Antoine Pitrou <pit...@free.fr> added the comment: One observation is that when the -W option is used, the "warnings" module gets loaded very early and itself imports linecache which then imports tokenize. At this point, the standard IO streams have not been initialized (_io is imported later) and the builtin "open" may not exist at all. So when tokenize references "open", it is a NameError at that point (which explains why the "weird fix" above is actually correct).
As an additional annoyance, when importing Lib/warnings.py fails (for example if you sneak in a "1/0" at the beginning of the file), the exception gets silenced: the NameError above doesn't get printed. ---------- nosy: +benjamin.peterson, brett.cannon _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10372> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
