match_pathname(): give fnmatch one char of prefix context
In match_pathname(), which we use for matching .gitignore and
.gitattribute patterns, we are comparing paths with fnmatch patterns
(actually our extended wildmatch, which will be important). There's an
extra optimization there: we pre-compute the number of non-wildcard
characters at the beginning of the pattern and do an fspathncmp() on
that prefix.
That lets us avoid fnmatch entirely on patterns without wildcards, and
shrinks the amount of work we hand off to fnmatch. For a pattern like
"foo*.txt" and a path "foobar.txt", we'd cut away the matching "foo"
prefix and just pass "*.txt" and "bar.txt" to fnmatch().
But this misses a subtle corner case. In fnmatch(), we'll think
"bar.txt" is the start of the path, but it's not. This doesn't matter
for the pattern above, but consider the wildmatch pattern "foo**/bar"
and the path "foobar". These two should not match, because there is no
file named "bar", and the "**" applies only to the containing directory
name. But after removing the "foo" prefix, fnmatch will get "**/bar" and
"bar", which it does consider a match, because "**/" can match zero
directories.
We can solve this by giving fnmatch a bit more context. As long as it
has one byte of the matched prefix, then it will know that "bar" is not
the start of the path. In this example it would get "o**/bar" and
"obar", and realize that they cannot match.

We have two different repacking strategies in Git:
- The "gc" strategy uses git-gc(1).
- The "incremental" strategy uses multi-pack indices and `git
multi-pack-index repack` to merge together smaller packfiles as
determined by a specific batch size.
The former strategy is our old and trusted default, whereas the latter
has historically been used for our scheduled maintenance. But both
strategies have their shortcomings:
- The "gc" strategy performs regular all-into-one repacks. Furthermore
it is rather inflexible, as it is not easily possible for a user to
enable or disable specific subtasks.
- The "incremental" strategy is not a full replacement for the "gc"
strategy as it doesn't know to prune stale data.
So today, we don't have a strategy that is well-suited for large repos
while being a full replacement for the "gc" strategy.
Introduce a new "geometric" strategy that aims to fill this gap. This
strategy invokes all the usual cleanup tasks that git-gc(1) does like
pruning reflogs and rerere caches as well as stale worktrees. But where
it differs from both the "gc" and "incremental" strategy is that it uses
our geometric repacking infrastructure exposed by git-repack(1) to
repack packfiles. The advantage of geometric repacking is that we only
need to perform an all-into-one repack when the object count in a repo
has grown significantly.
One downside of this strategy is that pruning of unreferenced objects is
not going to happen regularly anymore. Every geometric repack knows to
soak up all loose objects regardless of their reachability, and merging
two or more packs doesn't consider reachability, either. Consequently,
the number of unreachable objects will grow over time.
This is remedied by doing an all-into-one repack instead of a geometric
repack whenever we determine that the geometric repack would end up
merging all packfiles anyway. This all-into-one repack then performs our
usual reachability checks and writes unreachable objects into a cruft
pack. As cruft packs won't ever be merged during geometric repacks we
can thus phase out these objects over time.
Of course, this still means that we retain unreachable objects for far
longer than with the "gc" strategy. But the maintenance strategy is
intended especially for large repositories, where the basic assumption
is that the set of unreachable objects will be significantly dwarfed by
the number of reachable objects.
If this assumption is ever proven to be too disadvantageous we could for
example introduce a time-based strategy: if the largest packfile has not
been touched for longer than $T, we perform an all-into-one repack. But
for now, such a mechanism is deferred into the future as it is not clear
yet whether it is needed in the first place.

