Valentin Shergin c194c18126 Fixed performance regression in `ShadowView`s layout process
Summary:
This fixes perf regression which was introduced by recent refactoring of the layout process.
That is how it used to be:
114c258045/React/Views/RCTShadowView.m (L160-L166)
Note: We have to resert this flag in indication that we already applied those changes and we don't need to traverse this subtree until it is changed again.

siddhantsoni 16c9e5b715 Fix: Added scroll Bounds check in scrollToOffset method in RCTScrollView on iOS
Summary:
<!--
Thank you for sending the PR! We appreciate you spending the time to work on these changes.

Help us understand your motivation by explaining why you decided to make this change.

You can learn more about contributing to React Native here: http://facebook.github.io/react-native/docs/contributing.html

Happy contributing!

-->

The scrollToOffset method of RCTScrollView for iOS does not include bound check for the scroll offset provided to the method. This can cause the whole view to scroll out of screen if the offset provided is greater than the bounds of the View.
The same does not happen on Android, where the scroll halts once the last item of the scrollView is in the viewport.
I have added bounds check so the offset resets to the MaxOffset which makes sure the view does not scroll out of the viewport.

The issue can be observed in the following snack:
https://snack.expo.io/H1363Uo8f

To test my changes I ran the code provided in the snack above with the react-native dependency pointing to my branch. As can be see in the video attached below, the scroll halts once it hits the end of the ScrollView even if the scroll offset provided is higher than the bounds of the ScrollView. It also does not scroll up for negative scroll offset.

Valentin Shergin ceb1d1ca5b Removing our own implementation of round-to-pixel algorithm
Summary:
> Okay, I don't remember where we first met
> But hey, admitting is the first step

This issue has a looong history.
The original algorithm was introduced by Nick Lockwood (nicklockwood Hey Nick! We miss you!) a while ago and from the very beginning this has one small error that basically makes it useless (try to find it yourself, it's fun!)
The problem was discovered and fixed twice (D4133643, D4983054), but every time we found that our <Text> infra was not ready for this, so we reverted and abandoned the change. As part of the last attempt to finally solve the issue, I ported the algorithm to Yoga where it lives today and works very well for Lytho and CK.
For now, the vision is clear:
 * The basic algorithm should live in Yoga for unification and performance reasons.
 * We still have to have `absolutePostion` as part of this API because it might be useful for some components which implement its own custom/non-Yoga-based layout.
 * We have to enable it in RN eventually.

So, this is the first step: Removing old, broken code which we don't plan to fix and use.

Make React Native crisp again!

Vojtech Novak ed5872e2cc Make sure refreshControl shows up on initial render if specified
Summary:
[this commit](2e1707d0e6) which was just a small refactor broke refreshControl behavior - if we render FlatList with refreshing=true, the refreshControl won't be visible on initial render.

The problem is, the [previous beginRefreshing method](2e1707d0e6 (diff-cfafa8d7e42ab87ab863f917e187a4aeL51)) was renamed to `beginRefreshingProgramatically` and the old call was left in one place [here](2e1707d0e6 (diff-cfafa8d7e42ab87ab863f917e187a4aeR47)).

Now, I am not sure what kind of jumping the mentioned commit was fixing, but since this fix only concerns the initial render, I believe it will not influence the jumping fix.

I have tested this locally in my app, can provide a video if needed.

Valentin Shergin 2716f53220 The New <Text> on iOS
Summary:
This is a complete rewrite of RCTText, the part of React Native which manages Text and TextInput components.

Key points:

* It's understandable now. It follows a simple architectural pattern, and it's easy to debug and iterate. Text flow layout is a first-class citizen in React Native layout system now, not just a wired special case. It also brings entirely new possibilities such as nested interleaving <Text> and <View> components.
* All <Text>-specific APIs were removed from UIManager and co (it's about ~16 public methods which were used exclusively only by <Text>).
* It relies on new Yoga measurement/cloning API and on-dirty handler. So, it removes built-in dirty propagation subsystem from RN completely.
* It caches string fragments properly and granularly on a per-node basis which makes updating text-containing components more performant.
* It does not instantiate UIView for virtual components which reduces memory utilization.
* It drastically improves <TextInput> capabilities (e.g. rich text inside single line <TextInput> is now supported).

Builds off of cae7179c94

- Make the prop a dictionary for more configuration options
- Rename `maintainPositionAtOrBeyondIndex` -> `maintainVisibleContentPosition` + `minIndexForVisible`
- Add autoscroll threshold feature

Given the async native of RN JS and background layout, there is no way to trigger the scrollTo from JS without risking a delay, so we add the feature in native code.

Spencer Ahrens cae7179c94 new feature to support smooth bi-directional content loading
Summary:
== Problem / Background ==

Most lists paginate in a single direction (standard infinite list), but some paginate in both directions. Most common example is a chat thread where new messages show up on the bottom, and old content can be loaded by scrolling up. Comment threads are another example.

Right now, adding content to the bottom of a scroll view is smooth - the content doesn't jump. But when adding to the top of the scrollview, the content gets pushed down, which is jarring (note this may appear reversed because of inverting the list which is common for chat applications).

== Approach ==

The basic idea is simple - we set a flag in JS, then for every uimanager transaction, we record which is the first eligible and visible view in the ScrollView, and compare it's new origin to the old one. If it has changed, we update the contentOffset of the ScrollView to compensate.

