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.

They can't + use operations that would resurrect the object, for example. + +* 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. + + +Destructors +----------- + +A destructor is an RPython ``__del__()`` method that is called directly +by the GC when there is no more reference to an object.

These restrictions are +checked. In particular you cannot access fields containing GC objects; +and if you call an external C function, it must be a "safe" function +(e.g. not releasing the GIL; use ``releasegil=False`` in +``rffi.llexternal()``). + +If there are several objects with destructors that die during the same +GC cycle, they are called in a completely random order --- but that +should not matter because destructors cannot do much anyway. + + +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.FinalizerController`` class:: + +* You must give a class-level attribute ``base_class``, which is the + base class of all instances with a finalizer.

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).

Helps with +CPython C extension modules that call some PyXxx() functions without +holding the GIL (arguably, they are theorically buggy). diff --git a/pypy/goal/targetpypystandalone.py b/pypy/goal/targetpypystandalone.py --- a/pypy/goal/targetpypystandalone.py +++ b/pypy/goal/targetpypystandalone.py @@ -344,10 +344,6 @@ return PyPyJitPolicy(pypy_hooks) def get_entry_point(self, config): -

	Add rgc.FinalizerQueue, documented in pypy/doc/discussion/finalizer-
	order.rst. It is a more flexible way to make RPython finalizers.

	This branch does not use it in pypy/, it just adds the new way while
	keeping the old one valid too.

-.. XXX armin, what do we do with this?
+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.
+
+
+Destructors
+-----------
+
+A destructor is an RPython ``__del__()`` method that is called directly
+by the GC when there is no more reference to an object.  Intended for
+objects that just need to free a block of raw memory or close a file.
+
+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;
+and if you call an external C function, it must be a "safe" function
+(e.g. not releasing the GIL; use ``releasegil=False`` in
+``rffi.llexternal()``).
+
+If there are several objects with destructors that die during the same
+GC cycle, they are called in a completely random order --- but that
+should not matter because destructors cannot do much anyway.
+
+
+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.
+
+It is allowed in theory to 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.
+
+
+Ordering of finalizers
+----------------------
+
+After a collection, the MiniMark GC should call the finalizers on
 *some* of the objects that have one and that have become unreachable.
 Basically, if there is a reference chain from an object a to an object b
 then it should not call the finalizer for b immediately, but just keep b
 alive and try again to call its finalizer after the next collection.
 
-This basic idea fails when there are cycles.  It's not a good idea to
+(Note that this creates rare but annoying issues as soon as the program
+creates chains of objects with finalizers more quickly than the rate at
+which major collections go (which is very slow).  In August 2013 we tried
+instead to call all finalizers of all objects found unreachable at a major
+collection.  That branch, ``gc-del``, was never merged.  It is still
+unclear what the real consequences would be on programs in the wild.)
+
+The basic idea fails in the presence of cycles.  It's not a good idea to
 keep the objects alive forever or to never call any of the finalizers.
 The model we came up with is that in this case, we could just call the
 finalizer of one of the objects in the cycle -- but only, of course, if

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. + + +Destructors +----------- + +A destructor is an RPython ``__del__()`` method that is called directly +by the GC when there is no more reference to an object. Intended for +objects that just need to free a block of raw memory or close a file. + +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; +and if you call an external C function, it must be a "safe" function +(e.g. not releasing the GIL; use ``releasegil=False`` in +``rffi.llexternal()``). + +If there are several objects with destructors that die during the same +GC cycle, they are called in a completely random order --- but that +should not matter because destructors cannot do much anyway. + + +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. + +It is allowed in theory to 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. + + +Ordering of finalizers +---------------------- + +After a collection, the MiniMark GC should call the finalizers on *some* of the objects that have one and that have become unreachable. Basically, if there is a reference chain from an object a to an object b then it should not call the finalizer for b immediately, but just keep b alive and try again to call its finalizer after the next collection. -This basic idea fails when there are cycles.

CPython defines many macros like so: #define PyWhatever_FOO(x) (((PyWhatever*)(x))->foo) And callers can pass in a `void*`, a `PyWhatever*`, a `PyObject*`, and it all works assuming that the dynamic type is correct for the cast.

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. + +It is allowed in theory to 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. + + +Ordering of finalizers +---------------------- + +After a collection, the MiniMark GC should call the finalizers on *some* of the objects that have one and that have become unreachable. Basically, if there is a reference chain from an object a to an object b then it should not call the finalizer for b immediately, but just keep b alive and try again to call its finalizer after the next collection. -This basic idea fails when there are cycles.

