    Command:

    git-repack

    
    
    

    SYNOPSIS

           git repack [-a] [-A] [-d] [-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 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-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).
               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.
