Changelog

0.4.0 (March 6, 2017)

BREAKING CHANGES:

  • Query takes RequestQuery and returns ResponseQuery. The request is split into data and path, can specify a height to query the state from, and whether or not the response should come with a proof. The response returns the corresponding key-value pair, with proof if requested.
message RequestQuery{
	bytes data = 1;
	string path = 2;
	uint64 height = 3;
	bool prove = 4; 
}

message ResponseQuery{
	CodeType          code        = 1;
	int64             index       = 2;
	bytes             key         = 3;
	bytes             value       = 4;
	bytes             proof       = 5;
	uint64            height      = 6;
	string            log         = 7;
}

IMPROVEMENTS:

  • Updates to Makefile
  • Various cleanup
  • BaseApplication can be embedded by new apps to avoid implementing empty methods
  • Drop BlockchainAware and make BeginBlock/EndBlock part of the type Application interface

0.3.0 (January 12, 2017)

BREAKING CHANGES:

  • TMSP is now ABCI (Application/Asynchronous/A BlockChain Interface or Atomic BroadCast Interface)
  • AppendTx is now DeliverTx (conforms to the literature)
  • BeginBlock takes a Header:
message RequestBeginBlock{
	bytes hash = 1;
	Header header = 2;
}
  • Info returns a ResponseInfo, containing last block height and app hash:
message ResponseInfo {
	string data = 1;
	string version = 2;
	uint64 last_block_height = 3;
	bytes last_block_app_hash = 4;
}
  • EndBlock returns a ResponseEndBlock, containing the changed validators:
message ResponseEndBlock{
	repeated Validator diffs = 4;
}
  • Hex strings are 0x-prefixed in the CLI
  • Query on the Dummy app now uses hex-strings

FEATURES:

  • New app, PersistentDummy, uses Info/BeginBlock to recover from failures and supports validator set changes
  • New message types for blockchain data:
//----------------------------------------
// Blockchain Types

message Header {
	string chain_id = 1;
	uint64 height = 2;
	uint64 time = 3;
	uint64 num_txs = 4;
	BlockID last_block_id = 5;
	bytes last_commit_hash = 6;
	bytes data_hash = 7;
	bytes validators_hash = 8;
	bytes app_hash = 9; 
}

message BlockID {
	bytes hash = 1;
	PartSetHeader parts = 2;
}

message PartSetHeader {
	uint64 total = 1;
	bytes hash = 2;
}

message Validator {
            bytes             pubKey      = 1;
            uint64            power       = 2;
}
  • Add support for Query to Counter app

IMPROVEMENT:

  • Don't exit the tmsp-cli console on bad args

BUG FIXES:

  • Fix parsing in the Counter app to handle invalid transactions
