Version 7.22.0 (13 Sep 2011)

Daniel Stenberg (13 Sep 2011)
- RELEASE-NOTES: ready for 7.22.0

- codestyle: minor whitespace fix

- [Jeff Pohlmeyer brought this change]

  polarssl: build with PolarSSL-1.0.0
  
  With this fix, it should work for PolarSSL-1.0.0 (and SVN-1091 trunk)
  and retain compatibility with earlier versions. (Tested with 0.14.1)
  
  PolarSSL still doesn't play nicely with curl's CA bundle (we discussed
  this before) but I was at least able to retrieve the
  https://www.gmail.com/ login page using a modified ca-certificates.crt
  file with all 3 versions of PolarSSL.

- BUGS: spellfixed, slightly reformatted for web looks
  
  Reported by: Jeff Pohlmeyer

Dan Fandrich (12 Sep 2011)
- Document NTLM winbind options (and caveats)

Daniel Stenberg (12 Sep 2011)
- BUGS: renumbered to look better in the web version

- BUGS: revamped bug report documentation

Yang Tse (12 Sep 2011)
- Mention that BSD-style lwIP TCP/IP stack support on Windows is experimental.

- ftp.c: fix socket leak torture tests detected 2011-08-30
  
  Also fix inappropriate error handling when sending ftp EPRT or PORT commands.

Daniel Stenberg (11 Sep 2011)
- TODO: remove 4 entries, add one new
  
  Zero-copy and "Avoid having to remove/readd handles" are not really
  features we think are worthwhile to add. Removed.
  
  SRP features have been added already, removed.
  
  11.9 IPv6 addresses with globbing added

- spell-checked comments

- TODO-RELEASE: postpone the remainders
  
  There's three pending bug fixes but there's no time left so let's
  try to get them fixed for next release...

Guenter Knauf (11 Sep 2011)
- Updated makefiles to latest libssh2.

Yang Tse (10 Sep 2011)
- urlglob.c: fix OOM handling

- ftp.c: fix ftp active connects which got broken with commit fdf157abdf

- runtests.pl: replace TAB with spaces

- test harness: revert needless commit 0a5bbb2ac1
  
  https, ftps and ssh servers allowed start up time back to previous values

- ssh.c: revert needless commit 7b7c45879e

Daniel Stenberg (9 Sep 2011)
- RELEASE-NOTES: synced with 303c90074d4c
  
  Five more bugfixes, one more contributor

- tcpnodelay: rename variable
  
  Renamed the variable from 'proto' to 'level' simply because it is not
  protocol you set but level and that is the name of the argument used in
  man pages and the POSIX documentation of the setsockopt function.

Guenter Knauf (8 Sep 2011)
- Avoid ftruncate() static define with MinGW64.

Yang Tse (8 Sep 2011)
- libssh2: use calloc as alloc function for libssh2 versions older than 1.3
  
  This workarounds old libssh2 versions not properly initializing
  some ssh session variables, which would trigger memory debuggers
  warnings on memory being used without having been initialized.

Daniel Stenberg (8 Sep 2011)
- [Adriano Meirelles brought this change]

  Curl_speedcheck: don't mistakenly clear Curl_expire()
  
  The current version of speedcheck.c may disable timeout by setting zero
  to Curl_expire. Which is fine using the curl_multi_perform, because it
  recheck all timeout internals, but when using custom event poller (like
  hiperfifo.c) it may keep stalle connection forever.

Yang Tse (8 Sep 2011)
- lib582.c: fix segfault triggered when torture testing test case 582

Daniel Stenberg (7 Sep 2011)
- ftp_state_use_port: minor code indent fix

- checksrc: detect "}else" uses as well

- getinmemory.c: use better argument names for write callback

Yang Tse (7 Sep 2011)
- ssh.c: fix memory leaks triggered upon OOM or other failures

- test case 583: ensure that test failures don't go unnoticed - follow-up

- test suite: libtest header inclusion cleanup - follow-up
  
  Adjust tests/libtest/Makefile.inc and remove a couple of unused headers from
  tests/libtest/lib583.c

- test case 583: ensure that test failures don't go unnoticed

- test suite: libtest header inclusion cleanup
  
  Added missing memoryTracking to test cases 560 and 583. If this triggers
  leak detection on these, it only means that previously it was going unnoticed.

- fix bool variables checking and assignment

- pingpong.c: avoid a memmove call in function Curl_pp_vsendf

- fix bool variables checking and assignment

- test suite: use test case specific netrc file names

Guenter Knauf (4 Sep 2011)
- Fixed final message output.

Daniel Stenberg (4 Sep 2011)
- TODO-RELEASE: deleteing five issues due to no response
  
  No feedback and no updates, removing these issues

Yang Tse (4 Sep 2011)
- setup_once.h cleanup and sync

Guenter Knauf (4 Sep 2011)
- Fix to skip untrusted certs.

- Added SPNEGO to MinGW makefiles.

Yang Tse (4 Sep 2011)
- NTLM WB: fix file descriptor leak upon OOM condition

- revert changes not intended to be pushed with commit 6b75d2c2

- fix a bunch of MSVC compiler warnings

Guenter Knauf (3 Sep 2011)
- Updated dependecies versions.

- Some MinGW makefile tweaks for MinGW64.

- Changed MinGW to use own winidn prototypes.

Dan Fandrich (2 Sep 2011)
- Fix NTLM winbind support to pass the torture tests
  
  Calling sclose() both in the child and the parent fools the
  socket leak detector into thinking it's been closed twice.
  Calling close() in the child instead overcomes this problem. It's
  not as portable as the sclose() macro, but this code is highly
  POSIX-specific, anyway.

Yang Tse (2 Sep 2011)
- MemoryTracking: fix logging of free() calls done where Curl_safefree is called
  
  Just internal stuff...
  
