Git's regular Makefile mentions that HOST_CPU should be defined when cross-compiling Git: https://github.com/git-for-windows/git/blob/37796bca76ef4180c39ee508ca3e42c0777ba444/Makefile#L438-L439 This is then used to set the GIT_HOST_CPU variable when compiling Git: https://github.com/git-for-windows/git/blob/37796bca76ef4180c39ee508ca3e42c0777ba444/Makefile#L1337-L1341 Then, when the user runs `git version --build-options`, it returns that value: https://github.com/git-for-windows/git/blob/37796bca76ef4180c39ee508ca3e42c0777ba444/help.c#L658 This commit adds the same functionality to the CMake configuration.

As reported in newren/git-filter-repo#225, it looks like 99 bytes is not really sufficient to represent e.g. the full path to Python when installed via Windows Store (and this path is used in the hasb bang line when installing scripts via `pip`). Let's increase it to what is probably the maximum sensible path size: MAX_PATH. This makes `parse_interpreter()` in line with what `lookup_prog()` handles.

We used to have that `make vcxproj` hack, but a hack it is. In the meantime, we have a much cleaner solution: using CMake, either explicitly, or even more conveniently via Visual Studio's built-in CMake support (simply open Git's top-level directory via File>Open>Folder...). Let's let the `README` reflect this. Signed-off-by: Johannes Schindelin <[email protected]>
This adds support for a new http.sslAutoClientCert config value. In cURL 7.77 or later the schannel backend does not automatically send client certificates from the Windows Certificate Store anymore. This config value is only used if http.sslBackend is set to "schannel", and can be used to opt in to the old behavior and force cURL to send client certificates.

Because `git subtree` (unlike most other `contrib` modules) is included as part of the standard release of Git for Windows, its stability should be verified as consistently as it is for the rest of git. By including the `git subtree` tests in the CI workflow, these tests are as much of a gate to merging and indicator of stability as the standard test suite.

On LLP64 systems, such as Windows, the size of `long`, `int`, etc. is only 32 bits (for backward compatibility). Git's use of `unsigned long` for file memory sizes in many places, rather than size_t, limits the handling of large files on LLP64 systems (commonly given as `>4GB`). Provide a minimum test for handling a >4GB file. The `hash-object` command, with the `--literally` and without `-w` option avoids writing the object, either loose or packed. This avoids the code paths hitting the `bigFileThreshold` config test code, the zlib code, and the pack code. Subsequent patches will walk the test's call chain, converting types to `size_t` (which is larger in LLP64 data models) where appropriate.

The previous commit adds a test that demonstrates a problem in the `hash-object --literally` command, manifesting in an unnecessary file size limit on systems using the LLP64 data model (which includes Windows). Walking the affected code path is `cmd_hash_object()` >> `hash_fd()` >> `hash_literally()` >> `hash_object_file_literally()`. The function `hash_object_file_literally()` is the first with a file length parameter (via a mem buffer). This commit changes the type of that parameter to the LLP64 compatible `size_t` type. There are no other uses of the function. The `strbuf` type is already `size_t` compatible. Note: The hash-object test does not yet pass. Subsequent commits will continue to walk the call tree's lower level functions to identify further fixes.

Correct some wording and inform users regarding the Visual Studio changes (from V16.6) to the default generator. Subsequent commits ensure that Git for Windows can be directly opened in modern Visual Studio without needing special configuration of the CMakeLists settings. It appeares that internally Visual Studio creates it's own version of the .sln file (etc.) for extension tools that expect them. The large number of references below document the shifting of Visual Studio default and CMake setting options. refs: https://docs.microsoft.com/en-us/search/?scope=C%2B%2B&view=msvc-150&terms=Ninja 1. https://docs.microsoft.com/en-us/cpp/linux/cmake-linux-configure?view=msvc-160 (note the linux bit) "In Visual Studio 2019 version 16.6 or later ***, Ninja is the default generator for configurations targeting a remote system or WSL.

Continue walking the code path for the >4GB `hash-object --literally` test. The `hash_object_file_literally()` function internally uses both `hash_object_file()` and `write_object_file_prepare()`. Both function signatures use `unsigned long` rather than `size_t` for the mem buffer sizes. Use `size_t` instead, for LLP64 compatibility. While at it, convert those function's object's header buffer length to `size_t` for consistency. The value is already upcast to `uintmax_t` for print format compatibility. Note: The hash-object test still does not pass. A subsequent commit continues to walk the call tree's lower level hash functions to identify further fixes.

Continue walking the code path for the >4GB `hash-object --literally`
test to the hash algorithm step for LLP64 systems.
This patch lets the SHA1DC code use `size_t`, making it compatible with
LLP64 data models (as used e.g. by Windows).
The interested reader of this patch will note that we adjust the
signature of the `git_SHA1DCUpdate()` function without updating _any_
call site. This certainly puzzled at least one reviewer already, so here
is an explanation:
This function is never called directly, but always via the macro
`platform_SHA1_Update`, which is usually called via the macro
`git_SHA1_Update`. However, we never call `git_SHA1_Update()` directly
in `struct git_hash_algo`. Instead, we call `git_hash_sha1_update()`,
which is defined thusly:
static void git_hash_sha1_update(git_hash_ctx *ctx,
const void *data, size_t len)
{
git_SHA1_Update(&ctx->sha1, data, len);
}
i.e. it contains an implicit downcast from `size_t` to `unsigned long`
(before this here patch). With this patch, there is no downcast anymore.
With this patch, finally, the t1007-hash-object.sh "files over 4GB hash
literally" test case is fixed.

