| * compat/mingw.c: Teach mingw_rename() to replace read-only filesJohannes Sixt2008-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | On POSIX, rename() can replace files that are not writable. On Windows, however, read-only files cannot be replaced without additional efforts: We have to make the destination writable first. Since the situations where the destination is read-only are rare, we do not make the destination writable on every invocation, but only if the first try to rename a file failed with an "access denied" error.

* | Windows: Make OpenSSH properly detect tty detachment.Alexander Gavrilov2008-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently, CREATE_NO_WINDOW makes the OS tell the process that it has a console, but without actually creating the window. As a result, when git is started from GUI, ssh tries to ask its questions on the invisible console. This patch uses DETACHED_PROCESS instead, which clearly means that the process should be left without a console. The downside is that if the process manually calls AllocConsole, the window will appear. A similar thing might occur if it calls another console executable.

* | compat/cygwin.c: make runtime detection of lstat/stat lessor impactJunio C Hamano2008-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original patch that lead to an earlier commit adbc0b6 (cygwin: Use native Win32 API for stat, 2008-09-30) did not call git_default_config() and it was a good thing. The lazy config reading when lstat/stat is called for the first time to find out if core.filemode is set can happen anytime in the calling program. If it happens after the calling program parsed the configuration file to prime its default parameter settings and processed its command line parameters to tweak them, this will overwrite the values set by the program with the values read from the config file. This essentially reverts the code to the version as submitted by Mark, with a bit more comments to clarify why we do not fall back on the default configuration parser from git_cygwin_config().

* | compat/cygwin.c - Use cygwin's stat if core.filemode == trueMark Levedahl2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | Cygwin's POSIX emulation allows use of core.filemode true, unlike native Window's implementation of stat / lstat, and Cygwin/git users who have configured core.filemode true in various repositories will be very unpleasantly surprised to find that git is no longer honoring that option. So, this patch forces use of Cygwin's stat functions if core.filemode is set true, regardless of any other considerations.

* | cygwin: Use native Win32 API for statDmitry Potapov2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lstat/stat functions in Cygwin are very slow, because they try to emulate some *nix things that Git does not actually need. This patch adds Win32 specific implementation of these functions for Cygwin. This implementation handles most situation directly but in some rare cases it falls back on the implementation provided for Cygwin. This is necessary for two reasons: - Cygwin has its own file hierarchy, so absolute paths used in Cygwin is not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be used because it automatically dereference Cygwin symbol links, also it causes extra syscall. Fortunately Git rarely use absolute paths, so we always use Cygwin implementation for absolute paths. - Support of symbol links. Cygwin stores symbol links as ordinary using one of two possible formats. Therefore, the fast implementation falls back to Cygwin functions if it detects potential use of symbol links. The speed of this implementation should be the same as mingw_lstat for common cases, but it is considerable slower when the specified file name does not exist. Despite all efforts to make the fast implementation as robust as possible, it may not work well for some very rare situations. I am aware only one situation: use Cygwin mount to bind unrelated paths inside repository together. Therefore, the core.ignoreCygwinFSTricks configuration option is provided, which controls whether native or Cygwin version of stat is used.

This breaks the diff.funcname functionality on OSX. To fix this, we use the GNU regex library which is already present in the compat/ diretory for the MinGW port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms provide a horribly broken snprintf. More broken than the platforms that return -1 when there is too little space in the target buffer for the formatted string. Some platforms provide an snprintf which _always_ returns the number of characters transmitted to the buffer, regardless of whether there was enough space or not. IRIX 6.5 is such a platform. IRIX does have a working snprintf(), but it is only provided when _NO_XOPEN5 evaluates to zero, and this only happens if _XOPEN_SOURCE is defined, but definition of _XOPEN_SOURCE prevents inclusion of many other common functions and defines. So it must be avoided. Work around these horribly broken snprintf implementations by detecting an snprintf call which results in the number of transmitted characters exactly equal to the length of our buffer and retrying with a larger buffer just to be safe.

Unfortunately, if a program is invoked from CMD, argv[0] has no path. But on the other hand, the C runtime offers a global variable, _pgmptr, that always has the full path to the program.

