9 Daniel Stenberg (21 Jan 2010)
10 - Chris Conroy brought support for RTSP transfers, and with it comes 8(!) new
11 libcurl options for controlling what to get and how to receive posssibly
14 Daniel Stenberg (20 Jan 2010)
15 - As was pointed out on the http-state mailing list, the order of cookies in a
16 HTTP Cookie: header _needs_ to be sorted on the path length in the cases
17 where two cookies using the same name are set more than once using
18 (overlapping) paths. Realizing this, identically named cookies must be
19 sorted correctly. But detecting only identically named cookies and take care
20 of them individually is harder than just to blindly and unconditionally sort
21 all cookies based on their path lengths. All major browsers also already do
22 this, so this makes our behavior one step closer to them in the cookie area.
24 Test case 8 was the only one that broke due to this change and I updated it
27 Daniel Stenberg (19 Jan 2010)
28 - David McCreedy brought a fix and a new test case (129) to make libcurl work
29 again when downloading files over FTP using ASCII and it turns out that the
30 final size of the file is not the same as the initial size the server
31 reported. This is very common since servers don't take the newline
32 conversions into account.
34 Kamil Dudka (14 Jan 2010)
35 - Suppressed side effect of OpenSSL configure checks, which prevented NSS from
36 being properly detected under certain circumstances. It had been caused by
37 strange behavior of pkg-config when handling PKG_CONFIG_LIBDIR. pkg-config
38 distinguishes among empty and non-existent environment variable in that case.
40 Daniel Stenberg (12 Jan 2010)
41 - Gil Weber reported a peculiar flaw with the multi interface when doing SFTP
42 transfers: curl_multi_fdset() would return -1 and not set and file
43 descriptors several times during a transfer of a single file. It turned out
44 to be due to two different flaws now fixed. Gil's excellent recipe helped me
47 Daniel Stenberg (11 Jan 2010)
48 - Made sure that the progress callback is repeatedly called at a regular
49 interval even during very slow connects.
51 - The tests/runtests.pl script now checks to see if the test case that runs is
52 present in the tests/data/Makefile.am and outputs a notice message on the
53 screen if not. Each test file has to be included in that Makefile.am to get
54 included in release archives and forgetting to add files there is a common
55 mistake. This is an attempt to make it harder to forget.
57 Daniel Stenberg (9 Jan 2010)
58 - Johan van Selst found and fixed a OpenSSL session ref count leak:
60 ossl_connect_step3() increments an SSL session handle reference counter on
61 each call. When sessions are re-used this reference counter may be
62 incremented many times, but it will be decremented only once when done (by
63 Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
64 if this reference count remains positive. When a session is re-used the
65 reference counter should be corrected by explicitly calling
66 SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
67 introducing a memory leak.
69 (http://curl.haxx.se/bug/view.cgi?id=2926284)
71 Daniel Stenberg (7 Jan 2010)
72 - Make sure the progress callback is called repeatedly even during very slow
73 name resolves when c-ares is used for resolving.
75 Claes Jakobsson (6 Jan 2010)
76 - Julien Chaffraix fixed so that the fragment part in an URL is not sent
77 to the server anymore.
79 Kamil Dudka (3 Jan 2010)
80 - Julien Chaffraix eliminated a duplicated initialization in singlesocket().
82 Daniel Stenberg (2 Jan 2010)
83 - Make curl support --ssl and --ssl-reqd instead of the previous FTP-specific
84 versions --ftp-ssl and --ftp-ssl-reqd as these options are now used to
85 control SSL/TLS for IMAP, POP3 and SMTP as well in addition to FTP. The old
86 option names are still working but the new ones are the ones listed and
89 Daniel Stenberg (1 Jan 2010)
90 - Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This
91 command is a special "hack" used by the drftpd server, but even though it is
92 a custom extension I've deemed it fine to add to libcurl since this server
93 seems to survive and people keep using it and want libcurl to support
94 it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
95 usable from the curl tool with --ftp-pret. Using this option on a server
96 that doesn't support this command will make libcurl fail.
98 I added test cases 1107 and 1108 to verify the functionality.
100 The PRET command is documented at
101 http://www.drftpd.org/index.php/Distributed_PASV
103 Yang Tse (30 Dec 2009)
104 - Steven M. Schweda improved VMS build system, and Craig A. Berry helped
105 with the patch and testing.
107 Daniel Stenberg (26 Dec 2009)
108 - Renato Botelho and Peter Pentchev brought a patch that makes the libcurl
109 headers work correctly even on FreeBSD systems before v8.
111 (http://curl.haxx.se/bug/view.cgi?id=2916915)
113 Daniel Stenberg (17 Dec 2009)
114 - David Byron fixed Curl_ossl_cleanup to actually call ENGINE_cleanup when
117 - Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I
118 was a bit too quick and broke test case 1101 with that change. The order of
119 some of the setups is sensitive. I now changed it slightly again to make
120 sure we do them in this order:
122 1 - parse URL and figure out what protocol is used in the URL
123 2 - prepend protocol:// to URL if missing
124 3 - parse name+password off URL, which needs to know what protocol is used
125 (since only some allows for name+password in the URL)
126 4 - figure out if a proxy should be used set by an option
127 5 - if no proxy option, check proxy environment variables
128 6 - run the protocol-specific setup function, which needs to have the proxy
131 Daniel Stenberg (15 Dec 2009)
132 - Jon Nelson found a regression that turned out to be a flaw in how libcurl
133 detects and uses proxies based on the environment variables. If the proxy
134 was given as an explicit option it worked, but due to the setup order
135 mistake proxies would not be used fine for a few protocols when picked up
136 from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
137 test case 1106 that verifies this functionality.
139 (http://curl.haxx.se/bug/view.cgi?id=2913886)
141 Daniel Stenberg (12 Dec 2009)
142 - IMAP, POP3 and SMTP support and their TLS versions (including IMAPS, POP3S
143 and SMTPS) are now supported. The current state may not yet be solid, but
144 the foundation is in place and the test suite has some initial support for
145 these protocols. Work will now persue to make them nice libcurl citizens
148 The work with supporting these new protocols was sponsored by
149 networking4all.com - thanks!
151 Daniel Stenberg (10 Dec 2009)
152 - Siegfried Gyuricsko found out that the curl manual said --retry would retry
153 on FTP errors in the transient 5xx range. Transient FTP errors are in the
154 4xx range. The code itself only tried on 5xx errors that occured _at login_.
155 Now the retry code retries on all FTP transfer failures that ended with a
158 (http://curl.haxx.se/bug/view.cgi?id=2911279)
160 - Constantine Sapuntzakis figured out a case which would lead to libcurl
161 accessing alredy freed memory and thus crash when using HTTPS (with
162 OpenSSL), multi interface and the CURLOPT_DEBUGFUNCTION and a certain order
163 of cleaning things up. I fixed it.
165 (http://curl.haxx.se/bug/view.cgi?id=2905220)
167 Daniel Stenberg (7 Dec 2009)
168 - Martin Storsjo made libcurl use the Expect: 100-continue header for posts
169 with unknown size. Previously it was only used for posts with a known size
170 larger than 1024 bytes.
172 Daniel Stenberg (1 Dec 2009)
173 - If the Expect: 100-continue header has been set by the application through
174 curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
175 data->state.expect100header accordingly - the current code (in 7.19.7 at
176 least) doesn't handle this properly. Martin Storsjo provided the fix!
178 Yang Tse (28 Nov 2009)
179 - Added Diffie-Hellman parameters to several test harness certificate files in
180 PEM format. Required by several stunnel versions used by our test harness.
182 Daniel Stenberg (28 Nov 2009)
183 - Markus Koetter provided a polished and updated version of Chad Monroe's TFTP
184 rework patch that now integrates TFTP properly into libcurl so that it can
185 be used non-blocking with the multi interface and more. BLKSIZE also works.
187 The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
190 Daniel Stenberg (26 Nov 2009)
191 - Extended and fixed the change I did on Dec 11 for the the progress
192 meter/callback during FTP command/response sequences. It turned out it was
193 really lame before and now the progress meter SHOULD get called at least
196 Daniel Stenberg (23 Nov 2009)
197 - Bjorn Augustsson reported a bug which made curl not report any problems even
198 though it failed to write a very small download to disk (done in a single
199 fwrite call). It turned out to be because fwrite() returned success, but
200 there was insufficient error-checking for the fclose() call which tricked
201 curl to believe things were fine.
203 Yang Tse (23 Nov 2009)
204 - David Byron modified Makefile.dist vc8 and vc9 targets in order to allow
205 finer granularity control when generating src and lib makefiles.
207 Yang Tse (22 Nov 2009)
208 - I modified configure to force removal of the curlbuild.h file included in
209 distribution tarballs for use by non-configure systems. As intended, this
210 would get overwriten when doing in-tree builds. But VPATH builds would end
211 having two curlbuild.h files, one in the source tree and another in the
212 build tree. With the modification I introduced 5 Nov 2009 this could become
213 an issue when running libcurl's test suite.
215 Daniel Stenberg (20 Nov 2009)
216 - Constantine Sapuntzakis identified a write after close, as the sockets were
217 closed by libcurl before the SSL lib were shutdown and they may write to its
218 socket. Detected to at least happen with OpenSSL builds.
220 - Jad Chamcham pointed out a bug with connection re-use. If a connection had
221 CURLOPT_HTTPPROXYTUNNEL enabled over a proxy, a subsequent request using the
222 same proxy with the tunnel option disabled would still wrongly re-use that
223 previous connection and the outcome would only be badness.
225 Yang Tse (18 Nov 2009)
226 - I modified the memory tracking system to make it intolerant with zero sized
227 malloc(), calloc() and realloc() function calls.
