qapi: Unbox base members
Rather than storing a base class as a pointer to a box, just
store the fields of that base class in the same order, so that
a child struct can be directly cast to its parent. This gives
less malloc overhead, less pointer dereferencing, and even less
generated code. Compare to the earlier commit 1e6c1616a "qapi:
Generate a nicer struct for flat unions" (although that patch
had fewer places to change, as less of qemu was directly using
qapi structs for flat unions). It also allows us to turn on
automatic type-safe wrappers for upcasting to the base class
of a struct.
Changes to the generated code look like this in qapi-types.h:
| struct SpiceChannel {
|- SpiceBasicInfo *base;
|+ /* Members inherited from SpiceBasicInfo: */
|+ char *host;
|+ char *port;
|+ NetworkAddressFamily family;
|+ /* Own members: */
| int64_t connection_id;
as well as additional upcast functions like qapi_SpiceChannel_base().
Meanwhile, changes to qapi-visit.c look like:
| static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp)
| {
| Error *err = NULL;
|
|- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err);
|+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err);
| if (err) {
(the cast is necessary, since our upcast wrappers only deal with a
single pointer, not pointer-to-pointer); plus the wholesale
elimination of some now-unused visit_type_implicit_FOO() functions.
Without boxing, the corner case of one empty struct having
another empty struct as its base type now requires inserting a
dummy member (previously, the 'Base *base' member sufficed).
And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

qapi: Drop tests for inline nested structs
A future patch will be using a 'name':{dictionary} entry in the
QAPI schema to specify a default value for an optional argument;
but existing use of inline nested structs conflicts with that goal.
More precisely, a definition in the QAPI schema associates a name
with a set of properties:
Example 1: { 'struct': 'Foo', 'data': { MEMBERS... } }
associates the global name 'Foo' with properties (meta-type struct)
and MEMBERS...
Example 2: 'mumble': TYPE
within MEMBERS... above associates 'mumble' with properties (type
TYPE) and (optional false) within type Foo
The syntax of example 1 is extensible; if we need another property,
we add another name/value pair to the dictionary (such as
'base':TYPE). The syntax of example 2 is not extensible, because
the right hand side can only be a type.
We have used name encoding to add a property: "'*mumble': 'int'"
associates 'mumble' with (type int) and (optional true). Nice,
but doesn't scale. So the solution is to change our existing uses
to be syntactic sugar to an extensible form:
NAME: TYPE --> NAME: { 'type': TYPE, 'optional': false }
*ONAME: TYPE --> ONAME: { 'type': TYPE, 'optional': true }
This patch fixes the testsuite to avoid inline nested types, by
breaking the nesting into explicit types; it means that the type
is now boxed instead of unboxed in C code, but makes no difference
on the wire (and if desired, a later patch could change the
generator to not do so much boxing in C). When touching code to
add new allocations, also convert existing allocations to
consistently prefer typesafe g_new0 over g_malloc0 when a type
name is involved.

qapi: Don't special-case simple union wrappers
Simple unions were carrying a special case that hid their 'data'
QMP member from the resulting C struct, via the hack method
QAPISchemaObjectTypeVariant.simple_union_type(). But by using
the work we started by unboxing flat union and alternate
branches, coupled with the ability to visit the members of an
implicit type, we can now expose the simple union's implicit
type in qapi-types.h:
| struct q_obj_ImageInfoSpecificQCow2_wrapper {
| ImageInfoSpecificQCow2 *data;
| };
|
| struct q_obj_ImageInfoSpecificVmdk_wrapper {
| ImageInfoSpecificVmdk *data;
| };
...
| struct ImageInfoSpecific {
| ImageInfoSpecificKind type;
| union { /* union tag is @type */
| void *data;
|- ImageInfoSpecificQCow2 *qcow2;
|- ImageInfoSpecificVmdk *vmdk;
|+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2;
|+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk;
| } u;
| };
Doing this removes asymmetry between QAPI's QMP side and its
C side (both sides now expose 'data'), and means that the
treatment of a simple union as sugar for a flat union is now
equivalent in both languages (previously the two approaches used
a different layer of dereferencing, where the simple union could
be converted to a flat union with equivalent C layout but
different {} on the wire, or to an equivalent QMP wire form
but with different C representation). Using the implicit type
also lets us get rid of the simple_union_type() hack.
Of course, now all clients of simple unions have to adjust from
using su->u.member to using su->u.member.data; while this touches
a number of files in the tree, some earlier cleanup patches
helped minimize the change to the initialization of a temporary
variable rather than every single member access. The generated
qapi-visit.c code is also affected by the layout change:

qapi: check invalid arguments on no-args commands
The generated marshal functions do not visit arguments from commands
that take no arguments. Thus they fail to catch invalid
members. Visit the arguments, if provided, to throw an error in case of
invalid members.
Currently, qmp_check_client_args() checks for invalid arguments and
correctly catches this case. When switching to qmp_dispatch() we want to
keep that behaviour. The commands using 'O' may have arbitrary
arguments, and must have 'gen': false in the qapi schema to skip the
generated checks.
Old/new diff:
void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp)
{
Error *err = NULL;
+ Visitor *v = NULL;
- (void)args;
+ if (args) {
+ v = qmp_input_visitor_new(QOBJECT(args), true);
+ visit_start_struct(v, NULL, NULL, 0, &err);
+ if (err) {
+ goto out;
+ }
+
+ if (!err) {
+ visit_check_struct(v, &err);
+ }
+ visit_end_struct(v, NULL);
+ if (err) {
+ goto out;
+ }
+ }
qmp_stop(&err);
+
+out:
error_propagate(errp, err);
+ visit_free(v);
+ if (args) {
+ v = qapi_dealloc_visitor_new();
+ visit_start_struct(v, NULL, NULL, 0, NULL);
+
+ visit_end_struct(v, NULL);
+ visit_free(v);
+ }
}
The new code closely resembles code for a command with arguments.
Differences:
- the visit of the argument and its cleanup struct don't visit any
members (because there are none).
- the visit of the argument struct and its cleanup are conditional.

qapi: check invalid arguments on no-args commands
The generated marshal functions do not visit arguments from commands
that take no arguments. Thus they fail to catch invalid
members. Visit the arguments, if provided, to throw an error in case of
invalid members.
Currently, qmp_check_client_args() checks for invalid arguments and
correctly catches this case. When switching to qmp_dispatch() we want to
keep that behaviour. The commands using 'O' may have arbitrary
arguments, and must have 'gen': false in the qapi schema to skip the
generated checks.
Old/new diff:
void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp)
{
Error *err = NULL;
+ Visitor *v = NULL;
- (void)args;
+ if (args) {
+ v = qmp_input_visitor_new(QOBJECT(args), true);
+ visit_start_struct(v, NULL, NULL, 0, &err);
+ if (err) {
+ goto out;
+ }
+
+ if (!err) {
+ visit_check_struct(v, &err);
+ }
+ visit_end_struct(v, NULL);
+ if (err) {
+ goto out;
+ }
+ }
qmp_stop(&err);
+
+out:
error_propagate(errp, err);
+ visit_free(v);
+ if (args) {
+ v = qapi_dealloc_visitor_new();
+ visit_start_struct(v, NULL, NULL, 0, NULL);
+
+ visit_end_struct(v, NULL);
+ visit_free(v);
+ }
}
The new code closely resembles code for a command with arguments.
Differences:
- the visit of the argument and its cleanup struct don't visit any
members (because there are none).
- the visit of the argument struct and its cleanup are conditional.

qapi: Unbox base members
Rather than storing a base class as a pointer to a box, just
store the fields of that base class in the same order, so that
a child struct can be directly cast to its parent. This gives
less malloc overhead, less pointer dereferencing, and even less
generated code. Compare to the earlier commit 1e6c1616a "qapi:
Generate a nicer struct for flat unions" (although that patch
had fewer places to change, as less of qemu was directly using
qapi structs for flat unions). It also allows us to turn on
automatic type-safe wrappers for upcasting to the base class
of a struct.
Changes to the generated code look like this in qapi-types.h:
| struct SpiceChannel {
|- SpiceBasicInfo *base;
|+ /* Members inherited from SpiceBasicInfo: */
|+ char *host;
|+ char *port;
|+ NetworkAddressFamily family;
|+ /* Own members: */
| int64_t connection_id;
as well as additional upcast functions like qapi_SpiceChannel_base().
Meanwhile, changes to qapi-visit.c look like:
| static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp)
| {
| Error *err = NULL;
|
|- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err);
|+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err);
| if (err) {
(the cast is necessary, since our upcast wrappers only deal with a
single pointer, not pointer-to-pointer); plus the wholesale
elimination of some now-unused visit_type_implicit_FOO() functions.
Without boxing, the corner case of one empty struct having
another empty struct as its base type now requires inserting a
dummy member (previously, the 'Base *base' member sufficed).
And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

qmp-input-visitor: Favor new visit_free() function
Now that we have a polymorphic visit_free(), we no longer need
qmp_input_visitor_cleanup(); which in turn means we no longer
need to return a subtype from qmp_input_visitor_new() nor a
public upcast function.
Generated code changes to qmp-marshal.c look like:
