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.
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.
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.
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.
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tests, as the assumptions about into which hash bucket each key falls are no
longer valid.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.
Regression from commit 9e8ced9890 which meant if --oauth2-bearer was
specified but the SASL mechanism wasn't supported by the server then
the mechanism would be chosen.
- no point in repeating curl features that is already listed as features
from the curl -V output
- remove the port numbers/unix domain path from the output unless
verbose is used, as that is rarely interesting to users.
Added support to the OAuth 2.0 message function for host and port, in
order to accommodate the official OAUTHBEARER SASL mechanism which is
to be added shortly.
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.

info param but prior to this change it wrote -1.

- 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.

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

Though the server's public key hash is only shown when comparing pinned
public key hashes, the server's hash may not match one of the pinned.
Without this workaround, NSS re-uses a session cache entry despite the
server name does not match. This causes SNI host name to differ from
the actual host name. Consequently, certain servers (e.g. github.com)
respond by 400 to such requests.

was reinterpreted as type (struct HTTP *) which resulted in SIGSEGV in
Curl_add_buffer_free() after printing the "Connection cache is full,
closing the oldest one." message.
A previously working version of libcurl started to crash after it was
recompiled with the HTTP/2 support despite the HTTP/2 protocol was not
actually used. This commit makes it work again although I suspect the
root cause (reinterpreting session handle data of incompatible protocol)
still has to be fixed. Otherwise the same will happen when mixing FTP

This wasn't possible with the old curlsrc project filenames, but like

This is a new document to consolidate our thread safety information from

Each document's section on multi-threading will now point to this one.
Currently, libcurl rejects responses with "Content-Encoding: compress"
when CURLOPT_ACCEPT_ENCODING is set to "". I think that libcurl should
treat the Content-Encoding "compress" the same as other

just ignoring it.

HTTPS proxies:
An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a
secure connection with the proxy is established, the user agent uses the proxy
as usual, including sending CONNECT requests to instruct the proxy to establish
a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect
nearly all aspects of user-proxy communications as opposed to HTTP proxies that
receive all requests (including CONNECT requests) in vulnerable clear text.
With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS
sessions: the "outer" one between the user agent and the proxy and the "inner"
one between the user agent and the origin server (through the proxy). This
change adds supports for such nested sessions as well.
The secure connection with the proxy requires its own set of the usual
SSL/TLS-related options (their descriptions need polishing):
--proxy-cacert FILE CA certificate to verify peer against
--proxy-capath DIR CA directory to verify peer against
--proxy-cert CERT[:PASSWD] Client certificate file and password
--proxy-cert-type TYPE Certificate file type (DER/PEM/ENG)
--proxy-ciphers LIST SSL ciphers to use
--proxy-crlfile FILE Get a CRL list in PEM format from the given file
--proxy-insecure Allow connections to SSL sites without certs
--proxy-key KEY Private key file name
--proxy-key-type TYPE Private key file type (DER/PEM/ENG)
--proxy-pass PASS Pass phrase for the private key
--proxy-ssl-allow-beast Allow security flaw to improve interop
--proxy-sslv2 Use SSLv2
--proxy-sslv3 Use SSLv3
--proxy-tlsv1 Use TLSv1
--proxy-tlsuser USER TLS username
--proxy-tlspassword STRING TLS password
--proxy-tlsauthtype STRING TLS authentication type (default SRP)
All --proxy-foo options are independent from their --foo counterparts, except
--proxy-crlfile defaults to --crlfile and --proxy-capath defaults to --capath.
Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.
SOCKS proxy + HTTP/HTTPS proxy combination:
If both --socks* and --proxy options are given, Curl first connects to the
SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy.
Since we do prefix match using given header by application code
against header name pair in format "NAME:VALUE", and VALUE part can
contain ":", we have to careful about existence of ":" in header
parameter. ":" should be allowed to match HTTP/2 pseudo-header field,
and other use of ":" in header must be treated as error, and
curl_pushheader_byname should return NULL. This commit implements
this behaviour.
Advise that WinSSL in versions <= XP will not be able to connect to
servers that no longer support the legacy handshakes and algorithms used
by those versions, and to use an alternate backend like OpenSSL instead.

