This workaround fixes an issue on MinGW/Msys regarding the Perl
testsuite scripts not being able to signal or control the server
processes. The MinGW Perl runtime only sees the Msys processes and
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 new read and write wrapper functions support reading from stdin
and writing to stdout/stderr on Windows by using the appropriate
Windows API functions and data types.
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.

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.
These verfy that the 'memory tracking' subsystem is actually doing its
job when using curl tool (#96), a test in libtest (#558) and also a unit
test (#1330), in order to prevent regressions in this functionallity.
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.

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.
Any IMAP parameter can come in escaped and in double quotes. Added a

* Added support for STORE - Returns hardcoded updated flags
* Changed handling of SELECT - Returns much more information in the

in the IMAP RFC
* Changed handling of FETCH - Fixed response format
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.
Follow up fix to commit 62bd217464 to cater for servers that don't
respond with a 250 in their EHLO responses. Additionally updated the
SMTP tests to respond with a 250 response code as per RFC5321.
This bug report properly identified that when doing SMTP and aborting
the transfer with a callback, it must be considered aborted prematurely
by the code to avoid QUIT etc to be attempted as that would cause a
hang.
The new test case 1507 verifies this behavior.

Updated the automatic response tag generation to follow the examples
given in RC3501, which list a 4 character string such as A001, A002,

As a unique identifier should be generated for each command the string
generation is based on the connection id and the incrementing command
id.
When a connection is no longer used, it is kept in the cache. If the
cache is full, the oldest idle connection is closed. If no connection is
idle, the current one is closed instead.

Automake documents that doing this will make it choose a different name
for intermediate object files even when sharing source files across
targets of same Makefile.am.
Up to automake 1.13.1 target's intermediate object files were placed
in the build subdirectory of the target. We depended on this, probably
undocumented behavior, to achieve same behavior as if a per-target flag
had been specified when building targets that actually belong to
different Makefile.am files.
It seems automake 1.13.2 is going to break behavior mentioned above.
So, lets use a documented behavior in order to achieve same purpose,
across automake versions, no matter where automake wishes to place
intermediate object files.
Our build targets that already were using a per-target '_CFLAGS' or
'_CPPFLAGS' need no 'fixing', these were already 'fixed'. The only
Makefile.am or Makefile.in files in libcurl's source tree touched by
this 'fix' are tests/libtest/Makefile.inc and tests/unit/Makefile.inc.
This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.
Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]
Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]
----------------------------------------
1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.
Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h
The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.
Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.
All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.
This commit fixes support for sockets that are ready to accept

lib/objnames.inc provides definition of curl_10char_object_name() shell

Test case 1221 does unit testng of this function and also verifies

runtests.pl -am now uses the "PASS/FAIL: [desc]" output for each
executed test. You can run 'make test-am' in the root build directory to
invoke that. The reason for this output style is to better allow generic
test suite parsers to also grok our test output.
The test Makefile now also tests that perl was indeed found and that the
PERL variable points to an executable before it tries to run the main
test perl script runtests.pl,
It makes no difference from curl's point of view but
makes it more convenient to use the tests with a
lws-normalizing proxy between curl and the test server.
Consistently use CRLF instead. The mixed endings weren't

This change doesn't matter for curl itself but makes using

If we use memory functions (malloc, free, strdup etc) in C sources in

After Ajit's report of a failure in the first category in http_proxy.c,
I spotted a few in the second category as well. These problems are now

As pointed out in Bug report #3579064, curl_multi_perform() would
wrongly use a blocking mechanism internally for some commands which

The test would hang and get aborted with a "ABORTING TEST, since it
seems that it would have run forever." until I prevented that from
happening.
I also fixed the data file which got broken CRLF line endings when I
sucked down the path from Joe's repo == my fault.
Removed #37 from KNOWN_BUGS as this fix and test case verifies exactly
this.
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.