* help (Windows): Display HTML in default browser using Windows' shell APISteffen Prohaska2008-07-13
| | | | | | | | | | | | | | | | | | | | The system's default browser for displaying HTML help pages is now used directly on Windows, instead of launching git-web--browser, which requires a Unix shell. Avoiding MSYS' bash when possible is good because it avoids potential path translation issues. In this case it is not too hard to avoid launching a shell, so let's avoid it. The Windows-specific code is implemented in compat/mingw.c to avoid platform-specific code in the main code base. On Windows, open_html is provided as a define. If open_html is not defined, git-web--browse is used. This approach avoids platform-specific ifdefs by using per-function ifdefs. The "ifndef open_html" together with the introductory comment should sufficiently warn developers, so that they hopefully will not break this mechanism.

* Windows: Fix ntohl() related warnings about printf formattingSteffen Prohaska2008-06-26
| | | | | | | | | | | | | | On Windows, ntohl() returns unsigned long. On Unix it returns uint32_t. This makes choosing a suitable printf format string hard. This commit introduces a mingw specific helper function git_ntohl() that casts to unsigned int before returning. This makes gcc's printf format check happy.

* Windows: Add a custom implementation for utime().Johannes Sixt2008-06-26
| | | | | | | | | | This is a necessary pendant to our lstat implementation: MSVCRT's implementations of lstat and utime do some adjustments if daylight saving time is in effect, but our lstat implementation doesn't do these adjustments and report the correct UTC time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gives us a significant speedup when adding, committing and stat'ing files. Also, since Windows doesn't really handle symlinks, we let stat just uses lstat. We also need to replace fstat, since our implementation and the standard stat() functions report slightly different timestamps, possibly due to timezones. We simply report UTC in our implementation, and do our FILETIME to time_t conversion based on the document at http://support.microsoft.com/kb/167296.

* Windows: Implement a custom spawnve().Johannes Sixt2008-06-26
| | | | | | | | | | | | | | | | | | | | | The problem with Windows's own implementation is that it tries to be clever when a console program is invoked from a GUI application: In this case it sometimes automatically allocates a new console window. As a consequence, the IO channels of the spawned program are directed to the console, but the invoking application listens on channels that are now directed to nowhere. In this implementation we use the lowlevel facilities of CreateProcess(), which offers a flag to tell the system not to open a console. As a side effect, only stdin, stdout, and stderr channels will be accessible from C programs that are spawned. Other channels (file handles, pipe handles, etc.) are still inherited by the spawned program, but it doesn't get enough information to access them. Johannes Schindelin integrated path quoting and unified the various *execv* and *spawnv* helpers. Eric Raible suggested to also quote '{'. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
* Windows: Implement wrappers for gethostbyname(), socket(), and connect().Johannes Sixt2008-06-26
| | | | | | | | | | | | | | | | | | gethostbyname() is the first function that calls into the Winsock library, and it is wrapped only to initialize the library. socket() is wrapped for two reasons: - Windows's socket() creates things that are like low-level file handles, and they must be converted into file descriptors first. - And these handles cannot be used with plain ReadFile()/WriteFile() because they are opened for "overlapped IO". We have to use WSASocket() to create non-overlapped IO sockets. connect() must be wrapped because Windows's connect() expects the low-level sockets, not file descriptors, and we must first unwrap the file descriptor before we can pass it on to Windows's connect().

* Windows: A rudimentary poll() emulation.Johannes Sixt2008-06-26
| | | | | | | | | | | | | | | This emulation of poll() is by far not general. It assumes that the fds that are to be waited for are connected to pipes. The pipes are polled in a loop until data becomes available in at least one of them. If only a single fd is waited for, the implementation actually does not wait at all, but assumes that a subsequent read() will block. In order not to needlessly burn CPU time, the CPU is yielded to other processes before the next round in the poll loop using Sleep(0). Note that any sleep timeout greater than zero will reduce the efficiency by a magnitude. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
* Windows: Implement start_command().Johannes Sixt2008-06-23
| | | | | | | | | | | | | | | | On Windows, we have spawnv() variants to run a child process instead of fork()/exec(). In order to attach pipe ends to stdin, stdout, and stderr, we have to use this idiom: save1 = dup(1); dup2(pipe[1], 1); spawnv(); dup2(save1, 1); close(pipe[1]); assuming that the descriptors created by pipe() are not inheritable.

