Denis Koroskin 89cf5c49b9 Make FlatViewGroup implement ReactCompoundViewGroup interface
Summary: In FlatViewGroup, we flatten some react nodes into parent while mounting others into child Views. This is causing touch events being dispatched to wrong targets because child Views are \"stealing\" touch events from flattened Views. To fix the issue, implement ReactCompoundViewGroup to provide information about both virtual and non-virtual nodes.

Denis Koroskin b52928c484 Include non-virtual nodes when collecting NodeRegions
Summary: Before this patch, we only collected virtual nodes in NodeRegions, because NodeRegions are only needed to implement ReactCompoundView.reactTargetForTouch() which is only interested in virtual nodes. In the next patch, FlatViewGroup will implement ReactCompoundViewGroup interface which requires knowledge of both virtual and non-virtual children. As a step towards that, we need to include non-virtual nodes in NodeRegions. This patch is implementing that. By itself, it should have not cause any changes in application behavior: we add non-virtual nodes to NodeRegions and mark them as non-virtual, then skip all non-virtual nodes in reactTagForTouch().

Denis Koroskin 8014147013 Fix order of NodeRegions
Summary: Before the patch, order of NodeRegions was inconsistent. Given parent A and 3 children B, C and D, we collect DrawCommands like this: A, B, C, D but NodeRegions were collected as B, C, D, A which neither matches draw order, nor a reverse of it. This patch changes it so that NodeRegions are collected in drawing order (A, B, C, D) and we iterate backwards to find correct touch target (in case they overlap).

Denis Koroskin c75f3b7d9f Make sure we call notifyChanged(true) when a child is added to RCTVirtualText
Summary: CSSNode.addChildAt() calls dirty() to invalidate the node and propagate dirty flag up to the root. However, ReactShadowNode overrides dirty() for virtual nodes so it does nothing. This results in bugs where an added text doesn't trigger a measure pass because RCTText is never dirtied. To fix the bug, override addChildAt() in RCTVirtualText and explicitly call notifyChanged(true) to make sure hosting RCTText is dirtied and re-measured/re-laid out.

Denis Koroskin 0b560d3d3d Don't try to remove Views that about to be removed with the root View
Summary:
We keep a list of FlatShadowNodes that mount to Views that we want to delete, and only flush it at the end of an update cycle. This results in a situation where a root view is being removed before children are removed, which results in a crash in NativeViewHierarchyManager because a View that we are trying to remove no longer exists. There are a few approaches to fix the issue:
a) make a check if a View exists before removing it. While works, it removes a bug protection when we erroneously trying to remove a View that no longer exists (such as this). I'd prefer to keep the check in place
b) flush the views-to-drop queue. This works, but does some extra work in UI thread (namely, removing Views that would be removed anyway)
c) trim the views-to-drop queue to remove any Views that will be removed anyway. This does a tiny bit of extra work in BG thread, but less work in UI thread.

This diff implements option c).

Denis Koroskin 848bae2e95 Fix FlatUIImplementation.manageChildren() failing when moveFrom is not sorted
Summary:
Code in FlatUIImplementation.manageChildren() incorrectly assumed that moveFrom is sorted and moveTo is not, which is actually reverse: moveFrom is not sorted, and moveTo is. This means that we need to sort moveFrom before we can traverse it, and that we no longer need to sort moveTo (we did it by moving nodes to mNodesToMove first and then sorting it).

The sorting algorithm used is borrowed from Android implementation of insertion sort used in DualPivotQuicksort.doSort() when number of elements < INSERTION_SORT_THRESHOLD(32) which is 99.999% the case in UIImplementation.manageChildren() (most of the time this array is either empty or only contains 1 element).

Another (very rare) bug this is fixing is that the code only worked for FlatShadowNodes, but not all shadow nodes are FlatShadowNodes (there are rare exceptions, such as ARTShape, ARTGroup etc). New code works with all types of shadow nodes.

