The --expire option for "git worktree list" and "git worktree prune"
only affects worktrees whose working directory path no longer exists.
The help text did not make this clear, and the documentation
inconsistently used "unused" for prune but "missing" for list.
Update the help text and documentation to consistently describe these
as "missing worktrees", and use "prune" instead of "expire" when
describing the effect on missing worktrees since the terminology is
clearer.
While at it, expand the description of the "prune" subcommand itself
to better explain what it does and when to use it, as suggested by
Junio.

By default git-last-modified(1) doesn't recurse into subtrees. So when
the pathspec contained a path in a subtree, the command would only print
the commit information about the parent tree of the path, like:
$ git last-modified -- path/file
aaa0aab1bbb2bcc3ccc4ddd5dde6eee7eff8fff9 path
Change the default behavior to give commit information about the exact
path instead:
$ git last-modified -- path/file
aaa0aab1bbb2bcc3ccc4ddd5dde6eee7eff8fff9 path/file
To achieve this, the default max-depth is changed to 0 and recursive is
always enabled.
The handling of option '-r' is modified to disable a max-depth,
resulting in the behavior of this option to remain unchanged.
No existing tests were modified, because there didn't exist any tests
covering the example above. But more tests are added to cover this now.

Option --max-depth is supported by git-last-modified(1), because it was
added to the diff machinery in a1dfa5448d (diff: teach tree-diff a
max-depth parameter, 2025-08-07).
This option is useful for everyday use of the git-last-modified(1)
command, so document it's existence in the man page.
To have it also appear in the help output of `git last-modified -h`,
move the handling of '--max-depth' to parse_options() in
builtin/last-modified.c itself. This prepares for the change in default
behavior in the next commit.

The command git-last-modified(1) already recognizes the option '-z', and
similar to many other commands this will make the output NUL-terminated
instead of using newlines. Although, this option is missing from the
documentation, so add it.
In addition to that, to have '-z' also appear in the help output of `git
last-modified -h`, move the handling of '-z' to parse_options() in
builtin/last-modified.c itself.
Before, the parsing of option '-z' was done by diff_opt_parse(), which
is called by setup_revisions(). That would fill in `struct
diff_options::line_termination`, but that field was not used by the diff
machinery itself. Thus it makes more sense to have the handling of that
option completely in builtin/last-modified.c.

The rev-list options in our manuals are quite long; git-replay's manual
is no exception. Since replay doesn't use the formatting options at all
(it has its own output format), drop them.

reversing changes made to 1627809eef.
It seems to have caused a few regressions, two of the three known
ones we have proposed solutions for. Let's give ourselves a bit
more room to maneuver during the pre-release freeze period and
restart once the 2.53 ships.
The documentation claims that --get-urlmatch is replaced by
git config get --all --show-names --url=<URL> <name>
However, --url cannot be combined with --all, and this command
fails in practice.
Update the replacement to use only --url, which matches the
actual behavior of --get-urlmatch.

If the changes in a commit being replayed are already in the branch
that the commits are being replayed onto, then "git replay" creates an
empty commit. This is confusing because the commit message no longer
matches the contents of the commit. Drop the commit instead. Commits
that start off empty are not dropped. This matches the behavior of
"git rebase --reapply-cherry-pick --empty=drop" and "git cherry-pick
--empty-drop".
If a branch points to a commit that is dropped it will be updated
to point to the last commit that was not dropped. This can be seen
in the new test where "topic1" is updated to point to the rebased
"C" as "F" is dropped because it is already upstream. While this is
a breaking change, "git replay" is marked as experimental to allow
improvements like this that change the behavior.

Implement a new "reword" subcommand for git-history(1). This subcommand
is similar to the user performing an interactive rebase with a single
commit changed to use the "reword" instruction.
The "reword" subcommand is built on top of the replay subsystem
instead of the sequencer. This leads to some major differences compared
to git-rebase(1):
- We do not check out the commit that is to be reworded and instead
perform the operation in-memory. This has the obvious benefit of
being significantly faster compared to git-rebase(1), but even more
importantly it allows the user to rewrite history even if there are
local changes in the working tree or in the index.
- We do not execute any hooks, even though we leave some room for
changing this in the future.
- By default, all local branches that contain the commit will be
rewritten. This especially helps with workflows that use stacked
branches.

When rewriting history via git-rebase(1) there are a few very common use
cases:
- The ordering of two commits should be reversed.
- A commit should be split up into two commits.
- A commit should be dropped from the history completely.
- Multiple commits should be squashed into one.
- Editing an existing commit that is not the tip of the current
branch.
While these operations are all doable, it often feels needlessly kludgey
to do so by doing an interactive rebase, using the editor to say what
one wants, and then perform the actions. Also, some operations like
splitting up a commit into two are way more involved than that and
require a whole series of commands.
Rebases also do not update dependent branches. The use of stacked
branches has grown quite common with competing version control systems
like Jujutsu though, so it clearly is a need that users have. While
rebases _can_ serve this use case if one always works on the latest
stacked branch, it is somewhat awkward and very easy to get wrong.
Add a new "history" command to plug these gaps. This command will have
several different subcommands to imperatively rewrite history for common
use cases like the above.

for each submodule can be impractical, so add a migration command to
submodule--helper to automatically create configs for all submodules

default (those created via git init or clone).
Important: setting init.defaultSubmodulePathConfig = true does

repositories will still have the extension disabled and will
require migration (for example via git submodule--helper command
added in the next commit).

The idea of this extension is to abstract away the submodule gitdir
path implementation: everyone is expected to use the config and not
worry about how the path is computed internally, either in git or
other implementations.
With this extension enabled, the submodule.<name>.gitdir repo config
becomes the single source of truth for all submodule gitdir paths.
The submodule.<name>.gitdir config is added automatically for all new
submodules when this extension is enabled.
Git will throw an error if the extension is enabled and a config is
missing, advising users how to migrate. Migration is manual for now.
E.g. to add a missing config entry for an existing "foo" module:
git config submodule.foo.gitdir .git/modules/foo

Move the check that detects "HEAD" refs that do not point at a branch
into `refs_fsck()`. This follows the same motivation as the preceding
commit.
Signed-off-by: Patrick Steinhardt <ps@pks.im>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
While most of the logic that verifies the consistency of refs is
driven by `refs_fsck()`, we still have a small handful of checks in
`fsck_head_link()`. These checks don't use the git-fsck(1) reporting
infrastructure, and as such it's impossible to for example disable
some of those checks.
One such check detects refs that point to the all-zeroes object ID.
Extract this check into the generic `refs_fsck_ref()` function that is
used by both the "files" and "reftable" backends.
Note that this will cause us to not return an error code from
`fsck_head_link()` anymore in case this error was detected. This is fine
though: the only caller of this function does not check the error code
anyway. To demonstrate this, adapt the function to drop its return value
altogether. The function will be removed in a subsequent commit anyway.

The default `--unstable` is a legacy format that predates `--stable`.
That’s why 2871f4d4 (builtin: patch-id: add --verbatim as a command mode,

Users of --unstable mainly care about compatibility with old git
versions, which unstripping the whitespace would break. Thus there
isn't a usecase for the combination of --verbatim and --unstable,
and we don't expose this so as to not add maintainence burden.
