[gentoo-dev] Removal of kdeprefix news item

[-- Attachment #1.1: Type: text/plain, Size: 396 bytes --]

After a few years of masking, we will finally remove support for USE=kdeprefix 
from all KDE ebuilds/eclasses on or about 2011-06-06, moving everyone to the 
recommended FHS layout.  The attached news item meant to serve as an early 
warning to affected users.

I plan to commit this news item on 2011-05-22 to give about 2 weeks warning to 
users.

Please comment and review.

Title: Removal of kdeprefix support
Author: Jonathan Callen <abcd@gentoo.org>
Content-Type: text/plain
Posted: 2011-05-22
Revision: 1
News-Item-Format: 1.0
Display-If-Installed: kde-base/kdelibs[kdeprefix]

On 2011-06-06, kdeprefix support will be removed from all KDE ebuilds in
portage.  After this is done, only one version of KDE SC will be able to
be installed at a time on a system.  If you are currently using
USE=kdeprefix to install multiple versions of KDE SC simultaneously, you
will need to migrate to a non-kdeprefix installation.

To migrate, you will need to set USE=-kdeprefix (or remove the manual
unmasking of that flag in /etc/portage/profile) and rebuild all of the
installed packages in kde-base/.  To reinstall these packages, you can
run: emerge --oneshot $(qlist -IC kde-base/)

I don't think that USE dependencies (or any other EAPI specific
features) are allowed here.

Is it guaranteed that your users have portage-utils installed?
Otherwise the qlist command may not be available.

You should file a bug about that; I'm sure one of the portage guys can
change the crap code I wrote 4 years ago to use the normal dependency
checking code for installed atoms.

But we wouldn't know if users have the updated portage version
installed, so it doesn't help for the current news item.

I think for a proper solution we would have to increase the number of
the News-Item-Format. Maybe even add a new header field for the EAPI.

Could just use an 'eapi' file in the news directory. Although does
Portage support that?

This seems like the absolute easiest solution to use going forward.

Having an 'eapi' file present seems workable as well, though I'm not
certain which is the easiest for Portage to implement today.

Are there any other suggestions, or does anyone disagree with Ulrich's
suggestion?

The GLEP does not make any meantion as to whether it is legal to use 
USE dependencies here.  I have, however, tested with portage and 
portage itself Does The Right Thing when faced with a USE dep in 
Display-If-Installed.

I had thought that we depended on this, but I was mistaken (the 
dependency was pulled in via pambase).  I guess we could just use 
`emerge --update --deep --newuse @world` (and yes, @world is available 
in stable portage).

test -x /usr/bin/qlist && emerge --oneshot $(qlist -IC kde-base/) \
|| emerge --update --deep --newuse @world

?

reading the code for the version of portage I have installed:

The NewsManager will call Isvalid on each news item and each news item
will scan its restrictions for 'valid-ness' and report that upward. So
if we are lucky, on old versions of portage, portage.isvalidatom will
report the USE-dep as an invalid atom and portage will print mean
errors messages about 'invalid news items' but will not throw up (in
theory).

Here's the updated news item, which I will be committing very shortly.  
Please note that there is absolutely no version of portage that was not in 
package.mask that would have problems with an EAPI-2 atom in a news item 
because EAPI-2 support was added to portage at the same time as news item 
support (they both appeared in portage 2.1.6).

Please don't. This needs to be figured out properly.
