This release finalises our accession to the Hyperledger project and updates our root package namespace to github.com/hyperledger/burrow.
It also includes a bug fix for rpc/V0 so that BroadcastTx can accept any transaction type and various pieces of internal clean-up.
This release was an internal rename to 'Burrow' with some minor other attendant clean up.
This is a consolidation release that fixes various bugs and improves elements of the architecture across the Monax Platform to support a quicker release cadence.
-
pull-510 upgrade consensus engine to Tendermint v0.8.0
-
pull-507 use sha3 for snative addresses for future-proofing
-
pull-506 alignment and consolidation for genesis and config between tooling and chains
-
pull-504 relicense burrow to Apache 2.0
-
pull-500 introduce more strongly types secure native contracts
-
pull-499 introduce word256 and remove dependency on tendermint/go-common
-
pull-493 re-introduce GenesisTime in GenesisDoc
-
Logging system overhauled based on the central logging interface of go-kit log. Configuration lacking in this release but should be in 0.16.1. Allows powerful routing, filtering, and output options for better operations and increasing the observability of a burrow blockchain. More to follow.
-
Genesis making is improved and moved into burrow.
-
Config templating is moved into burrow for better synchronisation of server config between the consumer of it (burrow) and the producers of it (cli and other tools).
-
Some documentation updates in code and in specs.
-
pull-462 Makefile added to capture conventions around building and testing and replicate them across different environments such as continuous integration systems.
- pull-516 Organize and add unit tests for rpc/v0
- pull-453 Fix deserialisation for BroadcastTx on rpc/v0
- pull-476 patch EXTCODESIZE for native contracts as solc ^v0.4 performs a safety check for non-zero contract code
- pull-468 correct specifications for params on unsubscribe on rpc/tendermint
- pull-465 fix divergence from JSON-RPC spec for Response object
- pull-366 correction to circle ci script
- pull-379 more descriptive error message for burrow-client
This release marks the start of burrow as the full permissioned blockchain node of the Monax Platform with the Tendermint permissioned consensus engine. This involved significant refactoring of almost all parts of the code, but provides a solid foundation to build the next generation of advanced permissioned smart contract blockchains.
Many changes are under the hood but here are the main externally visible changes:
-
Features and improvements
- Upgrade to Tendermint 0.6.0 in-process consensus
- Support DELEGATECALL opcode in Ethereum Virtual Machine (important for solidity library calls)
- ARM support
- Docker image size reduced
- Introduction of burrow-client companion library for interacting with burrow
- Improved single configuration file for all components written by eris-cm
- Allow multiple event subscriptions from same host under rpc/tendermint
-
Tool changes
- Use glide instead of godeps for dependencies
-
Testing
- integration tests over simulated RPC calls
- significantly improved unit tests
- the ethereum virtual machine and the consensus engine are now top-level components and are exposed to continuous integration tests
-
Bugfixes (incomplete list)
- [EVM] Fix calculation of child CALL gaslimit (allowing solidity library calls to work properly)
- [RPC/v0] Fix blocking event subscription in transactAndHold (preventing return in Javascript libraries)
- [Blockchain] Fix getBlocks to respect block height cap
