When git-rebase invokes format-patch, it wants to make sure we use the
normal prefixes, and are not confused by diff.noprefix or similar. When
this was added in 5b220a6876 (Add --src/dst-prefix to git-formt-patch
in git-rebase.sh, 2010-09-09), we only had --src-prefix and --dst-prefix
to do so, which requires re-specifying the prefixes we expect to see.
These days we can say what we want more directly: just use the defaults.
This is a minor cleanup that should have no behavior change, but
hopefully the result expresses more clearly what the code is trying to
accomplish.

When accepting a packfile in git-receive-pack(1), we feed that packfile
into git-index-pack(1) to generate the packfile index. As the packfile
would often only contain unreachable objects until the references have
been updated, concurrently running garbage collection might be tempted
to delete the packfile right away and thus cause corruption. To fix
this, we ask git-index-pack(1) to create a `.keep` file before moving
the packfile into place, which is getting deleted again once all of the
reference updates have been processed.
Now in production systems we have observed that those `.keep` files are
sometimes not getting deleted as expected, where the result is that
repositories tend to grow packfiles that are never deleted over time.
This seems to be caused by a race when git-receive-pack(1) is killed
after we have migrated the kept packfile from the quarantine directory
into the main object database. While this race window is typically small
it can be extended for example by installing a `proc-receive` hook.
Fix this race by registering the lockfile as a tempfile so that it will
automatically be removed at exit or when receiving a signal.

The previous commit dropped support for diff.noprefix in format-patch.
While this will do the right thing in most cases (where sending patches
without a prefix was an accidental side effect of the sender preferring
to see their local patches without prefixes), it left no good option for
a project or workflow where you really do want to send patches without
prefixes. You'd be stuck using "--no-prefix" for every invocation.
So let's add a config option specific to format-patch that enables this
behavior. That gives people who have such a workflow a way to get what
they want, but makes it hard to accidentally trigger it.
A more backwards-compatible way of doing the transition would be to have
format.noprefix default to diff.noprefix when it's not set. But that
doesn't really help the "accidental" problem; people would have to
manually set format.noprefix=false. And it's unlikely that anybody
really wants format.noprefix=true in the first place. I'm adding it here
mostly as an escape hatch, not because anybody has expressed any
interest in it.

The output of format-patch respects diff.noprefix, but this usually ends
up being a hassle for people receiving the patch, as they have to
manually specify "-p0" in order to apply it.
I don't think there was any specific intention for it to behave this
way. The noprefix option is handled by git_diff_ui_config(), and
format-patch exists in a gray area between plumbing and porcelain.
People do look at the output, and we'd expect it to colorize things,
respect their choice of algorithm, and so on. But this particular option
creates problems for the receiver (in theory so does diff.mnemonicprefix,
but since we are always formatting commits, the mnemonic prefixes will
always be "a/" and "b/").
So let's disable it. The slight downsides are:
- people who have set diff.noprefix presumably like to see their
patches without prefixes. If they use format-patch to review their
series, they'll see prefixes. On the other hand, it is probably a
good idea for them to look at what will actually get sent out.
We could try to play games here with "is stdout a tty", as we do for
color. But that's not a completely reliable signal, and it's
probably not worth the trouble. If you want to see the patch with
the usual bells and whistles, then you are better off using "git
log" or "git show".
- if a project really does have a workflow that likes prefix-less
patches, and the receiver is prepared to use "-p0", then the sender
now has to manually say "--no-prefix" for each format-patch
invocation. That doesn't seem _too_ terrible given that the receiver
has to manually say "-p0" for each git-am invocation.

