- RELEASE-NOTES: synced with 92cf6141ed0de

- curl: fix --oauth2-bearer in the --help output
  
  After the option rename in 5df04bfafd1

- OpenSSL: improve the grammar of the language in 39beaa5ffbcc

  Write to CURLOPT_ERRORBUFFER information about mismatch alternative
  certificate subject names.
  
  Signed-off-by: Andrej E Baranov <admin@andrej-andb.ru>

- curl: rename --bearer to --oauth2-bearer
  
  The option '--bearer' might be slightly ambiguous in name. It doesn't
  create any conflict that I am aware of at the moment, however, OAUTH v2
  is not the only authentication mechanism which uses "bearer" tokens.

- tests: Fixed typos from commit 25a0c96a494297

- tests: Updated email addresses in SMTP tests following recent changes

- test909: Removed custom EHLO response after recent changes
  
  ...as it is no longer required following capability and authentication
  changes and is now causing problems following commit 49341628b50007 as
  the test number is obtained from the client address in the EHLO.

- ftpserver.pl: Fixed compilation error from commit 49341628b50007

- ftpserver.pl: Moved specifying the test number from the RCPT address
  
  ...to the client address as this frees the RCPT strings to contain
  just an email address and by passing the test number into curl as the
  client address remains consistent with POP3 and IMAP tests as they are
  specified in the URL.

- ftpserver.pl: Added unwanted argument check to SMTP DATA command handler

Daniel Stenberg (29 Sep 2013)
- getinmemory: remove a comment
  
  The comment mentioned the need to free the data, but the example already
  does that free

- postinmemory: new example
  
  This is similar to getinmemory.c but with an initial POST.

- win32: fix Visual Studio 2010 build with WINVER >= 0x600
  
  If no WINVER and/or _WIN32_IWNNT define was set, the Windows platform
  SDK often defaults to high value, e.g. 0x601 (whoch may probably depend
  on the Windows version being used, in my case Windows 7).
  
  If WINVER >= 0x600 then winsock2.h includes some defines for WSAPoll(),
  e.g. POLLIN, POLLPRI, POLLOUT etc. These defines clash with cURL's
  lib/select.h.
  
  Make sure HAVE_STRUCT_POLLFD is defined then.

- imap: Added clarification to the code about odd continuation responses

- ftp.c: Fixed compilation warning
  
  There is an implicit conversion from "unsigned long" to "long"

- sasl: Centralised the authentication mechanism strings
  
  Moved the standard SASL mechanism strings into curl_sasl.h rather than
  hard coding the same values over and over again in the protocols that
  use SASL authentication.

  test1112: Increase the timeout from 7s to 16s
  
  As someone reported on the mailing list a while back, the hard-coded
  arbitrary timeout of 7s in test 1112 is not sufficient in some build
  environments. At Arista Networks we build and test curl as part of our
  automated build system, and we've run into this timeout 170 times so
  far. Our build servers are typically quite busy building and testing a
  lot of code in parallel, so despite being beefy machines with 32 cores
  and 128GB of RAM we still hit this 7s timeout regularly.

Steve Holme (22 Sep 2013)
- tests: Fixed smtp rcpt to addresses

- ftpserver.pl: Expanded the SMTP RCPT handler to validate TO addresses
  
  RCPT_smtp() will now check for a correctly formatted TO address which
  allows for invalid recipient addresses to be added.

- ftpserver.pl: Added cURL SMTP server detection to HELO command handler
  
  As curl will send a HELO command after an negative EHLO response, added
  the same detection from commit b07709f7417c3e to the HELO handler to
  ensure the test server is identified correctly and an upload isn't
  performed.

- ftpserver.pl: Corrected response code for successful RCPT command

- ftpserver.pl: Moved invalid RCPT TO: address detection to RCPT handler
  
  Rather than detecting the TO address as missing in the DATA handler,
  moved the detection to the RCPT command handler where an error response
  can be generated.

- RELEASE-NOTES: Corrected missed addition
  
  Somehow commit 60a20461629fda missed the last item in the sync list
  even though I'm sure I added it during editing.

- RELEASE-NOTES: Synced with 6dd8bd8d2f9729

- curl.1: Added information about optional login options to --user in manpage
  
  Added missing information, from curl 7.31.0, regarding the use of the
  optional login options that may be specified as part of --user.
  
  For example:
  
  --user 'user:password;auth=NTLM' in IMAP, POP3 and SMTP protocols.

- ftpserver.pl: Moved cURL SMTP server detection into EHLO command handler
  
  Moved the special SMTP server detection code from the DATA command
  handler, which happens further down the operation chain after EHLO,
  MAIL and RCPT commands, to the EHLO command as it is the first command
  to be generated by a SMTP operation as well as containing the special
  "verifiedserver" string from the URL.
  
  This not only makes it easier and quicker to detect but also means that
  cURL doesn't need to specify "verifiedserver" as --mail-from and
  --mail-rcpt arguments.
  
  More importantly, this also makes the upcoming verification changes to
  the RCPT handler easier to implement.

Daniel Stenberg (21 Sep 2013)
- openssl: use correct port number in error message
  
  In ossl_connect_step2() when the "Unknown SSL protocol error" occurs, it
  would output the local port number instead of the remote one which
  showed when doing SSL over a proxy (but with the correct remote host
  name). As libcurl only speaks SSL to the remote we know it is the remote
  port.
  
  Bug: http://curl.haxx.se/bug/view.cgi?id=1281
  Reported-by: Gordon Marler

- test1415: adjusted to work for 32bit time_t
  
  The libcurl date parser returns INT_MAX for all dates > 2037 so this
  test is now made to use 2037 instead of 2038 to work the same for both
  32bit and 64bit time_t systems.

