golang debug调试

1. debug by gdb:

download the runtime-gdb file.

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

$ sed -i -e "s/<span.*span>//g" -e "s/<pre>//g" -e "s/^\t//g" -e 's/"/"/g' -e "s/'/'/g" -e "s/>/>/g" -e "s/</</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

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 }
