From 4399596b152f6c933a173b0e97ba4e3b6a57458f Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 6 Aug 2018 08:53:38 +0200 Subject: [PATCH] migration-test: Make wait_command() cope with '%' wait_command() passes its argument @command to qtest_qmp_send(). Falls apart if @command contain '%'. Two ways to disarm this trap: suppress interpretation of '%' by passing @command as argument to format string "%s", or fix it by having wait_command() take the variable arguments to go with @command. Do the latter. This is another step towards compile-time format string checking without triggering -Wformat-nonliteral.