  Curl_safefree is now a macro defined in memdebug.h instead of a function
  prototyped in url.h and implemented in url.c, so inclusion of url.h is no
  longer required in order to simply use Curl_safefree.
  
  Provide definition of macro WHILE_FALSE in setup_once.h in order to allow
  other macros such as DEBUGF and DEBUGASSERT, and code using it, to compile
  without 'conditional expression is constant' warnings.
  
  The WHILE_FALSE stuff fixes 150+ MSVC compiler warnings.

- transfer.c: fix parentheses/braces placement for vi/emacs delimiter matching

- transfer.c: fix loadhostpairs() OOM handling

- test harness: https, ftps and ssh servers allowed start up time increased 33%

- hostip.c: return immediately from Curl_resolv_timeout() upon expired timeout.
  
  Ensure existing logic in Curl_resolv_timeout() is not subverted upon getting a
  negative timeout from resolve_server(). The timeout in resolve_server() could
  be checked to avoid calling Curl_resolv_timeout() with an expired timeout, but
  fixing this in this way allows existing logic in resolve_server() to be kept
  unchanged.

- ftp.c: fix some leaks torture tests detected 2011-08-30 - follow-up
  
  follow-up for commit d20408e8

- test harness: fix detection of test harness client knownhosts file
  
  Regenerate curl's tests client knownhosts file also when, somehow,
  this file is empty.

- test harness: fix detection of test harness host and client key files
  
  Regenerate curl's tests host and client key files also when, somehow,
  any of these files are empty.

  Preprocessor symbol USE_NTLM_SSO renamed to WINBIND_NTLM_AUTH_ENABLED.
  curl's 'long' option 'ntlm-sso' renamed to 'ntlm-wb'.

Yang Tse (24 Aug 2011)
- [Steve Holme brought this change]

  SMTP authentication: fix ordering of preferred authentication method
  
  Fixed the order of the preferred SMTP authentication method to:
  AUTH CRAM-MD5, AUTH LOGIN then AUTH PLAIN.
  
  AUTH PLAIN should be the last as it slightly more insecure than AUTH LOGIN
  as the username and password are sent together - there is no handshaking
  between the client and server like there is with AUTH LOGIN.

- base64: fix Curl_base64_encode and Curl_base64_decode interfaces
  
  Previous interfaces for these libcurl internal functions did not allow to tell
  apart a legitimate zero size result from an error condition. These functions
  now return a CURLcode indicating function success or otherwise specific error.
  Output size is returned using a pointer argument.
  
  All usage of these two functions, and others closely related, has been adapted
  to the new interfaces. Relative error and OOM handling adapted or added where
  missing. Unit test 1302 also adapted.

- [Steve Holme brought this change]

  http NTLM: remaining bits from 0001-Moved-ntlm-[...]-curl_ntlm-mod_3.patch
  
  * Added function comments:
      - Curl_ntlm_decode_type2_message
      - Curl_ntlm_create_type1_message
      - Curl_ntlm_create_type3_message
  
  * Modification of ntlm processing state to NTLMSTATE_TYPE2 is now done
    only when Curl_ntlm_decode_type2_message() has fully succeeded.

- runtests.pl: option -gw for single test windowed debugging (where possible)

- zlib: ensure user provided memory functions are used by zlib, when given
  
  As a bonus, this lets our MemoryTracking subsystem track zlib operations.
  And also fixes a shortcut some zlib 1.2.x versions took using malloc()
  instead of calloc(), which would trigger memory debuggers warnings on
  memory being used without having been initialized.

Daniel Stenberg (21 Aug 2011)
- main: fix segfault
  
  Follow-up to commit 5eb2396cd as that wasn't complete.
  
  At times HEADERFUNCTION+HEADERDATA was set only to have only HEADERDATA
  set in the subsequent loop which could cause a NULL to get sent as
  userdata to 'header_callback' which wasn't made to handle that.
  
  Now HEADERFUNCTION is explicitly set to NULL if it isn't set to the
  callback.

Yang Tse (21 Aug 2011)
- MemoryTracking: adjust initialization calling - followup

- tcpconnect: follow-up commit after b998d95b
  
  As I modified conn->bits.tcpconnect to become an array that holds one
  bool for each potential connection all uses of that struct field must
  index it correctly.

- ssh.c: add PATH_MAX definition for WIN32

Daniel Stenberg (19 Aug 2011)
- connect: set TIMER_CONNECT
  
  When connecting, make sure TIMER_CONNECT is set.

- test573: fix the keywords

- FTP: fix proxy connect race condition
  
  When using the multi interface, a SOCKS proxy, and a connection that
  wouldn't immediately consider itself connected (which my Linux tests do
  by default), libcurl would be tricked into doing _two_ connects to the
  SOCKS proxy when it setup the data connection and then of course the
  second attempt would fail miserably and cause error.
  
  This problem is a regression that was introduced by commit
  4a42e5cdaa344755 that was introduced in the 7.21.7 release.

Yang Tse (17 Aug 2011)
- MemoryTracking: adjust curl_domalloc() and curl_dofree() memory filling
  
  Until 2011-08-17 libcurl's Memory Tracking feature also performed
  automatic malloc and free filling operations using 0xA5 and 0x13
  values. Our own preinitialization of dynamically allocated memory
  might be useful when not using third party memory debuggers, but
  on the other hand this would fool memory debuggers into thinking
  that all dynamically allocated memory is properly initialized.
  
  As a default setting, libcurl's Memory Tracking feature no longer
  performs preinitialization of dynamically allocated memory on its
  own. If you know what you are doing, and really want to retain old
  behavior, you can achieve this compiling with preprocessor symbols
  CURL_MT_MALLOC_FILL and CURL_MT_FREE_FILL defined with appropriate
  values.

