The proposed solution is to call `RCTApplyBaselineOffset` separately for each line of text.
Ideally, we would call it separately for each part of text with different font size.

The Flow team is improving the way Flow infers type for primitive literals.
Announcement: https://fb.workplace.com/groups/flowlang/permalink/1725180268087629/
This diff prepares the codebase for the new behavior by codemoding `as const` annotations.
## Repro steps
1/ Used steps in D73610163 to produce the code changes.
2/ Reverted files where `flow` errored:
```
flow status --show-all-errors > errors.log
node ~/fbsource/fbcode/flow/facebook/error-analyzer.js errors.log |
awk -F':' '{ print $1 }' | sort -u | grep -v 'Total Error Count' |
xargs hg revert --rev .
```
3/ Reverted files that did not improve error count in new Flow mode
```
# Run Flow before change
~/fbsource/fbcode/flow/facebook/flowd status --show-all-errors > errors-0.log
# Run Flow after change
~/fbsource/fbcode/flow/facebook/flowd status --show-all-errors > errors-1.log
# Compute error counts before and after
node ~/fbsource/fbcode/flow/facebook/error-analyzer.js errors-0.log | sort > errors-counts-0.log
node ~/fbsource/fbcode/flow/facebook/error-analyzer.js errors-1.log | sort > errors-counts-1.log
# Revert files with no change in error count
comm -12 errors-counts-0.log errors-counts-1.log | awk -F':' '{ print $1 }' | xargs hg revert --rev .~1
```
## Note to code owners
Due to the large number of errors involved in this rollout, adding `as const` was the most feasible large-scale automated solution. Ideally, a lot of these errors would be fixed by adding other appropriate type annotations. For example instead of annotating
```
type Shape = {type: 'circle', radius: number} | {type: 'square', side: number} | ...;
type ShapeKind = 'circle' | 'square' | 'triangle';
const circle = {
type: "circle" as const, // <-- annotation added here
radius: 42,
};
shape.type as ShapeKind;
takesShape(circle);
```
a more appropriate annotation would be
```
const circle: Circle = { type: "circle"; radius: 42 };
...
```

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51452
Changelog: [internal]
This implements a long planned refactor of `IntersectionObserver` to have a proper integration with the Event Loop, which unblocks `FragmentRef` in React Native.
The existing integration doesn't integrate with the Event Loop, so the intersection determination doesn't happen as a step in the event loop but in 2 different moments:
1. When you start observing a new target, we check if there are any pending transactions for that target, and otherwise determine the intersection immediately and queue the notifications.
2. Using mount hooks, when a transaction for a surfaceId is mounted, we check intersections for all the observers in that surface.
This has an important problem:
* If you attach a observer on a target before the target is attached to the tree (something that `FragmentRef` will start doing soon), we don't have a pending transaction so we determine intersections immediately. In that case, it's always "not visible" because it's not attached, and then we immediately trigger a transition when mounted in the same tick.
To fix this, we can implement a step in the Event Loop the same way that `IntersectionObserver` does on Web. We would still wait for pending transactions to be mounted to determine intersection timing (the same way we do now, but now checking at the end of the current Event Loop tick), but the dispatch of initial notifications for target that won't change is done at the end of the tick instead of synchronously.
It also refactors the list of active observers as a list of shared pointers to `IntersectionObserver` objects, instead of as list of `IntersectionObserver` objects directly. This is necessary to build the list of pending observers (with stable references) while making sure the ownership stays in the list of active observers.

The script will now try to resolve and download a prebuilt version of hermes:
1. Hermes artifacts will be extracted to the `./build/artifacts/hermes` folder to ensure that Package.swift can find a version to link against.
2. The script checks the environment variable `HERMES_ENGINE_TARBALL_PATH` and tries do expand the tarball into the artifacts folder from 1
3. If not found, the script reads the hermes version from either the hidden environment-variable `HERMES_VERSION` and tries to download a release-tarball or a nightly tarball for this version. If the version does not exist, the script will fail.
Also added some extra logging features to the script.