Steve Holme (21 Sep 2013)
- tests: Reworked existing SMTP tests to be single recipient based
  
  ...in preparation of upcoming multiple recipient tests.

- ftpserver.pl: Corrected SMTP QUIT response to be more realistic

Daniel Stenberg (20 Sep 2013)
- curl_easy_setopt.3: clarify that TIMEOUT and TIMEOUT_MS set the same value

- [Kim Vandry brought this change]

  Documented --dns-* options in curl manpage

Steve Holme (20 Sep 2013)
- pop3: Added basic SASL XOAUTH2 support
  
  Added the ability to use an XOAUTH2 bearer token [RFC6750] with POP3 for
  authentication using RFC6749 "OAuth 2.0 Authorization Framework".
  
  The bearer token is expected to be valid for the user specified in
  conn->user. If CURLOPT_XOAUTH2_BEARER is defined and the connection has
  an advertised auth mechanism of "XOAUTH2", the user and access token are
  formatted as a base64 encoded string and sent to the server as
  "AUTH XOAUTH2 <bearer token>".

- curl: Added clarification to the --mail options in the --help output
  
  ... that these options apply to SMTP only.

- ftpserver.pl: Moved SMTP RCPT response text into command handler

- tests: Added SMTP invalid --mail-from test

Nick Zitzmann (19 Sep 2013)
- darwinssl: enable BEAST workaround on iOS 7 & later
  
  iOS 7 finally added the option to enable 1/n-1 when using TLS 1.0
  and a CBC cipher, so we now always turn that on unless the user
  manually turns it off using CURLSSLOPT_ALLOW_BEAST.
  
  It appears Apple also added some new PSK ciphers, but no interface to
  use them yet, so we at least support printing them if we find them.

Steve Holme (19 Sep 2013)
- tests: Updated SMTP AUTH tests to use the new AUTH directive
  
  ...rather than specify a customised EHLO response.

- tests: Corrected test913 as the QUIT response is received

- tests: Added SMTP large message SIZE test

- ftpserver.pl: Updated email regex from commit 98f7ca7e971006
  
  ...to not be as strict as it was rejecting valid numeric email
  addresses.

- tests: Fixed smtp mail from addresses

- ftpserver.pl: Standardised CAPA and AUTH responses

- ftpserver.pl: Corrected POP3 QUIT reply to be more realistic

- runtests.pl: Fixed syntax error in commit c873375123343e
  
  Possible unintended interpolation in string at line 796

- runtests.pl: Fixed smtp mail from address
  
  Following changes to ftpserver.pl fixed the mail from address to be a
  correctly formatted address otherwise the server response will be 501
  Invalid address.

- ftpserver.pl: Fixed syntax error in commit 98f7ca7e971006
  
  Can't modify constant item in scalar assignment line 779, near "0;"

- ftpserver.pl: Expanded the SMTP MAIL handler to validate messages
  
  MAIl_smtp() will now check for a correctly formatted FROM address as
  well as the optional SIZE parameter comparing it against the server
  capability when specified.

  Additionally, corrected some very, very minor coding style errors.

- tests: Fixed test 1406 following recent changes in ftpserver.pl
  
  By default the mail server doesn't send the SIZE capability but instead
  it has to be specified as a supported capability.

- tests: Added test for SMTP SIZE capability

- ftpserver.pl: Added the ability to include spaces in capabilities
  
  For example:
  
  CAPA "SIZE 1048576" 8BITMIME BINARYMIME

- NI_MAXSERV: remove all use of it
  
  Solaris with the SunStudio Compiler is reportedly missing this define,
  but as we're using it without any good reason on all the places it was
  used I've now instead switched to just use sensible buffer sizes that
  fit a 32 bit decimal number. Which also happens to be smaller than the
  common NI_MAXSERV value which is 32 on most machines.

  Additionally added the directive to the FILEFORMAT document.

- ftpserver: Reworked CAPA support to allow for specifying the capabilities
  
  Renamed SUPPORTCAPA to CAPA and added support for specifying a list of
  supported capabilities to return to the client.
  
  Additionally added the directive to the FILEFORMAT document.

- ftpserver.pl: Corrected POP3 LIST as message numbers should be contiguous
  
  The message numbers given in the LIST response are an index into the
  list, which are only valid for the current session, rather than being a
  unique message identifier. An index would only be missing from the LIST
  response if a DELE command had been issued within the same session and
  had not been committed by the end of session QUIT command. Once
  committed the POP3 server will regenerate the message numbers in the
  next session to be contiguous again. As such our LIST response should
  list message numbers contiguously until we support a DELE command in the
  same session.
  
  Should a POP3 user require the unique message ID for any or all
  messages then they should use the extended UIDL command. This command
  will be supported by the test ftpserver in an upcoming commit.

  Pass password to OpenSSL engine by user interface
  
  Recent OpenSSL uses user interface abstraction to negotiate access to
  private keys in the cryprographical engines. An OpenSSL application is

  LDAP: fix bad free() when URL parsing failed
  
  When an error occurs parsing an LDAP URL, The ludp->lud_attrs[i] entries
  could be freed even though they sometimes point to data within an
  allocated area.
  
  This change introduces a lud_attrs_dup[] array for the duplicated string
  pointers, and it removes the unused lud_exts array.

- imap/smtp: Fixed incorrect SASL mechanism selection with XOAUTH2 servers
  
  XOAUTH2 would be selected in preference to LOGIN and PLAIN if the IMAP
  or SMTP server advertised support for it even though a user's password
  was supplied but bearer token wasn't.
  
  Modified the selection logic so that XOAUTH2 will only be selected if
  the server supports it and A) The curl user/libcurl programmer has
  specifically asked for XOAUTH via the ;AUTH=XOAUTH login option or 2)
  The bearer token is specified. Obviously if XOAUTH is asked for via
  the login option but no token is specified the user will receive a
  authentication failure which makes more sense than no known
  authentication mechanisms supported!

