Update to 7.16.0:

Version 7.16.0 (30 October 2006)

Daniel (25 October 2006)
- Fixed CURLOPT_FAILONERROR to return CURLE_HTTP_RETURNED_ERROR even for the
  case when 401 or 407 are returned, *IF* no auth credentials have been given.
  The CURLOPT_FAILONERROR option is not possible to make fool-proof for 401
  and 407 cases when auth credentials is given, but we've now covered this
  somewhat more.

  You might get some amounts of headers transferred before this situation is
  detected, like for when a "100-continue" is received as a response to a
  POST/PUT and a 401 or 407 is received immediately afterwards.

  Added test 281 to verify this change.

Daniel (23 October 2006)
- Ravi Pratap provided a major update with pipelining fixes. We also no longer
  re-use connections (for pipelining) before the name resolving is done.

Daniel (21 October 2006)
- Nir Soffer made the tests/libtest/Makefile.am use a proper variable for all
  the single test applications' link and dependences, so that you easier can
  override those from the command line when using make.

- Armel Asselin separated CA cert verification problems from problems with
  reading the (local) CA cert file to let users easier pinpoint the actual
  problem. CURLE_SSL_CACERT_BADFILE (77) is the new libcurl error code.

Daniel (18 October 2006)
- Removed the "protocol-guessing" for URLs with host names starting with FTPS
  or TELNET since they are practically non-existant. This leaves us with only
  three different prefixes that would assume the protocol is anything but
  HTTP, and they are host names starting with "ftp.", "dict." or "ldap.".

Daniel (17 October 2006)
- Bug report #1579171 pointed out code flaws detected with "prefast", and they
  were 1 - a too small memory clear with memset() in the threaded resolver and
  2 - a range of potentially bad uses of the ctype family of is*() functions
  such as isdigit(), isalnum(), isprint() and more. The latter made me switch
  to using our own set of these functions/macros using uppercase letters, and
  with some extra set of crazy typecasts to avoid mistakingly passing in
  negative numbers to the underlying is*() functions.

- With Jeff Pohlmeyer's help, I fixed the expire timer when using
  curl_multi_socket() during name resolves with c-ares and the LOW_SPEED
  options now work fine with curl_multi_socket() as well.

Daniel (16 October 2006)
- Added a check in configure that simply tries to run a program (not when
  cross-compiling) in order to detect problems with run-time libraries that
  otherwise would occur when the sizeof tests for curl_off_t would run and
  thus be much more confusing to users. The check of course should run after
  all lib-checks are done and before any other test is used that would run an
  executable built for testing-purposes.

Dan F (13 October 2006)
- The tagging of application/x-www-form-urlencoded POST body data sent
  to the CURLOPT_DEBUGFUNCTION callback has been fixed (it was erroneously
  included as part of the header).  A message was also added to the
  command line tool to show when data is being sent, enabled when
  --verbose is used.

Daniel (12 October 2006)
- Starting now, adding an easy handle to a multi stack that was already added
  to a multi stack will cause CURLM_BAD_EASY_HANDLE to get returned.

- Jeff Pohlmeyer has been working with the hiperfifo.c example source code,
  and while doing so it became apparent that the current timeout system for
  the socket API really was a bit awkward since it become quite some work to
  be sure we have the correct timeout set.

  Jeff then provided the new CURLMOPT_TIMERFUNCTION that is yet another
  callback the app can set to get to know when the general timeout time
  changes and thus for an application like hiperfifo.c it makes everything a
  lot easier and nicer. There's a CURLMOPT_TIMERDATA option too of course in
  good old libcurl tradition.

  Jeff has also updated the hiperfifo.c example code to use this news.

Daniel (9 October 2006)
- Bogdan Nicula's second test case (posted Sun, 08 Oct 2006) converted to test
  case 535 and it now runs fine. Again a problem with the pipelining code not
  taking all possible (error) conditions into account.

