Marc Brinkmann d2627272fe Better proptest persistence through deterministic randomness. (#248) ... * Add support for RNG instantiation in proptests. * Use `proptest` module strategy to create the rng for `net_dynamic_honey_badger`. * Use seed generation instead of RNG instantiation in tests. * Remove fixed RNG in `generate_map`. * `VirtualNet` now supports setting the random generator through the builder. * Add missing `time_limit` field to `::std::fmt::Debug` trait implementation on `NetBuilder`. * Pass an instantiated random number generator through `NewNodeInfo` as a convenience. * Make the random number generator of `DynamicHoneyBadgerBuilder` configurable, at the cost of now requiring mutability to call `build_first_node()`. * Ensure RNGs are derive from passed in seed in `net_dynamic_hb` tests. * Correct inappropriate use of `random::Random` instead of `Rng::gen` to generate dependent values in `binary_agreement`. The original implementation used `rand::random()`, which will always use the `thread_rng`, ignoring the fact that an RNG has actually been passed in. * Do not use `OsRng` but passed in RNG instead. * Use reference/non-reference passing of rngs more in line with the `rand` crates conventions. * Document `rng` field on `DynamicHoneyBadger`. * Make `SyncKeyGen` work with the extend (`encrypt_with_rng`) API of `threshold_crypto`. * Use passed-in random number generator in `HoneyBadger`. * Create `SubRng` crate in new `util` module to replace `create_rng()`. * Use an RNG seeded from the configure RNG when reinitializing `DynamicHoneyBadger`. * Use the correct branch of `threshold_crypto` with support for passing RNGs.		2018-10-02 16:24:51 +02:00
