git-multi-pack-index \- Write and verify multi\-pack\-indexes
.SH &quot;SYNOPSIS&quot;
.sp
.nf
\fIgit multi\-pack\-index\fR [\-\-object\-dir=&lt;dir&gt;] [\-\-[no\-]bitmap] &lt;sub\-command&gt;
.fi
.sp
.SH &quot;DESCRIPTION&quot;
.sp
Write or verify a multi\-pack\-index (MIDX) file\&amp;.
.SH &quot;OPTIONS&quot;
.PP
\-\-object\-dir=&lt;dir&gt;
.RS 4
Use given directory for the location of Git objects\&amp;. We check
\fI&lt;dir&gt;\fR\fB/packs/multi\-pack\-index\fR
for the current MIDX file, and
\fI&lt;dir&gt;\fR\fB/packs\fR
for the pack\-files to index\&amp;.
.sp
\fI&lt;dir&gt;\fR
must be an alternate of the current repository\&amp;.
.RE
.PP
\-\-[no\-]progress
.RS 4
Turn progress on/off explicitly\&amp;. If neither is specified, progress is shown if standard error is connected to a terminal\&amp;. Supported by sub\-commands
\fBwrite\fR,
\fBverify\fR,
\fBexpire\fR, and `repack\&amp;.
.RE
.sp
The following subcommands are available:
.PP
write
.RS 4
Write a new MIDX file\&amp;. The following options are available for the
\fBwrite\fR
sub\-command:
.PP
\-\-preferred\-pack=&lt;pack&gt;
.RS 4
Optionally specify the tie\-breaking pack used when multiple packs contain the same object\&amp;.
\fI&lt;pack&gt;\fR
must contain at least one object\&amp;. If not given, ties are broken in favor of the pack with the lowest mtime\&amp;.
.RE
.PP
\-\-[no\-]bitmap
.RS 4
Control whether or not a multi\-pack bitmap is written\&amp;.
.RE
.PP
\-\-stdin\-packs
.RS 4
Write a multi\-pack index containing only the set of line\-delimited pack index basenames provided over stdin\&amp;.
.RE
.PP
\-\-refs\-snapshot=&lt;path&gt;
.RS 4
With
\fB\-\-bitmap\fR, optionally specify a file which contains a &quot;refs snapshot&quot; taken prior to repacking\&amp;.
.sp
A reference snapshot is composed of line\-delimited OIDs corresponding to the reference tips, usually taken by
\fBgit\fR
\fBrepack\fR
prior to generating a new pack\&amp;. A line may optionally start with a
\fB+\fR
character to indicate that the reference which corresponds to that OID is &quot;preferred&quot; (see
\fBgit-config\fR(1)\*(Aqs
\fBpack\&amp;.preferBitmapTips\fR\&amp;.)
.sp
The file given at
\fI&lt;path&gt;\fR
is expected to be readable, and can contain duplicates\&amp;. (If a given OID is given more than once, it is marked as preferred if at least one instance of it begins with the special
\fB+\fR
marker)\&amp;.
.RE
.PP
\-\-incremental
.RS 4
Write an incremental MIDX file containing only objects and packs not present in an existing MIDX layer\&amp;. Migrates non\-incremental MIDXs to incremental ones when necessary\&amp;. Incompatible with
\fB\-\-bitmap\fR\&amp;.
.RE
.RE
.PP
verify
.RS 4
Verify the contents of the MIDX file\&amp;.
.RE
.PP
expire
.RS 4
Delete the pack\-files that are tracked by the MIDX file, but have no objects referenced by the MIDX (with the exception of
\fB\&amp;.keep\fR
packs and cruft packs)\&amp;. Rewrite the MIDX file afterward to remove all references to these pack\-files\&amp;.

this mode is incompatible with incremental MIDX files\&amp;.
.sp .5v
.RE
.RE
.PP
repack
.RS 4
Create a new pack\-file containing objects in small pack\-files referenced by the multi\-pack\-index\&amp;. If the size given by the
\fB\-\-batch\-size=\fR\fI&lt;size&gt;\fR
argument is zero, then create a pack containing all objects referenced by the multi\-pack\-index\&amp;. For a non\-zero batch size, Select the pack\-files by examining packs from oldest\-to\-newest, computing the &quot;expected size&quot; by counting the number of objects in the pack referenced by the multi\-pack\-index, then divide by the total number of objects in the pack and multiply by the pack size\&amp;. We select packs with expected size below the batch size until the set of packs have total expected size at least the batch size, or all pack\-files are considered\&amp;. If only one pack\-file is selected, then do nothing\&amp;. If a new pack\-file is created, rewrite the multi\-pack\-index to reference the new pack\-file\&amp;. A later run of
\fIgit multi\-pack\-index expire\fR
will delete the pack\-files that were part of this batch\&amp;.
.sp
If
\fBrepack\&amp;.packKeptObjects\fR
is
\fBfalse\fR, then any pack\-files with an associated
\fB\&amp;.keep\fR
file will not be selected for the batch to repack\&amp;.
