Now that interleaved updates are added to a special queue, we no longer need to shift them into their own lane. We can add to a lane that's already in the middle of rendering without risk of tearing.

See #20615 for more background.

I've only changed this in the new fork, and only behind the enableTransitionEntanglements flag.

Most of this commit involves updating tests. The "shift-to-a-new" lane trick was intentionally used in a handful of tests where two or more updates need to be scheduled in different lanes. Most of these tests were written before startTransition existed, and all of them were written before transitions were assigned arbitrary lanes.

So I ported these tests to use startTransition instead, which is the idiomatic way to mark an update as parallel.

I didn't change the old fork at all. Writing these tests in such a way that they also pass in the old fork actually revealed a few flaws in the current implementation regarding interrupting a suspended refresh transition early, which is a good reminder that we should be writing our tests using idiomatic patterns as much as we possibly can.

nit SomeTransitionLane seems like a weird name. Is there a reason you went with "some" instead of e.g. "first"?

I guess this parallels SomeRetryLane.

Yeah first is probably better. I was indeed taking a naming cue from SomeRetryLane.

Okay that we just removed this guarantee (even when the feature flag is disabled)?

Yeah the guarantee is now maintained in the work loop instead, so this function can do whatever it wants. (Also why I changed the verb to "claim", to imply that it's not pure.)

Don't shift interleaved updates to separate lane

Now that interleaved updates are added to a special queue, we no longer
need to shift them into their own lane. We can add to a lane that's
already in the middle of rendering without risk of tearing.

See facebook#20615 for more background.

idiomatic way to mark an update as parallel.

I didn't change the old fork at all. Writing these tests in such a way
that they also pass in the old fork actually revealed a few flaws in the
current implementation regarding interrupting a suspended refresh
transition early, which is a good reminder that we should be writing our
tests using idiomatic patterns as much as we possibly can.

Don't shift interleaved updates to separate lane (facebook#20681)
a19d28a 
Now that interleaved updates are added to a special queue, we no longer
need to shift them into their own lane. We can add to a lane that's
already in the middle of rendering without risk of tearing.

See facebook#20615 for more background.

I've only changed this in the new fork, and only behind the
enableTransitionEntanglements flag.

Most of this commit involves updating tests. The "shift-to-a-new" lane
trick was intentionally used in a handful of tests where two or more
updates need to be scheduled in different lanes. Most of these tests
were written before `startTransition` existed, and all of them were
written before transitions were assigned arbitrary lanes.

So I ported these tests to use `startTransition` instead, which is the
idiomatic way to mark an update as parallel.

I didn't change the old fork at all. Writing these tests in such a way
that they also pass in the old fork actually revealed a few flaws in the
current implementation regarding interrupting a suspended refresh
transition early, which is a good reminder that we should be writing our
tests using idiomatic patterns as much as we possibly can.
