It turns out a cgi.FieldStorage object may consider itself False even when it has data. This happens when the initialization decided to use read_single() instead of one of the other ways of reading the field value (read_urlencoded() or read_multi()). Then self.list remains None, and __nonzero__ returns False no matter what the contents of self.file is. To make things worse -- or better? -- the Python 3 version still defines __nonzero__() instead of __bool__(). ---------- messages: 198457 nosy: gvanrossum priority: normal severity: normal status: open title: bool(cgi.FieldStorage(...)) may be False unexpectedly versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19097> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