Instead we use + ``rgc.FinalizerController.register_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. + +Note that the Boehm garbage collector, used in ``rpython -O0``, +completely ignores ``register_finalizer()``. + + +Ordering of finalizers +---------------------- + +After a collection, the MiniMark GC should call the finalizers on *some* of the objects that have one and that have become unreachable. Basically, if there is a reference chain from an object a to an object b then it should not call the finalizer for b immediately, but just keep b alive and try again to call its finalizer after the next collection. -This basic idea fails when there are cycles.

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.

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. + From pypy.commits at gmail.com Wed May 11 14:22:05 2016 From: pypy.commits at gmail.com (rlamy) Date: Wed, 11 May 2016 11:22:05 -0700 (PDT) Subject: [pypy-commit] pypy default: turn make_wrapper() into a method of ApiFunction Message-ID: <5733784d.882cc20a.65186.4100@mx.google.com> Author: Ronan Lamy Branch: Changeset: r84383:51732368583f Date: 2016-05-11 19:21 +0100 http://bitbucket.org/pypy/pypy/changeset/51732368583f/ Log: turn make_wrapper() into a method of ApiFunction diff --git a/pypy/module/cpyext/api.py b/pypy/module/cpyext/api.py --- a/pypy/module/cpyext/api.py +++ b/pypy/module/cpyext/api.py @@ -203,46 +203,46 @@ # id.

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. + +Note that the Boehm garbage collector, used in ``rpython -O0``, +completely ignores ``register_finalizer()``. + + +Ordering of finalizers +---------------------- + +After a collection, the MiniMark GC should call the finalizers on *some* of the objects that have one and that have become unreachable. Basically, if there is a reference chain from an object a to an object b then it should not call the finalizer for b immediately, but just keep b alive and try again to call its finalizer after the next collection. -This basic idea fails when there are cycles.

In PyPy, without these casts, a warning is emitted if you pass the "wrong" type, even though it would work in CPython. This breaks compatibility for projects that build with -Werror. Fixed by declaring PyWhatever_FOO() as taking a "void *" as a first argument. It is not 100% exactly what CPython does, but it will accept any kind of pointer. diff --git a/pypy/module/cpyext/api.py b/pypy/module/cpyext/api.py --- a/pypy/module/cpyext/api.py +++ b/pypy/module/cpyext/api.py @@ -410,7 +410,16 @@ arg = rffi.cast(ARG, as_pyobj(space, input_arg)) else: arg = rffi.cast(ARG, input_arg) - elif is_PyObject(ARG) and is_wrapped: + elif ARG == rffi.VOIDP and not is_wrapped: + # unlike is_PyObject case above, we allow any kind of + # argument -- just, if it's an object, we assume the + # caller meant for it to become a PyObject*. + if input_arg is None or isinstance(input_arg, W_Root): + keepalives += (input_arg,) + arg = rffi.cast(ARG, as_pyobj(space, input_arg)) + else: + arg = rffi.cast(ARG, input_arg) + elif (is_PyObject(ARG) or ARG == rffi.VOIDP) and is_wrapped: # build a W_Root, possibly from a 'PyObject *' if is_pyobj(input_arg): arg = from_ref(space, input_arg) @@ -842,6 +851,10 @@ if is_PyObject(typ) and is_wrapped: assert is_pyobj(arg) arg_conv = from_ref(space, rffi.cast(PyObject, arg)) + elif typ == rffi.VOIDP and is_wrapped: + # Many macros accept a void* so that one can pass a + # PyObject* or a PySomeSubtype*. + arg_conv = from_ref(space, rffi.cast(PyObject, arg)) else: arg_conv = arg boxed_args += (arg_conv, ) diff --git a/pypy/module/cpyext/cdatetime.py b/pypy/module/cpyext/cdatetime.py --- a/pypy/module/cpyext/cdatetime.py +++ b/pypy/module/cpyext/cdatetime.py @@ -178,67 +178,67 @@ # Accessors - at cpython_api([PyDateTime_Date], rffi.INT_real, error=CANNOT_FAIL) + at cpython_api([rffi.VOIDP], rffi.INT_real, error=CANNOT_FAIL) def PyDateTime_GET_YEAR(space, w_obj): """Return the year, as a positive int.

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. + +Note that the Boehm garbage collector, used in ``rpython -O0``, +completely ignores ``register_finalizer()``. + + +Ordering of finalizers +---------------------- + +After a collection, the MiniMark GC should call the finalizers on *some* of the objects that have one and that have become unreachable. Basically, if there is a reference chain from an object a to an object b then it should not call the finalizer for b immediately, but just keep b alive and try again to call its finalizer after the next collection. -This basic idea fails when there are cycles.

