All notable changes to this module will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[0.0.0.22] - 2023-01-25

  • Add a note on consensus test related workaround related to #462

[0.0.0.21] - 2023-01-24

  • Decouple consensus module and pacemaker module
  • Add pacemaker submodule
  • Update pacemaker struct to remove consensus module field, and related functions
  • Create new pacemaker_consensus.go source file that consists ConsensusPacemaker function implementations

[0.0.0.20] - 2023-01-19

  • Rewrite interface{} to any

[0.0.0.19] - 2023-01-18

  • Remove Block proto definition to consolidate under shared/core/types

[0.0.0.18] - 2023-01-11

Consensus - Core

  • Force consensus to use a "star-like" broadcast instead of "RainTree" broadcast
  • Improve logging throughout through the use of emojis and rewording certain statements
  • Slightly improve the block verification flow (renaming, minor fixes, etc…) to stabilize LocalNet

Consensus - Tests

  • Rename the consensus_tests package to e2e_tests
  • Internalize configuration related to fail_on_extra_msgs from the Makefile to the consensus module
  • Forced all tests to fail if we receive extra unexpected messages and modify tests appropriately
  • After #198, we made tests deterministic but there was a hidden bug that modified how the test utility functions because the clock would not move while we were waiting for messages. This prevented logs from streaming, tests from failing, and other issues. Tend to all related changes.

Consensus - Pacemaker

  • Rename ValidateMessage to ShouldHandleMessage and return a boolean
  • Pass a reason to InterruptRound
  • Improve readability of some parts of the code

[0.0.0.17] - 2023-01-10

  • Updated module constructor to accept a bus and not a runtimeMgr anymore
  • Registering module with the bus via RegisterModule method
  • Updated tests and mocks accordingly

[0.0.0.16] - 2023-01-09

  • Added protobuf message definitions for requests related to sharing state sync metadata and blocks
  • Defined the interface for StateSyncServerModule, StateSyncModule (moving the old interface to StateSyncModuleLEGACY as a reference only)
  • Overhaul (updates, improvements, clarifications & additions) of the State Sync README
  • Removed ValidatorMap() ValidatorMap

[0.0.0.15] - 2023-01-03

  • ValidatorMap uses Actor references now

[0.0.0.14] - 2022-12-21

  • Updated do use the new centralized config and genesis
  • Actor is now a shared struct instead of an interface
  • Removed converters between the interfaces and the consensus structs for Validators

[0.0.0.13] - 2022-12-14

  • Consolidated number of validators in tests in a single constant: numValidators
  • Fixed typo in make test_consensus_concurrent_tests so that we can run the correct test matrix
  • Using GetBus() instead of bus wherever possible
  • LeaderElectionModule's electNextLeaderDeterministicRoundRobin now uses Persistence to access the list of validators instead of the static ValidatorMap.

[0.0.0.12] - 2022-12-12

  • Unexport ConsensusModule fields
  • Create ConsensusDebugModule interface with setter functions to be used only for debugging puroposes
  • Update test in TestPacemakerCatchupSameStepDifferentRounds in pacemaker_test.go to use setter functions

  • Removed unused consensus.UtilityMessage

[0.0.0.10] - 2022-11-30

  • Propagate highPrepareQC if available to the block being created
  • Remove blockProtoBytes from propagation in SetProposalBlock
  • Guarantee that write context is released when refreshing the utility context
  • Use GetBlockHash(height) instead of GetPrevAppHash to be more explicit
  • Use the real quorumCert when preparing a new block

[0.0.0.9] - 2022-11-30

  • Added state sync interfaces and diagrams

[0.0.0.8] - 2022-11-15

  • Propagate the quorumCertificate on Block commit to the Utility module
  • Slightly improved error handling of the utilityContext lifecycle management

[0.0.0.7] - 2022-11-01

  • Removed apphash and txResults from consensusModule structure
  • Modified lifecycle to set the proposal block within a PersistenceContext
  • Allow block and parts to be committed with the persistence context

[0.0.0.6] - 2022-10-12

  • Stores transactions alongside blocks during commit
  • Added current block []TxResult to the module

#235 Config and genesis handling

  • Updated tests and mocks
  • Removed some cross-module dependencies

[0.0.0.5] - 2022-10-06

  • Don't ignore the exit code of m.Run() in the unit tests

[0.0.0.4] - 2022-09-28