- It is not possible to use git-gc(1) for scheduled maintenance.

builtin/maintenance: extend "maintenance.strategy" to manual maintenance
The "maintenance.strategy" configuration allows users to configure how
Git is supposed to perform repository maintenance. The idea is that we
provide a set of high-level strategies that may be useful in different
contexts, like for example when handling a large monorepo. Furthermore,
the strategy can be tweaked by the user by overriding specific tasks.
In its current form though, the strategy only applies to scheduled
maintenance. This creates something of a gap, as scheduled and manual
maintenance will now use _different_ strategies as the latter would
continue to use git-gc(1) by default. This makes the strategies way less
useful than they could be on the one hand. But even more importantly,
the two different strategies might clash with one another, where one of
the strategies performs maintenance in such a way that it discards
benefits from the other strategy.
So ideally, it should be possible to pick one strategy that then applies
globally to all the different ways that we perform maintenance. This
doesn't necessarily mean that the strategy always does the _same_ thing
for every maintenance type. But it means that the strategy can configure
the different types to work in tandem with each other.
Change the meaning of "maintenance.strategy" accordingly so that the
strategy is applied to both types, manual and scheduled. As preceding
commits have introduced logic to run maintenance tasks depending on this
type we can tweak strategies so that they perform those tasks depending
on the context.
Note that this raises the question of backwards compatibility: when the
user has configured the "incremental" strategy we would have ignored
that strategy beforehand. Instead, repository maintenance would have
continued to use git-gc(1) by default.
But luckily, we can match that behaviour by:
- Keeping all current tasks of the incremental strategy as
`MAINTENANCE_TYPE_SCHEDULED`. This ensures that those tasks will not
run during manual maintenance.
- Configuring the "gc" task so that it is invoked during manual
maintenance.
Like this, the user shouldn't observe any difference in behaviour.

builtin/maintenance: run maintenance tasks depending on type
We basically have three different ways to execute repository
maintenance:
1. Manual maintenance via `git maintenance run`.
2. Automatic maintenance via `git maintenance run --auto`.
3. Scheduled maintenance via `git maintenance run --schedule=`.
At the moment, maintenance strategies only have an effect for the last
type of maintenance. This is about to change in subsequent commits, but
to do so we need to be able to skip some tasks depending on how exactly
maintenance was invoked.
Introduce a new maintenance type that discern between manual (1 & 2) and
scheduled (3) maintenance. Convert the `enabled` field into a bitset so
that it becomes possible to specifiy which tasks exactly should run in a
specific context.
The types picked for existing strategies match the status quo:
- The default strategy is only ever executed as part of a manual
maintenance run. It is not possible to use it for scheduled
maintenance.
- The incremental strategy is only ever executed as part of a
scheduled maintenance run. It is not possible to use it for manual
maintenance.
The strategies will be tweaked in subsequent commits to make use of this
new infrastructure.

builtin/maintenance: make the geometric factor configurable
The geometric repacking task uses a factor of two for its geometric
sequence, meaning that each next pack must contain at least twice as
many objects as the next-smaller one. In some cases it may be helpful to
configure this factor though to reduce the number of packfile merges
even further, e.g. in very big repositories. But while git-repack(1)
itself supports doing this, the maintenance task does not give us a way
to tune it.
Introduce a new "maintenance.geometric-repack.splitFactor" configuration
to plug this gap.

Introduce a new "geometric-repack" task. This task uses our geometric
repack infrastructure as provided by git-repack(1) itself, which is a
strategy that especially hosting providers tend to use to amortize the
costs of repacking objects.
There is one issue though with geometric repacks, namely that they
unconditionally pack all loose objects, regardless of whether or not
they are reachable. This is done because it means that we can completely
skip the reachability step, which significantly speeds up the operation.
But it has the big downside that we are unable to expire objects over
time.
To address this issue we thus use a split strategy in this new task:
whenever a geometric repack would merge together all packs, we instead
do an all-into-one repack. By default, these all-into-one repacks have
cruft packs enabled, so unreachable objects would now be written into
their own pack. Consequently, they won't be soaked up during geometric
repacking anymore and can be expired with the next full repack, assuming
that their expiry date has surpassed.

This is done via `too_many_loose_objects()`, which takes as parameter
the `struct gc_config`. This configuration is only used to determine the
threshold. In a subsequent commit we'll add another caller of this
function that wants to pass a different limit than the one stored in
that structure.

