golang并发底层实现竟然都是它!!! 《手摸手系列》把go sync包中的并发组件已经写完了,本文作为完结篇,最后再来探讨下go运行时锁的实现。记得在《手摸手Go 并发编程的基建Semaphore》那篇中我们聊过sync.Mutex最终是依赖sema.go中实现的sleep和wakeup原语来实现的。如果细心的小伙伴会发现: 代码语言:javascript 代码...
AI代码解释 // cancelCtx是可取消的Context, 当它被取消的时候,它的孩子cancelCtx也都会被取消,也就是级联取消type cancelCtx struct{Context// 互斥锁字段,保护下面字段,防止存在data racemu sync.Mutex// protects following fields// done表示是否取消标记,当done被取消,也就是close(done)之后,调用cancelCtx.Do...
The release focuses primarily on implementation work, improving the garbage collector and preparing the ground for a fully concurrent collector to be rolled out in the next few releases. Stacks are now contiguous, reallocated when necessary rather than linking on new “segments”; this release theref...
