`babel-plugin-react-transform` doesn't support to run on transformed code (it doesn't detect some react components). The reason why HMR was originally on the internal transform was so that it worked with non JS code (TypeScript, Coffeescript, etc), but looks like this is not very popupar in the community, maybe because the JS ecosystem is getting better everyday.
So long story short, for now lets move HMR to the external transformer. This should also give us a perf boost.

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

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:
At the moment we have to disable strict mode for the transform-es2015-modules-commonjs because strict mode leaks to the global scope and breaks the bridge. It was due to the way the polyfills were bundled in the package. To fix it, I wrapped the polyfill modules in an IIFE. Then when strict mode was enabled some polyfills were broken due to strict mode errors so that was fixed too. Also removed the IIFE from the polyfills that included one.
This diff doesn't enable the strict mode transform since some internal facebook modules depend on it not being enabled. When #5214 lands we could make the default babel config shipped with OSS react-native use strict mode modules and facebook could just modify the babel config to disable it if needed.
This will allow removing `"strict": false` from https://github.com/facebook/react-native/blob/master/packager/react-packager/.babelrc#L16Fixes#5316

Summary:
We used to only cache the `dependencies` and `name` of a Module but we were actually accessing two more fields (async dependencies and the `isHaste` field) which meant we were always reading every single file from disk. In D2644383 I noticed that but realized that the Promise was cached, meaning we would read every file once *per instance* and I didn't think about cross-instance reads over time. My initial version added more caching (but also missed the `isHaste` field) but then I got rid of the cache call for `dependencies`. So my change from before didn't make anything worse but it also didn't make anything better. This change now caches everything until the contents of the file actually changes.

Summary:
One consequence we didn't predict after introducing the Internal Transform Pipeline, was that when the workers would get started, we won't require the external transformer the user specified up until the first time each worker received a job. There're 2 visible consequences of this: (1) the transform progress bar seems to get stuck for about 5 seconds the first time the packager receives a request and (2) the first N (# of cores) HMR requests take way longer (about 4 seconds with FB's transformer instead of << 1 second) as we need to require lots of modules.
This diff creates a temporary file for the js transformer workers that requires the user-specified transform file eagerly.
That makes sure workers have imported babel and the transforms before receiving the first request.
There are better ways to do this, like adding an `init()` method to the workers and call that eagerly. I will follow with another diff doing that.

I'm working on deploying haste2 with jest. This updates all the files that require changes for this to work and they are backwards compatible with the current version of jest.
* package.json was just outdated. I think haste1's liberal handling with collisions made this a "non-issue"
* env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already?
* some things were mocking things they shouldn't
* Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter.

Fixes a terrible bug due to which when Hot Loading enabled when the user reloads we'll serve them the first `hot` bundle he requested. This happened because when HMR enabled we bailed out after sending the HMR updates and didn't rebuild any of the bundles the user requested before. As a consequence, when they reload we'd sent him the first and only one we ever built.
The fix is to tweak the hmr listener to return a promise. This way we can run the remaining code on the file change listener just after the HMR stuff finishes. We need to do it this way to avoid the remaining stuff to compete for CPU with the HMR one and give the best possible experience when HMR is enabled.

We want to support Hot Loading on the packager itself instead of on the transformer. This will allow us to enable it on OSS (and for any scripting language, yay!).
For now to enable Hot Loading the packager's internals transforms need to be manually enabled (start packager with `--enable-internal-transforms`). I think the internal pipeline should always be enabled as it doesn't affect performance if there're no transforms and the user can disable Hot Loading through the setting on the app though. I'll tweak this on a follow up commit.

Before this diff we were only accepting the module that was modified but the user. This works fine as long as the user doesn't modify the dependencies a module has but once he starts doing so the HMR runtime may fail when updating modules' code because they might might a few dependencies. For instance, if the user changes the `src` a `Image` has to reference an image (using the new asset system) that wasn't on the original bundle the user will get a red box. This diff addresses this by diffing the modules the app currently has with the new ones it should have and including all of them on the HMR update. Note this diffing is only done when the we realize the module that was modified changed it's dependencies so there's no additional overhead on this change.

This diff introduces an internal transforms pipeline that integrates with the external one. This has been a feature we've been looking to implement for a long time to use babel instead of `replace` with regexps on many parts of the packager.
Also, to split the bundle we'll need to run one transform. Internally for Facebook we can run the system-import transform altogether withe the other ones. For OSS we offer `transformer.js` which people can use out of the box if they're writing ES6 code. For those people, `transformer.js` will also run the internal transforms`. However they might want to tune the transforms, or even write the code on another language that compiles to Javascript and use a complete different transformer. On those cases we'll need to run the external transforms first and pipe the output through the internal transforms. Note that the order it's important as the internal transforms assume the code is written in JS, though the original code could be on other scripting languages (CoffeeScript, TypeScript, etc).