When handling OPT_FILENAME(), we have to stick the "prefix" (if any) in
front of the filename to make up for the fact that Git has chdir()'d to
the top of the repository. We can do this with prefix_filename(), but
there are a few special cases we handle ourselves.
Unfortunately the memory allocation is inconsistent here; if we do make
it to prefix_filename(), we'll allocate a string which the caller must
free to avoid a leak. But if we hit our special cases, we'll return the
string as-is, and a caller which tries to free it will crash. So there's
no way to win.
Let's consistently allocate, so that callers can do the right thing.
There are now three cases to care about in the function (and hence a
three-armed if/else):
1. we got a NULL input (and should leave it as NULL, though arguably
this is the sign of a bug; let's keep the status quo for now and we
can pick at that scab later)
2. we hit a special case that means we leave the name intact; we
should duplicate the string. This includes our special "-"
matching. Prior to this patch, it also included empty prefixes and
absolute filenames. But we can observe that prefix_filename()
already handles these, so we don't need to detect them.
3. everything else goes to prefix_filename()
I've dropped the "const" from the "char **file" parameter to indicate
that we're allocating, though in practice it's not really important.
This is all being shuffled through a void pointer via opt->value before
it hits code which ever looks at the string. And it's even a bit weird,
because we are really taking _in_ a const string and using the same
out-parameter for a non-const string. A better function signature would
be:
static char *fix_filename(const char *prefix, const char *file);
but that would mean the caller dereferences the double-pointer (and the
NULL check is currently handled inside this function). So I took the
path of least-change here.
Note that we have to fix several callers in this commit, too, or we'll
break the leak-checking tests. These are "new" leaks in the sense that
they are now triggered by the test suite, but these spots have always
been leaky when Git is run in a subdirectory of the repository. I fixed
all of the cases that trigger with GIT_TEST_PASSING_SANITIZE_LEAK. There
may be others in scripts that have other leaks, but we can fix them
later along with those other leaks (and again, you _couldn't_ fix them
before this patch, so this is the necessary first step).

A user can specify a filename to a command from the command line,
either as the value given to a command line option, or a command
line argument. When it is given as a relative filename, in the
user's mind, it is relative to the directory "git" was started from,
but by the time the filename is used, "git" would almost always have
chdir()'ed up to the root level of the working tree.
The given filename, if it is relative, needs to be prefixed with the
path to the current directory, and it typically is done by calling
prefix_filename() helper function. For commands that can also take
"-" to use the standard input or the standard output, however, this
needs to be done with care.
"git bundle create" uses the next word on the command line as the
output filename, and can take "-" to mean "write to the standard
output". It blindly called prefix_filename(), so running it in a
subdirectory did not quite work as expected.
Introduce a new helper, prefix_filename_except_for_dash(), and use
it to help "git bundle create" codepath.

For writing, "bundle create -" indicates that the bundle should be
written to stdout. But there's no matching handling of "-" for reading
operations. This is inconsistent, and a little inflexible (though one
can always use "/dev/stdin" on systems that support it).
However, it's easy to change. Once upon a time, the bundle-reading code
required a seekable descriptor, but that was fixed long ago in
e9ee84cf28 (bundle: allowing to read from an unseekable fd,
2011-10-13). So we just need to handle "-" explicitly when opening the
file.
We _could_ do this by handling "-" in read_bundle_header(), which the
reading functions all call already. But that is probably a bad idea.
It's also used by low-level code like the transport functions, and we
may want to be more careful there. We do not know that stdin is even
available to us, and certainly we would not want to get confused by a
configured URL that happens to point to "-".
So instead, let's add a helper to builtin/bundle.c. Since both the
bundle code and some of the callers refer to the bundle by name for
error messages, let's use the string "<stdin>" to make the output a bit
nicer to read.

