* bpo-35134: Create Include/cpython/abstract.h (GH-10728)Victor Stinner2018-11-261-281/+4
| | | | Move abstract.h code surrounded by "#ifndef Py_LIMITED_API" to a new Include/cpython/abstract.h header file.
* Clean up after bpo-33738. (GH-7627)Serhiy Storchaka2018-06-111-4/+2
| | | | | * Add declarations even if they are overridden by macros. * Make the declaration and the definition of PyExceptionClass_Name consistent.

* bpo-33738: Fix macros which contradict PEP 384 (GH-7477)Christian Tismer2018-06-091-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During development of the limited API support for PySide, we saw an error in a macro that accessed a type field. This patch fixes the 7 errors in the Python headers. Macros which were not written as capitals were implemented as function. To do the necessary analysis again, a script was included that parses all headers and looks for "->tp_" in serctions which can be reached with active limited API. It is easily possible to call this script as a test. Error listing: ../../Include/objimpl.h:243 #define PyObject_IS_GC(o) (PyType_IS_GC(Py_TYPE(o)) && \ (Py_TYPE(o)->tp_is_gc == NULL || Py_TYPE(o)->tp_is_gc(o))) Action: commented only ../../Include/objimpl.h:362 #define PyType_SUPPORTS_WEAKREFS(t) ((t)->tp_weaklistoffset > 0) Action: commented only ../../Include/objimpl.h:364 #define PyObject_GET_WEAKREFS_LISTPTR(o) \ ((PyObject **) (((char *) (o)) + Py_TYPE(o)->tp_weaklistoffset)) Action: commented only ../../Include/pyerrors.h:143 #define PyExceptionClass_Name(x) \ ((char *)(((PyTypeObject*)(x))->tp_name)) Action: implemented function ../../Include/abstract.h:593 #define PyIter_Check(obj) \ ((obj)->ob_type->tp_iternext != NULL && \ (obj)->ob_type->tp_iternext != &_PyObject_NextNotImplemented) Action: implemented function ../../Include/abstract.h:713 #define PyIndex_Check(obj) \ ((obj)->ob_type->tp_as_number != NULL && \ (obj)->ob_type->tp_as_number->nb_index != NULL) Action: implemented function ../../Include/abstract.h:924 #define PySequence_ITEM(o, i)\ ( Py_TYPE(o)->tp_as_sequence->sq_item(o, i) ) Action: commented only

| | | | | | | | * Add _PyObject_HasFastCall() * partial_call() now avoids temporary tuple to pass positional arguments if the callable supports the FASTCALL calling convention for positional arguments. * Fix also a performance regression in partial_call() if the callable doesn't support FASTCALL.
* Optimize slots: avoid temporary PyMethodObjectVictor Stinner2017-02-091-0/+6
| | | | | | | | | | | | | | | | | | Issue #29507: Optimize slots calling Python methods. For Python methods, get the unbound Python function and prepend arguments with self, rather than calling the descriptor which creates a temporary PyMethodObject. Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python method with self. It avoids the creation of a temporary tuple to pass positional arguments. Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented in Python: Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%) Co-Authored-by: INADA Naoki <songofacandy@gmail.com>
* Issue #29360: _PyStack_AsDict() doesn't check kwnamesVictor Stinner2017-01-241-6/+9

* call_method() now uses _PyObject_FastCall()Victor Stinner2017-01-101-8/+0
| | | | | | | | | | | | | | | | | | | Issue #29233: Replace the inefficient _PyObject_VaCallFunctionObjArgs() with _PyObject_FastCall() in call_method() and call_maybe(). Only a few functions call call_method() and call it with a fixed number of arguments. Avoid the complex and expensive _PyObject_VaCallFunctionObjArgs() function, replace it with an array allocated on the stack with the exact number of argumlents. It reduces the stack consumption, bytes per call, before => after: test_python_call: 1168 => 1152 (-16 B) test_python_getitem: 1344 => 1008 (-336 B) test_python_iterator: 1568 => 1232 (-336 B) Remove the _PyObject_VaCallFunctionObjArgs() function which became useless. Rename it to object_vacall() and make it private.

* | Add _PY_FASTCALL_SMALL_STACK constantVictor Stinner2016-12-151-0/+11
| | | | | | | | | | | | | | | | | | Issue #28870: Add a new _PY_FASTCALL_SMALL_STACK constant, size of "small stacks" allocated on the C stack to pass positional arguments to _PyObject_FastCall(). _PyObject_Call_Prepend() now uses a small stack of 5 arguments (40 bytes) instead of 8 (64 bytes), since it is modified to use _PY_FASTCALL_SMALL_STACK.
* | Issue #28838: Cleanup abstract.hVictor Stinner2016-12-151-621/+423
| | | | | | | | | | | | | | | | | | | | Rewrite all comments to use the same style than other Python header files: comment functions *before* their declaration, no newline between the comment and the declaration. Reformat some comments, add newlines, to make them easier to read. Quote argument like 'arg' to mention an argument in a comment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.
