Cannot use RoutingModel routing status flags anymore

[RaphaelTlse]

What version of OR-Tools and what language are you using?
9.12.4544
Language: Python

Which solver are you using (e.g. CP-SAT, Routing Solver, GLOP, BOP, Gurobi)
Routing Solver

What operating system (Linux, Windows, ...) and version?
Windows 11

What did you do?
Steps to reproduce the behavior:
With version 9.12.4544: Attempt to access ortools.constraint_solver.pywrapcp.RoutingModel.ROUTING_SUCCESS or any other flag

What did you expect to see
With version 9.11.4210: Getting the routing status

What did you see instead?
With version 9.12.4544: AttributeError: type object 'RoutingModel' has no attribute 'ROUTING_SUCCESS'

I was not able to identify the reason and nature of this change, what is the new expected process to access the routing status in the new version?

Indeed, all RoutingModel enums have been removed in favor of the protobuf enums. This removed duplication.

so the enum is available as routing_enums_pb2.RoutingSearchStatus.ROUTING_SUCCESS

We will update the release notes

FYI

or-tools/ortools/constraint_solver/routing.h

Lines 1440 to 1441 in b8e881f

	/// Returns the current status of the routing model.
	RoutingSearchStatus::Value status() const { return status_; }

or-tools/ortools/constraint_solver/routing_enums.proto

Lines 149 to 171 in b8e881f

	// Used by `RoutingModel` to report the status of the search for a solution.
	message RoutingSearchStatus {
	enum Value {
	// Problem not solved yet (before calling RoutingModel::Solve()).
	ROUTING_NOT_SOLVED = 0;
	// Problem solved successfully after calling RoutingModel::Solve().
	ROUTING_SUCCESS = 1;
	// Problem solved successfully after calling RoutingModel::Solve(), except
	// that a local optimum has not been reached. Leaving more time would allow
	// improving the solution.
	ROUTING_PARTIAL_SUCCESS_LOCAL_OPTIMUM_NOT_REACHED = 2;
	// No solution found to the problem after calling RoutingModel::Solve().
	ROUTING_FAIL = 3;
	// Time limit reached before finding a solution with RoutingModel::Solve().
	ROUTING_FAIL_TIMEOUT = 4;
	// Model, model parameters or flags are not valid.
	ROUTING_INVALID = 5;
	// Problem proven to be infeasible.
	ROUTING_INFEASIBLE = 6;
	// Problem has been solved to optimality.
	ROUTING_OPTIMAL = 7;
	}
	}

Still remain

or-tools/ortools/constraint_solver/routing.h

Lines 254 to 264 in b8e881f

	class OR_DLL RoutingModel {
	public:
	/// Types of precedence policy applied to pickup and delivery pairs.
	enum PickupAndDeliveryPolicy {
	/// Any precedence is accepted.
	PICKUP_AND_DELIVERY_NO_ORDER,
	/// Deliveries must be performed in reverse order of pickups.
	PICKUP_AND_DELIVERY_LIFO,
	/// Deliveries must be performed in the same order as pickups.
	PICKUP_AND_DELIVERY_FIFO
	};