- MemoryTracking: make curl_docalloc() call calloc() avoiding our zero fill

- MSVC makefiles: provide SSH build targets

- test572: fixed
  
  Two problems were fixed:
  
  GET_PARAMETER responses that have no body must be 204 response or
  properly set length to 0.
  
  One of the <data> sections had the wrong content-length for its
  GET_PARAMETER response.
  
  Enabled test 572 again.

- Curl_pgrsStartNow: clear all flags but HIDE
  
  As bug 3385258 pointed out but I missed up the fix for. This is another

Yang Tse (14 Aug 2011)
- http NTLM: add curl_ntlm.c to Symbian's libcurl.mmp

- http NTLM: fix 8 compiler warnings
  
  Strict splitting of http_ntlm.[ch] may trigger 8 compiler warnings when
  building with some compilers and strict compiler warnings enabled, depending
  on other specific configuration options some could get triggered or not.
  
  Seven are related with 'unused function parameters' and another one with
  'var may be used before its value is set'.

- http NTLM: split http_ntlm.[ch] between http_ntlm.[ch] and curl_ntlm.[ch]
  
  For modularity purposes, huge chunks of NTLM existing code is transformed into
  functions to allow future internal code reuse.
  
  Resulting three new libcurl private functions:
  
   - Curl_ntlm_create_type1_message()
   - Curl_ntlm_create_type3_message()
   - Curl_ntlm_decode_type2_message()
  
  Changing static ntlm_sspi_cleanup() into non-static Curl_ntlm_sspi_cleanup()
  
  This 'refactoring' has been prepared by previous commits to allow that this
  specific one does not introduce any change to existing code. All existing
  goodness and badness previous to this commit should remain the same once it is
  applied, the only difference should be that existing code is moved into
  functions.
  
  Given the quite big portions of code being moved around, and the importance of
  change traceability, this commit has been done in such a way that it is
  possible to perform a three-way diff from initial http_ntlm.[ch] to resulting
  http_ntlm.[ch] and curl_ntlm.[ch] to actually verify that no functional change
  is introduced here.
  
  Notice that Steve Holme has provided several patches, but these included this
  refactoring along with 'extra' fixes. I really wanted this 'clean' refactoring
  done first, in order to allow discussion or committing of 'extra' fixes on a
  case by case basis, so, I had to bite the bullet ;-)
  
  Comments, line adjustments, compiler warning fixes, whatever, may follow
  afterwards.

Yang Tse (4 Aug 2011)
- BSD-style lwIP TCP/IP stack support:
  
  Allow compilation of libcurl and curl using BSD-style lwIP on Win32.
  
  In order to compile libcurl and curl with this support it is necessary
  to edit files lib/config-win32.h and src/config-win32.h and uncomment
  a line to make definition of preprocessor symbol USE_LWIPSOCK visible.
  
  Afterwards you can compile as usual.
  
  In order to use compiled library with BSD-style lwIP TCP/IP stack in
  your program it is mandatory that you include lwIP header file <lwip/opt.h>
  before including <curl/curl.h> or <curl/multi.h>
  
  Compilation has been verified with lwIP 1.4.0 and contrib-1.4.0 from:
  
  http://download.savannah.gnu.org/releases/lwip/lwip-1.4.0.zip
  http://download.savannah.gnu.org/releases/lwip/contrib-1.4.0.zip

  progress: reset flags at transfer start
  
  When an easy handle is used to download an URI which has no
  Content-Length header (or equivalent) after downloading an URI which
  does, the value from the previous transfer is reused and returned by
  CURLINFO_CONTENT_LENGTH_DOWNLOAD. This is because the progress flags
  (used to determine whether such a header was received) are not reset
  between transfers.

  When libcurl has said to the server that there's a POST or PUT coming

  Autobuild submitters can use this to add some text to their

  network issues or dependent libraries, explaining away compiler
  warnings or providing any additional information that could be
  useful to people reviewing and investigating problems with the
  publicly available autobuild logs.  Note that persistent test
  failures that are not issues with curl itself should normally be
  fixed by excluding them from the test run instead.
  
  This is an entirely optional field that is not entered by the
  user the first time a new build is created.

- Fixed compilation when RTSP is disabled

- Fixed LDAP after RTSP readwrite change

Daniel Stenberg (6 May 2011)
- RELEASE-NOTES: synced with 32001ac4149b206

- set_userpass: convert from protocol-specific to generic
  
  The protocol handler's flags field now can set that the protocol
  requires a password, so that the set_userpass function doesn't have to
  have the specific knowledge of which protocols that do.

- RTSP: cleanups
  
  Made several functions static
  
  Made one function defined to nothing when RTSP is disabled to avoid
  the #ifdefs in code.
  
  Removed explicit rtsp.h includes

- RTSP: convert protocol-specific checks to generic
  
  Add a 'readwrite' function to the protocol handler struct and use that
  for the extra readwrite functionality RTSP needs.

- SSL: check for SSL, not specific protocols
  
  Code cleanup to check less for protocols and more for the specific
  relevant feature. Like if SSL is required.

- http_perhapsrewind: remove HTTP check
  
  No need to check for HTTP as this is now a HTTP-specific function

- http_perhapsrewind:
  
  make it static, remove Curl_ prefix

- remove FILE protocol-specific checks
  
  Also, convert the BANPROXY flag into NONETWORK for the protocols
  (file:// only atm) that don't work over networks.

- curl.1: --socks* options no longer needed
  
  As we now can specify all the socks proxy types with the regular --proxy
  option using protocol prefix.

- socks proxy: allow socks5h:// prefix too
  
  Using 'socks5h' as proxy protocol will make it a
  CURLPROXY_SOCKS5_HOSTNAME proxy which is SOCKS5 and asking the proxy to
  resolve host names. I found no "standard" protocol name for this.

