git-gui: wire up support for the Meson build system
The Git project has started to wire up Meson as a build system in Git
v2.48.0. Wire up support for Meson in "git-gui" so that we can trivially
include it as a subproject in Git.
The "GITGUI_VERSION" variable is made available by generating and
including the "GIT-VERSION-FILE" file. Its value has been used in
various build steps, but in the preceding commits we have refactored
those to instead source the "GIT-VERSION-FILE" directly. As a result,
the variable is now only used in a single recipe, and this use can be
trivially replaced with sed(1).
Refactor the recipe to do so and stop including "GIT-VERSION-FILE" to
simplify the build process.
Extract script to generate the macOS app. This change allows us to reuse
the build logic with the Meson build system.
Note that as part of this change we also modify the TKEXECUTABLE
variable to track its full path. Like this we don't have to propagate
both the TKEXECUTABLE and TKFRAMEWORK variables into the script, and the
basename can be trivially computed from TKEXECUTABLE anyway.
The value of the GITGUI_SCRIPT variable is only used in a single place
as part of an sed(1) script that massages the "git-gui.sh" script.
Interestingly, this specific replacement does seem to be a no-op: we
replace "^ argv0=$$0" with " argv=$(GITGUI_SCRIPT)", which has a value
of "$$0". The result would thus be completely unchanged.
git-gui: make output of GIT-VERSION-GEN source'able
The output of GIT-VERSION-GEN can be sourced by our Makefile to make the
version available there. The output has a couple of spaces around the
equals sign, which is perfectly valid for parsing it in our Makefile.
But in subsequent steps we'll also want to source the file in a couple
of newly-introduced shell scripts, but having spaces around variable
assignments is invalid there.
Prepare for this step by dropping the spaces surrounding the equals
sign. Like this, we can easily use the same file both in our Makefile
and in shell scripts.
git-gui: prepare GIT-VERSION-GEN for out-of-tree builds
The GIT-VERSION-GEN unconditionally writes version information into the
source directory in the form of the "GIT-VERSION-FILE". We are about to
introduce the Meson build system though, which enforces out-of-tree
builds by default, and in that context we cannot continue to write
version information into the source tree.
Prepare the script for out-of-tree builds by treating the source
directory different from the output file.
git-gui: replace GIT-GUI-VARS with GIT-GUI-BUILD-OPTIONS
The GIT-GUI-VARS file is used to track whether any of our build options
has changed. Unfortunately, the format of that file does not allow us to
propagate those build options to other scripts. But as we are about to
introduce support for the Meson build system, we will extract a couple
of scripts to deduplicate core build logic across Makefiles and Meson.
With this refactoring, it will become necessary to make build options
more widely accessible.
Replace GIT-GUI-VARS with a new GIT-GUI-BUILD-OPTIONS file that is being
populated from a template. This file can easily be sourced from build
scripts in subsequent steps.

tests: prepare for a world without whatchanged
Some tests on fast-import run "git whatchanged" without even
checking the output from the command. It is tempting to remove the
calls altogether since they are not doing anything useful, but they
presumably were added there while the tests were developed to manually
sanity check which paths were touched.
Replace these calls with "git log --raw", which is a rough
equivalent in the more modern Git.
This does not remove "git whatchanged", but we no longer have to
worry about adjusting these places when we eventually do.

The "stats" directory contains a couple of scripts to do some statistics
on a repository:
- "git-common-hash" shows the longest common hash prefixes and can be
used to determine the minimum prefix length to use for object names
to be unique. The script has last been touched in 53474eb92ff
(contrib: update stats/mailmap script, 2012-12-12) and searching for
it on the internet doesn't really surface any potential use cases or
even mentions of it.
Modern Git also shouldn't really need this tool as it knows to
automatically scale printed prefixes via some heuristics.
- "mailmap.pl" performs some statistics on the number of mailmapped
commits in a repository. It has last been modified in 53474eb92ff
(contrib: update stats/mailmap script, 2012-12-12) and has since
been bitrotting. It doesn't even compile nowadays anymore:
$ perl contrib/stats/mailmap.pl
Experimental keys on scalar is now forbidden at contrib/stats/mailmap.pl line 57.
Type of arg 1 to keys must be hash or array (not hash element) at contrib/stats/mailmap.pl line 57, near "}) "

this script at all anymore.
- "packinfo.pl" takes the output from git-verify-pack(1) and performs
some pretty printing thereof. On the one hand it reformats the
output to be easier to read and provide some summaries. On the other
hand it may also print filenames of blobs.

