[QPID-8075] BrokerAgent not working for me

• Type: Bug
• Status: Closed
• Priority: Blocker
• Resolution: Fixed
• Affects Version/s: qpid-cpp-1.37.0
• Fix Version/s: qpid-cpp-1.38.0
• Component/s: QMF

Environment

Fedora 25, fully up to date
via dnf I installed:
qpid-proton-c-0.17.0-5.fc25.x86_64
qpid-cpp-server-1.36.0-1.fc25.x86_64

pip freeze in my virtual environment is:
python-qpid-proton==0.19.0
qpid-tools==1.37.0

Note this is with Python 3.5.4

Note that qpid-tools is a checkout that includes this commit 0ffa89e177346e68bdeb5a24b9f25190c983bd34 because I need it, and the version on PyPI does not include it.

Description

1. Start qpidd and verify that it starts
2. Verify it's listening on 5762 using `sudo netstat -planet | grep 5672`
3. Telnet connect to it with `telnet localhost 5672` observe that it connects

Try to connect it to with qmf.BrokerAgent

from qmf.client import BrokerAgent, ReconnectDelays
conn_opts =

{'url': 'amqp://localhost:5672'}

ba = BrokerAgent.connect(**conn_opts)
ba.getAllQueues()

I get this exception after 10 seconds:

File "/home/vagrant/devel/kombu/kombu/transport/qpid.py", line 586, in exchange_declare
self._broker.addExchange(type, exchange, options)
File "/home/vagrant/.virtualenvs/pulp/lib64/python3.5/site-packages/qmf/client.py", line 344, in addExchange

raise Timeout(txt)
proton.Timeout: Connection amqp://localhost:5672 timed out: Waiting for response

What is interesting is that on the same system with simply_send.py (the standard example) it connects and sends with the exact same url. I do that with this:

(pulp) [vagrant@pulp3 devel]$ python simple_send.py --address 'amqp://localhost:5672' -m 1
all messages confirmed

The 'all messages confirmed' suggests that everything went fine and the reactor called on_accepted().

So I conclude that BrokerAgent is somehow fundamentally not working or my environment is screwed up somehow.

This same commit checkout was working with Python 2.7. I don't have that environment handy currently, but I suspect this is somehow broken with Python 3.
