John Snow 9c73517ca5 ide-test: fix timeouts
Use explicit timeouts instead of trying to approximate it by counting
the cumulative duration of nsleep calls.

In practice, the timeout if inb() dwarfed the nsleep delays, and as a
result the real timeout value became a lot larger than 5 seconds.

So: change the semantics from "Not sooner than 5 seconds" to "no more
than 5 seconds" to ensure we don't hang the tester for very long.

One test case closed an event notifier (event_notifier_cleanup())
without first disabling it (set_event_notifier(..., NULL)). This
resulted in a leftover handle 0 that was added to each subsequent
WaitForMultipleObjects() call, causing the function to fail (invalid
handle).

Markus Armbruster 1d649244b3 ivshmem: Rename property memdev to x-memdev for 2.5
The device's guest interface and its QEMU user interface are
flawed^Whotly debated.  We'll resolve that in the next development
cycle, probably by deprecating the device in favour of a cleaned up,
but not quite compatible revision.

To avoid adding more baggage to the soon-to-be-deprecated interface,
mark property "memdev" as experimental, by renaming it to "x-memdev".
It's the only recent user interface change.

John Snow a421f3c385 ide-test: cdrom_pio_impl fixup
Final tidying: move the interrupt wait into the loop,
document that the status read clears the IRQ, and move
the final interrupt check outside of the loop.

This should be functionally equivalent to how it works
currently, but a little less ambiguous and slightly more
explicit about the state transitions.

The check for the cleared BSY flag has to be performed

Commit 5f81724d revealed this glitch as the BSY flag

While at it fix the descriptions and add a comment before
the nested for loop that transfers the data.

Marc-André Lureau 421f4448ce tests: re-enable vhost-user-test
Commit 7fe34ca9c2 actually disabled vhost-user-test altogether,
since CONFIG_VHOST_NET is a per-target config variable.

tests/vhost-user-test is already x86/x64 softmmu specific test, in order
to enable it correctly, kvm & vhost-net are also conditions. To check
that, set CONFIG_VHOST_NET_TEST_$target when kvm is also enabled.

Since "check-qtest-x86_64-y = $(check-qtest-i386-y)", avoid duplication
when both x86 & x64 are enabled.

Other targets than x86 aren't enabled yet, and is intentionally left as
a future improvement, since I can't easily test those.

Daniel P. Berrange 8c4d156c18 qom: Add a test case for complex property finalization
Devices have some quite complex object child/link relationships
which place some requirements on the object_property_del_all()
function to consider that properties can be modified while
being iterated over.

This extends the QOM property test case to replicate the
device like structure and expose any potential bugs in the
object_property_del_all() function.

Daniel P. Berrange a00c948241 qom: Introduce ObjectPropertyIterator struct for iteration
Some users of QOM need to be able to iterate over properties
defined against an object instance. Currently they are just
directly using the QTAIL macros against the object properties
data structure.

This is bad because it exposes them to changes in the data
structure used to store properties, as well as changes in
functionality such as ability to register properties against
the class.

This provides an ObjectPropertyIterator struct which will
insulate the callers from the particular data structure
used to store properties. It can be used thus

  ObjectProperty *prop;
  ObjectPropertyIterator *iter;

  iter = object_property_iter_init(obj);
  while ((prop = object_property_iter_next(iter))) {
      ... do something with prop ...
  }
  object_property_iter_free(iter);

Alberto Garcia bd797fc15b util: Infrastructure for computing recent averages
This module computes the average of a set of values within a time
window, keeping also track of the minimum and maximum values.

In order to produce more accurate results it works internally by
creating two time windows of the same period, offsetted by half of
that period. Values are accounted on both windows and the data is
always returned from the oldest one.

[Add missing util/replay.o to test-timed-average dependencies to fix the
build.

Commit 934659c switched the iotests to run qemu-io from a bash subshell,
in order to catch segfaults.  This method is incompatible with the
current valgrind_qemu_io() bash function.

Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is passed back to the
caller.

