GIT-REPACK(1)                                    Git Manual                                    GIT-REPACK(1)



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 objects within --window to see if using delta compression saves space.
           --depth limits the maximum delta depth; making it too deep affects the performance on the
           unpacker side, because delta data needs to be applied that many times to get to the necessary
           object. The default value for --window is 10 and --depth is 50.

       --window-memory=<n>
           This option provides an additional limit on top of --window; the window size will dynamically
           scale down so as to not take up more than <n> bytes in memory. This is useful in repositories
           with a mix of large and small objects to not run out of memory with a large window, but still be
           able to take advantage of the large window for the smaller objects. The size can be suffixed with
           "k", "m", or "g".  --window-memory=0 makes memory usage unlimited, which is the default.

       --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.
