                                  Changelog

Daniel Stenberg (27 Mar 2008)
- As found out and reported by Dan Petitt, libcurl didn't show progress/call
  the progress callback for the first (potentially huge) piece of body data
  sent together with the POST request headers in the initial send().

Daniel Stenberg (25 Mar 2008)
- Made setting the CURLOPT_SSL_CTX_FUNCTION option return a failure in case
  libcurl wasn't built to use OpenSSL as that is a prerequisite for this
  option to function!

Daniel Stenberg (22 Mar 2008)
- Fixed the problem with doing a zero byte SCP transfer, verified with test
  case 617 (which was added by Daniel Fandrich 5 Mar 2008).

Daniel Fandrich (20 Mar 2008)
- Fixed a problem where curl-config --protocols could erroneously show LDAPS
  support when curl didn't even have regular LDAP support.  It looks like
  this could happen when the --enable-ldaps configure switch is given but
  configure couldn't find the LDAP headers or libraries.

Michal Marek (20 Mar 2008)
- Added --with-ca-path=DIRECTORY configure option to use an openSSL CApath by
  default instead of a ca bundle. The configure script will also look for a
  ca path if no ca bundle is found and no option given.

- Fixed detection of previously installed curl-ca-bundle.crt

Daniel Fandrich (18 Mar 2008)
- Added test 626 to reproduce an infinite loop when given an invalid
  SFTP quote command reported by Vincent Le Normand, and fixed it.

Michal Marek (18 Mar 2008)
- Added curl_easy_getinfo typechecker.

- Added macros for curl_share_setopt and curl_multi_setopt to check at least
  the correct number of arguments.

Daniel Fandrich (13 Mar 2008)
- Added tests 622-625 to test SFTP/SCP uploads. Test 625 was an attempt to
  reproduce the --ftp-create-dirs problem reported by Brian Ulm, but that
  seems to need a call curl_easy_reset() which this test case doesn't do.

Daniel Stenberg (13 Mar 2008)
- Brian Ulm figured out that if you did an SFTP upload with
  CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
  handle and uploaded another file to another directory that needed to be
  created, the second upload would fail. Another case of a state variable that
  wasn't properly reset between requests.

- I rewrote the 100-continue code to use a single state variable instead of
  the previous two ones. I think it made the logic somewhat clearer.

Daniel Stenberg (11 Mar 2008)
- Dmitry Popov filed bug report #1911069
  (http://curl.haxx.se/bug/view.cgi?id=1911069) that identified a race
  condition in the name resolver code when the DNS cache is shared between
  multiple easy handles, each running in simultaneous threads that could cause
  crashes.

- Added a macro for curl_easy_setopt() that accepts three arguments and simply
  does nothing with them, just to make sure libcurl users always use three
  arguments to this function. Due to its use of ... for the third argument, it
  is otherwise hard to detect abuse.

Michal Marek (11 Mar 2008)
- Added a type checking macro for curl_easy_setopt(), needs gcc-4.3 and only
  works in C mode atm (http://curl.haxx.se/mail/lib-2008-02/0267.html ,
  http://curl.haxx.se/mail/lib-2008-02/0292.html )

Daniel Fandrich (10 Mar 2008)
- Added tests 618-621 to test SFTP/SCP transfers of more than one file
  (test 620 tests the just-fixed problem reported by Brian Ulm).

Daniel Stenberg (9 Mar 2008)
- Brian Ulm reported a crash when doing a second SFTP transfer on a re-used
  easy handle if curl_easy_reset() was used between them. I fixed it and Brian
  verified that it cured his problem.

- Brian Ulm reported that if you first tried to download a non-existing SFTP
  file and then fetched an existing one and re-used the handle, libcurl would
  still report the second one as non-existing as well! I fixed it and Brian
  verified that it cured his problem.

Michal Marek (6 Mar 2008)
- Fix the gssapi configure check to detect newer MIT Kerberos (patch by
  Michael Calmer)

Yang Tse (6 Mar 2008)
- Fix regression on Curl_socket_ready() and Curl_poll() so that these will
  again fail on select/poll errors different than EINTR.

Daniel Fandrich (5 Mar 2008)
- Fixed the test harness so it will write out zero-length data files.

- Added tests 616 and 617 to see how SFTP and SCP cope with zero-length
  files, as questioned by Mike Protts. SFTP does for me but SCP doesn't
  so test 617 is disabled for now.

