Pretty printing of JSON responses is important to be able to understand large responses from query commands in particular, eg
(QEMU) query-chardev { u'return': [ { u'filename': u'vc', u'frontend-open': False, u'label': u'parallel0'}, { u'filename': u'vc', u'frontend-open': True, u'label': u'serial0'}, { u'filename': u'unix:/tmp/qemp,server', u'frontend-open': True, u'label': u'compat_monitor0'}]} Unfortunately this was broken during the addition of the verbose flag in commit 1ceca07e48ead0dd2e41576c81d40e6a91cafefd Author: John Snow <js...@redhat.com> Date: Wed Apr 29 15:14:04 2015 -0400 scripts: qmp-shell: Add verbose flag This is because that change turned the python data structure into a formatted JSON string before the pretty print was given it. So we're just pretty printing a string, which is a no-op. This fixes pretty printing of the command responses and as an added benefit it will also pretty print command arguments in verbose mode (QEMU) object-add qom-type=secret id=sec0 props={"data":"123456"} { 'arguments': { 'id': 'sec0', 'props': { u'data': u'123456'}, 'qom-type': 'secret'}, 'execute': 'object-add'} { u'return': { }} Signed-off-by: Daniel P.