Update test output for tests 039, 061, and 137 as it looks for the

Jeff Cody f6c8c2e055 qemu-iotests: fix cleanup of background processes
Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults.  Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
after executing iotests.

Since the process is using exec in the subshell, the PID is the
same as the subshell PID.

Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only
track the qemu PID, however, if requested - not all usage requires
killing the process.

Our testsuite had no coverage of empty arrays, nor of what
happens when the input does not match the expected type.
Useful to have, especially if we start changing the visitor
contracts.

I did not think it worth duplicating these additions to
test-qmp-input-strict; since all strict mode does is add
the ability to reject JSON input that has more keys than
what the visitor expects, yet the additions in this patch
error out earlier than that point regardless of whether
strict mode was requested.

Our generated list visitors have the same problem as has been
mentioned elsewhere (see commit 2f52e20): they allocate data
even on failure. An upcoming patch will correct things to
provide saner guarantees, but first we need to expose the
behavior in the testsuite to ensure we aren't introducing any
memory usage bugs.

There are more test cases throughout the test-qmp-input-* tests
that already deal with partial allocation; a later commit will
clean up all visit_type_FOO(), without marking all of the tests
with FIXME at this time.

Eric Blake a12a5a1a01 qapi: Simplify error cleanup in test-qmp-*
We have several tests that perform multiple sub-actions that are
expected to fail.  Asserting that an error occurred, then clearing
it up to prepare for the next action, turned into enough
boilerplate that it was sometimes forgotten (for example, a number
of tests added to test-qmp-input-visitor.c in d88f5fd leaked err).
Worse, if an error is not reset to NULL, we risk invalidating
later use of that error (passing a non-NULL err into a function
is generally a bad idea).  Encapsulate the boilerplate into a
single helper function error_free_or_abort(), and consistently
use it.

The new function is added into error.c for use everywhere,
although it is anticipated that testsuites will be the main
client.

Eric Blake 3f66f764ee qapi: Simplify non-error testing in test-qmp-*
By using &error_abort, we can avoid a local err variable in
situations where we expect success.  It also has the nice
effect that if the test breaks, the error message from
error_abort tends to be nicer than that of g_assert().

This patch has an additional bonus of fixing several call sites that
were passing &err to two different functions without checking it in
between.  In general that is unsafe practice; because if the first
function sets an error, the second function could abort() if it tries to
set a different error. We got away with it because we were asserting
that err was NULL through the entire chain, but switching to
&error_abort avoids the questionable practice up front.

Eric Blake b18f1141d0 qapi: Plug leaks in test-qmp-*
Make valgrind happy with the current state of the tests, so that
it is easier to see if future patches introduce new memory problems
without being drowned in noise.  Many of the leaks were due to
calling a second init without tearing down the data from an earlier
visit.  But since teardown is already idempotent, and we already
register teardown as part of input_visitor_test_add(), it is nicer
to just make init() safe to call multiple times than it is to have
to make all tests call teardown.

Another common leak was forgetting to clean up an error object,
after testing that an error was raised.

Another leak was in test_visitor_in_struct_nested(), failing to
clean the base member of UserDefTwo.  Cleaning that up left
check_and_free_str() as dead code (since using the qapi_free_*
takes care of recursion, and we don't want double frees).

A final leak was in test_visitor_out_any(), which was reassigning
the qobj local variable to a subset of the overall structure
needing freeing; it did not result in a use-after-free, but
was not cleaning up all the qdict.

test-qmp-event and test-qmp-commands were already clean.

Eric Blake 0920a17199 qapi: Share test_init code in test-qmp-input*
Rather than duplicate the body of two functions just to
decide between qobject_from_jsonv() and qobject_from_json(),
exploit the fact that qobject_from_jsonv() intentionally
takes 'va_list *' instead of the more common 'va_list', and
that qobject_from_json() just calls qobject_from_jsonv(,NULL).
For each file, our two existing init functions then become
thin wrappers around a new internal function, and future
updates to initialization don't have to be duplicated.
