<p>
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 <code>.git</code> directory. The
commit-graph file is expected to be in the <code><dir>/info</code> directory and
the packfiles are expected to be in <code><dir>/pack</code>. If the directory
could not be made into an absolute path, or does not match any known
object directory, <code>git commit-graph ...</code> will exit with non-zero
status.
</p>
</dd>
<dt class="hdlist1">
--[no-]progress
</dt>
<dd>
<p>
Turn progress on/off explicitly. If neither is specified, progress is
shown if standard error is connected to a terminal.

<h2 id="_commands">COMMANDS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
<em>write</em>
</dt>
<dd>
<p>
Write a commit-graph file based on the commits found in packfiles. If
the config option <code>core.commitGraph</code> is disabled, then this command will
output a warning, then return success without writing a commit-graph file.
</p>
<div class="paragraph"><p>With the <code>--stdin-packs</code> option, generate the new commit graph by
walking objects only in the specified pack-indexes. (Cannot be combined
with <code>--stdin-commits</code> or <code>--reachable</code>.)</p></div>
<div class="paragraph"><p>With the <code>--stdin-commits</code> 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 <code>--stdin-packs</code> or <code>--reachable</code>.)</p></div>
<div class="paragraph"><p>With the <code>--reachable</code> option, generate the new commit graph by walking
commits starting at all refs. (Cannot be combined with <code>--stdin-commits</code>
or <code>--stdin-packs</code>.)</p></div>
<div class="paragraph"><p>With the <code>--append</code> option, include all commits that are present in the
existing commit-graph file.</p></div>
<div class="paragraph"><p>With the <code>--changed-paths</code> 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 <code>git log -- <path></code>. If
this option is given, future commit-graph writes will automatically assume
that this option was intended. Use <code>--no-changed-paths</code> to stop storing this
data.</p></div>
<div class="paragraph"><p>With the <code>--max-new-filters=<n></code> option, generate at most <code>n</code> new Bloom
filters (if <code>--changed-paths</code> is specified). If <code>n</code> is <code>-1</code>, 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 <code>--split=replace</code>. Overrides the <code>commitGraph.maxNewFilters</code>
configuration.</p></div>
<div class="paragraph"><p>With the <code>--split[=<strategy>]</code> option, write the commit-graph as a
chain of multiple commit-graph files stored in
<code><dir>/info/commit-graphs</code>. 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:</p></div>
<div class="ulist"><ul>
<li>
<p>
If <code>--split=no-merge</code> is specified, a merge is never performed, and
the remaining options are ignored. <code>--split=replace</code> overwrites the
existing chain with a new one. A bare <code>--split</code> 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).
</p>
</li>
<li>
<p>
If <code>--size-multiple=<X></code> is not specified, let <code>X</code> equal 2. If the new
tip file would have <code>N</code> commits and the previous tip has <code>M</code> commits and
<code>X</code> times <code>N</code> is greater than <code>M</code>, instead merge the two files into a
single file.
</p>
</li>
<li>
<p>
If <code>--max-commits=<M></code> is specified with <code>M</code> a positive integer, and the
new tip file would have more than <code>M</code> commits, then instead merge the new
tip with the previous tip.
</p>
<div class="paragraph"><p>Finally, if <code>--expire-time=<datetime></code> is not specified, let <code>datetime</code>
be the current time. After writing the split commit-graph, delete all
unused commit-graph whose modified times are older than <code>datetime</code>.</p></div>
</li>
</ul></div>
</dd>
<dt class="hdlist1">
<em>verify</em>
</dt>
<dd>
<p>
Read the commit-graph file and verify its contents against the object
database. Used to check for corrupted data.
</p>
<div class="paragraph"><p>With the <code>--shallow</code> option, only check the tip commit-graph file in
a chain of split commit-graphs.</p></div>