The symbol SSL3_MT_NEWSESSION_TICKET appears to have been introduced at
around openssl 0.9.8f, and the use of it in lib/vtls/openssl.c breaks
builds with older openssls (certainly with 0.9.8b, which is the latest
older version I have to try with).
** WORK-AROUND **
The introduced non-blocking general behaviour for Curl_proxyCONNECT()
didn't work for the data connection establishment unless it was very
fast. The newly introduced function argument makes it operate in a more
blocking manner, more like it used to work in the past. This blocking
approach is only used when the FTP data connecting through HTTP proxy.
Blocking like this is bad. A better fix would make it work more
asynchronously.

connection isn't closed.
%%
%% Draft 6
%%
- Save the last error only if it is an unrecoverable error.
Prior to this I saved the last error state in all cases; unfortunately
the logic to cover that in all cases would lead to some muddle and I'm
concerned that could then lead to a bug in the future so I've replaced
it by only recording an unrecoverable error and that state will persist.
- Do not recurse on renegotiation.
Instead we'll continue on to process any trailing encrypted data
received during the renegotiation only.
- Move the err checks in cleanup after the check for decrypted data.
In either case decrypted data is always returned but I think it's easier
to understand when those err checks come after the decrypted data check.
%%
%% Draft 7
%%
- Regardless of len value go directly to cleanup if there is an
unrecoverable error or a close_notify was already received. Prior to
this change we only acknowledged those two states if len != 0.
- Fix a bug in connection closed behavior: Set the error state in the
cleanup, because we don't know for sure it's an error until that time.
- (Related to above) In the case the connection is closed go "greedy"

Some servers will request a client certificate, but not require one.
This change allows libcurl to connect to such servers when using
schannel as its ssl/tls backend. When a server requests a client
certificate, libcurl will now continue the handshake without one,
rather than terminating the handshake. The server can then decide
if that is acceptable or not. Prior to this change, libcurl would
terminate the handshake, reporting a SEC_I_INCOMPLETE_CREDENTIALS
error.

Added a TOC to top of the document.
When CURL_SOCKET_BAD is returned in the callback, it should be treated

This check scans for fopen() with a mode string without 'b' present, as
it may indicate that an FOPEN_* define should rather be used.
- Change fopen calls to use FOPEN_READTEXT instead of "r" or "rt"
- Change fopen calls to use FOPEN_WRITETEXT instead of "w" or "wt"
This change is to explicitly specify when we need to read/write text.
Unfortunately 't' is not part of POSIX fopen so we can't specify it
directly. Instead we now have FOPEN_READTEXT, FOPEN_WRITETEXT.
Prior to this change we had an issue on Windows if an application that
uses libcurl overrides the default file mode to binary. The default file

Previously, after seeing upgrade to HTTP/2, we feed data followed by
upgrade response headers directly to nghttp2_session_mem_recv() in
Curl_http2_switched(). But it turns out that passed buffer, mem, is
part of stream->mem, and callbacks called by
nghttp2_session_mem_recv() will write stream specific data into
stream->mem, overwriting input data. This will corrupt input, and
most likely frame length error is detected by nghttp2 library. The
fix is first copy the passed data to HTTP/2 connection buffer,
httpc->inbuf, and call nghttp2_session_mem_recv().
The CURLOPT_COOKIE doc says it "sets the cookie header explicitly in the
outgoing request(s)." However there seems to be some user confusion
about cookie modification. Document that the cookies set by this option
are not modified by the cookie engine.

