
 Daniel Stenberg
 - The header parsing was still not correct since the 3.2 modification...

Version 3.10
 Daniel Stenberg
 - 3.7 and 3.9 were simultaneously developed and merged into this version.
 - FTP upload did not work correctly since 3.2.

Version 3.9
 Rafael Sagula
 - Added the "-e <url> / --referer <url>" option where we can specify
   the referer page. Obviously, this is necessary only to fool the
   server, but...

Version 3.7
 Daniel Stenberg
 - Now checks the last error code sent from the ftp server after a file has
   been received or uploaded. Wasn't done previously.
 - When 'urlget <host>' is used without a 'protocol://' first in the host part,
   it now checks for host names starting with ftp or gopher and if it does,
   it uses that protocol by default instead of http.

Version 3.6
 Daniel Stenberg
 - Silly mistake made the POST bug. This has now also been tested to work with
   proxy.

Version 3.5
 Daniel Stenberg
 - Highly inspired by Rafael Sagula's changes to the 3.1 that added an almost
   functional POST, I applied his changes into this version and made them work.
   (It seems POST requires the Content-Type and Content-Length headers.) It is
   now usable with the -d switch.

Version 3.3 - 3.4
 Passed to avoid confusions

Version 3.2
 Daniel Stenberg
 - Major rewrite of two crucial parts of this code: upload and download.
   They are both now using a select() switch, that allows much better
   progress meter and time control.
 - alarm() usage removed completely
 - FTP get can now list directory contents if the path ends with a slash '/'.
   Urlget on a ftp-path that doesn't end with a slash means urlget will
   attempt getting it as a file name.
 - FTP directory view supports -l for "list-only" which lists the file names
   only.
 - All operations support -m for max time usage in seconds allowed.
 - FTP upload now allows the size of the uploaded file to be provided, and
   thus it can better check it actually uploaded the whole file. It also
   makes the progress meter for uploads much better!
 - Made the parameter parsing fail in cases like 'urlget -r 900' which
   previously tried to connect to the host named '900'.

Version 3.1
 Kjell Ericson
 - Pointed out how to correct the 3 warnings in win32-compiles.

 Daniel Stenberg
 - Removed all calls to exit().
 - Made the short help text get written to stdout instead of stderr.
 - Made this file instead of keeping these comments in the source.
 - Made two callback hooks, that enable external programs to use urlget()
   easier and to grab the output/offer the input easier.
 - It is evident that Win32-compiles are painful. I watched the output from
   the Borland C++ v5 and it was awful. Just ignore all those warnings.

Version 3.0
 Daniel Stenberg
 - Added FTP upload capabilities. The name urlget gets a bit silly now
   when we can put too... =)
 - Restructured the source quite a lot.
   Changed the urlget() interface. This way, we will survive changes much
   better. New features can come and old can be removed without us needing
   to change the interface. I've written a small explanation in urlget.h
   that explains it.
 - New flags include -t, -T, -O and -h. The -h text is generated by the new
   mkhelp script.

Version 2.9
 Remco van Hooff
 - Added a fix to make it compile smoothly on Amiga using the SAS/C
   compiler.

 Daniel Stenberg
 - Believe it or not, but the STUPID Novell web server seems to require
   that the Host: keyword is used, so well I use it and I (re-introduce) the
   urlget User-Agent:. I still have to check that this Host: usage works with
   proxies... 'Host:' is required for HTTP/1.1 GET according to RFC2068.

Version 2.8
 Rafael Sagula
 - some little modifications

Version 2.7
 Daniel Stenberg
 - Removed the -l option and introduced the -f option instead. Now I'll
   rewrite the former -l kludge in an external script that'll use urlget to
   fetch multipart files like that.
 - '-f' is introduced, it means Fail without output in case of HTTP server
   errors (return code >=400).
 - Added support for -r, ranges. Specify which part of a document you
   want, and only that part is returned. Only with HTTP/1.1-servers.
 - Split up the source in 3 parts. Now all pure URL functions are in
   urlget.c and stuff that deals with the stand-alone program is in main.c.
 - I took a few minutes and wrote an embryo of a README file to explain
   a few things.

Version 2.6
 Daniel Stenberg
 - Made the -l (loop) thing use the new CONF_FAILONERROR which makes
   urlget() return error code if non-successful. It also won't output anything
   then. Now finally removed the HTTP 1.0 and error 404 dependencies.
 - Added -I which uses the HEAD request to get the header only from a
   http-server.

Version 2.5
 Rafael Sagula
 - Made the progress meter use HHH:MM:SS instead of only seconds.

Version 2.4
 Daniel Stenberg
 - Added progress meter. It appears when downloading > BUFFER SIZE and
   mute is not selected. I found out that when downloading large files from
   really really slow sites, it is desirable to know the status of the
   download. Do note that some downloads are done unawaring of the size, which
   makes the progress meter less thrilling ;) If the output is sent to a tty,
   the progress meter is shut off.
 - Increased buffer size used for reading.
 - Added length checks in the user+passwd parsing.
 - Made it grok user+passwd for HTTP fetches. The trick is to base64
   encode the user+passwd and send an extra header line. Read chapter 11.1 in
   RFC2068 for details. I added it to be used just like the ftp one.  To get a
   http document from a place that requires user and password, use an URL
   like:

        http://user:passwd@www.site.to.leach/doc.html

   I also added the -u flag, since WHEN USING A PROXY YOU CAN'T SPECIFY THE
   USER AND PASSWORD WITH HTTP LIKE THAT. The -u flag works for ftp too, but
   not if used with proxy. To do the same as the above one, you can invoke:

        urlget -u user:passwd http://www.site.to.leach/doc.html

Version 2.3
 Rafael Sagula
 - Added "-o" option (output file)
 - Added URG_HTTP_NOT_FOUND return code.
   (Daniel's note:)
   Perhaps we should detect all kinds of errors and instead of writing that
   custom string for the particular 404-error, use the error text we actually
   get from the server. See further details in RFC2068 (HTTP 1.1
   definition). The current way also relies on a HTTP/1.0 reply, which newer
   servers might not do.
 - Looping mode ("-l" option). It's easier to get various split files.
   (Daniel's note:)
   Use it like 'urlget -l 1 http://from.this.site/file%d.html', which will
   make urlget to attempt to fetch all files named file1.html, file2.html etc
   until no more files are found. This is only a modification of the
   STAND_ALONE part, nothing in the urlget() function was modfified for this.
 Daniel Stenberg
 - Changed the -h to be -i instead. -h should be preserved to help use.
 - Bjorn Reese indicated that Borland _might_ use '_WIN32' instead of the
   VC++ WIN32 define and therefore I added a little fix for that.

Version 2.2
 Johan Andersson
 - The urlget function didn't set the path to url when using proxy.
 - Fixed bug with IMC proxy. Now using (almost) complete GET command.

 Daniel Stenberg
 - Made it compile on Solaris. Had to reorganize the includes a bit.
   (so Win32, Linux, SunOS 4 and Solaris 2 compile fine.)
 - Made Johan's keepalive keyword optional with the -k flag (since it
   makes a lot of urlgets take a lot longer time).
 - Made a '-h' switch in case you want the HTTP-header in the output.

Version 2.1
 Daniel Stenberg and Kjell Ericson
 - Win32-compilable
 - No more global variables
 - Mute option (no output at all to stderr)
 - Full range of return codes from urlget(), which is now written to be a
   function for easy-to-use in [other] programs.
 - Define STAND_ALONE to compile the stand alone urlget program
 - Now compiles with gcc options -ansi -Wall -pedantic ;)

Version 2.0
 - Introducing ftp GET support. The FTP URL type is recognized and used.
 - Renamed the project to 'urlget'.
 - Supports the user+passwd in the FTP URL (otherwise it tries anonymous
   login with a weird email address as password).

Version 1.5
 Daniel Stenberg
 - The skip_header() crap messed it up big-time. By simply removing that
   one we can all of a sudden download anything ;)
 - No longer requires a trailing slash on the URLs.
 - If the given URL isn't prefixed with 'http://', HTTP is assumed and
   given a try!
 - 'void main()' is history.

Version 1.4
 Daniel Stenberg
 - The gopher source used the ppath variable instead of path which could
   lead to disaster.

Version 1.3
 Daniel Stenberg
 - Well, I added a lame text about the time it took to get the data. I also
   fought against Johan to prevent his -f option (to specify a file name
   that should be written instead of stdout)! =)
 - Made it write 'connection refused' for that particular connect()
   problem.
 - Renumbered the version. Let's not make silly 1.0.X versions, this is
   a plain 1.3 instead.

Version 1.2
 Johan Andersson
 - Discovered and fixed the problem with getting binary files. puts() is
   now replaced with fwrite(). (Daniel's note: this also fixed the buffer
   overwrite problem I found in the previous version.)

 Rafael Sagula
 - Let "-p" before "-x".

 Daniel Stenberg
 - Bugfixed the proxy usage. It should *NOT* use nor strip the port number
   from the URL but simply pass that information to the proxy. This also
   made the user/password fields possible to use in proxy [ftp-] URLs.
   (like in ftp://user:password@ftp.my.site:8021/README)

 Johan Andersson
 - Implemented HTTP proxy support.
 - Receive byte counter added.

 Bjorn Reese
 - Implemented URLs (and skipped the old syntax).
 - Output is written to stdout, so to achieve the above example, do:
   httpget http://143.54.10.6/info_logo.gif > test.gif

Version 1.1
 Daniel Stenberg
 - Adjusted it slightly to accept named hosts on the command line. We
   wouldn't wanna use IP numbers for the rest of our lifes, would we?

Version 1.0
  Rafael Sagula
  - Wrote the initial httpget, which started all this!
