                                  Changelog

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Daniel Stenberg (17 Dec 2009)
- David Byron fixed Curl_ossl_cleanup to actually call ENGINE_cleanup when
  available.
  
- Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I
  was a bit too quick and broke test case 1101 with that change. The order of
  some of the setups is sensitive. I now changed it slightly again to make
  sure we do them in this order:

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

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

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

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

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

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

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

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

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

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

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

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

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

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