_ _ ____ _ ___| | | | _ \| | / __| | | | |_) | | | (__| |_| | _ <| |___ \___|\___/|_| \_\_____| Changelog Kamil Dudka (30 Jun 2010) - http_ntlm: add support for NSS When configured with '--without-ssl --with-nss', NTLM authentication now uses NSS crypto library for MD5 and DES. For MD4 we have a local implementation in that case. More details are available at https://bugzilla.redhat.com/603783 In order to get it working, curl_global_init() must be called with CURL_GLOBAL_SSL or CURL_GLOBAL_ALL. That's necessary because NSS needs to be initialized globally and we do so only when the NSS library is actually required by protocol. The mentioned call of curl_global_init() is responsible for creating of the initialization mutex. There was also slightly changed the NSS initialization scenario, in particular, loading of the NSS PEM module. It used to be loaded always right after the NSS library was initialized. Now the library is initialized as soon as any SSL or NTLM is required, while the PEM module is prevented from being loaded until the SSL is actually required. Kamil Dudka (4 Apr 2010) - Eliminated a race condition in Curl_resolv_timeout(). Daniel Stenberg (22 Mar 2010) - Thomas Lopatic fixed the alarm()-based DNS timeout: Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in case of a timeout, the signal handler for SIGALRM never gets removed. I think that in my case it gets executed at some point later on when execution has long left Curl_resolv_timeout() or even the cURL library. The code that is jumped to with siglongjmp() simply sets the error message to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess that instead of simply returning without cleaning up, the code should have a goto that jumps to the spot right after the call to Curl_resolv(). Kamil Dudka (19 Mar 2010) - Improved Curl_read() to not ignore the error returned from Curl_ssl_recv(). Daniel Stenberg (17 Dec 2009) - Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I was a bit too quick and broke test case 1101 with that change. The order of some of the setups is sensitive. I now changed it slightly again to make sure we do them in this order: 1 - parse URL and figure out what protocol is used in the URL 2 - prepend protocol:// to URL if missing 3 - parse name+password off URL, which needs to know what protocol is used (since only some allows for name+password in the URL) 4 - figure out if a proxy should be used set by an option 5 - if no proxy option, check proxy environment variables 6 - run the protocol-specific setup function, which needs to have the proxy already set Daniel Stenberg (15 Dec 2009) - Jon Nelson found a regression that turned out to be a flaw in how libcurl detects and uses proxies based on the environment variables. If the proxy was given as an explicit option it worked, but due to the setup order mistake proxies would not be used fine for a few protocols when picked up from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added test case 1106 that verifies this functionality. (http://curl.haxx.se/bug/view.cgi?id=2913886) Kamil Dudka (12 Nov 2009) - Kevin Baughman provided a fix preventing libcurl-NSS from crash on doubly closed NSPR descriptor. The issue was hard to find, reported several times before and always closed unresolved. More info at the RH bug: https://bugzilla.redhat.com/534176 - libcurl-NSS now tries to reconnect with TLS disabled in case it detects a broken TLS server. However it does not happen if SSL version is selected manually. The approach was originally taken from PSM. Kaspar Brand helped me to complete the patch. Original bug reports: https://bugzilla.redhat.com/525496 https://bugzilla.redhat.com/527771 Version 7.19.7 (4 November 2009) Daniel Stenberg (2 Nov 2009) - As reported independent by both Stan van de Burgt and Didier Brisebourg, CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when getting data from ldap! Daniel Stenberg (31 Oct 2009) - Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the download was 0 bytes, as libcurl would then return the size as unknown (-1) and not 0. I wrote a fix and test case 566 to verify it. Daniel Stenberg (30 Oct 2009) - Liza Alenchery mentioned a problem with re-used SCP connection when a bad auth is used, as it caused a crash. I failed to repeat the issue, but still made a change that now forces the TCP connection used for a freed SCP session to get closed and not be re-used. - "Tom" posted a bug report that mentioned how libcurl did wrong when doing a POST using a read callback, with Digest authentication and "Transfer-Encoding: chunked" enforced. I would then cause the first request to be wrongly sent and then basically hang until the server closed the connection. I fixed the problem and added test case 565 to verify it. Daniel Stenberg (25 Oct 2009) - Dima Barsky made the curl cookie parser accept cookies even with blank or unparsable expiry dates and then treat them as session cookies - previously libcurl would reject cookies with a date format it couldn't parse. Research shows that the major browser treat such cookies as session cookies. I modified test 8 and 31 to verify this. Daniel Stenberg (21 Oct 2009) - Attempt to use pkg-config for finding out libssh2 installation details during configure. - A patch in bug report #2883177 (http://curl.haxx.se/bug/view.cgi?id=2883177) by Johan van Selst introduced the --crlfile option to curl, which makes curl tell libcurl about a file with CRL (certificate revocation list) data to read. Daniel Stenberg (18 Oct 2009) - Ray Dassen provided a patch in Debian's bug tracker (bug number #551461) that now makes curl_getdate(3) actually handles RFC 822 formatted dates that use the "single letter military timezones". http://www.rfc-ref.org/RFC-TEXTS/822/chapter5.html has the details. - Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts data! - John Dennis filed bug report #2873666 (http://curl.haxx.se/bug/view.cgi?id=2873666) which identified a problem which made libcurl loop infinitely when given incorrect credentials when using HTTP GSS negotiate authentication. He also provided a small and simple patch for it. - Kevin Baughman found a double close() problem with libcurl-NSS, as when libcurl called NSS to close the SSL "session" it also closed the actual socket. Yang Tse (17 Oct 2009) - Bug report #2866724 indicated (http://curl.haxx.se/bug/view.cgi?id=2866724) that curl on Windows failed when writing files whose file names originally contained characters which are not valid for file names on Windows. Dan Fandrich provided an initial patch and another revised one to fix this issue. Daniel Stenberg (1 Oct 2009) - Tom Mueller correctly reported in bug report #2870221 (http://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an incorrect return code from the internal trynextip() function which caused him grief. This is a regression that was introduced in 7.19.1 and I find it strange it hasn't hit us harder, but I won't persue into figuring out exactly why. - Constantine Sapuntzakis: The current implementation will always set SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger. The patch doesn't do a setsockopt if SO_SNDBUF is already greater than CURL_WRITE_SIZE. This should help folks who have set up their computer with large send buffers. Daniel Stenberg (27 Sep 2009) - I introduced a maximum limit for received HTTP headers. It is controlled by the define CURL_MAX_HTTP_HEADER which is even exposed in the public header file to allow for users to fairly easy rebuild libcurl with a modified limit. The rationale for a fixed limit is that libcurl is realloc()ing a buffer to be able to put a full header into it, so that it can call the header callback with the entire header, but that also risk getting it into trouble if a server by mistake or willingly sends a header that is more or less without an end. The limit is set to 100K. Daniel Stenberg (26 Sep 2009) - John P. McCaskey posted a bug report that showed how libcurl did wrong when saving received cookies with no given path, if the path in the request had a query part. That is means a question mark (?) and characters on the right side of that. I wrote test case 1105 and fixed this problem. Kamil Dudka (26 Sep 2009) - Implemented a protocol independent way to specify blocking direction, used by transfer.c for blocking. It is currently used only by SCP and SFTP protocols. This enhancement resolves an issue with 100% CPU usage during SFTP