                                  Changelog

Daniel Fandrich (4 Feb 2009)
- Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS
  (respectively) when --with-ssl=/usr is used (patch based on FreeBSD).

- Added an explicit buffer limit check in msdosify() (patch based on FreeBSD).
  This couldn't ever overflow in curl, but might if the code were used
  elsewhere or under different conditions.

Daniel Stenberg (3 Feb 2009)
- Hidemoto Nakada provided a small fix that makes it possible to get the
  CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with
  CURLOPT_NOBODY set true.

Daniel Stenberg (2 Feb 2009)
- Patrick Scott found a rather large memory leak when using the multi
  interface and setting CURLMOPT_MAXCONNECTS to something less than the number
  of handles you add to the multi handle. All the connections that didn't fit
  in the cache would not be properly disconnected nor freed!

- Craig A West brought us: libcurl now defaults to do CONNECT with HTTP
  version 1.1 instead of 1.0 like before. This change also introduces the new
  proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
  switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
  option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.

  I updated all test cases cases that use CONNECT and I tried to do some using
  --proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.

Daniel Stenberg (31 Jan 2009)
- When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
  enabled, we can now take advantage of its brand new AF_UNSPEC support in
  ares_gethostbyname(). This makes test case 241 finally run fine for me with
  this setup since it now parses the "::1 ip6-localhost" line fine in my
  /etc/hosts file!

Daniel Stenberg (30 Jan 2009)
- Scott Cantor filed bug report #2550061
  (http://curl.haxx.se/bug/view.cgi?id=2550061) mentioning that I failed to
  properly make sure that the VC9 makefiles got included in the latest
  release. I've now fixed the release script and verified it so next release
  will hopefully include them properly!

Daniel Fandrich (30 Jan 2009)
- Fixed --disable-proxy for FTP and SOCKS. Thanks to Daniel Egger for
  reporting.

Yang Tse (29 Jan 2009)
- Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
  Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
  named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
  Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
  SSPI library using it now in the same way as it was done in http_ntlm.c.

Daniel Stenberg (28 Jan 2009)
- Markus Moeller introduced two new options to libcurl:
  CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl
  to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
  options called --socks5-gssapi-service and --socks5-gssapi-nec to enable
  these.

Daniel Stenberg (26 Jan 2009)
- Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app
  to set desired block size to use for TFTP transfers instead of the default
  512 bytes.

- The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
  disable "rfc4507bis session ticket support".  rfc4507bis was later turned
  into the proper RFC5077 it seems: http://tools.ietf.org/html/rfc5077

  The enabled extension concerns the session management. I wonder how often
  libcurl stops a connection and then resumes a TLS session. also, sending the
  session data is some overhead. .I suggest that you just use your proposed
  patch (which explicitly disables TICKET).

  If someone writes an application with libcurl and openssl who wants to
  enable the feature, one can do this in the SSL callback.

  Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
  on the proper action.

- Alexey Borzov filed bug report #2535504
  (http://curl.haxx.se/bug/view.cgi?id=2535504) pointing out that realms with
  quoted quotation marks in HTTP Digest headers didn't work. I've now added 
  test case 1095 that verifies my fix.

- Craig A West brought CURLOPT_NOPROXY and the corresponding --noproxy option.
  They basically offer the same thing the NO_PROXY environment variable only
  offered previously: list a set of host names that shall not use the proxy
  even if one is specified.

Daniel Fandrich (20 Jan 2009)
- Call setlocale() for libtest tests to test the effects of locale-induced
  libc changes on libcurl.

- Fixed a couple more locale-dependent toupper conversions, mainly for
  clarity.  This does fix one problem that causes ;type=i FTP URLs
  to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
  used (test case 561)

- Added tests 561 and 1091 through 1094 to test various combinations
  of ;type= and ;mode= URLs that could potentially fail in the Turkish
  locale.

Daniel Stenberg (20 Jan 2009)
- Lisa Xu pointed out that the ssh.obj file was missing from the
  lib/Makefile.vc6 file (and thus from the vc8 and vc9 ones too).

Version 7.19.3 (19 January 2009)

Daniel Stenberg (16 Jan 2009)
- Andrew de los Reyes fixed curlbuild.h for "generic" gcc builds on PPC, both
  32 bit and 64 bit.

Daniel Stenberg (15 Jan 2009)
- Tim Ansell fixed a compiler warning in lib/cookie.c

Daniel Stenberg (14 Jan 2009)
- Grant Erickson fixed timeouts for TFTP such that specifying a
  connect-timeout, a max-time or both options work correctly and as expected
  by passing the correct boolean value to Curl_timeleft via the
  'duringconnect' parameter.

  With this small change, curl TFTP now behaves as expected (and likely as
  originally-designed):

  1) For non-existent or unreachable dotted IP addresses:

   a) With no options, follows the default curl 300s timeout...
   b) With --connect-timeout only, follows that value...
   c) With --max-time only, follows that value...
   d) With both --connect-timeout and --max-time, follows the smaller value...

   and times out with a "curl: (7) Couldn't connect to server" error.

  2) For transfers to/from a valid host:

   a) With no options, follows default curl 300s timeout for the
      first XRQ/DATA/ACK transaction and the default TFTP 3600s
      timeout for the remainder of the transfer...

   b) With --connect-time only, follows that value for the
      first XRQ/DATA/ACK transaction and the default TFTP 3600s
      timeout for the remainder of the transfer...

   c) With --max-time only, follows that value for the first
      XRQ/DATA/ACK transaction and for the remainder of the
      transfer...

   d) With both --connect-timeout and --max-time, follows the former
      for the first XRQ/DATA/ACK transaction and the latter for the
      remainder of the transfer...

   and times out with a "curl: (28) Timeout was reached" error as
   appropriate.

