Bug Description

Not so long ago a very useful feature was implemented which enables deleting tracks while in the track drawing mode. While in track drawing mode you push delete to delete a track segment and backspace to delete the whole track up to the nearest pad or via (there was a separate bug report here Unfortunately it is still not working properly. If the track is within another footprint extents or next to another footprint, pressing DEL or Backspace deletes the track segment or the whole track (which is correct behavior) but at the same time it deletes the footprint as well (which is not suppose to happen) If you hit undo you can reverse deleting the footprint while the track remains deleted. So you can eventually get the the desired result, it just takes several steps.

@Seth, did by chance your commit d0ffff3b88 fix this bug or is this something different?

Hmm... What was the expected behavior here?

Currently, d0ffff3b88 just prevents delete from happening while actively routing. I tested and it looks like we can use both delete and alt-delete from within the routing tool as long as you are not actively routing.

I have a patch to allow deleting tracks while routing but it deactivates the full route. I feel like this is not really beneficial as the user would lose their track unexpectedly.

I've looked at ways to allow deletion while keeping the current track but I don't understand the tool framework sufficiently to implement this at the moment. Currently if you allow the delete event to proceed, the PointEditor gets activated, an activation event that stops the routing. I assume that the tool manager is just iterating through tools that tie with interactiveSelection event.

Just skipping the activation events is not a good idea either because then we end up with a partially routed track even when a hotkey has triggered another action (e.g. placing a component).

There's probably a clever solution to this but it escapes me for now.

I don't know that the expected behavior was ever defined only that it worked a certain way and now it acts a different way. Maybe that is the fundamental problem here, we didn't define the behavior so everyone has their own expectations and we have no good response. Before we make any more changes to the route, we should define this behavior first. That's something to discuss during v6 development.
