Display "evaluating" status for nodes

[vitvakatu]

In #7435 we implemented displaying "pending" status for nodes.

We also need some indication for the nodes that a currently evaluated by the engine, as evaluating a single node can take several minutes in some cases.

Can we make the icon of the currently evaluating component into a spinner?

Preferably this should work in orchestration with progress API

I see progress field in Pending update. We could display node as being evaluated if progress != 0. If you know better API for this, please let me know.

Yes, that was my idea, when I introduced the progress field. Thus it'd be:

• if there is no progress field, the node is pending and not yet being evaluated
• if there is some value in progress field the node is pending and being evaluated

All that's needed is the IDE to use such info and language server to fill it:

• non-IDE part tracked as API to report progress to the GUI #12009

Thanks!

Refinement notes:

• Do not focus on tracking progress, because it's not implemented in the engine anyway. Just check if > 0.
• May be implemented as spinner in place of node's icon, with cross-fade animation, so there will be no flickering.
