在2019-02-26 在ubuntu上除錯go-ethereum 中，goland無法在ubuntu下除錯，但是dlv除錯又太複雜，因此參考以太坊 (go-ethereum) 編譯除錯環境的搭建 ，搞定了vscode在ubuntu上的除錯
1、安裝go外掛
需要安裝：
go get -u -v github.com/nsf/gocode go get -u -v github.com/rogpeppe/godef go get -u -v github.com/golang/lint/golint go get -u -v github.com/lukehoban/go-outline go get -u -v sourcegraph.com/sqs/goreturns go get -u -v golang.org/x/tools/cmd/gorename go get -u -v github.com/tpng/gopkgs go get -u -v github.com/newhook/go-symbols go get -u -v golang.org/x/tools/cmd/guru go get -v -u github.com/peterh/liner github.com/derekparker/delve/cmd/dlv
2、配置vscode
檔案launch.json內容如下：
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/build/bin/geth",
"args": ["--datadir",
"/home/elikong/go/src/github.com/ethereum/go-ethereum/build/bin/geth-data0",
"--networkid",
"1314",
"--nodiscover",
"--rpcport",
"6001",
"--port",
"30001",
"--ipcpath",
"geth1.ipc",
"console"],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
}
]
}
主要是在自動生成的檔案上修改了program和args引數
3、除錯
使用ctrl+p開啟檔案ethapi\api.go，找到函式func (s *PublicTransactionPoolAPI) SendTransaction
在函式第一行設定斷點
參考2018-11-22 Debug以太坊go-ethereum實戰 除錯轉賬
./geth attach ./geth-data0/geth1.ipc
miner.start()
personal.unlockAccount(eth.accounts[0])
eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[1],value:web3.toWei(10,"ether")})
