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.
|
|
|
|
|
|
|
|
|
|
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 available 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 file transfer protocols
|
|
|
|
|
from it. Use with '-d'.
|
|
|
|
|
|
|
|
|
|
-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 both --window and --depth is 10.
|
|
|

|
|
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).
