                                  Changelog

Daniel Fandrich (7 Aug 2008)
- Fixed an uninitialized variable in multi_runsingle() that could cause a
  request to prematurely end.

Yang Tse (7 Aug 2008)
- Added curlbuild.h and curlrules.h header files to libcurl's public headers.
  File curlbuild.h is a generated file on configure-capable systems. This is
  a first step towards configure-based info in public headers. Currently only
  used to provide support for a curl_off_t data type which is not gated to
  off_t. Further details are documented inside these mentioned header files.

- Fix CURL_CHECK_DEF so that when the expansion of the preprocessor symbol
  results in a set of double-quoted strings, this macro will now return an
  expansion which consists of a single double-quoted string as the result of
  concatenating all of them.

- Skip data type check in DO_CURL_OFF_T_CHECK macro when argument is empty.

- Adjusted testcurl.pl to copy checked out curlbuild.h.dist as curlbuild.h
  for non-configure targets when the host system doesn't run buildconf.bat.

- Prevent buildconf from removing 'Makefile' and 'missing' files. This would
  blow away our CVS checked files 'missing' and 'hiper/Makefile'.

- Remove adjustment done to testcurl.pl to verify if change introduced by
  Guenter Knauf in lib/Makefile.netware is enough to get the netware autobuilds
  going again.

Yang Tse (5 Aug 2008)
- Changes done to buildconf script. Validate that autom4te and autoconf, as
  well as aclocal and automake, versions match. Improve removal of previous
  run generated files. Remove verbose debug logging of aclocal on Solaris.

Daniel Stenberg (5 Aug 2008)
- Yehoshua Hershberg found a problem that would make libcurl re-use a
  connection with the multi interface even if a previous use of it caused a
  CURLE_PEER_FAILED_VERIFICATION to get returned. I now make sure that failed
  SSL connections properly close the connections.

Daniel Stenberg (4 Aug 2008)
- Test cases 1051, 1052 and 1055 were added by Daniel Fandrich on July 30 and
  proved how PUT and POST with a redirect could lead to a "hang" due to the
  data stream not being rewound properly when it had to in order to get sent
  properly (again) to the subsequent URL. This is now fixed and these test
  cases are no longer disabled.

Yang Tse (4 Aug 2008)
- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
  Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
  version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
  no matter if the system is AIX or not. To keep the traditional behaviour,
  and an uniform one across autoconf versions AC_AIX is replaced with our
  own internal macro CURL_CHECK_AIX_ALL_SOURCE.

Daniel Stenberg (4 Aug 2008)
- Test case 1041 (added by Daniel Fandrich July 14th) proved a bug where PUT
  with -C - sent garbage in the Content-Range: header. I fixed this problem by
  making sure libcurl always sets the size of the _entire_ upload if an app
  attemps to do resumed uploads since libcurl simply cannot know the size of
  what is currently at the server end. Test 1041 is no longer disabled.

Yang Tse (2 Aug 2008)
- No longer test availability of the gdi32 library, nor use it for linking, even
  when we have been doing this since revision 1.47 of configure.ac 4 years and
  5 months ago when cross-compiling a Windows target. We actually don't use any
  function from the Windows GDI (Graphics Device Interface) related with drawing
  or graphics-related operations.

Daniel Fandrich (1 Aug 2008)
- Added support for --append on SFTP uploads. Unfortunately, OpenSSH doesn't
  support this so it goes untested.

Yang Tse (1 Aug 2008)
- Configure process now checks if the preprocessor _REENTRANT symbol is already
  defined. If it isn't currently defined a set of checks are performed to test
  if its definition is required to make visible to the compiler a set of *_r
  functions. Finally, if _REENTRANT is already defined or needed it takes care
  of making adjustments necessary to ensure that it is defined equally for the
  configure process tests and generated config file.

- Removed definition of CURL_CHECK_WORKING_RESOLVER from acinclude.m4 it has
  not been in use since revision 1.81 of configure.in 6 years, 9 months ago.

Daniel Fandrich (31 Jul 2008)
- Fixed parsing of an IPv6 proxy address to support a scope identifier,
  as well as IPv4 addresses in IPv6 format. Also, better handle the case
  of a malformatted IPv6 address (avoid empty and NULL strings).