Daniel (6 October 2006)
- Bogdan Nicula's hanging test case (posted Wed, 04 Oct 2006) was converted to
  test case 533 and the test now runs fine.

Daniel (4 October 2006)
- Dmitriy Sergeyev provided an example source code that crashed CVS libcurl
  but that worked nicely in 7.15.5. I converted it into test case 532 and
  fixed the problem.

Daniel (29 September 2006)
- Removed a few other no-longer present options from the header file.

- Support for FTP third party transfers was removed. Here's why:

  o The recent multi interface changes broke it and the design of the 3rd party
    transfers made it very hard to fix the problems
  o It was still blocking and thus nasty for the multi interface
  o It was a lot of extra code for a very rarely used feature
  o It didn't use the same code as for "plain" FTP transfers, so it didn't work
    fine for IPv6 and it didn't properly re-use connections and more
  o There's nobody around who's willing to work on and improve the existing
    code

  This does not mean that third party transfers are banned forever, only that
  they need to be done better if they are to be re-added in the future.

  The CURLOPT_SOURCE_* options are removed from the lib and so are the --3p*
  options from the command line tool. For this reason, I also bumped the
  version info for the lib.

Daniel (28 September 2006)
- Reported in #1561470 (http://curl.haxx.se/bug/view.cgi?id=1561470), libcurl
  would crash if a bad function sequence was used when shutting down after
  using the multi interface (i.e using easy_cleanup after multi_cleanup) so
  precautions have been added to make sure it doesn't any more - test case 529
  was added to verify.

Daniel (27 September 2006)
- The URL in the cookie jar file is now changed since it was giving a 404.
  Reported by Timothy Stone. The new URL will take the visitor to a curl web
  site mirror with the document.

Daniel (24 September 2006)
- Bernard Leak fixed configure --with-gssapi-libs.

- Cory Nelson made libcurl use the WSAPoll() function if built for Windows
  Vista (_WIN32_WINNT >= 0x0600)

Daniel (23 September 2006)
- Mike Protts added --ftp-ssl-control to make curl use FTP-SSL, but only
  encrypt the control connection and use the data connection "plain".

- Dmitriy Sergeyev provided a patch that made the SOCKS[45] code work better
  as it now will read the full data sent from servers. The SOCKS-related code
  was also moved to the new lib/socks.c source file.

Daniel (21 September 2006)
- Added test case 531 in an attempt to repeat bug report #1561470
  (http://curl.haxx.se/bug/view.cgi?id=1561470) that is said to crash when an
  FTP upload fails with the multi interface. It did not, but I made a failed
  upload still assume the control connection to be fine.

Daniel (20 September 2006)
- Armel Asselin fixed problems when you gave a proxy URL with user name and
  empty password or no password at all. Test case 278 and 279 were added to
  verify.

Daniel (12 September 2006)
- Added docs/examples/10-at-a-time.c by Michael Wallner

- Added docs/examples/hiperfifo.c by Jeff Pohlmeyer

Daniel (11 September 2006)
- Fixed my breakage from earlier today so that doing curl_easy_cleanup() on a
  handle that is part of a multi handle first removes the handle from the
  stack.

- Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL
  session-ID re-use on demand since there obviously are broken servers out
  there that misbehave with session-IDs used.

- Jeff Pohlmeyer presented a *multi_socket()-using program that exposed a
  problem with it (SIGSEGV-style). It clearly showed that the existing
  socket-state and state-difference function wasn't good enough so I rewrote
  it and could then re-run Jeff's program without any crash. The previous
  version clearly could miss to tell the application when a handle changed
  from using one socket to using another.

  While I was at it (as I could use this as a means to track this problem
  down), I've now added a 'magic' number to the easy handle struct that is
  inited at curl_easy_init() time and cleared at curl_easy_cleanup() time that
  we can use internally to detect that an easy handle seems to be fine, or at
  least not closed or freed (freeing in debug builds fill the area with 0x13
  bytes but in normal builds we can of course not assume any particular data
  in the freed areas).

