- [x] Target the `master` branch, NOT a "stable" branch.

Fixes #14081. Prevents unnecessary error output on check for yarn package manager on Windows systems.

Can't find existing tests for the CLI and JavaScript doesn't have much knowledge about this change anyhow.

Example behavior with and without the fix:

Note that on master, the output contains the line "'yarn' is not recognized as an internal or external command, operable program or batch file." and on my branch, it does not.

Valentin Shergin 3df537a25c Using `drawViewHierarchyInRect` instead of `renderInContext` for snapshot tests
Summary:
We found that `-[CALayer renderInContext:]` produces bad results in some cases (which is actually documented thing!),
so we decided to replace it with `-[UIView drawViewHierarchyInRect:]` which is more reliable (I hope).
As part of this change I completly removed support of `CALayer` from local fork of `RNTesterIntegrationTests`.

See https://github.com/facebook/react-native/pull/14011#issuecomment-303844580 for more details.

Chris Knepper cc1a4b0915 Clarify documentation for ScrollView component
Summary:
The documentation for the prop `scrollEnabled` on the `ScrollView` component does not clarify that scrolling is still possible by calling `scrollTo` on the view ref.

Please see [this expo snack demo](https://snack.expo.io/BJKTVMM-Z) showing scrolling is allowed while `scrollEnabled` is `false`.

This PR makes the documentation for this prop more clear, in that setting it to false will only disable scrolling by touches, not universally.

In my opinion, this also raises the question of a need for an additional prop which would disable all scrolling, even when calling `scrollTo`.

I have attached a screenshot of what this part of the documentation looks like with my edit:

Jean Lauliac 21e3d4db20 packager: Module: get rid of callbacks
Summary: By getting rid of callbacks, we get a code that's pretty halved in size, and much easier to read, but we also fix bugs! When some of the code of Module would throw, we wouldn't catch it, meaning that packager would crash entirely. That's the case for when we have a Haste name mistach, for example. This changeste fixes that by instead capturing exceptions through the Promise chain, that bubble up all the way to the `Server` and reasonnably handled. People can then fix the Haste nane mismatch and refresh right away, and it'll work as expected.

Janic Duplessis c87524e0a6 Native Animated: Prevent views driven by native animated from being optimized away
Summary:
When using native animated we don't go through the shadow thread and use the NativeViewHierachyOptimizer so we have to make sure the views won't get optimized away. Also since we are not passing certain props because they are driven by native it is possible that the view will be marked as layout only when in fact it is not.

**Test plan**
Animated a simple view that will be collapsed with native animated and reproduce the error (it's actually just an error log in logcat now and no longer a redscreen) and checked that this fixes it.

This changeset introduce a simple test that just test the `buildBundle` public API. On the same model, I'd like to test the server API and behavior, and things such as hot module reloading.

Adam Comella e40d1a1065 iOS: Introduce API for moving screen reader's focus
Summary:
This change introduces an API, `setAccessibilityFocus`, which moves the screen reader's focus to the passed in element. This causes VoiceOver to announce the element and draw a focus rectangle around it.

Similar functionality is already available in RN Android through the `sendAccessibilityEvent` method. Here's an example of what exists today in RN Android:

```
RCTUIManager.sendAccessibilityEvent(
  node,
  8 /* TYPE_VIEW_FOCUSED */);
```

Called `setAccessibilityFocus` on a couple of elements to verify that focus does indeed move when VoiceOver is enabled. Additionally, my team is using this change in our app.

Valentin Shergin 35393524a9 Fixed <TextInput>.onContentSizeChange on Android
Summary:
Previously <TextInput>'s onContentSizeChange event fires very rearly, usually just once after initial layout. This diff fixed that.
I also considered to a bunch of another things to get the native notification, but I found that overriding `onTextChanged` is the most reliable, easy and effitient way to implement this.

