NAME

SYNOPSIS

9       git multi-pack-index [--object-dir=<dir>] <subcommand>
10
11

DESCRIPTION

13       Write or verify a multi-pack-index (MIDX) file.
14

OPTIONS

16       --object-dir=<dir>
17           Use given directory for the location of Git objects. We check
18           <dir>/packs/multi-pack-index for the current MIDX file, and
19           <dir>/packs for the pack-files to index.
20
21       The following subcommands are available:
22
23       write
24           Write a new MIDX file.
25
26       verify
27           Verify the contents of the MIDX file.
28
29       expire
30           Delete the pack-files that are tracked by the MIDX file, but have
31           no objects referenced by the MIDX. Rewrite the MIDX file afterward
32           to remove all references to these pack-files.
33
34       repack
35           Create a new pack-file containing objects in small pack-files
36           referenced by the multi-pack-index. If the size given by the
37           --batch-size=<size> argument is zero, then create a pack containing
38           all objects referenced by the multi-pack-index. For a non-zero
39           batch size, Select the pack-files by examining packs from
40           oldest-to-newest, computing the "expected size" by counting the
41           number of objects in the pack referenced by the multi-pack-index,
42           then divide by the total number of objects in the pack and multiply
43           by the pack size. We select packs with expected size below the
44           batch size until the set of packs have total expected size at least
45           the batch size. If the total size does not reach the batch size,
46           then do nothing. If a new pack- file is created, rewrite the
47           multi-pack-index to reference the new pack-file. A later run of git
48           multi-pack-index expire will delete the pack-files that were part
49           of this batch.
