Edward Coleridge Smith 654d7595fe Update terminal title to 'Metro Bundler'
Summary:
I noticed in v0.50.0 all mentions of 'packager' were updated to 'Metro Bundler':

12eb04b236

It seems like command which launches the bundler still sets the terminal title to 'React Packager'. This PR simply updates the title from 'React Packager' to 'Metro Bundler'.

Run `scripts/launchPackager.command`/`scripts/launchPackager.bat` and check title:

Valentin Shergin c3139d798a Fixed crash happenned on deallocating RCTSurface
Summary:
Essentially, we had `dispatch_async` inside `delloc` method which tried to retain `self`, which is disallowed operation in ObjC runtime.
However, we don't need to notify anything `surface`-related in `_stop` because it always is called from `dealloc`.

Valentin Shergin d9e5b313bb Helpers for proper conversion float values between CG and YG representations
Summary:
Yoga and CoreGraphics have different opinions about how "infinity" value
should be represented.
Yoga uses `NAN` which requires additional effort to compare all those values,
whereas GoreGraphics uses `GFLOAT_MAX` which can be easyly compared with
standard `==` operator.

Messing with this can cause super weired bugs like 100% CPU load for couple of seconds somewhere in CoreGraphics.

Michael S. Kazmier 33d710e8c5 adds --port option to `react-native run-ios` as well as patches port …
Summary:
The pull request adds the `--port` option to `run-ios` allowing a developer to build and launch a react-native app using a single command line like this:
```
react-native run-ios --port 8088
```

It defaults to the current port 8081.

This pull request fixes issue #9145 and issue #14113.

This patch also extends `run-android` to properly test and launch the packager with the specified port, extending the work done in PR:  ##15316

1. Create a new react-native app, or simply clone this branch and then update your version of react-native using `yarn add file:./path/to/this/fork/of/react-native`
2. run `react-native run-ios --port 8088`
3. watch the packager start on the desired port (8088 in this case) and watch your app in your simulator connect to the packager and launch the app.

Josh Hargreaves c9ff0bc212 Implement onKeyPress Android
Summary:
This implements onKeyPress for Android on TextInputs and addresses https://github.com/facebook/react-native/issues/1882.
**N.B. that this PR has not yet addressed hardware keyboard inputs**, but doing will be fairly trivial. The main challenge was doing this for soft keyboard inputs.

I've tried to match the style as much as I could. Will happily make any suggested edits be they architectural or stylistic design (edit: and of course implementation), but hopefully this is a good first pass :).
I think important to test this on the most popular keyboard types; maybe different languages too.
I have not yet added tests to test implementation, but will be happy to do that also.

- Build & run RNTester project for Android and open TextInput.
- Enter keys into 'event handling' TextInput.
- Verify that keys you enter appear in onKeyPress below the text input
- Test with autocorrect off, on same input and validate that results are the same.

Below is a gif of PR in action.

Matt Sessions a8391bde7d SectionList renderItem should be optional
Summary:
`renderItem` on `SectionList` is within the `OptionalProps` group of props but it is not actually marked as optional. Which means that doing things such as in the example where each section has its own `renderItem` and no `renderItem` prop is passed into `SectionList` will fail flow.

Create a `SectionList` where each section has it's own `renderItem` and do not pass in a `renderItem` into `SectionList`. Run flow, it should error.

In Android emulator, the host of `SourceCode.scriptURL` is same with `PlatformConstants.ServerHost` so we can just replace it.

* Tested on iOS device with [react-devtools](https://github.com/facebook/react-devtools/tree/master/packages/react-devtools) package.
* Tested on Android emulator, the `getDevServer` module got the correctly hostname so that don't need `adb reverse`.

Mark Amery 52f350a9cb Add proptypes for scrollview drag start & end handlers
Summary:
`ScrollView` has a bunch of `onFoo` handlers for scrolling-related events, most of which have a proptype defined and are documented. However, `onScrollBeginDrag` and `onScrollEndDrag` do not currently have a proptype and are not currently documented (as noted at https://stackoverflow.com/a/41793747/1709587). It seems reasonable to bring consistency and to provide documentation of these otherwise hard-to-discover props.

I haven't added or run any tests, and don't plan to do so (beyond waiting and seeing that no existing checks fail in CircleCI).

I have also created a PR to update the documentation at https://github.com/facebook/react-native-website/pull/99

Rebuilding should be rarely needed, but in this case we did need a newer BUCK version

To run tests locally:

npm run test-android-run-unit-test
```

If a newer android-base image is needed, just run `npm run test-android-build-base` to rebuild the image locally. Ping hramos if the Docker hub image is too out of date.

Logan Daniels 3559e42c55 Make sure VirtualizedList's windowSize is greater than 0
Summary:
Setting `windowSize = 0` doesn't make sense. Let's make sure we catch this problem in the constructor so that it doesn't cause inexplicable list behavior.

Also fixed an invariant in `VirtualizeUtils` that is meant to prohibit non-monotonically-increasing offset arrays. As written, the invariant condition can never actually be violated.
