git-commit-graph(1)
===================
NAME
----
git-commit-graph - Write and verify Git commit graph files
SYNOPSIS
--------
[verse]
'git commit-graph read' [--object-dir <dir>]
'git commit-graph verify' [--object-dir <dir>]
'git commit-graph write' <options> [--object-dir <dir>]
DESCRIPTION
-----------
Manage the serialized commit graph file.
OPTIONS
-------
--object-dir::
Use given directory for the location of packfiles and commit graph
file. This parameter exists to specify the location of an alternate
that only has the objects directory, not a full .git directory. The
commit graph file is expected to be at <dir>/info/commit-graph and
the packfiles are expected to be in <dir>/pack.
COMMANDS
--------
'write'::
Write a commit graph file based on the commits found in packfiles.
+
With the `--stdin-packs` option, generate the new commit graph by
walking objects only in the specified pack-indexes. (Cannot be combined
with `--stdin-commits` or `--reachable`.)
+
With the `--stdin-commits` option, generate the new commit graph by
walking commits starting at the commits specified in stdin as a list
of OIDs in hex, one OID per line. (Cannot be combined with
`--stdin-packs` or `--reachable`.)
+
With the `--reachable` option, generate the new commit graph by walking
commits starting at all refs. (Cannot be combined with `--stdin-commits`
or `--stdin-packs`.)
+
With the `--append` option, include all commits that are present in the
existing commit-graph file.
'read'::
Read a graph file given by the commit-graph file and output basic
details about the graph file. Used for debugging purposes.
'verify'::
Read the commit-graph file and verify its contents against the object
database. Used to check for corrupted data.
EXAMPLES
--------
* Write a commit graph file for the packed commits in your local .git folder.
+
------------------------------------------------
$ git commit-graph write
------------------------------------------------
* Write a graph file, extending the current graph file using commits
* in <pack-index>.
+
------------------------------------------------
$ echo <pack-index> | git commit-graph write --stdin-packs
------------------------------------------------
* Write a graph file containing all reachable commits.
+
------------------------------------------------
$ git show-ref -s | git commit-graph write --stdin-commits
------------------------------------------------
* Write a graph file containing all commits in the current
* commit-graph file along with those reachable from HEAD.
+
------------------------------------------------
$ git rev-parse HEAD | git commit-graph write --stdin-commits --append
------------------------------------------------
* Read basic information from the commit-graph file.
+
------------------------------------------------
$ git commit-graph read
------------------------------------------------
