Subject: [Qemu-devel] [PATCH v7 2/3] iotests: Improve image-clear tests on non-aligned image
Date: Thu, 30 Mar 2017 17:36:44 -0500	[thread overview]
Message-ID: <20170330223645.349-3-eblake@redhat.com> (raw)
In-Reply-To: <20170330223645.349-1-eblake@redhat.com>

Tweak 097 and 176 to operate on an image that is not cluster-aligned,
to give further coverage of clearing out an entire image.

Tested for qcow (97) and qcow2 (97 and 176).

The fact that there is a subtle difference between the expected
outputs of 97 and 176 on pass 0 is evidence that we still don't
always clear out the full image in qcow2.  Commit a3e1505 fixed
the case of clusters stranded at the 2G mark, but did not fix
stranding an unaligned tail.  That will be the next patch, kept
separate to make it easier to see the impact.

Signed-off-by: Eric Blake <eblake@redhat.com>

---
v7: also write data in the unaligned cluster, and document bug it exposes
v6: new patch
