|
|
|
|
BREAKING:
|
|
- genesis file: validator `amount` is now `power`
|
|
- abci: Info, BeginBlock, InitChain all take structs
|
|
- rpc: various changes to match JSONRPC spec (http://www.jsonrpc.org/specification), including breaking ones:
|
|
- requests that previously returned HTTP code 4XX now return 200 with an error code in the JSONRPC.
|
|
- `rpctypes.RPCResponse` uses new `RPCError` type instead of `string`.
|
|
|
|
- cmd: if there is no genesis, exit immediately instead of waiting around for one to show.
|
|
- types: `Signer.Sign` returns an error.
|
|
- state: every validator set change is persisted to disk, which required some changes to the `State` structure.

|
|
- new flag, `--consensus.create_empty_blocks`; when set to false, blocks are only created when there are txs or when the AppHash changes.
|
|
- new config option, `consensus.create_empty_blocks_interval`; an empty block is created after this many seconds.
|
|
- in normal operation, `create_empty_blocks = true` and `create_empty_blocks_interval = 0`, so blocks are being created all the time (as in all previous versions of tendermint). The number of empty blocks can be reduced by increasing `create_empty_blocks_interval` or by setting `create_empty_blocks = false`.
|
|
- new `TxsAvailable()` method added to Mempool that returns a channel which fires when txs are available.
|
|
- new heartbeat message added to consensus reactor to notify peers that a node is waiting for txs before entering propose step.

|
|
|
|

- `--grpc_laddr` is now `--rpc.grpc_laddr`
|
|
- Any configuration option now within a substract must come under that heading in the `config.toml`, for instance:
|
|
```
|
|
[p2p]
|
|
laddr="tcp://1.2.3.4:46656"
|
|
|
|
[consensus]
|
|
timeout_propose=1000
|
|
```
|
|
- Use viper and `DefaultConfig() / TestConfig()` functions to handle defaults, and remove `config/tendermint` and `config/tendermint_test`
|
|
- Change some function and method signatures to
|
|
- Change some [function and method signatures](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) accomodate new config
|
|
|
|
- Logger
|
|
- Replace static `log15` logger with a simple interface, and provide a new implementation using `go-kit`.
|
|
See our new [logging library](https://github.com/tendermint/tmlibs/log) and [blog post](https://tendermint.com/blog/abstracting-the-logger-interface-in-go) for more details
|
|
- Levels `warn` and `notice` are removed (you may need to change them in your `config.toml`!)
|
|
- Change some [function and method signatures](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) to accept a logger
|
|
|
|
- JSON serialization:
|
|
- Replace `[TypeByte, Xxx]` with `{"type": "some-type", "data": Xxx}` in RPC and all `.json` files by using `go-wire/data`. For instance, a public key is now:
|
|
```
|
|
"pub_key": {
|
|
"type": "ed25519",
|
|
"data": "83DDF8775937A4A12A2704269E2729FCFCD491B933C4B0A7FFE37FE41D7760D0"
|
|
}
|
|
```
|
|
- Remove type information about RPC responses, so `[TypeByte, {"jsonrpc": "2.0", ... }]` is now just `{"jsonrpc": "2.0", ... }`
|
|
- Change `[]byte` to `data.Bytes` in all serialized types (for hex encoding)
|
|
- Lowercase the JSON tags in `ValidatorSet` fields
|
|
- Introduce `EventDataInner` for serializing events
|
|
|
|
- Other:
|
|
- Send InitChain message in handshake if `appBlockHeight == 0`
|
|
- Do not include the `Accum` field when computing the validator hash. This makes the ValidatorSetHash unique for a given validator set, rather than changing with every block (as the Accum changes)
|
|
- Unsafe RPC calls are not enabled by default. This includes `/dial_seeds`, and all calls prefixed with `unsafe`. Use the `--rpc.unsafe` flag to enable.
|
|
|
|
|
|
FEATURES:
|
|
|
|
- Per-module log levels. For instance, the new default is `state:info,*:error`, which means the `state` package logs at `info` level, and everything else logs at `error` level
|
|
- Log if a node is validator or not in every consensus round
|
|
- Use ldflags to set git hash as part of the version
|
|
- Ignore `address` and `pub_key` fields in `priv_validator.json` and overwrite them with the values derrived from the `priv_key`
|
|
|
|
IMPROVEMENTS:
|
|
|
|
- Merge `tendermint/go-p2p -> tendermint/tendermint/p2p` and `tendermint/go-rpc -> tendermint/tendermint/rpc/lib`
|
|
- Update paths for grand repo merge:
|
|
- `go-common -> tmlibs/common`
|
|
- `go-data -> go-wire/data`
|
|
- All other `go-` libs, except `go-crypto` and `go-wire`, are merged under `tmlibs`
|
|
- No global loggers (loggers are passed into constructors, or preferably set with a SetLogger method)
|
|
- Return HTTP status codes with errors for RPC responses
|
|
- Limit `/blockchain_info` call to return a maximum of 20 blocks
|
|
- Use `.Wrap()` and `.Unwrap()` instead of eg. `PubKeyS` for `go-crypto` types
|
|
- RPC JSON responses use pretty printing (via `json.MarshalIndent`)
|
|
- Color code different instances of the consensus for tests
|
|
- Isolate viper to `cmd/tendermint/commands` and do not read config from file for tests
|
|

