NAME¶git-commit-graph - Write and verify Git commit-graph files
git commit-graph verify [--object-dir <dir>] [--shallow] [--[no-]progress] git commit-graph write <options> [--object-dir <dir>] [--[no-]progress]
DESCRIPTION¶Manage the serialized commit-graph file.
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. OIDs that resolve to non-commits (either directly, or by peeling tags) are silently ignored. OIDs that are malformed, or do not exist generate an error. (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.
With the --changed-paths option, compute and write information about the paths changed between a commit and its first parent. This operation can take a while on large repositories. It provides significant performance gains for getting history of a directory or a file with git log -- <path>.
With the --split[=<strategy>] option, write the commit-graph as a chain of multiple commit-graph files stored in <dir>/info/commit-graphs. Commit-graph layers are merged based on the strategy and other splitting options. The new commits not already in the commit-graph are added in a new "tip" file. This file is merged with the existing file if the following merge conditions are met:
Finally, if --expire-time=<datetime> is not specified, let datetime be the current time. After writing the split commit-graph, delete all unused commit-graph whose modified times are older than datetime.
With the --shallow option, only check the tip commit-graph file in a chain of split commit-graphs.
