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 in the `<dir>/info` directory and - the packfiles are expected to be in `<dir>/pack`. If the directory - could not be made into an absolute path, or does not match any known - object directory, `git commit-graph ...` will exit with non-zero - status. - ---[no-]progress:: - Turn progress on/off explicitly. If neither is specified, progress is - shown if standard error is connected to a terminal. - -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. 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>`. If -this option is given, future commit-graph writes will automatically assume -that this option was intended. Use `--no-changed-paths` to stop storing this -data. -+ -With the `--max-new-filters=<n>` option, generate at most `n` new Bloom -filters (if `--changed-paths` is specified). If `n` is `-1`, no limit is -enforced. Only commits present in the new layer count against this -limit. To retroactively compute Bloom filters over earlier layers, it is -advised to use `--split=replace`. Overrides the `commitGraph.maxNewFilters` -configuration. -+ -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: -+ -* If `--split=no-merge` is specified, a merge is never performed, and -the remaining options are ignored. `--split=replace` overwrites the -existing chain with a new one. A bare `--split` defers to the remaining -options. (Note that merging a chain of commit graphs replaces the -existing chain with a length-1 chain where the first and only -incremental holds the entire graph). -+ -* If `--size-multiple=<X>` is not specified, let `X` equal 2. If the new -tip file would have `N` commits and the previous tip has `M` commits and -`X` times `N` is greater than `M`, instead merge the two files into a -single file. -+ -* If `--max-commits=<M>` is specified with `M` a positive integer, and the -new tip file would have more than `M` commits, then instead merge the new -tip with the previous tip. -+ -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`. - -'verify':: - -Read the commit-graph file and verify its contents against the object -database. Used to check for corrupted data. -+ -With the `--shallow` option, only check the tip commit-graph file in -a chain of split commit-graphs. - - -EXAMPLES --------- - -* 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 ------------------------------------------------- - - -GIT ---- -Part of the linkgit:git[1] suite |
