Describe the bug

When run any test with break point, I want to inspect variables, the debug view under activity bar ,show variables right:

But when I changed to vscode's debug console view, and inspect same var using dlv's command, there are strange rand key shown up:

If inspect with map, there are so many rand runes, witch seems annoying and confused with real inspect variable:

@zzjin Thanks for the report!

Could you collect the logs by adding "showLog": true, "logOutput": "dap,debugger" to your launch configuration and sharing the Debug Console contents?

If you could also share a repro case that would be great!

[zzjin]

Sorry for the delayed response.

I've tested add log conf to lanuch.json and start debugging, but found Output-GO Debug view without even one words:

If you could also share a repro case that would be great!

The test case is so simple and would trigger every-time, when start inspect one map using dlv:

package main

import (
	"testing"

	v1 "k8s.io/apiextensions-apiserver/pkg/apis/apiextensions/v1"
)

func TestImportedPackage(t *testing.T) {
	data := map[string]v1.JSONSchemaProps{
		"a": {Description: "A info", Type: "string"},
		"b": {Description: "B info", Type: "string"},
		"c": {Description: "C info", Type: "string"},
	}
	if len(data) == 3 {
		t.Error("no")
	}
}

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch test function",
            "type": "go",
            "request": "launch",
            "mode": "test",
            "program": "${workspaceFolder}",
            "args": [
                "-test.run",
                "TestImportedPackage"
            ]
        }
    ],
    "showLog": true,
    "logOutput": "dap,debugger",
}

Strange view:

In addition, I found that debug map using some other packages, debug output view is displayed right:

package main

import (
	"testing"

	"golang.org/x/net/html"
)

func TestHTML(t *testing.T) {
	data := map[string]html.Attribute{
		"a": {Namespace: "A info", Key: "string"},
		"b": {Namespace: "B info", Key: "string"},
		"c": {Namespace: "C info", Key: "string"},
	}

	if len(data) == 3 {
		t.Error("no")
	}
}

Thanks for all of the information. I was able to recreate the issue when I upgraded to the latest VS Code release.

Filed an issue upstream microsoft/vscode#176798
