使用epoll和非阻塞IO实现单进程回射服务器

Primary LanguageC++

使用epoll和非阻塞IO实现单进程回射服务器

1. 使用

  1. 运行epoll_server

    cd epoll_echo/cmake-build-debug;
./epoll_server

  2. 运行epoll_client

    client也使用epoll来实现IO多路复用，stdin和stdout也被设置为非阻塞，但是epoll_ctl貌似不支持对stdin和stdout进行重定向，所以只能使用如下方式运行client。输入为文件warmDailyReport.php(1000多行)，输出通过tee命令显示到终端同时写入到echo.txt文件。通过ctrl+C结束客户端。

    cd epoll_echo/cmake-build-debug
cat warmDailyReport.php | ./epoll_client | tee echo.txt

  3. 正确性验证

    执行diff命令，查看echo得到的文件与原始文件的区别：

    diif

    通过ctrl+D结束客户端后，socket可以正常断开连接：

    client_terminate

    client输出：
