                                  Changelog



Daniel (25 February 2004)
- Based on a patch by Greg Hewgill I modified how long long is used in the
  mprintf code, as we can use a 64bit type with MSVC that is a long long
  equivalent. This corrects some weird large file behaviors on windows.

- Tor Arntsen helped me work out --enable-debug to work better with different
  versions of the gcc and icc compilers.

- Added CURLOPT_SHARE to the curl_easy_setopt.3 man page.

Daniel (22 February 2004)
- Applied the final pieces of Gisle Vanem's patch that brings a working name
  resolve timeout to the windows versions of curl!

Daniel (21 February 2004)
- David Byron's fix to allow the speed-limit logic work even if you set
  limit-rate. It does work on the expense of the rate limiter.

Daniel (20 February 2004)
- configure --enable-debug with gcc now also tries to detect the icc compiler
  (which somehow gets treated as if it is a gcc) to stop using all the gcc
  options with it, and we also provide -isystem options for each extra -I
  option the configure script has figured out (for OpenSSL, kerberos, zlib,
  Heimdal etc). This of course to prevent warnings on headers we don't have
  control of.

Daniel (19 February 2004)
- Doug Porter made libcurl use the HOME environment variable before the
  getpwuid results when looking for .netrc files.

- If 'configure --enable-debug' is used with gcc, it now checks which gcc
  version it is and uses as picky compiler options as possible for the
  particular version.

- Code that can be used in both the lib and in the curl app is now made to use
  the curlx_ prefix. The first function to be available like this is the
  curlx_strtoll() function. This is made to allow the app to use existing code,
  but without polluting the libcurl API. Further explanations posted here:

    http://curl.haxx.se/mail/lib-2004-02/0215.html

Daniel (18 February 2004)
- Fixed buildconf to not use "which" as AIX and Tru64 have what have been
  referred to as "horribly broken 'which' programs".

- Made sure dns cache timeout set to -1 really means caching forever.

Daniel (17 February 2004)
- Made it possibly to build c-ares with the libcurl memdebug system to better
  track memory.

Daniel (16 February 2004)
- When using ares, we now initialize the ares 'channel' in curl_easy_init()
  and re-use that same handle during the entire curl handle's life-time. It
  improves performance.

- Fixed a problem when displaying verbose for ipv6-enabled libcurls and
  re-used connections. Problem reported and fix verified by Grigory Entin.

- Jeff Lawson fixed the version-check in the SOCKS5 code.

Daniel (15 February 2004)
- Fixed a case where a host cache entry was not flagged in-use properly when a
  cached entry was used.

- Andr<64>s Garc<72>a's patch that checks for winmm in the configure script was
  applied.

Daniel (13 February 2004)
- Ben Greear's SO_BINDTODEVICE patch for the binding of the local end to a
  specific network interface.

- Greg Hewgill found out that the variable holding 'contentlength' wasn't big
  enough to hold a large file!

- Tor Arntsen fixed a 64bit-related problem in date-related code in the ftp
  department, and there was another potential problem in the name resolve code
  too.

Daniel (11 February 2004)
- Removed a few variables that were only set but never used, as some compilers
  warn about that and we do not like compiler warnings!

- Removed the need for symlinks in the tests/data directory if curl is built
  outside of the source directory and the 'make test' is used. This was done
  by providing a "source dir path" to the scripts/servers.

- Now, if the configure script can't find an nroff tool or an option to nroff
  to use to convert man pages with, it will completely switch off the built-in
  manual.

- 'configure --disable-manual' completely disables the built-in manual from
  the curl command tool.

- Andr<64>s Garc<72>a fixed the configure script and a minor source edit, and now
  he has managed to get msys/mingw to run configure and then build!

Daniel (9 February 2004)
- The default HTTP Accept: header was modified to the much simpler
  "Accept: */*".

- P R Schaffner updated the curl-ssl spec file for RPMs.

- Dominick Meglio brought lots of documentation for the share interface's man
  pages that were previously missing.

- Tor Arntsen provided a patch that makes libcurl work-around a bug in the
  AIX5 implementation of getaddrinfo(). This makes the FTP PORT stuff work on
  ipv6-enabled AIX builds.

- Ken Rastatter provided portability fixes for the curlgtk.c example, and now
  it runs on windows with GTK as well!

Daniel (6 February 2004)
- Andr<64>s Garc<72>a made the configure script find gethostbyname() fine when run
  with mingw on windows.

- Modifed the ldap code to use proper function pointers all over (instead of
  mixed data and function pointers) to work-around the picky MIPSPro compiler
  warnings.

- A custom Host: header is only considered if the request is not made by
  following a location. After discussions with Tim Baker.

Daniel (5 February 2004)
- The libz part of the configure script now only set the two libz-related
  define HAVE_ZLIB_H and HAVE_LIBZ if both the lib and the header is found.
  If one is missing, none of the defines is set.

- Andr<64>s Garc<72>a fixed the Mingw makefiles.

- Len Krause reported that curl 7.9.X could do uploading from stdin without
  doing chunked encoding, which current curl cannot do even if you disable
  the transfer-encoding chunked header. Now it can again, and test case 98
  verifies this functionality.

- Tor Arntsen fixed a weird getaddrinfo() usage in the FTP code, preventing
  the ipv6-code for PORT work on AIX 5.2. We now also provide (better) error
  messages when bailing out in the that function.

- Tor Arntsen now provides AIX and IRIX (using gcc, xlc and the MIPSPro
  compilers) automated build logs (http://curl.haxx.se/auto/) and we've fixed
  numerous minor quirks to make less warnings appear.

Daniel (4 February 2004)
- Based on a patch by Gilad, we now use the custom timeouts when waiting for a
  server to connect when using FTP PORT. Previously we always waited 10
  seconds, no more no less. We now also changed the default (if no timeout is
  set) to wait 60 seconds for the connect before we fail.

Daniel (3 February 2004)
- Modified to link with c-ares instead of ares.

Daniel (2 February 2004)
- Added a configure test to check for which option the (g)nroff tool wants
  to extract plain text from the man pages. Tor Arntsen told us the AIX
  version of GNU gnroff doesn't support -man!

- Added an undef of accept in memdebug.h to make curl build with --enable-debug
  on AIX 5.2 which seems to have accept defined. Reported by Tor Arntsen.

- curl_version() now includes c-ares version info, and curl_version_info() now
  returns a struct with version SECOND that also includes that info.

- We are now officially using c-ares for asynch name resolves. c-ares is the
  new library, based on the existing ares but with an extended and slightly
  modified API.

- Dirk improved the ares timeout code, and now we also include the ares error
  string when we fail to resolve a name.

- Another tweak to make test case 91 run fine. Now we have another bit on a
  connection that is set true if the connection is marked for 'retry'. That
  makes the connection get closed and re-opened and the HTTP-done code must
  not complain on the fact that no data was received.

- Based on Dirk Manske's patch, I modified the name resolving with ares to
  feature a timeout for really slow lookups. It now defaults to 300 seconds,
  but is now adjusted to the CONNECTTIMEOUT/TIMOUE timeouts if one of them
  is set.

- Fixed the inclusion of ca-bundle.h to really use the one in the build dir
  before the one in the source dir. Domenico Andreoli found out and reported.

- Added test case 97, a simple POST with a custom Content-Type header
  replacing the original application/x-www-form-urlencoded one.

Daniel (30 January 2004)
- Added code that attempts to fix the test 91 failure. As has been figured out
  by Patrick Smith, the error happens because we re-use a connection that the
  server is just about to close and we even manage to send away the request
  without seeing an error. On the first read attempt we get a ECONNRESET.
  Starting now, we attempt to detect this and if so, we retry the request on a
  fresh connection.

- I added test case 510 which is a custom program that does a POST using a
  read callback, with chunked transfer-encoding.

- Adjusted one of the MPE/iX changes as it made test case 504 fail all over.

- Added --socks as a recognized option. It works just like --proxy but sets a
  SOCKS5 proxy to use. SOCKS5 support has been available in libcurl for a
  while, just not provided by the curl tool. This does not currently work for
  IPv6-enabled libcurls.

Daniel (29 January 2004)
- Stadler Stephan pointed out that src/hugehelp.c included config.h without
  checking the define if its present...

- Ken Hirsch provided patches to make curl build fine on the MPE/iX operating
  system.

- Dan Fandrich compiled curl with lots of aggresively pedantic compiler
  options and thus found a few minor errors and did some general cleanups to
  avoid them.

- Dirk Manske fixed a flaw in ares that prevented it to use non-blocking
  sockets properly.

Daniel (28 January 2004)
- Richard Bramante fixed chunked transfer-encoded "uploads" to send a final
  CRLF combo properly.

Daniel (27 January 2004)
- Made the response-headers during a CONNECT request to a proxy get passed on
  as regular headers, so they appear with -i/-I options and similar.

- Based on a patch by Gisle Vanem, I've made the progress meter display
  properly switch to a GB-display when more than 9999MB have been transfered.

Daniel (23 January 2004)
- Gisle Vanem pointed out a curlrc parser problem/crash when an option with a
  required didn't have one and was on the last line of a file.

- More Windows fixes for large files. We now build and link with
  ../lib/strtoofft.c in the app code since Curl_strtoll() is not a provided
  libcurl function... Perhaps we should consider a 'common' dir or similar
  where we put source code used in both the lib and the client. Or perhaps
  we'll just make this function available in the library...