Denis Koroskin ada5234b0e Lazily create/update views
Summary:
There is a rare case in React Native when a hierarchy is created and then *immediately* discarded all in one transaction. This is causing a View leak, because a View is created and then never attached to a hierarchy because it shadow node got detached. Since we never attached the View to the hierarchy, we cannot do a detach either and the View is kept in NativeViewHierarchyManager forever, causing a View leak. To fix the issue, don't create a backing View whenever a shadow node mounts to a View. Instead, put the create request into a queue and ONLY execute it if a shadow node is still attached to a hierarchy. This is fixing the View leak because will not create a View unless it's going to be attached somewhere.

The same logic applies to View style update (we don't want to update a View that is going to be detached from a hierarchy).

Summary:
When layout happens, left/top/right/bottom coordinates (and thus clip-*, too) are sometimes not at a pixel boundary for 2 reasons:
a) width/height in Flexbox are floats, and can contain any value, not just a whole pixel. E.g. style={{width: 3.1415926}} is perfectly valid
b) floating point arithmetics sometimes leads to values barely outside of pixel boundaries (width 18.0f can become 18.000001f when a sibling/child size changes).

a) is \"breaking\" screenshot tests, which slightly but differ from reference implementation
b) causes extra View updates/redraws for no reason

This patch is rounding DrawCommand bounds to a whole pixel to avoid these 2 issues.

Denis Koroskin 674e74a963 Only clip node against its own boundaries IFF clipToBounds() is set to true (i.e. overflow is visible)
Summary:
Previously, every node would be clipped by its own boundaries. This made sense, because
a) RCTView cannot draw outside of its bounds, so clipping is harmless
b) all other node types were not allowed to control overflow behavior, and for them overflow was implicitly set to hidden, which means it should clip.

This diff changes the logic so that overflow can be set on any node (image, text, view etc).

The change has an important implication that make the diff a little trickier that it could be: AbstractDrawCommand clipping logic needs to be relaxed. Previously, clip bounds were *always* intersected with node bounds, which means that clip rect was always within node rect. This is no longer true, and thus shouldClip() logic needs to be modified.

Because of the above, RCTText no longer needs to artificially clip bounds against layout width/height.

Note: RCTImage is still not working with overflow: visible correctly (it still always clips). This is fixed in a follow up diff.

Summary:
There is an assert in FlatViewGroup.reactTagForTouch() that says that TouchTargetHelper should not allow returning getId() when pointer events are BOX_NONE. This is not entirely accurate.

This acturally method is invoked in 2 different contexts. Main context is to find a touch target, and in that context the method indeed should never return getId() if pointer events are BOX_NONE. There is however a TouchTargetHelper which actually expects that reactTagForTouch() *may* return getId(), in which case it will perform logic to not all this method be invoked again from main context.

In other words, this assert needs to be removed because it is entirely possible to return getId() when pointer events are BOX_NONE. Ideally, these would be 2 different methods, but ReactCompoundView interface only defines a single reactTagForTouch() method.

Denis Koroskin 461871364b Manually assign id of the top-level View to match top-level react tag
Summary:
Nodes create a FlatViewGroup for a root node element, and NativeViewHierarchyManager assigns it an id that matches root node it. Now this top-level FlatViewGroup is added to a ReactRootView. In non-nodes, this ReactRootView has an id that matches root View id, and when this ReactRootView gets detached from Window, it sends an event to NativeViewHierarchyManager that says that all the children of this View must be removed recursively. This works great in non-Nodes, but fails in Nodes because ReactRootView has no id (-1) and NativeViewHierarchyManager fails to find a corresponding ReactShadowNode, throwing an Exception. To fix the issue and make it work again we need to assign this View id of the top level shadow node. This creates a minor issue, where 2 Views (ReactRootView and its only child) share the same id, but that is not a problem because we don't enforce uniqueness of the ids, and don't rely on getViewById().

This was originally implemented, but then I removed it because I thought it wasn't truly needed. Turns out, it is needed.

Denis Koroskin e7d8d2c3ab Don't use NodeRegion to update View bounds
Summary: NodeRegions are touch regions within hosting View, and while in most cases they are the same as View boundaries, there is one case where it's not true: TextNodeRegion. When mounted to a View, TextNodeRegion will have a bounds of (0,0,width,height) which is clearly different from (left,top,right,bottom). Initially I assumed they would always be the same so we could use information stored in NodeRegion (should probably be called TouchRegion) to update node's View boundaries, but it breaks RCTTextView when it mount to a View (because it would either contain incorrect bounds, or View will be laid out incorrectly). Right now touch is not working on RCTView that mounts to a View. To fix the issue, separate the 2 concepts.

