* load_template_source(): use io.open() with an encoding instead of open(), to have the same behaviour on Python 2 and Python 3 * assertRedirectsNoFollow(): remove an useless assertion on the response status code which is already tested a few lines below. The assertion used code/100 which returns a float on Python 3, whereas an int was expected. * add_logout_reason(): don't encode reason to UTF-8 on Python 3 * tox.ini: add openstack_dashboard.dashboards.settings.password to Python 3.4 Partial-Implements: blueprint porting-python3 Change-Id: Iff8997917b5d812952150b2abe89ddd12deab0c0
