CHANGES

Version 7.9.4-pre1

Daniel (30 January 2002)
- Georg Horn found another way the SSL reading failed due to the non-blocking
  state of the sockets! I fixed.

Daniel (29 January 2002)
- Multipart formposts now send the full request properly, including the CRLF.
  They were previously treated as part of the post data.

- The upload byte counter bugged.

- T. Bharath pointed out that we seed SSL on every connect, which is a time-
  consuming operation that should only be needed to do once. We patched
  libcurl to now only seed on the first connect when unseeded. The seeded
  status is global so it'll now only happen once during a program's life time.

  If the random_file or egdsocket is set, the seed will be re-made though.

- Giaslas Georgios introduced CURLINFO_CONTENT_TYPE that lets
  curl_easy_getinfo() read the content-type from the previous request.

Daniel (28 January 2002)
- Kjetil Jacobsen found a way to crash curl and after much debugging, it
  turned out it was a IPv4-linux only problem introduced in 7.9.3 related to
  name resolving.

- Andreas Damm posted a huge patch that made the curl_getdate() function fully
  reentrant!

- Steve Marx pointed out that you couldn't mix CURLOPT_CUSTOMREQUEST with
  CURLOPT_POSTFIELDS. You can now!

Daniel (25 January 2002)
- Krishnendu Majumdar pointed out that the header length counter was not reset
  between multiple requests on the same handle.

- Pedro Neves rightfully questioned why curl always append \r\n to the data
  that is sent in HTTP POST requests. Unfortunately, this broke the test suite
  as the test HTTP server is lame enough not to deal with this... :-O

- Following Location: headers when the connection didn't close didn't work as
  libcurl didn't properly stop reading. This problem was added in 7.9.3 due to
  the restructured internals. 'Frank' posted a bug report about this.

Daniel (24 January 2002)
- Kevin Roth very quickly spotted that we wrongly installed the example
  programs that were built in the multi directory, when 'make install' was
  used. :-/

Version 7.9.3

Daniel (23 January 2002)
- Andrés García found a persistancy problem when doing HTTP HEAD, that made
  curl "hang" until the connection was closed by the server. This problem has
  been introduced in 7.9.3 due to internal rewrites, this was not present in
  7.9.2.

Version 7.9.3-pre4

Daniel (19 January 2002)
- Antonio filed bug report #505514 and provided a fix! When doing multipart
  formposts, libcurl would include an error text in the actual post if a
  specified file wasn't found. This is not libcurl's job. Instead we add an
  empty part.

Daniel (18 January 2002)
- Played around with stricter compiler warnings for gcc (when ./configure
  --enable-debug is used) and changed some minor things to stop the warnings.

- Commented out the 'long long' and 'long double' checks in configure.in, as
  we don't currently use them anyway and the code in lib/mprintf.c that use
  them causes warnings.

- Saul Good and jonatan pointed out Mac OS X build problems with pre3 and how
  to correct them. Two compiler warnings were removed as well.

- Andrés García fixed two minor mingw32 building problems.

Version 7.9.3-pre3

Daniel (17 January 2002)
- docs/libcurl-the-guide is a new tutorial for our libcurl programming
  friends.

- Richard Archer brought back the ability to compile and build with OpenSSL
  versions before 0.9.5.
  [http://sourceforge.net/tracker/?func=detail&atid=100976&aid=504163&group_id=976]

- The DNS cache code didn't take the port number into account, which made it
  work rather bad on IPv6-enabled hosts (especially when doing passive
  FTP). Sterling fixed it.

Daniel (16 January 2002)
- Georg Horn could make a transfer time-out without error text. I found it and
  corrected it.

- SSL writes didn't work, they return an uninitialized value that caused
  havoc all over. Georg Horn experienced this.

- Kevin Roth patched the curl_version() function to use the proper OpenSSL
  function for version information. This way, curl will report the version of
  the SSL library actually running right now, not the one that had its headers
  installed when libcurl was built. Mainly intersting when running with shared
  OpenSSL libraries.  

