Public bug reported: If you PUT some allocations for a new consumer (thus no generation), and those allocations are against more than one resource provider, a 409 failure will happen with:
consumer generation conflict - expected 0 but got None This because in _new_allocations in handlers/allocation.py we always use the generation provided in the incoming data when we call util.ensure_consumer. This works for the first resource provider but then on the second one the consumer exists, so our generation has to be different now. One possible fix (already in progress) is to use the generation from new_allocations[0].consumer.generation in subsequent trips round the loop calling _new_allocations. I guess we must have missed some test cases. I'll make sure to add some when working on this. I found the problem with my placecat stuff. ** Affects: nova Importance: High Assignee: Chris Dent (cdent) Status: New ** Tags: placement -- You received this bug notification because you are a member of Yahoo!
