<div class="section" id="welcome">
<h2>20.1. Welcome<a class="headerlink" href="#welcome" title="Permalink to this headline"></a></h2>
<p>Welcome dear hacker! I invite you to a tour of pointers to
get into the usable configuration mangament system, cdist.</p>
<p>The first thing to know is probably that cdist is brought to
you by people who care about how code looks like and who think
twice before merging or implementing a feature: Less features
with good usability are far better than the opposite.</p>
</div>
<div class="section" id="reporting-bugs">
<h2>20.2. Reporting bugs<a class="headerlink" href="#reporting-bugs" title="Permalink to this headline"></a></h2>
<p>If you believe you&#8217;ve found a bug and verified that it is
in the latest version, drop a mail to the cdist mailing list,
subject prefixed with &#8220;[BUG] &#8221; or create an issue on github.</p>
</div>
<div class="section" id="coding-conventions-everywhere">
<h2>20.3. Coding conventions (everywhere)<a class="headerlink" href="#coding-conventions-everywhere" title="Permalink to this headline"></a></h2>
<p>If something should be better done or needs to fixed, add the word FIXME
nearby, so grepping for FIXME gives all positions that need to be fixed.</p>
<p>Indention is 4 spaces (welcome to the python world).</p>
</div>
<div class="section" id="how-to-submit-stuff-for-inclusion-into-upstream-cdist">
<h2>20.4. How to submit stuff for inclusion into upstream cdist<a class="headerlink" href="#how-to-submit-stuff-for-inclusion-into-upstream-cdist" title="Permalink to this headline"></a></h2>
<p>If you did some cool changes to cdist, which you value as a benefit for
everybody using cdist, you&#8217;re welcome to propose inclusion into upstream.</p>
<p>There are though some requirements to ensure your changes don&#8217;t break others
work nor kill the authors brain:</p>
<ul>
<li><p class="first">All files should contain the usual header (Author, Copying, etc.)</p>
</li>
<li><p class="first">Code submission must be done via git</p>
</li>
<li><p class="first">Do not add cdist/conf/manifest/init - This file should only be touched in your
private branch!</p>
</li>
<li><p class="first">Code to be included should be branched of the upstream &#8220;master&#8221; branch</p>
<blockquote>
<div><ul class="simple">
<li>Exception: Bugfixes to a version branch</li>
</ul>
</div></blockquote>
</li>
<li><p class="first">On a merge request, always name the branch I should pull from</p>
</li>
<li><p class="first">Always ensure <strong>all</strong> manpages build. Use <strong>./build man</strong> to test.</p>
</li>
<li><p class="first">If you developed more than <strong>one</strong> feature, consider submitting them in
separate branches. This way one feature can already be included, even if
the other needs to be improved.</p>
</li>
</ul>
<p>As soon as your work meets these requirements, write a mail
for inclusion to the mailinglist <strong>cdist at cdist &#8211; at &#8211; l.schottelius.org</strong>
or open a pull request at <a class="reference external" href="http://github.com/telmich/cdist">http://github.com/telmich/cdist</a>.</p>
</div>
<div class="section" id="how-to-submit-a-new-type">
<h2>20.5. How to submit a new type<a class="headerlink" href="#how-to-submit-a-new-type" title="Permalink to this headline"></a></h2>
<p>For detailled information about types, see <a class="reference external" href="cdist-type.html">cdist type</a>.</p>
<p>Submitting a type works as described above, with the additional requirement
that a corresponding manpage named man.text in asciidoc format with
the manpage-name &#8220;cdist-type__NAME&#8221; is included in the type directory
AND asciidoc is able to compile it (i.e. do NOT have to many &#8220;=&#8221; in the second
line).</p>
<p>Warning: Submitting &#8220;exec&#8221; or &#8220;run&#8221; types that simply echo their parameter in
<strong>gencode</strong> will not be accepted, because they are of no use. Every type can output
code and thus such a type introduces redundant functionality that is given by
core cdist already.</p>

<div class="section" id="example-git-workflow">
<h2>20.6. Example git workflow<a class="headerlink" href="#example-git-workflow" title="Permalink to this headline"></a></h2>
<p>The following workflow works fine for most developers</p>
<div class="highlight-sh"><div class="highlight"><pre><span></span><span class="c1"># get latest upstream master branch</span>
git clone https://github.com/telmich/cdist.git
<span class="c1"># update if already existing</span>
<span class="nb">cd</span> cdist<span class="p">;</span> git fetch -v<span class="p">;</span> git merge origin/master
<span class="c1"># create a new branch for your feature/bugfix</span>
<span class="nb">cd</span> cdist <span class="c1"># if you haven&#39;t done before</span>
git checkout -b documentation_cleanup
<span class="c1"># *hack*</span>
*hack*
<span class="c1"># clone the cdist repository on github if you haven&#39;t done so</span>
<span class="c1"># configure your repo to know about your clone (only once)</span>
git remote add github git@github.com:YOURUSERNAME/cdist.git
<span class="c1"># push the new branch to github</span>
git push github documentation_cleanup
<span class="c1"># (or everything)</span>
git push --mirror github
<span class="c1"># create a pull request at github (use a browser)</span>
<span class="c1"># *fixthingsbecausequalityassurancefoundissuesinourpatch*</span>
*hack*
<span class="c1"># push code to github again</span>
git push ... <span class="c1"># like above</span>
<span class="c1"># add comment that everything should be green now (use a browser)</span>
<span class="c1"># go back to master branch</span>
git checkout master
<span class="c1"># update master branch that includes your changes now</span>
git fetch -v origin
git diff master..origin/master
git merge origin/master
</pre></div>
</div>
<p>If at any point you want to go back to the original master branch, you can
use <strong>git stash</strong> to stash your changes away:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="o">..</span> <span class="n">code</span><span class="o">-</span><span class="n">block</span><span class="p">::</span> <span class="n">sh</span>
</pre></div>
</div>
<blockquote>
<div><p># assume you are on documentation_cleanup
git stash</p>
<p># change to master and update to most recent upstream version
git checkout master
git fetch -v origin
git merge origin/master</p>
</div></blockquote>
<p>Similar when you want to develop another new feature, you go back
to the master branch and create another branch based on it:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="o">..</span> <span class="n">code</span><span class="o">-</span><span class="n">block</span><span class="p">::</span> <span class="n">sh</span>
</pre></div>
</div>
<blockquote>
<div><p># change to master and update to most recent upstream version
git checkout master
git fetch -v origin
git merge origin/master</p>
<p>git checkout -b another_feature</p>
</div></blockquote>
<p>(you can repeat the code above for as many features as you want to develop
in parallel)</p>
</div>