- curl.1: minor edit of --ftp-ssl*

- [Jari Aalto brought this change]

  curl.1: use GNU style and sort options
  
  Follow style of GNU layout (cp, mv ...) where options are separated with
  comma: -o, --option
  
  Order item alphabetically (by length also): -o, -O, --option
  
  Follow style of GNU layout by moving help related options to the end:
  --help, -M, --version

- Corrected comments
  
  closepolicy has been deprecated and unused for years

- ConnectionStore: remove unused return code

- indent correctly

- curl_easy_getinfo.3: clarify some timing info

- curl_easy_setopt.3: clarify the SSH KEYFILE options usage
  
  The internal defaults are important info

- docs: mention the protocol:// support in proxy strings

- --data-ascii: add mention
  
  As it is a separate option it should have a .IP title

- url encode docs: mention '-', '.', '_' and '~'
  
  Clarify that the '-', '.', '_' or '~' letters are also not escaped since
  they shouldn't according to RFC3986 section 2.3.
  
  This is how this function has behaved since sep 2010, commit
  5df13c31735fa0.

- SSH: set non-blocking earlier
  
  Introduce an INIT state for the SSH state machine and set libssh2
  non-blocking in that so that it is set properly before
  libssh2_session_startup() is called.
  
  Bug: http://curl.haxx.se/mail/archive-2011-05/0001.html

- curl_formfree.3: mention argument may be NULL
  
  As the code already checks for it we can just as well make it official!

- ConnectionExists: avoid NULL dereference
  
  When checking for connections that are bound to a particular device we
  must make sure we don't compare with a NULL pointer.

- resolver_error: remove bad semicolon

- RELEASE-NOTES: synced with c4bc1d473f324

  function.

- treaded-resolver: better error messages
  
  Now use gai_strerror() to get proper error messages when getaddrinfo()
  has failed. Detect the function in configure.
  
  Code based on work and suggestions by Jeff Pohlmeyer and Guenter Knauf

- proxy: allow socks:// prefix in proxy string
  
  Inspired by a patch from OB.Conseil. Added test case 708 to verify.

- [Zmey Petroff brought this change]

  CMake: improve library search, implement install.
  
  Improved library search by check_function_exists_concat() macro:
  it does not revert the list of libraries any more.
  
  Improved OpenSSL library search: first find zlib, then search for
  openssl libraries that may depend on zlib.
  
  For Unix: openssl libraries can now be detected in nonstandard
  locations. Supply CMAKE_LIBRARY_PATH to CMake on command line.
  
  Added installation capability (very basic one yet).

- multi-socks: fix connect to proxy
  
  When connecting to a socks or similar proxy we do the proxy handshake at
  once when we know the TCP connect is completed and we only consider the
  "connection" complete after the proxy handshake. This fixes test 564
  which is now no longer considered disabled.

  Source files given with absolute paths do not have the
  -D directory specifier prepended.

Daniel Stenberg (27 Apr 2011)
- make: add checksrc.pl to dist

- make: add 'checksrc' as target to check code style
  
  The make target checksrc now works in the root makefile and in both the
  src and lib directories.
  
  It is also run automatically on "all" if configure --enable-debug was
  used.

- checksrc: whitespace and code style cleanup
  
  Make everything adhere to the standards upheld by checksrc.pl and now
  run checksrc from the makefile on debug builds.

- checksrc: add -W to allow a file to be whitelisted
  
  Useful when a known file just doesn't comply and there's no intention to
  make it do so.

- whitespace cleanup: no space first in conditionals
  
  "if(a)" is our style, not "if( a )"

- lib/make: run checksrc.pl once for all files
  
  Since it now supports multiple files this will be faster and will show
  problems for more file than one at a time - more convenient.

- checksrc: scan many files, more checks
  
  It now scans multiple files and outputs an error+warning count summary
  at the end in case at least one was detected.
  
  -D can be used to specify in which dir the files are located
  
  The script now scans for conditions that starts with a space for
  if/while/for lines.

- Makefile: run checksrc if debug enabled
  
  And make the build fail if a warning or error was detected

- checksrc: exit error code if warnings or errors

- SSH: move knownhost logic to separate function

- source cleanup: unify look, style and indent levels
  
  By the use of a the new lib/checksrc.pl script that checks that our
  basic source style rules are followed.

  specified at build time.
  
  The internal resolver API is defined in asyn.h for asynch resolvers.

- asynch resolvers: cleanup

- Improve MinGW static makefile builds.
  
  It is now possible to use any combination of features without

- transfer-encoding: document the options
  
  The new libcurl and command line options are now described.

- transfer-encoding: added new option and cmdline
  
  Added CURLOPT_TRANSFER_ENCODING as the option to set to request Transfer
  Encoding in HTTP requests (if built zlib enabled). I also renamed
  CURLOPT_ENCODING to CURLOPT_ACCEPT_ENCODING (while keeping the old name
  around) to reduce the confusion when we have to encoding options for
  HTTP.
  
  --tr-encoding is now the new command line option for curl to request
  this, and thus I updated the test cases accordingly.

- CURLE_BAD_CONTENT_ENCODING: now used for transfer encoding too

- TE: do the Connection: header
  
  When TE: is inserted in the request, we must add a "Connection: TE" as
  well to be HTTP 1.1 compliant. If a custom Connection: header is passed
  in, we must use that and only append TE to it. Test case 1125 verifies
  TE: + custom Connection:.

- test1124: verify gzip AND chunked transfer-encoding

- TE: rename struct field content_encoding
  
  Since this struct member is used in the code to determine what and how
  to decode automatically and since it is now also used for compressed
  Transfer-Encodings, I renamed it to the more suitable 'auto_decoding'

- HTTP: add support for gzip and deflate Transfer-Encoding
  
  Transfer-Encoding differs from Content-Encoding in a few subtle ways,
  but primarily it concerns the transfer only and not the content so when
  discovered to be compressed we know we have to uncompress it. There will
  only arrive compressed transfers in a response after we have requested
  them with the appropriate TE: header.
  
