根因分析

任何 goroutine 中未恢复的 panic 都会终止整个程序。与其他一些语言不同，Go 不会隔离 goroutine 的 panic。

English

An unrecovered panic in any goroutine terminates the entire program. Unlike some languages, Go does not isolate goroutine panics.

解决方案

  1. 90% 成功率 
    Add 'defer func(){ recover() }()' as the first statement inside every goroutine
  2. 85% 成功率 
    Use errgroup and convert panics to errors via a recover wrapper around each task

无效尝试

常见但无效的做法:

  1. 85% 失败

    Sub-goroutine panics still escape and crash the process

  2. 95% 失败

    init runs in the main goroutine; cannot catch other goroutines
