/**
* HasteMap is a JavaScript implementation of Facebook's haste module system.
*
* This implementation is inspired by https://github.com/facebook/node-haste
* and was built with for high-performance in large code repositories with
* hundreds of thousands of files. This implementation is scalable and provides
* predictable performance.
*
* Because the haste map creation and synchronization is critical to startup
* performance and most tasks are blocked by I/O this class makes heavy use of
* synchronous operations. It uses worker processes for parallelizing file
* access and metadata extraction.
*
* The data structures created by `jest-haste-map` can be used directly from the
* cache without further processing. The metadata objects in the `files` and
* `map` objects contain cross-references: a metadata object from one can look
* up the corresponding metadata object in the other map. Note that in most
* projects, the number of files will be greater than the number of haste
* modules one module can refer to many files based on platform extensions.
*
* type HasteMap = {
* clocks: WatchmanClocks,
* files: {[filepath: string]: FileMetaData},
* map: {[id: string]: ModuleMapItem},
* mocks: {[id: string]: string},
* }
*
* // Watchman clocks are used for query synchronization and file system deltas.
* type WatchmanClocks = {[filepath: string]: string};
*
* type FileMetaData = {
* id: ?string, // used to look up module metadata objects in `map`.
* mtime: number, // check for outdated files.
* size: number, // size of the file in bytes.
* visited: boolean, // whether the file has been parsed or not.
* dependencies: Array<string>, // all relative dependencies of this file.
* sha1: ?string, // SHA-1 of the file, if requested via options.
* };
*
* // Modules can be targeted to a specific platform based on the file name.
* // Example: platform.ios.js and Platform.android.js will both map to the same
* // `Platform` module. The platform should be specified during resolution.
* type ModuleMapItem = {[platform: string]: ModuleMetaData};
*
* //
* type ModuleMetaData = {
* path: string, // the path to look up the file object in `files`.
* type: string, // the module type (either `package` or `module`).
* };
*
* Note that the data structures described above are conceptual only. The actual
* implementation uses arrays and constant keys for metadata storage. Instead of
* `{id: 'flatMap', mtime: 3421, size: 42, visited: true, dependencies: []}` the real
* representation is similar to `['flatMap', 3421, 42, 1, []]` to save storage space
* and reduce parse and write time of a big JSON blob.
*
* The HasteMap is created as follows:
* 1. read data from the cache or create an empty structure.
*
* 2. crawl the file system.
* * empty cache: crawl the entire file system.
* * cache available:
* * if watchman is available: get file system delta changes.
* * if watchman is unavailable: crawl the entire file system.
* * build metadata objects for every file. This builds the `files` part of
* the `HasteMap`.
*
* 3. parse and extract metadata from changed files.
* * this is done in parallel over worker processes to improve performance.
* * the worst case is to parse all files.
* * the best case is no file system access and retrieving all data from
* the cache.
* * the average case is a small number of changed files.
*
* 4. serialize the new `HasteMap` in a cache file.
* Worker processes can directly access the cache through `HasteMap.read()`.
