深入Go并发编程研讨课

深入Go并发编程研讨课

企业级的并发库: gofer

Go提供了我们便利的进行并发编程的工具、方法和同步原语,同时也提供给我们诸多的犯错的机会,也就是俗称的“坑”。即使是顶级Go开发的项目,比如Docker、Kubernetes、gRPC、etcd, 都是有经验丰富的Go开发专家所开发,也踩过不少的并发的坑,而且依然源源不断的继续踩着,即便是标准库也是这样。(参考

分析和总结并发编程中的陷阱,避免重复踩在别人的坑中,正式本次培训课的重要内容。只有深入了解并发原语的实现,全面了解它们的特性和限制场景,注意它们的局限和容易踩的坑,才能提高我们的并发编程的能力。通过了解和学习其他人的经验和贡献的项目和库,我们可以更好的扩展我们的视野,避免重复的造轮子,或者说我们可以制作更好的轮子。

语言的内存模型定义了对变量的读写的可见性,可以清晰而准确读写事件的happen before关系。对于我们,可以很好地分析和编排goroutine的运行,避免数据的竞争和不一致的问题。

通过本次课程,你可以:

  • 了解基本同步原语的具体实现、hack同步原语进行扩展,了解它们的使用场景和坑,已经别人是怎么踩的
  • 了解一些扩展的同步源于,对于标准库sync包的补充
  • 对于规模很大的项目,分布式同步原语是必不可少的,带你了解便利的分布式同步原语
  • atomic可以保证对数据操作的一致性,利用CAS可以设计lock-free的数据结构
  • channel是Go语言进行并发编程的很好的工具,带你了解它的使用姿势
  • 了解Go语言的内存模型
