Update to 7.16.3:

Version 7.16.3 (25 June 2007)

Daniel S (23 June 2007)
- As reported by "Tro" in http://curl.haxx.se/mail/lib-2007-06/0161.html and
  http://curl.haxx.se/mail/lib-2007-06/0238.html, libcurl didn't properly do
  no-body requests on FTP files on re-used connections properly, or at least
  it didn't provide the info back in the header callback properly in the
  subsequent requests.

Daniel S (21 June 2007)
- Gerrit Bruchhäuser pointed out a warning that the Intel(R) Thread Checker
  tool reports and it was indeed a legitimate one and it is one fixed. It was
  a use of a share without doing the proper locking first.

Daniel S (20 June 2007)
- Adam Piggott filed bug report #1740263
  (http://curl.haxx.se/bug/view.cgi?id=1740263). Adam discovered that when
  getting a large amount of URLs with curl, they were fetched slower and
  slower... which turned out to be because the --libcurl data collecting which
  wrongly always was enabled, but no longer is...

Daniel S (18 June 2007)
- Robson Braga Araujo filed bug report #1739100
  (http://curl.haxx.se/bug/view.cgi?id=1739100) that mentioned that libcurl
  could not actually list the contents of the root directory of a given FTP
  server if the login directory isn't root. I fixed the problem and added
  three test cases (one is disabled for now since I identified KNOWN_BUGS #44,
  we cannot use --ftp-method nocwd and list ftp directories).

Daniel S (14 June 2007)
- Shmulik Regev:

  I've encountered (and hopefully fixed) a problem involving proxy CONNECT
  requests and easy handles state management. The problem isn't simple to
  reproduce since it depends on socket state. It only manifests itself when
  working with non-blocking sockets.

  Here is the scenario:

  1. in multi_runsingle the easy handle is in the CURLM_STATE_WAITCONNECT and
  calls Curl_protocol_connect

  2. in Curl_proxyCONNECT, line 1247, if the socket isn't ready the function
  returns and conn->bits.tunnel_connecting is TRUE

  3. when the call to Curl_protocol_connect returns the protocol_connect flag
  is false and the easy state is changed to CURLM_STATE_PROTOCONNECT which
  isn't correct if a proxy is used.  Rather CURLM_STATE_WAITPROXYCONNECT
  should be used.

  I discovered this while performing an HTTPS request through a proxy (squid)
  on my local network. The problem caused openssl to fail as it read the proxy
  response to the CONNECT call ('HTTP/1.0 Established') rather than the SSL
  handshake (the exact openssl error was 'wrong ssl version' but this isn't
  very important)

- Dave Vasilevsky filed bug report #1736875
  (http://curl.haxx.se/bug/view.cgi?id=1736875) almost simultanouesly as Dan
  Fandrich mentioned a related build problem on the libcurl mailing list:
  http://curl.haxx.se/mail/lib-2007-06/0131.html. Both problems had the same
  reason: the definitions of the POLL* defines and the pollfd struct in the
  libcurl code was depending on HAVE_POLL instead of HAVE_SYS_POLL_H.

Daniel S (13 June 2007)
- Tom Regner provided a patch and worked together with James Housley, so now
  CURLOPT_FTP_CREATE_MISSING_DIRS works for SFTP connections as well as FTP
  ones.

- Rich Rauenzahn filed bug report #1733119
  (http://curl.haxx.se/bug/view.cgi?id=1733119) and we collaborated on the
  fix.  The problem is that for 64bit HPUX builds, several socket-related
  functions would still assume int (32 bit) arguments and not socklen_t (64
  bit) ones.

Daniel S (12 June 2007)
- James Housley brought his revamped SSH code that is state-machine driven to
  really take advantage of the now totally non-blocking libssh2 (in CVS).

Dan F (8 June 2007)
- Incorporated Daniel Black's test706 and test707 SOCKS test cases.

- Fixed a few problems when starting the SOCKS server.

- Reverted some recent changes to runtests.pl that weren't compatible with
  perl 5.0.

- Fixed the test harness so that it actually kills the ssh being used as
  the SOCKS server.

Daniel S (6 June 2007)
- -s/--silent can now be used to toggle off the silence again if used a second
  time.

Daniel S (5 June 2007)
- Added Daniel Black's work that adds the first few SOCKS test cases. I also
  fixed two minor SOCKS problems to make the test cases run fine.

Daniel S (31 May 2007)
- Feng Tu made (lib)curl support "upload" resuming work for file:// URLs.

