I have added an RFE about starting work on adding static type hint checking to Ironic: https://bugs.launchpad.net/ironic-lib/+bug/1633756 And a starting patch to openstack/ironic-lib: https://review.openstack.org/#/c/386892/ A patch to add the 'typing' package to openstack/requirements/global- requirements.txt: https://review.openstack.org/386944 Issues: I tried adding the 'mypy-lang' package to global-requirements but the tool 'generate-constraints' does not handle "Python 3 only" packages. Or I don't know how to make it handle "Python 3 only" packages. So I added the dep for 'mypy-lang' as a local dep requirement in the tox.ini file. Very interested to hear if anybody else has started working on static type hint checking in their projects. Thanks, John -------------- next part -------------- An HTML attachment was scrubbed...
