[Bug 1800601] Re: [SRU] Infinite recursion in Python 3

[Liam Young]

Just to be clear, when I say I'm hitting it I mean I'm hitting it on a
deployed system, not just in unit tests.

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. 

  [Test Case]

  
  [Regression Potential]
  Fairly low. The patch is a minimal fix and will be fully exercised by the OpenStack charms team.
