2023-08-09win32: add a helper to run `git.exe` without a foreground windowJohannes Schindelin
On Windows, there are two kinds of executables, console ones and non-console ones. Git's executables are all console ones. When launching the former e.g. in a scheduled task, a CMD window pops up. This is not what we want for the tasks installed via the `git maintenance` command. To work around this, let's introduce `headless-git.exe`, which is a non-console program that does _not_ pop up any window. All it does is to re-launch `git.exe`, suppressing that console window, passing through all command-line arguments as-are.

MSys has long fallen behind MSYS2 in features like Unicode or x86_64 support or even security bug fixes, and is therefore no longer used by anyone in the Git developer community. The Git for Windows project itself started switching from MSys to MSYS2 early in 2015, i.e. about eight years ago. Let's drop supporting MSys as a development platform.

nedalloc was added to fix the slowness of memory allocator. Here specifically for the MSys2 build there seems to be a duplication of USE_NED_ALLOCATOR directive. So this patch intends to remove the duplicate USE_NED_ALLOCATOR and keeping it only into the MSys2 config section so it still uses the nedalloc.

2022-07-29mingw: remove unneeded `NO_CURL` directiveJohannes Schindelin
In df5218b4c30 (config.mak.uname: support MSys2, 2016-01-13), we introduced support for building Git for Windows in the then-brand new Git for Windows v2.x build environment that was based off of MSYS2. To do that, we split the non-msysGit part (that targeted MSys1) in two, and instead of sharing the `NO_CURL = YesPlease` setting with MSys1, we overrode it for MSYS2 with the empty value because we very much want to build Git for Windows with libcurl. But that was unnecessary: we never set that variable beforehand, therefore there is no need to override it. Let's just remove that unnecessary line.

In f9206ce2681 (mingw: let's use gettext with MSYS2, 2016-01-26), we flipped the switch to build Git for Windows with support for gettext. However, the way we flipped the switch was by changing the value of the `NO_GETTEXT` variable from a non-empty string to the empty string, as if there was any `NO_GETTEXT` definition we needed to override. But that was a mistake: while there _is_ a definition, it is in the `THIS_IS_MSYSGIT` section, i.e. it does not affect the Git for Windows part at all. Let's just remove that unnecessary line.

2022-07-29windows: include the Python bits when building Git for WindowsJohannes Schindelin
While Git for Windows does not _ship_ Python (in order to save on bandwidth), MSYS2 provides very fine Python interpreters that users can easily take advantage of, by using Git for Windows within its SDK. Previously, we excluded the Python bits, mostly due to historical reasons: In the Git for Windows v1.x days, we built Git using MSys/MinGW, without support for any Python scripts. Therefore, let's move out the `NO_PYTHON` definition from the generic part of the MINGW section (which includes special handling for MSYS2/Git for Windows, for the long-superseded msysGit environment, as well as for the setup of probably just one developer remaining with their MSys1) into the two sections that cover different environments than Git for Windows' SDK.

2022-03-11core.fsyncmethod: add writeout-only modeNeeraj Singh
This commit introduces the `core.fsyncMethod` configuration knob, which can currently be set to `fsync` or `writeout-only`. The new writeout-only mode attempts to tell the operating system to flush its in-memory page cache to the storage hardware without issuing a CACHE_FLUSH command to the storage controller. Writeout-only fsync is significantly faster than a vanilla fsync on common hardware, since data is written to a disk-side cache rather than all the way to a durable medium. Later changes in this patch series will take advantage of this primitive to implement batching of hardware flushes. When git_fsync is called with FSYNC_WRITEOUT_ONLY, it may fail and the caller is expected to do an ordinary fsync as needed. On Apple platforms, the fsync system call does not issue a CACHE_FLUSH directive to the storage controller. This change updates fsync to do fcntl(F_FULLFSYNC) to make fsync actually durable. We maintain parity with existing behavior on Apple platforms by setting the default value of the new core.fsyncMethod option.

