根因分析

多个 goroutine 在无同步的情况下读写共享变量，race detector 报告了冲突访问。

English

Multiple goroutines read and write a shared variable without synchronization. The race detector reports the conflicting accesses.

解决方案

  1. 95% 成功率 
    var counter int64
atomic.AddInt64(&counter, 1)
  2. 93% 成功率 
    var mu sync.Mutex
mu.Lock()
counter++
mu.Unlock()

无效尝试

常见但无效的做法:

  1. 90% 失败

    Hides the symptom but the underlying race still corrupts data and can crash in production.

  2. 85% 失败

    unsafe does not provide synchronization; the race remains.
