<h2>27.1. Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>Since version 4.8.0 cdist, by default, saves output streams to local cache.
Saving output streams is implemented because important information was lost
during a config run, hidden in all other output.
Now all created output is bound to the context where it was produced.</p>
<p>Saving output streams include stdout and stderr of init manifest, remote
commands and for each object stdout and stderr of manifest, gencode-* and code-*.
Output stream files are created only if some output is produced. For more info
on these cache files see <a class="reference external" href="cdist-cache.html">Local cache overview</a>.</p>
<p>Also, in case of an error, cdist can now exit and show all information it has
about the error.</p>
<p>For example:</p>

<p>Upon successful run execution state is saved to local cache and temporary
directory is removed.
In case of an error temporary directory is not removed and can be further
discovered.</p>
<p>There is also an option <strong>-S/--disable-saving-output-streams</strong> for
disabling saving output streams. In this case error reporting can look
like this:</p>
