I'm trying to knock out common deprecation messages which are generating noise in the test runs. There is a deprecation message emitted all the time during test runs in Nova which is: DeprecationWarning: Method 'CORS.set_latent()' has moved to 'method.set_defaults()': CORS.set_latent has been deprecated in favor of oslo_middleware.cors.set_defaults" But from what I can see it's primary caller is the cors middleware itself - https://github.com/openstack/oslo.middleware/blob/1cf39ee5c3739c18fed78946532438550f56356f/oslo_middleware/cors.py#L133-L137 At least I'm having a hard time finding anyone else in this stack calling set_latent. Is this just a circular bug on the cors.py module? -Sean -- Sean Dague http://dague.net
