The synopsis claims "push" can only be omitted when you do not give any

The explanation correctly claims that non-option arguments are not

But it also adds "-p" to the list of exceptions, even though it is an

In 5ee86c273b (repack: exclude cruft pack(s) from the MIDX where
possible, 2025-06-23), geometric repacking learned to exclude cruft
packs from the MIDX when 'repack.midxMustContainCruft' is set to
'false'.
This works because packs generated with '--stdin-packs=follow' rescue
any once-unreachable objects that later become reachable, making the
resulting packs closed under reachability without needing the cruft pack
in the MIDX.
However, packs above the geometric split that were not part of the
previous MIDX may not have full object closure. When such packs are
marked as excluded-closed ('^'), pack-objects treats them as a
reachability boundary and does not traverse through them during the
follow pass, potentially leaving the resulting pack without full
closure.
Fix this by marking packs above the geometric split that were not in the
previous MIDX as excluded-open ('!') instead of excluded-closed ('^').
This causes pack-objects to walk through their commits during the follow
pass, rescuing any reachable objects not present in the closed-excluded
packs.
Note that MIDXs which were generated prior to this change and are
unlucky enough to not be closed under reachability may still exhibit
this bug, as we treat all MIDX'd packs as closed. That is true in an
overwhelming number of cases, since in order to have a non-closed MIDX
you would have to:
- Generate a pack via an earlier geometric repack that is not closed
under reachability.
- Store that pack in the MIDX.
- Avoid picking any commits to receive reachability bitmaps which
happen to reach objects from which the missing objects are reachable.
In the extremely rare chance that all of the above should happen, an
all-into-one repack will resolve the issue.
Unfortunately, there is no perfect way to determine whether a MIDX'd
pack is closed outside of ensuring that there is a '1' bit in at least
one bitmap for every bit position corresponding to objects in that pack.
While this is possible to do, this approach would treat MIDX'd packs as
open in cases where there is at least one object that is not reachable
from the subset of commits selected for bitmapping.

In cd846bacc7 (pack-objects: introduce '--stdin-packs=follow',
2025-06-23), pack-objects learned to traverse through commits in
included packs when using '--stdin-packs=follow', rescuing reachable
objects from unlisted packs into the output.
When we encounter a commit in an excluded pack during this rescuing
phase we will traverse through its parents. But because we set
`revs.no_kept_objects = 1`, commit simplification will prevent us from
showing it via `get_revision()`. (In practice, `--stdin-packs=follow`
walks commits down to the roots, but only opens up trees for ones that
do not appear in an excluded pack.)
But there are certain cases where we *do* need to see the parents of an
object in an excluded pack. Namely, if an object is rescue-able, but
only reachable from object(s) which appear in excluded packs, then
commit simplification will exclude those commits from the object
traversal, and we will never see a copy of that object, and thus not
rescue it.
This is what causes the failure in the previous commit during repacking.
When performing a geometric repack, packs above the geometric split that
weren't part of the previous MIDX (e.g., packs pushed directly into
`$GIT_DIR/objects/pack`) may not have full object closure. When those
packs are listed as excluded via the '^' marker, the reachability
traversal encounters the sequence described above, and may miss objects
which we expect to rescue with `--stdin-packs=follow`.
Introduce a new "excluded-open" pack prefix, '!'. Like '^'-prefixed
packs, objects from '!'-prefixed packs are excluded from the resulting
pack. But unlike '^', commits in '!'-prefixed packs *are* used as
starting points for the follow traversal, and the traversal does not
treat them as a closure boundary.
In order to distinguish excluded-closed from excluded-open packs during
the traversal, introduce a new `pack_keep_in_core_open` bit on
`struct packed_git`, along with a corresponding `KEPT_PACK_IN_CORE_OPEN`
flag for the kept-pack cache.
In `add_object_entry_from_pack()`, move the `want_object_in_pack()`
check to *after* `add_pending_oid()`. This is necessary so that commits
from excluded-open packs are added as traversal tips even though their
objects won't appear in the output. As a consequence, the caller
`for_each_object_in_pack()` will always provide a non-NULL 'p', hence we
are able to drop the "if (p)" conditional.
The `include_check` and `include_check_obj` callbacks on `rev_info` are
used to halt the walk at closed-excluded packs, since objects behind a
'^' boundary are guaranteed to have closure and need not be rescued.
The following commit will make use of this new functionality within the
repack layer to resolve the test failure demonstrated in the previous
commit.

The '--stdin-packs' mode of pack-objects maintains two separate
string_lists: one for included packs, and one for excluded packs. Each
list stores the pack basename as a string and the corresponding
`packed_git` pointer in its `->util` field.
This works, but makes it awkward to extend the set of pack "kinds" that
pack-objects can accept via stdin, since each new kind would need its
own string_list and duplicated handling. A future commit will want to do
just this, so prepare for that change by handling the various "kinds" of
packs specified over stdin in a more generic fashion.
Namely, replace the two `string_list`s with a single `strmap` keyed on
the pack basename, with values pointing to a new `struct
stdin_pack_info`. This struct tracks both the `packed_git` pointer and a
`kind` bitfield indicating whether the pack was specified as included or
excluded.
Extract the logic for sorting packs by mtime and adding their objects
into a separate `stdin_packs_add_pack_entries()` helper.
While we could have used a `string_list`, we must handle the case where
the same pack is specified more than once. With a `string_list` only, we
would have to pay a quadratic cost to either (a) insert elements into
their sorted positions, or (b) a repeated linear search, which is
accidentally quadratic. For that reason, use a strmap instead.
This patch does not include any functional changes.

The `read_stdin_packs()` function added originally via 339bce27f4

The related change in 97ec43247c (pack-objects: declare 'rev_info' for

did not address it.
Ensure that we call `release_revisions()` appropriately to prevent a

When git-config matches a url, we copy the variable section name and
store it in the "section" member of a urlmatch_config struct. That
member is const, since the url-matcher will not touch it (and other
callers really will have a const string).
But that means that we have only a const pointer to our allocated
string. We have to cast away the constness when we free it, and likewise
when we assign NUL to tie off the "." separating the subsection and key.
This latter happens implicitly via a strchr() call, but recent versions
of glibc have added annotations that let the compiler detect that and
complain.
Let's keep our own "section" pointer for the non-const string, and then
just point config.section at it. That avoids all of the casting, both
explicit and implicit.

The previous commit cleared up some const confusion in handling parent
marks in revision.c, but we have roughly the same code duplicated in
rev-parse. This one is much easier to fix, because the handling of the
shortened string is all done in one place, after detecting any marks
(but without shortening the string between marks).
As a side note, I suspect this means that it behaves differently than
the revision.c parser for weird stuff like "foo^!^@^-", but that is
outside the scope of this patch.
While we are here, let's also rename the variable "dotdot", which is
totally misleading (and which we already fixed in revision.c long ago
via f632dedd8d (handle_revision_arg: stop using "dotdot" as a generic
pointer, 2017-05-19)).
Doing that here makes the diff a little messier, but it also lets the

variable while we are changing its semantics.

The existing implementation of 'git backfill' only includes downloading
missing blobs reachable from HEAD. Advanced uses may desire more general
commit limiting options, such as '--all' for all references, specifying a
commit range via negative references, or specifying a recency of use such as
with '--since=<date>'.
All of these options are available if we use setup_revisions() to parse the
unknown arguments with the revision machinery. This opens up a large number
of possibilities, only a small set of which are tested here.
For documentation, we avoid duplicating the option documentation and instead
link to the documentation of 'git rev-list'.
Note that these arguments currently allow specifying a pathspec, which
modifies the commit history checks but does not limit the paths used in the
backfill logic. This will be updated in a future change.

The function can_use_local_refs() prints a warning if there are no local

the reftable backend HEAD is not stored in the filesystem so reading
that file is pointless. In a repository using the files backend it is
unclear how useful printing it is - it would be better to diagnose the

Add a `--revert <branch>` mode to git replay that undoes the changes
introduced by the specified commits. Like --onto and --advance, --revert
is a standalone mode: it takes a branch argument and updates that branch
with the newly created revert commits.
At GitLab, we need this in Gitaly for reverting commits directly on bare
repositories without requiring a working tree checkout.
The approach is the same as sequencer.c's do_pick_commit() -- cherry-pick
and revert are just the same three-way merge with swapped arguments:
- Cherry-pick: merge(ancestor=parent, ours=current, theirs=commit)
- Revert: merge(ancestor=commit, ours=current, theirs=parent)
We swap the base and pickme trees passed to merge_incore_nonrecursive()
to reverse the diff direction.
Reverts are processed newest-first (matching git revert behavior) to
reduce conflicts by peeling off changes from the top. Each revert
builds on the result of the previous one via the last_commit fallback
in the main replay loop, rather than relying on the parent-mapping
used for cherry-pick.
Revert commit messages follow the usual git revert conventions: prefixed
with "Revert" (or "Reapply" when reverting a revert), and including
"This reverts commit <hash>.". The author is set to the current user
rather than preserving the original author, matching git revert behavior.

Teach "git hook run" and "git hook list" to reject hook event names
that are not recognized by Git. This helps catch typos such as
"prereceive" when "pre-receive" was intended, since in 99% of the
cases users want known (already-existing) hook names.
The list of known hooks is derived from the generated hook-list.h
(built from Documentation/githooks.adoc). This is why the Makefile
is updated, so builtin/hook.c depends on hook-list.h. In meson the
header is already a dependency for all builtins, no change required.

Disabled hooks were filtered out of the cache entirely, making them

global linter
local disabled no-leaks

Users running "git hook list" can see which hooks are configured but
have no way to tell at which config scope (local, global, system...)
each hook was defined.
Store the scope from ctx->kvi->scope in the single-pass config callback,
then carry it through the cache to the hook structs, so we can expose it
to users via the "git hook list --show-scope" flag, which mirrors the
existing git config --show-scope convention.
Without the flag the output is unchanged.
The scope is printed as a tab-separated prefix (like "git config --show-scope"),
making it unambiguously machine-parseable even when the friendly name
contains spaces.
Example usage:
$ git hook list --show-scope pre-commit
global linter
local no-leaks
hook from hookdir
Traditional hooks from the hookdir are unaffected by --show-scope since
the config scope concept does not apply to them.

Replace the custom function with string_list_clear_func() which
is a more common pattern for clearing a string_list.
To be able to do this, rework hook_clear() into hook_free(), so
it can be passed to string_list_clear_func().
A slight complication is the need to keep a copy of the internal
cb data free() pointer, however I think it's worth it since the
API becomes cleaner, e.g. no more calls with NULL function args
like hook_list_clear(hooks, NULL).
In other words, the callers don't need to keep track of hook
internal state to determine when cleanup is necessary or not
(pass NULL) because each `struct hook` now owns its data_free

strings into shared macros so they can be reused in multiple
usage arrays.
This is a preparatory refactoring for subsequent changes to
subcommand-specific help output.
