Bug 447965

well, in some quick-n-dirty testing, it appears kde3 and kde4 can share the 
*_datadir/kdeui, so that's what I'll try.  omit /usr/share/apps/kdeui from 
kdelibs3 and include a compat symlink in kdelibs-common.

doesn't solve the bigger kde4-config --path data problem, however.

excert from from #kde-devel: 
[08:36] <thiago> rdieter: KStandardDirs::addKDEDefaults
[08:36] <thiago> rdieter: it's a matter of swapping a few lines

doesn't seem that easy to me. :)

Argh, not again!
Rex, you CANNOT change a directory to a symlink! RPM doesn't support it.

I untagged the offending builds from dist-f10. (Kinda surprised that Koji let 
me do that given that those weren't my builds, but whatever.)

Rex cleaned up the hack meanwhile so it builds.

But there's now a non-hack fix (i.e. a fix for the underlying problem with the 
search path) here (thanks to Sune Vuorela (pusling) from Debian):
http://lists.kde.org/?l=kde-core-devel&m=121209523714815&w=2

That fix would also fix bug 446575 so in theory we could reintroduce those 
KCMs.

Rex, could you please revert the hack? the above fix looks good to me, we can 
add it in our package

Than, careful, I discussed some details with pusling on IRC, notably the 
priorities will be wrong for the config files. I'll come up with a patch which 
does the right thing for config files too ASAP.

Re: comment #6
There is merit to leaving it as-is:
1 .kde3 and kde4 apps now share kdeui (as intended), so about->kde dialogs look
consistent
2. it's saves ~300k

Patches here:
4.0: http://repo.calcforge.org/f9/kdelibs-4.0.4-kstandarddirs.patch
4.1: http://repo.calcforge.org/f9/kdelibs-4.0.80-kstandarddirs.patch

These replace the existing kdelibs-4.0.4-kstandarddirs.patch, I added 
the /etc/kde hack to this patch. The difference between the combination of the 
existing patch and pusling's and the above version is that I fixed the search 
order for config files so /etc/kde and the kde-settings profile come first (so 
the desired preference order: sysadmin customizations before Fedora defaults 
before upstream defaults is maintained).

Kevin, the patch looks good, i will summit the fix into CVS and build it

Testing kdelibs-4.0.4-11.fc9
$ kde4-config --path data
~/.kde/share/apps:/usr/share/kde4/apps:/usr/share/kde-settings/kde-profile/default/share/apps:/usr/share/apps

Not sure if that's exactly what we want, but maybe it's good enough.

You want /usr/share/kde-settings/kde-profile/default/share/apps to come first? 
That'll be a bit hard to implement, I'm afraid. :-(

Config is special-cased so you get the right thing (kde-profile first), but if 
I did the same thing for apps which I do for config, /usr/share/kde4/apps would 
be last and we'd lose again.

We don't currently put anything there anyway, so it's no big deal.

I think we've got this one nailed

Yes, that has been fixed for ages. The search path is now:
~/.kde/share/apps/:/usr/share/kde-settings/kde-profile/default/share/apps/:/usr/share/kde4/apps/
The KDE 3 /usr/share/apps/ is not searched by KDE 4 anymore at all.

For the record, this was fixed in kdelibs-4.0.80-2.fc10, all the 4.1 and 4.2 updates for F9 have this fixed, as does the F10 release.
