2013-09-19coroutine: fix /perf/nesting coroutine benchmarkGabriel Kerneis
The /perf/nesting benchmark is broken because the counters are not reset after each iteration. Therefore, nesting is done only on the first iteration, and skipped on every other. This patch fixes the issue, and reduces the number of iterations to make it possible to run the benchmark in a reasonable amount of time.

2013-09-13qemu-iotests: Fix test 038Max Reitz
Test 038 uses asynchronous I/O, resulting (potentially) in a different output for every run (regarding the order of the I/O accesses). This can be fixed by simply sorting the I/O access messages, since their order is irrelevant anyway (for this asynchonous I/O).

2013-09-12qemu-iotests: Adjustments due to error propagationMax Reitz
When opening/creating images, propagating errors instead of immediately emitting them on occurrence results in errors generally being printed on a single line rather than being split up into multiple ones. This in turn requires adjustments to some test results. Also, test 060 used a sed to filter out the test image directory and format by removing everything from the affected line after a certain keyword; this now also removes the error message itself, which can be fixed by using _filter_testdir and _filter_imgfmt. Finally, _make_test_img in common.rc did not filter out the test image directory etc. from stderr. This has been fixed through a redirection of stderr to stdout (which is already done in _check_test_img and _img_info). Signed-off-by: Max Reitz <mreitz@redhat.com>

2013-09-06qemu-iotests: Fixed test case 026Kevin Wolf
The reference output for test case 026 hasn't been updated in a long time and it's one of the "known failing" cases. This patch updates the reference output so that unintentional changes can be reliably detected again. The problem with this test case is that it produces different output depending on whether -nocache is used or not. The solution of this patch is to actually have two different reference outputs. If nnn.out.nocache exists, it is used as the reference output for -nocache; otherwise, nnn.out stays valid for both cases.

2013-08-19aio: stop using .io_flush()Stefan Hajnoczi
Now that aio_poll() users check their termination condition themselves, it is no longer necessary to call .io_flush() handlers. The behavior of aio_poll() changes as follows: 1. .io_flush() is no longer invoked and file descriptors are *always* monitored. Previously returning 0 from .io_flush() would skip this file descriptor. Due to this change it is essential to check that requests are pending before calling qemu_aio_wait(). Failure to do so means we block, for example, waiting for an idle iSCSI socket to become readable when there are no requests. Currently all qemu_aio_wait()/aio_poll() callers check before calling. 2. aio_poll() now returns true if progress was made (BH or fd handlers executed) and false otherwise. Previously it would return true whenever 'busy', which means that .io_flush() returned true. The 'busy' concept no longer exists so just progress is returned. Due to this change we need to update tests/test-aio.c which asserts aio_poll() return values. Note that QEMU doesn't actually rely on these return values so only tests/test-aio.c cares. Note that ctx->notifier, the EventNotifier fd used for aio_notify(), is now handled as a special case. This is a little ugly but maintains aio_poll() semantics, i.e. aio_notify() does not count as 'progress' and aio_poll() avoids blocking when the user has not set any fd handlers yet. Patches after this remove .io_flush() handler code until we can finally drop the io_flush arguments to aio_set_fd_handler() and friends.

This means we need to check the equivalent of the .io_flush() condition *before* calling aio_poll(ctx, true) to avoid deadlock.