In 79862b6b77 (bundle-create: progress output control, 2019-11-10),
"bundle create" learned about the --all-progress and
--all-progress-implied options, which were copied from pack-objects.
I think these were a mistake.
In pack-objects, "all-progress-implied" is about switching the behavior
between a regular on-disk "git repack" and the use of pack-objects for
push/fetch (where a fetch does not want progress from the server during
the write stage; the client will print progress as it receives the
data). But there's no such distinction for bundles. Prior to
79862b6b77, we always printed the write stage. Afterwards, a vanilla:
git bundle create foo.bundle
omits the write progress, appearing to hang (especially if your
repository is large or your disk is slow). That seems like a regression.
It's possible that the flexibility to disable the write-phase progress
_could_ be useful for bundle. E.g., if you did something like:
ssh some-host git bundle create foo.bundle |
git bundle unbundle
But if you are running both in real-time, why are you using bundles in
the first place? You're better off doing a real fetch.
But even if we did want to support that, it should be the exception, and
vanilla "bundle create" should display the full progress. So we'd want
to name the option "--no-write-progress" or something.
The "--all-progress" option itself is even worse. It exists in
pack-objects only for historical reasons. It's a mistake because it
implies "--progress", and we added "--all-progress-implied" to fix that.
There is no reason to propagate that mistake to new commands.
Likewise, the documentation for these options was pulled from
pack-objects. But it doesn't make any sense in this context. It talks
about "--stdout", but that is not even an option that git-bundle
supports.
This patch flips the default for "--all-progress-implied" back to
"true", fixing the regression in 79862b6b77. This turns that option
into a noop, and means that "--all-progress" is really the same as
"--progress". We _could_ drop them completely, but since they've been
shipped with Git since v2.25.0, it's polite to continue accepting them.
I didn't implement any sort of "--no-write-progress" here. I'm not at
all convinced it's necessary, and the discussion from the original
thread:
https://lore.kernel.org/git/20191110204126.30553-2-robbat2@gentoo.org/
shows that that the main focus was on getting --progress and --quiet
support, and not any kind of clever "real-time bundle over the network"
feature. But technically this patch is making it impossible to do
something that you _could_ do post-79862b6b77c.

We discourage the creation/update of single-level refs
because some upper-layer applications only work in specified

these single-level refnames may not be recognized. However,
we still hope users can delete them which have been created
by mistake.
Therefore, when updating branches on the server with
"git receive-pack", by checking whether it is a branch deletion
operation, it will determine whether to allow the update of
a single-level refs. This avoids creating/updating such
single-level refs, but allows them to be deleted.
On the client side, "git push" also does not properly fill in
the old-oid of single-level refs, which causes the server-side
"git receive-pack" to think that the ref's old-oid has changed
when deleting single-level refs, this causes the push to be
rejected. So the solution is to fix the client to be able to
delete single-level refs by properly filling old-oid.

In fb64ca526a (fsck: check index files in all worktrees, 2023-02-24), we
swapped out a call to vanilla repo_read_index() for a series of
read_index_from() calls, one per worktree. The code for the latter was
copied from add_index_objects_to_pending(), which checks for a positive
return value from the index reading function, and we do the same here in
fsck now.
But this is probably the wrong thing. I had interpreted the check as
"don't operate on the index struct if there was an error". But in
reality, if there is an error then the index-reading code will simply
die (which admittedly is not great for fsck, but that is not a new
problem).
The return value here is actually the number of entries read. So it
makes sense for add_index_objects_to_pending() to ignore a zero-entry
index (there is nothing to add). But for fsck, we would still want to
check any extensions, etc (though presumably it is unlikely to have them
in an empty index, I don't think it's impossible).
So we should ignore the return value from read_index_from() entirely.
This matches the behavior before fb64ca526a, when we ignored the return
value from repo_read_index().

If we encounter an error in an index file, we may say something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo
But if you have multiple worktrees, each with its own index, it can be
very helpful to know which file had the problem. So let's pass that path
down through the various index-fsck functions and use it where
appropriate. After this patch you should get something like:
error: 1234abcd: invalid sha1 pointer in resolve-undo of .git/worktrees/wt/index
That's a bit verbose, but since the point is that you shouldn't see this
normally, we're better to err on the side of more details.
I've also added the index filename to the name used by "fsck
--name-objects", which will show up if we find the object to be missing,
etc. This is bending the rules a little there, as the option claims to
write names that can be fed to rev-parse. But there is no revision
syntax to access the index of another worktree, so the best we can do is
make up something that a human will probably understand.
I did take care to retain the existing ":file" syntax for the current
worktree. So the uglier output should kick in only when it's actually
necessary. See the included tests for examples of both forms.