The "git-resurrect.sh" script can be used to find traces of a branch tip
in the reflog and resurrect that branch. Despite a couple of global
cleanups, the script hasn't seen any activity since it was introduced in e1ff064e1bf (contrib git-resurrect: find traces of a branch name and
resurrect it, 2009-02-04).
Furthermore, the tool does not work with the "reftable" backend at all
as it directly reads ".git/logs/HEAD". As reflogs are stored as part of
the individual tables though that file wouldn't exist in a "reftable"-
enabled repository.
Last but not least, the tool doesn't even work unless it is explicitly
invoked via `git resurrect` as it sources "git-sh-setup". As none of our
build systems know to install this script, users thus have to go out of
their way to really make it work, which is highly unlikely.
Another source that indicates that this tool can be removed is a
question for how to restore deleted branches on StackOverflow [1]. The
top-voted answer uses git-reflog(1) directly and has received more than
3000 votes to date. While "git-resurrect.sh" is also mentioned, it only
got 16 upvotes, and comments mention the above caveat that users have to
do some manual setup to make it work.
It's thus rather clear that the tool doesn't have a lot or even any
users. Remove it.
The "persistent-https" remote helper supposedly speeds up SSL operations
by running a daemon that keeps a connection open to a remote server. It
is effectively unmaintained nowadays: the last time it received an
update was in accb613afd2 (contrib/persistent-https: use Git version for
build label, 2016-07-20) and its parent commits to make it compile with
Go 1.7+.
This Go toolchain is somewhat dated by now though and unsupported. The
oldest still-supported toolchain is Go 1.23, which was released in
August 2024. It is not possible to compile the remote helper with that
Go version anymore:
$ go version
go version go1.23.8 linux/amd64
$ make
case $(go version) in \
"go version go"1.[0-5].*) EQ=" " ;; *) EQ="=" ;; esac && \
go build -o git-remote-persistent-https \

to create a module there, run:
cd ../.. && go mod init
make: *** [Makefile:31: git-remote-persistent-https] Error 1
The problem is that modern Go toolchains require a "go.mod" file, but we
don't have any such files. This requirement exists since quite a while

anytime recent.

The "mw-to-git" directory contains tools for accessing MediaWiki via
Git. The scripts are essentially unmaintained in Git: despite a couple
of global cleanups, the last changes were a couple of security-related
issues part of 9a8606465e8 (remote-mediawiki: use "sh" to eliminate
unquoted commands, 2020-09-21) and its parents. We don't ever run any of
the tests so it is more likely than not that many of the tests have been
bitrotting, like e.g. documented in f8ab018dafc (remote-mediawiki tests:
annotate failing tests, 2020-09-21).
According to Matthieu Moy [1], one of the original developers of this
tool, it didn't receive any attention recently and there is no
motivation to keep maintaining it anymore in the community. The project
has been spun out of Git [2] and thus has a new official home, but did
not receive much attention over there, either.
As such, it seems like the MediaWiki transport helper is slowly fading
away. But given that there is a new home, it doesn't make sense to have
it as part of Git anymore only to let it rot. Remove the directory.
The "hooks" directory contains a handful of example hooks. Most of these
hooks are highly specific and haven't really received any updates over
the last couple of years, except for some global cleanups. The multimail
hook has also been removed in f74d11471fa (multimail: stop shipping a
copy, 2021-06-10) in favor of its upstream project [1].
Remove those hooks. If we want to provide examples for how to use Git
hooks we should do that as part of our documentation, for example in
githooks(5).
The "thunderbird-patch-inline" directory in "contrib/" contains a script
to send patch files via Thunderbird. This script depends on the
ExternalEditor extension [1], which seems to be effectively unmaintained
with the last update being in 2008. While the extension has eventually
been maintained in [2], that fork hasn't received any updates since
2020, either.
As such, the ExternalEditor extension does not work with modern versions
of Thunderbird anymore, and as the "thunderbird-patch-inline" script
depends on the ExternalEditor extension it likely doesn't work anymore,
either. The fact that this script hasn't been touched for the last 10
years outside of some global cleanup supports the idea that it is not
useful anymore.
The "remote-helpers" directory contains two remote helper scripts for
Mercurial and Bazaar. These scripts have since been converted into stubs
in b2c851a8e67 (Revert "Merge branch 'jc/graduate-remote-hg-bzr' (early
part)", 2014-05-20) as the helpers have been moved into their own
upstream projects [1][2].
Given that these stubs have been created more than a decade ago it is
very unlikely that anybody still tries to use them. Remove them.
The "examples" directory used to contain scripted versions of some of
our builtins. These have all been removed in 49eb8d39c78 (Remove
contrib/examples/*, 2018-03-25), but we left a note in the directory to
make it discoverable that there used to be examples.
It is unlikely that anybody still looks at these examples more than 7
years after they have been removed. Remove the note and its directory.