Daniel S (30 May 2007)
- I modified the 10-at-a-time.c example to transfer 500 downloads in parallel
  with a c-ares enabled build only to find that it crashed miserably, and this
  was due to some select()isms left in the code. This was due to API
  restrictions in c-ares 1.3.x, but with the upcoming c-ares 1.4.0 this is no
  longer the case so now libcurl runs much better with c-ares and the multi
  interface with > 1024 file descriptors in use.

  Extra note: starting now we require c-ares 1.4.0 for asynchronous name
  resolves.

- Added CURLMOPT_MAXCONNECTS which is a curl_multi_setopt() option for setting
  the maximum size of the connection cache maximum size of the multi handle.

Daniel S (27 May 2007)
- When working with a problem Stefan Becker had, I found an off-by-one buffer
  overwrite in Curl_select(). While fixing it, I also improved its performance
  somewhat by changing calloc to malloc and breaking out of a loop earlier
  (when possible).

Daniel S (25 May 2007)
- Rob Crittenden fixed bug #1705802
  (http://curl.haxx.se/bug/view.cgi?id=1705802), which was filed by Daniel
  Black identifying several FTP-SSL test cases fail when we build libcurl with
  NSS for TLS/SSL. Listed as #42 in KNOWN_BUGS.

Daniel S (24 May 2007)
- Song Ma filed bug report #1724016
  (http://curl.haxx.se/bug/view.cgi?id=1724016) noticing that downloading
  glob-ranges for TFTP was broken in CVS. Fixed now.

- 'mytx' in bug report #1723194 (http://curl.haxx.se/bug/view.cgi?id=1723194)
  pointed out that the warnf() function in the curl tool didn't properly deal
  with the cases when excessively long words were used in the string to chop
  up.

Daniel S (22 May 2007)
- Andre Guibert de Bruet fixed a memory leak in the function that verifies the
  peer's name in the SSL certificate when built for OpenSSL. The leak happens
  for libcurls with CURL_DOES_CONVERSIONS enabled that fail to convert the CN
  name from UTF8. He also fixed a leak when PKCS #12 parsing failed.

Daniel S (18 May 2007)
- Feng Tu reported that curl -w did wrong on TFTP transfers in bug report
  #1715394 (http://curl.haxx.se/bug/view.cgi?id=1715394), and the
  transfer-related info "variables" were indeed overwritten with zeroes
  wrongly and have now been adjusted. The upload size still isn't accurate.

Daniel S (17 May 2007)
- Feng Tu pointed out a division by zero error in the TFTP connect timeout
  code for timeouts less than five seconds, and also provided a fix for it.
  Bug report #1715392 (http://curl.haxx.se/bug/view.cgi?id=1715392)

Dan F (16 May 2007)
- Added support for compiling under Minix 3.1.3 using ACK.

Dan F (14 May 2007)
- Added SFTP directory listing test case 613.

- Added support for quote commands before a transfer using SFTP and test
  case 614.

- Changed the post-quote commands to occur after the transferred file is
  closed.

- Allow SFTP quote commands chmod, chown, chgrp to set a value of 0.

Dan F (9 May 2007)
- Kristian Gunstone fixed a problem where overwriting an uploaded file with
  sftp didn't truncate it first, which would corrupt the file if the new
  file was shorter than the old.

Dan F (8 May 2007)
- Added FTPS test cases 406 and 407

Daniel S (8 May 2007)
- CURLE_FTP_COULDNT_STOR_FILE is now known as CURLE_UPLOAD_FAILED. This is
  because I just made SCP uploads return this value if the file size of
  the upload file isn't given with CURLOPT_INFILESIZE*. Docs updated to
  reflect this news, and a define for the old name was added to the public
  header file.

Daniel S (7 May 2007)
- James Bursa fixed a bug in the multi handle code that made the connection
  cache grow a bit too much, beyond the normal 4 * easy_handles.

Daniel S (2 May 2007)
- Anders Gustafsson remarked that requiring CURLOPT_HTTP_VERSION set to 1.0
  when CURLOPT_HTTP200ALIASES is used to avoid the problem mentioned below is
  not very nice if the client wants to be able to use _either_ a HTTP 1.1
  server or one within the aliases list... so starting now, libcurl will
  simply consider 200-alias matches the to be HTTP 1.0 compliant.

- Tobias Rundström reported a problem they experienced with xmms2 and recent
  libcurls, which turned out to be the 25-nov-2006 change which treats HTTP
  responses without Content-Length or chunked encoding as without bodies. We
  now added the conditional that the above mentioned response is only without
  body if the response is HTTP 1.1.

- Jeff Pohlmeyer improved the hiperfifo.c example to use the
  CURLMOPT_TIMERFUNCTION callback option.

