Markus Armbruster 9d55380b5a qapi: Remove null from schema language
We represent the parse tree as OrderedDict.  We fetch optional dict
members with .get().  So far, so good.

We represent null literals as None.  .get() returns None both for
"absent" and for "present, value is the null literal".  Uh-oh.

Test features-if-invalid exposes this bug: "'if': null" is
misinterpreted as absent "if".

We added null to the schema language to "allow [...] an explicit
default value" (commit e53188ada5 "qapi: Allow true, false and null in
schema json", v2.4.0).  Hasn't happened; null is still unused except
as generic invalid value in tests/.

To fix, we'd have to replace .get() by something more careful, or
represent null differently.  Feasible, but we got more and bigger fish
to fry right now.  Remove the null literal from the schema language.
Replace null in tests by another invalid value.

Test features-if-invalid now behaves as it should.

Markus Armbruster cd346bdc46 tests/qapi-schema: Demonstrate misleading optional tag error
Test flat-union-optional-discriminator declares its union tag as
'*switch': 'Enum', and points to it with 'discriminator': '*switch'.
This gets rejected as "discriminator of flat union 'MyUnion' uses
invalid name '*switch'".  Correct; member 'discriminator' doesn't
accept a '*' prefix.

However, this merely tests name validity checking, which we already
cover elsewhere.  More interesting is testing the valid name 'switch'.
This reports "discriminator 'switch' is not a member of base struct
'Base'", which is misleading.

Copy the existing 'discriminator': '*switch' test to
flat-union-discriminator-bad-name, and rewrite its comment.  Change
flat-union-optional-discriminator to test 'discriminator': 'switch',
and mark it FIXME.

Absent flat union branches default to the empty struct (since commit

A union or alternate without branches makes no sense and doesn't work:
it can't be instantiated.  A union or alternate with just one branch
works, but is degenerate.  We accept the former, but reject the
latter.  Weird.  docs/devel/qapi-code-gen.txt doesn't mention the
difference.  It claims an alternate definition is "is similar to a
simple union type".

Markus Armbruster 56a8caff92 qapi: Restrict strings to printable ASCII
RFC 8259 on string contents:

   All Unicode characters may be placed within the quotation marks,
   except for the characters that MUST be escaped: quotation mark,
   reverse solidus, and the control characters (U+0000 through
   U+001F).

The QAPI schema parser accepts both less and more than JSON: it
accepts only ASCII with \u (less), and accepts control characters
other than LF (new line) unescaped.  How it treats unescaped non-ASCII
input differs between Python 2 and Python 3.

Make it accept strictly less: require printable ASCII.  Drop support
for \b, \f, \n, \r, \t.

Markus Armbruster b22e86585b qapi: Drop support for boxed alternate arguments
Commands and events can define their argument type inline (default) or
by referring to another type ('boxed': true, since commit c818408e44
"qapi: Implement boxed types for commands/events", v2.7.0).  The
unboxed inline definition is an (anonymous) struct type.  The boxed
type may be a struct, union, or alternate type.

The latter is problematic: docs/interop/qemu-spec.txt requires the
value of the 'data' key to be a json-object, but any non-degenerate
alternate type has at least one branch that isn't.

Fortunately, we haven't made use of alternates in this context outside
tests/.  Drop support for them.

QAPISchemaAlternateType.is_empty() is now unused.  Drop it, too.

This is so I2C devices can be found in the ACPI namespace.  Currently
that's only IPMI, but devices can be easily added now.

Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.

Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.

Corey Minyard 77cd44b9ec tests:ipmi: Fix IPMI BT tests
The IPMI BT tests had a race condition, if it receive an IPMI command
to enable interrupt, it would write the message to enable interrupts
after it wrote the command response.  So the test code could
receive the command response and issue the next command before the
device handled the interrupt enable command, and thus no interrupt.

So send the message to enable interrupt before the command response.

Also add some sleeps to give qemu time to handle responses, there was
no delay before, and it could result in an invalid timeout.

And re-enable the tests, as hopefully they are fixed now.

Note that I was unable to reproduce this even with the instructions
Peter gave me, but hopefully this fixes the issue.