  The commit 7b074a460b64811 to CURL_CHECK_CA_BUNDLE in 7.31 (don't check

  works when cross-compiling, since ca and capath only ever get set to
  "no" when not cross-compiling, I attach a patch that works for me. Also
  in the cross-compilation case, no ca-path seems to be a better default
  (IMVHO) than empty ca-path.

  When waiting for a 100-continue response from the server, the

  We timeout code in multi_socket() allows code to run slightly before the
  actual timeout time, so for test 154 it could lead to the function being
  executed but refused in Curl_readwrite() and then the application would
  just sit idling forever.
  
  This was detected with runtests.pl -e on test 154.

  curl_easy_perform_ev: make it CURL_EXTERN
  
  I build curl.exe (using MingW) with '-DCURLDEBUG' and by importing from
  libcurl.dll.  Which means the new curl_easy_perform_ev() must be
  exported from libcurl.dll.

- CURLM_ADDED_ALREADY: new error code
  
  Doing curl_multi_add_handle() on an easy handle that is already added to
  a multi handle now returns this error code. It previously returned
  CURLM_BAD_EASY_HANDLE for this condition.

- multi_init: moved init code here from add_handle
  
  The closure_handle is "owned" by the multi handle and it is
  unconditional so the setting up of it should be in the Curl_multi_handle
  function rather than curl_multi_add_handle.

- multi: remove dns cache creation code from *add_handle
  
  As it is done unconditionally in multi_init() this code will never run!

- curl_easy_perform_ev: debug/test function
  
  This function is meant to work *exactly* as curl_easy_perform() but will
  use the event-based libcurl API internally instead of
  curl_multi_perform(). To avoid relying on an actual event-based library
  and to not use non-portable functions (like epoll or similar), there's a
  rather inefficient emulation layer implemented on top of Curl_poll()
  instead.
  
  There's currently some convenience logging done in curl_easy_perform_ev
  which helps when tracking down problems. They may be suitable to remove
  or change once things seem to be fine enough.
  
  curl has a new --test-event option when built with debug enabled that
  then uses curl_easy_perform_ev() instead of curl_easy_perform(). If
  built without debug, using --test-event will only output a warning
  message.
  
  NOTE: curl_easy_perform_ev() is not part if the public API on purpose.
  It is only present in debug builds of libcurl and MUST NOT be considered
  stable even then. Use it for libcurl-testing purposes only.
  
  runtests.pl now features an -e command line option that makes it use
  --test-event for all curl command line tests. The man page is updated.

  url: handle arbitrary-length username and password before '@'
  
  libcurl quietly truncates usernames, passwords, and options from
  before an '@' sign in a URL to 255 (= MAX_CURL_PASSWORD_LENGTH - 1)
  characters to fit in fixed-size buffers on the stack.  Allocate a
  buffer large enough to fit the parsed fields on the fly instead to
  support longer passwords.
  
  After this change, there are no more uses of MAX_CURL_OPTIONS_LENGTH
  left, so stop defining that constant while at it.  The hardcoded max
  username and password length constants, on the other hand, are still
  used in HTTP proxy credential handling (which this patch doesn't
  touch).

  url: handle exceptional cases first in parse_url_login()
  
  Instead of nesting "if(success)" blocks and leaving the reader in
  suspense about what happens in the !success case, deal with failure
  cases early, usually with a simple goto to clean up and return from
  the function.
  
  No functional change intended.  The main effect is to decrease the
  indentation of this function slightly.

- [Jonathan Nieder brought this change]

  Curl_setopt: handle arbitrary-length username and password
  
  libcurl truncates usernames, passwords, and options set with
  curl_easy_setopt to 255 (= MAX_CURL_PASSWORD_LENGTH - 1) characters.
  This doesn't affect the return value from curl_easy_setopt(), so from
  the caller's point of view, there is no sign anything strange has
  happened, except that authentication fails.
  
  For example:
  
    # Prepare a long (300-char) password.
    s=0123456789; s=$s$s$s$s$s$s$s$s$s$s; s=$s$s$s;
    # Start a server.
    nc -l -p 8888 | tee out & pid=$!
    # Tell curl to pass the password to the server.
    curl --user me:$s http://localhost:8888 & sleep 1; kill $pid
    # Extract the password.
    userpass=$(
  	awk '/Authorization: Basic/ {print $3}' <out |
  	tr -d '\r' |
  	base64 -d
    )
    password=${userpass#me:}
    echo ${#password}
  
  Expected result: 300
  Actual result: 255
  
  The fix is simple: allocate appropriately sized buffers on the heap
  instead of trying to squeeze the provided values into fixed-size
  on-stack buffers.

- [Jonathan Nieder brought this change]

  netrc: handle longer username and password
  
  libcurl truncates usernames and passwords it reads from .netrc to
  LOGINSIZE and PASSWORDSIZE (64) characters without any indication to
  the user, to ensure the values returned from Curl_parsenetrc fit in a
  caller-provided buffer.
  
  Fix the interface by passing back dynamically allocated buffers
  allocated to fit the user's input.  The parser still relies on a
  256-character buffer to read each line, though.
  
  So now you can include an ~246-character password in your .netrc,
  instead of the previous limit of 63 characters.

  This makes it possible to increase the size of the buffers when needed

- [Jonathan Nieder brought this change]

  url: use goto in create_conn() for exception handling
  
  Instead of remembering before each "return" statement which temporary
  allocations, if any, need to be freed, take care to set pointers to
  NULL when no longer needed and use a goto to a common block to exit
  the function and free all temporaries.
  