This function makes a platform-specific absolute path which uses

Coverity CID 1299424 identified dead code because of checks that could

This flaw was sort of detected by Coverity CID 1299425 which claimed the

Coverity CID 1299426 warned about possible NULL dereference otherwise,
but that would only ever happen if we get invalid HTTP/2 data with

With many easy handles using the same connection for multiplexing, it is
important we store and keep the transfer-oriented stuff in the
SessionHandle so that callbacks and callback data work fine even when
many easy handles share the same physical connection.
Previously, when we send all given buffer in data_source_callback, we
return NGHTTP2_ERR_DEFERRED, and nghttp2 library removes this stream
temporarily for writing. This itself is good. If this is the sole
stream in the session, nghttp2_session_want_write() returns zero,
which means that libcurl does not check writeability of the underlying
socket. This leads to very slow upload, because it seems curl only
upload 16k something per 1 second. To fix this, if we still have data
to send, call nghttp2_session_resume_data after nghttp2_session_send.
This makes nghttp2_session_want_write() returns nonzero (if connection
window still opens), and as a result, socket writeability is checked,
and upload speed becomes normal.
Stop curl from failing when non-fatal alert is received during
handshake. This e.g. fixes lots of problems when working with https
sites through proxies.
BoringSSL removed support for direct callers of SSL_CTX_callback_ctrl
and SSL_CTX_ctrl, so move to a way that should work on BoringSSL and

This commit requires nghttp2 v1.0.0 to compile, and migrate to v1.0.0,
and utilize recent version of nghttp2 to simplify the code,
First we use nghttp2_option_set_no_recv_client_magic function to
detect nghttp2 v1.0.0. That function only exists since v1.0.0.
Since nghttp2 v0.7.5, nghttp2 ensures header field ordering, and
validates received header field. If it found error, RST_STREAM with
PROTOCOL_ERROR is issued. Since we require v1.0.0, we can utilize
this feature to simplify libcurl code. This commit does this.
Migration from 0.7 series are done based on nghttp2 migration
document. For libcurl, we removed the code sending first 24 bytes
client magic. It is now done by nghttp2 library.

Also added some more info message for the connection re-use function to

Previously when we do pause because of out of buffer, we just throw
away unread data in connection buffer. This just broke protocol
framing, and I saw occasional FRAME_SIZE_ERROR. This commit fix this
issue by remembering how much data read, and in the next iteration, we
process remaining data.
This commit fixes the bug that streams get stuck if stream gets some
DATA, and stream->closed becomes true at the same time. Previously,
in this condition, after we processed DATA, we are going to try to
read data from underlying transport, but there is no data, and gets
EAGAIN. There was no code path to evaludate stream->closed.

lookup streams for incoming frames in the stream hash, hashing is based
on the stream id and we get the SessionHandle for the incoming stream
that way.
Previously we counted all connections to a specific host name and that
would be used for the CURLMOPT_MAX_HOST_CONNECTIONS check for example,
while servers on different port numbers are normally considered
different "origins" on the web and should thus be considered different
hosts.
All the existing Curl_bundle* functions were only ever used from within
the conncache.c file, so I moved them over and made them static (and
removed the Curl_ prefix).
This avoids unnecessary dynamic allocs and as this also removed the last
users of *hash_alloc() and *hash_destroy(), those two functions are now
removed.
The OpenSSL trace callback is wonderfully undocumented but given a
journey in the source code, it seems the cases were ssl_ver is zero
doesn't follow the same pattern and thus turned out confusing and
misleading. For now, we skip doing any CURLINFO_TEXT logging on those
but keep sending them as CURLINFO_SSL_DATA_OUT/IN.
Also, I added direction to the text info and I edited some functions
slightly.

The same logic is used in 'src/makefile.m32' when

The factor of 8 is a bytes-to-bits conversion factor, but pkt_size and
rate_bps are both in bytes. When using the rate limiting option, curl
waits 8 times too long, and then transfers very quickly until the
average rate reaches the limit. The average rate follows the limit over
time, but the actual traffic is bursty.

Previously in Curl_http2_switched, we called nghttp2_session_mem_recv to
parse incoming data which were already received while curl was handling

received SETTINGS from server at this point, so we missed opportunity to
send SETTINGS + ACK. This commit adds missing nghttp2_session_send call

It seems that some systems (e.g. fairly consistently in some recent
Solaris autobuilds) would manage to get to the connect phase before the
progress callback was called, resulting in a CURLE_COULDNT_CONNECT
error. Reworked the test to point at a test server that never returns a
full result so the progress callback always gets a chance to be called
before the transfer can complete in some other way.
The certificates were missing the digitalSignature and keyAgreement
usage types, of which at least digitalSignature was checked by CyaSSL.

- Get rid of this flood of warnings in Windows mingw build:
warning: missing terminating " character
The warning is due to the carriage return. When msysgit checks out files
from the repo by default it converts the line endings to CRLF. Prior to
this change when mkhelp.pl processed the MANUAL and curl.1 in CRLF
format the trailing carriage returns caused unnecessary CR in the
output.
Since we just started make use of free(NULL) in order to simplify code,
this change takes it a step further and:
- converts lots of Curl_safefree() calls to good old free()
- makes Curl_safefree() not check the pointer before free()
The (new) rule of thumb is: if you really want a function call that
frees a pointer and then assigns it to NULL, then use Curl_safefree().
But we will prefer just using free() from now on.
The following functions return immediately if a null pointer was passed.
* Curl_cookie_cleanup
* curl_formfree
It is therefore not needed that a function caller repeats a corresponding check.
This issue was fixed by using the software Coccinelle 1.0.0-rc24.

A signal handler for SIGALRM is installed in Curl_resolv_timeout. It is
configured to interrupt system calls and uses siglongjmp to return into
the function if alarm() goes off.
The signal handler is installed before curl_jmpenv is initialized.
This means that an already installed alarm timer could trigger the
newly installed signal handler, leading to undefined behavior when it
accesses the uninitialized curl_jmpenv.
Even if there is no previously installed alarm available, the code in
Curl_resolv_timeout itself installs an alarm before the environment is
fully set up. If the process is sent into suspend right after that, the
signal handler could be called too early as in previous scenario.
To fix this, the signal handler should only be installed and the alarm
timer only be set after sigsetjmp has been called.

Correctly check for memcmp() return value (it returns 0 if the strings match).
This is not really important, since curl is going to use http/1.1 anyway, but
it's still a bug I guess.
Set CMAKE_REQUIRED_DEFINITIONS to include definitions needed to get
the winsock2 API from windows.h. Simplify the order of checks to
avoid extra conditions.
Use check_include_file instead of check_include_file_concat to look
for OpenSSL headers. They do not need to participate in a sequence
of dependent system headers. Also they may cause winsock.h to be
included before ws2tcpip.h, causing the latter to not be detected
in the sequence.

Visual Studio 2005 and above defaults to disabling the startup banner
for the Compiler, Linker and MIDL tools (with /NOLOGO). As such there
is no need to explicitly set the SuppressStartupBanner directive, as
this is a leftover from the VC7 and VC7.1 projects being upgraded to
VC8 and above.
For consistency with other conditionally compiled code in openssl.c,
use OPENSSL_IS_BORINGSSL rather than HAVE_BORINGSSL and try to use
HAVE_BORINGSSL outside of openssl.c when the OpenSSL header files are
not included.
Previously we don't ignore PUSH_PROMISE header fields in on_header
callback. It makes header values mixed with following HEADERS,
resulting protocol error.
Prior to this change the options for exclusive SSL protocol versions did
not actually set the protocol exclusive.

