  margin in the buffer.

  so that 'workend' is only assigned once within the function.

  Closes #802

- [Cory Benfield brought this change]

  http2: Add space between colon and header value
  
  curl's representation of HTTP/2 responses involves transforming the
  response to a format that is similar to HTTP/1.1. Prior to this change,
  curl would do this by separating header names and values with only a
  colon, without introducing a space after the colon.
  
  While this is technically a valid way to represent a HTTP/1.1 header
  block, it is much more common to see a space following the colon. This
  change introduces that space, to ensure that incautious tools are safely
  able to parse the header block.
  
  This also ensures that the difference between the HTTP/1.1 and HTTP/2
  response layout is as minimal as possible.

- openssl: stricter connection check function
  
  - In the case of recv error, limit returning 'connection still in place'
  to EINPROGRESS, EAGAIN and EWOULDBLOCK.
  
  This is an improvement on the parent commit which changed the openssl
  connection check to use recv MSG_PEEK instead of SSL_peek.
  
  Ref: https://github.com/curl/curl/commit/856baf5#comments

Daniel Stenberg (11 May 2016)
- [Anders Bakken brought this change]

  TLS: SSL_peek is not a const operation
  
  Calling SSL_peek can cause bytes to be read from the raw socket which in
  turn can upset the select machinery that determines whether there's data
  available on the socket.
  
  Since Curl_ossl_check_cxn only tries to determine whether the socket is
  alive and doesn't actually need to see the bytes SSL_peek seems like
  the wrong function to call.
  
  We're able to occasionally reproduce a connect timeout due to this
  bug. What happens is that Curl doesn't know to call SSL_connect again
  after the peek happens since data is buffered in the SSL buffer and thus
  select won't fire for this socket.
  
  Closes #795

Jay Satiro (9 May 2016)
- [Daniel Stenberg brought this change]

  TLS: move the ALPN/NPN enable bits to the connection
  
  Only protocols that actually have a protocol registered for ALPN and NPN
  should try to get that negotiated in the TLS handshake. That is only
  HTTPS (well, http/1.1 and http/2) right now. Previously ALPN and NPN
  would wrongly be used in all handshakes if libcurl was built with it
  enabled.

- libcurl-thread.3: openssl 1.1.0 is safe, and so is boringssl

- [Antonio Larrosa brought this change]

  connect: fix invalid "Network is unreachable" errors
  
  Sometimes, in systems with both ipv4 and ipv6 addresses but where the
  network doesn't support ipv6, Curl_is_connected returns an error
  (intermittently) even if the ipv4 socket connects successfully.
  
  This happens because there's a for-loop that iterates on the sockets but
  the error variable is not resetted when the ipv4 is checked and is ok.
  
  This patch fixes this problem by setting error to 0 when checking the
  second socket and not having a result yet.
  
  Fixes #794

- tool_cb_hdr: Fix --remote-header-name with schemeless URL
  
  - Move the existing scheme check from tool_operate.
  
  In the case of --remote-header-name we want to parse Content-disposition
  for a filename, but only if the scheme is http or https. A recent
  adjustment 0dc4d8e was made to account for schemeless URLs however it's
  not 100% accurate. To remedy that I've moved the scheme check to the
  header callback, since at that point the library has already determined
  the scheme.

- lib: include curl_printf.h as one of the last headers
  
  curl_printf.h defines printf to curl_mprintf, etc. This can cause
  problems with external headers which may use
  __attribute__((format(printf, ...))) markers etc.
  
  To avoid that they cause problems with system includes, we include
  curl_printf.h after any system headers. That makes the three last
  headers to always be, and we keep them in this order:
  
   curl_printf.h
   curl_memory.h
   memdebug.h
  
  None of them include system headers, they all do funny #defines.
  
  Reported-by: David Benjamin
  
  Fixes #743

- memdebug.h: remove inclusion of other headers
  
  Mostly because they're not needed, because memdebug.h is always included
  last of all headers so the others already included the correct ones.
  
