In previous commits, we started passing either repository or
git_hash_algo pointers around to various spots within builtin/repack.c
to reduce our dependency on the_repository in the hope of undef'ing
USE_THE_REPOSITORY_VARIABLE.
This commit takes us as far as we can (easily) go in that direction by
removing the only use of a convenience function that only exists when
USE_THE_REPOSITORY_VARIABLE is defined.
Unfortunately, the only other such function is "is_bare_repository()",
which is less than straightforward to convert into, say,
"repo_is_bare()", the latter of the two accepting a repository pointer.
Punt on that for now, and declare this commit as the stopping point for
our efforts in the direction of undef'ing USE_THE_REPOSITORY_VARIABLE.

In a similar spirit as previous commits, avoid referring directly to
"the_hash_algo" in builtin/repack.c::finish_pack_objects_cmd() and
instead accept one as a parameter to the function.
Since this function has a number of callers throughout the builtin, the
diff is a little noisier than previous commits. However, each hunk is
limited to passing the hash_algo parameter from a repository pointer
that is already in scope.

In b0b910e052 (cat-file.c: add batch handling for submodules,
2025-06-02), we began handling submodule entries specially when batching
cat-file like so:
$ echo :sha1collisiondetection | git.compile cat-file --batch-check
855827c583bc30645ba427885caa40c5b81764d2 submodule
Commit b0b910e052 notes that submodules are handled differently than
non-existent objects, which print "<given-name> <type>", since there is
(a) no object to resolve the OID of in the first place, and as commit
b0b910e052 notes, (b) for submodules in particular, it is useful to know
what commit it points at without having to spawn another Git process.
That commit does so by calling report_object_status() and passing in
"oid_to_hex(&data->oid)" for the "obj_name" parameter. This is
unnecessary, however, since report_object_status() will do the same
automatically if given a NULL "obj_name" argument.
That behavior dates back to 6a951937ae (cat-file: add
--batch-all-objects option, 2015-06-22), so rely on that instead of
having the caller open-code that part of report_object_status().

git-format-patch(1) supports Git notes by showing them beneath the
patch/commit message, similar to git-log(1). The command also supports
showing those same notes ref names in the range diff output.
Note *the same* ref names; any Git notes options or configuration
variables need to be handed off to the range-diff machinery. This works
correctly in the case when the range diff is on the cover letter. But it
does not work correctly when the output is a single patch with an
embedded range diff.
Concretely, git-format-patch(1) needs to pass `--[no-]notes` options
on to the range-diff subprocess in `range-diff.c`. This is handled in
`builtin/log.c` by the local variable `log_arg` in the case of mul-
tiple commits, but not in the single commit case where there is no
cover letter and the range diff is embedded in the patch output; the
range diff is then made in `log-tree.c`, whither `log_arg` has not
been propagated. This means that the range-diff subprocess reverts
to its default behavior, which is to act like git-log(1) w.r.t. notes.
We need to fix this. But first lay the groundwork by converting
`log_arg` to a struct member; next we can simply use that member
in `log-tree.c` without having to thread it from `builtin/log.c`.
No functional changes.

Rename `other_arg` to `log_arg` in `range_diff_options` and
related places.
“Other argument” comes from bd361918 (range-diff: pass through --notes
to `git log`, 2019-11-20) which introduced Git notes handling to
git-range-diff(1) by passing that option on to git-log(1). And that kind
of name might be fine in a local context. However, it was initially
spread among multiple files, and is now[1] part of the
`range_diff_options` struct. It is, prima facie, difficult to guess what
“other” means, especially when just looking at the struct.
But with a little reading we find out that it is used for `--[no-]notes`
and `--diff-merges`, which are both passed on to git-log(1). We should
just rename it to reflect this role; `log_arg` suggests, along with the
`strvec` type, that it is used to pass extra arguments to git-log(1).

The previous commit converted callers of setup_revisions() with a strvec
to use the safer and easier _from_strvec() variant.
Let's now convert spots that don't directly have a strvec, but receive
an argc/argv pair that eventually comes from one. We'll instead pass the
strvec down to the point where we call setup_revisions().
That makes these functions slightly less flexible if they were to grow
other callers that don't use strvecs, but this rigidity is buying us
some safety. It is only safe to pass the free_removed_argv_elements
option to setup_revisions() if we know the elements of argv/argc are
allocated on the heap. That isn't communicated in the type system when
we are passed the bare elements. But if we get a strvec, we know that
the elements are allocated strings.
And at any rate, each of these modified functions has only a single
caller (that has a strvec), so the loss of flexibility is unlikely to
ever matter.

The previous commit introduced a wrapper to make using setup_revisions()
with a strvec easier and safer. It converted spots that were already
doing most of what the wrapper did.
Let's now convert spots where we were not setting up the
free_removed_argv_elements flag. As discussed in the previous commit,
this probably isn't fixing any bugs or leaks (since these sites wouldn't
trigger the re-shuffling of argv that causes them). This is mostly
future-proofing us against setup_revisions() becoming more aggressive
about its re-shuffling.

The setup_revisions() function was designed to take the argc/argv pair
from the operating system. But we sometimes construct our own argv using
a strvec and pass that in. There are a few gotchas that callers need to
deal with here:
1. You should always pass the free_removed_argv_elements option via
setup_revision_opt. Otherwise, entries may be leaked if
setup_revisions() re-shuffles options.
2. After setup_revisions() returns, the strvec state is odd. We get a
reduced argc from setup_revisions() telling us how many unknown
options were left in place. Entries after that in argv may be
retained, or may be NULL (depending on how the reshuffling
happened). But the strvec's "nr" field still represents the
original value, and some of the entries it thinks it is still
storing may be NULL. Callers must be careful with how they access
it.
Some callers deal with (1), but not all. In practice they are OK because
they do not pass any options that would cause setup_revisions() to
re-shuffle (namely unknown options which may be relayed from the user,
and the use of the "--" separator). But it's probably a good idea to
consistently pass this option anyway to future-proof ourselves against
the details of setup_revisions() changing.
No callers address (2), though I don't think there any visible bugs.
Most of them simply call strvec_clear() and never otherwise look at the
result. And in fact, if they naively set foo.nr to the argc returned by
setup_revisions(), that would cause leaks! Because setup_revisions()
does not free consumed options[1], we have to leave the "nr" field of
the strvec at its original value to find and free them during
strvec_clear().
So I don't think there are any bugs to fix here, but we can make things
safer and simpler for callers. Let's introduce a helper function that
sets the free_removed_argv_elements automatically and shrinks the strvec
to represent the retained options afterwards (taking care to free the
now-obsolete entries).
We'll start by converting all of the call-sites which use the
free_removed_argv_elements option. There should be no behavior change
for them, except that their "shrunken" entries are cleaned up
immediately, rather than waiting for a strvec_clear() call.
[1] Arguably setup_revisions() should be doing this step for us if we
told it to free removed options, but there are many existing callers
which will be broken if it did. Introducing this helper is a
possible first step towards that.

In "git stash show", we do a first pass of parsing our command line
options by splitting them into revision args and stash args. These are
stored in strvecs, and we pass the revision args to setup_revisions().
But setup_revisions() may modify the argv we pass it, causing us to leak
some of the entries. In particular, if it sees a "--" string, that will
be dropped from argv. This is the same as other cases addressed by
f92dbdbc6a (revisions API: don't leak memory on argv elements that need
free()-ing, 2022-08-02), and we should fix it the same way: by passing
the free_removed_argv_elements option to setup_revisions().
The added test here is run only with SANITIZE=leak, without checking its
output, because the behavior of stash with "--" is a little odd:
1. Running "git stash show" will show --stat output. But running "git
stash show --" will show --patch.
2. I'd expect a non-option after "--" to be treated as a pathspec, so:
git stash show -p 1 -- foo
would look treat "1" as a stash (a synonym for stash@{1}) and
restrict the resulting diff to "foo". But it doesn't. We split the
revision/stash args without any regard to "--". So in the example
above both "1" and "foo" are stashes. Which is an error, but also:
git stash show -- foo
treats "foo" as a stash, not a pathspec.
These are both oddities that we may want to address (or may not, if we
want to retain historical quirks). But they are well outside the scope
of this patch. So for now we'll just let the tests confirm we aren't
leaking without otherwise expecting any behavior. If we later address
either of those points and end up with another test that covers "stash
show --", we can drop this leak-only test.

may be written to the pager instead of directly to the terminal. This
behaviour is problematic for two reasons:
- Color codes are meant for direct terminal output; writing them into
a pager does not seem like a sensible thing to do without additional
text.
- It is inconsistent with `git config --get-color`, which never uses a
pager, despite the fact that we claim `git config get --type=color`
to be a drop-in replacement in git-config(1).
Fix this by disabling the pager when outputting color sequences.

Our documentation for git-config(1) has a section where it explains how
to parse and use colors as Git would configure them. In order to get the
ANSI color escape sequence to reset the colors to normal we recommend
the following command:
$ git config get --type=color --default="reset" ""
This command is not supposed to parse any configuration keys. Instead,
it is expected to parse the "reset" default value and turn it into a
proper ANSI color escape sequence.
It was reported though [1] that this command doesn't work:
$ git config get --type=color --default="reset" ""
error: key does not contain a section:
This error was introduced in 4e51389000 (builtin/config: introduce "get"
subcommand, 2024-05-06), where we introduced the "get" subcommand to
retrieve configuration values. The preimage of that commit used `git
config --get-color "" "reset"` instead, which still works.
This use case is really quite specific to parsing colors, as it wouldn't
make sense to give git-config(1) a default value and an empty config key
only to return that default value unmodified. But with `--type=color` we
don't return the value directly; we instead parse the value into an ANSI
escape sequence.
As such, we can easily special-case this one use case:
- If the provided config key is empty;
- the user is asking for a color code; and
- the user has provided a default value,
then we call `get_color()` directly. Do so to make the documented
command work as expected.

With stash.index=true, git-stash(1) command now tries to reinstate the

common trap [1], [2]: "git stash apply" is not the reverse of "git stash

The implementation of `git pack-refs` is monolithic within

Split the original `builtin/pack-refs.c` file into two parts:
- A new shared library file, `pack-refs.c`, which contains the
core option parsing and packing logic in a new `pack_refs_core()`
helper function.
- The original `builtin/pack-refs.c`, which is now a thin wrapper
responsible only for defining the `git pack-refs` command and
calling the shared helper.
A new `pack-refs.h` header is also introduced to define the public

The `git pack-refs` command behaves generically, triggering a pack for
the 'files' backend and a compaction for the 'reftable' backend.
However, the name of the command and its corresponding API is
conceptually tied to the 'files' backend implementation.
To create a cleaner, more generic interface, refactor `git pack-refs` to
use the new `refs_optimize()` API. "Optimize" is a better semantic term
for this generic action.
This change allows `git pack-refs` to act as a backend-agnostic frontend
for reference optimization, and paves the way for the new `git refs
optimize` command to do the same.

The recently introduced new subcommand git-last-modified(1) runs into an
error in some scenarios. It then would exit with the message:
BUG: paths remaining beyond boundary in last-modified
This seems to happens for example when criss-cross merges are involved.
In that scenario, the function diff_tree_combined() gets called.
The function diff_tree_combined() copies the `struct diff_options` from
the input `struct rev_info` to override some flags. One flag is
`recursive`, which is always set to 1. This has been the case since the
inception of this function in af3feefa1d (diff-tree -c: show a merge
commit a bit more sensibly., 2006-01-24).
This behavior is incompatible with git-last-modified(1), when called
non-recursive (which is the default).
The last-modified machinery uses a hashmap for all the paths it wants to
get the last-modified commit for. Through log_tree_commit() the callback
mark_path() is called. The diff machinery uses diff_tree_combined()
internally, and due to it's recursive behavior the callback receives
entries inside subtrees, but not the subtree entries themselves. So a
directory is never expelled from the hashmap, and the BUG() statement
gets hit.
Because there are many callers calling into diff_tree_combined(), both
directly and indirectly, we cannot simply change it's behavior.
Instead, add a flag `no_recursive_diff_tree_combined` which supresses
the behavior of diff_tree_combined() to override `recursive` and set
this flag in builtin/last-modified.c.

