Alex Hunt c937439e87 Add a basic Jest test to helloworld (#51534)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51534

Aims to give us CI coverage of React Native's Jest preset, preventing future bugs like https://github.com/facebook/react-native/pull/51525.

Changes:
- Add a basic "it renders" Jest test to helloworld
- Add "Run Helloworld tests" step to `test-ios-helloworld` job in CI
- Also convert helloworld's `App.tsx` to TypeScript, as easiest way to unblock Jest JSX behaviour.

Alex Hunt 0acd0828aa Delete helloworld CLI tests (#51533)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51533

Motivation:

- These fail, when ran from `packages/helloworld/` with the available `jest.config.js` file.
- These aren't currently run in CI.
- Don't seem high value (only covers `set-version` behaviour).

In the next diff, I will be adding a missing basic ReactTestRenderer test.

Phil Pluckthun 480a4642e5 fix: Align TimerManager sequential ids and function error handling with web standard (#51500)
Summary:
Calls to create timers should return sequential ids (integers greater than zero in the spec's words). This regressed in the `TimerManager` implementation, which instead starts at zero inclusively.

This has two side-effects for code assuming a spec-compliant implementation of `setTimeout` and `setInterval`:
- Calls to `clearTimeout(0)` or `clearInterval(0)` will potentially cancel scheduled timers, although it's supposed to be a noop
- Predicates like `if (timeoutId)` will fail since they assume non-negative ids

The change in this PR is to align with WHATWG HTML 8.6.2 (Timers): https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#timers

> otherwise, let id be an [implementation-defined](https://infra.spec.whatwg.org/#implementation-defined) integer that is **greater than zero** and does not already [exist](https://infra.spec.whatwg.org/#map-exists) in global's [map of setTimeout and setInterval IDs](https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#map-of-settimeout-and-setinterval-ids).

Specifically,
- we should return `0` to indicate that no timer was scheduled
- we should start generating timer IDs at `1` instead of `0`

This was previously raised in review comments here: https://github.com/facebook/react-native/pull/45092/files#r1650790008

The spec-incompliant behaviour was raised in an issue here: https://github.com/apollographql/apollo-client/issues/12632#issue-3075269978

This PR does not,
- add bounds checking on `timerIndex_` and add a search of an available id that isn't in the unordered map
- exclude `0` from being an accepted `TimerHandle` in `TimerManager::createTimer` or `TimerManager::deleteTimer` since the above bounds checking hasn't been added either

## Changelog:

[GENERAL] [FIXED] - Align timer IDs and timer function argument error handling with web standards.

Pull Request resolved: https://github.com/facebook/react-native/pull/51500

Test Plan:
- Run `setTimeout` / `setInterval`; before applied changes the timeout for the first timer will be `0`
- Run `setTimeout(null)`; before applied changes the timer ID will be non-zero
- Run `setInterval(null)`; before applied changes an error will be thrown rather than `0` being returned

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50585

# Changelog: [Internal]

Replaces `DOMHighResTimeStamp` alias completely in `ReactCommon` with `HighResTimeStamp`.

`DOMHighResTimeStamp` as a type is now expected to be used only in JavaScript.

I didn't update places where we explcitly use `std::chrono::high_resolution_clock`, since it is platform-specific and there is no guarantee that `std::chrono::high_resolution_clock` == `std::chrono::steady_clock`.

Also, places that are isolated and not part of the Web Performance APIs, such as Telemetry for Fabric, are not updates as part of this diff. Although these subsystems are also using `std::chrono::steady_clock` as a low-level representation, they are not sharing it with other parts of the React Native core.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51454

# Changelog: [Internal]

There are multiple changes:
1. `PerformanceTracer` class, `TraceEvent` struct are moved to `tracing` namespace. These are parts of the Tracing subsystems of the jsinspector, this should bring more clarity and make things more explicit.
2. Added `Timing.h` class which defines conversion logic from `HighResTimeStamp` to absolute units that are expected by CDP.
3. `PerformanceTracer` will receive timestamps for Performance Web API entries in `HighResTimeStamp`.

Also, we will explicilty define a Tracking Clock time origin that will be epoch of the `steady_clock`. This aligns with the approach in Chromium and saves us from aligning custom DOMHighResTimeStamps that can be specified in performance.mark / performance.measure calls: these should not extend the timeline window. I've confirmed that this is the current behavior in Chromium.

