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.
With the --split option, write the commit-graph as a chain of multiple commit-graph files stored in <dir>/info/commit-graphs. 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.
