The suds-jurko library used by oslo.vmware is emitting the following warnings in nova tests. /nova/.tox/py36/lib/python3.6/site-packages/suds/resolver.py:89: DeprecationWarning: invalid escape sequence \% self.splitp = re.compile('({.+})*[^\%s]+' % ps[0]) /nova/.tox/py36/lib/python3.6/site-packages/suds/wsdl.py:619: DeprecationWarning: invalid escape sequence \s body.parts = re.split('[\s,]', parts) These warnings are going to be errors in Python 3.10 [1]. We have over 18 months before we need to worry about this [2], but I'd like to see some movement on this well before then. It seems the suds-jurko fork is dead [3] and movement on yet another fork, suds-community, is slow [4]. How difficult would it be to switch over to something that does seem maintained like zeep [5] and, assuming it's doable, is anyone from VMWare/SAP able to do this work?
