| test('update during an interleaved event is not processed during the current render', async () => { |
There was a problem hiding this comment.
We already have a smattering of tests that cover these cases but they were kinda old and mostly pre-hooks, so I wrote these extra ones. Duplicative but still helpful when refactoring.

## Motivation An *interleaved* update is one that is scheduled while a render is already in progress, typically from a concurrent user input event. We have to take care not to process these updates during the current render, because a multiple interleaved updates may have been scheduled across many components; to avoid tearing, we cannot render some of those updates without rendering all of them. ## Old approach What we currently do when we detect an interleaved update is assign a lane that is not part of the current render. This has some unfortunate drawbacks. For example, we will eventually run out of lanes at a given priority level. When this happens, our last resort is to interrupt the current render and start over from scratch. If this happens enough, it can lead to starvation. More concerning, there are a suprising number of places that must separately account for this case, often in subtle ways. The maintenance complexity has led to a number of tearing bugs. ## New approach I added a new field to the update queue, `interleaved`. It's a linked list, just like the `pending` field. When an interleaved update is scheduled, we add it to the `interleaved` list instead of `pending`. Then we push the entire queue object onto a global array. When the current render exits, we iterate through the array of interleaved queues and transfer the `interleaved` list to the `pending` list. So, until the current render has exited (whether due to a commit or an interruption), it's impossible to process an interleaved update, because they have not yet been enqueued. In this new approach, we don't need to resort to clever lanes tricks to avoid inconsistencies. This should allow us to simplify a lot of the logic that's currently in ReactFiberWorkLoop and ReactFiberLane, especially `findUpdateLane` and `getNextLanes`. All the logic for interleaved updates is isolated to one place.

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.

…book#20615) ## Motivation An *interleaved* update is one that is scheduled while a render is already in progress, typically from a concurrent user input event. We have to take care not to process these updates during the current render, because a multiple interleaved updates may have been scheduled across many components; to avoid tearing, we cannot render some of those updates without rendering all of them. ## Old approach What we currently do when we detect an interleaved update is assign a lane that is not part of the current render. This has some unfortunate drawbacks. For example, we will eventually run out of lanes at a given priority level. When this happens, our last resort is to interrupt the current render and start over from scratch. If this happens enough, it can lead to starvation. More concerning, there are a suprising number of places that must separately account for this case, often in subtle ways. The maintenance complexity has led to a number of tearing bugs. ## New approach I added a new field to the update queue, `interleaved`. It's a linked list, just like the `pending` field. When an interleaved update is scheduled, we add it to the `interleaved` list instead of `pending`. Then we push the entire queue object onto a global array. When the current render exits, we iterate through the array of interleaved queues and transfer the `interleaved` list to the `pending` list. So, until the current render has exited (whether due to a commit or an interruption), it's impossible to process an interleaved update, because they have not yet been enqueued. In this new approach, we don't need to resort to clever lanes tricks to avoid inconsistencies. This should allow us to simplify a lot of the logic that's currently in ReactFiberWorkLoop and ReactFiberLane, especially `findUpdateLane` and `getNextLanes`. All the logic for interleaved updates is isolated to one place.

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.

Motivation
An interleaved update is one that is scheduled while a render is already in progress, typically from a concurrent user input event.
We have to take care not to process these updates during the current render, because a multiple interleaved updates may have been scheduled across many components; to avoid tearing, we cannot render some of those updates without rendering all of them.
Old approach
What we currently do when we detect an interleaved update is assign a lane that is not part of the current render.
This has some unfortunate drawbacks. For example, we will eventually run out of lanes at a given priority level. When this happens, our last resort is to interrupt the current render and start over from scratch. If this happens enough, it can lead to starvation.
More concerning, there are a surprising number of places that must separately account for this case, often in subtle ways. The maintenance complexity has led to a number of tearing bugs.
New approach
I added a new field to the update queue,
interleaved. It's a linked list, just like thependingfield. When an interleaved update is scheduled, we add it to theinterleavedlist instead ofpending.Then we push the entire queue object onto a global array. When the current render exits, we iterate through the array of interleaved queues and transfer the
interleavedlist to thependinglist.So, until the current render has exited (whether due to a commit or an interruption), it's impossible to process an interleaved update, because they have not yet been enqueued.
In this new approach, we don't need to resort to clever lanes tricks to avoid inconsistencies. This should allow us to simplify a lot of the logic that's currently in ReactFiberWorkLoop and ReactFiberLane, especially
findUpdateLaneandgetNextLanes. All the logic for interleaved updates is isolated to one place.Rollout plan
This is a moderately risky change, so I'm going to land this only in the new fork.
I'll wait until after the effects refactor has landed.
In this first PR, I've implemented the new queueing behavior, but I haven't yet cleaned up any of the old logic we used to rely on to address the same problem. Cleaning that stuff up is the main motivation for this change, but it introduces additional risk. So I'll follow up with a separate PR, in case there's a bug and we need to bisect.
