Merge branch 'master' into vk-api-refactor66 2018-07-13 13:53:21 +01:00
Marc Brinkmann 5336fbe707 Added `RandomAdversary` and the necessary auxiliary functions. 
Random adversaries are created for `broadcast` and `honey_badger`.  Random value generation was added for all type-dependencies of these algorithms, causing the `Rand` trait to be implement for a large portion of the codebase.

Additionally, `MessageWithSender` turned into an actual struct, making it much easier to handle. Tuple-like construction is still available through `MessageWithSender::new()`.

Marc Brinkmann 0e6a8aa272 Fix clippy lints. 
Extra lints have been added in the latest version of clippy; this fixes four instances of two of the new lints.

Vladimir Komendantskiy 7fb1017bb1 changed Step::output to Vec but that didn't fix the dynamic HB test 2018-07-12 21:23:52 +01:00
Andreas Fackler 3f3ac7be13 Minor fixes and simplifications. 
* Clear outdated key gen messages from the buffer.
* Process output after proposing, to make `HoneyBadger` work with a
  single validator.
* Print an error if threshold decryption fails.
* Verify decryption shares with the correct ciphertext.
* Insert all ciphertexts from an epoch at once; otherwise contributions
  can be omitted from a batch.
* Remove `BoolWithFaultLog`: It's easier to return a tuple, and it's
  used only in one place now.
* Avoid redundant signature verification in `VoteCounter`.
* Fix the tests for `QueueingHoneyBadger`.
* Use fewer network sizes to speed up tests a bit.

Andreas Fackler bfab919c76 Add FaultLog::is_empty. 2018-07-12 09:54:26 +02:00

Andreas Fackler 313fe1da75 Extract vote counter from DHB. 2018-07-12 09:54:26 +02:00
c0gent f0ed2e6e12 Make `*HoneyBadger` types thread safe. 
Replaces `Rc` with `Arc`. This allows usage from different threads
which will be necessary for use with Parity.
