- progress_cb: avoid buffer overflow

  The progress bar output function would blindly use the terminal width
  without bounds checking. When using a very wide terminal that caused a
  buffer overflow and segfault.

  We now limit the max bar with to 255 columns, and I simplified the code
  to avoid an extra snprintf and buffer.

- ftp PORT: don't hang if bind() fails

  When the user requests PORT with a specific port or port range, the code
  could lock up in an endless loop. There's now an extra conditional that
  makes sure to special treat the error and try the local address only
  once so a second failure will abort the loop correctly.

- pingpong: change two comments wrongly referring "FTP"

  Just a sign of where the code originally was ripped out from. Now it is
  generic "pingpong".

- test 590: verify the bug fix in 4851dafcf1

  This test is created to verify Rene Bernhardt's patch which makes sure
  libcurl properly _not_ deals with Negotiate if not asked to even if the
  proxy says it can serve it.

- [Rene Bernhardt brought this change]

  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.

- ssluse.c: fix calling of OpenSSL's ERR_remove_state(0)

  Move calling of ERR_remove_state(0) a.k.a ERR_remove_thread_state(NULL)
  from Curl_ossl_close_all() to Curl_ossl_cleanup().

  In this way ERR_remove_state(0) is now only called in libcurl by
  curl_global_cleanup(). Previously it would get called by functions
  curl_easy_cleanup(), curl_multi_cleanup and potentially each time a
  connection was removed from a connection cache leading to premature
  destruction of OpenSSL's thread local state hash.

  Multi-threaded apps using OpenSSL enabled libcurl should still call
  function ERR_remove_state(0) or ERR_remove_thread_state(NULL) at the
  very end end of threads that do not call curl_global_cleanup().

- rename ftp_ssl: the struct field is used for many protocols

  Now called 'use_ssl' instead, which better matches the current CURLOPT
  name and since the option is used for all pingpong protocols (at least)
  it makes sense to not use 'ftp' in the name.

  default certificate type anyway.

- FTP test server: fix server unresponsiveness

- ftpserver.pl: three new custom FTP server commands to disable data channel

  NODATACONN421: applies only to active FTP mode, instructs server to not
  establish data connection back to client and reply with FTP 421.

  NODATACONN425: applies only to active FTP mode, instructs server to not
  establish data connection back to client and reply with FTP 425.

  NODATACONN: applies to both active and passive FTP modes, instructs server
  to not establish nor accept a data channel and fool client into believing
  that the data channel connection is possible.

  Some polishing probably required.

- multi.c: OOM handling fix

Daniel Stenberg (27 Oct 2011)
- multi: start ftp state machine when switching to DO_MORE

  This extends the fix from commit d7934b8bd491

  When the multi state is changed within the multi_runsingle from DOING to
  DO_MORE, we didn't immediately start the FTP state machine again. That
  then left the FTP state in FTP_STOP. When curl_multi_fdset() was
  subsequently called, the ftp_domore_getsock() function would return the
  wrong fd info.

  I created test 587 in commit 840eff44f2b but forgot to add the file to

- test 588: verify active FTP with multi interface without EPRT

  This is using the verbatim 525 test code but it disables EPRT in the
  server and this should work just as well anyway.

- FTP server: allow EPRT by default

  EPRT is now supported by default by the server. To disable it, use the
  generic REPLY instruction in the <servercmd> tag. Test 116 now has it
  disabled. All other existing active FTP port tests strip out the port
  commands from the logs already so the change of the server isn't that
  noticable.

- 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.

Daniel Stenberg (21 Oct 2011)
- 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.

  gtls: only call gnutls_transport_set_lowat with <gnutls-2.12.0

  The default lowat level for gnutls-2.12* is set to zero to avoid
  unnecessary system calls and the gnutls_transport_set_lowat function has
  been totally removed in >=gnutls-3 which causes build failures.

