Remote debug Gogland halting

问题

我需要帮助解决在Gogland中使用Delve进行远程调试的问题。

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

首先，启动远程主机上的dlv（从控制台输出）：

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

然后，在IDE中启动远程调试：

从远程主机控制台输出：

2017/07/20 17:23:24 debugger.go:504: continuing
2017/07/20 17:23:24 debugger.go:493: halting

一切都按照我预期的方式工作（断点、F7、F8等）。

然后，我尝试调试我的应用程序：

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:347: created breakpoint: &api.Breakpoint{ID:2, Name:"", Addr:0x6869b2, File:"/home/..........go", Line:66, 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，应用程序会像平常一样启动和运行（RUN）。

我认为这行代码是问题的原因：

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

为什么会出现这个问题？也许我的实用程序结构很复杂（主包分为几个文件，当然还有外部插件包等），或者其他原因？

但是（最有趣的是！），如果您不通过IDE而是通过控制台连接到远程服务器，那么调试在简单示例和我的实用程序的情况下都可以工作：

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

也就是说，我怀疑IDE中存在错误，或者我做错了什么。

我还尝试使用dlv exec（已构建的应用程序）和其他命令进行调试。

感谢您花时间阅读问题，我真的希望能得到帮助。

附注：我也很乐意了解其他用于GO应用程序的远程调试工具。

附注：我尝试在Atom.io和VS Code中进行远程调试
在Atom中，仅本地调试与dlv一起工作。

在VS Code中，本地调试通过dlv +远程调试器工作，但断点不起作用！也就是说，VS Code也不是一个选择。
配置VS Code（launch.json）

I need help with Remote debugging in Gogland with Delve.

I try to debug my app on remote server with IDE Goglang (1.0 EAP) and dlv link: https://github.com/derekparker/delve/

Install and try remote debug simple program:

package main

import &quot;fmt&quot;

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

Firstly, start dlv on remote host (output from console):

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

Then, start remote debug in IDE:

Out from remote host console:

IDE debug does not work (hangs up). If I don't use breakpoints app start and run like a usual (RUN).

I think this line is the reason for my problem:

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

Why does it arise ?? Maybe I have a complicated utility structure (the main package is divided into several files, of course there are external plug-in packages, etc.) or something else?

BUT (! the most interesting !) is that if you join a remote server not through the IDE, but through the console, then debugging works on a simple example and in the case of my utility:

dlv connect HOSTNAME:2345
Type &#39;help&#39; for list of commands.
(dlv) b ********.go:137
Breakpoint 1 set at 0x687a86 for main.main() /home/*************.go:137
(dlv) c
&gt; main.main() /home/***************************.go:137 (hits goroutine(1):1 total:1) (PC: 0x687a86)
(dlv) n

Output:

$ 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: &amp;api.Breakpoint{ID:1, Name:&quot;&quot;, Addr:0x687a86, File:&quot;/home/*******************.go&quot;, Line:137, FunctionName:&quot;main.main&quot;, Cond:&quot;&quot;, 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

Those. There is a suspicion of an error in the IDE, or I'm doing something wrong :).

I also try debug with dlv exec (already build app) and other command.

Thanks for the time given to the question, I really hope for help.

P.S. I will also be glad to know what else you can use for remote debugging for GO app.

P.P.S. I tried to make remote debugging in Atom.io and in VS code
In Atom, work only locale debug with dlv.

In VS code the local debugger works through dlv + remote debugger works, but breakpoints doesn't work !!! Those. VS Code is also not an option.
