Hi ALL, 1. Problems : oslo_config provides method CONF.set_override[1] , developers usually use it to change config option's value in tests. That's convenient . By default parameter enforce_type=False, it doesn't check any type or value of override. If set enforce_type=True , will check parameter override's type and value. In production code(running time code), oslo_config always checks config option's value. In short, we test and run code in different ways. so there's gap: config option with wrong type or invalid value can pass tests when parameter enforce_type = False in consuming projects. that means some invalid or wrong tests are in our code base. There is nova POC result when I enable "enforce_type=true" [2], and I must fix them in [3] [1] https://github.com/openstack/oslo.config/blob/master/oslo_config/cfg.py#L2173 [2] http://logs.openstack.org/16/242416/1/check/gate-nova-python27/97b5eff/testr_results.html.gz [3] https://review.openstack.org/#/c/242416/ https://review.openstack.org/#/c/242717/ https://review.openstack.org/#/c/243061/ 2. Proposal 1) Make method CONF.set_override with enforce_type=True in consuming projects. and fix violations when enforce_type=True in each project. 2) Make method CONF.set_override with enforce_type=True by default in oslo_config Hope some one from consuming projects can help make enforce_type=True in consuming projects and fix violations, You can find more details and comments in https://etherpad.openstack.org/p/enforce_type_true_by_default -- ChangBo Guo(gcb) -------------- next part -------------- An HTML attachment was scrubbed...
