From: Victor Stinner Date: Fri, 12 Jun 2015 13:21:09 +0000 (+0200) Subject: Replace dit.itervalues() with dict.values() X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=3fabed9d64696a204263fd7e00b65115a8ecce87;p=openstack-build%2Fcinder-build.git Replace dit.itervalues() with dict.values() This change adds Python 3 compatibility to the modified code. The itervalues() method of Python 2 dictionaries was renamed to values() on Python 3. As discussed on the openstack-dev mailing list, itervalues() must be replaced with values(), six.itervalues() should not be used. In OpenStack, the overhead of creating a temporary list with dict.values() on Python 2 is negligible.
