    <p>I've written a fairly simply QuickLook plugin, which displays the files of a <code>.torrent</code> file,</p> <p>The complete code is <a href="http://github.com/dbr/qltorrent/tree/45c4f1cb8a2d1e101a7543ebedc78fc1c8b87c01" rel="nofollow noreferrer">here on Github</a>, and the main file is <a href="http://github.com/dbr/qltorrent/blob/45c4f1cb8a2d1e101a7543ebedc78fc1c8b87c01/torrent.m" rel="nofollow noreferrer"><code>torrent.m</code></a></p> <p>The reason I'm looking for feedback is it's acting slightly weirdly.. After building/installing the plugin (into <code>~/Library/QuickLook/</code>), and running..</p> <pre><code>qlmanage -r; qlmanage -p ~/test.torrent </code></pre> <p>..it works perfectly, but actually invoking QuickLook (via the "space" or <code>cmd+y</code> shortcut), the first time is fine, then there are problems - strange characters after the data (similar to the solved <a href="https://stackoverflow.com/questions/550405/convert-nsdata-bytes-to-nsstring">with this question</a>), or it falls back to the default "show file info and icon" quicklook plugin.</p> <p>I'm assuming it's a memory-leak related problem.. I could be wrong, but the qlmanage command's memory should be "clean" (being a new process), but the quicklook daemon is long running, meaning it would be messed up by the leak..</p> <p>I ran the <a href="https://stackoverflow.com/questions/172125/avoiding-finding-and-removing-memory-leaks-in-cocoa/172243#172243">Clang static analyser</a> on the code, and the only leaks it found were in the <a href="http://github.com/dbr/qltorrent/blob/master/BEncoding.m" rel="nofollow noreferrer"><code>BEncoding.m</code></a>.. I found it hard to believe the library was at fault (not my messy code), espically given <a href="https://stackoverflow.com/questions/364172/memory-leaks-in-newly-created-cocoa-app-when-using-garbage-collection/364994#364994">this answer</a> saying the <code>leak</code> tool is innacurate with garbage-collected code (not sure if this applies to Clang?), thus this question!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
