根因分析

English

A goroutine panics due to nil pointer dereference, and the panic is recovered but the goroutine may have corrupted state.

解决方案

  1. 95% 成功率 
    if p != nil { p.Method() } else { handleError() }
  2. 85% 成功率 
    defer func() { if r := recover(); r != nil { log.Println(r) } }()

无效尝试

常见但无效的做法:

  1. 80% 失败

    Recover doesn't fix root cause; nil pointer remains undetected.

  2. 90% 失败

    Race condition not solved by timing.
