Summary

This Pull Request implements the PlatformColor proposal discussed at react-native-community/discussions-and-proposals#126. The changes include implementations for iOS and Android as well as a PlatformColorExample page in RNTester.

Every native platform has the concept of system defined colors. Instead of specifying a concrete color value the app developer can choose a system color that varies in appearance depending on a system theme settings such Light or Dark mode, accessibility settings such as a High Contrast mode, and even its context within the app such as the traits of a containing view or window.

The proposal is to add true platform color support to react-native by extending the Flow type ColorValue with platform specific color type information for each platform and to provide a convenience function, PlatformColor(), for instantiating platform specific ColorValue objects.

PlatformColor(name [, name ...]) where name is a system color name on a given platform. If name does not resolve to a color for any reason, the next name in the argument list will be resolved and so on. If none of the names resolve, a RedBox error occurs. This allows a latest platform color to be used, but if running on an older platform it will fallback to a previous version.
The function returns a ColorValue.

On iOS the values of name is one of the iOS UI Element or Standard Color names such as labelColor or systemFillColor.

On Android the name values are the same app resource path strings that can be expressed in XML:
XML Resource:
@[<package_name>:]<resource_type>/<resource_name>
Style reference from current theme:
?[<package_name>:][<resource_type>/]<resource_name>
For example:

  • ?android:colorError
  • ?android:attr/colorError
  • ?attr/colorPrimary
  • ?colorPrimaryDark
  • @android:color/holo_purple
  • @color/catalyst_redbox_background

On iOS another type of system dynamic color can be created using the IOSDynamicColor({dark: <color>, light:<color>}) method. The arguments are a tuple containing custom colors for light and dark themes. Such dynamic colors are useful for branding colors or other app specific colors that still respond automatically to system setting changes.

Example: <View style={{ backgroundColor: IOSDynamicColor({light: 'black', dark: 'white'}) }}/>

Other platforms could create platform specific functions similar to IOSDynamicColor per the needs of those platforms. For example, macOS has a similar dynamic color type that could be implemented via a MacDynamicColor. On Windows custom brushes that tint or otherwise modify a system brush could be created using a platform specific method.

…Color PR. (facebook#28040)

Summary:
The [PlatformColor PR](facebook#27908) is currently open to implement the [PlatformColor proposal](react-native-community/discussions-and-proposals#126).   When that PR was imported into Facebooks internal builds it was found that the change to the `processColor()` function to return an opaque type or `number` instead of just `number` breaks internal components.

This PR is a simplification of the PlatformColor PR only changing the return type of `processColor()` from `?number` to `?number | NativeColorType` where `NativeColorType` is just an empty but opaque type.   This will allow changes to be made to these internal components but with less risk than the larger PR.

## Changelog

[General] [Changed] - Add NativeColorType opaque type to normalizeColor() ahead of PlatformColor PR
Pull Request resolved: facebook#28040

Test Plan: Flow checks, Jest test, iOS unit tests, iOS integration tests, and manual testing performed on RNTester for iOS and Android.

facebook-github-bot pushed a commit that referenced this pull request Mar 28, 2020
Summary:
The [PlatformColor PR](#27908) added support for iOS and Android to express platform specific color values.   The primary method for an app to specify such colors is via the `PlatformColor()` method that takes string arguments.   The `PlatformColor` method returns an opaque Flow type enforcing that apps use the PlatformColor method instead of creating Objects from scratch -- doing so would make it harder to write static analysis tools around Color values in the future.   But in addition to `PlatformColor()`, iOS has a `DynamicColorIOS()` method that takes an Object.   The Flow type for this Object cannot be opaque, but we still want to enforce that app code doesn't pass variables instead of Object literals or that values in the Objects are variables.   To ensure `DynamicColorIOS()` can be statically analyzed this change adds an ESLint rule to enforce that `DynamicColorIOS()` takes an Object literal of a specific shape.   A `ColorAndroid()` was also introduced not for practical use but just to test having platform specific methods for more than one platform in the same app.   A second ESLint rule is created for `ColorAndroid` as well.

## Changelog

…28577)

Summary:
This change removes the `ColorAndroid` API.   It was added more as a validation tool than as something useful to a developer.   When making the original [PlatformColor PR](#27908) we felt it was valuable and useful to have working platform specific methods for the two platforms in core to test that the pattern worked in app code (PlatformColorExample.js in RNTester) and that the Flow validation worked, etc.    Practically `PlatformColor()` is more useful to a developer on Android than `ColorAndroid()`.    Now that the construct has served its purpose, this PR removes the `ColorAndroid` function and its related tests and other collateral.

I found this section specially hard to read, so I'm proposing some minor tweaks that I think will make it easier to understand. 

I also added a mention to the fallback values which the function can receive, taking from the original PR which introduced the changes (facebook/react-native#27908)

I don't know what the exact policy is on this, but since this was introduced in RN 0.63.0, perhaps this could also be clarified on the docs, as using it from an older version will throw a `_reactNative.PlatformColor is not a function` error.

* Properly handle LogBox errors during tests

Summary:
This diff fixes an issue where errors in LogBox during tests would cause the tests to crash.

The crash is due to the NativeExceptionsManager module not being mocked (as all native module need to be in tests). The fix is to properly mock the NativeExceptionManger.

This fix exposed an infinite loop issue where failures in LogBox will be logged to the ExceptionManager, which logs to the console, which logs to LogBox, creating a loop. This diff also fixes that look by moving the LogBox internal error check to the top of the monkey patched console methods.

Summary:
Simplifying the dispatchMountItems reentrance and retry logic.

Motivation: cleanup so I can work on dispatching ViewCommands before anything else.

Importantly, this gives us the properties that:
1) Only one function is responsible for calling dispatchMountItems
2) Only one function is responsible for deciding if we shouldn't call dispatchMountItems due to reentrance
3) Only one function is responsible for all cleanup
4) Only one function maintains all of the relevant flags (except dispatchPreMountItems... two total now, instead of 4 before)

Summary:
Earlier this week I introduced a change in the old, non-Fabric renderer (D20378633 D20427803) that (gated behind a feature-flag) executes ViewCommands before all other types of commands, as a perf optimization and (I think) a potential fix for a category of race conditions.

I've added more details in comments here.

* feat: improve monorepo support by removing redundant PROJECT_ROOT (#28354)

Summary:
Historically, React Native didn't support a lot of custom project structures apart from the standard flat directory with `ios` and `android` folders. The CLI had to be explicitly started from the project root, otherwise Metro didn't work right.

In order to resolve the project root in the most accurate way, React Native assumed that project root is always `../../` from its location in `node_modules` - this is not true when the installation gets hoisted (e.g. in a monorepo).

To address that, janicduplessis brought support for custom [`PROJECT_ROOT`](https://github.com/facebook/react-native/commit/9ccde378b6e6379df61f9d968be6346ca6be7ead) that allowed overriding the `../../` in case it wasn't true.

Today, CLI is able to automatically resolve the project root, no matter where it's started. It will traverse the tree of the directories upwards and stop as soon as it meets `package.json`.

As a result, it doesn't really matter from where we start the CLI anymore as a part of `react-native-xcode.sh`.

By replacing the default value of `$REACT_NATIVE_DIR/../../` with `$PWD, that is default for all Xcode scripts, we can make the setup for monorepo easier - nobody will need to set `$PROJECT_ROOT` in order to override the incorrect defaults.

By default, all scripts defined in Xcode run from `$PWD` directory, which is the location of the iOS project. In the future, we will be able to remove `cd` entirely.

To better understand this PR, let's look a few hypothetical structures as an example:

#### Monorepo:

> tl;dr works out of the box, no need to mess around with paths

```
- package.json
- packages/
  - my-app/
     - index.js
     - package.json
     - ios/
        - MyApp.xcodeproj
```

**Before this PR**, the `react-native-xcode.sh` will start the CLI like this:

```bash
cd $REACT_NATIVE_DIR/../../
node <absolute_path_to_cli.js> bundle --entry-point index.js
```

- Because we change the directory to the root of monorepo, CLI throws an error. All in all, there's no `react-native` dependency at the workspace root.

- Some users turn `no hoist` in an act of troubleshooting the errors, which resolves the problem - `react-native` is moved under `my-app/node_modules` which makes this mechanism resolve properly.

- Some users find out about `PROJECT_ROOT` and set it to overwrite the default value. For example, setting `export PROJECT_ROOT = "$PWD/../` will set the directory to `my-app`, which has a dependency on `react-native` in a `package.json` and makes the CLI happy.

**After this PR**, the `react-native-xcode.sh` will start the CLI like this:

```bash
cd $PWD
node <absolute_path_to_cli.js> bundle --entry-point index.js
```

- The `$PWD` is `packages/my-app/ios/` because that's where the Xcode project is located. CLI will automatically set the root to `../` because that's where it finds `package.json` with `react-native` dependency. It will pass that root to Metro, unless users have set a different one themselves. Thanks to that, all paths to JavaScript files remain working and unaffected.

- No need to set `PROJECT_ROOT` anymore.

- We don't rely on the location of `node_modules`, which is cleaner and future proof.

#### Standard:

> tl;dr no changes

```
- ios/
   - MyApp.xcodeproj
- index.js
- package.json
```

**Before this PR**, the `react-native-xcode.sh` will start the CLI like this:

```bash
cd $REACT_NATIVE_DIR/../../
node <absolute_path_to_cli.js> bundle --entry-point index.js
```

- Everything works fine. Path from `react-native` inside `node_modules` is correct - the project root is set right to `/`

**After this PR**, the `react-native-xcode.sh` will start the CLI like this:

```bash
cd $PWD
node <absolute_path_to_cli.js> bundle --entry-point index.js
```

- The root will be set to where Xcode project is located, which is `/ios`. This is the PWD for all Xcode scripts.

