spserver 是一个实现了半同步/半异步(Half-Sync/Half-Async)和领导者/追随者(Leader/Follower) 模式的服务器框架，能够简化 TCP server 的开发工作。 spserver 使用 c++ 实现，目前实现了以下功能： 1.封装了 TCP server 中接受连接的功能； 2.使用非阻塞型I/O和事件驱动模型，由主线程负责处理所有 TCP 连接上的数据读取和发送，因此连接数不受线程数的限制； 3.主线程读取到的数据放入队列，由一个线程池处理实际的业务。 4.一个 http 服务器框架，即嵌入式 web 服务器（请参考： SPWebServer：一个基于 SPServer 的 web 服务器框架） -spserver is a realization of a semi-synchronous/semi-asynchronous (Half-Sync/Half-Async) and leader/followers (Leader/Follower) model server framework, to simplify the development of TCP server. spserver use c++ realize now realize the following functions: 1. Packaging the TCP server to accept connections function 2. the use of non-blocking type I/O and event-driven model, by the main thread responsible for handling all TCP connection read and send data, so connections are not thread a few restrictions 3. the main thread to read data Add queue, by a thread pool handle the actual business. 4. A http server framework, that is, embedded web server (p