Some passwords have an expiry date known at generation. This may be
years away for a personal access token or hours for an OAuth access
token.
When multiple credential helpers are configured, `credential fill` tries
each helper in turn until it has a username and password, returning
early. If Git authentication succeeds, `credential approve`
stores the successful credential in all helpers. If authentication
fails, `credential reject` erases matching credentials in all helpers.
Helpers implement corresponding operations: get, store, erase.
The credential protocol has no expiry attribute, so helpers cannot
store expiry information. Even if a helper returned an improvised
expiry attribute, git credential discards unrecognised attributes
between operations and between helpers.
This is a particular issue when a storage helper and a
credential-generating helper are configured together:
[credential]
helper = storage # eg. cache or osxkeychain
helper = generate # eg. oauth
`credential approve` stores the generated credential in both helpers
without expiry information. Later `credential fill` may return an
expired credential from storage. There is no workaround, no matter how
clever the second helper. The user sees authentication fail (a retry
will succeed).
Introduce a password expiry attribute. In `credential fill`, ignore
expired passwords and continue to query subsequent helpers.
In the example above, `credential fill` ignores the expired password
and a fresh credential is generated. If authentication succeeds,
`credential approve` replaces the expired password in storage.
If authentication fails, the expired credential is erased by
`credential reject`. It is unnecessary but harmless for storage
helpers to self prune expired credentials.
Add support for the new attribute to credential-cache.
Eventually, I hope to see support in other popular storage helpers.
Example usage in a credential-generating helper

Instead of forcing the porcelain commands to always read the

This hopefully would make it more future-proof as we do not have to
think and decide whether we should call git_gpg_config() in the

A few git_config() callback functions that used to be custom
callbacks are now just a thin wrapper around git_default_config().
We could further remove, git_FOO_config and replace calls to
git_config(git_FOO_config) with git_config(git_default_config), but
to make it clear which ones are affected and the effect is only the

Commit 7550424804 ("name-rev: include taggerdate in considering the best
name", 2016-04-22) introduced the idea of using taggerdate in the
criteria for selecting the best name. At the time, a certain commit in
linux.git -- namely, aed06b9cfcab -- was being named by name-rev as
v4.6-rc1~9^2~792
which, while correct, was very suboptimal. Some investigation found
that tweaking the MERGE_TRAVERSAL_WEIGHT to lower it could give
alternate answers such as
v3.13-rc7~9^2~14^2~42
or
v3.13~5^2~4^2~2^2~1^2~42
A manual solution involving looking at tagger dates came up with
v3.13-rc1~65^2^2~42
which is much nicer. That workaround was then implemented in name-rev.
Unfortunately, the taggerdate heuristic is causing bugs. I was pointed
to a case in a private repository where name-rev reports a name of the
form
v2022.10.02~86
when users expected to see one of the form
v2022.10.01~2
(I've modified the names and numbers a bit from the real testcase.) As
you can probably guess, v2022.10.01 was created after v2022.10.02 (by a
few hours), even though it pointed to an older commit. While the
condition is unusual even in the repository in question, it is not the
only problematic set of tags in that repository. The taggerdate logic
is causing problems.
Further, it turns out that this taggerdate heuristic isn't even helping
anymore. Due to the fix to naming logic in 3656f84278 ("name-rev:
prefer shorter names over following merges", 2021-12-04), we get
improved names without the taggerdate heuristic. For the original
commit of interest in linux.git, a modern git without the taggerdate
heuristic still provides the same optimal answer of interest, namely:
v3.13-rc1~65^2^2~42
So, the taggerdate is no longer providing benefit, and it is causing
problems. Simply get rid of it.
However, note that "taggerdate" as a variable is used to store things
besides a taggerdate these days. Ever since commit ef1e74065c
("name-rev: favor describing with tags and use committer date to
tiebreak", 2017-03-29), this has been used to store committer dates and
there it is used as a fallback tiebreaker (as opposed to a primary
criteria overriding effective distance calculations). We do not want to
remove that fallback tiebreaker, so not all instances of "taggerdate"
are removed in this change.

