PROTON-2763: Raw connection double DISCONNECT event
> Two final disconnect events possible from a raw connection
> ----------------------------------------------------------
>
> Key: PROTON-2763
> URL: https://issues.apache.org/jira/browse/PROTON-2763
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.39.0
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
>
> In writing a new threaderciser for raw connections the following scenario can
> result in a state machine mixup and second disconnect.
> If a pn_raw_connection_wake() occurs around the time that the first
> disconnect event is being consumed the task may be added to the global ready
> list for processing. The batch done() processing will (correctly) defer the
> task cleanup until the task is next scheduled via the ready list. However
> the raw connection forgets that it has already done the disconnect and
> restarts the state machine at the first disconnect stage, resulting in the
> second disconnect event.