2022-01-26compat: auto-detect if zlib has uncompress2()Ævar Arnfjörð Bjarmason
We have a copy of uncompress2() implementation in compat/ so that we can build with an older version of zlib that lack the function, and the build procedure selects if it is used via the NO_UNCOMPRESS2 $(MAKE) variable. This is yet another "annoying" knob the porters need to tweak on platforms that are not common enough to have the default set in the config.mak.uname file. Attempt to instead ask the system header <zlib.h> to decide if we need the compatibility implementation. This is a deviation from the way we have been handling the "compatiblity" features so far, and if it can be done cleanly enough, it could work as a model for features that need compatibility definition we discover in the future. With that goal in mind, avoid expedient but ugly hacks, like shoving the code that is conditionally compiled into an unrelated .c file, which may not work in future cases---instead, take an approach that uses a file that is independently compiled and stands on its own. Compile and link compat/zlib-uncompress2.c file unconditionally, but conditionally hide the implementation behind #if/#endif when zlib version is 1.2.9 or newer, and unconditionally archive the resulting object file in the libgit.a to be picked up by the linker. There are a few things to note in the shape of the code base after this change: - We no longer use NO_UNCOMPRESS2 knob; if the system header <zlib.h> claims a version that is more cent than the library actually is, this would break, but it is easy to add it back when we find such a system. - The object file compat/zlib-uncompress2.o is always compiled and archived in libgit.a, just like a few other compat/ object files already are. - The inclusion of <zlib.h> is done in <git-compat-util.h>; we used to do so from <cache.h> which includes <git-compat-util.h> as the first thing it does, so from the *.c codes, there is no practical change. - Until objects in libgit.a that is already used gains a reference to the function, the reftable code will be the only one that wants it, so libgit.a on the linker command line needs to appear once more at the end to satisify the mutual dependency. - Beat found a trick used by OpenSSL to avoid making the conditionally-compiled object truly empty (apparently because they had to deal with compilers that do not want to see an effectively empty input file). Our compat/zlib-uncompress2.c file borrows the same trick for portabilty.

2022-01-18wrapper: add a helper to generate numbers from a CSPRNGbrian m. carlson
There are many situations in which having access to a cryptographically secure pseudorandom number generator (CSPRNG) is helpful. In the future, we'll encounter one of these when dealing with temporary files. To make this possible, let's add a function which reads from a system CSPRNG and returns some bytes. We know that all systems will have such an interface. A CSPRNG is required for a secure TLS or SSH implementation and a Git implementation which provided neither would be of little practical use. In addition, POSIX is set to standardize getentropy(2) in the next version, so in the (potentially distant) future we can rely on that. For systems which lack one of the other interfaces, we provide the ability to use OpenSSL's CSPRNG. OpenSSL is highly portable and functions on practically every known OS, and we know it will have access to some source of cryptographically secure randomness. We also provide support for the arc4random in libbsd for folks who would prefer to use that. Because this is a security sensitive interface, we take some precautions. We either succeed by filling the buffer completely as we requested, or we fail. We don't return partial data because the caller will almost never find that to be a useful behavior. Specify a makefile knob which users can use to specify one or more suitable CSPRNGs, and turn the multiple string options into a set of defines, since we cannot match on strings in the preprocessor. We allow multiple options to make the job of handling this in autoconf easier. The order of options is important here. On systems with arc4random, which is most of the BSDs, we use that, since, except on MirBSD and macOS, it uses ChaCha20, which is extremely fast, and sits entirely in userspace, avoiding a system call. We then prefer getrandom over getentropy, because the former has been available longer on Linux, and then OpenSSL. Finally, if none of those are available, we use /dev/urandom, because most Unix-like operating systems provide that API. We prefer options that don't involve device files when possible because those work in some restricted environments where device files may not be available. Set the configuration variables appropriately for Linux and the BSDs, including macOS, as well as Windows and NonStop. We specifically only consider versions which receive publicly available security support here. For the same reason, we don't specify getrandom(2) on Linux, because CentOS 7 doesn't support it in glibc (although its kernel does) and we don't want to resort to making syscalls. Finally, add a test helper to allow this to be tested by hand and in tests. We don't add any tests, since invoking the CSPRNG is not likely to produce interesting, reproducible results.

