Mode periodically loses characters as I type #158

Closed cubranic closed 5 years ago

cubranic commented 5 years ago

I'm using swift-mode with Spacemacs on Emacs 26.1 (just a straight package-install, not as a layer). As I type, there is something that the mode does that causes it to swallow characters. I can tell that some kind of background operation is in progress when that happens because whenever a character is dropped I also see "Quit" appear in the minibuffer.

I tried to dig a little deeper by setting the "Enter debugger on Quit" and "Enter debugger on error", but it was never entered. I understand that this may be hard to reproduce on another machine, so if you give me any instructions on how to debug this further, I'd be happy to try it.

I have started Spacemacs 26.1 with Docker in Linux, and used it for a few minutes, but it was not reproduced.

If you use Linux, try a quick test.

  1. Open a Spacemacs
  2. Visit a new file
  3. Run the script

Try it a few times with different filenames, then compare the results with diff.

(I should have clarified that I'm on a Mac.)

I started my Spacemacs with no .spacemacs and started with a clean config. I don't see the bug any more, so I'm next going to identify the differences with my own .spacemacs and report back here.

It looks like an existing package in my .emacs.d/elpa/ was causing this. When I started with the same config and clean package directory, the bug doesn't show. (I suspect company, but it's not worth checking at this point.)
