When creating new QOM types, there is a lot of boilerplate code that
must be repeated using a standard pattern. This is tedious to write
and liable to suffer from subtle inconsistencies. Thus it would
benefit from some simple automation.
QOM was loosely inspired by GLib's GObject, and indeed GObject suffers
from the same burden of boilerplate code, but has long provided a set of
macros to eliminate this burden in the source implementation. More
recently it has also provided a set of macros to eliminate this burden
in the header declaration.
In GLib there are the G_DECLARE_* and G_DEFINE_* family of macros
for the header declaration and source implementation respectively:
https://developer.gnome.org/gobject/stable/chapter-gobject.htmlhttps://developer.gnome.org/gobject/stable/howto-gobject.html
This patch takes inspiration from GObject to provide the equivalent
functionality for QOM.
In the header file, instead of:
typedef struct MyDevice MyDevice;
typedef struct MyDeviceClass MyDeviceClass;
G_DEFINE_AUTOPTR_CLEANUP_FUNC(MyDeviceClass, object_unref)
#define MY_DEVICE_GET_CLASS(void *obj) \
OBJECT_GET_CLASS(MyDeviceClass, obj, TYPE_MY_DEVICE)
#define MY_DEVICE_CLASS(void *klass) \
OBJECT_CLASS_CHECK(MyDeviceClass, klass, TYPE_MY_DEVICE)
#define MY_DEVICE(void *obj)
OBJECT_CHECK(MyDevice, obj, TYPE_MY_DEVICE)
struct MyDeviceClass {
DeviceClass parent_class;
};
We now have
OBJECT_DECLARE_SIMPLE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
In cases where the class needs some virtual methods, it can be left
to be implemented manually using
OBJECT_DECLARE_TYPE(MyDevice, my_device, MY_DEVICE)
Note that these macros are including support for g_autoptr() for the
object types, which is something previously only supported for variables
declared as the base Object * type.
Meanwhile in the source file, instead of:
static void my_device_finalize(Object *obj);
static void my_device_class_init(ObjectClass *oc, void *data);
static void my_device_init(Object *obj);
static const TypeInfo my_device_info = {
.parent = TYPE_DEVICE,
.name = TYPE_MY_DEVICE,
.instance_size = sizeof(MyDevice),
.instance_init = my_device_init,
.instance_finalize = my_device_finalize,
.class_size = sizeof(MyDeviceClass),
.class_init = my_device_class_init,
};
static void
my_device_register_types(void)
{
type_register_static(&my_device_info);
}
type_init(my_device_register_types);
We now have
OBJECT_DEFINE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
Or, if a class needs to implement interfaces:
OBJECT_DEFINE_TYPE_WITH_INTERFACES(MyDevice, my_device, MY_DEVICE, DEVICE,
{ TYPE_USER_CREATABLE }, { NULL })
Or, if a class needs to be abstract
OBJECT_DEFINE_ABSTRACT_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
IOW, in both cases the maintainer now only has to think about the
interesting part of the code which implements useful functionality
and avoids much of the boilerplate.

The object_ref/unref methods are intended for use with any subclass of
the base Object. Using "Object *" in the signature is not adding any
meaningful level of type safety, since callers simply use "OBJECT(ptr)"
and this expands to an unchecked cast "(Object *)".
By using "void *" we enable the object_unref() method to be used to
provide support for g_autoptr() with any subclass.

Ever since commit 537fe2d63f there
has been a 'linkage' to sdl for compiling baum.c. Originally it
had to do with including sdl cflags for any file including sdl
headers. There is no longer any such need for baum.c, but the
association has persisted in the make system, and with the switch
to meson it has now become a hard requirement, which now causes
chardev-baum.so to not be produced if sdl is not configured.

not propagate dependencies correctly from static libraries, for example.

Whenever a test appears in multiple suites, the rules generated

will be added to the prerequisites just once.
This has other advantages: it removes the handling of -k and
it increases parallelism.
