A new builtin "git format-rev" is introduced for pretty formatting
one revision expression per line or commit object names found in
running text.
* kh/name-rev-custom-format:
format-rev: introduce builtin for on-demand pretty formatting
name-rev: make dedicated --annotate-stdin --name-only test
name-rev: factor code for sharing with a new command
name-rev: run clang-format before factoring code
name-rev: wrap both blocks in braces
Introduce a new builtin for pretty formatting one revision expression
per line or commit object names found in running text.
Sometimes you want to format commits. Most of the time you’re
walking the graph, e.g. getting a range of commits like
`master..topic`. That’s a job for git-log(1).
But there are times when you want to format commits that you encounter
on demand:
• Full hashes in running text that you might want to pretty-print
• git-last-modified(1) outputs full hashes that you can do the same
with
• git-cherry(1) has `-v` for commit subject, but maybe you want
something else?
But now you can’t use git-log(1), git-show(1), or git-rev-list(1):
• You can’t feed commits piecemeal to these commands, one input
for one output; they block until standard in is closed
• You can’t feed a list of possibly duplicate commits, like the output
of git-last-modified(1); they effectively deduplicate the output
Beyond these two points there’s also the input massage problem: you
cannot feed mixed input (revisions mixed with arbitrary text).
One might hope that git-cat-file(1) can save us. But it doesn’t
support pretty formats.
But there is one command that already both handles revisions as
arguments, revisions on standard input, and even revisions mixed in
with arbitrary text. Namely git-name-rev(1): the command for outputting
symbolic names for commits.
We made some room in `builtin/name-rev.c` two commits ago. Let’s
now add this new git-format-rev(1) command. Taking inspiration from
git-name-rev(1), there are two modes:
• revs: like git-name-rev(1) in argv mode, but one revision per line
on standard in
• text: like git-name-rev(1) with `--annotate-stdin`
***
We need to add this command to the exception list in
`t/t1517-outside-repo.sh` because it uses “EXPERIMENTAL!”
in the usage line.

We are about to introduce a new command git-format-rev(1) to this
file. Let’s factor some code so that we can share it with the new
command.
We want to be able to format commits found in freeform text, and
git-name-rev(1) already has a function for that but for symbolic
names. Let’s use a tagged union for the command-specific payload.

* js/maintenance-fix-deadlock-on-win10:
maintenance(geometric): do release the `.idx` files before repacking
mingw: optionally use legacy (non-POSIX) delete semantics
"git checkout -m another-branch" was invented to deal with local
changes to paths that are different between the current and the new
branch, but it gave only one chance to resolve conflicts. The command
was taught to create a stash to save the local changes.
* hn/git-checkout-m-with-stash:
checkout -m: autostash when switching branches
checkout: rollback lock on early returns in merge_working_tree
sequencer: teach autostash apply to take optional conflict marker labels
sequencer: allow create_autostash to run silently
stash: add --label-ours, --label-theirs, --label-base for apply
The 'git backfill' command now rejects revision-limiting options that
are incompatible with its operation, uses standard documentation for
revision ranges, and includes blobs from boundary commits by default
to improve performance of subsequent operations.
* en/backfill-fixes-and-edges:
backfill: default to grabbing edge blobs too
backfill: document acceptance of revision-range in more standard manner
backfill: reject rev-list arguments that do not make sense
As is done for all the other maintenance tasks, let's release the ODB
also before starting the geometric repacking. That way, the `.idx` files
won't be `mmap()`ed when they are to be deleted (which does not work on
Windows because you cannot delete files on that platform as long as they
are kept open by a process).
This regression was introduced by 9bc151850c (builtin/maintenance:
introduce "geometric-repack" task, 2025-10-24), but was only noticed
once geometric repacking was made the default in 452b12c2e0 (builtin/
maintenance: use "geometric" strategy by default, 2026-02-24).
The fix recapitulates my work from df76ee7b77f0 (run-command: offer to
close the object store before running, 2021-09-09) & friends.
To guard against future regressions of this kind, add a check to
`run_and_verify_geometric_pack()` in `t7900` that detects orphaned
`.idx` files left behind after repacking. Contrary to interactive
calls, the `git maintenance` call in that test case would _not_ block on
Windows, asking whether to retry deleting that file, which is the reason
why this bug was not caught earlier.
Furthermore, since the default behavior of `DeleteFileW()` was changed
at some point between Windows 10 Build 17134.1304 and Build 18363.657
to use POSIX semantics (see https://stackoverflow.com/a/60512798),
the added orphaned-`.idx` check would be insufficient to catch this
regression on modern Windows without emulating legacy delete semantics
via `GIT_TEST_LEGACY_DELETE=1`.
This fixes https://github.com/git-for-windows/git/issues/6210.

When switching branches with "git checkout -m", the attempted merge
of local modifications may cause conflicts with the changes made on
the other branch, which the user may not want to (or may not be able
to) resolve right now. Because there is no easy way to recover from
this situation, we discouraged users from using "checkout -m" unless
they are certain their changes are trivial and within their ability
to resolve conflicts.
Teach the -m flow to create a temporary stash before switching and
reapply it after. On success, the stash is silently applied and
the list of locally modified paths is shown, same as a successful
"git checkout" without "-m".
If reapplying causes conflicts, the stash is kept and the user is
told they can resolve and run "git stash drop", or run "git reset
--hard" and later "git stash pop" to recover their changes.

merge_working_tree() acquires the index lock via
repo_hold_locked_index() but several early return paths exit
without calling rollback_lock_file(), leaving the lock held.
While this is currently harmless because the process exits soon
after, it becomes a problem if the function is ever called more
than once in the same process.