- Vincent Bronner found out the socks5 code crashed when no username was
  set.

- Vincent Bronner spotted a problem with proxy username/password when re-using
  a persistant connection.

- Fixed the progress meter display for files larger than 2^31 bytes. Gisle
  Vanem reported.

Daniel (22 January 2004)
- Gisle Vanem made strtoll() get used when curl is built with the mingw
  compiler.

- Gisle Vanem fixed the compressed help text code to display properly.

- Removed the '#define HttpPost' from the public header file, as curl_httppost
  is the proper name and it has been for quite some time now. Fixes another
  name space pollution.

- Added 'curl_off_t' typedef in the public header file, to be used to provide
  large file sizes to the *_LARGE options. Adjusted the code all over to use
  this variable type instead of 'off_t'. This is an attempt to make the large
  file support work on more platforms. The configure script now checks the
  size of the curl_off_t instead of the plain off_t.

Version 7.11.0 (22 Januari 2004)

Daniel (21 January 2004)
- Removed the defines in the public header file with TIMECOND_ prefixes. They
  have been obsolete since April 22nd 2002, and if this causes anyone any
  problems now it is very easy to just add CURL_ to the names. This corrects
  this name space pollution.

Daniel (19 January 2004)
- David Byron cleaned up how --trace with no option was treated, and also
  arguments in a config file without a required parameter!

Daniel (16 January 2004)
- Gisle Vanem fixed a few issues where compilers warned about variables
  possibly being used unassigned.

- Minor Interix build problem fixed.

Daniel (15 January 2004)
- Peter Sylvester pointed out some necessary escaping needed in the
  acinclude.m4 file when automake 1.8 or later is used.

Daniel (14 January 2004)
- Vincent Bronner fixed the Curl_resolv() return code. This extends the fix
  Steve Green provided on december 3...

Daniel (13 January 2004)
- Luke Call made the win32 version of the password prompting function support
  backspace.

- Dan Fandrich fixed the hugehelp source file to contain both a compressed and
  an uncompressed version in the distribution, so that more people easier can
  build curl with the compressed version.

- Diego Casorran brought another AmigaOS build patch for native Amiga builds.

- Matt Veenstra updated the Mac OS X framework files.

- Brian R Duffy brought a section to the INSTALL file on how to build a
  SSL-enabled curl using the free Borland C++ compiler. He also updated the
  Borland lib/Makefile.b32.

- I fixed the test case 509 which I broke yesterday. Now the libtest are
  compiled with an include path that points to the library's source dir, so
  that the libtests can include files from the source tree. This was made to
  make it possible to use the USE_SSLEAY define in the library test files.

Daniel (12 January 2004)
- Peter Sylvester brought code that now allows a callback to modified the URL
  even when the multi interface is used, and then libcurl will simulate a
  "follow location" to that new URL. Test 509 was added to test this feature.

- Extended the time we retry servers in the test script, and I also made it
  retry the https and ftps servers before they are considered bad. I believe
  the previous approach could turn problematic on really slow hosts.

Version 7.11.0-pre1 (12 January 2004)

Daniel (11 January 2004)
- Dominick Meglio pointed out FTPS should use default port 990 according to
  IANA.

Daniel (8 January 2004)
- Fixed the SPNEGO configure check to not use -R or other non-portable options
  in the LDFLAGS. Reported by Pierre in bug report #872930.

Daniel (5 January 2004)
- Dan Fandrich provided a fix on our zlib usage.

- David J Meyer's patch that introduce large file support to libcurl was
  applied. New curl_easy_setopt options that accept 'off_t' arguments are:

  INFILESIZE_LARGE
  RESUME_FROM_LARGE
  MAXFILESIZE_LARGE

Daniel (4 January 2004)
- Based on Dominick Meglio's comments, I made our private version of
  gettimeofday() declared static. This would otherwise collide with the same
  function in other libs (like ares for example).

- Added Dominick Meglio's description on how to build libcurl with ares
  on win32.

Daniel (19 December)
- CURLOPT_IPRESOLVE was not possible to set.

- Gisle Vanem updated the djgpp build files.

Daniel (18 December)
- John McGowan reported a redirect-problem that happened if a site used a URL
  like "url.com?var=content" (without a proper slash) and from that address
  redirected the user-agent to an absolute directory.

- David Byron made libcurl build fine with both the .NET and VC6 versions of
  MSVC

Daniel (16 December)
- Updated test 506 since it started to fail after the cache prune change
  yesterday. I also changed it slightly to feature a counter in each debug
  output for easier tracing.

Daniel (15 December)
- Old DNS cache entries are now only pruned after curl is done with a request,
  and not in the actual name resolve call.

- corrected the --enable-ares patch

- Giuseppe Attardi found and fixed a problem within libcurl that re-used
  already freed memory.

Daniel (10 December)
- Gisle Vanem reported that the dict support was broken. I broke it during my
  ftps-changes overhaul. I've now added a 'curlassert' function that can be
  used to verify expressions, to prevent future errors of the same
  kind. They're only present in debug-builds.

- Diego Casorran made curl and libcurl possible to build natively (no more
  need for the ixemul library) on AmigaOS.

- Dominick Meglio made configure --enable-ares support a given path to the
  installed ares lib, instead of always using it in the curl source tree.
  This also fixed the curl-config --libs output.

- Eric S. Raymond patched a very minor man page format error in
  libcurl-errors.3

Daniel (8 December)
- Fixed the flaw that made -lz appear twice on the link command line.

- After correspondance with Gisle Vanem, I changed the 'connection aborted'
  error text when the FTP response reader failed to more specificly identify
  what the problem is.

- Based on a patch from Dominick Meglio, curl-config --feature now outputs
  'AsynchDNS' as a feature if libcurl was built with ares. The feature name
  is the same that 'curl -V' outputs, for simplicity.

Daniel (3 December)
- Marty Kuhrt made the build up-to-date on VMS, and moved most of the VMS-
  specific stuff in the client code to a separate header file.

- Steve Green fixed a return code bug in Curl_resolv(), that made the socks5
  code fail.

- swalkaus at yahoo.com patched libcurl to ignore Content-Length: headers
  when Tranfer-Encoding: chunked is used, as mandated by RFC2616.

Daniel (2 December)
- --ftp-pasv was added, which serves the only purpose of overriding a
  previously set --ftpport option. Starting now, --ftp-port is a recognized
  alias for --ftpport for consistency.

- Giuseppe Attardi pointed out that we should use MSG_NOSIGNAL when we use
  send() and recv(). I added checks for the define in the configure script and
  adjusted the code accordingly. If the symbol is present, we won't attempt
  to ignore the SIGPIPE signal.

Daniel (1 December)
- Mathias Axelsson set up a bsdftpd-ssl server for me and I could make curl
  run fine against its FTPS implementation. Now these FTPS-related things
  work:
   o explicit and implicit FTPS
   o active (PORT) and passive (PASV)
   o upload and download
   o verified against bsdftpd-ssl and RaidenFTPD

Daniel (27 November)
- James Clancy made the Borland Makefiles up to date.

- Markus Moeller improved the SPNEGO detection in the configure script.

Daniel (25 November)
- Dave May filed bug report #848371, identifying that if you'd do POST over a
  proxy to a https server, libcurl didn't POST at all, it just made a GET! It
  turned out to be because libcurl wrongly didn't consider the authentication
  "negotiation phase" to be complete yet.

  I added test case 95 to verify my fix for this.

Daniel (24 November)
- Thanks to Mathias Axelsson, I've been able to work on FTPS for libcurl and it
  seems to work somewhat fine now.

  The FTPS stuff is based on RFC2228 and the murray-auth-ftp-ssl draft
  (version 12). There seems to exist quite a few servers that have implemented
  the server side of this.

  We can now use ftps:// URLs to explicitly switch on SSL/TSL for the control
  connection and the data connection (dealing with two SSL connections forced
  me to change a lot of stuff in libcurl).

  Alternatively, and what seems to be the recommended way, we can set the new
  option CURLOPT_FTP_SSL to one of these values:

     CURLFTPSSL_NOPE,   - do not attempt to use SSL
     CURLFTPSSL_TRY     - try using SSL, proceed anyway otherwise
     CURLFTPSSL_CONTROL - SSL for the control connection or fail
     CURLFTPSSL_ALL     - SSL for all communication or fail

  Any failure to set the desired level will make libcurl fail with the error
  code CURLE_FTP_SSL_FAILED. This new option makes a "normal" ftp:// transfer
  attempt to be made securely.

  I've been able to login and get files (passively) from Mathias' server using
  both ftps:// and CURLOPT_FTP_SSL. (I've made 'curl' understand the --ftp-ssl
  option that sets CURLFTPSSL_TRY.)

- Gaz Iqbal fixed a range string memory leak.

- Gisle Vanem fixed the Windows builds.

- Added the new FTPSSL defines in curl/curl.h

Daniel (20 November)
- Josh Kapell filed bug report #845247 as he found an endless loop when
  getting a 407 back from a proxy when no user+password was given. Added test
  case 94 to verify the fix.

Daniel (19 November)
- Kevin Roth fixed a progress-bar problem on Windows.