upload, reported by Vourhey. Daniel Stenberg (25 Sep 2009) - Chris Mumford filed bug report #2861587 (http://curl.haxx.se/bug/view.cgi?id=2861587) identifying that libcurl used the OpenSSL function X509_load_crl_file() wrongly and failed if it would load a CRL file with more than one certificate within. This is now fixed. Daniel Stenberg (16 Sep 2009) - Sven Anders reported that we introduced a cert verfication flaw for OpenSSL- powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name field in the certficate it had to match and so even if non-DNS and non-IP entry was present it caused the verification to fail. Daniel Fandrich (15 Sep 2009) - Moved the libssh2 checks after the SSL library checks. This helps when statically linking since libssh2 needs the SSL library link flags to be set up already to satisfy its dependencies. This wouldn't be necessary if the libssh2 configure check was changed to use pkg-config since the --static flag would add the dependencies automatically. Yang Tse (14 Sep 2009) - Revert Joshua Kwan's patch committed 11 Sep 2009. Some systems poll function sets POLLHUP in revents without setting POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some libcurl code execution paths this could trigger busy wait loops with high CPU usage until a timeout condition aborted the loop. The reverted patch addressed the above issue for a very specific case, when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now superceeds this one. Guenter Knauf (11 Sep 2009) - Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares. This fixes a loop problem with high CPU usage. Daniel Stenberg (10 Sep 2009) - Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0 which internally then is treated as a session cookie. That particular date is now made to get the value of 1. Daniel Stenberg (2 Sep 2009) - Daniel Johnson found a flaw in the code converting sftp-errors to libcurl errors. Daniel Stenberg (1 Sep 2009) - Peter Sylvester made a debug feature for Curl_resolv() that now will force libcurl to resolve 'localhost' whatever name you use in the URL *if* you set the --interface option to (exactly) "LocalHost". This will enable us to write tests for custom hosts names but still use a local host server. - configure now tries to use pkg-config for a number of sub-dependencies even when cross-compiling. The key to success is then you properly setup PKG_CONFIG_PATH before invoking configure. I also improved how NSS is detected by trying nss-config if pkg-config isn't present, and as a last resort just use the lib name and force the user to setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would add a range of various libs that would almost never be quite correct. Daniel Stenberg (31 Aug 2009) - When using the multi interface with FTP and you asked for NOBODY, you did no QUOTE commands and the request used the same path as the connection had already changed to, it would decide that no commands would be necessary for the "DO" action and that was not handled properly but libcurl would instead hang. Kamil Dudka (28 Aug 2009) - Improved error message for not matching certificate subject name in libcurl-NSS. Originally reported at: https://bugzilla.redhat.com/show_bug.cgi?id=516056#c9 Patrick Monnerat (24 Aug 2009) - Introduced a SYST-based test to properly set-up name format when dealing with the OS/400 FTP server. - Fixed an ftp_readresp() bug preventing detection of failing control socket and causing FTP client to loop forever. Daniel Stenberg (24 Aug 2009) - Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work properly and provided a fix. http://curl.haxx.se/bug/view.cgi?id=2843008 - Eric Wong introduced support for the new option -T. (dot) that makes curl read stdin in a non-blocking fashion. This also brings back -T- (minus) to the previous blocking behavior since it could break stuff for people at times. Michal Marek (21 Aug 2009) - With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like ftp://example.com;type=i if the user specified ftp://example.com without the slash. Daniel Stenberg (21 Aug 2009) - Andre Guibert de Bruet pointed out a missing return code check for a strdup() that could lead to segfault if it returned NULL. I extended his suggest patch to now have Curl_retry_request() return a regular return code and better check that. - Lots of good work by Krister Johansen, mostly related to pipelining: Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks Fix data corruption issue with re-connected transfers Fix use after free if we're completed but easy_conn not NULL Kamil Dudka (13 Aug 2009) - Changed NSS code to not ignore the value of ssl.verifyhost and produce more verbose error messages. Originally reported at: https://bugzilla.redhat.com/show_bug.cgi?id=516056 Daniel Stenberg (12 Aug 2009) - Karl Moerder fixed the Makefile.vc* makefiles to include the new file nonblock.c so that they work fine again - I expanded test 517 with a bunch of more dates that originate from the Chrome browser test suite. It turns out most of them get parsed the same way. Version 7.19.6 (12 August 2009) Daniel Stenberg (12 Aug 2009) - Carsten Lange reported a bug and provided a patch for TFTP upload and the sending of the TSIZE option. I don't like fixing bugs just hours before a release, but since it was broken and the patch fixes this for him I decided to get it in anyway. Daniel Stenberg (11 Aug 2009) - Peter Sylvester made the HTTPS test server use specific certificates for each test, so that the test suite can now be used to actually test the verification of cert names etc. This made an error show up in the OpenSSL- specific code where it would attempt to match the CN field even if a subjectAltName exists that doesn't match. This is now fixed and verified in test 311. - Benbuck Nason posted the bug report #2835196 (http://curl.haxx.se/bug/view.cgi?id=2835196), fixing a few compiler warnings when mixing ints and bools. Daniel Fandrich (10 Aug 2009) - Fixed a memory leak in the FTP code and an off-by-one heap buffer overflow. Daniel Fandrich (9 Aug 2009) - Fixed some memory leaks in the command-line tool that caused most of the torture tests to fail. Daniel Stenberg (2 Aug 2009) - Curt Bogmine reported a problem with SNI enabled on a particular server. We should introduce an option to disable SNI, but as we're in feature freeze now I've addressed the obvious bug here (pointed out by Peter Sylvester): we shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected. Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular option for SNI, or are we simply not using it? Daniel Stenberg (1 Aug 2009) - Scott Cantor posted the bug report #2829955 (http://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert verification flaw found and exploited by Moxie Marlinspike. The presentation he did at Black Hat is available here: https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike Apparently at least one CA allowed a subjectAltName or CN that contain a zero byte, and thus clients that assumed they would never have zero bytes were exploited to OK a certificate that didn't actually match the site. Like if the name in the cert was "example.com\0theatualsite.com", libcurl would happily verify that cert for example.com. libcurl now better uses the length of the extracted name, not using the zero termination for getting the string length. This fixing only made and needed in OpenSSL interfacing code. - Tanguy Fautre pointed out that OpenSSL's function RAND_screen() (present only in some OpenSSL installs - like on Windows) isn't thread-safe and we agreed that moving it to the global_init() function is a decent way to deal with this situation. - Alexander Beedie provided the patch for a noproxy problem: If I have set CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually could still end up using a proxy if a proxy environment variable was set. Daniel Stenberg (27 Jul 2009) - All the quote options (CURLOPT_QUOTE, CURLOPT_POSTQUOTE and CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to send when using FTP, as a sign that libcurl shall simply ignore the response from the server instead of treating it as an error. Not treating a 400+ FTP response code as an error means that failed commands will not abort the chain of commands, nor will they cause the connection to get disconnected. Daniel Stenberg (26 Jul 2009) - Johan van Selst posted bug report #2825989 (http://curl.haxx.se/bug/view.cgi?id=2825989) pointing