                               History of Changes

Daniel (19 April 2001)
- Linus Nielsen Feltzing removed the decimals from the size variables in the
  --write-out output. We hardly ever get fraction of bytes! :-)

- Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.

Daniel (18 April 2001)
- Input from Michael Mealling made me add --feature to curl-config. It
  displays a list of features that have been built-in in the current
  libcurl. The currently available features that can be listed are: SSL, KRB4
  and IPv6.

- I committed Cris and Georg's perl interface work. They've got callbacks
  working and options that receives those slist pointers.

- Puneet Pawaia detected a problem with resumed downloads that use persistant
  connections and I made a rather large writeup to correct this. It is
  important that all session-data is stored in the connectdata struct and not
  in the main struct as this previously did.

Daniel (17 April 2001)
- Frederic Lepied fixed a ftp resumed download problem and introduced a new
  error code that lets applications be able to detect when a resumed download
  actually didn't download anything since the whole file is already present.
  Should this return OK instead?

- I added 'curl-config.in' to the root dir and configure script. Now, a
  curl-config script is made when curl is built. The script can be used to
  figure out compile time options used when libcurl was built, which in turn
  should be options YOU should use to build applications that use libcurl.

  This *-config style is not a new idea, but something that has been used
  successfully in other (library based) projects.

- Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
  for the If-Modified-Since style headers.

- Georg Schwarz pointed out an extra needed #include file needed in src/main.c
  for curl to build on Ultrix.

Daniel (11 April 2001)
- Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
  of the environment variable HTTP_PROXY in uppercase may become a security
  hazard when people use libcurl in a server/cgi situation where the server
  sets the HTTP_*-variables according to incoming headers in the HTTP
  request. Thus, a "Proxy:"-header would set that environment variable!

  Then, invoking curl_easy_perform() without having an URL set caused a crash.

- S. Moonesamy brought a patch that make curl use non-blocking connects on
  windows when connection timeout is set, as it allows windows users to set
  that timeout!

- Hirotaka Matsuyuki wrote a Ruby interface to libcurl!

- Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.

- I've written a first shot at a Java interface to libcurl. Many thanks to
  Daniel Marell for tirelessly answering to all my basic Java questions. It
  works, but it is still very basic.

Daniel (10 April 2001)
- The progress display could get silly when doing multiple file transfers, as
  it wasn't properly reset between transfers!

- Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
  me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
  function for writing headers. Previously you could only set a different FILE
  * when headers are written from within libcurl.

Daniel (7 April 2001)
- Andrés García fixed a problem in curl_escape() and pointed out a flaw in
  the curl_easy_setopt man page.

Daniel (6 April 2001)
- Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
  change their version define format often...

- curl_formfree() now accepts a NULL pointer without crashing!

Version 7.7.1

Daniel (3 April 2001)
- Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
  read bad memory during situations when an (ftp) connection attempt failed.
  Also, the lib/Makefile.vc6 was corrected.

- More investigations in the Location: following code made me realize that
  it was not clean enough to work transparantly with persistant and non-
  persistant connections. I think I've fixed it now.

Daniel (29 March 2001)
- Georg Horn mailed me some corrections for the Curl::easy perl interface.

- Experimental ftps:// support added. It is basically FTP over SSL for the
  control connection. It still makes all data transfers going over unencrypted
  connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
  that to verify the functionality.

Daniel (27 March 2001)
- Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
  to get a file from a site and it fails, the SIGALRM would still be sent
  after the timeout-time, quite inexpectedly!

- I added an ftp transfer example to docs/examples/ and I also wrote a tiny
  example makefile that can be used as a start when building one of the
  examples.

Version 7.7.1-beta1

Daniel (26 March 2001)
- Mohamed Lrhazi reported problems with 7.6.1 and persistant HTTP/1.0
  connections (when the server replied a Connection: Keep-Alive) and this
  problem was not properly dealt with in 7.7 either. A patch was posted to the
  curl-and-php mailing list.

Daniel (24 March 2001)
- Colin Watson reported about a problem and brought a patch that corrected it,
  which was about the man page and lines starting with a single quote (') in a
  way that gnroff doesn't like.

Daniel (23 March 2001)
- Peter Bray reported correctly that the root makefile used make instead of
  $(MAKE) for the test target.

- Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
  curl_setopt() which was removed in 7.7!

- S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).

- When following a Location:, libcurl would sometimes write to the URL string
  in a way it shouldn't. As the pointer is passed-in to libcurl from an
  application, we can't be allowed to write to it. The particular bug report
  from 'nk' that brought this up was because he had a read-only URL that then
  caused a libcurl crash!

- No longer reads HEAD responses longer than to the last header. Previously,
  curl would read the full reply if the connection was a "close" one.

- libcurl did re-use connections way too much. Doing "curl
  http://www.{microsoft,ibm}.com" would make it re-use the connection which
  made the second request return very odd results.

Daniel (22 March 2001)
- Edin Kadribasic made me aware that curl should not re-send POST requests
  when following 302-redirects. I made 302 work like 303 which means curl uses
  GET in the following request(s).

- libcurl now reset the "followed-location" counter on each invoke of
  curl_easy_perform() as it otherwise would sum up all redirects on the same
  connection and thus could reach the maxredirs counter wrongly.

- Jim Drash suggested curl_escape() should not re-encode what already looks
  like an encoded sequence and I think that's a fair suggestion.

Version 7.7

Daniel (22 March 2001)
- The configure script now fails with an error message if gethostbyname_r() is
  detected but it couldn't figure out how to invoke it (what amount of
  arguments it is supposed to get). Reports from Andrés García made me aware
  of this need.

- Talking with Jim Drash made me finally put the curl_escape and curl_unescape
  functions in the curl.h include file and write man pages for them. The
  escape function was modified to use the same interface as the unescape one
  had.

- No bug reports at all on the latest betas. Release time coming up.

Version 7.7-beta5

Daniel (19 March 2001)
- Georg Ottinger reported problems with using -C together with -L in the sense
  that the -C info got lost when it was redirected. I could not repeat this
  problem on the 7.7 branch why I leave this for the moment. Test case 39 was
  added to do exactly this, and it seems to do right.

- Christian Robottom Reis reported how his 7.7 beta didn't successfully do
  form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
  engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
  and POST operations that I need to add support for. Section 8.2.3 in RFC2616
  has all the details. Seems to work now!

Daniel (16 March 2001)
- After having experienced another machine break-down, we're back.

- Georg Horn's perl interface Curl::easy is now included in the curl release
  archive. The perl/ directory is now present. Please help me with docs,
  examples and updates you think fit.

- Made a new php/ directory in the release archive and moved the PHP examples