  Test case 1122 and 1123 verify.

    -w-pia   8060 Possibly incorrect assignment

  * $(MKDIR) and $(RMDIR) have been replaced with the shell-commands 'md'
   and 'rd'. When having MingW/Msys programs 'mkdir.exe' and 'rmdir.exe' in
  $PATH, this confuses Borland's make and the result (the cleaning etc.) would
   not be as expected.
  
  * Removed the preprocessing step; no need for PP_CMD and the .int files.
   curl.exe builds fine w/o and the makefile gets simpler.
  
  * Added a target for creating a compressed hugehelp.c if WITH_ZLIB is  defined.
  It assumes groff, gzip and perl is available if such an "advanced"  users
  requests it. Okay? BTW. My groff and Perl needs unix-slashes ('/').
   Other perls should handle both forms ('/' and '\').

  (Yang?). But I'll leave that for now.

- return code cleanup: build, init and run-time errors
  
  Stop the abuse of CURLE_FAILED_INIT as return code for things not being
  init related by introducing two new return codes:
  
  CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION
  
  CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for
  several years. It is used for returning error when something is
  attempted to be used but the feature/option was not enabled or
  explictitly disabled at build-time. Getting this error mostly means that
  libcurl needs to be rebuilt.
  
  CURLE_FAILED_INIT is now saved and used strictly for init
  failures. Getting this problem means something went seriously wrong,
  like a resource shortage or similar.
  
  CURLE_UNKNOWN_OPTION is the option formerly known as
  CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present,
  separately defined to be removed in a very distant future). This error
  code is meant to be used to return when an option is given to libcurl
  that isn't known. This problem would mostly indicate a problem in the
  program that uses libcurl.

- FTP+proxy: macrofied functions when proxy disabled
  
  In my attempts to reduce #ifdefs in code, the SOCKS functions are now
  macros when libcurl is built without proxy support and therefore the FTP

- http-proxy: move proxy code to http_proxy.c
  
  The new http_proxy.* files now host HTTP proxy specific code (500+ lines
  moved out from http.c), and as a consequence there is a macro introduced
  for the Curl_proxyCONNECT() function so that code can use it without
  actually supporting proxy (or HTTP) in builds.

  A problem not repeatable and no proper recipe given and therefore simply
  removed for now until we hear something else:

- ipv6: only probe once
  
  Move ipv6-functional-probe into a single function that is used from all

  When libcurl sends a HTTP request on a re-used connection and detects it

  connecting to the same server with CURLOPT_SSL_VERIFYPEER equal to one.
  
  This patch turns off the SSL session cache for the particular SSL socket
  if peer verification is disabled.  In order to avoid any performance
  impact, the peer verification is completely skipped in that case, which
  makes it even faster than before.

- ldap: use the new protocol handler setup
  
  Use the new flags field and stop using the old protocol defines.

- TODO-RELEASE: add and remove issues
  
  Removed a fixed issue, added five new existing ones and clarified one of
  the previous ones.

- protocols: use CURLPROTO_ internally
  
  The PROT_* set of internal defines for the protocols is no longer
  used. We now use the same bits internally as we have defined in the
  public header using the CURLPROTO_ prefix. This is for simplicity and
  because the PROT_* prefix was already used duplicated internally for a
  set of KRB4 values.
  
  The PROTOPT_* defines were moved up to just below the struct definition
  within which they are used.

- protocol handler: added flags field
  
  The protocol handler struct got a 'flags' field for special information
  and characteristics of the given protocol.
  
  This now enables us to move away central protocol information such as
  CLOSEACTION and DUALCHANNEL from single defines in a central place, out
  to each protocol's definition. It also made us stop abusing the protocol
  field for other info than the protocol, and we could start cleaning up
  other protocol-specific things by adding flags bits to set in the
  handler struct.
  
  The "protocol" field connectdata struct was removed as well and the code
  now refers directly to the conn->handler->protocol field instead. To
  make things work properly, the code now always store a conn->given
  pointer that points out the original handler struct so that the code can
  learn details from the original protocol even if conn->handler is
  modified along the way - for example when switching to go over a HTTP
  proxy.

  mk-ca-bundle.pl) is now indirectly using this script. I made this small
  tweak to make it easier to automatically maintain the generated
  ca-bundle.crt file in version control.

- SSH: add protocol lock direction
  
  Some protocols have to call the underlying functions without regard to
  what exact state the socket signals. For example even if the socket says
  "readable", the send function might need to be called while uploading,
  or vice versa. This is the case for libssh2 based protocols: SCP and
  SFTP and we now introduce a define to set those protocols and we make
  the multi interface code aware of this concept.
  
  This is another fix to make test 582 run properly.

- state: add missing state to debug table
  
  As a new state recently was added to the IMAP state machine it has to be
  in the array of names as well as otherwise libcurl crashes when a debug
  version runs...

- test 582: enabled again
  
  Commit ca37692bf43b5ef should now hopefully make it run

- ssh_statemach_act: set cselect for sftp upload
  
  For uploads we want to use the _sending_ function even when the socket
  turns out readable as the underlying libssh2 sftp send function will
  deal with both accordingly. This is what the cselect_bits magic is for.
  
  Fixes test 582.

  CURL_CHECK_FUNC_RECVFROM: android/bionic fix

  tests for that as well.

- test582: enabled

- PROT_CLOSEACTION: added SFTP and SCP
  
  Both SFTP and SCP are protocols that need to shut down stuff properly
  when the connection is about to get torned down. The primary effect of
  not doing this shows up as memory leaks (when using SCP or SFTP with the
  multi interface).
  