Remove the sane_grep() shell function in git-sh-setup. The two reasons for why it existed don't apply anymore: 1. It was added due to GNU grep supporting GREP_OPTIONS. See e1622bfcbad (Protect scripted Porcelains from GREP_OPTIONS insanity, 2009-11-23). Newer versions of GNU grep ignore that, but even on older versions its existence won't matter, none of these sane_grep() uses care about grep's output, they're merely using it to check if a string exists in a file or stream. We also don't care about the "LC_ALL=C" that "sane_grep" was using, these greps for fixed or ASCII strings will behave the same under any locale. 2. The SANE_TEXT_GREP added in 71b401032b9 (sane_grep: pass "-a" if grep accepts it, 2016-03-08) isn't needed either, none of these grep uses deal with binary data.

2021-07-22tr2: log parent process nameEmily Shaffer
It can be useful to tell who invoked Git - was it invoked manually by a user via CLI or script? By an IDE? In some cases - like 'repo' tool - we can influence the source code and set the GIT_TRACE2_PARENT_SID environment variable from the caller process. In 'repo''s case, that parent SID is manipulated to include the string "repo", which means we can positively identify when Git was invoked by 'repo' tool. However, identifying parents that way requires both that we know which tools invoke Git and that we have the ability to modify the source code of those tools. It cannot scale to keep up with the various IDEs and wrappers which use Git, most of which we don't know about. Learning which tools and wrappers invoke Git, and how, would give us insight to decide where to improve Git's usability and performance. Unfortunately, there's no cross-platform reliable way to gather the name of the parent process. If procfs is present, we can use that; otherwise we will need to discover the name another way. However, the process ID should be sufficient to look up the process name on most platforms, so that code may be shareable. Git for Windows gathers similar information and logs it as a "data_json" event. However, since "data_json" has a variable format, it is difficult to parse effectively in some languages; instead, let's pursue a dedicated "cmd_ancestry" event to record information about the ancestry of the current process and a consistent, parseable way. Git for Windows also gathers information about more than one generation of parent. In Linux further ancestry info can be gathered with procfs, but it's unwieldy to do so. In the interest of later moving Git for Windows ancestry logging to the 'cmd_ancestry' event, and in the interest of later adding more ancestry to the Linux implementation - or of adding this functionality to other platforms which have an easier time walking the process tree - let's make 'cmd_ancestry' accept an array of parentage.

To pave the way for non-Windows platforms to define trace2_collect_process_info(), reorganize the stub-or-definition schema to something which doesn't directly reference Windows. Platforms which want to collect parent process information in the future should: 1. Add an implementation to compat/ (e.g. compat/somearch/procinfo.c) 2. Add that object to COMPAT_OBJS to config.mak.uname (e.g. COMPAT_OBJS += compat/somearch/procinfo.o) 3. Define HAVE_PLATFORM_PROCINFO in config.mak.uname In the Windows case, this definition lives in compat/win32/trace2_win32_process_info.c, which is already conditionally added to COMPAT_OBJS; so let's add HAVE_PLATFORM_PROCINFO to hint to the build that compat/stub/procinfo.c should not be used.

