76 private header files renamed to use our standard naming scheme.
This change affects 322 files in libcurl's source tree.

Inclusion of top two most included header files now done in setup_once.h

A bundle is a list of all persistent connections to the same host.
The connection cache consists of a hash of bundles, with the
hostname as the key.
The benefits may not be obvious, but they are two:
1) Faster search for connections to reuse, since the hash
lookup only finds connections to the host in question.
2) It lays out the groundworks for an upcoming patch,
which will introduce multiple HTTP pipelines.
This patch also removes the awkward list of "closure handles",
which were needed to send QUIT commands to the FTP server
when closing a connection.
Now we allocate a separate closure handle and use that
one to close all connections.
This has been tested in a live system for a few weeks, and of
course passes the test suite.

The existing logic only cut off the fragment from the separate 'path'
buffer which is used when sending HTTP to hosts. The buffer that held
the full URL used for proxies were not dealt with. It is now.
Test case 5 was updated to use a fragment on a URL over a proxy.

After a research team wrote a document[1] that found several live source
codes out there in the wild that misused the CURLOPT_SSL_VERIFYHOST
option thinking it was a boolean, this change now bans 1 as a value and
will make libcurl return error for it.
1 was never a sensible value to use in production but was introduced
back in the days to help debugging. It was always documented clearly
this way.
1 was never supported by all SSL backends in libcurl, so this cleanup
makes the treatment of it unified.
The report's list of mistakes for this option were all PHP code and
while there's a binding layer between libcurl and PHP, the PHP team has
decided that they have an as thin layer as possible on top of libcurl so
they will not alter or specifically filter a 'TRUE' value for this
particular option. I sympathize with that position.

When given a string as 'srp' it didn't work, but required 'SRP'.
Starting now, the check disregards casing.

Selected socks proxy in Google's Chrome browser. Resulting in the
following environment variables:
NO_PROXY=localhost,127.0.0.0/8
ALL_PROXY=socks://localhost:1080/
all_proxy=socks://localhost:1080/
no_proxy=localhost,127.0.0.0/8
... and libcurl didn't treat 'socks://' as socks but instead picked HTTP
proxy.

If we need an NTLM connection and one already exists, always choose that
one.

I suspect this is a regression introduced in commit 207cf150, included
since 7.24.0.
Avoid showing '(nil)' as hostname in verbose output by making sure the
hostname fixup function is called early enough to set the pointers that
are used for this. The name data is set again for each request even for
re-used connections to handle multiple hostnames over the same
connection (like with proxy) or that the casing etc of the host name is
changed between requests (which has proven to be important at least once
in the past).
Test1011 was modified to use a redirect with a re-used a connection
since it then showed the bug and now lo longer does. There's currently
no easy way to have the test suite detect 'nil' texts in verbose ouputs
so no tests will detect if this problem gets reintroduced.

Ensure that the copy of the CURLOPT_INTERFACE string is freed if we

Since Curl_pgrsDone() itself calls Curl_pgrsUpdate() which may return an
abort instruction or similar we need to return that info back and
subsequently properly handle return codes from Curl_pgrsDone() where
used.

Roman Mamedov spotted (in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=670126) that curl would
not complain when given a URL with an IPv6 numerical address without
brackets. It would simply cut off the last ":[hex]" part and thus not
work correctly.
That's a URL using an illegal syntax and now libcurl will instead return
a clear error code and error message detailing the error.
The above mentioned bug report claims this to be a regression but
libcurl does not guarantee functionality when given URLs that aren't
following the URL spec (RFC3986 mostly). I consider the fact that it
used to handle this differently a mere coincidence.

Fail with CURLE_NOT_BUILT_IN when none of requested auth methods is supported.
Reject CURLAUTH_ONLY bit when given alone or with CURLAUTH_NONE.
|

Data type of internal vars holding CURLAUTH_* bitmasks changed from 'long' to
'unsigned long' for proper handling and operating.

As it turns out, some people do want that after all.

The refactoring of HTTP CONNECT handling in commit 41b0237834232 that
made it protocol independent broke it for the multi interface. This fix
now introduce a better state handling and moved some logic to the

Curl_protocol_connect() now does the tunneling through the HTTP proxy if
requested instead of letting each protocol specific connection function
do it.

