• VS Code version: 1.32.3
• Extension version (available under the Extensions sidebar): 2019.2.5558
• OS and version: Windows_NT x64 10.0.17763
• Python version (& distribution if applicable, e.g. Anaconda): 3.6.2 (from Python.org directly)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Relevant/affected Python packages and their versions: None

Expected behaviour

When VSCode is used to debug a Python 3.6 script I anticipate for the execution of the code to stop when a breakpoint is 'hit'.

Actual behaviour

The code simply continues running as if the breakpoint wasn't there at all

Steps to reproduce:

1. Create an empty directory
2. Open VSCode and start a terminal session within that directory
3. python -m venv .
4. Click the "Trash Can" icon associated with the currently open terminal
5. CTRL+SHIFT+P > Python : Select Interpreter
6. Select any available interpreter to initiate the .vscode/settings.json file
7. Open the .vscode/settings.json file and change the "python.pythonPath": variable from the previously selected interpretter to be .\\Scripts\\python.exe
8. Set .vscode/launch.json to have the following contents :

{
    "version": "0.2.0",
    "configurations": [{
        "name": "Python: Current File (Integrated Terminal)",
        "type": "python",
        "request": "launch",
        "program": "${file}",
        "console": "integratedTerminal"
    }, ]
}

9. CTRL-` (open new terminal) , this should use the venv environment at this point by default, this is just to confirm that it is indeed being used.
10. Create a simple python script , like this :

from time import sleep
count = 0
while True:
    print(f'Count = {count}')
    sleep(1)
    count += 1

11. Add a breakpoint at any point, for testing I used line 7 ( count += 1 )
12. Click the "Debug" icon on the left hand menu bar
13. Click the green "play" button at the top of the panel that appears
14. Watch the counter go up without ever stopping

Instead of creating a venv in the root directory of your project please create a sub-directory for your venv (i.e. a sub directory within your project folder).
FYI - Generally its considered a bad practice to place your source files inside of a venv.

---

@primalewden commented on Wed Mar 20 2019

Hello,

As per your advisement however I have relocated the source files to a separate directory from the venv directory.

I now have the following structure :
/some_dir/venv_folder
/some_dir/source_folder

I open the source_folder with VSCode and first select one of the existing Python installations I have then edit the .vscode/settings.json file as per the description above, except now I am using an absolute path leading to the Python.exe instance within the venv_folder/scripts.

When I run debug it enters that venv , verified by the (venv_folder) that precedes the path the terminal is currently in.

Even with the abstraction away from the venv folder I am experiencing the same result. Did I misunderstand your suggestion?

Thank you for your time, I really appreciate it!

@marvingreenberg commented on Wed Apr 03 2019

I'm having the same issue with a different environment - not a remote debug, no venv, python 2.7. Making a simple test_foo.py module with a unittest class works, but my test_deploycfg,py module in the same folder of the same workspace, with a few unittest.TestCase classes each with a few dozen test_ methods does not. Setting breakpoints and running a single test case with "Debug Test" code lens behaves the same as "Run Test".

---

@marvingreenberg commented on Wed Apr 03 2019

Here is my Developer Tools output. The first 4 entries are the failing test_deploycfg.py, where breakpoints are ignored. The next 3 entries are from debugging a single test in test_foo.py, where breakpoints are hit and stepping works fine.

And, the problem seems to be something about "Debug Test" code lens, perhaps. If I set breakpoints in a bunch of the individual tests, clicking "Debug Test" in one test method (test_generated) it is stopping at a breakpoint in a different test (test_refs)

I am having the same issue.

Program will not stop at breakpoint line 5.

Here is launch.json.

Here is my debug file:

I've been trying to figure this out for a little while now, in my own circumstance, and am able to hit breakpoints, but only when a given python file is in my user directory and the interpreter is /usr/bin/python. I haven't been able to debug things with /usr/lib/ckan/default/bin/python. It seems to come down to filesystem location and maybe which python interpreter.

1. Have tried debugging files located inside my user directory using the interpreter in /usr/lib/ckan/default/bin/python (virtualenv)
2. Have tried copying files from /usr/lib/ckan/default to my home directory and debugging them with the above interpreter
3. I've tried a lot of things that pretty much all resulted in an indication that it was the location of the drive

[karthiknadig]

@LukeTully try `"justMyCode": false" in your launch config. That should allow you to debug everything. If files are getting ignored that is probably because we try to figure out which ones are user files and which ones aren't. that detection can miss things if the path is in any of the common interpreter or standard library locations. justMyCode set to false will turn off that filtering.

[LukeTully]

@karthiknadig I have enough experience to know that something this trivial would be the solution, but thank you, it solved the problem. At least this validates the debugging outcomes I was seeing!

Although I would add that I did have "Allow breakpoints everywhere" checked on in all 3 settings files through the settings UI.

@karthiknadig @int19h

(previous thread on this:
#1325 (comment))

So, it seems that the current implementation is still not ideal because we're still hitting this issue... I'll take another look at this using sysconfig as pointed by: #1325 (comment)

[fabioz]

Another thing that just occurred to me is that we should probably say that a breakpoint is not validated if the related file will not be traced and let the user know why. I'll use this issue to add this handling too.

[karthiknadig]

@fabioz This might be relevant as well, for breakpoint validation. #1298

[fabioz]

Note that I just provided a fix for discovering the paths to be considered standard libraries, I'll use #1298 for the breakpoints validation.
