Merged _all_ old changelogs into the single CHANGES.0 file. Having a new one

for every year is giving us too many files! I also split out the changes
from 2006 from CHANGES to CHANGES.0 now.

   our attention by Nathanael Nerode who filed debian bug report #405226
   (http://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
-  (http://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
-  (http://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
-  (http://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.
-  (http://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
-  (http://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 (http://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 (http://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
-  (http://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 (http://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.
-  http://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.
-  http://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: <http://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
-  (http://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
-  (http://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 (http://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 (http://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"
-  (http://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 (http://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
-  (http://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 (http://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.
