-----------------------------------
Summary: [proton-c, regression] PN_CONNECTION_BOUND event is
emitted too soon
Key: PROTON-1745
URL: https://issues.apache.org/jira/browse/PROTON-1745
Project: Qpid Proton
Issue Type: Bug
Affects Versions: proton-c-0.20.0
Environment: Fedora 27
Reporter: Chuck Rolke
During a PN_CONNECTION_BOUND event proton socket information is not available.
At PN_CONNECTION_REMOTE_OPEN the info is available.
I instrumented an event loop in qpid-dispatch to log the event names as they
are delivered and to log the result of creating a qd_connection rhost_port
name. The source:
{noformat}
case PN_CONNECTION_BOUND:
on_connection_bound(qd_server, e);
// HACK ALERT
pn_connection_t *pn_conn = pn_event_connection(e);
qd_connection_t *qd_conn = pn_connection_get_context(pn_conn);
set_rhost_port(pn_conn, qd_conn);
qd_log(qd_server->log_source, QD_LOG_CRITICAL,
"At end of connection bound the name is: %s",
qd_connection_name(ctx));
// END HACK ALERT
break;
case PN_CONNECTION_REMOTE_OPEN:
{
// HACK ALERT
pn_connection_t *pn_conn = pn_event_connection(e);
qd_connection_t *qd_conn = pn_connection_get_context(pn_conn);
set_rhost_port(pn_conn, qd_conn);
qd_log(qd_server->log_source, QD_LOG_CRITICAL,
"At entry to remote open the name is: %s", qd_connection_name(ctx));
/// END HACK ALERT
{noformat}
The log file shows:
{noformat}

PN_CONNECTION_REMOTE_OPEN (/home/chug/git/qpid-dispatch/src/server.c:845)
2018-01-17 12:38:35.224971 -0500 SERVER (critical) At entry to remote open the
name is: 127.0.0.1:46722
(/home/chug/git/qpid-dispatch/src/server.c:895){noformat}
The "err -6" is a snoop on the return result of getnameinfo(): EAI_FAMILY
'ai_family' not supported. I suspect it's because the returned socket is junk.
The code works correctly in 0.19.0, commit fe3c3