out that OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm, and provided the solution too: to use OpenSSL_add_all_algorithms() in addition to the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in OpenSSL 0.9.5 Daniel Stenberg (23 Jul 2009) - Added CURLOPT_SSH_KNOWNHOSTS, CURLOPT_SSH_KEYFUNCTION, CURLOPT_SSH_KEYDATA. They introduce known_host support for SSH keys to libcurl. See docs for details. Note that this feature depends on a new enough libssh2 version, to be supported in libssh2 1.2 and later (or current git repo at this time). Michal Marek (22 Jul 2009) - David Binderman found a memory and fd leak in lib/gtls.c:load_file() (https://bugzilla.novell.com/523919). When looking at the code, I found that also the ptr pointer can leak. Kamil Dudka (20 Jul 2009) - Claes Jakobsson improved the support for client certificates handling in NSS-powered libcurl. Now the client certificates can be selected automatically by a NSS built-in hook. Additionally pre-login to all PKCS11 slots is no more performed. It used to cause problems with HW tokens. - Fixed reference counting for NSS client certificates. Now the PEM reader module should be always properly unloaded on Curl_nss_cleanup(). If the unload fails though, libcurl will try to reuse the already loaded instance. Daniel Fandrich (15 Jul 2009) - Added nonblock.c to the non-automake makefiles (note that the dependencies in the Watcom makefiles aren't quite correct). Michal Marek (15 Jul 2009) - Changed the description of CURLINFO_OS_ERRNO to make it clear that the errno is not reset on success. Guenter Knauf (14 Jul 2009) - renamed generated config.h to curl_config.h to avoid any future clashes with config.h from other projects. Daniel Stenberg (9 Jul 2009) - Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses for setting a file descriptor non-blocking. Used by the functionality Eric himself brough on June 15th. Daniel Stenberg (8 Jul 2009) - Constantine Sapuntzakis posted bug report #2813123 (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the problem: Url A is accessed using auth. Url A redirects to Url B (on a different server0. Url B reuses a persistent connection. Url B has auth, even though it's on a different server. Note: if Url B does not reuse a persistent connection, auth is not sent. reason: data->state.first_host is not initialized becuase Curl_http_connect is not called when a connection is reused. Solution: move initialization of data->state.first_host to Curl_http. No code before Curl_http uses data->state.first_host anyway. Guenter Knauf (4 Jul 2009) - Markus Koetter provided a patch to avoid getnameinfo() usage which broke a couple of both IPv4 and IPv6 autobuilds. Daniel Stenberg (29 Jun 2009) - Markus Koetter made CURLOPT_FTPPORT (and curl's -P/--ftpport) support a port range if given colon-separated after the host name/address part. Like "192.168.0.1:2000-10000" - Modified the separators used for CURLOPT_CERTINFO in multi-part outputs. I don't know how they got wrong in the first place, but using this output format makes it possible to quite easily separate the string into an array of multiple items. Daniel Fandrich (16 June 2009) - Added a few more compiler warning options for gcc. Daniel Stenberg (16 Jun 2009) - Reuven Wachtfogel made curl -o - properly produce a binary output on windows (no newline translations). Use -B/--use-ascii if you rather get the ascii approach. Michal Marek (16 Jun 2009) - When doing non-anonymous ftp via http proxies and the password is not provided in the url, add it there (squid needs this). Daniel Stenberg (15 Jun 2009) - Eric Wong's patch: This allows curl(1) to be used as a client-side tunnel for arbitrary stream protocols by abusing chunked transfer encoding in both the HTTP request and HTTP response. This requires server support for sending a response while a request is still being read, of course. If attempting to read from stdin returns EAGAIN, then we pause our sender. This leaves curl to attempt to read from the socket while reading from stdin (and thus sending) is paused. This change was needed to allow successfully tunneling the git protocol over HTTP (--no-buffer is needed, as well). Patrick Monnerat (15 Jun 2009) - Replaced use of standard C library rand()/srand() by our own pseudo-random number generator. Yang Tse (11 Jun 2009) - I adapted testcurl script to allow building test harness programs when cross-compiling for a *-*-mingw* host. Daniel Stenberg (10 Jun 2009) - Fabian Keil ran clang on the (lib)curl code, found a bunch of warnings and contributed a range of patches to fix them. Yang Tse (10 Jun 2009) - I introduced configure script option --enable-curldebug which now allows the decoupled enabling or disabling of the curl debug memory tracking feature from the --enable-debug option which no longer controls this. curl --version will list 'Debug' feature for debug enabled builds, and will list 'TrackMemory' feature for curl debug memory tracking capable builds. These features are independent and can be controlled when running the configure script. When --enable-debug is given both features will be enabled, unless some restriction prevents memory tracking from being used. Internally, definition of preprocessor symbol DEBUGBUILD restricts code which is only compiled for debug enabled builds. And symbol CURLDEBUG is used to differentiate code which is _only_ used for memory tracking. Yang Tse (9 Jun 2009) - Daniel Steinberg pointed out that Curl_FormInit() in formdata.c was not initializing the fread callback pointer and this triggered a compiler warning, also provided a friendly suggestion on how to fix it. Daniel Stenberg (8 Jun 2009) - Claes Jakobsson provided a patch for libcurl-NSS that fixed a bad refcount issue with client certs that caused issues like segfaults. http://curl.haxx.se/mail/lib-2009-05/0316.html - Triggered by bug report #2798852 and the patch in there, I fixed configure to detect gnutls build options with pkg-config only and not libgnutls-config anymore since GnuTLS has stopped distributing that tool. If an explicit path is given to configure, we will instead guess on how to link and use that lib. I did not use the patch from the bug report. Yang Tse (8 Jun 2009) - Igor Novoseltsev adjusted Makefile.vxworks to get sources and headers included from Makefile.inc, and provided docs\INSTALL VxWorks section. - I removed buildconf.bat from release and daily snapshot archives. This file is only for CVS tree checkout builds. Daniel Stenberg (8 Jun 2009) - Eric Wong fixed --no-buffer to actually switch off output buffering. Been broken since 7.19.0 Bill Hoffman (6 Jun 2009) - Added some cmake docs and fixed socklen_t in the build. Yang Tse (5 Jun 2009) - John E. Malmberg provided VMS specific patch: "This fixes an existing bug in urlglob.c where it was not converting the Curl Unix exit code to a VMS DCL compatible exit code. This fix required the enhancement described next. This also adds an enhancement to main.c so that when curl is run under a Unix shell like Bash on VMS, it will return the standard Unix exit codes and messages." And another patch for docs/examples. I introduced os-specific.c and os-specific.h for use in curl tool code and adjusted John E. Malmberg's patch placement to use these new files as an effort to prevent main.c from growing ad infinitum. Code already existing in main.c which is OS specific should be moved into these files. Daniel Stenberg (4 June 2009) - Setting the Content-Length: header from your app when you do a POST or PUT is almost always a VERY BAD IDEA. Yet there are still apps out there doing this, and now recently it triggered a bug/side-effect in libcurl as when libcurl sends a POST or PUT with NTLM, it sends an empty post first when it knows it will just get a 401/407 back. If the app then replaced the Content-Length header, it caused the server to wait for input that libcurl wouldn't send. Aaron Oneal reported this problem in bug report #2799008 (http://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix. Yang Tse (4 Jun 2009) - Igor Novoseltsev provided patches and information, that after some adjustments to better fit curl's way of doing things, have resulted in the posibility of building libcurl for VxWorks. Daniel Fandrich (2 June 2009) - Checked in a Google Android make file. To use it, you must first create a config.h file by running configure in the Android environment, which doesn't