The fixed path and ports get in the way of running our tests and builds in parallel. Instead of using TESTPATH we use mkdtemp() and instead of a fixed port we allow the kernel to assign one and query it afterwards.

2018-06-18test-bdrv-drain: Add test for node deletionMax Reitz
This patch adds two bdrv-drain tests for what happens if some BDS goes away during the drainage. The basic idea is that you have a parent BDS with some child nodes. Then, you drain one of the children. Because of that, the party who actually owns the parent decides to (A) delete it, or (B) detach all its children from it -- both while the child is still being drained. A real-world case where this can happen is the mirror block job, which may exit if you drain one of its children.

2018-06-18block: Really pause block jobs on drainKevin Wolf
We already requested that block jobs be paused in .bdrv_drained_begin, but no guarantee was made that the job was actually inactive at the point where bdrv_drained_begin() returned. This introduces a new callback BdrvChildRole.bdrv_drained_poll() and uses it to make bdrv_drain_poll() consider block jobs using the node to be drained. For the test case to work as expected, we have to switch from block_job_sleep_ns() to qemu_co_sleep_ns() so that the test job is even considered active and must be waited for when draining the node.

2018-06-18tests/test-bdrv-drain: bdrv_drain_all() works in coroutines nowKevin Wolf
Since we use bdrv_do_drained_begin/end() for bdrv_drain_all_begin/end(), coroutine context is automatically left with a BH, preventing the deadlocks that made bdrv_drain_all*() unsafe in coroutine context. Now that we even removed the old polling code as dead code, it's obvious that it's compatible now. Enable the coroutine test cases for bdrv_drain_all().

bdrv_do_drain_begin/end() implement already everything that bdrv_drain_all_begin/end() need and currently still do manually: Disable external events, call parent drain callbacks, call block driver callbacks. It also does two more things: The first is incrementing bs->quiesce_counter. bdrv_drain_all() already stood out in the test case by behaving different from the other drain variants. Adding this is not only safe, but in fact a bug fix. The second is calling bdrv_drain_recurse(). We already do that later in the same function in a loop, so basically doing an early first iteration doesn't hurt.

2018-06-18test-bdrv-drain: bdrv_drain() works with cross-AioContext eventsKevin Wolf
As long as nobody keeps the other I/O thread from working, there is no reason why bdrv_drain() wouldn't work with cross-AioContext events. The key is that the root request we're waiting for is in the AioContext we're polling (which it always is for bdrv_drain()) so that aio_poll() is woken up in the end. Add a test case that shows that it works. Remove the comment in bdrv_drain() that claims otherwise. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-06-15Acceptance tests: add Linux kernel boot and console checking testCleber Rosa
This test boots a Linux kernel, and checks that the given command line was effective in two ways: * It makes the kernel use the set "console device" as a console * The kernel records the command line as expected in the console Given that way too many error conditions may occur, and detecting the kernel boot progress status may not be trivial, this test relies on a timeout to handle unexpected situations. Also, it's *not* tagged as a quick test for obvious reasons. It may be useful, while interactively running/debugging this test, or tests similar to this one, to show some of the logging channels.

2018-06-15block: Fix -blockdev / blockdev-add for empty objects and arraysMarkus Armbruster
-blockdev and blockdev-add silently ignore empty objects and arrays in their argument. That's because qmp_blockdev_add() converts the argument to a flat QDict, and qdict_flatten() eats empty QDict and QList members. For instance, we ignore an empty BlockdevOptions member @cache. No real harm, as absent means the same as empty there. Thus, the flaw puts an artificial restriction on the QAPI schema: we can't have potentially empty objects and arrays within BlockdevOptions, except when they're optional and "empty" has the same meaning as "absent". Our QAPI schema satisfies this restriction (I checked), but it's a trap for the unwary, and a temptation to employ awkward workarounds for the wary. Let's get rid of it. Change qdict_flatten() and qdict_crumple() to treat empty dictionaries and lists exactly like scalars.
