Scenario (general):
1.1 Start code-server:
WORKON_HOME=~ code-server --cert --cert-host 172.30.15.137 --disable-telemetry --disable-update-check ~/_railcars
2.1 Open https://172.30.15.137:8080 in Google Chrome
3.1 Open Untitled.ipynb, run three cells: import pandas, create DataFrame, sum dataframe values
4.1 Close / Do not close code-server tab in Chrome
4.2 Check output in terminal
5.1 Kill code-server with Ctrl+C
5.2 Check output in terminal
6.1 Check ps -ef output for hanging processes
7.1 Check ~/.local/share/jupyter/runtime for left kernel and nbserver files
8.1 kill -9 hanging processes, clear files in runtime folder
Scenario 1: keep ~/.local/share/code-server/extensions/ms-toolsai.jupyter-<VER>/pythonFiles/lib/python/pyls_jsonrpc, close tab in (4.1)
Results:
4.2) The client has disconnected gracefully ... Process exited with code: 0
5.2) (no output)
