                                  Changelog

Daniel (12 February 2007)
- Rob Crittenden added support for NSS (Network Security Service) for the
  SSL/TLS layer. http://www.mozilla.org/projects/security/pki/nss/

  This is the fourth supported library for TLS/SSL that libcurl supports!

- Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent
  to the debug callback.

- Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and
  CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's
  internal decoding of content or transfer encoded content. This may be
  preferable in cases where you use libcurl for proxy purposes or similar. The
  command line tool got a --raw option to disable both at once.
  
- Jeff Pohlmeyer fixed a flaw in curl_multi_add_handle() when adding a handle
  that has an easy handle present in the "closure" list pending closure.

Daniel (6 February 2007)
- Regular file downloads wiht SFTP and SCP are now done using the non-blocking
  API of libssh2, if the libssh2 headers seem to support them. This will make
  SCP and SFTP much more responsive and better libcurl citizens when used with
  the multi interface etc.

Daniel (5 February 2007)
- Michael Wallner added support for CURLOPT_TIMEOUT_MS and
  CURLOPT_CONNECTTIMEOUT_MS that, as their names suggest, do the timeouts with
  millisecond resolution. The only restriction to that is the alarm()
  (sometimes) used to abort name resolves as that uses full seconds. I fixed
  the FTP response timeout part of the patch.

  Internally we now count and keep the timeouts in milliseconds but it also
  means we multiply set timeouts with 1000. The effect of this is that no
  timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
  equals 24.86 days.  We probably couldn't before either since the code did
  *1000 on the timeout values on several places already.

Daniel (3 February 2007)
- Yang Tse fixed the cookie expiry date in several test cases that started to
  fail since they used "1 feb 2007"...

- Manfred Schwarb reported that socks5 support was broken and help us pinpoint
  the problem. The code now tries harder to use httproxy and proxy where
  apppropriate, as not all proxies are HTTP...

Version 7.16.1 (29 January 2007)

Daniel (29 January 2007)
- Michael Wallner reported that when doing a CONNECT with a custom User-Agent
  header, you got _two_ User-Agent headers in the CONNECT request...! Added
  test case 287 to verify the fix.

Daniel (28 January 2007)
- curl_easy_reset() now resets the CA bundle path correctly.

- David McCreedy fixed the Curl command line tool for HTTP on non-ASCII
  platforms.

Daniel (25 January 2007)
- Added the --libcurl [file] option to curl. Append this option to any
  ordinary curl command line, and you will get a libcurl-using source code
  written to the file that does the equivalent operation of what your command
  line operation does!

Dan F (24 January 2007)
- Fixed a dangling pointer problem that prevented the http_proxy environment
  variable from being properly used in many cases (and caused test case 63
  to fail).

Daniel (23 January 2007)
- David McCreedy did NTLM changes mainly for non-ASCII platforms:

  #1
  There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT
  defined.  I noticed this while testing various configurations.  Line 867 of
  the current http_ntlm.c is a closing bracket for an if/else pair that only
  gets compiled in if USE_NTLM2SESSION is defined.  But this closing bracket
  wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was
  defined.  Lines 198 and 140 of my patch wraps that closing bracket in an
  #ifdef USE_NTLM2SESSION.

  #2
  I noticed several picky compiler warnings when DEBUG_ME is defined.  I've
  fixed them with casting.  By the way, DEBUG_ME was a huge help in
  understanding this code.

  #3
  Hopefully the last non-ASCII conversion patch for libcurl in a while.  I
  changed the "NTLMSSP" literal to hex since this signature must always be in
  ASCII.

  Conversion code was strategically added where necessary.  And the
  Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c
  creates are NOT translated on non-ASCII platforms.

Dan F (22 January 2007)
- Converted (most of) the test data files into genuine XML.  A handful still
  are not, due mainly to the lack of support for XML character entities
  (e.g. & => &amp; ).  This will make it easier to validate test files using
  tools like xmllint, as well as to edit and view them using XML tools.

