cygwin can use an UNC path like //server/share/repo $ cd //server/share/dir $ mkdir test $ cd test $ git init --bare However, when we try to push from a local Git repository to this repo, there is a problem: Git converts the leading "//" into a single "/". As cygwin handles an UNC path so well, Git can support them better: - Introduce cygwin_offset_1st_component() which keeps the leading "//", similar to what Git for Windows does. - Move CYGWIN out of the POSIX in the tests for path normalization in t0060 Signed-off-by: NTorsten Bögershausen <tboegi@web.de> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Amend my change earlier in this series ("grep: add support for the PCRE v1 JIT API", 2017-04-11) to un-break the build on PCRE v1 versions later than 8.31 compiled without --enable-jit. As explained in that change and a later compatibility change in this series ("grep: un-break building with PCRE < 8.32", 2017-05-10) the pcre_jit_exec() function is a faster path to execute the JIT. Unfortunately there's no compatibility stub for that function compiled into the library if pcre_config(PCRE_CONFIG_JIT, &ret) would return 0, and no macro that can be used to check for it, so the only portable option to support builds without --enable-jit is via a new NO_LIBPCRE1_JIT=UnfortunatelyYes Makefile option[1]. Another option would be to make the JIT opt-in via USE_LIBPCRE1_JIT=YesPlease, after all it's not a default option of PCRE v1. I think it makes more sense to make it opt-out since even though it's not a default option, most packagers of PCRE seem to turn it on by default, with the notable exception of the MinGW package. Make the MinGW platform work by default by changing the build defaults to turn on NO_LIBPCRE1_JIT=UnfortunatelyYes. It is the only platform that turns on USE_LIBPCRE=YesPlease by default, see commit df5218b4 ("config.mak.uname: support MSys2", 2016-01-13) for that change. 1.

Use OpenSSL's SHA-1 routines rather than builtin block-sha1 routines. This improves performance on SHA1 operations on Intel processors. OpenSSL 1.0.2 has made considerable performance improvements and support the Intel hardware acceleration features. See: https://software.intel.com/en-us/articles/improving-openssl-performance https://software.intel.com/en-us/articles/intel-sha-extensions To test this I added/staged a single file in a gigantic repository having a 450MB index file. The code in read-cache.c verifies the header SHA as it reads the index and computes a new header SHA as it writes out the new index. Therefore, in this test the SHA code must process 900MB of data. Testing was done on an Intel I7-4770 CPU @ 3.40GHz (Intel64, Family 6, Model 60) CPU. The block-sha1 version averaged 5.27 seconds. The OpenSSL version averaged 4.50 seconds. ================================================================ $ echo xxx >> project.mk $ time /e/blk_sha/bin/git.exe add project.mk real 0m5.207s user 0m0.000s sys 0m0.250s $ echo xxx >> project.mk $ time /e/blk_sha/bin/git.exe add project.mk real 0m5.362s user 0m0.015s sys 0m0.234s $ echo xxx >> project.mk $ time /e/blk_sha/bin/git.exe add project.mk real 0m5.300s user 0m0.016s sys 0m0.250s $ echo xxx >> project.mk $ time /e/blk_sha/bin/git.exe add project.mk real 0m5.216s user 0m0.000s sys 0m0.250s ================================================================ $ echo xxx >> project.mk $ time /e/openssl/bin/git.exe add project.mk real 0m4.431s user 0m0.000s sys 0m0.250s $ echo xxx >> project.mk $ time /e/openssl/bin/git.exe add project.mk real 0m4.478s user 0m0.000s sys 0m0.265s $ echo xxx >> project.mk $ time /e/openssl/bin/git.exe add project.mk real 0m4.690s user 0m0.000s sys 0m0.250s $ echo xxx >> project.mk $ time /e/openssl/bin/git.exe add project.mk real 0m4.420s user 0m0.000s sys 0m0.234s ================================================================ Signed-off-by: NJeff Hostetler <jeffhost@microsoft.com> Signed-off-by: NJohannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The xdiff code hashes every line of both sides of a diff, and then compares those hashes to find duplicates. The overall performance depends both on how fast we can compute the hashes, but also on how many hash collisions we see. The idea of XDL_FAST_HASH is to speed up the hash computation. But the generated hashes have worse collision behavior. This means that in some cases it speeds diffs up (running "git log -p" on git.git improves by ~8% with it), but in others it can slow things down. One pathological case saw over a 100x slowdown[1]. There may be a better hash function that covers both properties, but in the meantime we are better off with the original hash. It's slightly slower in the common case, but it has fewer surprising pathological cases.

