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 in a (sub)directory 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 storing the refs in a single file, $GIT_DIR/packed-refs. When a ref is missing from the traditional $GIT_DIR/refs directory hierarchy, it is looked up in this file and used if found.

Subsequent updates to branches always create new files under $GIT_DIR/refs directory 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

--no-prune

BUGS¶

Older documentation written before the packed-refs mechanism was introduced may still say things like ".git/refs/heads/<branch> file exists" when it means "branch <branch> exists".
