[issue6504] infinite recursion from calling builtins.open()

Antoine Pitrou added the comment: Yes, we conditionally import the "locale" module in order to guess the encoding when it is not specified by the caller. We can't import it at module initialization time because it would cause bootstrapping issues. The Python equivalent of the logic expressed in

kai zhu added the comment: current hack-around, then is to pre-import locale, which is verified to work: # beg test.py class importer(object): def find_module(self, mname, path = None): open("foo.txt") import sys, locale; sys.meta_path.append(importer) import collections # no recursion # end

Georg Brandl added the comment: First, the second bug isn't a bug since that restriction has been lifted in Python 3. The original issue occurs because open() for text modes imports the "locale" module. This is kind of nasty, because calling open() is well within what a find_module() implementa

kai zhu added the comment: recursion also goes away if we open as raw bytes: open("foo.txt", "rb"). modes "r+" & "w" also give infinite recursion, while "rb+" & "wb" do not. note found another bug: instance method find_module should raise exception anyway, since its class was uninstantiated i
