When multiple transitions update the same queue, only the most recent one should be allowed to finish. We shouldn't show intermediate states.

See #17418 for background on why this is important.

The way this currently works is that we always assign the same lane to all transitions. It's impossible for one transition to finish without also finishing all the others.

The downside of the current approach is that it's too aggressive. Not all transitions are related to each other, so one should not block the other.

The new approach is to only entangle transitions if they update one or more of the same state hooks (or class components), because this indicates that they are related. If they are unrelated, then they can finish in any order, as long as they have different lanes.

However, this commit does not change anything about how the lanes are assigned. All it does is add the mechanism to entangle per queue. So it doesn't actually change any behavior, yet. But it's a requirement for my next step, which is to assign different lanes to consecutive transitions until we run out and cycle back to the beginning.

The way this currently works is that we always assign the same lane to all transitions. It's impossible for one transition to finish without also finishing all the others.

Oh I didn’t realize this was already fixed (albeit in a coarse way). Still, we do currently show all of them as “busy”, right — and that would need to be fixed too? Just to confirm the behavior I saw in the demo makes sense.

Correct, the multiple pending spinners issue needs a separate fix

Is the root !== null check here really necessary? Shouldn't Flow prevent that from ever being the case within this function?

Yeah good catch, I copy pasted this from the hooks file where the type wasn't already refined

I want to make sure I understand the new logic for calling markRootEntangled.

The only other place we do this now (I think) is in mutable source. The trigger in that case is when we detect reading from a source that has pending mutations scheduled.

I think the added calls to markRootEntangled are there to ensure that every transition scheduled for the same state/reducer queue get entangled.

I'm not sure I understand why we need to explicitly remove already finished entangled lanes (things no longer in pendingLanes). I understand why we shouldn't re-entangle them but I'm not sure I get why they'd still be in queue.lanes.

I understand why we shouldn't re-entangle them but I'm not sure I get why they'd still be in queue.lanes.

Yeah good question. The lanes field is a superset of all the transition lanes that are still pending on that queue. We don't clear it in the commit phase, we only clear it here and if the hook bails out. Neither of those heuristics will account for all cases, there will be some cases where we don't know for sure if a lane is still pending in the queue, but it's good enough for the common case, which is that there are no pending transitions on the root at all.

It's basically the same trick we use for eagerly bailing out of state updates.

An important detail is that this is the "shared" queue, not the per-fiber queue. When we schedule updates on it, we don't know the current state. It's append-only, you can't read from it. Except with tricks like this.

Entangle overlapping transitions per queue (facebook#20670)
069e7b6 
When multiple transitions update the same queue, only the most recent
one should be allowed to finish. We shouldn't show intermediate states.

See facebook#17418 for background on why this is important.

The way this currently works is that we always assign the same lane to
all transitions. It's impossible for one transition to finish without
also finishing all the others.

The downside of the current approach is that it's too aggressive. Not
all transitions are related to each other, so one should not block
the other.

The new approach is to only entangle transitions if they update one or
more of the same state hooks (or class components), because this
indicates that they are related. If they are unrelated, then they can
finish in any order, as long as they have different lanes.

However, this commit does not change anything about how the lanes are
assigned. All it does is add the mechanism to entangle per queue. So it
doesn't actually change any behavior, yet. But it's a requirement for my
next step, which is to assign different lanes to consecutive transitions
until we run out and cycle back to the beginning.
