Summary:
== Before ==
- Aspect ratio would do its best to fit within it's parent constraints
- Aspect ratio would prioritize `alignItems: stretch` over other sizing properties.
== After ==
- Aspect ratio is allowed to make a node grow past its parent constraints. This matches many other aspects of flexbox where parent constraints are not treated as hard constraints but rather as suggestions.
- Aspect ratio only takes `alignItems: stretch` into account if no other size definition is defined. This matches the interaction of other properties with `alignItems: stretch`.
== Updating your code ==
**You probably don't need to do anything** but in case something does break in your product it should be as easy as adding `{width: '100%', height: '100%', flexShrink: 1}` to the style declaring the `aspectRatio`.

Summary:
Currently, `onLoadStart` fires for a couple of cases:
1. toplevel page loads (e.g. initial page load, clicking links)
2. loading of pages within an iframe
The fact that `onLoadStart` fires for case (2) causes some problems. For example, it makes it difficult for the code that uses the WebView to know what URL the WebView is currently rendering. This is because the listener can't distinguish between the toplevel URL and the URL of an iframe. Additionally, this behavior is inconsistent with the behavior on iOS. On iOS, `onLoadStart` only fires for toplevel page loads.
To fix these issues, this change deletes the `doUpdateVisitedHistory` handler so that `onLoadStart` only fires for case (1).
**Test Plan**
Created a test page that has an iframe and loaded it in the WebView. Verified that `onLoadStart` only fires for toplevel page loads.

Summary:
Overview -
This PR resolves the issue described in #14606. This PR makes Text components take into account the includeFontPadding property when calculating their size.
Background -
Currently, on Android, when includeFontPadding is set to false, the React Text component does not adjust its height. This makes it difficult to lay out other components at a precise spacing relative to a Text component.
iOS calculates the height of a UILabel based on the font's descent + ascent.
Android lets you choose whether to calculate the height of a TextView based on the font's top + bottom (includeFontPadding=true) or ascent + descent (includeFontPadding=false).
In order for a text component to be the same size on iOS and Android (relative to the rest of the layout in points and dips), one should set includeFontPadding=false on Android - but the React Text component needs to take this property into account when sizing itself for this to work.
Please see this stack overflow post for a visual explanation of the difference between a font's ascent/descent and top/bottom - https://stackoverflow.com/questions/27631736/meaning-of-top-ascent-baseline-descent-bottom-and-leading-in-androids-font
Testing -
Please see the attached screenshots to see the height difference of a Text component with this PR when includeFontPadding is true vs false.
The font I am using has an ascent + descent = em-size so that the height of the Text component will be equal to the font-size for a single line of text. This is to clearly show the additional height that includeFontPadding=true adds to the Text component.
For Text components that are styled in the same way,
When includeFontPadding=true, height = ~29.714 dips
When includeFontPadding=false, height= 24 dips

Summary:
When the AppState module is initialized, it subscribes to the `appStateDidChange` event and sends an async native method call to the AppState native module. There is a small race condition window where the native module can read the current app state as `uninitialized` before calling the JavaScript callback, and then be interrupted by the underlying mechanism to trigger the `appStateDidChange` event. If the `appStateDidChange` event is processed before the JavaScript callback, the resulting value of `AppState.currentState` will be invalid.
FixesMicrosoft/react-native-windows#1300
(Write your test plan here. If you changed any code, please provide us with clear instructions on how you verified your changes work. Bonus points for screenshots and videos!)
I simulated (over-exaggerated) the race condition by injecting "thread sleep" calls in the native method call and the native mechanism for updating the app state.
I then ran the AppStateExample in the RNTester and found that the current app state was set to `uninitialized`, as opposed to the expected value of `active`.
Once I made this JavaScript change, the over-exaggerated race condition no longer resulted in an invalid app state.

Summary:
On an iPhone running iOS 10.3.3, I'm not seeing the UIContentSizeCategoryDidChangeNotification fire when changing the system's font scale setting. Registering for the event on `nil` instead of on the application object fixes the issue.
**Test Plan**
Verified that text in an RN app changes size when you change the system's font scale setting (Settings -> General -> Accessibility -> Larger Text). By default, RN text is supposed to scale with the system setting.