CLI will look for the `package.json` going upwards from `ios` folder. Will stop at `/`, find out it has `react-native` dependency, load it and its commands and proceed further.

This fixes two things:

1) Currently it only respects Start and End padding, and if there's a Theme default, it will override Left/Right padding. Whoops.

This resolves both.

It still does not account for RTL support.

1. If `start` and `end` parameters in `setTextAndSelection` are -1, we don't move the cursor. Previously the cursor would be moved to beginning of text input.

This contains a fork of the upstream Flow types. We shouldn't be syncing this since these leads to conflicting types.

As a result, these uses have already been codemodded away. Only the imports remained.

* Fix controlled TextInput with child nodes

Summary:
Changelog: [Internal]

# There are three changes in this diff

## _stateRevision is replaced with a BOOL
`_stateRevision` was protecting against setting attributed string that is already visible to the user. Previously this was ok because the change was only coming from native, any changes from JS were ignored.

Imagine following scenario:

1. User taps key.
2. Update state is called on component initiated by native.
3. New state is created with incremented revision by one.
4. `_stateRevision` gets set to new state's revision + 1.
5. Now JS wants to change something because it just learnt that user tapped the key.
6. New state is created again with incremented revision by one.
7. Update state is called on the component, but the change isn't applied to the text view because `_state->getRevision()` will equal `_stateRevision`.

By having a BOOL instead of number, we very explicitly mark the region in which we don't want state changes to be applied to text view.

## Calling [_backedTextInputView setAttributedText] move cursor to the end of text input
This is prevented by storing what the current selection is and applying it after `[_backedTextInputView setAttributedText]` is called.
This was previously invisible because JS wasn't changing contents of `_backedTextInputView`.

## Storing of previously applied JS attributed string in state

This is the mechanism used to detect when value of text input changes come from JavaScript. JavaScript sends text input value changes through props and as children of TextInput.
We compare what previously was set from JavaScript to what is currently being send from JavaScript and if they differ, this change is communicated to the component.
Previously only first attributed string send from JavaScript was send to the component.

# Problem

If children are used to set text input's value, then there is a case in which we can't tell what source of truth should be.

Let's take following example
We have a text field that allows only 4 characters, again this is only a problem if those 4 characters come as children, not as value.
This is a controller text input.

1. User types 1234.
2. User types 5th character.
3. JavaScript updates TextInput, saying that the content should stay 1234.
4. In `TextInputShadowNode` `hasJSUpdatedAttributedString` will be set to false, because previous JS value is the same as current JS value.

* Fix Animated Value initialized with undefined in ScrollView (#28349)

Summary:
When passing an object to contentOffset that doesn't have `y` prop set it causes the following error:

```
 Error: AnimatedValue: Attempting to set value to undefined

This error is located at:
    in ScrollView (at src/index.js:638)
...
```

This happens since a runtime check was added to the `AnimatedValue` constructor. (a3aaa471eca58b31597b9a0669f7ade385ccb175)

According to flow types the object passed to contentOffset should always contain both x and y props but since it worked before when y is undefined I think its fine to patch the runtime behaviour defensively, especially since the code change is simple.

This PR adds an entry to SSH’s `known_hosts` file using github.com’s public key that I have verified as per [these instructions](https://serverfault.com/a/807363):

```

```

These fingerprints line up with [the ones posted by GitHub](https://help.github.com/en/github/authenticating-to-github/githubs-ssh-key-fingerprints), so my setup should be good and can be trusted to grab the public key from the right host:

* De-jank DevLoadingView

Summary:
## Problems
Repro steps:
1. Disable Fabric (because CMD + R doesn't work with Fabric right now).
2. Open up Marketplace and hit `CMD + OPT + R`
3. **Observe:** The progress bar doesn't show up right away. It also doesn't actually show progress.
https://pxl.cl/140g1

RN Support post: https://fb.workplace.com/groups/rn.support/permalink/3437652016283389/

## Fixes
The first problem is that progress bar doesn't actually show progress.

**Fix:** Bundle load progress is updated in `RCTCxxBridge`, where we first require `RCTDevLoadingView`, and then call its `updateProgress` method. Previously, we wouldn't  lazily load `RCTDevLoadingView`, it already didn't exist. Lazily loading `RCTDevLoadingView` causes the progress view to show up. Here: https://pxl.cl/140gt

If you look at the above video, you'll notice there are two stages to the progress bar: stage 1 displays the actual progress. Stage 2 prompts that we're downloading the JS bundle. As you can see, stage 1 and stage 2 have different background colors, even though both of them are green.

**Fix:** I adjusted the JS to match the Native color. Here: https://pxl.cl/140gT

We're almost there, but the progress bar is dismissed twice?

**Fix:** I dug into the code, and the reason why was because when we hit `CMD + R`, we invalidate the bridge, and immediately re-initialize it. This means that we asynchronously invalidate the old TurboModuleManager, and immediately create a brand new one. Therefore, two `RCTDevLoadingView` modules can (and do) exist at once. So, I moved `RCTDevLoadingView` to be an instance member of `FBReactModule`, to ensure that it doesn't get cleaned up and re-created when TurboModuleManager is deleted and re-created. This finally fixed the progress bar jank:

* ✅ Green CI: Fix JavaScript e2e tests, disable failing Android e2e test (#28392)

Summary:
Jobs now have a `run_disabled_tests` argument that allows for the selective execution of disabled tests. When working on re-enabling a failing test, the contributor just needs to set `run_disabled_tests` to `true` in the appropriate workflow in `.circleci/config.yml`.

Tests can be kept green by moving failing tests into the disabled section until a contributor can provide a fix, thus ensuring signal is maintained on master. For example, a failing end-to-end test might be disabled in order to allow the signal from unit tests to be provided, as opposed to flat out failing the entire job.

What was done in this PR:
* The failing `test_js_e2e` job has been fixed, and merged into the `test_js` job. An empty disabled tests section is added for future use.
* The failing `test_ios_e2e` job has been merged into `test_ios`, with all of its steps gated behind the `run_disabled_steps` argument.
* The failing Android end-to-end tests have been added to `test_android`, gated behind the `run_disabled_steps` argument
* The failing Podspecs test has been added back into `test_ios`, gated behind the `run_disabled_steps` argument

* Fabric: Fixing a deadlock in RCTSurfacePresenter

Summary:
This is another attempt to fix an issue very similar to T59424871. The previous attempt was in D19249490. I don't know why we don't see production crashes (stalls) but it happened to me (and not to me) in the debugger. The previous attempt didn't work because we still could have a deadlock because we tried to acquired shared mutex already owned exclusively by the `suspend` method.

Here is another approach: Instead of using one shared mutex, now we use two. One is similar to what we had and another that protects `suspend` and `resume`. Besides that, now we pass a Scheduler to functions that use that explicitly. This way we can be more explicit about acquiring mutexes and the overall flow of execution. The idea is: Now an arbitrary code that can be reentrant does not cover with mutexes, so the deadlock is not possible.

* Make ScrollView use ForwardRef

Summary:
Have ScrollView use forwardRef so that the host component methods like `measure` and `measureLayout` are available without having to call `getNativeScrollRef`. Instead, you can use `<ScrollView ref={myRef} />` and directly call all methods of ScrollView and host components on `myRef`.

Previous usage:
```
const myRef = React.createRef<React.ElementRef<typeof ScrollView>>();
<ScrollView ref={myRef} />

const innerViewRef = myRef.current.getNativeScrollRef();

innerViewRef.measure();
```
New usage:
```
const myRef = React.createRef<React.ElementRef<typeof View>>();
<ScrollView ref={myRef} />

// now, myRef.current can be used directly as the ref
myRef.current.measure();
myRef.current.measureLayout();

// Additionally, myRef still has access to ScrollView methods
myRef.current.scrollTo(...);
```

Changes:

* Added deprecation warnings to ScrollView methods `getNativeScrollRef`, `getScrollableNode`, and `getScrollResponder`
* Added the forwardRef call to create `ForwardedScrollView` - this takes in `ref` and passes it into the class ScrollView as `scrollViewRef`.
* Forwarded the ref to the native scroll view using `setAndForwardRef`.
* Added statics onto `ForwardedScrollView` so that `ScrollView.Context` can still be accessed.
* Added type `ScrollViewImperativeMethods`, which lists the public methods of ScrollView.
* Converted all public methods of ScrollView to arrow functions. This is because they need to be bound to the forwarded ref.
* Bound all public methods of ScrollView to the forwarded ref in the `setAndForwardRef` call.
* Flow typed the final output (ForwardedScrollView) as an abstract component that takes in the props of the `ScrollView` class, and has all methods of both the inner host component (`measure`, `measureLayout`, etc) and the public methods (`scrollTo`, etc).

Changes to mockScrollView:
* Changed mockScrollView to be able to mock the function component instead of a class component
* Updated necessary tests

* Optimize diff algorithm to produce fewer remove+insert ("move") paired instructions

Summary:
An evolution of D20633188 but more performant.

There are three optimized paths before the slow path.

The first optimized path tries to pair identical nodes from old/new tree, and generate Update mutations, until we hit nodes that are different (indicating either a remove or an insert). This already existed.

The next two optimizations, introduced by Tim in his JS pseudocode, were inspired by ReactJS's diffing algorithm. They work in cases where the rest of the nodes are (1) all removals/deletes or (2) all creates+inserts.

