New submission from Christian Heimes <li...@cheimes.de>: All proposed fixes for a randomized hashing function raise and fall with a good random number generator to feed the random seed. The seed must be created very early in the startup phase of the interpreter, preferable before the basic types are initialized. CPython already have multiple sources for random data (win32_urandom in Modules/posixmodule.c, urandom in Lib/os.py, Mersenne twister in Modules/_randommodule.c). However we can't use them because they are wrapped inside Python modules which require infrastructure like initialized base types.
Discussion at http://mail.python.org/pipermail/python-dev/2012-January/115263.html My proposed changes are implemented in my feature fork but not yet well tested. Windows build files needs modification, too. ---------- assignee: christian.heimes hgrepos: 98 messages: 150527 nosy: barry, benjamin.peterson, christian.heimes, georg.brandl, gvanrossum, pitrou priority: release blocker severity: normal stage: patch review status: open title: Random number generator in Python core type: enhancement versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13704> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
