+Ordering finalizers in the MiniMark GC
+======================================
-Ordering finalizers in the SemiSpace GC
-=======================================
+RPython interface
+-----------------
-Goal
-----
+In RPython programs like PyPy, we need a fine-grained method of
+controlling the RPython- as well as the app-level ``__del__()``. To
+make it possible, the RPython interface is now the following one (from
+May 2016):
-After a collection, the SemiSpace GC should call the finalizers on
+* RPython objects can have ``__del__()``. These are called
+ immediately by the GC when the last reference to the object goes
+ away, like in CPython. However, the long-term goal is that all
+ ``__del__()`` methods should only contain simple enough code. If
+ they do, we call them "destructors". They can't use operations that
+ would resurrect the object, for example. Use the decorator
+ ``@rgc.must_be_light_finalizer`` to ensure they are destructors.
+
+* RPython-level ``__del__()`` that are not passing the destructor test
+ are supported for backward compatibility, but deprecated. The rest
+ of this document assumes that ``__del__()`` are all destructors.
+
+* For any more advanced usage --- in particular for any app-level
+ object with a __del__ --- we don't use the RPython-level
+ ``__del__()`` method. Instead we use
+ ``rgc.FinalizerController.register_finalizer()``. This allows us to
+ attach a finalizer method to the object, giving more control over
+ the ordering than just an RPython ``__del__()``.
+
+We try to consistently call ``__del__()`` a destructor, to distinguish
+it from a finalizer. A finalizer runs earlier, and in topological
+order; care must be taken that the object might still be reachable at
+this point if we're clever enough. A destructor on the other hand runs
+last; nothing can be done with the object any more, and the GC frees it
+immediately.
+
+
+Destructors
+-----------
+
+A destructor is an RPython ``__del__()`` method that is called directly
+by the GC when it is about to free the memory. Intended for objects
+that just need to free an extra block of raw memory.
+
+There are restrictions on the kind of code you can put in ``__del__()``,
+including all other functions called by it. These restrictions are
+checked. In particular you cannot access fields containing GC objects.
+Right now you can't call any external C function either.
+
+Destructors are called precisely when the GC frees the memory of the
+object. As long as the object exists (even in some finalizer queue or
+anywhere), its destructor is not called.
+
+
+Register_finalizer
+------------------
+
+The interface for full finalizers is made with PyPy in mind, but should
+be generally useful.
+
+The idea is that you subclass the ``rgc.FinalizerQueue`` class::
+
+* You must give a class-level attribute ``base_class``, which is the
+ base class of all instances with a finalizer. (If you need
+ finalizers on several unrelated classes, you need several unrelated
+ ``FinalizerQueue`` subclasses.)
+
+* You override the ``finalizer_trigger()`` method; see below.
+
+Then you create one global (or space-specific) instance of this
+subclass; call it ``fin``. At runtime, you call
+``fin.register_finalizer(obj)`` for every instance ``obj`` that needs
+a finalizer. Each ``obj`` must be an instance of ``fin.base_class``,
+but not every such instance needs to have a finalizer registered;
+typically we try to register a finalizer on as few objects as possible
+(e.g. only if it is an object which has an app-level ``__del__()``
+method).
+
+After a major collection, the GC finds all objects ``obj`` on which a
+finalizer was registered and which are unreachable, and mark them as
+reachable again, as well as all objects they depend on. It then picks
+a topological ordering (breaking cycles randomly, if any) and enqueues
+the objects and their registered finalizer functions in that order, in
+a queue specific to the prebuilt ``fin`` instance. Finally, when the
+major collection is done, it calls ``fin.finalizer_trigger()``.
+
+This method ``finalizer_trigger()`` can either do some work directly,
+or delay it to be done later (e.g. between two bytecodes). If it does
+work directly, note that it cannot (directly or indirectly) cause the
+GIL to be released.
+
+To find the queued items, call ``fin.next_dead()`` repeatedly. It
+returns the next queued item, or ``None`` when the queue is empty.
+
+In theory, it would kind of work if you cumulate several different
+``FinalizerQueue`` instances for objects of the same class, and
+(always in theory) the same ``obj`` could be registered several times
+in the same queue, or in several queues. This is not tested though.
+For now the untranslated emulation does not support registering the
+same object several times.
