Sure, one should definitely not be expecting everything to always work without errors. On this we agree for sure. However, when we do decide to intentionally induce errors for reasons we have not done so before, we should weigh the cost of avoiding that with the cost of having it happen. Consider this strawman: - User gets token, it says "expires_at Now+4 hours" - User starts a brief set of automation tasks in their system that does not use python and has not failed with invalid tokens thus far. - Keystone nodes are all updated at one time (AMAZING cloud ops team) - User's automation jobs fail at next OpenStack REST call - User begins debugging, wasting hours of time figuring out that their tokens, which they stored and show should still be valid, were rejected. And now they have to refactor their app, because this may happen again, and they have to make sure that invalid token errors can bubble up to the layer that has the username/password, or accept rolling back and retrying the whole thing. I'm not saying anybody has this system, I'm suggesting we're putting undue burden on users with an unknown consequence. Falling back to UUID for a while has a known cost of a little bit of code and checking junk tokens twice. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
