emacs 30, macos, zmq error

[danielpopescu]

Hello,

Just started getting this error (org version 9.7.5, latest of everything, macos, native compilation):

Any ideas?

It should be due to the the new commit of Emacs 30. Similar issue here: https://github.com/emacs-jupyter/jupyter/issues/540

[danielpopescu]

Thank you!

If I turn zmq off with (setq jupyter-use-zmq nil)

then I get this (on macos, on linux it works fine):

Launching notebook process on port 8888...done progn: Jupyter REST API error: 404, "Not found"

Any ideas? Ty

[danielpopescu]

btw, https://github.com/emacs-mirror/emacs/commit/f2bccae22bd47a2e7e0937b78ea06131711b935a is probably not going away.. so emacs-zmq might need to be fixed to work with this change?

It appears that emacs jupyter doesn't work with jupyter_server >= 2.x release.... Maybe this API change is causing the issue https://github.com/jupyter-server/jupyter_server/pull/1047 ?

[singletS]

I'm also getting "Error in ZMQ subprocess: wrong-type-argument" on linux (debian) GNU Emacs 30.0.50 Development version 57c0549 which pre-dates commit f2bccae by a couple months. This setup used to work fine, but after an update of several melpa/elpa packages now no longer works. Org 9.6.15, juypter-server 2.14.0, emacs-zmq 1.0.0.

[nnicandro]

I believe I have found a fix for the wrong-type-argument error caused by f2bccae which I will push to emacs-zmq when I get the chance.

@danielpopescu As for the REST API error, there may be more information in the notebook buffer. Could you list here the contents of the *jupyter-notebook* buffer that gets created when you specify jupyter-use-zmq to nil.

@danielpopescu I also had a 404 error once on a remote jupyter server I was using (that had password and token disabled). I don't remember the details but it was related to http://jupyterserver:port/login missing when jupyter-api-request-xsrf-cookie was called. I found this by looking at the log of the jupyter server. I solved it like this:

(defun gm/jupyter-api-request-xsrf-cookie-error-advice (func &rest args)
  (condition-case nil
      (apply func args)
    (jupyter-api-http-error nil)))
(advice-add 'jupyter-api-request-xsrf-cookie :around #'gm/jupyter-api-request-xsrf-cookie-error-advice)
