Every time I run a large chunk of neutron unit tests, for
example:
$ tox -e py310 -- neutron.tests.unit.plugins.ml2.drivers
I see this warning (it doesn't cause a failure):
Captured stderr:
~~~~~~~~~~~~~~~~
.../neutron/.tox/py310/lib/python3.10/site-packages/ovs/db/idl.py:1484:
DeprecationWarning: The 'warn' method is deprecated, use 'warning' instead
vlog.warn("error parsing column %s in table %s: %s"
Looking at the OVS python library code it seems perfectly fine.
Backtracking, I was able to find the offending code that
actually lived in ovsdbapp. It is a little bit obfuscated
as it was re-mapping the OVS library vlog.Vlog.warn() call
to log.warn(), but I was able to test my theory by modifying
code in my local neutron .tox directory and the warning
went away.
I was never able to narrow things down to a single test, or
class, or file, even running with '--concurrency 1', so I
do not know exactly how this code is getting exercised,
there could be a test that is not cleaning-up properly,
maybe some day we will figure that out.
TrivialFix but not TrivialToFind
