From 613ea1552bdffe9d3d913df26922a4edb4afa56d Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Mon, 15 Jan 2018 17:02:31 +0000 Subject: [PATCH] qapi: use items()/values() intead of iteritems()/itervalues() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The iteritems()/itervalues() methods are gone in py3, but the items()/values() methods are still around. The latter are less efficient than the former in py2, but this has unmeasurably small impact on QEMU build time, so taking portability over efficiency is a net win.