... by removing generated files from the *_DIST variable [*] and instead

In preparation for adding the test suite and examples projects renamed
the top level "all" solution files to better describe what they are.
This will also enable us to use "curl" rather than "curlsrc" for the
command line tool solution and project files, which will simplify some

Defined the DEBUGBUILD pre-processor variable to allow extra logging,
which is particularly useful in debug builds, as we use this and Visual
Studio typically uses _DEBUG.
We could define DEBUBBUILD, in curl_setup.h, when _MSC_VER and _DEBUG is
defined but that would also affect the makefile based builds which we
probably don't want to do.
Modified the Curl_ossl_cert_status_request() function to return FALSE
when built with BoringSSL or when OpenSSL is missing the necessary TLS
extensions.
Commit 7a8b2885e2 made some functions static and removed the public
Curl_ prefix. Unfortunately, it also removed the sasl_ prefix, which
is the naming convention we use in this source file.

This error could also happen for non-SSPI builds when cryptography is
disabled (CURL_DISABLE_CRYPTO_AUTH is defined).
There is an issue with conflicting "struct timeval" definitions with
certain AmigaOS releases and C libraries, depending on what gets
included when. It's a minor difference - the OS one is unsigned,
whereas the common structure has signed elements. If the OS one ends up
getting defined, this causes a timing calculation error in curl.
It's easy enough to resolve this at the curl end, by casting the
potentially errorneous calculation to a signed long.

Also known as "status_request" or OCSP stapling, defined in RFC6066 section 8.
This requires GnuTLS 3.1.3 or higher to build, however it's recommended to use
at least GnuTLS 3.3.11 since previous versions had a bug that caused the OCSP
response verfication to fail even on valid responses.
This option can be used to enable/disable certificate status verification using
the "Certificate Status Request" TLS extension defined in RFC6066 section 8.
This also adds the CURLE_SSL_INVALIDCERTSTATUS error, to be used when the
certificate status verification fails, and the Curl_ssl_cert_status_request()

extension.

Some instances of the curlssl_close_all() function were declared with a
void return type whilst others as int. The schannel version returned
CURLE_NOT_BUILT_IN and others simply returned zero, but in all cases the
return code was ignored by the calling function Curl_ssl_close_all().
For the time being and to keep the internal API consistent, changed all
declarations to use a void return type.
To reduce code we might want to consider removing the unimplemented
versions and use a void #define like schannel does.
* Missing initialisation of upload status caused a seg fault
* Missing data termination caused corrupt data to be uploaded
* Data verification should be performed in <upload> element
* Added missing recipient list cleanup
For consistency, as we seem to have a bit of a mixed bag, changed all
instances of ipv4 and ipv6 in comments and documentations to use the
correct case.
Otherwise Curl_ssl_init_certinfo() can fail and set the num_of_certs
member variable to the requested count, which could then be used
incorrectly as libcurl closes down.
The return type for this function was 0 on success and 1 on error. This
was then examined by the calling functions and, in most cases, used to
return CURLE_OUT_OF_MEMORY.
Instead use CURLcode for the return type and return the out of memory
error directly, propagating it up the call stack.
Merge multiple internal arrays into one, even if some variables

A value of zero causes the thread to relinquish the remainder

ready to run. If there are no other threads of equal priority
ready to run, the function returns immediately, and the thread
continues execution.

The return type of this function is a boolean value, and even uses a
bool internally, so use bool in the function declaration as well as
the variables that store the return value, to avoid any confusion.

Removed the WIN64 pre-processor definition from the libcurl project
files as:
* WIN64 is not used in our source code
* The curl projects files don't define it
* It isn't required by or used in the platform SDK
* For backwards compatability curl_setup.h defines WIN32
* The compiler automatically defines _WIN64 for x64 builds
Historically Visual Studio projects have defined WIN32, in addition to
the compiler defined _WIN32 definition, and I had incorrectly changed
that to WIN64 for the x64 libcurl builds but not in the curl projects.
As such, it is questionable whether this should be defined or not. For
more information see the following cache of a discussion that took

