Hi > 2. Before submitting the new patch for review it's better to run unit tests (tox -epy27) and pep8 check (tox -epep8) Instead of pep8 I think you should run flake8 we moved to that some months ago[1]. Usually I find always useful to test my changes in devstack. Regards -- Andrea Rosa [1] http://lists.openstack.org/pipermail/openstack-dev/2013-May/009178.html
