Serhiy Storchaka ba85d69a3e bpo-29878: Add global instances of int for 0 and 1. (#852) 2017-03-30 09:09:41 +03:00
Serhiy Storchaka fff9a31a91 bpo-29865: Use PyXXX_GET_SIZE macros rather than Py_SIZE for concrete types. (#748) 2017-03-21 08:53:25 +02:00
Serhiy Storchaka 5ab81d787f Issue #28959: Added private macro PyDict_GET_SIZE for retrieving the size of dict. 2016-12-16 16:18:57 +02:00
Victor Stinner de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner 27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* 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.

Serhiy Storchaka 1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR. 
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
