Description

When I set the recordTimings option to be true with

{
    "recordTiming": true
}

in the user preferences for the notebook, the "execution timings" get outputted to the cell metadata, but the kernel doesn't seem to actually execute the cell. For example, print("hello world!") won't print, 1+1 won't output 2, and the cell reports jibberish as having evaluated normally instead of causing an error.

Reproduce

  • Set recordTiming to be true and save
  • try any simple output in a notebook

Expected behavior

Notebook should run normally when execution timings are active.

Context

  • Operating System and version: Windows 10
  • Browser and version: Chrome
  • JupyterLab version: 2.0.1

Returning false prevents the message from being processed by the future or by any other hook, which messes everything up.

I reproduced this with stock jlab 2.0.1 as well.

jasongrout added a commit to jasongrout/jupyterlab-execute-time that referenced this issue Apr 8, 2020
There was a bug in JLab 2.0.0 and 2.0.1 that prevented cell execution when recordTiming was enabled. You might be able to cut down on support issues if you just go ahead and require at least JLab 2.0.2.

See jupyterlab/jupyterlab#8057 and jupyterlab/jupyterlab#8056