  But also, starting now we don't want this to accidentally include any
  system headers, as the header included _before_ this header may add
  defines and other fun stuff that we won't want used in system includes.

- [Jay Satiro brought this change]

  curl -J: make it work even without http:// scheme on URL
  
  It does open up a miniscule risk that one of the other protocols that
  libcurl could use would send back a Content-Disposition header and then
  curl would act on it even if not HTTP.
  
  A future mitigation for this risk would be to allow the callback to ask
  libcurl which protocol is being used.
  
  Verified with test 1312
  
  Closes #760

- manpage-scan.pl: also verify the command line option docs
  
  This script now also scans src/tool_getparam.c, docs/curl.1 and
  src/tool_help.c and will warn if any of them lists a command line option
  not mentioned in one of the other places.

- curl: show the long option version of -q in the -h list

- curl: remove "--socks" as "--socks5" turned 8
  
  In commit 2e42b0a2524 (Jan 2008) we made the option "--socks" deprecated
  and it has not been documented since. The more explicit socks options
  (like --socks4 or --socks5) should be used.

- curl.1: document the deprecated --ftp-ssl option

- curl: remove --http-request
  
  It was mentioned as deprecated already in commit ae1912cb0d4 from
  1999. It has not been documented in this millennium.

- curl: mention --ntlm-wb in -h list

- curl: -h output lacked --proxy-header

- curl.1: document --ntlm-wb

- curl.1: document the long format of -q: --disable

- curl.1: mention the deprecated --krb4 option

- curl.1: document --ftp-ssl-reqd
  
  Even if deprecated, document it so that people will find it as old
  scripts may still use it.

- curl: use --telnet-option as documented
  
  The code said "telnet-options" but no documentation ever said so. It
  worked fine since the code is fine with a unique match of the first
  part.

- getparam: remove support for --ftpport
  
  It has been deprecated and undocumented since commit ad5ead8bed7 (Dec
  2003). --ftp-port is the proper long option name.

- curl: make --disable work as long form of -q
  
  To make the aliases list reflect reality.

- aliases: remove trailing space from capath string

- KNOWN_BUGS: fixed "5.6 Improper use of Autoconf cache variables"
  
  As of commit d9f3b365a3

- [Irfan Adilovic brought this change]

  configure: ac_cv_ -> curl_cv_ for write-only vars
  
  These configure vars are modified in a curl-specific way but never
  evaluated or loaded from cache, even though they are designated as
  _cv_. We could either implement proper AC_CACHE_CHECKs for them, or
  remove them completely.
  
  Fixes #603 as ac_cv_func_gethostbyname is no longer clobbered, and
  AC_CHECK_FUNC(gethostbyname...) will no longer spuriously succeed after
  the first configure run with caching.
  
  `ac_cv_func_strcasecmp` is curious, see #770.
  
  `eval "ac_cv_func_$func=yes"` can still cause problems as it works in
  tandem with AC_CHECK_FUNCS and then potentially modifies its result. It
  would be best to rewrite this test to use a new CURL_CHECK_FUNCS macro,
  which works the same as AC_CHECK_FUNCS but relies on caching the values
  of curl_cv_func_* variables, without modifiying ac_cv_func_*.

- [Irfan Adilovic brought this change]

  configure: ac_cv_ -> curl_cv_ for r/w vars
  
  These configure vars are modified in a curl-specific way and modified by
  the configure process, but are never loaded from cache, even though they
  are designated as _cv_. We should implement proper AC_CACHE_CHECKs for
  them eventually.

- [Irfan Adilovic brought this change]

  configure: ac_cv_func_clock_gettime -> curl_...
  
  This variable must not be cached in its current form, as any cached
  information will prevent the next configure run from determining the
  correct LIBS needed for the function. Thus, rename prefix `ac_cv_` to
  just `curl_`.

- [Irfan Adilovic brought this change]

  configure: ac_cv_ -> curl_cv_ for all cached vars
  
  This was automated by:
  
  sed -b -i -f <(ack -A1 AC_CACHE_CHECK | \
                 ack -o 'ac_cv_.*?\b' | \
                 sort -u | xargs -n1 bash -c \
                      'echo "s/$0/curl_cv_${0#ac_cv_}/g"') \
      $(git ls-files)
  
  This only changed the prefix for 16 variables actually checked with
  AC_CACHE_CHECK.

