Todd Gamblin e0c3d074c0 bugfix: handle hashes that only exist in input specs ... In our tests, we use concrete specs generated from mock packages, which *only* occur as inputs to the solver. This fixes two problems: 1. We weren't previously adding facts to encode the necessary `depends_on()` relationships, and specs were unsatisfiable on reachability. 2. Our hash lookup for reconstructing the DAG does not consider that a hash may have come from the inputs.		2021-11-05 00:15:47 -07:00