229 Daniel Stenberg (17 Nov 2009)
230 - Constantine Sapuntzakis provided another fix for the DNS cache that could
231 end up with entries that wouldn't time-out:
233 1. Set up a first web server that redirects (307) to a http://server:port
235 2. Have curl connect to the first web server using curl multi
237 After the curl_easy_cleanup call, there will be curl dns entries hanging
238 around with in_use != 0.
240 (http://curl.haxx.se/bug/view.cgi?id=2891591)
242 - Marc Kleine-Budde fixed: curl saved the LDFLAGS set during configure into
243 its pkg-config file. So -Wl stuff ended up in the .pc file, which is really
244 bad, and breaks if there are multiple -Wl in our LDFLAGS (which are in
245 PTXdist). bug #2893592 (http://curl.haxx.se/bug/view.cgi?id=2893592)
247 Kamil Dudka (15 Nov 2009)
248 - David Byron improved the configure script to use pkg-config to find OpenSSL
249 (and in particular the list of required libraries) even if a path is given
250 as argument to --with-ssl
252 Claes Jakobsson (14 Nov 2009)
253 - curl-config now accepts '--configure' to see what arguments was
254 passed to the configure script when building curl.
256 Daniel Stenberg (14 Nov 2009)
257 - Claes Jakobsson restored the configure functionality to detect NSS when
258 --with-nss is set but not "yes".
260 I think we can still improve that to check for pkg-config in that path etc,
261 but at least this patch brings back the same functionality we had before.
263 - Camille Moncelier added support for the file type SSL_FILETYPE_ENGINE for
264 the client certificate. It also disable the key name test as some engines
265 can select a private key/cert automatically (When there is only one key
266 and/or certificate on the hardware device used by the engine)
268 Yang Tse (14 Nov 2009)
269 - Constantine Sapuntzakis provided the fix that ensures that an SSL connection
270 won't be reused unless protection level for peer and host verification match.
272 Kamil Dudka (12 Nov 2009)
273 - Kevin Baughman provided a fix preventing libcurl-NSS from crash on doubly
274 closed NSPR descriptor. The issue was hard to find, reported several times
275 before and always closed unresolved. More info at the RH bug:
276 https://bugzilla.redhat.com/534176
278 - libcurl-NSS now tries to reconnect with TLS disabled in case it detects
279 a broken TLS server. However it does not happen if SSL version is selected
280 manually. The approach was originally taken from PSM. Kaspar Brand helped me
281 to complete the patch. Original bug reports:
282 https://bugzilla.redhat.com/525496
283 https://bugzilla.redhat.com/527771
285 Yang Tse (12 Nov 2009)
286 - I modified configure script to make the getaddrinfo function check also
287 verify if the function is thread safe.
289 Yang Tse (11 Nov 2009)
290 - Marco Maggi reported that compilation failed when configured --with-gssapi
291 and GNU GSS installed due to a missing mutual exclusion of header files in
292 the Kerberos 5 code path. He also verified that my patch worked for him.
294 Daniel Stenberg (11 Nov 2009)
295 - Constantine Sapuntzakis posted bug #2891595
296 (http://curl.haxx.se/bug/view.cgi?id=2891595) which identified how an entry
297 in the DNS cache would linger too long if the request that added it was in
298 use that long. He also provided the patch that now makes libcurl capable of
299 still doing a request while the DNS hash entry may get timed out.
301 - Christian Schmitz noticed that the progress meter/callback was not properly
302 used during the FTP connection phase (after the actual TCP connect), while
303 it of course should be. I also made the speed check get called correctly so
304 that really slow servers will trigger that properly too.
306 Kamil Dudka (5 Nov 2009)
307 - Dropped misleading timeouts in libcurl-NSS and made sure the SSL socket works
308 in non-blocking mode.
310 Yang Tse (5 Nov 2009)
311 - I removed leading 'curl' path on the 'curlbuild.h' include statement in
312 curl.h, adjusting auto-makefiles include path, to enhance portability to
313 OS's without an orthogonal directory tree structure such as OS/400.
315 Daniel Stenberg (4 Nov 2009)
316 - I fixed several problems with the transfer progress meter. It showed the
317 wrong percentage for small files, most notable for <1000 bytes and could
318 easily end up showing more than 100% at the end. It also didn't show any
319 percentage, transfer size or estimated transfer times when transferring
322 Version 7.19.7 (4 November 2009)
324 Daniel Stenberg (2 Nov 2009)
325 - As reported independent by both Stan van de Burgt and Didier Brisebourg,
326 CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when
327 getting data from ldap!
329 Daniel Stenberg (31 Oct 2009)
330 - Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the
331 download was 0 bytes, as libcurl would then return the size as unknown (-1)
332 and not 0. I wrote a fix and test case 566 to verify it.
334 Daniel Stenberg (30 Oct 2009)
335 - Liza Alenchery mentioned a problem with re-used SCP connection when a bad
336 auth is used, as it caused a crash. I failed to repeat the issue, but still
337 made a change that now forces the TCP connection used for a freed SCP
338 session to get closed and not be re-used.
340 - "Tom" posted a bug report that mentioned how libcurl did wrong when doing a
341 POST using a read callback, with Digest authentication and
342 "Transfer-Encoding: chunked" enforced. I would then cause the first request
343 to be wrongly sent and then basically hang until the server closed the
344 connection. I fixed the problem and added test case 565 to verify it.
346 Daniel Stenberg (25 Oct 2009)
347 - Dima Barsky made the curl cookie parser accept cookies even with blank or
348 unparsable expiry dates and then treat them as session cookies - previously
349 libcurl would reject cookies with a date format it couldn't parse. Research
350 shows that the major browser treat such cookies as session cookies. I
351 modified test 8 and 31 to verify this.
353 Daniel Stenberg (21 Oct 2009)
354 - Attempt to use pkg-config for finding out libssh2 installation details
357 - A patch in bug report #2883177 (http://curl.haxx.se/bug/view.cgi?id=2883177)
358 by Johan van Selst introduced the --crlfile option to curl, which makes curl
359 tell libcurl about a file with CRL (certificate revocation list) data to
362 Daniel Stenberg (18 Oct 2009)
363 - Ray Dassen provided a patch in Debian's bug tracker (bug number #551461)
364 that now makes curl_getdate(3) actually handles RFC 822 formatted dates that
365 use the "single letter military timezones".
366 http://www.rfc-ref.org/RFC-TEXTS/822/chapter5.html has the details.
368 - Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts
371 - John Dennis filed bug report #2873666
372 (http://curl.haxx.se/bug/view.cgi?id=2873666) which identified a problem
373 which made libcurl loop infinitely when given incorrect credentials when
374 using HTTP GSS negotiate authentication. He also provided a small and simple
377 - Kevin Baughman found a double close() problem with libcurl-NSS, as when
378 libcurl called NSS to close the SSL "session" it also closed the actual
381 Yang Tse (17 Oct 2009)
382 - Bug report #2866724 indicated
383 (http://curl.haxx.se/bug/view.cgi?id=2866724) that curl on Windows failed
384 when writing files whose file names originally contained characters which
385 are not valid for file names on Windows. Dan Fandrich provided an initial
386 patch and another revised one to fix this issue.
388 Daniel Stenberg (1 Oct 2009)
389 - Tom Mueller correctly reported in bug report #2870221
390 (http://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an
391 incorrect return code from the internal trynextip() function which caused
392 him grief. This is a regression that was introduced in 7.19.1 and I find it
393 strange it hasn't hit us harder, but I won't persue into figuring out
396 - Constantine Sapuntzakis: The current implementation will always set
397 SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger. The
398 patch doesn't do a setsockopt if SO_SNDBUF is already greater than
399 CURL_WRITE_SIZE. This should help folks who have set up their computer with
402 Daniel Stenberg (27 Sep 2009)
403 - I introduced a maximum limit for received HTTP headers. It is controlled by
404 the define CURL_MAX_HTTP_HEADER which is even exposed in the public header
405 file to allow for users to fairly easy rebuild libcurl with a modified
406 limit. The rationale for a fixed limit is that libcurl is realloc()ing a
407 buffer to be able to put a full header into it, so that it can call the
408 header callback with the entire header, but that also risk getting it into
409 trouble if a server by mistake or willingly sends a header that is more or
410 less without an end. The limit is set to 100K.
412 Daniel Stenberg (26 Sep 2009)
413 - John P. McCaskey posted a bug report that showed how libcurl did wrong when
414 saving received cookies with no given path, if the path in the request had a
415 query part. That is means a question mark (?) and characters on the right
416 side of that. I wrote test case 1105 and fixed this problem.
418 Kamil Dudka (26 Sep 2009)
419 - Implemented a protocol independent way to specify blocking direction, used by
420 transfer.c for blocking. It is currently used only by SCP and SFTP protocols.
421 This enhancement resolves an issue with 100% CPU usage during SFTP upload,
424 Daniel Stenberg (25 Sep 2009)
425 - Chris Mumford filed bug report #2861587
426 (http://curl.haxx.se/bug/view.cgi?id=2861587) identifying that libcurl used
427 the OpenSSL function X509_load_crl_file() wrongly and failed if it would
428 load a CRL file with more than one certificate within. This is now fixed.
430 Daniel Stenberg (16 Sep 2009)
431 - Sven Anders reported that we introduced a cert verfication flaw for OpenSSL-
432 powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
433 field in the certficate it had to match and so even if non-DNS and non-IP
434 entry was present it caused the verification to fail.
436 Daniel Fandrich (15 Sep 2009)
437 - Moved the libssh2 checks after the SSL library checks. This helps when
438 statically linking since libssh2 needs the SSL library link flags to be
439 set up already to satisfy its dependencies. This wouldn't be necessary if
440 the libssh2 configure check was changed to use pkg-config since the
441 --static flag would add the dependencies automatically.
443 Yang Tse (14 Sep 2009)
444 - Revert Joshua Kwan's patch committed 11 Sep 2009.
