When a direct or indirect (e.g. on close) flush is called for the file object. _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4263> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
