At the time of development, we often encounter scenarios where it is necessary to execute or initialize once, for example, Singleton mode or initialization of the system when it is turned on. General language common practice is to use mutually exclusive operation to set the flag variable, by judging the value of the flag variable to determine whether to execute the relevant code; The implementation of the Golang la

Let's talk about the purpose of Waitgroup: it can wait until all the goroutine execute, and block the execution of the main thread until all the Goroutine execution is complete. Waitgroup a total of three methods: ADD (delta in

This is a creation in Article, where the information may have evolved or changed. Sync.once can control that a function can only be called once and cannot be repeated multiple times. We can implement a thread-safe singleton pattern with the following code package singletonimport ( "fmt" "sync")type object struct { name string}var once sync.Oncevar obj *object //单例指针//公开方法 外包调用func Instance() *object { once.Do(getObj) return obj}func get

This is a creation in Article, where the information may have evolved or changed. Overview Sync/mutex is one of the underlying basic objects of the go language, used to build synchronization logic between multiple goroutine, and is therefore used by a large number of high-level objects.Its working model is similar to the Linux kernel Futex object, the implementation is very concise, performance is guaranteed. Data type Mutex struct { state int32