Remotes can be configured either via a repository's config or by using
the ".git/branches/" or ".git/remotes/" directories. Back when the new
config-based mechanism has been introduced we also introduced a helper
script that migrates from the old-style remote configuration to the new
config-based mechanism.
With the recent removal announcement for the two directories we also
started to instruct users to migrate repositories that still use these
mechanism to use config-based remotes. Notably though, the migration
path doesn't even use the migration script. Instead, git-remote(1)
itself knows how to migrate any such remote via `git remote rename`.
In fact, a full migration _cannot_ use the script as it only knows to
migrate remotes from ".git/remotes/", but not ".git/branches/". As such,
the migration path via `git remote rename` is the only feasible way to
fully migrate repositories over to the new format.
Last but not least, the script doesn't even work as-is as it sources
"git-sh-setup". For this to work it would need to be invoked either via
Git so that this script is in our PATH, users would have to manually
call it with an adjusted PATH, or distributions need to install the
script into "$prefix/libexec/git-core" with a "git-" prefix. All of
these steps are unlikely enough to underpin the claim that this script
is not used at all.
So given that:
- The script cannot perform a full migration of all deprecated remote
types.
- We don't advertise it anywhere.
- It has been basically untouched since 2007.
- It doesn't even work unless users do manual steps.
It should be safe enough to just remove it. Do so.

reftable: fix perf regression when reading blocks of unwanted type
In fd888311fbc (reftable/table: move reading block into block reader,
2025-04-07), we have refactored how reftable blocks are read so that
most of the logic is contained in the "block.c" subsystem itself. Most
importantly, the whole logic to read the data itself is now contained in
that subsystem.
This change caused a significant performance regression though when
reading blocks that aren't of the specific type one is searching for:
Benchmark 1: update-ref: create 100k refs (revision = fd888311fbc~)
Time (mean ± σ): 2.171 s ± 0.028 s [User: 1.189 s, System: 0.977 s]
Range (min … max): 2.117 s … 2.206 s 10 runs
Benchmark 2: update-ref: create 100k refs (revision = fd888311fbc)
Time (mean ± σ): 3.418 s ± 0.030 s [User: 2.371 s, System: 1.037 s]
Range (min … max): 3.377 s … 3.473 s 10 runs
Summary
update-ref: create 100k refs (revision = fd888311fbc~) ran
1.57 ± 0.02 times faster than update-ref: create 100k refs (revision = fd888311fbc)
The root caute of the performance regression is that we changed when
exactly blocks of an uninteresting type are being discarded. Previous to
the refactoring in the mentioned commit we'd load the block data, read
its type, notice that it's not the wanted type and discard the block.
After the commit though we don't discard the block immediately, but we
fully decode it only to realize that it's not the desired type. We then
discard the block again, but have already performed a bunch of pointless
work.
Fix the regression by making `reftable_block_init()` return early in
case the block is not of the desired type. This fixes the performance
hit:
Benchmark 1: update-ref: create 100k refs (revision = HEAD~)
Time (mean ± σ): 2.712 s ± 0.018 s [User: 1.990 s, System: 0.716 s]
Range (min … max): 2.682 s … 2.741 s 10 runs
Benchmark 2: update-ref: create 100k refs (revision = HEAD)
Time (mean ± σ): 1.670 s ± 0.012 s [User: 0.991 s, System: 0.676 s]
Range (min … max): 1.652 s … 1.693 s 10 runs
Summary
update-ref: create 100k refs (revision = HEAD) ran
1.62 ± 0.02 times faster than update-ref: create 100k refs (revision = HEAD~)
Note that the baseline performance is lower than in the original due to
a couple of unrelated performance improvements that have landed since
the original commit.

