In this tutorial you'll create two modules. The first is a library which is intended to be imported by other libraries or applications. The second is a caller application which will use the first. 在本教程中你将创建两个模块。第一个模块是个类库,供其它类库或应用导入。第二个模块是个调用者应...

Modules contain two specific files:go.modandgo.sum. Thego.moddefines the module path and the dependency requirements. Thego.sumis an auto-generated dependencies lock file. Modules allow us to define precise dependency requirements and design reproducible builds for multiple environments. ...
Sourcing multiple modules per repository: Creating a new module Here is the file structure we're going to produce: Let's create a new module. First, we want to create a new, empty directory,greetings, cd into that directory: $ mkdir greetings ...
正如这里和这里所描述的, Go语言原生的map类型并不支持并发读写。concurrent-map提供了一种高性能的解决方案:通过对内部map进行分片,降低锁粒度,从而达到最少的锁等待时间(锁冲突) 在Go 1.9之前,go语言标准库中并没有实现并发map。在Go 1.9中,引入了sync.Map。新的sync.Map与此concurrent-map有几个关键区别。标...
As of the final 1.11 release, the go module cache (used for storing downloaded modules and source code), is in the $GOPATH/pkg/mod location (see the docs here). For clarification, the go build cache (used for storing recent compilation results) is in a different location.This...
