Sam Mueller d38b95f8b7 (iOS) Support for ExtraBold alias of Heavy (font-weight 800)
Summary:
ExtraBold is a fairly common suffix in font naming. A good example is "Circe-ExtraBold". It's usually synonymous with Heavy or Black at font weight 800, as described here: https://www.webtype.com/info/articles/fonts-weights/

This fixes a regression with ExtraBold fonts introduced in d3007b0 where simply having an extrabold font will cause `weightOfFont` to choose this weight aggressively, resulting in all bold text erroneously interpreted as extrabold/heavy. This fix ensures that extrabold is detected before bold, and correctly attributed to `UIFontWeightHeavy`.

Daniel Friesen 28824f8eb3 Implement a JSTester example for the Dimensions API
Summary:
JSTester is missing a page for the Dimensions API. This also makes it hard to test out some things in the tester app that affect the app's frame when you need to know how they affect the dimensions.

Daniel Friesen 165b38ab7a Remove usage of the ... operator in BackHandler
Summary:
This usage of `...` currently causes BackHandler to silently become non-functional when a `Symbol` polyfill is used.

Why?
- The `[...obj]` operator implicitly calls the object's iterator to fill the array
- react-native's internal `Set` polyfill has a load order issue that breaks it whenever a project uses a `Symbol` polyfill
- This means that when `BackHandler` tries to `[...set]` a `Set` of subscriptions the result is always an empty array instead of an array of subscriptions

Additionally it's worth noting that the current code is also wastefully inefficient as in order to reverse iterate over subscriptions it:
- Clones the `Set` (which fills it by implicitly running the set's iterator)
- Uses `[...set]` to convert the cloned set into an array (which also implicitly runs the iterator on the clone)
- Finally reverses the order of the array

----

This code fixes this problem by replacing the use of multiple Set instance iterators with a simple `.forEach` loop that unshifts directly into the final array.

I've tested this by opening the repo's RNTester app on Android and tvOS ensuring that the back handler works before changes, the application crashes when I introduce an error (to verify my code changes are being applied to the app), the back handler works and after changes.

Fixes #11968

ashoat 833b27483b Fix Flow errors at declaration of most major library components
Summary:
The relevant changes in the PR are to Libraries/StyleSheet/EdgeInsetsPropType.js; the rest are just removals of FlowIgnores.

The definition of the relevant types is [here](https://github.com/facebook/flow/blob/master/lib/react.js#L262-L271).

The long and short of it is that for whatever reason, Flow is unable to realize that `ReactPropsChainableTypeChecker` is a subtype of `ReactPropsCheckType` unless we assert it. Once we explicitly hint this to the typechecker, it realizes that `EdgeInsetsPropType` is indeed a valid React PropType, and stops complaining that it isn't.

Krzysztof Magiera bae9b2b206 Handle touchCancel properly in ScrollResponder
Summary:
Touch cancel events are currently being ignored by the ScrollView component. Currently scrollview responds both to scroll events and touchStart/touchMove/touchEnd events.

The reason why ScrollView listens to touchStart/touchEnd is so that it can update its `state.isTouching` param. This parameter then is used in `scrollResponderHandleScrollShouldSetResponder` to make the decision if scrollview should set the responder or not. So if `isTouching` is true (we've received touchStart) then ScrollView want to became a JS responder. This in turn is important for the case where we receive scroll events that does not necessarily need to trigger responder change, e.g. we don't want Scrollview to become JS responder if scroll events have been triggered by `scrollTo` in which case setting responder would put the whole responder system in a bogus state (note that responder can be released only by touchEnd or touchCancel, so if there is no touchEnd that follows scroll event then ScrollView will remain the responder and this would break next touch interaction).

It is therefore crucial for the ScrollView to reset `isTouching` state when touchCancel arrives, as otherwise the next scroll event would incorrectly trigger responder change.

On top of that ScrollView seems to be the only component in RN's core that registers to handle touchEnd but ignores touchCancel, which stands agains the comment added to `RCTRootView.cancelTouches` [here](https://github.com/facebook/react-native/commit/c14cc123d#diff-9cd70243bd2af75c613e29972bb1b41cR127).

