vscode-python 0.8.0 makes all debugging services of vscode 1.18 non-working about vscode-python

[b-hahn]

I have the same issue:

VS Code version 1.18
Python version: 2.7.14
OS: Ubuntu 14.04

[DonJayamanne]

vscode related to debugging (Start Debugging, Open Configurations etc.) stops working.

Please could you describe what you means by stops working.

1. Please could you provide the exact steps, such as:

• Opened a workspace with a python and javascript file
• Debugging javascript file works
• When debugging python file, the following errors are displayed ... (provide details of errors in logs)

2. Please provide the following:

• Contents of the launch.json file
• Sample python file being used

3. Please confirm there are no errors in the Console window, accessed from Help->Developer Tools menu)
   It sounds highly unlikely there are no errors in there. If debugging other languages does not work, then errors must be logged somewhere, also the Python extension should not affect other debuggers.

4. Finally, please try uninstalling and re-installing the extension.

Ok, I'll be more specific.

I created a new directory and run code . inside. It only contains .vscode/launch.json with

{
    // 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": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${file}"
        }
    ]
}

Now I have 2 cases:

• Case 1 (vscode-python extension is disabled):

Choosing in vscode menu Debug->Open Configurations opens launch.json for editing - expected behavior

• Case 2 (vscode-python extension is enabled):

The same action silently fails: launch.json is not opened, developers' console contains the following errors (sorry, I initially overlooked them):

Reinstalling the extension does not help.

I think this can be related to #57

[DonJayamanne]

Great, looks like there's an error and that's the problem. This isn't related to #57.
Thanks for the output from the console window.

[DonJayamanne]

@b-hahn
You must be experiencing some other issue. Please could you provide the contents of your Python output panel and the console widow (Help->Developer Tools menu)
There must be something in both, specially console window.

[b-hahn]

@DonJayamanne Indeed it seems like my problem is different. I tried again and now I get the following: when I debug some python code it takes longer until it breaks at the beginning of the code. I then get the following error message in the console:

It then proceeds to debug as it used to before the update (don't know if I had the same error then as well).

If I run the python file without debugging then it runs once but I can't run it a second time, either with or without debugging. The little blue status bar on the top left keeps on moving, as if the process hadn't terminated, although the code seems to get to the last line and it worked before the update. This happens with one-line print statement as well so I don't think it's my code. I have to restart VS Code to run it again. Here I don't get any errors either in the console or the python output window.

I'm using this launch.json:

...
{
            "name": "Python",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "pythonPath": "${config:python.pythonPath}",
            "program": "${file}",
            "cwd": "${workspaceRoot}",
            "env": {},
            "envFile": "${workspaceRoot}/.env",
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        },
...

Let me know if you need anything else!

[DonJayamanne]

@b-hahn please could you create a separate issue for the problem you are experiencing (with all relevant information). Gets quite difficult to manage multiple problems from the same issue. Thanks.
One last thing, please try to add a screen shot of the error message.

[b-hahn]

@DonJayamanne Sure, I just created a separate issue. Regarding the screen shot, I don't get an error message so I can't really attach anything, I simply can't run code after I've used the "Start without Debugging" function once. Let me know if you need anything else!

[rob3c]

I wish I were lucky enough to get an error message. It just hangs indefinitely for me in Code, and - surprisingly - trying to debug a python app in Code-Insiders starts an instance of Code instead of debugging my app! This is all with a configuration that's been working solidly for me for weeks now.
