1611<div class="sectionbody">
1612<div class="paragraph"><p>Git has a default disposition of keeping data unless it&#8217;s explicitly
1613thrown away; this extends to holding onto local references to branches
1614on remotes that have themselves deleted those branches.</p></div>
1615<div class="paragraph"><p>If left to accumulate, these stale references might make performance
1616worse on big and busy repos that have a lot of branch churn, and
1617e.g. make the output of commands like <code>git branch -a --contains
1618&lt;commit&gt;</code> needlessly verbose, as well as impacting anything else
1619that&#8217;ll work with the complete set of known references.</p></div>
1620<div class="paragraph"><p>These remote-tracking references can be deleted as a one-off with
1621either of:</p></div>

1623<div class="content">
1624<pre><code># While fetching
1625$ git fetch --prune &lt;name&gt;
1626
1627# Only prune, don't fetch
1628$ git remote prune &lt;name&gt;</code></pre>
1629</div></div>
1630<div class="paragraph"><p>To prune references as part of your normal workflow without needing to
1631remember to run that, set <code>fetch.prune</code> globally, or
1632<code>remote.&lt;name&gt;.prune</code> per-remote in the config. See
1633<a href="git-config.html">git-config(1)</a>.</p></div>
1634<div class="paragraph"><p>Here&#8217;s where things get tricky and more specific. The pruning feature
1635doesn&#8217;t actually care about branches, instead it&#8217;ll prune local &lt;&#8594;
1636remote-references as a function of the refspec of the remote (see
1637<code>&lt;refspec&gt;</code> and <a href="#CRTB">CONFIGURED REMOTE-TRACKING BRANCHES</a> above).</p></div>
1638<div class="paragraph"><p>Therefore if the refspec for the remote includes
1639e.g. <code>refs/tags/*:refs/tags/*</code>, or you manually run e.g. <code>git fetch
1640--prune &lt;name&gt; "refs/tags/*:refs/tags/*"</code> it won&#8217;t be stale remote
1641tracking branches that are deleted, but any local tag that doesn&#8217;t
1642exist on the remote.</p></div>
1643<div class="paragraph"><p>This might not be what you expect, i.e. you want to prune remote
1644<code>&lt;name&gt;</code>, but also explicitly fetch tags from it, so when you fetch
1645from it you delete all your local tags, most of which may not have
1646come from the <code>&lt;name&gt;</code> remote in the first place.</p></div>
1647<div class="paragraph"><p>So be careful when using this with a refspec like
1648<code>refs/tags/*:refs/tags/*</code>, or any other refspec which might map
1649references from multiple remotes to the same local namespace.</p></div>
1650<div class="paragraph"><p>Since keeping up-to-date with both branches and tags on the remote is
1651a common use-case the <code>--prune-tags</code> option can be supplied along with
1652<code>--prune</code> to prune local tags that don&#8217;t exist on the remote, and
1653force-update those tags that differ. Tag pruning can also be enabled
1654with <code>fetch.pruneTags</code> or <code>remote.&lt;name&gt;.pruneTags</code> in the config. See
1655<a href="git-config.html">git-config(1)</a>.</p></div>
1656<div class="paragraph"><p>The <code>--prune-tags</code> option is equivalent to having
1657<code>refs/tags/*:refs/tags/*</code> declared in the refspecs of the remote. This
1658can lead to some seemingly strange interactions:</p></div>
1659<div class="listingblock">
1660<div class="content">
1661<pre><code># These both fetch tags
1662$ git fetch --no-tags origin 'refs/tags/*:refs/tags/*'
1663$ git fetch --no-tags --prune-tags origin</code></pre>
1664</div></div>
1665<div class="paragraph"><p>The reason it doesn&#8217;t error out when provided without <code>--prune</code> or its
1666config versions is for flexibility of the configured versions, and to
1667maintain a 1=1 mapping between what the command line flags do, and
1668what the configuration versions do.</p></div>
1669<div class="paragraph"><p>It&#8217;s reasonable to e.g. configure <code>fetch.pruneTags=true</code> in
1670<code>~/.gitconfig</code> to have tags pruned whenever <code>git fetch --prune</code> is
1671run, without making every invocation of <code>git fetch</code> without <code>--prune</code>
1672an error.</p></div>
1673<div class="paragraph"><p>Pruning tags with <code>--prune-tags</code> also works when fetching a URL
1674instead of a named remote. These will all prune tags not found on
1675origin:</p></div>

1878The victim sends "have" lines advertising the IDs of objects it has that

1880 transfer if the peer also has them. The attacker chooses an object ID X

1882 X because the victim already has it. Now the victim believes that the
1883 attacker has X, and it sends the content of X back to the attacker
1884 later. (This attack is most straightforward for a client to perform on a
1885 server, by creating a ref to X in the namespace the client has access
1886 to and then fetching it. The most likely way for a server to perform it
1887 on a client is to "merge" X into a public branch and hope that the user
