Amarok 1.4.8, mysql, and 8 to 10 s hangs every track change or rating

Thu Jan 31 12:14:56 UTC 2008

Hi,

Moodbar is disabled, so it can't be the "hanging" source.

It definitely is a database query pb, happening when the context view is
redraw (when the method showArtistsAlbums() is called). I've noticied that
this method is also invoked when the collection vertical tab is selected,
and when I change track or rate a song, But, if i had previously selected
the wikipedia on context view, and then switch to collection tab, and then
play next track, everything goes straight on, no waiting time ... (and in
the debug output, showArtistsAlbums() isn't called at all)
I think somehow, the method is called even if it's not needed. Maybe it will
be better, if it's only called when needed but don't know where to find this
on the source code !

Well best thing to do : wait for Amarok 2 :o)
Thanks
