Description Hans-J. Ullrich 2009-05-29 19:18:39 UTC 
Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Dear maintainers,

as many older KDE-applications and addons are still needing kdelibs4c2a out of KDE-3.5.XX in KDE-4.XX, many services are started twice (or double). 

This is causing some problems (it is making the system slow, and it causes the load of lots of unecessary processes).

Please let me explain: For example, there are 2 processes started (kded and kded4) which do the same. The old one is started through kdelibs4c2a , the other one through kdelibs5. This IMO is not necessary, isn't it?

The same is with the process kdeinit and kdeinit4, both do the same, but loading both needs unnecessary cpu power.


The third thing, I discovered, is that a lot of processes (20 and more) named kio-httpd are started (each uses 4M of RAM), which seem caused of the described problem above.

So, as there are still lots of applications (amarok is one of them, kpowersave, and lots more) which still need kdelibs4c2a, it is a big problem, to change them all. Otherwise, users should not be forced to remove them, just because they want to use KDE-4!

So, my idea is, to merge kdelibs5 and kdelibs4c2a, so you get ONE library for all, or , the other option might be, to eliminate all functions out of kdelibs4c2a, which are already done by kdelibs5.

If this is already fixed in KDE-4.3, forget about this bugreport.

Thanks for reading anyway!


Best regards

This is necessary, as KDE 3 and KDE 4 services are totally independent, and they general cannot interact anyway (different incompatible libraries, different inter-process communication system, etc).

kdeinit and kdeinit4 stay idle if there's no work for them.

Unrelated.

I don't agree this is an big problem, or even some problem.

This cannot be done, as (as said above) KDE 3 libraries and KDE 4 ones are totally independent. You cannot make KDE 3 applications use KDE 4 libraries, and vice versa, this is impossible to do.

The bottom line is: we designed to make KDE 3 applications runnable in a KDE 4 desktop and vice versa, so services for both _are_ needed.
More and more applications are getting ported to KDE 4, so over time you'll have gradually less running KDE 3 applications.