* Windows: A pipe() replacement whose ends are not inherited to children.Johannes Sixt2008-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Unix the idiom to use a pipe is as follows: pipe(fd); pid = fork(); if (!pid) { dup2(fd[1], 1); close(fd[1]); close(fd[0]); ... } close(fd[1]); i.e. the child process closes the both pipe ends after duplicating one to the file descriptors where they are needed. On Windows, which does not have fork(), we never have an opportunity to (1) duplicate a pipe end in the child, (2) close unused pipe ends. Instead, we must use this idiom: save1 = dup(1); pipe(fd); dup2(fd[1], 1); spawn(...); dup2(save1, 1); close(fd[1]); i.e. save away the descriptor at the destination slot, replace by the pipe end, spawn process, restore the saved file. But there is a problem: Notice that the child did not only inherit the dup2()ed descriptor, but also *both* original pipe ends. Although the one end that was dup()ed could be closed before the spawn(), we cannot close the other end - the child inherits it, no matter what. The solution is to generate non-inheritable pipes. At the first glance, this looks strange: The purpose of pipes is usually to be inherited to child processes. But notice that in the course of actions as outlined above, the pipe descriptor that we want to inherit to the child is dup2()ed, and as it so happens, Windows's dup2() creates inheritable duplicates.

We have to translate backslashes to forward slashes in the prefix and in command line arguments. Fortunately, all of them are passed through functions in setup.c. A macro has_dos_drive_path() is defined that checks whether a path begins with a drive letter+colon combination. This predicate is always false on Unix. Another macro is_dir_sep() abstracts that a backslash is also a directory separator on Windows. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>

| | | | | | | | | | | Some systems define fopen as a macro based on compiler settings. The previous technique for reverting to the system fopen function by merely undefining fopen is inadequate in this case. Instead, avoid defining fopen entirely when compiling this source file.

* Add compat/snprintf.c for systems that return bogusMichal Rokos2008-03-05
| | | | | | | | | | | | | Some systems (namely HPUX and Windows) return -1 when maxsize in snprintf() and in vsnprintf() is reached. So replace snprintf() and vsnprintf() functions with our own ones that return correct value upon overflow. [jc: verified that review comments by J6t have been incorporated, and tightened the check to verify the resulting buffer contents, suggested by Wayne Davison] Signed-off-by: Michal Rokos <michal.rokos@nextsoft.cz> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | compat: Add simplified merge sort implementation from glibcBrian Downing2008-02-06
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qsort in Windows 2000 (and various other C libraries) is a Quicksort with the usual O(n^2) worst case. Unfortunately, sorting Git trees seems to get very close to that worst case quite often: $ /git/gitbad runstatus # On branch master qsort, nmemb = 30842 done, 237838087 comparisons. This patch adds a simplified version of the merge sort that is glibc's qsort(3). As a merge sort, this needs a temporary array equal in size to the array that is to be sorted, but has a worst-case performance of O(n log n). The complexity that was removed is: * Doing direct stores for word-size and -aligned data. * Falling back to quicksort if the allocation required to perform the merge sort would likely push the machine into swap. Even with these simplifications, this seems to outperform the Windows qsort(3) implementation, even in Windows XP (where it is "fixed" and doesn't trigger O(n^2) complexity on trees).

* | Define compat version of mkdtemp for systems lacking itShawn O. Pearce2007-10-20
| | | | | | | | | | | | | | | | | | | | Solaris 9 doesn't have mkdtemp() so we need to emulate it for the rsync transport implementation. Since Solaris 9 is lacking this function we can also reasonably assume it is not available on Solaris 8 either. The new Makfile definition NO_MKDTEMP can be set to enable the git compat version.
