/**
 * Construct a Matrix Client. Only directly construct this if you want to use
 * custom modules. Normally, {@link createClient} should be used
 * as it specifies 'sensible' defaults for these modules.
 * @constructor
 * @extends {external:EventEmitter}
 * @extends {module:base-apis~MatrixBaseApis}
 *
 * @param {Object} opts The configuration options for this client.
 * @param {string} opts.baseUrl Required. The base URL to the client-server
 * HTTP API.
 * @param {string} opts.idBaseUrl Optional. The base identity server URL for
 * identity server requests.
 * @param {Function} opts.request Required. The function to invoke for HTTP
 * requests. The value of this property is typically <code>require("request")
 * </code> as it returns a function which meets the required interface. See
 * {@link requestFunction} for more information.
 *
 * @param {string} opts.accessToken The access_token for this user.
 *
 * @param {string} opts.userId The user ID for this user.
 *
 * @param {Object} opts.deviceToImport Device data exported with
 *     "exportDevice" method that must be imported to recreate this device.
 *     Should only be useful for devices with end-to-end crypto enabled.
 *     If provided, opts.deviceId and opts.userId should **NOT** be provided
 *     (they are present in the exported data).
 *
 * @param {string} opts.pickleKey Key used to pickle olm objects or other
 *     sensitive data.
 *
 * @param {IdentityServerProvider} [opts.identityServer]
 * Optional. A provider object with one function `getAccessToken`, which is a
 * callback that returns a Promise<String> of an identity access token to supply
 * with identity requests. If the object is unset, no access token will be
 * supplied.
 * See also https://github.com/vector-im/element-web/issues/10615 which seeks to
 * replace the previous approach of manual access tokens params with this
 * callback throughout the SDK.
 *
 * @param {Object=} opts.store
 *    The data store used for sync data from the homeserver. If not specified,
 *    this client will not store any HTTP responses. The `createClient` helper
 *    will create a default store if needed.
 *
 * @param {module:store/session/webstorage~WebStorageSessionStore} opts.sessionStore
 *    A store to be used for end-to-end crypto session data. Most data has been
 *    migrated out of here to `cryptoStore` instead. If not specified,
 *    end-to-end crypto will be disabled. The `createClient` helper
 *    _will not_ create this store at the moment.
 *
 * @param {module:crypto.store.base~CryptoStore} opts.cryptoStore
 *    A store to be used for end-to-end crypto session data. If not specified,
 *    end-to-end crypto will be disabled. The `createClient` helper will create
 *    a default store if needed.
 *
 * @param {string=} opts.deviceId A unique identifier for this device; used for
 *    tracking things like crypto keys and access tokens.  If not specified,
 *    end-to-end crypto will be disabled.
 *
 * @param {Object} opts.scheduler Optional. The scheduler to use. If not
 * specified, this client will not retry requests on failure. This client
 * will supply its own processing function to
 * {@link module:scheduler~MatrixScheduler#setProcessFunction}.
 *
 * @param {Object} opts.queryParams Optional. Extra query parameters to append
 * to all requests with this client. Useful for application services which require
 * <code>?user_id=</code>.
 *
 * @param {Number=} opts.localTimeoutMs Optional. The default maximum amount of
 * time to wait before timing out HTTP requests. If not specified, there is no timeout.
 *
 * @param {boolean} [opts.useAuthorizationHeader = false] Set to true to use
 * Authorization header instead of query param to send the access token to the server.
 *
 * @param {boolean} [opts.timelineSupport = false] Set to true to enable
 * improved timeline support ({@link
 * module:client~MatrixClient#getEventTimeline getEventTimeline}). It is
 * disabled by default for compatibility with older clients - in particular to
 * maintain support for back-paginating the live timeline after a '/sync'
 * result with a gap.
 *
 * @param {boolean} [opts.unstableClientRelationAggregation = false]
 * Optional. Set to true to enable client-side aggregation of event relations
 * via `EventTimelineSet#getRelationsForEvent`.
 * This feature is currently unstable and the API may change without notice.
 *
 * @param {Array} [opts.verificationMethods] Optional. The verification method
