我在多个非缓冲通道上使用select时发现了

select {
case <- chana:
case <- chanb:
}

即使两个通道都有数据,但在处理此选择时,如果chana和case chanb处于不平衡的调用.

package main

import (
    "fmt"
    _ "net/http/pprof"
    "sync"
    "time"
)

func main() {
    chana := make(chan int)
    chanb := make(chan int)

    go func() {
        for i := 0; i < 1000; i++ {
            chana <- 100 * i
        }
    }()

    go func() {
        for i := 0; i < 1000; i++ {
            chanb <- i
        }
    }()

    time.Sleep(time.Microsecond * 300)

    acount := 0
    bcount := 0
    wg := …
