Summary:
React Native bundler (aka Metro Bundler) was splitted from the main codebase some time ago (now it lives [[https://github.com/facebook/metro-bundler|here]]). To make it more agnostic, polyfills will be moved out from it, so people who doesn't need them does not include them. However, RN will still need them, so the first step is to copy them back to RN so that we can provide them to Metro Bundler later.
We also include a way of passing the list of polyfills to include, as an `Array<string>`. The field is called `polyfills`, and defaults to the traditional list that is currently included in the package manager [see here](be1843cddc/packages/metro-bundler/src/defaults.js (L27-L37)).
In future commits, `metro-bundler` will be able to manage the `polyfills` array passed to it, and use it, instead of the pre-defined ones.

Summary:
This diff cleans up some cruft and adds some features:
* It removes the usage of an env variable to control workers.
* It removes the lazy and handwavy calculation on how many workers to use for jest-haste-map. Jest itself uses the maximum amount of workers available and it has never been reported as an issue – especially since it is a one-time startup cost of about 3 seconds on a cold cache only.
* It adds a `--max-workers` flag to replace the env variable. This one is able to control both the number of workers for `jest-haste-map` as well as the transformers.
* It makes the transformers run in the parent process if 1 or fewer workers are are specified. This should help with debugging.
Once you approve this diff, I will publish a new version of metro to npm and update the version used in RN and remove the use of the env variable altogether: https://our.intern.facebook.com/intern/biggrep/?corpus=xplat&filename=&case=false&view=default&extre=&s=REACT_NATIVE_MAX_WORKERS&engine=apr_strmatch&context=false&filter[uninteresting]=false&filter[intern]=false&filter[test]=false&grep_regex=
Note: the process of adding a CLI option is really broken. Commander also has a weird API. We should consider building a better public API for Metro and then consider how to build a new CLI on top of it and simplify our internal integration. I really don't like how Metro is integrated across pieces of the RN cli in ways that is hard to manage. But that is a larger task for another time :)

Summary:
In <= 0.44, the default implementation of getProjectRoots() came from `local-cli/core/default.config.js`. With changes happening in the CLI and the packager over the course of the last two months, various pieces of this logic (specifically `local-cli/utils/Config.js`) were rewritten, and though default.config.js was still being imported and used in `local-cli/core/index.js`, the default `getProjectRoots()` was being overriden by the defaults specified in `local-cli/utils/Config.js`.
This PR moves the logic from default.config.js into Config.js and index.js, as appropriate. Specifically:
- The `getProjectCommands()`, `getProjectConfig()`, and `getDependencyConfig()` methods, which have traditionally not been part of the rn-cli.config.js spec, are now defined in `local-cli/core/index.js`.
- The `getProjectRoots()` method, which contained logic for properly resolving the _actual_ project root as well as resolving symlinks within that root, has been moved to `local-cli/utils/Config.js`, to match the fact that other default rn-cli.config.js definitions live there.

Summary:
This changeset moves the creation of the transform cache at the top-level of the bundler so that:
* we can use alternative folders, such as the project path itself, that I think will be more robust especially for OSS;
* we can disable the cache completely, that is useful in some cases (for example, the script that fills the global cache).
The reasons I believe a local project path is more robust are:
* there are less likely conflicts between different users and different projects on a single machine;
* the cache is de facto cleaned up if you clone a fresh copy of a project, something I think is desirable;
* some people have been reporting that `tmpDir` just returns nothing;
* finally, it prevents another user from writing malicious transformed code in the cache into the shared temp dir—only people with write access to the project have write access to the cache, that is consistent.

Summary: For the Buck integration (work-in-progress), we want to add the ability to do some custom preprocessing similar to the packager server. The signature is different so I prefer to have a separate function for that. Also we don't need the transform options right now, I suggest we don't add them for now and add them later if necessary.

Summary:
After examining how React Native sets up `process.env.NODE_ENV` using `global.__DEV__` from `prelude_dev.js` or `prelude.js` by treating them like polyfills I decided to use the same approach for environment variables. I setup my own rn-project.config.js file like so:
```
const blacklist = require('react-native/packager/blacklist');
const pathJoin = require('path').join;
module.exports = {
getBlacklistRE: function() {
return blacklist([/build\/.*/, /app\/assets\/webpack.*/]);
},
polyfillModuleNames: [pathJoin(__dirname, 'globals.js')]
};
```
I ran the packaging server using:
`react-native start --config=config/react-native/rn-project.config.js --reset-cache`
I expected my polyfillModuleNames to be passed into the Packager properly and be handled the same way the built-in polyfills worked. Unfortunately I noticed the Packager wasn't actually getting `opt.polyfillModuleNames`. Digging into the code a bit, it seems the local-cli wasn't passing the polyfillModuleNames from the config.
There are no specs for runServer.js but this change can be tested by using a config that contains polyfillModuleNames. Sample config and run command provided above simple `global.js` provided below:
```
global.process = global.process ? global.process : {};
global.process.env = global.process.env ? global.process.env : {};
global.process.env['PROJECT_ENV'] = 'staging';
```

Summary:
Support symlinks under `node_modules` for all local-cli commands. PR https://github.com/facebook/react-native/pull/9009 only adds symlink support to the packager.
But other cli commands like `react-native bundle` creates its own instance of packager that doesn't have symlinks as part of its project roots, which results in the bundler breaking since it cannot find modules that you have symlinked.
This change ensures all `local-cli` commands add symlinks to its project roots.
Test plan (required)
1. Create a symlink in node_modules (for instance use npm/yarn link)
2. Run `react-native bundle`.

Summary:
This is step one on merging the `rnpm` config with the `cli config`. The plan is to remove two sources of truth (rnpm package.json config and rn-cli Javascript config)
Rationale:
As of now, we have `rnpm` config, that used to live in the `local-cli/core/config/index.js` and the `rn-cli` config, living in `default.config.js` and `utils/Config.js`.
This PR moves all the things into one file, called `local-cli/core', simplifies things, enhances types (Config now has better types, added missing properties and fixed descriptions).
One notable addition is that users can now opt-in to override the commands that are loaded at the package level. Previously it was only possible to add a command by writing a plugin. Now, you can just tweak the `rn-cli.config.js`.
This is one of the several improvements I have on my roadmap, with better documentation for the CLI as well.

Summary:
Instead of exposing a `getTransformOptionsModulePath` function in configurations, we can simply expose a `getTransformOptions` *function*. The necessity of exposing a path comes from the olden days, where we had a server listening on a socket, and a client, talking to that server.
Since that architectural gem no longer exists, we can use functions directly, rather than passing paths to modules around.

Currently we just try to resolve a rn-cli.config.js file by walking up the tree from node_modules/react-native. In non-standard uses of RN, when your copy of RN may not live within node_modules, it's impossible to use rn-cli.config.js. This PR adds a "config" flag to the cli that let's you pass in a path to rn-cli.config.js.

In order to see the problem, you need to have the packager search for the configuration in a place that doesn't have one and the default configuration can't be provided. It's likely that no one is doing this and also why this probably wasn't seen.
