From 4b196cd16dcfb17de19a4121f12aa4ef4bf7925f Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 9 Jul 2020 13:02:05 +0200 Subject: [PATCH] iotests: Simplify _filter_img_create() a bit Not only is it a bit stupid to try to filter multi-line "Formatting" output (because we only need it for a single test, which can easily be amended to no longer need it), it is also problematic when there can be output after a "Formatting" line that we do not want to filter as if it were part of it. So rename _filter_img_create to _do_filter_img_create, let it filter only a single line, and let _filter_img_create loop over all input lines, calling _do_filter_img_create only on those that match /^Formatting/ (basically, what _filter_img_create_in_qmp did already). (And fix 020 to work with that.)