Summary:
This commit enables state WebViewState before triggering reload on WebView. This will (if defined) trigger the loading screen again.
On iOS the LoadingIndicator will be called whenever you reload the WebView. On Android this feature is missing (see #11013). This PR adds this behaviour.
Important: One might think that "onLoadStart" is the right area to add this code, but on Android onLoadStart will also trigger for sub-resources -> the loading screen will also appear when loading iframes on the same page. I expect thats why this was not added in first place.

Summary:
**Motivation**
On Apple TV, pressing the menu button destroys the native view that backs the `Modal` component, causing an app using this component to get into a broken state. This fix implements `onRequestClose` for tvOS to have the same behavior as it does for the Android back button.
**Test plan**
Manually tested this with the `ModalExample` in the `RNTester` app. See also the test code in issue #15313.

Summary:
We sometimes get large PRs that sit for a long time without being reviewed. In some cases, the PR touches too many files or lines, and the author would benefit from splitting the PR into smaller easier-to-review PRs. In this PR, we automatically flag such PRs using the existing Danger PR automation functionality.
This PR achieves the objective by doing the following:
* Add facebook-open-source-bot to `IssueCommands.txt`, allowing it to add labels and close issues/PRs via facebook-github-bot commands.
* Adds a `large-pr` command to facebook-github-bot. This command will add a short blurb, apply a new "Large PR" label, and close the PR.
* Updates the Dangerfile to check for PRs that touch over 600 lines and/or files. In such cases it will warn and then issue the large-pr command.
Additional changes:
* Tag core contributor PRs with the "Core Team" label. This is a slight change in policy, in that the label used to be applied after the fact (after the PR was escalated for review). It's more convenient to monitor labels, so we'll start checking for PRs tagged as such and ensure they get escalated as needed. cc skevy

The section on changing ports is missing a key step for folks wishing to run on device
What existing problem does the pull request solve?
Changing packager port to something other than 8081 also requires the react native xcode project file to be updated in order to be able to build and run on device. The section on changing ports currently does not address this. See https://github.com/facebook/react-native/issues/10715#issuecomment-258082512.
Documentation update, no tests required.
A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website. See [What is a Test Plan?][1] to learn more.
If you have added code that should be tested, add tests.
Sign the [CLA][2], if you haven't already.
Small pull requests are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it.
Make sure all **tests pass** on both [Travis][3] and [Circle CI][4]. PRs that break tests are unlikely to be merged.

Summary:
This is a workaround for missing PDF url support in Android WebView, which is a general known issue: when tapping a PDF url within WebView, instead of doing nothing, we just let android default intent handle it (e.g. it will open Chrome to load it).
This is basically to trick `shouldOverrideUrlLoading()` to return true for the specific url. The drawback is that product code needs to provide the whitelist.
The proper fix would be to use PdfRenderer in that method, but it seems like it's only for API >= 21...

Summary:
Since the `hot` parameter is not used anymore in metro-bundler (we are always applying the HMR transforms for bundlers requested through the HTTP server), we can remove it from the client request URL.
This allows us to reduce the metro-bundler memory by half when switching between HMR and not-HMR, since metro caches the bundles based on the requested URL path.

Summary:
(This diff was decoupled from D4983054 which landing was quite delayed.)
`RCTUnsafeExecuteOnMainQueueOnceSync()` synchronously executes a block once, on main queue.
I found that our old implementation of `RCTScreenScale()` causes deadlock when it is called from main and background thread simultaneously.
After I implemented my own solution I googled this issue and found an article by Ben Alpert with this awesome helper:
https://benalpert.com/2014/04/02/dispatch-once-initialization-on-the-main-thread.html
So, I found it super useful and borrowed it.

Summary:
We ran into a couple of problems with the implementation of `getCurrentPosition` on Android:
- It sometimes returns an inaccurate location
- It times out when `enableHighAccuracy` is `true` (#7495)
This change improves `getCurrentPosition` for both of the above problems. Instead of calling `requestSingleUpdate` it now calls `requestLocationUpdates` so it can receive multiple locations giving it an opportunity to pick a better one. Unlike `requestSingleUpdate`, this approach doesn't seem to timeout when `enableHighAccuracy` is `true`.
**Test plan (required)**
Verified in a test app that `getCurrentPosition` returns a good location and doesn't timeout when `enableHighAccuracy` is `true`. Also, my team has been using this change in our app in production.
