Summary:
It's just causing problems (e.g. when combined with transform animations like those used
in some navigators) and hopefully it's not necessary with JS-side windowing. If people need the
perf, they can turn it on themselves.
Should fix https://github.com/facebook/react-native/issues/13316 and related issues.

Summary:
Note: if this changeset causes some breakage, consider disabling rather than reverting. To disable, the call to `_preprocessPotentialDependencies` in `ResolutionRequest` can be removed.
It's a bit of an experiment. I couldn't see any particular regression caused by this, but I could see net improvement of the global cache performance, as it unlock much, much stronger batching: indeed, instead of discovering dependencies progressively, we synchronously figure out the list of all potential modules of a bundle, and kick-off cache fetching and/or transformations. So when it comes to fetching from the global cache, it'll do less requests, and each requests will ask for considerably more keys at a time.
Potential problem caused by this changeset: if a module's dependencies completely changed, then the first time we try to build the bundle it'll start transforming modules that we probably don't care at all anymore, spending precious CPU time for nothing. I've been thinking about it and I cannot see such a case happening much often. Even if it happens, it should not cause any bug or corruption, it would just take additional time.
Other potential problem: that this new code doesn't handle some types of edge cases. It's quite hard to figure out what could possibly break in the `ResolutionRequest` code (and I think it would benefit from a larger refactor). We do have a good test coverage for `DependencyGraph` and it seems to work smoothly, so I'm relatively confident we're not breaking edge cases.

Hello!
The [Geolocation API](https://facebook.github.io/react-native/docs/geolocation.html) is currently not mocked in Jest, which often leads to an `Invariant Violation: Native module cannot be null` error. This patch adds a basic Jest configuration similar to the existing ones for the other modules.
None unfortunately, but this patch makes my test suite all green 😉
Thanks,
William

Summary:
The current mock of `AsyncLocalStorage` seems to mock parts of the
`AsyncStorage` API that can't be found on the `AsyncLocalStorage`
object itself and therefore it doesn't work as expected.
What it should do is mock the API of `AsyncLocalStorage` which is a
`NativeModule` so that the `AsyncStorage` module can be used in tests
and it will require the mocked methods.
In order to enable behaviour in unit tests it is possible to replace or
overwrite the mock implementation, see the [jest guide on mocks](https://facebook.github.io/jest/docs/mock-functions.html).
By doing something similar to:
```javascript
import { NativeModules } from 'react-native';
const { AsyncLocalStorage } = NativeModules;
// mock 'multiGet', in order to allow 'AsyncStorage.getItem('myKey')'
AsyncLocalStorage.multiGet.mockImplementationOnce((keys, callback) => {
callback(null, [['myKey', 'myValue']]);
});
// execute unit tests for code that makes use of 'AsyncStorage'
```

Summary:
A nice bit of polish for apps is to update the separators between list items
when press actives the highlight (things get especially noticeable/ugly when
the separators are not full width and don't adjust). This can be difficult to
coordinate and update efficiently, so we bake the functionality into
`VirtualizedList`.
The approach taken here is a little different from `ListView`. We pass a new
`separators` object with `renderItem` that has easy-to-use callbacks for toggling
the 'highlighted' prop on both adjacent separators - they can be wired up
directly to the `onShow/HideUnderlay` props of `TouchableHighlight` (pit of
success and all that - we want those RN apps to be polished!), but we also
provide a more generic `separators.updateProps` method to set any custom
props. This also passes in `leadingItem` so more custom wiring can be done on
initial render (e.g. linking the highlight state with `Animated`).
This also moves the separator rendering into the `CellRenderer`. I think this might
also fix some subtle measurement bugs with the `onLayout` not capturing the
height of the separator, so that's nice too, but the main reason is to have
an easy place to store the state so we don't have to re-render the entire list
like `ListView` does. Instead we track references to the cells and call update
only on the two we care about so the feedback is instantaneous even with big,
heavy lists.
This diff also messes with a bunch of flow and updates the example to be more
like a standard list.
`SectionList` support is coming in a stacked diff.

Summary:
ericvicenti Here is the latest updates and fixes for the container testing. Everything should be good to go now, the update for `inotify.max_user_watches` should fix the E2E test issues you were seeing locally.
The update to the packer prevents excessively large filename lengths due to the hash used in the name and splits them into directories instead. I was getting errors locally on the E2E because the hash filename was over 248 characters which was causing issues on the base image file system. It might not have appeared in circle due to another file system being used with different limits. I can separate it out into another PR if you want though.
* Turned jenkins instrumentation parallelism up to 3
* Disabled various instrumentation tests that seemed to have inconsistent results from
Jenkins by default
* Install google-chrome in the android base image so the chrome debug E2E test does not fail
* Turned back on E2E tests

Summary:
I have been working on integrating React Native into an existing app and realised that the source folder for android code is currently hardcoded as `app`. Being a legacy codebase we can't really change that. So I wanted to be able to customise this folder name so that I can integrate RN seamlessly and start it from the CLI without having to run it from Android Studio.
- Create a barebones RN app
- `react-native run-android` works successfully
- Refactor the name of the app folder inside the android directory to `TestFolderName` using Android Studio
- `react-native run-android` now fails
- Changing this command to `react-native run-android --appFolder=TestFolderName` works successfully
