The database related functional tests would not work. Several changes were required to fix them: * Clean up permissions in function post_test_hook Without this tox can't create its .tox directories. We want to be running as user stack against a directory owned by user stack. We need to check for a directory named 'devstack' not a file in order to get the permissions changes to happen. * Call pg_ctl initdb, not initdb to create the postgresql database. * Add a DRIVER_MANAGER for mysql+pymysql (without this all mysql tests are skipped, even in the unit tests). * Change get_connection so it doesn't split on + when looking up storage extensions, as we do want to use pymysql. * Make sure AODH_BACKEND is set and exported in gate_hook.sh * Mysql requires a database exist when we name it in a sql create_engine, replace the placeholder with '' when in mysql. * Move keystonemiddleware config to the correct section of the paste file, temporarily.
