<h2>27.1. Error in manifest is not considered an error by cdist<a class="headerlink" href="#error-in-manifest-is-not-considered-an-error-by-cdist" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<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"><div class="highlight"><pre><span></span>% cat ~/.cdist/manifest/init
|
||
|
|
<span class="s2">"</span><span class="nv">$__manifest</span><span class="s2">/special"</span>
|
||
|
|
% cat ~/.cdist/manifest/special
|
||
|
|
<span class="c1">#!/bin/sh</span>
|
||
|
|
<span class="nb">echo</span> <span class="s2">"Here is an unclean exiting script"</span>
|
||
|
|
somecommandthatdoesnotexist
|
||
|
|
<span class="nb">echo</span> <span class="s2">"I continue here although previous command failed"</span>
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<p>We can clearly see that <strong>somecommandthatdoesnotexist</strong>
|
||
|
|
will fail in ~/.cdist/manifest/special. But as the custom
|
||
|
|
script is not called with the -e flag (exit on failure) of shell,
|
||
|
|
it does not lead to an error. And thus cdist sees the exit 0
|
||
|
|
code of the last echo line instead of the failing command.</p>
|
||
|
|
<p>All scripts executed by cdist carry the -e flag.
|
||
|
|
To prevent the above from happening, there are three solutions available,
|
||
|
|
two of which can be used in the calling script:</p>
|
||
|
|
<div class="highlight-sh"><div class="highlight"><pre><span></span><span class="c1"># Execute as before, but abort on failure</span>
|
||
|
|
sh -e <span class="s2">"</span><span class="nv">$__manifest</span><span class="s2">/special"</span>
|
||
|
|
|
||
|
|
<span class="c1"># Source the script in our namespace, runs in a set -e environment:</span>
|
||
|
|
. <span class="s2">"</span><span class="nv">$__manifest</span><span class="s2">/special"</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"><div class="highlight"><pre><span></span>% cat ~/.cdist/manifest/special
|
||
|
|
<span class="c1">#!/bin/sh -e</span>
|
||
|
|
...
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