Finally, if those final two optimized paths can't run, it's because there is a mix of delete+remove, create+insert, and "move" operations, mixed at the beginning, middle, and/or end of the list.

This has slightly better average/best-case complexity as the previous implementation.
In particularly pathological cases where all nodes are arbitrarily reordered, or reversed, for instance (ABCDE->EDCBA) the algorithm has the same complexity as the previous algorithm (quadratic).

For now iOS is pinned to the older differ

* Add ES Lint rules for `DynamicColorIOS()`and `ColorAndroid()` (#28398)

Summary:
The [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) added support for iOS and Android to express platform specific color values.   The primary method for an app to specify such colors is via the `PlatformColor()` method that takes string arguments.   The `PlatformColor` method returns an opaque Flow type enforcing that apps use the PlatformColor method instead of creating Objects from scratch -- doing so would make it harder to write static analysis tools around Color values in the future.   But in addition to `PlatformColor()`, iOS has a `DynamicColorIOS()` method that takes an Object.   The Flow type for this Object cannot be opaque, but we still want to enforce that app code doesn't pass variables instead of Object literals or that values in the Objects are variables.   To ensure `DynamicColorIOS()` can be statically analyzed this change adds an ESLint rule to enforce that `DynamicColorIOS()` takes an Object literal of a specific shape.   A `ColorAndroid()` was also introduced not for practical use but just to test having platform specific methods for more than one platform in the same app.   A second ESLint rule is created for `ColorAndroid` as well.

* fix: Android gradle config when bundling for release (#28415)

Summary:
This fix aims to address the issue when bundling an Android app for release and getting the error exhibited in https://github.com/facebook/react-native/issues/28002 which I also encountered myself.

The config was changed sometime in November 2019 (as part of https://github.com/facebook/react-native/issues/26940, commit https://github.com/facebook/react-native/commit/a3b08048674e324dbe1f0ca816f35607e9e06a2f) to be very opinionated when it comes to the use of `npx` which Gradle itself cannot find anyway (I have `npx` installed globally and it didn't pick it up).

Another issue that the use of `npx` creates is that Gradle should only ever use the currently installed react-native cli rather than a (possibly) higher version which may not always have backward compatibility.

The proposed change simply throws a more descriptive error rather than defaulting to a tool which may or may not exist on the machine, be it CI or a development environment. I've also modified the RNTester app to reflect the correct config implementation relative to the RNTester app itself.

In real projects, the config inside `android/app/build.gradle` should look similar to the following snippet:

```
project.ext.react = [
  cliPath: "$rootDir/../node_modules/react-native/cli.js",
  entryFile: "index.js"
];
```

* Reimplement D19965405: Small improvements in Differentiator/TinyMap

Summary:
Two things:
1) I reimplement Valentin's idea in D19965405, so that TinyMaps can be iterated over, with a couple of bugfixes (calling front() or back() on an empty vector will crash).
2) I now use TinyMap instead of better::map in the "optimized" diffing algorithm.
3) `erase` now actually removes elements from the vector, but only when more than half of elements have been erased.
4) If you repeatedly erase elements at the beginning of the vector, they will no longer be iterated over. This is a specific optimization for our heaviest TinyMap use-cases.

These amount to some small but hopefully somewhat meaningful perf improvements.

* Remove LayoutInspectingPolicy.includeScrollViewContentOffset

Summary:
`LayoutInspectingPolicy` has two flags, `includeTransform` and `includeScrollViewContentOffset`.

`includeScrollViewContentOffset` seems to be redundant for two reasons.

# 1st
From looking at callers, they have always the same value.
I looked at all call sites, and they are either always both set to true or both set to false.

# 2nd
The way we include scroll view content offset, is through transformation, so setting `includeTransform` to true and `includeScrollViewContentOffset` to false will include content offset anyway. In order to make both flags work, we would need to introduce further changes to `getRelativeLayoutMetrics`. But since the flag isn't used anyway, I think it is better to get rid of it for now. If we need it in the future, we could re-introduce it.

So if you had a view which has width and height 100 and had `Scale(0.5, 0.5, 1)` (this will shrink view by half). Calling `getRelativeLayoutMetrics` would report its size being `{100, 100}`.
This applies if view's parent has transformation as well, because transformation is applied to all subviews of the view as well.

* Enable inspector for Fabric

Summary:
## Overview
This diff refactors the Inspector, moving logic to look up view data for a touched view inside the renderer as `getInspectorDataForViewAtPoint`. We then implement that same function for Fabric in order to support the inspector in that renderer.

Requires https://github.com/facebook/react/pull/18388

## Motivation

Reason one for this refactor is that, previously, the inspector held all of the logic to look up view data for a given x,y touch coordinate. To do this, it would take the React tag and coordinates, look up the native view tag, measure it, and then ask React internals for the Fiber information of that tag. All of this is deeply coupled to React internals, yet the logic is outside of React core in the Inspector.

Reason two is that, for Fabric, the logic for getting the view data is different than Paper. In Fabric, we pass the x,y coordinates to native directly, which returns an instance handle. That handle can be used to measure the ShadowNode, or retrieve the Fiber information.

By moving the logic into the renderer in React core, we decouple the implementation details of looking up view data for a tapped point and allow ourselves the ability to add and change renderer-specific code for the actual lookup without impacting outsiders like the Inspector.

* Implement nativePerformanceNow to improve Profiler API results (#27885)

Summary:
When experimenting with React Profiler API (https://reactjs.org/docs/profiler.html), I noticed that durations are integers without a debugger, but they are doubles with higher precision when debugger is attached. After digging into React Profiler code, I found out that it's using `performance.now()` to accumulate execution times of individual units of work. Since this method does not exist in React Native, it falls back to Javascript `Date`, leading to imprecise results.

This PR introduces `global.nativePerformanceNow` function which returns precise native time, and a very basic `performance` polyfill with `now` function.

This will greatly improve React Profiler API results, which is essential for profiling and benchmark tools.

* Save/restore IP when leaving the interpreter

Summary:
This diff implements the instruction pointer save/restore trick Tzvetan came up with; allowing us to observe and modify the IP from outside the interpreter loop with negligible overhead.

From Tzvetan's internal post on the subject:

> [Today] the interpreter IP is just a local variable in the interpreter function, so there is no way to get to its value from outside the function. It lives in a register and we don't want to make it a Runtime field since the overhead [of accessing it via memory in the interpeter loop] would kill us.

> However, if you really think about it, it only lives in a register while the interpreter function is running. For the rest of the time, it is spilled by the C++ compiler onto the stack.
So, precisely when we need it, it is actually stored in memory. The only problem is, we don't know where! Admittedly, that is an annoying problem, but it feels like it should be solvable.

> What if, instead of relying on the compiler to spill the IP register, we manually spill it ourselves, to a known location? It works. Example: https://godbolt.org/z/ftSDnp

This diff implements this approach across the whole interpreter loop: whenever we call out of the loop we capture/publish the IP and restore it again immediately after the external call returns. This means we can now see the IP outside the interpret loop and even change it. This is effectively "for free" as the compiler now skips spilling/restoring the IP behind the scenes.

The immediate benefit of this is knowing the current IP allows us to have more accurate stack-traces during execution. In future this may enabled tricks like changing the IP before returning to th…

* Update default Podfile to not depend on a path (#28572)

Summary:
Recently, a default Podfile has been modified to not contain all the React Native pods, but use a helper method `use_react_native!`.

While this is great, it assumes a hardcoded path of `../node_modules/react-native` to be always the correct location of the React Native.

https://github.com/facebook/react-native/blob/d4d8887b5018782eeb3f26efa85125e6bbff73e4/scripts/autolink-ios.rb#L7-L9

Unfortunately, due to the way Ruby works, this completely hides the path away from the users.

Before, they could have seen the wrong path explicitly in a Podfile and knew to update it to resolve path-related issues.

With the current version in `master`, I can see a lot of issues where developers wonder how to resolve the path issues and how to pass the path itself.

https://github.com/facebook/react-native/blob/4118d798265341061105f3a53550db83c66a71cb/template/ios/Podfile#L5-L10

This PR uses React Native CLI configuration (that is already used to link 3rd party dependencies) to explicitly define the correct path to the React Native.

As a result, we don't have to change the paths here whether we're running monorepo or not.

This change removes the `ColorAndroid` API.   It was added more as a validation tool than as something useful to a developer.   When making the original [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) we felt it was valuable and useful to have working platform specific methods for the two platforms in core to test that the pattern worked in app code (PlatformColorExample.js in RNTester) and that the Flow validation worked, etc.    Practically `PlatformColor()` is more useful to a developer on Android than `ColorAndroid()`.    Now that the construct has served its purpose, this PR removes the `ColorAndroid` function and its related tests and other collateral.

* Retryable ViewCommand exceptions shouldn't crash

Summary:
Early ViewCommand Dispatch will solve this category of crashes by going through an entirely different codepath. For users not in that experiment, it might be good to have a mitigation that prevents non-critical issues from crashing (like "blur" failing).

Currently, "blur" failures cause lots of screens to crash. There's no useful signal and those crashes aren't super actionable, so seems better to swallow.

If/when early viewcommand dispatch ships as the default/only mode, we can remove this try/catch entirely.

The only concern I have with landing this is the perf implications of putting a try/catch inside this loop.

* Yoga Podspec: Export YGNode and YGStyle headers (#997)

Summary:
This pull request adds `YGNode.h` and `YGStyle.h` to the headers exported by Yoga's podspec. They are required by the new Fabric architecture of React Native.

