Description Zane Bitter 2017-10-26 11:59:43 EDT

In Pike, Heat loads any attribute values required to serve an API call at the beginning of the call. If an exception occurs loading any of these values, then the API call will fail.

An error in an output of a nested stack causes an exception to be raised in the parent stack if that output is referenced as an attribute of the parent resource. Thus, once this occurs showing the root stack with output resolution will fail, as will operations like stack updates.

Backport is merged to stable/pike upstream.