446 Some systems poll function sets POLLHUP in revents without setting
447 POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
448 libcurl code execution paths this could trigger busy wait loops with
449 high CPU usage until a timeout condition aborted the loop.
451 The reverted patch addressed the above issue for a very specific case,
452 when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
455 Guenter Knauf (11 Sep 2009)
456 - Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
457 This fixes a loop problem with high CPU usage.
459 Daniel Stenberg (10 Sep 2009)
460 - Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch
461 start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
462 which internally then is treated as a session cookie. That particular date
463 is now made to get the value of 1.
465 Daniel Stenberg (2 Sep 2009)
466 - Daniel Johnson found a flaw in the code converting sftp-errors to libcurl
469 Daniel Stenberg (1 Sep 2009)
470 - Peter Sylvester made a debug feature for Curl_resolv() that now will force
471 libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
472 the --interface option to (exactly) "LocalHost". This will enable us to
473 write tests for custom hosts names but still use a local host server.
475 - configure now tries to use pkg-config for a number of sub-dependencies even
476 when cross-compiling. The key to success is then you properly setup
477 PKG_CONFIG_PATH before invoking configure.
479 I also improved how NSS is detected by trying nss-config if pkg-config isn't
480 present, and as a last resort just use the lib name and force the user to
481 setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
482 add a range of various libs that would almost never be quite correct.
484 Daniel Stenberg (31 Aug 2009)
485 - When using the multi interface with FTP and you asked for NOBODY, you did no
486 QUOTE commands and the request used the same path as the connection had
487 already changed to, it would decide that no commands would be necessary for
488 the "DO" action and that was not handled properly but libcurl would instead
491 Kamil Dudka (28 Aug 2009)
492 - Improved error message for not matching certificate subject name in
493 libcurl-NSS. Originally reported at:
494 https://bugzilla.redhat.com/show_bug.cgi?id=516056#c9
496 Patrick Monnerat (24 Aug 2009)
497 - Introduced a SYST-based test to properly set-up name format when dealing
498 with the OS/400 FTP server.
500 - Fixed an ftp_readresp() bug preventing detection of failing control socket
501 and causing FTP client to loop forever.
503 Daniel Stenberg (24 Aug 2009)
504 - Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work
505 properly and provided a fix. http://curl.haxx.se/bug/view.cgi?id=2843008
507 - Eric Wong introduced support for the new option -T. (dot) that makes curl
508 read stdin in a non-blocking fashion. This also brings back -T- (minus) to
509 the previous blocking behavior since it could break stuff for people at
512 Michal Marek (21 Aug 2009)
513 - With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like
514 ftp://example.com;type=i if the user specified ftp://example.com without the
517 Daniel Stenberg (21 Aug 2009)
518 - Andre Guibert de Bruet pointed out a missing return code check for a
519 strdup() that could lead to segfault if it returned NULL. I extended his
520 suggest patch to now have Curl_retry_request() return a regular return code
521 and better check that.
523 - Lots of good work by Krister Johansen, mostly related to pipelining:
525 Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
526 Fix data corruption issue with re-connected transfers
527 Fix use after free if we're completed but easy_conn not NULL
529 Kamil Dudka (13 Aug 2009)
530 - Changed NSS code to not ignore the value of ssl.verifyhost and produce more
531 verbose error messages. Originally reported at:
532 https://bugzilla.redhat.com/show_bug.cgi?id=516056
534 Daniel Stenberg (12 Aug 2009)
535 - Karl Moerder fixed the Makefile.vc* makefiles to include the new file
536 nonblock.c so that they work fine again
538 - I expanded test 517 with a bunch of more dates that originate from the
539 Chrome browser test suite. It turns out most of them get parsed the same
542 Version 7.19.6 (12 August 2009)
544 Daniel Stenberg (12 Aug 2009)
545 - Carsten Lange reported a bug and provided a patch for TFTP upload and the
546 sending of the TSIZE option. I don't like fixing bugs just hours before
547 a release, but since it was broken and the patch fixes this for him I decided
550 Daniel Stenberg (11 Aug 2009)
551 - Peter Sylvester made the HTTPS test server use specific certificates for
552 each test, so that the test suite can now be used to actually test the
553 verification of cert names etc. This made an error show up in the OpenSSL-
554 specific code where it would attempt to match the CN field even if a
555 subjectAltName exists that doesn't match. This is now fixed and verified
558 - Benbuck Nason posted the bug report #2835196
559 (http://curl.haxx.se/bug/view.cgi?id=2835196), fixing a few compiler
560 warnings when mixing ints and bools.
562 Daniel Fandrich (10 Aug 2009)
563 - Fixed a memory leak in the FTP code and an off-by-one heap buffer overflow.
565 Daniel Fandrich (9 Aug 2009)
566 - Fixed some memory leaks in the command-line tool that caused most of the
567 torture tests to fail.
569 Daniel Stenberg (2 Aug 2009)
570 - Curt Bogmine reported a problem with SNI enabled on a particular server. We
571 should introduce an option to disable SNI, but as we're in feature freeze
572 now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
573 shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
574 Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
575 option for SNI, or are we simply not using it?
577 Daniel Stenberg (1 Aug 2009)
578 - Scott Cantor posted the bug report #2829955
579 (http://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert
580 verification flaw found and exploited by Moxie Marlinspike. The presentation
581 he did at Black Hat is available here:
582 https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike
584 Apparently at least one CA allowed a subjectAltName or CN that contain a
585 zero byte, and thus clients that assumed they would never have zero bytes
586 were exploited to OK a certificate that didn't actually match the site. Like
587 if the name in the cert was "example.com\0theatualsite.com", libcurl would
588 happily verify that cert for example.com.
590 libcurl now better uses the length of the extracted name, not using the zero
591 termination for getting the string length.
593 This fixing only made and needed in OpenSSL interfacing code.
595 - Tanguy Fautre pointed out that OpenSSL's function RAND_screen() (present
596 only in some OpenSSL installs - like on Windows) isn't thread-safe and we
597 agreed that moving it to the global_init() function is a decent way to deal
600 - Alexander Beedie provided the patch for a noproxy problem: If I have set
601 CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually
602 could still end up using a proxy if a proxy environment variable was set.
604 Daniel Stenberg (27 Jul 2009)
605 - All the quote options (CURLOPT_QUOTE, CURLOPT_POSTQUOTE and
606 CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
607 send when using FTP, as a sign that libcurl shall simply ignore the response
608 from the server instead of treating it as an error. Not treating a 400+ FTP
609 response code as an error means that failed commands will not abort the
610 chain of commands, nor will they cause the connection to get disconnected.
612 Daniel Stenberg (26 Jul 2009)
613 - Johan van Selst posted bug report #2825989
614 (http://curl.haxx.se/bug/view.cgi?id=2825989) pointing out that
615 OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm, and
616 provided the solution too: to use OpenSSL_add_all_algorithms() in addition
617 to the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
620 Daniel Stenberg (23 Jul 2009)
621 - Added CURLOPT_SSH_KNOWNHOSTS, CURLOPT_SSH_KEYFUNCTION, CURLOPT_SSH_KEYDATA.
622 They introduce known_host support for SSH keys to libcurl. See docs for
623 details. Note that this feature depends on a new enough libssh2 version, to
624 be supported in libssh2 1.2 and later (or current git repo at this time).
626 Michal Marek (22 Jul 2009)
627 - David Binderman found a memory and fd leak in lib/gtls.c:load_file()
628 (https://bugzilla.novell.com/523919). When looking at the code, I found that
629 also the ptr pointer can leak.
631 Kamil Dudka (20 Jul 2009)
632 - Claes Jakobsson improved the support for client certificates handling in
633 NSS-powered libcurl. Now the client certificates can be selected
634 automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
635 slots is no more performed. It used to cause problems with HW tokens.
637 - Fixed reference counting for NSS client certificates. Now the PEM reader
638 module should be always properly unloaded on Curl_nss_cleanup(). If the
639 unload fails though, libcurl will try to reuse the already loaded instance.
641 Daniel Fandrich (15 Jul 2009)
642 - Added nonblock.c to the non-automake makefiles (note that the dependencies
643 in the Watcom makefiles aren't quite correct).
645 Michal Marek (15 Jul 2009)
646 - Changed the description of CURLINFO_OS_ERRNO to make it clear that the
647 errno is not reset on success.
649 Guenter Knauf (14 Jul 2009)
650 - renamed generated config.h to curl_config.h to avoid any future clashes
651 with config.h from other projects.
653 Daniel Stenberg (9 Jul 2009)
654 - Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses for
655 setting a file descriptor non-blocking. Used by the functionality Eric
656 himself brough on June 15th.
658 Daniel Stenberg (8 Jul 2009)
659 - Constantine Sapuntzakis posted bug report #2813123
660 (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
663 Url A is accessed using auth. Url A redirects to Url B (on a different
664 server0. Url B reuses a persistent connection. Url B has auth, even though
665 it's on a different server.
667 Note: if Url B does not reuse a persistent connection, auth is not sent.
671 data->state.first_host is not initialized becuase Curl_http_connect is not
672 called when a connection is reused.
676 move initialization of data->state.first_host to Curl_http. No code before
677 Curl_http uses data->state.first_host anyway.
679 Guenter Knauf (4 Jul 2009)
680 - Markus Koetter provided a patch to avoid getnameinfo() usage which broke a
681 couple of both IPv4 and IPv6 autobuilds.
683 Daniel Stenberg (29 Jun 2009)
684 - Markus Koetter made CURLOPT_FTPPORT (and curl's -P/--ftpport) support a port
685 range if given colon-separated after the host name/address part. Like
686 "192.168.0.1:2000-10000"
688 - Modified the separators used for CURLOPT_CERTINFO in multi-part outputs. I
689 don't know how they got wrong in the first place, but using this output
690 format makes it possible to quite easily separate the string into an array
693 Daniel Fandrich (16 June 2009)
694 - Added a few more compiler warning options for gcc.
696 Daniel Stenberg (16 Jun 2009)
697 - Reuven Wachtfogel made curl -o - properly produce a binary output on windows
698 (no newline translations). Use -B/--use-ascii if you rather get the ascii
701 Michal Marek (16 Jun 2009)
702 - When doing non-anonymous ftp via http proxies and the password is not
703 provided in the url, add it there (squid needs this).
705 Daniel Stenberg (15 Jun 2009)
708 This allows curl(1) to be used as a client-side tunnel for arbitrary stream
709 protocols by abusing chunked transfer encoding in both the HTTP request and
710 HTTP response. This requires server support for sending a response while a
711 request is still being read, of course.
713 If attempting to read from stdin returns EAGAIN, then we pause our sender.
714 This leaves curl to attempt to read from the socket while reading from stdin
715 (and thus sending) is paused.
717 This change was needed to allow successfully tunneling the git protocol over
718 HTTP (--no-buffer is needed, as well).
720 Patrick Monnerat (15 Jun 2009)
721 - Replaced use of standard C library rand()/srand() by our own pseudo-random
724 Yang Tse (11 Jun 2009)
725 - I adapted testcurl script to allow building test harness programs when
726 cross-compiling for a *-*-mingw* host.
728 Daniel Stenberg (10 Jun 2009)
729 - Fabian Keil ran clang on the (lib)curl code, found a bunch of warnings and
730 contributed a range of patches to fix them.
732 Yang Tse (10 Jun 2009)
733 - I introduced configure script option --enable-curldebug which now allows
734 the decoupled enabling or disabling of the curl debug memory tracking
735 feature from the --enable-debug option which no longer controls this.
737 curl --version will list 'Debug' feature for debug enabled builds, and
738 will list 'TrackMemory' feature for curl debug memory tracking capable
739 builds. These features are independent and can be controlled when running
740 the configure script. When --enable-debug is given both features will be
741 enabled, unless some restriction prevents memory tracking from being used.
743 Internally, definition of preprocessor symbol DEBUGBUILD restricts code
744 which is only compiled for debug enabled builds. And symbol CURLDEBUG is
745 used to differentiate code which is _only_ used for memory tracking.
747 Yang Tse (9 Jun 2009)
748 - Daniel Steinberg pointed out that Curl_FormInit() in formdata.c was not
749 initializing the fread callback pointer and this triggered a compiler
750 warning, also provided a friendly suggestion on how to fix it.
752 Daniel Stenberg (8 Jun 2009)
753 - Claes Jakobsson provided a patch for libcurl-NSS that fixed a bad refcount
754 issue with client certs that caused issues like segfaults.
755 http://curl.haxx.se/mail/lib-2009-05/0316.html
757 - Triggered by bug report #2798852 and the patch in there, I fixed configure
758 to detect gnutls build options with pkg-config only and not libgnutls-config
759 anymore since GnuTLS has stopped distributing that tool. If an explicit path
760 is given to configure, we will instead guess on how to link and use that
761 lib. I did not use the patch from the bug report.
763 Yang Tse (8 Jun 2009)
764 - Igor Novoseltsev adjusted Makefile.vxworks to get sources and headers
765 included from Makefile.inc, and provided docs\INSTALL VxWorks section.
767 - I removed buildconf.bat from release and daily snapshot archives. This
768 file is only for CVS tree checkout builds.
770 Daniel Stenberg (8 Jun 2009)
771 - Eric Wong fixed --no-buffer to actually switch off output buffering. Been
774 Bill Hoffman (6 Jun 2009)
775 - Added some cmake docs and fixed socklen_t in the build.
777 Yang Tse (5 Jun 2009)
778 - John E. Malmberg provided VMS specific patch: "This fixes an existing bug
779 in urlglob.c where it was not converting the Curl Unix exit code to a VMS
780 DCL compatible exit code. This fix required the enhancement described next.
781 This also adds an enhancement to main.c so that when curl is run under a
782 Unix shell like Bash on VMS, it will return the standard Unix exit codes
783 and messages." And another patch for docs/examples.
785 I introduced os-specific.c and os-specific.h for use in curl tool code
786 and adjusted John E. Malmberg's patch placement to use these new files
787 as an effort to prevent main.c from growing ad infinitum. Code already
788 existing in main.c which is OS specific should be moved into these files.
790 Daniel Stenberg (4 June 2009)
791 - Setting the Content-Length: header from your app when you do a POST or PUT
792 is almost always a VERY BAD IDEA. Yet there are still apps out there doing
793 this, and now recently it triggered a bug/side-effect in libcurl as when
794 libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
795 knows it will just get a 401/407 back. If the app then replaced the
796 Content-Length header, it caused the server to wait for input that libcurl
797 wouldn't send. Aaron Oneal reported this problem in bug report #2799008
798 (http://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix.
800 Yang Tse (4 Jun 2009)
801 - Igor Novoseltsev provided patches and information, that after some
802 adjustments to better fit curl's way of doing things, have resulted
803 in the posibility of building libcurl for VxWorks.
805 Daniel Fandrich (2 June 2009)
806 - Checked in a Google Android make file. To use it, you must first
807 create a config.h file by running configure in the Android environment,
808 which doesn't seem to be easy to do. If no easy way can be found, a
809 static config-android.h may need to be created and checked in to the
812 Daniel Stenberg (1 June 2009)
813 - Claes Jakobsson fixed the configure script to better find and use NSS
816 Yang Tse (1 Jun 2009)
817 - John E. Malmberg provided a VMS specific clean-up for curl.h, and pointed
818 out that the configure script was failing to detect the timeval struct on
819 VMS when building with _XOPEN_SOURCE_EXTENDED undefined due to definition
820 taking place in socket.h instead of time.h. I have adjusted configure
821 script to also include this header when checking struct timeval.
823 Daniel Stenberg (27 May 2009)
824 - Frank McGeough provided a small OpenSSL #include fix to make libcurl compile
825 fine with Nokia 5th edition 1.0 SDK for Symbian.
827 - Andre Guibert de Bruet found a call to a OpenSSL function that didn't check
828 for a failure properly.
830 - Mike Crowe pointed out that setting CURLOPT_USERPWD to NULL used to clear
831 the auth credentials back in 7.19.0 and earlier while now you have to set ""
832 to get the same effect. His patch brings back the ability to use NULL.
834 - Claes Jakobsson fixed libcurl-NSS to build fine even without the
835 PK11_CreateGenericObject() function.
837 Daniel Stenberg (25 May 2009)
838 - bug report #2796358 (http://curl.haxx.se/bug/view.cgi?id=2796358) pointed
839 out that the cookie parser would leak memory when it parses cookies that are
840 received with domain, path etc set multiple times in the same header. While
841 such a cookie is questionable, they occur in the wild and libcurl no longer
842 leaks memory for them. I added such a header to test case 8.
844 Daniel Fandrich (22 May 2009)
845 - Removed some obsolete digest code that caused a valgrind error in test 551.
847 Daniel Fandrich (20 May 2009)
848 - Added "non-existing host" test keywords to make it easy to skip those
849 tests on machines that have broken DNS configurations (such as
850 those configured to use OpenDNS).
852 Daniel Stenberg (19 May 2009)
853 - Kamil Dudka brought the patch from the Redhat bug entry
854 https://bugzilla.redhat.com/show_bug.cgi?id=427966 which was libcurl closing
855 a bad file descriptor when closing down the FTP data connection. Caolan
856 McNamara seems to be the original author of it.
858 Version 7.19.5 (18 May 2009)
860 Daniel Stenberg (17 May 2009)
861 - James Bursa posted a patch to the mailing list that fixed a problem with
862 no_proxy which made it not skip the proxy if the URL entered contained a
863 user name. I added test case 1101 to verify.
865 Daniel Stenberg (11 May 2009)
866 - Balint Szilakszi reported a memory leak when libcurl did gzip decompression
867 of streams that had some parts (legitimately) missing. We now provide and use
868 a proper cleanup function for the content encoding submodule.
869 http://curl.haxx.se/mail/lib-2009-05/0092.html
871 - Kamil Dudka provided a fix for libcurl-NSS reported by Michael Cronenworth
872 at https://bugzilla.redhat.com/show_bug.cgi?id=453612#c12
874 If an incorrect password is given while loading a private key, libcurl ends
875 up in an infinite loop consuming memory. The bug is critical.
877 - I fixed the problem with doing NTLM, POST and then following a 302 redirect,
878 as reported by Ebenezer Ikonne (on curl-users) and Laurent Rabret (on
879 curl-library). The transfer was mistakenly marked to get more data to send
880 but since it didn't actually have that, it just hung there...
882 Daniel Stenberg (10 May 2009)
883 - Andre Guibert de Bruet correctly pointed out an over-alloc with one wasted
884 byte in the digest code.
886 Yang Tse (9 May 2009)
887 - Removed DOS and TPF package's subdirectory Makefile.am, it was only used
888 to include some files in the distribution tarball serving no other purpose.
889 Files from the DOS and TPF subdirectories are now included in the EXTRA_DIST
890 of the Makefile in the parent subdirectory.
892 Yang Tse (8 May 2009)
893 - Changed host name literal in several tests to one under the haxx.se domain.
895 - Renamed vc6 workspace and project files to avoid filename clash when used
896 for conversion to later VS versions.
898 Daniel Stenberg (8 May 2009)
899 - Constantine Sapuntzakis fixed bug report #2784055
900 (http://curl.haxx.se/bug/view.cgi?id=2784055) identifying a problem to
901 connect to SOCKS proxies when using the multi interface. It turned out to
902 almost not work at all previously. We need to wait for the TCP connect to
903 be properly verified before doing the SOCKS magic.
905 There's still a flaw in the FTP code for this.
907 Daniel Stenberg (7 May 2009)
908 - Made the SO_SNDBUF setting for the data connection socket for ftp uploads as
909 well. See change 28 Apr 2009.
