> Avoid holding the core action lock when waking the core thread
> --------------------------------------------------------------
>
> Key: DISPATCH-2238
> URL: https://issues.apache.org/jira/browse/DISPATCH-2238
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Affects Versions: 1.17.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Minor
> Fix For: 1.18.0
>
>
> Currently when an action is queued for the core to process, the queuing code
> calls pthread_cond_signal() while holding the associated mutex. This can
> cause the core thread to be woken then immediately put sleep while taking the
> mutex.
>
> It is legal to call pthread_cond_signal() without holding the lock. Doing
> this will avoid contention on the associated mutex.
