--object-dir

<DL COMPACT><DT id="1"><DD>

|
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
|
|
<B>.git</B>
|
|
directory. The commit-graph file is expected to be in the
|
|
<B><dir>/info</B>
|
|
directory and the packfiles are expected to be in
|
|
<B><dir>/pack</B>.

</DL>
|

<P>
|
|
|

--[no-]progress

<DL COMPACT><DT id="2"><DD>

Turn progress on/off explicitly. If neither is specified, progress is shown if standard error is connected to a terminal.

<DL COMPACT><DT id="3"><DD>
|
|
Write a commit-graph file based on the commits found in packfiles.
|
|
<P>
|
|
With the
|
|
<B>--stdin-packs</B>
|
|
option, generate the new commit graph by walking objects only in the specified pack-indexes. (Cannot be combined with
|
|
<B>--stdin-commits</B>
|
|
or
|
|
<B>--reachable</B>.)
|
|
<P>
|
|
With the
|
|
<B>--stdin-commits</B>
|
|
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
|
|
<B>--stdin-packs</B>
|
|
or
|
|
<B>--reachable</B>.)
|
|
<P>
|
|
With the
|
|
<B>--reachable</B>
|
|
option, generate the new commit graph by walking commits starting at all refs. (Cannot be combined with
|
|
<B>--stdin-commits</B>
|
|
or
|
|
<B>--stdin-packs</B>.)
|
|
<P>
|
|
With the
|
|
<B>--append</B>
|
|
option, include all commits that are present in the existing commit-graph file.
|
|
<P>
|
|
With the
|
|
<B>--split</B>
|
|
option, write the commit-graph as a chain of multiple commit-graph files stored in
|
|
<B><dir>/info/commit-graphs</B>. 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

<B>--size-multiple=<X></B>

is not specified, let

<B>X</B>
|

equal 2. If the new tip file would have
|
|
<B>N</B>
|

commits and the previous tip has

<B>M</B>

commits and
|

<B>X</B>

times
|
|
<B>N</B>

<B>M</B>, instead merge the two files into a single file.

If

<B>--max-commits=<M></B>

is specified with
|

<B>M</B>
|
|
a positive integer, and the new tip file would have more than
|
|
<B>M</B>
|
|
commits, then instead merge the new tip with the previous tip.
|
|
<P>
|
|
Finally, if
|
|
<B>--expire-time=<datetime></B>
|
|
is not specified, let
|
|
<B>datetime</B>

be the current time. After writing the split commit-graph, delete all unused commit-graph whose modified times are older than

<B>datetime</B>.
