v0.23.1 - 2019-05-05

Fix the issue about showing the wrong version. Check the details at [#538]

v0.23.0 - 2019-04-26

Upgrade Note

In v0.23.0, CITA upgraded the P2P discovery protocol, which leads to Incompatibility with v0.22.0. So the nodes with CITA v0.23.0 and the nodes with CITA v0.22.0 cannot discover each other in the network. Therefore, when upgrading, all nodes in the network need to be upgraded to v0.23.0 at the same time.

Following Upgrade Instructions to upgrade the nodes.

New Feature Description

The v0.23.0 version added two RPC interfaces:

curl -X POST --data '{"jsonrpc":"2.0","method":"getVersion","params":[],"id":83}'
curl -X POST --data '{"jsonrpc":"2.0","method":"peersInfo","params":[],"id":83}'

v0.22.0 - 2019-03-29

Upgrade Note

The v0.22.0 version of the node configurations is compatible with the v0.21 version. Means that you can run v0.22.0 directly using the v0.21 node configurations. However, due to the refactoring of the network, the nodes executed with v0.22.0 are incompatible with the original nodes (they have different node discovery and transfer protocols), so all nodes need to be upgraded to v0.22.0 at the same time.

Following Upgrade Instructions to upgrade the nodes.

New Feature Description

The new feature of integrating p2p to network service, we add discovery of the network node when the original configuration is compatible. But we still need to make some changes to the network configuration file definition:

The old version network.toml looks like:

port = 4000
enable_tls = true
id_card = 9
[[peers]]
    ip = "127.0.0.1"
    port = 4001
    common_name = "test1.cita"
[[peers]]
    ip = "127.0.0.1"
    port = 4002

In the version of v0.22.0, we will discard the item id_card and common_name.

In the old version, when a new node is added to the network, we need to change the item [[peers]] in all nodes' network.toml to reconstruct the network. It is a very complicated operation. But in v0.22.0, the item [[peers]] means known nodes in the network, you can set only one [[peers]], then it can discovery all the network nodes through a discovery protocol.

Framework

  • [Optimization] Replace std channel with crossbeam channel. @kaikai1024 @leeyr338
  • [Optimization] Reconfigure the parameters of rocksdb, and this can greatly reduce the .sst files in the database. @jerry-yu

Executor

Auth

  • [Fix] Auth crashes when it is not ready. @leeyr338

Network

  • [Feature] The network service is refactored by using the p2p protocol. @leeyr338

Consensus

  • [Fix] Consensus goes into panic when timer min peek is extremely close to Instant::now(). @KaoImin

RPC

Scripts

  • [Optimization] Format Python codes. @ouwenkg

Doc

  • [Doc] Update Rust SDK info in readme. @u2
  • [Doc] More info about automatic execution. @wangfh666
  • [Doc] Fix start cita command in log management. @77liyan

v0.21.1 - 2019-03-15

Fix the issue about high CPU usage caused by too many sst files. Check the details at #206

v0.20.3 - 2019-03-11

Fix the issue about high CPU usage caused by too many sst files. Check the details at #206

v0.21.0 - 2019-02-19

Upgrade Note

Older version upgrades the v0.21 version requires node configuration modifications.

  • Adding the following three configurations in each node's executor.toml

The old version executor.toml:

Journaldb_type = "archive"
Prooftype = 2
Grpc_port = 5000

The new version executor.toml:

Journaldb_type = "archive"
Prooftype = 2
Grpc_port = 5000
Genesis_path = "./genesis.json"
Statedb_cache_size = 5242880
Eth_compatibility = false
  • Modifying cita-execuror configuration item in each node's forever.toml:

The old version forever.toml:

[[process]]
Name = "cita-executor"
Command = "cita-executor"
Args = ["-g","genesis.json","-c","executor.toml"]
Pidfile = ".cita-executor.pid"
Respawn = 3

The new version forever.toml:

[[process]]
Name = "cita-executor"
Command = "cita-executor"
Args = ["-c","executor.toml"]
Pidfile = ".cita-executor.pid"
Respawn = 3

After completing the above modifications, following Upgrade Instructions.

Fix the bug of version 0.19 that ordinary nodes can't sync blocks from the consensus nodes with a special situation.

Check the details at #201.

v0.20.2 - 2018-11-27

Fixed a bug that getting blockhash in solidity contract will get uncertain result.

pragma solidity ^0.4.24;
contract Test {

    • Stop all the nodes;
    • Upgrade all the nodes;
