<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Moreover, I think that we might want to cache the contents of the .hidden file, to prevent that we read it, parse it and construct the QSet with the hidden files over and over again if a kioslave reports the UDSEntries in multiple batches.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Caching: it would have to include an mtime, to be able to detect changes. But indeed caching the last one read would be good, because while having a directory open, any change triggers an update job, which will re-read the .hidden file. Or while at it, could be a LRU cache, Qt makes it simple:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%">struct CacheHiddenFile {
QDateTime <span style="color: #008000">mtime</span>;
QSet<span style="color: #666666"><</span>QString<span style="color: #666666">></span> listedFiles;
}
QCache<span style="color: #666666"><</span>QString <span style="color: #408080; font-style: italic">/*dot hidden file*/</span>, CacheHiddenFile<span style="color: #666666">></span> m_cacheHiddenFiles;
m_cacheHiddenFiles.setMaxCost(<span style="color: #666666">10</span>);
</pre></div>
</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This requires making the filesInDotHiddenForDir method not file-static as I previously suggested, but rather a method of KCoreDirLister::Private, which would also have the above member.</p></pre>

For example, ".hidden" is not interpreted when I access a computer through SFTP in Nautilus. However, when I mount it externally using <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">sshfs</code>, it works.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Haven't checked Thunar.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">As for the caching, I'll try to take a look at it, but I'll probably need help (I have very little experience with KDE and Qt).</p></pre>

Dolphin was still using KDE4/Qt4 version of the library, so I only tested using the desktop folder widget, and "folder desktop".<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
It worked correctly when I pointed it to "~" and "~/Desktop" (I added ".hidden" there).<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
However, it didn't work when I pointed it to the "Desktop folder" (the default option, not the custom location "~/Desktop").<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
More testing is required.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The version for KDE4/Qt4 submitted to Bug #246260 was tested in Kubuntu 14.04, and it worked everywhere I tested (Dolphin, open/save dialogs, folder widget and detailed/tree view in Dolphin).<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
It wasn't an intensive test, though.</p></pre>
