根因分析

两个 goroutine 并发访问同一内存位置，其中至少一个是写操作，且没有同步；在使用 -race 运行时被检测到。

English

Two goroutines access the same memory location concurrently, at least one is a write, and there is no synchronization; detected when running with -race.

解决方案

  1. 93% 成功率 
    Protect the shared variable with sync/atomic:
atomic.AddInt64(&counter, 1)
v := atomic.LoadInt64(&counter)
  2. 95% 成功率 
    Guard the critical section with a sync.Mutex and keep the section minimal.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Hides the symptom; the race still corrupts data in production and can cause random crashes.

  2. 80% 失败

    Atomic on only one side does not establish a happens-before relationship; the race persists.
