New submission from Cheryl Sabella <chek...@gmail.com>: On a Windows 7 system, entering the following:
>>> mime, encoding = mimetypes.guess_type('Untitled.sql') >>> mime 'text\\plain' Meaning, the return value is 'text\\plain' instead of 'text/plain'. Tracking this down, it's due to .sql being loaded from the Windows registry and the registry is using the wrong slash. The mimetypes.guess_type() documentation states: > The return value is a tuple (type, encoding) where type is None if > the > type can’t be guessed (missing or unknown suffix) or a string of > the form 'type/subtype', usable for a MIME content-type header. I don't know if guess_type() (or add_types) should check for a valid types, if .sql should be added to the valid types (it's on the IANA page), or if the documentation should be fixed so it doesn't look like a guarantee. Or all three. :-) ---------- components: Library (Lib) messages: 309275 nosy: csabella priority: normal severity: normal status: open title: mimetypes.guess_type() might be return None or a tuple with (type/subtype, encoding) type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32462> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
