                                  Changelog

Daniel S (1 April 2007)
- 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
  machine type too.

- Justin Fletcher fixed a file descriptor leak in the curl tool when trying to
  upload a file it couldn't open. Bug #1676581
  (http://curl.haxx.se/bug/view.cgi?id=1676581)

Dan F (9 March 2007)
- Updated the test harness to check for protocol support before running each
  test, fixing KNOWN_BUGS #11.

Dan F (7 March 2007)
- Reintroduced (after a 3 year hiatus) an FTPS test case (400) into the test
  harness.  It is very limited as it supports only ftps:// URLs with
  --ftp-ssl-control specified, which implicitly encrypts the control
  channel but not the data channels.  That allows stunnel to be used with
  an unmodified ftp server in exactly the same way that the test https
  server is set up.

Dan F (7 March 2007)
- Honour --ftp-ssl-control on ftps:// URLs to allow encrypted control and
  unencrypted data connections.

Dan F (6 March 2007)
- Fixed a couple of improper pointer uses detected by valgrind in test
  cases 181 & 216.

Daniel (2 March 2007)
- Robert A. Monat and Shmulik Regev helped out to fix the new */Makefile.vc8
  makefiles that are included in the source release archives, generated from
  the Makefile.vc6 files by the maketgz script. I also modified the root
  Makefile to have a VC variable that defaults to vc6 but can be overridden to
  allow it to be used for vc8 as well. Like this:

    nmake VC=vc8 vc

Daniel (27 February 2007)
- Hang Kin Lau found and fixed: When I use libcurl to connect to an https
  server through a proxy and have the remote https server port set using the
  CURLOPT_PORT option, protocol gets reset to http from https after the first
  request.
 
  User defined URL was modified internally by libcurl and subsequent reuse of
  the easy handle may lead to connection using a different protocol (if not
  originally http).
 
  I found that libcurl hardcoded the protocol to "http" when it tries to
  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
  follows and it's working fine so far

Daniel (25 February 2007)
- Adam D. Moss made the HTTP CONNECT procedure less blocking when used from
  the multi interface. Note that it still does a part of the connection in a
  blocking manner.

Daniel (23 February 2007)
- Added warning outputs if the command line uses more than one of the options
  -v, --trace and --trace-ascii, since it could really confuse the user.
  Clarified this fact in the man page.

Daniel (21 February 2007)
- Ravi Pratap provided work on libcurl making pipelining more robust and
  fixing some bugs:
  o Don't mix GET and POST requests in a pipeline
  o Fix the order in which requests are dispatched from the pipeline
  o Fixed several curl bugs with pipelining when the server is returning
    chunked encoding:
    * Added states to chunked parsing for final CRLF
    * Rewind buffer after parsing chunk with data remaining
    * Moved chunked header initializing to a spot just before receiving
      headers

Daniel (20 February 2007)
- Linus Nielsen Feltzing changed the CURLOPT_FTP_SSL_CCC option to handle
  active and passive CCC shutdown and added the --ftp-ssl-ccc-mode command
  line option.

Daniel (19 February 2007)
- Ian Turner fixed the libcurl.m4 macro's support for --with-libcurl.

- Shmulik Regev found a memory leak in re-used HTTPS connections, at least
  when the multi interface was used.

- Robson Braga Araujo made passive FTP transfers work with SOCKS (both 4 and
  5).

Daniel (18 February 2007)
- Jeff Pohlmeyer identified two problems: first a rather obscure problem with
  the multi interface and connection re-use that could make a
  curl_multi_remove_handle() ruin a pointer in another handle.

  The second problem was less of an actual problem but more of minor quirk:
  the re-using of connections wasn't properly checking if the connection was
  marked for closure.

Daniel (16 February 2007)
- Duncan Mac-Vicar Prett and Michal Marek reported problems with resetting
  CURLOPT_RANGE back to no range on an easy handle when using FTP.
