<p>Situation: You are executing other scripts from a manifest.
This script fails, but cdist does not recognise the error.
An example script would be something like this:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>% cat ~/.cdist/manifest/init
<span class="s2">&quot;</span><span class="nv">$__manifest</span><span class="s2">/special&quot;</span>
% cat ~/.cdist/manifest/special
<span class="c1">#!/bin/sh</span>
<span class="nb">echo</span> <span class="s2">&quot;Here is an unclean exiting script&quot;</span>
somecommandthatdoesnotexist
<span class="nb">echo</span> <span class="s2">&quot;I continue here although previous command failed&quot;</span>
</pre></div>
</div>
<p>We can clearly see that <strong>somecommandthatdoesnotexist</strong>
will fail in ~/.cdist/manifest/special. But as the custom
script is not called with the -e flag (exit on failure) of shell,
it does not lead to an error. And thus cdist sees the exit 0
code of the last echo line instead of the failing command.</p>
<p>All scripts executed by cdist carry the -e flag.
To prevent the above from happening, there are three solutions available,
two of which can be used in the calling script:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="c1"># Execute as before, but abort on failure</span>
sh -e <span class="s2">&quot;</span><span class="nv">$__manifest</span><span class="s2">/special&quot;</span>
<span class="c1"># Source the script in our namespace, runs in a set -e environment:</span>
. <span class="s2">&quot;</span><span class="nv">$__manifest</span><span class="s2">/special&quot;</span>
</pre></div>
</div>
<p>The third solution is to include a shebang header in every script
you write to use the -e flag:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>% cat ~/.cdist/manifest/special
<span class="c1">#!/bin/sh -e</span>
...
</pre></div>
</div>

<h2><span class="section-number">31.2. </span>Using debug dump helper script<a class="headerlink" href="#using-debug-dump-helper-script" title="Permalink to this headline"></a></h2>
<p>Since cdist stores data to local cache that can be used for debugging there
is a helper script that dumps data from local cache,
<a class="reference external" href="man1/cdist-dump.html">cdist-dump</a>.</p>
<p>For more info see:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>cdist-dump -h
</pre></div>
</div>
<p>Or from cdist git cloned directory:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>./scripts/cdist-dump -h
</pre></div>
