Debug file not getting cleared after debugging on Windows

[monkeyWie]

1. Start debug
2. Generate debug file

Is this normal?Can I hide it？

[cousinbenson]

this is normal, you cannot hide it however you can .gitignore it

[segevfiner]

I think that's how delve works.

[ramya-rao-a]

We use delve to provide the debugging feature.
It builds your code, creates a binary (the debug file you are seeing) and uses that to do the debugging.
This file should get deleted at the end of the debug session.
If you are seeing that it is not getting cleaned up, then please provide a small sample code and exact repro steps.

I just run a hello word program,then this is my code:

.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${fileDirname}",
            "env": {},
            "args": []
        }
    ]
}

src/main.go

package main

import (
	"fmt"
)

func main() {
	fmt.Println("Hello word")
}

The version info

VSCode version:1.30.2
Go plugin version:0.8.0
Delve version:1.1.0

Steps

1. Press F5 to debug
2. Found the DEBUG file after the program finishes running.

[ramya-rao-a]

When you have finished debugging, the file doesn't get cleaned up?
What OS are you using?

[monkeyWie]

Yes, the debug file has not been cleared.
OS: win10 Pro 1803

Thanks @monkeyWie

I see this in Windows, but not on my Mac.

[ramya-rao-a]

@jhendrixMSFT This is most likely due to delve.

By the time we send the Halt request to delve, delve has already completed running the whole program. So the Halt request fails with Process <process-number> has exited with status 0

I would expect delve to clean up the debug file it created in such cases, we should look into why this is not happening as well as why it does happen on Mac

[ramya-rao-a]

@vladbarosan Right now we end up at https://github.com/Microsoft/vscode-go/blob/0.9.0/src/debugAdapter/goDebug.ts#L533 failing to halt delve because delve has already halted (sort of)

I am not sure if the Halt request failed here or the Detach request.
If it is the Halt request that is failing, then maybe we should try running Detach request nevertheless? Not sure.

@monkeyWie The fix for this is available in the latest beta version of this extension. Please give it a try

[monkeyWie]

Thank you, I will try it when I have time.

[monkeyWie]

Bug has been fixed.

@ramya-rao-a
I found a new bug in 0.9.3-beta.7.
When I set a breakpoint for debugging,debug file is not getting cleared after the program ends.

[ramya-rao-a]

@monkeyWie Can you create a new issue for that?

The fix that was put in place for this issue is out in the latest release(0.10.0) of this extension
