Subject: [Qemu-devel] [PULL 01/18] qemu-iotests/109: Fix lock race condition
Date: Tue,  8 Aug 2017 15:58:21 +0200	[thread overview]
Message-ID: <20170808135838.11525-2-kwolf@redhat.com> (raw)
In-Reply-To: <20170808135838.11525-1-kwolf@redhat.com>

From: Cleber Rosa <crosa@redhat.com>

A race condition is currently present between the clean up attempt of
the QEMU process and the execution of qemu-img.  The actual (bad)
output is:

 -Warning: Image size mismatch!
 -Images are identical.
 +qemu-img: Could not open '<build_dir>/tests/qemu-iotests/scratch/t.raw': Failed to get "consistent read" lock
 +Is another process using the image?

A KILL signal is sent to the QEMU process, but qemu-img may begin to
run before the QEMU process is really gone.  qemu-img will then
attempt to open the TEST_IMG file before it can secure a lock on it.

This attempts a more graceful shutdown, and waits for the QEMU process
to exit.