Daniel Stenberg (13 Jan 2009)
- Michael Wallner fixed a NULL pointer deref when calling
  curl_easy_setup(curl, CURLOPT_COOKIELIST, "SESS") on a CURL handle with no
  cookies data.

- Stefan Teleman brought a patch to fix the default curlbuild.h file for the
  SunPro compilers.

Daniel Stenberg (12 Jan 2009)
- Based on bug report #2498665 (http://curl.haxx.se/bug/view.cgi?id=2498665)
  by Daniel Black, I've now added magic to the configure script that makes it
  use pkg-config to detect gnutls details as well if the existing method
  (using libgnutls-config) fails. While doing this, I cleaned up and unified
  the pkg-config usage when detecting openssl and nss as well.

Daniel Stenberg (11 Jan 2009)
- Karl Moerder brought the patch that creates vc9 Makefiles, and I made
  'maketgz' now use the actual makefile targets to do the VC8 and VC9
  makefiles.

Daniel Stenberg (10 Jan 2009)
- Emil Romanus fixed:

  When using the multi interface over HTTP and the server returns a Location
  header, the running easy handle will get stuck in the CURLM_STATE_PERFORM
  state, leaving the external event loop stuck waiting for data from the
  ingoing socket (when using the curl_multi_socket_action stuff). While this
  bug was pretty hard to find, it seems to require only a one-line fix. The
  break statement on line 1374 in multi.c caused the function to skip the call
  to multistate().

  How to reproduce this bug? Well, that's another question.  evhiperfifo.c in
  the examples directory chokes on this bug only _sometimes_, probably
  depending on how fast the URLs are added. One way of testing the bug out is
  writing to hiper.fifo from more than one source at the same time.

Daniel Fandrich (7 Jan 2009)
- Unified much of the SessionHandle initialization done in Curl_open() and
  curl_easy_reset() by creating Curl_init_userdefined(). This had the side
  effect of fixing curl_easy_reset() so it now also resets
  CURLOPT_FTP_FILEMETHOD and CURLOPT_SSL_SESSIONID_CACHE

Daniel Stenberg (7 Jan 2009)
- Rob Crittenden did once again provide an NSS update:

  I have to jump through a few hoops now with the NSS library initialization
  since another part of an application may have already initialized NSS by the
  time Curl gets invoked. This patch is more careful to only shutdown the NSS
  library if Curl did the initialization.

  It also adds in a bit of code to set the default ciphers if the app that
  call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
  ciphers. One might argue that this lets other application developers get
  lazy and/or they aren't using the NSS API correctly, and you'd be right.
  But still, this will avoid terribly difficult-to-trace crashes and is
  generally helpful.

Daniel Stenberg (1 Jan 2009)
- 'reconf' is removed since we rather have users use 'buildconf'

Daniel Stenberg (31 Dec 2008)
- Bas Mevissen reported http://curl.haxx.se/bug/view.cgi?id=2479030 pointing
  out that 'reconf' didn't properly point out the m4 subdirectory when running
  aclocal.

Daniel Stenberg (29 Dec 2008)
 - Phil Lisiecki filed bug report #2413067
  (http://curl.haxx.se/bug/view.cgi?id=2413067) that identified a problem that
  would cause libcurl to mark a DNS cache entry "in use" eternally if the
  subsequence TCP connect failed. It would thus never get pruned and refreshed
  as it should've been.

  Phil provided his own patch to this problem that while it seemed to work
  wasn't complete and thus I wrote my own fix to the problem.

Daniel Stenberg (28 Dec 2008)
- Peter Korsgaard fixed building libcurl with "configure --with-ssl
  --disable-verbose".
  
- Anthony Bryan fixed more language and spelling flaws in man pages.

Daniel Stenberg (22 Dec 2008)
- Given a recent enough libssh2, libcurl can now seek/resume with SFTP even
  on file indexes beyond 2 or 4GB.

- Anthony Bryan provided a set of patches that cleaned up manual language,
  corrected spellings and more.

Daniel Stenberg (20 Dec 2008)
- Igor Novoseltsev fixed a bad situation for the multi_socket() API when doing
  pipelining, as libcurl could then easily get confused and A) work on the
  handle that was not "first in queue" on a pipeline, or even B) tell the app
  to REMOVE a socket while it was in use by a second handle in a pipeline. Both
  errors caused hanging or stalling applications.

Daniel Stenberg (19 Dec 2008)
- curl_multi_timeout() could return a timeout value of 0 even though nothing
  was actually ready to get done, as the internal time resolution is higher
  than the returned millisecond timer. Therefore it could cause applications
  running on fast processors to do short bursts of busy-loops.
  curl_multi_timeout() will now only return 0 if the timeout is actually
  alreay triggered.

- Using the libssh2 0.19 function libssh2_session_block_directions(), libcurl
  now has an improved ability to do right when the multi interface (both
  "regular" and multi_socket) is used for SCP and SFTP transfers. This should
  result in (much) less busy-loop situations and thus less CPU usage with no
  speed loss.

