------------------------------------
Summary: proton-c: a call to pn_messenger_stop can get into an
infinite loop if the remote connection is severed
Key: PROTON-682
URL: https://issues.apache.org/jira/browse/PROTON-682
Project: Qpid Proton
Issue Type: Bug
Reporter: Dominic Evans
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.
