Ihar Hrachyshka f69389004a Revert "Revert "Automatically expire obsolete relationships"" ... This reverts commit a75014792a. This is the second attempt to merge the patch after the previous one resulted in revert due to multiple gate breakages in dependent projects (neutron-lbaas, vmware-nsx, heat, networking-odl). This second attempt is validated with a set of depends-on patches for all projects that were affected during the first failed attempt. The original commit message for the patch is included below for context. === Listen for foreign key changes and expire related relationships. With this, we can remove OVO code that refreshes / detaches models on each fetch. The patch also removes a bunch of expunge calls in plugin code. writer.using context manager is added to _get_subnets so that segment plugin's _notify_subnet_updated handler that calls to _get_subnets doesn't use the facade-less context.session that in specific cases may cache old models from previous sessions when used in mixed facade/facade-less environment. This patch bumps SQLAlchemy minimal requirement to >= 1.2.0 because pending_to_persistent event didn't exist before this version. It could be >= 1.1.0 if not for the fact that all 1.1.x releases have a bug that results in breakage of test_update_with_none_and_own_mac_for_duplicate_ip due to obscure import ordering issue in the library. (The issue is fixed by https://github.com/zzzeek/sqlalchemy/commit/ 63ff0140705207198545e3a0d7868a5ba8486e93) Partially-Implements: blueprint enginefacade-switch Partially-Implements: blueprint adopt-oslo-versioned-objects-for-db Co-Authored-By: Michael Bayer <mike_mp@zzzcomputing.com> Depends-On: If4b28110f460f6ac77ace1bbb02967ea986d4cab Depends-On: I9f1e76cb24838533572b5fbe269ff96a24ce4af1 Change-Id: I0d65d19204da8ce30addfa5faff68544534b7853		2018-04-26 22:04:07 +00:00
