Untested example, and my python skills are not the greatest, so treat this as pseudocode. :) ```python def wait_for(action, timeout, predicate_transform = lambda x: x, check_period = 1): start_time = time.perf_counter() while True: result = action() if predicate_transform(result): return (True, result) time.sleep(check_period) if timeout_seconds < (time.perf_counter() - start_time): break return (False, None) (happened, _) = wait_for(lambda: self.__get_blob_and_snapshot_count() == blob_and_snapshot_count, timeout_seconds) # and the more complex example def get_logs(): logging.info('Waiting for app-logs `%s` in container `%s`', log_entry, container_name) return self.get_app_log(container_name) def predicate(x): (status, logs) = x return logs is not None or status == 'exited' (happened, (status, logs)) = wait_for(get_logs, timeout_seconds, predicate) if not happened or status == 'exited': return False # ... ``` -- This is an automated message from the Apache Git Service.
