Prior to this patch placement was using the nova FaultWrapper middleware as a final guard against unexpected exceptions. That middleware does more than required and also imports stuff that placement does not otherwise require. The new middleware is only for exceptions that have fallen through previous handling and need to be turned into 500 responses, formatted to JSON, and logged. While doing this it became clear that the limited Exception catching in handler.py was redundant if FaultWrapper and the Microversion middlewares (both required for the operation of the system) are involved, so that has been removed, with a comment. This should not require a microversion as the structure of successful responses and expected error responses does not change. What does change is that a 500 response will be formatted more as the api-wg errors guideline[1] desires.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