This is done by observing `willPerformMounting` directly (only from scrollviews that have this new property set), and then observing the prev state with prependUIBlock and making the update synchronously in addUIBlock to avoid any flicker.

There is also a way to skip views that we don't care about, like a spinner at the top of the view that we don't want to stay in place - we actually want it to get pushed up by the new content, replaced visually in the viewport.

== Notes ==

Most chat applications will probably want to do a scrollToTop when new content comes in and the user is already scrolled at or near the bottom.

This is glitchy if visible children are re-ordered, which could be fixed with additional logic, but it doesn't come up in the type of applications we're targetting here so punting on that.

== Test Plan ==

Valentin Shergin d2dc451407 reactBridgeDidFinishTransaction was finally removed
Summary:
We are removing `reactBridgeDidFinishTransaction`.
Why?
 * It is a performance drain. Supporting this requires dispatching main-thread block on every single transaction complete;
 * It has "too broad" non-conceptual semantic which encouraged using this as a "band-aid solution" for poorly designed components;
 * It is conceptually incompatible with new approaches that we are trying to implement to optimize the render layer;
 * It was deprecated for very long time.

This diff replaces usage of `reactBridgeDidFinishTransaction` with `uiManagerDidPerformMounting` which has very similar semantic except that fact that `uiManagerDidPerformMounting` is called asynchronously on the next run loop tick.

This diff removes `reactBridgeDidFinishTransaction` from RCTScrollView component. As I mentioned, because of the semantic of `reactBridgeDidFinishTransaction` is extremely broad, it's hard to capture what exact case it should handle. Based on comments and existing logic, it seems it tight to `contentSize` property and the size of RCTScrollContentView.

Eric Davison 36ad813899 Adding support for custom accessibility actions on iOS.
Summary:
This feature has been requested by customers.  Our previous (pre-react) application had support for custom accessibility actions.

This feature allows UI elements to provide a list of custom actions that can be read when VoiceOver is enabled.  UI elements expose one accessibility action by default.  Some UI elements may support multiple actions though other mechanisms like tap and hold.  To expose these actions in an accessible way iOS provides custom accessibility actions.

Feature was tested in the iOS simulator using the Accessibility Inspector.  Custom actions were added to a button and observed in the tool.  Custom actions were also invoked using the tool and then stepped through in the debugger.

The feature was also tested on an iPhone.  VoiceOver was enabled on the device and custom actions were observed for controls that exposed them.

We have been using this feature in our app for some time as well.

chendo 19b0a65c5e Improve accessibilityLabel performance
Summary:
Integration testing with Appium on iOS is slow. Profiling with Instruments.app points to `RCTView`'s `accessibilityLabel` method being a hot point in React Native, due to the `RCTRecursiveAccessibilityLabel` function.

I did a baseline benchmark by using Appium's `find_element(accessibility_id: <label>)` call on our application 10 times and got a baseline result of 0.6s for one of our primary screens.

After implementing the change and performing the same call 10 times, I got 0.48s for the same call, for a 20% performance increase in `find_element`.

Douglas 45185947ee Fix tvOS compile issues; enable TVEventHandler in Modal (fix #15389)
Summary:
**Motivation**

Fix an issue (#15389) where `TVEventHandler` would not work when a modal was visible.  The solution adds the gesture recognizers from the native `RCTTVRemoteHandler` to the native modal view (except for the menu button recognizer, which still needs special handling in modals).  This PR also fixes some breakages in compiling React Native for tvOS.

**Test plan**

Compilation fixes should enable tvOS compile test to pass in Travis CI.

The modal fix can be tested with the following component, modified from the original source in #15389 .

``` javascript
import React, { Component } from 'react';
import ReactNative from 'ReactNative';
import {
    Text,
    View,
    StyleSheet,
    TouchableHighlight,
    TVEventHandler,
    Modal,
} from 'react-native';

export default class Events extends Component {

    constructor(props) {
        super(props);

        this.state = {
            modalVisible: false,
        };
        this._tvEventHandler = new TVEventHandler();
    }

    _enableTVEventHandler() {
        this._tvEventHandler.enable(this, (cmp, evt) => {
            const myTag = ReactNative.findNodeHandle(cmp);
            console.log('Event.js TVEventHandler: ', evt.eventType);
            // if (evt.eventType !== 'blur' && evt.eventType !== 'focus') {
            //  console.log('Event.js TVEventHandler: ', evt.eventType);
            // }
        });
    }

    _disableTVEventHandler() {
        if (this._tvEventHandler) {
            this._tvEventHandler.disable();
            delete this._tvEventHandler;
        }
    }

    componentDidMount() {
        this._enableTVEventHandler();
    }

Robert Paul fd9c3618fc - Adding locale prop to DatePickerIOS
Summary:
<!--
Thank you for sending the PR! We appreciate you spending the time to work on these changes.

Help us understand your motivation by explaining why you decided to make this change.

You can learn more about contributing to React Native here: http://facebook.github.io/react-native/docs/contributing.html

Happy contributing!

-->

While building a React Native application, I've come across the use case of wanting to set a specific locale for DatePickers irrespective of the users OS region setting. Since this is a feature available to native DatePicker components, I think it would be helpful to expose this in React Native as well.

Testing can be done by passing a `locale` prop to a DatePickerIOS. Example:

```
<DatePickerIOS
  date={this.state.date}
  mode="date"
  locale="fr_FR"
  onDateChange={date => this.setState({ date: date })}
/>
```
