Todd Gamblin 558cf7e406 spec flatten, normalize, validate; package validate ... New operations for manipulating spec and package DAGs. For specs: flatten: gather all deps to the root normalize: Merge constraints and make spec match package DAG For packages: validate_dependencies: Make sure spec constraints in package DAG are sane. Added tests for above methods. Also added beginnings of concretization logic, to turn abstract spec into a concrete one. Still need proper tests for normalize().		2013-10-17 14:46:00 -07:00