We process a number of props by default in View, so we can provide some amount of compatibility with web API's. The way we then pass these to React means we end up setting a number of props with 'undefined' values. These props need to be diffed, sent to native (so string keys copied via JSI) and serialized to folly::dynamic (on Android) which is just wasteful.
Instead we can mutate the destructured props object and update/insert keys only as necessary to reduce the props payload size.
Changelog: [General][Breaking] View no longer sets any default accessibility props, which should not result in visible changes in behaviour but may affect snapshot tests.

Pull Request resolved: https://github.com/facebook/react-native/pull/51303
We do a lot of incorrect `cei()` in text measurement, compensated later by other incorrect bits.
There are a couple of interesting bits here:
A "desired width" is how large a hypothetical text layout would like to be. It is a floating point value, and to avoid truncation, a container must be larger than the desired width. So ceiling this is correct.
We are also passed available width, which may be an exact specification, not at a subpixel boundary. Ceiling this is totally incorrect, since Yoga will disregard our ceiled version, and we just created a layout, larger than our actual measure will be.
We must instead floor `availableWidth`, and we create our layout based off of that, to not give an extra physical pixel, that may not be given to us, if later layout rounding doesn't go our way. We then ceil `desiredWidth` earlier.
Finally, when we have an exact measuremode, we create the layout so that it uses guaranteedWidth`, but act as if it takes the full available space, per-contract, which may be a subpixel size larger. This means we cannot create layouts which cause truncation.
I used this change as an opportunity to clean up `createLayout()`, since we are gating anyways, to remove the duplicated paths, and to avoid the unnecessary `TextDirectionHeuristic` work for BoringLayout case, and since `StaticLayoutBuilder` already defaults to the heuristic we are manually setting.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51206
When we create a layout from measure constraints, we do some processing of the width, to return a different one, potentially smaller than the layout width, sometimes using line width, and sometimes using the container width.
This logic has gotten spooooky over time, and after a series of changes, and bugfixes, now effectively does nothing!
1. Way back in 2020, yungsters made D21056031 introducing this logic to "shrink wrap" text which is wrapped.
2. "Shrink wrapping" is not how web works when text is wrapped, (though it is how it works when there is explicit newline), and https://github.com/facebook/react-native/pull/47435 later undid this change
3. https://github.com/facebook/react-native/pull/37790 made changes specific to the case of trailing newline, because the logic to "shrink wrap" did not handle correctly.
After D74366936, which changes width used for layout creation to correctly respect `Layout.desiredWidth`, we should be back to multiline layouts, with no paragraph whose lines take up more than container width, being "shrink wrapped", while not doing so when there is wrapping or ellipsization, like current behavior. The desired width also excludes the non-visible trailing whitespace.
It means we can remove all of this logic, while preserving the same behavior. Mismatched measure widths from those used in the intermediate layout may also result in issues for Facsimile (see example in last diff of stack).

Summary:
Selectively disabling autolinking of a native dependency with components registered in the codegen configuration in react-native.config.js causes builds to crash upon launch on iOS. This is because the generated `RCTThirdPartyComponentsProvider.mm` file contains references to the excluded library using `NSClassFromString` causing the returned NSDictionary from `+[RCTThirdPartyComponentsProvider thirdPartyFabricComponents]` to be populated with nil values and therefore crashing the app. This has been confirmed in 0.78.2 and 0.79.2 but probably exists in 0.77.x as well.
The issue has been further described in https://github.com/facebook/react-native/issues/51077.

