| | | | | | | * | | | Issue #20185: Convert _warnings.warn() to Argument ClinicVictor Stinner2016-12-092-16/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix warn_explicit(): interpret source=None as source=NULL.
| | | | | | | * | | | Inline PyEval_EvalFrameEx() in callersVictor Stinner2016-12-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PEP 523 modified PyEval_EvalFrameEx(): it's now an indirection to interp->eval_frame(). Inline the call in performance critical code. Leave PyEval_EvalFrame() unchanged, this function is only kept for backward compatibility.
| | | | | | | * | | | Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-093-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() in various modules when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
| | | | | | | * | | | Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() when the format string only use the format 'O' for objects, like "(O)". _PyObject_CallMethodIdObjArgs() avoids the code to parse a format string and avoids the creation of a temporary tuple.
| | | | | | | * | | | Add _Py_VaBuildStack() functionVictor Stinner2016-12-091-0/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Similar to Py_VaBuildValue(), but work on a C array of PyObject*, instead of creating a tuple.

The compiler might emit more efficient code for i++. Py_ssize_t is the type of a PyTuple index for example. Replace also "int endchar" with "char endchar".

| | | | | | | * | | | Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-054-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

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()
