Subject: [PATCH 003/273] Ignore DevDependencies when generating template.
 (#20542)

Summary:
Regarding [Add devDependenices support for templates](https://github.com/facebook/react-native/commit/c4ab03a18e75e6ed55444b5d86f3ceee435b9a78).

Once a project is created using the custom template command with devDependencies inside, the devDependenices.json file is also copied to the new projects directory.

By adding this to the ignore paths we stop the devDependenices being copied into the new projects directory.

Subject: [PATCH 004/273] Add support for linking scoped packages (#18766)
 (#19828)

Summary:
Currently, when the cli tries to determine the package name, it accidentally trims out the entire package name.  This makes it appear to the rest of the program as if `react-native link The controller you requested could not be found./my-package` was just `react-native link`.  This adds a little regex to prevent that from happening, so that scopes can be passed as parts of packages.

Fixes #18766

Subject: [PATCH 006/273] Un-deprecate TextInput.State.focusTextInput and
 TextInput.State.blurTextInput (#20326)

Summary:
In https://github.com/facebook/react-native/pull/18936 we decided to deprecate `focusTextInput` and `blurTextInput` but since then I found a valid use case for it that is pretty much impossible to implement otherwise.

React Navigation uses it to blur / re-focus the input during the swipe back gesture. Blur can be done with Keyboard.dismiss but without this api we cannot re-focus the text field that was focused if the swipe back gesture is cancelled. See https://github.com/react-navigation/react-navigation/blob/master/src/navigators/createKeyboardAwareNavigator.js#L21-L34

I think it is best to just bring back this api.

Subject: [PATCH 008/273] Update template to Xcode 9.4 and fix project settings
 warnings (#19626)

Summary:
Motivation: Fix Xcode Project Settings Warnings
![screenshot 2018-06-08 10 58 23](https://user-images.githubusercontent.com/5353594/41173274-1a4fbb3e-6b0b-11e8-973b-8290794a4f8b.png)

Should still build and pass all tests since project settings changes should be safe changes.

No documentation change is required

Subject: [PATCH 011/273] added accessibilityHints implementation on Android

Summary:
Implemented a version of accessibility Hints on android by adding hint text to the end of contentDescription. There is already an existing prop on js and iOS implementation.

Changes involve:
* adding a prop on native android code for accessibilityHints
* setting the accessibilityDelegate after the props are all loaded.
* Instead of directly updating the accessibility delegate, the prop setters now update state by setting the values of the variables. Once all props are set, the accessibility delegate is set based on the props
   * BaseViewManager keeps track of whether or not accessibility props have been set
   * AccessibilityDelegateUtil keeps track of what the props have been set to. (Renamed AccessibilityRoleUtil to AccessibilityDelegateUtil)

Currently, this is the easiest way of emulating the way accessibility hints work on iOS, and I think having an android counter part is better than having nothing.

It's different from iOS in that it will announce the hint before the role, and also cannot be turned off.

Ex:

if I set the accessibility like this:
```
      <View
        style={styles.container}
        accessible={true}
        accessibilityLabel="accessibility label"
        accessibilityRole="button"
        accessibilityStates={['selected']}
        accessibilityHint="accessibility Hint">
        <Text> Tester </Text>
      </View>
```

Talk back will read:
`accessibility label, accessibility Hint, button, selected`

In the future for next steps, I plan on investigating the process of making a second announcement after the first

Summary:
Some time ago I had to add a monkeypatch to the `http` library to enforce IPv6, due to the lack of support in Node for that. In version 2.2.0 of `node-fecth`, this has been fixed, and `family: 6` can be enforced via `agent`, which is what this diff does.

I also simplified `Promise` handling at the `test-console-call` level by removing an un-needed `.then()` nesting.

Subject: [PATCH 015/273] Replace '@flow strict(-local)' with '@flow' in
 .android.js files

Summary:
Flow doesn't check .android.js files yet anyway.

I'm going to be adding suppressions in a followup diff. It would be nice to not have >1k suppressions saying that we can't do certain things in `flow strict` when we don't even typecheck with regular `flow` just yet

I ran these commands to produce this diff:
`find . -name '*.android.js' -exec sed -i 's/flow strict-local/flow/g' {} +`
`find . -name '*.android.js' -exec sed -i 's/flow strict/flow/g' {} +`

Followed https://unix.stackexchange.com/questions/112023/how-can-i-replace-a-string-in-a-files to do it.

The controller you requested could not be found.

Subject: [PATCH 018/273] Explicitly make UIManagerModule use OnBatchComplete
 on Android

Summary:
Currently, we scan all native modules to see if they implement the OnBatchCompleteListerner. If they do, we add those modules to a list, and when C++ calls OnBactchComplete is called, we execute the callback on each of the modules.
The only native module implementing this callback today is the UIManagerModule. With Fabric, UIManager will also not be a native module anymore. This diff removes all the work done for creating the list and assumes that UIManagerModule is the only place that is interested in OnBatchComplete call - and calls it directly.

Subject: [PATCH 020/273] fix gradle wrapper issue (#19976)

Summary:
Just change gradle.properties version number to change gradle version is not the right way. Because sometimes the gradlew and gradlew.bat or even the jar need to be updated too.
I also add the wrapper task to `build.gradle`, so next time, we just need to change the version number and execute `gradlew wrapper`.
pass all current ci.

Subject: [PATCH 021/273] Move Switch native require call to new file

Summary: Moving out the requireNativeComponent call into a new file. We want this long term for all of our view managers to support codegen of the native side and so we can move the viewConfigs into JS.

Subject: [PATCH 023/273] Check return code from malloc (#20173)

Summary:
Calls abort() in cases where malloc returns NULL.

Checking the return value from malloc is good practice and is
required to pass a [Veracode security scan](https://www.veracode.com/). This will let
developers who are required to submit their software to Veracode
use React Native.

Subject: [PATCH 024/273] Exposed scrollEnabled on TextInput (#19330)

Summary:
On iOS, it is not possible to select a range of text using a `Text` component (see #13938). Because of how the `Text` component is implemented on iOS, this will not work without a complete re-write. On Android however, this is not an issue.

As the `TextInput` component has evolved, it can more or less be used as a drop-in replacement on iOS by setting `multiline={true}` and `editable={false}`. Except for one detail: the text input field has scrolling activated and it's not possible to turn off. (See #1391 and #15962).

This pull request addresses that issue, simply by exposing the `scrollEnabled` property:

```
<TextInput
    multiline
    editable={false}
    scrollEnabled={false}
  />
```

1. Create a multiline `TextInput` component, with the attributes presented above.
2. Run on iOS
3. The `TextInput` field should not be able to scroll

Subject: [PATCH 025/273] Move View native require call to new file

Summary: Moving out the requireNativeComponent call into a new file. We want this long term for all of our view managers to support codegen of the native side and so we can move the viewConfigs into JS.

Subject: [PATCH 029/273] Properly escape JavaScript code on Android (#20366)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
These changes will fix executing javascript with any special characters, by making use of the `evaluateJavascript` function on Android 4.4+, and by properly escaping the URI on Android <4.4.

Fixes #19611 • Fixes #20365 • Fixes #9749 • Closes #19655 • Closes #12321

This PR supersedes #19655 by patching the same problem in all the places, and fixing it for Android <4.4 as well.
Pull Request resolved: https://github.com/facebook/react-native/pull/20366

Subject: [PATCH 030/273] iOS: prevent nativemodule access from JS if bridge is
 no longer valid

Summary: This helps prevent race condition where JS calls to NativeModules got queued and executed while the bridge is invalidating itself, causing assertion failures in test setup (for example). It won't prevent it 100% of the time, due to threading (and adding lock is expensive for each nativemodule call).