I tried/considered:
 * onLayout (does not fire)
 * OnPreDrawListener (fires to often)
 * OnGlobalLayoutListener (does not fire)
 * OnLayoutChangeListener (does not fire)
 * isLayoutRequested (too hacky)

(I also fixed the <AutoExpandingTextInput> demo to illustrate the fix.)

And just heads up, we will remove `contentSize` info from `onChange` event very soon.

Jason Noah Choi ff78a8de22 Add newly recommended method for RCTLinkingManager due to deprecation
Summary:
What existing problem does the pull request solve?

Beginning in iOS9, Apple has deprecated `-application:openURL:sourceApplication:annotations:`

`- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation NS_DEPRECATED_IOS(4_2, 9_0, "Please use application:openURL:options:") __TVOS_PROHIBITED;`

This PR uses the newly recommended method:

`- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)`

while meanwhile, leaving the deprecated one for developers wishing to use the older `-application:openURL:sourceApplication:annotations:` for apps that support versions 8.x or less.

Benefits will include:
- [x] less warnings
- [x] official deprecation should happen when iOS 11 is deployed
- [x] TVOS support

Caleb Meredith f702cbecba Render section footer in <SectionList> sections with no data
Summary:
Fixes https://github.com/facebook/react-native/issues/13784

The section footer was only rendered with the last item of the section. However, that meant in sections where no items were rendered, no section footer would be rendered. This patch makes sure that when there are no items the section footer is rendered with the section header in addition to adding tests asserting the existance of section footers in empty lists.

One potential point of contention is whether or not a section separator (as defined by the `SectionSeparatorComponent` prop to `<SectionList>`) should be rendered in an empty list. I did not include a section separator for empty lists, but let me know if you think one should be included. See the test plan below for an image of an empty section rendered without a section separator.

I was also running into a lint error, `no-alert`, in `SectionListExample.js` around line 135 that blocked me from publishing. This error looks to be triggered when the `alert()` global function is called, so to fix the error I added an import for the `Alert` module and called the `alert()` function on that module.

To help debug the `scrollToLocation()` behavior that was modified as a part of this PR I added three buttons (can be seen in the test plan image) which scroll to arbitrary points in the list.

Janic Duplessis fc45471af2 Native Animations - Fix edge case with restore default values
Summary:
There was an edge case where sometimes a view could be added and removed in the same batch so this caused issues because we ran `disconnectAnimatedNodeFromView` before `connectAnimatedNodeToView`. This separates restoring default values from `disconnectAnimatedNodeFromView` so we can run only `restoreDefaultValues` on the pre-operations queue and just do nothing in case the view doesn't exist (it is fine because we know it will be removed immediately).

**Test plan**
Tested that native animations still work properly in RNTester and tested that the edge case crash was fixed.

Jean Lauliac a4badb8471 packager: TransformCaching: make choice of cache explicit in the API
Summary:
This changeset moves the creation of the transform cache at the top-level of the bundler so that:

* we can use alternative folders, such as the project path itself, that I think will be more robust especially for OSS;
* we can disable the cache completely, that is useful in some cases (for example, the script that fills the global cache).

The reasons I believe a local project path is more robust are:

* there are less likely conflicts between different users and different projects on a single machine;
* the cache is de facto cleaned up if you clone a fresh copy of a project, something I think is desirable;
* some people have been reporting that `tmpDir` just returns nothing;
* finally, it prevents another user from writing malicious transformed code in the cache into the shared temp dir—only people with write access to the project have write access to the cache, that is consistent.

ashoat 803a9168f2 Pass data prop instead of props to _updateViewableItems in _onScroll
Summary:
This is a simple bugfix. `_updateViewableItems` expects the `data` prop, as it calls `getItemCount` on it. Without this, `onViewableItemsChanged` updates twice for each scroll position, once from `_onScroll` with the incorrect results, and once from `_updateCellsToRender` with the correct results. This means the callback nigh-on unusable.

I simply logged the results of `onViewableItemsChanged` and made sure they were correct.

What existing problem does the pull request solve?

ViewManagersPropertyCache, ViewManagerPropertyUpdater static field not release when ReactInstanceManager called destroy.

