Victor Stinner 20a3007a8d slot_nb_bool() now uses fast call
Issue #27128: slot_nb_bool() now calls _PyObject_FastCall() to avoid a
temporary empty tuple to call the slot function.
2016-08-19 18:28:25 +02:00
Victor Stinner a12eec48b6 Issue #27128: Cleanup slot_nb_bool()

Victor Stinner 5e87749a8e Issue #27128: slot_sq_item() uses fast call
slot_sq_item() now calls _PyObject_FastCall() to avoid the creation of a
temporary tuple of 1 item to pass the 'item' argument to the slot function.
2016-08-19 18:19:42 +02:00
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
* Replace Py_XDECREF(func) with Py_DECREF(func) in the error block: func cannot
  be NULL when reaching the error block

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()
2016-08-19 16:44:19 +02:00
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 f3914eb16d co_lnotab supports negative line number delta
Issue #26107: The format of the co_lnotab attribute of code objects changes to

Changes:

* assemble_lnotab(): if line number delta is less than -128 or greater than
  127, emit multiple (offset_delta, lineno_delta) in co_lnotab
* update functions decoding co_lnotab to use signed 8-bit integers

  - dis.findlinestarts()
  - PyCode_Addr2Line()
  - _PyCode_CheckLineNumber()
  - frame_setlineno()

* update lnotab_notes.txt
* increase importlib MAGIC_NUMBER to 3361
* document the change in What's New in Python 3.6
* cleanup also PyCode_Optimize() to use better variable names

Issue #26154: Add a new private _PyThreadState_UncheckedGet() function.
2016-01-20 11:19:46 +01:00
Victor Stinner bfd316e750 Add _PyThreadState_UncheckedGet()
Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which
gets the current thread state, but don't call Py_FatalError() if it is NULL.

Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to
no more expose complex and private atomic types. Atomic types depends on the
compiler or can even depend on compiler options. The new function
_PyThreadState_UncheckedGet() allows to get the variable value without having
to care of the exact implementation of atomic types.

Changes:

* Replace direct usage of the _PyThreadState_Current variable with a call to
  _PyThreadState_UncheckedGet().
* In pystate.c, replace direct usage of the _PyThreadState_Current variable
  with the PyThreadState_GET() macro for readability.
* Document also PyThreadState_Get() in pystate.h