- [Karlson2k brought this change]

  sendf.c: added ability to call recv() before send() as workaround
  
  WinSock destroys recv() buffer if send() is failed. As result - server
  response may be lost if server sent it while curl is still sending
  request. This behavior noticeable on HTTP server short replies if
  libcurl use several send() for request (usually for POST request).
  To workaround this problem, libcurl use recv() before every send() and
  keeps received data in intermediate buffer for further processing.
  
  Fixes: #657
  Closes: #668

  http2: Ensure that http2_handle_stream_close is called
  
  This commit ensures that streams which was closed in on_stream_close
  callback gets passed to http2_handle_stream_close.  Previously, this
  might not happen.  To achieve this, we increment drain property to
  forcibly call recv function for that stream.
  
  To more accurately check that we have no pending event before shutting
  down HTTP/2 session, we sum up drain property into
  http_conn.drain_total.  We only shutdown session if that value is 0.
  
  With this commit, when stream was closed before reading response
  header fields, error code CURLE_HTTP2_STREAM is returned even if
  HTTP/2 level error is NO_ERROR.  This signals the upper layer that
  stream was closed by error just like TCP connection close in HTTP/1.

  very much fine.  This change introduce new error code
  CURLE_HTTP2_STREAM, which indicates stream error that only affects the
  relevant stream, and connection should be kept open.  The existing

  death blow to that define from everywhere.
  
  As a side-effect, making sure _MPRINTF_REPLACE is gone and not used, I
  made the lib tests in tests/libtest/ use curl_printf.h for its redefine
  magic and then subsequently the use of sprintf() got banned in the tests
  as well (as it is in libcurl internals) and I then replaced them all
  with snprintf().
  
  In the unlikely event that any users is actually using this define and
  gets sad by this change, it is very easily copied to the user's own

- build-wolfssl: Allow a broader range of ciphers (Visual Studio)
  
  This is an update to the build-time options used to build wolfSSL in
  Visual Studio for greater compatibility, and make it behave similar to
  the way OpenSSL 1.0.2 behaves. Starting in wolfSSL v3.6.6 static ciphers
  and SSLv3 are disabled by default at build time, but we can use both.
  
  - Enable static cipher suites TLS_ECDH_ and TLS_RSA_.
  
  - Enable SSLv3 hello. Though in libcurl we disable it by default at
  runtime, we make it available so the user can manually select it if
  necessary.

  GSS: make Curl_gss_log_error more verbose
  
  Also display the GSS_C_GSS_CODE (major code) when specified instead of
  only GSS_C_MECH_CODE (minor code).
  
  In addition, the old code was printing a colon twice after the prefix
  and also miscalculated the length of the buffer in between calls to
  gss_display_status (the length of ": " was missing).
  
  Also, gss_buffer is not guaranteed to be NULL terminated and thus need
  to restrict reading by its length.

- build-wolfssl: Update VS properties for wolfSSL v3.9.0
  
  - Do not use wolfSSL's sample user-setting files.
  
  wolfSSL starting in v3.9.0 has added their own sample user settings that
  are applied by default, but we don't use them because we have our own
  settings.
  
  - Do not use wolfSSL's Visual Studio Unicode character setting.
  
  wolfSSL Visual Studio projects use the Unicode character set however our
  settings and options imitate mingw build which does not use the Unicode
  character set. This does not appear to have any effect at the moment but
  better safe than sorry.
  
  
  These changes are backwards compatible with earlier versions.

Steve Holme (19 Mar 2016)
- build: Added missing Visual Studio filter files for VC10 onwards
  
  As these files don't need to contain references to the source files,
  although typically do, added basic files which only include three
  filters and don't require the project file generator to be modified.
  
  These files allow the source code to be viewed in the Solution Explorer
  in versions of Visual Studio from 2010 onwards in the same manner as
  previous versions did rather than one large view of files.

  warning C4701: potentially uninitialized local variable 'size' used

  'if(parsed)' and 'parsed' is only set after 'size' has been parsed.
  
  Anyway, lets keep the compiler happy.

Daniel Stenberg (18 Mar 2016)
- bump: the coming release is 7.48.0

- configure: use cpp -P when needed
  
  Since gcc 5, the processor output can get split up on multiple lines
  that made the configure script fail to figure out values from
  definitions. The fix is to use cpp -P, and this fix now first checks if
  cpp -P is necessary and then if cpp -P works before it uses that to
  extract defined values.
  
  Fixes #719

Steve Holme (18 Mar 2016)
- formdata.c: Fixed compilation warning
  
  formdata.c:390: warning: cast from pointer to integer of different size
  
  Introduced in commit ca5f9341ef this happens because a char*, which is
  32-bits wide in 32-bit land, is being cast to a curl_off_t which is
  64-bits wide where 64-bit integers are supported by the compiler.
  
  This doesn't happen in 64-bit land as a pointer is the same size as a
  curl_off_t.
  
  This fix doesn't address the fact that a 64-bit value cannot be used
  for CURLFORM_CONTENTLEN when set in a form array and compiled on a
  32-bit platforms, it does at least suppress the compilation warning.

- cookies: first n/v pair in Set-Cookie: is the cookie, then parameters
  
  RFC 6265 section 4.1.1 spells out that the first name/value pair in the
  header is the actual cookie name and content, while the following are
  the parameters.
  
  libcurl previously had a more liberal approach which causes significant
  problems when introducing new cookie parameters, like the suggested new
  cookie priority draft.
  
  The previous logic read all n/v pairs from left-to-right and the first
  name used that wassn't a known parameter name would be used as the
  cookie name, thus accepting "Set-Cookie: Max-Age=2; person=daniel" to be
  a cookie named 'person' while an RFC 6265 compliant parser should
  consider that to be a cookie named 'Max-Age' with an (unknown) parameter
  'person'.
  
  Fixes #709

- krb5: improved type handling to avoid clang compiler warnings

- url.c: fix clang warning: no newline at end of file

- curl_multi_wait: never return -1 in 'numfds'
  
  Such a return value isn't documented but could still happen, and the
  curl tool code checks for it. It would happen when the underlying
  Curl_poll() function returns an error. Starting now we mask that error
  as a user of curl_multi_wait() would have no way to handle it anyway.

  openssl: remove most BoringSSL #ifdefs.
  
  As of https://boringssl-review.googlesource.com/#/c/6980/, almost all of
  BoringSSL #ifdefs in cURL should be unnecessary:
  
  - BoringSSL provides no-op stubs for compatibility which replaces most
    #ifdefs.
  
  - DES_set_odd_parity has been in BoringSSL for nearly a year now. Remove
    the compatibility codepath.
  
  - With a small tweak to an extend_key_56_to_64 call, the NTLM code
    builds fine.
  
  - Switch OCSP-related #ifdefs to the more generally useful
    OPENSSL_NO_OCSP.
  
  The only #ifdefs which remain are Curl_ossl_version and the #undefs to
  work around OpenSSL and wincrypt.h name conflicts. (BoringSSL leaves
  that to the consumer. The in-header workaround makes things sensitive to
  include order.)
  
  This change errs on the side of removing conditionals despite many of
  the restored codepaths being no-ops. (BoringSSL generally adds no-op
  compatibility stubs when possible. OPENSSL_VERSION_NUMBER #ifdefs are
  bad enough!)

- mbedtls: Fix pinned key return value on fail
  
  - Switch from verifying a pinned public key in a callback during the
  certificate verification to inline after the certificate verification.
  
  The callback method had three problems:
  
  1. If a pinned public key didn't match, CURLE_SSL_PINNEDPUBKEYNOTMATCH
  was not returned.
  
  2. If peer certificate verification was disabled the pinned key
  verification did not take place as it should.
  
  3. (related to #2) If there was no certificate of depth 0 the callback
  would not have checked the pinned public key.
  