  This is one of the problems detected by test 582.

- readwrite_upload: stop upload at file size
  
  As we know how much to send, we can and should stop once we've sent that
  much data as it avoids having to rely on other mechanisms to detect the
  end.
  
  This is one of the problems detected by test 582.
  
  Reported by: Henry Ludemann <misc@hl.id.au>

- sftp upload: expire to advance state machine
  
  When using the multi_socket API to do SFTP upload, it is important that
  we set a quick expire when leaving the SSH_SFTP_UPLOAD_INIT state as
  there's nothing happening on the socket so there's no read or write to
  wait for, but the next libssh2 API function needs to be called to get
  the ball rolling.
  
  This is one of the problems detected by test 582.

  multi: close connection on timeout
  
  After a request times out, the connection wasn't properly closed and
  prevented to get re-used, so subsequent transfers could still mistakenly
  get to use the previously aborted connection.

- multi: better failed connect treatment
  
  When failing to connect the protocol during the CURLM_STATE_PROTOCONNECT
  state, Curl_done() has to be called with the premature flag set TRUE as
  for the pingpong protocols this can be important.
  
  When Curl_done() is called with premature == TRUE, it needs to call
  Curl_disconnect() with its 'dead_connection' argument set to TRUE as
  well so that any protocol handler's disconnect function won't attempt to
  use the (control) connection for anything.
  
  This problem caused the pingpong protocols to fail to disconnect when
  STARTTLS failed.

  CURLE_TLSAUTH_FAILED: removed
  
  On second thought, I think CURLE_TLSAUTH_FAILED should be eliminated. It
  was only being raised when an internal error occurred while allocating
  or setting the GnuTLS SRP client credentials struct. For TLS
  authentication failures, the general CURLE_SSL_CONNECT_ERROR seems
  appropriate; its error string already includes "passwords" as a possible
  cause. Having a separate TLS auth error code might also cause people to
  think that a TLS auth failure means the wrong username or password was
  entered, when it could also be a sign of a man-in-the-middle attack.

  CURLE_ABORTED_BY_CALLBACK properly and not CURLE_OK as before to allow the
  callback to properly abort the operation.

  Typo / spelling fixes.

  Also spelling fix for RECIPIENT #define.

- [Brad Hards brought this change]

  Add angle brackets to addresses in easy SMTP examples, as for smtp-multi example.

- cookies: tricked dotcounter fixed
  
  Providing multiple dots in a series in the domain field (domain=..com) could
  trick the cookie engine to wrongly accept the cookie believing it to be
  fine. Since the tailmatching would then match all .com sites, the cookie would
  then be sent to all of them.
  
  The code now requires at least one letter between each dot for them to be
  counted. Edited test case 61 to verify this.

- multi: connect fail => use next IP address
  
  When using the multi interface and connecting to a host name that
  resolves to multiple IP addresses, there was no logic that made it
  continue to the next IP if connecting to the first address times
  out. This is now corrected.

- smtp-multi: put recipient within <brackets>
  
  Even if libcurl might to do it for us, it is more correct.

- ossl_seed: no more RAND_screen
  
  RAND_screen() is slow, not thread-safe and not needed anymore since OpenSSL
  uses the thread-safe win32 CryptoAPI nowadays.

- multi: inhibit some verbose outputs
  
  The info about pipe status and expire cleared are clearly debug-related
  and not anything mere mortals will or should care about so they are now
  ifdef'ed DEBUGBUILD

- SMTP tests: updated MAIL FROM use
  
  They were all wrong previously since none used the <brackets> they
  should for MAIL FROM. Now libcurl adds them itself if the app doesn't so
  they end up wrong less easy.

- CURLOPT_MAIL_FROM: document the bracket situation

- [Brad Hards brought this change]

  SMTP: add brackets for MAIL FROM

  ossl_connect_common() now checks whether or not 'struct

  return CURLE_OK with 'done' set to 'TRUE'. This check prevents
  ossl_connect_common() from creating a new ssl connection on an existing
  ssl session which causes openssl to fail when it tries to parse an
  encrypted TLS packet since the cipher data was effectively thrown away
  when the new ssl connection was created.

- Curl_wait_for_resolv: correct timeout
  
  When looping in this function and checking for the timeout being
  expired, it was not updating the reference time when calculating the
  timediff since previous round which made it think each subsequent loop
  to have taken longer than it actually did.

Daniel Stenberg (11 Nov 2010)
- HTTP Auth: Add CURLAUTH_ONLY
  
  This is a meta symbol. OR this value together with a single specific
  auth value to force libcurl to probe for un-restricted auth and if not,
  only that single auth algorithm is acceptable.
  
  For example you can use CURLAUTH_DIGEST|CURLAUTH_ONLY to make libcurl
  first probe for what method to use, but yet only consider Digest to be
  acceptable.
  
  Using _only_ CURLAUTH_DIGEST without the CURLAUTH_ONLY field, will make
  libcurl explicitly use Digest right away and not do any probing.

- ip_version: moved to connection struct
  
  The IP version choice was previously only in the UserDefined struct
  within the SessionHandle, but since we sometimes alter that option
  during a request we need to have it on a per-connection basis.
  
  I also moved more "init conn" code into the allocate_conn() function
  which is designed for that purpose more or less.

  My copy and paste job was a little too much copy and I missed to adjust

- CURLOPT_RESOLVE: added
  
  CURLOPT_RESOLVE is a new option that sends along a curl_slist with
  name:port:address sets that will populate the DNS cache with entries so
  that request can be "fooled" to use another host than what otherwise
  would've been used. Previously we've encouraged the use of Host: for
  that when dealing with HTTP, but this new feature has the added bonus
  that it allows the name from the URL to be used for TLS SNI and server
  certificate name checks as well.
  
