Implement the built-in fsmonitor daemon for Linux using the inotify
API, bringing it to feature parity with the existing Windows and macOS
implementations.
The implementation uses inotify rather than fanotify because fanotify
requires either CAP_SYS_ADMIN or CAP_PERFMON capabilities, making it
unsuitable for an unprivileged user-space daemon. While inotify has
the limitation of requiring a separate watch on every directory (unlike
macOS's FSEvents, which can monitor an entire directory tree with a
single watch), it operates without elevated privileges and provides
the per-file event granularity needed for fsmonitor.
The listener uses inotify_init1(O_NONBLOCK) with a poll loop that
checks for events with a 50-millisecond timeout, keeping the inotify
queue well-drained to minimize the risk of overflows. Bidirectional
hashmaps map between watch descriptors and directory paths for efficient
event resolution. Directory renames are tracked using inotify's cookie
mechanism to correlate IN_MOVED_FROM and IN_MOVED_TO event pairs; a
periodic check detects stale renames where the matching IN_MOVED_TO
never arrived, forcing a resync.
New directory creation triggers recursive watch registration to ensure
all subdirectories are monitored. The IN_MASK_CREATE flag is used
where available to prevent modifying existing watches, with a fallback
for older kernels. When IN_MASK_CREATE is available and
inotify_add_watch returns EEXIST, it means another thread or recursive
scan has already registered the watch, so it is safe to ignore.
Remote filesystem detection uses statfs() to identify network-mounted
filesystems (NFS, CIFS, SMB, FUSE, etc.) via their magic numbers.
Mount point information is read from /proc/mounts and matched against
the statfs f_fsid to get accurate, human-readable filesystem type names
for logging. When the .git directory is on a remote filesystem, the
IPC socket falls back to $HOME or a user-configured directory via the
fsmonitor.socketDir setting.

* jk/diff-highlight-identical-pairs:
contrib/diff-highlight: do not highlight identical pairs
When diff-highlight was written, there was no way to fetch multiple
config keys _and_ have them interpreted as colors. So we were stuck
with either invoking git-config once for each config key, or fetching
them all and converting human-readable color names into ANSI codes
ourselves.
I chose the former, but it means that diff-highlight kicks off 6
git-config processes (even if you haven't configured anything, it has to
check each one).
But since Git 2.18.0, we can do:
git config --type=color --get-regexp=^color\.diff-highlight\.
to get all of them in one shot.
Note that any callers which pass in colors directly to the module via
@OLD_HIGHLIGHT and @NEW_HIGHLIGHT (like diff-so-fancy plans to do) are
unaffected; those colors suppress any config lookup we'd do ourselves.
You can see the effect like:
# diff-highlight suppresses git-config's stderr, so dump
# trace through descriptor 3
git show d1f33c753d | GIT_TRACE=3 diff-highlight 3>&2 >/dev/null
which drops from 6 lines down to 1.

Users of the module may want to pass in their own color config for a few
obvious reasons:
- they are pulling the config from different variables than
diff-highlight itself uses
- they are loading the config in a more efficient way (say, by parsing
git-config --list) and don't want to incur the six (!) git-config
calls that DiffHighlight.pm runs to check all config
Let's allow users of the module to pass in the color config, and
lazy-load it when needed if they haven't.

The diff-highlight tests use raw color bytes when comparing expected and
actual output. Let's use test_decode_color, which is our usual technique
in other tests. It makes reading test output diffs a bit easier, since
you're not relying on your terminal to interpret the result (or worse,
interpreting characters yourself via "cat -A").
This will also make it easier to add tests with new colors/attributes,
without having to pre-define the byte sequences ourselves.

The diff-highlight code does not rely on any perl features beyond what
perl 5.8 provides. We bumped it to v5.26 along with the rest of the
project's perl scripts in 702d8c1f3b (Require Perl 5.26.0, 2024-10-23).
There's some value in just having a uniform baseline for the project,
but I think diff-highlight is special here:
- it's in a contrib/ directory that is not frequently touched, so
there is little risk of Git developers getting annoyed that modern
perl features are not available
- it provides a module used by other projects. In particular,
diff-so-fancy relies on DiffHighlight.pm but does not otherwise
require a perl version more modern than 5.8.
Let's drop back to the more conservative requirement.

