                               History of Changes

Version 6.5.1

Daniel (20 March 2000):
- An anynomous post on sourceforge correctly pointed out a possible buffer
  overflow in the curl_unescape() function for URL convertions. The main
  problem with this bug is that the ftp download uses that function and this
  single- byte overflow could lead to very odd bugs (as one reported by Janne
  Johansson).

Daniel (19 March 2000):
- Marco G. Salvagno <mgs@whiz.cjb.net> supplied me with a series of patches
  that now allows curl to get compiled on OS/2. It even includes a section in
  the INSTALL file. Very nice job!

Daniel (17 March 2000):
- Wham Bang <wham_bang@yahoo.com> (is that Pascal Gaudette?) supplied a patch
  for the lib/Makefile.vc6 file. We still need some fixes for the
  config-win32.h since it appears that VC++ and mingw32 have different
  opinions about (at least) unistd.h's existance.

Daniel (15 March 2000):
- I modified the -D/--dump-header workings so that it doesn't write anything
  to the file until it needs to. This way, you can actually use -b and -D
  on the same file if you want repeated invokes to store and read the cookies
  in that one single file.

- Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
  Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
  stuff from the sources (they're covered by the config-win32.h now).

- Pascal Gaudette <pascal@gaudette.org> fixed a missing ldap.c problem in the
  Makefile.vc6 file. He also addressed a problem in src/config-win32.h.

Daniel (14 March 2000):
- Paul Harrington pointed out that the 'http_code' variable in the -w output
  was never written. I fixed it now.

- Janne Johansson <jj@dynarc.se> reported the complaints that OpenBSD does
  when getdate.c #includes malloc.h. It claims stdlib.h should be included
  instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
  the configure.in for malloc.h and stdlib.h.

Version 6.5

Daniel (13 March 2000):
- <curl@spam.wolvesbane.net> pointed out that the way curl sent cookies in a
  single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
  the standards say, but I added a white space between the name/value pairs to
  perhaps make them work better.

- Added the perl check back in the configure.in again since the mkhelp.pl
  script needs it!

- Made some beautifications in the curl man page.

Daniel (3 March 2000):
- Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
  HAVE_STRDUP.

Daniel (3 March 2000):
- Uploaded the 6.5pre2 package.

Daniel (2 March 2000):
- Removed the perl-programs from the distribution, they never made many people
  happy and I'll still keep them available on the web.

- Added the -w and -N stuff to the man page. Documented the new progress meter
  display in README.curl.

- Jörn Hartroth <Joern.Hartroth@telekom.de>, Chris <cbayliss@csc.come> and Ulf
  Möller from the openssl development team helped bringing me the details for
  fixing an OpenSSL usage flaw. It became appearant when they released openssl
  0.9.5 since that barfed on curl's bad behaviour (not seeding a random number
  thing).

- Yet another option: -N/--no-buffer disables buffering in the output stream.
  Probably most useful for very slow transfers when you really want to get
  every byte curl receives within some prefered time. Andrew <tmr@gci.net>
  suggested this.

- Damien Adant <dams@usa.net> mailed me his fixes for making curl compile
  on Ultrix.

Daniel (24 February 2000):
- Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.

  I should also make a note here, if nothing else to myself, that when using
  the %-syntax for variables in DOS command prompts, you must use two %-
  letters for each one since that is an escape letter there! Maybe I should
  use another letter instead!

- Added more variables to -w:

  'http_code'
  'time_namelookup'
  'time_connect'
  'time_pretransfer'
  'url_effective'

- Made -w@filename read the syntax from a file and -w@- reads the syntax from
  stdin in the good old "standard" curl way.

Daniel (22 February 2000):
- Released a 6.5pre1 version to get some test and user feedback.

Daniel (21 February 2000):

- I added the -w/--write-out flag and some variables to go with it. -w is a
  single string, whatever you enter there will be written out when curl has
  completed a successful request. There are some variable substitutions and
  they are specifed as '%{variable}' (without the quotes). Variables that
  exist as of this moment are:

        total_time     - total transfer time in seconds (with 2 decimals)
        size_download  - total downloaded amount of bytes
        size_upload    - total uploaded amount of bytes
        speed_download - the average speed of the entire download
        speed_upload   - the average speed of the entire upload

  I will of course add more variables, but I need input on these and others.

- It struck me that the -# progress bar will be hard to just apply on the new
  progress bar concept. I need some feedback on this before that'll get re-
  introduced! :-/

Daniel (16 February 2000):
- Jörn Hartroth brought me some fixes for the progress meter and I continued
  working on it. It seems to work for http download, http post, ftp download
  and ftp upload. It should be a pretty good test it works generally good.

- Still need to add the -# progress bar into the new style progress interface.

- Gonna have a go at my new output option parameter next.

Daniel (15 February 2000):
- The progress meter stuff is slowly taking place. There's more left before it
  is working ok and everything is tested, but we're reaching there. Slowly!

Daniel (11 February 2000):
- Paul Marquis <pmarquis@iname.com> fixed the config file parsing of curl to
  deal with any-length lines, removing the previous limit of 4K.

- Eetu Ojanen <esojanen@jyu.fi>'s suggestion of supporting the @-style for -b
  is implemented. Now -b@<filename> works as well as the old style. -b@- also
  similarily reads the cookies from stdin.

- Reminder: -D should not write to the file until it needs to, in the same way
  -o does. That would enable curl to use -b and -D on the same file...

- Ellis Pritchard <ellis@citria.com> made getdate.y work for MacOS X.

- Paul Harrington <paul@pizza.org> helped me out finding the crash in the
  cookie parser. He also pointed out curl's habbit of sending empty cookies to
  the server.

Daniel (8 February 2000):
 - Ron Zapp <rzapper@yahoo.com> corrected a problem in src/urlglob.c that
   prevented curl from getting compiled on sunos 4. The problem had to do
   with the difference in sprintf() return code types.

 - Transfer() should now be able to download and upload simultaneously. Let's
   do some progress meter fixes later this week.

Daniel (31 January 2000):
 - Paul Harrington <paul@pizza.org> found another core dump in the cookie
   parser. Curl doesn't properly recognize the 'version' keyword and I think
   that is what caused this. I need to refresh some specs on cookies and see
   what else curl lacks to improve this a bit more once and for all.

   RFC 2109 clearly specifies how cookies should be dealt with when they are
   compliant with that spec. I don't think many servers are though...

 - Mark W. Eichin <eichin@thok.org> found that while curl is uploading a form
   to a web site, it doesn't read incoming data why it'll hang after a while
   since the socket "pipe" becomes full.

   It took me two hours to rewrite Download() and Upload() into the new
   single function Transfer(). It even seems to work! More testing is required
   of course... I should get the header-sending together in a kind of queue
   and let them get "uploaded" in Transfer() as well.

 - Zhibiao Wu <wuzb@erols.com> pointed out a curl bug in the location: area,
   although I did not get a reproducable way to do this why I have to wait
   with fixing anything.

 - Bob Schader <rschader@product-des.com> suggested I should implement resume
   support for the HTTP PUT operation, and as I think it is a valid suggestion
   I'll work on it.

Daniel (25 January 2000):
 - M Travis Obenhaus <Travis.Obenhaus@aud.alcatel.com> pointed out a manual
   mixup with -y and -Y that was corrected.
