#28878: Improve deterministic randomness in tests -------------------------+------------------------------------------------- Reporter: asn | Owner: (none) Type: defect | Status: new Priority: Medium | Milestone: Tor: unspecified Component: Core | Version: Tor/Tor | Keywords: wtf-pad, tor-relay, tor-cell, Severity: Normal | padding, tor-tests Actual Points: | Parent ID: #28637 Points: | Reviewer: Sponsor: | -------------------------+------------------------------------------------- As part of test_prob_distr.c in #28142, we implemented a deterministic randomness system for the stochastic tests. There are various things we can improve there:
a) Make it into its own subsystem so that other tests can also use it. b) Don't use a uint32_t counter as the seed, because the byte order is machine dependent. Instead make it a uint8_t[32] or something. c) Allow users to overwrite the seed using environment variables or the CLI. For now users have to tweak the `init_deterministic_rand()` func. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/28878> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
