classmethod get_root_id(context, stack_id)[source]
classmethod get_status(context, stack_id)[source]

Return action and status for the given stack.

identifier()[source]

Return an identifier for this stack.

classmethod persist_state_and_release_lock(context, stack_id, engine_id, values)[source]
refresh()[source]
classmethod select_and_update(context, stack_id, values, exp_trvsl=None)[source]

Update the stack by selecting on traversal ID.

Uses UPDATE … WHERE (compare and swap) to catch any concurrent update problem.

If the stack is found with given traversal, it is updated.

If there occurs a race while updating, only one will succeed and other will get return value of False.

tags
update_and_save(values)[source]
classmethod update_by_id(context, stack_id, values)[source]

Update and return (boolean) if it was updated.

Note: the underlying stack_update filters by current_traversal and stack_id.
