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()`.

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
Vladimir Komendantskiy 1254d40147 fixed a starvation issue in Agreement when num_faulty=0 2018-07-12 15:12:06 +01:00
Vladimir Komendantskiy 0ba06fdb76 added step output in DistAlgorithm 2018-07-12 14:54:05 +01:00
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.

Peter van Nostrand 6783ece9b0 Added faulty node logging to algorithms. 2018-07-09 13:45:11 -04:00

Andreas Fackler 2db67df325 Rename is_full_node to is_peer. 2018-06-26 10:57:44 +02:00
Andreas Fackler 2a5f9f1bfe Allow observer nodes in all algorithms. 
This allows nodes to join the network without sending any messages
themselves. They can't give any input and just observe the outcome.

Closes #81

Vladimir Komendantskiy 7a4fc37628 implemented an optimistic random common coin schedule 2018-06-22 10:39:55 +01:00
Andreas Fackler 83f8d61402 Support serde by default. 
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
 2018-06-20 10:21:52 +02:00
Andreas Fackler 66f396e01c Remove more NodeUid trait bounds. 
Use a `BTreeMap` instead of `HashMap` in `NetworkInfo`. The number of
nodes can't grow very large anyway.

Andreas Fackler 3f707a8e12 Return proposer info from HoneyBadger. 
Also, consistently name generic arguments, and remove some unused trait
bounds.

Vladimir Komendantskiy c38aad2c0a Refactored the comms from the consensus node module 
I reduced the socket IO tasks to mere message forwarders. The algorithm
complexity lies in stage modules. Example: broadcast/mod.rs. Communication is
set up and modules are run from the node module.

There is a problem with this commit. std:🧵:spawn imposes a static
lifetime guarantee on type T in Message<T>.