Summary:
We don't (yet) treat these the same as any other modules because we still have special resolution rules for them in the packager allowing the use of `providesModule`, but I believe this allows people to use npm react in their RN projects and not have duplicate copies of React. Fixesfacebook/react-native#2985.
This relies on fbjs 0.6, which includes `.flow` files alongside the `.js` files to allow them to be typechecked without additional configuration. This also uses react 0.14.5, which shims a couple of files (as `.native.js`) to avoid DOM-specific bits. Once we fix these in React, we will use the same code on web and native. Hopefully we can also remove the packager support I'm adding here for `.native.js`.
This diff is not the desired end state for us – ideally the packager would know nothing of react or fbjs, and we'll get there eventually by not relying on `providesModule` in order to load react and fbjs modules. (fbjs change posted here but not merged yet: https://github.com/facebook/fbjs/pull/84.)
This should also allow relay to work seamlessly with RN, but I haven't verified this.

Summary:

Before this this when a file was changed besides sending the HMR update we rebuild every single bundle that the packager had build (to serve it faster when the user hit cmd+r). Since when hot loading is enabled we don't do cmd+r all this work was pointless (except for when you're developing multiple apps using the same packager instance at the same time, which we can assume is very uncommon). As a consequence, the HMR update was competing with the rebundling job making HMR quite slow (i.e.: on one huge internal app it took up to 6s for the HMR changes to get applied).
So, this diff tweaks the file change listener so that we don't rebundle nor invoke the fileWatchers (use for live reload which is also useless when hot load is enabled) when hot loading is enabled. Also, it makes the HMR listener more high pri than the other listeners so that the HMR dev experience is as good as it can get.

Summary:

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).

Summary:
There's quite a bit of code scattered around the packager regarding ignoring the `providesModule` Haste pragma in any file that isn't in `react-native`, `react-tools` or `parse`. There is even a (passing) test case.
However, there's an edge case.
Take, for example, `fbjs`. It has a module inside of it called `ErrorUtils`. `react-relay` requires this file normally, in Common.JS style, by doing `require('fbjs/libs/ErrorUtils')`. But when `react-native` attempts to require `ErrorUtils` using the HasteModule format (in it's JavaScript initialization), it resolves the `fbjs` `ErrorUtils` module, instead of RN's `ErrorUtils`.
This happens, it turns out, because when a module is read (in `Module._read`), it's not caring about whether or not it should pay attention to `providesModule`, and is just assigning the `providesModule` value as the id of the module no matter what. Then when `Module.getName` is called, it will always use that `data.id` that was set, thus creating the wrong dependency tree.

Currently, the app server accepts `transformModulePath` which allows us to use different transformation variants. However, these options persist through the lifetime of the server. So we cannot conditionally transform a module differently for two bundles without restarting the server with different options.
`getTransformOptions` basically allows us to change the options to the transformer at runtime based on the bundle and module being transformed.
These options are also used as a cache key for the transformedSource to ensure that if a file is transformed with different options, caching doesn't cause any inconsistencies.

That means that on Windows systems, the generated URL path has backslashes rather than forward slashes which breaks the app's ability to retrieve image assets using require('./image.png'). This change fixes this by checking path.sep and replacing backslashes with slashes on systems that require it.

Summary:

Introduce a new Polyfill module to load bundles. This polyfill contains the function to which System.import gets transformed into. It works similarly to require in the way it's registered. It keeps track of the bundles that have ever been requested using promises, either fulfilled or not. The use of promises makes the implementation quite easy as we don't need to differenciate whether the request has been started or not.
There're a couple of follow up steps that still need to get done:
- Included this polyfill on the ones we automatically include on the bundle.
- Modify the transform to include the modules the user is actually requesting and pipe that through loadBundles so that the promise, once resolved, has the ordered list of modules the user requested.
- Implement the actual native code that loads a bundle. This shouldn't be that taught as native will be able to assume it will never receive the same request twice.

Summary: Extracts the module system from the list of dependencies and adds it back to the bundling process.
Unbundling and Prepack has their own module systems. jest does as well. This is not normally part of the resolver, nor polyfills.
In fact, I think we'll eventually start treating polyfills as normal modules just like core-js.
The prelude is the weird part right now but I think that we'll eventually move the DEV flag to be module level instead of global and we can just get rid of this prelude.

