git-commit-graph - Write and verify Git commit-graph files
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git commit-graph read' [--object-dir <dir>]
|
|
'git commit-graph verify' [--object-dir <dir>] [--shallow]
|
|
'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 in the `<dir>/info` directory 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.
|
|
+
|
|
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:
|
|
+
|
|
* 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`.
|
|
|
|
'read'::
|
|
|
|
Read the commit-graph file and output basic details about it.
|
|
Used for debugging purposes.
|
|
|
|
'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
|
|
------------------------------------------------
|
|
|
|
* Read basic information from the commit-graph file.
|
|
+
|
|
------------------------------------------------
|
|
$ git commit-graph read
