Bug 233253 – Portage 2.2_rc3/4: emerge -uD world doesn't downgrade packages after removing an overlay

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Sven Grunewaldt 2008-07-29 11:12:49 UTC]

I removed the gnome overlay via "layman -d gnome", now Portage doesn't downgrade the packages when executing "emerge -uDN world"

A direct rebuild call wants to downgrade:
emerge -pv gvfs:
[ebuild     UD] gnome-base/gvfs-0.2.5-r1 [0.99.3]

emerge -upv gvfs:
Total: 0 packages, Size of downloads: 0 k

Reproducible: Always

Steps to Reproduce:
1. layman -d gnome
2. emerge -uDpv world

Actual Results:  
Portage only wants to upgrade new packages.

Expected Results:  
Portage should also downgrade every package which lost it's newer ebuild.

I suppose we can implement this as a package set. There's no reason to downgrade those packages unless explicitly told to do so.

[Comment 2 Zac Medico 2008-07-31 12:50:57 UTC]

I've implemented a @downgrade set which selects packages for which the highest visible ebuild version is lower than the currently installed version.

[Comment 3 Zac Medico 2008-08-01 11:14:20 UTC]

This is fixed in 2.2_rc6.
