NAME
git-pack-refs - Pack heads and tags for efficient
repository access
SYNOPSIS
git-pack-refs [--all] [--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 creates new file under
$GIT_DIR/refs hierarchy.
OPTIONS
- --all
- The command by default packs all tags and leaves branch tips
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.
- --prune
- After packing the refs, remove loose refs under $GIT_DIR/refs
hierarchy. This should probably become default.