Daniel Stenberg (17 Dec 2008)
- SCP and SFTP with the multi interface had the same flaw: the 'DONE'
  operation didn't complete properly if the EAGAIN equivalent was returned but
  libcurl would simply continue with a half-completed close operation
  performed. This ruined persistent connection re-use and cause some
  SSH-protocol errors in general. The correction is unfortunately adding a
  blocking function - doing it entirely non-blocking should be considered for
  a better fix.

Gisle Vanem (16 Dec 2008)
- Added the possibility to use the Watt-32 tcp/ip stack under Windows.
  The change simply involved adding a USE_WATT32 section in the
  config-win32.h files (under ./lib and ./src). This section disables
  the use of any Winsock headers.

Daniel Stenberg (16 Dec 2008)
- libssh2_sftp_last_error() was wrongly used at some places in libcurl which
  made libcurl sometimes not properly abort problematic SFTP transfers.

Daniel Stenberg (12 Dec 2008)
- More work with Igor Novoseltsev to first fix the remaining stuff for
  removing easy handles from multi handles when the easy handle is/was within
  a HTTP pipeline. His bug report #2351653
  (http://curl.haxx.se/bug/view.cgi?id=2351653) was also related and was
  eventually fixed by a patch by Igor himself.

Yang Tse (12 Dec 2008)
- Patrick Monnerat fixed a build regression, introduced in 7.19.2, affecting
  OS/400 compilations with IPv6 enabled.

Daniel Stenberg (12 Dec 2008)
- Mark Karpeles filed bug report #2416182 titled "crash in ConnectionExists
  when using duphandle+curl_mutli"
  (http://curl.haxx.se/bug/view.cgi?id=2416182) which showed that
  curl_easy_duphandle() wrongly also copied the pointer to the connection
  cache, which was plain wrong and caused a segfault if the handle would be
  used in a different multi handle than the handle it was duplicated from.

Daniel Stenberg (11 Dec 2008)
- Keshav Krity found out that libcurl failed to deal with dotted IPv6
  addresses if they were very long (>39 letters) due to a too strict address
  validity parser. It now accepts addresses up to 45 bytes long.

Daniel Stenberg (11 Dec 2008)
- Internet Explorer had a broken HTTP digest authentication before v7 and
  there are servers "out there" that relies on the client doing this broken
  Digest authentication. Apache even comes with an option to work with such
  broken clients.

  The difference is only for URLs that contain a query-part (a '?'-letter and
  text to the right of it).

  libcurl now supports this quirk, and you enable it by setting the
  CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or
  CURLOPT_PROXYAUTH options. They are thus individually controlled to server
  and proxy.

  (note that there's no way to activate this with the curl tool yet)

Daniel Fandrich (9 Dec 2008)
- Added test cases 1089 and 1090 to test --write-out after a redirect to
  test a report that the size didn't work, but these test cases pass.

- Documented CURLOPT_CONNECT_ONLY as being useful only on HTTP URLs.

Daniel Stenberg (9 Dec 2008)
- Ken Hirsch simplified how libcurl does FTPS: now it doesn't assume any
  particular state for the control connection like it did before for implicit
  FTPS (libcurl assumed such control connections to be encrypted while some
  FTPS servers such as FileZilla assumes such connections to be clear
  mode). Use the CURLOPT_USE_SSL option to set your desired level.

Daniel Stenberg (8 Dec 2008)
- Fred Machado posted about a weird FTP problem on the curl-users list and when
  researching it, it turned out he got a 550 response back from a SIZE command
  and then I fell over the text in RFC3659 that says:

   The presence of the 550 error response to a SIZE command MUST NOT be taken
   by the client as an indication that the file cannot be transferred in the
   current MODE and TYPE.

  In other words: the change I did on September 30th 2008 and that has been
  included in the last two releases were a regression and a bad idea. We MUST
  NOT take a 550 response from SIZE as a hint that the file doesn't exist.

- Christian Krause filed bug #2221237
  (http://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite
  loop during GSS authentication given some specific conditions. With his
  patience and great feedback I managed to narrow down the problem and
  eventually fix it although I can't test any of this myself!

Daniel Fandrich (3 Dec 2008)
- Fixed the getifaddrs version of Curl_if2ip to work on systems without IPv6
  support (e.g. Minix)

Daniel Stenberg (3 Dec 2008)
- Igor Novoseltsev filed bug #2351645
  (http://curl.haxx.se/bug/view.cgi?id=2351645) that identified a problem with
  the multi interface that occured if you removed an easy handle while in
  progress and the handle was used in a HTTP pipeline.

- Pawel Kierski pointed out a mistake in the cookie code that could lead to a
  bad fclose() after a fatal error had occured.
  (http://curl.haxx.se/bug/view.cgi?id=2382219)

Daniel Fandrich (25 Nov 2008)
- If a HTTP request is Basic and num is already >=1000, the HTTP test
  server adds 1 to num to get the data section to return. This allows
  testing authentication negotiations using the Basic authentication
  method.

- Added tests 1087 and 1088 to test Basic authentication on a redirect
  with and without --location-trusted

Daniel Stenberg (24 Nov 2008)
- Based on a patch by Vlad Grachov, libcurl now uses a new libssh2 0.19
  function when built to support SCP and SFTP that helps the library to know
  in which direction a particular libssh2 operation would return EAGAIN so
  that libcurl knows what socket conditions to wait for before trying the
  function call again. Previously (and still when using libssh2 0.18 or
  earlier), libcurl will busy-loop in this situation when the easy interface
  is used!

