Schedules/KDE4/4.0 Release Beta Goals

This page will list all the release goals for the beta cycle of KDE4. It will contain not only the goals, but also the current state and what YOU can do to help out.

You can not add new items to this list. Only maintainers should edit their own section. If you wish to add new items, send a mail to [email protected]

Plasma

• current state: showstopper
• contact: aseigo
• goal:
• howto help:
• expected time of arrival:

Color configuration

• current state: no showstopper anymore
• contact: Matthew Woehlke
• goal: one needs to be able to change the palette.
• howto help: Honestly, as of a few days ago I think we are there. It needs a lot of polish but at this point I think something would have to go horribly wrong for us to not have a functional kcm for 4.0. (Whether or not it will be beautiful I don't know, but functional it mostly is right now. The effects are not hooked up but I don't think that is a showstopper since it is new to 4.0.)
• expected time of arrival: two weeks to two months I would guess to polish and implement the last missing bits.

Oxygen style

• current state: showstopper
• contact: mwoehlke, boemann, #oxygen

Konqueror

• current state: showstopper
• contact: David Faure
• goal: Konqueror must be able to browse the web and to be used as a file manager again, I'm mostly aiming for "no regressions compared to KDE3"
• howto help:
  • Help is most welcome. [email protected] is the place for discussion of both aspects of konqueror development. Web browsing seems in better shape than filemanagement right now, so small tasks are fixing regressions in the webbrowsing-related code in konqueror and its dependencies. For instance there is finally a patch now about fixing the non-working Return key in the location bar URL; I'm sure there's more like that.
  • Bigger tasks include:
    • defining a future for the sidebar code -- volunteer(s) needed!
    • finishing the integration of the dolphin part for file management. For instance, we need actions for switching between view modes...
    • Porting all KFileItemList-based API in kdelibs to QList<KFileItem>, especially KPropertiesDialog. Easy but might involve much porting in the other modules, and must be done before the final API freeze (beginning of october?).
• expected time of arrival: 2010? ;-)))

Dolphin

• current state: no showstopper anymore
• contact: Peter Penz
• goal: I think Dolphin is in a quite acceptable state now and I'll have a lot of time during the next week to fix the most serious bugs. David Faure and Rafael Fernández López also investigate a lot of time in Dolphin related things so I'm optimistic that Dolphin should be in a good shape for KDE 4.0.
• howto help:
  • I'm concerned a little bit whether the Dolphin KPart is matured enough for getting Konqueror in shape. Maybe David can comment whether some help is needed in this area (I've set David to CC).
    • I'm not sure about the state of Nepomuk. Currently the performance is too slow for sorting items by tags or rating. It would be possible to use an internal cache in Dolphin for this, but this would only reduce the time from O(n*log(n)) to O(n) and the problem is n: reading e. g. 30 items takes several seconds... Maybe Sebastian Trüg could need some support. In the worst case I'd suggest to remove the "sort by tags" and "sort by rating" feature in Dolphin for KDE 4.0.
• expected time of arrival: My plan is that all serious bugs get closed until the end of September. No known showstoppers are left :-)

Printing

• current state: showstopper
• contact: Alex Merry
• goal: Printing support working in all applications that can currently print, with print preview and customisable dialogs
• help needed: We need to actually decide the precise API we are going to use, but then every application needs porting to it. In particular, the people currently working on it either have very little time, are not really programmers or have very little experience in dealing with printing systems. And no-one who has experience of printing systems can agree what the best way forward is.
• howto help: send e-mail to the [email protected] mailing list
• expected time of arrival: Once we have a decision on the API and have implemented it, the porting could probably be done in a few days.

Sound

• current state: showstopper
• contact: Matthias Kretz
• goal:
  1. sane defaults implemented (audio device selection, mixing)
  2. fix KIO playback: currently I'm seeing inexplicable memory corruption
  3. usable KMix
  4. Playing short sound files sometimes only plays the start of the sound (which can be almost nothing). This is a showstopper for notification sounds. Some reported that this is a bug in xine-lib, but I have not looked into the issue.
• howto help: I certainly want help. But I don't know how I could label any of the tasks as small because for most things you need quite a good overview... :-( Mailinglists: [email protected] or [email protected], IRC: #phonon ping Vir
  • Local audio playback is working quite OK, but there are some issues that are still open:
    • https://bugzilla.redhat.com/show_bug.cgi?id=284171
    • Sound hardware/ALSA setup
      • Currently the default list of audio devices to use is in arbitrary order. This needs to be fixed otherwise esd, artsd, jack or S/PDIF output can turn up as most preferred device and make it look like nothing is working. This might need something along the lines of a "hardware database".
      • There's a report that outputting to a dmix: ALSA device using a hardware mixing capable soundcard made mixing not work at all (don't ask me why), so the ALSA device name choosing algorithm might need to become a bit smarter. I think the safest bet for now is to use the default:CARD=... device string, but with that you can only choose what card you want, not what device on that card (I don't have hardware where this would make a difference, so no idea if it's needed).
      • Even though defaults.pcm.ipc_gid is set to audio and defaults.pcm.ipc_perm is set to 0660, dmix does not work for more than one user at the same time (both users are in the audio group). A workaround is to set ipc_perm to 0666, but a real fix would be nicer.
    • kmix is not in a good state (yet). E.g. it crashes on application shutdown for me (and with that forgetting all changes done in the config dialog). It still does not react on plugged/unplugged soundcard or new/removed software control.
    • Playing short sound files sometimes only plays the start of the sound (which can be almost nothing). This is a big problem for notifications. Some reported that this is a bug in xine-lib, but I have not looked into the issue.
    • xine-lib behaves bad wrt. memory allocations. run e.g. mediaobjecttest in valgrind --tool=massif
• expected time of arrival: 1. should be doable in a week or so. For 2. and 4. I have no idea because I don't know the cause and my gdb is busted. :'( 3. is a bit out of my scope, though I might come up with a test app that does what I want soon...
