                                  Changelog

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*().

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)

Version 7.16.2 (11 April 2007)

Yang Tse (10 April 2007)
- Ravi Pratap provided some fixes for HTTP pipelining

- configure script will ignore --enable-sspi option for non-native Windows.

Daniel S (9 April 2007)
- Nick Zitzmann did ssh.c cleanups

Daniel S (3 April 2007)
- Rob Jones fixed better #ifdef'ing for a bunch of #include lines.

Daniel S (2 April 2007)
- Nick Zitzmann made the CURLOPT_POSTQUOTE option work for SFTP as well. The
  accepted commands are as follows:

  chgrp (gid) (path)
    Changes the group ID of the file or directory at (path) to (gid). (gid)
    must be a number.

  chmod (perms) (path)
    Changes the permissions of the file or directory at (path) to
    (perms). (perms) must be a number in the format used by the chmod Unix
    command.

  chown (uid) (path)
    Changes the user ID of the file or directory at (path) to (uid). (uid)
    must be a number.

  ln (source) (dest)
    Creates a symbolic link at (dest) that points to the file located at
    (source).

  mkdir (path)
    Creates a new directory at (path).

  rename (source) (dest)
    Moves the file or directory at (source) to (dest).

  rm (path)
    Deletes the file located at (path).

  rmdir (path)
    Deletes the directory located at (path). This command will raise an error
    if the directory is not empty.

  symlink (source) (dest)
    Same as ln.

Daniel S (1 April 2007)
- Robert Iakobashvili made curl_multi_remove_handle() a lot faster when many
  easy handles are added to a multi handle, by avoiding the looping over all
  the handles to find which one to remove.

- Matt Kraai provided a patch that makes curl build on QNX 6 fine again.

Daniel S (31 March 2007)
- Fixed several minor issues detected by the coverity.com scanner.

- "Pixel" fixed a problem that appeared when you used -f with user+password
  embedded in the URL.

Dan F (29 March 2007)
- Don't tear down the ftp connection if the maximum filesize was exceeded
  and added tests 290 and 291 to check.

- Added ftps upload and SSL required tests 401 and 402.

- Send an EOF message before closing an SCP channel, as recommended by
  RFC4254. Enable libssh2 tracing when ssh debugging is turned on.

Yang Tse (27 March 2007)
- Internal function Curl_select() renamed to Curl_socket_ready()

  New Internal wrapper function Curl_select() around select (2), it
  uses poll() when a fine poll() is available, so now libcurl can be
  built without select() support at all if a fine poll() is available.

Daniel S (25 March 2007)
- Daniel Johnson fixed multi code to traverse the easy handle list properly.
  A left-over bug from the February 21 fix.

Dan F (23 March 2007)
- Added --pubkey option to curl and made --key also work for SCP/SFTP,
  plus made --pass work on an SSH private key as well.

- Changed the test harness to attempt to gracefully shut down servers
  before resorting to the kill -9 hammer.

- Added test harness infrastructure to support scp/sftp tests, using
  OpenSSH as the server.

- Fixed a memory leak when specifying a proxy with a file: URL.

Yang Tse (20 March 2007)
- Fixed: When a signal was caught awaiting for an event using Curl_select()
  or Curl_poll() with a non-zero timeout both functions would restart the
  specified timeout. This could even lead to the extreme case that if a
  signal arrived with a frecuency lower to the specified timeout neither
  function would ever exit.

  Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
  Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
  defined both functions will return as soon as a signal is caught. Use it
  at your own risk, all calls to these functions in the library should be
  revisited and checked before fully supporting this feature.

Yang Tse (19 March 2007)
- Bryan Henderson fixed the progress function so that it can get called more
  frequently allowing same calling frecuency for the client progress callback.
  
Dan F (15 March 2007)
- Various memory leaks plugged and NULL pointer fixes made in the ssh code.

Daniel (15 March 2007)
- Nick made the curl tool accept globbing ranges that only is one number, i.e
  you can now use [1-1] without curl complaining.

Daniel (10 March 2007)
- Eygene Ryabinkin:

  The problem is the following: when we're calling Curl_done and it decides to
  keep the connection opened ('left intact'), then the caller is not notified
  that the connection was done via the NULLifying of the pointer, so some easy
  handle is keeping the pointer to this connection.

  Later ConnectionExists can select such connection for reuse even if we're
  not pipelining: pipeLen is zero, so the (pipeLen > 0 && !canPipeline) is
  false and we can reuse this connection for another easy handle. But thus the
  connection will be shared between two easy handles if the handle that wants
  to take the ownership is not the same as was not notified of the connection
  was done in Curl_done. And when some of these easy handles will get their
  connection really freed the another one will still keep the pointer.

  My fix was rather trivial: I just added the NULLification to the 'else'
  branch in the Curl_done. My tests with Git and ElectricFence showed no
  problems both for HTTP pulling and cloning. Repository size is about 250 Mb,
  so it was a considerable amount of Curl's work.

Dan F (9 March 2007)
- Updated the test harness to add a new "crypto" feature check and updated the
  appropriate test case to use it.  For now, this is treated the same as the
  "SSL" feature because curl doesn't list it separately.

Daniel (9 March 2007)
- Robert Iakobashvili fixed CURLOPT_INTERFACE for IPv6.

- Robert A. Monat improved the maketgz and VC6/8 generating to set the correct
