STINNER Victor added the comment: Here is a first patch:
* Add _PyObject_FastCallKeywords(): main entry point * Add _PyCFunction_FastCallKeywords(): implementation for C function, but currently it's just an empty skeleton * Rename fast_function() to PyFunction_FastCallKeywords() and ajust its API In this first implementation, _PyObject_FastCallKeywords() has a full implementation for Python function, otherwise it only uses _PyObject_FastCallDict() fast path if the function has no keyword argument. In the last resort, it creates a temporary tuple and maybe also a temporary dict, to call PyObject_Call(). To test the patch, I modified do_call() to call _PyObject_FastCallKeywords(). I'm not sure that it makes sense in term of performance at this stage. Serhiy: You can use this first implementation to experimental for fast argument parser for keyword arguments passed as (key, value) pairs ;-) ---------- keywords: +patch Added file: http://bugs.python.org/file44191/fastcall_keywords.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27830> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
