Hello everyone,
I am having an issue using the RPCClient of the oslo.messaging package
delivered through the stable/icehouse release of devstack (v 1.4.1).
With this simple script:
########################################################
import sys
from oslo.config import cfg
from oslo import messaging
from project.openstack.common import log
LOG = log.getLogger(__name__)
log_levels = (cfg.CONF.default_log_levels +
['stevedore=INFO', 'keystoneclient=INFO'])
cfg.set_defaults(log.log_opts, default_log_levels=log_levels)
argv = sys.argv
cfg.CONF(argv[1:], project='test_rpc_server')
log.setup('test_rpc_server')
transport_url = 'rabbit://guest:guest@localhost:5672/'
transport = messaging.get_transport(cfg.CONF, transport_url)
target = messaging.Target(topic='test_rpc', server='server1')
client = messaging.RPCClient(transport, target)
ctxt = {'some':'context'}
try:
res = client.call(ctxt, 'call_method_1')
except Exception as e:
LOG.debug(e)
print res

Segmentation fault (core dumped)
The last Python method called is the following one (in librabbitmq package, v
1.0.3):
def basic_publish(self, body, exchange='', routing_key='',
mandatory=False, immediate=False, **properties):
if isinstance(body, tuple):
body, properties = body
elif isinstance(body, self.Message):
body, properties = body.body, body.properties
return self.connection._basic_publish(self.channel_id,
body, exchange, routing_key, properties,
mandatory or False, immediate or False)
The script crashes after trying to call _basic_publish.
For information, I've got the trusty's rabbitmq-server version (v 3.2.4-1).
Plus, replacing the call method by a cast method makes that a message is queued.
Could you please tell me if I'm doing something wrong? Is there a bug in the
c-library used by librabbitmq?
Thanks beforehand,
Romain Ziba.