A '--signed-commits=<mode>' option is already available when using
`git fast-export` to decide what should be done at export time about
commit signatures. At import time though, there is no option, or
other way, in `git fast-import` to decide about commit signatures.
To remediate that, let's add a '--signed-commits=<mode>' option to
`git fast-import` too.
For now the supported <mode>s are the same as those supported by
`git fast-export`.
The code responsible for consuming a signature is refactored into
the import_one_signature() and discard_one_signature() functions,
which makes it easier to follow the logic and add new modes in the
future.
In the 'strip' and 'warn-strip' modes, we deliberately use
discard_one_signature() to discard the signature without parsing it.
This ensures that even malformed signatures, which would cause the
parser to fail, can be successfully stripped from a commit.

During the 'prepare' phase of a reference transaction in the files
backend, we create the lock files for references to be created. When
using batched updates on case-insensitive filesystems, the entire
batched updates would be aborted if there are conflicting names such as:
refs/heads/Foo
refs/heads/foo
This affects all commands which were migrated to use batched updates in
Git 2.51, including 'git-fetch(1)' and 'git-receive-pack(1)'. Before
that, reference updates would be applied serially with one transaction
used per update. When users fetched multiple references on
case-insensitive systems, subsequent references would simply overwrite
any earlier references. So when fetching:
refs/heads/foo: 5f34ec0bfeac225b1c854340257a65b106f70ea6
refs/heads/Foo: ec3053b0977e83d9b67fc32c4527a117953994f3
refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56
The user would simply end up with:
refs/heads/foo: ec3053b0977e83d9b67fc32c4527a117953994f3
refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56
This is buggy behavior since the user is never informed about the
overrides performed and missing references. Nevertheless, the user is
left with a working repository with a subset of the references. Since
Git 2.51, in such situations fetches would simply fail without updating
any references. Which is also buggy behavior and worse off since the
user is left without any references.
The error is triggered in `lock_raw_ref()` where the files backend
attempts to create a lock file. When a lock file already exists the
function returns a 'REF_TRANSACTION_ERROR_GENERIC'. When this happens,
the entire batched updates, not individual operation, is aborted as if
it were in a transaction.
Change this to return 'REF_TRANSACTION_ERROR_CASE_CONFLICT' instead to
aid the batched update mechanism to simply reject such errors. The
change only affects batched updates since batched updates will reject
individual updates with non-generic errors. So specifically this would
only affect:
1. git fetch
2. git receive-pack
3. git update-ref --batch-updates
This bubbles the error type up to `files_transaction_prepare()` which
tries to lock each reference update. So if the locking fails, we check
if the rejection type can be ignored, which is done by calling
`ref_transaction_maybe_set_rejected()`.
As the error type is now 'REF_TRANSACTION_ERROR_CASE_CONFLICT',
the specific reference update would simply be rejected, while other
updates in the transaction would continue to be applied. This allows
partial application of references in case-insensitive filesystems when
fetching colliding references.
While the earlier implementation allowed the last reference to be
applied overriding the initial references, this change would allow the
first reference to be applied while rejecting consequent collisions.
This should be an okay compromise since with the files backend, there is
no scenario possible where we would retain all colliding references.
Let's also be more proactive and notify users on case-insensitive
filesystems about such problems by providing a brief about the issue
while also recommending using the reftable backend, which doesn't have
the same issue.

But it stores the bool result of want_color() in the same git_colorbool

We traditionally used "int" to store and pass around the values defined

Using an int doesn't produce incorrect results, but using the actual
enum makes the intent of the code more clear.
It would be nice if the compiler could catch cases where we used the
enum and an int interchangeably, since it's very easy to accidentally
check the boolean true/false of a colorbool like:
if (branch_use_color)
This is wrong because GIT_COLOR_UNKNOWN and GIT_COLOR_AUTO evaluate to
true in C, even though we may ultimately decide not to use color. But C
is pretty happy to convert between ints and enums (even with various
-Wenum-* warnings). So this sadly doesn't protect us from such mistakes,
but it hopefully does make the code easier to read.

Long ago Git's decision to show color for a subsytem was stored in a
tri-state variable: it could be true (1), false (0), or unknown (-1).
But since daa0c3d971 (color: delay auto-color decision until point of
use, 2011-08-17) we want to carry around a new state, "auto", which
bases the decision on the tty-ness of stdout (rather than collapsing
that "auto" state to a true/false immediately).
That commit introduced a set of GIT_COLOR_* defines to represent each
state: UNKNOWN, ALWAYS, NEVER, and AUTO. But it only used the AUTO
value, and left alone code using bare 0/1/-1 values. And of course since
then we've grown many new spots that use those bare values.
Let's switch all of these to use the named constants. That should make
the code a bit easier to read, as it is more obvious that we're

With 23a3a303 (update-index: use the bulk-checkin infrastructure,
2022-04-04), object database transactions were added to
git-update-index(1) to facilitate writing objects in bulk. With
transactions, newly added objects are instead written to a temporary
object directory and migrated to the primary object database upon
transaction commit.
When the --verbose option is specified, the subsequent set of objects
written are explicitly flushed via flush_odb_transaction() prior to
reporting the update. Flushing the object database transaction migrates
pending objects to the primary object database without marking the
transaction as complete. This is done so objects are immediately visible
to git-update-index(1) callers using the --verbose option and that rely
on parsing verbose output to know when objects are written.
Due to how git-update-index(1) parses arguments, options that come after
a filename are not considered during the object update. Therefore, it
may not be known ahead of time whether the --verbose option is present
and thus object writes are considered transactional by default until a
--verbose option is parsed.
Flushing a transaction after individual object writes negates the
benefit of writing objects to a transaction in the first place.
Furthermore, the mechanism to flush a transaction without actually
committing is rather awkward. Drop the call to flush_odb_transaction()
in favor of ending the transaction altogether when the --verbose flag is
encountered. Subsequent object writes occur outside of a transaction and
are therefore immediately visible which matches the current behavior.

The 'git sparse-checkout clean' subcommand is somewhat similar to 'git

The big difference is that it focuses on the directories that should not
be in the worktree due to cone-mode sparse-checkout. It also does not
discriminate in the kinds of files and focuses on deleting entire
directories.

