Golang Channel Buffer blocking

This is a created article in which the information may have evolved or changed.

Common dual Channel use: C2: = Make (chan int, 2) C2 <-1c2 <-2c2 <-3fmt. Println (<-C2) fmt. Println (<-C2) fmt. Println (<-C2) because the channel size only 2, in the c2<-3 there will be blocked, and then the program has been blocked dead program error: Fatal Error:all Goroutines is asleep-deadlock!

Improved method: 1, increase the size of the Channel 2, synchronous execution to asynchronous execution (because only execute c2<-3 to perform <-C2 data)

Therefore, if there is a big occasion to use the channel, the public management with the pool should pay attention to these blocking problems

C2: = Make (chan int, 2) C2 <-1c2 <-2go func () {C2 <-3} () Fmt. Println (<-C2) fmt. Println (<-C2) fmt. PRINTLN (<-C2) correct execution