911 Yang Tse (7 May 2009)
912 - Fixed an issue affecting FTP transfers, introduced with the transfer.c
913 patch committed May 4.
915 Daniel Stenberg (7 May 2009)
916 - Man page *roff problems fixed thanks to input from Colin Watson. Problems
917 reported in the Debian package.
919 - Vijay G filed bug report #2723236
920 (http://curl.haxx.se/bug/view.cgi?id=2723236) identifying a problem with
921 libcurl's TFTP code and its lack of dealing with the OACK packet.
923 Yang Tse (5 May 2009)
924 - Fixed the --ftp-port address of test #251 to the CLIENTIP address, and
925 reverted the change affecting test suite harness committed 4 May.
927 Daniel Stenberg (5 May 2009)
928 - Inspired by Michael Smith's session id fix for OpenSSL, I did the
929 corresponding fix in the GnuTLS code: make sure to store the new session id
930 in case the previous re-used one is rejected.
932 Daniel Stenberg (4 May 2009)
933 - Michael Smith posted bug report #2786255
934 (http://curl.haxx.se/bug/view.cgi?id=2786255) with a patch, identifying how
935 libcurl did not deal with SSL session ids properly if the server rejected a
936 re-use of one. Starting now, it will forget the rejected one and remember
937 the new. This change was for OpenSSL only, it is likely that other SSL lib
938 code needs similar fixes.
940 Yang Tse (4 May 2009)
941 - Applied David McCreedy's "transfer.c fixes for CURL_DO_LINEEND_CONV and
942 non-ASCII platform HTTP requests" patch addressing two HTTP PUT problems:
943 1) On non-ASCII platforms not all of the protocol portions of the PUT are
944 being translated to ASCII. 2) On all platforms the line endings of part of
945 the protocol portions are mangled from CRLF to CRCRLF if data->set.crlf or
946 data->set.prefer_ascii are set (depending on CURL_DO_LINEEND_CONV).
948 - Applied David McCreedy's patch to fix test suite harness to allow test FTP
949 server and client on different machines, providing FTP client address when
950 running the FTP test server.
952 Daniel Fandrich (3 May 2009)
953 - Added and disabled test case 563 which shows KNOWN_BUGS #59. The bug
954 report failed to mention that a proxy must be used to reproduce it.
956 Yang Tse (2 May 2009)
957 - Use a build-time configured curl_socklen_t data type instead of socklen_t.
959 Yang Tse (1 May 2009)
960 - Applied David McCreedy's patches "TPF-platform specific changes to various
961 files" and "http.c fix to Curl_proxyCONNECT for non-ASCII platforms", the
962 former with minor edits.
964 Daniel Stenberg (30 Apr 2009)
965 - I was going to fix issue #59 in KNOWN_BUGS
967 If the CURLOPT_PORT option is used on an FTP URL like
968 "ftp://example.com/file;type=A" the ";type=A" is stripped off.
970 I added test case 562 to verify, only to find out that I couldn't repeat
971 this bug so I hereby consider it not a bug anymore!
973 Daniel Stenberg (29 Apr 2009)
974 - Based on bug report #2723219 (http://curl.haxx.se/bug/view.cgi?id=2723219)
975 I've now made TFTP "connections" not being kept for re-use within libcurl.
976 TFTP is UDP-based so the benefit was really low (if even existing) to begin
977 with so instead of tracking down to fix this problem we instead removed the
978 re-use. I also enabled test case 1099 that I wrote a few days ago to verify
979 that this change fixes the reported problem.
981 Daniel Stenberg (28 Apr 2009)
982 - Constantine Sapuntzakis filed bug report #2783090
983 (http://curl.haxx.se/bug/view.cgi?id=2783090) pointing out that on windows
984 we need to grow the SO_SNDBUF buffer somewhat to get really good upload
985 speeds. http://support.microsoft.com/kb/823764 has the details. Friends
986 confirmed that simply adding 32 to CURL_MAX_WRITE_SIZE is enough.
988 - Bug report #2709004 (http://curl.haxx.se/bug/view.cgi?id=2709004) by Tim
989 Chen pointed out how curl couldn't upload with resume when reading from a
992 This ended up with the introduction of a new return code for the
993 CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
994 that libcurl may try to resolve the situation anyway. In our case this means
995 libcurl will attempt to instead read that much data from the stream instead
996 of seeking and that way curl can now upload with resume when data is read
999 Daniel Stenberg (26 Apr 2009)
1000 - Bug report #2779733 (http://curl.haxx.se/bug/view.cgi?id=2779733) by Sven
1001 Wegener pointed out that CURLINFO_APPCONNECT_TIME didn't work with the multi
1002 interface and provided a patch that fixed the problem!
1004 Daniel Stenberg (24 Apr 2009)
1005 - Kamil Dudka fixed another NSS-related leak when client certs were used.
1007 - Bug report #2779245 (http://curl.haxx.se/bug/view.cgi?id=2779245) by Rainer
1008 Koenig pointed out that the man page didn't tell that the *_proxy
1009 environment variables can be specified lower case or UPPER CASE and the
1010 lower case takes precedence,
1012 Daniel Fandrich (21 Apr 2009)
1013 - Added new libcurl source files to Amiga, RiscOS and VC6 build files.
1015 Yang Tse (21 Apr 2009)
1016 - Moved potential inclusion of system's malloc.h and memory.h header files to
1017 setup_once.h. Inclusion of each header file is based on the definition of
1018 NEED_MALLOC_H and NEED_MEMORY_H respectively.
1020 Renamed libcurl's memory.h to curl_memory.h

1023 - Leanic Lefever reported a crash and did some detailed research on why and
1024 how it occurs (http://curl.haxx.se/mail/lib-2009-04/0289.html). The
1025 conclusion was that if an error is detected and Curl_done() is called for
1026 the connection, ftp_done() could at times return another error code that
1027 then would take precedence and that new code confused existing logic that
1028 works for the first error code (CURLE_SEND_ERROR) only.
1030 - Gisle Vanem noticed that --libtool would produce bogus strings at times for
1031 OBJECTPOINT options. Now we've introduced a new function - my_setopt_str -
1032 within the app for setting plain string options to avoid the risk of this
1035 Daniel Stenberg (17 Apr 2009)
1036 - Pramod Sharma reported and tracked down a bug when doing FTP over a HTTP
1037 proxy. libcurl would then wrongly close the connection after each
1038 request. In his case it had the weird side-effect that it killed NTLM auth
1039 for the proxy causing an inifinite loop!
1041 I added test case 1098 to verify this fix. The test case does however not
1042 properly verify that the transfers are done persistently - as I couldn't
1043 think of a clever way to achieve it right now - but you need to read the
1044 stderr output after a test run to see that it truly did the right thing.
1046 Daniel Stenberg (13 Apr 2009)
1047 - bug report #2727981 (http://curl.haxx.se/bug/view.cgi?id=2727981) by Martin
1048 Storsjö pointed out how setting CURLOPT_NOBODY to 0 could be downright
1049 confusing as it set the method to either GET or HEAD. The example he showed
1052 curl_easy_setopt(curl, CURLOPT_PUT, 1);
1053 curl_easy_setopt(curl, CURLOPT_NOBODY, 0);
1055 The new way doesn't alter the method until the request is about to start. If
1056 CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is
1057 0 and the request happens to have been set to HEAD, it will then instead be
1058 set to GET. I believe this will be less surprising to users, and hopefully
1059 not hit any existing users badly.
1061 - Toshio Kuratomi reported a memory leak problem with libcurl+NSS that turned
1062 out to be leaking cacerts. Kamil Dudka helped me complete the fix. The issue
1063 is found in Redhat's bug tracker:
1064 https://bugzilla.redhat.com/show_bug.cgi?id=453612
1066 There are still memory leaks present, but they seem to have other reasons.
1068 Daniel Fandrich (11 Apr 2009)
1069 - Added new libcurl source files to Symbian OS build files.
1070 - Improved Symbian support for SSL.
1072 Yang Tse (10 Apr 2009)
1073 - Daniel Johnson improved the MacOSX-Framework shell script to now perform all
1074 the steps required to build a Mac OS X four way fat ppc/i386/ppc64/x86_64
1075 libcurl.framework. Four way fat framework requires OS X 10.5 SDK or later.
1077 Yang Tse (8 Apr 2009)
1078 - Removed Sun compilers preprocessor block from curlbuild.h.dist, this also
1079 removes it from the curlbuild.h file originally distributed by the cURL
1080 project as this file is intended for systems not capable of running the
1081 configure script. For those who have been building curl out of the source
1082 code curl distribution tarball provided by curl.haxx.se the change implies
1083 nothing. Previous change in this area committed 2 Apr becomes irrelevant.
1085 Daniel Stenberg (6 Apr 2009)
1086 - I clarified in the docs that CURLOPT_SEEKFUNCTION should return 0 on success
1087 and 1 on fatal errors. Previously it only mentioned non-zero on fatal
1088 errors. This is a slight change in meaning, but it follows what we've done
1089 elsewhere before and it opens up for LOTS of more useful return codes
1090 whenever we can think of them...
1092 Yang Tse (2 Apr 2009)
1093 - Fix curl_off_t definition for builds done using Sun compilers and a
1094 non-configured libcurl. In this case curl_off_t data type was gated
1095 to the off_t data type which depends on the _FILE_OFFSET_BITS. This
1096 configuration is exactly the unwanted configuration for our curl_off_t
1097 data type which must not depend on such setting. This breaks ABI for
1098 libcurl libraries built with Sun compilers which were built without
1099 having run the configure script with _FILE_OFFSET_BITS different than
1100 64 and using the ILP32 data model.
1102 Daniel Stenberg (1 Apr 2009)
1103 - Andre Guibert de Bruet fixed a NULL pointer use in an infof() call if a
1104 strdup() call failed.
