Distribute an acknowledgement request. Results in a com.digitalasset.canton.synchronizer.block.RawLedgerBlock.RawBlockEvent.Acknowledgment.

Services for administering the ledger driver. These services will be exposed on the sequencer node's admin API endpoint.

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.

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

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.

Send a submission request. Results in a com.digitalasset.canton.synchronizer.block.RawLedgerBlock.RawBlockEvent.Send.

Delivers a stream of blocks starting with firstBlockHeight (if specified in the factory call) or the first block serveable. Block heights must be consecutive.

If firstBlockHeight refers to a block whose sequencing number the sequencer node has not yet observed, returns a source that will eventually serve that block when it gets created.

Must succeed if an earlier call to subscribe delivered a block with height firstBlockHeight unless the block has been pruned in between, in which case it fails

This method will be called only once, so implementations do not have to try to create separate sources on every call to this method. It is acceptable to for the driver to have one internal source and just return it here.

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.