- While working with Nicolas Croiset's bug report #843739, I noticed two minor
  problems related to ftp partial downloads: if a partial transfer is
  detected, we must close the connection as we cannot know in what state it is
  anymore. This looks like a ProFTPD bug:
  http://curl.haxx.se/mail/lib-2003-11/0079.html

Daniel (17 November)
- Maciej W. Rozycki made the configure script use a cache variable for the
  writable argv test. This way, the default can be overridden better (for
  cross-compiles etc)

Daniel (15 November)
- Mathias Axelsson found out libcurl sometimes freed the server certificate
  twice, leading to crashes!

Daniel (14 November)
- Siddhartha Prakash Jain found a case with a bad resolve that we didn't
  properly bail out from, when using ares.

Daniel (13 November)
- Default Content-Type for parts in multipart formposts has changed to
  "application/octet-stream".  This seems more appropriate, and I believe
  mozilla and the likes do this. In the same area: .html files now get
  text/html as Content-Type. (Pointed out in bug report #839806)

- Gisle Vanem corrected the --progress-bar output by doing a flush of the
  output, which apparently makes it look better on at least windows, but
  possibly other platforms too.

- Peter Sylvester identified a problem in the connect code, which made the
  multi interface on a ipv6-enabled solaris box do bad. Test case 504 to be
  specific. I've spent some time to clean-up the Curl_connecthost() function
  now to use less duplicated code for the two different sections: ipv6 and
  ipv4.

Daniel (11 November)
- Added CURLOPT_NETRC_FILE. Use this to tell libcurl which file to use instead
  of trying to find a .netrc in the current user's home directory. The
  existing .netrc file finder is somewhat naive and is far from perfect on
  several platforms that aren't unix-style. If this option isn't set when
  CURLOPT_NETRC is set, the previous approach will still be used.

  The current .netrc check code now also support longer than 256 bytes path
  names.

Daniel (10 November)
- Kang-Jin Lee pointed out that the generated ca-bundle.h file shouldn't be
  written in the source dir if a different build dir is used.

- After S<>bastien Willemijns' bug report, we now check the separators properly
  in the 229-reply servers respond on a EPSV command and bail out better if
  the reply string is not RFC2428-compliant.

Daniel (7 November)
- Based on Gisle Vanem's patch, I made curl try harder to get the home
  directory of the current user, in order to find the default .curlrc file.
  We're also considering moving out the HOME-dir code from libcurl, and
  instead have the app pass in the path to the .netrc file (which is the only
  logic left in libcurl that uses the HOME dir). Then curl can use the home
  dir for that purpose too.

- Ralph Mitchell's updated testcurl.sh to the script to take an existing
  directory name and build/run/test curl in there instead of trying to update
  from CVS. Using this approach, the script can now be used to test daily
  tarballs etc.

- Gisle Vanem added a "resource file" to the Windows DLL builds, to contain
  information such as version number, library name, copyright info etc.

Daniel (6 November)
- curl checks if the existing libcurl supports things like --ntlm, --negotiate
  and --krb4 and returns error if not.

- I added three new global defines in the curl/curl.h header:
  LIBCURL_VERSION_MAJOR, LIBCURL_VERSION_MINOR and LIBCURL_VERSION_PATCH. They
  are the three numbers in the library's version number, separated for easier
  usage. 'maketgz' was updated accordingly to generate these numbers properly
  when building release-archives.

- Uninitialized variable fix, reported by both Marty Kuhrt and Benjamin
  Gerard.

- Matt Veenstra provided build files to build libcurl as a "framework" under
  Mac OS X. See the lib/libcurl.framework.make for details.

- Removed the defines of TRUE and FALSE from the curl/curl.h header file.
  They're not in our name space so we should not fiddle with them.

Daniel (5 November)
- Replaced the man page to HTML converter program with a new one: roffit.
  Makes nicer web pages.

Daniel (4 November)
- Troels Walsted Hansen fixed the MSVC makefiles to let them build curl fine
  on Windows.

- Kevin Roth corrected the cygwin package generator and spell-fixed the
  comment in the ca-bundle.h file.

Version 7.10.8 (1 November 2003)

Daniel (31 October)
- Assume that MDTM on an FTP server returns the timestamp using the UTC time
  zone. This changes the time CURLINFO_FILETIME returns for a given file over
  FTP, and will change existing uses of CURLOPT_TIMECONDITION. It will make
  the functionality more similar to how the HTTP one is already working.

- Command line options that take numerical parameters (such as -y, -Y, -C etc)
  now report error and exit if the parameter isn't truly a number greater than
  or equal to zero. This helps users to notice bad usage earlier. Before, when
  a user forgot or missed to add a numerical parameter to an option, the
  command line parser would simply "eat" the following option and it would
  cause great confusion.

Daniel (30 October)
- David Hull made libcurl deal with NOBODY and HEADER for file:// the same way
  it already does for FTP: it provides HTTP-looking headers that provide info
  only about the file, without doing the actual transfer. The curl tool then
  lets --head do this.

Daniel (29 October)
- runtests.pl now checks for and use valgrind if present. It will redirect the
  valgrind results in log/valgrind[num] but it currently doesn't scan that
  file for any errors or anything, that is still only made manually.

- David Hull made the file: URL parser also accept the somewhat sloppy file
  syntax: file:/path. I added test case 203 to verify this.

Daniel (28 October)
- Dan C tracked down yet another weird behavior in the glibc gethostbyname_r()
  function for some specific versions (reported on 2.2.5 and 2.1.1), and
  provided a fix. On Linux machines with these glibc versioins, non-ipv6
  builds of libcurl would often fail to resolve perfectly resolvable host
  names.

Daniel (26 October)
- James Bursa found out that curl_msnprintf() could write the trailing
  zero-byte outside its given buffer size. This could happen if you generated
  a very long error message as then libcurl would overwrite the ERRORBUFFER
  with one byte. Using a non-existing very long local file:// name is one case
  that could make this occur.

Daniel (24 October)
- David Hull filed bug report #829827. It identified a problem with -C - if
  the full file already was downloaded and thus the server responded with a
  416. libcurl would then wrongly use the Content-Length: header and expect
  that size to get transfer, causing a "hang" until the server closed the
  connection and then an error 18 ("still N bytes data left of the transfer").

  Now we don't return any error at all, but I think libcurl should perhaps
  return some kind of info since the requested range was out of the size of
  the document.

- Based on David Hull's fix in bug report #804599, we now check for solaris and
  gcc in configure and set the -mimpure-text link flag for linking the lib
  better.

- I've introduced a -t option to the runtests.pl script. With that option set,
  the script runs special "memory torture" tests. For each test command line
  in that section, the script first runs the command line and counts the total
  amount of allocations made. It then runs the exact same command line again,
  forcing allocation number N to fail. It will try every N from 1 to the total
  number of amounts made. For every invoke, it checks that no memory was
  leaked as that would indicate a bad cleanup somewhere in the code.

  This is just beginning to work, and I've already made some corrections in
  libcurl code. When this code works somewhat fine, I'll make sure 'make test'
  in the root dir will run these tests as well.

Daniel (23 October)
- Georg Horn fixed how the CA verification is made. Verifications can now be
  made while at the same time the result of it can be ignored. This also
  affects the curl tool as -k can now be used together with --cacert or
  --capath.

Daniel (22 October)
- Gisle Vanem found out --disable-eprt didn't work and patched it.

- Test case 91 was modified and could now repeat the problem Kevin Roth has
  reported, and the bug was fixed.

- Dylan Ellicott added vc-libcurl-ssl-dll as a target to the root makefile
  to build a static libcurl that links with a shared OpenSSL using MSVC.

Daniel (21 October)
- Andr<64>s Garc<72>a updated the mingw32 makefiles.

Version 7.10.8-pre5 (21 October 2003)

Daniel (19 October)
- Georg Horn made libcurl output more info on SSL failures when receiving
  data.

Version 7.10.8-pre4 (18 October 2003)

Daniel (17 October)
- Dominick Meglio implemented CURLOPT_MAXFILESIZE and --max-filesize.

- Made libcurl show verbose info about what auth type and user name that is
  being sent in its HTTP request-headers.

Daniel (16 October)
- Removed support for CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA. libcurl
  no longer prompt for passwords under any circumstances. Password prompting
  was instead moved to curl, which now prompts for password if -u or -U lack
  it. This solves the problem Kevin Roth reported when curl prompted for
  password twice when doing NTLM authentication.

- I rewrote the SSL subjectAltName check to avoid having to rely on OpenLDAP-
  licensed derivate code.

Daniel (15 October)
- Avoid doing getsockopt() on Windows to verify connects. It seems that this
  hogs Windows machines when libcurl is being used multi-threaded (with > ~50
  threads). Andrew Fuller helped us verify and test this.

Daniel (14 October)
- Kimmo Kinnunen fixed a crash with duphandle() when CURLDEBUG is set.

- Gisle Vanem made libcurl build and work with IPv6 on Windows.

Daniel (13 October)
- Giuseppe Attardi reported yet another segfault with ares and the multi
  interface. Me fixed.

- Domenico Andreoli removed the extra LDFLAGS assignment in lib/Makefile.am
  that was reported about in the debian bug report #212086.

  Domenico also fixed two makefiles where we used 'gnroff' instead of the more
  portable $(NROFF).

Daniel (12 October)
- Dirk Manske made the share locking around DNS lookups slightly different to
  allow the share system's DNS lookups to run somewhat more
  independent/faster.

