I've stumbled in an edge case that resulted in having a broken cloud user icon and an empty cloud sketchbook. Steps to reproduce:

• make sure your internet connection is ON
• sign in to cloud from the cloud sketchbook
• make sure you have pulled at least one sketch (e.g.: sketch_A)
• turn OFF your internet connection
• open a sketch from the cloud sketchbook that you already had pulled (e.g. sketch_A)
• a new sketch window opens showing the cloud sketch
• 🐛 in the left sidebar, the user image is broken (I guess we should have a default image to show when we can't show the actual user image)
• 🐛 the cloud sketchbook is empty

I'm not sure what the expected behaviour should be here. If possible I guess we should load the cloud sketchbook in the same state as it is in the current window, but I'm not sure we can do that.

@kittaakos thoughts?

UPDATE:
I went a little further and turned back on the internet connection and this is the result:

As you can see, when the connection comes back, the situation doesn't change. Clicking on the "Refresh" button will have the cloud sketchbook loaded, but the user image will still remain unavailable.

Another thing I stumbled into, but I'm not sure it's an unexpected behaviour or if I am missing something about the expected behaviour:

In the following 2 screen recordings, I'm pushing sketches from my local sketchbook to the cloud sketchbook.

The first one results in a different behaviour from the the second one, asking for user's confirmation before pushing the sketch, and after that opening the pushed sketch in a new window.

The second one doesn't ask for confirmation and doesn't open the sketch in a new window:

I'm not sure about the confirmation message, but in the second recording I think it's expected to open the pushed sketch in a new window.

• 🐛 in the left sidebar, the user image is broken (I guess we should have a default image to show when we can't show the actual user image)

I added a patch and the default account codicon is visible when loading the avatar has failed.

I'm not sure about the confirmation message, but in the second recording I think it's expected to open the pushed sketch in a new window.

Thanks! I could reproduce it when creating a cloud copy without renaming the local sketch. The problem was in ncp, so I switched to a new lib and added a few tests.

@91volt, can you please help with the review? Thanks!

Thank you @kittaakos for addressing my comments.

I performed another run of tests and these are the results:

• ✅ this is fixed (now it always asks for confirmation before pushing a sketch)

Thanks for the review!

I expected it would be OK. What is your expectation?

I suggest removing the confirmation prompt when copying a sketch to the cloud, as it may cause confusion for the user since there is no existing sketch being overwritten. Additionally, both options currently result in the same outcome.

About this:

Ideally, this glitch wouldn't exist at all, or the sketchbook would be refreshed automatically in such cases. If fixing it now is time-consuming, we could consider publishing a separate fix for this bug since it is not critical for the general purpose of this feature in my opinion.

About this, I agree with the last comment from @91volt ⬇️

I too was thinking it would be a good idea to remove it. In the end, it's not possible to push a local sketch if it already exists in the cloud, therefore it doesn't make much sense to warn the user saying that "Pushing this Sketch will overwrite its Cloud version."

Thanks! I fixed it

Technically, there is. There is no such thing as create a sketch with these files endpoint. IDE2 has to create a default one and push the local files, so it's not an atomic operation. I tame IDE2 to ignore the arduino.cloud.push.warn preference for this use case.

It's done ✅

Thanks to all of you for the excellent reviews.