  No functional change intended.  Currently the only temporary buffer in
  this function is "proxy" which is already correctly freed when
  appropriate, but there will be more soon.

- [Jonathan Nieder brought this change]

  sasl: allow arbitrarily long username and password
  
  Use appropriately sized buffers on the heap instead of fixed-size

  MAX_CURL_PASSWORD_LENGTH), so no functional change inteded yet.

- urlglob: better detect unclosed braces, empty lists and overflows
  
  A rather big overhaul and cleanup.
  
  1 - curl wouldn't properly detect and reject globbing that ended with an
  open brace if there were brackets or braces before it. Like "{}{" or
  "[0-1]{"
  
  2 - curl wouldn't properly reject empty lists so that "{}{}" would
  result in curl getting (nil) strings in the output.
  
  3 - By using strtoul() instead of sscanf() the code will now detected
  over and underflows. It now also better parses the step argument to only
  accept positive numbers and only step counters that is smaller than the
  delta between the maximum and minimum numbers.
  
  4 - By switching to unsigned longs instead of signed ints for the
  counters, the max values for []-ranges are now very large (on 64bit
  machines).
  
  5 - Bumped the maximum number of globs in a single URL to 100 (from 10)
  
  6 - Simplified the code somewhat and now it stores fixed strings as
  single- entry lists. That's also one of the reasons why I did (5) as now
  all strings between "globs" will take a slot in the array.
  
  Added test 1234 and 1235 to verify. Updated test 87.

  With everything being struct SessionHandle pointers now, this rename
  makes multi.c use the library-wide practise of calling that pointer

- SessionHandle: the protocol specific pointer is now a void *
  
  All protocol handler structs are now opaque (void *) in the
  SessionHandle struct and moved in the request-specific sub-struct
  'SingleRequest'. The intension is to keep the protocol specific
  knowledge in their own dedicated source files [protocol].c etc.
  
  There's some "leakage" where this policy is violated, to be addressed at
  a later point in time.

- urldata: clean up the use of the protocol specific structs
  
  1 - always allocate the struct in protocol->setup_connection. Some
  protocol handlers had to get this function added.
  
  2 - always free at the end of a request. This is also an attempt to keep
  less memory in the handle after it is completed.

- LIBCURL-STRUCTS: new document
  
  This is the first version of this new document, detailing the seven
  perhaps most important internal structs in libcurl source code:
  
    1.1 SessionHandle
    1.2 connectdata
    1.3 Curl_multi
    1.4 Curl_handler
    1.5 conncache
    1.6 Curl_share
    1.7 CookieInfo

- CONTRIBUTE: minor language polish

- FTP: when EPSV gets a 229 but fails to connect, retry with PASV
  
  This is a regression as this logic used to work. It isn't clear when it
  broke, but I'm assuming in 7.28.0 when we went all-multi internally.
  
  This likely never worked with the multi interface. As the failed
  connection is detected once the multi state has reached DO_MORE, the
  Curl_do_more() function was now expanded somewhat so that the
  ftp_do_more() function can request to go "back" to the previous state
  when it makes another attempt - using PASV.
  
  Added test case 1233 to verify this fix. It has the little issue that it
  assumes no service is listening/accepting connections on port 1...

- md5: remove use of CommonCrypto-to-OpenSSL macros for the benefit of Leopard
  
  For some reason, OS X 10.5's GCC suddenly stopped working correctly with
  macros that change MD5_Init etc. in the code to CC_MD5_Init etc., so I
  worked around this by removing use of the macros and inserting static
  functions that just call CommonCrypto's implementations of the functions
  instead.

- formadd: wrong pointer for file name when CURLFORM_BUFFERPTR used
  
  The internal function that's used to detect known file extensions for
  the default Content-Type got the the wrong pointer passed in when
  CURLFORM_BUFFER + CURLFORM_BUFFERPTR were used. This had the effect that
  strlen() would be used which could lead to an out-of-bounds read (and
  thus segfault). In most cases it would only lead to it not finding or
  using the correct default content-type.
  
  It also showed that test 554 and test 587 were testing for the
  previous/wrong behavior and now they're updated as well.

- multi: remove data->state.current_conn struct field
  
  Not needed

- multi: remove the one_easy struct field
  
  Since the merge of SessionHandle with Curl_one_easy, this indirection
  isn't used anymore.

- multi: rename all Curl_one_easy to SessionHandle

- multi: remove the multi_pos struct field
  
  Since Curl_one_easy is really a SessionHandle now, this indirection
  doesn't exist anymore.

- multi: remove easy_handle struct field
  
  It isn't needed anymore

- multi: remove 'Curl_one_easy' struct, phase 1
  
  The motivation for having a separate struct that keep track of an easy
  handle when using the multi handle was removed when we switched to
  always using the multi interface internally. Now they were just two
  separate struct that was always allocated for each easy handle.
  
  This first step just moves the Curl_one_easy struct members into the
  SessionHandle struct and hides this somehow (== keeps the source code
  changes to a minimum) by defining Curl_one_easy to SessionHandle
  
  The biggest changes in this commit are:
  
   1 - the linked list of easy handles had to be changed somewhat due
       to the new struct layout. This made the main linked list pointer
       get renamed to 'easyp' and there's also a new pointer to the last
       node, called easylp. It is no longer circular but ends with ->next
       pointing to NULL. New nodes are still added last.
  
   2 - easy->state is now called easy->mstate to avoid name collision

  Add in the files needed to build libcurl shared images on VMS.
  
  Update the packages/vms/readme file to be current.
  