Commit 302aff0922 (backfill: accept revision arguments, 2026-03-26) added
support for accepting revision arguments to backfill. This allows users
to do things like
git backfill --remotes ^v2.3.0
and then run many commands without triggering on-demand downloads of
blobs. However, if they have topics based on v2.3.0, they will likely
still trigger on-demand downloads. Consider, for example, the command
git log -p v2.3.0..topic
This would still trigger on-demand blob loadings after the backfill
command above, because the commit(s) with A as a parent will need to
diff against the blobs in A. In fact, multiple commands need blobs from
the lower boundary of the revision range:
* git log -p A..B # After backfill A..B
* git replay --onto TARGET A..B # After backfill TARGET^! A..B
* git checkout A && git merge B # After backfill A...B
Add an extra --[no-]include-edges flag to allow grabbing blobs from
edge commits. Since the point of backfill is to prevent on-demand blob
loading and these are common commands, default to --include-edges.

302aff0922 (backfill: accept revision arguments, 2026-03-26) added
support for passing revision arguments to 'git backfill' but documented
them only with a prose sentence:
You may also specify the commit limiting options from
git-rev-list(1).
No other command that accepts revision arguments documents them this
way. Commands like log, shortlog, and replay define a formal
<revision-range> entry and include rev-list-options.adoc. Commands like
bundle, fast-export, and filter-branch, which pass arguments through to
the revision machinery without including the full options file, still
define a formal <git-rev-list-args> entry explaining what is accepted.
Add a formal <revision-range> entry in the synopsis and OPTIONS section,
following the convention used by other commands, and mention that
commit-limiting options from git-rev-list(1) are also accepted.

Some rev-list options accepted by setup_revisions() are silently
ignored or actively counterproductive when used with 'git backfill',
because the path-walk API has its own tree-walking logic that bypasses
the mechanisms these options rely on:
* -S/-G (pickaxe) and --diff-filter work by computing per-commit
diffs in get_revision_1() and filtering commits whose diffs don't
match. Since backfill's goal is to download all blobs reachable
from commits in the range, filtering out commits based on diff
content would silently skip blobs -- the opposite of what users
want.
* --follow disables path pruning (revs->prune) and only makes
sense for tracking a single file through renames in log output.
It has no useful interaction with backfill.
* -L (line-log) computes line-level diffs to track the evolution
of a function or line range. Like pickaxe, it filters commits
based on diff content, which would cause blobs to be silently
skipped.
* --diff-merges controls how merge commit diffs are displayed.
The path-walk API walks trees directly and never computes
per-commit diffs, so this option would be silently ignored.
* --filter (object filtering, e.g. --filter=blob:none) is used by
the list-objects traversal but is completely ignored by the
path-walk API, so it would silently do nothing.
Rather than letting users think these options are being honored,
reject them with a clear error message.

Add a hook.<event>.enabled config key that disables all hooks for
a given event, when set to false, acting as a high-level switch
above the existing per-hook hook.<friendly-name>.enabled.
Event-disabled hooks are shown in "git hook list" with an
"event-disabled" tab-separated prefix before the name:
$ git hook list test-hook
event-disabled hook-1
event-disabled hook-2
With --show-scope:
$ git hook list --show-scope test-hook
local event-disabled hook-1
When a hook is both per-hook disabled and event-disabled, only
"event-disabled" is shown: the event-level switch is the more
relevant piece of information, and the per-hook "disabled" status
will surface once the event is re-enabled.
Using an event name as a friendly-name (e.g. hook.<event>.enabled)
can cause ambiguity, so a fatal error is issued when using a known
event name and a warning is issued for unknown event name, since
a collision cannot be detected with certainty for unknown events.

The "fsmonitor--daemon stop" command polls in a loop waiting for the
daemon to exit after sending a "quit" command over IPC. If the daemon

When the fsmonitor daemon is spawned as a background process, it may
inherit file descriptors from its parent that it does not need. In
particular, when the test harness or a CI system captures output through
pipes, the daemon can inherit duplicated pipe endpoints. If the daemon
holds these open, the parent process never sees EOF and may appear to
hang.
Set close_fd_above_stderr on the child process at both daemon startup
paths: the explicit "fsmonitor--daemon start" command and the implicit
spawn triggered by fsmonitor-ipc when a client finds no running daemon.
Also suppress stdout and stderr on the implicit spawn path to prevent
the background daemon from writing to the client's terminal.
Additionally, call setsid() when the daemon starts with --detach to
create a new session and process group. This prevents the daemon
from being part of the spawning shell's process group, which could
cause the shell's "wait" to block until the daemon exits.

The cookie wait in with_lock__wait_for_cookie() uses an infinite

to switch to pthread_cond_timedwait(), but the routine was not
available in git thread-utils.
On certain container or overlay filesystems, inotify watches may
succeed but events are never delivered. In this case the daemon
would hang indefinitely waiting for the cookie event, which in
turn causes the client to hang.

The `shown` kh_str_t was freed with kh_release_str() at a point in

client receives a trivial response, the code jumps to the `cleanup`
label, skipping the kh_release_str() call entirely and leaking the
hash table.
Fix this by initializing `shown` to NULL and moving the cleanup to the
`cleanup` label using kh_destroy_str(), which is safe to call on NULL.

taken.
