p2p: introduce peerConn to simplify peer creation (#1226)
* expose AuthEnc in the P2P config
if AuthEnc is true, dialed peers must have a node ID in the address and
it must match the persistent pubkey from the secret handshake.
Refs #1157
* fixes after my own review
* fix docs
* fix build failure
```
p2p/pex/pex_reactor_test.go:288:88: cannot use seed.NodeInfo().NetAddress() (type *p2p.NetAddress) as type string in array or slice literal

- [p2p] when `auth_enc` is true, all dialed peers must have a node ID in their address
2018-03-26 12:51:29 -07:00
- [spec] various improvements
- switched from glide to dep internally for package management
2018-03-27 00:06:32 -07:00
- [wire] prep work for upgrading to new go-wire (which is now called go-amino)
p2p: introduce peerConn to simplify peer creation (#1226)
* expose AuthEnc in the P2P config
if AuthEnc is true, dialed peers must have a node ID in the address and
it must match the persistent pubkey from the secret handshake.
Refs #1157
* fixes after my own review
* fix docs
* fix build failure
```
p2p/pex/pex_reactor_test.go:288:88: cannot use seed.NodeInfo().NetAddress() (type *p2p.NetAddress) as type string in array or slice literal
```
* p2p: introduce peerConn to simplify peer creation
* Introduce `peerConn` containing the known fields of `peer`
* `peer` only created in `sw.addPeer` once handshake is complete and NodeInfo is checked
* Eliminates some mutable variables and makes the code flow better
* Simplifies the `newXxxPeer` funcs
* Use ID instead of PubKey where possible.
* SetPubKeyFilter -> SetIDFilter
* nodeInfo.Validate takes ID
* remove peer.PubKey()
* persistent node ids
* fixes from review
* test: use ip_plus_id.sh more
* fix invalid memory panic during fast_sync test
```

- 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.
- p2p: new `p2p.Peer` interface used for all reactor methods (instead of `*p2p.Peer` struct).
2017-09-21 09:34:37 -07:00

## 0.10.3 (August 10, 2017)
2017-07-13 12:09:26 -07:00
FEATURES:
2017-08-09 21:04:07 -07:00
- control over empty block production:
- 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.
- rpc: Add `syncing` field to response returned by `/status` . Is `true` while in fast-sync mode.
IMPROVEMENTS:
- various improvements to documentation and code comments
BUG FIXES:
- mempool: pass height into constructor so it doesn't always start at 0

