Yury Selivanov added the comment: Please review the attached patch (sig_builtins_01.patch).
Some details: - All parsing code from Signature.from_builtin was moved in a separate helper '_signature_fromstr' - Signature.from_builtin calls '_signature_fromstr'. All its validation logic is untouched. - 'inspect.signature' was tweaked a bit: when it's certain that the object is a class and there is no user-defined __init__ or __new__ or its meta's __call__, it traverses the MRO to find non-empty __text_signature__. If it finds one -- it returns with _signature_fromstr(). If not, it checks if __init__ is type.__init__ or object.__init__. The last check is a bit tricky -- the only way of doing that check (I think) is to use __qualname__. Since the patch is non-trivial, any review/comments would be greatly appreciated. ---------- keywords: +patch Added file: http://bugs.python.org/file33853/sig_builtincls_01.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20473> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
