                                  Changelog

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 2007)
- 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 2007)
- 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)
- Bug report #1888932 (http://curl.haxx.se/bug/view.cgi?id=1888932) points out
  and provides test program that demonstrates that libcurl might not set error
  description message for error CURLE_COULDNT_RESOLVE_HOST for Windows threaded
  name resolver builds. Fixed now.

Daniel Fandrich (8 Feb 2007)
- Added key words to all SSL-using tests so they can be skipped if necessary.
  Removed a few unnecessary requires SSL statements.

Daniel S (8 Feb 2008)
- Mike Hommey filed and fixed bug report #1889856
  (http://curl.haxx.se/bug/view.cgi?id=1889856): When using the gnutls ssl
  layer, cleaning-up and reinitializing curl ends up with https requests
  failing with "ASN1 parser: Element was not found" errors. Obviously a
  regression added in 7.16.3.

Yang Tse (8 Feb 2008)
- Improved test harness SCP/SFTP start up server verification, doing a real
  connection to the sftp server, authenticating and running a simple sftp
  pwd command using the test harness generated configuration and key files.

Daniel S (8 Feb 2008)
- Günter Knauf added lib/mk-ca-bundle.pl which gets the Firefox ca bundle and
  creates a suitable ca-bundle.crt file in PEM format for use with curl. The
  recommended way to run it is to use 'make ca-bundle' in the build tree root.

Daniel Fandrich (7 Feb 2007)
- Added tests 1022 and 1023 to validate output of curl-config --version and
  --vernum

Daniel S (7 Feb 2008)
- Refactored a lot of timeout code into a few functions in an attempt to make
  them all use the same (hopefully correct) logic to make it less error-prone
  and easier to introduce library-wide where it should be used.

Yang Tse (6 Feb 2008)
- Fix an issue in strdup replacement function when dealing with absolutely
  huge strings. Only systems without a standard strdup would be affected.

Daniel S (3 Feb 2008)
- Dmitry Kurochkin cleaned up the pipelining code and removed the need for and
  use of the "is_in_pipeline" struct field.

- I wrote up and added the threaded-ssl.c example source code that shows how
  to do multi-threaded downloads of HTTPS files with a libcurl that is built
  with OpenSSL. It uses pthreads for the threading.

Daniel S (31 Jan 2008)
- Niklas Angebrand made the cookie support in libcurl properly deal with the
  "HttpOnly" feature introduced by Microsoft and apparently also supported by
  Firefox: http://msdn2.microsoft.com/en-us/library/ms533046.aspx . HttpOnly
  is now supported when received from servers in HTTP headers, when written to
  cookie jars and when read from existing cookie jars.

  I modified test case 31 and 46 to also do some basic HttpOnly testing.

- Dmitry Kurochkin moved several struct fields from the connectdata struct to
  the SingleRequest one to make pipelining better. It is a bit tricky to keep
  them in the right place, to keep things related to the actual request or to
  the actual connection in the right place.

Daniel S (29 Jan 2008)
- Dmitry Kurochkin fixed Curl_done() for pipelining, as it could previously
  crash!

- Michal Marek fixed minor mistake in test case 553 that prevented it from
  working on other IP-addresses or port numbers.

Version 7.18.0 (28 January 2008)

Daniel S (27 Jan 2008)
- Dmitry Kurochkin: In "real world" testing I found more bugs in
  pipelining. Broken connection is not restored and we get into infinite
  loop. It happens because of wrong is_in_pipeline values.

Daniel S (26 Jan 2008)
- Kevin Reed filed bug report #1879375
  (http://curl.haxx.se/bug/view.cgi?id=1879375) which describes how libcurl
  got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
  proxy authentication and the proxy replies with an auth (like NTLM) and then
  closes the connection after that initial informational response.

  libcurl would not properly re-initialize the connection to the proxy and
  continue the auth negotiation like supposed. It does now however, as it will
  now detect if one or more authentication methods were available and asked
  for, and will thus retry the connection and continue from there.

- I made the progress callback get called properly during proxy CONNECT.

Daniel S (23 Jan 2008)
- Igor Franchuk pointed out that CURLOPT_COOKIELIST set to "ALL" leaked
  memory, and so did "SESS". Fixed now.

Yang Tse (22 Jan 2008)
- Check poll.h at configuration time, and use it when sys/poll.h unavailable

Daniel S (22 Jan 2008)
- Dmitry Kurochkin removed the cancelled state for pipelining, as we agreed
  that it is bad anyway. Starting now, removing a handle that is in used in a
  pipeline will break the pipeline - it'll be set back up again but still...

Yang Tse (21 Jan 2008)
- Disable ldap support for cygwin builds, since it breaks whole build process.
  Fixing it will affect other platforms, so it is postponed for another release.

Daniel S (18 Jan 2008)
- Lau Hang Kin found and fixed a problem with the multi interface when doing
  CONNECT over a proxy. curl_multi_fdset() didn't report back the socket
  properly during that state, due to a missing case in the switch in the
  multi_getsock() function.
