cross-swift-py27 and cross-swift-py36 are failing 3 unit tests

[Jiri Podivin]

The jobs cross-swift-py27 and cross-swift-py36 are failing on the stable/train branch of the openstack requirements project, effectively blocking merging of patches.

In both cases, the unit tests appear to fail due encoding change of the tested string, breaking the test assertion.

[Tim Burke (1-tim-z)]

Should get fixed for train by https://review.opendev.org/c/openstack/swift/+/838589. Starting 3/31, Ubuntu released fixes for https://bugs.python.org/issue43882 across many python versions; many of Swift's stable branches have been busted since then.

[Tim Burke (1-tim-z)]

FWIW, fixes have been merged to

* wallaby - https://review.opendev.org/c/openstack/swift/+/793439
* victoria - https://review.opendev.org/c/openstack/swift/+/838587

with patches proposed to

* ussuri - https://review.opendev.org/c/openstack/swift/+/838588
* train - https://review.opendev.org/c/openstack/swift/+/838589
* stein - https://review.opendev.org/c/openstack/swift/+/838746

[Jiri Podivin (jpodivin)]

All of the patches mentioned by Tim Burke were merged as of April 21.
I can confirm that both of the jobs are now functioning in the stable/train branch.

Marking as Fix released.
