Now we have the following behavior:1) object_new() returns an object with ref = 1 2) object_initialize() does not increase the reference count (ref may be 0). 3) object_deref() will finalize the object when ref = 0. it does not free the memory associated with the object. 4) both link and child properties correctly set the reference count. The expected usage is the following: 1) child devices should generally be created via object_initialize() using memory from the parent device. Adding the object as a child property will take ownership of the object and tie the child's life cycle to the parent. 2) If a child device is created via qdev_create() or some other form of object_new(), there must be an object_delete() call in the parent device's finalize function.
We might want to fix this by adding a special "created as child" refcount value, so that the object_delete can still be automatic. Adding floating references as they have them in GObject is also possible. I agree that it can be left for later, though.