  Though all those problems could have been fixed it would have made the
  code more complex. Instead we now verify inline after the certificate
  verification in mbedtls_connect_step2.

- openssl: improved error detection/reporting
  
  ... by extracting the LIB + REASON from the OpenSSL error code. OpenSSL
  1.1.0+ returned a new func number of another cerfificate fail so this
  required a fix and this is the better way to catch this error anyway.

- openssl: for 1.1.0+ they now provide a SSLeay() macro of their own

- CURLOPT_RESOLVE.3: minor language polish

- configure: assume IPv6 works when cross-compiled
  
  The configure test uses AC_TRY_RUN to figure out if an ipv6 socket
  works, and testing like that doesn't work for cross-compiles. These days
  IPv6 support is widespread so a blind guess is probably more likely to
  be 'yes' than 'no' now.
  
  Further: anyone who cross-compiles can use configure's --disable-ipv6 to
  explicitly disable IPv6 and that also works for cross-compiles.
  
  Made happen after discussions in issue #594

- TODO: "Try to URL encode given URL"
  
  Closes #514

- ConnectionExists: only do pipelining/multiplexing when asked
  
  When an HTTP/2 upgrade request fails (no protocol switch), it would
  previously detect that as still possible to pipeline on (which is
  acorrect) and do that when PIPEWAIT was enabled even if pipelining was
  not explictily enabled.
  
  It should only pipelined if explicitly asked to.
  
  Closes #584

  lib: Prefix URLs with lower-case protocol names/schemes
  
  Before this patch, if a URL does not start with the protocol
  name/scheme, effective URLs would be prefixed with upper-case protocol
  names/schemes. This behavior might not be expected by library users or
  end users.
  
  For example, if `CURLOPT_DEFAULT_PROTOCOL` is set to "https". And the
  URL is "hostname/path". The effective URL would be
  "HTTPS://hostname/path" instead of "https://hostname/path".
  
  After this patch, effective URLs would be prefixed with a lower-case
  protocol name/scheme.

  http2: Ensure that http2_handle_stream_close is called
  
  Previously, when HTTP/2 is enabled and used, and stream has content
  length known, Curl_read was not called when there was no bytes left to
  read. Because of this, we could not make sure that
  http2_handle_stream_close was called for every stream. Since we use
  http2_handle_stream_close to emit trailer fields, they were
  effectively ignored. This commit changes the code so that Curl_read is
  called even if no bytes left to read, to ensure that
  http2_handle_stream_close is called for every stream.

  http2: Support trailer fields
  
  This commit adds trailer support in HTTP/2.  In HTTP/1.1, chunked
  encoding must be used to send trialer fields.  HTTP/2 deprecated any
  trandfer-encoding, including chunked.  But trailer fields are now
  always available.
  
  Since trailer fields are relatively rare these days (gRPC uses them
  extensively though), allocating buffer for trailer fields is done when
  we detect that HEADERS frame containing trailer fields is started.  We
  use Curl_add_buffer_* functions to buffer all trailers, just like we
  do for regular header fields.  And then deliver them when stream is
  closed.  We have to be careful here so that all data are delivered to
  upper layer before sending trailers to the application.
  
  We can deliver trailer field one by one using NGHTTP2_ERR_PAUSE
  mechanism, but current method is far more simple.
  
  Another possibility is use chunked encoding internally for HTTP/2
  traffic.  I have not tested it, but it could add another overhead.

  As POP3 final and continuation responses both begin with a + character,
  and both the finalcode and contcode variables in SASLprotoc are set as
  such, we cannot tell the difference between them when we are expecting
  an optional continuation from the server such as the following:
  
  + something else from the server
  +OK final response
  
  Disabled these tests until such a time we can tell the responses apart.

- tests: Corrected typos from commit ba4d8f7eba

- tests: Added OAUTHBEARER failure response tests

- oauth2: Support OAUTHBEARER failures sent as continuation responses
  
  According to RFC7628 a failure message may be sent by the server in a
  base64 encoded JSON string as a continuation response.
  
