解决方案

  1. 80% 成功率
    _, err := io.Copy(dst, src); if err != nil { if errors.Is(err, syscall.EPIPE) { /* handle gracefully */ } else { log.Fatal(err) } }

无效尝试

常见但无效的做法:

  1. 90% 失败

    The pipe remains broken; retries will fail repeatedly.

  2. 85% 失败

    May hide critical I/O issues and lead to data loss.