When users change their sparse-checkout definitions to add new
directories and remove old ones, there may be a few reasons why
directories no longer in scope remain (ignored or excluded files still
exist, Windows handles are still open, etc.). When these files still
exist, the sparse index feature notices that a tracked, but sparse,
directory still exists on disk and thus the index expands. This causes a
performance hit _and_ the advice printed isn't very helpful. Using 'git
clean' isn't enough (generally '-dfx' may be needed) but also this may
not be sufficient.
Add a new subcommand to 'git sparse-checkout' that removes these
tracked-but-sparse directories.
The implementation details provide a clear definition of what is happening,
but it is difficult to describe this without including the internal
implementation details. The core operation converts the index to a sparse
index (in memory if not already on disk) and then deletes any directories in
the worktree that correspond with a sparse directory entry in that sparse
index.
In the most common case, this means that a file will be removed if it is
contained within a directory that is both tracked and outside of the
sparse-checkout definition. However, there can be exceptions depending on
the current state of the index:
* If the worktree has a modification to a tracked, sparse file, then that
file's parent directories will be expanded instead of represented as
sparse directories. Siblings of those parent directories may be
considered sparse.
* If the user staged a sparse file with "git add --sparse", then that file
loses the SKIP_WORKTREE bit until the sparse-checkout is reapplied. Until
then, that file's parent directories are not represented as sparse
directory entries and thus will not be removed. Siblings of those parent
directories may be considered sparse. (There may be other reasons why
the SKIP_WORKTREE bit was removed for a file and this impact on the
sparse directories will apply to those as well.)
* If the user has a merge conflict outside of the sparse-checkout
definition, then those conflict entries prevent the parent directories
from being represented as sparse directory entries and thus are not
removed.
* The cases above present reasons why certain _file conditions_ will impact
which _directories_ are considered sparse. The list of tracked
directories that are outside of the sparse-checkout definition but not
represented as a sparse directory further reduces the list of files that
will be removed.
For these complicated reasons, the documentation details a potential list of
files that will be "considered for removal" instead of defining the list
concretely. The special cases can be handled by resolving conflicts,
committing staged changes, and running 'git sparse-checkout reapply' to
update the SKIP_WORKTREE bits as expected by the sparse-checkout definition.
It is important to make clear that this operation will remove ignored and
excluded files which would normally be ignored even by 'git clean -f' unless
the '-x' or '-X' option is provided. This is the most extreme method for
doing this, but it works when the sparse-checkout is in cone mode and is
expected to rescope based on directories, not files.
The current implementation always deletes these sparse directories
without warning. This is unacceptable for a released version, but those
features will be added in changes coming immediately after this one.
Note that this will not remove an untracked directory (or any of its
contents) if its parent is a tracked directory within the sparse-checkout
definition. This is required to prevent removing data created by tools that
perform caching operations for editors or build tools.
Thus, 'git sparse-checkout clean' is both more aggressive and more careful
than 'git clean -fx':
* It is more aggressive because it will remove _tracked_ files within the
sparse directories.
* It is less aggressive because it will leave _untracked_ files that are
not contained in sparse directories.
These special cases will be handled more explicitly in a future change that
expands tests for the 'git sparse-checkout clean' command. We handle some of
the modified, staged, and committed states including some impact on 'git
status' after cleaning.

However, if GIT_PAGER_IN_USE is set in the environment, that overrides
the tty check, and we'll produce a colorized diff that chokes git-apply:
$ echo y | GIT_PAGER_IN_USE=1 git stash -p
[...]
Saved working directory and index state WIP on main: 4f2e2bb foo
error: No valid patches in input (allow with "--allow-empty")
Cannot remove worktree changes
Setting this variable is a relatively silly thing to do, and not
something most users would run into. But we sometimes do it in our tests
to stimulate color. And it is a user-visible bug, so let's fix it rather
than work around it in the tests.
The root issue here is that diff-tree (and other diff plumbing) should
probably not ever produce color by default. It does so not by parsing
color.ui, but because of the baked-in "auto" default from 4c7f1819b3
(make color.ui default to 'auto', 2013-06-10). But changing that is
risky; we've had discussions back and forth on the topic over the years.
E.g.:
https://lore.kernel.org/git/86D0A377-8AFD-460D-A90E-6327C6934DFC@gmail.com/.
So let's accept that as the status quo for now and protect ourselves by
passing --no-color to the child processes. This is the same thing we did
for add-interactive itself in 1c6ffb546b (add--interactive.perl: specify
--no-color explicitly, 2020-09-07).

Depth computation can end early if all remaining commits are flagged.
The current code determines if that's the case by checking all queue
items each time it dequeues a flagged commit. This can cause
quadratic complexity.
We could simply count the flagged items in the queue and then update
that number as we add and remove items. That would provide a general
speedup, but leave one case where we have to scan the whole queue: When
we flag a previously seen, but unflagged commit. It could be on the
queue and then we'd have to decrease our count.
We could dedicate an object flag to track queue membership, but that
would leave less for candidate tags, affecting the results. So use a
hash table, specifically an oidset of commit hashes, to track that.
This avoids quadratic behaviour in all cases and provides a nice
performance boost over the previous commit, 08bb69d70f (describe: use

As part of the ongoing effort to consolidate reference handling,
introduce a new `exists` subcommand. This command provides the same
functionality and exit-code behavior as `git show-ref --exists`, serving
as its modern replacement.
The logic for `show-ref --exists` is minimal. Rather than creating a
shared helper function which would be overkill for ~20 lines of code,
its implementation is intentionally duplicated here. This contrasts with
`git refs list`, where sharing the larger implementation of
`for-each-ref` was necessary.
Documentation for the new subcommand is also added to the `git-refs(1)`

When comparing large commit ranges (e.g., 250,000+ commits), range-diff
attempts to allocate an n×n cost matrix that can exhaust available
memory. For example, with 256,784 commits (n = 513,568), the matrix
would require approximately 256GB of memory (513,568² × 4 bytes),
causing either immediate segmentation faults due to integer overflow or
system hangs.
Add a memory limit check in get_correspondences() before allocating the
cost matrix. This check uses the total size in bytes (n² × sizeof(int))
and compares it against a configurable maximum, preventing both
excessive memory usage and integer overflow issues.
The limit is configurable via a new --max-memory option that accepts
human-readable sizes (e.g., "1G", "500M"). The default is 4GB for 64 bit
systems and 2GB for 32 bit systems. This allows comparing ranges of
approximately 32,000 (16,000) commits - generous for real-world use cases
while preventing impractical operations.
When the limit is exceeded, range-diff now displays a clear error
message showing both the requested memory size and the maximum allowed,
formatted in human-readable units for better user experience.
Example usage:
git range-diff --max-memory=1G branch1...branch2
git range-diff --max-memory=500M base..topic1 base..topic2
This approach was chosen over alternatives:
- Pre-counting commits: Would require spawning additional git processes
and reading all commits twice
- Limiting by commit count: Less precise than actual memory usage
- Streaming approach: Would require significant refactoring of the
current algorithm
This issue was previously discussed in:

Our 'git last-modified' performs a revision walk, and computes a diff at
each point in the walk to figure out whether a given revision changed
any of the paths it considers interesting.
When changed-path Bloom filters are available, we can avoid computing
many such diffs. Before computing a diff, we first check if any of the
remaining paths of interest were possibly changed at a given commit by
consulting its Bloom filter. If any of them are, we are resigned to
compute the diff.
If none of those queries returned "maybe", we know that the given commit
doesn't contain any changed paths which are interesting to us. So, we
can avoid computing it in this case.

When running 'git ls-files' with a pathspec, the index entries get
filtered according to that pathspec before iterating over them in
show_files(). In 78087097b8 (ls-files: add --sparse option,
2021-12-22), this iteration was prefixed with a check for the '--sparse'
option which allows the command to output directory entries; this
created a pre-loop call to ensure_full_index().
However, when a user runs 'git ls-files' where the pathspec matches
directories that are recursively matched in the sparse-checkout, there
are not any sparse directories that match the pathspec so they would not
be written to the output. The expansion in this case is just a
performance drop for no behavior difference.
Replace this global check to expand the index with a check inside the
loop for a matched sparse directory. If we see one, then expand the
index and continue from the current location. This is safe since the
previous entries in the index did not have any sparse directories and
thus would remain stable in this expansion.
A test in t1092 confirms that this changes the behavior.

When "core.commentString" is set to "auto" then "git commit" will
automatically select the comment character ensuring that it is not the
first character on any of the lines in the commit message. This was
introduced by commit 84c9dc2c5a (commit: allow core.commentChar=auto
for character auto selection, 2014-05-17). The motivation seems to be
to avoid commenting out lines from the existing message when amending
a commit that was created with a message from a file.
Unfortunately this feature does not work with:
* commit message templates that contain comments.
* prepare-commit-msg hooks that introduce comments.
* "git commit --cleanup=strip --edit -F <file>" which means that it
is incompatible with
- the "fixup" and "squash" commands of "git rebase -i" as the
comments added by those commands are then treated as part of
the commit message.
- the conflict comments added to the commit message by "git
cherry-pick", "git rebase" etc. as these comments are then
treated as part of the commit message.
It is also ignored by "git notes" when amending a note.
The issues with comments coming from a template, hook or file are a
consequence of the design of this feature and are therefore hard to
fix.
As the costs of this feature outweigh the benefits, deprecate it and
remove it in Git 3.0. If someone comes up with some patches that fix
all the issues in a maintainable way then I'd be happy to see this
change reverted.
The next commits will add a warning and some advice for users on how
they can update their config settings.

There's a call in describe_commit() to lookup_commit_reference(), but we
don't check the return value. If it returns NULL, we'll segfault as we
immediately dereference the result.
In practice this can never happen, since all callers pass an oid which
came from a "struct commit" already. So we can make this more obvious
by just taking that commit struct in the first place.

When describing a blob, we traverse from HEAD, remembering each commit
we saw, and then checking each blob to report the containing commit.
But if we haven't seen any commits at all, we'll segfault (we store the
"current" commit as an oid initialized to the null oid, causing
lookup_commit_reference() to return NULL).
This shouldn't be able to happen normally. We always start our traversal
at HEAD, which must be a commit (a property which is enforced by the
refs code). But you can trigger the segfault like this:
blob=$(echo foo | git hash-object -w --stdin)
echo $blob >.git/HEAD
git describe $blob
We can instead catch this case and return an empty result, which hits
the usual "we didn't find $blob while traversing HEAD" error.
This is a minor lie in that we did "find" the blob. And this even hints
at a bigger problem in this code: what if the traversal pointed to the
blob as _not_ part of a commit at all, but we had previously filled in
the recorded "current commit"? One could imagine this happening due to a
tag pointing directly to the blob in question.
But that can't happen, because we only traverse from HEAD, never from
any other refs. And the intent of the blob-describing code is to find
blobs within commits.
So I think this matches the original intent as closely as we can (and
again, this segfault cannot be triggered without corrupting your
repository!).
The test here does not use the formula above, which works only for the
files backend (and not reftables). Instead we use another loophole to
create the bogus state using only Git commands. See the comment in the
test for details.

When describing a blob, we search for it by traversing from HEAD. We do
this by feeding the name HEAD to setup_revisions(). But if we are on an
unborn branch, this will fail with a confusing message:
$ git describe $blob
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
It is OK for this to be an error (we cannot find $blob in an empty
traversal, so we'd eventually complain about that). But the error
message could be more helpful.
Let's resolve HEAD ourselves and pass the resolved object id to
setup_revisions(). If resolving fails, then we can print a more useful
message.

If describe_blob() does not find the blob in question, it returns an
empty strbuf, and we print an empty line. This differs from
describe_commit(), which always either returns an answer or calls die()
itself. As the blob function was bolted onto the command afterwards, I
think its behavior is not intentional, and it is just a bug that it does
not report an error.

We pass a "struct object_id" to describe_blob() by value. This isn't
wrong, as an oid is composed only of copy-able values. But it's unusual;
typically we pass structs by const pointer, including object_ids. Let's

It similarly makes sense for us to hold that pointer in the callback
data (rather than yet another copy of the oid).

Add the --format flag to git-repo-info. By using this flag, the users
can choose the format for obtaining the data they requested.
Given that this command can be used for generating input for other
applications and for being read by end users, it requires at least two
formats: one for being read by humans and other for being read by
machines. Some other Git commands also have two output formats, notably
git-config which was the inspiration for the two formats that were
chosen here:
- keyvalue, where the retrieved data is printed one per line, using =
for delimiting the key and the value. This is the default format,
targeted for end users.
- nul, where the retrieved data is separated by NUL characters, using
the newline character for delimiting the key and the value. This
format is targeted for being read by machines.

