Issue #20186: Converted builtins enumerate() and reversed() to Argument Clinic.

2017-01-19T16:48:17+00:00

Patch by Tal Einat.

Use _PyObject_CallNoArg()

2016-12-06T17:46:19+00:00

Replace:
    PyObject_CallFunctionObjArgs(callable, NULL)
with:
    _PyObject_CallNoArg(callable)

Backed out changeset b9c9691c72c5

2016-12-04T21:59:09+00:00

Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().

Replace PyObject_CallFunctionObjArgs() with fastcall

2016-12-01T13:43:22+00:00

* 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.

Anti-registration of various ABC methods.

2016-08-18T16:22:23+00:00

- Issue #25958: Support "anti-registration" of special methods from
  various ABCs, like __hash__, __iter__ or __len__.  All these (and
  several more) can be set to None in an implementation class and the
  behavior will be as if the method is not defined at all.
  (Previously, this mechanism existed only for __hash__, to make
  mutable classes unhashable.)  Code contributed by Andrew Barnert and
  Ivan Levkivskyi.

Issue #14288: Serialization support for builtin iterators.

2012-04-03T10:49:41+00:00

use the static identifier api for looking up special methods

2012-01-22T16:24:29+00:00

I had to move the static identifier code from unicodeobject.h to object.h in
order for this to work.