Convert the invocation of the 'post-rewrite' hook run by 'git am' to

In our API this is supported by asking for a file path, rather
than by reading stdin. Reading directly from stdin would involve caching
the entire stdin (to memory or to disk) once the hook API is made to
support "jobs" larger than 1, along with support for executing N hooks

Make the replay_opts_release() function added in the preceding commit
non-static, and use it for freeing the "struct replay_opts"
constructed for "rebase" and "revert".
To safely call our new replay_opts_release() we'll need to stop
calling it in sequencer_remove_state(), and instead call it where we
allocate the "struct replay_opts" itself.
This is because in e.g. do_interactive_rebase() we construct a "struct
replay_opts" with "get_replay_opts()", and then call
"complete_action()". If we get far enough in that function without
encountering errors we'll call "pick_commits()" which (indirectly)
calls sequencer_remove_state() at the end.
But if we encounter errors anywhere along the way we'd punt out early,
and not free() the memory we allocated. Remembering whether we
previously called sequencer_remove_state() would be a hassle.
Using a FREE_AND_NULL() pattern would also work, as it would be safe
to call replay_opts_release() repeatedly. But let's fix this properly
instead, by having the owner of the data free() it.

Fix memory leaks resulting from a missing clear_pathspec().
- archive.c: Plug a leak in the "struct archiver_args", and
clear_pathspec() the "pathspec" member that the "parse_pathspec_arg()"
call in this function populates.
- builtin/clean.c: Fix a memory leak that's been with us since
893d839970 (clean: convert to use parse_pathspec, 2013-07-14).
- builtin/reset.c: Add clear_pathspec() calls to cmd_reset(),
including to the codepaths where we'd return early.
- builtin/stash.c: Call clear_pathspec() on the pathspec initialized
in push_stash().

Change an UNLEAK() added in 0c4542738e (clone: free or UNLEAK further
pointers when finished, 2021-03-14) to use a "to_free" pattern
instead. In this case the "repo" can be either this absolute_pathdup()
value, or in the "else if" branch seen in the context the the
"argv[0]" argument to "main()".
We can only free() the value in the former case, hence the "to_free"
pattern.

In 0bfb48e672 (builtin/commit-graph.c: UNLEAK variables, 2018-10-03)
this was made to UNLEAK(), but we can just as easily invoke the
free_commit_graph() function added in c3756d5b7f (commit-graph: add
free_commit_graph, 2018-07-11) instead.

Now that we've removed "git-add--interactive.perl" let's replace
mentions of it with "add-interactive.c". In the case of the "git add"
documentation we were using it as an example filename, so the mention
wasn't wrong, but using a dead file is slightly confusing.
The "borrowed" comment here likewise isn't wrong, but let's mention
the successor file instead. In the case of pathspec.c the implied TODO
item should refer to the current code (and the comment may not even be
current, I didn't check).

Now that the Perl "git-add--interactive" has gone away in the
preceding commit we don't need to pass along our desire for a mode as
a string, and can instead directly use the "enum add_p_mode", see
d2a233cb8b (built-in add -p: prepare for patch modes other than
"stage", 2019-12-21) for its introduction.
As a result of that the run_add_interactive() function would become a
trivial wrapper which would only run run_add_i() if a 0 (or now,
"NULL") "patch_mode" was provided. Let's instead remove it, and have
the one callsite that wanted the "NULL" case (interactive_add())
handle it.

Since [1] first released with Git v2.37.0 the built-in version of "add
-i" has been the default. That built-in implementation was added in
[2], first released with Git v2.25.0.
At this point enough time has passed to allow for finding any
remaining bugs in this new implementation, so let's remove the
fallback code.
As with similar migrations for "stash"[3] and "rebase"[4] we're
keeping a mention of "add.interactive.useBuiltin" in the
documentation, but adding a warning() to notify any outstanding users
that the built-in is now the default. As with [5] and [6] we should
follow-up in the future and eventually remove that warning.
1. 0527ccb1b5 (add -i: default to the built-in implementation,
2021-11-30)
2. f83dff60a7 (Start to implement a built-in version of `git add
--interactive`, 2019-11-13)
3. 8a2cd3f512 (stash: remove the stash.useBuiltin setting,
2020-03-03)
4. d03ebd411c (rebase: remove the rebase.useBuiltin setting,
2019-03-18)
5. deeaf5ee07 (stash: remove documentation for `stash.useBuiltin`,
2022-01-27)
6. 9bcde4d531 (rebase: remove transitory rebase.useBuiltin setting &
env, 2021-03-23)

Call strcspn(3) to find the length of a string terminated by NUL, NL or
slash instead of open-coding it. Adopt its return type, size_t, to
support strings of arbitrary length. Use that type in callers as well
for variables and function parameters that receive the return value.
