                                  Changelog

Daniel (11 February 2005)
- Removed all uses of strftime() since it uses the localised version of the
  week day names and month names and servers don't like that.

Daniel (10 February 2005)
- Now the test script disables valgrind-testing when the test suite runs if
  libcurl is built shared. Otherwise valgrind only tests the shell that runs
  the wrapper-script named 'curl' that is a front-end to curl in this case.
  This should also fix the huge amount of reports of false positives when
  valgrind has identified leaks in (ba)sh and not in curl and people report
  that as curl bugs. Bug report #1116672 is one example.

  Also, the valgrind report parser has been adapted to check that at least one
  of the sources in a stack strace is one of (lib)curl's source files or
  otherwise it will not consider the problem to concern (lib)curl.

- Marty Kuhrt streamlined the VMS build.

Daniel (9 February 2005)
- David Byron fixed his SSL problems, initially mentioned here:
  http://curl.haxx.se/mail/lib-2005-01/0240.html. It turned out we didn't use
  SSL_pending() as we should.

- Converted lots of FTP code to a statemachine, so that the multi interface
  doesn't block while communicating commands-responses with an FTP server.

  I've added a comment like BLOCKING in the code on all spots I could find
  where we still have blocking operations. When we change curl_easy_perform()
  to use the multi interface, we'll also be able to simplify the code since
  there will only be one "internal interface".

  While doing this, I've now made CURLE_FTP_ACCESS_DENIED separate from the
  new CURLE_LOGIN_DENIED. The first one is now access denied to a function,
  like changing directory or retrieving a file, while the second means that we
  were denied login.

  The CVS tag 'before_ftp_statemachine' was set just before this went in, in
  case of future need.

- Gisle made the DICT code send CRLF and not just LF as the spec says so.

Daniel (8 February 2005)
- Gisle fixed problems when libcurl runs out of memory, and worked on making
  sure the proper error code is returned for those occations.

Daniel (7 February 2005)
- Maruko pointed out a problem with inflate decompressing exactly 64K
  contents.

Daniel (5 February 2005)
- Eric Vergnaud found a use of an uninitialised variable in the ftp when doing
  PORT on ipv6-enabled hosts.

- David Byron pointed out we could use BUFSIZE to read data (in
  lib/transfer.c) instead of using BUFSIZE -1.

Version 7.13.0 (1 February 2005)

Daniel (31 January 2005)
- Added Lars Nilsson's htmltitle.cc example

Daniel (30 January 2005)
- Fixed a memory leak when using the multi interface and the DO operation
  failed (as in test case 205).

- Fixed a valgrind warning for file:// operations.

- Fixed a valgrind report in the url globbing code for the curl command line
  tool.

- Bugfixed the parser that scans the valgrind report outputs (in runtests.pl).
  I noticed that it previously didn't detect and report the "Conditional jump
  or move depends on uninitialised value(s)" error. When I fixed this, I
  caught a few curl bugs with it. And then I had to spend time to make the
  test suite IGNORE these errors when OpenSSL is used since it produce massive
  amounts of valgrind warnings (but only of the "Conditional..." kind it
  seems). So, if a test that requires SSL is run, it ignores the
  "Conditional..." errors, and you'll get a "valgrind PARTIAL" output instead
  of "valgrind OK".

Daniel (29 January 2005)
- Using the multi interface, and doing a requsted a re-used connection that
  gets closed just after the request has been sent failed and did not re-issue
  a request on a fresh reconnect like the easy interface did. Now it does!

- Define CURL_MULTIEASY when building libcurl (lib/easy.c to be exact), to use
  my new curl_easy_perform() that uses the multi interface to run the
  request. It is a great testbed for the multi interface and I believe we
  shall do it this way for real in the future when we have a successor to
  curl_multi_fdset(). I've used this approach to detect and fix several of the
  recent multi-interfaces issues.

- Adjusted the KNOWN_BUGS #17 fix a bit more since the FTP code also did some
  bad assumptions.

- multi interface: when a request is denied due to "Maximum redirects
  followed" libcurl leaked the last Location: URL.

