Bug description:
Hi,
When running unit tests under Python 3.7 when building the Rocky
Debian package in Sid, I get a never ending recursion. Please see the
Debian bug report:
https://bugs.debian.org/911947
Basically, it's this:
| File "/build/1st/glance-17.0.0/glance/domain/__init__.py", line 316, in keys
| return dict(self).keys()
| File "/build/1st/glance-17.0.0/glance/domain/__init__.py", line 316, in keys
| return dict(self).keys()
| File "/build/1st/glance-17.0.0/glance/domain/__init__.py", line 316, in keys
| return dict(self).keys()
| RecursionError: maximum recursion depth exceeded while calling a Python object
== Ubuntu SRU details ==
[Impact]
An infinite recursion error occurs when running Python 3.6 glance from rocky. This issue has also been seen when running python 3.7 unit tests.
The error has also been seen in a Rocky deployment and causes the glance api service to return 500 errors.
[Test Case]
Bionic (cloud-archive): Deploy the glance charm on bionic then upgrade it to rocky by updating the openstack-origin to cloud:bionic-rocky/proposed
Cosmic: Note that for cosmic we don't have the ability to test an upgrade from queens to rocky like we can on bionic so we'll just manually test the python3 code.
[Regression Potential]
Fairly low. The patch is a minimal fix and will be fully exercised by the OpenStack charms team.
