kurisu_u

kurisu_u is a modern C++ network library for developing high performance server, supports only TCP protocols and Linux. kurisu_u provides a TCP Server to support multi-threaded and nonblocking IO

Features

High-performance logging with sync and async logging support
LengthCodec to unpack, very similar to netty's LengthFieldBasedFrameDecoder
Supports heartbeat, you can have the server send msg to all clients at the interval you set
ShutdownTimingWheel to shutdown the client connection which don't send msg for the time you set(usually used with heartbeat)

Requires:

GCC >= 7.1(supports C++17 or above)
fmt(will be installed when build kurisu_u)

Before using it you should:

1. Make sure the version of g++ and gcc >= 7.1

Check the g++/gcc version:
$ g++ --version
$ gcc --version

2. Install required packages

Ubuntu:  
$ sudo apt install cmake make
CentOS:  
$ sudo yum install cmake make

Build

build with `cmake`

make sure you are in thr root directory kurisu_u

$ mkdir build && cd build
$ cmake ..
$ make -j$(nproc)
$ sudo make install

Example

The simplest echo server

#include <kurisu/kurisu.h>

int main()
{
    kurisu::EventLoop loop;
    kurisu::TcpServer server(&loop, kurisu::SockAddr(5005), "echo"); //listen port 5005

    server.SetMessageCallback([](const std::shared_ptr<kurisu::TcpConnection>& conn, kurisu::Buffer* buf, kurisu::Timestamp) {
        LOG_INFO << "recv msg:" << buf->ToString();
        conn->Send(buf);
    });

    server.Start();
    loop.Loop();
}

Thanks

Thanks Chen Shuo,kurisu_u is highly inspired by muduo.
Thanks fmt,kurisu_u's time formatting depends on it.
