There are no changes to the generated marshal code.
The visitor code becomes slightly more verbose, but remains

arguably a bug fix: although the visitors are not well
documented, use of an optional member should not be attempted
unless guarded by a prior call to visit_optional(). Works only

This patch reduces the number of push_indent()/pop_indent() pairs

indentation in the python files. It is easier to reason about
generated code if the reader does not have to track how much
spacing will be inserted alongside the code, and moreso when all

were already using in-place indentation).
Arguably, the resulting python may be a bit harder to read with C
code at the same indentation as python; on the other hand, not
having to think about push_indent() is a win, and most decent
editors provide syntax highlighting that makes it easier to
visually distinguish python code from string literals that will
become C code.

Add some testsuite exposure for use of a 'number' as part of

does not accept integers for a 'number' in an alternate even

qapi: Add tests for empty unions
The documentation claims that alternates are useful for
allowing two or more types, although nothing enforces this.
Meanwhile, it is silent on whether empty unions are allowed.
In practice, the generated code will compile, in part because
we have a 'void *data' branch; but attempting to visit such a
type will cause an abort(). While there's no technical reason
that a degenerate union could not be made to work, it's harder
to justify the time spent in chasing known (the current
abort() during visit) and unknown corner cases, than it would
be to just outlaw them. A future patch will probably take the
approach of forbidding them; in the meantime, we can at least
add testsuite coverage to make it obvious where things stand.
In addition to adding tests to expose the problems, we also
need to adjust existing tests that are meant to test something
else, but which could fail for the wrong reason if we reject
degenerate alternates/unions.
Note that empty structs are explicitly supported (for example,
right now they are the only way to specify that one branch of a
flat union adds no additional members), and empty enums are
covered by the testsuite as working (even if they do not seem
to have much use).

qapi: Avoid assertion failure on union 'type' collision
The previous commit added two tests that triggered an assertion
failure. It's fairly straightforward to avoid the failure by
just outright forbidding the collision between a union's tag
values and its discriminator name (including the implicit name
'kind' supplied for simple unions [*]). Ultimately, we'd like
to move the collision detection into QAPISchema*.check(), but
for now it is easier just to enhance the existing checks.
[*] Of course, down the road, we have plans to rename the simple
union tag name to 'type' to match the QMP wire name, but the
idea of the collision will still be present even then.
Technically, we could avoid the collision by naming the C union
members representing each enum value as '_case_value' rather
than 'value'; but until we have an actual qapi client (and not
just our testsuite) that has a legitimate reason to match a
case label to the name of a QMP key and needs the name munging
to satisfy the compiler, it's easier to just reject the qapi
as invalid.

qapi: Test for various name collisions
Expose some weaknesses in the generator: we don't always forbid
the generation of structs that contain multiple members that map
to the same C or QMP name. This has already been marked FIXME in
qapi.py in commit d90675f, but having more tests will make sure
future patches produce desired behavior; and updating existing
patches to better document things doesn't hurt, either. Some of
these collisions are already caught in the old-style parser
checks, but ultimately we want all collisions to be caught in the
new-style QAPISchema*.check() methods.
This patch focuses on C struct members, and does not consider
collisions between commands and events (affecting C function
names), or even collisions between generated C type names with
user type names (for things like automatic FOOList struct
representing array types or FOOKind for an implicit enum).
There are two types of struct collisions we want to catch:
1) Collision between two keys in a JSON object. qapi.py prevents
that within a single struct (see test duplicate-key), but it is
possible to have collisions between a type's members and its
base type's members (existing tests struct-base-clash,
struct-base-clash-deep), and its flat union variant members
(renamed test flat-union-clash-member).
2) Collision between two members of the C struct that is generated
for a given QAPI type:
a) Multiple QAPI names map to the same C name (new test
args-name-clash)
b) A QAPI name maps to a C name that is used for another purpose
(new tests flat-union-clash-branch, struct-base-clash-base,
union-clash-data). We already fixed some such cases in commit
0f61af3e and
1e6c1616, but more remain.
c) Two C names generated for other purposes clash
(updated test alternate-clash, new test union-clash-branches,
union-clash-type, flat-union-clash-type)
Ultimately, if we need to have a flat union where a tag value
clashes with a base member name, we could change the generator to
name the union (using 'foo.u.value' rather than 'foo.value') or
otherwise munge the C name corresponding to tag values. But
unless such a need arises, it will probably be easier to just
forbid these collisions.
Some of these negative tests will be deleted later, and positive
tests added to qapi-schema-test.json in their place, when the
generator code is reworked to avoid particular code generation
collisions in class 2).
[Note that viewing this patch with git rename detection enabled
may see some confusion due to renaming some tests while adding
others, but where the content is similar enough that git picks

qapi: Sort qapi-schema tests
Recent changes to qapi have provided quite a bit of churn in
the makefile, because we are inconsistent on what order test
names appear in, and on whether to re-wrap the list of tests or
just add arbitrary line lengths. Writing the list in a sorted
fashion, one test per line, will make future patches easier
to see what tests are being added or removed by a patch.
Although it is tempting to use $(wildcard qapi-schema/*.json)
for a more compact listing, such an approach would risk picking
up leftover garbage .json files in the directory; so keeping
the list explicit is safer for ensuring reproducible tarballs
and test results.

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit
31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)

PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.
