Removes a shutdown task from the list using a token returned by runOnShutdown

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

Deletes all commitments whose period ends at or before the given timestamp.

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.

track running futures on shutdown

set to true to get detailed information about all futures that did not complete during shutdown. if set to false, we don't do anything.

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

Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.

Note: you should *not* invoke success on the returned promise but rather use trySuccess. The reason is that the call to success may fail in case of shutdown.

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

Returns, if exists, a list containing all commitments originating from the given participant that overlap the given period. Does not delete them from the queue.

When the period covers a single reconciliation interval, there should be only one such commitment if the counter participant is correct; otherwise, the counter participant is malicious. The method is unaware of reconciliation intervals, however, thus cannot distinguish malicious behavior, and leaves this up to the caller. The caller (who has access to the reconciliation interval duration) should signal malicious behavior by emitting an AcsCommitmentAlarm if the list contains more than one element. Even with possible malicious behavior, the list of commitments might still be useful to the caller, for example if the list contains the expected commitment among all unexpected ones.

However, the period passed to the method can cover several reconciliation intervals (e.g., when the caller participant hasn't heard from the sequencer in a while, and thus did not observe intermediate ticks). But the counter participant might have sent commitments for several reconciliation intervals in the period. Thus, in this case, the method returns a list and there is no malicious behavior.

Returns all commitments whose period ends at or before the given timestamp.

Does not delete them from the queue.

Returns all commitments whose period ends at or after the given timestamp.

Does not delete them from the queue.

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.

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.

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.

Same as runOnShutdown_ but returns a token that allows you to remove the task explicitly from being run using cancelShutdownTask

Register a task to run when shutdown is initiated.

You can use this for example to register tasks that cancel long-running computations, whose termination you can then wait for in "closeAsync".
