Open Stack

Hi,

There's jsonschema 2.0.0 in Sid, and when I build some of the OpenStack
packages, I get a huge list of requirement parsing errors:

2013-09-12 17:05:55.720 26018 ERROR stevedore.extension [-] Could not
load 'file': (jsonschema 2.0.0 (/usr/lib/python2.7/dist-packages),
Requirement.parse('jsonschema>=0.7,<2'))
2013-09-12 17:05:55.720 26018 ERROR stevedore.extension [-] (jsonschema
2.0.0 (/usr/lib/python2.7/dist-packages),
Requirement.parse('jsonschema>=0.7,<2'))

Though, when I have a look at the requirements.txt and
test-requirements.txt of nova, jsonschema has:

requirements.txt: jsonschema>=1.3.0,!=1.4.0

This seems to be fine, so I don't understand what is conflicting. Doing
a "grep -r jsonschema" on the nova sources gives no result.

So my questions are:
- what is creating these parse errors, and how to fix them?
- could we make it so that OpenStack supports jsonschema 2.0.0, which is
now in Sid? Where should I look into then?
- why do we have the above error, while global-requirements.txt doesn't
ping jsonschema to <2?

I would very much like to have this resolved, since that's completely
destroying the unit test results of multiple Debian packages for Havana
b3, including Nova.

Cheers,
