2010-01-29Implement pthread_cond_broadcast on WindowsLibravatar Johannes Sixt2-15/+94
See http://www.cse.wustl.edu/~schmidt/win32-cv-1.html, section "The SignalObjectAndWait solution". But note that this implementation does not use SignalObjectAndWait (which is needed to achieve fairness, but we do not need fairness). Note that our implementations of pthread_cond_broadcast and pthread_cond_signal require that they are invoked with the mutex held that is used in the pthread_cond_wait calls.

2010-01-22msvc: Fix an "unrecognized option" linker warningLibravatar Ramsay Jones1-0/+1
Having recently added support for building git-imap-send on Windows, we now link against OpenSSL libraries, and the linker issues the following warning: warning LNK4044: unrecognized option '/lssl'; ignored In order to suppress the warning, we change the msvc linker script to translate an '-lssl' parameter to the ssleay32.lib library. Note that the linker script was already including ssleay32.lib (along with libeay32.lib) as part of the translation of the '-lcrypto' library parameter. However, libeay32.dll does not depend on ssleay32.dll and can be used stand-alone, so we remove ssleay32.lib from the '-lcrypto' translation. The dependence of ssleay32.dll on libeay32.dll is represented in the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable. Also, add the corresponding change to the buildsystem generator.

2010-01-16Do not use date.c:tm_to_time_t() from compat/mingw.cLibravatar Johannes Sixt1-17/+19
To implement gettimeofday(), a broken-down UTC time was requested from the system using GetSystemTime(), then tm_to_time_t() was used to convert it to a time_t because it does not look at the current timezone, which mktime() would do. Use GetSystemTimeAsFileTime() and a different conversion path to avoid this back-reference from the compatibility layer to the generic code.

2010-01-16MSVC: Windows-native implementation for subset of Pthreads APILibravatar Andrzej K. Haczewski4-1/+183
This patch implements native to Windows subset of pthreads API used by Git. It allows to remove Pthreads for Win32 dependency for MSVC, msysgit and Cygwin. [J6t: If the MinGW build was built as part of the msysgit build environment, then threading was already enabled because the pthreads-win32 package is available in msysgit. With this patch, we can now enable threaded code unconditionally.] Signed-off-by: Andrzej K.

2010-01-16MSVC: Fix an "incompatible pointer types" compiler warningLibravatar Ramsay Jones2-25/+19
In particular, the following warning is issued while compiling compat/msvc.c: ...mingw.c(223) : warning C4133: 'function' : incompatible \ types - from '_stati64 *' to '_stat64 *' which relates to a call of _fstati64() in the mingw_fstat() function definition. This is caused by various layers of macro magic and attempts to avoid macro redefinition compiler warnings. For example, the call to _fstati64() mentioned above is actually a call to _fstat64(), and expects a pointer to a struct _stat64 rather than the struct _stati64 which is passed to mingw_fstat(). The definition of struct _stati64 given in compat/msvc.h had the same "shape" as the definition of struct _stat64, so the call to _fstat64() does not actually cause any runtime errors, but the structure types are indeed incompatible. In order to avoid the compiler warning, we add declarations for the mingw_lstat() and mingw_fstat() functions and supporting macros to msvc.h, suppressing the corresponding declarations in mingw.h, so that we can use the appropriate structure type (and function) names from the msvc headers.

2010-01-16Windows: avoid the "dup dance" when spawning a child processLibravatar Johannes Sixt2-9/+19
When stdin, stdout, or stderr must be redirected for a child process that on Windows is spawned using one of the spawn() functions of Microsoft's C runtime, then there is no choice other than to 1. make a backup copy of fd 0,1,2 with dup 2. dup2 the redirection source fd into 0,1,2 3. spawn 4. dup2 the backup back into 0,1,2 5. close the backup copy and the redirection source We used this idiom as well -- but we are not using the spawn() functions anymore! Instead, we have our own implementation. We had hardcoded that stdin, stdout, and stderr of the child process were inherited from the parent's fds 0, 1, and 2. But we can actually specify any fd. With this patch, the fds to inherit are passed from start_command()'s WIN32 section to our spawn implementation. This way, we can avoid the backup copies of the fds. The backup copies were a bug waiting to surface: The OS handles underlying the dup()ed fds were inherited by the child process (but were not associated with a file descriptor in the child). Consequently, the file or pipe represented by the OS handle remained open even after the backup copy was closed in the parent process until the child exited. Since our implementation of pipe() creates non-inheritable OS handles, we still dup() file descriptors in start_command() because dup() happens to create inheritable duplicates. (A nice side effect is that the fd cleanup in start_command is the same for Windows and Unix and remains unchanged.)

2010-01-16Windows: simplify the pipe(2) implementationLibravatar Johannes Sixt1-29/+8
Our implementation of pipe() must create non-inheritable handles for the reason that when a child process is started, there is no opportunity to close the unneeded pipe ends in the child (on POSIX this is done between fork() and exec()). Previously, we used the _pipe() function provided by Microsoft's C runtime (which creates inheritable handles) and then turned the handles into non-inheritable handles using the DuplicateHandle() API. Simplify the procedure by using the CreatePipe() API, which can create non-inheritable handles right from the beginning.

2010-01-16Windows: boost startup by avoiding a static dependency on shell32.dllLibravatar Johannes Sixt1-2/+14
This DLL is only needed to invoke the browser in a "git help" call. By looking up the only function that we need at runtime, we can avoid the startup costs of this DLL. DLL usage can be profiled with Microsoft's Dependency Walker. For example, a call to "git diff-files" loaded before: 19 DLLs after: 9 DLLs As a result, the runtime of 'make -j2 test' went down from 16:00min to 12:40min on one of my boxes.

* ms/msvc: Fix the exit code of MSVC build scripts on cygwin Fix MSVC build on cygwin
2009-10-08Fix the exit code of MSVC build scripts on cygwinLibravatar Ramsay Jones2-2/+2
During an MSVC build on cygwin, the make program did not notice when the compiler or linker exited with an error. This was caused by the scripts exiting with the value returned by system() directly. On POSIX-like systems, such as cygwin, the return value of system() has the exit code of the executed command encoded in the first byte (ie the value is shifted up by 8 bits). This allows the bottom 7 bits to contain the signal number of a terminated process, while the eighth bit indicates whether a core-dump was produced. (A value of -1 indicates that the command failed to execute.) The make program, however, expects the exit code to be encoded in the bottom byte. Futhermore, it apparently masks off and ignores anything in the upper bytes. However, these scripts are (naturally) intended to be used on the windows platform, where we can not assume POSIX-like semantics from a perl implementation (eg ActiveState). So, in general, we can not assume that shifting the return value right by eight will get us the exit code. In order to improve portability, we assume that a zero return from system() indicates success, whereas anything else indicates failure. Since we don't need to know the exact exit code from the compiler or linker, we simply exit with 0 (success) or 1 (failure).

2009-10-02Fix some printf format warningsLibravatar Ramsay Jones1-2/+2
commit 51ea551 ("make sure byte swapping is optimal for git" 2009-08-18) introduced a "sane definition for ntohl()/htonl()" for use on some GNU C platforms. Unfortunately, for some of these platforms, this results in the introduction of a problem which is essentially the reverse of a problem that commit 6e1c234 ("Fix some warnings (on cygwin) to allow -Werror" 2008-07-3) was intended to fix. In particular, on platforms where the uint32_t type is defined to be unsigned long, the return type of the new ntohl()/htonl() is causing gcc to issue printf format warnings, such as: warning: long unsigned int format, unsigned int arg (arg 3) (nine such warnings, covering six different files). The earlier commit (6e1c234) needed to suppress these same warnings, except that the types were in the opposite direction; namely the format specifier ("%u") was 'unsigned int' and the argument type (ie the return type of ntohl()) was 'long unsigned int' (aka uint32_t). In order to suppress these warnings, the earlier commit used the (C99) PRIu32 format specifier, since the definition of this macro is suitable for use with the uint32_t type on that platform. This worked because the return type of the (original) platform ntohl()/htonl() functions was uint32_t. In order to suppress these warnings, we change the return type of the new byte swapping functions in the compat/bswap.h header file from 'unsigned int' to uint32_t.

2009-09-18Add scripts to generate projects for other buildsystems (MSVC vcproj, QMake)Libravatar Marius Storm-Olsen1-1/+12
These scripts generate projects for the MSVC IDE (.vcproj files) or QMake (.pro files), based on the output of a 'make -n MSVC=1 V=1' run. This enables us to simply do the necesarry changes in the Makefile, and you can update the other buildsystems by regenerating the files. Keeping the other buildsystems up-to-date with main development. The generator system is designed to easily drop in pm's for other buildsystems as well, if someone has an itch. However, the focus has been Windows development, so the 'engine' might need patches to support any platform. Also add some .gitignore entries for MSVC files.

Centralize the include of windows.h in git-compat-util.h, turn on WIN32_LEAN_AND_MEAN to avoid including plenty of other header files which is not needed in Git. Also ensure we load winsock2.h first, so we don't load the older winsock definitions at a later stage, since they contain duplicate definitions. When moving windows.h into git-compat-util.h, we need to protect the definition of struct pollfd in mingw.h, since this file is used by both MinGW and MSVC, and the latter defines this struct in winsock2.h. We need to keep the windows.h include in compat/win32.h, since its shared by both MinGW and Cygwin, and we're not touching Cygwin in this commit. The include in git-compat-util.h is protected with an ifdef WIN32, which is not the case when compiling for Cygwin.

2009-06-01MinGW readdir reimplementation to support d_typeLibravatar Marius Storm-Olsen2-0/+88
The original readdir implementation was fast, but didn't support the d_type. This means that git would do additional lstats for each entry, to figure out if the entry was a directory or not. This unneedingly slowed down many operations, since Windows API provides this information directly when walking the directories. By running this implementation on Moe's repo structure: mkdir bummer && cd bummer; for ((i=0;i<100;i++)); do mkdir $i && pushd $i; for ((j=0;j<1000;j++)); do echo "$j" >$j; done; popd; done We see the following speedups: git add . ------------------- old: 00:00:23(.087) new: 00:00:21(.512) 1.07x git status ------------------- old: 00:00:03(.306) new: 00:00:01(.684) 1.96x git clean -dxf ------------------- old: 00:00:01(.918) new: 00:00:00(.295) 6.50x Signed-off-by: Marius Storm-Olsen <marius@trolltech.com> Signed-off-by: Steffen Prohaska <prohaska@zib.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-06-01Work around a regression in Windows 7, causing erase_in_line() to crash ↵Libravatar Johannes Schindelin1-1/+2
sometimes The function FillConsoleOutputCharacterA() was pretty content in XP to take a NULL pointer if we did not want to store the number of written columns. In Windows 7, it crashes, but only when called from within Git Bash, not from within cmd.exe. Go figure.

2009-05-31compat: add a basename() compatibility functionLibravatar David Aguilar1-0/+15
Some systems such as Windows lack libgen.h so provide a basename() implementation for cross-platform use. This introduces the NO_LIBGEN_H construct to the Makefile and autoconf scripts. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