We pair lines for highlighting based on their position in the hunk. So
we should never see two identical lines paired, like:
-one
-two
+one
+something else
which would pair -one/+one, because that implies that the diff could
easily be shrunk by turning line "one" into context.
But there is (at least) one exception: removing a newline at the end of
a file will produce a diff like:
-foo
+foo
\No newline at end of file
And we will pair those two lines. As a result, we end up marking the
whole line, including the newline, as the shared prefix. And there's an
empty suffix.
The most obvious bug here is that when we try to print the highlighted
lines, we remove the trailing newline from the suffix, but do not bother
with the prefix (under the assumption that there had to be a difference
_somewhere_ in the line, and thus the prefix would not eat all the way
up to the newline). And so you get an extra line like:
-foo
+foo
\No newline at end of file
This is obviously ugly, but also causes interactive.diffFilter to
(rightly) complain that the input and output do not match their lines
1-to-1.
This could easily be fixed by chomping the prefix, too, but I think the
problem is deeper. For one, I suspect some of the other logic gets
confused by forming an array with zero-indexed element "3" in a
3-element array. But more importantly, we try not to highlight whole
lines, as there's nothing interesting to show there. So let's catch this
early in is_pair_interesting() and bail to our usual passthrough
strategy.

Passing a struct strbuf by value to a function copies the struct
but shares the underlying character array between caller and callee.
If the callee causes a reallocation, the caller's copy becomes a
dangling pointer, leading to a double-free when strbuf_release() is
called. There is no coccinelle rule to catch this pattern.
Jeff King suggested adding one during review of the
write_worktree_linking_files() fix [1], and noted that a reporting
rule using coccinelle's Python scripting extensions could emit a
descriptive warning, but we do not currently require Python support
in coccinelle.
Add a transformation rule that rewrites a by-value strbuf parameter
to a pointer. The detection is identical to what a Python-based
reporting rule would catch; only the presentation differs. The
resulting diff will not produce compilable code on its own (callers
and the function body still need updating), but the spatch output
alerts the developer that the signature needs attention. This is
consistent with the other rules in strbuf.cocci, which also rewrite
to the preferred form.

On Debian-alikes, POSIX sh has a hardcoded recursion depth
of 1000. This limit operates like bash's `$FUNCNEST` [1], but
it does not actually respect `$FUNCNEST`. This is non-standard
behavior. On other distros, the sh recursion depth is limited
only by the available stack size.
With certain history graphs, subtree splits are recursive—with
one recursion per commit. Attempting to split complex repos that
have thousands of commits, like [2], may fail on these distros.
Reduce the amount of recursion required by eagerly discovering
the complete range of commits to process.
The recursion is a side-effect of the rejoin-finder in
`find_existing_splits`. Rejoin mode, as in
git subtree split --rejoin -b hax main ...
improves the speed of later splits by merging the split history
back into `main`. This gives the splitting algorithm a stopping
point. The rejoin maps one commit on `main` to one split commit
on `hax`. If we encounter this commit, we know that it maps to
`hax`.
But this is only a single point in the history. Many splits
require history from before the rejoin. See patch content for
examples.
If pre-rejoin history is required, `check_parents` recursively
discovers each individual parent, with one recursion per commit.
The recursion deepens the entire tree, even if an older rejoin
is available. This quickly overwhelms the Debian sh stack.
Instead of recursively processing each commit, process *all* the
commits back to the next obvious starting point: i.e., either the
next-oldest --rejoin or the beginning of history. This is where the
recursion is likely to stop anyway.
While this still requires recursion, it is *considerably* less
recursive.

`should_ignore_subtree_split_commit` detects subtrees which are
outside of the current path --prefix and ignores them. This can
speed up splits of repositories that have many subtrees.
Since its inception [1], every iteration of this logic [2], [3]
incorrectly excludes commits. This alters the split history. The
split history and its commit hashes are API contract, so this is
not permissible.
While a commit from a different subtree may look like it doesn't
contribute anything to a split, sometimes it does. Merge commits
are a particular hot spot. For these, the pruning logic in
`copy_or_skip` performs:
1. a check for "treesame" parents
2. two different common ancestry checks
These checks operate on the **split history**, not the input
history. The split history omits commits that do not affect the
--prefix. This can significantly alter the ancestry of a merge.
In order to determine if `copy_or_skip` will skip a merge, it
is likely necessary to compute all the split history... which
is what `should_ignore_subtree_split_commit` tries to avoid.
To make this logic API-preserving, we could gate it behind a
new CLI argument. The present implementation is actually a
speed penalty in many cases, however, so this is not done here.
Remove the `should_ignore_subtree_split_commit` logic. This
fixes the regression reported in [4].

