Breakpoints stoppped working

[booleangate]

Issue Type: Bug

As of 1.28.1, breakpoints in debugger suspend application, but debugger UI is not activated (cannot step debug).

1. Run application through debugger.
2. Execute code path that contains a breakpoint. Application is suspended, but debugger UI does not update to allow you to actually step debug.

Can yuo reproduce this with latest vscode insiders https://code.visualstudio.com/insiders/
If yes, can you please write some reproducable steps so we actually try to debug this. What application are you debugging, can you share it and so on. Minimal reproducable steps please.

[booleangate]

I can reproduce this with VS Code Insiders. In my Go application, I set a break point and start the debugger using the following launch.json:

{
    // 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": "API",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "/Users/johnsonj/dev/omnivore/giganto/om/backend/api/cmd/api/main.go",
            "env": {},
            "args": [
                "/Users/johnsonj/dev/omnivore/giganto/om/backend/api/config/config.ini",
                "/Users/johnsonj/dev/omnivore/giganto/om/backend/api/config/dev_config.ini"
            ],
            "showLog": true
        }
    ]
}

When execution hits a break point, the application is suspended but the UI is not right.

You can see that the break point line is highlighted, but the step tools are in the wrong mode (as if no break point has been encountered and execution is not suspended.

Unfortunately, I cannot share the application. Is there any environment information or logging that I can give you?

[isidorn]

@booleangate thanks for providing more details.
I would actually start with going to the go extension https://github.com/Microsoft/vscode-go so that they investigate on their side first. Can you please also create an issue there

I will keep this issue open so I am aware of it.
What happens if you expand one of those threads you have in the screen shot under the CALL STACK view. If you click on a stack frame does the debug toolbar show the proper actions?

[booleangate]

Interesting, the stack is empty for the paused thread:

Should I still open an issue with vscode-go or does this point you in a new direction?

[jinmatt]

👍
Having the same issue in VS code(not insiders)

[isidorn]

@booleangate yes please open an issue with vscode-go and they can start investigating. Thanks

[isidorn]

@ramya-rao-a are you also owning the go debug adapter? If yes did something change there and did you have users filling similar issues?
Thanks

[ramya-rao-a]

@isidorn Yes, I own the Go debug adapter as well. @roblourens helps me there from time to time.
Nothing changed there in the recent past.

[ramya-rao-a]

@booleangate Please add "trace": "verbose" to your debug configuration, try again and share the logs that get printed to the debug console.

Also, do you see similar issue in a simpler program that you can share?

[jinmatt]

Switched back to August release 1.27.2, and works as it used to.

@ramya-rao-a here is the trace from 1.28.1:

[jinmatt]

The issue for me is only when I'm trying to hit an http handler endpoint. Works well if I put a breakpoint in a main.go file(or any startup location).

[booleangate]

@ramya-rao-a Here's the debug log. Downgrading to 1.27.2 also fixes my problem.

@jinmatt pointed out that he experiences the same thing in http endpoint handlers but not in main. I did a test and confirmed that I am experiencing the same problem with my application. Break points in main trigger as expected, but break points in http handlers exhibit the reported behavior.

@jinmatt Are you able to share your application?

[isidorn]

@jinmatt yeah a reproducable case would be really useful here for us to investigate more.
@booleangate or you could try to crate a minimal reproducable sample for you which you could share

fyi @weinand

[booleangate]

I'm sick and barely functioning 😷 I'll try to whip something up when I'm on my feet again.

[isidorn]

Also try F1 > developer tools and opend debug console for potential errors