This adds infrastructure to let us start storing cached Android text layouts as part of a `ParagraphShadowNode`. After this, we will clear them out, and propagate them to state. Right now, the flag doesn't do much, apart from extra work.
This is done by adding `TextLayoutManagerExtended::supportsPreparedLayout()`, and `TextLayoutManager::PreparedLayout` types, to shim between platforms, then on Android, we add a `PreparedLayout`, which is for now just an Android layout, with extra field (`maxNumberOfLines`, for some reason not exposed on recent versions).
Android `TextLayoutManager` java side is split a little bit, so that we reuse all the existing logic for prepared layouts. I tried to set up the boundary, so that we don't reserialize a MapBuffer after preparation, and for simplicity, this means source of truth for attachment count, and attachment sizes, now lives on the layout. This means we need to change boundary a bit, where we are no longer able to pass in a buffer to fill from C++ side of attachment positions.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50997
In some apps, we spend a non-trivial amount of time calling ShadowNode destructors on the UI thread.
A simple way to avoid stalling the UI thread is to move the `baseRevision_` instance to a data structure that is cleared on a background thread, so it's tree of ShadowNode shared_ptrs are released (and in most cases destroyed) on the background thread.
Rather than using std::thread, this change introduces the LowPriorityExecutor abstraction that should be supplied by host platforms. The implementation of this LowPriorityExecutor for each platform is as follows:
- iOS: uses dispatch_async to a low priority dispatch queue
- Android: uses a pthread with SCHED_OTHER and priority = 19
Moving the ShadowTreeRevision into a lambda capture and punting the lambda to the LowPriorityExecutor moves the destructor calls of the ShadowNodes to the host platform implementation of the LowPriorityExecutor.
This change is also guarded by a feature flag so we can keep an eye out for potential memory leaks.

Pull Request resolved: https://github.com/facebook/react-native/pull/51040
## Resubmit
We were previously only checking for `maxNumberOfLines` of `ReactConstants.UNSET` (-1), but it may also be `0` to signify unset from other checks (wut), and different versions of Android would handle this case of `maxLines={0}` differently.
The resubmission adds an explicit check for zero here as well.
```
if (ReactNativeFeatureFlags.incorporateMaxLinesDuringAndroidLayout()) {
if (maxNumberOfLines != ReactConstants.UNSET && maxNumberOfLines != 0) {
builder.setEllipsize(ellipsizeMode).setMaxLines(maxNumberOfLines);
}
}
```
## Previous
Right now, we fully layout text, then use max lines to determine a metric to use when calculating size.
Android API 23+ which we fully target allows incorporating ellipsization and maxlines directly into the layout. This will let us directly draw the layout when using maxLines later. This may also let Android optimize line-breaking a bit, when we hit truncation.
Special care is taken not to set this when we are in `adjustsFontSizeToFit` path, so that line count will flow over, signifing overflow.
I think the main user-facing change is that `onTextLayout` events will have measures post-ellipsization.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50855
This diff addresses a crash caused by view duplication in React Native Android. The issue occurred when a view was not already clipped and was laid out again, resulting in duplicated views.
This problem was particularly noticeable when using nested FlatLists, which triggered a custom focus search with an incomplete and buggy duplicated FlatList container view.
The fix involves preventing the duplication of views by checking if a view is clipped already before laying it out again. Additionally, this diff includes two other improvements:
- Preventing clipping issues: When a view is nested within a non-ReactClippingViewGroup ancestor, focus searching would fail due to the needUpdateClippingRecursive logic only running on instances of ReactClippingViewGroup. By excluding these ancestors, we ensure that the next focusable view can be properly excluded from being clipped.
- Minor fix: A minor fix was made to prevent potential issues in deeply nested cases.
- Add a Kill switch with a feature flag and mobile config combo.

Summary:
Some libraries still use the `folly_flags` method provided by our infra. When updating how folly should be installed in an app, we removed that function.
We are putting it back as deprecated, to avoid unnecessary breaking changes in libraries
## Changelog:
[iOS][Fixed] - Put back the `folly_compiler_flag` function to make libraries install pods
Pull Request resolved: https://github.com/facebook/react-native/pull/50875
Test Plan: Tested locally in a nightly app, using the react-native-exit-app library which still uses these flags
