|
|
git-repack - Pack unpacked objects in a repository
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-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 gitlink:git-prune-packed[1].
|
|
|
|
-l::
|
|
Pass the `--local` option to `git pack-objects`, see
|
|
gitlink:git-pack-objects[1].
|
|
|
|
-f::
|
|
Pass the `--no-reuse-delta` option to `git pack-objects`, see
|
|
gitlink:git-pack-objects[1].
|
|
|
|
-q::
|
|
Pass the `-q` option to `git pack-objects`, see
|
|
gitlink:git-pack-objects[1].
|
|
|
|
-n::
|
|
Do not update the server information with
|
|
`git update-server-info`.
|
|
|
|
--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).