MSYS2 emulates pseudo terminals via named pipes, and isatty() returns 0 for such file descriptors. Therefore, some interactive functionality (such as launching a pager, asking if a failed unlink should be repeated etc.) doesn't work when run in a terminal emulator that uses MSYS2's ptys (such as mintty). However, MSYS2 uses special names for its pty pipes ('msys-*-pty*'), which allows us to distinguish them from normal piped input / output. On startup, check if stdin / stdout / stderr are connected to such pipes using the NtQueryObject API from NTDll.dll. If the names match, adjust the flags in MSVCRT's ioinfo structure accordingly.

For a long time, Git for Windows lagged behind Git's 2.x releases because the Git for Windows developers wanted to let that big jump coincide with a well-needed jump away from MSys to MSys2. To understand why this is such a big issue, it needs to be noted that many parts of Git are not written in portable C, but instead Git relies on a POSIX shell and Perl to be available. To support the scripts, Git for Windows has to ship a minimal POSIX emulation layer with Bash and Perl thrown in, and when the Git for Windows effort started in August 2007, this developer settled on using MSys, a stripped down version of Cygwin. Consequently, the original name of the project was "msysGit" (which, sadly, caused a *lot* of confusion because few Windows users know about MSys, and even less care). To compile the C code of Git for Windows, MSys was used, too: it sports two versions of the GNU C Compiler: one that links implicitly to the POSIX emulation layer, and another one that targets the plain Win32 API (with a few convenience functions thrown in). Git for Windows' executables are built using the latter, and therefore they are really just Win32 programs. To discern executables requiring the POSIX emulation layer from the ones that do not, the latter are called MinGW (Minimal GNU for Windows) when the former are called MSys executables. This reliance on MSys incurred challenges, too, though: some of our changes to the MSys runtime -- necessary to support Git for Windows better -- were not accepted upstream, so we had to maintain our own fork. Also, the MSys runtime was not developed further to support e.g. UTF-8 or 64-bit, and apart from lacking a package management system until much later (when mingw-get was introduced), many packages provided by the MSys/MinGW project lag behind the respective source code versions, in particular Bash and OpenSSL. For a while, the Git for Windows project tried to remedy the situation by trying to build newer versions of those packages, but the situation quickly became untenable, especially with problems like the Heartbleed bug requiring swift action that has nothing to do with developing Git for Windows further. Happily, in the meantime the MSys2 project (https://msys2.github.io/) emerged, and was chosen to be the base of the Git for Windows 2.x. Just like MSys, MSys2 is a stripped down version of Cygwin, but it is actively kept up-to-date with Cygwin's source code. Thereby, it already supports Unicode internally, and it also offers the 64-bit support that we yearned for since the beginning of the Git for Windows project. MSys2 also ported the Pacman package management system from Arch Linux and uses it heavily. This brings the same convenience to which Linux users are used to from `yum` or `apt-get`, and to which MacOSX users are used to from Homebrew or MacPorts, or BSD users from the Ports system, to MSys2: a simple `pacman -Syu` will update all installed packages to the newest versions currently available. MSys2 is also *very* active, typically providing package updates multiple times per week. It still required a two-month effort to bring everything to a state where Git's test suite passes, many more months until the first official Git for Windows 2.x was released, and a couple of patches still await their submission to the respective upstream projects. Yet without MSys2, the modernization of Git for Windows would simply not have happened. This commit lays the ground work to supporting MSys2-based Git builds.

On Mac OS X, getdelim() first became available with Xcode 4.1[1], which was released the same day as OS X 10.7 "Lion", so assume getdelim() availability from 10.7 onward. (As of this writing, OS X is at 10.10 "Yosemite".) According to Wikipedia[2], 4.1 was also available for download by paying developers on OS X 10.6 "Snow Leopard", so it's possible that some 10.6 machines may have getdelim(). However, as strbuf's use of getdelim() is purely an optimization, let's be conservative and assume 10.6 and earlier lack getdelim().

We spend a lot of time in strbuf_getwholeline in a tight loop reading characters from a stdio handle into a buffer. The libc getdelim() function can do this for us with less overhead. It's in POSIX.1-2008, and was a GNU extension before that. Therefore we can't rely on it, but can fall back to the existing getc loop when it is not available. The HAVE_GETDELIM knob is turned on automatically for Linux, where we have glibc. We don't need to set any new feature-test macros, because we already define _GNU_SOURCE. Other systems that implement getdelim may need to other macros (probably _POSIX_C_SOURCE >= 200809L), but we can address that along with setting the Makefile knob after testing the feature on those systems. Running "git rev-parse refs/heads/does-not-exist" on a repo with an extremely large (1.6GB) packed-refs file went from (best-of-5): real 0m8.601s user 0m8.084s sys 0m0.524s to: real 0m6.768s user 0m6.340s sys 0m0.432s for a wall-clock speedup of 21%.

The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

Move xstrdup from env_setenv to make_augmented_environ, so that mingw_putenv no longer copies the environment entries (according to POSIX [1], "the string [...] shall become part of the environment"). This also fixes the memory leak in gitsetenv, which expects a POSIX compliant putenv.

To simplify adaption to different platforms, split the implementation into a common getnanotime() and a platform-specific highres_nanos() function. The common getnanotime() function handles errors, falling back to gettimeofday() if highres_nanos() isn't implemented or doesn't work. getnanotime() is also responsible for normalizing to the epoch. The offset to the system clock is calculated only once on initialization, i.e. manually setting the system clock has no impact on the timer (except if the fallback gettimeofday() is in use). Git processes are typically short lived, so we don't need to handle clock drift. The highres_nanos() function returns monotonically increasing nanoseconds relative to some arbitrary point in time (e.g. system boot), or 0 on failure. Providing platform-specific implementations should be relatively easy, e.g. adapting to clock_gettime() as defined by the POSIX realtime extensions is seven lines of code. This version includes highres_nanos() implementations for: * Linux: using clock_gettime(CLOCK_MONOTONIC) * Windows: using QueryPerformanceCounter() Todo: * enable clock_gettime() on more platforms * add Mac OSX version, e.g. using mach_absolute_time + mach_timebase_info Signed-off-by: NKarsten Blees <blees@dcon.de> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

There are no proper inodes on Windows, so remove dirent.d_ino and #define NO_D_INO_IN_DIRENT in the Makefile (this skips e.g. an ineffective qsort in fsck.c).

Dynamic linking is generally preferred over static linking, and MSVCRT.dll has been integral part of Windows for a long time. This also fixes linker warnings for _malloc and _free in zlib.lib, which seems to be compiled for MSVCRT.dll already. The DLL version also exports some of the CRT initialization functions, which are hidden in the static libcmt.lib (e.g. __wgetmainargs, required by subsequent Unicode patches).

Multi-threaing of index-pack was disabled with c0f86547 (index-pack: Disable threading on cygwin - 2012-06-26), because pread() implementations for Cygwin and MSYS were not thread safe. Recent Cygwin does offer usable pread() and we enabled multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread, 2013-07-19). Work around this problem on platforms with a thread-unsafe pread() emulation by opening one file handle per thread; it would prevent parallel pread() on different file handles from stepping on each other. Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f86547 because it's no longer used anywhere. This workaround is unconditional, even for platforms with thread-safe pread() because the overhead is small (a couple file handles more) and not worth fragmenting the code.

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.

Most gmtime implementations return a NULL value when they encounter an error (and this behavior is specified by ANSI C and POSIX). FreeBSD's implementation, however, will simply leave the "struct tm" untouched. Let's also recognize this and convert it to a NULL (with this patch, t4212 should pass on FreeBSD).

By default, Windows abort()'s instead of setting errno=EINVAL when invalid arguments are passed to standard functions. For example, when PAGER quits and git detects it with errno=EPIPE on write(), check_pipe() in write_or_die.c tries raise(SIGPIPE) but since there is no SIGPIPE on Windows, it is treated as invalid argument, causing abort() and crash report window. Linking in invalidcontinue.obj (provided along with MS compiler) allows raise(SIGPIPE) to return with errno=EINVAL.
