The "Close and Shut Down Notebook" menu command discards state without confirmation

[stanwest]

Problem

When I have a notebook open and select "Close and Shut Down Notebook" from the "File" menu of the notebook interface, notebook (as of v. 7.3.0a0) closes the kernel unconditionally, discarding the computational state. I recommend that the interface confirm that the user wants to close and shut down, as JupyterLab does (at least in v. 4.3.0a0) when one selects its "Close and Shut Down Notebook…" menu item.

Proposed Solution

Restore the confirmation dialog and add an ellipsis to the end of the text in the menu item.

Additional context

This behavior seems to have arisen in #7384.

Hi @stanwest . I am new to open-source and want to contribute to this issue . @stanwest I came across this code snippet for close and shut down -> execute: async () => { // Shut the kernel down, without confirmation await commands.execute('notebook:shutdown-kernel', { activate: false }); window.close(); } in the packages/notebook-extension/src/index.ts path . To this problem

const confirmation = confirm('Are you sure you want to close the notebook and shut down the kernel?'); if (confirmation) { await commands.execute('notebook:shutdown-kernel', { activate: false }); window.close(); }
would this be a right approach ? thoughI have not tested it yet .

I would highly appreciate your input,

Thanks .

From Triage: The reason why @JasonWeill implemented this as is was for Notebook 6 parity. If you'd like to have this behavior, it would need to be implemented as a configuration option.

The reason why @JasonWeill implemented this as is was for Notebook 6 parity.

Thank you for triaging this and commenting. I understand and agree that parity has some weight, and yet I believe it would be much better for Notebook to ask the user if they really do want to lose state.

If you'd like to have this behavior, it would need to be implemented as a configuration option.

I don't follow that it must be that way, but if it were an option, I would recommend that the default be to ask for confirmation. Users who want no confirmation as in v. 6 could set the option accordingly.

Hi @jtpio, i would like to contribute to this issue and plan to start working on it. Please let me know if there are any specific guidelines or things i should be aware of.

@sai-chand04 here are the contributing guidelines: https://github.com/jupyter/notebook/blob/main/CONTRIBUTING.md

Please feel free to open a PR when you have something, even if it's not fully finished and still a draft.

Looks like the idea in this idea would be to implement a setting to allow for showing the dialog and allow for the behavior before #7384.

Thanks!

Thank you for the guidance! I have started working on allowing the dialog to show and restoring the behavior before #7384. I will open a PR soon, even if it's still in draft form, for initial feedback.

Thanks!
