Hi everyone! It's yet another of these emails where I'm going to complain out of frustration because of OpenStack having bugs when running with the newest stuff... Sorry in advance ! :)
tl;dr: It's urgent, we need Python 3.7 uwsgi + SSL gate jobs. Longer version: When Python 3.6 reached Debian, i already forwarded a few patches. It went quite ok, but still... When switching services to Python 3 for Newton, I discover that many services still had issues with uwsgi / mod_wsgi, and I spent a large amount of time trying to figure out ways to fix the situation. Some patches are still not yet merged, even though it was a community goal to have this support for Newton: Neutron: https://review.openstack.org/#/c/555608/ https://review.openstack.org/#/c/580049/ Neutron FWaaS: https://review.openstack.org/#/c/580327/ https://review.openstack.org/#/c/579433/ Horizon tempest plugin: https://review.openstack.org/#/c/575714/ Oslotet (clearly, the -1 is for someone considering only Devstack / venv, not understanding packaging environment): https://review.openstack.org/#/c/571962/ Designate: As much as I know, it still doesn't support uwsgi / mod_wsgi (please let me know if this changed recently). There may be more, I didn't have much time investigating some projects which are less important to me. Now, both Debian and Ubuntu have Python 3.7. Every package which I upload in Sid need to support that. Yet, OpenStack's CI is still lagging with Python 3.5. And there's lots of things currently broken. We've fixed most "async" stuff, though we are failing to rebuild oslo.messaging (from Queens) with Python 3.7: unit tests are just hanging doing nothing. I'm very happy to do small contributions to each and every component here and there whenever it's possible, but this time, it's becoming a little bit frustrating. I sometimes even got replies like "hum ... OpenStack only supports Python 3.5" a few times. That's not really acceptable, unfortunately. So moving forward, what I think needs to happen is: - Get each and every project to actually gate using uwsgi for the API, using both Python 3 and SSL (any other test environment is *NOT* a real production environment). - The gating has to happen with whatever is the latest Python 3 version available. Best would even be if we could have that *BEFORE* it reaches distributions like Debian and Ubuntu. I'm aware that there's been some attempts in the OpenStack infra to have Debian Sid (which is probably the distribution getting the updates the faster). This effort needs to be restarted, and some (non-voting ?) gate jobs needs to be setup using whatever the latest thing is. If it cannot happen with Sid, then I don't know, choose another platform, and do the Python 3-latest gating... The current situation with the gate still doing Python 3.5 only jobs is just not sustainable anymore. Moving forward, Python 2.7 will die. When this happens, moving faster with Python 3 versions will be mandatory for everyone, not only for fools like me who made the switch early. </end of ranting> :) Cheers, Thomas Goirand (zigo) P.S: A big thanks to everyone who where helpful for making the switch to Python 3 in Debian, especially Annp and the rest of the Neutron team. __________________________________________________________________________ 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
