Version 7.24.0 (24 Jan 2012)

Version 7.24.0 (24 Jan 2012)
  

Version 7.24.0 (24 Jan 2012)
  Synced and prepared for 7.24.0 release. Two security problems, one bug fix,

Version 7.24.0 (24 Jan 2012)
  two more contributors.

- gnutls: enforced use of SSLv3
  
  With advice from Nikos Mavrogiannopoulos, changed the priority string to
  add "actual priorities" and favour ARCFOUR. This makes libcurl work
  better when enforcing SSLv3 with GnuTLS. Both in the sense that the
  libmicrohttpd test is now working again but also that it mitigates a
  weakness in the older SSL/TLS protocols.
  
  Bug: http://curl.haxx.se/mail/lib-2012-01/0225.html
  Reported by: Christian Grothoff

- tests: test CRLF in URLs
  
  Related to the security vulnerability: CVE-2012-0036
  
  Bug: http://curl.haxx.se/docs/adv_20120124.html

- URL sanitize: reject URLs containing bad data
  
  Protocols (IMAP, POP3 and SMTP) that use the path part of a URL in a
  decoded manner now use the new Curl_urldecode() function to reject URLs
  with embedded control codes (anything that is or decodes to a byte value
  less than 32).
  
  URLs containing such codes could easily otherwise be used to do harm and
  allow users to do unintended actions with otherwise innocent tools and
  applications. Like for example using a URL like
  pop3://pop3.example.com/1%0d%0aDELE%201 when the app wants a URL to get
  a mail and instead this would delete one.
  
  This flaw is considered a security vulnerability: CVE-2012-0036
  
  Security advisory at: http://curl.haxx.se/docs/adv_20120124.html
  
  Reported by: Dan Fandrich

- OpenSSL: don't disable security work-around
  
  OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability
  (http://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit
  to SSL_OP_ALL that _disables_ that work-around despite the fact that
  SSL_OP_ALL is documented to do "rather harmless" workarounds.
  
  The libcurl code uses the SSL_OP_ALL define and thus logically always
  disables the OpenSSL fix.
  
  In order to keep the secure work-around workding, the
  SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit must not be set and this change
  makes sure of this.

  Leak triggered when CURLOPT_SSLCERTTYPE and CURLOPT_SSLKEYTYPE set to P12
  and both CURLOPT_SSLCERT and CURLOPT_SSLKEY point to the same PKCS#12 file.

- OpenSSL: SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option is no longer enabled
  
  SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option enabling allowed successfull
  interoperability with web server Netscape Enterprise Server 2.0.1 released
  back in 1996 more than 15 years ago.
  
  Due to CVE-2010-4180, option SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG has
  become ineffective as of OpenSSL 0.9.8q and 1.0.0c. In order to mitigate
  CVE-2010-4180 when using previous OpenSSL versions we no longer enable
  this option regardless of OpenSSL version and SSL_OP_ALL definition.

- tests: enable time tracing on tests 500, 573 and 585

- curl.h: provide backwards compatible symbols
  
  In commit c834213ad52 we re-used some obsolete error codes, and here are
  two defines that makes sure existing source codes that happen to use any
  of these deprecated ones will still compile.
  
  As usual, define CURL_NO_OLDIES to avoid getting these "precaution
  defines".

- win32-threaded-resolver: stop using a dummy socket
  
  Previously the code would create a dummy socket while resolving just to
  have curl_multi_fdset() return something but the non-win32 version
  doesn't do it this way and the creation and use of a socket that isn't
  made with the common create-socket callback can be confusing to apps
  using the multi_socket API etc.
  
  This change removes the dummy socket and thus will cause
  curl_multi_fdset() to return with maxfd == -1 more often.

  Fixed a problem in POP3 and IMAP where a connection would fail when
  CURLUSESSL_TRY was specified for a server that didn't support
  SSL/TLS connections rather than continuing.

- [Steve Holme brought this change]

  Fixed incorrect error code being returned in STARTTLS
  
  The STARTTLS response code in SMTP, POP3 and IMAP would return
  CURLE_LOGIN_DENIED rather than CURLE_USE_SSL_FAILED when SSL/TLS
  was not available on the server.

- create_hostcache_id: use the key lower cased
  
  ... to make sure the DNS cache is properly case insensitive

- changed case: use new host name for subsequent HTTP requests
  
  When a HTTP connection is re-used for a subsequent request without
  proxy, it would always re-use the Host: header of the first request. As
  host names are case insensitive it would make curl send another host
  name case that what the particular request used.
  