I use this url to integrate RN:
[http://facebook.github.io/react-native/docs/integration-with-existing-apps.html](http://facebook.github.io/react-native/docs/integration-with-existing-apps.html)
and in Activity's onDestroy function add the follow code to release RN:
```java
mReactInstanceManager.destroy();
mReactInstanceManager = null;
```
and then when I exit activity, find the static field not release.

Adam Comella 35338e9008 iOS: Avoid adding extra spaces to accessibility label
Summary:
In some cases, `RCTRecursiveAccessibilityLabel` could return an accessibility label that had leading space, trailing space, or multiple spaces between words. This is because it always added a space before adding a label even if the label turned out to be empty.

This is fixed by being stricter about adding spaces.

Found test cases that used to introduce leading space, trailing space, or multiple spaces between words and verified that there aren't any extra spaces after the fix.

```
{/* Used to have leading space */}
<View accessible={true}>
  <View />
  <View accessibilityLabel='Two' />
  <View accessibilityLabel='Three' />
</View>

{/* Used to have 2 spaces between "One" and "Three" */}
<View accessible={true}>
  <View accessibilityLabel='One' />
  <View />
  <View accessibilityLabel='Three' />
</View>

{/* Used to have trailing space */}
<View accessible={true}>
  <View accessibilityLabel='One' />
  <View accessibilityLabel='Two' />
  <View />
</View>
```

Additionally, my team is using this fix in our app.

Daniel Cestari fe229f8104 Move to{HashMap,ArrayList} up to Readable{Map,Array}

Thanks for submitting a PR! Please read these instructions carefully:

- [x] Explain the **motivation** for making this change.
- [x] Provide a **test plan** demonstrating that the code is solid.
- [x] Match the **code formatting** of the rest of the codebase.
- [x] Target the `master` branch, NOT a "stable" branch.

NativeReadable{Map,Array} classes have convenient to{HashMap,ArrayList}
methods that make it easier to interoperate with existing Java code
from within a ReactNative application (e.g., Native Module)

These changes make these same methods available to any code using
the Readable{Map,Array} interfaces, instead of forcing consumers to
cast their generic instances into the NativeReadable* equivalents

Moving this methods up to the interfaces also makes it easier to
write unit tests for Native Modules - using the JavaOnly{Map,Array}
implementations of Readable{Map,Array} - while still relying on the
to{HashMap,ArrayList} methods

* Write a native module that receives a JSON object as `ReadableMap` and a JSON array `ReadableArray`.
* Print out the result of `toHashMap` and `toArrayList`.
* Make sure `NativeReadable{Map,Array}` works:
  * Call the native module's method from JavaScript, passing an `Object` and an `Array`.
  * Compare the printed values with the passed content.
* Make sure `JavaOnly{Map,Array}` works:
  * Call the native module's method from the Java code and pass a `JavaOnlyMap` and a `JavaOnlyArray`.
  * Compare the printed values with the passed content.

**Please advise if there is an automated test suite where I could add a case for this.**

Christoph Pojer 17e0478cf4 Remove setupBabel call from main entry point
Summary:
* Internally, we already set up babel before calling into metro-bundler.
* Externally, I moved the setup calls to outside the packager/ folder.

If somebody has a custom integration with RN, they would need to setup babel themselves up until we make the open source split. By the time this is released in open source, an npm version of metro-bundler will be available for use.

Next step: also do this for the worker and remove setupBabel from the metro repo.

Valentin Shergin 9637dd4a1b Introducing <ImageBackground>, replacement for <Image> which supports nesting views
Summary:
We are removing support of nesting views inside <Image> component. We decided to do this because having this feature makes supporting `intrinsinc content size` of the `<Image>` impossible; so when the transition process is complete, there will be no need to specify image size explicitly, it can be inferred from actual image bitmap.

And this is the step #0.

<ImageBackground> is very simple drop-in replacement which implements this functionality via very simple styling.
Please, use <ImageBackground> instead of <Image> if you want to put something inside.