There was a confusion between these: this commit tries to disambiguate them.
- Scope can be computed from the address itself.
- Scope id is scope dependent: it is currently defined as 1-based local
interface index for link-local scoped addresses, and as a site index(?) for
(obsolete) site-local addresses. Linux only supports it for link-local
addresses.
The URL parser properly parses a scope id as an interface index, but stores it
in a field named "scope": confusion. The field has been renamed into "scope_id".
Curl_if2ip() used the scope id as it was a scope. This caused failures
to bind to an interface.
Scope is now computed from the addresses and Curl_if2ip() matches them.
If redundantly specified in the URL, scope id is check for mismatch with
the interface index.
This commit should fix SF bug #1451.

By counting from 0 and up instead of backwards like before, we remove
the need for the "funny" check of the unsigned variable when decreased

The >= 0 is actually not required, since i underflows and
the for-loop is stopped using the < condition, but this
makes the VS2012 compiler and code analysis happy.

Previously USE_NTLM2SESSION would only be defined automatically when
USE_NTRESPONSES wasn't already defined. Separated the two definitions
so that the user can manually set USE_NTRESPONSES themselves but
USE_NTLM2SESSION is defined automatically if they don't define it.
As the OpenSSL and NSS Crypto engines are prefered by the core NTLM
routines, to the Windows Crypt API, don't define USE_WIN32_CRYPT
automatically when either OpenSSL or NSS are in use - doing so would
disable NTLM2Session responses in NTLM type-3 messages.
If the scratch buffer was allocated in a previous call to
Curl_smtp_escape_eob(), a new buffer not allocated in the subsequent
call and no action taken by that call, then an attempt would be made to
try and free the buffer which, by now, would be part of the data->state
structure.
This bug was introduced in commit 4bd860a001.
Fixed a problem with the CRLF. detection when multiple buffers were
used to upload an email to libcurl and the line ending character(s)
appeared at the end of each buffer. This meant any lines which started
with . would not be escaped into .. and could be interpreted as the end
of transmission string instead.
This only affected libcurl based applications that used a read function
and wasn't reproducible with the curl command-line tool.

The ability to do HTTP requests over a UNIX domain socket has been
requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a
discussion happened, no patch seems to get through. I decided to give it
a go since I need to test a nginx HTTP server which listens on a UNIX
domain socket.
One patch [3] seems to make it possible to use the
CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket.
Another person wrote a Go program which can do HTTP over a UNIX socket
for Docker[4] which uses a special URL scheme (though the name contains
cURL, it has no relation to the cURL library).
This patch considers support for UNIX domain sockets at the same level
as HTTP proxies / IPv6, it acts as an intermediate socket provider and
not as a separate protocol. Since this feature affects network
operations, a new feature flag was added ("unix-sockets") with a
corresponding CURL_VERSION_UNIX_SOCKETS macro.
A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This
option enables UNIX domain sockets support for all requests on the
handle (replacing IP sockets and skipping proxies).
A new configure option (--enable-unix-sockets) and CMake option
(ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I
deliberately did not mark this feature as advanced, this is a
feature/component that should easily be available.

Instead of depending the socket domain type on use_ipv6, specify the

If the scratch buffer already existed when the CRLF conversion was
performed then the buffer pointer would be checked twice for NULL. This
second check is only necessary if the call to malloc() was performed by
the first check.
Whilst I had moved the dot stuffing code from being performed before
CRLF conversion takes place to after it, in commit 4bd860a001, I had
moved it outside the 'when something read' block of code when meant
it could perform the dot stuffing twice on partial send if nread
happened to contain the right values. It also meant the function could
potentially read past the end of buffer. This was highlighted by the
following warning:

After commit 48d19acb7c the HTTP code would call Curl_nss_force_init()

This commit disables pipelining for HTTP/2 or upgraded connections. For
HTTP/2, we do not support multiplexing. In general, requests cannot be
pipelined in an upgraded connection, since it is now different protocol.