  Now it will instead always use the most recent host name to always use
  the desired casing.
  
  Added test case 1318 to verify.

- CURLOPT_RESOLVE: avoid adding already present host names
  
  The load host names to DNS cache function was moved to hostip.c and it
  now makes sure to not add host names that already are present in the

  the --resolve and multiple URLs on the command line.

- TODO: remove active FTP from section 2.1
  
  It is no longer done blocking in the multi interface

- libcurl docs: add the new FTP accept option + errors

- timeleft_accept: ack global timeout, moved to ftp.c
  
  First off the timeout for accepting a server connect back must of course
  respect a global timeout. Then the timeleft function is only used by ftp
  code so it was moved to ftp.c and made static.

- libcurl-tutorial.3: curl doesn't sent pragma no-cache
  
  It did a long time ago

- libcurl-multi.3: active FTP is no longer blocking!

- FTP: move FTP-specific struct field to ftpc_conn
  
  "wait_data_conn" was added to the connectionbits in commit c834213ad5 for
  handling active FTP connections but as it is purely FTP specific and now
  only ever accessed by ftp.c I moved it into the FTP connection struct.

- non-blocking active FTP: cleanup multi state usage
  
  Backpedaled out the funny double-change of state in the multi state
  machine by adding a new argument to the do_more() function to signal
  completion. This way it can remain in the DO_MORE state properly until
  done. Long term, the entire DO_MORE logic should be moved into the FTP
  code and be hidden from the multi code as the logic is only used for
  FTP.

- [Gokhan Sengun brought this change]

  FTP: perform active connections non-blocking
  
  1- Two new error codes are introduced.
  
  CURLE_FTP_ACCEPT_FAILED to be set whenever ACCEPTing fails because of
  FTP server connected.
  
  CURLE_FTP_ACCEPT_TIMEOUT to be set whenever ACCEPTing timeouts.
  
  Neither of these errors are considered fatal and control connection
  remains OK because it could just be a firewall blocking server to
  connect to the client.
  
  2- One new setopt option was introduced.
  
  CURLOPT_ACCEPTTIMEOUT_MS
  
  It sets the maximum amount of time FTP client is going to wait for a
  server to connect. Internal default accept timeout is 60 seconds.

- sockets: new Curl_socket_check() can wait for 3 sockets
  
  This offers an alternative to the existing Curl_socket_ready() API which
  only checks one socket for read and one for write.

  curl.h: add __ANDROID__ macro check
  
  When working with the Android Standalone Toolchain the compiler defines
  this macro:
  
    /path/to/arm-linux-androideabi-gcc -E -dM - < /dev/null \
    | grep -i android
    #define __ANDROID__ 1
  
  We really need to check both ANDROID and __ANDROID__ since I've observed
  that:
  
  * if you use Android.mk file(s) and the 'ndk-build' script (aka vanilla
  way), ANDROID is predefined (see -DANDROID extra C flag),
  
  * if you use the Android Standalone Toolchain, then __ANDROID__ is
  predefined as stated by the compiler

- lib500: verify timers relative each other
  
  As commit ce896875f8 fixed a timer that accidentally had been moved in
  code and then returned a bad timer, the lib500.c code (used in test 500
  and some others) now verifies 5 timers against each other to verify that
  they have the correct relative values. We cannot compare against
  absolute values as the timings will vary a lot.

- Curl_pgrsTime: store now in an auto variable
  
  It makes it easier to introduce debug outputs in this function, and
  everything in the function is using the value anyway so it might even be
  more efficient.

- timer: restore PRETRANSFER timing
  
  Regression introduced in 7.23.0 with commit 9dd85bce. The function in
  which the PRETRANSFER time stamp was recorded was moved in time causing
  it be stored very quickly after the start timestamp. On most systems
  shorter than 1 millisecond and thus it wouldn't even show with -w
  "%{time_pretransfer}" using the command line tool.

  CURLOPT_INTERFACE: avoid resolving interfaces names
  
  Do not try to resolve interfaces names via DNS by recognizing interface
  names in a few ways.  If the interface option argument has a prefix of
  "if!" then treat the argument as only an interface.  Similarly, if the
  interface argument is the name of an interface (even if it does not have
  an IP address assigned), treat it as an interface name.  Finally, if the
  interface argument is prefixed by "host!" treat it as a hostname that
  must be resolved by /etc/hosts or DNS.
  
  These changes allow a client using the multi interfaces to avoid
  blocking on name resolution if the interface loses its IP address or
  disappears.

  multi: handle timeouts on DNS servers by checking for new sockets
  
  If the first name server is not available, the multi interface does

  calling Curl_resolver_is_resolved.
  
  This bug can be reproduced if Curl is complied with --enable_ares and
  your code uses the multi socket interfaces and the
  CURLMOPT_SOCKETFUNCTION option.  To test try:

- POP3: detect when LIST returns no mails
  
  By making sure the function can detect an "end of body" sequence
  immediately on the first line, test 811 is now enabled.

- ftpserver: output CRLF in logs
  
  Previously the log function would just filter out all CR and LF
  occurances from the log to make it more readable. This had the downside
  that it made it very hard to see CR LFs when they actually matters.
  
  Now, they're instead converted to "[CR]" and "[LR]" in the log to become
  apparent to readers.

- POP3: fix end of body detection
  
  Curl_pop3_write() now has a state machine that scans for the end of a
  POP3 body so that the CR LF '.' CR LF sequence can come in everything
  from one up to five subsequent packets.
  
  Test case 810 is modified to use SLOWDOWN which makes the server pause
  between each single byte and thus makes the POP3 body get sent to curl
  basically one byte at a time.

  HTTP auth: fix proxy Negotiate bug
  
  If a proxy offers several Authentication schemes where NTLM and
  Negotiate are offered by the proxy and you tell libcurl not to use the
  Negotiate scheme then the request never returns when the proxy answers
  with its HTTP 407 reply.
  
  It is reproducible by the following steps:
  
  - Use a proxy that offers NTLM and Negotiate ( CURLOPT_PROXY and
  CURLOPT_PROXYPORT )
  
  - Tell libcurl NOT to use Negotiate CURL_EASY_SETOPT(CURLOPT_PROXYAUTH,
  CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_NTLM )
  
  - Start the request
  
  The call to CURL_EASY_PERFORM never returns. If you switch on debug
  logging you can see that libcurl issues a new request As soon as it
  received the 407 reply. Instead it should return and set the response
  code to 407.

- large headers: have curl accept >16K headers
  
  As commit 5850cc4808ab clarifies, libcurl can deliver header lines that
  are longer than CURL_MAX_WRITE_SIZE, only body data is limited to that
  size. The curl tool has check (when built debug-enabled) that made the
  wrong checks and this new test 1205 verifies that larger headers work.

- curl_multi_fdset: correct fdset with FTP PORT use
  
  After a PORT has been issued, and the multi handle would switch to the
  CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would
  return the wrong fdset to wait for when curl_multi_fdset() is
  called. The code would blindly assume that it was waiting for a connect
  of the second connection, while that isn't true immediately after the
  PORT command.
  
  Also, the function multi.c:domore_getsock() was highly FTP-centric and
  therefore ugly to keep in protocol-agnostic code. I solved this problem
  by introducing a new function pointer in the Curl_handler struct called
  domore_getsock() which is only called during the DOMORE state for
  protocols that set that pointer.
  
  The new ftp.c:ftp_domore_getsock() function now returns fdset info about
  the control connection's command/response handling while such a state is
  in use, and goes over to waiting for a writable second connection first
  once the commands are done.
  
  The original problem could be seen by running test 525 and checking the
  time stamps in the FTP server log. I can verify that this fix at least
  fixes this problem.

  smtp: Added support for NTLM authentication
  
  Modified smtp_endofresp() to detect NTLM from the server specified list
  of supported authentication mechanisms.
  
  Modified smtp_authenticate() to start the sending of the NTLM data.
  
  Added smtp_auth_ntlm_type1_message() which creates a NTLM type-1
  message. This function is used by authenticate() to start the sending
  of data and by smtp_state_auth_ntlm_resp() when the AUTH command
  doesn't contain the type-1 message as part of the initial response.
  This lack of initial response can happen if an OOM error occurs or the
  type-1 message is longer than 504 characters. As the main AUTH command
  is limited to 512 character the data has to be transmitted in two
  parts; one containing the AUTH NTLM and the second containing the
  type-1 message.
  
  Added smtp_state_auth_ntlm_type2msg_resp() which handles the incoming
  type-2 message and sends an outgoing type-3 message. This type-2
  message is sent by the server in response to our type-1 message.
  