  Also some files for the GNV based build were either missing or needed an
  update.
  
  curl_crtl_init.c is a special file that is run before main() to
  set up the proper C runtime behavior.
  
  generate_vax_transfer.com generates the VAX transfer vector modules from
  the gnv_libcurl_symbols.opt file.
  
  gnv_conftest.c_first is a helper file needed for configure scripts to
  come up with the expected answers on VMS.
  
  gnv_libcurl_symbols.opt is the public symbols for the libcurl shared
  image.
  
  gnv_link_curl.com builds the shared libcurl image and rebuilds other
  programs to use it.
  
  macro32_exactcase.patch is a hack to make a local copy of the VMS Macro32
  assembler case sensitive, which is needed to build the VAX transfer modules.
  
  report_openssl_version.c is a tool for help verify that the libcurl
  shared image is being built for a minium version of openssl.

  Two fixes:
  
  1. Force output file format to be stream-lf so that partial downloads

  This should have minor impact as if the file does not exist, it was

        correctly.
  
     b. VMS text files are read once to get the correct size

  The default VMS text formats do not contain either line-feed or

- Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage".
  
  This reverts commit 7ed25cc, reinstating commit 8ec2cb5.
  
  As of 18-jul-2013 we still do have code in libcurl that makes use of these
  memory functions. Commit 8ec2cb5 comment still applies and is yet valid.
  
  These memory functions are solely used in Windows builds, so all related
  code is protected with '#ifdef WIN32' preprocessor conditional compilation
  directives.
  
  Specifically, wcsdup() _wcsdup() are used when building a Windows target with
  UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case
  when building a Windows UNICODE target with Windows native SSL/TLS support
  enabled.
  
  Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage
  of these is hidden behind _tcsdup() which is MS way of dealing with code
  that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS
  header files and those compatible from other compilers use this preprocessor
  conditional compilation directive in order to select at compilation time
  whether 'wide' or 'ansi' MS API functions are used.
  
  Without this code, Windows build targets with Windows native SSL/TLS support
  enabled and MemoryTracking support enabled misbehave in tracking memory usage,
  regardless of being a UNICODE enabled build or not.

- formpost: better random boundaries
  
  When doing multi-part formposts, libcurl used a pseudo-random value that
  was seeded with time(). This turns out to be bad for users who formpost
  data that is provided with users who then can guess how the boundary
  string will look like and then they can forge a different formpost part
  and trick the receiver.
  
  My advice to such implementors is (still even after this change) to not
  rely on the boundary strings being cryptographically strong. Fix your
  code and logic to not depend on them that much!
  
  I moved the Curl_rand() function into the sslgen.c source file now to be
  able to take advantage of the SSL library's random function if it
  provides one. If not, try to use the RANDOM_FILE for seeding and as a
  last resort keep the old logic, just modified to also add microseconds
  which makes it harder to properly guess the exact seed.
  
  The formboundary() function in formdata.c is now using 64 bit entropy
  for the boundary and therefore the string of dashes was reduced by 4
  letters and there are 16 hex digits following it. The total length is
  thus still the same.

  When the c-ares based resolver backend failed to resolve a name, it

  [hostname] was used and that name resolving failed.
  
  Now we use the hostname used in the actual resolve attempt in the error
  message as well.

- ossl_recv: check for an OpenSSL error, don't assume
  
  When we recently started to treat a zero return code from SSL_read() as
  an error we also got false positives - which primarily looks to be
  because the OpenSSL documentation is wrong and a zero return code is not
  at all an error case in many situations.
  
  Now ossl_recv() will check with ERR_get_error() to see if there is a
  stored error and only then consider it to be a true error if SSL_read()
  returned zero.

  If a program would give a string like "%FF" to curl_easy_unescape() but

  ossl_recv: SSL_read() returning 0 is an error too
  
  SSL_read can return 0 for "not successful", according to the open SSL
  documentation: http://www.openssl.org/docs/ssl/SSL_read.html

- [Mike Giancola brought this change]

  ossl_send: SSL_write() returning 0 is an error too
  
  We found that in specific cases if the connection is abruptly closed,
  the underlying socket is listed in a close_wait state. We continue to
  call the curl_multi_perform, curl_mutli_fdset etc. None of these APIs
  report the socket closed / connection finished.  Since we have cases
  where the multi connection is only used once, this can pose a problem
  for us. I've read that if another connection was to come in, curl would
  see the socket as bad and attempt to close it at that time -
  unfortunately, this does not work for us.
  
  I found that in specific situations, if SSL_write returns 0, curl did
  not recognize the socket as closed (or errored out) and did not report
  it to the application. I believe we need to change the code slightly, to
  check if ssl_write returns 0. If so, treat it as an error - the same as
  a negative return code.

  cookies: only consider full path matches
  
  I found a bug which cURL sends cookies to the path not to aim at.
  For example:
  - cURL sends a request to http://example.fake/hoge/
  - server returns cookie which with path=/hoge;
    the point is there is NOT the '/' end of path string.
  - cURL sends a request to http://example.fake/hogege/ with the cookie.
  
  The reason for this old "feature" is because that behavior is what is
  described in the original netscape cookie spec:

- DOCS: Added information about login options to CURLOPT_USERPWD

- DOCS: Added information about login options in the URL

- url: Fixed missing length check in parse_proxy()
  
  Commit 11332577b3cb removed the length check that was performed by the
  old scanf() code.

- url: Fixed crash when no username or password supplied for proxy
  
  Fixed an issue in parse_proxy(), introduced in commit 11332577b3cb,
  where an empty username or password (For example: http://:@example.com)
  would cause a crash.

- url: Removed unused text length constants

- url: Updated proxy URL parsing to use parse_login_details()

- url: Tidy up of setstropt_userpwd() parameters
  
  Updated the naming convention of the login parameters to match those of
  other functions.

- url: Tidy up of code and comments following recent changes
  
  Tidy up of variable names and comments in setstropt_userpwd() and
  parse_login_details().

