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 '<span id="L' >  runtime-gdb.py

处理脱字符

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

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。

 package main

 import (
     "fmt"
 )

 func main() {
     _ = "breakpoint"
     fmt.Print("**********************\n")
 }

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$

6. 代码中打印栈信息

 package main

 import (
     "fmt"
     "runtime/debug"
 )

 func test1() {
     test2()
 }

 func test2() {
     test3()
 }

 func test3() {
     fmt.Printf("%s", debug.Stack())
     debug.PrintStack()
 }

 func main() {
     test1()
 }
