A Debian Buster-based zuul-jobs test started failing when using stestr
recently [1]. Upon further investigation, this is a Python 3.7
environment which is affected by a recent breaking change to
importlib_metadata.
It seems stevedore worked around this with
Ib9c2b0a14edea91e97d122d2ac93b650029f918e, which was released with
3.5.1 -- but I was still seeing the issue.
Upon further investigation, the "real_groups" dict being returned here
with importlib-metadata 4.12.0 is in buckets by group, e.g.
{'group.one': [EntryPoint(name='foo', ... , group='group.one'),
EntryPoint(name='bar', ... , group='group.one')],
'group.two': [EntryPoint(name='moo', ... , group='group.two'),
EntryPoint(name='goo', ... , group='group.two')],
}
This current code seems to return a dict with entry-points by thier
name, e.g.
{'foo': EntryPoint(name='foo', ... , group='group.one),
'bar': EntryPoint(name='bar', ... , group='group.one),
'moo': EntryPoint(name='moo', ... , group='group.two),
'goo': EntryPoint(name='goo', ... , group='group.two)
}
This reorgansies the fixup routine to put entry-points in a bucket by
their group. With this change, stestr is again finding it's command
plugins.
