根因分析

竞态检测器（go test -race / go run -race）观察到两个 goroutine 并发访问同一内存位置，至少一个是写操作，且没有同步。

English

The race detector (go test -race / go run -race) observed two goroutines accessing the same memory location concurrently, at least one being a write, without synchronization.

解决方案

  1. 92% 成功率 
    Introduce sync.Mutex or sync/atomic around the shared variable; ensure happens-before via channel send/receive.
  2. 88% 成功率 
    Pass data by value into goroutines or use immutable snapshots; run go test -race in CI to prevent regressions.

无效尝试

常见但无效的做法:

  1. 95% 失败

    The race still corrupts data in production; hiding it makes failures nondeterministic and worse.

  2. 90% 失败

    Sleeps reduce detection probability but do not establish a happens-before relationship.