When the connection code decides to close a socket it informs the multi
system via the Curl_multi_closed function. The multi system may, in
turn, invoke the CURLMOPT_SOCKETFUNCTION function with
CURL_POLL_REMOVE. This happens after the socket has already been

Feature: http://sourceforge.net/p/curl/feature-requests/82/
Visual Studio 2012 introduced support for Windows Store apps as well as
supporting Windows Phone 8. Introduced build targets that allow more
modern APIs to be used as certain legacy ones are not available on these
new platforms.
Windows does not support using select() for sleeping without a dummy
socket. Instead use Windows' Sleep() and sleep for 100ms which is the
minimum suggested value in the curl_multi_fdset() doc.
Prior to this change the multi examples would exit prematurely since
select() would error instead of sleeping when called without an fd.

Although libcurl would never return CURL_VERSION_KERBEROS4 after 7.33,
so would not be output with --version, removed krb4 from the supported
features output.
Rather than define the function as extern in the source files that use
it, moved the function declaration into the SASL header file just like
the Digest and NTLM clean-up functions.
Additionally, added a function description comment block.
Revert commit 2257deb502 (Cmake: Avoid cycle directory dependencies,
2014-08-22) and add a comment explaining the purpose of the original
code.
The check_library_exists_concat macro is intended to be called multiple
times on a sequence of possibly dependent libraries. Later libraries
may depend on earlier libraries when they are static. They cannot be
safely linked in reverse order on some platforms.

Revert commit 1269df2e3b (Cmake: Don't check for all headers each
time, 2014-08-15) and add a comment explaining the purpose of the
original code.
The check_include_file_concat macro is intended to be called multiple
times on a sequence of possibly dependent headers. Later headers
may depend on earlier headers to provide declarations. They cannot
be safely included independently on some platforms.
For example, many POSIX APIs document including sys/types.h before some
other headers. Also on some OS X versions sys/socket.h must be included
before net/if.h or the check for the latter will fail.

This is the only user of the backtick operator in the command. As the
commands will soon not be executed by a shell anymore (but by perl),
replace the command with its output.

Previously if HTTP/2 traffic is appended to HTTP Upgrade response header
(thus they are in the same buffer), the trailing HTTP/2 traffic is not
processed and lost. The appended data is most likely SETTINGS frame.
If it is lost, nghttp2 library complains server does not obey the HTTP/2
protocol and issues GOAWAY frame and curl eventually drops connection.
This commit fixes this problem and now trailing data is processed.
Commit fe0f8967bf fixed a problem with krb5 not being defined as a
supported feature when HAVE_GSSAPI is defined, however, it should
only be included if CURL_DISABLE_CRYPTO_AUTH is not set, like when
SPNEGO is listed as a feature.
Makes test1119 pass when building with cmake.
configurehelp.pm is generated by configure (autotools). As cmake does
not provide a separate variable for the C preprocessor, default to cpp.
Before commit ef24ecde68 ("symbol-scan:
use configure script knowledge about how to run the C preprocessor"),
this tool would also use 'cpp'.

Fix detection of the AsynchDNS feature which not just depends on
pthreads support, but also on whether USE_POSIX_THREADS is set or not.
Caught by test 1014.
This patch adds a new ENABLE_THREADED_RESOLVER option (corresponding to
--enable-threaded-resolver of autotools) which also needs a check for
HAVE_PTHREAD_H.
For symmetry with autotools, CURL_USE_ARES is renamed to ENABLE_ARES
(--enable-ares). Checks that test for the availability actually use
USE_ARES instead as that is the result of whether a-res is available or
not (in practice this does not matter as CARES is marked as required
package, but nevertheless it is better to write the intent).

Otherwise Curl_gethostname always fails. Windows has gethostname
since Vista according to
http://msdn.microsoft.com/en-us/library/ms738527%28VS.85%29.aspx, but
accordings to byte_bucket's VC 2005 documentation, it is available even
in Windows 95. (possibly after installing a Platform SDK, the
Windows Server 2003 SP1 Platform SDK should be sufficient).