Daniel Fandrich (20 Nov 2008)
- Automatically detect OpenBSD's CA cert bundle.

Daniel Stenberg (19 Nov 2008)
- I removed the default use of "Pragma: no-cache" from libcurl when a proxy is
  used. It has been used since forever but it was never a good idea to use
  unless explicitly asked for.

- Josef Wolf's extension that allows a $TESTDIR/gdbinit$testnum file that when
  you use runtests.pl -g, will be sourced by gdb to allow additional fancy or
  whatever you see fit

- Christian Krause reported and fixed a memory leak that would occur with HTTP
  GSS/kerberos authentication (http://curl.haxx.se/bug/view.cgi?id=2284386)

- Andreas Wurf and Markus Koetter helped me analyze a problem that Andreas got
  when uploading files to a single FTP server using multiple easy handle
  handles with the multi interface. Occasionally a handle would stall in
  mysterious ways.

  The problem turned out to be a side-effect of the ConnectionExists()
  function's eagerness to re-use a handle for HTTP pipelining so it would
  select it even if already being in use, due to an inadequate check for its
  chances of being used for pipelnining.

Daniel Fandrich (17 Nov 2008)
- Added more compiler warning options for gcc 4.3

Yang Tse (17 Nov 2008)
- Fix a remaining problem in the inet_pton() runtime configure check. And
  fix internal Curl_inet_pton() failures to reject certain malformed literals.

- Make configure script check if ioctl with the SIOCGIFADDR command can be
  used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate.

Daniel Stenberg (16 Nov 2008)
- Christian Krause fixed a build failure when building with gss support
  enabled and FTP disabled.

- Added check for NULL returns from strdup() in src/main.c and lib/formdata.c
  - reported by Jim Meyering also prevent buffer overflow on MSDOS when you do
  for example -O on a url with a file name part longer than PATH_MAX letters

- lib/nss.c fixes based on the report by Jim Meyering: I went over and added
  checks for return codes for all calls to malloc and strdup that were
  missing. I also changed a few malloc(13) to use arrays on the stack and a
  few malloc(PATH_MAX) to instead use aprintf() to lower memory use.

- I fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is
  in use.

Daniel Fandrich (14 Nov 2008)
- Added .xml as one of the few common file extensions known by the multipart
  form generator.

- Added some #ifdefs around header files and change the EAGAIN test to
  fix compilation on Cell (reported by Jeff Curley).

Yang Tse (14 Nov 2008)
- Fixed several configure script issues affecting checks for inet_ntoa_r(),
  inet_ntop(), inet_pton(), getifaddrs(), fcntl() and getaddrinfo().

Yang Tse (13 Nov 2008)
- Refactored configure script detection of functions used to set sockets into
  non-blocking mode, and decouple function detection from function capability.

Version 7.19.2 (13 November 2008)

Michal Marek (13 Nov 2008)
- Fixed a potential data loss in Curl_client_write() when the transfer is
  paused.

Daniel Stenberg (11 Nov 2008)
- Rainer Canavan filed bug #2255627
  (http://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a
  program using libcurl's multi interface to download a HTTPS page with a
  libcurl built powered by OpenSSL, would easily get silly and instead hand
  over SSL details as data instead of the actual HTTP headers and body. This
  happened because libcurl would consider the connection handshake done too
  early. This problem was introduced at September 22nd 2008 with my fix of the
  bug #2107377

  The correct fix is now instead done within the GnuTLS-handling code, as both
  the OpenSSL and the NSS code already deal with this situation in similar
  fashion. I added test case 560 in an attempt to verify this fix, but
  unfortunately it didn't trigger it even before this fix!

Yang Tse (11 Nov 2008)
- Related with bug #2230535 (http://curl.haxx.se/bug/view.cgi?id=2230535)
  Daniel Fandrich noticed that curl_addrinfo was also missing in the build
  process of other four non-configure platforms. Added now.

Daniel Fandrich (7 Nov 2008)
- The getifaddrs() version of Curl_if2ip() crashed when used on a Linux
  system with a TEQL load-balancing device configured, which doesn't
  have an address.  Thanks to Adam Sampson for spotting this (bug #2234923).

Yang Tse (6 Nov 2008)
- Merged existing IPv4 and IPv6 Curl_ip2addr functions into a single one
  which now also takes a protocol address family argument.

- Bug #2230535 (http://curl.haxx.se/bug/view.cgi?id=2230535) pointed out a
  problem with MSVC 6 makefile that caused a build failure. It was noted that
  the curl_addrinfo.obj reference was missing. I took the opportunity to sort
  the list in which this was missing. Issue submitted by John Wilkinson.

Version 7.19.1 (5 November 2008)

Daniel Stenberg (4 Nov 2008)
- CURLINFO_FILETIME now works for file:// transfers as well

Daniel Stenberg (3 Nov 2008)
- Bug #2218480 (http://curl.haxx.se/bug/view.cgi?id=2218480) pointed out a
  problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
  pointer read. I also took the opportunity to clean up this logic (storing of
  the connection's IP address) somewhat as we had it stored in two different
  places and ways previously and they are now unified.

Yang Tse (3 Nov 2008)
- Fix undersized IPv6 address internal buffer. IPv6 address strings longer
  than 35 characters would be truncated.

