NAME

----
|
|
git-pack-refs - Pack heads and tags for efficient repository access
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git pack-refs' [--all] [--no-prune]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Traditionally, tips of branches and tags (collectively known as
|
|
'refs') were stored one file per ref under `$GIT_DIR/refs`
|
|
directory. While many branch tips tend to be updated often,
|
|
most tags and some branch tips are never updated. When a
|
|
repository has hundreds or thousands of tags, this
|
|
one-file-per-ref format both wastes storage and hurts
|
|
performance.
|
|
|
|
This command is used to solve the storage and performance
|
|
problem by stashing the refs in a single file,
|
|
`$GIT_DIR/packed-refs`. When a ref is missing from the
|
|
traditional `$GIT_DIR/refs` hierarchy, it is looked up in this
|
|
file and used if found.
|
|
|
|
Subsequent updates to branches always create new files under
|
|
`$GIT_DIR/refs` hierarchy.
|
|
|
|
A recommended practice to deal with a repository with too many
|
|
refs is to pack its refs with `--all --prune` once, and
|
|
occasionally run `git pack-refs \--prune`. Tags are by
|
|
definition stationary and are not expected to change. Branch
|
|
heads will be packed with the initial `pack-refs --all`, but
|
|
only the currently active branch heads will become unpacked,
|
|
and the next `pack-refs` (without `--all`) will leave them
|
|
unpacked.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--all::
|
|
|
|
The command by default packs all tags and refs that are already
|
|
packed, and leaves other refs
|
|
alone. This is because branches are expected to be actively
|
|
developed and packing their tips does not help performance.
|
|
This option causes branch tips to be packed as well. Useful for
|
|
a repository with many branches of historical interests.
|
|
|
|
--no-prune::
|
|
|
|
The command usually removes loose refs under `$GIT_DIR/refs`
|
|
hierarchy after packing them. This option tells it not to.
