* Add _PY_FASTCALL_SMALL_STACK constantVictor Stinner2016-12-151-1/+1
| | | | | | | | | Issue #28870: Add a new _PY_FASTCALL_SMALL_STACK constant, size of "small stacks" allocated on the C stack to pass positional arguments to _PyObject_FastCall(). _PyObject_Call_Prepend() now uses a small stack of 5 arguments (40 bytes) instead of 8 (64 bytes), since it is modified to use _PY_FASTCALL_SMALL_STACK.

| * Issue #23722: improve __classcell__ compatibilityNick Coghlan2016-12-051-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling zero-argument super() in __init_subclass__ and __set_name__ involved moving __class__ initialisation to type.__new__. This requires cooperation from custom metaclasses to ensure that the new __classcell__ entry is passed along appropriately. The initial implementation of that change resulted in abruptly broken zero-argument super() support in metaclasses that didn't adhere to the new requirements (such as Django's metaclass for Model definitions). The updated approach adopted here instead emits a deprecation warning for those cases, and makes them work the same way they did in Python 3.5. This patch also improves the related class machinery documentation to cover these details and to include more reader-friendly cross-references and index entries.
* | Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-4/+4
| | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

* Issue #23722: Initialize __class__ from type.__new__()Nick Coghlan2016-09-111-6/+4
| | | | | | | | | The __class__ cell used by zero-argument super() is now initialized from type.__new__ rather than __build_class__, so class methods relying on that will now work correctly when called from metaclass methods during class creation. Patch by Martin Teichmann.