Daniel (9 October)
- Lachlan O'Dea fixed a resume problem: "If I set CURLOPT_RESUME_FROM, perform
  an HTTP download, then reset CURLOPT_RESUME_FROM to 0, the next download
  still has a Range header with a garbage value." bug report #820502

- Dominick Meglio made the inet_pton.c file build fine using MSVC.

- The 'sws' test suite web server now #include setup.h from the lib directory.
  This makes it more portable easier.

Version 7.10.8-pre3 (8 October 2003)

Daniel (8 October)
- Frank Ticheler provided a patch that fixes how libcurl connects to multiple
  addresses, if one of them fails (ipv4-code).

Daniel (7 October)
- Neil Dunbar provided a patch that now makes libcurl check SSL
  subjectAltNames when matching certs. This is apparently detailed in RFC2818
  as the right thing to do. I had to add configure checks for inet_pton() and
  our own (strictly speaking, code from BIND written by Paul Vixie) provided
  code for the function for platforms that miss it.

- HTTP POST using the read callback didn't work, as Florian Schoppmann
  reported.

Daniel (5 October)
- Shared provided a few fixes to make libcurl build on BeOS
  out-of-the-box. New code for BeOS-style non-blocking sockets, provided by
  Shard and Jeremy Friesner. Modified the autoconf check for non-blocking
  sockets to check for this kind too.

Daniel (4 October)
- Vincent Bronner pointed out that if you set CURLOPT_COOKIE for a transfer
  and then set it to NULL in a subsequent one, the previous cookie was still
  sent off!

- Jon Turner fixed a problem libcurl had when it failed on an FTP transfer due
  to a bad path, it would cause the next transfer to use a bad path as well.

- Siddhartha Prakash Jain provided a patch with a fix for libcurl with ares,
  when working on IP-only names as we then could return "wait" status when the
  name in fact already was resolved. I edited the patch slightly to not expose
  async details to non-ares aware source code.

Daniel (3 October)
- Neil Spring posted the debian bug report #213180, and pointed out that using
  the name 'access' in a function prototype is not very wise as some compilers
  complain.

- Peter Sylvester provided his and Jean-Paul Merlin's curlx.c example source
  code that shows how they use ssl and callbacks.

Daniel (2 October)
- James MacMillan's patch makes curl build on QNX 6.2.x.

Daniel (26 September)
- My daughter was born!

Daniel (23 September)
- Added support for -4/--ipv4 and -6/--ipv6 to force names to resolve to that
  particular IP version. They only work for IPv6-enabled libcurls.

- curl -V now outputs 'SPNEGO' as a feature in case libcurl was built to
  support that.

Version 7.10.8-pre2 (22 September 2003)

Daniel (22 September)
- Giuseppe Attardi found a segfault in libcurl when using the multi interface
  with ares and doing repeated operations against a non-resolving host name.

Daniel (19 September)
- Added the CURLOPT_IPRESOLVE option, that allows an application to select
  what kind of IP addresses he wants to use when resolving host names. This
  is only interesting when using host names that resolve addresses using more
  than one version of IP.

- Applied Markus Moeller's patch that introduces SPNEGO support if libcurl
  is built with the FBopenssl libraries. curl_version_info() now returns
  info on SPNEGO availability. The patch also made the GSSAPI stuff work fine
  with the MIT GSS-library (the Heimdal one still works too).

Daniel (16 September)
- Doing PUT with --digest failed, as reported in bug report #805853.

- Using --anyauth that picked NTLM, and then a redirect closed the connection
  and took curl to a second NTLM page made curl fail. Bug report #806328
  identified the problem, test case 90 was added to verify the fix.

Daniel (14 September)
- codemastr brought a patch for ares to make the Windows portions of it work
  properly on NT4. I uploaded a new diff and updated the docs on where to get
  it etc.

- Jeff Pohlmeyer tracked down a very hard-to-find bug where we removed a
  cached DNS entry even though it may be in use, which caused "random" memory
  to get overwritten and thus "random" crashes.

Daniel (12 September)
- Based on a bug report by David Kimdon, I made the runtests.pl script clear
  all possible proxy environment variables before the tests are run.

- By default, easy handles within a multi handle now share DNS cache.

- Tim Bartley brought a patch that makes the GSSNEGOTIATE option work for
  Microsoft's "Negotiate" authentication as well.

Daniel (11 September)
- A zero-length proxy string confused FTP transfers.

- Bjorn Reese found a case with an uninitialized pointer, only present when
  built for ares.

Version 7.10.8-pre1 (8 September 2003)

Daniel (7 September)
- Jurij Smakov found out that the non-OpenSSL MD5 code was not working on
  Alpha (or ia64). Only the OpenSSL-version did. I made a fix I think corrects
  the problem. 

Daniel (5 September)
- Kevin Fisk reported that configure --enable-thread didn't work. I fixed.

- De-macrofied the lib/hash.c source code somewhat.

Daniel (4 September)
- CURLINFO_HTTPAUTH_AVAIL and CURLINFO_PROXYAUTH_AVAIL added, Based on Joerg
  Mueller-Tolk's patch,

Early (4 September)
- Added CURLOPT_FTP_RESPONSE_TIMEOUT - allows user to set strict timeout
  requirements on the FTP server's ability to respond to individual commands
  without placing global requirements on transfer or connect time.  Files
  affected:
    - include/curl/curl.h
        Added option CURLOPT_FTP_RESPONSE_TIMEOUT
    - lib/ftp.c
        Added branch inside Curl_GetFTPResponse to check for 
        data->set.ftp_response_timeout
    - lib/url.c
        Modified Curl_setopt to recognize CURLOPT_FTP_RESPONSE_TIMEOUT
    - lib/urldata.h
        Added ftp_response_timeout to struct UserDefined

Daniel (3 September)
- Peter Pentchev found and fixed two problems in the test suite's web server
  code, that made it segfault at times.

- J<>rg Mueller-Tolk improved the proxy user+password handling, especially
  when providing a blank password.

Daniel (2 September)
- Fix for making CONNECT to proxies do the correct magic to allow NTLM, Digest
  and similar to work.

Daniel (1 September)
- Henrik Storner made libcurl work fine with OpenLDAP 2.1.22 (current).

- Jeff Pohlmeyer added a proper error message for non-resolving hosts when
  using ares for lookups.

Daniel (25 August)
- John McGowan reported that curl -k still failed if the HTTPS server's CN
  field wasn't obtainable. This was due to the CURLOPT_SSL_VERIFYHOST being
  set to 1, and libcurl failed if the CN was missing. Starting now, having it
  set to 1 will simply output a warning if no CN could be obtained (as having
  a mismatch is OK).

Daniel (21 August)
- Vincent Sanders provided a fix for name resolving when linked with uClibc.

Daniel (20 August)
- Gerd v. Egidy provided a patch that makes libcurl store the FTP response
  code from ftp servers. Using curl_easy_getinfo() with CURLINFO_HTTP_CODE
  returns that data. The option is therefore now also known as
  CURLINFO_RESPONSE_CODE.

- Antoine Calando found a segfault when doing multi-part/formpost using
  the multi interface.

- Antoine Calando pointed out that curl_multi_info_read() didn't set the
  msgs_in_queue to 0 properly when returning NULL.

Daniel (19 August)
- I made curl support multiple -T options, as well as -T "{file1,file2}"
  style globbing. One -T for each URL is supported.

- Jeff Pohlmeyer found a segfault when using ares-enabled libcurl and the
  multi interface when trying a non-existing host name.

- Made the libcurl printf code support long longs if available.

- Loren Kirkby pointed out that we did not clean up all SSL-allocated memory
  in curl_global_cleanup().

Daniel (17 August)
- Setting CURLOPT_WRITEFUNCTION or CURLOPT_READFUNCTION to NULL will now make
  them get the internal defaults restored. Previously this could cause a
  segfault. We should aim at having all pointer-related options get restored
  to default/safe values when set to NULL.

Version 7.10.7 (15 August 2003)

Daniel (14 August)
- I modified the memdebug system to return failure on memory allocation
  functions after a set amount of successful ones. This enables us to test
  out-of-memory situations in a controlled manner and we can make sure that
  curl/libcurl behaves good in those.

  This made me find and fix several spots where we did not cleanup properly
  when bailing out due to errors (low memory).

- Corrected test case 74. Made using -o with bad #[num] codes complain and
  bail out. Made #[num] support numbers larger than 9 as well. Added test
  case 86 for a proper range globbing test as well.

Version 7.10.7-pre4 (12 August 2003)

Daniel (12 August)
- curl_version_info() now returns a flag if libcurl was built with asynch DNS
  support, and this is now also displayed with 'curl -V'.

- Added a few new man pages to the docs/libcurl dir: curl_share_init,
  curl_share_setopt, curl_share_cleanup, libcurl-easy and libcurl-share.

Daniel (11 August)
- Mike Cherepov made the local binding code work for Windows, which makes
  the option CURLOPT_INTERFACE work on Windows as well.

- Vincent Sanders updated the fopen.c example code a lot.

- --proxy-ntlm is now supported by the curl tool. It forces the proxy
  authentication to be made using NTLM. It does not yet work for HTTPS over
  proxies (or other proxy-tunneling options). Test case 81 and 82 do some
  simple initial ntlm testing.

- Found and fixed a minor memory leak on re-used connections with
  proxy-authentication.

- I removed -@ and -Z as valid short options. They were very rarely used (@
  wasn't even documented).

