Notebook: Read-only notebooks can't be unlocked for editing

[PrinterOperator]

This issue is open in the ipython project here, and it doesn't appear like it's been migrated to jupyter.

As mentioned in that thread, it would be great to either have a "Save As" feature or to not allow editing of a read-only file.

Has there been any further work on this?

I accidentally extensively edited a notebook that was read-only on the disk and my changes are permanently lost it seems; despite having the window open I can find no mechanism other than copying and pasting every cell to save my changes, even after the notebook is made writable on the disk.

I had a file on disk with read-only permissions and I modified it to be able it to be written but I was still not able to save my notebook after extensive edits. As a workaround, using the web browser debugger, I put a break point in Notebook.prototype.save_notebook and set this.writable = true. I was then able to save the notebook and retain my changes.

@gnestor @takluyver I noticed that the copy handler does accept a 'to_path', but the POST calls from contents.js on the client side only set the copy_from. Would you be open to accepting a PR for the Save as feature ?

I'm thinking of adding a modal that lets the user enter a path, checks if the user has permissions to write to that path and if so, save it there.

This would be great for copying shared read-only notebooks as well.

Yes, I think so. There's a PR here, but it seems to have stalled: https://github.com/jupyter/notebook/pull/3071

This is still an issue.

Is someone working on this?
Else I will implement this myself, with inspiration from: https://github.com/pangeo-data/helm-chart/pull/44#issuecomment-399151464