seem to be easy to do. If no easy way can be found, a static config-android.h may need to be created and checked in to the libcurl source tree. Daniel Stenberg (1 June 2009) - Claes Jakobsson fixed the configure script to better find and use NSS without pkg-config. Yang Tse (1 Jun 2009) - John E. Malmberg provided a VMS specific clean-up for curl.h, and pointed out that the configure script was failing to detect the timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due to definition taking place in socket.h instead of time.h. I have adjusted configure script to also include this header when checking struct timeval. Daniel Stenberg (27 May 2009) - Frank McGeough provided a small OpenSSL #include fix to make libcurl compile fine with Nokia 5th edition 1.0 SDK for Symbian. - Andre Guibert de Bruet found a call to a OpenSSL function that didn't check for a failure properly. - Mike Crowe pointed out that setting CURLOPT_USERPWD to NULL used to clear the auth credentials back in 7.19.0 and earlier while now you have to set "" to get the same effect. His patch brings back the ability to use NULL. - Claes Jakobsson fixed libcurl-NSS to build fine even without the PK11_CreateGenericObject() function. Daniel Stenberg (25 May 2009) - bug report #2796358 (http://curl.haxx.se/bug/view.cgi?id=2796358) pointed out that the cookie parser would leak memory when it parses cookies that are received with domain, path etc set multiple times in the same header. While such a cookie is questionable, they occur in the wild and libcurl no longer leaks memory for them. I added such a header to test case 8. Daniel Fandrich (22 May 2009) - Removed some obsolete digest code that caused a valgrind error in test 551. Daniel Fandrich (20 May 2009) - Added "non-existing host" test keywords to make it easy to skip those tests on machines that have broken DNS configurations (such as those configured to use OpenDNS). Daniel Stenberg (19 May 2009) - Kamil Dudka brought the patch from the Redhat bug entry https://bugzilla.redhat.com/show_bug.cgi?id=427966 which was libcurl closing a bad file descriptor when closing down the FTP data connection. Caolan McNamara seems to be the original author of it. Version 7.19.5 (18 May 2009) Daniel Stenberg (17 May 2009) - James Bursa posted a patch to the mailing list that fixed a problem with no_proxy which made it not skip the proxy if the URL entered contained a user name. I added test case 1101 to verify. Daniel Stenberg (11 May 2009) - Balint Szilakszi reported a memory leak when libcurl did gzip decompression of streams that had some parts (legitimately) missing. We now provide and use a proper cleanup function for the content encoding submodule. http://curl.haxx.se/mail/lib-2009-05/0092.html - Kamil Dudka provided a fix for libcurl-NSS reported by Michael Cronenworth at https://bugzilla.redhat.com/show_bug.cgi?id=453612#c12 If an incorrect password is given while loading a private key, libcurl ends up in an infinite loop consuming memory. The bug is critical. - I fixed the problem with doing NTLM, POST and then following a 302 redirect, as reported by Ebenezer Ikonne (on curl-users) and Laurent Rabret (on curl-library). The transfer was mistakenly marked to get more data to send but since it didn't actually have that, it just hung there... Daniel Stenberg (10 May 2009) - Andre Guibert de Bruet correctly pointed out an over-alloc with one wasted byte in the digest code. Yang Tse (9 May 2009) - Removed DOS and TPF package's subdirectory Makefile.am, it was only used to include some files in the distribution tarball serving no other purpose. Files from the DOS and TPF subdirectories are now included in the EXTRA_DIST of the Makefile in the parent subdirectory. Yang Tse (8 May 2009) - Changed host name literal in several tests to one under the haxx.se domain. - Renamed vc6 workspace and project files to avoid filename clash when used for conversion to later VS versions. Daniel Stenberg (8 May 2009) - Constantine Sapuntzakis fixed bug report #2784055 (http://curl.haxx.se/bug/view.cgi?id=2784055) identifying a problem to connect to SOCKS proxies when using the multi interface. It turned out to almost not work at all previously. We need to wait for the TCP connect to be properly verified before doing the SOCKS magic. There's still a flaw in the FTP code for this. Daniel Stenberg (7 May 2009) - Made the SO_SNDBUF setting for the data connection socket for ftp uploads as well. See change 28 Apr 2009. Yang Tse (7 May 2009) - Fixed an issue affecting FTP transfers, introduced with the transfer.c patch committed May 4. Daniel Stenberg (7 May 2009) - Man page *roff problems fixed thanks to input from Colin Watson. Problems reported in the Debian package. - Vijay G filed bug report #2723236 (http://curl.haxx.se/bug/view.cgi?id=2723236) identifying a problem with libcurl's TFTP code and its lack of dealing with the OACK packet. Yang Tse (5 May 2009) - Fixed the --ftp-port address of test #251 to the CLIENTIP address, and reverted the change affecting test suite harness committed 4 May. Daniel Stenberg (5 May 2009) - Inspired by Michael Smith's session id fix for OpenSSL, I did the corresponding fix in the GnuTLS code: make sure to store the new session id in case the previous re-used one is rejected. Daniel Stenberg (4 May 2009) - Michael Smith posted bug report #2786255 (http://curl.haxx.se/bug/view.cgi?id=2786255) with a patch, identifying how libcurl did not deal with SSL session ids properly if the server rejected a re-use of one. Starting now, it will forget the rejected one and remember the new. This change was for OpenSSL only, it is likely that other SSL lib code needs similar fixes. Yang Tse (4 May 2009) - Applied David McCreedy's "transfer.c fixes for CURL_DO_LINEEND_CONV and non-ASCII platform HTTP requests" patch addressing two HTTP PUT problems: 1) On non-ASCII platforms not all of the protocol portions of the PUT are being translated to ASCII. 2) On all platforms the line endings of part of the protocol portions are mangled from CRLF to CRCRLF if data->set.crlf or data->set.prefer_ascii are set (depending on CURL_DO_LINEEND_CONV). - Applied David McCreedy's patch to fix test suite harness to allow test FTP server and client on different machines, providing FTP client address when running the FTP test server. Daniel Fandrich (3 May 2009) - Added and disabled test case 563 which shows KNOWN_BUGS #59. The bug report failed to mention that a proxy must be used to reproduce it. Yang Tse (2 May 2009) - Use a build-time configured curl_socklen_t data type instead of socklen_t. Yang Tse (1 May 2009) - Applied David McCreedy's patches "TPF-platform specific changes to various files" and "http.c fix to Curl_proxyCONNECT for non-ASCII platforms", the former with minor edits. Daniel Stenberg (30 Apr 2009) - I was going to fix issue #59 in KNOWN_BUGS If the CURLOPT_PORT option is used on an FTP URL like "ftp://example.com/file;type=A" the ";type=A" is stripped off. I added test case 562 to verify, only to find out that I couldn't repeat this bug so I hereby consider it not a bug anymore! Daniel Stenberg (29 Apr 2009) - Based on bug report #2723219 (http://curl.haxx.se/bug/view.cgi?id=2723219) I've now made TFTP "connections" not being kept for re-use within libcurl. TFTP is UDP-based so the benefit was really low (if even existing) to begin with so instead of tracking down to fix this problem we instead removed the re-use. I also enabled test case 1099 that I wrote a few days ago to verify that this change fixes the reported problem. Daniel Stenberg (28 Apr 2009) - Constantine Sapuntzakis filed bug report #2783090 (http://curl.haxx.se/bug/view.cgi?id=2783090) pointing out that on windows we need to grow the SO_SNDBUF buffer somewhat to get really good upload speeds. http://support.microsoft.com/kb/823764 has the details. Friends confirmed that simply adding 32 to CURL_MAX_WRITE_SIZE is enough. - Bug report #2709004 (http://curl.haxx.se/bug/view.cgi?id=2709004) by Tim Chen pointed out how curl couldn't upload with resume when reading from a pipe. This ended up with the introduction of a new return code for the CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but that libcurl may try to resolve the situation anyway. In our case this means libcurl will attempt to instead read that much data from the stream instead of seeking and that way curl can now upload with resume when data is read from a