Summary:
The introduction of groups for random access bundles broke hot module reloading, because HMR uses a different Bundle class. And that didn’t have the `setRamGroups()` method.
This just adds an empty method on the base class.

Summary:
Adds the possibility to specify an array of files (group roots) that are used to bundle modules outside of the “startup section” into bigger groups by colocating their code.
A require call for any grouped module will load all modules in that group.
Files contained by multiple groups are deoptimized (i.e. bundled as individual script)

Summary:
For example, I could have a root named `random` and another root named `randomColor`.
A child of `randomColor` would **incorrectly** pass as a descendant of `random`.
So this commit changes `isDescendant` to do 2 things:
- check for exact matches (eg: the path is a root)
- call `startsWith` like before, but append `path.sep` to avoid false positives

Summary:
This piece of code can assemble all transitive dependencies of a set of entry modules. It is supposed to replace `ResolutionRequest.getOrderedDependencies`.
It has the following advantages:
- has minimal API surface to other components of the system (uses two functions, exposes one function)
- allows to separate concerns into loading + transforming files, resolving dependencies, gathering all modules belonging to a bundle (this code), and bundling
- allows to specify multiple entry points
- allows to use any kind of dependency ID as entry point (haste IDs, node module IDs, relative paths, absolute paths – depends on the resolver)
- allows to skip files, which allows callers to incrementally update previously retrieved collections of modules

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.

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.

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.

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)

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.

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.

Summary:We weren't passing `transformOptions` to `getShallowDependencies`, and therefore, when this method was called on a module, it would bust the cache and cause a retransform of the file. This was resulting in a complete retransforming of all files when the HMR Client connected to the packager.

Summary:Remove Trailing Spaces.
Why:
Sometimes there are conflicts with trailing spaces
Saves space
Those whose tools automatically delete them will have their pr watered down with trailing space removal

Summary: The HMR codepath is currently broken because of a recent change that tries to compute the absolute entryFile path (needed for RAM Bundling). HMR Bundler's bundles are special as they contains a single file (the file that was transformed). However, for performance reasons we recycle an existing resolution response which contains the polyfills and the module system modules.

Summary:Source maps are broken on Genymotion right now as they aren't being loaded from the correct URL. refer - https://github.com/facebook/react-native/issues/5338#issuecomment-188232402
**Test plan**
Build and install UIExplorer from master branch in genymotion and enable hot reload. When you change a file and save it, you'll see a Yellow box due to source map fetching failed, as per the referenced comment.
Doing the same for this branch doesn't produce any yellow boxes.

Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

Summary:`/assets/...` requests previously supported path-traversal potentially exposing and serving (private) files outside roots.
**Test plan**
Prior to patching perform the a path-traversal request to the server:
```
GET /assets/../../../../etc/hosts HTTP/1.1
Cache-Control: no-store
Host: 127.0.0.1:8081
Connection: close
Accept-Encoding: gzip
User-Agent: okhttp/2.5.0
```
Apply patch and verify a `404` response with body: `Asset not found`
Test normal asset requests work.

Summary:We recently refactor the packager to transform the module names into numeric IDs but we forgot to update the HMR call site. As a consequence, HMR doesn't work the first time a file is saved but the second one.
This is affecting master as of 3/20. If we don't land this before v0.23 is cut we'll have to cherry pick it. This rev does *not* need to be picked on v0.22.

Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”
- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated
Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual

Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

Summary:This rev adds support for production sourcemaps on RAM.
When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.
To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.
