Remaining issues encountered when running with SQLAlchemy 2.0 for real: * Never call str() on a URL and expect it to be meaningful anymore. The password is aggressively obfuscated now (users absolultely wouldn't let us leave it as is) * More utilities and fixtures that were calling begin() within a block that would have already begun * isnot is now called is_not; mocking "isnot" leads into too many weird compat layers * ORM InstrumentedAttribute and internals use __slots__ now, mock seems to not be able to patch methods. Ideally these tests would use a comparator subclass or something * Connection.connection.connection is now called driver_connection, SQLAlchemy keeps the old name available however oslo.db test suite does not appear to tolerate the deprecation warning emitted, so add a compat layer * mapper() is fully removed from 2.0, not sure if there is another not-yet-committed gerrit that removes mapper() [1] https://docs.sqlalchemy.org/en/20/core/engines.html#sqlalchemy.create_engine.params.pool_pre_ping [2] https://docs.sqlalchemy.org/en/20/changelog/changelog_20.html#change-2fe37eaf2295cebd3bb4ee8e5b8c575c [3] https://github.com/sqlalchemy/sqlalchemy/issues/5648 Change-Id: Ifaca67c07f008d8bc0febeecd3e200cc7ee7a4b0
