PhilipOakley and others added 30 commits April 4, 2026 06:57
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.

In bf2d5d8 (Don't let ld strip relocations, 2016-01-16) (picked from
git-for-windows@6a237925bf10),
Git for Windows introduced the `-Wl,-pic-executable` flag, specifying
the exact entry point via `-e`. This required discerning between i686
and x86_64 code because the former required the symbol to be prefixed
with an underscore, the latter did not.

As per https://sourceware.org/bugzilla/show_bug.cgi?id=10865, the
specified symbols are already the default, though.

So let's drop the overly-specific definition.

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.

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.

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.

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`).

MSYS2 defines some helpful environment variables, e.g. `MSYSTEM`. There
is code in Git for Windows to ensure that that `MSYSTEM` variable is
set, hard-coding a default.

However, the existing solution jumps through hoops to reconstruct the
proper default, and is even incomplete doing so, as we found out when we
extended it to support CLANGARM64.

This is absolutely unnecessary because there is already a perfectly
valid `MSYSTEM` value we can use at build time. This is even true when
building the MINGW32 variant on a MINGW64 system because `makepkg-mingw`
will override the `MSYSTEM` value as per the `MINGW_ARCH` array.

The same is equally true for the `/mingw64`, `/mingw32` and
`/clangarm64` prefix: those values are already available via the
`MINGW_PREFIX` environment variable, and we just need to pass that
setting through.

Only when `MINGW_PREFIX` is not set (as is the case in Git for Windows'
minimal SDK, where only `MSYSTEM` is guaranteed to be set correctly), we
use as fall-back the top-level directory whose name is the down-cased
value of the `MSYSTEM` variable.

Incidentally, this also broadens the support to all the configurations
supported by the MSYS2 project, i.e. clang64 & ucrt64, too.

Note: This keeps the same, hard-coded MSYSTEM platform support for CMake
as before, but drops it for Meson (because it is unclear how Meson could
do this in a more flexible manner).

A change between versions 2.4.1 and 2.6.0 of the MSYS2 runtime modified
how Cygwin's runtime (and hence Git for Windows' MSYS2 runtime
derivative) handles locales: d16a56306d (Consolidate wctomb/mbtowc calls
for POSIX-1.2008, 2016-07-20).

An unintended side-effect is that "cold-calling" into the POSIX
emulation will start with a locale based on the current code page,
something that Git for Windows is very ill-prepared for, as it expects
to be able to pass a command-line containing non-ASCII characters to the
shell without having those characters munged.

One symptom of this behavior: when `git clone` or `git fetch` shell out
to call `git-upload-pack` with a path that contains non-ASCII
characters, the shell tried to interpret the entire command-line
(including command-line parameters) as executable path, which obviously
must fail.

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

vcpkg_install.bat to accept an arch (%1) parameter, but retained the default.

Git for Windows wants to add `git.exe` to the users' `PATH`, without
cluttering the latter with unnecessary executables such as `wish.exe`.
To that end, it invented the concept of its "Git wrapper", i.e. a tiny
executable located in `C:\Program Files\Git\cmd\git.exe` (originally a
CMD script) whose sole purpose is to set up a couple of environment
variables and then spawn the _actual_ `git.exe` (which nowadays lives in
`C:\Program Files\Git\mingw64\bin\git.exe` for 64-bit, and the obvious
equivalent for 32-bit installations).

Currently, the following environment variables are set unless already
initialized:

- `MSYSTEM`, to make sure that the MSYS2 Bash and the MSYS2 Perl
  interpreter behave as expected, and

- `PLINK_PROTOCOL`, to force PuTTY's `plink.exe` to use the SSH
  protocol instead of Telnet,

- `PATH`, to make sure that the `bin` folder in the user's home
  directory, as well as the `/mingw64/bin` and the `/usr/bin`
  directories are included. The trick here is that the `/mingw64/bin/`
  and `/usr/bin/` directories are relative to the top-level installation
  directory of Git for Windows (which the included Bash interprets as
  `/`, i.e. as the MSYS pseudo root directory).

