Subject: [PATCH 017/163] iotests: Unify log outputs between Python 2 and 3

RH-Author: John Snow <jsnow@redhat.com>

O-Subject: [RHEL-7.7 qemu-kvm-rhev PATCH 03/19] iotests: Unify log outputs between Python 2 and 3
Bugzilla: 1668956
RH-Acked-by: Eduardo Habkost <ehabkost@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>

From: Max Reitz <mreitz@redhat.com>

When dumping an object into the log, there are differences between
Python 2 and 3.  First, unicode strings are prefixed by 'u' in Python 2
(they are no longer in 3, because unicode strings are the default
there).  Second, the order of keys in dicts may differ.  Third,
especially long numbers are longs in Python 2 and thus get an 'L'
suffix, which does not happen in Python 3.

We can get around all of these differences by dumping objects (lists and
dicts) in a language-independent format, namely JSON.  The JSON
generator even allows emitting dicts with their keys sorted
alphabetically.

This changes the output of all tests that use these logging functions
(dict keys are ordered now, strings in dicts are now enclosed in double
quotes instead of single quotes, the 'L' suffix of large integers is
dropped, and "true" and "false" are now in lower case).
The quote change necessitates a small change to a filter used in test
207.
