Re: Heartbeat
Hi Ken,
I have just opened a new JIRA as you suggested.
https://issues.apache.org/jira/browse/PROTON-512
My idea is that there would be one global idle timeout for whole messenger
and this timeout will be used for all connections.
Regards,
Tomas

No, Messenger.setBlocking(True/False) is independent of
Messenger.setTimeout(...).

Re: Heartbeat

Would that force an app to use blocking operations if it desires idle timeout? IOW, should the need for idle monitoring determine the choice of blocking vs non-blocking?
I probably don't fully grasp the implications....

There is already a single per messenger timeout for blocking operations. It
should be a pretty trivial patch to set that same value as the idle timeout
on each connection.
