marconi-server in devstack is generating conflicts in openstack-client

[Julien Vey]

While trying to run marconi/zaqar in devstack, I have the following error

http://paste.openstack.org/show/93899/

It happens each time the "openstack" command is used
I can't figure out if it's a problem with the renaming or nit

My local.conf http://paste.openstack.org/show/91043/

mmh, I tried to replicate this issue but I was not able to. What OS were you using? Ubuntu Precise?

[Julien Vey (vey-julien)]

yes, ubuntu precise. The official canonical ubuntu cloud image to be exact.

I also had the problem with this setup https://github.com/julienvey/vagrant-solum-dev/blob/master/local.conf.docker (+enable_service marconi-server)

[Julien Vey (vey-julien)]

after some investigation, I found something.

at this line https://github.com/openstack/python-openstackclient/blob/master/openstackclient/shell.py#L96
the openstackclient iterates over the modules registered, and when I print self.ext_modules, I see this

[........, <module 'zaqarclient.queues.cli' from '/opt/stack/python-zaqarclient/zaqarclient/queues/cli.pyc'>, <module 'marconiclient.queues.cli' from '/usr/local/lib/python2.7/dist-packages/marconiclient/queues/cli.py'>]

both zaqarclient and marconi client are registered and this is certainly why there is a conflict. zaqarclient registers the --os-queues-api-version argument and marconi client try to do the same

[Flavio Percoco (flaper87)]

@Julien: Now that Marconi has been renamed everywhere, does this still happen?

[Flavio Percoco (flaper87)]

btw, you need to use zaqarclient instead of marconiclient.

[Alex Meade (alex-meade)]

The openstack requirements project has both python-marconiclient and python-zaqarclient which try to register the same option in python-openstackclient and this causes the issue. So basically, openstack requirements has conflicting requirements.

This has affected me, any time you install all of global-requirements.txt, openstackclient will be broken.

[Steve Martinelli (stevemar)]

shouldn't the solution be to remove marconiclient? or make marconiclient register a different option? I don't think it's unreasonable that openstackclient fail when the same option is registered twice, we *really* don't want to support that case