Subject: [PATCH 032/273] Check Flow and run basic packager tests using open
 source RN config

Summary:
Most of the changes associated with this commit will not be visible on GitHub, as they concern files in the internal Facebook monorepo. The bulk of this change is the addition of a new test that runs on the internal test infrastructure. The actual script used by the test has various references to the internal test infra, but a copy is produced below with some changes that should allow it to run on open source should anyone be interested in testing this outside of Facebook.

The test has the main goal of catching common sources of FB-to-GitHub breakages, such as the OSS Flow config falling out of date (we use a different flow config than what is synced out in .flowconfig, and hence internally we rename this file to .github.flowconfig). It also checks that the packager can run on a brand new project, among other things.

Subject: [PATCH 033/273] Upgrade Babel to 7.0.0-beta.56 (#216)

Summary:
**Summary**

This pull request bumps Babel to 7.0.0-beta.56 to incorporate the latest bugfixes from Babel.

**Test plan**

One way to test is to add a simple TypeScript file with a type as the default export:

```typescript
export const test = 1
export default interface A {}
```

and then import that file from any other file:

```js
import { test } from './typescript-test'
```

Before this would throw an error, but with the latest Babel this is now fixed.

Subject: [PATCH 037/273] Disable failing tests (#20622)

Summary:
`test_detox_end_to_end` and `test_objc_end_to_end` are both failing on master. This is polluting internal diffs that do not introduce failures.

As we just now started tracking Circle CI on our internal builds, I want to make sure we only nag internal diffs when the failure can actually be attributed to the diff. The failures in the e2e tests precede the Circle CI integration and are adding unnecessary noise.

Going forward, we will immediately go back to a diff and push the author to fix the broken CI, so this PR is a temporary fix.

Subject: [PATCH 040/273] Ensure WebViews render about:blank correctly

Summary:
@public

This diff fixes two bugs:
1. When you load a `<WebView/>` with an HTML source string, HTML source doesn't render in the `<WebView/>`. Instead, we get this warning: https://pxl.cl/grz3. Here's what the above page should look like when correctly rendered: https://pxl.cl/grzt

2. Furthermore, you render a blank `<WebView/>` (i.e: with no source prop), it should display a blank page. Instead, we get this warning: https://pxl.cl/grz3

**Bugfix:**
One solution I found was to ensure that `about:blank` is always whitelisted. That way, we don't ever abort navigations to blank pages, which occur when we do:

```ObjectiveC
/** Line 134 in RCTWebView.m */
[_webView loadHTMLString:@"" baseURL:nil];
```

and

```ObjectiveC
/** Line 115 in RCTWebView.m */
if (html) {
  NSURL *baseURL = [RCTConvert NSURL:source[@"baseUrl"]];
  if (!baseURL) {
    baseURL = [NSURL URLWithString:@"about:blank"];
  }
  [_webView loadHTMLString:html baseURL:baseURL];
  return;
}
```

Subject: [PATCH 041/273] Fix native animated style and transform node to call
 __makeNative once all the children are converted to native nodes (#20658)

Summary:
This PR fixes an issue I have found while playing with native animated driver nodes.

I discovered the bug when using animated views that have both animated props and styles. See this snack to see an example: https://snack.expo.io/B17SFXy8Q

In that example we set `opacity` and `style` props which both contain animated props. This is not an usual way to do that, as normally you would place `opacity` inside the `styles` in which case the bug won't surface. But this is only done for demo purposes and in practice the problem will occur if you have a custom native view that exposes props that are not styles and can be animated.

In the above example you get this error:

> Invariant Violation: Attempt to get native tag from node not marked as "native"

When `opacity` is moved into `styles` container the problem no longer occurs.

The problem turned out to be related to the initialization code responsible for creating native animated nodes. In all subclasses of `AnimatedWithChildren` (like `AimatedAddition`) we only call `super.__makeNative` after we call `__makeNative` method on the child nodes. This order was reversed in `AnimatedStyle` and `AnimatedTransform`. As a result when `super.__makeNative` is called in `AnimatedStyle`, we try to call `__getNativeTag` on children nodes not yet marked as native which results in the error described above ("Attempt to get native tag...").

We should instead follow the order of calling `super.__makeNative` that is used in the remaining subclasses of `AnimatedWithChildren`. Such that all the children nodes are first converted to native prior to calling superclass method. This is what this PR is changing.

Summary:
.android.js files may be checked (when the next version of flow is released) by using `flow start --flowconfig-name .flowconfig.android` and `flow status --flowconfig-name .flowconfig.android`

This diff adds suppressions to the errors that are in .android.js files, which flow does not check right now.

When site is `react_native_fb` or `react_native_android_fb`, error will be suppressed when checking with .flowconfig.android
When site is `react_native_fb` or `react_native_ios_fb`, error will be suppressed when checking with .flowconfig.

You can use `react_native_fb` when it should be suppressed for both.

The controller you requested could not be found.

Subject: [PATCH 045/273] Correctly find rootView when RCTTouchHandler is in a
 RCTSurface

Summary:
@public
I'm surprised this hasn't caused an issue earlier.
RCTTouchHandler is hooked up to RCTSurfaceView which itself contains a rootView. Thus when this calculation happens, a root view is never found.
We can't assign to the root view since it created and destroyed frequently, so it makes the most sense to look for the RCTSurfaceView here and treat it as a root view.

Summary: Fixes the `Touchable` debug view. The `child.type` is no longer a subclass of `React.Component` and no longer has `displayName`. It should be fine to have a hard dependency on `Text` and `View`, because... what app does not use them?

Subject: [PATCH 051/273] Do not override `metro.config.js` settings (#20705)

Summary:
React Native overrides the `metro.config.js` settings for, e.g., `hasteImplModulePath`, which prevents us from adding a `metro.config.js` file to the repo for `react-native-windows` to allow us to resolve Haste modules at the top-level of the repo. This change ensures that if a user has a `metro.config.js` file, those settings are not overwritten by React Native.

Subject: [PATCH 054/273] Implement WKWebView to replace WebView

Summary:
@public

`UIWebView` has been deprecated and replaced by `WKWebView`. This diff introduces a new component `WKWebView` that simply renders a `WKWebView` on iOS.

This is the first in the stack of many diffs that'll be required to fully replace `UIWebView` with `WKWebView` in the `<WebView/>` React Native component. Eventually, I hope to introduce a prop called `useWebKitImplementation`, which, when true, will force RN to use `WKWebView` instead of `UIWebView` for the `<WebView/>` component.

The only thing that's been implemented so far is the `source` property.

Subject: [PATCH 055/273] Implement onLoading(Start|Finish|Error) and
 injectedJavaScript props

Summary:
@public

This diff includes four very straightforward changes:
1. Whenever the WebView starts loading, the `onLoadingStart` hook should be executed. The event passed into this hook should be decorated with the `navigationType`.
1. Whenever the WebView errors out while loading, the `onLoadingError` hook should be executed.
1. Whenever the WebView finishes loading (without any errors), the `onLoadingFinish` hook should be executed.
1. The serialized JavaScript passed into the `injectedJavaScript` prop should be executed when the WebView finishes loading. After execution finishes, the `onLoadingFinish` prop should be called with the serialized completion value of this JavaScript.

Subject: [PATCH 056/273] Implement message passing!

Summary:
@public

This diff implements message passing between the `WKWebView` and React Native. As with `<WebView/>`, we can only send/receive strings.

