git-multi-pack-index - Write and verify multi-pack-indexes
git multi-pack-index [--object-dir=<dir>] [--[no-]progress] <subcommand>
Write or verify a multi-pack-index (MIDX) file.
Use given directory for the location of Git objects. We
check <dir>/packs/multi-pack-index for the current MIDX file, and
<dir>/packs for the pack-files to index.
Turn progress on/off explicitly. If neither is specified,
progress is shown if standard error is connected to a terminal.
The following subcommands are available:
Write a new MIDX file.
Verify the contents of the MIDX file.
Delete the pack-files that are tracked by the MIDX file,
but have no objects referenced by the MIDX. Rewrite the MIDX file afterward to
remove all references to these pack-files.
Create a new pack-file containing objects in small
pack-files referenced by the multi-pack-index. If the size given by the
argument is zero, then create a pack
containing all objects referenced by the multi-pack-index. For a non-zero
batch size, Select the pack-files by examining packs from oldest-to-newest,
computing the "expected size" 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. We select packs with
expected size below the batch size until the set of packs have total expected
size at least the batch size. If the total size does not reach the batch size,
then do nothing. If a new pack- file is created, rewrite the multi-pack-index
to reference the new pack-file. A later run of git multi-pack-index
will delete the pack-files that were part of this batch.
If repack.packKeptObjects is false, then any
pack-files with an associated .keep file will not be selected for the
batch to repack.
•Write a MIDX file for the packfiles in the
current .git folder.
$ git multi-pack-index write
•Write a MIDX file for the packfiles in an
alternate object store.
$ git multi-pack-index --object-dir <alt> write
•Verify the MIDX file for the packfiles in the
current .git folder.
$ git multi-pack-index verify