stream! Daniel Stenberg (26 Apr 2009) - Bug report #2779733 (http://curl.haxx.se/bug/view.cgi?id=2779733) by Sven Wegener pointed out that CURLINFO_APPCONNECT_TIME didn't work with the multi interface and provided a patch that fixed the problem! Daniel Stenberg (24 Apr 2009) - Kamil Dudka fixed another NSS-related leak when client certs were used. - Bug report #2779245 (http://curl.haxx.se/bug/view.cgi?id=2779245) by Rainer Koenig pointed out that the man page didn't tell that the *_proxy environment variables can be specified lower case or UPPER CASE and the lower case takes precedence, Daniel Fandrich (21 Apr 2009) - Added new libcurl source files to Amiga, RiscOS and VC6 build files. Yang Tse (21 Apr 2009) - Moved potential inclusion of system's malloc.h and memory.h header files to setup_once.h. Inclusion of each header file is based on the definition of NEED_MALLOC_H and NEED_MEMORY_H respectively. Renamed libcurl's memory.h to curl_memory.h Daniel Stenberg (20 Apr 2009) - Leanic Lefever reported a crash and did some detailed research on why and how it occurs (http://curl.haxx.se/mail/lib-2009-04/0289.html). The conclusion was that if an error is detected and Curl_done() is called for the connection, ftp_done() could at times return another error code that then would take precedence and that new code confused existing logic that works for the first error code (CURLE_SEND_ERROR) only. - Gisle Vanem noticed that --libtool would produce bogus strings at times for OBJECTPOINT options. Now we've introduced a new function - my_setopt_str - within the app for setting plain string options to avoid the risk of this mistake happening. Daniel Stenberg (17 Apr 2009) - Pramod Sharma reported and tracked down a bug when doing FTP over a HTTP proxy. libcurl would then wrongly close the connection after each request. In his case it had the weird side-effect that it killed NTLM auth for the proxy causing an inifinite loop! I added test case 1098 to verify this fix. The test case does however not properly verify that the transfers are done persistently - as I couldn't think of a clever way to achieve it right now - but you need to read the stderr output after a test run to see that it truly did the right thing. Daniel Stenberg (13 Apr 2009) - bug report #2727981 (http://curl.haxx.se/bug/view.cgi?id=2727981) by Martin Storsjö pointed out how setting CURLOPT_NOBODY to 0 could be downright confusing as it set the method to either GET or HEAD. The example he showed looked like: curl_easy_setopt(curl, CURLOPT_PUT, 1); curl_easy_setopt(curl, CURLOPT_NOBODY, 0); The new way doesn't alter the method until the request is about to start. If CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is 0 and the request happens to have been set to HEAD, it will then instead be set to GET. I believe this will be less surprising to users, and hopefully not hit any existing users badly. - Toshio Kuratomi reported a memory leak problem with libcurl+NSS that turned out to be leaking cacerts. Kamil Dudka helped me complete the fix. The issue is found in Redhat's bug tracker: https://bugzilla.redhat.com/show_bug.cgi?id=453612 There are still memory leaks present, but they seem to have other reasons. Daniel Fandrich (11 Apr 2009) - Added new libcurl source files to Symbian OS build files. - Improved Symbian support for SSL. Yang Tse (10 Apr 2009) - Daniel Johnson improved the MacOSX-Framework shell script to now perform all the steps required to build a Mac OS X four way fat ppc/i386/ppc64/x86_64 libcurl.framework. Four way fat framework requires OS X 10.5 SDK or later. Yang Tse (8 Apr 2009) - Removed Sun compilers preprocessor block from curlbuild.h.dist, this also removes it from the curlbuild.h file originally distributed by the cURL project as this file is intended for systems not capable of running the configure script. For those who have been building curl out of the source code curl distribution tarball provided by curl.haxx.se the change implies nothing. Previous change in this area committed 2 Apr becomes irrelevant. Daniel Stenberg (6 Apr 2009) - I clarified in the docs that CURLOPT_SEEKFUNCTION should return 0 on success and 1 on fatal errors. Previously it only mentioned non-zero on fatal errors. This is a slight change in meaning, but it follows what we've done elsewhere before and it opens up for LOTS of more useful return codes whenever we can think of them... Yang Tse (2 Apr 2009) - Fix curl_off_t definition for builds done using Sun compilers and a non-configured libcurl. In this case curl_off_t data type was gated to the off_t data type which depends on the _FILE_OFFSET_BITS. This configuration is exactly the unwanted configuration for our curl_off_t data type which must not depend on such setting. This breaks ABI for libcurl libraries built with Sun compilers which were built without having run the configure script with _FILE_OFFSET_BITS different than 64 and using the ILP32 data model. Daniel Stenberg (1 Apr 2009) - Andre Guibert de Bruet fixed a NULL pointer use in an infof() call if a strdup() call failed. Daniel Fandrich (31 Mar 2009) - Properly return an error code in curl_easy_recv (reported by Jim Freeman). Daniel Stenberg (18 Mar 2009) - Kamil Dudka brought a patch that enables 6 additional crypto algorithms when NSS is used. These ciphers were added in NSS 3.4 and require to be enabled explicitly. Daniel Stenberg (13 Mar 2009) - Use libssh2_version() to present the libssh2 version in case the libssh2 library is found to support it. Yang Tse (12 Mar 2009) - Added missing Curl_read() return code checking in TELNET transfers. - Pierre Brico found and fixed TELNET transfers not being aborted upon a write callback failure. Daniel Stenberg (11 Mar 2009) - Kamil Dudka made the curl tool properly call curl_global_init() before any other libcurl function. Yang Tse (11 Mar 2009) - Added missing TELNET timeout support for Windows builds. This issue was reported by Pierre Brico. Daniel Stenberg (9 Mar 2009) - Frank Hempel found out a bug and provided the fix: curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE option. It only enabled the cookie engine in the destination handle if data->cookies is not NULL (where data is the source handle). In case of a newly initialized handle which just had the cookie support enabled by a curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was still NULL because the setopt-call only appends the value to data->change.cookielist, hence duplicating this handle would not have the cookie engine switched on. We also concluded that the slist-functionality would be suitable for being put in its own module rather than simply hanging out in lib/sendf.c so I created lib/slist.[ch] for them. - Andreas Farber made the 'buildconf' script check for the presence of m4 scripts to make it detect a bad checkout earlier. People with older checkouts who don't do cvs update with the -d option won't get the new dirs and then will get funny outputs that can be a bit hard to understand and fix. Daniel Stenberg (8 Mar 2009) - Andre Guibert de Bruet found and fixed a code segment in ssluse.c where the allocation of the memory BIO was not being properly checked. - Andre Guibert de Bruet fixed the gnutls-using code: There are a few places in the gnutls code where we were checking for negative values for errors, when the man pages state that GNUTLS_E_SUCCESS is returned on success and other values indicate error conditions. - Bill Egert pointed out (http://curl.haxx.se/bug/view.cgi?id=2671602) that curl didn't use sprintf() in a way that is documented to work in POSIX but since we use our own printf() code (from libcurl) that shouldn't be a problem. Nonetheless I modified the code to not rely on such particular features and to not cause further raised eyebrowse with no good reason. Daniel Fandrich (5 Mar 2009) - Expanded the security section of the libcurl-tutorial man page to cover more issues for authors to consider when writing robust libcurl-using applications. Yang Tse (5 Mar 2009) - Fixed NTLM authentication memory leak on SSPI enabled Windows builds. This issue was noticed by Chris Deidun. Daniel Fandrich (4 Mar 2009) - Fixed a problem with m4 quoting in the OpenSSL configure check reported by Daniel Johnson. Daniel Stenberg (3 Mar 2009) - David James brought a patch that make libcurl close (all) dead connections whenever you attempt to open a new connection. 