  This is a first change. Surely more will follow to make it decent.

  save metadata to extended file attributes
  
  It is often convinient to track back the source of a once downloaded

  alongside the retrieved file by using the extended attributes (if
  supported by the file system and enabled by --xattr).

- test: remove test 580
  
  Test 580 is removed again for two reasons:
  
  1) Some compilers aren't satisfied by just a data variable called 'test'
  when first.o wants a function called 'test'. The Solaris compiler says
  "ld: warning: symbol `test' has differing types:" while the AIX compiler
  downright rejects it.
  
  2) Test case 1119 that was added after this test is way more complete
  and cover everything test 580 does and more without introducing the same
  problems.

- certcheck: use the custom Host: name for checks
  
  If you use a custom Host: name in a request to a SSL server, libcurl
  will now use that given name when it verifies the server certificate to
  be correct rather than using the host name used in the actual URL.

- SNI: simplify the custom host name use
  
  The redirect check is already done at the position where the customhost
  field is assigned so there's no point in doing that a second time.

- host: get the custom Host: name more genericly
  
  When given a custom host name in a Host: header, we can use it for
  several different purposes other than just cookies, so we rename it and
  use it for SSL SNI etc.

- example: add smtp-multi.c
  
  An example application source code sending SMTP mail with the multi
  interface. It is based on the code Alona Rossen provided, which in turn
  is based on existing example/test code, and I converted it even more

  to edit at the top and I added some comments.

- dist: add symbol-scan.pl to the tarball

- test1119: verify symbols-in-versions

- runtests: allow tests written as perl scripts
  
  If a command is set type="perl", it can now specify a perl program that will
  be run instead of an ordinary curl or built tool.
  
  A perl test automatically disables memory and valgrind debugging.

- symbol-scan: verifies symbols-in-versions
  
  This new script scans for all enums and #defines used by the curl/curl.h
  and curl/multi.h headers. Then it reads all symbols mentioned in
  symbols-in-vesions and make sure that there's no entries missing in
  there. It then proceeds to verify that the entries that
  symbols-in-vesions mentions but aren't found in the sources are truly
  documented as removed.
  
  This script is used in the new test case 1119

- symbols-in-versions: added 119 missing symbols
  
  I've developed a script I call symbol-scan.pl that scans the curl.h and
  multi.h header files and compare the symbols it finds in there with the
  symbols symbols-in-versions documents and outputs a report on the
  differences.  Using this I've dug through the history to fill up
  symbols-in-versions with all the symbols my script found mismatches for.
  
  I will commit symbol-scan.pl separatly and think of a way to put it to
  use in the build/tests so that we from now on will get this in-sync
  check automatically.

Dan Fandrich (2 Nov 2010)
- Added mk580.pl to the tar ball

Daniel Stenberg (2 Nov 2010)
- symbols-in-versions: added missing symbols

- ignore: lib580.c is generated by mk580.pl

- test: added test 580 - verifies symbols-in-versions
  
  The new perl script mk580.pl generates a C table in a fresh source file
  named lib580.c and if that compiles fine we know that the file
  docs/libcurl/symbols-in-versions at least doesn't include any symbols
  that are misspelled.
  
  An additional feature would be to somehow scan curl/curl.h and compare
  with symbols-in-versions to see if there are symbols missing.

- SSH: use libssh2_session_handshake()
  
  In libssh2 1.2.8, libssh2_session_handshake() replaces
  libssh2_session_startup() to fix the previous portability problem with
  the socket type that was too small for win64 and thus easily could cause
  crashes and more.

- SSH: avoid using the libssh2_ prefix
  
  It is a bad idea to use the public prefix used by another library and
  now we realize that libssh2 introduces a symbol in the upcoming version
  1.2.8 that conflicts with our static function named libssh2_free.

- formdata: provide error message
  
  When failing to build form post due to an error, the code now does a
  proper failf(). Previously libcurl would report an error like "failed
  creating formpost data" when a file wasn't possible to open which was
  not easy for users to figure out.
  
  I also lower cased a function name to be named more curl-style and
  removed some unnecessary code.

- URL-parsing: consider ? a divider
  
  The URL parser got a little stricter as it now considers a ? to be a
  host name divider so that the slightly sloppier URLs work too. The
  problem that made me do this change was the reported problem with an URL
  like: www.example.com?email=name@example.com This form of URL is not
  really a legal URL (due to the missing slash after the host name) but is
  widely accepted by all major browsers and libcurl also already accepted
  it, it was just the '@' letter that triggered the problem now.
  
  The side-effect of this change is that now libcurl no longer accepts the
  ?  letter as part of user-name or password when given in the URL, which
  it used to accept (and is tested in test 191). That letter is however
  mentioned in RFC3986 to be required to be percent encoded since it is
  used as a divider.

- SFTP: more ignoring negative file sizes
  
  As the change in 5f0ae7a0626cbe709 added a precaution against negative
  file sizes that for some reason managed to get returned, this change now
  introduces the same check at the second place in the code where the file
  size from the libssh2 stat call is used.
  
  This check might not be suitable for a 32 bit curl_off_t, but libssh2.h
  assumes long long to work and to be 64 bit so I believe such a small
  curl_off_t will be very unlikely to occur in the wild.

  Also made the code break at 80 lines.

- krb5-gssapi: Made the function always return a value.
  
  kr5_auth missed a final 'return' statement. This is not an error in
  gcc but can lead to potential bugs.

- krb5-gssapi: Delete the GSS-API context.
  
  This fixes a memory leak related to the GSS-API code.
  
  Added a krb5_init and krb5_end functions. Also removed a work-around
  the lack of proper initialization of the GSS-API context.