Currently, `git rev-parse` covers a wide range of functionality not
directly related to parsing revisions, as its name suggests. Over time,
many features like parsing datestrings, options, paths, and others
were added to it because there wasn't a more appropriate command
to place them.
Create a new Git command called `repo`. `git repo` will be the main
command for obtaining the information about a repository (such as
metadata and metrics).
Also declare a subcommand for `repo` called `info`. `git repo info`
will bring the functionality of retrieving repository-related
information currently returned by `rev-parse`.

Many of the commit-graph related functions take in both a repository and
the object database source (directly or via `struct commit_graph`) for
which we are supposed to load such a commit-graph. In the best case this
information is simply redundant as the source already contains a
reference to its owning object database, which in turn has a reference
to its repository. In the worst case this information could even

this function doesn't work on the source level but on the database level
instead.

Multi-pack indices store some information that is redundant with their
owning source:
- The locality bit that tracks whether the source is the primary
object source or an alternate.
- The object directory path the multi-pack index is located in.
- The pointer to the owning parent directory.
All of this information is already contained in `struct odb_source`. So
now that we always have that struct available when loading a multi-pack
index we have it readily accessible.

To load a multi-pack index the caller is expected to pass both the
repository and the object directory where the multi-pack index is
located. While this works, this layout has a couple of downsides:
- We need to pass in information reduntant with the owning source,
namely its object directory and whether the source is local or not.
- We don't have access to the source when loading the multi-pack
index. If we had that access, we could store a pointer to the owning
source in the MIDX and thus deduplicate some information.
- Multi-pack indices are inherently specific to the object source and
its format. With the goal of pluggable object backends in mind we
will eventually want the backends to own the logic of reading and
writing multi-pack indices. Making the logic work on top of object
sources is a step into that direction.
Refactor loading of multi-pack indices accordingly.
This surfaces one small problem though: git-multi-pack-index(1) and our
MIDX test helper both know to read and write multi-pack-indices located
in a different object directory. This issue is addressed by adding the
user-provided object directory as an in-memory alternate.

The act of giving "--no-index" tells Git to pretend that the current
directory is not under control of any Git index or repository, so
even when you happen to be in a Git controlled working tree, where
in that working tree should not matter.
But the start-up sequence tries to discover the top of the working
tree and chdir(2)'s there, even before Git passes control to the
subcommand being run. When diff_no_index() starts running, it
starts at a wrong (from the end-user's point of view who thinks
"git diff --no-index" is merely a better version of GNU diff)
directory, and the original directory the user started the command
is at "prefix".
Because the paths given from argv[] have already been adjusted to
account for this path shuffling by prepending the prefix, and
showing the resulting path by stripping the prefix, the effect of
these nonsense operations (nonsense in the context of "--no-index",
that is) is usually not observable.
Except for special cases like "-", where it is not preprocessed by
prepending the prefix.
Instead of papering over by adding more special cases only to cater
to the no-index codepath in the generic code, drive the diff
machinery more faithfully to what is going on. If the user started
"git diff --no-index" in directory X/Y/Z in a working tree
controlled by Git, and the start up sequence of Git chdir(2)'ed up
to directory X and left Y/Z in the prefix, revert the effect of the
start up sequence by chdir'ing back to Y/Z and emptying the prefix.

might check hidden options when responding to queries about deprecated

don't support "--help-all" outside of a git directory. Running (for
example)
git rebase --help-all
outside a directory fails in "setup_git_directory", erroring with the
localized form of

remote: bail early from set_head() if missing remote name
When renaming a remote we also need to rename all references
accordingly. But while we only need to rename references that are
contained in the "refs/remotes/$OLDNAME/" namespace, we end up using
`refs_for_each_rawref()` that iterates through _all_ references. We know
to exit early in the callback in case we see an irrelevant reference,
but ultimately this is still a waste of compute as we knowingly iterate
through references that we won't ever care about.
Improve this by using `refs_for_each_rawref_in()`, which knows to only
iterate through (potentially broken) references in a given prefix.
The following benchmark renames a remote with a single reference in a
repository that has 100k unrelated references. This shows a sizeable
improvement with the "files" backend:
Benchmark 1: rename remote (refformat = files, revision = HEAD~)
Time (mean ± σ): 42.6 ms ± 0.9 ms [User: 29.1 ms, System: 8.4 ms]
Range (min … max): 40.1 ms … 43.3 ms 10 runs
Benchmark 2: rename remote (refformat = files, revision = HEAD)
Time (mean ± σ): 31.7 ms ± 4.0 ms [User: 19.6 ms, System: 6.9 ms]
Range (min … max): 27.1 ms … 36.0 ms 10 runs
Summary
rename remote (refformat = files, revision = HEAD) ran
1.35 ± 0.17 times faster than rename remote (refformat = files, revision = HEAD~)
The "reftable" backend shows roughly the same absolute improvement, but
given that it's already significantly faster than the "files" backend
this translates to a much larger relative improvement:
Benchmark 1: rename remote (refformat = reftable, revision = HEAD~)
Time (mean ± σ): 18.2 ms ± 0.5 ms [User: 12.7 ms, System: 3.0 ms]
Range (min … max): 17.3 ms … 21.4 ms 110 runs
Benchmark 2: rename remote (refformat = reftable, revision = HEAD)