1. After cleaning up a dead connection, "continue" instead of returning FALSE. This ensures that we clean up all dead connections, rather than just cleaning up the first dead connection. 2. Move up the cleanup for dead connections so that it occurs for all connections, rather than just the connections which have the same preferences as our current new connection. Version 7.19.4 (3 March 2009) Daniel Stenberg (3 Mar 2009) - David Kierznowski notified us about a security flaw (http://curl.haxx.se/docs/adv_20090303.html also known as CVE-2009-0037) in which previous libcurl versions (by design) can be tricked to access an arbitrary local/different file instead of a remote one when CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release together this the addition of two new setopt options for controlling this new behavior: o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option excludes the FILE and SCP protocols and thus you nee to explicitly allow them in your app if you really want that behavior. o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch using the primary URL option. This is useful if you want to allow a user or other outsiders control what URL to pass to libcurl and yet not allow all protocols libcurl may have been built to support. Daniel Stenberg (27 Feb 2009) - Senthil Raja Velu reported a problem when CURLOPT_INTERFACE and CURLOPT_LOCALPORT were used together (the local port bind failed), and Markus Koetter provided the fix! Daniel Stenberg (25 Feb 2009) - As Daniel Fandrich figured out, we must do the GnuTLS initing in the curl_global_init() function to properly maintain the performing functions thread-safe. We've previously (28 April 2007) moved the init to a later time just to avoid it to fail very early when libgcrypt dislikes the situation, but that move was bad and the fix should rather be in libgcrypt or elsewhere. Daniel Stenberg (24 Feb 2009) - Brian J. Murrell found out that Negotiate proxy authentication didn't work. It happened because the code used the struct for server-based auth all the time for both proxy and server auth which of course was wrong. Daniel Stenberg (23 Feb 2009) - After a bug reported by James Cheng I've made curl_easy_getinfo() for CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return -1 if the sizes aren't know. Previously these returned 0, make it impossible to detect the difference between actually zero and unknown. Yang Tse (23 Feb 2009) - Daniel Johnson provided a shell script that will perform all the steps needed to build a Mac OS X fat ppc/i386 or ppc64/x86_64 libcurl.framework Daniel Stenberg (23 Feb 2009) - I renamed everything in the windows builds files that used the name 'curllib' to the proper 'libcurl' as clearly this caused confusion. Yang Tse (20 Feb 2009) - Do not halt compilation when using VS2008 to build a Windows 2000 target. Daniel Stenberg (20 Feb 2009) - Linus Nielsen Feltzing reported and helped me repeat and fix a problem with FTP with the multi interface: when a transfer fails, like when aborted by a write callback, the control connection was wrongly closed and thus not re-used properly. This change is also an attempt to cleanup the code somewhat in this area, as now the FTP code attempts to keep (better) track on pending responses necessary to get read in ftp_done(). Daniel Stenberg (19 Feb 2009) - Patrik Thunstrom reported a problem and helped me repeat it. It turned out libcurl did a superfluous 1000ms wait when doing SFTP downloads! We read data with libssh2 while doing the "DO" operation for SFTP and then when we were about to start getting data for the actual file part, the "TRANSFER" part, we waited for socket action (in 1000ms) before doing a libssh2-read. But in this case libssh2 had already read and buffered the data so we ended up always just waiting 1000ms before we get working on the data! Patrick Monnerat (18 Feb 2009) - FTP downloads (i.e.: RETR) ending with code 550 now return error CURLE_REMOTE_FILE_NOT_FOUND instead of CURLE_FTP_COULDNT_RETR_FILE. Daniel Stenberg (17 Feb 2009) - Kamil Dudka made NSS-powered builds compile and run again! - A second follow-up change by Andre Guibert de Bruet to fix a related memory leak like that fixed on the 14th. When zlib returns failure, we need to cleanup properly before returning error. - CURLOPT_FTP_CREATE_MISSING_DIRS can now be set to 2 in addition to 1 for plain FTP connections, and it will then allow MKD to fail once and retry the CWD afterwards. This is especially useful if you're doing many simultanoes connections against the same server and they all have this option enabled, as then CWD may first fail but then another connection does MKD before this connection and thus MKD fails but trying CWD works! The numbers can (should?) now be set with the convenience enums now called CURLFTP_CREATE_DIR and CURLFTP_CREATE_DIR_RETRY. Tests has proven that if you're making an application that uploads a set of files to an ftp server, you will get a noticable gain in speed if you're using multiple connections and this option will be then be very useful. Daniel Stenberg (14 Feb 2009) - Andre Guibert de Bruet found and fixed a memory leak in the content encoding code, which could happen on libz errors. Daniel Fandrich (12 Feb 2009) - Added support for Digest and NTLM authentication using GnuTLS. Daniel Stenberg (11 Feb 2009) - CURLINFO_CONDITION_UNMET was added to allow an application to get to know if the condition in the previous request was unmet. This is typically a time condition set with CURLOPT_TIMECONDITION and was previously not possible to reliably figure out. From bug report #2565128 (http://curl.haxx.se/bug/view.cgi?id=2565128) filed by Jocelyn Jaubert. Daniel Fandrich (4 Feb 2009) - Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS (respectively) when --with-ssl=/usr is used (patch based on FreeBSD). - Added an explicit buffer limit check in msdosify() (patch based on FreeBSD). This couldn't ever overflow in curl, but might if the code were used elsewhere or under different conditions. Daniel Stenberg (3 Feb 2009) - Hidemoto Nakada provided a small fix that makes it possible to get the CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with CURLOPT_NOBODY set true. Daniel Stenberg (2 Feb 2009) - Patrick Scott found a rather large memory leak when using the multi interface and setting CURLMOPT_MAXCONNECTS to something less than the number of handles you add to the multi handle. All the connections that didn't fit in the cache would not be properly disconnected nor freed! - Craig A West brought us: libcurl now defaults to do CONNECT with HTTP version 1.1 instead of 1.0 like before. This change also introduces the new proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0 option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0. I updated all test cases cases that use CONNECT and I tried to do some using --proxy1.0 and some updated to do CONNECT 1.1 to get both versions run. Daniel Stenberg (31 Jan 2009) - When building with c-ares 1.6.1 (not yet released) or later and IPv6 support enabled, we can now take advantage of its brand new AF_UNSPEC support in ares_gethostbyname(). This makes test case 241 finally run fine for me with this setup since it now parses the "::1 ip6-localhost" line fine in my /etc/hosts file! Daniel Stenberg (30 Jan 2009) - Scott Cantor filed bug report #2550061 (http://curl.haxx.se/bug/view.cgi?id=2550061) mentioning that I failed to properly make sure that the VC9 makefiles got included in the latest release. I've now fixed the release script and verified it so next release will hopefully include them properly! Daniel Fandrich (30 Jan 2009) - Fixed --disable-proxy for FTP and SOCKS. Thanks to Daniel Egger for reporting. Yang Tse (29 Jan 2009) - Introduced curl_sspi.c and curl_sspi.h for the implementation of functions Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c Also adjusted socks_sspi.c to remove the link-time dependency on the Windows SSPI library using it now in the same way as it was done in http_ntlm.c. Daniel Stenberg (28 Jan 2009) - Markus Moeller introduced two new options to libcurl: CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl to do GSS-style authentication with SOCKS5 proxies. The curl tool got the options called --socks5-gssapi-service and --socks5-gssapi-nec to enable these. Daniel Stenberg (26 Jan 2009) - Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app to set desired block size to use for TFTP transfers