Philippe Mathieu-Daudé 471c97a693 BootLinuxSshTest: Only run the tests when explicitly requested
Currently the Avocado framework does not distinct the time spent
downloading assets vs. the time spent running a test. With big
assets (like a full VM image) the tests likely fail.

This is a limitation known by the Avocado team.
Until this issue get fixed, do not run this tests automatically.

Tests can still be run setting the AVOCADO_TIMEOUT_EXPECTED
environment variable.

Thomas Huth 976e8c5414 Replace '-machine accel=xyz' with '-accel xyz'
We've got a separate option to configure the accelerator nowadays, which
is shorter to type and the preferred way of specifying an accelerator.
Use it in the source and examples to show that it is the favored option.
(However, do not touch the places yet which also specify other machine
options or multiple accelerators - these are currently still better
handled with one single "-machine" statement instead)

At the moment this test runs on whatever the host arch is.  But it looks
for 'unavailable-features' which is an x86 specific cpu property.  Tag it
to always use qemu-system-x86_64.

Thomas Huth 4ee5f4be4f tests/qemu-iotests/check: Replace "tests" with "iotests" in final status text
When running "make check -j8" or something similar, the iotests are
running in parallel with the other tests. So when they are printing
out "Passed all xx tests" or a similar status message at the end,
it might not be quite clear that this message belongs to the iotests,
since the output might be mixed with the other tests. Thus change the
word "tests" here to "iotests" instead to avoid confusion.

Andrey Shinkevich 8af224d66b iotests: exclude killed processes from running under Valgrind
The Valgrind tool fails to manage its termination in multi-threaded
 processes when they raise the signal SIGKILL. The bug has been reported
 to the Valgrind maintainers and was registered as the bug #409141:
 https://bugs.kde.org/show_bug.cgi?id=409141
 Let's exclude such test cases from running under the Valgrind until a
 new version with the bug fix is released because checking for the
 memory issues is covered by other test cases.

Andrey Shinkevich 036d8cbffd iotests: allow Valgrind checking all QEMU processes
With the '-valgrind' option, let all the QEMU processes be run under
the Valgrind tool. The Valgrind own parameters may be set with its
environment variable VALGRIND_OPTS, e.g.
$ VALGRIND_OPTS="--leak-check=yes" ./check -valgrind <test#>
or they may be listed in the Valgrind checked file ./.valgrindrc or
~/.valgrindrc like
--memcheck:leak-check=no
--memcheck:track-origins=yes
To exclude a specific process from running under the Valgrind, the
corresponding environment variable VALGRIND_QEMU_<name> is to be set
to the empty string:
$ VALGRIND_QEMU_IO= ./check -valgrind <test#>
When QEMU-IO process is being killed, the shell report refers to the
text of the command in _qemu_io_wrapper(), which was modified with this
patch. So, the benchmark output for the tests 039, 061 and 137 is to be
changed also.

Daniel P. Berrangé bf9e0313c2 tests: make filemonitor test more robust to event ordering
The ordering of events that are emitted during the rmdir
test have changed with kernel >= 5.3. Semantically both
new & old orderings are correct, so we must be able to
cope with either.

To cope with this, when we see an unexpected event, we
push it back onto the queue and look and the subsequent
event to see if that matches instead.

Cleber Rosa 93bbbdf672 Fedora images: use URLs from stable "archives.fedoraproject.org"
The LinuxInitrd.test_with_2gib_file_should_work_with_linux_v4_16 test,
from tests/acceptance/linux_initrd.py, is currently failing to fetch
the "vmlinuz" file.  The reason for the failure is that the Fedora
project retires older versions from the "dl.fedoraproject.org" URL,
and keeps them in "archives.fedoraproject.org".  As an added note,
that test uses a Fedora 28 image, because of the specific Linux kernel
version requirements of the test.

For the sake of stability, let's use URLs from the archived and
supposedely ever stable URLs.  The good news is that the currently
supported versions are also hosted on the later.  This change limits
itself to change the URLs, while keeping the fetched files the same
(as can be evidenced by the unchanged hashes).

Documentation and the "vm tests" fedora definition were also updated.

Alex Bennée 50d2dcaddb tests/docker: --disable-libssh on ubuntu1804 builds
Currently this stops the mega:

  make docker-test-build

from working. Once the source is patched to deal with the case this
workaround can be removed.