2017-04-26 17:06:45 -07:00
BREAKING CHANGES:
2017-06-02 20:18:10 -07:00
- Config and Flags:
2017-07-18 03:06:37 -07:00
- The `config` map is replaced with a [`Config` struct ](https://github.com/tendermint/tendermint/blob/master/config/config.go#L11 ),
2017-06-02 20:18:10 -07:00
containing substructs: `BaseConfig` , `P2PConfig` , `MempoolConfig` , `ConsensusConfig` , `RPCConfig`
- This affects the following flags:
- `--seeds` is now `--p2p.seeds`
- `--node_laddr` is now `--p2p.laddr`
- `--pex` is now `--p2p.pex`
- `--skip_upnp` is now `--p2p.skip_upnp`
- `--rpc_laddr` is now `--rpc.laddr`
- `--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:
2017-06-02 20:28:10 -07:00
```
[p2p]
laddr="tcp://1.2.3.4:46656"
2017-07-18 03:06:37 -07:00
2017-06-02 20:28:10 -07:00
[consensus]
timeout_propose=1000
```
- Use viper and `DefaultConfig() / TestConfig()` functions to handle defaults, and remove `config/tendermint` and `config/tendermint_test`
2017-07-18 03:06:37 -07:00
- Change some function and method signatures to
2017-06-02 20:28:10 -07:00
- Change some [function and method signatures ](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b ) accomodate new config
- Logger
2017-07-18 03:06:37 -07:00
- Replace static `log15` logger with a simple interface, and provide a new implementation using `go-kit` .
2017-06-02 20:28:10 -07:00
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
2017-06-02 20:18:10 -07:00
- Levels `warn` and `notice` are removed (you may need to change them in your `config.toml` !)
2017-06-02 20:28:10 -07:00
- Change some [function and method signatures ](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b ) to accept a logger
2017-06-02 20:18:10 -07:00
- 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:
2017-06-02 20:28:10 -07:00
```
"pub_key": {
"type": "ed25519",
"data": "83DDF8775937A4A12A2704269E2729FCFCD491B933C4B0A7FFE37FE41D7760D0"
}
```
2017-06-02 20:18:10 -07:00
- 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
2017-06-02 20:28:10 -07:00
- Introduce `EventDataInner` for serializing events
2017-06-02 20:18:10 -07:00
- 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.
2017-05-16 15:12:56 -07:00
FEATURES:
2017-06-02 20:28:10 -07:00
- 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
2017-05-16 15:12:56 -07:00
- Log if a node is validator or not in every consensus round
- Use ldflags to set git hash as part of the version
2017-06-02 20:18:10 -07:00
- Ignore `address` and `pub_key` fields in `priv_validator.json` and overwrite them with the values derrived from the `priv_key`
2017-05-16 15:12:56 -07:00
2017-04-26 17:06:45 -07:00
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`
2017-06-02 20:18:10 -07:00
- 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)
2017-04-26 17:06:45 -07:00
- Return HTTP status codes with errors for RPC responses
2017-06-02 20:18:10 -07:00
- Limit `/blockchain_info` call to return a maximum of 20 blocks
2017-05-22 05:16:25 -07:00
- Use `.Wrap()` and `.Unwrap()` instead of eg. `PubKeyS` for `go-crypto` types
2017-05-18 03:08:00 -07:00
- RPC JSON responses use pretty printing (via `json.MarshalIndent` )
2017-07-18 03:06:37 -07:00
- Color code different instances of the consensus for tests
2017-06-02 20:18:10 -07:00
- Isolate viper to `cmd/tendermint/commands` and do not read config from file for tests
2017-04-26 17:06:45 -07:00
2017-04-25 21:17:53 -07:00
## 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).
2017-04-21 10:39:02 -07:00
## 0.9.1 (April 21, 2017)
2017-04-18 20:05:46 -07:00
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
2017-04-20 15:22:42 -07:00
- `tendermint testnet` command initializes files for a testnet
2017-04-18 20:05:46 -07:00
IMPROVEMENTS:
- CLI now uses Cobra framework

2017-04-21 08:39:02 -07:00
- `/broadcast_tx_XXX` also returns the Hash (can be used to query for the tx)
2017-04-18 20:05:46 -07:00
- `/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
2017-07-18 03:06:37 -07:00
BUG FIXES:
2017-04-18 20:05:46 -07:00
- 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()
2017-03-06 01:25:55 -08:00
## 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;
2017-07-18 03:06:37 -07:00
bool prove = 4;
2017-03-06 01:25:55 -08:00
}

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
}
```
2017-07-18 03:06:37 -07:00
- `ValidatorSet.Proposer` is exposed as a field and persisted with the `State` . Use `GetProposer()` to initialize or update after validator-set changes.
2017-03-08 22:33:31 -08:00
2017-03-06 01:25:55 -08:00

- Hex strings in the RPC are now "0x" prefixed
FEATURES:
2017-07-18 03:06:37 -07:00
- New message type on the ConsensusReactor, `Maj23Msg` , for peers to alert others they've seen a Maj23,
2017-03-06 01:25:55 -08:00
in order to track and handle conflicting votes intelligently to prevent Byzantine faults from causing halts:
```
type VoteSetMaj23Message struct {

2017-03-08 22:33:31 -08:00
## 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.
2017-07-18 03:06:37 -07:00
Through the course of 2015, in collaboration with Eris Industries (now Monax Indsutries),
2017-03-08 22:33:31 -08:00
many additional features were integrated, including an implementation from scratch of the Ethereum Virtual Machine.
2017-06-18 18:19:59 -07:00
That implementation now forms the heart of [Burrow ](https://github.com/hyperledger/burrow ).
2017-03-08 22:33:31 -08:00
In the later half of 2015, the consensus algorithm was upgraded with a more asynchronous design and a more deterministic and robust implementation.
2017-07-18 03:06:37 -07:00
By late 2015, frustration with the difficulty of forking a large monolithic stack to create alternative cryptocurrency designs led to the
2017-03-08 22:33:31 -08:00
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
2017-07-18 03:06:37 -07:00
driving an application running in another process.
2017-03-08 22:33:31 -08:00
The ABCI interface and implementation were iterated on and improved over the course of 2016,
until versioned history kicked in with v0.7.0.
