<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"><p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The QML/JS language plugin contains a cache that stores information about known plugin paths, locations of imported files and binary QML modules. When the user imports a binary QML module, qmlplugindump is called in order to list its contents.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch slightly reworks how a lock is held and released in order to ensure that no lock is held while calling qmlplugindump. In some cases (bug 363509), it seems that qmlplugindump can hang or take a very long time to respond. If Cache is locked during that time, no other thread can parse any QML file. It may also be possible that other threads are blocked while the global DUChain lock is held, which may completely freeze parsing in any language.</p></pre>
