2014-07-15Win32: Unicode file name support (dirent)Libravatar Karsten Blees2-21/+11
Changes opendir/readdir to use Windows Unicode APIs and convert between UTF-8/UTF-16. Removes parameter checks that are already covered by xutftowcs_path. This changes detection of ENAMETOOLONG from MAX_PATH - 2 to MAX_PATH (matching is_dir_empty in mingw.c). If name + "/*" or the resulting absolute path is too long, FindFirstFile fails and errno is set through err_win_to_posix. Increases the size of dirent.d_name to accommodate the full WIN32_FIND_DATA.cFileName converted to UTF-8 (UTF-16 to UTF-8 conversion may grow by factor three in the worst case).

2014-06-09Win32 dirent: improve dirent implementationLibravatar Karsten Blees1-59/+54
Improve the dirent implementation by removing the relics that were once necessary to plug into the now unused MinGW runtime, in preparation for Unicode file name support. Move FindFirstFile to opendir, and FindClose to closedir, with the following implications: - DIR.dd_name is no longer needed - chdir(one); opendir(relative); chdir(two); readdir() works as expected (i.e. lists one/relative instead of two/relative) - DIR.dd_handle is a valid handle for the entire lifetime of the DIR struct - thus, all checks for dd_handle == INVALID_HANDLE_VALUE and dd_handle == 0 have been removed - the special case that the directory has been fully read (which was previously explicitly tracked with dd_handle == INVALID_HANDLE_VALUE && dd_stat != 0) is now handled implicitly by the FindNextFile error handling code (if a client continues to call readdir after receiving NULL, FindNextFile will continue to fail with ERROR_NO_MORE_FILES, to the same effect) - extracting dirent data from WIN32_FIND_DATA is needed in two places, so moved to its own method - GetFileAttributes is no longer needed. The same information can be obtained from the FindFirstFile error code, which is ERROR_DIRECTORY if the name is NOT a directory (-> ENOTDIR), otherwise we can use err_win_to_posix (e.g. ERROR_PATH_NOT_FOUND -> ENOENT). The ERROR_DIRECTORY case could be fixed in err_win_to_posix, but this probably breaks other functionality. Removes the ERROR_NO_MORE_FILES check after FindFirstFile (this was fortunately a NOOP (searching for '*' always finds '.' and '..'), otherwise the subsequent code would have copied data from an uninitialized buffer). Changes malloc to git support function xmalloc, so opendir will die() if out of memory, rather than failing with ENOMEM and letting git work on incomplete directory listings (error handling in dir.c is quite sparse).

2014-06-09Win32 dirent: change FILENAME_MAX to MAX_PATHLibravatar Karsten Blees1-1/+1
FILENAME_MAX and MAX_PATH are both 260 on Windows, however, MAX_PATH is used throughout the other Win32 code in Git, and also defines the length of file name buffers in the Win32 API (e.g. WIN32_FIND_DATA.cFileName, from which we're copying the dirent data).

2014-04-09mingw: activate allocaLibravatar Kirill Smelkov1-0/+1
Both MSVC and MINGW have alloca(3) definitions in malloc.h, so by moving win32-compat alloca.h from compat/vcbuild/include/ to compat/win32/ , which is included by both MSVC and MINGW CFLAGS, we can make alloca() work on both those Windows environments. In MINGW, malloc.h has explicit check for GNUC and if it is so, defines alloca to __builtin_alloca, so it looks like we don't need to add any code to here-shipped alloca.h to get optimum performance.

2013-04-28compat/win32/pthread.c: Fix a sparse warningLibravatar Ramsay Jones1-1/+1
Sparse issues a 'Using plain integer as NULL pointer' warning when initializing an pthread_t structure with an '{ 0 }' initializer. The first field of the pthread_t structure has type HANDLE (void *), so in order to suppress the warning, we replace the initializer expression with '{ NULL }'.

2011-10-07mingw: avoid using strbuf in syslogLibravatar Erik Faye-Lund1-12/+18
strbuf can call die, which again can call syslog from git-daemon. Endless recursion is no fun; fix it by hand-rolling the logic. As a side-effect malloc/realloc errors are changed into non-fatal warnings; this is probably an improvement anyway.

2010-12-09msvc: Fix compilation errors in compat/win32/sys/poll.cLibravatar Ramsay Jones1-0/+3
The msvc winsock2.h header file conditionally defines or declares poll() related symbols which cause many macro redefinition errors, a struct type redefinition error and syntax errors. These symbols are defined in support of the WSAPoll() API, new in Windows Vista, when the symbol _WIN32_WINNT is defined and _WIN32_WINNT >= 0x0600. In order to avoid the compilation errors, we set _WIN32_WINNT to 0x0502 (which would target Windows Server 2003) prior to including the winsock2.h header file.

2010-11-23win32: use our own dirent.hLibravatar Erik Faye-Lund2-0/+132
The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be read due to EMFILE") introduce a dependency on this behaviour, leading to a broken "git clone" on Windows. compat/mingw.c contains an implementation of readdir, and compat/msvc.c contains implementations of opendir and closedir. Move these to compat/win32/dirent.[ch], and change to our own DIR structure at the same time. This provides a generic Win32-implementation of opendir, readdir and closedir which works on both MinGW and MSVC and does not reset errno, and as a result git clone is working again on Windows.

2010-11-04mingw: implement syslogLibravatar Mike Pape2-0/+92
Syslog does not usually exist on Windows, so implement our own using Window's ReportEvent mechanism. Strings containing "%1" gets expanded into them selves by ReportEvent, resulting in an unreadable string. "%2" and above is not a problem. Unfortunately, on Windows an IPv6 address can contain "%1", so expand "%1" to "% 1" before reporting. "%%1" is also a problem for ReportEvent, but that string cannot occur in an IPv6 address.

2010-04-08Thread-safe xmalloc and xrealloc needs a recursive mutexLibravatar Johannes Sixt1-1/+7
The mutex used to protect object access (read_mutex) may need to be acquired recursively. Introduce init_recursive_mutex() helper function in thread-utils.c that constructs a mutex with the PHREAD_MUTEX_RECURSIVE attribute. pthread_mutex_init() emulation on Win32 is already recursive as it is implemented on top of the CRITICAL_SECTION type, which is recursive. http://msdn.microsoft.com/en-us/library/ms682530%28VS.85%29.aspx Add do-nothing compatibility wrappers for pthread_mutexattr* functions.

2010-01-16MSVC: Windows-native implementation for subset of Pthreads APILibravatar Andrzej K. Haczewski2-0/+177
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.