instead of the default 512 bytes. - The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to disable "rfc4507bis session ticket support". rfc4507bis was later turned into the proper RFC5077 it seems: http://tools.ietf.org/html/rfc5077 The enabled extension concerns the session management. I wonder how often libcurl stops a connection and then resumes a TLS session. also, sending the session data is some overhead. .I suggest that you just use your proposed patch (which explicitly disables TICKET). If someone writes an application with libcurl and openssl who wants to enable the feature, one can do this in the SSL callback. Sharad Gupta brought this to my attention. Peter Sylvester helped me decide on the proper action. - Alexey Borzov filed bug report #2535504 (http://curl.haxx.se/bug/view.cgi?id=2535504) pointing out that realms with quoted quotation marks in HTTP Digest headers didn't work. I've now added test case 1095 that verifies my fix. - Craig A West brought CURLOPT_NOPROXY and the corresponding --noproxy option. They basically offer the same thing the NO_PROXY environment variable only offered previously: list a set of host names that shall not use the proxy even if one is specified. Daniel Fandrich (20 Jan 2009) - Call setlocale() for libtest tests to test the effects of locale-induced libc changes on libcurl. - Fixed a couple more locale-dependent toupper conversions, mainly for clarity. This does fix one problem that causes ;type=i FTP URLs to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is used (test case 561) - Added tests 561 and 1091 through 1094 to test various combinations of ;type= and ;mode= URLs that could potentially fail in the Turkish locale. Daniel Stenberg (20 Jan 2009) - Lisa Xu pointed out that the ssh.obj file was missing from the lib/Makefile.vc6 file (and thus from the vc8 and vc9 ones too). Version 7.19.3 (19 January 2009) Daniel Stenberg (16 Jan 2009) - Andrew de los Reyes fixed curlbuild.h for "generic" gcc builds on PPC, both 32 bit and 64 bit. Daniel Stenberg (15 Jan 2009) - Tim Ansell fixed a compiler warning in lib/cookie.c Daniel Stenberg (14 Jan 2009) - Grant Erickson fixed timeouts for TFTP such that specifying a connect-timeout, a max-time or both options work correctly and as expected by passing the correct boolean value to Curl_timeleft via the 'duringconnect' parameter. With this small change, curl TFTP now behaves as expected (and likely as originally-designed): 1) For non-existent or unreachable dotted IP addresses: a) With no options, follows the default curl 300s timeout... b) With --connect-timeout only, follows that value... c) With --max-time only, follows that value... d) With both --connect-timeout and --max-time, follows the smaller value... and times out with a "curl: (7) Couldn't connect to server" error. 2) For transfers to/from a valid host: a) With no options, follows default curl 300s timeout for the first XRQ/DATA/ACK transaction and the default TFTP 3600s timeout for the remainder of the transfer... b) With --connect-time only, follows that value for the first XRQ/DATA/ACK transaction and the default TFTP 3600s timeout for the remainder of the transfer... c) With --max-time only, follows that value for the first XRQ/DATA/ACK transaction and for the remainder of the transfer... d) With both --connect-timeout and --max-time, follows the former for the first XRQ/DATA/ACK transaction and the latter for the remainder of the transfer... and times out with a "curl: (28) Timeout was reached" error as appropriate. Daniel Stenberg (13 Jan 2009) - Michael Wallner fixed a NULL pointer deref when calling curl_easy_setup(curl, CURLOPT_COOKIELIST, "SESS") on a CURL handle with no cookies data. - Stefan Teleman brought a patch to fix the default curlbuild.h file for the SunPro compilers. Daniel Stenberg (12 Jan 2009) - Based on bug report #2498665 (http://curl.haxx.se/bug/view.cgi?id=2498665) by Daniel Black, I've now added magic to the configure script that makes it use pkg-config to detect gnutls details as well if the existing method (using libgnutls-config) fails. While doing this, I cleaned up and unified the pkg-config usage when detecting openssl and nss as well. Daniel Stenberg (11 Jan 2009) - Karl Moerder brought the patch that creates vc9 Makefiles, and I made 'maketgz' now use the actual makefile targets to do the VC8 and VC9 makefiles. Daniel Stenberg (10 Jan 2009) - Emil Romanus fixed: When using the multi interface over HTTP and the server returns a Location header, the running easy handle will get stuck in the CURLM_STATE_PERFORM state, leaving the external event loop stuck waiting for data from the ingoing socket (when using the curl_multi_socket_action stuff). While this bug was pretty hard to find, it seems to require only a one-line fix. The break statement on line 1374 in multi.c caused the function to skip the call to multistate(). How to reproduce this bug? Well, that's another question. evhiperfifo.c in the examples directory chokes on this bug only _sometimes_, probably depending on how fast the URLs are added. One way of testing the bug out is writing to hiper.fifo from more than one source at the same time. Daniel Fandrich (7 Jan 2009) - Unified much of the SessionHandle initialization done in Curl_open() and curl_easy_reset() by creating Curl_init_userdefined(). This had the side effect of fixing curl_easy_reset() so it now also resets CURLOPT_FTP_FILEMETHOD and CURLOPT_SSL_SESSIONID_CACHE Daniel Stenberg (7 Jan 2009) - Rob Crittenden did once again provide an NSS update: I have to jump through a few hoops now with the NSS library initialization since another part of an application may have already initialized NSS by the time Curl gets invoked. This patch is more careful to only shutdown the NSS library if Curl did the initialization. It also adds in a bit of code to set the default ciphers if the app that call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific ciphers. One might argue that this lets other application developers get lazy and/or they aren't using the NSS API correctly, and you'd be right. But still, this will avoid terribly difficult-to-trace crashes and is generally helpful. Daniel Stenberg (1 Jan 2009) - 'reconf' is removed since we rather have users use 'buildconf' Daniel Stenberg (31 Dec 2008) - Bas Mevissen reported http://curl.haxx.se/bug/view.cgi?id=2479030 pointing out that 'reconf' didn't properly point out the m4 subdirectory when running aclocal. Daniel Stenberg (29 Dec 2008) - Phil Lisiecki filed bug report #2413067 (http://curl.haxx.se/bug/view.cgi?id=2413067) that identified a problem that would cause libcurl to mark a DNS cache entry "in use" eternally if the subsequence TCP connect failed. It would thus never get pruned and refreshed as it should've been. Phil provided his own patch to this problem that while it seemed to work wasn't complete and thus I wrote my own fix to the problem. Daniel Stenberg (28 Dec 2008) - Peter Korsgaard fixed building libcurl with "configure --with-ssl --disable-verbose". - Anthony Bryan fixed more language and spelling flaws in man pages. Daniel Stenberg (22 Dec 2008) - Given a recent enough libssh2, libcurl can now seek/resume with SFTP even on file indexes beyond 2 or 4GB. - Anthony Bryan provided a set of patches that cleaned up manual language, corrected spellings and more. Daniel Stenberg (20 Dec 2008) - Igor Novoseltsev fixed a bad situation for the multi_socket() API when doing pipelining, as libcurl could then easily get confused and A) work on the handle that was not "first in queue" on a pipeline, or even B) tell the app to REMOVE a socket while it was in use by a second handle in a pipeline. Both errors caused hanging or stalling applications. Daniel Stenberg (19 Dec 2008) - curl_multi_timeout() could return a timeout value of 0 even though nothing was actually ready to get done, as the internal time resolution is higher than the returned millisecond timer. Therefore it could cause applications running on fast processors to do short bursts of busy-loops. curl_multi_timeout() will now only return 0 if the timeout is actually alreay triggered. - Using the libssh2 0.19 function libssh2_session_block_directions(), libcurl now has an improved ability to do right when the multi interface (both "regular" and multi_socket) is used for SCP and SFTP transfers. This should result in (much) less busy-loop situations and thus less CPU usage with no speed