[Openstack-devel] Bug#732367: Ceilometer 2013.2.1 depends on WSME>=0.5b5, <0.5b6

[Gaudenz Steinlin]

Package: ceilometer
Version: 2013.2.1-1
Severity: grave

Starting ceilometer-collector, ceilometer-agent-central or 
ceilometer-api leads to an error containing the following 
stacktrace (not at the end but this is the point where it fails):

This is due to the fix for the following bug in ceilometer:
https://bugs.launchpad.net/wsme/+bug/1240741

The bug above was already present in earlier version of ceilometer. It's now 
just more obvious as ceilometer refuses to run with an incompatible
version of WSME. Unfortunately the incompatible version of WSME is
already in Debian unstable and testing.

I see two options to resolve this bug:

1) Make ceilometer compatible with WSME>=0.5b6 by cherry-picking commit
   e4a1a4fcefd4718e057cf8128c9a6c6b7c98ef59 from upstream. I'm currently
   building a test package to see if that works.
2) Downgrade python-wsme to 0.5b5 with an epoch.

The first option is a bit more forward looking by fixing the actual
problem, while the second option avoids a diff to the official havanna
release of OpenStack.
