tracopt.perm.tests.authz_policy.test_suite failures on trunk (Windows)

[Christian Boos]

Not sure if it's related to one of the recent tickets relative to the authz changes (#12637, #12649 maybe?). In doubt, I created a new ticket.

I get these 3 errors on trunk (r15375):

FAILED (failures=3)

Only with Python 2.7.13 on Windows x64 when running the full test suite.

Executing these tests in isolation, it's fine:

python  setup.py -q test -s tracopt.perm.tests.authz_policy.test_suite

With Python 2.7.9 WSL, it's fine.

I give a few more details on my system, as it seems the error doesn't happen on AppVeyor:
