Acknowledge that we have successfully processed all events up to and including the given timestamp. The client should then never subscribe for events from before this point.

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

closeAsync asynchronously releases resources held by a future

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.

Revoke all the authentication tokens on this sequencer and close the connection.

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.

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.

We're replaying sends so shouldn't allow the app to send any new ones

Create a single subscription to read events from the Sequencer for this member starting from the counter defined in the request. The transport is not expected to provide retries of subscriptions.

Create a single subscription to read events from the Sequencer for this member starting from the counter defined in the request. Transports are currently responsible for calling the supplied handler. The handler must not be called concurrently and must receive events in-order. If the handler fails with an exception the subscription should close with a com.digitalasset.canton.sequencing.client.SubscriptionCloseReason.HandlerError. If the subscription fails for a technical reason it should close with a com.digitalasset.canton.sequencing.client.SubscriptionCloseReason.SubscriptionError. The transport is not expected to provide retries of subscriptions.

The transport can decide which errors will cause the sequencer client to not try to reestablish a subscription

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.