Denis Koroskin b321ea98d3 Properly clip child Views in FlatViewGroup
Summary:
Everything (but Views) are drawn using AbstractDrawCommand (or its derivative, like DrawBorder or DrawBackgroundColor) and supports clipping properly. Views however are drawn using an assumption that Android will clip them manually. This is however not always true. One example is if an element A mounts to a View, and its parent B doesn't but has overflow: hidden and thus should clip the child.

There are 2 ways to fix this:
- pop every element that has overflow: hidden to its own View. In this case, its children will always be correctly clipped. This is however very inefficient, especially if overflow: hidden is default (which it is!) which means that almost every React element must be backed by an Android View.
- add clipping information to DrawView, similar to how AbstractDrawCommand has it.

This diff implements the latter approach.

For example, a <View> element with size 200x200 with overflow:hidden should clip its child which is 400x400, but this didn't happen. However, if parent <View> would mount to an Android View, it would clip the child regardless of the overflow attribute value (because Android Views always clip whatever is drawing inside that View against its boundaries).

Summary: Previously, manageChildren() would throw an Exception if moveFrom != null or moveTo != null. This is obviously not correct, because no matter how rare these events are, they actually happen in practice. This diff re-implements manageChildren() to support all the cases. It does so by first removing all the elements that need to be removed. During removal, those elements that need to be moved will be temporarily put into `mNodesToMove` array. Then the next step is to add all elements (including new elements to add, and existing elements to move). There is an fast path when only one of another is present. If both types are present, they need to be sorted, first, to maintain correct orded. A similar optimization is applied to `removeChildren()`: there is a fast path when moveFrom == null and a another fast path when removeFrom == null. When both are != null, a merge sort is used (it is assumed that both moveFrom and removeFrom are sorted).

Denis Koroskin 529390b87c Fix children of AndroidView not being re-laid out after they call requestLayout
Summary:
In ReactNative, we are fully controlling layout of all the Views, not allowing Android to layout anything for us. This is done by making onLayout() of the top-level View in the hierarchy to be empty. This works fine because we explicitly call measure/layout for all the Views when they need to be re-measured or re-laid out. There is however one case where this doesn't happen automatically: some Android Views such as DrawerLayout or ActionBar have children that don't have shadow nodes associated with them (such as a title in ActionBar). This results in situations where children of AndroidView will call requestLayout but they will never get relaid out, because shadow hierarchy doesn't know about them. Example: ActionBar has a seTitle method that will internally call TextView.setTitle() and that TextView will call requestLayout because its size may have changed. However, that TextView will never be remeasured or relaid out.

This diff is fixing it by keeping track of everyone who called requestLayout. Then, at the end of the update loop we go over the list a manually remeasure and relayout those Views.

Not a huge fan of how this is implemented (there MUST be a better way) but this works with least efforts. I'll see if I can improve it later.

Summary:
There is currently a bug where we never release any Views that no longer display, still storing hard references in NativeViewHierarchyManager. This diff is fixing this bug, and here is how:

a) there is already logic in place to drop FlatShadowNodes (UIImplementation.removeShadowNode).
b) there is already logic in place to drop Views (NativeViewHierarchyManager.dropView(int reactTag) - used to private but needs to be protected so I can call it)
c) (the missing part) when we are about to drop a FlatShadowNode, check if it mount to a View (i.e. there is a View associated with that node), put it into a ArrayList. When we finished updates to a nodes hierarchy (which happens in non-UI thread), collect ids from those nodes and enqueue a UIOperation that will drop all the Views. We can either forward nodes as FlatShadowNode[], or only ids as int[]. Both should be fine, but as a rule of thumb we don't touch shadow node hierarchy from UI thread (as we don't touch Views from non-UI thread) so passing int[] is what this code is doing.

