class InFlightSubmissionTracker extends FlagCloseable with NamedLogging

Tracker for in-flight submissions backed by the com.digitalasset.canton.participant.store.InFlightSubmissionStore.

A submission is in flight if it is in the com.digitalasset.canton.participant.store.InFlightSubmissionStore. The tracker registers a submission before the com.digitalasset.canton.sequencing.protocol.SubmissionRequest is sent to the com.digitalasset.canton.sequencing.client.SequencerClient of a domain. After the corresponding event has been published into the com.digitalasset.canton.participant.store.MultiDomainEventLog state updates, the submission will be removed from the com.digitalasset.canton.participant.store.InFlightSubmissionStore again. This happens normally as part of request processing after phase 7. If the submission has not been sequenced by the specified com.digitalasset.canton.participant.protocol.submission.UnsequencedSubmission.timeout, say because the submission was lost on the way to the sequencer, the participant generates an appropriate update because the submission will never reach request processing. The latter must work even if the participant crashes (if run with persistence).

    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.

    Deletes the published, sequenced in-flight submissions with sequencing timestamps up to the given bound and informs the CommandDeduplicator about the published events.

    upToInclusive

    Upper bound on the sequencing time of the submissions to be recovered. The com.digitalasset.canton.participant.sync.LedgerSyncEvents for all sequenced submissions up to this bound must have been published to the com.digitalasset.canton.participant.store.MultiDomainEventLog. The com.digitalasset.canton.participant.sync.LedgerSyncEvents for all sequenced submissions in the com.digitalasset.canton.participant.store.InFlightSubmissionStore must not yet have been pruned from the com.digitalasset.canton.participant.store.MultiDomainEventLog.

  46. def recoverPublishedTimelyRejections(domains: Seq[DomainId])(implicit traceContext: TraceContext): Future[Unit]

  47. def register(submission: InFlightSubmission[UnsequencedSubmission], deduplicationPeriod: DeduplicationPeriod): EitherT[FutureUnlessShutdown, InFlightSubmissionTrackerError, Either[DeduplicationFailed, DeduplicationOffset]]

    Registers the given submission as being in flight and unsequenced unless there already is an in-flight submission for the same change ID or the timeout has already elapsed.