This is done by removing most of the _ovf, _zer and _val operations from RPython. Left: only int_add_ovf, int_sub_ovf and int_mul_ovf. Handling of all the other cases is done in rint.py. This gives more flexibility, which we use in the JIT for '/' and '%'. Now the JIT sees the Python-style behavior wrt negative arguments to '/' and '%', instead of the C-style one. This in turn allows the JIT to do better optimizations: for example, app-level code like 'x % 2' can now be turned into 'int_and 1' even if x is possibly negative. The JIT backends no longer directly support div and mod, which removes quite a lot of mess in the ARM case. In fact, even where the CPU supports division, it's a very slow operation (particularly on 64-bit), so the overhead of calling a helper is small (and anyway it is usually needed now, to do the C-to-Python-style corrections). diff too long, truncating to 2000 out of 3566 lines diff --git a/pypy/module/__pypy__/interp_intop.py b/pypy/module/__pypy__/interp_intop.py --- a/pypy/module/__pypy__/interp_intop.py +++ b/pypy/module/__pypy__/interp_intop.py @@ -2,6 +2,19 @@ from rpython.rtyper.lltypesystem import lltype from rpython.rtyper.lltypesystem.lloperation import llop from rpython.rlib.rarithmetic import r_uint, intmask +from rpython.rlib import jit + + +# XXX maybe temporary: hide llop.int_{floordiv,mod} from the JIT, +# because now it expects only Python-style divisions, not the +# C-style divisions of these two ll operations + at jit.dont_look_inside +def _int_floordiv(n, m): + return llop.int_floordiv(lltype.Signed, n, m) + + at jit.dont_look_inside +def _int_mod(n, m): + return llop.int_mod(lltype.Signed, n, m) @unwrap_spec(n=int, m=int) @@ -18,11 +31,11 @@ @unwrap_spec(n=int, m=int) def int_floordiv(space, n, m): -

+===================
+PyPy3 v5.2 alpha 1
+===================
+
+We're pleased to announce the first alpha release of PyPy3.3 v5.2. This is the
+first release of PyPy which targets Python 3.3 (3.3.5) compatibility.
+
+We would like to thank all of the people who donated_ to the `py3k proposal`_
+for supporting the work that went into this and future releases.
+
+You can download the PyPy3.3 v5.2 alpha 1 release here:
+
+    http://pypy.org/download.html#python-3-3-5-compatible-pypy3-3-v5-2
+
+Highlights
+==========
+
+* Python 3.3.5 support!
+
+  - Being an early alpha release, there are some `missing features`_ such as a
+    `PEP 393-like space efficient string representation`_ and `known issues`_
+    including performance regressions (e.g. issue `#2305`_). The focus for this
+    release has been updating to 3.3 compatibility. Windows is also not yet
+    supported.
+
+* `ensurepip`_ is also included (it's only included in CPython 3 >= 3.4).
+
+What is PyPy?
+==============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.10 and one day 3.3.5. It's fast due to its integrated tracing JIT
+compiler.
+
+We also welcome developers of other `dynamic languages`_ to see what RPython
+can do for them.
+
+This release supports:
+
+  * **x86** machines on most common operating systems except Windows
+    (Linux 32/64, Mac OS X 64, OpenBSD, FreeBSD),
+
+  * newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux,
+
+  * big- and little-endian variants of **PPC64** running Linux,
+
+  * **s390x** running Linux
+
+Please try it out and let us know what you think. We welcome feedback, we know
+you are using PyPy, please tell us about it!
+
+We'd especially like to thank these people for their contributions to this
+release:
+
+Manuel Jacob, Ronan Lamy, Mark Young, Amaury Forgeot d'Arc, Philip Jenvey,
+Martin Matusiak, Vasily Kuznetsov, Matti Picus, Armin Rigo and many others.
+
+Cheers
+

 Fix some warnings when compiling CPython C extension modules
 
 .. branch: syntax_fix
+
+.. branch: remove-raisingops
+
+Remove most of the _ovf, _zer and _val operations from RPython.  Kills
+quite some code internally, and allows the JIT to do better
+optimizations: for example, app-level code like ``x / 2`` or ``x % 2``
+can now be turned into ``x >> 1`` or ``x & 1``, even if x is possibly
+negative.
+
+.. branch: cpyext-old-buffers
+
+Generalize cpyext old-style buffers to more than just str/buffer, add support for mmap
+
+.. branch: numpy-includes
+
+Move _numpypy headers into a directory so they are not picked up by upstream numpy, scipy
+This allows building upstream numpy and scipy in pypy via cpyext
+
+.. branch: traceviewer-common-merge-point-formats
+
+Teach RPython JIT's off-line traceviewer the most common ``debug_merge_point`` formats.

 mentioned in last commit.
Message-ID: <574dfb36.c7b81c0a.f3eb.ffffb948@mx.google.com>

http://bitbucket.org/pypy/pypy/changeset/11bee4605bdc/

Log:	Fix type unification problem mentioned in last commit.

