2019-03-08 在ubuntu上调试go-ethereum(2)

在2019-02-26 在ubuntu上调试go-ethereum中，goland无法在ubuntu下调试，但是dlv调试又太复杂，因此参考以太坊 (go-ethereum) 编译调试环境的搭建，搞定了vscode在ubuntu上的调试

1、安装go插件

参考golang VScode安装与配置

需要安装：

代码语言：javascript复制

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

文件launch.json内容如下：

代码语言：javascript复制

{
    // 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
                }
            ]
        }
    ]
}

主要是在自动生成的文件上修改了program和args参数

3、调试

使用ctrl p打开文件ethapiapi.go，找到函数func (s *PublicTransactionPoolAPI) SendTransaction

在函数第一行设置断点

参考2018-11-22 Debug以太坊go-ethereum实战调试转账

代码语言：javascript复制

./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")})
