From db3e166503386b4f9e456017fd56d8bce84528fe Mon Sep 17 00:00:00 2001 From: Bryan Ischo Date: Mon, 9 Mar 2009 09:56:13 +1300 Subject: Look in target-list first to resolve dependencies This fixes a bug introduced by my previous changes which changes the behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable packages from the transaction. The bug is that the target-list was no longer being consulted first to resolve dependencies, which means that if two packages in the sync database satisfied a dependency, and the user explicitly requested one of those two packages in the sync, the other package was still being pulled in. A new test was added, sync993.py, to verify the desired behavior.