  Therefore, the function shouldn't be used except for versions that

- sws.c: HTTP and GOPHER test server-side connection closing adjustment

  When, for a given test, server is instructed to close connection after

  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.

  smtp: General tidy up ready for adding NTLM support

  Changed the name of variable l, in several functions, which represents

  Reworked smtp_authenticate() to be simpler and easier to follow.
  Variables and now initialised in their definitions and if no username
  and password are specified the function sets the state to SMTP_STOP and
  returns immediately, rather than being part of a huge if statement.

  configure - m4: make CURL_CHECK_DEF ignore leading whitespace on symbol def

  When using Sun C compiler the preprocessor somehow inserts an extra space
  in front of replaced symbol, breaking CURL_CHECK_DEF macro. To workaround
  this, macro CURL_CHECK_DEF now ignores all leading whitespace in front of
  symbol substitution result.

  smtp_connect: use defined buffer length for hostname

- [Steve Holme brought this change]

  Curl_ntlm_create_type3_message: Tidied up the use of Curl_gethostname.

  Removed the code that striped off the domain name when Curl_gethostname
  returned the fully qualified domain name as the function has been
  updated to return the un-qualified host name.

  Replaced the use of HOSTNAME_MAX as the size of the buffer in the call
  to Curl_gethostname with sizeof(host) as this is safer should the buffer
  size ever be changed.

- [Steve Holme brought this change]

  HOSTNAME_MAX: Moved to curl_gethostname.h

  Moved HOSTNAME_MAX #define into curl_gethostname.h rather than being
  locally defined in curl_gethostname.c, curl_ntlm_msgs.c and smtp.c.

- POST: always set postfieldsize

  When we use binary posts and regular ones intermixed on a single command
  line, we cannot do strlen() etc on the data to figure out the length
  (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.

- Fix NTLM winbind support to pass the torture tests

  Calling sclose() both in the child and the parent fools the

- 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.

  Ensure existing logic in Curl_resolv_timeout() is not subverted upon getting a

  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.

  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.

- telnet: allow programatic use on Windows

  Summary of the issue can be found at:
  http://curl.haxx.se/mail/lib-2010-04/0367.html

  That patch only updated the unix sockets code - the winsock code was not
  updated and no longer works the same was as the unix code. This change
  updates the windows code accordingly.

- Curl_output_ntlm: remove unused variable

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.

- 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.

- curl_formget: treat CURLFORM_STREAM better

  If a piece is set to use a callback to get the data, it should not be
  treated as data. It unfortunately also requires that curl_easy_perform()
  or similar has been used as otherwise the callback function hasn't been
  figured out and curl_formget won't know how to get the content.

- curl_formget.3: CURLFORM_STREAM has its drawbacks

  Due to a design flaw, the CURLFORM_STREAM option doesn't really work
  with curl_formget until after curl_easy_perform (or similar).

- FAQ: binding clarification

  We don't author the bindings, they are created outside the main project.

  When a time condition isn't met, so that no body is delivered to the

  completely tricked.

- 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

- 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.

  The make target checksrc now works in the root makefile and in both the

  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.

- 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.

  at the end of a session.  This forces NSS to ask for a new client
  certificate when connecting second time to the same host.

  src/Makefile.b32: updates

  * Rename the object object directory from 'objs' to 'BCC_obj' to be in
   sync with my previous patch for lib/Makefile.b32.

  * Turn off these warnings to keep the build totally silent (with CBuilder-6
   that is).
    -w-inl    8026 Functions X are not expanded inline.
    -w-pia   8060 Possibly incorrect assignment
    -w-pin  8061 Initialization is only partially bracketed
   (same added in src/Makefile.b32)

  * $(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 '\').

  lib/Makefile.b32: updates

  * Rename the object object directory from 'objs' to 'BCC_obj'. I feel

  * Turn off these warnings to keep the build totally silent (with CBuilder-6

    -w-inl    8026 Functions X are not expanded inline.

  I'm sure the warnings could be fixed the "proper" way or with some added
  "#pragma" statements. But that just clutters the sources IMHO.

  * $(MKDIR) and $(RMDIR) have been replaced with the shell-commands 'md'

  * Added a ".path.int = $(OBJDIR)" to tell make where the $(PREPROCESSED)
   files are. Why we need the preprocess step in the fist place is beyond me
  (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

  actually supporting proxy (or HTTP) in builds.

  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.

  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

- ssh_statemach_act: set cselect for sftp upload

  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.

- test582: enabled

  multi interface).

  This is one of the problems detected by test 582.

- readwrite_upload: stop upload at file size

- sftp upload: expire to advance state machine

  When using the multi_socket API to do SFTP upload, it is important that

  wait for, but the next libssh2 API function needs to be called to get

  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.

  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.