Added a new CURLOPT_MAIL_AUTH option that allows the calling program to
set the optional AUTH parameter in the MAIL FROM command.
When this option is specified and an authentication mechanism is used
to communicate with the mail server then the AUTH parameter will be
included in the MAIL FROM command. This is particularly useful when the
calling program is acting as a relay in a trusted environment and
performing server to server communication, as it allows the relaying
server to specify the address of the mailbox that was used to
authenticate and send the original email.

... by making sure that the string is always freed after the invoke as
parse_proxy will always copy the data and this way there's a single
free() instead of multiple ones.
|
|
The proxy parser function strips off trailing slashes off the proxy name
which could lead to a mistaken zero length proxy name which would be
treated as no proxy at all by subsequent functions!
This is now detected and an error is returned. Verified by the new test
1329.

Allow an appliction to set libcurl specific SSL options. The first and
only options supported right now is CURLSSLOPT_ALLOW_BEAST.
It will make libcurl to disable any work-arounds the underlying SSL
library may have to address a known security flaw in the SSL3 and TLS1.0
protocol versions.
This is a reaction to us unconditionally removing that behavior after
this security advisory:
http://curl.haxx.se/docs/adv_20120124B.html
... it did however cause a lot of programs to fail because of old
servers not liking this work-around. Now programs can opt to decrease
the security in order to interoperate with old servers better.

This adds three new options to control the behavior of TCP keepalives:
- CURLOPT_TCP_KEEPALIVE: enable/disable probes
- CURLOPT_TCP_KEEPIDLE: idle time before sending first probe
- CURLOPT_TCP_KEEPINTVL: delay between successive probes
While not all operating systems support the TCP_KEEPIDLE and
TCP_KEEPINTVL knobs, the library will still allow these options to be
set by clients, silently ignoring the values.

When a HTTP connection is re-used for a subsequent request without
proxy, it would always re-use the Host: header of the first request. As
host names are case insensitive it would make curl send another host
name case that what the particular request used.
Now it will instead always use the most recent host name to always use
the desired casing.
Added test case 1318 to verify.

Backpedaled out the funny double-change of state in the multi state
machine by adding a new argument to the do_more() function to signal
completion. This way it can remain in the DO_MORE state properly until
done. Long term, the entire DO_MORE logic should be moved into the FTP
code and be hidden from the multi code as the logic is only used for
FTP.

1- Two new error codes are introduced.
CURLE_FTP_ACCEPT_FAILED to be set whenever ACCEPTing fails because of
FTP server connected.
CURLE_FTP_ACCEPT_TIMEOUT to be set whenever ACCEPTing timeouts.
Neither of these errors are considered fatal and control connection
remains OK because it could just be a firewall blocking server to
connect to the client.
2- One new setopt option was introduced.
CURLOPT_ACCEPTTIMEOUT_MS
It sets the maximum amount of time FTP client is going to wait for a
server to connect. Internal default accept timeout is 60 seconds.

Regression introduced in 7.23.0 with commit 9dd85bce. The function in
which the PRETRANSFER time stamp was recorded was moved in time causing
it be stored very quickly after the start timestamp. On most systems
shorter than 1 millisecond and thus it wouldn't even show with -w
"%{time_pretransfer}" using the command line tool.

This is a regression since who knows when. When spotting that a HTTP
proxy is used we must not uncondititionally enable the HTTP protocol
since if we do tunneling through the proxy we're still using the target
protocol.

By setting PROTOPT_NOURLQUERY in the protocol handler struct, the
protocol will get the "query part" of the URL cut off before the data is
handled by the protocol-specific code. This makes libcurl adhere to
RFC3986 section 2.2.
Test 1220 is added to verify a file:// URL with query-part.

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

After a PORT has been issued, and the multi handle would switch to the
CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would
return the wrong fdset to wait for when curl_multi_fdset() is
called. The code would blindly assume that it was waiting for a connect
of the second connection, while that isn't true immediately after the
PORT command.
Also, the function multi.c:domore_getsock() was highly FTP-centric and
therefore ugly to keep in protocol-agnostic code. I solved this problem
by introducing a new function pointer in the Curl_handler struct called
domore_getsock() which is only called during the DOMORE state for
protocols that set that pointer.
The new ftp.c:ftp_domore_getsock() function now returns fdset info about
the control connection's command/response handling while such a state is
in use, and goes over to waiting for a writable second connection first
once the commands are done.
The original problem could be seen by running test 525 and checking the
time stamps in the FTP server log. I can verify that this fix at least
fixes this problem.