It was recently reported [1] that renaming a remote that has dangling
symrefs is broken. This issue can be trivially reproduced:
$ git init repo
Initialized empty Git repository in /tmp/repo/.git/
$ cd repo/
$ git remote add origin /dev/null
$ git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
$ git remote rename origin renamed
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/master
$ git symbolic-ref refs/remotes/renamed/HEAD
fatal: ref refs/remotes/renamed/HEAD is not a symbolic ref
As one can see, the "HEAD" reference did not get renamed but stays in
the same place. There are two issues here:
- We use `refs_resolve_ref_unsafe()` to resolve references, but we
don't pass the `RESOLVE_REF_NO_RECURSE` flag. Consequently, if the
reference does not resolve, the function will fail and we thus
ignore this branch.
- We use `refs_for_each_ref()` to iterate through the old remote's
references, but that function ignores broken references.
Both of these issues are easy to fix. But having a closer look at the
logic that renames remote references surfaces that it leaves a lot to be
desired overall.
The problem is that we're using O(|refs| + |symrefs| * 2) many reference
transactions to perform the renames. We first delete all symrefs, then
individually rename every direct reference and finally we recreate the
symrefs. On the one hand this isn't even remotely an atomic operation,
so if we hit any error we'll already have deleted all references.
But more importantly it is also extremely inefficient. The number of
transactions for symrefs doesn't really bother us too much, as there
should generally only be a single symref anyway ("HEAD"). But the
renames are very expensive:
- For the "reftable" backend we perform auto-compaction after every
single rename, which does add up.
- For the "files" backend we potentially have to rewrite the
"packed-refs" file on every single rename in case they are packed.
The consequence here is quadratic runtime performance. Renaming a
100k references takes hours to complete.
Refactor the code to use a single transaction to perform all the
reference updates atomically, which speeds up the transaction quite
significantly:
Benchmark 1: rename remote (refformat = files, revision = HEAD~)
Time (mean ± σ): 238.770 s ± 13.857 s [User: 91.473 s, System: 143.793 s]
Range (min … max): 204.863 s … 247.699 s 10 runs
Benchmark 2: rename remote (refformat = files, revision = HEAD)
Time (mean ± σ): 2.103 s ± 0.036 s [User: 0.360 s, System: 1.313 s]
Range (min … max): 2.011 s … 2.141 s 10 runs
Summary
rename remote (refformat = files, revision = HEAD) ran
113.53 ± 6.87 times faster than rename remote (refformat = files, revision = HEAD~)
For the "reftable" backend we see a significant speedup, as well, but
given that we don't have quadratic runtime behaviour there it's way less
extreme:
Benchmark 1: rename remote (refformat = reftable, revision = HEAD~)
Time (mean ± σ): 8.604 s ± 0.539 s [User: 4.985 s, System: 2.368 s]
Range (min … max): 7.880 s … 9.556 s 10 runs
Benchmark 2: rename remote (refformat = reftable, revision = HEAD)
Time (mean ± σ): 1.177 s ± 0.103 s [User: 0.446 s, System: 0.270 s]
Range (min … max): 1.023 s … 1.410 s 10 runs
Summary
rename remote (refformat = reftable, revision = HEAD) ran
7.31 ± 0.79 times faster than rename remote (refformat = reftable, revision = HEAD~)
There is one issue though with using atomic transactions: when nesting a
remote into itself it can happen that renamed references conflict with
the old referencse. For example, when we have a reference
"refs/remotes/origin/foo" and we rename "origin" to "origin/foo", then
we'll end up with an F/D conflict when we try to create the renamed
reference "refs/remotes/origin/foo/foo".
This situation is overall quite unlikely to happen: people tend to not
use nested remotes, and if they do they must at the same time also have
a conflicting refname. But the end result would be that the old remote
references stay intact whereas all the other parts of the repository
have been adjusted for the new remote name.
Address this by queueing and preparing the reference update before we
touch any other part of the repository. Like this we can make sure that
the reference update will go through before rewriting the configuration.
Otherwise, if the transaction fails to prepare we can gracefully abort
the whole operation without any changes having been performed in the
repository yet. Furthermore, we can detect the conflict and print some
helpful advice for how the user can resolve this situation. So overall,
the tradeoff is that:
- Reference transactions are now all-or-nothing. This is a significant
improvement over the previous state where we may have ended up with
partially-renamed references.
- Rewriting references is now significantly faster.
- We only rewrite the configuration in case we know that all
references can be updated.
- But we may refuse to rename a remote in case references conflict.
Overall this seems like an acceptable tradeoff.
While at it, fix the handling of symbolic/broken references by using
`refs_for_each_rawref()`. Add tests that cover both this reported issue
and tests that exercise nesting of remotes.
One thing to note: with this change we cannot provide a proper progress
monitor anymore as we queue the references into the transactions as we
iterate through them. Consequently, as we don't know yet how many refs
there are in total, we cannot report how many percent of the operation
is done anymore. But that's a small price to pay considering that you
now shouldn't need the progress monitor in most situations at all
anymore.

With `refs_for_each_reflog_ent()` callers can iterate through all the
reflog entries for a given reference. The callback that is being invoked
for each such entry does not receive the name of the reference that we
are currently iterating through. This isn't really a limiting factor, as
callers can simply pass the name via the callback data.
But this layout sometimes does make for a bit of an awkward calling
pattern. One example: when iterating through all reflogs, and for each
reflog we iterate through all refnames, we have to do some extra book
keeping to track which reference name we are currently yielding reflog
entries for.
Change the signature of the callback function so that the reference name
of the reflog gets passed through to it. Adapt callers accordingly and
start using the new parameter in trivial cases. The next commit will
refactor the reference migration logic to make use of this parameter so
that we can simplify its logic a bit.

While we provide a couple of subcommands in git-reflog(1) to remove

this is not an operation that really would be needed for many use cases
out there, or otherwise people would have complained that such a command
does not exist yet. But the introduction of the "reftable" backend
changes the picture a bit, as it is now basically impossible to manually
append a reflog entry if one wanted to do so due to the binary format.
Plug this gap by introducing a simple "write" subcommand. For now, all
this command does is to append a single new reflog entry with the given
object IDs and message to the reflog. More specifically, it is not yet
possible to:
- Write multiple reflog entries at once.
- Insert reflog entries at arbitrary indices.
- Specify the date of the reflog entry.
- Insert reflog entries that refer to nonexistent objects.
If required, those features can be added at a future point in time. For
now though, the new command aims to fulfill the most basic use cases
while being as strict as possible when it comes to verifying parameters.

