Joshua Gross b637b21f09 LayoutAnimations: don't animate root ShadowNode mutations
Summary:
Root nodes doesn't have a ComponentDescriptor that can be looked up via this mechanism, and we probably shouldn't be animating Root nodes anyway (?). This is a debug-only assert but could be causing issues in production.

The fix is simple - just don't animate any changes to a root node.

Summary:
Changelog: [internal]

There is a possibility of race between updating scrollview's state and virtualised list asking for layout of individual cells.
To make sure the race doesn't happen, state must be updated before dispatching onScroll event.

Android has implemented a different mechanism to tackle this issue in D28558380 (https://github.com/facebook/react-native/commit/b161241db2ef74d2e4bff36d4972f5f0312dcc44).

Special case: `onScroll`, which is always treated as "Default".

Joshua Gross 5a9b6fc49b Simplify LockFreeEventDispatcherImpl further
Summary:
TL;DR: simplify and delete a bunch of stuff that shouldn't be necessary in Fabric.

I discovered that this event dispatcher (and the older one this is based on) is triple-queueing: we queue events into "staging", and then post "dispatch events" to only run /on the JS thread/. Even in Fabric. Then, each of these events is emitted into C++ where they are queued /again/! This refactor eliminates one more level of queueing - instead of scheduling dispatch for the JS thread, we just emit them directly to C++ when they're received in Java.

Unfortunately, the EventDispatcher is also used to drive AsyncEventBeat in C++:

1. EventBeatManager.onBatchEventDispatched: https://fburl.com/diffusion/qf6dyhsw
   In the C++ impl, it indirectly will drive the AsyncEventBeat/AsyncEventBeatV2.
2. onBatchEventDispatched is ONLY called from EventDispatcherImpl: https://fburl.com/codesearch/mxk8ifyj
3. Which is queued and only runs on the JS thread: https://fburl.com/codesearch/czvbst4u

This means the AsyncEventBeat is only ticked when the JS thread is free, and ticks will be skipped when the JS thread is occupied for long periods.

Now, in this refactor, when this class is used it will drive AsyncEventBeat on every UI tick. This is also potentially not correct. On iOS (Fabric), AsyncEventBeat is driven when the UI thread is "about to sleep".

For now I'm not going to worry about that detail - it is significant, but Fabric+Android is currently /not doing the right thing/ and it's not clear that we want to maintain iOS behavior. This is something we need to discuss further and figure out.

Andrew Coates 7aeac4236f Move isColorMeaningful to platform specific code (#31557)
Summary:
`isColorMeaningful` is the only place in xplat code that currently uses `colorComponentsFromColor`, which assumes that a color is an RGBA value.  When implementing `PlatformColor` for windows, where colors might be complex patterns or effects, I'd like to keep the details of `SharedColor` isolated within `SharedColor`.  This change moves `isColorMeaningful` into `color.cpp`, where each platform can provide an implementation that takes into account its platform specific color capabilities.

See https://github.com/microsoft/react-native-windows/pull/7801 for an example of window's SharedColor which can be either an RGBA value, or a name of a native color/brush.

Samuel Susla ffa533a19d Add option to use unbatched queues only
Summary:
Changelog: [internal]

My suggestion is to simplify event dispatching to only two options, synchronous and asynchronous.

Why?
- Fabric has only been using one queue, `AsynchronousBatched`.
- Batching happens even on `AsynchronousUnbatched`. It just batches events until JS thread starts processing them instead of waiting for the main run loop.
- It will make it easier to reason about the code in the future once we start utilising different priorities for Concurrent Mode.

This first batch generates a random mutation, then animates it to completion.

I found one issue with UPDATE+REMOVE+INSERT animation consistency. That shouldn't cause any crashes in production, but is a chance to improve consistency of mutations overall - and could in theory point to memory corruption, though it's somewhat unlikely.

I ran with randomized seeds, found issues, fixed them, re-ran to ensure issues were fixed, rinsed and repeated. At the end I was able to run dozens of times (with random seeds) and found nothing.

The next step is to repeatedly generate mutations that conflict with ongoing animations.

