debugging - 远程调试 Gogland 停止

Question

我需要有关使用 Delve 在 Gogland 中进行远程调试的帮助。

我尝试使用 IDE Goglang (1.0 EAP) 和 dlv 链接在远程服务器上调试我的应用程序:https://github.com/derekparker/delve/

安装并尝试远程调试简单程序:

package main

import "fmt"

func main() {
    fmt.Println("hello world")
    for i:=uint(0); i< 10; i++{
        fmt.Println(i)
    }
}

首先，在远程主机上启动 dlv(控制台输出):

$ dlv debug --headless --listen=:2345 --log --api-version=2
API server listening at: [::]:2345

然后，在IDE中开始远程调试:

从远程主机控制台输出:

2017/07/20 17:23:24 debugger.go:493: halting

一切如我所料(断点、F7、F8 等)

然后我尝试调试我的APP:

dlv debug --headless --listen=:2345 --log --api-version=2 -- --v --console
2017/07/20 17:26:51 debugger.go:97: launching process with args: [/home/...../debug --v --console]
API server listening at: [::]:2345

IDE 启动

输出:

2017/07/20 17:26:55 debugger.go:493: halting
2017/07/20 17:26:55 debugger.go:347: created breakpoint: &api.Breakpoint{ID:1, Name:"", Addr:0x687a73, File:"/home/..........go", Line:136, FunctionName:"main.main", Cond:"", Tracepoint:false, Goroutine:false, Stacktrace:0, Variables:[]string(nil), LoadArgs:(*api.LoadConfig)(nil), LoadLocals:(*api.LoadConfig)(nil), HitCount:map[string]uint64{}, TotalHitCount:0x0}

2017/07/20 17:26:55 debugger.go:504: continuing
2017/07/20 17:26:55 debugger.go:347: created breakpoint: &api.Breakpoint{ID:3, Name:"", Addr:0x687d33, File:"/home/........go", Line:143, FunctionName:"main.main", Cond:"", Tracepoint:false, Goroutine:false, Stacktrace:0, Variables:[]string(nil), LoadArgs:(*api.LoadConfig)(nil), LoadLocals:(*api.LoadConfig)(nil), HitCount:map[string]uint64{}, TotalHitCount:0x0}
2017/07/20 17:26:55 debugger.go:504: continuing
2017/07/20 17:26:57 debugger.go:516: nexting

IDE 调试不起作用(挂起)。如果我不使用断点应用程序启动并像往常一样运行 (RUN)。

我认为这条线是我的问题的原因:

2017/07/20 17:26:45 debugger.go:493:暂停

为什么会出现？？可能是我的实用结构比较复杂(主包分为几个文件，当然还有外挂包等等)还是别的？

但是(!最有趣的!)是，如果您不是通过 IDE，而是通过控制台加入远程服务器，那么调试就可以在一个简单的示例上进行，对于我的实用程序:

dlv connect HOSTNAME:2345
Type 'help' for list of commands.
(dlv) b ********.go:137
Breakpoint 1 set at 0x687a86 for main.main() /home/*************.go:137
(dlv) c
> main.main() /home/***************************.go:137 (hits goroutine(1):1 total:1) (PC: 0x687a86)
(dlv) n

输出:

$ dlv debug --headless --listen=:2345 --log --api-version=2 -- --v --console
2017/07/20 17:37:37 debugger.go:97: launching process with args: [/home/*****************/debug --v --console]
API server listening at: [::]:2345
2017/07/20 17:38:27 debugger.go:347: created breakpoint: &api.Breakpoint{ID:1, Name:"", Addr:0x687a86, File:"/home/*******************.go", Line:137, FunctionName:"main.main", Cond:"", Tracepoint:false, Goroutine:false, Stacktrace:0, Variables:[]string(nil), LoadArgs:(*api.LoadConfig)(nil), LoadLocals:(*api.LoadConfig)(nil), HitCount:map[string]uint64{}, TotalHitCount:0x0}
2017/07/20 17:38:35 debugger.go:504: continuing
2017/07/20 17:38:39 debugger.go:516: nexting

那些。怀疑IDE有错误，或者我做错了什么:)。

我还尝试使用 dlv exec(已经构建应用程序)和其他命令进行调试。

感谢您花时间回答这个问题，我真的希望得到帮助。

附言我也很高兴知道您还可以使用什么来远程调试 GO 应用程序。

附言我尝试在 Atom.io 和 VS 代码中进行远程调试在 Atom 中，仅使用 dlv 进行语言环境调试。

在 VS 代码中，本地调试器通过 dlv + 远程调试器工作，但断点不起作用!那些。 VS Code 也不是一个选项。配置 VS 代码 (launch.json)

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "REMOTE",
            "type": "go",
            "request": "launch",
            "mode": "remote",
            "remotePath": "{workspaceRoot}",
            "port": 2345,
            "host": "REMOTE_HOST_NAME",
            "program":  "${workspaceRoot}", //"${fileDirname}",
            "env": {},
            "args": ["--v", "--console"],
            "showLog": true
        }
    ]
}
