NAME¶
git-repack - Pack unpacked objects in a repositorySYNOPSIS¶
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.OPTIONS¶
-aInstead 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.SEE ALSO¶