Fix a bug where closed sockets (fd -1) were left in the all_sockets
list, because of missing parens in a pointer arithmetic expression
Reenable the tests that were locking up due to this bug.
SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value
of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they
won't continue reading until after poll is called again.
for non-blocking sockets: now -1 means error or connection finished, 1 means data was read, and 0
means there is no data available now so need to wait for poll (new return value)
half-finished.
Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we
initialize it from the caller we must be careful not to overwrite the pipeline data.
Also we now need to handle the case where the buffer is already full when get_request is called -
previously this never happened as it was always called with an empty buffer and looped until done.
Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll
signals it is readable.
Replaced the Windows real path from mount hack with a more
reliable and simpler hack: the MSYS shell has a builtin pwd
which understands a -W option which does convertion to Windows
paths. Tested and confirmed that this works on all MSYS versions
I have back to a 3 year old one.
I made "connmon" not get initialized properly before use, and I use the
big hammer and make sure we always clear the entire struct to avoid any
problem like this in the future.
Two commits ago, we fixed a bug where the connction would be closed
prematurely after a HEAD. Now I added connection-monitor to test 48 and
added a second HEAD and make sure that both are sent over the same
connection.
This triggered a failure before the bug fix and now works. Will help us
avoid a future regression of this kind.
This makes verifying easier and makes us more sure curl closes the
connection only at the correct point in time. Adjusted test 206 and 1008
accordingly and updated the docs for it.
Since the order of the cookies is sorted by the length of the paths,
having them on the same path length will make the test depend on what
order the qsort() implementation will put them. As seen in the
windows/msys output posted by Guenter in this posting:
http://curl.haxx.se/mail/lib-2012-07/0105.html
Test 1008 and 206 don't show the disconnect since it happens when SWS
awaits a new request, but 503 does and so the verify section needs that
string added.
I moved out the servercmd parsing into a its own function called
parse_servercmd() and made sure it gets used also when the test number
is extracted from CONNECT requests. It turned out sws didn't do that
previously!
Using this, the server will output in the protocol log when the
connection gets disconnected and thus we will verify correctly in the
test cases that the connection doesn't get closed prematurely. This is
important for example NTLM to work.
Documentation added to FILEFORMAT, test 503 updated to use this.
With this commit, checks done in previous test2017 are now done in test2018.
Whole range test2017 to test2022 DISABLED until configure is capable of

Print "parsing (...) OK" only when no warnings are generated. If
no file is found in Metalink, treat it FAILED.
If no digest is provided, print WARNING in parse_metalink().
Also print validating FAILED after download.
These changes make tests 2012 to 2016 pass.
Test definition section parts which needed to include xml-lingo as contents
of that part required that the xml-blurb was written as a single line. Now the
xml-data inside the part can be written multiline making it more readable.
Tested with <client><file> part which is written to disk before <command> runs.
Verify that the "Saved to filename 'blabla'" message is only displayed when
the 'blabla' filename being used _actually_ has been specified by the server
in the Content-Disposition header.
Use relative path for unintended file creation postcheck.
When a <file> part is now specified with no contents at all, this
will actually verify that the specified file has no contents at all.
Previously file contents would be ignored.
This is done introducing tags <file1> to <file4> besides existing <file> one,
as well as corresponding <stripfile1> to <stripfile4> ones, that can be used
in the <verify> section in the same way as the non-numbered ones.
Introduce SUPPORTCAPA and SUPPORTAUTH config commands to allow further
pop3 test server expansion for tests that require CAPA or AUTH support,
although this will need some extra work to make it fully functional.
Added support for detecting the supported SASL authentication mechanisms
via the AUTH command. There are two ways of detecting them, either by
using the AUTH command, that will return -ERR if not supported or by
using the CAPA command which will return SASL and the list of mechanisms
if supported, not include SASL if SASL authentication is not supported
or -ERR if the CAPA command is not supported. As such it seems simpler
to use the AUTH command and fallback to normal clear text authentication
if the the command is not supported.
Additionally updated the test cases to return -ERR when the AUTH command
is encountered. Additional test cases will be added when support for the
individual authentication mechanisms is added.
To achieve this, first new structure HeaderData is defined to hold
necessary data to perform header-related work. Then tool_header_cb now
receives HeaderData pointer as userdata. All header-related work
(currently, dumping header and Content-Disposition inspection) are done
in this callback function. HeaderData.outs->config is used to determine
whether each work is done.
Unit tests were also updated because after this change, curl code always
sets CURLOPT_HEADERFUNCTION and CURLOPT_HEADERDATA.
Tested with -O -J -D, -O -J -i and -O -J -D -i and all worked fine.
When doing a chunked-encoded POST with -d (CURLOPT_POSTFIELDS) and the
size of the POST was zero length, it made libcurl first send a zero

should rather just send the terminating chunk as it does with this fix.
Test case 1333 is added to verify.

I spotted this problem when doing test runs with PolarSSL builds.
With FOLLOWLOCATION enabled. When a 3xx page is downloaded and the
download size was known (like with a Content-Length header), but the
subsequent URL (transfered after the 3xx page) was chunked encoded, then
the previous "known download size" would linger and cause the progress
meter to get incorrect information, ie the former value would remain
being sent in. This could easily result in downloads that were WAY
larger than "expected" and would cause >100% outputs with the curl
command line tool.
Test case 599 was created and it was used to repeat the bug and then
verify the fix.

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

the desired casing.
