Releasing

Before you intend to release a new version of neutron-lib consider posting a sentinel patch that will allow to validate that the neutron-lib hash chosen for tagging is not breaking gate or check jobs affecting a project you care about, first and foremost Neutron.

As the patch shows, upper-constraints must be bypassed and that may itself lead to failures due to upstream package changes. The patch also shows (expected) Grenade failures in that Grenade pulls its own upper-constraints file during the upgrade phase. In general a newer version of neutron-lib is validated through the Tempest -full job (and Grenade runs a subset of it), so Grenade failures can be safely ignored.

In any other case consider (for failures caused by unpinned global requirements) hard-coding a dummy upper-constraints file that itself uses the specific neutron-lib hash you want to test. Furthermore, consider using a commit header that starts with DNM (Do Not Merge) to indicate that the change is just a test, or -2, if you have the right access permissions.

It is also worth noting that every Stadium project will have a periodic job running unit tests and pep8 against the master version of neutron-lib (periodic-neutron-py35-with-neutron-lib-master being an example). Checking Grafana’s periodic dashboard can give you a glimpse into the sanity of the integration between neutron-lib and the Stadium projects, and can be considered the quick check before going ahead with a full blown sentinel patch. Periodic failures can be debugged by viewing the periodic logs