Git's reference management is distributed across multiple commands. As
part of an ongoing effort to consolidate and modernize reference
handling, introduce a `list` subcommand under the `git refs` umbrella as

Add documentation for the new command. The man page leverages the shared

options.
Move the option parsing, filtering, and formatting logic from

In "git remote set-head", we can take varying numbers of arguments
depending on whether we saw the "-d" or "-a" options. But the first
argument is always the remote name.
The current code is somewhat awkward in that it conditionally handles
the remote name up-front like this:
if (argc)
remote = ...from argv[0]...
and then only later decides to bail if we do not have the right number
of arguments for the options we saw.
This makes it hard to figure out if "remote" is always set when it needs
to be. Both for humans, but also for compilers; with -Og, gcc complains
that "remote" can be accessed without being initialized (although this
is not true, as we'd always die with a usage message in that case).
Let's instead enforce the presence of the remote argument up front,
which fixes the compiler warning and is easier to understand. It does
mean duplicating the code to print a usage message, but it's a single
line.

When building with clang-22 and DEVELOPER=1 mode, this warning causes us
to fail compilation:
builtin/revert.c:114:13: error: default initialization of an object of type 'const char' leaves the object uninitialized [-Werror,-Wdefault-const-init-var-unsafe]
114 | const char sentinel_value;
| ^
The compiler is right that this code is a bit funny. We declare a const
value without an initializer. It cannot be assigned to because of the
const, but without an initializer it has no predictable value. So as a
variable it can never have any useful function, and if we tried to look
at it, we'd get undefined behavior.
But it does have a function. We never use its value, but rather use its
address as a sentinel value for some other variables:
const char *gpg_sign = &sentinel_value;
...maybe set gpg_sign via parse_options...
if (gpg_sign != &sentinel_value)
...we got a non-default value...
Normally we'd use NULL as a sentinel value for a pointer, but it doesn't
work here because we also want to detect --no-gpg-sign, which is marked
by setting the pointer to NULL. We need a separate "this was not
touched" value, which is what this sentinel variable gives us.
So the code is correct as-is, but the sentinel variable itself is funny
enough that it's understandable for a compiler warning to flag it. Let's
try to appease the compiler.
There are a few possible options:
1. Instead of a variable, we could just construct an artificial
sentinel address like "1", "-1", etc. I think these technically
fall afoul of the C standard (even if we do not access them, even
constructing invalid pointers is not always allowed). But it's also
something we do elsewhere, and even happens in some standard
interfaces (e.g., mmap()'s MMAP_FAILED value). It does involve some
annoying casts, though.
2. We can mark it as static. That gives it a definite value, but
perhaps makes people wonder if the static-ness is important, when
it's not.
3. We can just give it a value to shut the compiler up, even though
nobody cares about that value.
I went with (3) here as the smallest and most obvious change.

Optimize the sequence get+put to peek+replace to avoid one unnecessary

Do that by tracking partial get operations in a prio_queue wrapper,
struct lazy_queue, and using wrapper functions that turn get into peek
and put into replace as needed. This is simpler than tracking the
state explicitly in the calling code.
We get a nice speedup on top of the previous patch's conversion to

The callee parse_choice() only needs to access a NUL-terminated

builtin/clean.c:parse_choice() is fed a single line of input, which
is space or comma separated list of tokens, and a list of menu
items. It parses the tokens into number ranges (e.g. 1-3 that means
the first three items) or string prefix (e.g. 's' to choose the menu
item "(s)elect") that specify the elements in the menu item list,
and tells the caller which ones are chosen.
For parsing the input string, it uses strbuf_split() to split it
into bunch of strbufs. Instead use string_list_split_in_place(),
for a few reasons.
* strbuf_split() is a bad API function to use, that yields an array
of strbuf that is a bad data structure to use in general.
* string_list_split_in_place() allows you to split with "comma or
space"; the current code has to preprocess the input string to
replace comma with space because strbuf_split() does not allow
this.

When you pass a structure by value, the callee can modify the
contents of the structure that was passed in without having to worry
about changing the structure the caller has. Passing structure by
value sometimes (but not very often) can be a valid way to give
callee a temporary variable it can freely modify.
But not a structure with members that are pointers, like a strbuf.
builtin/clean.c:list_and_choose() reads a line interactively from
the user, and passes the line (in a strbuf) to parse_choice() by
value, which then munges by replacing ',' with ' ' (to accept both
comma and space separated list of choices). But because the strbuf
passed by value still shares the underlying character array buf[],
this ends up munging the caller's strbuf contents.
This is a catastrophe waiting to happen. If the callee causes the
strbuf to be reallocated, the buf[] the caller has will become
dangling, and when the caller does strbuf_release(), it would result
in double-free.
Stop calling the function with misleading call-by-value with strbuf.

This patch compliments the previous commit, where builtins that use
add-patch infrastructure now respect diff.context and
diff.interHunkContext file configurations.
In particular, this patch helps users who don't want to set persistent
context configurations or just want a way to override them on a one-time
basis, by allowing the relevant builtins to accept corresponding command
line options that override the file configurations.
This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

Adding a submodule at a path that previously hosted
another submodule (e.g., 'child') reuses the submodule
name derived from the path. If the original submodule
was only moved (e.g., to 'child_old') and not renamed,
this silently overwrites its configuration in .gitmodules.
This behavior loses user configuration and causes
confusion when the original submodule is expected
to remain intact. It assumes that the path-derived
name is always safe to reuse, even though the name
might still be in use elsewhere in the repository.
Teach module_add() to check if the computed submodule
name already exists in the repository's submodule config,
and if so, refuse the operation unless the user explicitly
renames the submodule or uses the --force option,
which will automatically generate a unique name by
appending a number (e.g., child1).

In "config.c" we host both the business logic to read and write config
files as well as the logic to parse specific Git-related variables. On
the one hand this is mixing concerns, but even more importantly it means
that we cannot easily remove the dependency on `the_repository` in our
config parsing logic.
Move the logic into "environment.c". This file is a grab bag of all
kinds of global state already, so it is quite a good fit. Furthermore,
it also hosts most of the global variables that we're parsing the config
values into, making this an even better fit.
Note that there is one hidden change: in `parse_fsync_components()` we
use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But
as -Wsign-compare warnings are enabled in this file this causes a
compiler warning. The issue is fixed by using a `size_t` instead.
This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE`
declaration.

default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.
Follow through with that intent and remove `git_config_get_string()`.
All callsites are adjusted so that they use
`repo_config_get_string(the_repository, ...)` instead. While some
callsites might already have a repository available, this mechanical
conversion is the exact same as the current situation and thus cannot
cause any regression. Those sites should eventually be cleaned up in a
later patch series.