The global `repack` variable is used to store all command line arguments
that we eventually want to pass to git-repack(1). It is being appended
to from multiple different functions, which makes it hard to follow the
logic. Besides being hard to follow, it also makes it unnecessarily hard
to reuse this infrastructure in new code.
Refactor the code so that we store this variable on the stack and pass
a pointer to it around as needed. This is done so that we can reuse
`add_repack_all_options()` in a subsequent commit.
The refactoring itself is straight-forward. One function that deserves
attention though is `need_to_gc()`: this function determines whether or
not we need to execute garbage collection for `git gc --auto`, but also
for `git maintenance run --auto`. But besides figuring out whether we
have to perform GC, the function also sets up the `repack` arguments.
For `git gc --auto` it's trivial to adapt, as we already have the
on-stack variable at our fingertips. But for the maintenance condition
it's less obvious what to do.
As it turns out, we can just use another temporary variable there that
we then immediately discard. If we need to perform GC we execute a child
git-gc(1) process to repack objects for us, and that process will have
to recompute the arguments anyway.

diff: simplify run_external_diff() quiet logic
We'd sometimes end up in run_external_diff() to do a dry-run diff (e.g.,
to find content-level changes for --quiet). We recognize this quiet mode
by seeing the lack of DIFF_FORMAT_PATCH in the output format.
But since introducing an explicit dry-run check via 3ed5d8bd73 (diff:
stop output garbled message in dry run mode, 2025-10-20), this logic can
never trigger. We can only get to this function by calling
diff_flush_patch(), and that comes from only two places:
1. A dry-run flush comes from diff_flush_patch_quietly(), which is
always in dry-run mode (so the other half of our "||" is true
anyway).
2. A regular flush comes from diff_flush_patch_all_file_pairs(),
which is only called when output_format has DIFF_FORMAT_PATCH in
it.
So we can simplify our "quiet" condition to just checking dry-run mode
(which used to be a specific flag, but recently became just a NULL
"file" pointer). And since it's so simple, we can just do that inline.

diff: drop dry-run redirection to /dev/null
As an added protection against dry-run diffs accidentally producing
output, we redirect diff_options.file to /dev/null. But as of the
previous patch, this now does nothing, since dry-run diffs are
implemented by setting "file" to NULL.
So we can drop this extra code with no change in behavior. This is
effectively a revert of 623f7af284 (diff: restore redirection to
/dev/null for diff_from_contents, 2025-10-17) and 3da4413dbc (diff: make

diff: replace diff_options.dry_run flag with NULL file
We introduced a dry_run flag to diff_options in b55e6d36eb (diff: ensure
consistent diff behavior with ignore options, 2025-08-08), with the idea
that the lower-level diff code could skip output when it is set.
As we saw with the bugs fixed by 3ed5d8bd73 (diff: stop output garbled
message in dry run mode, 2025-10-20), it is easy to miss spots. In the
end, we located all of them by checking where diff_options.file is used.
That suggests another possible approach: we can replace the dry_run
boolean with a NULL pointer for "file", as we know that using "file" in
dry_run mode would always be an error. This turns any missed spots from
producing extra output[1] into a segfault. Which is less forgiving, but
that is the point: this is indicative of a programming error, and
complaining loudly and immediately is good.
[1] We protect ourselves against garbled output as a separate step,
courtesy of 623f7af284 (diff: restore redirection to /dev/null for
diff_from_contents, 2025-10-17). So in that sense this patch can
only introduce user-visible errors (since any "bugs" were going to
/dev/null before), but the idea is to catch them rather than quietly
send garbage to /dev/null.

