class SendTracker extends NamedLogging with FlagCloseableAsync with AutoCloseable

When a we make a send request to the sequencer it will not be sequenced until some point in the future and may not be sequenced at all. To track a request call send with the messageId and max-sequencing-time of the request, the tracker then observes sequenced events and will notify the provided handler whether the send times out. For aggregatable submission requests, the send tracker notifies the handler of successful sequencing of the submission request, not of successful delivery of the envelopes when the com.digitalasset.canton.sequencing.protocol.AggregationRule.threshold has been reached. In fact, there is no notification of whether the threshold was reached before the max sequencing time.

    Cancels a pending send without notifying any callers of the result.

    Cancels a pending send without notifying any callers of the result. Should only be used if the send operation itself fails and the transport returns an error indicating that the send will never be sequenced. The SequencerClient should then call cancel to immediately allow retries with the same message-id and then propagate the send error to the caller.

    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    DO NOT CALL this.close as part of f, because it will result in a deadlock.

    returns

    scala.None$ if a shutdown has been initiated. Otherwise the result of the task.

    Provide the latest sequenced events to update the send tracker

    Provide the latest sequenced events to update the send tracker

    Callers must not call this concurrently and it is assumed that it is called with sequenced events in order of sequencing. On receiving an event it will perform the following steps in order:

    1. If the event is a Deliver or DeliverError from a send that is being tracked it will stop tracking this message id. This allows using the message-id for new sends. 2. Checks for any pending sends that have a max-sequencing-time that is less than the timestamp of this event. These events have timed out and a correct sequencer implementation will no longer sequence any events for this send. The callback of the pending event will be called with the outcome result.

    The operations performed by update are not atomic, if an error is encountered midway through processing an event then a subsequent replay will cause operations that still have pending sends stored to be retried.
