From 08fcd6111e1949f456e1b232ebeeb0cc17019a92 Mon Sep 17 00:00:00 2001 From: John Snow Date: Fri, 21 Dec 2018 04:35:27 -0500 Subject: [PATCH] iotests: change qmp_log filters to expect QMP objects only As laid out in the previous commit's message: ``` Several places in iotests deal with serializing objects into JSON strings, but to add pretty-printing it seems desirable to localize all of those cases. log() seems like a good candidate for that centralized behavior. log() can already serialize json objects, but when it does so, it assumes filters=[] operates on QMP objects, not strings. qmp_log currently operates by dumping outgoing and incoming QMP objects into strings and filtering them assuming that filters=[] are string filters. ``` Therefore: Change qmp_log to treat filters as if they're always qmp object filters, then change the logging call to rely on log()'s ability to serialize QMP objects, so we're not duplicating that effort. Add a qmp version of filter_testfiles and adjust the only caller using it for qmp_log to use the qmp version.