This problem is difficult to test with a pure RN native app, as on Android it does not surface because of the `responderIgnoreScroll` flag that is being added to every scroll event, and it essentially makes the responder system ignore scroll events so they would never trigger responder change. On the other hand on iOS the cancel events are pretty rare. With pure RN app they can only be triggered by a "system" level interaction (e.g. when system alert dialog appears or when home button is clicked and there is a touch interaction happening). This issue becomes more prominent when RN app is embedded in a more sophisticated application that may use [`RCTRootView.cancelTouches`](1e8f3b1102/React/Base/RCTRootView.h (L130)) method to block RNs gesture recognizers in some cases or with third-party libraries that deals with touch events like [react-native-gesture-handler](https://github.com/kmagiera/react-native-gesture-handler) that also calls into the method when native touch interaction is detected.

Mike Grabowski 4e1dfa48a2 Fix test suite when running on a feature branch
Summary:
Test suite for React Native version check relies on `ReactNativeVersion.js` file that is modified on a release branch (it contains values of a real version, not zeros).

That makes it impossible for the build to pass: https://circleci.com/gh/facebook/react-native/23494

This PR mocks it with zero values, just like we mock it in other suites. I am not sure if that is desired, but works for now.

Miron Pawlik 74146cb315 Make `react-native link` play nicely with CocoaPods-based iOS projects.
Summary:
The core React Native codebase already has full support for CocoaPods. However, `react-native link` doesn’t play nicely with CocoaPods, so installing third-party libs from the RN ecosystem is really hard.

This change will allow to link projects that contains its own `.podspec` file to CocoaPods-based projects. In case `link` detect `Podfile` in `iOS` directory, it will look for related `.podspec` file in linked project directory, and add it to `Podfile`. If `Podfile` and `.podspec` files are not present, it will fall back to previous implementation.

**Test Plan**
1. Build a React Native project where the iOS part uses CocoaPods to manage its dependencies. The most common scenario here is to have React Native be a Pod dependency, among others.
2. Install a RN-related library, that contains `.podspec` file, with `react-native link` (as an example it could be: [react-native-maps](https://github.com/airbnb/react-native-maps)
3. Building the resulting iOS workspace should succeed (and there should be new entry in `Podfile`)

Kevin Gozali 47bfbbb1d3 iOS: introduce RCT_EXPORT_SYNCHRONOUS_TYPED_METHOD() macro to provide the return type of a sync method
Summary:
This provides a way to customize the return type of a sync exported method, instead of just using `id`.

```
RCT_EXPORT_SYNCHRONOUS_TYPED_METHOD(NSString *, sync1:(NSString *)x)
{
  return @"hello";
}
```

The return type needs to be a sub type of `id` - so scalars like `double` won't work (the bridge will crash).

Sebastian Markbage 60c898d864 Persistent Yoga
Summary:
This is meant to show a possible route format for a persistent form of Yoga. Where previous layouts can remain intact while still taking advantage of incremental layout by reusing previous subtrees.

```c
YGNodeRef YGNodeClone(const YGNodeRef node);
```

The core of this functionality is a new API to clone an existing node. This makes a new detached node with all the same values as the previous one. Conceptually this makes the original node "frozen" from that point on. It's now immutable. (This is not yet enforced at runtime in this PR but something we should add.)

Since the original is frozen, we reuse the children set from the original node. Their parent pointers still point back to the original tree though.

The cloned node is still mutable. It can have its styles updated, and nodes can be inserted or deleted. If an insertion/deletion happens on a cloned node whose children were reused, it'll first shallow clone its children automatically.

As a convenience I also added an API to clear all children:

```c
void YGNodeRemoveAllChildren(const YGNodeRef node);
```

During insert/delete, or as a result of layout a set of reused children may need to be first cloned. A kind of copy-on-write. When that happens, the host may want to respond. E.g. by updating the `context` such as by cloning any wrapper objects and attaching them to the new node.

```c
typedef void (*YGNodeClonedFunc)(YGNodeRef oldNode,
                                 YGNodeRef newNode,
                                 YGNodeRef parent,
                                 int childIndex);

void YGConfigSetNodeClonedFunc(YGConfigRef config,
                               YGNodeClonedFunc callback);
```

This PR doesn't change any existing semantics for trees that are not first cloned.

It's possible for a single node to exist in two trees at once and be used by multiple threads. Therefore it's not safe to recursively free a whole tree when you use persistence. To solve this, any user of the library has to manually manage ref counting or tracing GC. E.g. by replicating the tree structure in a wrapper.

In a follow up we could consider moving ref counting into Yoga.