 * that the application can handle.  Each element should be an item from {@link
 * module:crypto~verificationMethods verificationMethods}, or a class that
 * implements the {$link module:crypto/verification/Base verifier interface}.
 *
 * @param {boolean} [opts.forceTURN]
 * Optional. Whether relaying calls through a TURN server should be forced.
 *
 * @param {boolean} [opts.fallbackICEServerAllowed]
 * Optional. Whether to allow a fallback ICE server should be used for negotiating a
 * WebRTC connection if the homeserver doesn't provide any servers. Defaults to false.
 *
 * @param {boolean} [opts.usingExternalCrypto]
 * Optional. Whether to allow sending messages to encrypted rooms when encryption
 * is not available internally within this SDK. This is useful if you are using an external
 * E2E proxy, for example. Defaults to false.
 *
 * @param {object} opts.cryptoCallbacks Optional. Callbacks for crypto and cross-signing.
 *     The cross-signing API is currently UNSTABLE and may change without notice.
 *
 * @param {function} [opts.cryptoCallbacks.getCrossSigningKey]
 * Optional. Function to call when a cross-signing private key is needed.
 * Secure Secret Storage will be used by default if this is unset.
 * Args:
 *    {string} type The type of key needed.  Will be one of "master",
 *      "self_signing", or "user_signing"
 *    {Uint8Array} publicKey The public key matching the expected private key.
 *        This can be passed to checkPrivateKey() along with the private key
 *        in order to check that a given private key matches what is being
 *        requested.
 *   Should return a promise that resolves with the private key as a
 *   UInt8Array or rejects with an error.
 *
 * @param {function} [opts.cryptoCallbacks.saveCrossSigningKeys]
 * Optional. Called when new private keys for cross-signing need to be saved.
 * Secure Secret Storage will be used by default if this is unset.
 * Args:
 *   {object} keys the private keys to save. Map of key name to private key
 *       as a UInt8Array. The getPrivateKey callback above will be called
 *       with the corresponding key name when the keys are required again.
 *
 * @param {function} [opts.cryptoCallbacks.shouldUpgradeDeviceVerifications]
 * Optional. Called when there are device-to-device verifications that can be
 * upgraded into cross-signing verifications.
 * Args:
 *   {object} users The users whose device verifications can be
 *     upgraded to cross-signing verifications.  This will be a map of user IDs
 *     to objects with the properties `devices` (array of the user's devices
 *     that verified their cross-signing key), and `crossSigningInfo` (the
 *     user's cross-signing information)
 * Should return a promise which resolves with an array of the user IDs who
 * should be cross-signed.
 *
 * @param {function} [opts.cryptoCallbacks.getSecretStorageKey]
 * Optional. Function called when an encryption key for secret storage
 *     is required. One or more keys will be described in the keys object.
 *     The callback function should return a promise with an array of:
 *     [<key name>, <UInt8Array private key>] or null if it cannot provide
 *     any of the keys.
 * Args:
 *   {object} keys Information about the keys:
 *       {
 *           keys: {
 *               <key name>: {
 *                   pubkey: {UInt8Array}
 *               }, ...
 *           }
 *       }
 *   {string} name the name of the value we want to read out of SSSS, for UI purposes.
 *
 * @param {function} [opts.cryptoCallbacks.cacheSecretStorageKey]
 * Optional. Function called when a new encryption key for secret storage
 * has been created. This allows the application a chance to cache this key if
 * desired to avoid user prompts.
 * Args:
 *   {string} keyId the ID of the new key
 *   {Uint8Array} key the new private key
 *
 * @param {function} [opts.cryptoCallbacks.onSecretRequested]
 * Optional. Function called when a request for a secret is received from another
 * device.
 * Args:
 *   {string} name The name of the secret being requested.
 *   {string} userId The user ID of the client requesting
 *   {string} deviceId The device ID of the client requesting the secret.
 *   {string} requestId The ID of the request. Used to match a
 *     corresponding `crypto.secrets.request_cancelled`. The request ID will be
 *     unique per sender, device pair.
 *   {DeviceTrustLevel} deviceTrust: The trust status of the device requesting
 *     the secret as returned by {@link module:client~MatrixClient#checkDeviceTrust}.