Summary: React Native is a lot more powerful an environment than the browser, so we need an alternate mapping, as specified [here](https://github.com/defunctzombie/node-browser-resolve#browser-field)
An example:
```js
{
"browser": {
"./lib/server": false
},
"react-native": {
"dgram": "react-native-udp",
"fs": "react-native-level-fs"
},
"chromeapp": {
"dgram": "chrome-dgram",
"fs": "level-filesystem"
}
}
```
on the other hand, if "react-native" is not present in package.json, you should fall back to "browser"
other than the one (nesting) test added, the tests are unchanged, just done for both "react-native" and "browser"
(I've implemented [react-native-udp](https://npmjs.org/package/react-native-udp) and [react-native-level-fs](https://npmjs.org/package/react-native-level-fs), but they obviously don't belong in the traditional "browser" field as they won't run anywhere except in React Native.)

Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

Summary: I'm planning to split up `DependencyResolver` into the react-native specific implementation of it and a new, generic resolver that is going to replace `node-haste` for jest and other places where we might need JS dependency resolution.
The plan is to split the two folders up so that:
* `Resolver` is the folder for all the react-native specific resolver code
* `DependencyResolver` will become a standalone library, eventually moving into a package called `node-haste`.
There is still a lot to be figured out. This is just the first diff of likely many. The current goal is to make `DependencyResolver` standalone to be able to create an instance of a resolver and resolve all dependencies for a file. This is when I can start integrating it more seriously with jest.
This diff simply moves a bunch of things around and turns `HasteModuleResolver` into an ES2015 class ( :) ).

**This PR includes:**
- A fix to the problematic regular expression
- Updated tests that support the new line style.
**Summary:**
We found out that while the packager does its module wrapping thing for lines like this:
```js
import theDefault, { named1, named2 } from 'src/mylib';
```
It fails to do the same for multi line imports:
```js
import theDefault, {
named1,

This moves us from warnings on name collisions to errors. If the error happens in initialization it will fatal out.
However, if the error happens while working (after initialization) then I did my best to make it recoverable. The rational behind this is that if you're working and you're changing names, you may introduce a duplication while moving things around. It will suck if you have to restart the server every time you do that.

Since we added packager-managed assets -- internally we still think of asset dependency as a single "module". In reality there are multiple files that represent this module. This becomes important with the `getDependencies` API which is used by Buck to inform it on what to rebuild. Since `getDependencies` deals with modules, and is more of an internal API, I've introduced a new one and would go on to deprecate this.

We swallow errors like it's nobody's business :(
Having an error handler that `reject`s after the promise has been resolved is a no-op. In node, if there is no `error` event handler then the error would throw.
So after we start listening and we want to resolve the promise, we remove the error listener so that we make sure errors actually throw.
Finally, I made the `uncaughtError` handler log `error.stack` so we can get an idea of what's going on.

The server dies after 30 seconds if it has no jobs on it's queue. The problem is that the jobs counter gets decreased before returning the bytes to the client. As a consequence, it's possible that the server dies while it's returning the bytes to the client, or just after it finished returning the bytes to the client.
To avoid both issues lets move the counter decrease a few lines below and bump the timer to make sure we have time to fully write the bytes on the socket and let the client close the connection before the server dies.

1. When the server starts up, it only gives itself 30 second to live before receiving any connections/jobs
2. There is a startup cost with starting the server and handshaking
3. The server dies before the client has a chance to connect to it

1. While the server should die pretty fast after it's done it's work, we should have a longer timeout for starting it
2. I also added accompanying server logs with client connection errors

Summary:
Saw an issue with a build because of an ENONT error: https://fb.facebook.com/groups/716936458354972/permalink/923628747685741/
My hypothesis:
1. We issue a ping to the socket (in SocketInterface/index.js) a decides if the available socket is alive
2. We see that it's alive but by the time we actually connect to it the server would've died
Solution:
1. The server shouldn't die as long as there are clients connected to it (currently it only stay alive as long as there are jobs)
2. The "ping" should only disconnect once the client is connected
3. Finally, have a better error message than ENOENT
Summary:
Sourcemap urls were generated as just the pathname (no options) which meant that they generated source for the wrong bundle.
Even worse, there exists a race condition when multiple request to the same bundle has different types of paltform arguments (in this case one could be 'ios' and the other is undefined). The fix will this will come later as it's more involved -- will need to refactor the dependency resolver to have a per-request state.
Summary:
Fix failing test that matches the exact error string to match using `contains`.
I was under the impression that jest tests were running in CI -- turns out not yet.
Summary:
A few potential races to fix:
1. Multiple clients maybe racing to delete a zombie socket
2. Servers who should die because other servers are already listening are taking the socket with them (move `process.on('exit'` code to after the server is listening
3. Servers which are redundant should immediatly die
