Indefinitely "Discovering Python Interpreters" due to faulty conda binary

Type: Bug

Behaviour

Expected vs. Actual

When i open a python project the language server never loads. It just stalls on "discovering python interpreters" forever.

In the output section i've put just one example of the errors ms-python is outputting. All the other errors are copies of the ones there but with different environment names and python versions.
It looks like it's searching for my old, deleted virtualenvs. I don't know where it's saving its information about those old envs or i'd delete that.

Steps to reproduce:

Open a python project with vscode-remote on my machine?

I'm sure it's something weird about my setup but i can't pin it down. I've reinstalled vscode, vscode-server, all extensions, ect.

Try out the pre-release version of the extension:

You may need to clear cache using Python: Clear cache and reload command.

Switching to pre-release didn't do anything. Clearing cache got rid of all the environment failures. Now I'm left with this set of warnings/errors that were probably the true cause all along. It's progress, any other ideas?

When i open a python project the language server never loads

The intention of pre-release was to help with this. We just made a fix to ensure Interpreter discovery to not block LS: #22041, so even if Discovery does not finish, LS should ideally start, as long as you see an active interpreter on the bottom right:

Can you confirm whether you see it? Your log seems to indicate: Python interpreter path: ~/.pyenv/versions/3.10.5/bin/python, which suggests you do.

it waits for about a full minute (where i don't see an active interpreter) then selects an interpreter.

However, code completion is broken even after an active interpreter is selected.

Oh and I made a mistake when i said clearing the cache fixed the environment errors. They just took longer to show up after clearing the cache. It's still throwing errors while looking for the same deleted environments.

I'll also remind you that i'm using vscode remote ssh'd into an ubuntu box. Since that has often been a factor in previous issues i've had.

Oh i seem to have fixed code completion for now. I opened vscode without being ssh'd into the linux box and cleared the cache. That seems to have worked. I almost never open vscode without using vscode-remote so i hadn't tried that.

Now it's just stuck on "Refreshing Python Interpreters" but at least I can ignore that and still work effectively.

Great, now we can work on making that go away. For that I would need the complete debug logs:

Run Developer: Set log level command
Select Python -> Select Trace
Run Developer: Reload Window command
Provide the output:

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

It's still throwing errors while looking for the same deleted environments.

It's likely that other extensions like Jupyter are still looking for those deleted environments, in which you can try disabling the extension. The logs should contain this info as well.

Explicitly continue execution after timeout on launching conda binary…
