Brian Bouterse created PROTON-1466:
--------------------------------------
Summary: Container.create_receiver() does not create all receivers
with certain names
Key: PROTON-1466
URL: https://issues.apache.org/jira/browse/PROTON-1466
Project: Qpid Proton
Issue Type: Bug
Components: python-binding
Affects Versions: 0.17.0
Reporter: Brian Bouterse
On an empty broker create three queues:
{noformat}
qpid-config add queue [email protected]
qpid-config add queue resource_manager
qpid-config add queue [email protected]
{noformat}
Run the reproducer below `python three_consumers.py`
{code:title=three_consumers.py|borderStyle=solid}
from __future__ import print_function
from proton.handlers import MessagingHandler
from proton.reactor import Container
class ThreeConsumers(MessagingHandler):
def __init__(self):
super(ThreeConsumers, self).__init__()
def on_start(self, event):
self.conn = event.container.connect('localhost:5672')
event.container.create_receiver(self.conn,
'[email protected]')
event.container.create_receiver(self.conn, 'resource_manager')
event.container.create_receiver(self.conn, '[email protected]')
def on_message(self, event):
print(event.message.body)
try:
Container(ThreeConsumers()).run()
except KeyboardInterrupt:
pass
{code}
Show the queue stats with:
{noformat}qpid-stat -q{noformat}
Observe that each queue created should have a consumer but it does not. See the
"cons" column.

Note that reordering the create_receiver calls or commenting them out causes
different consumer counts.