**Usage:**
1. Set `messagingEnabled` to `true`.
1. To send data from the web view to React Native, call `postMessage(data)` within the web view. This forces React Native to execute the `onMessage` prop on the `WKWebView` component. `onMessage` will be called with an event `e`, where `e.nativeEvent.data` will be the data you passed into `postMessage`.
1. To send data from React Native to the web view, call `UIManager.dispatchViewManagerCommand` to dispatch the `UIManager.RCTWKWebView.Commands.postMessage` command. Look at [[ https://fburl.com/u1wusf2f | this part of the existing `<WebView/>` ]] component for more details. After you make the call, React Native will dispatch a `'message'` event to the `document` object within the webview. You can listen to the event by doing `document.addEventListener('message', callback)`. Let the event dispatched be `e`. Then, `e.data` is the data you sent over from React Native.

[[ P58627181 | This Playground.js ]] illustrates the usage.

Subject: [PATCH 057/273] Implement 'bounces' prop

Summary:
@public

The content that loads inside `WKWebView` renders within a `ScrollView`. Suppose the user pulls the page down when its top edge hits the top edge of the web view. Then, one of two things can happen as the user continues to pull the page down:
1. We let the page be pulled past the top edge of the web view.
1. We fix the page's vertical offset to 0 so that it doesn't move past the top edge of the web view.

The property that controls this behaviour is `<WKWebView bounces={true|false}/>`. In this diff, I implement it.

Subject: [PATCH 059/273] Implement 'decelerationRate' prop

Summary:
@public

The content that renders within the `WKWebView` instance actually renders inside a `UIScrollView`. On that scroll view, we can adjust the `decelerationRate`, which controls how fast the view stops scrolling after the user lets go while scrolling.

In this diff, I implemented the `decelerationRate` prop for `WKWebView`, which gets forwarded to the `UIScrollView` instance underlying the web view.

**Note:** Even though we accept a floating point value for the deceleration rate, the native `UIScrollView` component only allows two inputs:
1. `UIScrollViewDecelerationRateNormal`: 0.998
2. `UIScrollViewDecelerationRateFast`: 0.99

As far as I know, it seems to just round up to the nearest valid `CGFloat` (or down if number > 0.998), for any invalid numbers.

Subject: [PATCH 063/273] Implement 'onShouldStartLoadWithRequest' prop

Summary:
@public

This diff introduces the native backend for a new WKWebView prop: `onShouldStartLoadWithRequest`.

In the final component, the behaviour will be as follows: Whenever the user navigates around in the web view, we call `onShouldStartLoadWithRequest` with the navigation event. If `onShouldStartLoadWithRequest` returns `true`, we continue the navigation. Otherwise, we abort it.

Subject: [PATCH 064/273] Implement 'allowsInlineMediaPlayback` prop

Summary:
For iPhones with small screen sizes (e.g: iPhone 5s), inside the `<WKWebView/>` component, videos will play in fullscreen mode. In this diff, I introduce a prop called `allowsInlineMediaPlayback` that when set to true, will allow videos to play inline.

**Note:** For videos to play inline, the HTML video element must also have a `playsinline` attribute on it.

Subject: [PATCH 066/273] Implement 'dataDetectorTypes' prop

Summary:
When text is rendered in `WKWebView` WebKit component, the component itself can detect things like phone numbers, flight numbers, links, etc. and render them with additional functionality.

For example, when the text `apple.com` is detected, if the `link` data detector type is enabled, the web view will actually render a link that takes the user to the Apple home page.

In this diff, I implement the `dataDetectorTypes` prop. The data detector types supported are:
1. phoneNumber
1. link
1. address
1. calendarEvent
1. trackingNumber
1. flightNumber
1. lookupSuggestion

These enums are documented in the [[ https://developer.apple.com/documentation/webkit/wkdatadetectortypes | WKDataDetectorTypes docs ]].

Subject: [PATCH 067/273] Implement 'backgroundColor' style

Summary:
@public

This diff implements background colors for the `RCTWKWebView` component by proxying the background color prop to the underlying `WKWebView` and its underlying `UIScrollView`.

There's few differences between `backgroundColor` in `RCTWebView` and `RCTWKWebView` implementations:
1. With `UIWebView,` the background color gets applied after the page loads. With `WKWebView`, this isn't necessarily true. This results in a white flicker on solid backgrounds because sometimes, the background color is set before the page loads. This video illustrates the problem: https://our.intern.facebook.com/intern/px/p/9QBH
1. As far as I can tell, `WKWebView` doesn't handle transparent backgrounds correctly. Either that, or I could be setting the background color incorrectly. I set the background color to `rgba(1, 1, 1, 0.5)` and recorded how both `RCTWebView` and `RCTWKWebView` render. These two videos indicate the differences:
**RCTWebView: Lighter background**
https://pxl.cl/9R13
**RCTWKWebView: Darker background**
https://pxl.cl/9R1b

I tried to replicate this on the web. According to [[ https://our.intern.facebook.com/intern/fiddle/zCHu/ | this fiddle ]], `RCTWebView` is correct. Clearly, RCTWKWebView is rendering transparent backgrounds a bit darker than necessary. This doesn't seem simple to debug, so I've created a task to document this work: T23815343. I'll get to it eventually.

Subject: [PATCH 068/273] Implement 'automaticallyAdjustContentInsets' and
 'contentInset' props

Summary:
@public

This diff introduces two new props:
1. **automaticallyAdjustContentInsets**: Controls whether to adjust the content inset for web views that are placed behind a navigation bar, tab bar, or toolbar. The default value is true.
1. **contentInset**: The amount by which the web view content is inset from the edges of the scroll view. Defaults to {top: 0, left: 0, bottom: 0, right: 0}.

**Note:** There're some inconsistencies between how `UIWebView` and `WKWebView` render web pages with respect to the `contentInset` property. These two videos illustrate the problem:

**UIWebView**
[[ P58674349 | Playground.js ]]
https://pxl.cl/9R9V

**WKWebView**
[[ P58674348 | Playground.js ]]
https://pxl.cl/9R9W

Here's a stack overflow answer describing the problem: https://stackoverflow.com/a/35472603.

Subject: [PATCH 070/273] Warn when 'scalesPageToFit' prop is used

Summary:
@public

The `WKWebView` class doesn't expose a `scalesPageToFit` property, unlike `UIWebView`. Therefore, the `scalesPageToFit` RN prop is be a bit tricky to implement with `WKWebView`.

For the time being, this diff adds warnings to `<WebView/>` whenever `useWebKit={true}` and `scalesPageToFit` is set. I've also updated the documentation to reflect that we don't support `scalesPageToFit` prop with the new implementation of `<WebView/>`.

Subject: [PATCH 071/273] Dynamically load WebKit

Summary:
@public

We can't dynamically link `WebKit` because doing so will impact cold start of all our Apps.

This diff includes a few changes:
 1. Weakly link the `WebKit` framework in the `ReactInternal` library, so that the compiler doesn't die when it encounters a WebKit symbol.
 2. Undo dynamic linking of WebKit in Catalyst.
 3. Undo dynamic linking of WebKit in AdsManager
 4. Before the first `WKWebView` is instantiated, dynamically load the `WebKit` framework.

The end result of these changes is that WebKit will be loaded only when it's going to be used.

Subject: [PATCH 075/273] ignore babelrc in git-upgrade (#20790)

Summary:
Per [this comment on the issue](https://github.com/facebook/react-native/issues/20710#issuecomment-414631827):

> Babel by default tries to find .babelrc files to configure itself, and once it finds the one from the RN app (which links to the RN preset that only works on Babel 7) it fails.
> The easiest patch to fix this issue is to add babelrc: false to the babel-register method, so Babel does not read any additional .babelrc file.

Fixes #20710

Summary:
Commit 79e498b7fbf19ab50bb73697602910fb827ff928 claims that "--terminal" has been added as an argument to the "run-android" script which it hasn't. Instead it adds a new environment variable "process.env.REACT_TERMINAL" which seems to be undocumented and nowhere else in the repository.