- Fixed a problem with any FTP URL or any URLs containing an IPv6 address
  being mangled when passed to proxies when CURLOPT_PORT is also set
  (reported by Pramod Sharma).

- User names embedded in proxy URLs without a password were parsed
  incorrectly--the host name is treated as part of the user name and the
  port number becomes the password.  This can be observed in test 279
  (was KNOWN_ISSUE #54).

Daniel Stenberg (30 Jul 2008)
- Phil Blundell added the CURLOPT_ADDRESS_SCOPE option, as well as adjusted
  the URL parser to allow numerical IPv6-addresses to be specified with the
  scope given, as per RFC4007 - with a percent letter that itself needs to be
  URL escaped. For example, for an address of fe80::1234%1 the HTTP URL is:
  "http://[fe80::1234%251]/"

- PHP's bug report #43158 (http://bugs.php.net/bug.php?id=43158) identifies a
  true bug in libcurl built with OpenSSL. It made curl_easy_getinfo() more or
  less always return 0 for CURLINFO_SSL_VERIFYRESULT because the function that
  would set it to something non-zero would return before the assign in almost
  all error cases. The internal variable is now set to non-zero from the start
  of the function only to get cleared later on if things work out fine.

- Made the curl tool's -w option support the %{ssl_verify_result} variable

Daniel Fandrich (30 Jul 2008)
- Added test cases 1052 through 1055 to test uploading data from files
  during redirects.  Test cases 1052 and 1055 show problems (maybe the same
  root cause as 1051) and are disabled.

- Fixed a couple of buffer overflows in the MS-DOS port of the curl tool.

Daniel Fandrich (29 Jul 2008)
- Fixed --use-ascii to properly convert text files on Symbian OS, MS-DOS
  and OS/2.

- Added test case 1051 to test Location: following with PUT, as reported
  by Ben Sutcliffe.  The test when run manually shows a problem in curl
  so it's disabled.

Daniel Fandrich (28 Jul 2008)
- Fixed display of the interface bind address in the trace output when it's
  an IPv6 address.

- Added test cases 1045 through 1049 as simple tests of --interface using the
  localhost interface.

- Added test case 1050 to test --ftp-port with an IPv6 address

Daniel Stenberg (26 Jul 2008)
- David Bau filed bug report #2026240 "CURL_READFUNC_PAUSE leads to buffer
  overrun" (http://curl.haxx.se/bug/view.cgi?id=2026240) identifying two
  problems, and providing the fix for them:

  - CURL_READFUNC_PAUSE did in fact not pause the _sending_ of data that it is
    designed for but paused _receiving_ of data!

  - libcurl didn't internally set the read counter to zero when this return
    code was detected, which would potentially lead to junk getting sent to
    the server.

Daniel Fandrich (26 Jul 2008)
- Added test 1044 to test large file support in ftp with -I.

- Eliminate a unnecessary socket creation in Curl_getaddrinfo for an IPv4
  address in an IPv6 capable libcurl.

- Added feature in runtests.pl to select tests based on key word.

Daniel Fandrich (23 Jul 2008)
- Changed the long logfile elision code in runtests.pl to properly handle
  lines ending in \r.

- Changed references to TRUE and FALSE in the curl_easy_setopt man page to
  1 and zero, respectively, since TRUE and FALSE aren't part of the
  libcurl API.

Daniel Stenberg (23 Jul 2008)
- I went over the curl_easy_setopt man page and replaced most references to
  non-zero with the fixed value of 1. We should strive at making options
  support '1' for enabling them mentioned explicitly, as that then will allow
  us for to extend them in the future without breaking older programs.

  Possibly we should even introduce a fancy define to use instead of '1' all
  over...

Yang Tse (21 Jul 2008)
- Use the sreadfrom() wrapper to replace recvfrom() in our code.

Yang Tse (20 Jul 2008)
- when recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
  now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.

Yang Tse (17 Jul 2008)
- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
  to the data type pointed by its respective argument and not the pointer type.

Yang Tse (16 Jul 2008)
- Configure process now checks availability of recvfrom() socket function and
  finds out its return type and the types of its arguments. Added definitions
  for non-configure systems config files, and introduced macro sreadfrom which
  will be used on udp sockets as a recvfrom() wrapper.
