Go Concurrency Patterns: Timing out, moving on  GO并发模式: 超时, 继续前进 23 September 2010 Concurrent programming has its own idioms. A good example is timeouts. Although Go's channels do not support them directly, they are easy to implement. Say we want to…
小结: 1. Background is the root of any Context tree; it is never canceled: 2.     https://blog.golang.org/context Sameer Ajmani29 July 2014 Introduction In Go servers, each incoming request is handled in its own goroutine. Request handlers often start…
https://blog.golang.org/context Introduction In Go servers, each incoming request is handled in its own goroutine. Request handlers often start additional goroutines to access backends such as databases and RPC services. The set of goroutines working…
https://talks.golang.org/2013/advconc.slide#5 It's easy to go, but how to stop? Long-lived programs need to clean up. Let's look at how to write programs that handle communication, periodic events, and cancellation. The core is Go's select statement:…

直接上代码: package main import ( "fmt" "runtime" "strconv" "sync" ) func say(str string) { ; i < ; i++ { runtime.Gosched() fmt.Println(str) } } func sayStat(str string, ch chan int64) { ; i < ; i++ { runtime.Gosch…
Context,是golang用来控制并发流程的库,它能方便的将主控程序的停止信号传递到goroutinue中,从而实现一键中止关联goroutinue的执行,除此之外,它还能将外部变量通过Value的接口传递到goroutinue中.Context是一个接口类型,可以看下面的代码的定义,可以提供一类代表上下文的值,此类型值是并发安全的,也就是说它可以被传播给多个goroutinue. // A Context carries a deadline, cancelation signal, an…
https://blog.golang.org/pipelines https://www.cnblogs.com/junneyang/p/6215785.html 简介 Go语言的并发原语允许开发者以类似于 Unix Pipe 的方式构建数据流水线 (data pipelines),数据流水线能够高效地利用 I/O和多核 CPU 的优势. 本文要讲的就是一些使用流水线的一些例子,流水线的错误处理也是本文的重点. 阅读建议 数据流水线充分利用了多核特性,代码层面是基于 channel 类型 和…
Introducing the Go Race Detector 26 June 2013 Introduction Race conditions are among the most insidious and elusive programming errors. They typically cause erratic and mysterious failures, often long after the code has been deployed to production. W…
