- Canvas manages its own progress socket event listeners and progress event data.
- Remove cancellations listener jank.
- Dip into low-level redux subscription API to watch for queue status changes, clearing the last "global" progress event when the queue has nothing in progress. Could also do this in a useEffect I guess.
- Had to shuffle some things around to prevent circular imports, so there are a lot of tiny changes here.
Download events and invocation status events (including progress images) are very frequent. There's no real need for these to pass through redux. Handling them outside redux is a significant performance win - far fewer store subscription calls, far fewer trips through middleware.
All event handling is moved outside middleware. Cleanup of unused actions and listeners to follow.
- New routes to clear, enable, disable and get the status of the cache
- Status includes hits, misses, size, max size, enabled
- Add client cache queries and mutations, abstracted into hooks
- Add invocation cache status area (next to queue status) w/ buttons
