                                  Changelog

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.

Yang Tse (17 Jan 2008)
- Don't abort tests 518 and 537 when unable to raise the open-file soft limit.

Daniel S (16 Jan 2008)
- Nathan Coulter's patch that makes runtests.pl respect the PATH when figuring
  out what valgrind to run.

Yang Tse (16 Jan 2008)
- Improved handling of out of memory in the command line tool that afected
  data url encoded HTTP POSTs when reading it from a file.

Daniel S (16 Jan 2008)
- Dmitry Kurochkin worked a lot on improving the HTTP Pipelining support that
  previously had a number of flaws, perhaps most notably when an application
  fired up N transfers at once as then they wouldn't pipeline at all that
  nicely as anyone would think... Test case 530 was also updated to take the
  improved functionality into account.

- Calls to Curl_failf() are not supposed to provide a trailing newline as the
  function itself adds that. Fixed on 50 or something strings!

Daniel S (15 Jan 2008)
- I made the torture test on test 530 go through. This was actually due to
  silly code left from when we switched to let the multi handle "hold" the dns
  cache when using the multi interface... Of course this only triggered when a
  certain function call returned error at the correct moment.

Daniel S (14 Jan 2008)
- Joe Malicki filed bug report #1871269
  (http://curl.haxx.se/bug/view.cgi?id=1871269) and we could fix his hang-
  problem that occurred when doing a large HTTP POST request with the
  response-body read from a callback.

Daniel S (12 Jan 2008)
- I re-arranged the curl --help output. All the options are now sorted on
  their long option names and all descriptions are one-liners.

- Eric Landes provided the patch (edited by me) that introduces the
  --keepalive-time to curl to set the keepalive probe interval. I also took
  the opportunity to rename the recently added no-keep-alive option to
  no-keepalive to keep a consistent naming and to avoid getting two dashes in
  these option names. Eric also provided an update to the man page for the new
  option.

Daniel S (11 Jan 2008)
- Daniel Egger made CURLOPT_RANGE work on file:// URLs the very same way it
  already worked for FTP:// URLs.

- I made the curl tool switch from using CURLOPT_IOCTLFUNCTION to now use the
  spanking new CURLOPT_SEEKFUNCTION simply to take advantage of the improved
  performance for the upload resume cases where you want to upload the last
  few bytes of a very large file. To implement this decently, I had to switch
  the client code for uploading from fopen()/fread() to plain open()/read() so
  that we can use lseek() to do >32bit seeks (as fseek() doesn't allow that)
  on systems that offer support for that.

Daniel S (10 Jan 2008)
- Michal Marek made curl-config --libs not include /usr/lib64 in the output
  (it already before skipped /usr/lib).  /usr/lib64 is the default library
  directory on many 64bit systems and it's unlikely that anyone would use the
  path privately on systems where it's not.

- Georg Lippitsch brought CURLOPT_SEEKFUNCTION and CURLOPT_SEEKDATA to allow
  libcurl to seek in a given input stream. This is particularly important when
  doing upload resumes when there's already a huge part of the file present
  remotely. Before, and still if this callback isn't used, libcurl will read
  and through away the entire file up to the point to where the resuming
  begins (which of course can be a slow opereration depending on file size,
  I/O bandwidth and more). This new function will also be preferred to get
  used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
  doing multi-stage HTTP auth with POST/PUT.

- Nikitinskit Dmitriy filed bug report #1868255
  (http://curl.haxx.se/bug/view.cgi?id=1868255) with a patch. It identifies
  and fixes a problem with parsing WWW-Authenticate: headers with additional
  spaces in the line that the parser wasn't written to deal with.

Daniel S (8 Jan 2008)
- Introducing curl_easy_pause() and new magic return codes for both the read
  and the write callbacks that now can make a connection's reading and/or
  writing get paused.

Daniel S (6 Jan 2008)
- Jeff Johnson filed bug report #1863171
  (http://curl.haxx.se/bug/view.cgi?id=1863171) where he pointed out that
  libcurl's date parser didn't accept a +1300 time zone which actually is used
  fairly often (like New Zealand's Dailight Savings Time), so I modified the
  parser to now accept up to and including -1400 to +1400.

Daniel S (5 Jan 2008)
- Based on further discussion on curl-library, I reverted yesterday's SOCKS5
  code to instead introduce support for a new proxy type called
  CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
  instead of IP address and there's thus no longer any need for a new
  curl_easy_setopt() option.

