根因分析

上下文被取消，但 goroutine 未检查上下文并尝试使用它，导致恐慌或错误。

English

A context is canceled, but a goroutine doesn't check the context and tries to use it, causing a panic or error.

解决方案

  1. 90% 成功率 
    Check ctx.Err() before and after operations, and return early if canceled.
  2. 95% 成功率 
    Pass ctx to all functions and use select with ctx.Done() to handle cancellation.

无效尝试

常见但无效的做法:

  1. 80% 失败

    May lead to resource leaks or incorrect results; cancellation should be respected.

  2. 60% 失败

    Loses cancellation ability; may cause indefinite blocking.