loss. Daniel Stenberg (17 Dec 2008) - SCP and SFTP with the multi interface had the same flaw: the 'DONE' operation didn't complete properly if the EAGAIN equivalent was returned but libcurl would simply continue with a half-completed close operation performed. This ruined persistent connection re-use and cause some SSH-protocol errors in general. The correction is unfortunately adding a blocking function - doing it entirely non-blocking should be considered for a better fix. Gisle Vanem (16 Dec 2008) - Added the possibility to use the Watt-32 tcp/ip stack under Windows. The change simply involved adding a USE_WATT32 section in the config-win32.h files (under ./lib and ./src). This section disables the use of any Winsock headers. Daniel Stenberg (16 Dec 2008) - libssh2_sftp_last_error() was wrongly used at some places in libcurl which made libcurl sometimes not properly abort problematic SFTP transfers. Daniel Stenberg (12 Dec 2008) - More work with Igor Novoseltsev to first fix the remaining stuff for removing easy handles from multi handles when the easy handle is/was within a HTTP pipeline. His bug report #2351653 (http://curl.haxx.se/bug/view.cgi?id=2351653) was also related and was eventually fixed by a patch by Igor himself. Yang Tse (12 Dec 2008) - Patrick Monnerat fixed a build regression, introduced in 7.19.2, affecting OS/400 compilations with IPv6 enabled. Daniel Stenberg (12 Dec 2008) - Mark Karpeles filed bug report #2416182 titled "crash in ConnectionExists when using duphandle+curl_mutli" (http://curl.haxx.se/bug/view.cgi?id=2416182) which showed that curl_easy_duphandle() wrongly also copied the pointer to the connection cache, which was plain wrong and caused a segfault if the handle would be used in a different multi handle than the handle it was duplicated from. Daniel Stenberg (11 Dec 2008) - Keshav Krity found out that libcurl failed to deal with dotted IPv6 addresses if they were very long (>39 letters) due to a too strict address validity parser. It now accepts addresses up to 45 bytes long. Daniel Stenberg (11 Dec 2008) - Internet Explorer had a broken HTTP digest authentication before v7 and there are servers "out there" that relies on the client doing this broken Digest authentication. Apache even comes with an option to work with such broken clients. The difference is only for URLs that contain a query-part (a '?'-letter and text to the right of it). libcurl now supports this quirk, and you enable it by setting the CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or CURLOPT_PROXYAUTH options. They are thus individually controlled to server and proxy. (note that there's no way to activate this with the curl tool yet) Daniel Fandrich (9 Dec 2008) - Added test cases 1089 and 1090 to test --write-out after a redirect to test a report that the size didn't work, but these test cases pass. - Documented CURLOPT_CONNECT_ONLY as being useful only on HTTP URLs. Daniel Stenberg (9 Dec 2008) - Ken Hirsch simplified how libcurl does FTPS: now it doesn't assume any particular state for the control connection like it did before for implicit FTPS (libcurl assumed such control connections to be encrypted while some FTPS servers such as FileZilla assumes such connections to be clear mode). Use the CURLOPT_USE_SSL option to set your desired level. Daniel Stenberg (8 Dec 2008) - Fred Machado posted about a weird FTP problem on the curl-users list and when researching it, it turned out he got a 550 response back from a SIZE command and then I fell over the text in RFC3659 that says: The presence of the 550 error response to a SIZE command MUST NOT be taken by the client as an indication that the file cannot be transferred in the current MODE and TYPE. In other words: the change I did on September 30th 2008 and that has been included in the last two releases were a regression and a bad idea. We MUST NOT take a 550 response from SIZE as a hint that the file doesn't exist. - Christian Krause filed bug #2221237 (http://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite loop during GSS authentication given some specific conditions. With his patience and great feedback I managed to narrow down the problem and eventually fix it although I can't test any of this myself! Daniel Fandrich (3 Dec 2008) - Fixed the getifaddrs version of Curl_if2ip to work on systems without IPv6 support (e.g. Minix) Daniel Stenberg (3 Dec 2008) - Igor Novoseltsev filed bug #2351645 (http://curl.haxx.se/bug/view.cgi?id=2351645) that identified a problem with the multi interface that occured if you removed an easy handle while in progress and the handle was used in a HTTP pipeline. - Pawel Kierski pointed out a mistake in the cookie code that could lead to a bad fclose() after a fatal error had occured. (http://curl.haxx.se/bug/view.cgi?id=2382219) Daniel Fandrich (25 Nov 2008) - If a HTTP request is Basic and num is already >=1000, the HTTP test server adds 1 to num to get the data section to return. This allows testing authentication negotiations using the Basic authentication method. - Added tests 1087 and 1088 to test Basic authentication on a redirect with and without --location-trusted Daniel Stenberg (24 Nov 2008) - Based on a patch by Vlad Grachov, libcurl now uses a new libssh2 0.19 function when built to support SCP and SFTP that helps the library to know in which direction a particular libssh2 operation would return EAGAIN so that libcurl knows what socket conditions to wait for before trying the function call again. Previously (and still when using libssh2 0.18 or earlier), libcurl will busy-loop in this situation when the easy interface is used! Daniel Fandrich (20 Nov 2008) - Automatically detect OpenBSD's CA cert bundle. Daniel Stenberg (19 Nov 2008) - I removed the default use of "Pragma: no-cache" from libcurl when a proxy is used. It has been used since forever but it was never a good idea to use unless explicitly asked for. - Josef Wolf's extension that allows a $TESTDIR/gdbinit$testnum file that when you use runtests.pl -g, will be sourced by gdb to allow additional fancy or whatever you see fit - Christian Krause reported and fixed a memory leak that would occur with HTTP GSS/kerberos authentication (http://curl.haxx.se/bug/view.cgi?id=2284386) - Andreas Wurf and Markus Koetter helped me analyze a problem that Andreas got when uploading files to a single FTP server using multiple easy handle handles with the multi interface. Occasionally a handle would stall in mysterious ways. The problem turned out to be a side-effect of the ConnectionExists() function's eagerness to re-use a handle for HTTP pipelining so it would select it even if already being in use, due to an inadequate check for its chances of being used for pipelnining. Daniel Fandrich (17 Nov 2008) - Added more compiler warning options for gcc 4.3 Yang Tse (17 Nov 2008) - Fix a remaining problem in the inet_pton() runtime configure check. And fix internal Curl_inet_pton() failures to reject certain malformed literals. - Make configure script check if ioctl with the SIOCGIFADDR command can be used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate. Daniel Stenberg (16 Nov 2008) - Christian Krause fixed a build failure when building with gss support enabled and FTP disabled. - Added check for NULL returns from strdup() in src/main.c and lib/formdata.c - reported by Jim Meyering also prevent buffer overflow on MSDOS when you do for example -O on a url with a file name part longer than PATH_MAX letters - lib/nss.c fixes based on the report by Jim Meyering: I went over and added checks for return codes for all calls to malloc and strdup that were missing. I also changed a few malloc(13) to use arrays on the stack and a few malloc(PATH_MAX) to instead use aprintf() to lower memory use. - I fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is in use. Daniel Fandrich (14 Nov 2008) - Added .xml as one of the few common file extensions known by the multipart form generator. - Added some #ifdefs around header files and change the EAGAIN test to fix compilation on Cell (reported by Jeff Curley). Yang Tse (14 Nov 2008) - Fixed several configure script issues affecting checks for inet_ntoa_r(), inet_ntop(), inet_pton(), getifaddrs(), fcntl() and getaddrinfo(). Yang Tse (13 Nov 2008) - Refactored configure script detection of functions used to set sockets into non-blocking mode, and decouple function detection from function capability.