 * to PREPARED. Starts listening for live updates rather than catching up.
 *
 * <li><code>SYNCING -> RECONNECTING</code> : Occurs when the live update fails.
 *
 * <li><code>RECONNECTING -> RECONNECTING</code> : Can occur if the update calls
 * continue to fail, but the keepalive calls (to /versions) succeed.
 *
 * <li><code>RECONNECTING -> ERROR</code> : Occurs when the keepalive call also fails
 *
 * <li><code>ERROR -> SYNCING</code> : Occurs when the client has performed a

 * <li><code>ERROR -> ERROR</code> : Occurs when the client has failed to keepalive
 * for a second time or more.</li>
 *
 * <li><code>SYNCING -> SYNCING</code> : Occurs when the client has performed a live

/**
 * Abstracts the logic used to drive the interactive auth process.
 *
 * <p>Components implementing an interactive auth flow should instantiate one of
 * these, passing in the necessary callbacks to the constructor. They should
 * then call attemptAuth, which will return a promise which will resolve or
 * reject when the interactive-auth process completes.
 *
 * <p>Meanwhile, calls will be made to the startAuthStage and doRequest
 * callbacks, and information gathered from the user can be submitted with
 * submitAuthDict.
 *
 * @constructor
 * @alias module:interactive-auth
 *
 * @param {object} opts  options object
 *
 * @param {object} opts.matrixClient A matrix client to use for the auth process
 *
 * @param {object?} opts.authData error response from the last request. If
 *    null, a request will be made with no auth before starting.
 *
 * @param {function(object?): Promise} opts.doRequest
 *     called with the new auth dict to submit the request. Also passes a
 *     second deprecated arg which is a flag set to true if this request
 *     is a background request. The busyChanged callback should be used
 *     instead of the backfround flag. Should return a promise which resolves
 *     to the successful response or rejects with a MatrixError.
 *
 * @param {function(bool): Promise} opts.busyChanged
 *     called whenever the interactive auth logic becomes busy submitting
 *     information provided by the user or finsihes. After this has been
 *     called with true the UI should indicate that a request is in progress
 *     until it is called again with false.
 *
 * @param {function(string, object?)} opts.stateUpdated
 *     called when the status of the UI auth changes, ie. when the state of
 *     an auth stage changes of when the auth flow moves to a new stage.
 *     The arguments are: the login type (eg m.login.password); and an object
 *     which is either an error or an informational object specific to the
 *     login type. If the 'errcode' key is defined, the object is an error,
 *     and has keys:
 *         errcode: string, the textual error code, eg. M_UNKNOWN
 *         error: string, human readable string describing the error
 *
 *     The login type specific objects are as follows:
 *         m.login.email.identity:
 *          * emailSid: string, the sid of the active email auth session
 *
 * @param {object?} opts.inputs Inputs provided by the user and used by different
 *     stages of the auto process. The inputs provided will affect what flow is chosen.
 *
 * @param {string?} opts.inputs.emailAddress An email address. If supplied, a flow
 *     using email verification will be chosen.
 *
 * @param {string?} opts.inputs.phoneCountry An ISO two letter country code. Gives
 *     the country that opts.phoneNumber should be resolved relative to.
 *
 * @param {string?} opts.inputs.phoneNumber A phone number. If supplied, a flow
 *     using phone number validation will be chosen.
 *
 * @param {string?} opts.sessionId If resuming an existing interactive auth session,
 *     the sessionId of that session.
 *
 * @param {string?} opts.clientSecret If resuming an existing interactive auth session,
 *     the client secret for that session
 *
 * @param {string?} opts.emailSid If returning from having completed m.login.email.identity
 *     auth, the sid for the email verification session.
 *
 * @param {function?} opts.requestEmailToken A function that takes the email address (string),
 *     clientSecret (string), attempt number (int) and sessionId (string) and calls the
 *     relevant requestToken function and returns the promise returned by that function.
 *     If the resulting promise rejects, the rejection will propagate through to the
 *     attemptAuth promise.