This commit now allows Linux and OSX users to specify their custom terminal :

    react-native run-android --terminal=x-terminal-emulator

Additionally the metro bundler child process "detached" option has been set to false if no terminal has been specified on Linux which fixes an issue where the packager would be running in the background and would have to manually be closed by finding the process.

Fixes #18122

Subject: [PATCH 080/273] Run failing tests in CI, without turning CI red
 (#20775)

Summary:
We have several disabled tests in Circle, and they are not running at all.
This prevents us from seeing when a disabled test might actually be fixed, as enabling the test requires uncommenting the correct line in Circle CI's config.

In this PR, we use the existing swallow_error script to run known-failing steps, without failing the job. This will let us see the step's output in CI, without polluting PRs that have not introduced new failures to CI.

Summary:
Fixes #20769

Release notes
--------------
[CLI] [BUGFIX] [local-cli/server/checkNodeVersion.js] - Disable auto-formatting in `local-cli/server/checkNodeVersion.js` since it introduces ES6 and ES7 syntax (trailing comma in argument list) which in turn makes ES5 engines crash with a `SyntaxError`.

Subject: [PATCH 090/273] Bump compileSdkVersion to 27 and buildToolsVersion to
 27.0.3 (#20777)

Summary:
I found that android support library 27.x (https://github.com/facebook/react-native/commit/874cca1ac258ec224bade999722d7a34c307def0) requires compileSdkVersion to be 27. Also found that many FB projects use SDK 27.

Subject: [PATCH 092/273] Use one time password when publishing to npm (#20701)

Summary:
This pull request addresses the failing publish-npm.js script from earlier this week. For background, last month we reset all npm access tokens for any package related to Facebook, and we now require all accounts with publish permissions to have two factor enabled.

The publish-npm.js script relied on one such token that is configured in Circle CI as a envvar. The token has been updated in Circle CI, but we now need a way of passing the one time password to npm.

With this PR, we can now grab the otp from Circle CI's envvars. Considering otps are ephemeral, this requires the NPM_CONFIG_OTP envvar to be set by someone with publishing permissions anytime a new release will be pushed to npm. The token is short lived, but it would still be good to clear the envvar after the package is published. Circle CI envvars are not passed on to PR/forked builds.

This PR is effectively a breaking change for the release process, as the publish step will not succeed if the OTP is not valid.

OTPs are short-lived, and the publish_npm_package job will definitely outlive the token. Unfortunately this will require some timing to get right, but the alternative is to ssh into the Circle CI machine and re-run the `npm publish --otp` command, which again would still require someone with publish access to provide the otp.

Subject: [PATCH 094/273] Gate failing steps behind a username check (#20818)

Summary:
There are some steps known to be failing on master. This pollutes checks for unrelated PRs.

This PR will make it so that PRs submitted by anyone other than myself will no-op on these steps.

Future work: Have an array of whitelisted contributors, and make it much easier to turn individual tests on and off.

Subject: [PATCH 095/273] refine android config (#20731)

Summary:
By this change we can unify version early, like we can make kotlin version share in buildscript and app dependency the same time ([butterknife](https://github.com/JakeWharton/butterknife/blob/master/build.gradle) use the same).
pass all current ci and one of my project https://github.com/gengjiawen/ReactNative64bitDemo.

Subject: [PATCH 096/273] Updated the glog library version from 0.3.4 to 0.3.5
 (#20811)

Summary:
While the original reason for this change was because of an issue #20780, with further investigation I concluded that the issue is till present for this combo of versions:
glog - 0.3.5
google-cast-sdk - 4.3.1

Downgrading google-cast-sdk to 4.3.0 fixed the build issue.

Release Notes:
--------------
Updated glog version from 0.3.4 to 0.3.5 for iOS

Subject: [PATCH 097/273] Standarize options passed to the transformer

Summary:
This is the first step to make transformers fully customizable (and not be tied to JS, or RN). In order to do that, I'm changing the signature of the transformers, which currently is:

```
function transformCode(
  filename: string,
  localPath: LocalPath,
  transformerPath: string,
  options: WorkerOptions,
  assetExts: $ReadOnlyArray<string>,
  assetRegistryPath: string,
  minifierPath: string,
  asyncRequireModulePath: string,
  dynamicDepsInPackages: DynamicRequiresBehavior,
)
```

to be:

```
async function transformCode(
  filename: string,
  localPath: LocalPath,
  options: WorkerOptions,
)
```

(so basically, all the RN-custom properties are moved to `WorkerOptions`, which in the future will be a generic to allow anybody pass any random option to their transformers).

In order to make all this work, I've had to get rid of the logic that calculates the base cache key hash based on a subset of worker options (the ones that Metro knows that are not going to change between runs).

This could potentially cause a perf regression (since we're now making the hash calculation a bit more costly), and in fact I could measure a ~400ms regression on the worse case scenario (which happens when restarting Metro and re-transforming a Wilde from a warm local cache).

I've benchmarked this regression and could find that it's caused by the array of `assetExtensions` (which is potentially large). I have a followup diff to improve this, which is able to remove the regression completely.

Subject: [PATCH 098/273] Expose the actual transformer in the config

Summary:
This diff exposes the new more generic way to configure transformers in `Metro` via the config parameter `transformerPath`.

The new generic transformers can be used to transform any kind of file, since they don't call any JS-specific method and their API is generic. They only need to implement a single `transform` method:

```
async function transform(
  absolutePath: string,
  relativePath: string,
  fileContents: Buffer,
  options: TransformOptions, // very soon these will be configurable
): Promise<{
  output: Array<mixed>,
  dependencies: Array<{
    name: string,
    data: mixed, // very soon
  }>,
}> {
  // ...
}
```

Metro already had a `transformModulePath` config param, which was used to configure how babel was called in order to generate the AST. In order to avoid confusion, but keep the current open source transformer worker, I've renamed this param to `babelTransformerPath`. We can add a layer of compatibility and detect old config params in order to show a deprecation warning.

Subject: [PATCH 102/273] Expose the actual transformer in the config

Summary:
This diff exposes the new more generic way to configure transformers in `Metro` via the config parameter `transformerPath`.

The new generic transformers can be used to transform any kind of file, since they don't call any JS-specific method and their API is generic. They only need to implement a single `transform` method:

```
async function transform(
  absolutePath: string,
  relativePath: string,
  fileContents: Buffer,
  options: TransformOptions, // very soon these will be configurable
): Promise<{
  output: Array<mixed>,
  dependencies: Array<{
    name: string,
    data: mixed, // very soon
  }>,
}> {
  // ...
}
```

Metro already had a `transformModulePath` config param, which was used to configure how babel was called in order to generate the AST. In order to avoid confusion, but keep the current open source transformer worker, I've renamed this param to `babelTransformerPath`. We can add a layer of compatibility and detect old config params in order to show a deprecation warning.

Subject: [PATCH 104/273] Make the --transformer CLI argument override the
 babelTransformerPath

Summary: D9070810 introduced a breaking change, making the `--transformer` CLI argument able to override the generic transformer instead of `babelTransformer`. Since we still have some scripts that assume `--transformer` is being used for overriding the babelTransformer path, we cannot do this breaking change yet, so this diff reverts the CLI handling to the old behaviour.

Subject: [PATCH 108/273] Add support for out-of-tree platform plugins (#20825)

Summary:
This pull request adds the ability for a platform developer to provide a `"haste"` key under the `"rnpm"` key in their `package.json` which allows the packager to pick up that platform's javascript files. The intent is to remove the need to have custom platforms hardcoded in. This is inspired by the `"jest": { "haste": {} }` key used by jest.

For example, React Native Dom would have an entry like:

```json
{
  "rnpm": {
    "haste": {
      "providesModuleNodeModules": [
        "react-native-dom"
      ],
      "platforms": [
        "dom"
      ]
    }
  }
}
```

Support for more keys (path blacklists perhaps?) could be added in the future.

