# Changelog ## 0.10.1 (March 22, 2018) FEATURES: - [types] ResponseCheckTx and ResponseDeliverTx are now the same. - [example] `dummy` is duplicated as `kvstore`. IMPROVEMENTS: - glide -> Godep - remove pkg/errors - improve specification.rst ## 0.10.0 (February 20, 2018) BREAKING CHANGES: - [types] Socket messages are length prefixed with real protobuf Varint instead of `` - [types] Drop gogo custom type magic with data.Bytes - [types] Use `[(gogoproto.nullable)=false]` to prefer value over pointer for the types - [types] Field re-ordering ... - [types] KVPair: replace with common.KVPair. Add common KI64Pair too (for fees). - [types] CheckTx/DeliverTx: updates for tags, gas, fees - [types] Commit: Remove code and log from Commit - [types] SetOption: Remove code - [example/dummy] remove dependence on IAVL - [types] IsOk/IsErr: methods removed FEATURES: - [types] SetOption/Query/CheckTx/DeliverTx: Add `info string` field to responses - [types] RequestInitChain.AppStateBytes for app's genesis state IMPROVEMENTS: - [all] remove go-wire and go-crypto dependencies :) ## 0.9.0 (December 28, 2017) BREAKING CHANGES: - [types] Id -> ID - [types] ResponseEndBlock: renamed Diffs field to ValidatorUpdates - [types] changed protobuf field indices for Request and Response oneof types FEATURES: - [types] ResponseEndBlock: added ConsensusParamUpdates BUG FIXES: - [cmd] fix console and batch commands to use a single persistent connection ## 0.8.0 (December 6, 2017) BREAKING CHANGES: - [client] all XxxSync methods now return (ResponseXxx, error) - [types] all methods on Application interface now take RequestXxx and return (ResponseXxx, error). - Except `CheckTx`/`DeliverTx`, which takes a `tx []byte` argument. - Except `Commit`, which takes no arguments. - [types] removed Result and ResultQuery - [types] removed CodeType - only `0 == OK` is defined here, everything else is left to convention at the application level - [types] switched to using `gogo/protobuf` for code generation - [types] use `customtype` feature of `gogo/protobuf` to replace `[]byte` with `data.Bytes` in all generated types :) - this eliminates the need for additional types like ResultQuery - [types] `pubKey` -> `pub_key` - [types] `uint64` -> `int32` for `Header.num_txs` and `PartSetHeader.total` - [types] `uint64` -> `int64` for everything else - [types] ResponseSetOption includes error code - [abci-cli] codes are printed as their number instead of a message, except for `code == 0`, which is still printed as `OK` FEATURES: - [types] ResponseDeliverTx: added `tags` field - [types] ResponseCheckTx: added `gas` and `fee` fields - [types] RequestBeginBlock: added `absent_validators` and `byzantine_validators` fields - [dummy] DeliverTx returns an owner tag and a key tag - [abci-cli] added `log_level` flag to control the logger - [abci-cli] introduce `abci-cli test` command for simple testing of ABCI server implementations via Counter application ## 0.7.1 (November 14, 2017) IMPROVEMENTS: - [cli] added version command BUG FIXES: - [server] fix "Connection error module=abci-server error=EOF" ## 0.7.0 (October 27, 2017) BREAKING CHANGES: - [cli] consolidate example apps under a single `abci-cli` binary IMPROVEMENTS: - [cli] use spf13/cobra instead of urfave/cli - [dummy] use iavl instead of merkleeyes, and add support for historical queries BUG FIXES: - [client] fix deadlock on StopForError ## 0.6.0 (September 22, 2017) BREAKING CHANGES: - [types/client] app.BeginBlock takes RequestBeginBlock - [types/client] app.InitChain takes RequestInitChain - [types/client] app.Info takes RequestInfo IMPROVEMENTS: - various linting ## 0.5.0 (May 18, 2017) BREAKING CHANGES: - `NewSocketClient` and `NewGRPCClient` no longer start the client automatically, and don't return errors. The caller is responsible for running `client.Start()` and checking the error. - `NewSocketServer` and `NewGRPCServer` no longer start the server automatically, and don't return errors. The caller is responsible for running `server.Start()` and checking the error. FEATURES: - [types] new method `func (res Result) IsSameCode(compare Result) bool` checks whether two results have the same code - [types] new methods `func (r *ResponseCheckTx) Result() Result` and `func (r *ResponseDeliverTx) Result() Result` to convert from protobuf types (for control over json serialization) - [types] new method `func (r *ResponseQuery) Result() *ResultQuery` and struct `ResultQuery` to convert from protobuf types (for control over json serializtion) IMPROVEMENTS: - Update imports for new `tmlibs` repository - Use the new logger - [abci-cli] Add flags to the query command for `path`, `height`, and `prove` - [types] use `data.Bytes` and `json` tags in the `Result` struct BUG FIXES: ## 0.4.1 (April 18, 2017) IMPROVEMENTS: - Update dependencies ## 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 ## 0.2.1 (September 12, 2016) IMPROVEMENTS - Better error handling in console ## 0.2.0 (July 23, 2016) BREAKING CHANGES: - Use `oneof` types in protobuf FEATURES: - GRPC support ## PreHistory ##### Mar 26h, 2016 * Introduce BeginBlock ##### Mar 6th, 2016 * Added InitChain, EndBlock ##### Feb 14th, 2016 * s/GetHash/Commit/g * Document Protobuf request/response fields ##### Jan 23th, 2016 * Added CheckTx/Query ABCI message types * Added Result/Log fields to DeliverTx/CheckTx/SetOption * Removed Listener messages * Removed Code from ResponseSetOption and ResponseGetHash * Made examples BigEndian ##### Jan 12th, 2016 * Added "RetCodeBadNonce = 0x06" return code ##### Jan 8th, 2016 * Tendermint/ABCI now comes to consensus on the order first before DeliverTx.