Using the absence of `MSYSTEM` as a tell-tale, we can detect in
`git.exe` whether these environment variables have been initialized
properly. Therefore we can call `C:\Program Files\Git\mingw64\bin\git`
in-place after this change, without having to call Git through the Git
wrapper.

Obviously, above-mentioned directories must be _prepended_ to the `PATH`
variable, otherwise we risk picking up executables from unrelated Git
installations. We do that by constructing the new `PATH` value from
scratch, appending `$HOME/bin` (if `HOME` is set), then the MSYS2 system
directories, and then appending the original `PATH`.

Side note: this modification of the `PATH` variable is independent of
the modification necessary to reach the executables and scripts in
`/mingw64/libexec/git-core/`, i.e. the `GIT_EXEC_PATH`. That
modification is still performed by Git, elsewhere, long after making the
changes described above.

While we _still_ cannot simply hard-link `mingw64\bin\git.exe` to `cmd`
(because the former depends on a couple of `.dll` files that are only in
`mingw64\bin`, i.e. calling `...\cmd\git.exe` would fail to load due to
missing dependencies), at least we can now avoid that extra process of
running the Git wrapper (which then has to wait for the spawned
`git.exe` to finish) by calling `...\mingw64\bin\git.exe` directly, via
its absolute path.

Testing this is in Git's test suite tricky: we set up a "new" MSYS
pseudo-root and copy the `git.exe` file into the appropriate location,
then verify that `MSYSTEM` is set properly, and also that the `PATH` is
modified so that scripts can be found in `$HOME/bin`, `/mingw64/bin/`
and `/usr/bin/`.

The TerminateProcess() function does not actually leave the child
processes any chance to perform any cleanup operations. This is bad
insofar as Git itself expects its signal handlers to run.

A symptom is e.g. a left-behind .lock file that would not be left behind
if the same operation was run, say, on Linux.

To remedy this situation, we use an obscure trick: we inject a thread
into the process that needs to be killed and to let that thread run the
ExitProcess() function with the desired exit status. Thanks J Wyman for
describing this trick.

The advantage is that the ExitProcess() function lets the atexit
handlers run. While this is still different from what Git expects (i.e.
running a signal handler), in practice Git sets up signal handlers and
atexit handlers that call the same code to clean up after itself.

In case that the gentle method to terminate the process failed, we still
fall back to calling TerminateProcess(), but in that case we now also
make sure that processes spawned by the spawned process are terminated;
TerminateProcess() does not give the spawned process a chance to do so
itself.

Please note that this change only affects how Git for Windows tries to
terminate processes spawned by Git's own executables. Third-party
software that *calls* Git and wants to terminate it *still* need to make
sure to imitate this gentle method, otherwise this patch will not have
any effect.

version of Git and the WSL version of Git, we can make the Windows
version of Git also support reading and writing NTFS file modes
in a manner compatible with WSL.

Since this slightly slows down operations where lots of files are
created (such as an initial checkout), this feature is only enabled when
`core.WSLCompat` is set to true. Note that you also have to set
`core.fileMode=true` in repositories that have been initialized without
enabling WSL compatibility.

There are several ways to enable metadata loading for NTFS volumes
in WSL, one of which is to modify `/etc/wsl.conf` by adding:

```
[automount]
enabled = true
options = "metadata,umask=027,fmask=117"
```

And reboot WSL.

It can also be enabled temporarily by this incantation:

	$ sudo umount /mnt/c &&
	  sudo mount -t drvfs C: /mnt/c -o metadata,uid=1000,gid=1000,umask=22,fmask=111

It's important to note that this modification is compatible with, but
does not depend on WSL. The helper functions in this commit can operate
independently and functions normally on devices where WSL is not
installed or properly configured.

Previously, we did not install any handler for Ctrl+C, but now we really
want to because the MSYS2 runtime learned the trick to call the
ConsoleCtrlHandler when Ctrl+C was pressed.

With this, hitting Ctrl+C while `git log` is running will only terminate
the Git process, but not the pager. This finally matches the behavior on
Linux and on macOS.