The modulemap and its umbrella header automatically generated by Cocoapods adds all exported headers to the `modulemap`. Having YGNode and YGStyle exported through here has problems, because they are only available in environments that have C++ available, and will produce errors otherwise.

This pull request fences off the contents of those headers in an `#ifdef __cplusplus` block, so they will not cause errors when imported into environments where C++ isn't available.

I had considered adding a custom modulemap to the podspec as part of this pull request, but this way seems the least "invasive", and this way you are able to add and remove exported headers in the podspec without needing to worry about updating the umbrella header at the same time.

* Control concurrent calls into TMMDelegate from TMM

Summary:
In D20659799, I improved `TurboModuleManager.getModule(moduleName)` thread-safety by ensuring that if two threads race to require the same NativeModule, only one thread creates the NativeModule, while the other one waits until it's created.

## The problem:
What I failed to realize was that when two threads race to require two different NativeModules, we can get concurrent calls into `TurboModuleManagerDelegate.getModule(moduleName)`, and `TurboModuleManagerDelegate.getLegacyCxxModule(moduleName)`, which don't have any thread-safe guarantees.

## The fix
`TurboModuleManagerDelegate` is supposed to be an input to the TurboModule system. So, rather than expecting that all TurboModuleManagerDelegates are thread-safe, which might be a reasonable ask (see T65532092), this diff has `TurboModuleManager` acquire the delegate's lock before calling into it. This ensures that we don't get concurrent access into the delegate, which could be reading from, or writing to, some data structure in these method calls. (This was the case with `ReactPackageTurboModuleManagerDelegate`, which is what Fb4a and Workplace use under the hood).

* Switch over to JavaTurboModule::InitParams

Summary:
## Problem
Every time we want to add, remove, or change the data passed to JavaTurboModule's constructor, we have to modify the C++ TurboModule codegen. (The same is true of `ObjCTurboModule`).

**Why was this necessary?**
- `JavaTurboModule` is effectively an abstract class whose constructor is always invoked by code-generated C++ classes. These C++ code-generated class constructors accept an argument list, and manually foward each and every item in that list to `JavaTurboModule::JavaTurboModule`.

## The fix
In this diff, I introduce a struct `JavaTurboModule::InitParams`, to represent a bag of arguments:
```
class JSI_EXPORT JavaTurboModule : public TurboModule {
 public:
  struct InitParams {
    std::string moduleName;
    jni::alias_ref<JTurboModule> instance;
    std::shared_ptr<CallInvoker> jsInvoker;
    std::shared_ptr<CallInvoker> nativeInvoker;
  };
```

All `JavaTurboModules` will be created with an instance of this `InitParams` struct, instead of a list of arguments.  Our code-generated C++ `jsi::HostObject` sublcasses will simply accept `InitParams` in their constructor, and forward it to `JavaTurboModule`'s constructor. This way, the codegen remains oblivious to what arguments JavaTurboModule requires.

## Okay, but why do we need this change now?
In the future, I plan to modify the constructor for `JavaTurboModule` to accept a performance logger, and a `RuntimeExecutor`. Similar modifications are planned for ObjC. For this reason, to avoid these four codemods, and any potential other codemods that occur because we're making modifications to `JavaTurboModule` or `ObjCTurboModule`, I'm launching this codemod, and the codemods in this stack.

## Misc Fix
- Previously, we were generating the TurboModule name from the Spec filename. This is incorrect because that name represents the spec name. Now, the name will be forwarded from TurboModuleManager in the `JavaTurboModule::InitParams` struct.

## Alternative implementations
I initially considered using `ContextContainer`, but decided against it because:
1. There are no type-safety guarantees.
2. I think it's a bit overkill for this scenario. We just need an opaque bag of data, and for our purposes a simple struct does the job fine.

* RN: Shrinkwrap Text Layout (Android)

Summary:
When text is in a constrained parent view using `maxWidth`, long text may wrap. When the text wraps, the final width is dependent on the word breaking strategy and text content. This means that the text width is not necessarily `maxWidth`.

However, the current way that we compute text layout does not shrinkwrap the text width as much as possible. This leads to visual gaps to the end-side of wrapped text.

This changes the text layout slightly so that we use the length of the longest line.

This bug only exists on Android. After this change, Android behaves like iOS.

Summary:
Add more options to the LayoutAnimation example so it's easier to test more features of LayoutAnimations.

1) Add an option to animate reordering of views
2) Make animations slower, so it's easier to see what's going on and easier to trigger race conditions

* Fix jsi cmake include dirs (#207)

Summary:
I'm trying to use JSI for a React Native custom module. I saw these existing examples where the JSI API is used in the context of a CMakeLists.txt:
https://github.com/terrysahaidak/host-object-test/blob/master/libs/android-jsi/test-jsi/src/main/cpp/CMakeLists.txt
https://github.com/ericlewis/react-native-hostobject-demo/pull/4/files#diff-834320be1b4e4016bac27c05dcd17fb9
In both cases, they manually grab the include directories and jsi.cpp from node_modules/react-native, but I also saw that node_modules/react-native/ReactCommon/jsi/jsi already has a CMakeLists.txt that appears to be intended to provide a jsi static lib, so I tried to pull this into my own CMakeLists.txt like this:
```
add_subdirectory(${RN_DIR}/ReactCommon/jsi/jsi ${CMAKE_CURRENT_BINARY_DIR}/jsi)
...
target_link_libraries(MyLib jsi)
```
Unfortunately when doing this, the consuming project still doesn't see the correct include directories. The change I'm proposing here is to use `target_include_directories` and declare that `..` is a public (to consumers) include directory for the library named `jsi`. With this change, you can do what I showed above to consume the jsi lib by just pulling in the CMakeLists.txt file into your own CMakeLists.txt file.

* Part 1: Update ObjC++ codegen classes to use ObjCTurboModule::InitParams

Summary:
## Summary
Please check out D21035208.

## Changes
- `ObjCTurboModule::ObjCTurboModule` changed to accept a bag of arguments `const ObjCTurboModule::InitParams` instead of an argument list.
- TurboModule iOS codegen scripts updated to generated `ObjCTurboModule` subclasses that accept a `const ObjCTurboModule::InitParams` object in their constructor, and forward it to `ObjCTurboModule::ObjCTurboModule`.
- All manually checked in code-generated ObjC++ classes (i.e: RCTNativeSampleTurboModule, RCTTestModule, FBReactNativeSpec) are updated.

## Rationale
This way, the code-gen can remain constant while we add, remove, or modify the arguments passed to ObjCTurboModule.

