<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hi, thanks for your work!
First, I must acknowledge that our current file playlist code is a big mess and it certainly needs cleanup and code deduplication, your work is therefore greatly appreciated. I have reviewed just one file when it came to my mind: instead of introducing LazyPlaylistFile, the lazy-loading logic should be incorporated directly to PlaylistFile! There's no reason to have playlist files without lazy loading.
Could you please rework the patch eliminating LazyPlaylistFile? Also please pay attention to code style (e.g. spaces around parameters etc.) and to document methods along the way. (you seem to add methods to PlaylistFile. Please keep the public interface minimal usable - the setName() / setFilename() / setUrl() looks really scary - what does what? Does the file get renamed?) I understand this is mainly existing mess, not your new code. :-|</pre>

<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;">I've started my changes with an implementation of a ASXPlaylist class,
due this work I've found that implementation of different playlist file
types has different logic, as result I end up with a rewriting
playlist's implementations.
As example of difference:
-- Constructor M3UPlaylist::M3UPlaylist( const KUrl &url ) sets a url, but
does not load playlist, therefore loading of playlist are
posponed till data from playlist are actualy needed (lazy loading)
On the other hand constructor XSPFPlaylist::XSPFPlaylist( const
KUrl &url, bool autoAppend ) loads playlist.
The main idea of proposed changes is to create a unify code for
processing playlist files:
-- lazy loading through LazyLoadPlaylist
-- common functionality was moved to PlaylistFile.
It is worth to be noticed that this patch changes structure of
playlist's classes, bit does not changes their behavior, even if this behavior
is inconsistent in some cases.
In following patch-requests I plan to submit ASX Playlist parser and
organize playlists processing in more consistent way.</pre>

2) For all playlists I've also checked loading and
