cl-jupyter unresponsive "issue with UTF-8 decoding"? #45

Closed stereosphere closed 5 years ago

stereosphere commented 5 years ago

Hello,

I am using SBCL 1.3.1.debian on Ubuntu 16.04. I have updated all my quicklisp dists.

I start in a terminal with "jupyter notebook".

When I load "about-cl-jupyter.ipynb", the kernel does not respond to evaluation requests. I get an asterisk in the brackets. I get the following message in the terminal:

[I 15:54:13.959 NotebookApp] Kernel started: 6459a13b-4f46-4935-911f-123f13f80457 To load "cl-jupyter": Load 1 ASDF system: cl-jupyter ; Loading "cl-jupyter" ..................

Hello, I put a print statement after (bordeaux-threads:release-lock message-recv-lock) in the message-recv function in message.lisp. It's never called, so it looks like there is a hang up there. I'm going to switch from Firefox to Chrome to see if that makes a difference.

Works on Chrome! Next I'm going to try to get cl-jupyter-widgets working.
