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
.gitdirectory. The commit-graph file is expected to be in the
<dir>/infodirectory 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.
Turn progress on/off explicitly. If neither is specified, progress is shown if standard error is connected to a terminal.
Write a commit-graph file based on the commits found in packfiles. If the config option
core.commitGraphis disabled, then this command will output a warning, then return success without writing a commit-graph file.
--stdin-packsoption, generate the new commit graph by walking objects only in the specified pack-indexes. (Cannot be combined with
--stdin-commitsoption, 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
--reachableoption, generate the new commit graph by walking commits starting at all refs. (Cannot be combined with
--appendoption, include all commits that are present in the existing commit-graph file.
--changed-pathsoption, 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-pathsto stop storing this data.
--max-new-filters=<n>option, generate at most
nnew Bloom filters (if
--changed-pathsis specified). If
-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
--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:
--split=no-mergeis specified, a merge is never performed, and the remaining options are ignored.
--split=replaceoverwrites the existing chain with a new one. A bare
--splitdefers 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).
--size-multiple=<X>is not specified, let
Xequal 2. If the new tip file would have
Ncommits and the previous tip has
Nis greater than
M, instead merge the two files into a single file.
--max-commits=<M>is specified with
Ma positive integer, and the new tip file would have more than
Mcommits, then instead merge the new tip with the previous tip.
--expire-time=<datetime>is not specified, let
datetimebe the current time. After writing the split commit-graph, delete all unused commit-graph whose modified times are older than
Read the commit-graph file and verify its contents against the object database. Used to check for corrupted data.
--shallowoption, only check the tip commit-graph file in a chain of split commit-graphs.
Write a commit-graph file for the packed commits in your local
$ git commit-graph write
Write a commit-graph file, extending the current commit-graph file using commits in
$ 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
$ git rev-parse HEAD | git commit-graph write --stdin-commits --append
Everything below this line in this section is selectively included from the git-config documentation. The content is the same as what’s found there:
Specifies the type of generation number version to use when writing or reading the commit-graph file. If version 1 is specified, then the corrected commit dates will not be written or read. Defaults to 2.
Specifies the default value for the
git commit-graph write(c.f., git-commit-graph).
If true, then git will use the changed-path Bloom filters in the commit-graph file (if it exists, and they are present). Defaults to true. See git-commit-graph for more information.