This succeeds #20662, as per a discussion I had with matthargett.

I've got an open discussion over here as well: https://github.com/react-native-community/discussions-and-proposals/issues/21
Pull Request resolved: https://github.com/facebook/react-native/pull/20825

Subject: [PATCH 109/273] iOS downgrade error to warning when invoking native
 module with invalid bridge

Summary: A bunch of flows including JS reload and e2e tests seem to hit the race condition, causing redbox. For now, make it a warning to unblock.

Subject: [PATCH 110/273] ScrollView snapToOffsets

Summary:
* Added snapToOffsets prop to ScrollView. Allows snapping at arbitrary points.

* Fixed pagingEnabled not being overridden by snapToInterval on iOS.

* Fixed Android *requiring* pagingEnabled to be defined alongside snapToInterval.
* Added support for decelerationRate on Android.

* Fixed snapping implementation. It was not calculating end position correctly at all (velocity is not a linear offset).
  * Resolves https://github.com/facebook/react-native/issues/20155
* Added support for new content being added during scroll (mirrors existing functionality in vertical ScrollView).

* Added support for snapToInterval.
  * Resolves https://github.com/facebook/react-native/issues/19552

Subject: [PATCH 124/273] Adding a more complete type for
 ReactNativeBaseComponentViewConfig

Summary:
As we add js view configs to our view managers, we want this type to be a little bit more strict.

This will be especially useful as we start removing certain keys (like NativeProps) which aren't actually necessary, this will make sure we remove them everywhere.

Subject: [PATCH 129/273] Fix #18272 TextInput.setNativeProps({text: ''}) to
 work (#18278)

Summary:
Fix #18272. Calling textInputRef.setNativeProps({text: ''}) or textInputRef.clear() should clear the text input.

- All tests of `yarn run test` are passed
- Test with [the sample app](https://github.com/magicien/react-native-textinput-clear).
    - TextInput.clear() and TextInput.setNativeProps({ text: '***' }) worked
    - When clear() or setNativeProps() called, onChange/onChangeText wasn't called
        - Same behavior as react 0.53.0
    - When non-string values are given to `setNativeProps({text: ___})`, its behavior is the same as react 0.53.0.
        - Value Type | Result
          ---------- | ------------
          null       | same as empty string ''
          undefined  | nothing changes
          number     | throw error
          function   | throw error
          object     | throw error
    - When clear() or setNativeProps() called, attributed text keeps the attributes
    - When `value` prop is set, the text can't be changed

- `clear()` doesn't work from the second time
- `setNativeProps({text '***'})` doesn't work from the second time
- Even when `value` prop is set, you can change the text

![ScreenShot_0.54.0](https://raw.githubusercontent.com/magicien/react-native-textinput-clear/master/screenshot/0.54.0_test.gif)

- `clear()` works every time
- `setNativeProps({text '****'})` works every time

![ScreenShot_Clear_1](https://raw.githubusercontent.com/magicien/react-native-textinput-clear/master/screenshot/clear_test_1.gif)

![ScreenShot_Clear_2](https://raw.githubusercontent.com/magicien/react-native-textinput-clear/master/screenshot/clear_test_2.gif)

- The text keeps the attributes (font family, size, color, text align)

![ScreenShot_Slider](https://raw.githubusercontent.com/magicien/react-native-textinput-clear/master/screenshot/attributed_text_test.gif)

- If `value` prop is set, the text should not be changed

Subject: [PATCH 130/273] Add the new RCTWKWebView* files to build target on
 iOS (#21031)

Summary:
These files support backing a `WebView` component with the WebKit-based
`WKWebView` on iOS.  These files need to be included in the Xcode
build target so that they are compiled, linked and ultimately available
to the UIManager at runtime, so that the correct views can be instantiated
when a `WebView` is passed the prop `useWebKit={true}`.

Summary:
Fixing error

When integrating with cocoa pods
```
pod 'React', :path => './node_modules/react-native', :subspecs => [
    'Core',
    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',

    'RCTWebSocket',
    'BatchedBridge',
    'RCTLinkingIOS',
    'RCTActionSheet',
    'RCTAnimation'
    ]
```
With `RCTAnimation` being the important part for this PR.

Also note without this PR and the other PR's above if anyone is trying to integrate react native into an existing app i.e. through cocoa pods they won't be able too. I think the latest working version is

My app wouldn't build without changing this line

Subject: [PATCH 134/273] Remove view configs from JS

Subject: [PATCH 138/273] Give RNPM the ability to look for plugins in
 `@scoped` modules (#21082)

Summary:
This PR gives RNPM the ability to look for plugins in `scoped` modules.

The regexes for finding RNPM plugins will match these hypothetical examples:

 * `rnpm-plugin-foo`
 * `org/rnpm-plugin-foo`

The regexes for finding React Native plugins will match these hypothetical examples:

 * `react-native-foo`
 * `org/react-native-foo`
 * `The controller you requested could not be found./module` (will be useful in the slimmening)
 * `The controller you requested could not be found./module`

RNPM plugins will be able to benefit from this immediately, but React Native plugins will run into this Metro issue currently:

Subject: [PATCH 142/273] Fix ignored --projectRoot/watchFolders arguments
 (#21165)

Summary:
Due to Kureev's cleanup in https://github.com/facebook/react-native/commit/c4a66a89a28152cd4b81e2b0f80ab3aac34d6872 some arguments are no longer properly passed to metro, but just the default values. This broke the `--projectRoot` and `--watchFolders` arguments used by storybook to change the bundle entrypoint.

This PR simply fixes the regression by assigning these values from argv instead of reading config defaults.

Related: the undocumented `REACT_NATIVE_APP_ROOT` env var is broken, not sure for how long, but I can fix it as a part of this PR or make a new one.

Subject: [PATCH 144/273] Way to register RCT_MODULE in Plugin2.0 instead of
 +load

Summary:
[RFC] WIP: Way to register RCT_MODULE in Plugin2.0 instead of +load

This seemed like the simplest way to do this to register in the existing
didNotFindModule callback so that we don't have to touch any opensource code.

NOTE: The new version of this fixes the problems with dylibs, but not the -ObjC flag removal. This seems like the right call to avoid users having to implement c-functions to return their classes; instead we used objc_getClass.

Subject: [PATCH 153/273] Remove global babelHelpers and regenerator (#21283)

Summary:
Follow up to https://github.com/facebook/metro/commit/8932a9caa8f9ffe82160f2da25342a0bde3bbb26

Babel helpers and regenerator runtime will be imported automatically from `babel/runtime`. We still need to add the global regeneratorRuntime for jest tests since we disable babel-runtime currently.

Subject: [PATCH 155/273] Android ScrollView support for `overflow: visible`

Summary:
ScrollView always clipping children on Android even when `overflow: visible` was specified.
This change just omits the clipping during draw if `overflow: visible` is passed in.
The default is not changed (from hidden to visible) in case there is a performance impact.
Android now matches iOS in behavior. This helps with issue #21116 and resolves #14416.

Summary:
Support for `overflow: visible` was recently added to Android ScrollView.
However, it didn't account for `overflow: scroll` and changed the behavior, causing content to render
when before it would be clipped.

Summary:
Fixes #18223

This is a fairly simple solution to what seems to be a recurring issue where certain requests that result in an empty body where JSON is expected throw an error rather than being handled gracefully. Client side error handling is not being hit as this is being thrown at a lower level.
Make a http request that results in an empty blob: ""

Subject: [PATCH 159/273] Remove absolute path parameter from transformers

Summary:
Up until now, transformers in Metro received the absolute path of a file, the relative path of a file and the projectRoot.

