Error `Bad file descriptor` during using prompt-toolkit with xonsh #1853

Open anki-code opened 4 months ago

anki-code commented 4 months ago

Hey! I see many stable repeatable cases when prompt-toolkit shows the Bad file descriptor error. It makes xonsh shell users sad.

You can find the latest most repeatable report in this comment.

Please help to fix this.

Thanks!

@jonathanslenders sorry for direct mention but it's very annoying issue and help will be very appreciated.

I found that issue appeared starting from prompt-toolkit 3.0.41 where asyncio was introduced (https://github.com/prompt-toolkit/python-prompt-toolkit/commit/8c601936b11d91388edc653df80aa34bd9cb1606).

After this commit xonsh users continuously facing with this:
