根因分析

父 context 被取消(超时、手动 cancel 或 HTTP 客户端断开),worker goroutine 观察到 ctx.Err() == context.Canceled。

English

A parent context was canceled (deadline, manual cancel, or HTTP client disconnect) and the worker goroutine observes ctx.Err() == context.Canceled.

generic

解决方案

  1. 92% 成功率
    Treat context.Canceled as expected and return without error at shutdown:
    
    if errors.Is(err, context.Canceled) {
        return nil
    }
  2. 90% 成功率
    Propagate the context through all calls and check ctx.Err() at loop boundaries.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The context remains canceled; retries fail immediately and waste resources.

  2. 85% 失败

    Leaks the goroutine past shutdown and defeats the purpose of cancellation.