- Serge Semashko introduced CURLOPT_PROXYAUTH, and make it work when set to
  CURLAUTH_NTLM and/or CURLAUTH_BASIC. The PROXAUTH is similar to HTTPAUTH,
  but is for the proxy connection only, and HTTPAUTH is for the remote host.

- Fixed loading of cookies with blank contents from a cookie jar. Also made the
  cookie functions inform on added and skipped cookies (for cookie debugging).

Version 7.10.7-pre3 (8 August 2003)

Daniel (8 August)
- Applied David Byron's fix for file:// URLs with drive letters included.

- I added the --ftp-create-dirs to the client code, which activates Early's
  CURLOPT_FTP_CREATE_MISSING_DIRS option, and wrote test case 147 to verify
  it. Added the option to the curl.1 man page too. Added the option to the
  curl_easy_setopt.3 man page too.

Daniel (7 August)
- Test case 60 failed on ia64 and AMD Opteron. Fixed now.

- Fixed a printf problem that resulted in urlglobbing bugs (bug #203827 in the
  debian bug tracker). Added test case 74 to verify the fix and to discover if
  this breaks in the future.

- "make distcheck" works again.

Version 7.10.7-pre2 (6 August 2003)

Daniel (5 August)
- Duncan Wilcox helped me verify that the latest incarnation of my ares patch
  builds fine on Mac OS X (see the new lib/README.ares) file for all details.

- Salvatore Sorrentino filed bug report #783116 and Early Ehlinger posted a
  bug report to the libcurl list, both identifying a problem with FTP
  persitent connections and how the dir hiearchy was not properly reset
  between files.

- David Byron's thoughts on a fixed Makefile in tests/ were applied.

- Jan Sundin reported a case where curl ignored a cookie that browsers don't,
  which turned up to be due to the number of dots in the 'domain'. I've now
  made curl follow the the original netscape cookie spec less strict on that
  part.

Daniel (4 August)
- Dirk Manske added cookie support for the experimental, hidden and still
  undocumented share feature!

- Mark Fletcher provided an excellent bug report that identified a problem
  with FOLLOWLOCATION and chunked transfer-encoding, as libcurl would not
  properly ignore the body contents of 3XX response that included the
  Location: header.

Early (6 August)
- Added option CURLOPT_FTP_CREATE_MISSING_DIRS
    This option will force the target file's path to be created if it
    does not already exist on the remote system.
 
  Files affected:
    - include/curl/curl.h
        Added option CURLOPT_FTP_CREATE_MISSING_DIRS
    - lib/ftp.c
        Added function ftp_mkd, which issues a MKD command
        Added function ftp_force_cwd, which attempts a CWD,
          and does a MKD and retries the CWD if the original CWD
          fails
        Modified ftp_perform() to call its change directory function
          through a pointer.  The pointer points to ftp_cwd by default,
          and is modified to point to ftp_force_cwd IFF
          data->set.ftp_create_missing_dirs is not 0.        
    - lib/url.c
        Modified Curl_setopt to recognize CURLOPT_FTP_CREATE_MISSING_DIRS
    - lib/urldata.h
        Added ftp_create_missing_dirs to struct UserDefined
       
- Minor Bugfix for CURLOPT_TIMECONDITION with FTP - if the file was not
  present to do the time comparison, it would fail.
  Files affected:
    - lib/ftp.c
        In ftp_perform(), the call to ftp_getfiletime() used to be followed
        by
	  if (result)
            return result;
        And then by the code that actually did the time comparison.
        The code that did the comparison handled the case where the filetime
        was not available (as indicated by info.filetime < 0 or set.timevalue 
        < 0), so I replaced the if (result) return result with a switch(result)
        that allows CURLE_FTP_COULDNT_RETR_FILE to fall through to the 
        normal time comparison.

Daniel (3 August)
- When proxy authentication is used in a CONNECT request (as used for all SSL
  connects and otherwise enforced tunnel-thru-proxy requests), the same
  authentication header is also wrongly sent to the remote host.

  This is a rather significant info leak. I've fixed it now and mailed a patch
  and warning to the mailing lists.

Daniel (1 August)
- David Byron provided a patch to make 7.10.6 build correctly with the
  compressed hugehelp.c source file.

Version 7.10.7-pre1 (31 July 2003)

Daniel (30 July)
- J<>rg M<>ller-Tolk updated the VC makefile.

- Daniel Noguerol made the ftp code output "Accept-Ranges: bytes" in similar
  style like other faked HTTP headers when NOBODY and HEADER are used. I
  updated two corresponding test cases too.

- Marty Kuhrt pointed out a compilation problem on VMS due to my having
  changed a type from long to time_t, and I'm now changing it back to work
  more portably...

  He also indicated that distributing the src/hugehelp.c in a compressed state
  like I acccidentally did may not be the smartest move... I've now fixed the
  distribute procudere to automaticly generate an uncompressed version when I
  make release archives.

Daniel (29 July)
- Gisle Vanem brought changes to the mkhelp script for the generation of the
  compressed help text on some platforms.

Version 7.10.6 (28 July 2003)

Daniel (28 July)
- Fran<61>ois Pons brought a patch that once again made curl deal with ftp and
  "double slash" as indicating the root directory. In the RFC1738-fix of April
  30, that ability was removed (since it is not the "right" way). So, starting
  now we can list the root dir of an ftp server both these ways:

    curl ftp://server.com/%2f  as well as
    curl ftp://server.com//

Daniel (24 July)
- Henry Bland pointed out that we included sys/resource.h without good reason
  in several source files. Without it included, QNX builds better...

- Andr<64>s Garc<72>a updated the mingw makefiles.

Daniel (23 July)
- Tracy Boehrer experienced DNS cache problems and did some nice debugging
  and tracking which made it easy for me to correct the problem and Tracy
  could verify that it did cure the problem! When re-using a connection we
  now make sure we don't re-use the 'connect_addr' struct.

- Daniel Kouril corrected the GSS-Negotiate code.

- Juan F. Codagnone provided fixes to allow curl to build fine on Windows
  again.

Daniel (22 July)
- Edited the curl/curl.h include file to build on Windows properly.

Daniel (21 July)
- Moved the proxy credentials from the SessionHandle struct to the connectdata
  struct, to make multiple proxy connections with differerent user names work.

- Adjusted the NTLM code to support proxy functionality.

- Made the krb4 stuff compile with the user+password fields moved.

Version 7.10.6-pre4 (21 July 2003)

Daniel (20 July)
- David Gardner pointed out in bug report 770755 that using the FTP command
  CWD with a blank argument is a bad idea and I made libcurl skip empty path
  segments starting now.

Daniel (18 July)
- Cris pointed out that my fix on July 16th didn't work fully. His pointing
  out this (and his patch) also made me realize that we have a very similar
  bug in the FTP connection re-use code. We must store a separate user and
  password field for each connection we keep (at least for FTP and HTTP+NTLM
  connections, so I made us do this unconditionally).

- Since NTLM authenticates connections instead of single requests, I had to
  re-arrange how we store the NTLM data and I had to improve the test suite to
  finally work properly with persistancy to make the NTLM tests run fine
  again. This also forced me to have to update lots of HTTP test cases.

Daniel (16 July)
- Cris Bailiff's bug report 768275 pointed out that using Basic auth with
  wrong user+password caused an endless loop. Fixed now. He also found out that
  we didn't properly authenticate connections with NTLM. Fixed too.

- Dan Winship provided fixes for the NTLM code.

Daniel (5 July)
- Doug Kaufman provided additional fixes for the DOS port.

Daniel (4 July)
- Rick Richardson pointed out that using setvbuf() to achive non-buffering
  on output is no-good for SCO Xenix and other unixes. We switched over to
  using plain fflush() instead.

- Dan Grayson pointed out that we set the CURL_CA_BUNDLE variable wrongly in
  the configure script, and I had to change some build stuff to make the new
  way work.

- Peter Sylvester's patch was applied that introduces the following:

   CURLOPT_SSL_CTX_FUNCTION to set a callback that gets called with the
   OpenSSL's ssl_ctx pointer passed in and allow a callback to act on it. If
   anything but CURLE_OK is returned, that will also be returned by libcurl
   all the way back. If this function changes the CURLOPT_URL, libcurl will
   detect this and instead go use the new URL.

   CURLOPT_SSL_CTX_DATA is a pointer you set to get passed to the callback set
   with CURLOPT_SSL_CTX_FUNCTION.

Daniel (1 July)
- David Byron provided a patch that allows a client to quit the test suite's
  HTTP server.

- Gisle Vanem found and patched a lib handle leak in the ldap code.

Daniel (25 June)
- More NTLM-improvements. Less code. Smaller packets back and forth.

Daniel (23 June)
- Eric Glass provided us with a better doc on NTLM details, and I added more
  comments and clarified the current code more. Using the new knowledge, we
  should be able to make the NTLM stuff work even better.
  Eric's original URL: http://davenport.sourceforge.net/ntlm.html
  Version stored and provided at curl site: http://curl.haxx.se/rfc/ntlm.html

- Fixed the minor compile problems pre3 had if built without GSSAPI and/or
  SSL.

Version 7.10.6-pre3 (19 June 2003)

Daniel (19 June)
- Made curl use curl_free() on memory returned by curl_getenv(), as this
  should theoreticly make it possibly to build and run curl and libcurl with
  different memory allocation schemes with no problems.

Daniel (18 June)
- Improved the mkhelp.pl a bit further to make a nicer hugehelp text and to
  include a better comment in the top for the gzip compressed version.

