CatchErrorsMiddleware is also imported to ensure all internal exceptions are caught outermost. api-paste.ini is updated to use them. KeystonAuthContext middleware is updated so that it uses request-id generated by RequestIdMiddleware. Add middleware to openstack.conf and import all modules under middleware directory from oslo. DocImpact UpgradeImpact This patch adds new WSGI middlewares "request_id" and "catch_errors". They needs to be added to api-paste.ini when upgrading.