Kacie Bawiec da899c0cc4 Add support for Toggle Button accessibilityRole
Summary:
Changelog:
[General][Added] Add support for "togglebutton" accessibilityRole

# Context
The role for ToggleButton, which is needed on Android to implement toggle buttons correctly, is not currently supported.

# What does this diff do?
Adds support for accessibilityRole `"togglebutton"`.

On Android, this maps to class `"Android.widget.ToggleButton"`.

iOS does not have an equivalent trait for togglebutton, so I set it to be the same as setting `accessibilityRole="button"` for iOS.

# Caveats - checked vs selected
It seems to me like this role currently requires that you set `accessibilityState={{checked: true/false}}`. The behavior is strange when setting `selected` state, I think because on Android ToggleButtons are meant to use `checked` to indicate toggled on/off.

This is tricky because typically on iOS if you have a toggle button, you would use `selected` instead of `checked`, so RN users are likely to mess this up.

Possible solutions:
1. document that you should use `checked` state on Android for toggle buttons (and maybe throw a warning if someone passes in `selected`).
2. have RN ignore it if someone passes in accessibilityState `selected`, if this role is used.
3. Have RN convert passed in `selected` state to `checked` on the Android side.

Ramanpreet Nara 7e05480cc3 Delete @synthesize turboModuleRegistry API in RCTTurboModule
Summary:
All NativeModules/TurboModules can use the following Venice-compatible API instead:
```
synthesize moduleRegistry = _moduleRegistry
```

In bridge mode, it'll look up the module via the TurboModule system/bridge.
In bridgeless mode, it'll look up the module via the TurboModule system.

Therefore, there's no need to support this API.

Summary:
Changelog: [internal]

state infra uses rvalue references until this point. I assume the original author intended to rvalue reference even here.
This way, we avoid unnecessary copy.

Joshua Gross 119e8f4cd8 Differ: in flattening/unflattening nested case, reduce code duplication
Summary:
Refactor a code block that is duplicated 2x. Logic stays the same besides renaming, and a ternary operator to decide between getting the children from "old" or "new" tree.

Tests can help us refactor knowing that the logic is still correct.

Joshua Gross 1e68a5f573 Differ: simplify nested flattening/unflattening code
Summary:
There's a case here where we do a loop, with a map loopup, and nested map lookup inside of that. It's not particularly efficient and was done because we have multiple distinct pointers to distinct ShadowViews that are backed by the same ShadowNode. Now due to previous, recent refactoring, we can simplify this case a lot.

The code WAS correct before, just confusing and not particularly efficient. Tests can prove that this is still correct.

Joshua Gross 7131791ab1 Differ: dedupe more code in main differ loop
Summary:
I am deduping a duplicated block, and adding comments to explain when we create INSERT/REMOVE mutations immediately and when we defer creation.

Theoretically the ordering of mutations will be more consistent now, which ~shouldn't matter, but is probably a decent property to have. In particular, before, in some cases
both of these orderings were possible in various scenarios:

```
INSERT X -> Y
INSERT Y -> Z
```

and

```
INSERT Y -> Z
INSERT X -> Y
```

Both of those are fine/correct/won't cause issues on any known platforms. But now, at least for the two cases touched here, only this ordering will be produced:

```
INSERT Y -> Z
INSERT X -> Y
```

meaning we build the tree from the bottom-up (the "bottom" being the root) and do out-of-order inserts less frequently.

Again, the biggest part of this diff should be readability/refactoring/de-duplicating logic, but more consistent orderings is a nice-to-have.

Joshua Gross ca3aae7980 Differ: fix unit test case 1167342011
Summary:
Unit test case seed 1167342011 encodes a case where the differ produces a DELETE and CREATE of the same node in the same frame, which we consider an error.

It turns out this was caused by nested "unflatten" operations and this bit of deleted code specifically. We were deleting an unmatched node from a parent call's dictionary of nodes,
which prevented it from being matched in the "old" tree later on.

This is only possible now that we attach pointers to the "other" ViewNodePair when they're matched, so we can check existence of that pointer instead of inclusion in dictionaries to decide if we need to DELETE/CREATE a node and its subtree.