 * Construct a set of EventTimeline objects, typically on behalf of a given

 * of filtering.  The global notification list is also an EventTimelineSet, but
 * lacks a room.
 *
 * <p>This is an ordered sequence of timelines, which may or may not
 * be continuous. Each timeline lists a series of events, as well as tracking
 * the room state at the start and the end of the timeline (if appropriate).
 * It also tracks forward and backward pagination tokens, as well as containing
 * links to the next timeline in the sequence.
 *
 * <p>There is one special timeline - the 'live' timeline, which represents the
 * timeline to which events are being added in real-time as they are received
 * from the /sync API. Note that you should not retain references to this
 * timeline - even if it is the current timeline right now, it may not remain
 * so if the server gives us a timeline gap in /sync.
 *
 * <p>In order that we can find events from their ids later, we also maintain a
 * map from event_id to timeline and index.

  // illustrates some of the corner-cases.
  //
  // Let's say we start by knowing about four timelines. timeline3 and
  // timeline4 are neighbours:
  //
  //    timeline1    timeline2    timeline3    timeline4
  //      [M]          [P]          [S] <------> [T]
  //
  // Now we paginate timeline1, and get the following events from the server:
  // [M, N, P, R, S, T, U].
  //
  // 1. First, we ignore event M, since we already know about it.
  //
  // 2. Next, we append N to timeline 1.
  //
  // 3. Next, we don't add event P, since we already know about it,
  //    but we do link together the timelines. We now have:
  //
  //    timeline1    timeline2    timeline3    timeline4
  //      [M, N] <---> [P]          [S] <------> [T]
  //
  // 4. Now we add event R to timeline2:
  //
  //    timeline1    timeline2    timeline3    timeline4
  //      [M, N] <---> [P, R]       [S] <------> [T]
  //
  //    Note that we have switched the timeline we are working on from
  //    timeline1 to timeline2.
  //
  // 5. We ignore event S, but again join the timelines:
  //
  //    timeline1    timeline2    timeline3    timeline4
  //      [M, N] <---> [P, R] <---> [S] <------> [T]
  //
  // 6. We ignore event T, and the timelines are already joined, so there
  //    is nothing to do.
  //
  // 7. Finally, we add event U to timeline4:
  //
  //    timeline1    timeline2    timeline3    timeline4
  //      [M, N] <---> [P, R] <---> [S] <------> [T, U]
  //
  // The important thing to note in the above is what happened when we
  // already knew about a given event:
  //
  //   - if it was appropriate, we joined up the timelines (steps 3, 5).
  //   - in any case, we started adding further events to the timeline which
  //       contained the event we knew about (steps 3, 5, 6).
  //
  //
  // So much for adding events to the timeline. But what do we want to do
  // with the pagination token?
  //
  // In the case above, we will be given a pagination token which tells us how to
  // get events beyond 'U' - in this case, it makes sense to store this
  // against timeline4. But what if timeline4 already had 'U' and beyond? in
  // that case, our best bet is to throw away the pagination token we were
  // given and stick with whatever token timeline4 had previously. In short,
  // we want to only store the pagination token if the last event we receive
  // is one we didn't previously know about.
  //
  // We make an exception for this if it turns out that we already knew about
  // *all* of the events, and we weren't able to join up any timelines. When
  // that happens, it means our existing pagination token is faulty, since it
  // is only telling us what we already know. Rather than repeatedly
  // paginating with the same token, we might as well use the new pagination
  // token in the hope that we eventually work our way out of the mess.

