6 git-multi-pack-index - Write and verify multi-pack-indexes
12 'git multi-pack-index' [--object-dir=<dir>] [--[no-]progress] <subcommand>
16 Write or verify a multi-pack-index (MIDX) file.
22 Use given directory for the location of Git objects. We check
23 `<dir>/packs/multi-pack-index` for the current MIDX file, and
24 `<dir>/packs` for the pack-files to index.
27 Turn progress on/off explicitly. If neither is specified, progress is
28 shown if standard error is connected to a terminal.
30 The following subcommands are available:
33 Write a new MIDX file.
36 Verify the contents of the MIDX file.
39 Delete the pack-files that are tracked by the MIDX file, but
40 have no objects referenced by the MIDX. Rewrite the MIDX file
41 afterward to remove all references to these pack-files.
44 Create a new pack-file containing objects in small pack-files
45 referenced by the multi-pack-index. If the size given by the
46 `--batch-size=<size>` argument is zero, then create a pack
47 containing all objects referenced by the multi-pack-index. For
48 a non-zero batch size, Select the pack-files by examining packs
49 from oldest-to-newest, computing the "expected size" by counting
50 the number of objects in the pack referenced by the
51 multi-pack-index, then divide by the total number of objects in
52 the pack and multiply by the pack size. We select packs with
53 expected size below the batch size until the set of packs have
54 total expected size at least the batch size. If the total size
55 does not reach the batch size, then do nothing. If a new pack-
56 file is created, rewrite the multi-pack-index to reference the
57 new pack-file. A later run of 'git multi-pack-index expire' will
58 delete the pack-files that were part of this batch.
64 * Write a MIDX file for the packfiles in the current .git folder.

67 $ git multi-pack-index write

70 * Write a MIDX file for the packfiles in an alternate object store.

76 * Verify the MIDX file for the packfiles in the current .git folder.
