Primary LanguageC++

C++11基于协程和reactor的高性能Linux服务器框架

特征

  • 实现了协程，以及协程调度模块，且在其之上实现了高性能Linux服务器框架
  • 实现了基于多线程的reactor两种模型的高性能Linux服务器框架
  • 实现了现代版的C++11接口，利用C++11新的特性
  • 在协程模式中能够用同步的方式表现出异步的特性，简化编码的逻辑
  • 封装了spdlog库，更加方便高效地利用高性能日志
  • 封装了mysql C api，使得mysql使用更加简单
  • 实现了可自动扩容、任务盗取的线程池
  • 利用最小堆和timerfd实现了定时器以及实现了基于时间轮的定时器
  • hook了系统底层和socket相关的API、socket io相关的API等
