Right now, when a 3p library needs to register a component in the component system, we have to crawl the library to try and get the mappng, best effort.
With this approach, we are enriching the `codegenConfig` property to allow library developers to define the mapping themselves.
For example:
```json
//...
"codegenConfig": {
//..
"ios": {
"componentProvider": {
"RNTMyNativeView": "RNTMyNativeViewComponentView"
}
}
},
```
means that the JS component `RNTMyNativeView` will be mapped to the `RNTMyNativeViewComponentView` class.
This also work for local apps, and it warns the users about what libraries are using the deprecated approach, so they can open an issue or a PR to those libraries.

Pull Request resolved: https://github.com/facebook/react-native/pull/47518
This change reintroduce the generation of the `RCTThirdPartyComponentProvider` but in the right place and with the right patterns.
1. We are generating it in the user space, not in the node_modules (fixes the circular dependency)
2. We are not using weak function signature that have to be implicitly linked to some symbols found during compilation
The change needs to crawl the folder to retrieve the information it needs. We need to implement it this way not to be breaking with respect of the current implementation.
The assumption is that components have a function in their `.mm` file with this shape:
```objc
Class<RCTComponentViewProtocol> <componentName>Cls(void)
{
return <ComponentViewClass>.class;
}
```
I verified on GH that all the libraries out there follow this pattern.
A better approach will let library owner to specify the association of `componentName, componentClass` in the `codegenConfig`.
We will implement that as the next step and we will support both for some versions for backward compatibility.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47517
The `RCTThirdPartyLibraryComponentProvider` has been introduced to automate the component registration of third party libraries in the apps. However, it has some serious flaws:
* It is generated in the React/Fabric folder, which means that it is generated in node_modules
* It is generated when the user installs the components in the app, which means that we can't prebuild and redistribute React Native as a binary
* it does not work with Frameworks and dynamic linking: in this scenarion, Fabric must build in isolation and if there are third party libraries involved, the lookup of the `xxxCls` function will fail
This change removes the generation of the `RCTThirdPartyLibraryComponentProvider`. In the next diffs we will implement a different mechanism to register components

RuntimeExecutor, RuntimeScheduler, etc. can execute arbitrary c++ on the javascript thread.
If that c++ throws a non-jsi::JSError, it will bypass the js error handler (and start tearing down the react instance 😱).
Let's have the js error handler manage all exceptions raised while native is calling into js. This is more sane.

Across our scroll view implementations on iOS, we fire `onMomentumScrollEnd` whenever the scroll view finishes decelerating, whether it comes from a user's touch or call to `setContentOffset` with animations. But we omit dispatching the `onMomentumScrollBegin` event in the latter cases.
This change updates both old and new architecture to dispatch `onMomentumScrollBegin` when a view-command-driven scroll occurs with animation, like `scrollTo` or `scrollToEnd`.

This race condition only shows itself with flag `useOptimizedEventBatchingOnAndroid`
# Problem
EventBeat assumes method `induce` will be called repeatedly on every UI tick. This is true for iOS and existing implementation of event beat on Android. The first early exist inside of `induce` method is built with this assumption.
`useOptimizedEventBatchingOnAndroid` on Android changes this. `induce` will only be called after FabricUIManager.onRequestEventBeat is invoked and then it will stop. For one `FabricUIManager.onRequestEventBeat` call, `EventBeat::induce` is called once. And there is a chance for race condition.
Here is a simplified implementation of `induce`. This method may be called many times in sequence. The caller will set [isRequested_](https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/renderer/core/EventBeat.cpp#L25) and then invoke [FabricUIManager.onRequestEventBeat](https://github.com/facebook/react-native/blob/main/packages/react-native/ReactAndroid/src/main/jni/react/fabric/AndroidEventBeat.cpp#L43). Notice how `FabricUIManager.onRequestEventBeat` is debounced if `isRequested_` flag is true.
```
void EventBeat::induce() const {
if (!isRequested_ || isBeatCallbackScheduled_) {
// isRequested_ is not set to false in case isBeatCallbackScheduled_) is true.
return;
}
isRequested_ = false;
isBeatCallbackScheduled_ = true;
auto beat = std::function<void(jsi::Runtime&)>(
// on JS queue
isBeatCallbackScheduled_ = false;
// beatCallback_(runtime)
}
runtimeScheduler_.scheduleWork(std::move(beat));
}
```
This can get into a state where `isRequested_` is not reset back to false even though `EventBeat::induce` is called when `isBeatCallbackScheduled_` is true.
`AndroidEventBeat::request` -> `isRequested_` is set to true -> `FabricUIManager::onRequestEventBeat` -> `EventBeat::induce` -> `isRequested_` is set to false -> `isBeatCallbackScheduled_` is set to true -> `AndroidEventBeat::request` -> `FabricUIManager::onRequestEventBeat` -> `EventBeat::induce` (early exit because `isBeatCallbackScheduled_` is true) -> `beat` is executed on the JS thread.
From this point on, subsequent calls to `AndroidEventBeat::request` are always debounced because flag `isRequested_` is true.
Any subsequent event on Android will end up calling `EventBeat::induce` and the mechanism gets unstuck.
# The fix
The fix is simple, any time `EventBeat::induce` is called, make sure `request_` flag is set to false. This then satisfied the expectation of `useOptimizedEventBatchingOnAndroid` optimisation.

When we have multiple spans of text inside a <Text> element, React will emit these as separate RawText ShadowNodes. RawText shadow nodes cannot have any properties beyond the text they contain, yet our current AttributedText logic will generate a separate span for each and duplicate all the relevant properties.
This can be particularly inefficient when JSX is used to interpolate strings, e.g. `<Text styles={styles.text}>Example {i}/{count}</Text>` results in 4 raw text elements with duplicated properties.
