                               History of Changes

Daniel (28 May 2001)
- curl-config now supports '--vernum' that outputs a plain hexadecimal version
  of the libcurl version number (using 8 bits for each 3 numbers). Version
  7.7.4 appears as 070704

- Wrote man pages for curl_global_init and curl_global_cleanup...

- T. Bharath brought news about the usage of the OpenSSL interface that was
  not previously taken into consideration and thus caused libcurl to leak
  memory.  The only somewhat sane approach to fix this dilemma, is adding two
  two new functions curl_global_init() and curl_global_cleanup() that should
  be called *ONCE* by the application using libcurl. The init should be done
  only at startup, no matter how many threads the application is gonna use,
  and the cleanup should be called when the application has finished using
  libcurl completely.

  *** UPGRADE NOTICE ***

  If you write applications using libcurl, you really want to use two
  functions mentioned above !!!

  I can't say I think this is a very beautiful solution, but as OpenSSL
  insists on making lots of stuff on a "global" scope, we're forced to dance
  to their pipe.

- Moving more test cases into the new file format.

Version 7.7.4-pre3

Daniel (23 May 2001)
- Introduced a new file format for storing test cases, and thus I had to
  modify all the perl test scripts and more (I added a new one). I have not
  "ported" all the old test cases to the new format yet, but it'll come.

  The main advantage of this new format is that all test data for each test
  case is stored in a single file. It gives a better overview for each test
  case and a lot less files.

- Andrés García brought a fix for the netscape/mozilla cookie file parsing
  function, as it turns out it doesn't always store the path!

Daniel (22 May 2001)
- As was reported anonymously, when FAILONERROR was used, the httpcode was
  not stored properly and thus wasn't possibly to read after a transfer with
  the curl_easy_getinfo() function. This is now corrected.

- Installed and made use of the following tool versions:
    autoconf 2.50
    libtool 1.4
    automake 1.4-p1

  I wouldn't recommend any developer to try to generate things with older
  versions than these. Building from CVS will probably more or less require
  at least these versions.

  As a result of this, the configure script grew to more than double its
  previous size!

  Arkadiusz Miskiewicz helped me by pointing out I had to remove my
  acinclude.m4 file before I could get it working!

Daniel (21 May 2001)
- I made ftps:// work. Added test case 400 to the release archive, as the
  first ftps:// test case. Requires stunnel.

- Also made the test cases that runs ssl tests not run if libcurl isn't built
  with ssl support.

Daniel (19 May 2001)
- Made the configure not add any extra -L LDFLAGS or -I CPPFLAGS unless they
  are actually needed. Albert Chin's and Domenico Andreoli's suggestions
  helped out.

Version 7.7.4-pre2

Daniel (18 May 2001)
- Nicer configure-check for the OpenSSL headers, which then sets the proper
  variable to have curl-config be good. (Albert Chin provided the fix)

- For systems that don't have theiw own 'strlcat()' libcurl provides its own.
  It was now renamed to prevent collides with other libs. (After discussions
  with Sterling Hughes and the implications this had on PHP builds.)

Daniel (17 May 2001)
- Colm Buckley posted a detailed bug report on (the debianized) 7.7.3, that
  turned out to be a problem with the debian-built 7.7.3-package that
  contained files from the 7.7.2 release!

- I added the CURLE_ALREADY_COMPLETE again, but with a fake value, just to
  make programs that use it, not fail when compiling against this version of
  libcurl.

Daniel (14 May 2001)
- Pawel A. Gajda fixed a problem with resumed transfers on re-used persistent
  connections.

Version 7.7.4-pre1

Daniel (14 May 2001)
- Jun-ichiro itojun Hagino fixed FTP PORT for IPv6-enabled libcurl.

- Added the first HTTPS test to the test suite in the release archive.

Daniel (12 May 2001)
- Jukka Pihl suggested that if (lib)curl is told to verify the peer's
  certificate and the peer can't be verified, it should fail and return a
  proper error code. I added a brand new error code named
  CURLE_SSL_PEER_CERTIFICATE for this purpose.

Daniel (11 May 2001)
- As was discussed with Frederic Lepied a while ago, I now made libcurl not
  return error even though no data was transfered on upload/download resume
  when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
  from the header file to make any implemenator that uses that to be aware of
  the fact that it can't be returned anymore!

- Improved general header-parsing to better allow white spaces and more.

- Rodney Simmons proved the fix I did yesterday was bad and I had to post
  another one.

- Ingo Wilken patched away two redirect problems more!
  
Daniel (10 May 2001)
- Cris Bailiff correctly noted that the space-after-header problem with
  Location: is present on several other places in the libcurl sources.

- Ingo Wilken patched away a problem libcurl had when following Location:
  headers with an extra space after the colon.

- Rodney Simmons found out that multiple FTP transfers did not treat relative
  directories correctly.

Daniel (9 May 2001)
- Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
  makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
  returned error. Starting now, it just don't output the file size instead.
  Anonymous bug report.

- stunnel.pm was accidentally left out from the release archive, it is now
  added (stunnel is needed to run the https-tests in the test suite)
  
Daniel (7 May 2001)
- Corrected two minor compiler warnings due to the FILE * to void * conversion
  that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
  filed a bug report on this.

Version 7.7.3

Daniel (4 May 2001)
- All callback functions now take 'void *' instead of 'FILE *'. This is made
  this way to make it more obvious to people that anything can be passed to
  them (by using the apropriate option). After discussions with Sterling
  Hughes.

Daniel (3 May 2001)
- Cris Bailiff fixed a chunked transfer encoding problem with persistent
  connection that made libcurl fail if the persistent connection used mixed
  chunked and non-chunked transfers.

- Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
  treated as content-length 0 replies but would cause a "hang" until the
  server timed-out and closed the connection.

- Brad Burdick found a minor problem in the docs/examples/Makefile.am

Daniel (27 April 2001)
- Updated the INTERALS document again. It was lagging a bit. I think I made it
  more easy to follow now as well.

- Brad Burdick found a problem with persistent connections when curl received
  a "Content-Length: 0" header.

- Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
  compiled/built on win32. It seems to work for unixes though!

- Dave Hamilton reported weird problems with CURL/PHP that I really can't
  explain at the moment. I'm hoping on some help from the PHP crew.

Daniel (26 April 2001)
- I rewrote the FTP command response function. I had to do it to make ftps
  work, as the OpenSSL read()-function didn't work the same way the normal
  unix read() does, but it was also a huge performance boost. Previously the
  function read one byte at a time, now it reads very large chunks, and it
  makes a notable speed difference.

Daniel (25 April 2001)
- Connection re-use when not using a proxy didn't work properly for
  non-default port numbers.

Daniel (24 April 2001)
- I've noticed that FTPS doesn't work. We attempt to use ssl even for the