2021-06-29mingw: move Git for Windows' system config where users expect itJohannes Schindelin
Git for Windows' prefix is `/mingw64/` (or `/mingw32/` for 32-bit versions), therefore the system config is located at the clunky location `C:\Program Files\Git\mingw64\etc\gitconfig`. This moves the system config into a more logical location: the `mingw64` part of `C:\Program Files\Git\mingw64\etc\gitconfig` never made sense, as it is a mere implementation detail. Let's skip the `mingw64` part and move this to `C:\Program Files\Git\etc\gitconfig`. Side note: in the rare (and not recommended) case a user chooses to install 32-bit Git for Windows on a 64-bit system, the path will of course be `C:\Program Files (x86)\Git\etc\gitconfig`. Background: During the Git for Windows v1.x days, the system config was located at `C:\Program Files (x86)\Git\etc\gitconfig`. With Git for Windows v2.x, it moved to `C:\Program Files\Git\mingw64\gitconfig` (or `C:\Program Files (x86)\Git\mingw32\gitconfig`). Rather than fixing it back then, we tried to introduce a "Windows-wide" config, but that never caught on. Likewise, we move the system `gitattributes` into the same directory. Obviously, we are cautious to do this only for the known install locations `/mingw64` and `/mingw32`; If anybody wants to override that while building their version of Git (e.g. via `make prefix=$HOME`), we leave the default location of the system config and gitattributes alone.

Work around platforms whose open() is reported to return EINTR (it shouldn't, as we do our signals with SA_RESTART). * jk/open-returns-eintr: config.mak.uname: enable OPEN_RETURNS_EINTR for macOS Big Sur Makefile: add OPEN_RETURNS_EINTR knob
2021-03-01config.mak.uname: enable OPEN_RETURNS_EINTR for macOS Big SurJeff King
We've had mixed reports on whether the latest release of macOS needs this Makefile knob set. In most reported cases, there's antivirus software running (which one might imagine could cause an open() call to be delayed). However, one of the (off-list) reports I've gotten indicated that it happened on an otherwise clean install of Big Sur. Since the symptom is so bad (checkout randomly fails to write several fails when the progress meter kicks in), and since the workaround is so lightweight (if we don't see EINTR, it's just an extra conditional check), let's just turn it on by default.

Code clean-up by removing a compatibility implementation of a function we no longer use. * cb/no-more-gmtime: compat: remove gmtime
2020-05-14compat: remove gmtimeCarlo Marcelo Arenas Belón
ccd469450a (date.c: switch to reentrant {gm,local}time_r, 2019-11-28) removes the only gmtime() call we had and moves to gmtime_r() which doesn't have the same portability problems. Remove the compat gmtime code since it is no longer needed, and confirm by successfull running t4212 in FreeBSD 9.3 amd64 (the oldest I could get a hold off). Further work might be needed to ensure 32bit time_t systems (like FreeBSD i386) will handle correctly the overflows tested in t4212, but that is orthogonal to this change, and it doesn't change the current behaviour as neither gmtime() or gmtime_r() will ever return NULL on those systems because time_t is unsigned.

Recent update to Homebrew used by macOS folks breaks build by moving gettext library and necessary headers. * ds/build-homebrew-gettext-fix: macOS/brew: let the build find gettext headers/libraries/msgfmt
2020-04-27macOS/brew: let the build find gettext headers/libraries/msgfmtJohannes Schindelin
Apparently a recent Homebrew update now installs `gettext` into the subdirectory /usr/local/opt/gettext/[lib/include]. Sometimes the ci job succeeds: brew link --force gettext Linking /usr/local/Cellar/gettext/0.20.1... 179 symlinks created And sometimes installing the package "gettext" with force-link fails: brew link --force gettext Warning: Refusing to link macOS provided/shadowed software: gettext If you need to have gettext first in your PATH run: echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.bash_profile (And the is not the final word either, since macOS itself says: The default interactive shell is now zsh.) Anyway, The latter requires CFLAGS to include /usr/local/opt/gettext/include and LDFLAGS to include /usr/local/opt/gettext/lib. Likewise, the `msgfmt` tool is no longer in the `PATH`. While it is unclear which change is responsible for this breakage (that most notably only occurs on CI build agents that updated very recently), https://github.com/Homebrew/homebrew-core/pull/53489 has fixed it. Nevertheless, let's work around this issue, as there are still quite a few build agents out there that need some help in this regard: we explicitly do not call `brew update` in our CI/PR builds anymore.
