It is now possible to use any combination of features without
having to 1st add makefile targets to the main makefile. The
main makefile now passes the 'mingw32-feat1-feat2' as var CFG,

the features to be enabled.
changed windows.h include to system header;
changed obsolete 2nd check for str_w to str_utf8 in order to catch
malloc() failure and avoid a free(NULL);

Added CURLOPT_TRANSFER_ENCODING as the option to set to request Transfer
Encoding in HTTP requests (if built zlib enabled). I also renamed
CURLOPT_ENCODING to CURLOPT_ACCEPT_ENCODING (while keeping the old name
around) to reduce the confusion when we have to encoding options for
HTTP.
--tr-encoding is now the new command line option for curl to request
this, and thus I updated the test cases accordingly.
When TE: is inserted in the request, we must add a "Connection: TE" as
well to be HTTP 1.1 compliant. If a custom Connection: header is passed
in, we must use that and only append TE to it. Test case 1125 verifies
TE: + custom Connection:.
Since this struct member is used in the code to determine what and how
to decode automatically and since it is now also used for compressed
Transfer-Encodings, I renamed it to the more suitable 'auto_decoding'
Transfer-Encoding differs from Content-Encoding in a few subtle ways,
but primarily it concerns the transfer only and not the content so when
discovered to be compressed we know we have to uncompress it. There will
only arrive compressed transfers in a response after we have requested
them with the appropriate TE: header.
Test case 1122 and 1123 verify.
When checking if an existing RTSP connection is alive or not, the

Stop the abuse of CURLE_FAILED_INIT as return code for things not being
init related by introducing two new return codes:
CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION
CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for
several years. It is used for returning error when something is
attempted to be used but the feature/option was not enabled or
explictitly disabled at build-time. Getting this error mostly means that
libcurl needs to be rebuilt.
CURLE_FAILED_INIT is now saved and used strictly for init
failures. Getting this problem means something went seriously wrong,
like a resource shortage or similar.
CURLE_UNKNOWN_OPTION is the option formerly known as
CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present,
separately defined to be removed in a very distant future). This error
code is meant to be used to return when an option is given to libcurl
that isn't known. This problem would mostly indicate a problem in the
program that uses libcurl.
In my attempts to reduce #ifdefs in code, the SOCKS functions are now
macros when libcurl is built without proxy support and therefore the FTP
code could avoid some #ifs.
The new http_proxy.* files now host HTTP proxy specific code (500+ lines
moved out from http.c), and as a consequence there is a macro introduced
for the Curl_proxyCONNECT() function so that code can use it without
actually supporting proxy (or HTTP) in builds.
1 - make sure to #define macros for cookie functions in the cookie
header when cookies are disabled to avoid having to use #ifdefs in code
using those functions.
2 - move cookie-specific code to cookie.c and use the functio

net result: 6 #if lines removed, and 9 lines of code less

When asked to bind the local end of a connection when doing a request,
the code will now disqualify other existing connections from re-use even
if they are connected to the correct remote host.
This will also affect which connections that can be used for pipelining,
so that only connections that aren't bound or bound to the same
device/port you're asking for will be considered.
The RTSP-specific function for checking for "dead" connection is better
located in rtsp.c. The code using this is now written without #ifdefs as
the function call is instead turned into a macro (in rtsp.h) when RTSP
is disabled.
Move ipv6-functional-probe into a single function that is used from all