## 0.9.2 (April 26, 2017)
|
|
|
|
BUG FIXES:
|
|
|
|
- Fix bug in `ResetPrivValidator` where we were using the global config and log (causing external consumers, eg. basecoin, to fail).
|
|
|
|
## 0.9.1 (April 21, 2017)
|
|
|
|
FEATURES:
|
|
|
|
- Transaction indexing - txs are indexed by their hash using a simple key-value store; easily extended to more advanced indexers
|
|
- New `/tx?hash=X` endpoint to query for transactions and their DeliverTx result by hash. Optionally returns a proof of the tx's inclusion in the block
|
|
- `tendermint testnet` command initializes files for a testnet
|
|
|
|
IMPROVEMENTS:
|
|
|
|
- CLI now uses Cobra framework
|
|
- TMROOT is now TMHOME (TMROOT will stop working in 0.10.0)
|
|
- `/broadcast_tx_XXX` also returns the Hash (can be used to query for the tx)
|
|
- `/broadcast_tx_commit` also returns the height the block was committed in
|
|
- ABCIResponses struct persisted to disk before calling Commit; makes handshake replay much cleaner
|
|
- WAL uses #ENDHEIGHT instead of #HEIGHT (#HEIGHT will stop working in 0.10.0)
|
|
- Peers included via `--seeds`, under `seeds` in the config, or in `/dial_seeds` are now persistent, and will be reconnected to if the connection breaks
|
|
|
|
BUG FIXES:
|
|
|
|
- Fix bug in fast-sync where we stop syncing after a peer is removed, even if they're re-added later
|
|
- Fix handshake replay to handle validator set changes and results of DeliverTx when we crash after app.Commit but before state.Save()
|
|
|
|
## 0.9.0 (March 6, 2017)
|
|
|
|
BREAKING CHANGES:
|
|
|
|
- Update ABCI to v0.4.0, where Query is now `Query(RequestQuery) ResponseQuery`, enabling precise proofs at particular heights:
|
|
|
|
```
|
|
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;
|
|
}
|
|
```
|
|
|
|
|
|
- `BlockMeta` data type unifies its Hash and PartSetHash under a `BlockID`:
|
|

```
|
|
type BlockMeta struct {
|
|
BlockID BlockID `json:"block_id"` // the block hash and partsethash
|
|
Header *Header `json:"header"` // The block's Header
|
|
}
|
|
```
|
|
|
|
- `ValidatorSet.Proposer` is exposed as a field and persisted with the `State`. Use `GetProposer()` to initialize or update after validator-set changes.
|
|
|
|
- `tendermint gen_validator` command output is now pure JSON
|
|
|
|
FEATURES:
|

- Check peer.Send for failure before updating PeerState in consensus
|
|
- Fix panic in `/dial_seeds` with invalid addresses
|
|
- Fix proposer selection logic in ValidatorSet by taking the address into account in the `accumComparable`
|
|

|
|
- Hex strings in the RPC are now "0x" prefixed
|
|
|
|
|
|
FEATURES:
|
|
|
|
- New message type on the ConsensusReactor, `Maj23Msg`, for peers to alert others they've seen a Maj23,

|
|
## PreHistory
|
|
|
|
Strict versioning only began with the release of v0.7.0, in late summer 2016.
|
|
The project itself began in early summer 2014 and was workable decentralized cryptocurrency software by the end of that year.
|
|
Through the course of 2015, in collaboration with Eris Industries (now Monax Indsutries),
|
|
many additional features were integrated, including an implementation from scratch of the Ethereum Virtual Machine.
|
|
That implementation now forms the heart of [Burrow](https://github.com/hyperledger/burrow).
|
|
In the later half of 2015, the consensus algorithm was upgraded with a more asynchronous design and a more deterministic and robust implementation.
|
|
|
|
By late 2015, frustration with the difficulty of forking a large monolithic stack to create alternative cryptocurrency designs led to the
|
|
invention of the Application Blockchain Interface (ABCI), then called the Tendermint Socket Protocol (TMSP).
|
|
The Ethereum Virtual Machine and various other transaction features were removed, and Tendermint was whittled down to a core consensus engine
|
|
driving an application running in another process.
|
|
The ABCI interface and implementation were iterated on and improved over the course of 2016,
|
|
until versioned history kicked in with v0.7.0.
|
