Victor Stinner 5e87749a8e Issue #27128: slot_sq_item() uses fast call 
slot_sq_item() now calls _PyObject_FastCall() to avoid the creation of a

Victor Stinner 018016d8e3 Issue #27128: Cleanup slot_sq_item() 
* Invert condition of test to avoid levels of indentation
* Remove useless Py_XDECREF(args) in the error block

  be NULL when reaching the error block

Victor Stinner f736c261a2 call_method() and call_maybe() now use fast call 
Issue #27128. The call_method() and call_maybe() functions of typeobject.c now
use fast call for empty format string to avoid the creation of a temporary
empty tuple.

Victor Stinner 0d1a799343 Avoid call_function_tail() for empty format str 
Issue #27128, PyObject_CallFunction(), _PyObject_FastCall() and callmethod():
if the format string of parameters is empty, avoid the creation of an empty
tuple: call _PyObject_FastCall() without parameters.

Victor Stinner 71aea8e981 PEP 7: add {...} around null_error() in abstract.c 
Issue #27128.

Victor Stinner d042f1f5eb Cleanup callmethod() 
Make callmethod() less weird: don't decrement func reference counter,
the caller is now responsible to do that.

Issue #27128.
 2016-08-19 16:56:49 +02:00
Victor Stinner 64faad6e45 Cleanup call_function_tail() 
Make call_function_tail() less weird: don't decrement args reference counter,
the caller is now responsible to do that. The caller now also checks if args is
NULL.

Issue #27128.

Victor Stinner 8880708f81 call_function_tail() uses fast call 
Issue #27128: Modify call_function_tail() to use _PyObject_FastCall() when args
is not a tuple to avoid the creation of a temporary tuple.

call_function_tail() is used by:

* PyObject_CallFunction()
* PyObject_CallMethod()
* _PyObject_CallMethodId()

Victor Stinner 9be7e7b52f Add _PyObject_FastCall() 
Issue #27128: Add _PyObject_FastCall(), a new calling convention avoiding a
temporary tuple to pass positional parameters in most cases, but create a
temporary tuple if needed (ex: for the tp_call slot).

The API is prepared to support keyword parameters, but the full implementation
will come later (_PyFunction_FastCall() doesn't support keyword parameters
yet).

Add also:

* _PyStack_AsTuple() helper function: convert a "stack" of parameters to
  a tuple.
* _PyCFunction_FastCall(): fast call implementation for C functions
* _PyFunction_FastCall(): fast call implementation for Python functions

Guido van Rossum 97c1adf393 Anti-registration of various ABC methods. 
- 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.

Victor Stinner 8bcf312d09 Issue #27786: Simplify x_sub()

can be used directly to negate the number.
