Victor Stinner
577e1f8cb4 Add _PyObject_FastCallKeywords() 
Issue #27830: Similar to _PyObject_FastCallDict(), but keyword arguments are
also passed in the same C array than positional arguments, rather than being
passed as a Python dict.

74319ae219 Use Py_ssize_t type for number of arguments 
Issue #27848: use Py_ssize_t rather than C int for the number of function
positional and keyword arguments.

6e2333dfdf PyEval_CallObjectWithKeywords() doesn't inc/decref 
Issue #27809: PyEval_CallObjectWithKeywords() doesn't increment temporary the
reference counter of the args tuple (positional arguments). The caller already
holds a strong reference to it.

155ea65e5c PyEval_CallObjectWithKeywords() uses fast call with kwargs 
Issue #27809. _PyObject_FastCallDict() now supports keyword arguments, and so
the args==NULL fast-path can also be used when kwargs is not NULL.

Issue #27809:

* Rename _PyCFunction_FastCall() to _PyCFunction_FastCallDict()
*  _PyFunction_FastCallDict() now supports keyword arguments

559bb6a713 Rename _PyObject_FastCall() to _PyObject_FastCallDict() 
Issue #27809:

* Rename _PyObject_FastCall() function to _PyObject_FastCallDict()
* Add _PyObject_FastCall(), _PyObject_CallNoArg() and _PyObject_CallArg1()
  macros calling _PyObject_FastCallDict()

2eedc119c2 Optimize call to Python function without argument 
Issue #27128. When a Python function is called with no arguments, but all
parameters have a default value: use default values as arguments for the fast
path.

df142fdc4b import_name() now uses fast call 
Issue #27128: import_name() now calls _PyObject_FastCall() to avoid the
creation of a temporary tuple.

3f745bf1d9 PyEval_CallObjectWithKeywords() uses fast call 
Issue #27128: Modify PyEval_CallObjectWithKeywords() to use
_PyObject_FastCall() when args==NULL and kw==NULL. It avoids the creation of a
temporary empty tuple for positional arguments.
 2016-08-19 16:42:42 +02:00

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

eec9331b20 Fix SystemError in "raise" statement 
Issue #27558: Fix a SystemError in the implementation of "raise" statement.

exception to reraise.

17061a99b0 Use Py_ssize_t in _PyEval_EvalCodeWithName() 
Issue #27128, #18295: replace int type with Py_ssize_t for index variables used
for positional arguments. It should help to avoid integer overflow and help to
emit better machine code for "i++" (no trap needed for overflow).

Make also the total_args variable constant.

  before)
