根因分析

在没有对应 Lock() 的情况下调用 mu.Unlock()，常因双重解锁或 defer Unlock 与显式 Unlock 叠加。

English

mu.Unlock() is called without a matching Lock(), often due to a double unlock or an early Unlock in a defer plus explicit Unlock.

解决方案

  1. 95% 成功率 
    mu.Lock()
defer mu.Unlock()
// no other Unlock calls
  2. 93% 成功率 
    func (s *Store) withLock(fn func()) {
    s.mu.Lock()
    defer s.mu.Unlock()
    fn()
}

无效尝试

常见但无效的做法:

  1. 100% 失败

    This is a fatal error; recover cannot catch it.

  2. 75% 失败

    The flag itself needs synchronization and often races.