- Connect failures with the multi interface was often returned as "connect()
  timed out" even though the reason was different.

Daniel (28 January 2005)
- KNOWN_BUGS #17 fixed. A DNS cache entry may not remain locked between two
  curl_easy_perform() invokes. It was previously unlocked at disconnect, which
  could mean that it remained locked between multiple transfers. The DNS cache
  may not live as long as the connection cache does, as they are separate.

  To deal with the lack of DNS (host address) data availability in re-used
  connections, libcurl now keeps a copy of the IP adress as a string, to be
  able to show it even on subsequent requests on the same connection.

  The problem could be made to appear with this stunt:

  1. create a multi handle
  2. add an easy handle
  3. fetch a URL that is persistent (leaves the connection alive)
  4. remove the easy handle from the multi
  5. kill the multi handle
  6. create a multi handle
  7. add the same easy handle to the new multi handle
  8. fetch a URL from the same server as before (re-using the connection)

- Stephen More pointed out that CURLOPT_FTPPORT and the -P option didn't work
  when built ipv6-enabled. I've now made a fix for it. Writing test cases for
  custom port hosts turned too tricky so unfortunately there's none.

Daniel (25 January 2005)
- Ian Ford asked about support for the FTP command ACCT, and I discovered it
  is present in RFC959... so now (lib)curl supports it as well. --ftp-account
  and CURLOPT_FTP_ACCOUNT set the account string. (The server may ask for an
  account string after PASS have been sent away. The client responds
  with "ACCT [account string]".) Added test case 228 and 229 to verify the
  functionality. Updated the test FTP server to support ACCT somewhat.

- David Shaw contributed a fairly complete and detailed autoconf test you can
  use to detect libcurl and setup variables for the protocols the installed
  libcurl supports: docs/libcurl/libcurl.m4

Daniel (21 January 2005)
- Major FTP third party transfer overhaul.

  These four options are now obsolete: CURLOPT_SOURCE_HOST,
  CURLOPT_SOURCE_PATH, CURLOPT_SOURCE_PORT (this option didn't work before)
  and CURLOPT_PASV_HOST.

  These two options are added: CURLOPT_SOURCE_URL and CURLOPT_SOURCE_QUOTE.

  The target-side didn't use the proper path with RETR, and thus this only
  worked correctly in the login path (i.e without doing any CWD). The source-
  side still uses a wrong path, but the fix for this will need to wait. Verify
  the flaw by using a source URL with included %XX-codes.

  Made CURLOPT_FTPPORT control weather the target operation should use PORT
  (or not). The other side thus uses passive (PASV) mode.

  Updated the ftp3rdparty.c example source to use the updated options.

  Added support for a second FTP server in the test suite. Named... ftp2.
  Added test cases 230, 231 and 232 as a few first basic tests of very simple
  3rd party transfers.

  Changed the debug output to include 'target' and 'source' when a 3rd party
  is being made, to make it clearer what commands/responses came on what
  connection.

  Added three new command line options: --3p-url, --3p-user and --3p-quote.

  Documented the command line options and the curl_easy_setopt options related
  to third party transfers.

  (Temporarily) disabled the ability to re-use an existing connection for the
  source connection. This is because it needs to force a new in case the
  source and target is the same host, and the host name check is trickier now
  when the source is identified with a full URL instead of a plain host name
  like before.

  TODO (short-term) for 3rd party transfers: quote support. The options are
  there, we need to add test cases to verify their functionality.

  TODO (long-term) for 3rd party transfers: IPv6 support (EPRT and EPSV etc)
  and SSL/TSL support.

Daniel (20 January 2005)
- Philippe Hameau found out that -Q "+[command]" didn't work, although some
  code was written for it. I fixed and added test case 227 to verify it.
  The curl.1 man page didn't mention the '+' so I added it.

Daniel (19 January 2005)
- Stephan Bergmann made libcurl return CURLE_URL_MALFORMAT if an FTP URL
  contains %0a or %0d in the user, password or CWD parts. (A future fix would
  include doing it for %00 as well - see KNOWN_BUGS for details.) Test case
  225 and 226 were added to verify this