1106 Daniel Fandrich (31 Mar 2009)
1107 - Properly return an error code in curl_easy_recv (reported by Jim Freeman).
1109 Daniel Stenberg (18 Mar 2009)
1110 - Kamil Dudka brought a patch that enables 6 additional crypto algorithms when
1111 NSS is used. These ciphers were added in NSS 3.4 and require to be enabled
1114 Daniel Stenberg (13 Mar 2009)
1115 - Use libssh2_version() to present the libssh2 version in case the libssh2
1116 library is found to support it.
1118 Yang Tse (12 Mar 2009)
1119 - Added missing Curl_read() return code checking in TELNET transfers.
1121 - Pierre Brico found and fixed TELNET transfers not being aborted upon
1122 a write callback failure.
1124 Daniel Stenberg (11 Mar 2009)
1125 - Kamil Dudka made the curl tool properly call curl_global_init() before any
1126 other libcurl function.
1128 Yang Tse (11 Mar 2009)
1129 - Added missing TELNET timeout support for Windows builds. This issue was
1130 reported by Pierre Brico.
1132 Daniel Stenberg (9 Mar 2009)
1133 - Frank Hempel found out a bug and provided the fix:
1135 curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE
1136 option. It only enabled the cookie engine in the destination handle if
1137 data->cookies is not NULL (where data is the source handle). In case of a
1138 newly initialized handle which just had the cookie support enabled by a
1139 curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was
1140 still NULL because the setopt-call only appends the value to
1141 data->change.cookielist, hence duplicating this handle would not have the
1142 cookie engine switched on.
1144 We also concluded that the slist-functionality would be suitable for being
1145 put in its own module rather than simply hanging out in lib/sendf.c so I
1146 created lib/slist.[ch] for them.
1148 - Andreas Farber made the 'buildconf' script check for the presence of m4
1149 scripts to make it detect a bad checkout earlier. People with older
1150 checkouts who don't do cvs update with the -d option won't get the new dirs
1151 and then will get funny outputs that can be a bit hard to understand and
1154 Daniel Stenberg (8 Mar 2009)
1155 - Andre Guibert de Bruet found and fixed a code segment in ssluse.c where the
1156 allocation of the memory BIO was not being properly checked.
1158 - Andre Guibert de Bruet fixed the gnutls-using code: There are a few places
1159 in the gnutls code where we were checking for negative values for errors,
1160 when the man pages state that GNUTLS_E_SUCCESS is returned on success and
1161 other values indicate error conditions.
1163 - Bill Egert pointed out (http://curl.haxx.se/bug/view.cgi?id=2671602) that
1164 curl didn't use sprintf() in a way that is documented to work in POSIX but
1165 since we use our own printf() code (from libcurl) that shouldn't be a
1166 problem. Nonetheless I modified the code to not rely on such particular
1167 features and to not cause further raised eyebrowse with no good reason.
1169 Daniel Fandrich (5 Mar 2009)
1170 - Expanded the security section of the libcurl-tutorial man page to cover
1171 more issues for authors to consider when writing robust libcurl-using
1174 Yang Tse (5 Mar 2009)
1175 - Fixed NTLM authentication memory leak on SSPI enabled Windows builds. This
1176 issue was noticed by Chris Deidun.
1178 Daniel Fandrich (4 Mar 2009)
1179 - Fixed a problem with m4 quoting in the OpenSSL configure check reported
1182 Daniel Stenberg (3 Mar 2009)
1183 - David James brought a patch that make libcurl close (all) dead connections
1184 whenever you attempt to open a new connection.
1186 1. After cleaning up a dead connection, "continue" instead of
1187 returning FALSE. This ensures that we clean up all dead connections,
1188 rather than just cleaning up the first dead connection.
1189 2. Move up the cleanup for dead connections so that it occurs for
1190 all connections, rather than just the connections which have the same
1191 preferences as our current new connection.
1193 Version 7.19.4 (3 March 2009)
1195 Daniel Stenberg (3 Mar 2009)
1196 - David Kierznowski notified us about a security flaw
1197 (http://curl.haxx.se/docs/adv_20090303.html also known as CVE-2009-0037) in
1198 which previous libcurl versions (by design) can be tricked to access an
1199 arbitrary local/different file instead of a remote one when
1200 CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
1201 together this the addition of two new setopt options for controlling this
1204 o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
1205 follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
1206 excludes the FILE and SCP protocols and thus you nee to explicitly allow
1207 them in your app if you really want that behavior.
1209 o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
1210 using the primary URL option. This is useful if you want to allow a user or
1211 other outsiders control what URL to pass to libcurl and yet not allow all
1212 protocols libcurl may have been built to support.
1214 Daniel Stenberg (27 Feb 2009)
1215 - Senthil Raja Velu reported a problem when CURLOPT_INTERFACE and
1216 CURLOPT_LOCALPORT were used together (the local port bind failed), and
1217 Markus Koetter provided the fix!
1219 Daniel Stenberg (25 Feb 2009)
1220 - As Daniel Fandrich figured out, we must do the GnuTLS initing in the
1221 curl_global_init() function to properly maintain the performing functions
1222 thread-safe. We've previously (28 April 2007) moved the init to a later time
1223 just to avoid it to fail very early when libgcrypt dislikes the situation,
1224 but that move was bad and the fix should rather be in libgcrypt or
1227 Daniel Stenberg (24 Feb 2009)
1228 - Brian J. Murrell found out that Negotiate proxy authentication didn't work.
1229 It happened because the code used the struct for server-based auth all the
1230 time for both proxy and server auth which of course was wrong.
1232 Daniel Stenberg (23 Feb 2009)
1233 - After a bug reported by James Cheng I've made curl_easy_getinfo() for
1234 CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return
1235 -1 if the sizes aren't know. Previously these returned 0, make it impossible
1236 to detect the difference between actually zero and unknown.
1238 Yang Tse (23 Feb 2009)
1239 - Daniel Johnson provided a shell script that will perform all the steps needed
1240 to build a Mac OS X fat ppc/i386 or ppc64/x86_64 libcurl.framework
1242 Daniel Stenberg (23 Feb 2009)
1243 - I renamed everything in the windows builds files that used the name 'curllib'
1244 to the proper 'libcurl' as clearly this caused confusion.
1246 Yang Tse (20 Feb 2009)
1247 - Do not halt compilation when using VS2008 to build a Windows 2000 target.
1249 Daniel Stenberg (20 Feb 2009)
1250 - Linus Nielsen Feltzing reported and helped me repeat and fix a problem with
1251 FTP with the multi interface: when a transfer fails, like when aborted by a
1252 write callback, the control connection was wrongly closed and thus not
1255 This change is also an attempt to cleanup the code somewhat in this area, as
1256 now the FTP code attempts to keep (better) track on pending responses
1257 necessary to get read in ftp_done().
1259 Daniel Stenberg (19 Feb 2009)
1260 - Patrik Thunstrom reported a problem and helped me repeat it. It turned out
1261 libcurl did a superfluous 1000ms wait when doing SFTP downloads!
1263 We read data with libssh2 while doing the "DO" operation for SFTP and then
1264 when we were about to start getting data for the actual file part, the
1265 "TRANSFER" part, we waited for socket action (in 1000ms) before doing a
1266 libssh2-read. But in this case libssh2 had already read and buffered the
1267 data so we ended up always just waiting 1000ms before we get working on the
1270 Patrick Monnerat (18 Feb 2009)
1271 - FTP downloads (i.e.: RETR) ending with code 550 now return error
1272 CURLE_REMOTE_FILE_NOT_FOUND instead of CURLE_FTP_COULDNT_RETR_FILE.
1274 Daniel Stenberg (17 Feb 2009)
1275 - Kamil Dudka made NSS-powered builds compile and run again!
1277 - A second follow-up change by Andre Guibert de Bruet to fix a related memory
1278 leak like that fixed on the 14th. When zlib returns failure, we need to
1279 cleanup properly before returning error.
1281 - CURLOPT_FTP_CREATE_MISSING_DIRS can now be set to 2 in addition to 1 for
1282 plain FTP connections, and it will then allow MKD to fail once and retry the
1283 CWD afterwards. This is especially useful if you're doing many simultanoes
1284 connections against the same server and they all have this option enabled,
1285 as then CWD may first fail but then another connection does MKD before this
1286 connection and thus MKD fails but trying CWD works! The numbers can
1287 (should?) now be set with the convenience enums now called
1288 CURLFTP_CREATE_DIR and CURLFTP_CREATE_DIR_RETRY.
1290 Tests has proven that if you're making an application that uploads a set of
1291 files to an ftp server, you will get a noticable gain in speed if you're
1292 using multiple connections and this option will be then be very useful.
1294 Daniel Stenberg (14 Feb 2009)
1295 - Andre Guibert de Bruet found and fixed a memory leak in the content encoding
1296 code, which could happen on libz errors.
1298 Daniel Fandrich (12 Feb 2009)
1299 - Added support for Digest and NTLM authentication using GnuTLS.
1301 Daniel Stenberg (11 Feb 2009)
1302 - CURLINFO_CONDITION_UNMET was added to allow an application to get to know if
1303 the condition in the previous request was unmet. This is typically a time
1304 condition set with CURLOPT_TIMECONDITION and was previously not possible to
1305 reliably figure out. From bug report #2565128
1306 (http://curl.haxx.se/bug/view.cgi?id=2565128) filed by Jocelyn Jaubert.
1308 Daniel Fandrich (4 Feb 2009)
1309 - Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS
1310 (respectively) when --with-ssl=/usr is used (patch based on FreeBSD).
1312 - Added an explicit buffer limit check in msdosify() (patch based on FreeBSD).
1313 This couldn't ever overflow in curl, but might if the code were used
1314 elsewhere or under different conditions.