diff: drop save/restore of color_moved in dry-run mode
When running a dry-run content-level diff to check whether a "--quiet"
diff has any changes, we have always unset the color_moved variable
since the feature was added in 2e2d5ac184 (diff.c: color moved lines
differently, 2017-06-30). The reasoning is not given explicitly there,
but presumably the idea is that since color_moved requires a lot of
extra computation to match lines but does not actually affect the
found_changes flag, we want to skip it.
Later, in 3da4413dbc (diff: make sure the other caller of
diff_flush_patch_quietly() is silent, 2025-10-22) we copied the same
idea for other dry-run diffs.
But neither spot actually needs to reset this flag at all, because
diff_flush_patch() will not ever compute color_moved. Nor could it, as
it is only looking at a single file-pair, and we detect moves across
files. So color_moved is checked only when we are actually doing real
DIFF_FORMAT_PATCH output, and call diff_flush_patch_all_file_pairs().
So we can get rid of these extra lines to save and restore the
color_moved flag without changing the behavior at all. (Note that there
is no "restore" to drop for the second caller, as we know at that point
we are not generating any output and can just leave the feature
disabled).

diff: send external diff output to diff_options.file
Diff output usually goes to the process stdout, but it can be redirected
with the "--output" option. We store this in the "file" pointer of
diff_options, and all of the diff code should write there instead of to
stdout.
But there's one spot we missed: running an external diff cmd. We don't
redirect its output at all, so it just defaults to the stdout of the
parent process. We should instead point its stdout at our output file.
There are a few caveats to watch out for when doing so:
- The stdout field takes a descriptor, not a FILE pointer. We can pull
out the descriptor with fileno().
- The run-command API always closes the stdout descriptor we pass to
it. So we must duplicate it (otherwise we break the FILE pointer,
since it now points to a closed descriptor).
- We don't need to worry about closing our dup'd descriptor, since the
point is that run-command will do it for us (even in the case of an
error). But we do need to make sure we skip the dup() if we set
no_stdout (because then run-command will not look at it at all).
- When the output is going to stdout, it would not be wrong to dup()
the descriptor, but we don't need to. We can skip that extra work
with a simple pointer comparison.
- It seems like you'd need to fflush() the descriptor before handing
off a copy to the child process to prevent out-of-order writes. But
that was true even before this patch! It works because run-command
always calls fflush(NULL) before running the child.
The new test shows the breakage (and fix). The need for duplicating the
descriptor doesn't need a new test; that is covered by the later test
"GIT_EXTERNAL_DIFF with more than one changed files".

t7528: work around ETOOMANY in OpenSSH 10.1 and newer
In t7528 we spawn an SSH agent to verify that we can sign a commit via
it. This test has started to fail on some machines:
+++ ssh-agent
unix_listener_tmp: path "/home/pks/Development/git/build/test-output/trash directory.t7528-signed-commit-ssh/.ssh/agent/s.UTulegefEg.agent.UrPHumMXPq" too long for Unix domain socket
main: Couldn't prepare agent socket
As it turns out this is caused by a change in OpenSSH 10.1 [1]:
* ssh-agent(1), sshd(8): move agent listener sockets from /tmp to
under ~/.ssh/agent for both ssh-agent(1) and forwarded sockets
in sshd(8).
Instead of creating the socket in "/tmp", OpenSSH now creates the socket
in our home directory. And as the home directory gets modified to be
located in our test output directory we end up with paths that are
somewhat long. But Linux has a rather short limit of 108 characters for
socket paths, and other systems have even lower limits, so it is very
easy now to exceed the limit and run into the above error.
Work around the issue by using `ssh-agent -T`, which instructs it to
use the old behaviour and create the socket in "/tmp" again. This switch
has only been introduced with 10.1 though, so for older versions we have
to fall back to not using it. That's fine though, as older versions know
to put the socket into "/tmp" already.
An alternative approach would be to abbreviate the socket name itself so
that we create it as e.g. "sshsock" in the trash directory. But taking
the above example we'd still end up with a path that is 91 characters
long. So we wouldn't really have a lot of headroom, and it is quite
likely that some developers would see the issue on their machines.

However, the solution was not complete. When files are deleted,

To fix this, return early in emit_diff_symbol_from_struct() if

bisect: fix handling of `help` and invalid subcommands
As documented in git-bisect(1), `git bisect help` should display usage
information. However, since the migration of `git bisect` to a full
builtin command in 73fce29427 (Turn `git bisect` into a full built-in,
2022-11-10), this behavior was broken. Running `git bisect help` would,
instead of showing usage, either fail silently if already in a bisect
session, or otherwise trigger an interactive autostart prompt asking "Do
you want me to do it for you [Y/n]?".
Similarly, since df63421be9 (bisect--helper: handle states directly,
2022-11-10), running invalid subcommands like `git bisect foobar` also
led to the same behavior.
This occurred because `help` and other unrecognized subcommands were
being unconditionally passed to `bisect_state`, which then called
`bisect_autostart`, triggering the interactive prompt.
Fix this by:
1. Adding explicit handling for the `help` subcommand to show usage;
2. Validating that unrecognized commands are actually valid state
commands before calling `bisect_state`;
3. Showing an error with usage for truly invalid commands.
This ensures that `git bisect help` displays the usage as documented,
and invalid commands fail cleanly without entering interactive mode.
Alternate terms are still handled correctly through
`check_and_set_terms`.

commit-graph: add new config for changed-paths & recommend it in scalar
The changed-path Bloom filters feature has proven stable and reliable
over several years of use, delivering significant performance
improvement for file history computation in large monorepos. Currently
a user can opt-in to writing the changed-path Bloom filters using the
"--changed-paths" option to "git commit-graph write". The filters will
be persisted until the user drops the filters using the
"--no-changed-paths" option. For this functionality, refer to 0087a87ba8
(commit-graph: persist existence of changed-paths, 2020-07-01).
Large monorepos using Git's background maintenance to build and update
commit-graph files could use an easy switch to enable this feature
without a foreground computation. In this commit, we're proposing a new
config option "commitGraph.changedPaths":
* If "true", "git commit-graph write" will write Bloom filters,
equivalent to passing "--changed-paths";
* If "false" or "unset", Bloom filters will be written during "git
commit-graph write" only if the filters already exist in the current
commit-graph file. This matches the default behaviour of "git
commit-graph write" without any "--[no-]changed-paths" option. Note
"false" can disable a previous "true" config value but doesn't imply
"--no-changed-paths".
This config will always respect the precedence of command line option
"--[no-]changed-paths".
We also set this new config as optional recommended config in scalar to
turn on this feature for large repos.

t7500: fix tests with absolute path following ":(optional)" on Windows
On Windows, the MSYS layer translates absolute path names generated by
a shell script from the POSIX style /c/dir/file to the Windows style
C:/dir/file form that is understood by git.exe. This happens only when
the absolute path stands on its own as a program argument or a value of

test cases where ":(optional)" is inserted before an absolute path.
$PWD is used to construct the absolute paths, which gives the POSIX
form, and the result is ":(optional)/c/dir/template". Such command line
arguments are no longer recognized as absolute paths and do not undergo
translation.
Existing test cases that expect that the specified file does not exist
are not incorrect (after all, git.exe will not find /c/dir/template).
Yet, they are conceptually incorrect. That the use of $PWD is erroneous
is revealed by a test case that expects that the optional file exists.

When running "git status -z --short", the marker on modified index
entries (e.g., "M") is colorized, but the "??" marker for untracked

At first glance you might think that neither should be colorized, as
usually one would use "-z" to get machine-readable output. But this is a
tricky and unusual case. We have two output formats, "--short" and
"--porcelain" which are substantially similar, but differ in that
"--short" is for humans who want something short and "--porcelain" is
for machines. And "-z" by itself, without any other output option, does
default to "--porcelain", so "git status -z" will not colorize anything.
But if you explicitly ask for "-z" and "--short" together, then that is
asking for the human-readable output, but separated by NULs. This is
unlikely to be useful directly, but could for example be used if the
output will be shown to a human outside of the terminal. At any rate,
the current behavior is clearly wrong (since we colorize some things but
not others), and I think colorizing everything is the least-surprising
