Pull Request resolved: https://github.com/facebook/react-native/pull/46914
The `BridgelessDevSupportManager` should have lived inside the `.devsupport` package alongside all the other
devsupport related tooling.
It was instead created inside `.runtime` causing a tight coupling with `ReactHostImpl`.
This made it impossible for Frameworks to customize it (i.e. in Expo GO) also because there was a circular
dependency between ReactHostImpl and BridgelessDevSupportManager
In this diff I'm:
1. Breaking the circular dependency by using `ReactHostDevHelper`
2. Updating all the parameters to reference `ReactHost` rather than `ReactHostImpl`
3. Moving BridgelessDevSupportManager to the `.devsupport` package.
This is breaking for users that are manually composing a `BridgelessDevSupportManager` or
that are extending the `ReactInstanceDevHelper`.
- `ReactInstanceDevHelper` has 3 new method which will have to be implemented.
- `BridgelessDevSupportManager` is now living in a different package.

Summary:
This PR addresses a potential `ArrayIndexOutOfBoundsException` in the Android module's permission checking logic.
```diff
- results.length > 0 && results[j] == PackageManager.PERMISSION_GRANTED
+ results.length > j && results[j] == PackageManager.PERMISSION_GRANTED
```
It ensures that we only access the results array when the index `j` is within bounds, preventing crashes due to invalid array access that have been occurring in the production environment.
Here is the Crashlytics dashboard concerning this type of crash on my app last week (react-native 0.75.4 - old arch):

## Changelog:
[ANDROID] [FIXED] - Prevent ArrayIndexOutOfBoundsException in permission check
Pull Request resolved: https://github.com/facebook/react-native/pull/47047
Test Plan:
1. Verify normal permission request scenarios still work on Android:
- Request a permission (e.g., camera, location)
- Grant the permission
- Verify the app functions correctly with the granted permission
2. Monitor production crash reports:
- Deploy the fix to production
- Observe a decrease in ArrayIndexOutOfBoundsException occurrences in the permission check logic
Note: As this crash was only observed in production, we'll rely on production monitoring to verify the fix's effectiveness over time.

Pull Request resolved: https://github.com/facebook/react-native/pull/47018
This change makes it so that newly typed text in a TextInput will include the existing attributes present based on cursor position. E.g. if you type after an inner fragment with blue text, the next character will be blue (or, an event emitter specific to an inner fragment will also be expanded). This is a behavior change for the (admittedly rare) case of uncontrolled TextInput with initially present children AttributedText, but more often effect controlled components, before state update (we are after, less likely to need to reset AttributedString because of mismatch).
Originally included this in D64121570, but it's not needed to fix the common case since we include paragraph-level event emitter as part of default attributes, and has some of its own risk, so I decided it is better separate.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46970
Fixes https://github.com/facebook/react-native/issues/44157
This one is a bit of a doozy...
During auto-correct in UITextField (used for single line TextInput) iOS will mutate the buffer in two parts, non-atomically. After the first part, after iOS triggers `textFieldDidChange`, selection is in the wrong position. If we set full new AttributedText at this point, we propagate the incorrect cursor position, and it is never restored.
In the common case, where we are not mutating text in the controlled component, we shouldn't need to be setting AttributedString in the first place, and we do have an equality comparison there currently. But it is defeated because attributes are not identical. There are a few sources of that:
1. NSParagraphStyle is present in backing input, but not the AttributedString we are setting.
2. Backing text has an NSShadow with no color (does not render) not in the AttributedText
3. Event emitter attributes change on each update, and new text does not inherit the attributes.
The first two are part of the backing input `typingAttributes`, even if we set a dictionary without them. To solve for them, we make attribute comparison insensitive to the attribute values in a default initialized control. There is code around here fully falling back to attribute insensitive comparison, which we would ideally fix to instead role into this "effective" attribute comparison.
The event emitter attributes being misaligned is a real problem. We fix in a couple ways.
1. We treat the attribute values as equal if the backing event emitter is the same
2. We set paragraph level event emitter as a default attribute so the first typed character receives it
After these fixes, scenario in https://github.com/facebook/react-native-website/pull/4247 no longer repros in new arch. Typing in debug build also subjectively seems faster? (we are not doing second invalidation of the control on every keypress).
Changes which do mutate content may be susceptible to the same style of issue, though on web/`react-dom` in Chrome, this seems to not try to preserve selection at all if the selection is uncontrolled, so this seems like less of an issue.
I haven't yet looked at old arch, but my guess is we have similar issues there, and could be fixed in similar ways (though, we've been trying to avoid changing it as much as possible, and 0.76+ has new arch as default, so not sure if worth fixing in old impl as well if this is very long running issue).

Looking at the videos from the E2E tests, it seems that the tests are pretty reliable aside from the first one that often fail. And it looks like it is failing not because the test is wrong, but because maestro hits some sort of timeout and kills the test sooner.

- giving more time to maestro to run
- not killing the emulator anymore

[GENERAL] [FIXED] - Fix KeyboardAvoidingView not aware of the keyboard closing it is unmounted
Pull Request resolved: https://github.com/facebook/react-native/pull/46952
Test Plan:
Code to reproduce in RNTester:
```JSX
import type {RNTesterModuleExample} from '../../types/RNTesterTypes';
import {Button, KeyboardAvoidingView, Text, TextInput, View} from 'react-native';
import {Fragment, Suspense, useState} from "react";
const infiniteThenable = { then() {} };
function Suspender({ freeze, children }) {
if (freeze) {
throw infiniteThenable;
}
return <Fragment>{children}</Fragment>;
}
function Freeze({ freeze, children }) {
return (
<Suspense>
<Suspender freeze={freeze}>{children}</Suspender>
</Suspense>
);
}
function Playground() {
const [isFrozen, setIsFrozen] = useState(false);
return (
<>
<TextInput style={{ height: 100 }} />
<Button title="Freeze" onPress={() => setIsFrozen(true)} />
<Button title="Unfreeze" onPress={() => setIsFrozen(false)} />
<Freeze freeze={isFrozen}>
<KeyboardAvoidingView behavior="padding" style={{ flex: 1 }}>
<View style={{ backgroundColor: '#909090', flex: 1, alignItems: 'center', justifyContent: 'flex-end' }}>
<Text>Test</Text>

);
}
export default ({
title: 'Playground',

render: (): React.Node => <Playground />,

```
### Steps
1. Tap the text input to show the soft keyboard.
2. Tap Freeze.
3. Tap the Enter or Done button on the soft keyboard to hide it.
4. Tap Unfreeze.
5. Verify that there is no blank area at the bottom of the screen.