1316 Daniel Stenberg (3 Feb 2009)
1317 - Hidemoto Nakada provided a small fix that makes it possible to get the
1318 CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with
1319 CURLOPT_NOBODY set true.
1321 Daniel Stenberg (2 Feb 2009)
1322 - Patrick Scott found a rather large memory leak when using the multi
1323 interface and setting CURLMOPT_MAXCONNECTS to something less than the number
1324 of handles you add to the multi handle. All the connections that didn't fit
1325 in the cache would not be properly disconnected nor freed!
1327 - Craig A West brought us: libcurl now defaults to do CONNECT with HTTP
1328 version 1.1 instead of 1.0 like before. This change also introduces the new
1329 proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
1330 switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
1331 option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.
1333 I updated all test cases cases that use CONNECT and I tried to do some using
1334 --proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.
1336 Daniel Stenberg (31 Jan 2009)
1337 - When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
1338 enabled, we can now take advantage of its brand new AF_UNSPEC support in
1339 ares_gethostbyname(). This makes test case 241 finally run fine for me with
1340 this setup since it now parses the "::1 ip6-localhost" line fine in my
1343 Daniel Stenberg (30 Jan 2009)
1344 - Scott Cantor filed bug report #2550061
1345 (http://curl.haxx.se/bug/view.cgi?id=2550061) mentioning that I failed to
1346 properly make sure that the VC9 makefiles got included in the latest
1347 release. I've now fixed the release script and verified it so next release
1348 will hopefully include them properly!
1350 Daniel Fandrich (30 Jan 2009)
1351 - Fixed --disable-proxy for FTP and SOCKS. Thanks to Daniel Egger for
1354 Yang Tse (29 Jan 2009)
1355 - Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
1356 Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
1357 named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
1358 Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
1359 SSPI library using it now in the same way as it was done in http_ntlm.c.
1361 Daniel Stenberg (28 Jan 2009)
1362 - Markus Moeller introduced two new options to libcurl:
1363 CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl
1364 to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
1365 options called --socks5-gssapi-service and --socks5-gssapi-nec to enable
1368 Daniel Stenberg (26 Jan 2009)
1369 - Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app
1370 to set desired block size to use for TFTP transfers instead of the default
1373 - The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
1374 disable "rfc4507bis session ticket support". rfc4507bis was later turned
1375 into the proper RFC5077 it seems: http://tools.ietf.org/html/rfc5077
1377 The enabled extension concerns the session management. I wonder how often
1378 libcurl stops a connection and then resumes a TLS session. also, sending the
1379 session data is some overhead. .I suggest that you just use your proposed
1380 patch (which explicitly disables TICKET).
1382 If someone writes an application with libcurl and openssl who wants to
1383 enable the feature, one can do this in the SSL callback.
1385 Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
1386 on the proper action.
1388 - Alexey Borzov filed bug report #2535504
1389 (http://curl.haxx.se/bug/view.cgi?id=2535504) pointing out that realms with
1390 quoted quotation marks in HTTP Digest headers didn't work. I've now added
1391 test case 1095 that verifies my fix.
1393 - Craig A West brought CURLOPT_NOPROXY and the corresponding --noproxy option.
1394 They basically offer the same thing the NO_PROXY environment variable only
1395 offered previously: list a set of host names that shall not use the proxy
1396 even if one is specified.
1398 Daniel Fandrich (20 Jan 2009)
1399 - Call setlocale() for libtest tests to test the effects of locale-induced
1400 libc changes on libcurl.
1402 - Fixed a couple more locale-dependent toupper conversions, mainly for
1403 clarity. This does fix one problem that causes ;type=i FTP URLs
1404 to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
1405 used (test case 561)
1407 - Added tests 561 and 1091 through 1094 to test various combinations
1408 of ;type= and ;mode= URLs that could potentially fail in the Turkish
1411 Daniel Stenberg (20 Jan 2009)
1412 - Lisa Xu pointed out that the ssh.obj file was missing from the
1413 lib/Makefile.vc6 file (and thus from the vc8 and vc9 ones too).
1415 Version 7.19.3 (19 January 2009)
1417 Daniel Stenberg (16 Jan 2009)
1418 - Andrew de los Reyes fixed curlbuild.h for "generic" gcc builds on PPC, both
1421 Daniel Stenberg (15 Jan 2009)
1422 - Tim Ansell fixed a compiler warning in lib/cookie.c
1424 Daniel Stenberg (14 Jan 2009)
1425 - Grant Erickson fixed timeouts for TFTP such that specifying a
1426 connect-timeout, a max-time or both options work correctly and as expected
1427 by passing the correct boolean value to Curl_timeleft via the
1428 'duringconnect' parameter.
1430 With this small change, curl TFTP now behaves as expected (and likely as
1431 originally-designed):
1433 1) For non-existent or unreachable dotted IP addresses:
1435 a) With no options, follows the default curl 300s timeout...
1436 b) With --connect-timeout only, follows that value...
1437 c) With --max-time only, follows that value...
1438 d) With both --connect-timeout and --max-time, follows the smaller value...
1440 and times out with a "curl: (7) Couldn't connect to server" error.
1442 2) For transfers to/from a valid host:
1444 a) With no options, follows default curl 300s timeout for the
1445 first XRQ/DATA/ACK transaction and the default TFTP 3600s
1446 timeout for the remainder of the transfer...
1448 b) With --connect-time only, follows that value for the
1449 first XRQ/DATA/ACK transaction and the default TFTP 3600s
1450 timeout for the remainder of the transfer...
1452 c) With --max-time only, follows that value for the first
1453 XRQ/DATA/ACK transaction and for the remainder of the
1456 d) With both --connect-timeout and --max-time, follows the former
1457 for the first XRQ/DATA/ACK transaction and the latter for the
1458 remainder of the transfer...
1460 and times out with a "curl: (28) Timeout was reached" error as
1463 Daniel Stenberg (13 Jan 2009)
1464 - Michael Wallner fixed a NULL pointer deref when calling
1465 curl_easy_setup(curl, CURLOPT_COOKIELIST, "SESS") on a CURL handle with no
1468 - Stefan Teleman brought a patch to fix the default curlbuild.h file for the
1471 Daniel Stenberg (12 Jan 2009)
1472 - Based on bug report #2498665 (http://curl.haxx.se/bug/view.cgi?id=2498665)
1473 by Daniel Black, I've now added magic to the configure script that makes it
1474 use pkg-config to detect gnutls details as well if the existing method
1475 (using libgnutls-config) fails. While doing this, I cleaned up and unified
1476 the pkg-config usage when detecting openssl and nss as well.
1478 Daniel Stenberg (11 Jan 2009)
1479 - Karl Moerder brought the patch that creates vc9 Makefiles, and I made
1480 'maketgz' now use the actual makefile targets to do the VC8 and VC9
1483 Daniel Stenberg (10 Jan 2009)
1484 - Emil Romanus fixed:
1486 When using the multi interface over HTTP and the server returns a Location
1487 header, the running easy handle will get stuck in the CURLM_STATE_PERFORM
1488 state, leaving the external event loop stuck waiting for data from the
1489 ingoing socket (when using the curl_multi_socket_action stuff). While this
1490 bug was pretty hard to find, it seems to require only a one-line fix. The
1491 break statement on line 1374 in multi.c caused the function to skip the call
1494 How to reproduce this bug? Well, that's another question. evhiperfifo.c in
1495 the examples directory chokes on this bug only _sometimes_, probably
1496 depending on how fast the URLs are added. One way of testing the bug out is
1497 writing to hiper.fifo from more than one source at the same time.
1499 Daniel Fandrich (7 Jan 2009)
1500 - Unified much of the SessionHandle initialization done in Curl_open() and
1501 curl_easy_reset() by creating Curl_init_userdefined(). This had the side
1502 effect of fixing curl_easy_reset() so it now also resets
1503 CURLOPT_FTP_FILEMETHOD and CURLOPT_SSL_SESSIONID_CACHE
1505 Daniel Stenberg (7 Jan 2009)
1506 - Rob Crittenden did once again provide an NSS update:
1508 I have to jump through a few hoops now with the NSS library initialization
1509 since another part of an application may have already initialized NSS by the
1510 time Curl gets invoked. This patch is more careful to only shutdown the NSS
1511 library if Curl did the initialization.
1513 It also adds in a bit of code to set the default ciphers if the app that
1514 call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
1515 ciphers. One might argue that this lets other application developers get
1516 lazy and/or they aren't using the NSS API correctly, and you'd be right.
1517 But still, this will avoid terribly difficult-to-trace crashes and is

1521 - 'reconf' is removed since we rather have users use 'buildconf'
1523 Daniel Stenberg (31 Dec 2008)
1524 - Bas Mevissen reported http://curl.haxx.se/bug/view.cgi?id=2479030 pointing
1525 out that 'reconf' didn't properly point out the m4 subdirectory when running
1528 Daniel Stenberg (29 Dec 2008)
1529 - Phil Lisiecki filed bug report #2413067
1530 (http://curl.haxx.se/bug/view.cgi?id=2413067) that identified a problem that
1531 would cause libcurl to mark a DNS cache entry "in use" eternally if the
1532 subsequence TCP connect failed. It would thus never get pruned and refreshed
1533 as it should've been.
1535 Phil provided his own patch to this problem that while it seemed to work
1536 wasn't complete and thus I wrote my own fix to the problem.
1538 Daniel Stenberg (28 Dec 2008)
1539 - Peter Korsgaard fixed building libcurl with "configure --with-ssl
1542 - Anthony Bryan fixed more language and spelling flaws in man pages.
1544 Daniel Stenberg (22 Dec 2008)
1545 - Given a recent enough libssh2, libcurl can now seek/resume with SFTP even
1546 on file indexes beyond 2 or 4GB.
1548 - Anthony Bryan provided a set of patches that cleaned up manual language,
1549 corrected spellings and more.
