The entire Launchpad test suite now passes on Python 3. There are some unreliable tests due to Python 3.5 having non-deterministic dict ordering; I've been squashing these as they show up, but we may still run into more. I've also upgraded our "dogfood" instance (https://dogfood.paddev.net/) to Python 3. This is used mainly for QA of the archive publisher, but it's a start. I expect to upgrade staging and qastaging over the next week or two, shake out as many remaining issues as possible, and aim to upgrade production (perhaps gradually) by the end of the 21.04 cycle. At this point I would recommend that all developers have a Python 3 setup available; you may even want to work in it routinely, although you'll still need to run tests on Python 2 before proposing merges. You can maintain both setups quite easily using git worktrees. -- Colin Watson (he/him) [cjwat...@canonical.com] _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
