[jira] [Created] (VYSPER-337) Sequential processing of stanzas per StanzaRelay

Bernd Fondermann created VYSPER-337:
---------------------------------------

             Summary: Sequential processing of stanzas per StanzaRelay
                 Key: VYSPER-337
                 URL: https://issues.apache.org/jira/browse/VYSPER-337
             Project: VYSPER
          Issue Type: Improvement
          Components: stanza routing
    Affects Versions: 0.7
            Reporter: Bernd Fondermann


Currently, StanzaRelays typically act as a "stage", in that they queue and process stanzas.
The most important one probably is DeliveringInternalInboundStanzaRelay.
If multiple stanzas are queued intentionally in a certain sequence (A, B), the relay's queue ensures that processing of stanzas (i.e. assignment to threads from the pool) starts in that sequence.

The weak point is that B's processing can finished before A's. This is not a problem if A is delivered to a different session than B. However, if both, A and B, are delivered to the same session, the sequence has changed, which may be unwanted. (Example: A: presence for a MUC room, B: history message for the same room.)
