Merge pull request #138 from poanetwork/afck-builder-change 
Add a `JoinPlan` to facilitate joining a running DHB network.

Vladimir Komendantskiy c779d33dd1 Merge branch 'master' into vk-api-refactor66 2018-07-16 15:16:19 +01:00
Andreas Fackler 1f8373ef93 Add a `JoinPlan` to facilitate joining a running DHB network. 
With that, a node can join a running network as an observer in any epoch
where key generation starts.

Merge pull request #137 from poanetwork/afck-dhb-votes

Merge pull request #133 from poanetwork/mbr-travis-ci-stable 
Tweak CI, now runs stable.
 2018-07-16 10:10:17 +02:00
Marc Brinkmann 3e19b01f1f Tweak CI, now runs stable. 
The following changes have been made to the Travis CI:

* The cache timeout has been increased, before builds would spend three minutes trying to cache something before giving up.
* The toolchain for building and testing has been switched to stable. A nightly version is still used to run `clippy` and `rustfmt`; however in both cases the toolchain binaries are used instead of compiling them from scratch.
* The `cargo check` pass has been removed; it simply tested whether or not the crate compiled against stable before compiling again against release. As there very, very few bugs that will cause a mismatch here (differences will be in execution), a trade-off was made in favor of compiling only once.

Andreas Fackler 55ad2eae44 Fix DHB test with 1 validator; purge key gen msgs. 
This adds a bit of special handling to make sure messages don't stay in
the queue forever in the `dynamic_honey_badger` tests, even if there is
only one validator: the problem was that the single validator is always
ready for input, so it never processed incoming messages. However, to
add the new validator, it needs to process the joining node's key
generation messages.

`DynamicHoneyBadger` now also removes committed key generation messages
from the queue, to avoid committing duplicates.

Merge pull request #112 from poanetwork/mbr--random-adversary-model 
Implement a random adversary
 2018-07-13 13:51:06 +01:00
Marc Brinkmann 591b546402 Removed unnecessary `Hash` where clause. 2018-07-13 13:27:49 +02:00
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()`.
 2018-07-13 13:27:49 +02:00
Marc Brinkmann 510c4478d4 Ensure the adversary is playing fair and give a more helpful error message if they are not. 2018-07-13 13:27:49 +02:00

Fix clippy lints.
 2018-07-13 10:34:07 +01:00
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 92f0602dd7 formatting omission fix 2018-07-12 22:25:44 +01:00
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.

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.

Separate queue from Honey Badger.

Andreas Fackler ca2dd2327e Add back InvalidNodeTransactionSignature fault. 
This was accidentally removed due to a merge conflict.
 2018-07-10 17:29:58 +02:00
Andreas Fackler c1b4381753 Separate queue from Honey Badger. 
This makes Honey Badger a bit more complicated but a lot more flexible:
It is now unaware of transactions and basically just runs one Subset
instance per epoch.

That way, users can use any kind of external queue, control throttling
and prioritization.
