Fixed In Version: python-quantumclient-2.2.1-2.el6ost Doc Type: Bug Fix
Doc Text:
Prior to this update, older versions of python-cliff were incompatible with Python 2.6. Consequently, python-quantumclient with Python 2.6 and older python-cliff produced errors. This fix addresses the issue by requiring python-cliff version 1.3 or higher, which provides Python 2.6 compatibility. As a result, python-quantumclient can be used with Python 2.6.

Description Brent Eagles 2013-06-07 18:55:33 UTC 
python-quantum client depends on python-cliff version 1.3 or later to ensure python 2.6 compatibility. 

Earlier versions result in errors like the following:

'module' object has no attribute 'compress'

(see https://bugzilla.redhat.com/show_bug.cgi?id=967297 for initial reported issue)

Additional info:

The python-cliff package is already in the queue to be updated (python-cliff-1.3-1.el6ost).
Comment 2 Brent Eagles 2013-06-20 15:33:56 UTC 
Please note that this bug is only for updating the dependency info in the python-quantumclient spec file to specify python-cliff version 1.3 or newer.
Comment 9 Roey Dekel 2013-10-13 12:06:49 UTC 
I've tried to verified it on Havana running rhel6.5 with:
python-neutronclient-2.2.6-1.el6ost.noarch

Though the python-cliff version is:
python-cliff-1.4.4-1.el6ost.noarch
Which is later then 1.3, but looking at the dependencies of of the neutronclient I saw that it only requiers:
python-cliff >= 1.0
Which might cause problems if it needs 1.3 or later.
Comment 10 Roey Dekel 2013-10-17 07:54:06 UTC 
As I wrote earlier it looks like some repos has been updated which might cause the proper version to be installed (python-cliff-1.4.4-1.el6ost.noarch), but without them, due to current dependency you might find yourself with older version (such as 1.0).
Comment 11 Jakub Ruzicka 2013-10-29 16:47:13 UTC 
We are providing distribution as a whole. If we require feature from python-cliff 1.3, we can just backport the feature to 1.0 (as an example) and in that case there is no reason to require 1.3. No one cares about really checking minimal required version upstream. These are just few reasons why we don't depend on versions if at all possible and instead just provide the right packages. IMHO this bug should be closed as soon as python-cliff 1.3 is available

What do you say, Pádraig, should I explicitly require python-cliff >= 1.3 here? For some reason >= 1.0 is required already.
Comment 12 Pádraig Brady 2013-10-29 17:57:34 UTC 
We should avoid explicit version deps.
The only caveat is where we need to force an update within a RHOS release.
(updates between releases will/should involve a yum update, which will
apply the required update automatically without needing the version dep).
Given RHOS 3.0 and RHOS 4.0 have cliff 1.3 in the repos already,
I'm closing this.