Denis Koroskin fbe1b61fe1 Cache CustomStyleSpan in RCTVirtualText
Summary: @public `RCTVirtualText` is creating a new `CustomStyleSpan` on every `applySpans()` call, which is not very efficient. We can cache and reuse unchanged `CustomStyleSpans` for efficiency. This patch is doing just that.

Adam Comella 1c32385344 Android: Fix native animation crash
Summary:
An exception is thrown when the native animation code attempts to play an animation on a view that hasn't been created yet. This can happen because views are created in batches. If this particular view didn't make it into a batch yet, the view won't exist and an exception will be thrown when attempting to start an animation on it.

This change eats the exception rather than crashing. The impact is that the app may drop one or more frames of the animation.

**Notes**

I'm not familiar enough with the Android native animation code to know whether or not this is a good fix. My team is using this change in our app because dropping animation frames is better than crashing the app. [This is the code](c612c61544/ReactAndroid/src/main/java/com/facebook/react/uimanager/UIViewOperationQueue.java (L874-L892)) that is creating the views in batches. Hopefully my PR at least provides some insight into the cause of the bug.

This may fix #9887

Konstantin Raev 0579efea8c Switched to npm hosted boost lib
Summary:
Boost is officially hosted on SourceForge which has ab SSL problem that Gradle complains about and also it is sometimes unavailable.
I switched to using npm hosted (yarnpkg mirrored for performance) boost lib exactly the same as from Source Forge.

Other alternatives considered:
- CDN e.g. mirror.nienbo.com started responding with 4XX code when requested by Gradle
- File sharing like DropBox are not for mass anonymous downloads
- Github is not good for binary files and is throttled for anonymous raw file downloads
- S3 or similar. Requires amazon account for maintenance and does not expose semver API and other nice features that npm has

In the future I'd like to try Yarn as dependency management tool for bridge builds, this could be the first step.

Adam Comella c0ea23cfb0 Android: Expose textBreakStrategy on Text and TextInput
Summary:
Android has a text API called breakStrategy for controlling how paragraphs are broken up into lines. For example, some modes support automatically hyphenating words so a word can be split across lines while others do not.

One source of complexity is that Android provides different defaults for `breakStrategy` for `TextView` vs `EditText`. `TextView`'s default is `BREAK_STRATEGY_HIGH_QUALITY` while `EditText`'s default is `BREAK_STRATEGY_SIMPLE`.

In addition to exposing `textBreakStrategy`, this change also fixes a couple of rendering glitches with `Text` and `TextInput`. `TextView` and `EditText` have different default values for `breakStrategy` and `hyphenationFrequency` than `StaticLayout`. Consequently, we were using different parameters for measuring and rendering. Whenever measuring and rendering parameters are inconsistent, it can result in visual glitches such as the text taking up too much space or being clipped.

This change fixes these inconsistencies by setting `breakStrategy` and `hyphenat

John Shelley f3c8158773 Android - ReactNativeHost getUseDeveloperSupport to public
Summary:
Currently React Native is opinionated in that the easiest approach is to extend ReactActivity. However to more easily allow integrating with existing application, we should allow some of the methods in ReactNativeHost to be public, and this is a very good first step.
* There is no harm in making this public from what I can tell.
* This allows `ReactNativeHost` to be more easily used outside of the `ReactActivity` and `ReactActivityDelegate` ecosystem. (A `ReactFragment` would be a good example)

_No issues found_

**Test plan (required)**

* Run any sample app and verify it still works.

Make sure tests pass on both Travis and Circle CI.

Kevin Lacker affd5ac681 Improve Android testing scripts
Summary:
The goal of this pull request is to make it easier for contributors to run Android tests locally, specifically the unit tests and integration tests. I added a bunch of checks to the local testing scripts that will warn you if your environment is misconfigured, and tell you how to fix it. I also updated the testing docs, so that the regular "Testing" page should be a decent resource to point people to when you are telling them "hey this pull request needs a test." Just Android, though, I haven't gotten to the iOS parts yet.

I also disabled a couple tests that seemed quite flaky while running on a local machine, and don't seem to be providing much value. In particular, the `TestId` test just hangs on my emulator a lot and has been flaky on CI in the past, so I removed about half of its test cases to make the sample app smaller. The testMetions test appears to be dependent on screen size so I commented it out.

