David M. Beazley <beaz...@users.sourceforge.net> added the comment: Placing a note in the standard library documentation would be a start. Just say in Python 3.0 it always returns the result as an unsigned integer whereas in Python 2.6 a 32-bit signed integer is returned. Although the numerical value may differ between versions, the underlying bits are the same. Use crc32() & 0xffffffff to get a consistent value (already noted).
Note: Not everyone uses checksums in only a packed-binary format. Having the integer value just change across Python versions like that is a real subtle compatibility problem to point out. _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4903> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