Daniel Stenberg (2 Nov 2008)
- Daniel Johnson reported and fixed:

  When c-ares isn't enabled, libcurl by default calls getaddrinfo with family
  set to PF_UNSPEC which causes getaddrinfo to return all available addresses,
  both IPv4 and IPv6. Libcurl then tries each one until it can connect. If the
  net connection doesn't support IPv6, libcurl can still fall back to IPv4.

  However, since c-ares doesn't support PF_UNSPEC, when it's used it defaults
  to using family=PF_INET6 and therefore only returns IPv6 addresses when AAAA
  records are available, even if IPv4 addresses are also available. The effect
  is that since my ISP doesn't do IPv6, libcurl can't connect at all to a site
  that has AAAA records. It will work if I explicitly use CURL_IPRESOLVE_V4 or
  --ipv4 with the curl tool. I discovered this when curl would fail to connect
  to seemingly random sites. It turns out they weren't random, they were sites
  with AAAA records.

  So now libcurl defaults to PF_INET... until c-ares has been tought to offer
  both.

Yang Tse (31 Oct 2008)
- Tests 558 and 559 are stabilized. These two tests were initially introduced
  to aid in the location of a seg-fault which was only triggered on non-debug
  builds done with the icc 9.1 Intel compiler. Test 558 does not trigger the
  problem, but test 559 does trigger it. As of today, it isn't yet absolutely
  clear if it is a compiler optimizer issue or a memory corruption one.

Yang Tse (30 Oct 2008)
- Use our Curl_addrinfo structure definition to handle address info data even
  when a system addrinfo struct is available. Provide and use a wrapper around
  systems getaddrinfo function, Curl_getaddrinfo_ex which returns a pointer to
  a list of dynamically allocated Curl_addrinfo structs.

  Configure will check freeaddrinfo and getaddrinfo functions and define
  preprocessor symbols HAVE_FREEADDRINFO and HAVE_GETADDRINFO when appropriate.

Daniel Fandrich (29 Oct 2008)
- Fixed a bug that caused a few bytes of garbage to be sent after a
  curl_easy_pause() during a chunky upload. Reported by Steve Roskowski.

Daniel Fandrich (28 Oct 2008)
- Changed the "resolve" test precheck program to verify that an IPv6 socket
  can be created before resolving the IPv6 name.  In the context of running
  a test, it doesn't make sense to run an IPv6 test when a host is resolvable
  but IPv6 isn't usable.  This should fix failures of test 1085 on hosts with
  library and DNS support for IPv6 but where actual use of IPv6 has been
  administratively disabled.

Daniel Fandrich (24 Oct 2008)
- Added experimental support for zlib and OpenSSL on Symbian OS.

Daniel Fandrich (21 Oct 2008)
- Fixed some problems with SFTP range support to fix test cases 634 through
  637.

Daniel Fandrich (17 Oct 2008)
- Fixed a compile error reported by Albert Chin on AIX and IRIX when using
  GTLS.

Daniel Stenberg (16 Oct 2008)
- Igor Novoseltsev added CURLOPT_PROXYUSER and CURLOPT_PROXYPASSWORD that then
  make CURLOPT_PROXYUSERPWD sort of deprecated. The primary motive for adding
  these new options is that they have no problems with the colon separator
  that the CURLOPT_PROXYUSERPWD option does.

Daniel Stenberg (15 Oct 2008)
- Pascal Terjan filed bug #2154627
  (http://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl
  uses strcasecmp() in multiple places where it causes failures when the
  Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
  strcasecmp() on those letters are different in Turkish than in English (or
  just about all other languages). I thus introduced a totally new internal
  function in libcurl (called Curl_raw_equal) for doing case insentive
  comparisons for english-(ascii?) style strings that thus will make "file"
  and "FILE" match even if the Turkish locale is selected.

Daniel Fandrich (15 Oct 2008)
- A <precheck> command is considered to have failed if it returns a non-zero
  return code.  This way, if the precheck command can't be run at all for
  whatever reason, it's treated as a precheck failure which causes the
  test to be skipped.

Daniel Stenberg (15 Oct 2008)
- John Wilkinson filed bug #2155496
  (http://curl.haxx.se/bug/view.cgi?id=2155496) pointing out an error case
  without a proper human-readable error message. When a read callback returns
  a too large value (like when trying to return a negative number) it would
  trigger and the generic error message then makes the proplem slightly
  different to track down. I've added an error message for this now.

Daniel Fandrich (9 Oct 2008)
- Fixed the --interface option to work with IPv6 connections on glibc
  systems supporting getifaddrs(). Also fixed a problem where an IPv6
  address could be chosen instead of an IPv4 one for --interface when it
  involved a name lookup.

Daniel Fandrich (8 Oct 2008)
- Added tests 1082 through 1085 to test symbolic --interface parameters

- Added tests 633 through 637 to test the new file range support for SFTP.
  All but the first test cause an infinite loop or other failure and so
  are added to DISABLED.

Daniel Stenberg (8 Oct 2008)
- John Wilkinson filed bug #2152270
  (http://curl.haxx.se/bug/view.cgi?id=2152270) which identified and fixed a
  CURLINFO_REDIRECT_URL memory leak and an additional wrong-doing:

  Any subsequent transfer with a redirect leaks memory, eventually crashing
  the process potentially.

  Any subsequent transfer WITHOUT a redirect causes the most recent redirect
  that DID occur on some previous transfer to still be reported.

- Igor Novoseltsev filed bug #2111613
  (http://curl.haxx.se/bug/view.cgi?id=2111613) that eventually identified a
  flaw in how the multi_socket interface in some cases missed to call the
  timeout callback when easy interfaces are removed and added within the same
  millisecond.

