golang debug調試

1. debug by gdb:

office doc

 download the runtime-gdb file.

$ wget -q -O - https://golang.org/src/runtime/runtime-gdb.py  |grep '<span id="L' >  runtime-gdb.py

處理脫字符

$ sed -i -e "s/<span.*span>//g" -e "s/<pre>//g" -e "s/^\t//g" -e 's/&#34;/"/g' -e "s/&#39;/'/g" -e "s/&gt;/>/g" -e "s/&lt;/</g" -e "s/amp;//g" runtime-gdb.py 

linux 下應該有脫字符處理工具(iconv)。　或者wget 自己應該能處理掉脫字符。

 

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

中文參考

 發現最新的golang1.6已經自帶了runtime-gdb.py

進入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".

直接運行

$ gdb your_bin 

２．　godebug

http://studygolang.com/articles/2899

Download:

$ go get -u github.com/mailgun/godebug

將　_ = "breakpoint"　插入代碼。

 1 package main
 2 
 3 import (
 4     "fmt"
 5 )
 6 
 7 func main() {
 8     _ = "breakpoint"
 9     fmt.Print("**********************\n")
10 }

build godbug

$ go build 

mv  godbug to goroot bin

$ sudo cp godebug /usr/local/go/bin/

$ debug

godbug run your go_file.

3.  Go語言debug調試

4. 採用idea IDE環境。

5. 使用Delve進行Golang代碼的調試

http://www.qingpingshan.com/jb/go/111271.html

$ dlv  exec  ./sample-controller -- -kubeconfig=$HOME/.kube/config

使用Delve調試test case

dlv test --build-flags='github.com/dlsniper/u/tmp/mypack' -- -test.run ^TestHello$

6. 代碼中打印棧信息

 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 }
