After recompiliing 3.5 on Windows 10, the two tkinter test cases give the 3.3 TypeErrors instead of crashing. test_tcl also runs. curses does not run on Windows. I do not know enough internals to really understand #15721 or why you call the fix a workaround, but I do understand 'exception' (OK) versus 'crash' (forbidden). Unless you think restoring the previous situation (tp_new = NUll) can cause a worse problem, I would apply this soon, within a week, so not forgotten before the June update releases. The tcl test addition is correct. The fix can be improved later if you think of something better. I initially wondered why _tkinter has classes that cannot be instantiated (from Python). Then I discovered that this is normal, and that the exception is standard. >>> type(iter([]))() Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: cannot create 'list_iterator' instances Is list_iterator.tp_new NULL? Or does it raise instead of crash by other means? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23815> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