- Igor Novoseltsev brought a patch that introduced two new options to
  curl_easy_setopt: CURLOPT_USERNAME and CURLOPT_PASSWORD that sort of
  deprecates the good old CURLOPT_USERPWD since they allow applications to set
  the user name and password independently and perhaps more importantly allow
  both to contain colon(s) which CURLOPT_USERPWD doesn't fully support.

Daniel Fandrich (7 Oct 2008)
- Changed the handling of read/write errors in Curl_perform() to allow a
  a fresh connection to be made in such cases and the request retransmitted.
  This should fix test case 160.  Added test case 1079 in an attempt to
  test a similar connection dropping scenario, but as a race condition, it's
  hard to test reliably.

- Created test cases 1080 and 1081 to reproduce a problem of
  CURLINFO_REDIRECT_URL leaking memory and returning incorrect results when
  two URLs are requested. Reported by vmpdemo in bug #2152270

Daniel Stenberg (7 Oct 2008)
- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then
  the app re-used the handle to do a connection to host B and then again
  re-used the handle to host A, it would not update the info with host A's IP
  address (due to the connection being re-used) but it would instead report
  the info from host B.

Yang Tse (7 Oct 2008)
- Added --enable-optimize configure option to enable and disable compiler
  optimizations to allow decoupled setting from --enable-debug.

Yang Tse (2 Oct 2008)
- Added --enable-warnings configure option to enable and disable strict
  compiler warnings to allow decoupled setting from --enable-debug.

  runtests.pl will now run with picky compiler warnings enabled unless
  explicitly disabled.

Daniel Fandrich (1 Oct 2008)
- "make clean" now cleans out the docs and tests directories, too.

Daniel Stenberg (30 Sep 2008)
- The libcurl FTP code now returns CURLE_REMOTE_FILE_NOT_FOUND error when SIZE
  gets a 550 response back for the cases where a download (or NOBODY) is
  wanted. It still allows a 550 as response if the SIZE is used as part of an
  upload process (like if resuming an upload is requested and the file isn't
  there before the upload). I also modified the FTP test server and a few test
  cases accordingly to match this modified behavior.

Daniel Stenberg (29 Sep 2008)
- Daniel Egger provided a patch that allows you to disable proxy support in
  libcurl to somewhat reduce the size of the binary. Run configure
  --disable-proxy.

Daniel Fandrich (29 Sep 2008)
- Moved all signal-based name resolution timeout handling into a single new
  Curl_resolv_timeout function to reduce coupling.

Daniel Stenberg (29 Sep 2008)
- Ian Lynagh provided a patch that now makes CURLOPT_RANGE work fine for SFTP
  downloads!

- Maxim Ivanov filed bug report #2107803
  (http://curl.haxx.se/bug/view.cgi?id=2107803) "no CURLINFO_REDIRECT_URL in
  multi mode" together with a patch that fixed the problem.

Daniel Stenberg (25 Sep 2008)
- Emanuele Bovisio submitted bug report #2126435. We fixed the HTTP Digest
  auth code to not behave badly when getting a blank realm with
  realm="". http://curl.haxx.se/bug/view.cgi?id=2126435

Daniel Fandrich (23 Sep 2008)
- Make sure not to dereference the wrong UrlState proto union member when
  switching from one protocol to another in a single request (e.g.
  redirecting from HTTP to FTP as in test 1055) by resetting
  state.expect100header before every request.

Daniel Stenberg (23 Sep 2008)
- Introducing Jamie Lokier's function for date to epoch conversion used in the
  date parser function. This makes our function less dependent on system-
  provided functions and instead we do all the magic ourselves. We also no
  longer depend on the TZ environment variable. Switching to our own converter
  has some side-effect and they are noted here for future reference (taken
  from a mail by mr Lokier):

  time_t is not measured in seconds in the ANSI C standard - or even counted
  uniformly - weird platforms can use other numeric representations of dates
  in time_t - hence the difftime() function.

  On POSIX time_t is measured in UTC seconds, which means not including leap
  seconds.  But it's mentioned in a few places that some old POSIX-ish
  environments include leap seconds in their time_t counts...

  I'm pretty sure [the new implementation is] correct on anything truly POSIX.
  And it's obviously a lot less dependent on platform quirks and corner cases
  in many ways than the mktime() version.

- Rob Crittenden brought a patch to "add some locking for thread-safety to NSS
  implementation".

Daniel Stenberg (22 Sep 2008)
- Made the SOCKS code use the new Curl_read_plain() function to fix the bug
  Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html

- recv() errors other than those equal to EAGAIN now cause proper
  CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
  disabled it until we can figure out another way to exercise that logic.

- Michael Goffioul filed bug report #2107377 "Problem with multi + GnuTLS +
  proxy" (http://curl.haxx.se/bug/view.cgi?id=2107377) that showed how a multi
  interface using program didn't work when built with GnuTLS and a CONNECT
  request was done over a proxy (basically test 502 over a proxy to a HTTPS
  site). It turned out the ssl connect function would get called twice which
  caused the second call to fail.

Daniel Fandrich (22 Sep 2008)
- Fixed test 539 to handle an out of memory condition that shows up now
  that memdebug.h is included in the test programs.

Yang Tse (20 Sep 2008)
- Fix regression in configure script which affected OpenSSL builds on MSYS.

