GIT-REPACK(1) Git Manual GIT-REPACK(1)NAMEgit-repack - Pack unpacked objects in a repository
SYNOPSISgit-repack [-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 and
there is no need to worry about people fetching via dumb
protocols from it. Use with -d. This will clean up the objects
that git prune leaves behind, but git fsck --full shows as
dangling.
-d After packing, if the newly created packs make some existing
packs redundant, remove the redundant packs. Also runs
git-prune-packed(1).
-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).
-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[1]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 packfile, expressed in MiB. If
specified, multiple packfiles may be created. The default is
unlimited.
CONFIGURATION
When configuration variable repack.UseDeltaBaseOffset is set for the
repository, 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
(and including) v1.4.3; do not set the variable in a repository that
older version of git needs to be able to read (this includes
repositories from which packs can be copied out over http or rsync, and
people who obtained packs that way can try to use older git with it).
