    Pack heads and tags for efficient repository access

 <div class="sect1">
 <h2 id="_description">DESCRIPTION</h2>
 <div class="sectionbody">
 <div class="paragraph"><p>Traditionally, tips of branches and tags (collectively known as
 <em>refs</em>) were stored one file per ref in a (sub)directory
 under <code>$GIT_DIR/refs</code>
 directory.  While many branch tips tend to be updated often,
 most tags and some branch tips are never updated.  When a
 repository has hundreds or thousands of tags, this
 one-file-per-ref format both wastes storage and hurts
 performance.</p></div>
 <div class="paragraph"><p>This command is used to solve the storage and performance
 problem by storing the refs in a single file,
 <code>$GIT_DIR/packed-refs</code>.  When a ref is missing from the
 traditional <code>$GIT_DIR/refs</code> directory hierarchy, it is looked
 up in this
 file and used if found.</p></div>
 <div class="paragraph"><p>Subsequent updates to branches always create new files under
 <code>$GIT_DIR/refs</code> directory hierarchy.</p></div>
 <div class="paragraph"><p>A recommended practice to deal with a repository with too many
 refs is to pack its refs with <code>--all</code> once, and
 occasionally run <code>git pack-refs</code>.  Tags are by
 definition stationary and are not expected to change.  Branch
 heads will be packed with the initial <code>pack-refs --all</code>, but
 only the currently active branch heads will become unpacked,
 and the next <code>pack-refs</code> (without <code>--all</code>) will leave them
 unpacked.</p></div>
 </div>
 </div>
 <div class="sect1">
 <h2 id="_options">OPTIONS</h2>
 <div class="sectionbody">
 <div class="dlist"><dl>
 <dt class="hdlist1">
 --all
 </dt>
 <dd>
 <p>
 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.
 </p>
 </dd>
 <dt class="hdlist1">
 --no-prune
 </dt>
 <dd>
 <p>
 The command usually removes loose refs under <code>$GIT_DIR/refs</code>
 hierarchy after packing them.  This option tells it not to.
 </p>
 </dd>

 </div>
 <div class="sect1">
 <h2 id="_bugs">BUGS</h2>
 <div class="sectionbody">
 <div class="paragraph"><p>Older documentation written before the packed-refs mechanism was
 introduced may still say things like ".git/refs/heads/&lt;branch&gt; file
 exists" when it means "branch &lt;branch&gt; exists".</p></div>

	<div class="sectionbody">
	<div class="paragraph"><p>Traditionally, tips of branches and tags (collectively known as
	<em>refs</em>) were stored one file per ref in a (sub)directory
	under <code>$GIT_DIR/refs</code>
	directory. While many branch tips tend to be updated often,
	most tags and some branch tips are never updated. When a
	repository has hundreds or thousands of tags, this
	one-file-per-ref format both wastes storage and hurts
	performance.</p></div>
	<div class="paragraph"><p>This command is used to solve the storage and performance
	problem by storing the refs in a single file,
	<code>$GIT_DIR/packed-refs</code>. When a ref is missing from the
	traditional <code>$GIT_DIR/refs</code> directory hierarchy, it is looked
	up in this
	file and used if found.</p></div>
	<div class="paragraph"><p>Subsequent updates to branches always create new files under
	<code>$GIT_DIR/refs</code> directory hierarchy.</p></div>
	<div class="paragraph"><p>A recommended practice to deal with a repository with too many
	refs is to pack its refs with <code>--all</code> once, and
	occasionally run <code>git pack-refs</code>. Tags are by
	definition stationary and are not expected to change. Branch
	heads will be packed with the initial <code>pack-refs --all</code>, but
	only the currently active branch heads will become unpacked,
	and the next <code>pack-refs</code> (without <code>--all</code>) will leave them
	unpacked.</p></div>

	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.

	The command usually removes loose refs under <code>$GIT_DIR/refs</code>
	hierarchy after packing them. This option tells it not to.
