根因分析

上下文被取消（父级取消、超时或客户端断开），而下游操作正在进行。任何感知上下文的调用都会返回此错误。

English

A context was canceled (parent cancel, timeout, or client disconnect) while a downstream operation was in flight. The error surfaces from any context-aware call.

generic

解决方案

  1. 90% 成功率 
    if errors.Is(err, context.Canceled) {
    return nil // expected on shutdown
}
  2. 88% 成功率 
    if errors.Is(err, context.DeadlineExceeded) { retry() }
if errors.Is(err, context.Canceled) { return err }

无效尝试

常见但无效的做法:

  1. 85% 失败

    Retrying with the same canceled context fails instantly in a tight loop; burns CPU and logs.

  2. 80% 失败

    Removes timeout propagation; leaked requests and shutdown hangs.