Daniel S (4 Mar 2008)
- Mike Protts brought a patch that makes resumed transfers work with SFTP.

Daniel S (1 Mar 2008)
- Anatoli Tubman found and fixed a crash with Negotiate authentication used on
  a re-used connection where both requests used Negotiate.

Guenter Knauf (26 Feb 2008)
- Kaspar Brand provided a patch to support server name indication (RFC 4366).

Daniel S (25 Feb 2008)
- Kaspar Brand made GnuTLS-built libcurl properly acknowledge the option that
  forces it to prefer SSLv3.

Daniel S (23 Feb 2008)
- Sam Listopad provided a patch in feature-request #1900014
  http://curl.haxx.se/bug/feature.cgi?id=1900014 that makes libcurl (built to
  use OpenSSL) support a full chain of certificates in a given PKCS12
  certificate.

Daniel S (22 Feb 2008)
- Georg Lippitsch made the src/Makefile.vc6 makefile use the same memory model
  options as the lib/Makefile.vc6 already did.

Daniel S (21 Feb 2008)
- Zmey Petroff found a crash when libcurl accessed a NULL pointer, which
  happened if you set the connection cache size to 1 and for example failed to
  login to an FTP site. Bug report #1896698
  (http://curl.haxx.se/bug/view.cgi?id=1896698)

Daniel S (20 Feb 2008)
- Fixed test case 405 to not fail when libcurl is built with GnuTLS

- Based on initial work done by Gautam Kachroo to address a bug, we now keep
  better control at the exact state of the connection's SSL status so that we
  know exactly when it has completed the SSL negotiation or not so that there
  won't be accidental re-uses of connections that are wrongly believed to be
  in SSL-completed-negotiate state.

- We no longer support setting the CURLOPT_URL option from inside a callback
  such as the CURLOPT_SSL_CTX_FUNCTION one treat that as if it was a Location:
  following. The patch that introduced this feature was done for 7.11.0, but
  this code and functionality has been broken since about 7.15.4 (March 2006)
  with the introduction of non-blocking OpenSSL "connects".

  It was a hack to begin with and since it doesn't work and hasn't worked
  correctly for a long time and nobody has even noticed, I consider it a very
  suitable subject for plain removal. And so it was done.

Guenter Knauf (19 Feb 2008)
- We do no longer support SSLv2 by default since it has known flaws.
  Kaspar Brand provided a patch for all supported SSL toolkits.
 
Daniel Fandrich (19 Feb 2008)
- Added test309 to test HTTP redirect to HTTPS URL

Daniel S (18 Feb 2008)
- We're no longer providing a very old ca-bundle in the curl tarball. You can
  get a fresh one downloaded and created with 'make ca-bundle' or you can get
  one from here => http://curl.haxx.se/docs/caextract.html if you want a fresh
  new one extracted from Mozilla's recent list of ca certs.

  The configure option --with-ca-bundle now lets you specify what file to use
  as default ca bundle for your build. If not specified, the configure script
  will check a few known standard places for a global ca cert to use.

Daniel S (17 Feb 2008)
- Jerome Muffat-Meridol helped me fix Curl_done() to close the current
  connection by force when it was called before the entire request is
  completed, simply because we can't know if the connection really can be
  re-used safely at that point.

- Based on the same debugging logic, I've also made Curl_http_done() not
  return CURLE_GOT_NOTHING if called "prematurely". This should have no real
  effect to anything but the code makes more sense like this.
  
Daniel S (15 Feb 2008)
- Made the gnutls code path not even try to get the server cert if no peer
  verification is requested. Previously it would even return failure if gnutls
  failed to get the server cert even though no verification was asked for.
  Public server showing the problem: https://www.net222.caisse-epargne.fr

- Fix my Curl_timeleft() leftover mistake in the gnutls code

- Pooyan McSporran found and fixed a flaw where you first would do a normal
  http request and then you'd reuse the handle and replace the Accept: header,
  as then libcurl would send two Accept: headers!

Daniel S (11 Feb 2008)
- Yang Tse pointed out a few remaining quirks from my timeout refactoring from
  Feb 7 that didn't abort properly on timeouts. These are actually old
  problems but now they should be fixed.

Yang Tse (10 Feb 2008)