/**
 * Construct room state.
 *
 * Room State represents the state of the room at a given point.
 * It can be mutated by adding state events to it.
 * There are two types of room member associated with a state event:
 * normal member objects (accessed via getMember/getMembers) which mutate
 * with the state to represent the current state of that room/user, eg.
 * the object returned by getMember('@bob:example.com') will mutate to
 * get a different display name if Bob later changes his display name
 * in the room.
 * There are also 'sentinel' members (accessed via getSentinelMember).
 * These also represent the state of room members at the point in time
 * represented by the RoomState object, but unlike objects from getMember,
 * sentinel objects will always represent the room state as at the time
 * getSentinelMember was called, so if Bob subsequently changes his display
 * name, a room member object previously acquired with getSentinelMember
 * will still have his old display name. Calling getSentinelMember again
 * after the display name change will return a new RoomMember object
 * with Bob's new display name.
 *
 * @constructor
 * @param {?string} roomId Optional. The ID of the room which has this state.
 * If none is specified it just tracks paginationTokens, useful for notifTimelineSet
 * @param {?object} oobMemberFlags Optional. The state of loading out of bound members.
 * As the timeline might get reset while they are loading, this state needs to be inherited
 * and shared when the room state is cloned for the new timeline.
 * This should only be passed from clone.
 * @prop {Object.<string, RoomMember>} members The room member dictionary, keyed
 * on the user's ID.
 * @prop {Object.<string, Object.<string, MatrixEvent>>} events The state
 * events dictionary, keyed on the event type and then the state_key value.
 * @prop {string} paginationToken The pagination token for this state.

 * SError.  Named arguments to this function:
 *
 *     strict		force strict interpretation of sprintf arguments, even
 *     			if the options in "argv" don't say so
 *
 *     argv		error's constructor arguments, which are to be
 *     			interpreted as described in README.md.  For quick
 *     			reference, "argv" has one of the following forms:
 *
 *          [ sprintf_args... ]           (argv[0] is a string)
 *          [ cause, sprintf_args... ]    (argv[0] is an Error)
 *          [ options, sprintf_args... ]  (argv[0] is an object)
 *
 * This function normalizes these forms, producing an object with the following
 * properties:
 *
 *    options           equivalent to "options" in third form.  This will never
 *    			be a direct reference to what the caller passed in
 *    			(i.e., it may be a shallow copy), so it can be freely
 *    			modified.
 *
 *    shortmessage      result of sprintf(sprintf_args), taking options.strict
 *    			into account as described in README.md.

	 * values to be processed by the "%s" specifier.  The value passed to
	 * extsprintf must actually be a string or something convertible to a
	 * String using .toString().  Passing other values (notably "null" and
	 * "undefined") is considered a programmer error.  The assumption is
	 * that if you actually want to print the string "null" or "undefined",
	 * then that's easy to do that when you're calling extsprintf; on the
	 * other hand, if you did NOT want that (i.e., there's actually a bug
	 * where the program assumes some variable is non-null and tries to
	 * print it, which might happen when constructing a packet or file in
	 * some specific format), then it's better to stop immediately than
	 * produce bogus output.
	 *
	 * However, sometimes the bug is only in the code calling VError, and a
	 * programmer might prefer to have the error message contain "null" or
	 * "undefined" rather than have the bug in the error path crash the
	 * program (making the first bug harder to identify).  For that reason,
	 * by default VError converts "null" or "undefined" arguments to their
	 * string representations and passes those to extsprintf.  Programmers
	 * desiring the strict behavior can use the SError class or pass the
	 * "strict" option to the VError constructor.
