If you write a bug management system and use this PeriodLimit, you can limit each tester to only mention one bug to you every day. Is it much easier to work? 😛 The essential reason for the popularity of microservice architecture today is to reduce the overall complexity of the system and spread the system risks to subsystems, so as to maximiz ...

Students familiar with Python development know that Python has default parameters, so that when instantiating an object, we can selectively override some default parameters as needed to decide how to instantiate the object. When an object has multiple default parameters, this feature is very easy to use and can gracefully simplify the code. Th ...

Welcome to GolangRoadmap, a young GO developer community https://www.golangroadmap.com/ At present, it is an invitation system registration, with registration code: Gopher-1035-0722. It has opened the columns of GO push, GO interview, GO Baodian, GO rebate and so on Go's format printing style is similar to C's printf family, but it is richer ...

Main purpose of this chapter Although the main purpose of this chapter is to optimize time and space, we all know that this is our most troublesome optimization, because various principles and implementation methods are difficult to understand and innovate. Even the schemes proposed by predecessors are still difficult to implement in code or e ...

WaitGroup is a concurrency control method often used in development. Its source code is in Src / sync / WaitGroup In the go file, 1 Structure and 4 methods are defined: WaitGroup {}: structure. state(): the internal method is called in Add() and Wait(). Add(): adds the number of tasks. Done(): completing a task is actually Add(-1). Wait(): blo ...

Several pieces of Go concurrent code You can use go run -- race main Go to verify whether there are concurrency problems in the code for range for i,v := range slice { // ... // go func() ... } In the for range, i and v variables are initialized only once, and the values of i and v will be modified in each round of the for loop. Therefore, ...
