Ken Giusti created DISPATCH-2238:
------------------------------------
Summary: 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
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.
