根因分析

两个 goroutine 并发访问同一内存位置，且至少有一个是写操作，未使用同步。使用 -race 标志运行时被检测到。

English

Two goroutines accessed the same memory location concurrently, at least one being a write, without synchronization. Detected when running with the -race flag.

解决方案

  1. 95% 成功率 
    var mu sync.Mutex
mu.Lock()
counter++
mu.Unlock()
  2. 90% 成功率 
    var counter int64
atomic.AddInt64(&counter, 1)
n := atomic.LoadInt64(&counter)

无效尝试

常见但无效的做法:

  1. 95% 失败

    The race still exists in production and can cause corrupted data or crashes; the flag only hides detection.

  2. 80% 失败

    Mixing atomic and non-atomic access to the same variable is itself a race and still flagged by the detector.
