本文介绍如何打印调用堆栈进行go代码的调试。 打印堆栈使用的runtime package中的Stack()函数 func Stack(buf []byte,all bool) int Stack formats a stack trace of the calling goroutine into buf and returns the number of bytes written to buf. If all is true,Stack formats stack traces of all other goroutines into buf after the trace for the current goroutine. example package main import ( "runtime" "time" "fmt" ) func main() { go power1() for { time.Sleep(time.Duration(1)*time.Minute) } } func power1(){ var buf [1024]byte fmt.Println("power1.....") n := runtime.Stack(buf[:],true) fmt.Println(string(buf[:]),n) } 输出结果: power1..... goroutine 5 [running]: main.power1() /home/lanyang/src/t.go:29 +0xec created by main.main /home/lanyang/src/t.go:14 +0x3c goroutine 1 [sleep]: time.Sleep(0xdf8475800) /home/lanyang/src/t.go:59 +0x107 main.main() /home/lanyang/src/t.go:17 +0x4f 303 以上这篇go 代码的调试---打印调用堆栈的实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持编程小技巧。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
