2013-12-23i440fx-test: give each GTest case its own qtestLaszlo Ersek1-13/+19
The current two GTest cases, /i440fx/defaults and /i440fx/pam can share a qemu process, but the next two cases will need dedicated instances. It is messy (and order-dependent) to dynamically configure GTest cases one by one to start, stop, or keep the current qtest (*); let's just have each GTest work with its own qtest. The performance difference should be negligible. (*) As g_test_run() can be invoked at most once per process startup, and it runs GTest cases in sequence, we'd need clumsy data structures to control each GTest case to start/stop/keep the qemu instance. Or, we'd have to code the same information into the test methods themselves, which would make them even more order-dependent. Signed-off-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Michael S.

2013-12-06qemu-iotests: filter QEMU monitor \r\nStefan Hajnoczi2-57/+58
SMTP does not preserve newlines. This is normally not a problem if the email body uses DOS or UNIX newlines consistently. In 051.out we mix UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n). This patch filters the QEMU monitor output so the golden master file uses UNIX newlines exclusively. The result is that patches touching 051.out will apply cleanly without mangling newlines after this commit. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-12-06aio: make aio_poll(ctx, true) block with no fdsStefan Hajnoczi1-1/+0
This patch drops a special case where aio_poll(ctx, true) returns false instead of blocking if no file descriptors are waiting on I/O. Now it is possible to block in aio_poll() to wait for aio_notify(). This change eliminates busy waiting. bdrv_drain_all() used to rely on busy waiting to completed throttled I/O requests but this is no longer required so we can simplify aio_poll(). Note that aio_poll() still returns false when aio_notify() was used. In other words, stopping a blocking aio_poll() wait is not considered making progress. Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx, true) would immediately return false instead of blocking.
