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.

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.

TODO(#16601) Make this method private once PerformUnlessClosing doesn't need it any more

Retry policy to retry once for authentication failures to allow re-authentication and optionally retry when unavailable.

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.

Sends a signed submission request to the sequencer. If we failed to make the request, an error will be returned. If the sequencer accepted (or may have accepted) the request this call will return successfully.

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 f only if the component is not yet closing. If so, the component will delay releasing its resources until f has completed (as defined by the com.digitalasset.canton.util.Thereafter instance) or the synchronizeWithClosingPatience has elapsed.

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.

Convenience method for synchronizing on Futures instead of FutureUnlessShutdowns. Equivalent to

synchronizeWithClosing(name)(FutureUnlessShutdown.outcomeF(f))

Runs the computation f only if the component is not yet closing. If so, the component will delay releasing its resources until f has finished or the synchronizeWithClosingPatience has elapsed.

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.

Runs the computation f only if the component is not yet closing. If so, the component will delay releasing its resources until f has completed (as defined by the com.digitalasset.canton.util.Thereafter instance) or the synchronizeWithClosingPatience has elapsed.

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.

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.
