2014-12-27code/docs: Use correct case for IPv4 and IPv6Steve Holme
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.
2014-12-26code/docs: Use Unix rather than UNIX to avoid use of the trademarkSteve Holme
Use Unix when generically writing about Unix based systems as UNIX is the trademark and should only be used in a particular product's name.
2014-12-26sockfilt.c: Reduce the number of individual memory allocationsMarc Hoersken
Merge multiple internal arrays into one, even if some variables will not not be used. They are all created with the number of file descriptors as their size. Also fix possible thread handle leak in CloseHandle-loop.
2014-12-26sockfilt.c: Replace 100ms sleep with thread throttleMarc Hoersken
Improves performance of test cases 574 and 575 by 50%. A value of zero causes the thread to relinquish the remainder of its time slice to any other thread of equal priority that is ready to run. If there are no other threads of equal priority ready to run, the function returns immediately, and the thread continues execution. http://msdn.microsoft.com/library/windows/desktop/ms686307.aspx
2014-12-21sockfilt.c: use non-Ex functions that are available before WinXPMarc Hoersken
It was initially reported by Guenter that GetFileSizeEx requires (_WIN32_WINNT >= 0x0500) to be true.

2014-12-04libcurl: add UNIX domain sockets supportPeter Wu
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.

2014-12-04sws: try to remove socket and retry bindPeter Wu
If sws is killed it might leave a stale socket file on the filesystem which would cause an EADDRINUSE error. After this patch, it is checked whether the socket is really stale and if so, the socket file gets removed and another bind is executed. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
2014-12-04sws: add UNIX domain socket supportPeter Wu
This extends sws with a --unix-socket option which causes the port to be ignored (as the server now listens on the path specified by --unix-socket). This feature will be available in the following patch that enables checking for UNIX domain socket support. Proxy support (CONNECT) is not considered nor tested. It does not make sense anyway, first connecting through a TCP proxy, then let that TCP proxy connect to a UNIX socket. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
2014-12-04sws: restrict TCP_NODELAY to IP socketsPeter Wu
TCP_NODELAY does not make sense for Unix sockets, so enable it only if the socket is using IP. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
2014-12-03sws.c: Fixed compilation warning when IPv6 is disabledSteve Holme
sws.c:69: warning: comma at end of enumerator list
2014-11-30sws: move away from IPv4/IPv4-only assumptionPeter Wu
Instead of depending the socket domain type on use_ipv6, specify the domain type (AF_INET / AF_INET6) as variable. An enum is used here with switch to avoid compiler warnings in connect_to, complaining that rc is possibly undefined (which is not possible as socket_domain is always set). Besides abstracting the socket type, make the debugging messages be independent on IP (introduce location_str which points to "port XXXXX"). Rename "ipv_inuse" to "socket_type" and tighten the scope (main). Signed-off-by: Peter Wu <peter@lekensteyn.nl>

2014-11-10cmake: add ENABLE_THREADED_RESOLVER, rename ARESPeter Wu
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).

2014-10-09Cmake: Got rid of setup_curl_dependenciesJakub Zakrzewski
There is no need for such function. Include_directories propagate by themselves and having a function with one simple link statement makes little sense.
2014-05-29tests: Fix portability issue with the tftpd server and timeoutsDan Fandrich
gcc spit out warning: variable 'x' might be clobbered by 'longjmp' or 'vfork' messages for a few variables. These automatic variables were expected to be changed between a setjmp/longjmp and hold their values, so are now marked volatile.

2014-01-26sockfilt.c: fixed and simplified Windows select functionMarc Hoersken
Since the previous complex select function with initial support for non-socket file descriptors, did not actually work correctly for Console handles, this change simplifies the whole procedure by using an internal waiting thread for the stdin console handle. The previous implementation made it continuously trigger for the stdin handle if it was being redirected to a parent process instead of an actual Console input window. This approach supports actual Console input handles as well as anonymous Pipe handles which are used during input redirection. It depends on the fact that ReadFile supports trying to read zero bytes which makes it wait for the handle to become ready for reading.

2013-07-19WIN32 MemoryTracking: require UNICODE for wide strdup code supportYang Tse
2013-07-18Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage".Yang Tse
This reverts commit 7ed25cc, reinstating commit 8ec2cb5. As of 18-jul-2013 we still do have code in libcurl that makes use of these memory functions. Commit 8ec2cb5 comment still applies and is yet valid. These memory functions are solely used in Windows builds, so all related code is protected with '#ifdef WIN32' preprocessor conditional compilation directives. Specifically, wcsdup() _wcsdup() are used when building a Windows target with UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case when building a Windows UNICODE target with Windows native SSL/TLS support enabled. Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage of these is hidden behind _tcsdup() which is MS way of dealing with code that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS header files and those compatible from other compilers use this preprocessor conditional compilation directive in order to select at compilation time whether 'wide' or 'ansi' MS API functions are used. Without this code, Windows build targets with Windows native SSL/TLS support enabled and MemoryTracking support enabled misbehave in tracking memory usage, regardless of being a UNICODE enabled build or not.
2013-07-17cmake: Fix for MSVC2010 project generationSergei Nikulov
Fixed issue with static build for MSVC2010. After some investigation I've discovered known issue http://public.kitware.com/Bug/view.php?id=11240 When .rc file is linked to static lib it fails with following linker error LINK : warning LNK4068: /MACHINE not specified; defaulting to X86 file.obj : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86' Fix add target property /MACHINE: for MSVC generation. Also removed old workarounds - it caused errors during msvc build. Bug: http://curl.haxx.se/mail/lib-2013-07/0046.html
2013-06-04sws: support extracting test number from CONNECT ipv6-address!Daniel Stenberg
If an ipv6-address is provided to CONNECT, the last hexadecimal group in the address will be used as the test number! For example the address "[1234::ff]" would be treated as test case 255.
2013-05-12Revert "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage"Daniel Stenberg
This reverts commit 8ec2cb5544b86306b702484ea785b6b9596562ab. We don't have any code anywhere in libcurl (or the curl tool) that use wcsdup so there's no such memory use to track. It seems to cause mild problems with the Borland compiler though that we may avoid by reverting this change again. Bug: http://curl.haxx.se/mail/lib-2013-05/0070.html
2013-04-06sockfilt.c: Fixed detection of client-side connection closeMarc Hoersken
WINSOCK only: Since FD_CLOSE is only signaled once, it may trigger at the same time as FD_READ. Data actually being available makes it impossible to detect that the connection was closed by checking that recv returns zero. Another recv attempt could block the connection if it was not closed. This workaround abuses exceptfds in conjunction with readfds to signal that the connection has actually closed.

2013-04-06util.c: Made write_pidfile write the correct PID on MinGW/MsysMarc Hoersken
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.

2013-03-27test1509: verify proxy header response headers countDaniel Stenberg
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. Bug: http://curl.haxx.se/bug/view.cgi?id=1204 Reported by: Martin Jansen
2013-03-25WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usageYang Tse
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.
