+/**
+ * Helpers for dealing with resource paths stored in IndexedDB.
+ *
+ * Resource paths in their canonical string form do not sort as the server
+ * sorts them. Specifically the server splits paths into segments first and then
+ * sorts, putting end-of-segment before any character. In a UTF-8 string
+ * encoding the slash ('/') that denotes the end-of-segment naturally comes
+ * after other characters so the intent here is to encode the path delimiters in
+ * such a way that the resulting strings sort naturally.
+ *
+ * Resource paths are also used for prefix scans so it's important to
+ * distinguish whole segments from any longer segments of which they might be a
+ * prefix. For example, it's important to make it possible to scan documents in
+ * a collection "foo" without encountering documents in a collection "foobar".
+ *
+ * Separate from the concerns about resource path ordering and separation,
+ * On Android, SQLite imposes additional restrictions since it does not handle
+ * keys with embedded NUL bytes particularly well. Rather than change the
+ * implementation we keep the encoding identical to keep the ports similar.
+ *
+ * Taken together this means resource paths when encoded for storage in
+ * IndexedDB have the following characteristics:
+ *
+ *   * Segment separators ("/") sort before everything else.
+ *   * All paths have a trailing separator.
+ *   * NUL bytes do not exist in the output, since IndexedDB doesn't treat them
+ * well.
+ *
+ * Therefore resource paths are encoded into string form using the following
+ * rules:
+ *
+ *   * '\x01' is used as an escape character.
+ *   * Path separators are encoded as "\x01\x01"
+ *   * NUL bytes are encoded as "\x01\x10"
+ *   * '\x01' is encoded as "\x01\x11"
+ *
+ * This encoding leaves some room between path separators and the NUL byte
+ * just in case we decide to support integer document ids after all.
+ *
+ * Note that characters treated specially by the backend ('.', '/', and '~')
+ * are not treated specially here. This class assumes that any unescaping of
+ * resource path strings into actual ResourcePath objects will handle these
+ * characters there.

+/**
+ * An IndexedDB-backed instance of Persistence. Data is stored persistently
+ * across sessions.
+ *
+ * On Web only, the Firestore SDKs support shared access to its persistence
+ * layer. This allows multiple browser tabs to read and write to IndexedDb and
+ * to synchronize state even without network connectivity. Shared access is
+ * currently optional and not enabled unless all clients invoke
+ * `enablePersistence()` with `{synchronizeTabs:true}`.
+ *
+ * In multi-tab mode, if multiple clients are active at the same time, the SDK
+ * will designate one client as the “primary client”. An effort is made to pick
+ * a visible, network-connected and active client, and this client is
+ * responsible for letting other clients know about its presence. The primary
+ * client writes a unique client-generated identifier (the client ID) to
+ * IndexedDb’s “owner” store every 4 seconds. If the primary client fails to
+ * update this entry, another client can acquire the lease and take over as
+ * primary.
+ *
+ * Some persistence operations in the SDK are designated as primary-client only
+ * operations. This includes the acknowledgment of mutations and all updates of
+ * remote documents. The effects of these operations are written to persistence
+ * and then broadcast to other tabs via LocalStorage (see
+ * `WebStorageSharedClientState`), which then refresh their state from
+ * persistence.
+ *
+ * Similarly, the primary client listens to notifications sent by secondary
+ * clients to discover persistence changes written by secondary clients, such as
+ * the addition of new mutations and query targets.
+ *
+ * If multi-tab is not enabled and another tab already obtained the primary
+ * lease, IndexedDbPersistence enters a failed state and all subsequent
+ * operations will automatically fail.
+ *
+ * Additionally, there is an optimization so that when a tab is closed, the
+ * primary lease is released immediately (this is especially important to make
+ * sure that a refreshed tab is able to immediately re-acquire the primary
+ * lease). Unfortunately, IndexedDB cannot be reliably used in window.unload
+ * since it is an asynchronous API. So in addition to attempting to give up the
+ * lease, the leaseholder writes its client ID to a "zombiedClient" entry in
+ * LocalStorage which acts as an indicator that another tab should go ahead and
+ * take the primary lease immediately regardless of the current lease timestamp.
+ *
+ * TODO(b/114226234): Remove `synchronizeTabs` section when multi-tab is no
+ * longer optional.

+ * (Active mutations are those that are enqueued and have not been previously

+ * The LocalStore is responsible for the garbage collection of the documents it
+ * contains. For now, it every doc referenced by a view, the mutation queue, or
+ * the RemoteStore.
+ *
+ * It also maintains the persistence of mapping queries to resume tokens and
+ * target ids. It needs to know this data about queries to properly know what
+ * docs it would be allowed to garbage collect.
+ *
+ * The LocalStore must be able to efficiently execute queries against its local
+ * cache of the documents, to provide the initial set of results before any
+ * remote changes have been received.
+ *
+ * Note: In TypeScript, most methods return Promises since the implementation

+ *
+ * Persistence also exposes an API to create and run PersistenceTransactions
+ * against persistence. All read / write operations must be wrapped in a
+ * transaction. Implementations of PersistenceTransaction / Persistence only
+ * need to guarantee that writes made against the transaction are not made to
+ * durable storage until the transaction resolves its PersistencePromise.
+ * Since memory-only storage components do not alter durable storage, they are
+ * free to ignore the transaction.
+ *
+ * This contract is enough to allow the LocalStore be be written
+ * independently of whether or not the stored state actually is durably
+ * persisted. If persistent storage is enabled, writes are grouped together to
+ * avoid inconsistent state that could cause crashes.
+ *
+ * Concretely, when persistent storage is enabled, the persistent versions of
+ * MutationQueue, RemoteDocumentCache, and others (the mutators) will
+ * defer their writes into a transaction. Once the local store has completed
+ * one logical operation, it commits the transaction.
+ *
+ * When persistent storage is disabled, the non-persistent versions of the
+ * mutators ignore the transaction. This short-cut is allowed because
+ * memory-only storage leaves no state so it cannot be inconsistent.
+ *
+ * This simplifies the implementations of the mutators and allows memory-only
+ * implementations to supplement the persistent ones without requiring any
+ * special dual-store implementation of Persistence. The cost is that the
