Checking the work tree status is quite slow on Windows, due to slow
`lstat()` emulation (git calls `lstat()` once for each file in the
index). Windows operating system APIs seem to be much better at scanning
the status of entire directories than checking single files.
Add an `lstat()` implementation that uses a cache for lstat data. Cache
misses read the entire parent directory and add it to the cache.
Subsequent `lstat()` calls for the same directory are served directly
from the cache.
Also implement `opendir()`/`readdir()`/`closedir()` so that they create
and use directory listings in the cache.
The cache doesn't track file system changes and doesn't plug into any
modifying file APIs, so it has to be explicitly enabled for git functions
that don't modify the working copy.
Note: in an earlier version of this patch, the cache was always active and
tracked file system changes via ReadDirectoryChangesW. However, this was
much more complex and had negative impact on the performance of modifying
git commands such as 'git checkout'.

winuser.h contains the definition of RT_MANIFEST that our LLVM based
toolchain needs to understand that we want to embed
compat/win32/git.manifest as an application manifest. It currently just
embeds it as additional data that Windows doesn't understand.
This also helps our GCC based toolchain understand that we only want one
copy embedded. It currently embeds one working assembly manifest and one
nearly identical, but useless copy as additional data.
This also teaches our Visual Studio based buildsystems to pick up the
manifest file from git.rc. This means we don't have to explicitly specify
it in contrib/buildsystems/Generators/Vcxproj.pm anymore. Slightly
counter-intuitively this also means we have to explicitly tell Cmake
not to embed a default manifest.

Ensure key CMake option values are part of the CMake output to

Git's regular Makefile mentions that HOST_CPU should be defined when cross-compiling Git: 37796bca76/Makefile (L438-L439)
This is then used to set the GIT_HOST_CPU variable when compiling Git: 37796bca76/Makefile (L1337-L1341)
Then, when the user runs `git version --build-options`, it returns that value: 37796bca76/help.c (L658)

In Git-for-Windows, work on using ARM64 has progressed. The
commit 2d94b77b27 (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 635b6d99b3 (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.

Before we had CMake support, the only way to build Git in Visual Studio
was via this hacky `generate` script.
For a while I tried to fix whenever things got broken, in particular to
allow building confidence in embargoed releases by running the CI builds
in Azure Pipelines in a private Azure DevOps project. I even carried the
patches in Git for Windows with the intention of upstreaming them,
eventually.
However, it is a lot of work with too little benefit. CMake is much
better supported by Visual Studio. So let's drop this hacky script (plus

Building our "gitweb" interface is optional in our Makefile and in Meson
and not wired up at all with CMake, but disabling it causes a couple of
tests in the t950* range that pull in "t/lib-gitweb.sh". This is because
the test library knows to execute gitweb-tests based on whether or not
Perl is available, but we may have Perl available and still end up not
building gitweb e.g. with `make test NO_GITWEB=YesPlease`.
Fix this issue by wiring up a new "NO_GITWEB" build option so that we
can skip these tests in case gitweb is not built.
Note that this new build option requires us to move the configuration of
GIT-BUILD-OPTIONS to a later point in our Meson build instructions. But
as that file is only consumed by our tests at runtime this change does
not cause any issues.

When the `vcxproj` target was introduced in `config.mak.uname` to allow
building Git with the Visual C toolchain, the `git remote-ext` command
was always executed in its dashed form. Therefore, it was impossible to
pass the test suite unless that command existed in its dashed form, and
we had to special-case this.
Later, when the `vcxproj` target got out of fashion because Visual
Studio gained native support for CMake builds, this special-casing was
copied without questioning it.
But as of 675df192c5 (transport-helper: do not run git-remote-ext etc.
in dashed form, 2020-08-26), the reason for this special-casing no
longer exists. So let's just drop it.

shell script to transform the files) was replaced by the same
`generate-perl.sh` invocation as for the Makefile-based build.
The only difference is that now the transformation tries to handle the
Perl modules in-place (which ends up in empty files because the same

Perl script cannot find them anymore because they are not in the

hard-code the directory where it expects to find the merge tools to
hard-coding that value in the placeholder `@GIT_TEST_MERGE_TOOLS_DIR@`

Introduce support for the Meson build system, a "modern" meta build
system that supports many different platforms, including Linux, macOS,
Windows and BSDs. Meson supports different backends, including Ninja,
Xcode and Microsoft Visual Studio. Several common IDEs provide an
integration with it.
The biggest contender compared to Meson is probably CMake as outlined in
our "Documentation/technical/build-systems.txt" file. Based on my own
personal experience from working with both build systems extensively I
strongly favor Meson over CMake. In my opinion, it feels significantly
easier to use with a syntax that feels more like a "real" programming
language. The second big reason is that Meson supports Rust natively,
which may prove to be important given that the project may pick up Rust
as another language eventually.
Using Meson is rather straight-forward. An example:
```
# Meson uses out-of-tree builds. You can set up multiple build
# directories, how you name them is completely up to you.
$ mkdir build
$ cd build
$ meson setup .. -Dprefix=/tmp/git-installation
# Build the project. This also provides several other targets like
e.g. `install` or `test`.
$ ninja
# Meson has been wired up to support execution of our test suites.
# Both our unit tests and our integration tests are supported.
# Running `meson test` without any arguments will execute all tests,
# but the syntax supports globbing to select only some tests.
$ meson test 't-*'
# Execute single test interactively to allow for debugging.
$ meson test 't0000-*' --interactive --test-args=-ix
```
The build instructions have been successfully tested on the following
systems, tests are passing:
- Apple macOS 10.15.
- FreeBSD 14.1.
- NixOS 24.11.
- OpenBSD 7.6.
- Ubuntu 24.04.
- Windows 10 with Cygwin.
- Windows 10 with MinGW64, except for t9700, which is also broken with
our Makefile.
- Windows 10 with Visual Studio 2022 toolchain, using the Native Tools
Command Prompt with `meson setup --vsenv`. Tests pass, except for
t9700.
- Windows 10 with Visual Studio 2022 solution, using the Native Tools
Command Prompt with `meson setup --backend vs2022`. Tests pass,
except for t9700.
- Windows 10 with VS Code, using the Meson plug-in.
It is expected that there will still be rough edges in the current
version. If this patch lands the expectation is that it will coexist
with our other build systems for a while. Like this, distributions can
slowly migrate over to Meson and report any findings they have to us
such that we can continue to iterate. A potential cutoff date for other
build systems may be Git 3.0.
Some notes:
- The installed distribution is structured somewhat differently than
how it used to be the case. All of our binaries are installed into
`$libexec/git-core`, while all binaries part of `$bindir` are now
symbolic links pointing to the former. This rule is consistent in
itself and thus easier to reason about.
- We do not install dashed binaries into `$libexec/git-core` anymore,
so there won't e.g. be a symlink for git-add(1). These are not
required by modern Git and there isn't really much of a use case for
those anymore. By not installing those symlinks we thus start the
deprecation of this layout.
- We're targeting Meson 1.3.0, which has been released relatively
recently November 2023. The only feature we use from that version is
`fs.relative_to()`, which we could replace if necessary. If so, we
could start to target Meson 1.0.0 and newer, released in December
2022.
- The whole build instructions count around 3300 lines, half of which
is listing all of our code and test files. Our Makefiles are around
5000 lines, autoconf adds another 1300 lines. CMake in comparison
has only 1200 linescode, but it avoids listing individual files and
does not wire up auto-configuration as extensively as the Meson
instructions do.
- We bundle a set of subproject wrappers for curl, expat, openssl,
pcre2 and zlib. This allows developers to build Git without these
dependencies preinstalled, and Meson will fetch and build them
automatically. This is especially helpful on Windows.

Our in-tree builds used by the Makefile use various different build
directories scattered around different locations. The paths to those
build directories have to be propagated to our tests such that they can
find the contained files. This is done via a mixture of hardcoded paths
in our test library and injected variables in our bin-wrappers or
"GIT-BUILD-OPTIONS".
The latter two mechanisms are preferable over using hardcoded paths. For
one, we have all paths which are subject to change stored in a small set
of central files instead of having the knowledge of build paths in many
files. And second, it allows build systems which build files elsewhere
to adapt those paths based on their own needs. This is especially nice
in the context of build systems that use out-of-tree builds like CMake
or Meson.
Remove hardcoded knowledge of build paths from our test library and move
it into our bin-wrappers and "GIT-BUILD-OPTIONS".