…ITOR"

In e3f7e01 (Revert "editor: save and reset terminal after calling
EDITOR", 2021-11-22), we reverted the commit wholesale where the
terminal state would be saved and restored before/after calling an
editor.

The reverted commit was intended to fix a problem with Windows Terminal
where simply calling `vi` would cause problems afterwards.

To fix the problem addressed by the revert, but _still_ keep the problem
with Windows Terminal fixed, let's revert the revert, with a twist: we
restrict the save/restore _specifically_ to the case where `vi` (or
`vim`) is called, and do not do the same for any other editor.

This should still catch the majority of the cases, and will bridge the
time until the original patch is re-done in a way that addresses all
concerns.

The `--stdin` option was a well-established paradigm in other commands,
therefore we implemented it in `git reset` for use by Visual Studio.

Unfortunately, upstream Git decided that it is time to introduce
`--pathspec-from-file` instead.

To keep backwards-compatibility for some grace period, we therefore
reinstate the `--stdin` option on top of the `--pathspec-from-file`
option, but mark it firmly as deprecated.

Rather than using private IFTTT Applets that send mails to this
maintainer whenever a new version of a Git for Windows component was
released, let's use the power of GitHub workflows to make this process
publicly visible.

This workflow monitors the Atom/RSS feeds, and opens a ticket whenever a
new version was released.

Note: Bash sometimes releases multiple patched versions within a few
minutes of each other (i.e. 5.1p1 through 5.1p4, 5.0p15 and 5.0p16). The
MSYS2 runtime also has a similar system. We can address those patches as
a group, so we shouldn't get multiple issues about them.

Note further: We're not acting on newlib releases, OpenSSL alphas, Perl
release candidates or non-stable Perl releases. There's no need to open
issues about them.

Reintroduce the 'core.useBuiltinFSMonitor' config setting (originally added
in 0a756b2 (fsmonitor: config settings are repository-specific,
2021-03-05)) after its removal from the upstream version of FSMonitor.

Upstream, the 'core.useBuiltinFSMonitor' setting was rendered obsolete by
"overloading" the 'core.fsmonitor' setting to take a boolean value. However,
several applications (e.g., 'scalar') utilize the original config setting,
so it should be preserved for a deprecation period before complete removal:

* if 'core.fsmonitor' is a boolean, the user is correctly using the new
  config syntax; do not use 'core.useBuiltinFSMonitor'.
* if 'core.fsmonitor' is unspecified, use 'core.useBuiltinFSMonitor'.
* if 'core.fsmonitor' is a path, override and use the builtin FSMonitor if
  'core.useBuiltinFSMonitor' is 'true'; otherwise, use the FSMonitor hook
  indicated by the path.

Additionally, for this deprecation period, advise users to switch to using
'core.fsmonitor' to specify their use of the builtin FSMonitor.

This topic branch re-adds the deprecated --stdin/-z options to `git
reset`. Those patches were overridden by a different set of options in
the upstream Git project before we could propose `--stdin`.

We offered this in MinGit to applications that wanted a safer way to
pass lots of pathspecs to Git, and these applications will need to be
adjusted.

Instead of `--stdin`, `--pathspec-from-file=-` should be used, and
instead of `-z`, `--pathspec-file-nul`.

Git for Windows accepts pull requests; Core Git does not. Therefore we
need to adjust the template (because it only matches core Git's
project management style, not ours).

Also: direct Git for Windows enhancements to their contributions page,
space out the text for easy reading, and clarify that the mailing list
is plain text, not HTML.

Originally introduced as `core.useBuiltinFSMonitor` in Git for Windows
and developed, improved and stabilized there, the built-in FSMonitor
only made it into upstream Git (after unnecessarily long hemming and
hawing and throwing overly perfectionist style review sticks into the
spokes) as `core.fsmonitor = true`.

In Git for Windows, with this topic branch, we re-introduce the
now-obsolete config setting, with warnings suggesting to existing users
how to switch to the new config setting, with the intention to
ultimately drop the patch at some stage.
