golang debug调试

1. debug by gdb:

office doc

 download the runtime-gdb file.

$ wget -q -O - https://golang.org/src/runtime/runtime-gdb.py  |grep '//g" -e "s/

//g" -e "s/^\t//g" -e 's/"/"/g' -e "s/'/'/g" -e "s/>/>/g" -e "s/</ 
   
linux 下应该有脱字符处理工具(iconv)。　或者wget 本身应该能处理掉脱字符。
 
   
 
 
   
run gdb by: 
 
   
$ $GOROOT=`go env  |grep GOROOT |cut -d "=" -f2`
 
   
$ gdb your_bin -d $GOROOT
 
   
$ gdb cpuinfo_main -d `go env  |grep GOROOT |cut -d "=" -f2`
 
   
source ~/go/src/runtime/runtime-gdb.py
 
   
中文参考
 
   
 发现最新的golang1.6已经自带了runtime-gdb.py
 
   
进入gdb
 
   
(gdb) add-auto-load-safe-path /usr/local/go/src/runtime/runtime-gdb.py
 
   
echo "set auto-load safe-path /" > line to your configuration file "/home/shaohef//.gdbinit".
 
   
直接运行
 
   
$ gdb your_bin 
 
   
２．　godebug
 
   
http://studygolang.com/articles/2899
 
   
Download:
 
   
$ go get -u github.com/mailgun/godebug
 
   
将　_ = "breakpoint"　插入代码。
 
   
 
     
     
    
 
     
 1 package main
 2 
 3 import (
 4     "fmt"
 5 )
 6 
 7 func main() {
 8     _ = "breakpoint"
 9     fmt.Print("**********************\n")
10 }
 
    
 
    View Code 
   
 
   
build godbug
 
   
$ go build 
 
   
mv  godbug to goroot bin
 
   
$ sudo cp godebug /usr/local/go/bin/
 
   
$ debug
 
   
godbug run your go_file.
 
   
3.  Go语言debug调试

4. 采用idea IDE环境。

5. 使用Delve进行Golang代码的调试
 
   
http://www.qingpingshan.com/jb/go/111271.html
 
   
 
    
$ dlv  exec  ./sample-controller -- -kubeconfig=$HOME/.kube/config
 
   
 
   
使用Delve调试test case
 
   
dlv test --build-flags='github.com/dlsniper/u/tmp/mypack' -- -test.run ^TestHello$

https://github.com/derekparker/delve/issues/422
 
   
6. 代码中打印栈信息
 
   
 
     
     
    
 
     
 1 package main
 2 
 3 import (
 4     "fmt"
 5     "runtime/debug"
 6 )
 7 
 8 func test1() {
 9     test2()
10 }
11 
12 func test2() {
13     test3()
14 }
15 
16 func test3() {
17     fmt.Printf("%s", debug.Stack())
18     debug.PrintStack()
19 }
20 
21 func main() {
22     test1()
23 }
