Review request for kdelibs and David Faure.


Changes
-------

Use itemForUrl instead of a new QCache to store type information.


Description
-------

This patch, inspired by the issue reported in bug# 317676, attempts to cache and reuse the original result from the stat call in KDirListerCache::slotFileDirty. Since that stat call is only needed to determine whether the "dirty" resource is a file or directory, caching the result helps us avoid the potential for tons of KDE::stat calls. The stat will happen if you for example copy or download a large file into a local folder while that folder is being viewed in a file browsing app such as dolphin or konqueror. The cached information is removed if the resource being monitored is deleted or renamed.


This addresses bug 317676.

Thanks,
