Issue with Emacs 26

[noxdafox]

Greetings,

I was trying out Emacs 26 from Debian shanpshots and I get a very lengthy error as soon as I activate ycmd-mode.

This repeats on every request against the YCMD server. The server logs do not show any error.

ycmd and emacs-ycmd are both up-to-date.

Reverting to Emacs 25 "fixes" the issue.

[abingham]

Hmmm. It definitely works with Emacs 26 for me, but let me poke at it a bit and see what the problem might be. What versions of request and request-deferred are you using?

[noxdafox]

request: 20170131.1747 request-deferred: 20160419.1605

[abingham]

Those are the versions I'm using, and everything seems to work for me on 26. I'm grasping at straws here, but could you clean out all of your .elc files before running 26?

[abingham]

FWIW, I just went through a 25->26 transition on one of my machines. I was initially seeing the same problem as you, but after clearing out my elpa directory everything (well, ycmd at least) seems to work.

[noxdafox]

I suspect it's something similar, I will try tonight and let you know.

[noxdafox]

Indeed it was the case. Removing all .elc files fixed the issue.

Do you know if there's a way I can do it via elpa or Emacs? Some command to clear the binary of the packages?

[abingham]

Hmmm, not sure about that. There's byte-recompile-directory, but I'm not sure if that will know that an elc is out of date due to a version upgrade.