John Shelley d21aa92480 Android - Fix Overlay for Marshmallow 23+
Summary:
Currently any React Native apps that target API 23 or greater will crash on the first initial debug/dev build due to the overlay permission.

Sadly there isn't a concrete "request permission" baked into the Marshmallow permission system.
However, we can launch the overlay screen without starting the react app and once its turned on start the app.

 - https://github.com/facebook/react-native/pull/10479 - Add the overlay permission information / Larger discussion around targeting API 23+
- Intent to Overlay permission goes directly to the app in question, rather then the general full listing of applications. This allows a developer who is not familiar with the system to easily toggle the overlay without getting confused.

Ben Clayton 833961e05d <Text> Expose Android's includeFontPadding property to JavaScript.
Summary:
By default Android will put extra space above text to allow for upper-case accents or other ascenders. With some fonts, this can make text look slightly misaligned when centered vertically.

We have found that the effect is very noticeable with certain custom fonts on Android. On iOS the font aligns vertically as expected.

Android exposes a property `includeFontPadding` that will remove this extra padding if set to false. This PR exposes that to JS, and adds it to the documentation and UIExplorer.

Yann Pringault fb230000a8 Call handleUpdateLayout even if the content didn't change
Summary:
This PR fixes #11096.

I don't know enough the ReactAndroid's source code so I don't know if this is correct but I hope it is.

In a recent commit (d4b8ae7a8a), the `dispatchUpdates` method now returns a boolean to dispatch or not the `onLayout` event. This works well but if the content is unchanged, the line `nativeViewHierarchyOptimizer.handleUpdateLayout(this);` is never called. I don't know if it was intended but it was this which introduces my issue. I called this again even if the content didn't change. This was the behaviour before 0.38 so I guess I didn't break anything.

I tested my pretty big app with this fix and every screen is ok.

Adam Comella 528a3c776a Android: Keep ScrollView content visible after edits
Summary:
Suppose that the user is scrolled to the bottom of a ScrollView. Next, the ScrollView's content is edited such that the height of the content changes and the current scroll position is larger than the new height of the content. Consequently, the user sees a blank ScrollView. As soon as the user interacts with the ScrollView, the ScrollView will jump to its max scroll position.

This change improves this scenario by ensuring that the user is never staring at a blank ScrollView when the ScrollView has content in it. It does this by moving the ScrollView to its max scroll position when the scroll position after an edit is larger than the max scroll position of the ScrollView.

Here are some pictures to illustrate how this PR improves the scenario described above:

Adam Comella aac8daf378 Android: Enable ad-hoc dependencies to be pre-downloaded
Summary:
ReactAndroid/build.gradle downloads a number of ad-hoc dependencies from the internet such as boost, JSC headers, and folly. Having the build depend on the internet is problematic. For example, if the site hosting the JSC headers was to go down, then CI builds would start failing.

This change introduces the environment variable REACT_NATIVE_DEPENDENCIES which refers to a path. Developers can pre-download all of the ad-hoc dependencies into that path and then the build process will grab the dependencies from that local path rather than trying to download them from the internet. This solution is in the spirit of the existing REACT_NATIVE_BOOST_PATH hook.

Venryx c4046d62a7 * Reduce emit overhead to ~50% of prior, by caching class-name of java-script module/interface.
Summary:
Made modification to react-native code that reduces the communication channel overhead to ~50% of prior, in some cases, by caching the class-name of the java-script module/interface.

For me it reduced the run-time of the RCTDeviceEventEmitter.emit function from 1438ms to 715ms, over a period of 8 seconds in my Android app. My project requires many emit calls, as I'm transferring real-time EEG data from a Muse headband to my react-native UI to be graphed, so this optimization was very helpful in my case.

Adam Comella 8b199a7fd0 Android: Enable apps to provide a custom configuration to Fresco
Summary:
The `FrescoModule` supports providing a custom image pipeline configuration. This module is created by `MainReactPackage` but `MainReactPackage` doesn't expose any way to customize the Fresco configuration. This change adds a parameter to `MainReactPackage`'s constructor so that the `FrescoModule`'s configuration can be customized by the app. A couple of design choices were made in this change:
  - `MainReactPackage`'s new constructor parameter is a `MainPackageConfig`. Introducing `MainPackageConfig` enables `MainReactPackage` to nicely support new optional configuration options in the future. Imagine the alternative of each optional configuration being a separate parameter to the `MainReactPackage` constructor.
  - `FrescoModule` exposes its default configuration as a builder object through the `getDefaultConfigBuilder` method. This enables app's to start with `FrescoModule`'s default configuration and then modify it.

Summary:
When using text inputs inside a ScrollView with `keyboardShouldPersistTaps=false` (default behavior) tapping another text input dismisses the keyboard instead of keeping it open and focusing the new text input which I think is the better and expected behavior.

Connor McEwen 51efaab120 Handle "Never Ask Again" in permissions and add requestMultiplePermissions
Summary:
In order to get featured in the Google Play Store, we had to handle a few specific cases with permissions based on feedback from the editorial team.

First, which was previously possible with this permissions module was bumping the sdk to version 23.

The second is requesting multiple permissions at one time. In order for the camera + upload to work, we needed to request both camera permissions + media storage in one flow.

The last is handling the case where the user checks the "Never Ask Again" box. This will only appear after a user denies a permission once and is then prompted again. The logic for handling this case is taken from here: http://stackoverflow.com/questions/31928868/how-do-we-distinguish-never-asked-from-stop-asking-in-android-ms-runtime-permis/35495372#35495372

Benoit Lemaire 6fef014295 Remove Jackson dependency
Summary:
This PR removes dependency to Jackson third-party library in Android React Native.

Looking at some older PRs that got merged, it seems like some work had already been done to move away from Jackson.

Anyway, there was only two classes left with a dependency on Jackson. I refactored the code to use android built-in `JsonReader` and `JsonWriter` classes instead.

Prep work was done in https://github.com/facebook/react-native/pull/10516 introducing a few unit tests around serialization, to make sure that refactoring around serialization would not break things.

All references to Jackson in build systems files (BUCK files & build.gradle) have also been removed now that no code depend anymore on this third-party library.

Motivation behind this work is that third-party dependencies in Android React Native can prove to be a pain when trying to integrate React Native components into an already existing large Android application (I know this is not the most common use case for react-native ... yet ;P), that might a

Adam Comella 1b870d2019 Android: Add disableExtractUI prop to TextInput on Android
Summary:
On Android, if there is a small amount of space available around a text input (e.g. landscape orientation on a phone), Android may choose to have the user edit the text inside of a full screen text input mode. This behavior isn't always desirable. For example, if your app offers some UI controls for controlling the formatting of the text, you want the controls to be visible while the user is editing the text. This Android feature conflicts with that desired experience because the UI controls would be hidden while the text is being edited.

The `disableExtractUI` prop enables developers to choose whether or not Android's full screen text input editing mode is enabled. When this prop is true, Android's `IME_FLAG_NO_EXTRACT_UI` flag is passed to the `setImeOptions` method.

**Test plan (required)**

Verified `disableExtractUI` works for both `true` and `false` values in a test app.

My team is also using this change in our app.

Andy Street 68c6d71cea BREAKING [react_native] Don't create CSSNodes for virtual shadow nodes
Summary:
Virtual shadow nodes (e.g. text) don't use CSSNodes so we don't need to create them. This shows large savings in CSSNodes allocated, depending on the app.

This could be breaking if:
- You have virtual nodes that still set and get CSS properties. The setters now no-op for virtual nodes (I unfortunately couldn't remove them completely -- see the comment on LayoutShadowNode), but the getters will NPE. If you see these NPE's, you should almost definitely be using your own datastructure instead of a CSSNode as virtual nodes will not participate in the layout process (and the CSSNode is then behaving just as a POJO for you).

I do not anticipate this to be breaking for anyone, but am including breaking in the commit message since this is a change in API contract.

Summary:
Currently, The **DatePickerAndroid** component opens the native date picker with default mode. We can't able to change the mode via configurations. To support android **[date-picker mode](https://developer.android.com/reference/android/widget/DatePicker.html)**, existing component needs to be changed.