Yang Tse (19 Sep 2008)
- configure script now checks availability of the alarm() function.

Daniel Fandrich (18 Sep 2008)
- Don't bother to install a SIGALRM handler unless alarm() is available.
  Also, leave the existing SIGALRM handler alone if the timeout is too small
  to handle.

Daniel Fandrich (17 Sep 2008)
- Removed reference to curl-ca-bundle.crt in the host verification failure
  error message.

Yang Tse (17 Sep 2008)
- Improve configure detection of gethostname(), localtime_r(), strstr(),
  getservbyport_r(), gethostbyaddr_r() and gethostbyname_r().

Yang Tse (14 Sep 2008)
- Improve configure detection of strcasecmp(), strcasestr(), strcmpi(),
  stricmp(), strlcat(), strncasecmp(), strncmpi() and strnicmp().

Yang Tse (13 Sep 2008)
- Disable tracking of fdopen() calls in the low-level memory leak tracking
  code when fdopen() is not available, to avoid compiler error.

Yang Tse (12 Sep 2008)
- Further adjust detection of strerror_r() in the configure process, and
  ensure that errno is not modified inside Curl_strerror().

Yang Tse (10 Sep 2008)
- Improve detection of gmtime_r(), strtoll(), sigaction(), strtok_r(),
  strdup() and ftruncate() in the configure process.

Daniel Fandrich (9 Sep 2008)
- Mike Revi discovered some swapped speed switches documented in the curl man
  page.

- Checked in some documentation and code improvements and fixes that I
  discovered in the FreeBSD ports system.

Daniel Stenberg (8 Sep 2008)
- Dmitry Kurochkin patched a problem: I have found bug in pipelining through
  proxy. I have a transparent proxy. When running with http_proxy environment
  variable not set my test completes fine (it goes through transparent
  proxy). When I set http_proxy variable my test hangs after the first
  downloaded is complete. Looks like the second handle never gets out from
  WAITDO state.

  The fix: It makes checkPendPipeline move 1 handler from pend pipe to send
  pipe if pipelining is not supported by server but there are no handles in
  send and recv pipes.

- Stefan Krause pointed out that libcurl would wrongly send away cookies to
  sites in cases where the cookie clearly has a very old expiry date. The
  condition was simply that libcurl's date parser would fail to convert the
  date and it would then count as a (timed-based) match. Starting now, a
  missed date due to an unsupported date format or date range will now cause
  the cookie to not match.

Daniel Fandrich (5 Sep 2008)
- Improved the logic that decides whether to use HTTP 1.1 features or not in a
  request.  Setting a specific version with CURLOPT_HTTP_VERSION overrides
  all other checks, but otherwise, a 1.0 request will be made if the server
  is known to support only 1.0 because it previously responded so and the
  connection was kept alive, or a response to a previous request on this handle
  came back as 1.0. The latter could take place in cases like redirection or
  authentication where several requests have to be made before the operation
  is complete.  If any one of the servers in a redirection chain supports only
  1.0, then remaining requests will be sent in 1.0 mode.

- Detect cases where an upload must be sent chunked and the server supports
  only HTTP 1.0 and return CURLE_UPLOAD_FAILED.

Daniel Stenberg (5 Sep 2008)
- Martin Drasar provided the CURLOPT_POSTREDIR patch. It renames
  CURLOPT_POST301 (but adds a define for backwards compatibility for you who
  don't define CURL_NO_OLDIES). This option allows you to now also change the
  libcurl behavior for a HTTP response 302 after a POST to not use GET in the
  subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
  patch somewhat before commit. The curl tool got a matching --post302
  option. Test case 1076 was added to verify this.

- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. By
  enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
  or FTPS), libcurl will gather lots of server certificate info and that info
  can then get extracted by a client after the request has completed with
  curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
  helped me test and smoothen out this feature.

  Unfortunately, this feature currently only works with libcurl built to use
  OpenSSL.

  This feature was sponsored by networking4all.com - thanks!

- Dmitriy Sergeyev pointed out that curl_easy_pause() didn't unpause properly
  during certain conditions. I also changed this code to use realloc() based
  on Daniel Fandrich's suggestion.

Guenter Knauf (4 Sep 2008)
- MingW32 non-configure builds are now largefile feature enabled by default.
  NetWare LIBC builds are also now largefile feature enabled by default.

Yang Tse (4 Sep 2008)
- Several fixes related with print formatting string directives.

Daniel Fandrich (3 Sep 2008)
- Search for the FreeBSD CA cert file /usr/local/share/certs/ca-root.crt

Daniel Fandrich (2 Sep 2008)
- Fixed an out of memory problem that caused torture test failures in tests
  706 and 707.

Daniel Stenberg (2 Sep 2008)
- Keith Mok added supported_protocols and supported_features to the pkg-config
  file for libcurl, and while doing that fix he unified with curl-config.in
  how the supported protocols and features are extracted and used, so both those
  tools should now always be synced.

Version 7.19.0 (1 September 2008)

Daniel Fandrich (29 Aug 2008)
- Added tests 1071 through 1074 to test automatic downgrading from HTTP 1.1
  to HTTP 1.0 upon receiving a response from the HTTP server.  Tests 1072
  and 1073 are similar to test 1069 in that they involve the impossible
  scenario of sending chunked data to a HTTP 1.0 server.  All these fail
  and are added to DISABLED.

- Added test 1075 to test --anyauth with Basic authentication.

