git commit-graph read [--object-dir <dir>] git commit-graph verify [--object-dir <dir>] git commit-graph write <options> [--object-dir <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.
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 the commit-graph file and output basic details about it. Used for debugging purposes.verify
Read the commit-graph file and verify its contents against the object database. Used to check for corrupted data.
•Write a commit-graph file for the packed commits in your local .git directory.
$ git commit-graph write
•Write a commit-graph file, extending the current commit-graph file using commits in <pack-index>.
$ echo <pack-index> | git commit-graph write --stdin-packs
•Write a commit-graph file containing all reachable commits.
$ git show-ref -s | git commit-graph write --stdin-commits
•Write a commit-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