**For Android >= 5.0**, The DatePickerDialog doesn't provide the default method to change the mode of a date picker.  So I have added custom theme which will support two kinds of **mode('spinner','calendar')** ref:https://developer.android.com/reference/android/R.attr.html#datePickerStyle.

**For Android < 5.0,** The DatePickerDialog provides the default method to change the mode of a date picker. ref:https://developer.android.com/reference/android/widget/DatePicker.html#setCalendarViewShown(boolean).

With the help of **Build.VERSION.SDK_INT** I have done the above functionality with limited lines of code changes and also I have added the example to UIExplorer.

Adam Comella ea913e4691 Android: Update coalesce to prefer newest event
Summary:
The only callsite of `coalesce` looks like this:

```
newEvent.coalesce(oldEvent);
```

The default `coalesce` implementation returns the event with the most recent timestamp. When the events have the same timestamp then, using the variable names from above, `coalesce` returns `oldEvent`.

This change updates `coalesce`'s implementation to make it explicit that it returns `this` (`newEvent` in the variable names from above) in the case of a tie.

The motivation for this change is related to scroll events. In my team's app, we were seeing scroll events being emitted with the same timestamp and the coalescing logic was causing the oldest scroll event to be chosen. This was causing our JavaScript code to receive stale scroll information and the way the JavaScript code utilized this stale scroll information resulted in the ScrollView settling on the wrong scroll position.

Verified that scroll events work properly in a ScrollView in a test app. Also, my team's app uses this

Andy Street d63ba47b59 BREAKING [react_native] Move to new C-based implementation of css-layout in RN Android
Summary:
Moves from CSSNodeDEPRECATED to CSSNode. This has shown to be a huge performance win for layout time within FB.

This is BREAKING because CSSNode contains bug fixes that were not migrated to CSSNodeDEPRECATED which may change the way your layout appears. The most common of these by far involves `flex: 1`.

Previously, developers had to put `flex: 1` in many places it didn't belong in order to work around a bug in css-layout. Now `flex: 1` is treated properly and, unfortunately, this means that your layout may no longer look correct. Specifically, you may see that your layout looks collapsed, or children don't render. The fix is to simply remove `flex: 1` from those containers.

Adam Comella e87e181998 Android: Expose Image's onError event to JavaScript
Summary:
iOS supports an Image onError event. Android was firing the event but it was never reaching JavaScript because Android didn't include this event in `getExportedCustomDirectEventTypeConstants`.

**Test plan (required)**

Verified that the `onError` event now fires in a test app.

My team uses this change in our app.

Pete Huitsing 191db90345 Prevent null header value from raising exception
Summary:
In the wild, our app will occasionally crash with:
```
Fatal Exception: java.lang.NullPointerException
value == null
```

The stack trace brings it back to `okhttp3.Headers$Builder.checkNameAndValue (Headers.java:316)`:
```
if (value == null) throw new NullPointerException("value == null");
```

In the proposed fix, we simply continue the documented functionality of the `extractHeaders` method by returning "null" for invalid data.

Christian Brevik da4df3f12f Make ReactWebView & Client protected
Summary:
I'd like to make `ReactWebView` and `ReactWebViewClient` `protected` instead of `private`, inside the `ReactWebViewManager` class. The reason being that if you extend the `ReactWebViewManager` it'll be much easier to override existing logic.

In my specific case I'd like to be able to override [shouldOverrideUrlLoading](https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/react/views/webview/ReactWebViewManager.java#L120) inside `ReactWebViewClient` and handle custom URL schemes differently. See #10055.

Andy Street 0df65bb7d4 BREAKING [react_native/css_layout] Update RN shadow nodes to hold CSSNode instead of extending CSSNode
Summary:
This diff makes it so ReactShadowNode holds a CSSNode instead of extending one. This will enable us to pool and re-use CSSNodes and will allow us to keep from breaking the CSSNode api assumption that nodes that have measure functions don't have children (right now, text nodes have measure functions, but they also have raw text children).

BREAKING
This diff makes ReactShadowNode no longer extend CSSNodeDEPRECATED. If you have code that depended on that, e.g. via instanceof checks, that will no longer work as expected. Subclasses that override getChildAt/addChildAt/etc will need to update your method signatures. There should be no runtime behavior changes.