When we install Git we also install a set of default templates that both
git-init(1) and git-clone(1) populate into our build directories. The
way the pristine templates are laid out in our source directory is
somewhat weird though: instead of reconstructing the actual directory
hierarchy in "templates/", we represent directory separators with "--".
The only reason I could come up with for why we have this is the
"branches/" directory, which is supposed to be empty when installing it.
And as Git famously doesn't store empty directories at all we have to
work around this limitation.
Now the thing is that the "branches/" directory is a leftover to how
branches used to be stored in the dark ages. gitrepository-layout(5)
lists this directory as "slightly deprecated", which I would claim is a
strong understatement. I have never encountered anybody using it today
and would be surprised if it even works as expected. So having the "--"
hack in place for an item that is basically unused, unmaintained and
deprecated doesn't only feel unreasonable, but installing that entry by
default may also cause confusion for users that do not know what this is
supposed to be in the first place.
Remove this directory from our templates and, now that we do not require
the workaround anymore, restructure the templates to form a proper
hierarchy. This makes it way easier for build systems to install these
templates into place.
We should likely think about removing support for "branch/" altogether,
but that is outside of the scope of this patch series.

arbitrary input file. This allows us to simplify the logic in CMake to

We have a bunch of placeholders in our scripts that we replace at build

Next to being inconsistent it also creates a bit of a problem with
CMake, which only supports the first syntax in its `configure_file()`
function. To work around that we instead manually replace placeholders
via string operations, which is a hassle and removes safeguards that
CMake has to verify that we didn't forget to replace any placeholders.

The "GIT-BUILD-OPTIONS" file is generated by our build systems to
propagate built-in features and paths to our tests. The generation is
done ad-hoc, where both our Makefile and the CMake build instructions
simply echo a bunch of strings into the file. This makes it very hard to
figure out what variables are expected to exist and what format they
have, and the written variables can easily get out of sync between build
systems.
Introduce a new "GIT-BUILD-OPTIONS.in" template to address this issue.
This has multiple advantages:
- It demonstrates which built options exist in the first place.
- It can serve as a spot to document the build options.
- Some build systems complain when not all variables could be
substituted, alerting us of mismatches. Others don't, but if we
forgot to substitute such variables we now have a bogus string that
will likely cause our tests to fail, if they have any meaning in the
first place.

it has been set up via the environment. This is the only instance I

Buildfix and upgrade of Clar to a newer version.
* ps/upgrade-clar:
cmake: set up proper dependencies for generated clar headers
cmake: fix compilation of clar-based unit tests
Makefile: extract script to generate clar declarations
Makefile: adjust sed command for generating "clar-decls.h"
t/unit-tests: update clar to 206accb
Various platform compatibility fixes split out of the larger effort
to use Meson as the primary build tool.

t6006: fix prereq handling with `test_format ()`
http: fix build error on FreeBSD
builtin/credential-cache: fix missing parameter for stub function
t7300: work around platform-specific behaviour with long paths on MinGW
t5500, t5601: skip tests which exercise paths with '[::1]' on Cygwin
t3404: work around platform-specific behaviour on macOS 10.15
t1401: make invocation of tar(1) work with Win32-provided one
t/lib-gpg: fix setup of GNUPGHOME in MinGW
t/lib-gitweb: test against the build version of gitweb
t/test-lib: wire up NO_ICONV prerequisite
t/test-lib: fix quoting of TEST_RESULTS_SAN_FILE
Our platform support policy states that we require "versions of
dependencies which are generally accepted as stable and supportable,
e.g., in line with the version used by other long-term-support
distributions". Of Debian, Ubuntu, RHEL, and SLES, the four most common
distributions that provide LTS versions, the version with mainstream
long-term security support with the oldest Perl is 5.26.0 in SLES 15.6.
This is a major upgrade, since Perl 5.8.1, according to the Perl
documentation, was released in September of 2003. It brings a lot of
new features that we can choose to use, such as s///r to return the
modified string, the postderef functionality, and subroutine signatures,
although the latter was still considered experimental until 5.36.
This change was made with the following one-liner, which intentionally
excludes modifying the vendored modules we include to avoid conflicts:
git grep -l 'use 5.008001' | grep -v 'LoadCPAN/' | xargs perl -pi -e 's/use 5.008001/require v5.26/'
Use require instead of use to avoid changing the behavior as the latter
enables features and the former does not.

The auto-generated headers used by clar are written at configure time
and thus do not get regenerated automatically. Refactor the build
recipes such that we use custom commands instead, which also has the
benefit that we can reuse the same infrastructure as our Makefile.
