根因分析

一个 goroutine 在尝试获取一个已被另一个也阻塞的 goroutine 锁定的互斥锁时阻塞，导致死锁。

English

A goroutine is blocked trying to acquire a mutex that is already locked by another goroutine that is also blocked, causing a deadlock.

generic

解决方案

  1. 95% 成功率 
    mu1.Lock(); mu2.Lock(); defer mu1.Unlock(); defer mu2.Unlock()
  2. 85% 成功率 
    if mu.TryLock(time.Second) { defer mu.Unlock() } else { handleTimeout() }

无效尝试

常见但无效的做法:

  1. 70% 失败

    If logic requires same mutex, deadlock persists.

  2. 90% 失败

    Sleep doesn't resolve circular wait.
