Git can expose each namespace as an independent repository to pull from and push to, while sharing the object store, and exposing all the refs to operations such as <a href="git-gc.html">git-gc(1)</a>.</p></div> <div class="paragraph"><p>Storing multiple repositories as namespaces of a single repository avoids storing duplicate copies of the same objects, such as when storing multiple branches of the same source. The alternates mechanism provides similar support for avoiding duplicates, but alternates do not prevent duplication between new objects added to the repositories without ongoing maintenance, while namespaces do.</p></div> <div class="paragraph"><p>To specify a namespace, set the <code>GIT_NAMESPACE</code> environment variable to the namespace. For each ref namespace, Git stores the corresponding refs in a directory under <code>refs/namespaces/</code>. For example, <code>GIT_NAMESPACE=foo</code> will store refs under <code>refs/namespaces/foo/</code>. You can also specify namespaces via the <code>--namespace</code> option to <a href="git.html">git(1)</a>.</p></div> <div class="paragraph"><p>Note that namespaces which include a <code>/</code> will expand to a hierarchy of namespaces; for example, <code>GIT_NAMESPACE=foo/bar</code> will store refs under <code>refs/namespaces/foo/refs/namespaces/bar/</code>. This makes paths in <code>GIT_NAMESPACE</code> behave hierarchically, so that cloning with <code>GIT_NAMESPACE=foo/bar</code> produces the same result as cloning with <code>GIT_NAMESPACE=foo</code> and cloning from that repo with <code>GIT_NAMESPACE=bar</code>. It also avoids ambiguity with strange namespace paths such as <code>foo/refs/heads/</code>, which could otherwise generate directory/file conflicts within the <code>refs</code> directory.</p></div> <div class="paragraph"><p><a href="git-upload-pack.html">git-upload-pack(1)</a> and <a href="git-receive-pack.html">git-receive-pack(1)</a> rewrite the names of refs as specified by <code>GIT_NAMESPACE</code>. git-upload-pack and git-receive-pack will ignore all references outside the specified namespace.</p></div> <div class="paragraph"><p>The smart HTTP server, <a href="git-http-backend.html">git-http-backend(1)</a>, will pass GIT_NAMESPACE through to the backend programs; see <a href="git-http-backend.html">git-http-backend(1)</a> for sample configuration to expose repository namespaces as repositories.</p></div> <div class="paragraph"><p>For a simple local test, you can use <a href="git-remote-ext.html">git-remote-ext(1)</a>:</p></div> <div class="listingblock"> <div class="content"> <pre><code>git clone ext::'git --namespace=foo %s /tmp/prefixed.git'</code></pre> </div></div> </div> </div> <div class="sect1"> <h2 id="_security">SECURITY</h2> <div class="sectionbody"> <div class="paragraph"><p>Anyone with access to any namespace within a repository can potentially access objects from any other namespace stored in the same repository. You can’t directly say "give me object ABCD" if you don’t have a ref to it, but you can do some other sneaky things like:</p></div> <div class="olist arabic"><ol class="arabic"> <li> <p> Claiming to push ABCD, at which point the server will optimize out the need for you to actually send it. Now you have a ref to ABCD and can fetch it (claiming not to have it, of course). </p> </li> <li> <p> Requesting other refs, claiming that you have ABCD, at which point the server may generate deltas against ABCD. </p> </li> </ol></div> <div class="paragraph"><p>None of this causes a problem if you only host public repositories, or if everyone who may read one namespace may also read everything in every other namespace (for instance, if everyone in an organization has read permission to every repository).</p></div> </div> </div> </div> <div id="footnotes"><hr /></div> <div id="footer"> <div id="footer-text"> Last updated 2013-06-10 20:01:55 UTC </div> </div> </body> </html>
