[gentoo-dev] [RFC] XDG_DATA_DIRS in /etc/env.d

[gentoo-dev] [RFC] XDG_DATA_DIRS in /etc/env.d

[Doug Goldstein]

Howdy all,

Diego (Flameeyes) brings about a good point from bug #95867 [1]. An 
issue that's actually affected me at work with something I'm working on, 
so I was the perfect person to ask to press this forward.


Basically XDG_DATA_DIRS is where FreeDesktop has standardized the 
location of icons, desktop entries, directory entries and other misc 
data. In Gentoo we've hard coded it to 
XDG_DATA_DIRS=/usr/share:/usr/kde/3.5/share however it's always 
sub-optimal to hardcode different settings.

Diego (sorry, don't have anything but English keys) has proposed is 
creating the ability for XDG_DATA_DIRS to be set via /etc/env.d entries 
which sounds like the best plan. He's willing to make the change and I'm 
all for it. Basically this is a request for comments on the idea. Anyone 
opposed? If not then the change will happen 3 days from this e-mail.

Here's a summary of what Diego sent me:

Basically, it's a matter of defining XDG_DATA_DIRS to 
/usr/share:/usr/kde/3.5/share for the users, not difficult, but I think 
what happens if a package in /opt wants to have its share directory 
there too (would be proper, rather than polluting /usr/share space).
The quick solution is to set XDG_DATA_DIRS in COLON_SEPARATED, in every 
env.d file that defines XDG_DATA_DIRS to be safe. I can do it, but it 
needs to be announced first at least.

I'm all for that.
See also bug about KDE applications not showing up in GNOME menus
https://bugs.gentoo.org/show_bug.cgi?id=139697
This would probably get solved then as well, as /usr/kde/3.5/share would
be included in XDG_DATA_DIRS in Gnome sessions as well. Currently there
is no XDG_DATA_DIRS set at all in a Gnome session, so just the
default /usr/share is looked at, and setting it in startup scripts
sounds just wrong.
I'm not sure how you'd approach this when multiple kde versions are
present (like /usr/kde/3.4 AND /usr/kde/3.5 in the past), in what order
they'd be there, how you ensure said order and so on. In Gnome land
there is no such SLOTting.

This gives me some bad memories with certain spyware. And I don't get
what you americans find in American Football. Go-go soccer! (football
really, but I can't say that when americans are reading :(  )
How's that for stirring up the pot? :p