This diff gets rid of the absolute path sent to the worker, since by having the projectRoot and the relative path, the absolute path can be easily calculated.

This has been done to avoid having absolute paths as transform options, since we need to have custom logic to filter them out from the cache key generation, which is dangerous.

Summary:
<!--
  Required: Write your motivation here.
  If this PR fixes an issue, type "Fixes #issueNumber" to automatically close the issue when the PR is merged.
-->

Fixes inconsistency in custom font rendering in android. See explanation below.

<!--
  Required: 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 tested the following on my physical device (Sony Z5C) and on Android emulator on Mac.
The test app contains various fonts in the AvenirNext family, which are added to the app as `.ttf` format.

Note that the character "thickness" is inconsistent. Some characters looks thicker than other. See the screenshots below as an example:
- Looks thicker: right half of the `g` and `&` as in "Region & Language" (list-view screen)
- Looks thicker: `w` as in `Change Password` (list-view screen)
- Looks vertically compressed: `a` and `e` as in "Message" in the bottom bar (list-view screen)
- Looks thicker: `A`, `N`, `V`, `v` (paragraph screen)
- Looks thinner: `i` (paragraph screen), it leaves extra space on its right hand side

Every characters has consistent "weight" and looks nice:

Subject: [PATCH 162/273] Use babel runtime instead of relying on global
 babelHelpers and regenerator (#198)

Summary:
**Summary**

The RN transformer currently relies on the enviroment providing babelHelpers and regeneratorRuntime as globals by using 'babel-external-helpers'. This wasn't really a problem before since helpers were stable and we could maintain our copy easily but it seems like there are more now with babel 7 and it makes sense to include only those used by the app.

This is exactly what babel/transform-runtime does. It will alias all helpers and calls to regeneratorRuntime to files in the babel/runtime package.

This will solve issues like this https://github.com/facebook/react-native/issues/20150 caused by missing babelHelpers. This solution also avoids bloating babelHelpers to fix OSS issues like the one linked before.

**Test plan**

- Updated tests so they all pass.
- Tested that it actually works by applying the changes locally in an RN app.
- Added a test for async functions, to make sure regenerator is aliased properly and doesn't depend on the global.
- Made sure require-test.js still fails if the require implementation contains babel helpers (by adding an empty class in the file).

Subject: [PATCH 164/273] Change new Date() to Date.now() to save on date
 allocations

Summary:
`new Date().getTime()` is equal to `Date.now()`.
`Date.now()` avoids an allocation, which can save some GC time.

This micro-optimization isn't worth it in most places, but since MessageQueue is one of the hottest pieces of JS in RN, it's worth it.

On Android 5.0 and above, after the app successfully obtains the cookie, you kills the App within 30 seconds and restarts the App. It accesses the interface that needs to carry the cookie and finds that the cookie does not exist.

Updated tests for the addCookies function to include test cases specifying Android version, and tested on the command line in my app to make sure it has the expected behavior.

Subject: [PATCH 172/273] Android ScrollView fix for pagingEnabled

Summary:
The snapToOffsets changes improved the flinging algorithm for snapToInterval/snapToOffsets but actually broke it for pagingEnabled because it's meant to only scroll one page at a time.

First, I just brough back the old algorithm, but noticed that it has a bunch of issues (e.g. #20155). So, I tried to improve the algorithm to make sure it uses the proper target offset prediction using the same physics model that Android uses for it's normal scrolling but still be limited to one page scrolls.

This resolves #21116.

Subject: [PATCH 176/273] Cleanup the transformer flow types

Summary:
Since the options that are passed to the `babelTransformer` are not exactly the same ones as the `transformer` receives, we need to have a specific object for them.

This allows us to make the transformer options object strict (since unfortunately the `babeltransformer` options object comes from many places and needs a bit of work to be able to be strict...

Subject: [PATCH 186/273] Fix accessibility role/label

Summary: D10138128 had some shamefully wrong boolean logic to determine whether we should customize the accessibility delegate. Previously, we did it if BOTH the accessibility label AND role were present. We should actually do it if EITHER are present.

Subject: [PATCH 187/273] Dealloc first time RCTNetInfo reachability callback

Summary:
@public
We're seeing a crasher where `self` on line 54 isn't an `RCTNetInfo`. The timing looks related to D9798488, so my theory is that this class is being deallocated before it resolves, and thus causes a crash.

Subject: [PATCH 188/273] iOS: fix the baseline issue when displaying a mixture
 of different-language characters (#19653)

Summary:
This fixes #19193

Characters of different languages may have different height and different baseline, even with a same font and same font-size. When they mixed together, iOS will adjust their baselines automatically, to display a suitable view of text.

The problem is the behavior of dealing with the text-style property 'lineHeight'.

It once to be a right way at version 0.52.3, to setting a base-line-offset attribute for the whole range of the string. However, in current version, it enumerated the string, and set a different  base-line-offset for different font-height characters.

And this behavior broke the baseline adjustment made by the iOS. It just make every character's baseline aligned to a same line. But it is not supposed to displaying characters of different languages like that. Chinese characters' baseline is the bottom of each, however, it is not for English characters.

So maybe it is the better way to give a same value of base-line-offset attribute for the whole string. And this PR just did that: found the biggest value of font-height in the text, and calculate the offset with that biggest value, then set to the whole string. This will keep the origin baseline adjustment for different languages' chars made by iOS.

Since I always got an error when running the snapshot test locally, I can't even pass the them with the unmodified code in master branch.

The error is "Nesting of \<View\> within \<Text\> is not currently supported."

After I comment all of the check of that error from the source code, I got a different snapshot from the reference ones. It seems that all components which will cause that error are not rendered in the reference images.

Since this PR changed the behavior of 'lineHeight' property, it's better to add a new snapshot case for the situation of different-language-characters' mixture. So maybe somebody could help me with that or maybe it should be a issue?

Subject: [PATCH 191/273] When converting arguments JS->Java, handle integers
 correctly

Summary:
If a folly::dynamic contains a double when a Java method is
declared to take an int, getInt() will be called, and a C++ exception
will be thrown.  This change uses similar logic to
NativeReadableMap.getInt() to convert a folly::dynamic double to a
jint.  This will still throw an exception if the JS value cannot be
represented as a jint without loss.

Subject: [PATCH 193/273] check isAvailable key on simulator object (#21557)

Summary:
With the new xcode command line tools (10.1 beta2), running `xcrun simctl list --json devices` seems to gives us a slightly different format than what we were expecting. More specifically, the `availability` key is changed to `isAvailable` and returns `'YES'` if the simulator is available:

Before:
```js
devices: {
  'iOS 9.2': [
    {
      state: 'Shutdown',
      availability: '(unavailable, runtime profile not found)',
      name: 'iPhone 4s',
      udid: 'B9B5E161-416B-43C4-A78F-729CB96CC8C6',
    },
    {
      state: 'Shutdown',
      availability: '(unavailable, runtime profile not found)',
      name: 'iPhone 5',
      udid: '1CCBBF8B-5773-4EA6-BD6F-C308C87A1ADB',
    },
    ...
   ]
}
```
After:
```js
devices: {
  'iOS 12.1': [
    {
      state: 'Shutdown',
      isAvailable: 'YES',
      name: 'iPhone 6s',
      udid: 'D0F29BE7-CC3C-4976-888D-C739B4F50508',
    },
    {
      state: 'Shutdown',
      isAvailable: 'YES',
      name: 'iPhone 6',
      udid: 'BA0D93BD-07E6-4182-9B0A-F60A2474139C',
    },
    ...
   ]
}
```

