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:

removed_IDs

Parameters:

inactive_IDs (List[int]) –
start_times (Dict[int, str]) –
end_times (Dict[int, str]) –

property user_cache_hostname_dir: Path#: The hostname-scoped app cache directory.

property user_data_dir: Path#: The user’s data directory.

property user_data_hostname_dir: Path#

The directory for holding user data.

We segregate by hostname to account for the case where multiple machines might use the same shared file system.

property user_runtime_dir: Path#: The user’s temporary runtime directory.

version#: The version of the application.

workflows_dir#: Directory for workflows.
