Todd Gamblin d729b4e72b bugfix: installed and installed_upstream should not assert (#30271) ... Fix bug introduced in #30191. `Spec.installed` and `Spec.installed_upstream` should just return `False` for abstract specs, as they can be called in that context. - [x] `Spec.installed` returns `False` now instead of asserting that the `Spec` is concrete. - [x] `Spec.installed_upstream` returns `False` now instead of asserting that the `Spec` is concrete. - [x] `Spec.installed_upstream` no longer caches its result, as install status seems like a bad thing to cache -- it can easily be invalidated. Calling code should use transactions if there are peformance issues, as with other places in Spack. - [x] add tests for `Spec.installed` and `Spec.installed_upstream`		2022-04-25 07:46:21 +00:00