Daniel Stenberg (29 Aug 2008)
- When libcurl was doing a HTTP POST and the server would respond with
  "Connection: close" and actually close the connection after the
  response-body, libcurl could still have outstanding data to send and it
  would not properly notice this and stop sending. This caused weirdness and
  sad faces. http://curl.haxx.se/bug/view.cgi?id=2080222

  Note that there are still reasons to consider libcurl's behavior when
  getting a >= 400 response code while sending data, as Craig Perras' note
  "http upload: how to stop on error" specifies:
  http://curl.haxx.se/mail/archive-2008-08/0138.html

Daniel Stenberg (28 Aug 2008)
- Dengminwen reported that libcurl would lock a (cookie) share twice (without
  an unlock in between) for a certain case and that in fact works when using
  regular windows mutexes but not with pthreads'! Locks should of course not
  get locked again so this is now fixed.
  http://curl.haxx.se/mail/lib-2008-08/0422.html

- I'm abandoning the system with the web site mirrors (but keeping download
  files bing mirrored) and thus I've changed the URL in the cookiejar header
  to no longer use curlm.haxx.se but instead use the main site curl.haxx.se

Daniel Fandrich (27 Aug 2008)
- Fixed test case 1065 by changing the handling of CURLOPT_UPLOAD to set
  the HTTP method to GET (or HEAD) when given a value of 0.

- Added test cases 1068 and 1069 to test a simple HTTP PUT from stdin.  Test
  case 1069 fails in a similar manner to test 1065 so is added to DISABLED.

Yang Tse (27 Aug 2008)
- Fix generation of MS VC6 .dsp file to make it support compilation of either
  dynamic (DLL) or static (LIB) libcurl libraries in debug and release modes.

Daniel Fandrich (26 Aug 2008)
- Fixed out of memory problems that caused torture test failures in tests
  1021 and 1067.

Yang Tse (26 Aug 2008)
- Added check and symbol definition for WIN32 file API usage in configure,
  supporting configure's --disable-largefile option for WIN32 targets also.

- Non-configure systems which do not use config-win32.h configuration file,
  and want to use the WIN32 file API, must define USE_WIN32_LARGE_FILES or
  USE_WIN32_SMALL_FILES as appropriate in their own configuration files.

Daniel Stenberg (23 Aug 2008)
- Running 'make ca-firefox' in the root build dir will now run the new
  firefox-db2pem.sh conversion script that converts a local Firefox db of ca
  certs into PEM format, suitable for use with a OpenSSL or GnuTLS built
  libcurl.

- Constantine Sapuntzakis fixed a bug when doing proxy CONNECT with the multi
  interface, and the proxy would send Connection: close during the
  authentication phase.  http://curl.haxx.se/bug/view.cgi?id=2069047

Daniel Fandrich (22 Aug 2008)
- Fixed a problem when --dump-header - was given with more than one URL,
  which caused an error when the second header was dumped due to stdout
  being closed.  Added test case 1066 to verify.  Also fixed a potential
  problem where a closed file descriptor might be used for an upload
  when more than one URL is given.

Yang Tse (22 Aug 2008)
- Improved libcurl's internal curl_m*printf() functions integral data type
  size and signedness handling.

- Internal adjustments to better select/differentiate when large/small file
  support is provided using WIN32 functions directly.

Daniel Fandrich (20 Aug 2008)
- Added an edited version of Vincent Le Normand's documentation of SFTP quote
  commands to the man pages.

Daniel Stenberg (20 Aug 2008)
- Phil Pellouchoud pointed out that the windows version of libcurl had a
  memory leak because it never called the OpenSSL function
  CRYPTO_cleanup_all_ex_data() as it was supposed to. This was because of a
  missing define in config-win32.h!

Gisle Vanem (18 Aug 2008)
- Updated lib/Makefile.Watcom with the option to use c-ares (USE_ARES=1).

Yang Tse (18 Aug 2008)
- Added test case 557 to verify libcurl's internal curl_m*printf() functions
  formatting functionality when handling signed and unsigned longs, as well as
  our curl_off_t data type.

Yang Tse (17 Aug 2008)
- OpenSSl enabled NetWare builds are changed to use the 'openssl' subdirectory
  when including the OpenSSL header files. This is the recommended setting, this
  prevents the undesired inclusion of header files with the same name as those
  of OpenSSL but which do not belong to the OpenSSL package. The visible change
  from previously released libcurl versions is that now OpenSSl enabled NetWare
  builds also define USE_OPENSSL in config files, and that OpenSSL header files
  must be located in a subdirectory named 'openssl'.

Yang Tse (16 Aug 2008)
- Library internal only C preprocessor macros FORMAT_OFF_T and FORMAT_OFF_TU
  remain in use as internal curl_off_t print formatting strings for the internal
  *printf functions which still cannot handle print formatting string directives
  such as "I64d", "I64u", and others available on MSVC, MinGW, Intel's ICC, and
  other DOS/Windows compilers.

Daniel Fandrich (15 Aug 2008)
- Added test case 1063 to test invalid long file ranges with file: URLs and
  1064 to test multiple http PUTs.

- Added test case 1065 to test a PUT with a single file but two URLs. This
  was discovered to be problematic while investigating an incident reported by
  Von back in May.  curl in this case doesn't include a Content-Length: or
  Transfer-Encoding: chunked header which is illegal. This test case is
  added to DISABLED until a solution is found.

Yang Tse (15 Aug 2008)
- C preprocessor macros used internally and equally available externally which
