Summary:
When I use local static files as Image resources, it will occur a 404 error if the image file's name contains some non-latin letters.
The reason is that the request's url will be encoded if it contains some non-latin letters.

Summary:
This is a very hacky solution to make reloads from packager faster for simple file changes.

Simple means that no dependencies have changed, otherwise packager will abort the attempt to update and fall back to the usual rebuilding method.

In principle, this change avoids re-walking and analyzing the whole dependency tree, and just updates modules in existing bundles.

ColCh 8edb952403 make fsop timeout injectable
Summary:
We have a weak build machine for React Native app: a poor Mac Book Air with HDD, which is very slow.

So, fs operations sometimes fail because of timeout.

We likely don't care about build time, but it's pretty annoying to restart builds sometimes.

In this PR I make timeout injectable via environment variable.

__USAGE__:
export this variable into environment. It's measured in miliseconds.
Example, for 1 minute timeout:
`export REACT_NATIVE_FSOP_TIMEOUT=60000`

If you don't specify it, it will remain default value: `15000`

This should not break anything, but repair slow builds.

Related to : #9373 , #8794 (I think so)

This PR should handle case of issue and close #9373

Mark Oswald 91ff6868a5 Use HTTP range requests (responses) to serve mp4 from assets
Summary:
This PR solves a problem when video assets are used from third-party React Native components (e.g. [react-native-video](https://github.com/brentvatne/react-native-video). The video will not work while the assets are served from the react native packager because the used video component (iOS) relies on HTTP range requests.

I added a small fix that allows ranged requests (e.g. mp4) to be served in ranges.

To test this:

1. make new react native project
1. add [react-native-video](https://github.com/brentvatne/react-native-video) to xcode project
1. add video component to your project
```
import Video from 'react-native-video';
var resolveAssetSource = require('react-native/Libraries/Image/resolveAssetSource');
/* ... /*
render() {
    let source = resolveAssetSource(require('./someVideoFile.mp4')) || {};
    return <Video /*....*/ source={source} />;
}
```

That should not work (if video is smaller than a few megabytes, open app a few times). Then add my fix, that should do the trick.

As result, when error is thrown in global scope, new JSC puts "global code" as function name, our parser chokes on it and thinks "global code@http://...." is a file name and sends it to packager. The packager can't resolve that URL and fails the whole symbolication request.

Summary:

* I'm trying to switch all tests off of jsdom on react-native. This should save 500ms of time when running a single test because jsdom is slow to load and react-native is also not supposed to run in a DOM environment, so let's not pretend we are providing the DOM in tests.
* Make the bridge config configurable so that when we disable automocking and we reset the registry we can redefine the value.

Oh also, stop using lodash in Server.js. First off, lodash 3 doesn't work in Jest's node env because it does some crazy stuff, second because we don't need to load all of lodash for debounce.

Summary:
When an asset is included in a module, and the directory for that asset can't be found in any of the roots, it is hard to debug that, because the error message contains neither the name of the requested file, the sub directory it is located in, nor the roots that have been searched for it. It becomes more difficult, because that exception is created asynchronously. It contains the calling promise code.

This diff makes the error message more useful by including the name of the file, the sub directory, and the roots.

Alex Kotliarskyi 62e74f3832 Symbolicate JS stacktrace using RN Packager
Summary:
The way we currently symbolicate JS stack traces in RN during development time
(e.g. inside the RedBox) is the following: we download the source map from RN,
parse it and use `source-map` find original file/line numbers. All happens
inside running JSC VM in a simulator.

The problem with this approach is that the source map size is pretty big and it
is very expensive to load/parse.

Before we load sourcemaps:
{F60869250}

After we load sourcemaps:
{F60869249}

In the past it wasn't a big problem, however the sourcemap file is only getting
larger and soon we will be loading it for yellow boxes too: https://github.com/facebook/react-native/pull/7459

Moving stack trace symbolication to server side will let us:
- save a bunch of memory on device
- improve performance (no need to JSON serialize/deserialize and transfer sourcemap via HTTP and bridge)
- remove ugly workaround with `RCTExceptionsManager.updateExceptionMessage`
- we will be able to symbolicate from native by simply sending HTTP request, which means symbolication
  can be more robust (no need to depend on crashed JS to do symbolication) and we can pause JSC to
  avoid getting too many redboxes that hide original error.
- reduce the bundle by ~65KB (the size of source-map parsing library we ship, see SourceMap module)

Eric Rozell ef21d99ded Adds packager configuration to support windows platform
Summary:
This pull request is a prerequisite to enabling the react-native-windows platform extension.

In the Resolver component, we need to add 'windows' to the list of platforms that are allowed in the DependencyGraph.  We also need to add 'react-native-windows' (the name of the Windows platform extension NPM module) to the `providesModuleNodeModules` option. This allows the node_module folder check in the DependencyGraphHelper from node-haste to be bypassed for *.windows.js files in the Windows NPM package.

For good measure, I also included a change to blacklist.js to ensure .windows.js files are ignored when the packager is parameterized on a platform.

Martín Bigio fdc6240018 Reset hasError flag after HMR request
Summary:
This got broken recently. As a result of this, when a module throws while being required, either by regular load or hot reload, the module object is marked as `hasError`. Form that point all subsequent HMR updates will fail because it will think the module failed while executing the factory but the failure could have been on an old run of an old factory.

The fix is very simple: just reset `hasError` to false when accepting a module.

Martín Bigio 6457effb7b Avoid clearing out factory on DEV mode
Summary:
grabbou pointed out this issue.

We recently started cleaning out the factory function after module are required to save some memory. This broke HMR on some edge cases because sometimes the factory function may need to be re-executed. This PR just wraps the optimization into `__DEV__` to make sure we don't use it while developing.
