bpo-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231) 
The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty:
they have been doing nothing for the last year  (since commit
735ae8d139), so stop using them.

bpo-37206: Unrepresentable default values no longer represented as None. (GH-13933) 
In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values
(like in the optional third parameter of getattr). "None" should be used if None is accepted
as argument and passing None has the same effect as not passing the argument at all.

Make PyXXX_Fini() functions private (GH-15531) 
For example, rename PyTuple_Fini() to _PyTuple_Fini().

These functions are only declared in the internal C API.

bpo-35713: Split _Py_InitializeCore into subfunctions (GH-11650) 
* Split _Py_InitializeCore_impl() into subfunctions: add multiple pycore_init_xxx() functions
* Preliminary sys.stderr is now set earlier to get an usable
  sys.stderr ealier.
* Move code into _Py_Initialize_ReconfigureCore() to be able to call
  it from _Py_InitializeCore().
* Split _PyExc_Init(): create a new _PyBuiltins_AddExceptions()
  function.
* Call _PyExc_Init() earlier in _Py_InitializeCore_impl()
  and new_interpreter() to get working exceptions earlier.
* _Py_ReadyTypes() now returns _PyInitError rather than calling
  Py_FatalError().
* Misc code cleanup

2bb69a5b4e bpo-31373: remove overly strict float range checks (#3486) 
This undoes a853a8ba78 except for the pytime.c
parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be
rounded into finite floats. Tests were added to very this behavior.

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.

16931c3559 Issue #26983: float() now always return an instance of exact float. 
The deprecation warning is emitted if __float__ returns an instance of

be an error.

eeb896c411 Issue #24802: Copy bytes-like objects to null-terminated buffers if necessary 
This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.
