<h2>Setting up a central repository<a class="headerlink" href="#setting-up-a-central-repository" title="Permalink to this headline">¶</a></h2>
<p>While the centralized workflow can be used by socially nominating
any branch on any computer as the central one, in practice most
teams have a dedicated server for hosting central branches.</p>
<p>Just as it’s best practice to use a shared repository locally,
it’s advisable to put central branches in a shared repository.
Note that central shared branches typically only want to
store history, not working copies of files, so their enclosing
repository is usually creating using the <tt class="docutils literal"><span class="pre">no-trees</span></tt> option, e.g.:</p>
<div class="highlight-python"><div class="highlight"><pre>bzr init-repo --no-trees bzr+ssh://centralhost/srv/bzr/PROJECT
</pre></div>
</div>
<p>You can think of this step as similar to setting up a new cvsroot or
Subversion repository. However, Bazaar gives you more flexibility
in how branches may be organised in your repository. See
<a class="reference external" href="shared_repository_layouts.html">Advanced shared repository layouts</a>
in the appendices for guidelines and examples.</p>

<div class="section" id="starting-a-central-branch">
<h2>Starting a central branch<a class="headerlink" href="#starting-a-central-branch" title="Permalink to this headline">¶</a></h2>
<p>There are two ways of populating a central branch with some initial
content:</p>
<blockquote>
<div><ol class="arabic simple">
<li>Making a local branch and pushing it to a central location</li>
<li>Making an empty central branch then committing content to it.</li>
</ol>
</div></blockquote>
<p>Here is an example of the first way:</p>
<div class="highlight-python"><div class="highlight"><pre>bzr init-repo PROJECT (prepare local repository)
bzr init PROJECT/trunk
cd PROJECT/trunk
(copy development files)
cp -ar ~/PROJECT . (copy files in using OS-specific tools)
bzr add (populate repository; start version control)
bzr commit -m "Initial import"
(publish to central repository)
bzr push bzr+ssh://centralhost/srv/bzr/PROJECT/trunk
</pre></div>
</div>
<p>Here is an example of the second way:</p>
<div class="highlight-python"><div class="highlight"><pre>bzr init-repo PROJECT (prepare local repository)
cd PROJECT
bzr init bzr+ssh://centralhost/srv/bzr/PROJECT/trunk
bzr checkout bzr+ssh://centralhost/srv/bzr/PROJECT/trunk
cd trunk
cp -ar ~/PROJECT . (copy files in using OS-specific tools)
bzr add (populate repository; start version control)
bzr commit -m "Initial import"
(publish to central repository)
</pre></div>
</div>
<p>Note that committing inside a working tree created using
the <tt class="docutils literal"><span class="pre">checkout</span></tt> command implicitly commits the content to
the central location as well as locally. Had we used the
<tt class="docutils literal"><span class="pre">branch</span></tt> command instead of <tt class="docutils literal"><span class="pre">checkout</span></tt> above, the
content would have only been committed locally.</p>
<p>Working trees that are tightly bound to a central location
like this are called <em>checkouts</em>. The rest of this chapter
explains their numerous features in more detail.</p>
