Hi, We are working on a blueprint<https://blueprints.launchpad.net/nova/+spec/add-extra-specs-to-flavor-list>, which adds extra specs to the flavor show and detail calls. As a part of this, we have added a new extension called FlavorWithExtraSpecs. When this extension is enabled, the extra_specs of the flavor will be included as part of the response. Since this extension will add extra fields (extra_specs of the flavor) to the response, the clients consuming this API will have to support the same. Ideally none of the clients should fail, but we found the tempest tests on gerrit fail because the response has a new key which is not handled by the existing flavor format method. We have made the required code fixes to tempest and it is in review<https://review.openstack.org/#/c/40384/> . With this extension loaded, we will now see an extra field in the response. Do you have any concerns with the approach we have taken? Thanks, Aditi -------------- next part -------------- An HTML attachment was scrubbed...