  The default SOCKS5 proxy is again back to sending the IP address to the
  proxy.  The new curl command line option for enabling sending host name to a
  SOCKS5 proxy is now --socks5-hostname.

Daniel S (4 Jan 2008)
- Based on Maxim Perenesenko's patch, we now do SOCKS5 operations and let the
  proxy do the host name resolving and only if --socks5ip (or
  CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
  pass on the IP address only to the proxy.

Yang Tse (3 Jan 2008)
- Modified test harness to allow SCP, SFTP and SOCKS4 tests to run with
  OpenSSH 2.9.9, SunSSH 1.0 or later versions. SOCKS5 tests need OpenSSH
  3.7, SunSSH 1.0 or later.

Daniel S (2 Jan 2008)
- I fixed two cases of missing return code checks when handling chunked
  decoding where a write error (or abort return from a callback) didn't stop
  libcurl's processing.

- I removed the socklen_t use from the public curl/curl.h header and instead
  made it an unsigned int. The type was only used in the curl_sockaddr struct
  definition (only used by the curl_opensocket_callback). On all platforms I
  could find information about, socklen_t is 32 unsigned bits large so I don't
  think this will break the API or ABI. The main reason for this change is of
  course for all the platforms that don't have a socklen_t definition in their
  headers to build fine again. Providing our own configure magic and custom
  definition of socklen_t on those systems proved to work but was a lot of
  cruft, code and extra magic needed - when this very small change of type
  seems harmless and still solves the missing socklen_t problem.

- Richard Atterer brought a patch that added support for SOCKS4a proxies,
  which is an inofficial PROXY4 variant that sends the hostname to the proxy
  instead of the resolved address (which is already supported by SOCKS5).
  --socks4a is the curl command line option for it and CURLOPT_PROXYTYPE can
  now be set to CURLPROXY_SOCKS4A as well.

Daniel S (1 Jan 2008)
- Mohun Biswas pointed out that --libcurl generated a source code with an int
  function but without a return statement. While fixing that, I also took care
  about adding some better comments for the generated code.

Daniel S (27 Dec 2007)
- Dmitry Kurochkin mentioned a flaw
  (http://curl.haxx.se/mail/lib-2007-12/0252.html) in detect_proxy() which
  failed to set the bits.proxy variable properly when an environment variable
  told libcurl to use a http proxy.

Daniel S (26 Dec 2007)
- In an attempt to repeat the problem in bug report #1850730
  (http://curl.haxx.se/bug/view.cgi?id=1850730) I wrote up test case 552. The
  test is doing a 70K POST with a read callback and an ioctl callback over a
  proxy requiring Digest auth. The test case code is more or less identical to
  the test recipe code provided by Spacen Jasset (who submitted the bug
  report).

Daniel S (25 Dec 2007)
- Gary Maxwell filed bug report #1856628
  (http://curl.haxx.se/bug/view.cgi?id=1856628) and provided a fix for the
  (small) memory leak in the SSL session ID caching code. It happened when a
  previous entry in the cache was re-used.

Daniel Fandrich (19 Dec 2007)
- Ensure that nroff doesn't put anything but ASCII characters into the
  --manual text.

Yang Tse (18 Dec 2007)
- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
  and makes wrong asumptions of build target when it isn't specified. So,
  if no build target has been defined we will target WinXP when building
  curl/libcurl with MSVC 9.0 (VS2008).

- (http://curl.haxx.se/mail/archive-2007-12/0039.html) reported and fixed
  a file truncation problem on Windows build targets triggered when retrying
  a download with curl.

Daniel S (17 Dec 2007)
- Mateusz Loskot pointed out that MSVC 9.0 (VS2008) has the pollfd struct and
  defines in winsock2.h somehow differently than previous versions and that
  curl 7.17.1 would fail to compile out of the box.

Daniel S (13 Dec 2007)
- David Wright filed bug report #1849764
  (http://curl.haxx.se/bug/view.cgi?id=1849764) with an included fix. He
  identified a problem for re-used connections that previously had sent
  Expect: 100-continue and in some situations the subsequent POST (that didn't
  use Expect:) still had the internal flag set for its use. David's fix (that
  makes the setting of the flag in every single request unconditionally) is
  fine and is now used!
