GIT-COMMIT-GRAPH(1)

NAME
git-commit-graph - Write and verify Git commit graph files

SYNOPSIS

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