## Commands run
```
function update-codegen() {
  pushd ~/fbsource && js1 build oss-native-modules-specs -p ios && js1 build oss-native-modules-specs -p android && popd;

* Fabric: Fixed incorrect early-return in `UIView+ComponentViewProtocol::updateLayoutMetrics`

Summary:
Before the change, an incorrect (NaN or Inf) values in LayoutMetrics might force an early return in the `updateLayoutMetrics:oldMetrics:` method implementation. This was not correct because the rest of the method also didn't run in this case, so it might force some value to stale.
E.g., imagine we have an instruction that contains NaN size and `display: none`. Previously, the function might just return right before applying sizes and progress the stored "already applied" value of LayoutMetrics which will cause the view being visible even if it should not.

Summary:
This PR fixes incorrect drawing of the View borders on Android, after changing the border-radius back to 0 *(and when no background-color is defined)*.

This happens because the `drawRoundedBackgroundWithBorders` function in ReactViewBackgroundDrawable changes the style on the Paint object to `STROKE`.

Now it only fires only when the base `props` object is null, which is practically all production cases we have (and care about).

From the other side, the old behavior that may return the same props objects previously several times created bugs and practically unexpected results and practically disallowed to clone props objects easily.

* Upgrade to Jest 25

Summary:
This diff upgrades Jest to the latest version which fixes a bunch of issues with snapshots (therefore allowing me to enable the Pressable-test again). Note that this also affects Metro and various other tooling as they all depend on packages like `jest-worker`, `jest-haste-map` etc.

Breaking changes: https://github.com/facebook/jest/blob/master/CHANGELOG.md

This diff increases node_modules by 3 MiB, primarily because it causes more duplicates of `source-map` (0.8 MiB for each copy) and packages like `chalk` 3.x (vs 2.x). The base install was 15 MiB bigger and I reduced it to this size by playing around with various manual yarn.lock optimizations. However, D21085929 reduces node_modules by 11 MiB and the Babel upgrade reduced node_modules by 13 MiB. I will subsequently work on reducing the size through other packages as well and I'm working with the Jest folks to get rid of superfluous TypeScript stuff for Jest 26.

Other changes in this diff:
* Fixed Pressable-test
* Blackhole node-notifier: It's large and we don't need it, and also the license may be problematic, see: https://github.com/facebook/jest/pull/8918
* Updated jest-junit (not a Jest package) but blackholed it internally because it is only used for open source CI.
* Updated some API calls we use from Jest to account for breaking changes
* Made two absolutely egrigious changes to existing product code tests to make them still pass as our match of async/await, fake timers and then/promise using `setImmediate` is tripping up `regenerator` with `Generator is already run` errors in Jest 25. These tests should probably be rewritten.

* Fabric: More strict policies to dirty Yoga nodes in YogaLayoutableShadowNode

Summary:
Yoga uses a dirty flag to re-layout nodes. In normal, single-threaded approach the policy for dirtying is simple: if a node was changed, we need to dirty it. In the Concurrent Yoga approach, those rules are not so simple, and it seems we haven't formalized those rules yet.

Investigating some layout issues that we have in Fabric, I tend to believe that we don't dirty as much we should. Hense this change adds mode dirtying.

* Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors (#28703)

Summary:
Per discussion in https://github.com/react-native-community/releases/issues/186 the iOS `PlatformColor()` function is documented to use the semantic color names provided by the system.   The referenced HIG documentation itself links to the `UIColor` documentation for semantic colors names.   However, these names differ depending on if you are viewing the new Swift API docs or the Objective C docs.   The current Objective C implementation in react-native assumes Objective C UIColor selector names that are suffixed 'Color'.   But in Swift, Apple provides a Swift Extension on UIColor that makes aliases without the the 'Color' suffix and then makes the original selectors invalid presumably via `NS_UNAVAILABLE_SWIFT`.

Since both selector names are valid depending on if you are using Objective C or Swift, let's make both forms be legal for `PlatformColor()`.   In `RCTConvert.m` there is a dictionary of legal selector names.   The code already supports the ability to have names be aliases of other selectors via a RCTSelector metadata key.   The change adds code to the initialization of the map: it iterates over the keys in the map, which are all ObjC style UIColor selectors, and creates aliases by duplicating the entries, creating key names by stripping off the ObjC "Color" suffix, adds the RCTSelector key referring to the original and then appends these new Swift aliases to the map.

## Changelog

[iOS] [Changed] - Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors
Pull Request resolved: https://github.com/facebook/react-native/pull/28703

Test Plan:
The PlatformColorExample.js is updated to use the new, shorter Swift selector names.   There are still other examples in the same file and in unit tests that exercise the ObjC selector names.

Summary:
Adds `RootTag` as a valid type for arguments and return types in TurboModules (on both Android and iOS).

This will enable us to change `RootTag` into an opaque type. There are two compelling reasons to do this:

- JavaScript will no longer be able to safely depend on `RootTag` being a number (which means we can change this in the future).
- Call sites using `unstable_RootTagContext` will can get a `RootTag`, but call sites using the legacy `context.rootTag` will not. This means the opaque type will give us a strategy for migrating away from legacy context and eventually making `unstable_RootTagContext` the only way to access `RootTag`.

* Overhaul RCTTurboModule creation and initialization

Summary:
## Problems:
In my investigation of T65656635, I realized that the TurboModule system has a number of problems:
- In TurboModules, we use 1 lock to create n TurboModules. We should change this setup to n locks for n TurboModules. This way, two threads creating two different NativeModules don't compete for the same lock. Also, this is how it's done in Android (TurboModules & NativeModules), and iOS (NativeModules).
- In TurboModules, we don't calculate "requires main queue setup" faithfully. In the legacy system, if a NativeModule has a custom `init` method or a custom `constantsToExport` method, it "requires main queue setup" with a warning.
- In TurboModules, we don't create the NativeModule on the main queue, if "requires main queue setup" is true. Instead, the NativeModule is always created on the thread that requires it.
- In TurboModules, we don't perform any concurrency control around `id<RCTTurboModule>` setup. We should.

## What this diff does
In this diff, I fixed all the aforementioned issues by re-implementing `provideRCTTurboModule:`.

**Algorithm Notes:**
- **Gist:** When `n` threads race to create NativeModule `x`, only the first thread creates and sets up `x`. All others are told to wait. Once the creator thread finishes its job, it notifies all other waiting threads, which then wake up and return the newly created NativeModule. This algorithm was initially implemented in NativeModules for Android inside (ModuleHolder.java). I modified and implemented it for TurboModules for Android, and now this diff implements it for TurboModules for iOS.
- The TurboModule cache is replace with a TurboModuleHolder map. A TurboModuleHolder manages the creation lifecycle of a TurboModule, and holds a condition variable and mutex for doing concurrency control around it. When the bridge invalidates, in TurboModuleManager, we set the `invalidating` flag to true, which prevents the insertion of new entries into the TurboModuleHolder map.
- I added a `std::mutex` to serialize calls into the TurboModuleManagerDelegate, so we don't get races if the delegate isn't thread-safe.

* Fix folly::dynamic crash when attaching a debugger to Hermes

Summary:
folly_futures was compiled with and exported -DFOLLY_MOBILE=1, while
folly_json did not. This flag disables fancy F14 data structures for
folly::dynamic in favor of a simple std::unordered_map.

This caused inlined/templated code from modules depending on
folly_futures to disagree with the implementations in folly_json,
leading to a crash.

The only such libraries were libhermes-inspector and (transitively)
libhermes-executor-debug, and these only use folly::dynamic for CDP
serialization, which is why the problem was not more apparent.

* Update default Podfile to not depend on a path (#28572)

Summary:
Recently, a default Podfile has been modified to not contain all the React Native pods, but use a helper method `use_react_native!`.

While this is great, it assumes a hardcoded path of `../node_modules/react-native` to be always the correct location of the React Native.

https://github.com/facebook/react-native/blob/d4d8887b5018782eeb3f26efa85125e6bbff73e4/scripts/autolink-ios.rb#L7-L9

Unfortunately, due to the way Ruby works, this completely hides the path away from the users.

Before, they could have seen the wrong path explicitly in a Podfile and knew to update it to resolve path-related issues.

With the current version in `master`, I can see a lot of issues where developers wonder how to resolve the path issues and how to pass the path itself.

https://github.com/facebook/react-native/blob/4118d798265341061105f3a53550db83c66a71cb/template/ios/Podfile#L5-L10

This PR uses React Native CLI configuration (that is already used to link 3rd party dependencies) to explicitly define the correct path to the React Native.

As a result, we don't have to change the paths here whether we're running monorepo or not.

This change removes the `ColorAndroid` API.   It was added more as a validation tool than as something useful to a developer.   When making the original [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) we felt it was valuable and useful to have working platform specific methods for the two platforms in core to test that the pattern worked in app code (PlatformColorExample.js in RNTester) and that the Flow validation worked, etc.    Practically `PlatformColor()` is more useful to a developer on Android than `ColorAndroid()`.    Now that the construct has served its purpose, this PR removes the `ColorAndroid` function and its related tests and other collateral.

* Animated: Early detection of division by zero in AnimatedDivision

Summary:
We currently see a lot of errors happens because of division by zero in `AnimatedDivision` module. We already have a check for that in the module but it happens during the animation tick where the context of execution is already lost and it's hard to find why exactly it happens.
Adding an additional check to the constructor should trigger an error right inside render function which should make the error actionable.

* Retryable ViewCommand exceptions shouldn't crash

Summary:
Early ViewCommand Dispatch will solve this category of crashes by going through an entirely different codepath. For users not in that experiment, it might be good to have a mitigation that prevents non-critical issues from crashing (like "blur" failing).

Currently, "blur" failures cause lots of screens to crash. There's no useful signal and those crashes aren't super actionable, so seems better to swallow.

If/when early viewcommand dispatch ships as the default/only mode, we can remove this try/catch entirely.

The only concern I have with landing this is the perf implications of putting a try/catch inside this loop.

