plugin. This happens because there is a race condition between<br />
<tt style="background: #ebebeb; font-size: 13px;">LoadJob::onFinished()</tt> (where we read some <tt style="background: #ebebeb; font-size: 13px;">LoadJob</tt> members) and<br />
<tt style="background: #ebebeb; font-size: 13px;">LoadJob::onNewEntry()</tt> (where we write those members).</p>
<p><tt style="background: #ebebeb; font-size: 13px;">onFinished()</tt> is called when <tt style="background: #ebebeb; font-size: 13px;">list()</tt> returns, in <tt style="background: #ebebeb; font-size: 13px;">LoadJob::doWork()</tt>.<br />
But that might happen before <tt style="background: #ebebeb; font-size: 13px;">onNewEntry()</tt> is called, since they are executed<br />
in two different threads.</p>
<p>This patch puts the <tt style="background: #ebebeb; font-size: 13px;">onFinished()</tt> call in the event queue, just like the<br />
single-thread case does (where we emit the <tt style="background: #ebebeb; font-size: 13px;">finished</tt> signal from<br />
<tt style="background: #ebebeb; font-size: 13px;">CliInterface</tt>).</p>
<p>An alternative could be using a <tt style="background: #ebebeb; font-size: 13px;">DirectConnection</tt> for the <tt style="background: #ebebeb; font-size: 13px;">entry</tt> signal, but<br />
that is more invasive/ugly.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Run <tt style="background: #ebebeb; font-size: 13px;">extracttest</tt> a bunch of times, with/without the patch. It should randomly<br />
fail without the patch, it should always pass with the patch.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rARK Ark</div></div></div><br /><div><strong>BRANCH</strong><div><div>fix-extracttest</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D3111" rel="noreferrer">https://phabricator.kde.org/D3111</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>kerfuffle/jobs.cpp</div></div></div><br /><div><strong>EMAIL PREFERENCES</strong><div><a href="https://phabricator.kde.org/settings/panel/emailpreferences/" rel="noreferrer">https://phabricator.kde.org/settings/panel/emailpreferences/</a></div></div><br /><div><strong>To: </strong>elvisangelaccio, rthomsen<br /><strong>Cc: </strong>kde-utils-devel, tctara<br /></div>
