Previously in the SchedulerReportClient, _get_provider_aggregates and _get_provider_traits would log a warning and return None on placement API errors. The callers were ignoring these errors, resulting in the internal ProviderTree representation potentially being out of sync with reality. With this change set, these two methods raise exceptions on API errors. As currently implemented, these errors will bubble up into the resource tracker and compute manager in the same way as other unhandled exceptions. That is, they land in the trap in update_available_resource_for_node, where they are logged and otherwise ignored. Why is this an improvement? Because at least the routine that encountered the error doesn't continue on as if nothing went wrong. (We could have dealt with this by having the callers check for None explicitly, but this approach was deemed more rigorous and robust.)

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:
