Subject [jira] [Commented] (QPID-8075) BrokerAgent not working for me
Date Wed, 24 Jan 2018 23:06:00 GMT

    [ https://issues.apache.org/jira/browse/QPID-8075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16338390#comment-16338390

ASF subversion and git services commented on QPID-8075:
-------------------------------------------------------

Commit e37969a8c19da7aa1c6400af2facecfec6b5f702 in qpid-cpp's branch refs/heads/master from
[~kpvdr]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-cpp.git;h=e37969a ]

QPID-8075: Fixed issue by changing the correlation-id sent to QMF from a 8-byte binary to
a 4-byte string. Now works in Python 2 and Python 3.

>          Components: QMF
>    Affects Versions: qpid-cpp-1.37.0
>         Environment: Fedora 25, fully up to date
> via dnf I installed:
> qpid-proton-c-0.17.0-5.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.

> 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()

line 292, in wait
>     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.
