                                  Changelog

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

Daniel Stenberg (8 Oct 2008)
- Bug #2152270 (http://curl.haxx.se/bug/view.cgi?id=2152270) 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 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
