* :) * Slight tidy * Remove ServiceBuilderCommand * Remove whitespace * Keep task manager alive for check_block/import_blocks * Pass task_manager to run_until_exit * Make task_manager in run_until_exit and make subcommands async * Change the async_run fn to return a future and task manager * async_run should take a result fn * Apply suggestions from code review Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com> * Fix spaces in export_raw_state Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com>
