From 6f7d0a7cbd0578dc20a22279269a14a143d7e8ee Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Wed, 2 May 2007 13:14:56 +0000 Subject: 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. --- CHANGES.2005 | 1183 ---------------------------------------------------------- 1 file changed, 1183 deletions(-) delete mode 100644 CHANGES.2005 (limited to 'CHANGES.2005') diff --git a/CHANGES.2005 b/CHANGES.2005 deleted file mode 100644 index 57f0dbca6..000000000 --- a/CHANGES.2005 +++ /dev/null @@ -1,1183 +0,0 @@ -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: http://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. http://curl.haxx.se/bug/view.cgi?id=1356715 - -- Jan Kunder's debian bug report - http://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: - http://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: http://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! (http://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 - (http://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 - (http://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 (http://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 (http://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. http://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 - http://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)." - http://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 http://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 (http://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: - http://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: - http://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: - http://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. http://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. - - Sponsored by CU*Answers - -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 - (http://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 - (http://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 - (http://curl.haxx.se/bug/view.cgi?id=1216500). Comment in - http://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': - http://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: http://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. http://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 - (http://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 - (http://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 - http://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: - http://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: - http://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: - http://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: - http://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. -- cgit v1.2.3