Pull Request resolved: https://github.com/facebook/react-native/pull/51455

# Changelog: [Internal]

The main idea is that subsystems who might use a different time origin (the starting point of the whole timeline of events), can use `toChronoSteadyClockTimePoint` method to get raw `std::chrono::steady_clock::time_point` and then offset it by some arbitrary epoch: be it unix time origin or `std::chrono::steady_clock::epoch`.

`fromChronoSteadyClockTimePoint` can be used to convert time stamps from external systems, like Hermes.

Panos Vekris 2a068c6559 add 'as const' annotations in preparation of natural inference rollout in xplat/js [4/n] (#51488)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51488

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 };
...
```

However, this class is used and extended by `react-native-reanimated` in order to provide Layout Animations for Android on the Old Architecture. With all its methods being marked as final, the builds are failing.

This PR restores the possibility to extend `LayoutAnimationController`.

Rubén Norte b1e8729f4d Fix incorrect view flattening when using a specific not fully transparent color (#51379)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51379

Changelog: [General][Fixed] Fix incorrect flattening / non-rendering of views with backgroundColor set to `rgba(255, 255, 255, 127/256)`

Fixes #51378.

## Context

When testing some unrelated things with Fantom is realized that the color for some text that I wasn't explicitly defining was being set to `rgba(255, 255, 255, 127)`, like here:

https://github.com/facebook/react-native/blob/249a24ac756275eadbe3b4df1ff9c974af1671d2/packages/react-native-fantom/src/__tests__/Fantom-itest.js#L540-L542

When digging a bit more about why, I realized that was actually the value for `UndefinedColor`. When looking a bit deeper, I saw that the value for that constant was being set like this:

```
using Color = int32_t;

namespace HostPlatformColor {
static const facebook::react::Color UndefinedColor =
    std::numeric_limits<facebook::react::Color>::max();
}
```

I'm not sure what the logic could've been here:
- Defining it as a value out of bounds for all valid colors? In this case, it's a 32 bit value so all the range of values are actually valid RGBA colors.
- Defining it as a fully opaque white? Seems dangerous for a default because you wouldn't be able to distinguish a explicitly set white color from a non-set color, relevant if you're seeing a white background color in a view on top of another view with any other background color.

The result of this existing logic was actually setting `UndefinedColor` to `rgba(255, 255, 255, 127)` because the alpha channel is defined in the first bits of the value, and `Color` being a signed int with 32 bits, the largest value is `01111....1`, so extracting the first 8 bits, you get 127.

## Changes

This changes the value set for the `UndefinedColor` constant (which is used, among other things, to determine if a view sets a background color, or otherwise could potentially be flattened).

The new value, instead of white with a 127/256 opacity, is black with 0% opacity (or simply the number 0 in `int32_t`).

Rubén Norte 6581c69e10 Fix structuredClone test and added test to clarify behavior in IntersectionObserver (#51476)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51476

Changelog: [internal]

When we added integration of IntersectionObserver in the event loop by default, we changed the timing of the observer notification:
- Before, it was scheduled synchronously from the `observe` call.  That means that, if you schedule another task immediately after the observe call, the order is IO callback then task.
- After, it was scheduled at the end of the current event loop tick. That means that, if you schedule another task immediately after the observe call, the order is task then IO callback.

This change in order wasn't accounted for in the tests for IO (which it's added here) and made a test for `structuredClone` break because it was using incorrect assumptions.

This fixes that test.

Samuel Susla 8d3e971baa introduce an option to drive animations with folly::dynamic (#51470)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51470

changelog: [internal]

To support C++ Native Animated and prevent unnecessary conversion between `folly::dynamic` <-> and `NSDictionary`, a method to apply `folly::dynamic` changes needs to be exposed on RCTMountingManager.

Previously I tried to change existing method `synchronouslyUpdateViewOnUIThread` to take folly::dynamic instead of `NSDictionary`. However this requires a change where we would expose C++ API to Objective-C class only, breaking build system in open source. This approach was backed out in  D74881580.

In this diff, I take an alternative approach and expose two methods to apply animation changes:
- Keep the existing API `synchronouslyUpdateViewOnUIThread` as is. This way, Objective-C Native Animated does not need to change.
- Introduce new method for `[RCTSurfacePresenter schedulerDidSynchronouslyUpdateViewOnUIThread]` which accepts `folly::dynamic`. This is used by C++ Native Animated only
