Python-language-server: Cache directory being created in working dir

[doron-cohen]

After running vscode for a couple of minutes a cache directory is being created in current working directory:

>>> find XDG_CACHE_HOME -type d
XDG_CACHE_HOME
XDG_CACHE_HOME/Microsoft
XDG_CACHE_HOME/Microsoft/Python Language Server

This started a few days ago. my guess is that someone forgot to add $ to the environment variable.

I'm getting this too. I'm on Ubuntu, here's the VS Code About:

Bug here: https://github.com/microsoft/python-language-server/blob/91e912c2761e940c171f490cb64bbb08b5c9999d/src/Analysis/Ast/Impl/Caching/CacheFolders.cs#L75

xdgCacheHomePath needs to be the path, not xdgCacheVarName.

I'm getting this bug as well, though only when using the snap version.

The fix was just merged and built into daily. If you want it now, you can switch up, but I expect that we'll push out to the stable channel soon.
