Description Vladimir Berezhnoy 2011-10-02 13:54:59 UTC
Now it shows all descending dependencies, such lists can be very lengthy. It should limit to those packages which are contained in world file.
Attached log is 4k lines long which makes it pretty useless.

Comment 2 Sebastian Luther (few) 2011-10-02 14:02:16 UTC
What concerns the merge list, no it should display all packages that are about to be installed. 

A problem with your output is that it shows too many parents for the slot conflict message.

Does this still happen if you update portage first?
(emerge -1u portage and then run your command again)
Comment 3 Vladimir Berezhnoy 2011-10-02 16:02:48 UTC
sys-apps/portage- gives the same output
Comment 4 Sebastian Luther (few) 2011-10-02 17:18:00 UTC
I miss read it. It's not a slot conflict, but blocked packages. This is a long standing issue.

What we should do is to use the same parent selection algorithm the slot conflict handler uses.
Comment 6 Zac Medico gentoo-dev 2011-10-05 17:42:02 UTC
This is fixed in and 2.2.0_alpha61.
