Ed, does this bug exist in lbaas v2 as well? The code in master and other branches for undeploy_instance() in neutron_lbaas/drivers/haproxy/namespace_driver.py is very similar.

Also, can we drop the target for trusty-icehouse or do we need to keep that target?

If this is also a bug for lbaas v2, I'd like to see if we can get that fixed upstream/backported first.

Hi Corey, this bug only applies to the v1 driver and since we still support it (since it is the default in Kilo - our mid-term lts) we are applying this fix from Kilo up to the point prior to the v1 driver being removed from upstream in Newton. For the record, it is recommended that people use the v2 driver as of Liberty. So there's no need to fix anything upstream and no need to apply this beyond Mitaka.

And to be clear, there was a similar bug in the v2 driver that has been subsequently fixed as part of bug 1495430. We can backport that separately.

Ed, here's the v2 code I was thinking may also be affected. I don't know the code well but it seems to be the same function as is in v1, so that's why I was thinking this affects v2 as well. But maybe this is dead code or fixed elsewhere in v2?

See 'if delete_namespace:' at: https://github.com/openstack/neutron-lbaas/blob/master/neutron_lbaas/drivers/haproxy/namespace_driver.py#L161

Corey, the code is a little confusing since they split the codebase between v1 and v2 but most modules have the same names. The code that you point to there is the v2 driver. You won't actually find the v1 code in master anymore since it was completely removed in Newton but if you go back to mitaka you can find it in https://github.com/openstack/neutron-lbaas/tree/stable/mitaka/neutron_lbaas/services/loadbalancer/drivers.

Thanks for the explanation Ed. It looks like this is fixed for v2 in bug 1495430.