- HTTP: remove special case for 416
  
  It was pointed out that the special case libcurl did for 416 was
  incorrect and wrong. 416 is not really different to other errors so the
  response body must be handled like for other errors/http responses.
  
  Reported by: Chris Smowton
  Bug: http://curl.haxx.se/bug/view.cgi?id=3076808

  sws: Added writedelay HTTP server command
  
  This delays between write operations, hopefully making it easier
  to spot problems where libcurl doesn't flush the socket properly
  before waiting for the next response.

- TODO-RELEASE: no bug in ftp_nextconnect
  
  The issue named "266 - Bug in ftp_nextconnect?" was deemed to not be a
  bug and instead resulted in clarified docs.

- curl_easy_setopt.3: CURLOPT_DIRLISTONLY implies dir list
  
  Make it explicit that setting CURLOPT_DIRLISTONLY to 1 will make libcurl
  to list the directory.

- RELEASE-NOTES: synced up to 588402585bae

- TODO-RELEASE: move new features to next release

- README.ares: we know require c-ares 1.6.0

- SFTP: avoid downloading negative sizes!
  
  It is still not clarified exactly why this happens, but libssh2
  sometimes report a negative file size for the remote SFTP file and that
  deeply confuses libcurl (or crashes it) so this precaution is added to
  avoid badness.

  multi & hiper examples: updates and cleanups
  
  all multi and hiper examples:
  
  * don't loop curl_multi_perform calls, that was <7.20.0 style, currently
    the exported multi functions will not return CURLM_CALL_MULTI_PERFORM
  
  all hiper examples:
  * renamed check_run_count to check_multi_info
  * don't  compare current running handle count with previous value, this
    was the wrong way to check for finished requests, simply call
    curl_multi_info_read
  * it's also safe to call curl_multi_remove_handle inside the
    curl_multi_info_read loop.
  
  ghiper.c:
  * replaced curl_multi_socket (that function is marked as obsolete) calls
    with curl_multi_socket_action calls (as in hiperfifo.c and
    evhiperfifo.c)
  
  ghiper.c and evhiperfifo.c:
  * be smart as hiperfifo.c, don't do uncessary curl_multi_* calls in
    new_conn and main

- TODO-RELEASE: one fixed, one postponed, one added
  
  As we're already in feature freeze, I pushed the feature onwards.

- Renamed test1204 to test1117 to move it into the normal range

- Add gopher protocol definition to ILE/RPG binding.
  OS400 compile script in test dir updated for chkhostname.

- krb5-gssapi: Remove several memory leaks.
  
  Remove a leak seen on Kerberos/MIT (gss_OID is copied internally and
  we were leaking it). Now we just pass NULL as advised in RFC2744.
  
  |tmp| was never set back to buf->data.
  
  Cleaned up Curl_sec_end to take into account failure in Curl_sec_login
  (where conn->mech would be NULL but not conn->app_data or
  conn->in_buffer->data).

- security.c: Remove Curl_sec_fflush_fd.
  
  The current implementation would make us send wrong data on a closed
  socket. We don't buffer our data so the method can be safely removed.

- security.c: We should always register the socket handler.
  
  Following a change in the way socket handler are registered, the custom
  recv and send method were conditionaly registered.
  We need to register them everytime to handle the ftp security
  extensions.
  
  Re-added the clear text handling in sec_recv.

- security.c: Fix Curl_sec_login after rewrite.
  
  Curl_sec_login was returning the opposite result that the code in ftp.c
  was expecting. Simplified the return code (using a CURLcode) so to see
  more clearly what is going on.

- security.c: Readd the '\n' to the infof() calls.
  
  They are not automatically added and make the output of the verbose
  mode a lot more readable.

- security.c: Fix typo (PSBZ -> PBSZ)

- security.c: Fix ftp_send_command.
  
  My use of va_args was completely wrong. Fixed the usage so that
  we send the right commands!

- curl_easy_escape: don't escape "unreserved" characters
  
  According to RFC3986 section 2.3 the letters -, ., _ and ~ should not be
  percent-encoded.
  
  Reported by: Miguel Diaz
  Bug: http://curl.haxx.se/mail/lib-2010-09/0227.html

- multi: don't expire timeouts at disonnect or done
  
  The functions Curl_disconnect() and Curl_done() are both used within the
  scope of a single request so they cannot be allowed to use
  Curl_expire(... 0) to kill all timeouts as there are some timeouts that
  are set before a request that are supposed to remain until the request
  is done.
  
  The timeouts are now instead cleared at curl_easy_cleanup() and when the
  multi state machine changes a handle to the complete state.

- Changed the TPF make file to get source files from Makefile.inc
  
  Patch was fixed and validated by David McCreedy.

- Added test case 1204 to test HTTP range failure
  
  This is an attempt to reproduce bug #3076808

  multi_runsingle: set timeout error messages
  
  With the latest changes to fix the timeout handling with multi interface
  we lost the timeout error messages. This patch brings them back.

- TODO-RELEASE: updated list of issues to work on

- parsedate: allow time specified without seconds
  
  The date format in RFC822 allows that the seconds part of HH:MM:SS is
  left out, but this function didn't allow it. This change also includes a
  modified test case that makes sure that this now works.

  TFTP: Work around tftpd-hpa upload bug
  
  tftpd-hpa has a bug where it will send an incorrect ack when the block
  counter wraps and tftp options have been sent. Work around that by
  accepting an ack for 65535 when we're expecting one for 0.

- Revert "security.c: buffer_read various fixes."
  
  This reverts commit fbb38de415b7bb7d743e53a7b4b887ffb12b3e5b.

- security.c: removed superfluous parentheses
  
  And also removed the FIXME where memory was zeroed just before freed,
  and some other minor whitespace changes.

  security.c: Update the #include statements after the rewrite.
