Python debug breakpoint not working on (base)

[brettcannon]

Discussed in microsoft/vscode-python#17152

^{Originally posted by bynkook August 29, 2021}
VS Code Version: 1.59.1 (user setup)
OS Version: Windows 10 19H2

Steps to Reproduce:
Install Miniconda3
Install Vscode, python extension, activate conda (base)
Initial settings with default launch.json, run code in the screenshot with breakpoint. the breakpoint is not working
JustMyCode : false is tested. Not working.
Same test on two different clean machine which never installed python and vscode before.

the debug works fine when a virtual environment create with command such as "conda create -n venv python=3.9.6" Apparently it seems the trouble happens when user is activated (base) without any reason.

Question : Is this a normal situation intended?

Can you provide the logs (for both the case where it works and where it doesn't work)?

i.e.:

• Open VS Code
• Select the command Extensions: Open Extensions Folder
• Locate the Python extension directory, typically of the form ms-python.python-2021.*.****
• In that directory ensure you do not have any debug*.log files, if you do, please delete them
• Go back into VS Code and modify your launch.json to add the setting "logToFile": true, see below:

{
    "name": "Python: Current File (Integrated Terminal)",
    "type": "python",
    "request": "launch",
    "program": "${file}",
    "console": "integratedTerminal",
    "logToFile": true
}

• Start debugging
• When done, go back into the extension directory and upload the debug*.log files into this GitHub issue.

The path to the script being debugged is under C:\Users\...\Miniconda, which is also the base prefix of the Python interpreter if you use base. IIRC that will make your script be treated as if it were a part of the standard library - i.e. it won't be considered "your code" if you have Just My Code enabled (which is true by default). Try setting "justMyCode": false and see if that helps.

(If it is indeed the problem, I would recommend moving your scripts out of that folder. In general, it should only contain the Python implementation, its standard library, and any global packages that you have installed via conda or pip.)

As i mentioned, JustMyCode solution is not working.

I am uploading the *.log files as requested.
debugger.vscode_d624862d-063e-4b8e-b9da-571187ac3ca4.log
debugpy.adapter-14432.log
debugpy.launcher-19900.log
debugpy.pydevd.13940.log
debugpy.server-13940.log

The logs are showing:

"justMyCode": true,

and thus:

sending cmd (http_json) --> CMD_RETURN {"type": "response", "request_seq": 8, "success": true, "command": "setBreakpoints", "body": {"breakpoints": [{"verified": false, "message": "Breakpoint in file excluded by filters.\nNote: may be excluded because of \"justMyCode\" option (default == true).Try setting \"justMyCode\": false in the debug configuration (e.g., launch.json).\n", "source": {"name": "0.py", "path": "c:\\Users\\bk3.lee\\Miniconda3\\userspace\\0.py"}, "line": 1}]}, "seq": 18, "pydevd_cmd_id": 502}

Can you create a launch with "justMyCode": false, and resend the logs where it doesn't work with that launch configuration?

[brettcannon]

@bynkook for the log request.

well i can not believe such simple 2 lined python code is requiring for a unprofessional user to modify internal configuration to set a breakpoint of debugging. anyway i attached the log files as instructed. I want to highlight that JustMyCode:False did not resolve the issue.

Debug configuration keys are case-sensitive; you set "JustMyCode", but the actual key name is "justMyCode".

(Note that you wouldn't have to do this if you didn't keep your user code under C:\Users\...\Miniconda - then it would "just work".)

Indeed all my .py files are under c:\Users[user]\Miniconda3\userspace, the sub folder i created.

Now I can confirm the "justMyCode": false solution is working. Now I think outstanding issue is how to figure out basically why 2 line 'hello world' example is not debugging under conda (base) without adding the magic word.

[bynkook]

Windows 10 19H2
Miniconda3 (3.9.7)
Vscode 1.59.1 portable
Python Extension v2021.9.1191016588

/conda create -n venv
/conda activate venv

After these, a breakpoint assigned, press F5, the terminal says it went back to (base) envionment and breakpoint not working.

This seems to be because of "justMyCode": true instead of "justMyCode": false in the launch configuration.

Do you really think the 2 line Hello World code is requiring custom modification to settings for a simple debugging? Is it intended?

So far, yes, it's intended... You're having problems because you're placing files inside of the directories reserved for conda, which is usually only meant for library directories, whereas most don't have problems because they create project files in directories that are not inside of conda.

I agree that having justMyCode be false by default would actually fix your problem, but there are arguments for having it as true by default (as it is now) too.

Your case could be supported if we implemented: #581 (but it's still not done and given other issues that still hasn't become a priority, so, there's no due date on it).

The simplest solution for your use case it probably moving your project files to a directory that's not considered a library directory (i.e.: move it out of the conda directories).

p.s.: closing issue as things are happening as intended.