1551 Daniel Stenberg (20 Dec 2008)
1552 - Igor Novoseltsev fixed a bad situation for the multi_socket() API when doing
1553 pipelining, as libcurl could then easily get confused and A) work on the
1554 handle that was not "first in queue" on a pipeline, or even B) tell the app
1555 to REMOVE a socket while it was in use by a second handle in a pipeline. Both
1556 errors caused hanging or stalling applications.
1558 Daniel Stenberg (19 Dec 2008)
1559 - curl_multi_timeout() could return a timeout value of 0 even though nothing
1560 was actually ready to get done, as the internal time resolution is higher
1561 than the returned millisecond timer. Therefore it could cause applications
1562 running on fast processors to do short bursts of busy-loops.
1563 curl_multi_timeout() will now only return 0 if the timeout is actually
1566 - Using the libssh2 0.19 function libssh2_session_block_directions(), libcurl
1567 now has an improved ability to do right when the multi interface (both
1568 "regular" and multi_socket) is used for SCP and SFTP transfers. This should
1569 result in (much) less busy-loop situations and thus less CPU usage with no
1572 Daniel Stenberg (17 Dec 2008)
1573 - SCP and SFTP with the multi interface had the same flaw: the 'DONE'
1574 operation didn't complete properly if the EAGAIN equivalent was returned but
1575 libcurl would simply continue with a half-completed close operation
1576 performed. This ruined persistent connection re-use and cause some
1577 SSH-protocol errors in general. The correction is unfortunately adding a
1578 blocking function - doing it entirely non-blocking should be considered for
1581 Gisle Vanem (16 Dec 2008)
1582 - Added the possibility to use the Watt-32 tcp/ip stack under Windows.
1583 The change simply involved adding a USE_WATT32 section in the
1584 config-win32.h files (under ./lib and ./src). This section disables
1585 the use of any Winsock headers.
1587 Daniel Stenberg (16 Dec 2008)
1588 - libssh2_sftp_last_error() was wrongly used at some places in libcurl which
1589 made libcurl sometimes not properly abort problematic SFTP transfers.
1591 Daniel Stenberg (12 Dec 2008)
1592 - More work with Igor Novoseltsev to first fix the remaining stuff for
1593 removing easy handles from multi handles when the easy handle is/was within
1594 a HTTP pipeline. His bug report #2351653
1595 (http://curl.haxx.se/bug/view.cgi?id=2351653) was also related and was
1596 eventually fixed by a patch by Igor himself.
1598 Yang Tse (12 Dec 2008)
1599 - Patrick Monnerat fixed a build regression, introduced in 7.19.2, affecting
1600 OS/400 compilations with IPv6 enabled.
1602 Daniel Stenberg (12 Dec 2008)
1603 - Mark Karpeles filed bug report #2416182 titled "crash in ConnectionExists
1604 when using duphandle+curl_mutli"
1605 (http://curl.haxx.se/bug/view.cgi?id=2416182) which showed that
1606 curl_easy_duphandle() wrongly also copied the pointer to the connection
1607 cache, which was plain wrong and caused a segfault if the handle would be
1608 used in a different multi handle than the handle it was duplicated from.
1610 Daniel Stenberg (11 Dec 2008)
1611 - Keshav Krity found out that libcurl failed to deal with dotted IPv6
1612 addresses if they were very long (>39 letters) due to a too strict address
1613 validity parser. It now accepts addresses up to 45 bytes long.
1615 Daniel Stenberg (11 Dec 2008)
1616 - Internet Explorer had a broken HTTP digest authentication before v7 and
1617 there are servers "out there" that relies on the client doing this broken
1618 Digest authentication. Apache even comes with an option to work with such
1621 The difference is only for URLs that contain a query-part (a '?'-letter and
1622 text to the right of it).
1624 libcurl now supports this quirk, and you enable it by setting the
1625 CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or
1626 CURLOPT_PROXYAUTH options. They are thus individually controlled to server
1629 (note that there's no way to activate this with the curl tool yet)
1631 Daniel Fandrich (9 Dec 2008)
1632 - Added test cases 1089 and 1090 to test --write-out after a redirect to
1633 test a report that the size didn't work, but these test cases pass.
1635 - Documented CURLOPT_CONNECT_ONLY as being useful only on HTTP URLs.
1637 Daniel Stenberg (9 Dec 2008)
1638 - Ken Hirsch simplified how libcurl does FTPS: now it doesn't assume any
1639 particular state for the control connection like it did before for implicit
1640 FTPS (libcurl assumed such control connections to be encrypted while some
1641 FTPS servers such as FileZilla assumes such connections to be clear
1642 mode). Use the CURLOPT_USE_SSL option to set your desired level.
1644 Daniel Stenberg (8 Dec 2008)
1645 - Fred Machado posted about a weird FTP problem on the curl-users list and when
1646 researching it, it turned out he got a 550 response back from a SIZE command
1647 and then I fell over the text in RFC3659 that says:
1649 The presence of the 550 error response to a SIZE command MUST NOT be taken
1650 by the client as an indication that the file cannot be transferred in the
1651 current MODE and TYPE.
1653 In other words: the change I did on September 30th 2008 and that has been
1654 included in the last two releases were a regression and a bad idea. We MUST
1655 NOT take a 550 response from SIZE as a hint that the file doesn't exist.
1657 - Christian Krause filed bug #2221237
1658 (http://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite
1659 loop during GSS authentication given some specific conditions. With his
1660 patience and great feedback I managed to narrow down the problem and
1661 eventually fix it although I can't test any of this myself!
1663 Daniel Fandrich (3 Dec 2008)
1664 - Fixed the getifaddrs version of Curl_if2ip to work on systems without IPv6
1665 support (e.g. Minix)
1667 Daniel Stenberg (3 Dec 2008)
1668 - Igor Novoseltsev filed bug #2351645
1669 (http://curl.haxx.se/bug/view.cgi?id=2351645) that identified a problem with
1670 the multi interface that occured if you removed an easy handle while in
1671 progress and the handle was used in a HTTP pipeline.
1673 - Pawel Kierski pointed out a mistake in the cookie code that could lead to a
1674 bad fclose() after a fatal error had occured.
1675 (http://curl.haxx.se/bug/view.cgi?id=2382219)
1677 Daniel Fandrich (25 Nov 2008)
1678 - If a HTTP request is Basic and num is already >=1000, the HTTP test
1679 server adds 1 to num to get the data section to return. This allows
1680 testing authentication negotiations using the Basic authentication
1683 - Added tests 1087 and 1088 to test Basic authentication on a redirect
1684 with and without --location-trusted
1686 Daniel Stenberg (24 Nov 2008)
1687 - Based on a patch by Vlad Grachov, libcurl now uses a new libssh2 0.19
1688 function when built to support SCP and SFTP that helps the library to know
1689 in which direction a particular libssh2 operation would return EAGAIN so
1690 that libcurl knows what socket conditions to wait for before trying the
1691 function call again. Previously (and still when using libssh2 0.18 or
1692 earlier), libcurl will busy-loop in this situation when the easy interface
1695 Daniel Fandrich (20 Nov 2008)
1696 - Automatically detect OpenBSD's CA cert bundle.
1698 Daniel Stenberg (19 Nov 2008)
1699 - I removed the default use of "Pragma: no-cache" from libcurl when a proxy is
1700 used. It has been used since forever but it was never a good idea to use
1701 unless explicitly asked for.
1703 - Josef Wolf's extension that allows a $TESTDIR/gdbinit$testnum file that when
1704 you use runtests.pl -g, will be sourced by gdb to allow additional fancy or
1705 whatever you see fit
1707 - Christian Krause reported and fixed a memory leak that would occur with HTTP
1708 GSS/kerberos authentication (http://curl.haxx.se/bug/view.cgi?id=2284386)
1710 - Andreas Wurf and Markus Koetter helped me analyze a problem that Andreas got
1711 when uploading files to a single FTP server using multiple easy handle
1712 handles with the multi interface. Occasionally a handle would stall in
1715 The problem turned out to be a side-effect of the ConnectionExists()
1716 function's eagerness to re-use a handle for HTTP pipelining so it would
1717 select it even if already being in use, due to an inadequate check for its
1718 chances of being used for pipelnining.
1720 Daniel Fandrich (17 Nov 2008)
1721 - Added more compiler warning options for gcc 4.3
1723 Yang Tse (17 Nov 2008)
1724 - Fix a remaining problem in the inet_pton() runtime configure check. And
1725 fix internal Curl_inet_pton() failures to reject certain malformed literals.
1727 - Make configure script check if ioctl with the SIOCGIFADDR command can be
1728 used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate.
1730 Daniel Stenberg (16 Nov 2008)
1731 - Christian Krause fixed a build failure when building with gss support
1732 enabled and FTP disabled.
1734 - Added check for NULL returns from strdup() in src/main.c and lib/formdata.c
1735 - reported by Jim Meyering also prevent buffer overflow on MSDOS when you do
1736 for example -O on a url with a file name part longer than PATH_MAX letters
1738 - lib/nss.c fixes based on the report by Jim Meyering: I went over and added
1739 checks for return codes for all calls to malloc and strdup that were
1740 missing. I also changed a few malloc(13) to use arrays on the stack and a
1741 few malloc(PATH_MAX) to instead use aprintf() to lower memory use.
1743 - I fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is
1746 Daniel Fandrich (14 Nov 2008)
1747 - Added .xml as one of the few common file extensions known by the multipart
1750 - Added some #ifdefs around header files and change the EAGAIN test to
1751 fix compilation on Cell (reported by Jeff Curley).
1753 Yang Tse (14 Nov 2008)
1754 - Fixed several configure script issues affecting checks for inet_ntoa_r(),
1755 inet_ntop(), inet_pton(), getifaddrs(), fcntl() and getaddrinfo().
1757 Yang Tse (13 Nov 2008)
1758 - Refactored configure script detection of functions used to set sockets into
1759 non-blocking mode, and decouple function detection from function capability.
