keystonemiddleware 4.0.0 breaks gnocchi gate

[Mehdi Abaakouk]

Hi,

Telemetry (ceilometer/gnocchi/aodh/clients) gate jobs no longer works since keystonemiddleware 4.0.0 is released.

we got error like:

Traceback (most recent call last):
  File "gnocchi/tests/base.py", line 50, in skip_if_not_implemented
    return func(*args, **kwargs)
  File "gnocchi/tests/base.py", line 330, in setUp

This is occuring because keystonemiddleware shifted from keystoneclient to keystoneauth and so the values here changed slightly. You can fix this by doing keystoneauth1.loading.register_conf_options instead but i'd be more interested in why you need to register these variables outside of auth_token middleware.

As it appears this is from test code can i suggest using the new fixture[1] instead of trying to deal with the opts.

i believe this was fixed by https://bugs.launchpad.net/keystonemiddleware/+bug/1523311

[Steve Martinelli (stevemar)]

looks like the gnocchi gate is up and running again, marking this as invalid for keystonemiddleware

[Corey Bryant (corey.bryant)]

This is a blocker as far as I can tell for mitaka b2 if this is fixed in 4.1.0 of keystomemiddleware but global requirements doesn't allow 4.1.0. Can keystonemiddleware release a new version?

[Corey Bryant (corey.bryant)]

Maybe I'm wrong and the != 4.1.0 was added to global requirements after the b2 release. Note, I think that locks b2 into a keystonemiddleware with performance issues.

[Matt Riedemann (mriedem)]

Yeah, keystonemiddleware 4.1.0 was blocked in global-requirements b/c of another regression in performance that was breaking the neutron gate. There was a workaround in gnocchi on stable/1.3:

https://github.com/openstack/gnocchi/commit/a3d0c7fd02bd7fb3c45f7f963076c64f0c3816b4

So the ceilometer devstack plugin should be pulling that in which caps keystonemiddleware (per gnocchi).
