Description Juergen Rose 2013-02-19 12:49:49 UTC
'emerge --depclean' does not try to remove old gentoo-sources:

root@condor:/usr/src(63)# qlist -Iv sources
gnome-extra/zeitgeist-datasources-0.8.0.1
kde-base/kdepim-kresources-4.10.0
sys-kernel/gentoo-sources-3.7.3
sys-kernel/gentoo-sources-3.7.4
sys-kernel/gentoo-sources-3.7.6
sys-kernel/gentoo-sources-3.7.8
sys-kernel/vanilla-sources-3.8.0
virtual/linux-sources-1

root@condor:/usr/src(64)# emerge -p --depclean | grep sources
root@condor:/usr/src(65)# 

'emerge -p --depclean =gentoo-sources-3.7.3' works:

root@condor:/usr/src(65)# emerge -p --depclean =gentoo-sources-3.7.3 =gentoo-sources-3.7.4 =gentoo-sources-3.7.6 =gentoo-sources-3.7.8

BTW., why is =gentoo-sources-3.7.8 removed by 'emerge --depclean gentoo-sources-3.7.8'?  gentoo-sources-3.7.8 is the most current version of gentoo-sources.

Before doing the last command (emerge -p --depclean =gentoo-sources-3.7.3 =gentoo-sources-3.7.4 =gentoo-sources-3.7.6 =gentoo-sources-3.7.8) I found in /var/lib/portage/world:

root@condor:/root(19)# grep sources /var/lib/portage/world
sys-kernel/gentoo-sources
sys-kernel/gentoo-sources:3.7.4
sys-kernel/gentoo-sources:3.7.6
sys-kernel/vanilla-sources

After doing 'emerge -p --depclean =gentoo-sources-...) I find:
root@condor:/root(21)# grep sources /var/lib/portage/world
sys-kernel/vanilla-sources
root@condor:/root(22)# 

I.e., gentoo-sources disappeared now completely from /var/lib/world.

You should use --prune to do the job.

You requested for it to remove all of your installed versions of gentoo-sources. In order to do that, it must remove the sys-kernel/gentoo-sources atom from your world file. This is normal behavior, unless you specify --deselect=n. I suspect that you really want to use `emerge --prune gentoo-sources`, as suggested in comment #2.

> I.e., gentoo-sources disappeared now completely from /var/lib/world.

Right, this is an intended consequence of the default --deselect behavior of --depclean.

OK, I can do 'emerge --prune package'. But in the past the old versions of vanilla-sources and gentoo-sources have been removed with 'emerge --depclean'.
Why this behaviour has been changed?

It hasn't changed, but it varies depending on the content of your world file, and depending on the --depclean argument atoms. Any atoms that you feed to --depclean are eligible for removal from world unless you specify --deselect=n. If you don't feed it any atoms, it won't remove any atoms from your world file.

I guess the most common usage scenario is to have sys-kernel/gentoo-sources in /var/lib/portage/world, and to run --depclean with no argument atoms. In that case, it will remove all but the latest version of gentoo-sources (similarly to --prune).

This is the behaviour, which I expect. Mostly I have only sys-kernel/gentoo-sources in /var/lib/portage/world. At "condor" I have sys-kernel/gentoo-sources and sys-kernel/vanilla-sources in /var/lib/portage/world. Usually I do 'emerge -p --depclean' to see, which packages are ready for removal and then I remove some of these packages with "emerge --depclean pkg1 pkg2 ...". But today 'emerge -p --depclean' shows me only some old vanilla-sources packages for removal and not any gentoo-sources package. On the other hand there have been several old gentoo-sources packages. That's why I was estonished. Maybe the reason was that these packages were with version numbers in /var/lib/portage/world:

> root@condor:/root(19)# grep sources /var/lib/portage/world
> sys-kernel/gentoo-sources
> sys-kernel/gentoo-sources:3.7.4
> sys-kernel/gentoo-sources:3.7.6
> sys-kernel/vanilla-sources

But I do not know, why. I suppose, that I never did something like "emerge =gentoo-sources:3.7.4".

Yes, certainly.

Atoms like these will be added to world if you do something like "emerge =gentoo-sources-3.74". In this case emerge automatically generates a SLOT atom, since that's typically what people want if they use a command like this without --oneshot.

There is no bug here, is there?
