The amount of objects in a repository can provide insight regarding its
shape. To surface this information, use the path-walk API to count the
number of reachable objects in the repository by object type. All
regular references are used to determine the reachable set of objects.
The object counts are appended to the same table containing the
reference information.

The structure of a repository's history can have huge impacts on the
performance and health of the repository itself. Currently, Git lacks a
means to surface repository metrics regarding its structure/shape via a
single command. Acquiring this information requires users to be familiar
with the relevant data points and the various Git commands required to
surface them. To fill this gap, supplemental tools such as git-sizer(1)
have been developed.
To allow users to more readily identify repository structure related
information, introduce the "structure" subcommand in git-repo(1). The
goal of this subcommand is to eventually provide similar functionality
to git-sizer(1), but natively in Git.
The initial version of this command only iterates through all references
in the repository and tracks the count of branches, tags, remote refs,
and other reference types. The corresponding information is displayed in
a human-friendly table formatted in a very similar manner to
git-sizer(1). The width of each table column is adjusted automatically
to satisfy the requirements of the widest row contained.
Subsequent commits will surface additional relevant data points to
output and also provide other more machine-friendly output formats.

After a partial stash, we may clear out the working tree by capturing
the output of diff-tree and piping it into git-apply (and likewise we
may use diff-index to restore the index). So we most definitely do not
want color diff output from that diff-tree process. And it normally
would not produce any, since its stdout is not going to a tty, and the
default value of color.ui is "auto".
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

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

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,

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

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

$ 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

Add the --format flag to git-repo-info. By using this flag, the users

Given that this command can be used for generating input for other

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.

This commit is part of the series that introduces the new subcommand
git-repo-info.
The flag `--is-shallow-repository` from git-rev-parse is used for
retrieving whether the repository is shallow. This way, it is used for
querying repository metadata, fitting in the purpose of git-repo-info.
Then, add a new field `layout.shallow` to the git-repo-info subcommand
containing that information.

This commit is part of the series that introduces the new subcommand
git-repo-info.
The flag --is-bare-repository from git-rev-parse is used for retrieving
whether the current repository is bare. This way, it is used for
querying repository metadata, fitting in the purpose of git-repo-info.
Then, add a new field layout.bare to the git-repo-info subcommand
containing that information.

This commit is part of the series that introduces the new subcommand
git-repo-info.
The flag `--show-ref-format` from git-rev-parse is used for retrieving
the reference format (i.e. `files` or `reftable`). This way, it is
used for querying repository metadata, fitting in the purpose of
git-repo-info.
Add a new field `references.format` to the repo-info subcommand
containing that information.

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`.
Add the required documentation and build changes to enable usage of
this subcommand.