  Currently only implemented for OAUTHBEARER and not XAUTH2.

- tests: Renamed existing OAuth 2.0 (XOAUTH) tests

- tests: Added OAuth 2.0 (OAUTHBEARER) tests

- oauth2: Added support for OAUTHBEARER SASL mechanism to IMAP, POP3 and SNMP
  
  OAUTHBEARER is now the official "registered" SASL mechanism name for
  OAuth 2.0. However, we don't want to drop support for XOAUTH2 as some
  servers won't support the new mechanism yet.

- cleanup: general removal of TODO (and similar) comments
  
  They tend to never get updated anyway so they're frequently inaccurate
  and we never go back to revisit them anyway. We document issues to work
  on properly in KNOWN_BUGS and TODO instead.

  unit1603: Demote hash mismatch failure to a warning
  
  The hashes can vary between architectures (e.g. Sparc differs from x86_64).
  This is not a fatal problem but just reduces the coverage of these white-box
  tests, as the assumptions about into which hash bucket each key falls are no
  longer valid.

  Following the fix in commit d6d58dd558 it is necessary to re-introduce
  XOAUTH2 in the default enabled authentication mechanism, which was
  removed in commit 7b2012f262, otherwise users will have to specify
  AUTH=XOAUTH2 in the URL.
  
  Note: OAuth 2.0 will only be used when the bearer is specified.

- sasl: Don't choose OAuth 2.0 if mechanism not advertised
  
  Regression from commit 9e8ced9890 which meant if --oauth2-bearer was

  the mechanism would be chosen.

Daniel Stenberg (12 Nov 2015)
- runtests: more compact "System characteristics" output
  
  - no point in repeating curl features that is already listed as features

  cmake: Add missing feature macros in config header
  
  The curl_config.h file can be generated either from curl_config.h.cmake
  or curl_config.h.in, depending on whether you're building using CMake or
  the autotools.  The CMake template header doesn't include entries for
  all of the protocols that you can disable, which (I think) means that
  you can't actually disable those protocols when building via CMake.
  
  Closes #523

- [Douglas Creager brought this change]

  BoringSSL: Work with stricter BIO_get_mem_data()
  
  BoringSSL implements `BIO_get_mem_data` as a function, instead of a

  an explicit cast to grab the pointer as a `const char **`.

- build: Fix support for PKG_CONFIG
  
  - Allow the user to use PKG_CONFIG but not PKGCONFIG.
  
  Background:
  
  Last week in 14d5a86 a change was made to allow the user to set the
  PKGCONFIG variable. Today in 72d99f2 I supplemented that to allow the
  more common PKG_CONFIG as an alternative if PKGCONFIG is not set.
  
  Neither of those changes worked as expected because PKGCONFIG is
  occasionally reset in configure and by the CURL_CHECK_PKGCONFIG macro.
  Instead in this commit I take the approach that the user may set
  PKG_CONFIG only.

  gnutls: Support CURLOPT_KEYPASSWD
  
  The gnutls vtls back-end was previously ignoring any password set via
  CURLOPT_KEYPASSWD. Presumably this was because
  gnutls_certificate_set_x509_key_file did not support encrypted keys.
  
  gnutls now has a gnutls_certificate_set_x509_key_file2 function that
  does support encrypted keys. Let's determine at compile time whether the
  available gnutls supports this new function. If it does then use it to
  pass the password. If it does not then emit a helpful diagnostic if a
  password is set. This is preferable to the previous behaviour of just
  failing to read the certificate without giving a reason in that case.

  - Change the designator name we use to show the base64 encoded sha256
  hash of the server's public key from 'pinnedpubkey' to
  'public key hash'.
  
  Though the server's public key hash is only shown when comparing pinned

- nss: prevent NSS from incorrectly re-using a session
  
  Without this workaround, NSS re-uses a session cache entry despite the

  When the option is not used, libcurl will follow its usual plan of
  guessing from the hostname and falling back to 'http'.
