`Specify local or remote Jupyter server for connections` broken

Issue Type: Bug

Communicating the migration instructions after factoring out Jupyter extension from the Python extension has been ham-handed. among others: https://github.com/microsoft/vscode-jupyter/issues/1057

It is not at all clear that to get to the pop-up selection menu to input a new server in the <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>p</kbd> menu, input Jupyter: Specify local or remote Jupyter server for connections.

If I select Jupyter: Specify local or remote Jupyter server for connections, even if its the same server it is already connected to, VS Code will force me to reload/restart VS Code. If I don’t restart and select Jupyter: Specify local or remote Jupyter server for connections again, I get a VS Code ERROR:

Command ‘Jupyter: Specify local or remote Jupyter server for connections’ resulted in an error (command ‘jupyter.selectjupyteruri’ not found)

Also, how can I delete urls from the list of recently used servers+tokens? It is keeping a list of all of the Jupyter servers that have long since been shut down.

Is it possible to specify the server in the .code-workspace settings like I used to before the Jupyter extension was factored out of the Python extension? It was much more convenient to simply specify “python.dataScience.jupyterServerURI”: “http://100.100.100.001:8888/?token=*******************” in the settings.

Why was the python.dataScience.jupyterServerURI setting not ported over to the Jupyter extension as jupyter.jupyterServerURI along with most of the other python.dataScience settings?

Is there any way to view this setting?

The only way to view the setting is to bring up the ‘Specify local or remote Jupyter server for connections’ picker. It will show the current value at the top:

We should probably have a ‘what’s changed’ in the release notes that describes what’s changed.

I can do a brief summary here:

• All python.dataScience settings are now jupyter. settings except for one exception
• python.dataScience.jupyterServerURI has been removed. You can no longer set this in your settings.json. It’s encrypted now. You have to use the command above.
• In the VS Code insiders version, we will default to using the new native notebook support. See https://devblogs.microsoft.com/python/notebooks-are-getting-revamped/ and the blog post that came out with the new jupyter extension: https://devblogs.microsoft.com/python/python-in-visual-studio-code-november-2020-release/

As far as I remember that should be the sum total of the differences. I’ll add a bug to put this in our release notes (and or documentation)

We’re also planning on revamping the remote support. Something more akin to this is coming: https://github.com/microsoft/vscode-jupyter/issues/1366
