* | Rework CALL_FUNCTION* opcodesVictor Stinner2016-09-091-287/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more efficient bytecode: * CALL_FUNCTION now only accepts position arguments * CALL_FUNCTION_KW accepts position arguments and keyword arguments, but keys of keyword arguments are packed into a constant tuple. * CALL_FUNCTION_EX is the most generic, it expects a tuple and a dict for positional and keyword arguments. CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed. 2 tests of test_traceback are currently broken: skip test, the issue #28050 was created to track the issue. Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka and Victor Stinner.

| |
* | Add _PyObject_FastCallKeywords()Victor Stinner2016-08-241-9/+14
| | | | | | | | | | | | 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.
* | Use Py_ssize_t type for number of argumentsVictor Stinner2016-08-241-83/+114
| | | | | | | | | | Issue #27848: use Py_ssize_t rather than C int for the number of function positional and keyword arguments.
* | PyEval_CallObjectWithKeywords() doesn't inc/decrefVictor Stinner2016-08-221-7/+1
| | | | | | | | | | | | 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.
* | PyEval_CallObjectWithKeywords() uses fast call with kwargsVictor Stinner2016-08-221-12/+4
| | | | | | | | | | 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 _PyFunction_FastCall() to _PyFunction_FastCallDict() * Rename _PyCFunction_FastCall() to _PyCFunction_FastCallDict() * _PyFunction_FastCallDict() now supports keyword arguments
* | Rename _PyObject_FastCall() to _PyObject_FastCallDict()Victor Stinner2016-08-221-2/+2
| | | | | | | | | | | | | | | | Issue #27809: * Rename _PyObject_FastCall() function to _PyObject_FastCallDict() * Add _PyObject_FastCall(), _PyObject_CallNoArg() and _PyObject_CallArg1() macros calling _PyObject_FastCallDict()
* | Optimize call to Python function without argumentVictor Stinner2016-08-221-11/+31
| | | | | | | | | | | | 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.
* | import_name() now uses fast callVictor Stinner2016-08-191-13/+9
| | | | | | | | | | Issue #27128: import_name() now calls _PyObject_FastCall() to avoid the creation of a temporary tuple.
* | Fix PyObject_Call() parameter namesVictor Stinner2016-08-191-12/+13
| | | | | | | | | | | | Issue #27128: arg=>args, kw=>kwargs. Same change for PyEval_CallObjectWithKeywords().
* | PyEval_CallObjectWithKeywords() uses fast callVictor Stinner2016-08-191-0/+4
| | | | | | | | | | | | 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.
* | Add _PyObject_FastCall()Victor Stinner2016-08-191-46/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | Use Py_ssize_t in _PyEval_EvalCodeWithName()Victor Stinner2016-08-161-8/+10
| | | | | | | | | | | | | | | | 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.