	A remaining issue is a problem with test_newgc.py like so:

	data_rpython_memory_test.c:17655:4: error: ‘pypy_g_header_1433’
	undeclared here (not in a function) (&pypy_g_header_1433.h_tid), /*
	gcheader.remote_flags */

	Interesting! I'll try to fix separately (maybe hg bisect will help
	here.)

+===================
+PyPy3 v5.2 alpha 1
+===================
+
+We're pleased to announce the first alpha release of PyPy3.3 v5.2. This is the
+first release of PyPy which targets Python 3.3 (3.3.5) compatibility.
+
+We would like to thank all of the people who donated_ to the `py3k proposal`_
+for supporting the work that went into this and future releases.
+
+You can download the PyPy3.3 v5.2 alpha 1 release here:
+
+    http://pypy.org/download.html#python-3-3-5-compatible-pypy3-3-v5-2
+
+Highlights
+==========
+
+* Python 3.3.5 support!
+
+  - Being an early alpha release, there are some `missing features`_ such as a
+    `PEP 393-like space efficient string representation`_ and `known issues`_
+    including performance regressions (e.g. issue `#2305`_). The focus for this
+    release has been updating to 3.3 compatibility. Windows is also not yet
+    supported.
+
+* `ensurepip`_ is also included (it's only included in CPython 3 >= 3.4).
+
+What is PyPy?
+==============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.10 and one day 3.3.5. It's fast due to its integrated tracing JIT
+compiler.
+
+We also welcome developers of other `dynamic languages`_ to see what RPython
+can do for them.
+
+This release supports:
+
+  * **x86** machines on most common operating systems except Windows
+    (Linux 32/64, Mac OS X 64, OpenBSD, FreeBSD),
+
+  * newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux,
+
+  * big- and little-endian variants of **PPC64** running Linux,
+
+  * **s390x** running Linux
+
+Please try it out and let us know what you think. We welcome feedback, we know
+you are using PyPy, please tell us about it!
+
+We'd especially like to thank these people for their contributions to this
+release:
+
+Manuel Jacob, Ronan Lamy, Mark Young, Amaury Forgeot d'Arc, Philip Jenvey,
+Martin Matusiak, Vasily Kuznetsov, Matti Picus, Armin Rigo and many others.
+
+Cheers
+
+The PyPy Team

 Use the new rgc.FinalizerQueue mechanism to clean up the handling of

+
+Implement ufunc.outer on numpypy
+
+.. branch: verbose-imports
+
+Support ``pypy -v``: verbose imports.  It does not log as much as
+cpython, but it should be enough to help when debugging package layout
+problems.
+
+.. branch: cpyext-macros-cast
+
+Fix some warnings when compiling CPython C extension modules
+
+.. branch: syntax_fix
+
+.. branch: remove-raisingops
+
+Remove most of the _ovf, _zer and _val operations from RPython.  Kills
+quite some code internally, and allows the JIT to do better
+optimizations: for example, app-level code like ``x / 2`` or ``x % 2``
+can now be turned into ``x >> 1`` or ``x & 1``, even if x is possibly
+negative.
+
+.. branch: cpyext-old-buffers
+
+Generalize cpyext old-style buffers to more than just str/buffer, add support for mmap
+
+.. branch: numpy-includes
+
+Move _numpypy headers into a directory so they are not picked up by upstream numpy, scipy
+This allows building upstream numpy and scipy in pypy via cpyext
+
+.. branch: traceviewer-common-merge-point-formats
+
+Teach RPython JIT's off-line traceviewer the most common ``debug_merge_point`` formats.

 direct_fieldptr by lazily initializing the gc header.

Log:	Fix broken translation of direct_fieldptr by lazily initializing the
	gc header.

	(The direct_fieldptr call was occurring in the initialization of a
	static value, where there was nothing to take the address *of*!)

	Tests still fail, in an even more opaque way now: segfaulting.
	Woooooo...
