根因分析

所有 goroutine 都阻塞在 channel 或锁上，无法继续推进，Go 运行时死锁检测器触发。

English

All goroutines are blocked waiting on channels/locks with no possibility of progress; the Go runtime deadlock detector fires.

解决方案

  1. 95% 成功率 
    ch := make(chan int, 1)
ch <- 1 // no receiver needed for buffered channel
  2. 90% 成功率 
    select {
case v := <-ch:
    _ = v
case <-time.After(time.Second):
    return errors.New("timeout")
}

无效尝试

常见但无效的做法:

  1. 90% 失败

    Sleep does not unblock the sender; the deadlock detector still fires once all goroutines park.

  2. 95% 失败

    fatal error from the runtime is not recoverable via recover(); it calls exit directly.
