There are two issues with supercedent pipelines related to circular deps: 1) When operating in a post-merge configuration on changes (not refs), the pipeline manager would throw an exception starting with 10.0.0 because any time it operates on change objects, it attempts to collect the dependency cycle before enqueing a change, and starting with 10.0.0, the supercedent manager raises an exception in that case. 2) When operating in a pre-merge configuration on changes, the behavior regarding circular dependencies was undefined before 10.0.0. It is likely that they were ignored because the manager creates a dynamic queue based on the project-ref, but it wasn't explicitly documented or tested. To correct both of these: Override the cycleForChange method in the supercedent manager so that it always returns an empty cycle. Document the expected behavior. Add tests that cover the cases described above. Change-Id: Icf30d488334d40a929f31c2f390e18ae599a3c42