Without this fix, `npm run ios` is not able to launch the simulator correctly and returns the following error:

```
Could not find iPhone 6 simulator

Error: Could not find iPhone 6 simulator

Summary:
this is just a suggestion, but as the iPhone 6 is discontinued by Apple
and the new iPhone line will match the X version, it could be good to update the default simulator.

it could also be the iPhone 8, feel free to suggest other changes!

Subject: [PATCH 197/273] Remove sinon dependency

Summary:
This diff removes the `sinon` dependency from `metro` and `react-native-github`. It was only used in a handful of tests and having to learn and remember another mocking API just for these cases was not worth it IMO.

While doing the migration, most of the things that `sinon` provides can be done with `jest` in a very similar (and user friendly) way.

I've found, though, two small things that are more user friendly with `sinon`. I'm documenting them here because it may be worth adding them to jest:

With `sinon`:

```
stub.throws(new Error('foo'));
```

With `jest`:

```
mock.mockImplementation(() => {
  throw new Error('foo');
});
```

Taking into account that `jest` has a `mockRejectedValue` method for mocks (to return a rejected promise) I don't see any reason why it does not have a `mockThrowError` method.

With `sinon`:

```
expect(mock1.calledBefore(mock2)).toBeTruthy();
```

With `jest`:

```
expect(mock1.mock.invocationCallOrder[0]).toBeLessThan(
  mock2.mock.invocationCallOrder[0],
);
```

There's a community matcher that adds this matcher in `jest-extended`: https://github.com/jest-community/jest-extended#tohavebeencalledbefore, but we're not using `jest-extended` in `xplat/js`.

Subject: [PATCH 198/273] Update to Detox 9 (#21570)

Summary:
Updating to Detox 9 - this should help with better Xcode 10 support, and should fix https://github.com/facebook/react-native/issues/21539.

I've updated to fixed `9.0.4` since it seems that each version is fairly different from the next, and I've followed the [migration guide](https://github.com/wix/detox/blob/master/docs/Guide.Migration.md#migrating-from-detox-8xx-to-9xx) for the android native dependencies.

Release Notes:

[INTERNAL] [ENHANCEMENT] [DETOX] - Update to version 9.0.4

Subject: [PATCH 201/273] Android ScrollView fix for snapToInterval not
 snapping to end

Summary:
The end-of-scrollable-range offset was not clipped before the nearestOffset calculation causing the ScrollView to not snap to the end of the view when the width of the ScrollView was not an exact multiple of snapToInterval.

Subject: [PATCH 203/273] Fix default accessibility delegate

Summary:
The current accessibility implementation tries to generalize every view's accessibility node info by setting an accessibility delegate on every view -- regardless of whether or not any accessibility properties are set. This delegate however doesn't correctly set the appropriate accessibility node fields for every view. For example, ScrollViews needs AccessibilityNode.setScrollable(true) set, but the generic delegate does not account for this. For now let's avoid unnecessarily
setting an accessibility delegate on views that don't have any accessibility props set, which will likely fix the majority of these issues.

Summary: D10138128 had some shamefully wrong boolean logic to determine whether we should customize the accessibility delegate. Previously, we did it if BOTH the accessibility label AND role were present. We should actually do it if EITHER are present.

Subject: [PATCH 210/273] Fix for InterpolatorType crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
We're currently getting a redbox in Turkish when we try to convert the string 'easeInEaseOut' to an InterpolatorType. This is because I use toLowerCase() to compare the string without setting a locale; in Turkish, the capital letter 'I' doesn't convert to 'i' when you lowercase it, but rather to 'ı' (http://www.i18nguy.com/unicode/turkish-i18n.html).

Passing in a locale param to `toLowerCase()` fixes it. Also updating the test.

Subject: [PATCH 214/273] Expose enableBabelRuntime config param externally

Summary:
Up until now the `enableBabelRuntime` option in the `metro-react-native-preset` package was hardcoded in the transformer: our internal transformer set it to `false` and the opensource one was `true`.

This diff now exposes this param out to the config of Metro (now that it's quite easy to expose things) so anybody can set it to false or true.

This allows our end to end tests to set it to false to not have to deal with requires to `babel/runtime`.

Android requires lowercase for URL scheme. This commit https://github.com/facebook/react-native/commit/d00bdb9bb8b9b11bce900689c7e28cebd2eb0807 fixed it but on React Native side.
Because it is Android specific, it should be fixed on Android side.

Android has method to normalize url scheme: https://developer.android.com/reference/android/net/Uri.html#normalizeScheme()
Pull Request resolved: https://github.com/facebook/react-native/pull/21561

Subject: [PATCH 224/273] Fix accessibility role crash

Summary: We were using a locale-specific `toUpperCase()` for accessibility roles. In the Turkish locale, `"image".toUpperCase()` does not become `"IMAGE"`; it becomes some weird turkish alphabet word, and we throw an error. This diff uses US-locale to avoid the error.

Summary:
**Problem:**
When you type an invalid regex into the input field of the RNTester app, it crashes. What's worse is that it remembers the input string so refreshing the view doesn't get rid of the error. Observe:

Subject: [PATCH 230/273] Fix DynamicFromMap object pool synchronization
 (#17842)

Summary:
DynamicFromMap internally uses SimplePool object to recycle dynamic prop objects. But the pool is not multi-thread safe. Currently the most used dynamic props are size props such as left, paddingVertical, marginTop and so on. These props are only accessed from the layout thread so the pool works fine. If a dynamic prop is needed in UI thread, then the two threads can access the same pool object and cause random errors. This PR make the pool object thread local to avoid synchronization. After this change there are two pool objects created in the process.

Tested in official Airbnb app after updating accessibilityComponentType to be dynamic.

Once this is merged, I'll send another PR to support "disabled" state in `accessibilityComponentType`.

Subject: [PATCH 235/273] Fix issue when inserting text at 0 when maxLength is
 set

Summary:
1. The user inserts a character ('0') at index 0. Because the range matches 0, 0, predictedText is set to that character that was inserted.
2. In textInputDidChange, it discovers a mismatch between the rendered text ('1234') and predicted text ('0')
3. This triggers textInputShouldChangeTextInRange to be called again with the 'new' text that it thinks was just added ('1234')
4. It goes to insert this text, but runs into the maxLength limit, so it gets truncated and then inserted.

(I'm not totally sure why only happens if maxLength is set - I need to look into that.)

One fix for this is to just get rid of the range check, but that'll regress #18374. I decided to just check and see if the rendered text is empty instead of checking the range where text could be inserted, since that seems like it should properly handle both cases.

Subject: [PATCH 237/273] Text: send metrics after rendering (iOS)

Summary: This adds a callback for <Text> to get metrics about the rendered text. It's divided by line but that could be changed to "fragments" (which makes more sense for multi-lingual). Right now by line is convenient as you frequently want to know where the first and last line end (though we could make this work with fragments I suppose).

Subject: [PATCH 238/273] Android: Send <Text> metrics in onTextLayout events

Summary:
@public
As we're doing in D9440914 (OSS 64a52532fe88b482ae4b998133d340e6e1141a0f), send text metrics in an onTextLayout callback. These can be used by surrounding views for doing complicated layout like:
- displaying a cursor at the end of text
- vertical centering using capheight-baseline

This right now isn't very performant but is only done when `onTextLayout` is set. I plan to optimize it with a capheight and xheight cache in a follow up diff.

Subject: [PATCH 240/273] Fix onTextLayout metrics on Android when using
 alignText

Summary:
With this, we send the correct x position when using center or right aligned text. In order to accomplish this though, we have to pass the text alignment into the Layout object that we create.

Also update RNTester to allow us to try different alignments.

Subject: [PATCH 241/273] Allow specifying iOS version for run-ios with
 simulator option (#19079)

Summary:
Fixes #19069

The --simulator option for the run-ios command now can take an optional
iOS version between parenthesis to further match the desired simulator.
This is useful if you have installed simulators for different iOS
versions and you want to run the app in an especific one. Example:

react-native run-ios --simulator "iPhone 6s (9.3)"

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.

Updated tests for the findMatchingSimulator function to include test cases specifying iOS version, and tested on the command line in my app to make sure it has the expected behavior.

[CLI] [ENHANCEMENT] [{/runIOS/findMatchingSimulator.js}] - run-ios command with the --simulator option now allows specifying the iOS version to run an specific simulator if you have multiple versions of the simulator installed. Example: `react-native run-ios --simulator "iPhone 6s (9.3)"`.

Subject: [PATCH 242/273] Relax the requirement that lazy module cannot be
 initialized on the main thread

Summary:
[RN] Relax the requirement that lazy module cannot be initialized on the main thread
I tried to understand the D5364734 that intoduced this, and I am not sure, but belive that asserting here is too strict. If you have a module that you want to lazily initialize, and module does not demand the main queue, it should be just a warning if you run on the main queue, not necessarily an error.

Summary:
Issue https://github.com/facebook/react-native/issues/2088 (closed, but a bit pre-emptively imo, since Android support was skipped)

Related (merged) iOS PR https://github.com/facebook/react-native/pull/18387

Related documentation PR https://github.com/facebook/react-native-website/pull/500

The basic desire is to have a declarative mechanism to transform text content to uppercase or lowercase or titlecase ("capitalized").
Pull Request resolved: https://github.com/facebook/react-native/pull/20572

Summary:
release method of local_ref and global_ref doesn't call deallocator, in fact, it leaves the caller responsible for deletion of the reference, while otherwise the reference is released on scope left.

Fixes #18292.

Subject: [PATCH 249/273] Fix InputAccessoryView safe area when not attached to
 a TextInput (#21179)

Summary:
When using an InputAccessoryView attached to a TextInput the safe area insets are not applied properly. This uses different autolayout constraints that works in all cases I tested, roughly based on the technique used here https://github.com/stockx/SafeAreaInputAccessoryViewWrapperView/blob/master/SafeAreaInputAccessoryViewWrapperView/Classes/SafeAreaInputAccessoryViewWrapperView.swift#L38.

Subject: [PATCH 250/273] Remove previously scheduled NetInfo callbacks if they
 haven't fired

Summary:
@public
If you call NetInfo.getCurrentConnectivity multiple times in succession, we'll create a bunch of callbacks but lose them in the ether.
With this fix, we'll unschedule them before creating a new one, which should resolve some crashes we're seeing.

Subject: [PATCH 255/273] Fix polyfilling of regeneratorRuntime to avoid
 setting it to undefined in some situations

Summary:
This diff fixes an issue that caused the problem with `regeneratorRuntime` last Friday (more info: https://fb.facebook.com/groups/frontendsupport/permalink/2427883350560427/).

The root issue is that both `InitializeCore` and `FBInitializeCore` are included in the same bundle, this fix just prevents the bundle from being invalid once this happens..

*copied from: https://our.intern.facebook.com/intern/diff/D10444264/?transaction_id=595485237532887*

The way that `regeneratorRuntime` is polyfilled is not correct:

