Justin Ross updated PROTON-682:
-------------------------------
Labels: messenger patch (was: )
> proton-c: a call to pn_messenger_stop can get into an infinite loop if the
> remote connection is severed
> -------------------------------------------------------------------------------------------------------

> The problem is that the transport layer is not being closed down properly if
> output is pending when the connection is severed and a messenger stop is
> requested. pn_messenger_stop needs to send out an AMQP close message any will
> only do this when there is an event to say that it can write (i.e
> pn_messenger_process gets a PN_WRITABLE event from pn_selector_next, which
> examines the pollfd and sets PN_WRITABLE event if POLLOUT is set in revents).
> Because this event is never generated it seems to loop forever.
