NAME
git-repack - Pack unpacked objects in a repository
SYNOPSIS
git repack [-a] [-A] [-d] [-f] [-F] [-l] [-n] [-q] [--window=<n>] [--depth=<n>]
DESCRIPTION
This script is used to combine all objects that do not currently reside in a "pack", into a pack. It can also
be used to re-organize existing packs into a single, more efficient pack.
A pack is a collection of objects, individually compressed, with delta compression applied, stored in a single
file, with an associated index file.
Packs are used to reduce the load on mirror systems, backup engines, disk storage, etc.
OPTIONS
-a
Instead of incrementally packing the unpacked objects, pack everything referenced into a single pack.
Especially useful when packing a repository that is used for private development. Use with -d. This will
clean up the objects that git prune leaves behind, but git fsck --full --dangling shows as dangling.
Note that users fetching over dumb protocols will have to fetch the whole new pack in order to get any
contained object, no matter how many other objects in that pack they already have locally.
-A
Same as -a, unless -d is used. Then any unreachable objects in a previous pack become loose, unpacked
objects, instead of being left in the old pack. Unreachable objects are never intentionally added to a
pack, even when repacking. This option prevents unreachable objects from being immediately deleted by way
of being left in the old pack and then removed. Instead, the loose unreachable objects will be pruned
according to normal expiry rules with the next git gc invocation. See git-gc(1).
-d
After packing, if the newly created packs make some existing packs redundant, remove the redundant packs.
Also run git prune-packed to remove redundant loose object files.
-l
Pass the --local option to git pack-objects. See git-pack-objects(1).
-f
Pass the --no-reuse-delta option to git-pack-objects, see git-pack-objects(1).
-F
Pass the --no-reuse-object option to git-pack-objects, see git-pack-objects(1).
-q
Pass the -q option to git pack-objects. See git-pack-objects(1).
-n
Do not update the server information with git update-server-info. This option skips updating local catalog
files needed to publish this repository (or a direct copy of it) over HTTP or FTP. See git-update-server-
info(1).
--window=<n>, --depth=<n>
These two options affect how the objects contained in the pack are stored using delta compression. The
objects are first internally sorted by type, size and optionally names and compared against the other
--max-pack-size=<n>
Maximum size of each output pack file. The size can be suffixed with "k", "m", or "g". The minimum size
allowed is limited to 1 MiB. If specified, multiple packfiles may be created. The default is unlimited,
unless the config variable pack.packSizeLimit is set.
CONFIGURATION
By default, the command passes --delta-base-offset option to git pack-objects; this typically results in
slightly smaller packs, but the generated packs are incompatible with versions of Git older than version
1.4.4. If you need to share your repository with such ancient Git versions, either directly or via the dumb
http or rsync protocol, then you need to set the configuration variable repack.UseDeltaBaseOffset to "false"
and repack. Access from old Git versions over the native protocol is unaffected by this option as the
conversion is performed on the fly as needed in that case.
