Multi-Reactor模型中根据角色的不同,可以将Reactor分类两类:mainRactor、subReactor。一般mainReactor是一个,而subReactor会有多个。Multi-Reactor模型的原理如下:1. mainReactor主要负责接收客户端的连接请求,建立新连接,接收完连接后mainReactor就会按照一定的负载均衡策略分发给其中一个subReactor进行管理。 2. subReactor...
Each time a "defer" statement executes, the function value and parameters to the call are evaluated as usual and saved anew but the actual function is not invoked. Instead, deferred functions are invoked immediately before the surrounding function returns, in the reverse order they were deferred....
Of course if your project is more complex, you may create further packages under the project root, and it may have multiple commands (multiple main packages), e.g.:host.com/project/ cmd/ project/ project.go prjtool/ prjtool.go packagex/ x.go packagey/ y.go filea.go fileb.goAn exa...
具体到demo代码:consumer为协程的具体代码,里面是只有一个不断轮询channel变量stop的循环,所以主进程是通过stop来通知子协程何时该结束运行的,在main方法中,close掉stop之后,读取已关闭的channel会立刻返回该channel数据类型的零值,因此子goroutine里的<-stop操作会马上返回,然后退出运行。 事实上,通过channel控制子gorouti...
package main import "fmt" func main() { if num := 9; num < 0 { fmt.Println(num, "is negative") } else if num < 10 { fmt.Println(num, "has 1 digit") } else { fmt.Println(num, "has multiple digits") } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.总结...
Learn how to write functions in Go with simple examples. It is possible to return multiple values from Go functions.

Repeating -r parameters can expose multiple ports: -r format is "local IP: local port @clientHOST:client port". Background: The company computer A provides the web service 80 port and the FTP service 21 port There is one VPS, which public IP is 22.22.22.22 ...
Substantially, what can be done to support multiple c-shared libraries? What's the problem at the root that cannot be solved? If this has been already discussed, please give me a pointer. The underlying problem is that currently each Go runtime assumes it has the complete information of all...
