根因分析

两个或多个协程持有锁并等待彼此释放，导致循环等待条件。

English

Two or more goroutines hold locks and wait for each other to release them, causing a circular wait condition.

generic

解决方案

  1. 95% 成功率 Always lock mutexes in the same order 
    // Lock mu1 then mu2 consistently
mu1.Lock()
mu2.Lock()
// unlock in reverse order
  2. 80% 成功率 Use trylock with a fallback 
    if mu.TryLock() {
    defer mu.Unlock()
    // critical section
} else {
    // handle contention
}

无效尝试

常见但无效的做法:

  1. Use a single global mutex 50% 失败

    A single mutex can cause contention but not deadlock if used correctly; however, if nested locks are needed, it can still deadlock.

  2. Ignore the deadlock and restart the program 90% 失败

    Temporary fix; the deadlock will recur.
