Affected language servers

jedi-language-server

How to reproduce the issue

1. Open a Python file or project.
2. Wait for lsp works.
3. Exit.
4. Repeat several times.
5. Open process panel tools like top and the problem shows.
   

Actual behavior

The CPU usage of Jedi language server is extremely high, and it does not automatically exit when exiting neovim. If I repeatedly open and close Python files, multiple instances of Jedi language server will appear, causing significant CPU usage. As this issue affects user experience and computer performance, it is suggested to fix it.

Does it have to do with the uninstalled pyright?

Does it have to do with the uninstalled pyright?

I just noticed that the project replaced pyright with jedi-language-server, but after uninstalling pyright by mason, the situation remains the same.

Never encountered this, you can remove jedi for yourself and try others like pylsp. Need more issues about it to decide.

[Tgist1024]

Well... I found that using :wq to save and exit leads to the issue I mentioned while using :q does not.
I think the issue might be caused by code formatting. You can try again and see if it occurs.

OK, I captured this and it should be normal because pylsp also have this issue.
It's reasonable that lsp need some time to stop.


But indeed jedi has abnormal high CPU load about a few seconds.

Will fix it with pylsp.