Daniel (16 January 2007)
- Armel Asselin improved libcurl to behave a lot better when an easy handle
  doing an FTP transfer is removed from a multi handle before completion. The
  fix also fixed the "alive counter" to be correct on "premature removal" for
  all protocols.

Dan F (16 January 2007)
- Fixed a small memory leak in tftp uploads discovered by curl's memory leak
  detector.  Also changed tftp downloads to URL-unescape the downloaded
  file name.

Daniel (14 January 2007)
- David McCreedy provided libcurl changes for doing HTTP communication on
  non-ASCII platforms. It does add some complexity, most notably with more
  #ifdefs, but I want to see this supported added and I can't see how we can
  add it without the extra stuff added.

- Setting CURLOPT_COOKIELIST to "ALL" when no cookies at all was present,
  libcurl would crash when trying to read a NULL pointer.

Daniel (12 January 2007)
- Toby Peterson found a nasty bug that prevented (lib)curl from properly
  downloading (most) things that were larger than 4GB on 32 bit systems.  Matt
  Witherspoon helped as narrow down the problem.

Daniel (5 January 2007)
- Linus Nielsen Feltzing introduced the --ftp-ssl-ccc command line option to
  curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it
  will make libcurl shutdown SSL/TLS after the authentication is done on a
  FTP-SSL operation.

Daniel (4 January 2007)
- David McCreedy made changes to allow base64 encoding/decoding to work on
  non-ASCII platforms.

Daniel (3 January 2007)
- Matt Witherspoon fixed the flaw which made libcurl 7.16.0 always store
  downloaded data in two buffers, just to be able to deal with a special HTTP
  pipelining case. That is now only activated for pipelined transfers. In
  Matt's case, it showed as a considerable performance difference,

Daniel (2 January 2007)
- Victor Snezhko helped us fix bug report #1603712
  (http://curl.haxx.se/bug/view.cgi?id=1603712) (known bug #36) --limit-rate
  (CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE) are broken
  on Windows (since 7.16.0, but that's when they were introduced as previous
  to that the limiting logic was made in the application only and not in the
  library). It was actually also broken on select()-based systems (as apposed
  to poll()) but we haven't had any such reports. We now use select(), Sleep()
  or delay() properly to sleep a while without waiting for anything input or
  output when the rate limiting is activated with the easy interface.

- Modified libcurl.pc.in to use Libs.private for the libs libcurl itself needs
  to get built static. It has been mentioned before and was again brought to
  our attention by Nathanael Nerode who filed debian bug report #405226
  (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405226).

Daniel (29 December 2006)
- Make curl_easy_duphandle() set the magic number in the new handle.

Daniel (22 December 2006)
- Robert Foreman provided a prime example snippet showing how libcurl would
  get confused and not acknowledge the 'no_proxy' variable properly once it
  had used the proxy and you re-used the same easy handle. I made sure the
  proxy name is properly stored in the connect struct rather than the
  sessionhandle/easy struct.

- David McCreedy fixed a bad call to getsockname() that wrongly used a size_t
  variable to point to when it should be a socklen_t.

- When setting a proxy with environment variables and (for example) running
  'curl [URL]' with a URL without a protocol prefix, curl would not send a
  correct request as it failed to add the protocol prefix.

Daniel (21 December 2006)
- Robson Braga Araujo reported bug #1618359
  (http://curl.haxx.se/bug/view.cgi?id=1618359) and subsequently provided a
  patch for it: when downloading 2 zero byte files in a row, curl 7.16.0
  enters an infinite loop, while curl 7.16.1-20061218 does one additional
  unnecessary request.

  Fix: During the "Major overhaul introducing http pipelining support and
  shared connection cache within the multi handle." change, headerbytecount
  was moved to live in the Curl_transfer_keeper structure. But that structure
  is reset in the Transfer method, losing the information that we had about
  the header size. This patch moves it back to the connectdata struct.

Daniel (16 December 2006)
- Brendan Jurd provided a fix that now prevents libcurl from getting a SIGPIPE
  during certain conditions when GnuTLS is used.
