Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

# Platform specific Makefile tweaks based on uname detection
msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

Makefile: restrict -Wpedantic and -Wno-pedantic-ms-format better 6a8cbc41ba (developer: enable pedantic by default, 2021-09-03) enables pedantic mode in as many compilers as possible to help gather feedback on future tightening, so lets do so. -Wpedantic is missing in some really old gcc 4 versions so lets restrict it to gcc5 and clang4 (it does work in clang3 AFAIK, but it will be unlikely that a developer will use such an old compiler anyway). MinGW gcc is the only one which has -Wno-pedantic-ms-format, and while that is available also in older compilers, the Windows SDK provides gcc10 so lets aim for that. Note that in order to target the flag to only Windows, additional changes were needed in config.mak.uname to propagate the OS detection which also did some minor refactoring, but which is functionaly equivalent.

msvc: add a Makefile target to pre-generate the Visual Studio solution The entire idea of generating the VS solution makes only sense if we generate it via Continuous Integration; otherwise potential users would still have to download the entire Git for Windows SDK. If we pre-generate the Visual Studio solution, Git can be built entirely within Visual Studio, and the test scripts can be run in a regular Git for Windows (e.g. the Portable Git flavor, which does not include a full GCC toolchain and therefore weighs only about a tenth of Git for Windows' SDK). So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash after building the solution in Visual Studio. Note: for this build target, we do not actually need to initialize the `vcpkg` system, so we don't.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

trace: add high resolution timer function to debug performance issues Add a getnanotime() function that returns nanoseconds since 01/01/1970 as unsigned 64-bit integer (i.e. overflows in july 2554). This is easier to work with than e.g. struct timeval or struct timespec. Basing the timer on the epoch allows using the results with other time-related APIs. 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: Karsten Blees <blees@dcon.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

core.fsyncmethod: add writeout-only mode 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.

strbuf_getwholeline: use getdelim if it is available 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.

gc --auto: exclude base pack if not enough mem to "repack -ad" pack-objects could be a big memory hog especially on large repos, everybody knows that. The suggestion to stick a .keep file on the giant base pack to avoid this problem is also known for a long time. Recent patches add an option to do just this, but it has to be either configured or activated manually. This patch lets `git gc --auto` activate this mode automatically when it thinks `repack -ad` will use a lot of memory and start affecting the system due to swapping or flushing OS cache. gc --auto decides to do this based on an estimation of pack-objects memory usage, which is quite accurate at least for the heap part, and whether that fits in half of system memory (the assumption here is for desktop environment where there are many other applications running). This mechanism only kicks in if gc.bigBasePackThreshold is not configured. If it is, it is assumed that the user already knows what they want.

This is used to enable RUNTIME_PREFIX support for non-Windows systems, notably Linux and Darwin.

tr2: log parent process name 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.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

config.mak.uname: Darwin: define HAVE_GETDELIM for modern OS X releases 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().

read-cache: optionally disallow HFS+ .git variants 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 HFS+; 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 HFS+. 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.protectHFS config option. Though this is expected to be most useful on OS X, we allow it to be set everywhere, as HFS+ may be mounted on other platforms. The variable does default to on for OS X, though.

wrapper: add a helper to generate numbers from a CSPRNG 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.

macOS/brew: let the build find gettext headers/libraries/msgfmt Apparently a recent Homebrew update now installs `gettext` into the subdirectory /usr/local/opt/gettext/[lib/include].

