STINNER Victor added the comment: Python 3 uses os.urandom() at startup to randomize the hash function. os.urandom() now uses the new Linux getrandom() function which blocks until the Linux kernel is feeded with enough entropy. It's a deliberate choice.
The workaround is simple: set the PYTHONHASHSEED environment variable to use a fixed seed. For example, PYTHONHASHSEED=0 disables hash randomization. If you use virtualization and Linux is not feeded with enough entropy, you have security issues. > I just debugged the adt-virt-qemu failure (...) If you use qemu, you can use virt-rng to provide good entropy to the VM from the host kernel. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26839> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
