justMyCode stopped working after version 2024.10.0

[musateduard]

hi,

i'm using vs code with the python debugger extension and i noticed that recently stepping into 3rd party libraries stopped working. the version that i noticed this happening on is 2024.14.0 and the last version where i could get it to work is 2024.10.0 which is the one that i currently switched to. can someone have a look into this?

thanks

python version: 3.12.0
os version: windows 10 10.0.19045
vs code version: 1.96.0
current debugger version: 2024.14.0
last working version: 2024.10.0

launch.json config

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": false
        },
        {
            "name": "Python: Tests",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "purpose": ["debug-test"],
            "console": "integratedTerminal",
            "justMyCode": false
        }
    ]
}

I also got the same issue.

• OS: maxOS Sonoma 14.6.1
• Python: 3.12.3
• Python Debugger: 2024.14.0

And I faced the same message "Frame skipped from debugging during step-in." like as @Real-Gecko commented: microsoft/vscode-python-debugger#139 (comment)

This only seems to reproduce with test debugging. Not sure why at the moment.

If you use this for debugging a file, stepping into 3rd party libraries works fine:

        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "purpose": ["debug-in-terminal"],
            "console": "integratedTerminal",
            "justMyCode": false,
            "logToFile": true
        },

But this won't (when debugging tests)

        {
            "name": "Python: Debug Tests",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "purpose": [
                "debug-test"
            ],
            "console": "integratedTerminal",
            "justMyCode": false,
            "logToFile": true
        }

The only difference I see in the launch is the 'rules' section of the launch args.

        "rules": [
            {
                "include": false,
                "path": "c:\\Users\\rchiodo\\.vscode-insiders\\extensions\\ms-python.python-2024.23.2024121701-win32-x64\\python_files"
            }
        ],

The normal debug launch doesn't include those rules, the test debug launch does. I don't think that should be interfering though, but maybe there's a bug in the include matching.

Here's the example test I used:

import pytest

def test_debugstepinto():
    pytest.approx(1.0, 1.2) # Try stepping into this line. 
    print("after")

It also works for 3.11 or earlier. Must be a bug in the sys.monitoring code

Found the location. We're not using the 'justMyCode' setting in the sys.monitoring to code to check if we should filter things not in the project scope.
