|
|
git-pack-objects - Create a packed archive of objects.
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-pack-objects' [--local] [--incremental] [--window=N] [--depth=N] {--stdout | base-name} < object-list
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Reads list of objects from the standard input, and writes a packed
|
|
archive with specified base-name, or to the standard output.
|
|
|
|
A packed archive is an efficient way to transfer set of objects
|
|
between two repositories, and also is an archival format which
|
|
is efficient to access. The packed archive format (.pack) is
|
|
designed to be unpackable without having anything else, but for
|
|
random access, accompanied with the pack index file (.idx).
|
|
|
|
'git-unpack-objects' command can read the packed archive and
|
|
expand the objects contained in the pack into "one-file
|
|
one-object" format; this is typically done by the smart-pull
|
|
commands when a pack is created on-the-fly for efficient network
|
|
transport by their peers.
|
|
|
|
Placing both in the pack/ subdirectory of $GIT_OBJECT_DIRECTORY (or
|
|
any of the directories on $GIT_ALTERNATE_OBJECT_DIRECTORIES)
|
|
enables git to read from such an archive.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
base-name::
|
|
Write into a pair of files (.pack and .idx), using
|
|
<base-name> to determine the name of the created file.
|
|
When this option is used, the two files are written in
|
|
<base-name>-<SHA1>.{pack,idx} files. <SHA1> is a hash
|
|
of object names (currently in random order so it does
|
|
not have any useful meaning) to make the resulting
|
|
filename reasonably unique, and written to the standard
|
|
output of the command.
|
|
|
|
--stdout::
|
|
Write the pack contents (what would have been writtin to
|
|
.pack file) out to the standard output.
|
|
|
|
--window and --depth::
|
|
These two options affects 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.
|
|
|
|
--incremental::
|
|
This flag causes an object already in a pack ignored
|
|
even if it appears in the standard input.
|
|
|
|
--local::
|
|
This flag is similar to `--incremental`; instead of
|
|
ignoring all packed objects, it only ignores objects
|
|
that are packed and not in the local object store
|
|
(i.e. borrowed from an alternate).
