Victor Stinner	de4ae3d486	Backed out changeset b9c9691c72c5 Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().	10 years ago
Victor Stinner	4778eab1f2	Replace PyObject_CallFunction() with fastcall Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.	10 years ago
Victor Stinner	27580c1fb5	Replace PyObject_CallFunctionObjArgs() with fastcall * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.	10 years ago
Victor Stinner	8be1c39eb3	Backed out changeset 7efddbf1aa70	10 years ago
Victor Stinner	ebea9988e0	Uniformize argument names of "call" functions * Callable object: callable, o, callable_object => func * Object for method calls: o => obj * Method name: name or nameid => method Cleanup also the C code: * Don't initialize variables to NULL if they are not used before their first assignement * Add braces for readability	10 years ago
Serhiy Storchaka	9ec07721f4	Issue #28797 : Modifying the class __dict__ inside the __set_name__ method of a descriptor that is used inside that class no longer prevents calling the __set_name__ method of other descriptors.	10 years ago

Victor Stinner	c6944e7edc	Issue #28618 : Make hot functions using __attribute__((hot)) When Python is not compiled with PGO, the performance of Python on call_simple and call_method microbenchmarks depend highly on the code placement. In the worst case, the performance slowdown can be up to 70%. The GCC __attribute__((hot)) attribute helps to keep hot code close to reduce the risk of such major slowdown. This attribute is ignored when Python is compiled with PGO. The following functions are considered as hot according to statistics collected by perf record/perf report: * _PyEval_EvalFrameDefault() * call_function() * _PyFunction_FastCall() * PyFrame_New() * frame_dealloc() * PyErr_Occurred()	10 years ago
