Javascript on Fiber

2. 什么是 fibjs?
• 服务器端 Javascript 开发
• 基于 Google v8 引擎构建
• 完全⾮非阻塞，fiber 驱动，拒绝回调，类似 goroutine
• CommonJS 模块系统
• 80,000+ ⾏行 c/c++ 代码，充分挖掘多核性能
• 27 个基本模块，覆盖常⻅见服务器应⽤用场景

3. 27 个内置模块

5. 更多模块持续发展中

6. fibjs 和 nodejs 有什么不同?

7. 来看⼀一段常⽤用的数据库操作
nodejs fibjs

8. 等⼀一下！！！！！！
nodejs 告诉我们：
会阻塞，导致其他任务不能运⾏行。
写这样的代码难道不会被打吗？

9. nodejs ⼀一直说: sync 是邪恶的

10. 祂们说：
In busy processes, the programmer is strongly
encouraged to use the asynchronous versions of these
calls. The synchronous versions will block the entire
process until they complete--halting all connections.

11. ⽽而 module.js ⾥里华丽丽滴写着这样的代码

12. 因此 nodejs 在 require 时不响应请求

13. fibjs 不会出现这样的尴尬
当调⽤用阻塞⽅方法时，
fibjs 会保护现场，挂起当前
fiber，并将 Javascript 引擎切
换⾄至下⼀一个排队的 fiber。挂起
的 fiber 在⼯工作完成后会进⼊入
排队队列等待恢复

14. fibjs 有三种类型的线程(nodejs 类似)
Javascript 线程⼯工作线程池异步 io 线程

15. Javascript 线程是 fibjs 的主线程
Javascript 线程• ⼀一个 fibjs 进程只有⼀一个 Javascript 线程
• Javascript 线程内会运⾏行多个 fiber
• Javascript 代码在 fiber 内运⾏行
• 同⼀一时刻只会有⼀一个 fiber 激活
• 当前 fiber 休眠时其它 fiber 才会恢复
• fiber 不释放就会把 Javascript 塞住

16. socket 操作会委托给异步 io 线程处理
Javascript 线程异步 io 线程
sock.recv
return

17. 阻塞操作也会委托给⼯工作线程池处理
Javascript 线程⼯工作线程池
fs.readFile
return

18. 最终避免 fiber 阻塞导致 Javascript 被挂起

19. fibjs 的并发：轻量的⽤用户空间线程 fiber
• 操作系统线程的切换成本昂贵
• fiber 是在应⽤用级的线程系统
• 运⾏行现场完整保护，对应⽤用开发透明
• 可以直接使⽤用的编程逻辑，包括 try/catch
• 基于堆栈切换现场，模块调⽤用和返回更⾼高效
• ⾮非抢先，⽆无需内存级锁，并发逻辑简单

20. 再回顾⼀一下这两段代码，是不是很爽
nodejs fibjs

21. nodejs 常说: 使⽤用回调，所以更快?

22. 祂们⽤用 Apache 和 nginx 的对⽐比来证明

23. ⽽而事实上，异步并不等同于回调

24. 这是⼀一个 web 服务器基准测试

并发连接

25. 平均 7.25 倍

26. 有⺴⽹网友祭出 cluster ⼤大法

27. 但是 fibjs 真的是多线程吗?

28. fibjs 同样是单线程的
• fibjs 和 nodejs 都是以 v8 为脚本引擎
• v8 本⾝身被设计为 isolate 不⽀支持多线程
• nodejs 使⽤用异步回调复⽤用 v8 线程
• fibjs 使⽤用 fiber 复⽤用 v8 线程
• 因此 fibjs 和 nodejs 都是单线程

29. 那么 fibjs 快在哪⾥里呢?

30. Javascript 线程是珍贵的计算资源
Javascript 线程

31. fibjs 将更多的计算移⾄至⼯工作线程池
Javascript 线程⼯工作线程池异步 io 线程

32. ⼯工作线程不再仅仅完成阻塞操作
⼯工作线程池
• 同步 io 操作，⽐比如磁盘操作，⽂文件处理
• 计算密集的⽅方法，⽐比如加密，压缩，图像
• 异步 io 基础上的复杂逻辑，⽐比如协议处理
ps: 异步 io 基础上的计算，全部以异步⽅方式完成，并
发性能更⾼高。

33. 从⽽而提⾼高 Javascript 线程利⽤用率
Javascript 线程Javascript 线程

34. 多线程的⼯工作线程池也可以发挥多核性能
Javascript 线程⼯工作线程池异步 io 线程

35. fibjs 是更彻底的异步
并将异步延伸⾄至⼯工作线程池
只是不在 js 层表现出来

36. fibjs 的应⽤用逻辑是在太过于直⽩白和简单
毫⽆无 nodejs 回调处理的各种惊艳技巧
就不再展⽰示那些毫⽆无趣味的⽰示例代码了
