[C++ Broker] Ring queue does not properly implement byte size limits


    • Type: Bug

      To test I created a queue on the C++ broker with a size limit of 512 bytes, and a policy of "ring"

      First I sent 5 messages each of size 100 bytes.
      Then I sent a 6th 100 byte message - as expected this dequeued one of the existing messages

      next I sent a single message of size 400 bytes
      This caused only a single existing message to be dequeued, leading to 5 messages being enqueued with a total depth of 900 bytes (as reported by qpid-tool). At this point I would have expected all but one of the existing messages to have been dequeued in order to make room for the 400 byte message

      Finally I sent a single 1000 byte message. This message in itself should have been too big for the queue, however it was enqueued; and only one 100 byte message was dequeued - leaving a total byte depth of 1800 bytes being enqueued.