In Git-for-Windows, work on using ARM64 has progressed. The commit 2d94b77 (cmake: allow building for Windows/ARM64, 2020-12-04) failed to notice that /compat/vcbuild/vcpkg_install.bat will default to using the "x64-windows" architecture for the vcpkg installation if not set, but CMake is not told of this default. Commit 635b6d9 (vcbuild: install ARM64 dependencies when building ARM64 binaries, 2020-01-31) later updated vcpkg_install.bat to accept an arch (%1) parameter, but retained the default. This default is neccessary for the use case where the project directory is opened directly in Visual Studio, which will find and build a CMakeLists.txt file without any parameters, thus expecting use of the default setting. Also Visual studio will generate internal .sln solution and .vcxproj project files needed for some extension tools. Inform users of the additional .sln/.vcxproj generation. ** How to test: rm -rf '.vs' # remove old visual studio settings rm -rf 'compat/vcbuild/vcpkg' # remove any vcpkg downloads rm -rf 'contrib/buildsystems/out' # remove builds & CMake artifacts with a fresh Visual Studio Community Edition, File>>Open>>(git *folder*) to load the project (which will take some time!). check for successful compilation.

Just like the `hash-object --literally` code path, the `--stdin` code path also needs to use `size_t` instead of `unsigned long` to represent memory sizes, otherwise it would cause problems on platforms using the LLP64 data model (such as Windows). To limit the scope of the test case, the object is explicitly not written to the object store, nor are any filters applied. The `big` file from the previous test case is reused to save setup time; To avoid relying on that side effect, it is generated if it does not exist (e.g. when running via `sh t1007-*.sh --long --run=1,41`).

Ensure key CMake option values are part of the CMake output to facilitate user support when tool updates impact the wider CMake actions, particularly ongoing 'improvements' in Visual Studio. These CMake displays perform the same function as the build-options.txt provided in the main Git for Windows. CMake is already chatty. The setting of CMAKE_EXPORT_COMPILE_COMMANDS is also reported. Include the environment's CMAKE_EXPORT_COMPILE_COMMANDS value which may have been propogated to CMake's internal value. Testing the CMAKE_EXPORT_COMPILE_COMMANDS processing can be difficult in the Visual Studio environment, as it may be cached in many places. The 'environment' may include the OS, the user shell, CMake's own environment, along with the Visual Studio presets and caches. See previous commit for arefacts that need removing for a clean test.

In Git for Windows, `has_symlinks` is set to 0 by default. Therefore, we need to parse the config setting `core.symlinks` to know if it has been set to `true`. In `git init`, we must do that before copying the templates because they might contain symbolic links. Even if the support for symbolic links on Windows has not made it to upstream Git yet, we really should make sure that all the `core.*` settings are parsed before proceeding, as they might very well change the behavior of `git init` in a way the user intended.

In the case of Git for Windows (say, in a Git Bash window) running in a Windows Subsystem for Linux (WSL) directory, the GetNamedSecurityInfoW() call in is_path_owned_By_current_side() returns an error code other than ERROR_SUCCESS. This is consistent behavior across this boundary. In these cases, the owner would always be different because the WSL owner is a different entity than the Windows user. The change here is to suppress the error message that looks like this: error: failed to get owner for '//wsl.localhost/...' (1) Before this change, this warning happens for every Git command, regardless of whether the directory is marked with safe.directory. Signed-off-by: Derrick Stolee <[email protected]>

NtQueryObject under Wine can return a success but fill out no name. In those situations, Wine will set Buffer to NULL, and set result to the sizeof(OBJECT_NAME_INFORMATION). Running a command such as echo "$(git.exe --version 2>/dev/null)" will crash due to a NULL pointer dereference when the code attempts to null terminate the buffer, although, weirdly, removing the subshell or redirecting stdout to a file will not trigger the crash. Code has been added to also check Buffer and Length to ensure the check is as robust as possible due to the current behavior being fragile at best, and could potentially change in the future This code is based on the behavior of NtQueryObject under wine and reactos.

From the documentation of said setting: This boolean will enable fsync() when writing object files. This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or Linux ext3 with "data=writeback"). The most common file system on Windows (NTFS) does not guarantee that order, therefore a sudden loss of power (or any other event causing an unclean shutdown) would cause corrupt files (i.e. files filled with NULs). Therefore we need to change the default. Note that the documentation makes it sound as if this causes really bad performance. In reality, writing loose objects is something that is done only rarely, and only a handful of files at a time. Signed-off-by: Johannes Schindelin <[email protected]>
