Summary: portage requires me to unmask dev-libs/glib-2.32.4 for packages that don't need it

Description kipplasterjoe 2012-08-22 18:06:10 UTC
Today I updated my portage tree and portage version. I cannot do an upgrade because of the following problem:

The following keyword changes are necessary to proceed:
#required by net-libs/farsight2-0.0.29, required by net-im/pidgin-2.10.6[gstreamer], required by @selected, required by @world (argument)
=dev-libs/glib-2.32.4 ~amd64

I figured out that neither net-libs/farsight2-0.0.29 nor net-im/pidgin-2.10.6[gstreamer] require glib-2.32.4!

in the farsight2 ebuild there is ">=dev-libs/glib-2.26:2" required, Pidgin 2.10.6 only needs ">=dev-libs/glib-2.16".

Also i can upgrade the two packages by doing emerge -C and reemerging them. In that case, portage doesn't want glib-2.32.4.

Reproducible: Always

Steps to Reproduce:
1. run emerge -avuDN world
Actual Results:  
portage should keep dev-libs/glib-2.30.3

Expected Results:  
portage requires dev-libs/glib-2.32.4

If you can reproduce the problem then please attach a debug log, created as follows:

   emerge -avuDN world --debug &> debug.log
Comment 2 kipplasterjoe 2012-08-23 09:41:11 UTC
I solved a part of the problem by running "emerge -avuDNt world", x11-misc/lightdm was unmasked on my system and requires dev-libs/glib-2.32.4. Now I did a downgrade to stable lightdm and no longer have the problem.

I think portage should display only packages actually triggering the unmask request.
At the moment it says:

The following keyword changes are necessary to proceed:
#required by net-libs/farsight2-0.0.29, required by net-im/pidgin-2.10.6[gstreamer], required by @selected, required by @world (argument)
=dev-libs/glib-2.32.4 ~amd64

but it means:

The following keyword changes are necessary to proceed:
#required by x11-misc/lightdm-1.3.2, required by @selected, required by @world (argument)
=dev-libs/glib-2.32.4 ~amd64

This is a problem, the user doesn't now which package is responsible for requiring dev-libs/glib-2.32.4.

Yes, that seems like a case of bug 419381.
