Blocks until all earlier tasks have completed and then prevents further tasks from being run.

Completes the given reassignment with the given tsCompletion. Completion appears atomic to reassignment lookups that go through the cache.

Find utility to look for in-flight reassignments. Reassignments are ordered by the tuple (request timestamp, source synchronizer id), ie reassignments are ordered by request timestamps and ties are broken with lexicographic ordering on synchronizer ids.

The ordering here has been chosen to allow a participant to fetch all the pending reassignments. The ordering has to be consistent accross calls and uniquely identify a pending reassignment, but is otherwise arbitrary.

Queries the reassignment ids for the given contract ids. Optional filtering by unassignment and completion (assignment) timestamps, and by source synchronizer.

Find utility to look for the earliest incomplete reassignment w.r.t. the ledger end. If an incomplete reassignment exists, the method returns the global offset of the incomplete reassignment for either the unassignment or the assignment, whichever of these is not null, the reassignment id and the target synchronizer id. It returns None if there is no incomplete reassignment (either because all reassignments are complete or are in-flight, or because there are no reassignments), or the reassignment table is empty.

unassignment/assignment global offsets will be updated upon publication on Ledger API Indexer, when the global offset is assigned to the event. In order to avoid race conditions, the multi-synchronizer event log will wait for the calls to ReassignmentStore.addReassignmentOffsets to complete before updating ledger end. Hence, we don't need additional synchronization here and we can directly query the store.

Check whether we're closing. Susceptible to race conditions; unless you're using this as a flag to the retry lib or you really know what you're doing, prefer performUnlessClosing and friends.

Set this to true to get detailed information about all futures that did not complete during shutdown.

Looks up the given in-flight reassignment and returns the data associated with the reassignment.

How often to poll to check that all tasks have completed.

Blocks until all earlier tasks have completed and then prevents further tasks from being run.

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. DO NOT PUT retries, especially indefinite ones, inside f.

Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down. The shutdown will only begin after etf completes, but other tasks may execute concurrently with etf, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingF). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of etf, because it will result in a deadlock. DO NOT PUT retries, especially indefinite ones, inside f.

Use this method if closing/shutdown of the object should wait for asynchronous computation to finish too.

Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. 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 (performUnlessClosing 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. DO NOT PUT retries, especially indefinite ones, inside f.

Schedules the given task to be run upon closing.

Register a task to run when closing is initiated, or run it immediately if closing is already ongoing. Unlike runOnClose, this method does not guarantee that this task will have run by the time the LifeCycleManager's closeAsync method completes or AutoCloseable's close returns. This is because the task is run immediately if the component has already been closed.

Variant of runOnOrAfterClose that does not return a com.digitalasset.canton.lifecycle.LifeCycleRegistrationHandle.

Runs the computation fa unless isClosing returns true.

This method does not delay the closing while fa is running, unlike the methods in HasSynchronizeWithClosing. Accordingly, this method is useful for intermittent checks whether the result of the computation is still relevant.