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.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

packed_ref_cache: keep the `packed-refs` file mmapped if possible Keep a copy of the `packed-refs` file contents in memory for as long as a `packed_ref_cache` object is in use: * If the system allows it, keep the `packed-refs` file mmapped. * If not (either because the system doesn't support `mmap()` at all, or because a file that is currently mmapped cannot be replaced via `rename()`), then make a copy of the file's contents in heap-allocated space, and keep that around instead. We base the choice of behavior on a new build-time switch, `MMAP_PREVENTS_DELETE`. By default, this switch is set for Windows variants. After this commit, `MMAP_NONE` and `MMAP_TEMPORARY` are still handled identically. But the next commit will introduce a difference. This whole change is still pointless, because we only read the `packed-refs` file contents immediately after instantiating the `packed_ref_cache`. But that will soon change.

git clone <url> C:\cygwin\home\USER\repo' is working (again) 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.

wrapper: add a helper to generate numbers from a CSPRNG 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.

config.mak.uname: set FREAD_READS_DIRECTORIES for Linux and FreeBSD This variable is added [1] with the assumption that on a sane system, fopen(<dir>, "r") should return NULL. Linux and FreeBSD do not meet this expectation while at least Windows and AIX do. Let's make sure they behave the same way. I only tested one version on Linux (4.7.0 with glibc 2.22) and FreeBSD (11.0) but since GNU/kFreeBSD is fbsd kernel with gnu userspace, I'm pretty sure it shares the same problem.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

wrapper: add a helper to generate numbers from a CSPRNG 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.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak.

This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs.

But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy.

wrapper: add a helper to generate numbers from a CSPRNG 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.

We base the choice of behavior on a new build-time switch, `MMAP_PREVENTS_DELETE`. By default, this switch is set for Windows variants.

Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

msvc: avoid collisions between "tags" and "TAGS" Commit 2f769195 ("MinGW: avoid collisions between "tags" and "TAGS", 28-09-2010) enabled MinGW to use an ETAGS file in order to avoid filename collisions on (Windows) case insensitive filesystems. In addition, this prevents 'make' from issuing several warning messages. When using the Makefile to perform an MSVC build, which is usually executed using MinGW tools, we can also benefit from this capability. In order to reap the above benefits, we set the ETAGS_TARGET build variable to ETAGS in the MSVC config block.

mingw: move Git for Windows' system config where users expect it 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.

msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

core.fsyncmethod: add writeout-only mode 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.

mingw: replace mingw_startup() hack Git for Windows has special code to retrieve the command-line parameters (and even the environment) in UTF-16 encoding, so that they can be converted to UTF-8. This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any compiler other than GCC, and in preparation for compiling with Visual C++, we would like to avoid precisely that. Lucky us, there is a much more elegant way: we can simply implement the UTF-16 variant of `main()`: `wmain()`. To make that work, we need to link with -municode. The command-line parameters are passed to `wmain()` encoded in UTF-16, as desired, and this method also works with GCC, and also with Visual C++ after adjusting the MSVC linker flags to force it to use `wmain()`.

msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

wrapper: add a helper to generate numbers from a CSPRNG 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.

Makefile: restrict -Wpedantic and -Wno-pedantic-ms-format better 6a8cbc41ba (developer: enable pedantic by default, 2021-09-03) enables pedantic mode in as many compilers as possible to help gather feedback on future tightening, so lets do so. -Wpedantic is missing in some really old gcc 4 versions so lets restrict it to gcc5 and clang4 (it does work in clang3 AFAIK, but it will be unlikely that a developer will use such an old compiler anyway). MinGW gcc is the only one which has -Wno-pedantic-ms-format, and while that is available also in older compilers, the Windows SDK provides gcc10 so lets aim for that. Note that in order to target the flag to only Windows, additional changes were needed in config.mak.uname to propagate the OS detection which also did some minor refactoring, but which is functionaly equivalent.

tr2: make process info collection platform-generic 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.

wrapper: add a helper to generate numbers from a CSPRNG 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.

mingw: replace mingw_startup() hack Git for Windows has special code to retrieve the command-line parameters (and even the environment) in UTF-16 encoding, so that they can be converted to UTF-8. This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any compiler other than GCC, and in preparation for compiling with Visual C++, we would like to avoid precisely that. Lucky us, there is a much more elegant way: we can simply implement the UTF-16 variant of `main()`: `wmain()`. To make that work, we need to link with -municode. The command-line parameters are passed to `wmain()` encoded in UTF-16, as desired, and this method also works with GCC, and also with Visual C++ after adjusting the MSVC linker flags to force it to use `wmain()`.

core.fsyncmethod: add writeout-only mode 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.

git clone <url> C:\cygwin\home\USER\repo' is working (again) 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.

Define NO_GETTEXT for Git for Windows The dreaded "your vnsprintf is broken (returned -1)" error is back. At least with the libintl version we have. So for the moment, just work around the issue by _not_ using gettext. Ah, I wish that my attempt at implementing a custom strbuf_vaddf() would not have been brushed aside so rashly. Oh well. Time saved on maintaining that thing, I guess (although more time went into working around coping with existing implementations). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

mingw: fix a typo in the msysGit-specific section The msysGit project (i.e. Git for Windows 1.x' SDK) is safely dead for *years* already. This is probably the reason why nobody caught this typo until Carlo Arenas spotted a copy-edited version of it nearby.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings.

mingw: allow building with an MSYS2 runtime v3.x Recently the Git for Windows project started the upgrade process to a MSYS2 runtime version based on Cygwin v3.x. This has the very notable consequence that `$(uname -r)` no longer reports a version starting with "2", but a version with "3". That breaks our build, as df5218b4c30b (config.mak.uname: support MSys2, 2016-01-13) simply did not expect the version reported by `uname -r` to depend on the underlying Cygwin version: it expected the reported version to match the "2" in "MSYS2". So let's invert that test case to test for *anything else* than a version starting with "1" (for MSys). That should safeguard us for the future, even if Cygwin ends up releasing versionsl like 314.272.65536.

config.mak.uname: support MSys2 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.

mingw: enable DEP and ASLR Enable DEP (Data Execution Prevention) and ASLR (Address Space Layout Randomization) support. This applies to both 32bit and 64bit builds and makes it substantially harder to exploit security holes in Git by offering a much more unpredictable attack surface. ASLR interferes with GDB's ability to set breakpoints. A similar issue holds true when compiling with -O2 (in which case single-stepping is messed up because GDB cannot map the code back to the original source code properly). Therefore we simply enable ASLR only when an optimization flag is present in the CFLAGS, using it as an indicator that the developer does not want to debug in GDB anyway.

To remove yet another attack vector, let's make use of gcc's stack smashing protector that helps detect stack buffer overruns early. Rather than using -fstack-protector, we use -fstack-protector-strong because on Windows: The latter appears to strike a better balance between the performance impact and the provided safety. In a non-scientific test (time git log --grep=is -p), best of 5 timings went from 23.009s to 22.997s, i.e. the performance impact was *well* lost in the noise.

mingw: move Git for Windows' system config where users expect it 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.

config.mak.uname: support MSys2 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.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

msvc: add a Makefile target to pre-generate the Visual Studio solution The entire idea of generating the VS solution makes only sense if we generate it via Continuous Integration; otherwise potential users would still have to download the entire Git for Windows SDK. If we pre-generate the Visual Studio solution, Git can be built entirely within Visual Studio, and the test scripts can be run in a regular Git for Windows (e.g. the Portable Git flavor, which does not include a full GCC toolchain and therefore weighs only about a tenth of Git for Windows' SDK). So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash after building the solution in Visual Studio. Note: for this build target, we do not actually need to initialize the `vcpkg` system, so we don't.

Makefile: stop hardcoding {command,config}-list.h Change various places that hardcode the names of these two files to refer to either $(GENERATED_H), or to a new generated-hdrs target. That target is consistent with the *-objs targets I recently added in 029bac01a8 (Makefile: add {program,xdiff,test,git,fuzz}-objs & objects targets, 2021-02-23). A subsequent commit will add a new generated hook-list.h. By doing this refactoring we'll only need to add the new file to the GENERATED_H variable, not EXCEPT_HDRS, the vcbuild/README etc. Hardcoding command-list.h there seems to have been a case of copy/paste programming in 976aaedca0 (msvc: add a Makefile target to pre-generate the Visual Studio solution, 2019-07-29).
