Victor Stinner ad8c83ad6b Avoid inefficient way to call functions without argument 
Don't pass "()" format to PyObject_CallXXX() to call a function without
argument: pass NULL as the format string instead. It avoids to have to parse a
string to produce 0 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.

Victor Stinner 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
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

Victor Stinner 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.

Victor Stinner cecdd9634b Issue #27776: _PyRandom_Init() doesn't call PyErr_CheckSignals() anymore 
Modify py_getrandom() to not call PyErr_CheckSignals() if raise is zero.
_PyRandom_Init() is called very early in the Python initialization, so it's
safer to not call PyErr_CheckSignals().
 2016-08-16 15:19:09 +02:00
Victor Stinner 4bad3b622e Issue #27776: Cleanup random.c 
* Add pyurandom() helper function to factorize the code

Nick Coghlan d00342347e Issue #26823: Abbreviate recursive tracebacks