* Yoga Podspec: Export YGNode and YGStyle headers (#997)

Summary:
This pull request adds `YGNode.h` and `YGStyle.h` to the headers exported by Yoga's podspec. They are required by the new Fabric architecture of React Native.

The modulemap and its umbrella header automatically generated by Cocoapods adds all exported headers to the `modulemap`. Having YGNode and YGStyle exported through here has problems, because they are only available in environments that have C++ available, and will produce errors otherwise.

This pull request fences off the contents of those headers in an `#ifdef __cplusplus` block, so they will not cause errors when imported into environments where C++ isn't available.

I had considered adding a custom modulemap to the podspec as part of this pull request, but this way seems the least "invasive", and this way you are able to add and remove exported headers in the podspec without needing to worry about updating the umbrella header at the same time.

* Control concurrent calls into TMMDelegate from TMM

Summary:
In D20659799, I improved `TurboModuleManager.getModule(moduleName)` thread-safety by ensuring that if two threads race to require the same NativeModule, only one thread creates the NativeModule, while the other one waits until it's created.

## The problem:
What I failed to realize was that when two threads race to require two different NativeModules, we can get concurrent calls into `TurboModuleManagerDelegate.getModule(moduleName)`, and `TurboModuleManagerDelegate.getLegacyCxxModule(moduleName)`, which don't have any thread-safe guarantees.

## The fix
`TurboModuleManagerDelegate` is supposed to be an input to the TurboModule system. So, rather than expecting that all TurboModuleManagerDelegates are thread-safe, which might be a reasonable ask (see T65532092), this diff has `TurboModuleManager` acquire the delegate's lock before calling into it. This ensures that we don't get concurrent access into the delegate, which could be reading from, or writing to, some data structure in these method calls. (This was the case with `ReactPackageTurboModuleManagerDelegate`, which is what Fb4a and Workplace use under the hood).

* Switch over to JavaTurboModule::InitParams

Summary:
## Problem
Every time we want to add, remove, or change the data passed to JavaTurboModule's constructor, we have to modify the C++ TurboModule codegen. (The same is true of `ObjCTurboModule`).

**Why was this necessary?**
- `JavaTurboModule` is effectively an abstract class whose constructor is always invoked by code-generated C++ classes. These C++ code-generated class constructors accept an argument list, and manually foward each and every item in that list to `JavaTurboModule::JavaTurboModule`.

## The fix
In this diff, I introduce a struct `JavaTurboModule::InitParams`, to represent a bag of arguments:
```
class JSI_EXPORT JavaTurboModule : public TurboModule {
 public:
  struct InitParams {
    std::string moduleName;
    jni::alias_ref<JTurboModule> instance;
    std::shared_ptr<CallInvoker> jsInvoker;
    std::shared_ptr<CallInvoker> nativeInvoker;
  };
```

All `JavaTurboModules` will be created with an instance of this `InitParams` struct, instead of a list of arguments.  Our code-generated C++ `jsi::HostObject` sublcasses will simply accept `InitParams` in their constructor, and forward it to `JavaTurboModule`'s constructor. This way, the codegen remains oblivious to what arguments JavaTurboModule requires.

## Okay, but why do we need this change now?
In the future, I plan to modify the constructor for `JavaTurboModule` to accept a performance logger, and a `RuntimeExecutor`. Similar modifications are planned for ObjC. For this reason, to avoid these four codemods, and any potential other codemods that occur because we're making modifications to `JavaTurboModule` or `ObjCTurboModule`, I'm launching this codemod, and the codemods in this stack.

## Misc Fix
- Previously, we were generating the TurboModule name from the Spec filename. This is incorrect because that name represents the spec name. Now, the name will be forwarded from TurboModuleManager in the `JavaTurboModule::InitParams` struct.

## Alternative implementations
I initially considered using `ContextContainer`, but decided against it because:
1. There are no type-safety guarantees.
2. I think it's a bit overkill for this scenario. We just need an opaque bag of data, and for our purposes a simple struct does the job fine.

* RN: Shrinkwrap Text Layout (Android)

Summary:
When text is in a constrained parent view using `maxWidth`, long text may wrap. When the text wraps, the final width is dependent on the word breaking strategy and text content. This means that the text width is not necessarily `maxWidth`.

However, the current way that we compute text layout does not shrinkwrap the text width as much as possible. This leads to visual gaps to the end-side of wrapped text.

This changes the text layout slightly so that we use the length of the longest line.

This bug only exists on Android. After this change, Android behaves like iOS.

* Fix jsi cmake include dirs (#207)

Summary:
I'm trying to use JSI for a React Native custom module. I saw these existing examples where the JSI API is used in the context of a CMakeLists.txt:
https://github.com/terrysahaidak/host-object-test/blob/master/libs/android-jsi/test-jsi/src/main/cpp/CMakeLists.txt
https://github.com/ericlewis/react-native-hostobject-demo/pull/4/files#diff-834320be1b4e4016bac27c05dcd17fb9
In both cases, they manually grab the include directories and jsi.cpp from node_modules/react-native, but I also saw that node_modules/react-native/ReactCommon/jsi/jsi already has a CMakeLists.txt that appears to be intended to provide a jsi static lib, so I tried to pull this into my own CMakeLists.txt like this:
```
add_subdirectory(${RN_DIR}/ReactCommon/jsi/jsi ${CMAKE_CURRENT_BINARY_DIR}/jsi)
...
target_link_libraries(MyLib jsi)
```
Unfortunately when doing this, the consuming project still doesn't see the correct include directories. The change I'm proposing here is to use `target_include_directories` and declare that `..` is a public (to consumers) include directory for the library named `jsi`. With this change, you can do what I showed above to consume the jsi lib by just pulling in the CMakeLists.txt file into your own CMakeLists.txt file.

* Fabric: Fixed incorrect early-return in `UIView+ComponentViewProtocol::updateLayoutMetrics`

Summary:
Before the change, an incorrect (NaN or Inf) values in LayoutMetrics might force an early return in the `updateLayoutMetrics:oldMetrics:` method implementation. This was not correct because the rest of the method also didn't run in this case, so it might force some value to stale.
E.g., imagine we have an instruction that contains NaN size and `display: none`. Previously, the function might just return right before applying sizes and progress the stored "already applied" value of LayoutMetrics which will cause the view being visible even if it should not.

Summary:
This PR fixes incorrect drawing of the View borders on Android, after changing the border-radius back to 0 *(and when no background-color is defined)*.

This happens because the `drawRoundedBackgroundWithBorders` function in ReactViewBackgroundDrawable changes the style on the Paint object to `STROKE`.

Summary:
The diff changes how the `empty raw props` optimization works in `ComponentDescriptor::cloneProps()`. Now it only fires only when the base `props` object is null, which is practically all production cases we have (and care about). (I tried, in a normal run there were no cases where the empty raw props were passed with non-null props.) From the other side, the old behavior that may return the same props objects previously several times created bugs and practically unexpected results and practically disallowed to clone props objects easily.

* Upgrade to Jest 25

Summary:
This diff upgrades Jest to the latest version which fixes a bunch of issues with snapshots (therefore allowing me to enable the Pressable-test again). Note that this also affects Metro and various other tooling as they all depend on packages like `jest-worker`, `jest-haste-map` etc.

Breaking changes: https://github.com/facebook/jest/blob/master/CHANGELOG.md

This diff increases node_modules by 3 MiB, primarily because it causes more duplicates of `source-map` (0.8 MiB for each copy) and packages like `chalk` 3.x (vs 2.x). The base install was 15 MiB bigger and I reduced it to this size by playing around with various manual yarn.lock optimizations. However, D21085929 reduces node_modules by 11 MiB and the Babel upgrade reduced node_modules by 13 MiB. I will subsequently work on reducing the size through other packages as well and I'm working with the Jest folks to get rid of superfluous TypeScript stuff for Jest 26.

Other changes in this diff:
* Fixed Pressable-test
* Blackhole node-notifier: It's large and we don't need it, and also the license may be problematic, see: https://github.com/facebook/jest/pull/8918
* Updated jest-junit (not a Jest package) but blackholed it internally because it is only used for open source CI.
* Updated some API calls we use from Jest to account for breaking changes
* Made two absolutely egrigious changes to existing product code tests to make them still pass as our match of async/await, fake timers and then/promise using `setImmediate` is tripping up `regenerator` with `Generator is already run` errors in Jest 25. These tests should probably be rewritten.
* Locked everything to the same `resolve` version that we were already using, otherwise it was somehow pulling in 1.16 even though nothing internally uses it.

Summary:
Yoga uses a dirty flag to re-layout nodes. In normal, single-threaded approach the policy for dirtying is simple: if a node was changed, we need to dirty it. In the Concurrent Yoga approach, those rules are not so simple, and it seems we haven't formalized those rules yet.

* Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors (#28703)

Summary:
Per discussion in https://github.com/react-native-community/releases/issues/186 the iOS `PlatformColor()` function is documented to use the semantic color names provided by the system.   The referenced HIG documentation itself links to the `UIColor` documentation for semantic colors names.   However, these names differ depending on if you are viewing the new Swift API docs or the Objective C docs.   The current Objective C implementation in react-native assumes Objective C UIColor selector names that are suffixed 'Color'.   But in Swift, Apple provides a Swift Extension on UIColor that makes aliases without the the 'Color' suffix and then makes the original selectors invalid presumably via `NS_UNAVAILABLE_SWIFT`.

Since both selector names are valid depending on if you are using Objective C or Swift, let's make both forms be legal for `PlatformColor()`.   In `RCTConvert.m` there is a dictionary of legal selector names.   The code already supports the ability to have names be aliases of other selectors via a RCTSelector metadata key.   The change adds code to the initialization of the map: it iterates over the keys in the map, which are all ObjC style UIColor selectors, and creates aliases by duplicating the entries, creating key names by stripping off the ObjC "Color" suffix, adds the RCTSelector key referring to the original and then appends these new Swift aliases to the map.

## Changelog

[iOS] [Changed] - Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors
Pull Request resolved: https://github.com/facebook/react-native/pull/28703

Test Plan:
The PlatformColorExample.js is updated to use the new, shorter Swift selector names.   There are still other examples in the same file and in unit tests that exercise the ObjC selector names.

* RN: Add `RootTag` Type to TurboModule

Summary:
Adds `RootTag` as a valid type for arguments and return types in TurboModules (on both Android and iOS).

