From 55cd64eab5cb7958c629edbf5f2233b87dfbd1b0 Mon Sep 17 00:00:00 2001 From: John Snow Date: Fri, 21 Dec 2018 04:35:28 -0500 Subject: iotests: implement pretty-print for log and qmp_log If iotests have lines exceeding >998 characters long, git doesn't want to send it plaintext to the list. We can solve this by allowing the iotests to use pretty printed QMP output that we can match against instead. As a bonus, it's much nicer for human eyes too.