defined in the top-level Makefile, these flags must be consistently
defined when building git-credential-osxkeychain. Continuing to manually
adjust the git-credential-osxkeychain Makefile is cumbersome and
fragile.

The zsh completion function __git_zsh_cmd_alias() uses 'git config
--get-regexp' to enumerate aliases and then strips the "alias." prefix
from each key. For subsection-style aliases (alias.name.command), this
leaves "name.command" as the completion candidate instead of just
"name".
The bash completion does not have this problem because it goes through
'git --list-cmds=alias', which calls list_aliases() in C and already
handles both alias syntaxes correctly. However, zsh needs both the
alias name and its value for descriptive completion, which
--list-cmds=alias does not provide.
Add a hidden --aliases-for-completion option to 'git help', following
the existing --config-for-completion pattern. It outputs NUL-separated
"name\nvalue" pairs using list_aliases(), which correctly resolves both
the traditional (alias.name) and subsection (alias.name.command)
formats. Update __git_zsh_cmd_alias() to use it.

In the next commit we will start to parse more commits via the
commit-graph. This change will lead to a segfault though because we try
to access the tree of a commit via `repo_get_commit_tree()`, but:
- The commit has been parsed via the commit-graph, and thus its
`maybe_tree` field is not yet populated.
- We cannot use the commit-graph to populate the commit's tree because
we're in the process of writing the commit-graph.
The consequence is that we'll get a `NULL` pointer for the tree in
`write_graph_chunk_data()`.
In theory we are already mindful of this situation, as we explicitly use
`repo_parse_commit_no_graph()` to parse the commit without the help of
the commit-graph. But that doesn't do the trick as the commit is already
marked as parsed, so the function will not re-populate it. And as the
commit-graph has been closed, neither will `get_commit_tree_oid()` be
able to load the tree for us.
It seems like this issue can only be hit under artificial circumstances:
the error was hit via `git_test_write_commit_graph_or_die()`, which is
run by git-commit(1) and git-merge(1) in case `GIT_TEST_COMMIT_GRAPH=1`:
$ GIT_TEST_COMMIT_GRAPH=1 meson test t7507-commit-verbose \
--test-args=-ix -i
...
++ git -c commit.verbose=true commit --amend
hint: Waiting for your editor to close the file...
./test-lib.sh: line 1012: 55895 Segmentation fault (core dumped) git -c commit.verbose=true commit --amend
To the best of my knowledge, this is the only case where we end up
writing a commit-graph in the same process that might have already
consulted the commit-graph to look up arbitrary objects. But regardless
of that, this feels like a bigger accident that is just waiting to
happen.
Make the code more robust by extending `repo_parse_commit_no_graph()` to
unparse a commit first in case we detect it's coming from a graph. This
ensures that we will re-read the object without it, and thus we will
populate `maybe_tree` properly.
This fix shouldn't have any performance consequences: the function is
only ever called in the "commit-graph.c" code, and we'll only re-parse
the commit at most once.
Add an exclusion to our Coccinelle rules so that it doesn't complain
about us accessing `maybe_tree` directly.

The diff-highlight (in contrib/) comes with its own test script,
which relies on the initial branch name being 'master'. This is not
just encoded in the test logic, but in the illustration in the file
that shows the topology of the history.
Force the initial branch name to 'master' to allow it pass.

Recently the MEMZERO_ARRAY() macro was introduced. In that commit also
coccinelle rules were added to capture cases that can be converted to
use that macro.
Later a few more cases were manually converted to use the macro, but
coccinelle didn't capture those. Extend the rules to capture those as
well.
In various cases the code could be further beautified by removing
parentheses which are no longer needed. Modify the coccinelle rules to
optimize those as well and fix them.
During conversion indentation also used spaces where tabs should be
used, fix that in one go.