- url: Simplified setstropt_userpwd() following recent changes
  
  There is no need to perform separate clearing of data if a NULL option
  pointer is passed in. Instead this operation can be performed by simply
  not calling parse_login_details() and letting the rest of the code do
  the work.

- url: Correction to scope of if statements when setting data

- url: Fixed memory leak in setstropt_userpwd()
  
  setstropt_userpwd() was calling setstropt() in commit fddb7b44a79d to
  set each of the login details which would duplicate the strings and
  subsequently cause a memory leak.

- tool_paramhlp: Fixed options being included in username
  
  Fix to prevent the options from being displayed when curl requests the
  user's password if the following command line is specified:
  
  --user username;options

- url: Added support for parsing login options from the CURLOPT_USERPWD
  
  In addition to parsing the optional login options from the URL, added
  support for parsing them from CURLOPT_USERPWD, to allow the following
  supported command line:
  
  --user username:password;options

- url: Added bounds checking to parse_login_details()
  
  Added bounds checking when searching for the separator characters within
  the login string as this string may not be NULL terminated (For example
  it is the login part of a URL). We do this in preference to allocating a
  new string to copy the login details into which could then be passed to
  parse_login_details() for performance reasons.

- url: Added size_t cast to pointer based length calculations

- url: Corrected minor typo in comment

  zero. Another recv attempt could block the connection if it was
  not closed. This workaround abuses exceptfds in conjunction with

  Test 591 and 592 are updated accordingly.

- FTP: wait on both connections during active STOR state
  
  When doing PORT and upload (STOR), this function needs to extract the
  file descriptor for both connections so that it will respond immediately
  when the server eventually connects back.
  
  This flaw caused active connections to become unnecessary slow but they
  would still often work due to the normal polling on a timeout. The bug
  also would not occur if the server connected back very fast, like when
  testing on local networks.

  connect: treat an interface bindlocal() problem as a non-fatal error
  
  I am using curl_easy_setopt(CURLOPT_INTERFACE, "if!something") to force
  transfers to use a particular interface but the transfer fails with
  CURLE_INTERFACE_FAILED, "Failed binding local connection end" if the
  interface I specify has no IPv6 address. The cause is as follows:
  
  The remote hostname resolves successfully and has an IPv6 address and an
  IPv4 address.
  
  cURL attempts to connect to the IPv6 address first.
  
  bindlocal (in lib/connect.c) fails because Curl_if2ip cannot find an
  IPv6 address on the interface.
  
  This is a fatal error in singleipconnect()
  
  This change will make cURL try the next IP address in the list.
  
  Also included are two changes related to IPv6 address scope:
  
  - Filter the choice of address in Curl_if2ip to only consider addresses
  with the same scope ID as the connection address (mismatched scope for
  local and remote address does not result in a working connection).
  
  - bindlocal was ignoring the scope ID of addresses returned by
  Curl_if2ip . Now it uses them.

  This workaround fixes an issue on MinGW/Msys regarding the Perl

  their corresponding PIDs, but sockfilt (and other servers) wrote the
  Windows PID into their PID-files. Since this PID is useless to the
  testsuite, the write_pidfile function was changed to search for the
  Msys PID and write that into the PID-file.

  The Microsoft knowledge-base article

  The last remaining code piece that still used FTPSENDF now uses PPSENDF.
  In the problematic case, a PREQUOTE series was done on a re-used
  connection when Curl_pp_init() hadn't been called so it had messed up
  pointers. The init call is done properly from Curl_pp_sendf() so this
  change fixes this particular crash.

- test1509: verify proxy header response headers count
  
  Modified sws to support and use custom CONNECT responses instead of the
  previously naive hard-coded version. Made the HTTP test server able to
  extract test case number from the host name in a CONNECT request by
  finding the number after the last dot. It makes 'machine.moo.123' use
  test case 123.
  
  Adapted a larger amount of tests to the new <connect> style.

- NTLM: fix several NTLM code paths memory leaks

- WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage
  
  As of 25-mar-2013 wcsdup() _wcsdup() and _tcsdup() are only used in
  WIN32 specific code, so tracking of these has not been extended for
  other build targets. Without this fix, memory tracking system on
  WIN32 builds, when using these functions, would provide misleading
  results.
  
  In order to properly extend this support for all targets curl.h
  would have to define curl_wcsdup_callback prototype and consequently
  wchar_t should be visible before that in curl.h.  IOW curl_wchar_t
  defined in curlbuild.h and this pulling whatever system header is
  required to get wchar_t definition.
  
  Additionally a new curl_global_init_mem() function that also receives
  user defined wcsdup() callback would be required.

- HTTP proxy: insert slash in URL if missing
  
  curl has been accepting URLs using slightly wrong syntax for a long
  time, such as when completely missing as slash "http://example.org" or
  missing a slash when a query part is given
  "http://example.org?q=foobar".
  
  curl would translate these into a legitimate HTTP request to servers,
  although as was shown in bug #1206 it was not adjusted properly in the
  cases where a HTTP proxy was used.
  
  Test 1213 and 1214 were added to the test suite to verify this fix.
  
  The test HTTP server was adjusted to allow us to specify test number in
  the host name only without using any slashes in a given URL.

- pipelining: Remove dead code.

- Multiple pipelines and limiting the number of connections.
  
  Introducing a number of options to the multi interface that
  allows for multiple pipelines to the same host, in order to
  optimize the balance between the penalty for opening new
  connections and the potential pipelining latency.
  
  Two new options for limiting the number of connections:
  
  CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections
  to the same host. When adding a handle that exceeds this limit,
  that handle will be put in a pending state until another handle is
  finished, so we can reuse the connection.
  
  CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total.
  When adding a handle that exceeds this limit,
  that handle will be put in a pending state until another handle is
  finished. The free connection will then be reused, if possible, or
  closed if the pending handle can't reuse it.
  
  Several new options for pipelining:
  
  CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a
  pipeline is "full" when a connection is to be reused, a new connection
  will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it.
  If not, the handle will be put in a pending state until a connection is
  ready (either free or a pipe got shorter).
  
  CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not
  be reused if it is currently processing a transfer with a content
  length that is larger than this.
  
  CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not
  be reused if it is currently processing a chunk larger than this.
  
  CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow
  pipelining.
  
  CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow
  pipelining.
  
  See the curl_multi_setopt() man page for details.

  tool_main.c: fix VMS global variable storage-class specifier
  
  An extern submits a psect and a global reference to the linker to point

  The use of the extern by itself does declare a psect but does not declare
  a globalsymbol. It does declare a globalref. But the linker needs one and
  only one globaldef or there is an error.

  imap: Updated ftpserver.pl to be more compliant, added new commands
  
  Enriched IMAP capabilities of ftpserver.pl in order to be able to
  add tests for the new IMAP features.
  
  * Added support for APPEND - Saves uploaded data to log/upload.$testno
  * Added support for LIST - Returns the contents of <reply/> section in
    the current test, like e.g FETCH.
  * Added support for STORE - Returns hardcoded updated flags
  * Changed handling of SELECT - Returns much more information in the
    usual set of untagged responses; uses hardcoded data from an example
    in the IMAP RFC
  * Changed handling of FETCH - Fixed response format

- imap: Added check for empty UID in FETCH command
  
  As the UID has to be specified by the user for the FETCH command to work

  EXAMINE which have responses that cannot be easily identified. An
  extra check has been provided for them so that any untagged responses
  are accepted for them.

- pop3: Fixed unnecessary parent structure reference
  
  Updated pop3 code following recent imap changes.

- [Jiri Hruska brought this change]

  imap: Added custom request parsing
  
  Added imap_parse_custom_request() for parsing the CURLOPT_CUSTOMREQUEST
  parameter which URL decodes the value and separates the request from
  any parameters - This makes it easier to filter untagged responses
  by the request command.

  remove the hard returns.

- imap: Changed successful response logic in imap_state_append_resp()
  
  For consistency changed the logic of the imap_state_append_resp()
  function to test for an unsucessful continuation response rather than a
  succesful one.

- imap: Standardised imapcode condition tests
  
  For consistency changed two if(constant != imapcode) tests to be
  if(imapcode != constant).

- imap: Moved imap_append() to be with the other perform functions

- [Jiri Hruska brought this change]

  imap: Enabled APPEND support in imap_perform()
  
  Added logic in imap_perform() to perform an APPEND rather than SELECT
  and FETCH if an upload has been specified.

- [Jiri Hruska brought this change]

  imap: Implemented APPEND final processing
  
  The APPEND operation needs to be performed in several steps:
    1) We send "<tag> APPEND <mailbox> <flags> {<size>}\r\n"
    2) Server responds with continuation respose "+ ...\r\n"
    3) We start the transfer and send <size> bytes of data
    4) Only now we end the request command line by sending "\r\n"
    5) Server responds with "<tag> OK ...\r\n"
  
  This commit performs steps 4 and 5, in the DONE phase, as more
  processing is required after the transfer.

- [Jiri Hruska brought this change]

  imap: Added APPEND perform and response handler functions
  
  Added imap_append() function to initiate upload and imap_append_resp()
  to handle the continuation response and start the transfer.

  Accidentally lost the result code in imap_state_capability() and
  imap_state_login() with commit b06a78622609.

- imap: Another minor comment addition / tidy up

- imap: Updated the coding style for state changes after a send operation
  
  Some state changes would be performed after a failure test that
  performed a hard return, whilst others would be performed within a test
  for success. Updated the code, for consistency, so all instances are
  performed within a success test.

- pop3 / smtp: Small comment tidy up

  imap: Fixed error code returned for invalid FETCH response
  
  If the FETCH command does not result in an untagged response the the
  UID is probably invalid. As such do not return CURLE_OK.

- [Jiri Hruska brought this change]

  imap: Added processing of the final FETCH responses
  
  Not processing the final FETCH responses was not optimal, not only
  because the response code would be ignored but it would also leave data
  unread on the socket which would prohibit connection reuse.

- [Jiri Hruska brought this change]

  imap: Introduced FETCH_FINAL state for processing final fetch responses
  
  A typical FETCH response can be broken down into four parts:
  
    1) "* <uid> FETCH (<what> {<size>}\r\n", using continuation syntax
    2) <size> bytes of the actual message
    3) ")\r\n", finishing the untagged response
    4) "<tag> OK ...", finishing the command
  
  Part 1 is read in imap_fetch_resp(), part 2 is consumed in the PERFORM
  phase by the transfer subsystem, parts 3 and 4 are currently ignored.

- imap: fix autobuild warning
  
  Removed whitespace from imap_perform()

  for consistency with the response function.

- imap: Updated the coding style of imap_state_servergreet_resp()
  
  Updated the coding style, in this function, to be consistant with other
  response functions rather then performing a hard return on failure.

- imap: Reversed the logic of the (un)successful tagged SELECT response
  
  Reversed the logic of the unsuccessful vs successful tagged SELECT
  response in imap_state_select_resp() to be more logical to read.

- imap: Reversed the logic of the (un)successful tagged CAPABILITY response
  
  Reversed the logic of the unsuccessful vs successful tagged CAPABILITY
  response in imap_state_capability_resp() to be more logical to read.

- imap: Corrected char* references with char *
  
  Corrected char* references made in commit: 709b3506cd9b.

