How to deal with deadlock in golang

Deadlock

Deadlock means that during the execution of two or more coroutines, due to competition for resources or due to each other A blocking phenomenon caused by communication. Without external force, they will not be able to advance. (Recommended learning:go)

Common deadlock

Scenario 1: A channel is read and written in a go process

func main() { c:=make(chan int) c<-88 <-c }

Scenario 2: Use the channel before the go process is started

func main() { c:=make(chan int) c<-88 go func() { <-c }() }

Scenario 3: Channel 2 is called in channel 1, and channel 1 is called in channel 2

func main() { c1,c2:=make(chan int),make(chan int) go func() { for { select{ case <-c1: c2<-10 } } }() for { select{ case <-c2: c1<-10 } } }

Deadlocks occur in many situations, but they are all caused by competition for resources and data communication.

The solution to deadlock is to lock.