Daniel (17 June)
- CURLOPT_HTTPAUTH is now a bitmask, in which you set which authentication
  type(s) you want to use. If more than one is set, libcurl will use one of
  the selected one and the one it considers is more secure. Test case 67 and
  68 (for NTLM) were fixed and we've reduced a round-trip for specific --ntlm
  featches, and test case 69 and 70 were added for testing authentication
  "picking". --anyauth is the new command line tool option, and I also added
  --basic for completeness (that's the default type).

- Fixed the runtests.pl script to use the info provided by the new curl -V
  output.

- --enable-debug now sets the CURLDEBUG define instead of MALLOCDEBUG, as it
  is meant to be a generic debug conditional.

- curl_version_info() can now return CURL_VERSION_DEBUG as a feature bit, to
  indicate that the library was built with CURLDEBUG set.

- Ralph Mitchell found out that some web applications very badly uses white
  spaces in Location: redirects, and apparently IE is a browser (the only
  one?) that supports this abomination. Based on Ralph's patch, I added code
  that now attempts to replace white spaces with the proper "%20" or "+".
  Test case 40 and 42 were added to verify my changes.

- curl -V now also outputs a list of features the available library offers (if
  any).

- The curl_version() string now includes "GSS" if libcurl is built with GSSAPI
  support.

- David Orrell reported that libcurl still crashed when sending HUGE requests
  over HTTPS... I fixed.

Version 7.10.6-pre2 (16 June 2003)

Daniel (16 June)
- curl_version_info() now returns bitmasked information weather NTLM and
  GSSNEGOTIATE are supported, since it is doomed to vary on different
  installatiions.

- I remade the HTTP Digest code to use the MD5-code provided by OpenSSL if
  that is present, and only use our own MD5-code if it isn't.
  
Daniel (13 June)
- More NTLM help, fixes and patches from Cris Bailiff.

- Marty Kuhrt brought include fixes for making VMS builds warning-free.

Daniel (12 June)
- NTLM authentication works somewhat against the test servers provided by
  Mathias Axelsson and Cris Bailiff. Use by setting CURLOPT_HTTPAUTH to
  CURLAUTH_NTLM to libcurl, or --ntlm for the curl tool. Test case 67 and 68
  were added for this. NTLM-support requires OpenSSL.

- Dan Fandrich provided a patch, that granted that gzip and libz are available
  at build-time, compresses the hugehelp text in the curl command line and
  uncompresses it at request. Saves some ~60K in the final output executable.

Daniel (11 June)
- Long day of fighting the NTLM demons.

Daniel (10 June)
- Modified how to set auth type to libcurl. Now use CURLOPT_HTTPAUTH instead,
  and pick method. Supported ones currently are:
  CURLAUTH_BASIC     - default selection
  CURLAUTH_DIGEST    - formerly CURLOPT_HTTPDIGEST
  CURLAUTH_GSSNEGOTIATE

- Daniel Kouril added HTTP GSS-Negotiate authentication support, as defined in
  the IETF draft draft-brezak-spnego-http-04.txt. In use already by various
  Microsoft web applications. --negotiate is the new family member. To take
  advantage of this, you need one of these packages:

  o Heimdal Kerberos5               http://www.pdc.kth.se/heimdal/heimdal.html
  o GSSAPI from Globus                   http://www.globus.org/
  o GSSAPI libraries from MIT Kerberos5  http://web.mit.edu/kerberos/www/

- A missing ending bracket (']') while doing URL globbing could lead to a
  segfault. While fixing this, I also introduced better error reporting in the
  globbing code. (All this is application code outside libcurl.)

Daniel (6 June)
- David Orrell found out that sending a huge GET request over HTTPS could
  make libcurl fail and return an error code.

Daniel (2 June)
- Richard Bramante found out that "Content-Length: 0" was not properly used by
  libcurl if the response-headers indicated that the connection would be
  closed.

- David Byron's patch was applied, that makes the --progress-bar take the
  local size into account when doing resumed downloads.

- Feedback from Serge Semashko made me change the error message returned when
  CURLE_HTTP_RETURNED_ERROR is returned.

- Anonymous in bug report #745122 pointed out that we should really be using
  SSL_CTX_set_options(... SSL_OP_ALL) to work around flaws in existing SSL
  implementations.

Daniel (27 May)
- Andreas Ley and Rich Gray helped me point out that no version of HP-UX has
  the sys/select.h header file so including it unconditionally in curl/multi.h
  is not a good thing. Now we check for HPUX and avoid using that header on
  such systems.

- Rudy Koento experienced problems with curl's recent habit of POSTing data in
  two separate send() calls, first the headers and then the data. I've now
  made a fix that for static and known content that is less than 100K in size,
  everything is now sent in one single system call again. This is also better
  for network performance reasons.

- I modified the main makefile to not build the test suite and a few other
  unnecessary things by default. Now, the test suite is built when 'make test'
  is run.  This reduces build time for those who don't care for the test
  suite, and it also reduces confusion for people using platforms where the
  test suite build fails!

Daniel (26 May)
- Chris Lewis pointed out a flaw in the #ifdefs in curl/multi.h for Windows,
  which is now corrected.

- Jis Joy found another flaw in the SOCK5 code, as libcurl treated the socks5
  proxy a little too much like as if it was a http proxy.

Daniel (23 May)
- Ricardo Cadime found a socket leak when listing directories without
  contents. Test cases 144 and 145 were added to verify the fix.

- Rudy Koento found yet another problem when a HTTP server returns only a
  single-line of contents without any headers at all. libcurl then failed to
  count the data, thus returning error 52 "no contents". Test case 66 was
  added to verify that we now do right.

Version 7.10.6-pre1 (23 May 2003)

Daniel (23 May)
- Jis in bug report #741841, fixed a bug in the SOCKS5 proxy-using code.

Daniel (22 May)
- David Remahl set up a test-server for me providing Digest authentication,
  and I wrote the first working code that support it. The test suite was
  modified slightly as well to work better for it and --digest was added to
  the command line options (and CURLOPT_HTTPDIGEST to the library)...  RFC2617
  has all the gory details.

Daniel (21 May)
- David Balazic pointed out that curl_unescape() didn't check that %-codes
  were correctly followed by two hexadecimal digits when it unescape strings.
  Now, we do the check and only %XX codes are unescaped if the X letters are
  hexadecimals.

- Gisle Vanem made curl build with djgpp on DOS.

- Gisle Vanem improved the mkhelp.pl script to make a nicer manual that is
  shown with curl -M.

Daniel (20 May)
- Gisle Vanem provided a fix that makes libcurl more conservative, not
  expecting h_aliases of the hostent struct to always be non-NULL.

Daniel (19 May)
- As requested by Martin Michlmayr in Debian bug report #193630, libcurl now
  supports user name and password in the proxy environment variables. Added
  test case 63 to verify this.

Version 7.10.5 (19 May 2003)

Daniel (15 May)
- Changed the order for the in_addr_t testing, as 'unsigned long' seems to be
  a very common type inet_addr() returns.

Daniel (14 May)
- George Comninos provided a fix that calls the progress meter when waiting
  for FTP command responses take >1 second. It'll make applications more
  "responsive" even when dealing with very slow ftp servers.

Daniel (12 May)
- George Comninos pointed out that libcurl uploads had two quirks:
   o when using FTP PORT command, it used blocking sockets!
   o it could loop a long time without doing progress meter updates
  Both items are fixed now.

Daniel (9 May)
- Dan Fandrich changed CURLOPT_ENCODING to select all supported encodings if
  set to "".  This frees the application from having to know which encodings
  the library supports.

- Dan Fandrich pointed out we had three unnecessary files in CVS that is
  generated with libtoolize, so they're now removed and libtoolize is invoked
  accordingly in the buildconf script.

- Avery Fay found out that the CURLOPT_INTERFACE way of first checking if the
  given name is a network interface gave a real performance penalty on Linux,
  so now we more appropriately first check if it is an IP number and if so
  we don't check for a network interface with that name.

- CURLOPT_FTP_USE_EPRT added. Set this to FALSE to disable libcurl's attempts
  to use EPRT and LPRT before the traditional PORT command. The command line
  tool sets this option with '--disable-eprt'.

Version 7.10.5-pre2 (6 May 2003)

Daniel (6 May)
- Kevin Delafield reported another case where we didn't correctly check for
  EAGAIN but only EWOULDBLOCK, which caused badness on HPUX.

Daniel (4 May)
- Ben Greear noticed that the check for 'writable argv' exited the configure
  script when run for cross-compiling, which wasn't nice. Now it'll default to
  no and output a warning about the fact that it was not checked for.

Daniel (2 May)
- Added test case 62 and fixed some more on the cookie sending with a custom
  Host: header set.

Daniel (1 May)
- Andy Cedilnik fixed a few compiler warnings.

- Made the "SSL read error: 5" error message more verbose, by adding code that
  queries the OpenSSL library to fill in the error buffer.

Daniel (30 Apr)
- Added sys/select.h include in the curl/multi.h file, after having been
  reminded about this by Rich Gray.

- I made each test set its own server requirements, thus abandoning the
  previous system where the test number implied what server(s) to use for a
  specific test.

- David Balazic made curl more RFC1738-compliant for FTP URLs, by fixing so
  that libcurl now uses one CWD command for each path part. A bunch of test
  cases were fixed to work accordingly.

