Send timeout in proton C++

[ali hadi <al...@gmail.com>]

Hello,



Our messaging topology uses a dispatch-router in front of many Java brokers.

In the case where all our brokers are down, we want to throw an exception
to the producer after a timeout. This is not possible with the idle-timeout
parameter since the producer is connected to the dispatch router which is
still responding.

Is there an equivalent to the JMS send timeout parameter or a way to not
let the producer hanging forever in proton C++?



Regards,

Ali

That last clause is a little clumsily worded. What I mean is that if the 
transfer has already been sent and you are just waiting for the ack, 
then stopping the container will just stop waiting for the ack.

Ah, that I'm afraid cannot be done.

Even stopping the container won't actually 'stop' the send, it will just 
prevent processing of any acknowledgement if it does arrive.

(You *can* set a TTL on the message, but once transferred you can't 
cancel it in anyway; the protocol has no support for that).

The action I want to take is to stop the send. Is there a way other than stopping the container to do this ? For example, during the receive, we are using the drain function after the timeout to stop receiving.

Thanks,
Ali

No, but you can implement a timeout like that using the schedule() method on the container. On sending a message, schedule a check on the return tracker after the appropriate timeout. If when that fire the delivery the tracker refers to has not been settled, you can take whatever action needed to handle the timeout.
