Based on #17483

Refactors legacy update queue to incorporate rebasing fix. Uses nearly the same approach as the hook update queue but has to handle a few other cases.

Managed to remove some older, poorly factored code related to error handling.

To-do

  • One remaining unit test to fix
  • Fix Flow

What's this about, we need this for it to stay circular, no? Maybe we're missing a test?

All I did was remove the first !== null check. Which is unnecessary because update.next is never null.

I think the diff makes it look like I deleted the assignment but really all I deleted was the type check that surrounds it.

Actually, to rephrase, it's not really a type check that I deleted. In the old implementation, the queue was only sometimes circular. It would eventually "unravel" to linear so that the old nodes could be garbage collected. But in the new implementation, the pending queue is always circular. So you don't need to check for if it's circular or not.

I looked into this for a while and I think the old version was just wrong and it accidentally worked with the old implementation. I'm going to try to write a failing test for what's in master.

Never mind, I found the bug. Will add a test.

Adds a failing test case where an update that was committed is
later skipped over during a rebase. This should never happen.

Why is this an array as opposed to a linked list like the hooks form? Harder to see how they correlate.

I was considering a refactor to arrays but with a different take (inline fields instead of objects) . However, I wanted to do that as a separate refactor.

Idk I just chose one :D

This felt like a different trade off from the hooks one because these effects are relatively rare. Only when you pass a callback to setState. It's more like the emitEffect API.

So it didn't seem worth putting a nextEffect field on the update type

This test passes in the old legacy update queue implementation. I'm
adding this before the refactor to prevent a regression.
Refactors legacy update queue to incoporate rebasing fix. Uses nearly
the same approach as the hook update queue but has to handle a few
other cases.
acdlite added a commit that referenced this pull request Dec 9, 2019
Fixes a bug related to rebasing updates. Once an update has committed,
it should never un-commit, even if interrupted by a higher priority
update. The fix includes a refactor of how update queues work.

This commit is a combination of two PRs:

- #17483 by @sebmarkbage refactors the hook update queue
- #17510 by @acdlite refactors the class and root update queue

Landing one without the other would cause state updates to sometimes be
inconsistent across components, so I've combined them into a single
commit in case they need to be reverted.

I squashed this with the hooks refactor and landed as b617db3 so it can be atomically reverted.

* Initialize update queue object on mount

Instead of lazily initializing update queue objects on the first update,
class and host root queues are created on mount. This simplifies the
logic for appending new updates and matches what we do for hooks.