Daniel (9 September 2006)
- Michele Bini fixed how the hostname is put in NTLM packages. As servers
  don't expect fully qualified names we need to cut them off at the first dot.

- Peter Sylvester cleaned up and fixed the getsockname() uses in ftp.c. Some
  of them can be completetly removed though...

Daniel (6 September 2006)
- Ravi Pratap and I have implemented HTTP Pipelining support. Enable it for a
  multi handle using CURLMOPT_PIPELINING and all HTTP connections done on that
  handle will be attempted to get pipelined instead of done in parallell as
  they are performed otherwise.

  As a side-effect from this work, connections are now shared between all easy
  handles within a multi handle, so if you use N easy handles for transfers,
  each of them can pick up and re-use a connection that was previously used by
  any of the handles, be it the same or one of the others.

  This separation of the tight relationship between connections and easy
  handles is most noticable when you close easy handles that have been used in
  a multi handle and check amount of used memory or watch the debug output, as
  there are times when libcurl will keep the easy handle around for a while
  longer to be able to close it properly. Like for sending QUIT to close down
  an FTP connection.

  This is a major change.

Daniel (4 September 2006)
- Dmitry Rechkin (http://curl.haxx.se/bug/view.cgi?id=1551412) provided a
  patch that while not fixing things very nicely, it does make the SOCKS5
  proxy connection slightly better as it now acknowledges the timeout for
  connection and it no longer segfaults in the case when SOCKS requires
  authentication and you did not specify username:password.

Daniel (31 August 2006)
- Dmitriy Sergeyev found and fixed a multi interface flaw when using asynch
  name resolves. It could get stuck in the wrong state.

Gisle (29 August 2006)
- Added support for other MS-DOS compilers (desides djgpp). All MS-DOS
  compiler now uses the same config.dos file (renamed to config.h by
  make). libcurl now builds fine using Watcom and Metaware's High-C
  using the Watt-32 tcp/ip-stack.

Daniel (29 August 2006)
- David McCreedy added CURLOPT_SOCKOPTFUNCTION and CURLOPT_SOCKOPTDATA to
  allow applications to set their own socket options.

Daniel (25 August 2006)
- Armel Asselin reported that the 'running_handles' counter wasn't updated
  properly if you removed a "live" handle from a multi handle with
  curl_multi_remove_handle().

Daniel (22 August 2006)
- David McCreedy fixed a remaining mistake from the August 19 TYPE change.

- Peter Sylvester pointed out a flaw in the AllowServerConnect() in the FTP
  code when doing pure ipv6 EPRT connections.

Daniel (19 August 2006)
- Based on a patch by Armel Asselin, the FTP code no longer re-issues the TYPE
  command on subsequent requests on a re-used connection unless it has to.

- Armel Asselin fixed a crash in the FTP code when using SINGLECWD mode and
  files in the root directory.

- Andrew Biggs pointed out a "Expect: 100-continue" flaw where libcurl didn't
  send the whole request at once, even though the Expect: header was disabled
  by the application. An effect of this change is also that small (< 1024
  bytes) POSTs are now always sent without Expect: header since we deem it
  more costly to bother about that than the risk that we send the data in
  vain.

Daniel (9 August 2006)
- Armel Asselin made the CURLOPT_PREQUOTE option work fine even when
  CURLOPT_NOBODY is set true. PREQUOTE is then run roughly at the same place
  in the command sequence as it would have run if there would've been a
  transfer.

Daniel (8 August 2006)
- Fixed a flaw in the "Expect: 100-continue" treatment. If you did two POSTs
  on a persistent connection and allowed the first to use that header, you
  could not disable it for the second request.

Daniel (7 August 2006)
- Domenico Andreolfound a quick build error which happened because
  src/config.h.in was not a proper duplcate of lib/config.h.in which it
  should've been and this was due to the maketgz script not doing the cp
  properly.
