 807 Write a commit-graph file based on the commits found in packfiles. If
 808 the config option <code>core.commitGraph</code> is disabled, then this command will
 809 output a warning, then return success without writing a commit-graph file.
 810 </p>
 811 <div class="paragraph"><p>With the <code>--stdin-packs</code> option, generate the new commit graph by
 812 walking objects only in the specified pack-indexes. (Cannot be combined
 813 with <code>--stdin-commits</code> or <code>--reachable</code>.)</p></div>
 814 <div class="paragraph"><p>With the <code>--stdin-commits</code> option, generate the new commit graph by
 815 walking commits starting at the commits specified in stdin as a list
 816 of OIDs in hex, one OID per line. OIDs that resolve to non-commits
 817 (either directly, or by peeling tags) are silently ignored. OIDs that
 818 are malformed, or do not exist generate an error. (Cannot be combined
 819 with <code>--stdin-packs</code> or <code>--reachable</code>.)</p></div>
 820 <div class="paragraph"><p>With the <code>--reachable</code> option, generate the new commit graph by walking
 821 commits starting at all refs. (Cannot be combined with <code>--stdin-commits</code>
 822 or <code>--stdin-packs</code>.)</p></div>
 823 <div class="paragraph"><p>With the <code>--append</code> option, include all commits that are present in the
 824 existing commit-graph file.</p></div>
 825 <div class="paragraph"><p>With the <code>--changed-paths</code> option, compute and write information about the
 826 paths changed between a commit and its first parent. This operation can
 827 take a while on large repositories. It provides significant performance gains
 828 for getting history of a directory or a file with <code>git log -- &lt;path&gt;</code>. If
 829 this option is given, future commit-graph writes will automatically assume
 830 that this option was intended. Use <code>--no-changed-paths</code> to stop storing this
 831 data.</p></div>
 832 <div class="paragraph"><p>With the <code>--max-new-filters=&lt;n&gt;</code> option, generate at most <code>n</code> new Bloom
 833 filters (if <code>--changed-paths</code> is specified). If <code>n</code> is <code>-1</code>, no limit is
 834 enforced. Only commits present in the new layer count against this
 835 limit. To retroactively compute Bloom filters over earlier layers, it is
 836 advised to use <code>--split=replace</code>.  Overrides the <code>commitGraph.maxNewFilters</code>
 837 configuration.</p></div>
 838 <div class="paragraph"><p>With the <code>--split[=&lt;strategy&gt;]</code> option, write the commit-graph as a
 839 chain of multiple commit-graph files stored in
 840 <code>&lt;dir&gt;/info/commit-graphs</code>. Commit-graph layers are merged based on the
 841 strategy and other splitting options. The new commits not already in the
 842 commit-graph are added in a new "tip" file. This file is merged with the
 843 existing file if the following merge conditions are met:</p></div>
 844 <div class="ulist"><ul>
 845 <li>
 846 <p>
 847 If <code>--split=no-merge</code> is specified, a merge is never performed, and
 848 the remaining options are ignored. <code>--split=replace</code> overwrites the
 849 existing chain with a new one. A bare <code>--split</code> defers to the remaining
 850 options. (Note that merging a chain of commit graphs replaces the
 851 existing chain with a length-1 chain where the first and only
 852 incremental holds the entire graph).
 853 </p>
 854 </li>
 855 <li>
 856 <p>
 857 If <code>--size-multiple=&lt;X&gt;</code> is not specified, let <code>X</code> equal 2. If the new
 858 tip file would have <code>N</code> commits and the previous tip has <code>M</code> commits and
 859 <code>X</code> times <code>N</code> is greater than  <code>M</code>, instead merge the two files into a
 860 single file.
 861 </p>
 862 </li>
 863 <li>
 864 <p>
 865 If <code>--max-commits=&lt;M&gt;</code> is specified with <code>M</code> a positive integer, and the
 866 new tip file would have more than <code>M</code> commits, then instead merge the new
 867 tip with the previous tip.
 868 </p>
 869 <div class="paragraph"><p>Finally, if <code>--expire-time=&lt;datetime&gt;</code> is not specified, let <code>datetime</code>
 870 be the current time. After writing the split commit-graph, delete all
 871 unused commit-graph whose modified times are older than <code>datetime</code>.</p></div>
