In 554544276a (*.[ch]: remove extern from function declarations using spatch, 2019-04-29), we removed externs from function declarations using spatch but we intentionally excluded files under compat/ since some are directly copied from an upstream and we should avoid churning them so that manually merging future updates will be simpler. In the last commit, we determined the files which taken from an upstream so we can exclude them and run spatch on the remainder. This was the Coccinelle patch used: @@ type T; identifier f; @@ - extern T f(...); and it was run with: $ git ls-files compat/\*\*.{c,h} | xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place $ git checkout -- \ compat/regex/ \ compat/inet_ntop.c \ compat/inet_pton.c \ compat/nedmalloc/ \ compat/obstack.{c,h} \ compat/poll/ Coccinelle has some trouble dealing with `__attribute__` and varargs so we ran the following to ensure that no remaining changes were left behind: $ git ls-files compat/\*\*.{c,h} | xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/' $ git checkout -- \ compat/regex/ \ compat/inet_ntop.c \ compat/inet_pton.c \ compat/nedmalloc/ \ compat/obstack.{c,h} \ compat/poll/ Signed-off-by: Denton Liu <liu.denton@gmail.com> Acked-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-06-27mingw: embed a manifest to trick UAC into Doing The Right ThingLibravatar Cesar Eduardo Barros1-0/+25
On Windows >= Vista, not having an application manifest with a requestedExecutionLevel can cause several kinds of confusing behavior. The first and more obvious behavior is "Installer Detection" of the "User Account Control" (also known as "UAC") feature, where Windows sometimes decides (by looking at things like the file name and even sequences of bytes within the executable) that an executable is an installer and should run elevated (causing the well-known popup dialog to appear). In Git's context, subcommands such as "git patch-id" or "git update-index" fall prey to this behavior. The second and more confusing behavior is "File Virtualization". It means that when files are written without having write permission, it does not fail (as expected), but they are instead redirected to somewhere else. When the files are read, the original contents are returned, though, not the ones that were just written somewhere else. Even more confusing, not all write accesses are redirected; Trying to write to write-protected .exe files, for example, will fail instead of redirecting. In addition to being unwanted behavior, File Virtualization causes dramatic slowdowns in Git (see for instance http://code.google.com/p/msysgit/issues/detail?id=320). A third unwanted behavior of Windows >= Vista is that it lies about the Windows version when calling `GetWindowsVersionEx()`. There are two ways to prevent these unwanted behaviors: Either you embed an application manifest (which really is an XML document conforming to a specific schema) within all your executables, or you add an external manifest (a file with the same name followed by `.manifest`) to all your executables. Since Git's builtins are hardlinked (or copied), it is simpler and more robust to embed a manifest. Recent enough MSVC compilers already embed a working internal manifest, and building with mingw-w64 (which is the case in Git for Windows' SDK) does it, too, but for MinGW you have to do so by hand. In any case, it is better to be explicit about this manifest, that way changes in the compiler toolchain won't surprise us (as mingw-w64 once did when it broke `GetWindowsVersionEx()` by mistake).

2018-12-26git clone <url> C:\cygwin\home\USER\repo' is working (again)Libravatar Torsten Bögershausen2-0/+48
A regression for cygwin users was introduced with commit 05b458c, "real_path: resolve symlinks by hand". In the the commit message we read: The current implementation of real_path uses chdir() in order to resolve symlinks. Unfortunately this isn't thread-safe as chdir() affects a process as a whole... The old (and non-thread-save) OS calls chdir()/pwd() had been replaced by a string operation. The cygwin layer "knows" that "C:\cygwin" is an absolute path, but the new string operation does not. "git clone <url> C:\cygwin\home\USER\repo" fails like this: fatal: Invalid path '/home/USER/repo/C:\cygwin\home\USER\repo' The solution is to implement has_dos_drive_prefix(), skip_dos_drive_prefix() is_dir_sep(), offset_1st_component() and convert_slashes() for cygwin in the same way as it is done in 'Git for Windows' in compat/mingw.[ch] Extract the needed code into compat/win32/path-utils.[ch] and use it for cygwin as well.

The Win32 CONDITION_VARIABLE has better performance and is easier to maintain, as the code is a lot shorter now (the semantics of the CONDITION_VARIABLE matches the pthread_cond_t very well). Note: CONDITION_VARIABLE is not available in Windows XP and below, but the declared minimal Windows version required to build and run Git for Windows is Windows Vista (which is also beyond its end-of-life, but for less long than Windows XP), so that's okay.

2017-09-26Win32: simplify loading of DLL functionsLibravatar Johannes Schindelin1-0/+57
Dynamic loading of DLL functions is duplicated in several places in Git for Windows' source code. This patch adds a pair of macros to simplify the process: the DECLARE_PROC_ADDR(<dll>, <return-type>, <function-name>, ...<function-parameter-types>...) macro to be used at the beginning of a code block, and the INIT_PROC_ADDR(<function-name>) macro to call before using the declared function. The return value of the INIT_PROC_ADDR() call has to be checked; If it is NULL, the function was not found in the specified DLL. Example: DECLARE_PROC_ADDR(kernel32.dll, BOOL, CreateHardLinkW, LPCWSTR, LPCWSTR, LPSECURITY_ATTRIBUTES); if (!INIT_PROC_ADDR(CreateHardLinkW)) return error("Could not find CreateHardLinkW() function"; if (!CreateHardLinkW(source, target, NULL)) return error("could not create hardlink from %S to %S", source, target); return 0; Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In f924b52 (Windows: add pthread_sigmask() that does nothing, 2016-05-01), we introduced a no-op for Windows. However, this breaks building Git in Git for Windows' SDK because pthread_sigmask() is already a no-op there, #define'd in the pthread_signal.h header in /mingw64/x86_64-w64-mingw32/include/. Let's wrap the definition of pthread_sigmask() in a guard that skips it when compiling with MinGW-w64' headers.

2016-05-02Windows: add pthread_sigmask() that does nothingLibravatar Johannes Sixt1-0/+5
A previous change introduced a call to pthread_sigmask() in order to block SIGPIPE in a thread. Since there are no signal facilities on Windows that are similar to POSIX signals, just ignore the request to block the signal. In the particular case, the effect of blocking SIGPIPE on POSIX is that write() calls return EPIPE when the reader closes the pipe. This is how write() behaves on Windows.

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).

Both XSI and upstream Gnulib versions expects to find poll.h at the root of some include path, not inside the sys-folder. This helps us when upgrading Gnulib. Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Acked-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.
