update_known_subs_file(inactive_IDs, start_times, end_times)

Update submission records in the known-submission file.

Note

We aim for atomicity to help with the scenario where a new workflow submission is adding itself to the file at the same time as we have decided an existing workflow should no longer be part of this file. Ideally, such a scenario should not arise because both operations should only ever be interactively initiated by the single user (Workflow.submit and App.get_known_submissions). If this operation is atomic, then at least the known-submissions file should be left in a usable (but inaccurate) state.

Returns:

List of local IDs removed from the known-submissions file due to the maximum number of recent workflows to store being exceeded.

Return type:

list[int]
