git-multi-pack-index - Write and verify multi-pack-indexes
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git multi-pack-index' [--object-dir=<dir>] [--[no-]bitmap] <sub-command>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Write or verify a multi-pack-index (MIDX) file.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--object-dir=<dir>::
|
|
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.
|
|
+
|
|
`<dir>` must be an alternate of the current repository.
|
|
|
|
--[no-]progress::
|
|
Turn progress on/off explicitly. If neither is specified, progress is
|
|
shown if standard error is connected to a terminal. Supported by
|
|
sub-commands `write`, `verify`, `expire`, and `repack.
|
|
|
|
The following subcommands are available:
|
|
|
|
write::
|
|
Write a new MIDX file. The following options are available for
|
|
the `write` sub-command:
|
|
+
|
|
--
|
|
--preferred-pack=<pack>::
|
|
Optionally specify the tie-breaking pack used when
|
|
multiple packs contain the same object. `<pack>` must
|
|
contain at least one object. If not given, ties are
|
|
broken in favor of the pack with the lowest mtime.
|
|
|
|
--[no-]bitmap::
|
|
Control whether or not a multi-pack bitmap is written.
|
|
|
|
--stdin-packs::
|
|
Write a multi-pack index containing only the set of
|
|
line-delimited pack index basenames provided over stdin.
|
|
|
|
--refs-snapshot=<path>::
|
|
With `--bitmap`, optionally specify a file which
|
|
contains a "refs snapshot" taken prior to repacking.
|
|
+
|
|
A reference snapshot is composed of line-delimited OIDs corresponding to
|
|
the reference tips, usually taken by `git repack` prior to generating a
|
|
new pack. A line may optionally start with a `+` character to indicate
|
|
that the reference which corresponds to that OID is "preferred" (see
|
|
linkgit:git-config[1]'s `pack.preferBitmapTips`.)
|
|
+
|
|
The file given at `<path>` is expected to be readable, and can contain
|
|
duplicates. (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 `+`
|
|
marker).
|
|
--
|
|
|
|
verify::
|
|
Verify the contents of the MIDX file.
|
|
|
|
expire::
|
|
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.
|
|
|
|
repack::
|
|
Create a new pack-file containing objects in small pack-files
|
|
referenced by the multi-pack-index. If the size given by the
|
|
`--batch-size=<size>` 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, or all pack-files
|
|
are considered. If only one pack-file is selected, 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 expire' 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.
|
|
|

EXAMPLES
|
|
--------
|
|
|
|
* Write a MIDX file for the packfiles in the current `.git` directory.
|
|
+
|
|
-----------------------------------------------
|
|
$ git multi-pack-index write
|
|
-----------------------------------------------
|
|
|
|
* Write a MIDX file for the packfiles in the current `.git` directory with a
|
|
corresponding bitmap.
|
|
+
|
|
-------------------------------------------------------------
|
|
$ git multi-pack-index write --preferred-pack=<pack> --bitmap
|
|
-------------------------------------------------------------
|
|
|
|
* 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` directory.