  Modified smtp_state_auth_resp() to handle the response to: the AUTH
  NTLM without the initial response and the type-2 response.
  
  Modified smtp_disconnect() to cleanup the NTLM SSPI stack.

- POST: always set postfieldsize
  
  When we use binary posts and regular ones intermixed on a single command

  (when inserting '&' and more). We must therefore keep track of the post
  data length. Then we also end up setting the libcurl option with the
  known size, so that we don't risk that libcurl will do strlen() on the
  data.
  
  This has the minor side-effect that --libcurl source codes now always
  will use CURLOPT_POSTFIELDSIZE but I don't consider that terribly
  damaging.

  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.

- 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.

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.

  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.

- 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.

- 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.

- 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.

- 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.

- 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 ;-)

- 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

  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.

  The list of test cases in Makefile.am is now sorted numerically.

- include: cleanup

- 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.

  * $(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.

Daniel Stenberg (5 Apr 2011)
- 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.

- disable cookies: remove ifdefs, move code
  
  1 - make sure to #define macros for cookie functions in the cookie
  header when cookies are disabled to avoid having to use #ifdefs in code
  using those functions.
  
  2 - move cookie-specific code to cookie.c and use the functio
  conditionally as mentioned in (1).
  
  net result: 6 #if lines removed, and 9 lines of code less

- multi: shorten lines

- multi: conn goes bad when data change
  
  Within multi_socket when conn is used as a shorthand, data could be
  changed and multi_runsingle could modify the connectdata struct to deal
  with. This bug has not been included in a public release.
  
  Using 'conn' like that turned out to be ugly. This change is a partial
  revert of commit f1c6cd42f474df59.

- curl_easy_setopt.3: mention TFTP read callback flaw
  
  The read callback must return the exact requested amount of data when it
  is used for doing TFTP uploads. This is due to how it deals with data
  internally. This could/should be fixed but for now we document the
  existing behavior.

- RELEASE-NOTES: synced with 11c2db2aa2a

- fix: re-use of bound connections
  
  When asked to bind the local end of a connection when doing a request,
  the code will now disqualify other existing connections from re-use even
  if they are connected to the correct remote host.
  
  This will also affect which connections that can be used for pipelining,
  so that only connections that aren't bound or bound to the same
  device/port you're asking for will be considered.

- symbols-in-versions: make test 1119 happy

- rtsp: move protocol code to dedicated file
  
  The RTSP-specific function for checking for "dead" connection is better
  located in rtsp.c. The code using this is now written without #ifdefs as
  the function call is instead turned into a macro (in rtsp.h) when RTSP
  is disabled.

  Added a little generic info section about the lists and a section about
  how to deal with trolls and spam on the lists.

- TODO-RELEASE: 1 fixed, 1 notabug
  
  Fixed:
  
  271 - fix the IPv6-working probing to only exist at one place in the code and
        only get done once
  
  A problem not repeatable and no proper recipe given and therefore simply
  removed for now until we hear something else:
  
  282 - 100 Continue responses should return the "final" HTTP response code:
        "Getting the HTTP response code following a 100 Continue"

- ipv6: only probe once
  
  Move ipv6-functional-probe into a single function that is used from all
  places that need to know.
  
  Make the probe function store the result in a static variable so that
  subsequent invokes just returns the previous result and won't have to
  probe again.

- headers: more copyright headers added

- MAIL-ETIQUETTE: how to behave
  
  This is a new documentation for the source tree. This information has
  been present since a long time at
  http://curl.haxx.se/mail/etiquette.html but now it is put into a plain

- retry-request: rewind if data was sent
  
  When libcurl sends a HTTP request on a re-used connection and detects it
  being closed (ie no data at all was read from it), it is important to
  rewind if any data in the request was sent using the read callback or
  was read from file, as otherwise the retried request will be broken.

- nss: do not ignore value of CURLOPT_SSL_VERIFYPEER
  
  When NSS-powered libcurl connected to a SSL server with
  CURLOPT_SSL_VERIFYPEER equal to zero, NSS remembered that the peer
  certificate was accepted by libcurl and did not ask the second time when
  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: Only download if modified
  
  Only download and convert the certdata to the ca-bundle.crt if Mozilla
  changed the data
  
  The Perl LWP module (which in a bit of a circular reference is used by
  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
  
  recvfrom in bionic (the android libc) deviates from POSIX and uses a
  const in the 5th argument ("const struct sockaddr *") so the check now
  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.
