Summary: It seems we don't need that one much anymore, as we have a FS-based cache for files, and removing the last callsites doesn't really change perf, as we have to read these files eventually (plus some of these are read from `HasteMap`, that I believe is already dead code).

Summary:
**Bug Description**
The FlatList component receives content items via the data prop, and renders an initial number of items on the app's view. When a user scrolls to the end of the list, the component will append and render more available items at the end of the list. There was a bug where when the content was filtered, there were more available items but the component did not append/render them. This is due to the current appending/rendering logic in VirtualizedList, which does not account for data changes as a condition for updating/rendering. VirtualizedList is a dependency of FlatList, so this issue affects FlatList as well.
**Approach to Fixing Bug**
(i) Reproduce bug on iOS view of FlatList.
(ii) For VirtualizedList component:
# Isolate onEndReached function that appends more data to component UI.
# Isolate _onContentSizeChange function that is called when list content changes.
# Write snapshot tests using jest, based off existing test for FlatList.
# Refactor logic to append more data to list into _maybeCallOnEndReached function.
# Call _maybeCallOnEndReached in both _onContentSizeChange and _onScroll.
(iii) Run snapshot tests and observe jest output.
(iv) Bring up iOS view of FlatList and check that component now renders more items when content is filtered.

`Promise.done` is non-standard, `Promise.then` is preferred as a standardized method. On Android, polyfill filling in `Promise.done` has been most probably taken out in newer versions of `react-native` and app crashes when it tries to query network state through `NetInfo`.

Summary:
Don't build js bundles for debug simulator build configurations
Motivation:
We have more than one debug build configuration that we run in the simulator, and none of them are exactly named 'Debug'. We want to establish the convention that any simulator build configuration containing the word 'Debug' will not build the react js bundles. We believe this is less intrusive to the developer.

in some navigators) and hopefully it's not necessary with JS-side windowing. If people need the

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 😉

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'
```
