Though not directly related to the above, it's worth noting new deprecation introduced in webob 1.2

https://lists.launchpad.net/openstack/msg08387.html

Also worth nothing for EPEL6:
https://lists.launchpad.net/openstack/msg08387.html
" Since Python < 2.7 does not ignore DeprecationWarning, and I am running on Python 2.6, the warnings are being thrown as exceptions."

False alarm: that was webob 1.2 throwing exceptions, not python version difference https://lists.launchpad.net/openstack/msg08416.html

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

But that's webob code using own deprecated stuff, not Keystone, moving component to WebOb for further discussion.

AFAIK this issue still stands on Fedora 17 (or any distro using webob 1.1).

From the webob docs:

http://docs.webob.org/en/latest/news.html

webob 1.1.1:

 Deprecate Response.request and Response.environ attrs.

Furthermore it looks like this has been reversed in webob 1.2a1+:

 Response.request and .environ attrs are deprecated and raise exceptions when used.

This issue could be really annoying in a production deployment of OpenStack because keystone is such a central component. This deprecation warning gets logged into /var/log/messages and I can see it exhausting disk space quite easily.

Ricky, do you mind carrying that patch in f18 rpm?
Would you consider to update webob to 1.2.3 in f19 and f18?

Note f17 probably should be updated along with f18 for consistency.

Note also that updating to 1.2.3 is a bit complicated as we currently have:

          F16 F17 F18 F19 EL5 EL6 RHEL6
webob-0.9                  *        *
webob-1.0  *
webob-1.1      *    *   *
webob1.0                       *
webob1.2       *        *      * 

I've asked rbean about consolidating some of these in Fedora at least.

Clearing needinfo, I got response from Luke Macken:
