Subject: [Qemu-devel] [PATCH v5 1/6] iotests: allow Valgrind checking all QEMU processes
Date: Fri, 19 Jul 2019 19:30:11 +0300
Message-ID: <1563553816-148827-2-git-send-email-andrey.shinkevich@virtuozzo.com> (raw)
In-Reply-To: <1563553816-148827-1-git-send-email-andrey.shinkevich@virtuozzo.com>

With the '-valgrind' option, let all the QEMU processes be run under
the Valgrind tool. The Valgrind own parameters may be set with its
environment variable VALGRIND_OPTS, e.g.
VALGRIND_OPTS="--leak-check=yes" ./check -qcow2 -valgrind <test#>
or they may be listed in the Valgrind checked file ./.valgrindrc or
~/.valgrindrc like
--memcheck:leak-check=no
--memcheck:track-origins=yes
When QEMU-IO process is being killed, the shell report refers to the
text of the command in _qemu_io_wrapper(), which was modified with this
patch. So, the benchmark output for the tests 039, 061 and 137 is to be
changed also.