- [Jiri Hruska brought this change]

  imap: Added processing of more than one response when sent in same packet
  
  Added a loop to imap_statemach_act() in which Curl_pp_readresp() is
  called until the cache is drained. Without this multiple responses
  received in a single packet could result in a hang or delay.

- [Jiri Hruska brought this change]

  imap: Added filtering of CAPABILITY and FETCH untagged responses
  
  Only responses that contain "CAPABILITY" and "FETCH", respectively,
  will be sent to their response handler.

- [Jiri Hruska brought this change]

  imap: Added a helper function for upcoming untagged response filtering
  
  RFC 3501 states that "the client MUST be prepared to accept any response
  at all times" yet we assume anything received with "* " at the beginning
  is the untagged response we want.
  
  Introduced a helper function that checks whether the input looks like a
  response to specified command, so that we may filter the ones we are
  interested in according to the current state.

- [Jiri Hruska brought this change]

  imap: Moved CAPABILITY response handling to imap_state_capability_resp()
  
  Introduced similar handling to the FETCH responses, where even the
  untagged data responses are handled by the response handler of the
  individual state.

  imap: Added the ability to FETCH a specific UID and SECTION
  
  Updated the FETCH command to send the UID and SECTION parsed from the
  URL. By default the BODY specifier doesn't include a section, BODY[] is
  now sent whereas BODY[TEXT] was previously sent. In my opinion
  retrieving just the message text is rarely useful when dealing with
  emails, as the headers are required for example, so that functionality
  is not retained. In can however be simulated by adding SECTION=TEXT to
  the URL.
  
  Also updated test801 and test1321 due to the BODY change.

  pingpong: Introduce Curl_pp_moredata()
  
  A simple function to test whether the PP is not sending and there are
  still more data in its receiver cache. This will be later utilized to:
  
  1) Change Curl_pp_multi_statemach() and Curl_pp_easy_statemach() to
     not test socket state and just call user's statemach_act() function
     when there are more data to process, because otherwise the task would
     just hang, waiting for more data from the socket.
  
  2) Allow PP users to read multiple responses by looping as long as there
     are more data available and current phase is not finished.
     (Currently needed for correct processing of IMAP SELECT responses.)

  Instead of just abusing the pseudo-randomizer from Curl_FormBoundary(),
  this now uses Curl_ossl_random() to get entropy.

- email: Tidy up before additional IMAP work
  
  Replaced two explicit comparisons of CURLE_OK with boolean alternatives.
  
  General tidy up of comments.

- smtp: Removed duplicate pingpong structure initialisation
  
  The smtp_connect() function was setting the member variables of the
  pingpong structure twice, once before calling Curl_pp_init() and once
  after!

- move msvc IDE related files to 'vs' directory tree
  
  Use 'vs' directory tree given that 'vc' intended one clashes
  with an already existing build target in file Makefile.dist.

- install-sh: updated to support multiple source files as arguments
  
  Version 7.29.0 uses Makefiles generated with a newer version of the
  autotools than the previous 7.28.1. These Makefiles try to install
  e.g. header files by calling install-sh with multiple source files as
  arguments. The bundled install-sh is to old and does not support this.
  
  The problem only occurs, if install-sh is actually being used, ie. the
  platform install executable is to old or not usable. Example: Solaris
  10.
  
  The files install-sh and mkinstalldirs are now updated with the automake
  1.11.3 versions. A better fix might be to completely remove them from
  git and force the files to be added/created during buildconf.

  Fixed a null pointer reference when an empty challenge is passed to the
  Curl_sasl_create_digest_md5_message() function.

- darwinssl: Fix send glitchiness with data > 32 or so KB
  
  An ambiguity in the SSLWrite() documentation lead to a bad inference in the
  code where we assumed SSLWrite() returned the amount of bytes written to
  the socket, when that is not actually true; it returns the amount of data
  that is buffered for writing to the socket if it returns errSSLWouldBlock.
  Now darwinssl_send() returns CURLE_AGAIN if data is buffered but not written.

- pingpong.h: Fixed line length over 78 characters from b56c9eb48e3c

- pingpong: Optimised the endofresp() function
  
  Reworked the pp->endofresp() function so that the conndata, line and
  line length are passed down to it just as with Curl_client_write()
  rather than each implementation of the function having to query
  these values.
  
  Additionally changed the int return type to bool as this is more
  representative of the function's usage.

- email: Post STARTLS capability code tidy up (Part Three)
  
  Corrected the order of the upgrade_tls() functions and moved the handler
  upgrade and getsock() functions out from the middle of the state related
  functions.

- email: Post STARTLS capability code tidy up (Part Two)
  
  Corrected the order of the pop3_state_capa() / imap_state_capability()
  and the pop3_state_capa_resp() / imap_state_capability_resp() functions
  to match the execution order.

- smtp: Added support for the STARTTLS capability (Part Two)
  
  Added honoring of the tls_supported flag when starting a TLS upgrade
  rather than unconditionally attempting it. If the use_ssl flag is set
  to CURLUSESSL_TRY and the server doesn't support TLS upgrades then the
  connection will continue to authenticate. If this flag is set to
  CURLUSESSL_ALL then the connection will complete with a failure as it
  did previously.

Steve Holme (10 Feb 2013)
- pop3: Added support for the STLS capability (Part Two)
  
  Added sending of initial CAPA command before STLS is sent. This allows
  for the detection of the capability before trying to upgrade the
  connection.

- imap: Added support for the STARTTLS capability (Part Two)
  
  Added sending of initial CAPABILITY command before STARTTLS is sent.
  This allows for the detection of the capability before trying to
  upgrade the connection.

- smtp: Added support for the STLS capability (Part One)
  
  Introduced detection of the STARTTLS capability, in order to add support
  for TLS upgrades without unconditionally sending the STARTTLS command.
