gproperty: Clean up default value implementation
An overhaul of the default value implementation for GProperty.
Instead of using a separate GValue pointer we can use a slot inside the
GParamSpec qdata member, using a generalized lock quark as the unique
property id. The id is created on demand, so properties with no default
and no locking do not pay any penalty.
The API for setting and overriding the default required some changes:
now it is not necessary to call g_property_set_default() and pass the
class type â though overriding requires calling the newly added
g_property_override_default() and passing the GType used as the key
to retrieve the default.
These changes allow us to drop the GValue* member in the GProperty
structure; we can also reuse the GParamSpec value_type field to drop
both the gtype and prerequisite members of GProperty, thus making
GProperty smaller that 60 bytes on 32bit archs â well within the first
cacheline. This should improve memory usage and caching:
struct _GProperty {
GParamSpec parent_instance; /* 0 40 */
guint flags:15; /* 40:17 4 */
guint is_installed:1; /* 40:16 4 */
/* Bitfield combined with next fields */
guint16 type_size; /* 42 2 */
guint16 priv_offset; /* 44 2 */
guint16 field_offset; /* 46 2 */
GQuark prop_id; /* 48 4 */
GPropertyLockFunc lock_func; /* 52 4 */
GPropertyUnlockFunc unlock_func; /* 56 4 */
/* size: 60, cachelines: 1, members: 9 */
/* last cacheline: 60 bytes */
};
As a bonus, this commit adds support for generic pointer properties.
