Richard Oudkerk <shibt...@gmail.com> added the comment: Shouldn't test___closure__() also test what happens when the closure is replaced with None, or a tuple which is too long or too short or contains non-cell objects?
All of these things seem to be checked when you create a new function using types.FunctionType: >>> h = types.FunctionType(g.__code__, g.__globals__, "h", g.__defaults__, None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: arg 5 (closure) must be tuple >>> h = types.FunctionType(g.__code__, g.__globals__, "h", g.__defaults__, ()) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: g requires closure of length 2, not 0 >>> h = types.FunctionType(g.__code__, g.__globals__, "h", g.__defaults__, >>> (1,2)) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: arg 5 (closure) expected cell, found int I think the setter should make similar checks. Maybe there is C code which assumes "broken" closures never happen. ---------- nosy: +sbt _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14369> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