This will enable us to change `RootTag` into an opaque type. There are two compelling reasons to do this:

- JavaScript will no longer be able to safely depend on `RootTag` being a number (which means we can change this in the future).
- Call sites using `unstable_RootTagContext` will can get a `RootTag`, but call sites using the legacy `context.rootTag` will not. This means the opaque type will give us a strategy for migrating away from legacy context and eventually making `unstable_RootTagContext` the only way to access `RootTag`.

* Overhaul RCTTurboModule creation and initialization

Summary:
## Problems:
In my investigation of T65656635, I realized that the TurboModule system has a number of problems:
- In TurboModules, we use 1 lock to create n TurboModules. We should change this setup to n locks for n TurboModules. This way, two threads creating two different NativeModules don't compete for the same lock. Also, this is how it's done in Android (TurboModules & NativeModules), and iOS (NativeModules).
- In TurboModules, we don't calculate "requires main queue setup" faithfully. In the legacy system, if a NativeModule has a custom `init` method or a custom `constantsToExport` method, it "requires main queue setup" with a warning.
- In TurboModules, we don't create the NativeModule on the main queue, if "requires main queue setup" is true. Instead, the NativeModule is always created on the thread that requires it.
- In TurboModules, we don't perform any concurrency control around `id<RCTTurboModule>` setup. We should.

## What this diff does
In this diff, I fixed all the aforementioned issues by re-implementing `provideRCTTurboModule:`.

**Algorithm Notes:**
- **Gist:** When `n` threads race to create NativeModule `x`, only the first thread creates and sets up `x`. All others are told to wait. Once the creator thread finishes its job, it notifies all other waiting threads, which then wake up and return the newly created NativeModule. This algorithm was initially implemented in NativeModules for Android inside (ModuleHolder.java). I modified and implemented it for TurboModules for Android, and now this diff implements it for TurboModules for iOS.
- The TurboModule cache is replace with a TurboModuleHolder map. A TurboModuleHolder manages the creation lifecycle of a TurboModule, and holds a condition variable and mutex for doing concurrency control around it. When the bridge invalidates, in TurboModuleManager, we set the `invalidating` flag to true, which prevents the insertion of new entries into the TurboModuleHolder map.
- I added a `std::mutex` to serialize calls into the TurboModuleManagerDelegate, so we don't get races if the delegate isn't thread-safe.

* Fix folly::dynamic crash when attaching a debugger to Hermes

Summary:
folly_futures was compiled with and exported -DFOLLY_MOBILE=1, while
folly_json did not. This flag disables fancy F14 data structures for
folly::dynamic in favor of a simple std::unordered_map.

This caused inlined/templated code from modules depending on
folly_futures to disagree with the implementations in folly_json,
leading to a crash.

The only such libraries were libhermes-inspector and (transitively)
libhermes-executor-debug, and these only use folly::dynamic for CDP
serialization, which is why the problem was not more apparent.

* Update default Podfile to not depend on a path (#28572)

Summary:
Recently, a default Podfile has been modified to not contain all the React Native pods, but use a helper method `use_react_native!`.

While this is great, it assumes a hardcoded path of `../node_modules/react-native` to be always the correct location of the React Native.

https://github.com/facebook/react-native/blob/d4d8887b5018782eeb3f26efa85125e6bbff73e4/scripts/autolink-ios.rb#L7-L9

Unfortunately, due to the way Ruby works, this completely hides the path away from the users.

Before, they could have seen the wrong path explicitly in a Podfile and knew to update it to resolve path-related issues.

With the current version in `master`, I can see a lot of issues where developers wonder how to resolve the path issues and how to pass the path itself.

https://github.com/facebook/react-native/blob/4118d798265341061105f3a53550db83c66a71cb/template/ios/Podfile#L5-L10

This PR uses React Native CLI configuration (that is already used to link 3rd party dependencies) to explicitly define the correct path to the React Native.

As a result, we don't have to change the paths here whether we're running monorepo or not.

Summary:
This change removes the `ColorAndroid` API.   It was added more as a validation tool than as something useful to a developer.   When making the original [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) we felt it was valuable and useful to have working platform specific methods for the two platforms in core to test that the pattern worked in app code (PlatformColorExample.js in RNTester) and that the Flow validation worked, etc.    Practically `PlatformColor()` is more useful to a developer on Android than `ColorAndroid()`.    Now that the construct has served its purpose, this PR removes the `ColorAndroid` function and its related tests and other collateral.

* Retryable ViewCommand exceptions shouldn't crash

Summary:
Early ViewCommand Dispatch will solve this category of crashes by going through an entirely different codepath. For users not in that experiment, it might be good to have a mitigation that prevents non-critical issues from crashing (like "blur" failing).

Currently, "blur" failures cause lots of screens to crash. There's no useful signal and those crashes aren't super actionable, so seems better to swallow.

If/when early viewcommand dispatch ships as the default/only mode, we can remove this try/catch entirely.

The only concern I have with landing this is the perf implications of putting a try/catch inside this loop.

* Yoga Podspec: Export YGNode and YGStyle headers (#997)

Summary:
This pull request adds `YGNode.h` and `YGStyle.h` to the headers exported by Yoga's podspec. They are required by the new Fabric architecture of React Native.

The modulemap and its umbrella header automatically generated by Cocoapods adds all exported headers to the `modulemap`. Having YGNode and YGStyle exported through here has problems, because they are only available in environments that have C++ available, and will produce errors otherwise.

This pull request fences off the contents of those headers in an `#ifdef __cplusplus` block, so they will not cause errors when imported into environments where C++ isn't available.

I had considered adding a custom modulemap to the podspec as part of this pull request, but this way seems the least "invasive", and this way you are able to add and remove exported headers in the podspec without needing to worry about updating the umbrella header at the same time.

* Control concurrent calls into TMMDelegate from TMM

Summary:
In D20659799, I improved `TurboModuleManager.getModule(moduleName)` thread-safety by ensuring that if two threads race to require the same NativeModule, only one thread creates the NativeModule, while the other one waits until it's created.

## The problem:
What I failed to realize was that when two threads race to require two different NativeModules, we can get concurrent calls into `TurboModuleManagerDelegate.getModule(moduleName)`, and `TurboModuleManagerDelegate.getLegacyCxxModule(moduleName)`, which don't have any thread-safe guarantees.

## The fix
`TurboModuleManagerDelegate` is supposed to be an input to the TurboModule system. So, rather than expecting that all TurboModuleManagerDelegates are thread-safe, which might be a reasonable ask (see T65532092), this diff has `TurboModuleManager` acquire the delegate's lock before calling into it. This ensures that we don't get concurrent access into the delegate, which could be reading from, or writing to, some data structure in these method calls. (This was the case with `ReactPackageTurboModuleManagerDelegate`, which is what Fb4a and Workplace use under the hood).

* Changed iOS LaunchScreen from xib to storyboard (#28239)

Summary:
> Starting April 30, 2020, all apps submitted to the App Store must use an Xcode storyboard to provide the app’s launch screen and all iPhone apps must support all iPhone screens.

Updated iOS Launch screen as per [App Store policy change](https://developer.apple.com/news/?id=03042020b).

Community discussion: https://github.com/react-native-community/discussions-and-proposals/issues/209

## Changelog

Changed iOS Launch Screen from a `xib` to `storyboard`. The `LaunchScreen.xib` file has been replaced with `LaunchScreen.storyboard`. Xcode automatically picks up the new Launch Screen no additional change is required.

[iOS] [Deleted] - Deleted LaunchScreen.xib
[iOS] [Added] - Added LaunchScreen.storyboard
Pull Request resolved: https://github.com/facebook/react-native/pull/28239

Test Plan: Build the Xcode project under `template/iOS` and verify that the new launch screen is identical to the previous one.

* Switch over to JavaTurboModule::InitParams

Summary:
## Problem
Every time we want to add, remove, or change the data passed to JavaTurboModule's constructor, we have to modify the C++ TurboModule codegen. (The same is true of `ObjCTurboModule`).

**Why was this necessary?**
- `JavaTurboModule` is effectively an abstract class whose constructor is always invoked by code-generated C++ classes. These C++ code-generated class constructors accept an argument list, and manually foward each and every item in that list to `JavaTurboModule::JavaTurboModule`.

## The fix
In this diff, I introduce a struct `JavaTurboModule::InitParams`, to represent a bag of arguments:
```
class JSI_EXPORT JavaTurboModule : public TurboModule {
 public:
  struct InitParams {
    std::string moduleName;
    jni::alias_ref<JTurboModule> instance;
    std::shared_ptr<CallInvoker> jsInvoker;
    std::shared_ptr<CallInvoker> nativeInvoker;
  };
```

All `JavaTurboModules` will be created with an instance of this `InitParams` struct, instead of a list of arguments.  Our code-generated C++ `jsi::HostObject` sublcasses will simply accept `InitParams` in their constructor, and forward it to `JavaTurboModule`'s constructor. This way, the codegen remains oblivious to what arguments JavaTurboModule requires.

## Okay, but why do we need this change now?
In the future, I plan to modify the constructor for `JavaTurboModule` to accept a performance logger, and a `RuntimeExecutor`. Similar modifications are planned for ObjC. For this reason, to avoid these four codemods, and any potential other codemods that occur because we're making modifications to `JavaTurboModule` or `ObjCTurboModule`, I'm launching this codemod, and the codemods in this stack.

## Misc Fix
- Previously, we were generating the TurboModule name from the Spec filename. This is incorrect because that name represents the spec name. Now, the name will be forwarded from TurboModuleManager in the `JavaTurboModule::InitParams` struct.

## Alternative implementations
I initially considered using `ContextContainer`, but decided against it because:
1. There are no type-safety guarantees.
2. I think it's a bit overkill for this scenario. We just need an opaque bag of data, and for our purposes a simple struct does the job fine.

* RN: Shrinkwrap Text Layout (Android)

Summary:
When text is in a constrained parent view using `maxWidth`, long text may wrap. When the text wraps, the final width is dependent on the word breaking strategy and text content. This means that the text width is not necessarily `maxWidth`.

However, the current way that we compute text layout does not shrinkwrap the text width as much as possible. This leads to visual gaps to the end-side of wrapped text.

This changes the text layout slightly so that we use the length of the longest line.

This bug only exists on Android. After this change, Android behaves like iOS.

* Fix jsi cmake include dirs (#207)

Summary:
I'm trying to use JSI for a React Native custom module. I saw these existing examples where the JSI API is used in the context of a CMakeLists.txt:
https://github.com/terrysahaidak/host-object-test/blob/master/libs/android-jsi/test-jsi/src/main/cpp/CMakeLists.txt
https://github.com/ericlewis/react-native-hostobject-demo/pull/4/files#diff-834320be1b4e4016bac27c05dcd17fb9
In both cases, they manually grab the include directories and jsi.cpp from node_modules/react-native, but I also saw that node_modules/react-native/ReactCommon/jsi/jsi already has a CMakeLists.txt that appears to be intended to provide a jsi static lib, so I tried to pull this into my own CMakeLists.txt like this:
```
add_subdirectory(${RN_DIR}/ReactCommon/jsi/jsi ${CMAKE_CURRENT_BINARY_DIR}/jsi)
...
target_link_libraries(MyLib jsi)
```
Unfortunately when doing this, the consuming project still doesn't see the correct include directories. The change I'm proposing here is to use `target_include_directories` and declare that `..` is a public (to consumers) include directory for the library named `jsi`. With this change, you can do what I showed above to consume the jsi lib by just pulling in the CMakeLists.txt file into your own CMakeLists.txt file.

* Part 1: Update ObjC++ codegen classes to use ObjCTurboModule::InitParams

Summary:
## Summary
Please check out D21035208.

## Changes
- `ObjCTurboModule::ObjCTurboModule` changed to accept a bag of arguments `const ObjCTurboModule::InitParams` instead of an argument list.
- TurboModule iOS codegen scripts updated to generated `ObjCTurboModule` subclasses that accept a `const ObjCTurboModule::InitParams` object in their constructor, and forward it to `ObjCTurboModule::ObjCTurboModule`.
- All manually checked in code-generated ObjC++ classes (i.e: RCTNativeSampleTurboModule, RCTTestModule, FBReactNativeSpec) are updated.

## Rationale
This way, the code-gen can remain constant while we add, remove, or modify the arguments passed to ObjCTurboModule.

Summary:
Before the change, an incorrect (NaN or Inf) values in LayoutMetrics might force an early return in the `updateLayoutMetrics:oldMetrics:` method implementation. This was not correct because the rest of the method also didn't run in this case, so it might force some value to stale.
E.g., imagine we have an instruction that contains NaN size and `display: none`. Previously, the function might just return right before applying sizes and progress the stored "already applied" value of LayoutMetrics which will cause the view being visible even if it should not.

* Fix border-stroke drawing after resetting border-radius (#28356)

Summary:
This PR fixes incorrect drawing of the View borders on Android, after changing the border-radius back to 0 *(and when no background-color is defined)*.

This happens because the `drawRoundedBackgroundWithBorders` function in ReactViewBackgroundDrawable changes the style on the Paint object to `STROKE`. This style is however never reverted back to `FILL`. This change ensures that the Paint style is set to `FILL` for the full execution of the `drawRectangularBackgroundWithBorders` function.

* Fix rounded border drawing when border-radius is smaller than border-width (#28358)

Summary:
This PR fixes the drawing of the border rounded edges when the border-radius is small than the border-width. The current implementation capped the possible border-radius making it impossible to set smaller border-radii when using thicker borders. After inspection it was found that the rounded-rect calculation is incorrect.

Pull Request resolved: https://github.com/facebook/react-native/pull/28358

Test Plan:
**Faulty situation:**

As you can see, when the border-radius becomes very low, the border is stuck at a minimum value. Only after setting the border-radius fully to 0 is it again rendered correctly.

* Fabric: `ComponentDescriptor::cloneProps()` now never returns the base props objects

Summary:
The diff changes how the `empty raw props` optimization works in `ComponentDescriptor::cloneProps()`. Now it only fires only when the base `props` object is null, which is practically all production cases we have (and care about). (I tried, in a normal run there were no cases where the empty raw props were passed with non-null props.) From the other side, the old behavior that may return the same props objects previously several times created bugs and practically unexpected results and practically disallowed to clone props objects easily.

* Upgrade to Jest 25

Summary:
This diff upgrades Jest to the latest version which fixes a bunch of issues with snapshots (therefore allowing me to enable the Pressable-test again). Note that this also affects Metro and various other tooling as they all depend on packages like `jest-worker`, `jest-haste-map` etc.

Breaking changes: https://github.com/facebook/jest/blob/master/CHANGELOG.md

This diff increases node_modules by 3 MiB, primarily because it causes more duplicates of `source-map` (0.8 MiB for each copy) and packages like `chalk` 3.x (vs 2.x). The base install was 15 MiB bigger and I reduced it to this size by playing around with various manual yarn.lock optimizations. However, D21085929 reduces node_modules by 11 MiB and the Babel upgrade reduced node_modules by 13 MiB. I will subsequently work on reducing the size through other packages as well and I'm working with the Jest folks to get rid of superfluous TypeScript stuff for Jest 26.

Other changes in this diff:
* Fixed Pressable-test
* Blackhole node-notifier: It's large and we don't need it, and also the license may be problematic, see: https://github.com/facebook/jest/pull/8918
* Updated jest-junit (not a Jest package) but blackholed it internally because it is only used for open source CI.
* Updated some API calls we use from Jest to account for breaking changes
* Made two absolutely egrigious changes to existing product code tests to make them still pass as our match of async/await, fake timers and then/promise using `setImmediate` is tripping up `regenerator` with `Generator is already run` errors in Jest 25. These tests should probably be rewritten.
* Locked everything to the same `resolve` version that we were already using, otherwise it was somehow pulling in 1.16 even though nothing internally uses it.

* Fabric: More strict policies to dirty Yoga nodes in YogaLayoutableShadowNode

Summary:
Yoga uses a dirty flag to re-layout nodes. In normal, single-threaded approach the policy for dirtying is simple: if a node was changed, we need to dirty it. In the Concurrent Yoga approach, those rules are not so simple, and it seems we haven't formalized those rules yet.

Investigating some layout issues that we have in Fabric, I tend to believe that we don't dirty as much we should. Hense this change adds mode dirtying.

* Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors (#28703)

Summary:
Per discussion in https://github.com/react-native-community/releases/issues/186 the iOS `PlatformColor()` function is documented to use the semantic color names provided by the system.   The referenced HIG documentation itself links to the `UIColor` documentation for semantic colors names.   However, these names differ depending on if you are viewing the new Swift API docs or the Objective C docs.   The current Objective C implementation in react-native assumes Objective C UIColor selector names that are suffixed 'Color'.   But in Swift, Apple provides a Swift Extension on UIColor that makes aliases without the the 'Color' suffix and then makes the original selectors invalid presumably via `NS_UNAVAILABLE_SWIFT`.

Since both selector names are valid depending on if you are using Objective C or Swift, let's make both forms be legal for `PlatformColor()`.   In `RCTConvert.m` there is a dictionary of legal selector names.   The code already supports the ability to have names be aliases of other selectors via a RCTSelector metadata key.   The change adds code to the initialization of the map: it iterates over the keys in the map, which are all ObjC style UIColor selectors, and creates aliases by duplicating the entries, creating key names by stripping off the ObjC "Color" suffix, adds the RCTSelector key referring to the original and then appends these new Swift aliases to the map.

## Changelog

[iOS] [Changed] - Allow iOS PlatformColor strings to be ObjC or Swift UIColor selectors
Pull Request resolved: https://github.com/facebook/react-native/pull/28703

Test Plan:
The PlatformColorExample.js is updated to use the new, shorter Swift selector names.   There are still other examples in the same file and in unit tests that exercise the ObjC selector names.

Summary:
Adds `RootTag` as a valid type for arguments and return types in TurboModules (on both Android and iOS).

This will enable us to change `RootTag` into an opaque type. There are two compelling reasons to do this:

- JavaScript will no longer be able to safely depend on `RootTag` being a number (which means we can change this in the future).
- Call sites using `unstable_RootTagContext` will can get a `RootTag`, but call sites using the legacy `context.rootTag` will not. This means the opaque type will give us a strategy for migrating away from legacy context and eventually making `unstable_RootTagContext` the only way to access `RootTag`.

* Overhaul RCTTurboModule creation and initialization

Summary:
## Problems:
In my investigation of T65656635, I realized that the TurboModule system has a number of problems:
- In TurboModules, we use 1 lock to create n TurboModules. We should change this setup to n locks for n TurboModules. This way, two threads creating two different NativeModules don't compete for the same lock. Also, this is how it's done in Android (TurboModules & NativeModules), and iOS (NativeModules).
- In TurboModules, we don't calculate "requires main queue setup" faithfully. In the legacy system, if a NativeModule has a custom `init` method or a custom `constantsToExport` method, it "requires main queue setup" with a warning.
- In TurboModules, we don't create the NativeModule on the main queue, if "requires main queue setup" is true. Instead, the NativeModule is always created on the thread that requires it.
- In TurboModules, we don't perform any concurrency control around `id<RCTTurboModule>` setup. We should.

## What this diff does
In this diff, I fixed all the aforementioned issues by re-implementing `provideRCTTurboModule:`.

**Algorithm Notes:**
- **Gist:** When `n` threads race to create NativeModule `x`, only the first thread creates and sets up `x`. All others are told to wait. Once the creator thread finishes its job, it notifies all other waiting threads, which then wake up and return the newly created NativeModule. This algorithm was initially implemented in NativeModules for Android inside (ModuleHolder.java). I modified and implemented it for TurboModules for Android, and now this diff implements it for TurboModules for iOS.
- The TurboModule cache is replace with a TurboModuleHolder map. A TurboModuleHolder manages the creation lifecycle of a TurboModule, and holds a condition variable and mutex for doing concurrency control around it. When the bridge invalidates, in TurboModuleManager, we set the `invalidating` flag to true, which prevents the insertion of new entries into the TurboModuleHolder map.
- I added a `std::mutex` to serialize calls into the TurboModuleManagerDelegate, so we don't get races if the delegate isn't thread-safe.

Summary:
folly_futures was compiled with and exported -DFOLLY_MOBILE=1, while
folly_json did not. This flag disables fancy F14 data structures for
folly::dynamic in favor of a simple std::unordered_map.

This caused inlined/templated code from modules depending on
folly_futures to disagree with the implementations in folly_json,
leading to a crash.

The only such libraries were libhermes-inspector and (transitively)
libhermes-executor-debug, and these only use folly::dynamic for CDP
serialization, which is why the problem was not more apparent.
