Issue 135: Prune scheduling issue

[davramov]

This PR addresses issue #135, where a flow that uses the prune controller "completes" before pruning is actually scheduled, resulting in a Execution was cancelled by the runtime environment.

Now in GlobusPruneController, I have wrapped the schedule_prefect_flow call that will block until the future result is returned, to ensure that the flow does not complete until pruning is scheduled:

                future = schedule_prefect_flow.submit(
                    deployment_name="prune_globus_endpoint/prune_globus_endpoint",
                    flow_run_name=flow_name,
                    parameters={
                        "relative_path": file_path,
                        "source_endpoint": source_endpoint,
                        "check_endpoint": check_endpoint,
                        # "config": self.config
                    },
                    duration_from_now=days_from_now,
                )
                future.result()

Pull request overview

Fixes Prefect prune scheduling race (Issue #135) by ensuring the prune-scheduling task fully completes (and the scheduled flow run is created) before the calling flow/task can finish, preventing “Execution was cancelled by the runtime environment” from aborting scheduling.

Changes:

• Block on the schedule_prefect_flow.submit(...) future in GlobusPruneController.prune() via future.result() to guarantee scheduling completes.
• Use Prefect’s run logger (get_run_logger) in FileSystemPruneController.prune() for Prefect-context logging.
