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: - facebook#17483 by @sebmarkbage refactors the hook update queue - facebook#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. Co-authored-by: Sebastian Markbåge <sema@fb.com> Co-authored-by: Andrew Clark <git@andrewclark.io>
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.

I don't think this should be on |

That makes sense but I didn't want to deal with the ramifications of other stuff that reads from it. Like DevTools. At least right now. |

Basically I'm trying to keep the scope of this "bugfix" somewhat narrow. Can do a fuller refactor later. |

Can update be changed while inside the loop? Do we need to additionally check for not null being inside if (update !== null)?

Good catch. It's missing a update = update.next line at the end of the loop. Honestly I don't think anyone actually uses this method anymore, so I'll probably just remove it.

Yeah, I believe removal would be safe here and in the block below.

Same question whether pendingUpdate needs to be checked for ! == null when already inside if check