- Set the timeout for easy handles to expire really soon after addition or
  when CURLM_CALL_MULTI_PERFORM is returned from curl_multi_socket*/perform,
  to make applications using only curl_multi_socket() to properly function
  when adding easy handles "on the fly". Bug report and test app provided by
  Michael Wallner.

Dan F (30 April 2007)
- Improved the test harness to allow running test servers on other than
  the default port numbers, allowing more than one test suite to run
  simultaneously on the same host.

Daniel S (28 April 2007)
- Peter O'Gorman fixed libcurl to not init GnuTLS as early as we did before,
  since it then inits libgcrypt and libgcrypt is being evil and EXITS the
  application if it fails to get a fine random seed. That's really not a nice
  thing to do by a library.

- Frank Hempel fixed a curl_easy_duphandle() crash on a handle that had
  been removed from a multi handle, and then fixed another flaw that prevented
  curl_easy_duphandle() to work even after the first fix - the handle was
  still marked as using the multi interface.

Daniel S (26 April 2007)
- Peter O'Gorman found a problem with SCP downloads when the downloaded file
  was 16385 bytes (16K+1) and it turned out we didn't properly always "suck
  out" all data from libssh2. The effect being that libcurl would hang on the
  socket waiting for data when libssh2 had in fact already read it all...

Dan F (25 April 2007)
- Added support in runtests.pl for "!n" test numbers to disable individual
  tests.  Changed -t to only keep log files around when -k is specified,
  to have the same behaviour as without -t.

Daniel S (25 April 2007)
- Sonia Subramanian brought our attention to a problem that happens if you set
  the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection
  in the connection cache is closed to make room for the new one when you call
  curl_easy_perform(). It would then wrongly free range-related data in the
  connection close funtion.

Yang Tse (25 April 2007)
- Steve Little fixed compilation on VMS 64-bit mode

Daniel S (24 April 2007)
- Robert Iakobashvili made the 'master_buffer' get allocated first once it is
  can/will be used as it then makes the common cases save 16KB of data for each
  easy handle that isn't used for pipelining.

Dan F (23 April 2007)
- Added <postcheck> support to the test harness.

- Added tests 610-612 to test more SFTP post-quote commands.

Daniel S (22 April 2007)
- Song Ma's warning if -r/--range is given with a "bad" range, also noted in
  the man page now.

- Daniel Black filed bug #1705177
  (http://curl.haxx.se/bug/view.cgi?id=1705177) where --without-ssl
  --with-gnutl outputs a warning about SSL not being enabled even though GnuTLS
  was found and used.

Daniel S (21 April 2007)
- Daniel Black filed bug #1704675
  (http://curl.haxx.se/bug/view.cgi?id=1704675) identifying a double-free
  problem in the SSL-dealing layer, telling GnuTLS to free NULL credentials on
  closedown after a failure and a bad #ifdef for NSS when closing down SSL.

Yang Tse (20 April 2007)
- Save one call to curlx_tvnow(), which calls gettimeofday(), in each of
  Curl_socket_ready(), Curl_poll() and Curl_select() when these are called
  with a zero timeout or a timeout value indicating a blocking call should
  be performed.

Daniel S (18 April 2007)
- James Housley made SFTP uploads use libssh2's non-blocking API

- Prevent the internal progress meter from updating more frequently than once
  per second.

Dan F (17 April 2007)
- Added test cases 296, 297 and 298 to test --ftp-method handling

Daniel S (16 April 2007)
- Robert Iakobashvil added curl_multi_socket_action() to libcurl, which is a
  function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the
  socket that it passes in. This gives a significant performance boost as it
  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().

  I added a define in the public curl/multi.h header file that will make your
  existing application automatically use curl_multi_socket_action() instead of
  curl_multi_socket() when you recompile. But of course you'll get better
  performance if you adjust your code manually and actually pass in the
  correct action bitmask to this function.

Daniel S (14 April 2007)
- Jay Austin added "DH PARAMETERS" to the stunnel.pem certificate for the test
  suite to make stunnel run better in some (most?) environments.

Dan F (13 April 2007)
- Added test cases 294 and 295 to test --ftp-account handling

- Improved handling of out of memory in ftp.

Yang Tse (13 April 2007)
- Fix test case 534 which started to fail 2007-04-13 due to the existance
  of a new host on the net with the same silly domain the test was using
  for a host which was supposed not to exist.

Daniel S (12 April 2007)
- Song Ma found a memory leak in the if2ip code if you pass in an interface
  name longer than the name field of the ifreq struct (typically 6 bytes), as
  then it wouldn't close the used dummy socket. Bug #1698974
  (http://curl.haxx.se/bug/view.cgi?id=1698974)