I noticed that a patched cmake build would pass tests with a fake local
hostname, but the autotools build skips them:
got unexpected host name back, LD_PRELOAD failed
It turns out that -fvisibility=hidden hides the symbol, and since the
tests are not part of libcurl, it fails too. Just remove the LIBCURL
guard.
Broken since cURL 7.30 (commit 83a42ee20e,
"curl.h: stricter CURL_EXTERN linkage decorations logic").

In preparation for moving the NTLM message code into the SASL module,
and separating the native code from the SSPI code, added functions that
simply call the functions in curl_ntlm_msg.c.
Reworked the two sections that discuss modifying the Visual Studio pre-
processor settings, and vc6libcurl.dsw/vc6libcurl.dsp, to remove the
project files references as they have been superseded by a more thorough
set of project files for VC6 through VC12, but to also give the correct
reference to this setting in later versions of Visual Studio.
USE_NTLM would only be defined if: HTTP support was enabled, NTLM and
cryptography weren't disabled, and either a supporting cryptography
library or Windows SSPI was being compiled against.
This means it was not possible to build libcurl without HTTP support
and use NTLM for other protocols such as IMAP, POP3 and SMTP. Rather
than introduce a new SASL pre-processor definition, removed the HTTP
prerequisite just like USE_SPNEGO and USE_KRB5.
Note: Winbind support still needs to be dependent on CURL_DISABLE_HTTP
as it is only available to HTTP at present.
This bug dates back to August 2011 when I started to add support for
NTLM to SMTP.
As the list has gotten a little messy and hard to read, especially with
the introduction of deprecated items, aligned the values and comments
into clean columns and reworked some of the comments in the process.
Added !SSPI to the features list of the HTTP digest tests, as SSPI
based builds now use the Windows SSPI messaging API rather than the
internal functions, and we can't control the random numbers that get
used as part of the digest.
Reworked the input token (challenge message) storage as what is passed
to the buf and desc in the response generation are typically blobs of
data rather than strings, so this is more in keeping with other areas
of the SSPI code, such as the NTLM message functions.
This temporarily breaks HTTP digest authentication in SSPI based builds,
causing CURLE_NOT_BUILT_IN to be returned. A follow up commit will
resume normal operation.
This is very handy when updating the RELEASE-NOTES as then we sometimes
have names added manually in the existing list and we use this script to
update the set.
As the curl command-line tool now includes it's own version of strdup(),
for platforms that don't have it, fixed up the git respository Visual
Studio project file generator to not include the version from lib in the
tool project files, rather than having both lib\strdup.[c|h] and
src\tool_strdup.[c|h] present.
Added forward declaration of digestdata to overcome the following
compilation warning:
warning: 'struct digestdata' declared inside parameter list
Additionally made the ntlmdata forward declaration dependent on
USE_NTLM similar to how digestdata and kerberosdata are.
To provide consistent behaviour between the various HTTP authentication
functions use CURLcode based error codes for Curl_input_digest()
especially as the calling code doesn't use the specific error code just
that it failed.
docs/THANKS-filter is a new filter file for converting contributor names
we get or have recorded in alternative formats to the one we already use
in THANKS. To help us show individual contributors using a single
presentation of their names.
The removed names also appear as:
Andrés García, François Charlier, Gökhan Şengün, Michał Górny, Sébastien
Willemijns, Christopher Conroy, John E. Malmberg, Luca Altea, Peter Su,
S. Moonesamy, Samuel Listopad, Yasuharu Yamada, Karl Moerder
These were previously hard coded, and whilst defined in security.h,
they may or may not be present in old header files given that these
defines were never used in the original code.
Not only that, but there appears to be some ambiguity between the ANSI
and UNICODE NTLM definition name in security.h.
