Nuft

Nuft is an C++17 implementation of the Raft protocol.

Build

Requirement

1. C++17 standard(e.g. g++ 7.2)
2. gRPC
3. Nuke, which is already packed in source
4. gtest(in /usr/local/lib)

Build tests

Build all tests by

make

Run all tests by

./test

Run all tests until failby(This can be used to debug)

python ./src/test/test_until_fail.py

Some tests maybe fail, I will later revise them.

Usage

API

1. NuftResult RaftNode::do_log(const std::string & log_string)
2. NuftResult RaftNode::do_log(raft_messages::LogEntry entry, int command = 0)
3. void RaftNode::run()
4. void RaftNode::run(const std::string & new_name)
5. void RaftNode::stop()
6. void RaftNode::resume()
7. NuftResult RaftNode::do_install_snapshot(IndexID last_included_index, const std::string & state_machine_state)
8. NuftResult RaftNode::update_configuration(const std::vector<std::string> & app, const std::vector<std::string> & rem)
9. std::string RaftNode::get_leader_name() const
10. void safe_leave()
