> Key: PROTON-2027
> URL: https://issues.apache.org/jira/browse/PROTON-2027
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.27.0
> Reporter: Cliff Jansen
> Assignee: Cliff Jansen
> Priority: Major
> Fix For: proton-c-0.28.0
>
>
> The normal cleanup procedure for epoll and win_iocp proactors waits for all
> async activity to complete before freeing memory.
> pn_proactor_disconnect can't actually force a close so it launches a separate
> async activity piggy-backed on the internal wake mechanism of any connections
> to be closed.
> If the disconnect is happening at the same time as a separate thread doing a
> normal close, a new wake can result after concluding there are none left.
> The solution is to mark the connection as "already awake" before entering the
> cleanup code so new wakes are no-ops. The libuv proactor doesn't need this
> as the disconnect function is managed within libuv and never competes with
> the normal close operation.