- Cookie fixes:

  A. Save domains in jars like Mozilla does. It means all domains set in
     Set-Cookie: headers are dot-prefixed.
  B. Save and use the 'tailmatch' field in the Mozilla/Netscape cookie jars
     (the second column).
  C. Reject cookies using illegal domains in the Set-Cookie: line. Concerns
     both domains with too few dots or domains that are outside the currently
     operating server host's domain.
  D. Set the path part by default to the one used in the request, if none was
     set in the Set-Cookie line.

  To make item C really good, I also made libcurl notice custom Host: headers
  and extract the host name set in there and use that as the host name for the
  site we're getting the cookies from. This allows user to specify a site's
  IP-address, but still be able to receive and send its cookies properly if
  you provide a valid Host: name for the site.

Daniel (29 Apr)
- Peter Kovacs provided a patch that makes the CURLINFO_CONNECT_TIME work fine
  when using the multi interface (too).

Version 7.10.5-pre1 (23 Apr 2003)

Daniel (23 Apr)
- Upgraded to libtool 1.5.

Daniel (22 Apr)
- Peter Sylvester pointed out that curl_easy_setopt() will always (wrongly)
  return CURLE_OK no matter what happens.

- Dan Fandrich fixed some gzip decompression bugs and flaws.

Daniel (16 Apr)
- Fixed minor typo in man page, reported in the Debian bug tracker.

Daniel (15 Apr)
- Fixed some FTP tests in the test suite that failed on my Solaris host, due
  to the config.h not being included before the system headers. When done that
  way, it did get a mixed sense of if big files are supported or not and then
  stat() and fstat() (as used in test case 505) got confused and failed to
  return a proper file size.

- Formposting a file using a .html suffix is now properly set to Content-Type:    text/html.

Daniel (14 Apr)
- Fixed the SSL error handling to return proper SSL error messages again, they
  broke in 7.10.4. I also attempt to track down CA cert problems and then
  return the CURLE_SSL_CACERT error code.

- The curl tool now intercepts the CURLE_SSL_CACERT error code and displays
  a fairly big and explanatory error message. Kevin Roth helped me out with
  the wording.

Daniel (11 Apr)
- Nic Hines provided a second patch for gzip decompression, and fixed a bug
  when deflate or gzip contents were downloaded using chunked encoding.

- Dan Fandrich made libcurl support automatic decompression of gzip contents
  (as an addition to the previous deflate support).

- I made the CWD command during FTP session consider all 2xy codes to be OK
  responses.

Daniel (10 Apr)
- Vlad Krupin fixed a URL parsing issue. URLs that were not using a slash
  after the host name, but still had "?" and parameters appended, as in
  "http://hostname.com?foobar=moo", were not properly parsed by libcurl.

Daniel (9 Apr)
- Made CURLOPT_TIMECONDITION work for FTP transfers, using the same syntax as
  for HTTP. This then made -z work for ftp transfers too. Added test case 139
  and 140 for verifying this.

- Getting the file date of an ftp file used the wrong time zone when
  displayed. It is supposedly always GMT. Added test case 141 for this.

- Made the test suite's FTP server support MDTM.

- The default DEBUGFUNCTION, as enabled with CURLOPT_VERBOSE now outputs
  CURLINFO_HEADER_IN data as well. The most notable effect from this is that
  using curl -v, you get to see the incoming "headers" as well. This is
  perhaps most useful when doing ftp.

Daniel (8 Apr)
- James Bursa fixed a flaw in the Content-Type extraction code, which missed
  the first letter if no space followed the colon.

- Magnus Nilsson pointed out that share.c was missing in the MSVC project
  file.

Daniel (6 Apr)
- Ryan Weaver provided a patch that makes the CA cert bundle not get installed
  anymore when 'configure --without-ssl' has been used.

Daniel (4 Apr)
- Martijn Broenland found another cases where a server application didn't
  like the boundary string used by curl when foing a multi-part/formpost. We
  modified the boundary string to look like the one IE uses, as this is
  probably gonna make curl work with more applications.

Daniel (3 Apr)
- Kevin Roth reported that a bunch of tests fails on cygwin. One set fails
  when using perl 5.8 (and they run fine with perl 5.6), and another set
  failed because of an artifact in the test suite's FTP server that I
  corrected. It turned out the FTP server code was still having a file opened
  while the main test script removed it and invoked the HTTP server that
  attempted to create the same file name of the file the FTP server kept open.
  This operation works fine on unix, but not on cygwin.

Version 7.10.4 (2 Apr 2003)

Daniel (1 Apr)
- Added test case 505 to exercise FTP upload with rename done with libcurl,
  and for that I had to extend the test suite's FTP server to deal with the
  RNFR and RNTO commands.

Daniel (31 Mar)
- Even more SSL config check modifications after Richard's testing.

Version 7.10.4-pre6 (31 Mar 2003)

Daniel (31 Mar)
- More fixes for the SSL session ID cache checks when SSL configs are changed
  between connections. Based on tests and talks with Richard Bramante.

- Guillaume Cottenceau provided a patch that added CURLOPT_UNRESTRICTED_AUTH.
  When enabled, it will prevent libcurl from limiting to which host it sends
  user+password to when following locations. By default, libcurl only sends
  name and password to the original host used in the first URL, but with this
  option set it will send the auth info to all hosts it follows location
  headers to. The new tool command line option for this is named
  "--location-trusted".

- Frankie Fong reported a problem with libcurl if you re-used an easy handle
  with a proxy, and you first made a https:// connction to a host and then
  switched to a http:// one to the same host. libcurl would then wrongly re-use
  the same connection for it and fail to get the second URL properly

Daniel (29 Mar)
- Dan Shearer's fix that makes curl complain if invoked with nothing but "curl
  -O" was applied.

Daniel (26 Mar)
- Bryan Kemp was friendly enough to lend me an account on his Redhat 9 box and
  I could fix the configure problems on redhat 8.1 and 9 in no time thanks to
  this. Thanks a bunch Bryan!

Daniel (25 Mar)
- Renamed configure.in to configure.ac

Version 7.10.4-pre5 (25 Mar 2003)

Daniel (25 Mar)
- Richard Bramante provided a fix for a handle re-use problem seen when you
  change options on an SSL-enabled connection between requests. Previously,
  changing peer verification or host verification and similar things was not
  taken into account when a connection were checked for re-use and thus
  enabling stricter check between requests on a re-used connection made no
  difference and the connection would thus be used erroneously.

Daniel (24 Mar)
- G<>tz Babin-Ebell pointed out that the ca-bundle.crt file contained a
  certificate from Trustcenter that was a demo certificate only that was never
  indended to be part of a CA bundle.

Daniel (21 Mar)
- Life is a mystery. Within a time period of 17 hours, Tim Pope and Michael
  Churchill filed one bug report each, both identifying problems with a second
  transfer when doing persistant transfers re-using a connection. Tim's one is
  #706624, labeled "Multiple uploads per handle fail" and Michael's #707003
  "Does not send Authorization: header when reusing connection". I could track
  both down to the same piece of logic and it turned out libcurl was not using
  new settings properly when re-using an existing connection. This concerned
  both uploading and downloading and involved exactly those pieces these two
  reports identified. This code has been this faulty since the day I
  introduced persistant connection support in libcurl, more than 2 years ago.

Daniel (20 Mar 2003)
- Five year anniversary. Today five years ago, the first ever curl release saw
  the light of day.

Daniel (17 Mar)
- Andy Cedilnik corrected flaws in some libcurl example-usage sources.

Daniel (16 Mar)
- Juan F. Codagnone reported that the fix from March 2nd was incomplete.

- Added code to the configure.in to check for select() argument types. I've
  not made any code use the results just yet though.

Daniel (15 Mar)
- Gisle Vanem provided two patches to build better on Windows.

- Adjusted the test suite code to better make sure that the server(s) required
  for a specific test is properly started before the test case is attempted.
  Many tests now run a lot faster than before.

Daniel (14 Mar)
- Another configure.in adjustment made the configure detect functions properly
  on HPUX now.

Daniel (13 Mar)
- Philippe Raoult fixed pre4-compile quirks for FreeBSD.

Version 7.10.4-pre4 (13 Mar 2003)

Daniel (13 Mar)
- Added a backup-check for functions that aren't found by AC_CHECK_FUNCS()
  as I believe some checks on HPUX need this. At least some of the info given
  to us by Rick Jones seemed to indicate this.

Daniel (12 Mar)
- Thomas Tonino found out that if you used the curl tool to do PUT operations
  as in 'curl www.foo.com/dir/ -T file' and the file name included for example
  space or other characters that don't belong in URLs, curl did not properly
  URL encode them before using them in the URL.

- Added an option to configure called --enable-libgcc that simply adds -lgcc
  to the LIBS variable, as this seems to be a common problem.

- I modified the configure.in file, so that the headers are now checked in an
  order of "viality". We must also make sure to use the "default headers"
  parameter to AC_CHECK_HEADERS() so that headers are checked with the proper
  prerequisites included (i.e all the major and generally important header
  files are included there by default). This might be what we need for various
  Sun, HP, AIX and Tru64 systems to behave good again on the header check
  front.

- Rick Jones pointed out a few compiler warnings on HP-UX that I addressed.

- I made the configure --help output nicer by using AC_HELP_STRING() a lot
  more.

Daniel (11 Mar)
- Christophe Demory fixed the socket sending code to work better on HP-UX
  when sending data to a socket that would block. It then returns EAGAIN, not
  EWOULDBLOCK.

- Richard Gorton improved the seeding function for systems without a good
  and reliable random source.

- Richard Gorton fixed a few warnings that popped up when you built curl
  using the Sun compiler on a 64bit SPARC platform.

- Martin C. Martin fixed a case where a connect failure using the multi
  interface didn't produce a human readable error string.

Daniel (10 Mar)
- Reverted ltmain.sh back to libtool 1.4.2 status again, as the 1.4.3 version
  broke the build on numerous platforms. It seems that libtool 1.4.3 puts some
  requirements on what versions of the other tools (autoconf + automake) that
  I am not familiar with and thus I couldn't fulfill at this point.

  Yes, this is more than mildly frustrating.

Daniel (7 Mar)
- Run libtoolize version 1.4.3.

Version 7.10.4-pre3 (4 Mar 2003)

Daniel (3 Mar)
- Added share.obj to the VC6 and Borland libcurl makefiles.

- Troels Walsted Hansen found and investigated a problem with libcurl on AIX,
  presumably only on 4.3 or later. gethostbyname_r() is not returning data
  that is possible to "keep" and cache the way libcurl does. But instead these
  versions of AIX uses a gethostbyname() that works thread-safely we can
  instead use the ordinary gethostbyname() and our pack_hostent() approach to
  achieve what we want. The configure script now attempts to detect AIX 4.3 or
  later to adjust for this.

Daniel (2 Mar)
- Juan F. Codagnone found a problem introduced in 7.10.3 when you first did a
  POST and then back to a GET using the same easy handle.

Daniel (28 Feb)
- Removed the strequal and strnequal defines from curl/curl.h header. They
  were never meant for the public header anyway. Philippe Raoult brought it
  up.

- James Bursa fixed the RISC OS build.

Daniel (27 Feb)
- Avery Fay pointed out the very misleading curl_multi_info_read man page, and
  I updated it to become more accurate.

- Salvatore Sorrentino found a problem with FTP downloading that turned out to
  be his FTP server returning size zero (0 bytes) when SIZE was used on a file
  while being in BINARY mode. We now make a second check for the actual size
  by scanning the RETR reply anyway, even if the SIZE command returned 0.

Daniel (26 Feb)
- Kyle Sallee reported a case where he would do a transfer that didn't update
  the progress meter properly. It turned out to be a case where libcurl would
  loop a little too eagerly in the tranfer loop, which isn't really good for
  the APIs, especially not the multi API.

Version 7.10.4-pre2 (24 Feb 2003)

Daniel (24 Feb)
- Kjetil Jacobsen found out that setting CURLOPT_MAXCONNECTS to a value higher
  than 5 could cause a segfault.

- I believe I fixed the 'Expect: 100-continue' behavior that has been broken
  for a while (I think since my change dated Dec 10 2002). When this header is
  used, libcurl should wait for a HTTP 100 (or timeout) before sending the
  post/put data.

Daniel (14 Feb)
- Matthew Clarke provided some info what to modify to make curl build
  flawlessly on AIX 3.2.5.

- Martin C. Martin found and fixed a problem in the multi interface when
  running on Windows and trying to connect to a port without a listener.

Daniel (13 Feb)
- Christopher R. Palmer fixed Curl_base64_encode() to deal with zeroes in the
  data to encode.

Daniel (4 Feb)
- Jean-Philippe added the first code that enables the 'share' system. This
  should now enable sharing of DNS data between two curl easy handles.

- Incorporated Nico Baggus' fixes to again compile flawlessly on VMS.

- James Bursa corrected a bad comment in the public include file curl/multi.h

- Peter Forret reported one of those error:00000000 cases in libcurl again
  when connecting to a HTTPS site, and this time I did discover some oddities
  in how curl reports SSL errors back. It could miss showing the actual error.

Version 7.10.4-pre1 (3 Feb 2003)

Daniel (3 Feb)
- Removed things in the docs saying capath doesn't work on Windows, as Julian
  Noble told us it works fine.

Daniel (31 Jan)
- Kevin Roth fixed the zlib build stuff in the Mingw32 makefile.

Daniel (30 Jan)
- Kevin Roth found out that curl on Windows always checked for the CA cert
  bundle using the environment variable and the path scan, even though
  -k/--insecure was used.

- Hamish Mackenzie pointed out that curl only did strict host name verifying
  if capath or cainfo was used. Now it'll always do it unless -k / --insecure
  is used!

- Pavel Cenek pointed out that the Content-Type extraction was done wrongly
  as the full string was not fetched. Added test case 57 to verify that curl
  does it right now.

Daniel (29 Jan)
- Jamie Wilkinson provided a patch that now makes curl attempt to clear out
  "sensitive" command line arguments so that they don't appear in ps outputs
  (only on platforms that allow writing to argv[]).

- John McGowan found out that the DEBUGFUNCTION could be called with bad
  arguments and thus cause the --trace outputs to go wrong.

- Removed all the emacs local variables from all files. Mats Lidell provided
  the new sample.emacs file (for a sample of what to include in your .emacs)
  and the curl-style.el that sets a better c-style for editing curl sources.

- Dave Halbakken found a problem with FTP downloads that could accidently
  return CURLE_PARTIAL_FILE when curl_easy_perform() was called with NOBODY
  set TRUE.

Daniel (27 Jan)
- The fopen.c example was flawed as Nick Humfrey noticed, and I fixed it to
  work again.

Daniel (24 Jan)
- Bertrand Demiddelaer found and fixed a memory leak (the content-type string)
  when following locations.

Daniel (22 Jan 2003)
- Ian Wilkes and Legoff Vincent both independently provided fixes for making
  curl/multi.h work properly when compiled with a C++ compiler.

Daniel (20 Jan 2003)
- Fixed 'buildconf' to check version number of the required tools before
  they're actually used.

- Wrote 'testcurl.sh', a script targeted for automatic and distributed curl
  tests on various platforms.

- David Thiel pointed out that the .netrc file was not being dealt with
  properly anymore. I broke this in the password prompting "fix".

- Markus F.X.J. Oberhumer patched libcurl to allocate the scratch buffer only
  on demand and thus we save 32KB in each curl handle that don't use that
  buffer. This need appeared when some people started using thousands of
  simultaneous curl handles... :-)

Daniel (16 Jan 2003)
- Markus Oberhumer fixed curl-config --cflags when the includedir was not
  /usr/include.

- Markus Oberhumer fixed CURLINFO_PRIVATE to properly return NULL if it was
  set to NULL!

Version 7.10.3 (14 Jan 2003)

Daniel (10 Jan 2003)
- Steve Oliphant pointed out that test case 105 did not work anymore and this
  was due to a missing fix for the password prompting.

Version 7.10.3-pre6 (10 Jan 2003)

Daniel (9 Jan 2003)
- Bryan Kemp pointed out that curl -u could not provide a blank password
  without prompting the user. It can now. -u username: makes the password
  empty, while -u username makes curl prompt the user for a password.

- Kjetil Jacobsen found a remaining connect problem in the multi interface on
  ipv4 systems (Linux only?), that I fixed and Kjetil verified that it fixed
  his problems.

- memanalyze.pl now reads a file name from the command line, and no longer
  takes the data on stdin as before.

Version 7.10.3-pre5 (9 Jan 2003)

Daniel (9 Jan 2003)
- Fixed tests/memanalyze.pl to work with file names that contain colons (as on
  Windows).
  
- Kjetil Jacobsen quickly pointed out that lib/share.h was missing...

Version 7.10.3-pre4 (9 Jan 2003)

Daniel (9 Jan 2003)
- Updated lib/share.c quite a bit to match the design document at
  http://curl.haxx.se/dev/sharing.txt a lot more.

  I'll try to update the document soonish. share.c is still not actually used
  by libcurl, but the API is slowly getting there and we can start
  implementing code that takes advantage of this system.

Daniel (8 Jan 2003)
- Updated share stuff in curl/curl.h, including data types, structs and
  function prototypes. The corresponding files in lib/ were also modified
  of course to remain compilable. Based on input from Jean-Philippe and also
  to make it more in line with the design document.

- Jean-Philippe Barrette-LaPierre patched a very trivial memory leak in
  curl_escape() that would happen when realloc() returns NULL...

- Matthew Blain provided feedback to make the --create-dirs stuff build
  properly on Windows.

- Fixed the #include in tests/libtest/first.c as Legoff Vincent pointed out.

Daniel (7 Jan 2003)
- Philippe Raoult provided a patch that now makes libcurl properly support
  wildcard checks for certificate names.

- Simon Liu added CURLOPT_HTTP200ALIASES, to let an application set other
  strings recognized as "HTTP 200" to allow http-like protocols to get
  downloaded fine by curl.

- Now using autoconf 2.57 and automake 1.7.2

- Doing "curl -I ftp://domain/non-existing-file" still outputed a date!
  Wayne Haigh reported.

- The error message is now written properly with a newline in the --trace
  file.

Daniel (6 Jan 2003)
- Sterling Hughes fixed a possible bug: previously, if you called
  curl_easy_perform and then set the global dns cache, the global cache
  wouldn't be used. Pointed out by Jean-Philippe Barrette-LaPierre.

- Matthew Blain's fixed the VC6 libcurl makefile to include better debug data
  on debug builds.
