[rdo-list] RPM (minimum version) dependencies (pike)

[iain MacDonnell]

Experimenting with upgrading RDO Ocata to Pike in my lab, and have run
into a couple of RPM minimum version dependency issues.

1) neutron-server and agents fail to start, with:

# neutron-server
Guru meditation now registers SIGUSR1 and SIGUSR2 by default for
backward compatibility. SIGUSR1 will no longer be registered in a
future release, so please use SIGUSR2 to generate reports.
Traceback (most recent call last):
  File "/usr/bin/neutron-server", line 6, in <module>
    from neutron.cmd.eventlet.server import main
  File "/usr/lib/python2.7/site-packages/neutron/cmd/eventlet/__init__.py",
line 15, in <module>
    eventlet_utils.monkey_patch()
  File "/usr/lib/python2.7/site-packages/neutron/common/eventlet_utils.py",
line 25, in monkey_patch
    p_c_e = importutils.import_module('pyroute2.config.asyncio')
  File "/usr/lib/python2.7/site-packages/oslo_utils/importutils.py",
line 73, in import_module
    __import__(import_str)
ImportError: No module named asyncio


I have:

# rpm -q python2-pyroute2
python2-pyroute2-0.4.8-1.el7.noarch

which meets the dependency:

# rpm -qR python-neutron-11.0.0-1.el7.noarch | grep pyroute2
python-pyroute2 >= 0.4.3


but the latest version (in the openstack-pike repo) is 0.4.19 (and
neutron works after explicitly updating to that). Seems that the
"Requires" in python-neutron needs to be bumped up.


2) Horizon fails to start due to https://bugs.launchpad.net/horizon/+bug/1701765

Per comments in that bug, python-XStatic-Bootstrap-SCSS >= 3.3.7.1 is
required., but we have:

# rpm -qR openstack-dashboard-12.0.0-1.el7.noarch | grep SCSS
python-XStatic-Bootstrap-SCSS


So it seems that the minimum version needs to be added to that "Requires".

I can file a bug (or two) on this if it'd be helpful... ?
