New submission from Arfrever Frehtes Taifersar Arahesis <arfrever....@gmail.com>:
Python/import.c defines magic word which is used in the beginning of .pyc files to verify if .pyc files have been generated by compatible version of Python. Python 2 supports undocumented -U option increases magic word by 1. Python 3 uses unicode strings by default and doesn't support -U option, but seemingly incorrect change was committed in r55013, which causes that magic word is always increased by 1 in Python 3 in contrary to documentation, which says that it could only happen with some command line options. This problem cannot be fixed in Python 3.1.2 for compatibility with e.g. 3.1.1, but it can be fixed in 3.2. Additionally documentation in 3.1.2 can be fixed. ---------- components: Interpreter Core files: python-3.2-fix_magic_word.patch keywords: patch messages: 96138 nosy: Arfrever, gvanrossum severity: normal status: open title: Magic word incorrect in Python 3 versions: Python 3.1, Python 3.2 Added file: http://bugs.python.org/file15498/python-3.2-fix_magic_word.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7459> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