Makefile: avoid constant rebuilds with compilation database
Many contributors to software use a Language Server Protocol
implementation to allow their editor to learn structural information
about the code they write and provide additional features, such as
jumping to the declaration or definition of a function or type. In C,
the usual implementation is clangd, which requires compiling with clang.
Because C and C++ projects lack a standard file system layout and build
system, unlike languages such as Rust and Go, clangd requires a
compilation database to be generated by the clang compiler in order to
pass the proper compilation flags and discover all of the files
necessary to make the LSP work. This is done by setting
GENERATE_COMPILATION_DATABASE to "yes".
However, when that's enabled and the user runs "make" a second time,
all of the files are re-compiled, which is inconvenient for contributors
to Git, since it makes small changes or rebases recompile the entirety
of the codebase. This happens because the directory holding the
compilation database is updated anytime an object is built, so its
modification date will always be newer than the first object built.
To solve this, use the same trick we do just above for the .depend
directory and filter the compilation database directory out if it
already exists, which avoids making it a target to be built.

sequencer: rework reflog message handling
It has been reported that "git rebase --rebase-merges" can create
corrupted reflog entries like
e9c962f2ea0 HEAD@{8}: <binary>�: Merged in <branch> (pull request #4441)
This is due to a use-after-free bug that happens because
reflog_message() uses a static `struct strbuf` and is not called to
update the current reflog message stored in `ctx->reflog_message` when
creating the merge. This means `ctx->reflog_message` points to a stale
reflog message that has been freed by subsequent call to
reflog_message() by a command such as `reset` that used the return value
directly rather than storing the result in `ctx->reflog_message`.
Fix this by creating the reflog message nearer to where the commit is
created and storing it in a local variable which is passed as an
additional parameter to run_git_commit() rather than storing the message
in `struct replay_ctx`. This makes it harder to forget to call
`reflog_message()` before creating a commit and using a variable with a
narrower scope means that a stale value cannot carried across a from one
iteration of the loop to the next which should prevent any similar
use-after-free bugs in the future.
A existing test is modified to demonstrate that merges are now created
with the correct reflog message.

send-mail: improve checks for valid_fqdn
The current implementation of a valid Fully Qualified Domain Name
is not that strict. It just checks whether it has a dot (.) and
if using macOS, it should not end with .local. As per RFC1035[1],
from what I understood, the following checks need to be done:
- The domain must contain atleast one dot
- Each label (separated by dots) must be 1-63 characters long
- Labels must start and end with an alphanumeric character
- Labels can contain alphanumeric characters and hyphens
Here are some examples of valid and invalid labels:
'example.com', # Valid
'sub.example.com', # Valid
'my-domain.org', # Valid
'localhost', # Invalid (no dot)
'MacBook..', # Invalid (double dots)
'-example.com', # Invalid (starts with a hyphen)
'example-.com', # Invalid (ends with a hyphen)
'example..com', # Invalid (double dots)
'example', # Invalid (no TLD)
'example.local', # Invalid on macOS
'valid-domain.co.uk', # Valid
'123.example.com', # Valid
'example.com.', # Invalid (trailing dot)
'toolonglabeltoolonglabeltoolonglabeltoolonglabeltoolonglabeltoolonglabel.com', # Invalid (label > 63 chars)
Due to current implementation, I was not able to send emails from
Ubuntu. Upon debugging, I found that the SMTP domain being passed
to Outlook's servers was not valid.
Notice that an invalid domain name "MacBook.." is sent by git-send-email.
We have a fallback code that checks output from Net::Domain::domainname()
or asking domain method of an Net::SMTP instance to detect a misconfigured
hostname and replace it with fallback "localhost.localdomain", but the
valid_fqdn apparently is failing to say "MacBook.." is not a valid fqdn.
With this patch, the rule used in valid_fqdn is tightened, the beginning
part of the SMTP exchange looked like this:

t6011: fix misconversion from perl to sed
No, this is not about a quiz on regexp compatibility between Perl
and sed.
Back when cdbdc6bf (t: refactor tests depending on Perl substitution
operator, 2025-04-03) rewrote many uses of perl with sed, the general
pattern of the original scripts were
persumably because the author knew that replacing some_read_only_file
with "mv" at the last step would not work without "mv -f" in some
environments (GNU seems to succeed without giving any prompt when
not running interactively, which is what happens when running t/
scripts). Replacing perl with sed would be fine as long as sed with
updated regexp does the equivalent munging.
But one place used to use a different construct in the original:
perl -i.bak -p -e "regexp to munge" some_read_only_file
With _no_ temporary file or "mv", "perl -i" allows you to replace a
read-only file in place.
When we replaced the use of "perl" with "sed" in the said commit,
however, because "sed -i" is not portable, we rewrote that in-place
replacement to
sed "regexp to munge" some_read_only_file >some_tmp &&
mv some_tmp some_read_only_file
Again, unfortunately that does not work in some environment, without
"mv -f".
We could run "mv -f" here, but we would then need to remove "chmod
+w" and have them use "mv -f" instead at all places that were
touched cdbdc6bf (t: refactor tests depending on Perl substitution
operator, 2025-04-03) to be consistent (and more concise).
For now, let's make it consistent in the other direction by mimick
the other places that made the target read-write before moving.
Speaking of portability, the outcome of using "sed" on non-text
files is unspecified, so the entire exercise of cdbdc6bf may have
needed to be reverted if people still used ancient version of
"standard compliant" sed that barfs on non-text files, but these
days we may be able to get away with "BSDs and GNU seem OK with it"
;-) But one fix at a time.

Our CI needs to be aware of the location of the test output directory so
that it knows where to find test results. Some of our CI jobs achieve
this by setting the `TEST_OUTPUT_DIRECTORY` environment variable, which
ensures that the output will be written to that directory. Other jobs,
especially on GitHub Workflows, don't set that environment variable and
instead expect test results to be located in the source directory in
"t/".
The latter logic does not work with Meson though, as the test results
are not written into the source directory by default, but instead into
the build directory. As such, any job that uses Meson without setting
the environment variable will be unable to locate and aggregate results.
Fix this by explicitly setting the test output directory when we set up
the Meson build directory. Like this, we can easily default to "t/" in
the source directory when the value hasn't been set explicitly.

When the `win+Meson` job was added to Git's CI, modeled after the
`win+vs` job, it overlooked that the latter built the Git artifacts in
release mode.
The reason for this is that there is code in `compat/mingw.c` that turns
on the modal assertion dialogs in debug mode, which are very useful when
debugging interactively (as they offer to attach Visual Studio's
debugger), but they are scarcely useful in CI builds (where that modal
dialog would sit around, waiting for a human being to see and deal with
it, which obviously won't ever happen).
This problem was not realized immediately because of a separate bug: the
`win+Meson` job erroneously built using the `gcc` that is in the `PATH`
by default on hosted GitHub Actions runners. Since that bug was fixed by
switching to `--vsenv`, though, the t7001-mv test consistently timed out
after six hours in the CI builds on GitHub, quite often, and wasting
build minutes without any benefit in return.
The reason for this timeout was a symptom of aforementioned debug mode
problem, where the test case 'nonsense mv triggers assertion failure and
partially updated index' in t7001-mv triggered an assertion.
I originally proposed this here patch to address the timeouts in CI
builds. The Git project decided to address this timeout differently,
though: by fixing the bug that the t7001-mv test case demonstrated. This
does not address the debug mode problem, though, as an `assert()` call
could be triggered in other ways in CI, and it should still not cause
the CI build to hang but should cause Git to error out instead. To avoid
having to accept this here patch, it was then proposed to replace all
`assert()` calls in Git's code base by `BUG()` calls. This might be
reasonable for independent reasons, but it obviously still does not
address the debug mode problem, as `assert()` calls could be easily
re-introduced by mistake, and besides, Git has a couple of dependencies
that all may have their own `assert()` calls (which are then safely
outside the control of the Git project to remove), therefore this here
patch is still needed.