Version 7.9.3-pre2

Daniel (16 January 2002)
- Mofied the main transfer loop and related stuff to deal with non-blocking
  sockets in the upload section. While doing this, I've now separated the
  connection oriented buffers to have one for downloads and one for uploads
  (as two can happen simultaneously). I also shrunk the buffers to 20K
  each. As we have a scratch buffer twice the size of the upload buffer, we
  arrived at 80K for buffers compared with the previous 150K.

- Added the --cc option to curl-config command as it enables so very cool
  one-liners. Have a go a this one, building the simple.c example:

        $ `curl-config --cc --cflags --libs` -o example simple.c

Daniel (14 January 2002)
- I made all socket reads (recv) handle EWOULDBLOCK. I hope nicely. Now we
  only need to address all writes (send) too and then I'm ready for another
  pre-release...

- Stoned Elipot patched the in_addr_t configure test to make it work better on
  more platforms.

Daniel (9 January 2002)
- Cris Bailiff found out that filling up curl's SSL session cache caused a
  crash!

- Posted the curl questionnaire on the web site. If you haven't posted your
  opinions there yet, go there and do it now while it is still there:

        http://curl.haxx.se/q/

- Georg Horn quickly found out that the SSL reading no longer worked as
  supposed since the switch to non-blocking sockets. I've made a quick patch
  (for reading only) but we should improve it even further.

Version 7.9.3-pre1

Daniel (7 January 2002)
- I made the 'bool' typedef use an "unsigned char". It makes it the same on
  all platforms, no matter what the platform thinks the default format for
  char is. This was noticed since we made a silly comparison involving such a
  bool variable, and only one compiler/platform combination (on Debian Linux)
  complained about it (that happened to have its char unsigned by default).

- Bug report #495290 identified a cookie parsing problem that was corrected.
  When a Set-Cookie: line is received without a trailing semicolon, libcurl
  didn't read the last "name=value" pair of the line, leading to confusions...

- Sterling committed his updated DNS cache code.

- I worked with Georg Horn and comments from Götz Babin-Ebell and switched
  curl's socket operations completely over to non-blocking for the entire
  operation (previously we used non-blocking only for the connection phase).
  We had to do this to make the SSL connection phase timeout properly without
  the use of signals. A little extra code to deal with this was added.

- T. Bharath pointed out a slightly obscure cookie engine flaw.

- Pete Su pointed out that libcurl didn't treat HTTP code 204 as it should.
  204-replies never provides a response-body. This resulted in bad persistant
  behavior when 204 was received.

Daniel (5 January 2002)
- SM updated the VC++ library Makefiles for the new source files.

Daniel (4 January 2002)
- I discovered that we wrongly used inet_ntoa() (instead of inet_ntoa_r() in
  two places in the source code). One happened with VERBOSE set on connects,
  and the other when VERBOSE was on and krb4 over nat was used... I honestly
  don't think anyone has suffered from these mistakes.

- I replaced a lot of silly occurances of printf() to instead use the more
  appropriate Curl_infof() or Curl_failf(). The krb4 and telnet code were
  affected.

- Philip Gladstone found a few more problems with 64-bit archs (the 64-bit
  sparc on solaris 8).

- After discussions on the libcurl list with Raoul Cridlig, I just made FTP
  response lines get passed to the header callback if such a one is
  registered. It'll make it possible for any application to get all the
  responses an FTP server sends to libcurl.

Daniel (3 January 2002)
- Sterling Hughes brought a few buckets of code. Now, libcurl will
  automatically cache DNS lookups and re-use the previous results first if any
  such is available. It greatly improves speed when doing many repeated
  operations to the same host.

- As the test case uses --include and then --head, I had to modify src/main.c
  to deal with this situation slightly better than previously. When done, we
  have 100% good tests again in the main branch.

Daniel (2 January 2002)
- Made test case 25 run again in the multi-dev branch. But it seems that the
  changes done on dec-20 made test case 104 cease to work (in both branches).

- Philip Gladstone pointed out a few portability problems in the source code
  that didn't compile on 64-bit sparcs using Sun's native
