The test suites for both projects trigger a segfault bug in the 3.4 interpreter as it is shipped on Ubuntu Trusty. The fix for the segfault is already available upstream, and the team at Canonical is working on packaging a new release, but our schedules are out of sync. Maintaining a separate image and pool of testing nodes for 3.3 testing of just these two projects is going to be a bit of a burden, and so the infra team has asked if we’re willing to turn off the 3.3 jobs for the two projects, leaving us without 3.x testing in the gate until the 3.4 interpreter on Trusty is updated.
> The latest word from Canonical is that they plan to package Python 3.4.3, due to be released in about a month. It will take some additional time to put it through their release process, and so there’s some uncertainty about how long we would be without 3.x gate jobs, but it doesn’t look like it will be indefinitely.
> To mitigate that risk, fungi has suggested starting to work on Debian Jessie worker images, which would include a version of Python 3.4 that doesn’t have the segfault issue. His goal is to have something working by around the end of March. That gives Canonical up to a month to release the 3.4.3 package before we would definitely move those tests to Debian. Whether we move any of the other projects, or would move anyway if fungi gets Debian working more quickly than he expects, would remain to be seen.
> Although we do have some risk of introducing Python 3 regressions into the two libraries, I am inclined to go along with the infra team’s request and disable the tests for a short period of time. The rootwrap library doesn’t see a lot of changes, and we can rely on the messaging lib devs to run tests locally for a little while.

I’m not involved with those two subprojects but as an Oslo member I’d +1 disabling python3.x for now.
