异步多线程C/S框架gko_pool

曾经在上家公司做了一个内网P2P的传输工具名曰gingko 当时太菜了,网络部分写的很差,各种阻塞式网络通信 后来离职把memcached的代码研究了一下,感觉里面的网络模型非常先进 我就把memcached的网络部分抽取出来和gingko做了结合,写成了一个网络框架叫gko_pool 大致特性是:

  • 完全异步化(包括DNS解析)
  • 可以listen一个端口当server,也可以主动发起连接写client
  • worker是对等的多线程
  • 内置一个简单的“内存池”

看代码发现memcached状态机有个逻辑上的bug 顺手给memcached提了个patch 后来这事就被淡忘了,过了两年被维护者发现合到master上了,维护者是这么说的:

Wow, two years old... and it looks correct to me. If that update_event fails the connection might zombie. It‘s very hard for that to fail and it‘s been that way forever. Pushed a commit for the next release.

言归正传,可以毫不夸张的说memecached是多线程异步网络编程的一个丰碑(nginx是多进程异步网络编程的一个丰碑) 我就把memcached的网络部分抽取出来写成了一个网络框架叫gko_pool https://github.com/auxten/gko_pool

 

举个栗子:http刷票器,在我的笔记本虚机上也能达到300KQPS,控制了一下速度,一不小心就把sina的服务器打挂了

我为了刷票刷的真实,还写了这么多UserAgent,刷票界的良心啊,哈哈哈 更多例子,比如:一个自定义协议的client、server等请移步github 这套库的稳定性大家不用质疑,已经用在了我现在公司的上万台服务器的很多网络Daemon上
