问题 Hi I am using a flag when testing in go: file_test.go var ip = flag.String("ip", "noip", "test") I am only using this in one test file. And it works fine when only testing that one test file, but when I run: go test ./... -ip 127.0.0.1 alle of the other test file saying: flag provided but not defined . Have you seen this? Regards 回答1: flag.Parse() is being called before your flag is defined. You have to make sure that all flag definitions happen before calling flag.Parse() , usually by

SpringCloud课程：12.Eureka\Consul\Zookeeper异同

由 左心房为你撑大大i 提交于 2020-12-01 15:42:32
Eureka\Consul\Zookeeper异同 Eureka由于有自我保护机制，属于AP范畴。 组件名 语言 CAP 服务健康检查 对外暴露接口 SpringCloud集成 Eureka Java AP 可配支持 Http 已集成 Consul Go CP 支持 HTTP/DNS 已集成 Zookeeper Java CP 支持 客户端 已集成 CAP理论参考： http://www.ruanyifeng.com/blog/2018/07/cap.html C: Consistency 强一致性 A： Availability 可用性 P: Partition toterance 分区容错性 CAP理论关注粒度是数据，而不是整体系统设计的策略 CAP理论的核心是：一个分布式系统不可能同时满足一致性，可用性和分区容错性这三个需求，因此根据CAP原理将NoSQL数据库分成了满足CA原则，满足CP原则和满足AP原则三大类 CA 单点集群，满足一致性，可用性的系统，通常在可扩展上不太强大 CP 满足一致性，分区容错性的系统，通常性能不是特别高 AP 满足可用性，分区容错性的系统，通常可能对一致性要求低一些。 来源： oschina 链接： https://my.oschina.net/u/1020373/blog/4767804

What is the use of pkg directory in Go?

由 馋奶兔 提交于 2020-12-01 09:08:31
问题 If we have bin directory already where executables go then what is the need of pkg directory? Please explain. 回答1: The pkg directory contains Go package objects compiled from src directory Go source code packages, which are then used, at link time, to create the complete Go executable binary in the bin directory. We can compile a package once, but link that object into many executables. For example, the fmt package appears in almost every Go program. It's compiled once but linked many times,

Go: How to combine two (or more) http.ServeMux?

由 不打扰是莪最后的温柔 提交于 2020-12-01 07:36:06
问题 Given that you have two instances of http.ServeMux , and you wish for them to be served at the same port number, like so: muxA, muxB http.ServeMux //initialise muxA //initialise muxB combinedMux := combineMux([muxA, muxB]) http.ListenAndServe(":8080", combinedMux) How would one go about writing the combinedMux function, as described above? ... or is there an alternative way to accomplish the same thing? 回答1: Because an http.ServeMux is also an http.Handler you can easily nest one mux inside

stdout being buffered in docker container

由 瘦欲@ 提交于 2020-12-01 07:17:29
问题 I'm not entirely sure what is going on here but it appears that stdout is being buffered when I run my code in a container, but not if I run it on the host or on OSX. https://github.com/myles-mcdonnell/procwrap/blob/master/procwrap.go The relevant piece (modified for brevity): cmd := exec.Command("ping", "127.0.0.1") logger := &lumberjack.Logger{ Filename: conf.LogFile, MaxSize: conf.MaxLogSizeMb, MaxBackups: conf.MaxLogBackups, MaxAge: conf.MaxLogAgeDays, } cmd.Stdout = io.MultiWriter(os