When libcurl sends a HTTP request on a re-used connection and detects it

CURLOPT_SSL_VERIFYPEER equal to zero, NSS remembered that the peer

connecting to the same server with CURLOPT_SSL_VERIFYPEER equal to one.
This patch turns off the SSL session cache for the particular SSL socket
if peer verification is disabled. In order to avoid any performance
impact, the peer verification is completely skipped in that case, which
makes it even faster than before.
Bug: https://bugzilla.redhat.com/678580
The PROT_* set of internal defines for the protocols is no longer
used. We now use the same bits internally as we have defined in the
public header using the CURLPROTO_ prefix. This is for simplicity and
because the PROT_* prefix was already used duplicated internally for a
set of KRB4 values.
The PROTOPT_* defines were moved up to just below the struct definition
within which they are used.
The protocol handler struct got a 'flags' field for special information
and characteristics of the given protocol.
This now enables us to move away central protocol information such as
CLOSEACTION and DUALCHANNEL from single defines in a central place, out
to each protocol's definition. It also made us stop abusing the protocol
field for other info than the protocol, and we could start cleaning up
other protocol-specific things by adding flags bits to set in the
handler struct.
The "protocol" field connectdata struct was removed as well and the code
now refers directly to the conn->handler->protocol field instead. To
make things work properly, the code now always store a conn->given
pointer that points out the original handler struct so that the code can
learn details from the original protocol even if conn->handler is
modified along the way - for example when switching to go over a HTTP
proxy.
The non-blocking connect improvement for IMAP showed that we didn't

Some protocols have to call the underlying functions without regard to
what exact state the socket signals. For example even if the socket says
"readable", the send function might need to be called while uploading,
or vice versa. This is the case for libssh2 based protocols: SCP and
SFTP and we now introduce a define to set those protocols and we make
the multi interface code aware of this concept.
This is another fix to make test 582 run properly.
As a new state recently was added to the IMAP state machine it has to be
in the array of names as well as otherwise libcurl crashes when a debug
version runs...
For uploads we want to use the _sending_ function even when the socket
turns out readable as the underlying libssh2 sftp send function will
deal with both accordingly. This is what the cselect_bits magic is for.
Fixes test 582.

Both SFTP and SCP are protocols that need to shut down stuff properly
when the connection is about to get torned down. The primary effect of
not doing this shows up as memory leaks (when using SCP or SFTP with the
multi interface).
This is one of the problems detected by test 582.
As we know how much to send, we can and should stop once we've sent that
much data as it avoids having to rely on other mechanisms to detect the
end.
This is one of the problems detected by test 582.

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

the ball rolling.

Removed the debug code from Curl_parsenetrc as it is superseeded by

After a request times out, the connection wasn't properly closed and
prevented to get re-used, so subsequent transfers could still mistakenly
get to use the previously aborted connection.
When failing to connect the protocol during the CURLM_STATE_PROTOCONNECT
state, Curl_done() has to be called with the premature flag set TRUE as
for the pingpong protocols this can be important.
When Curl_done() is called with premature == TRUE, it needs to call
Curl_disconnect() with its 'dead_connection' argument set to TRUE as
well so that any protocol handler's disconnect function won't attempt to
use the (control) connection for anything.
This problem caused the pingpong protocols to fail to disconnect when
STARTTLS failed.

Introducing a few CURL_SOCKOPT* defines for conveniance. The new
CURL_SOCKOPT_ALREADY_CONNECTED signals to libcurl that the socket is to
be treated as already connected and thus it will skip the connect()
call.
It turns out some systems rely on the gmtime or gmtime_r to be defined
already in the system headers and thus my "precaution" redefining of
them only caused trouble. They are now removed.
On second thought, I think CURLE_TLSAUTH_FAILED should be eliminated. It
was only being raised when an internal error occurred while allocating
or setting the GnuTLS SRP client credentials struct. For TLS
authentication failures, the general CURLE_SSL_CONNECT_ERROR seems
appropriate; its error string already includes "passwords" as a possible
cause. Having a separate TLS auth error code might also cause people to
think that a TLS auth failure means the wrong username or password was
entered, when it could also be a sign of a man-in-the-middle attack.
When the callback returns an error, this function must make sure to return
CURLE_ABORTED_BY_CALLBACK properly and not CURLE_OK as before to allow the
callback to properly abort the operation.
The main has not been updated from some time and is out of sync with
the code. The code is now tested by several test cases so no need for
a seperate code path.
Instead of polluting many places with #ifdefs, we create a single place
for this function, and also check return code properly so that a NULL
pointer returned won't cause problems.
