根因分析

对当前未锁定的互斥锁调用 sync.Mutex.Unlock(),通常是由于重复 Unlock 或缺少 Lock。

English

sync.Mutex.Unlock() is called on a mutex that is not currently locked, often due to double Unlock or a missing Lock.

generic

解决方案

  1. 95% 成功率
    Use defer mu.Unlock() immediately after Lock() to ensure pairing:
    mu.Lock()
    defer mu.Unlock()
  2. 85% 成功率
    Review all Lock/Unlock pairs and ensure they are balanced. Consider using sync.RWMutex if read-heavy.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Hides the bug but does not fix the incorrect locking logic; may cause deadlocks later.

  2. 60% 失败

    Channels have different semantics and may not fit the use case; also more complex.