```
polyfillGlobal('regeneratorRuntime', () => {
  // The require just sets up the global, so make sure when we first
  // invoke it the global does not exist
  delete global.regeneratorRuntime;
  require('regenerator-runtime/runtime');
  return global.regeneratorRuntime;
});
```

Since a `require`d module is only evaluated once (no matter how many times it's required), defining (and calling) a getter for `global.regeneratorRuntime` twice will end up storing `undefined` to `global.regeneratorRuntime`.

There were no issues before this diff because the ordering of requires made things work by coincidence, e.g the following code will work:

```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
  delete global.regeneratorRuntime;
  require('regenerator-runtime/runtime');
  return global.regeneratorRuntime;
});

// Set up regenerator for the second time. This will just override the previous getter (which has not even got executed so
// the `regenerator-runtime/runtime` module has not been evaluated yet.
polyfillGlobal('regeneratorRuntime', () => {
  // The require just sets up the global, so make sure when we first
  // invoke it the global does not exist
  delete global.regeneratorRuntime;
  require('regenerator-runtime/runtime');
  return global.regeneratorRuntime;
});

// Now access regenerator
global.regeneratorRuntime;
```

But the following code won't work:

```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
  delete global.regeneratorRuntime;
  require('regenerator-runtime/runtime');
  return global.regeneratorRuntime;
});

// Access regenerator. This will cause the previous getter to be called, and the `regenerator-runtime/runtime` module will get evaluated.
// Here, `global.regeneratorRuntime` will have a correct value.
global.regeneratorRuntime;

// Set up regenerator for the second time. This will define a new getter for `global.regeneratorRuntime`, which will delete `delete global.regeneratorRuntime`
// and return undefined (note that `require('regenerator-runtime/runtime');` is a noop since the module has been already evaluated).
polyfillGlobal('regeneratorRuntime', () => {
  // The require just sets up the global, so make sure when we first

Subject: [PATCH 257/273] Quote "$NODE_BINARY" in react-native-xcode.sh
 (#21383)

Summary:
Fix build errors when path to $NODE_BINARY contains spaces:

error: Can't find '/Path/With Spaces/To/node' binary to build React Native bundle

Why would $NODE_BINARY contain spaces? In my case, I am using sentry-cli which wraps the NODE_BINARY in it's own executable. The local path to the project, and thus the $NODE_BINARY, contains a space on my GoCD build agent.

'/Users/go/Library/Application Support/Go Agent/pipelines/my-ios-app/node_modules/sentry/cli/sentry-cli

Subject: [PATCH 263/273] Fix relayout of inline views (#21968)

Summary:
If a view inside of an inline view became dirty (e.g. its top/left prop changed), its position would not update on screen. This is because Yoga didn't know the view needed to be relaid out because Yoga's dirty signal didn't propagate all the way up to the root.

The problem is that inline views don't have a parent in the Yoga tree causing Yoga's dirtiness signal propagation to get cut off early. The fix is, when an inline views gets dirty, mark the parent Text's Yoga node as dirty. This will cause Yoga's dirtiness signal to propagate all the way up to the root node.

Yoga has a hook to inform you when your node is marked as dirty: `YGNodeSetDirtiedFunc`. We leverage this to find out when an inline view's Yoga node gets dirtied.

React Native almost handled this case. Everything worked fine as long as the inline view was nested inside of a virtual text node like this:

```
<Text>
  <Text>
    <InlineView />
  </Text>
</Text>
```

However, the bug repros when the inline view is nested in a non-virtual text node:

```
<Text>
  <InlineView />
</Text>
```

The fix is to move the special dirtiness propagation logic from `RCTVirtualTextShadowView` to `RCTBaseTextShadowView`.

**Test Plan**

Created an inline view. Tested the following kinds of updates on the inline view's content:
  - Moved the content
  - Removed the content
  - Added the content

Tested this for an inline view that is directly inside of a text node as well as one that is nested under a virtual text node.

Here's the code I used for the inline view that moved its content after 2 seconds:

```
const RN = require('react-native');
const React = require('react');

export default class InlineView extends React.Component {
  constructor(props, context) {
    super(props, context);
    this.state = { posBottom: false };
  }

Subject: [PATCH 267/273] Performance improvement for loading cached images on
 iOS (#20356)

Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.

This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.

Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.
https://imgur.com/a/cnL47Z0

More performance gains can potentially be had by increasing the size limit of RCTImageCache: https://github.com/facebook/react-native/blob/1a6666a116fd8b9e8637956de2b41a1c315dd470/Libraries/Image/RCTImageCache.m#L39 but this comes at the tradeoff of being more likely to run into OOM crashes.
