| | | | | | | | Issue #28782: Fix a bug in the implementation ``yield from`` when checking if the next instruction is YIELD_FROM. Regression introduced by WORDCODE (issue #26647). Reviewed by Serhiy Storchaka and Yury Selivanov.

| | | | | | | | | | | | As it was agreed in the issue, __aiter__ returning an awaitable should result in PendingDeprecationWarning in 3.5 and in DeprecationWarning in 3.6.

* | Issue #27213: Fixed different issues with reworked CALL_FUNCTION* opcodes.Serhiy Storchaka2016-09-121-84/+57
| | | | | | | | | | | | | | | | | | | | | | * BUILD_TUPLE_UNPACK and BUILD_MAP_UNPACK_WITH_CALL no longer generated with single tuple or dict. * Restored more informative error messages for incorrect var-positional and var-keyword arguments. * Removed code duplications in _PyEval_EvalCodeWithName(). * Removed redundant runtime checks and parameters in _PyStack_AsDict(). * Added a workaround and enabled previously disabled test in test_traceback. * Removed dead code from the dis module.

* | DTrace support: function calls, GC activity, line execution?ukasz Langa2016-09-091-2/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc. Largely based by an initial patch by Jes?s Cea Avi?n, with some influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's unification patch. Things deliberately left out for simplicity: - ustack helpers, I have no way of testing them at this point since they are Solaris-specific - PyFrameObject * in function__entry/function__return, this is SystemTap-specific - SPARC support - dynamic tracing - sys module dtrace facility introspection All of those might be added later.

* | Issue #27810: Add _PyCFunction_FastCallKeywords()Victor Stinner2016-09-091-136/+28
| | | | | | | | | | Use _PyCFunction_FastCallKeywords() in ceval.c: it allows to remove a lot of code from ceval.c which was only used to call C functions.
* | Add _PyObject_FastCallKeywords()Victor Stinner2016-09-091-53/+36
| | | | | | | | | | | | | | | | | | | | Issue #27830: Add _PyObject_FastCallKeywords(): avoid the creation of a temporary dictionary for keyword arguments. Other changes: * Cleanup call_function() and fast_function() (ex: rename nk to nkwargs) * Remove now useless do_call(), replaced with _PyObject_FastCallKeywords()
* | 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 Stinner2016-08-251-9/+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 Stinner2016-08-251-83/+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 Stinner2016-08-231-7/+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.

* | 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 Stinner2016-08-201-13/+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.
| * Issue #27128: Cleanup _PyEval_EvalCodeWithName()Victor Stinner2016-08-161-11/+43
| | | | | | | | | | | | | | | | * Add comments * Add empty lines for readability * PEP 7 style for if block * Remove useless assert(globals != NULL); (globals is tested a few lines before)
