Enumeration Type Documentation

m0_net_test_service_state

enum m0_net_test_service_state

Service state

Enumerator
M0_NET_TEST_SERVICE_UNINITIALIZED	Service is not initialized
M0_NET_TEST_SERVICE_READY	Service is ready to handle commands
M0_NET_TEST_SERVICE_FINISHED	Service was finished. Can be set by service operations
M0_NET_TEST_SERVICE_FAILED	Service was failed. Can be set by service operations
M0_NET_TEST_SERVICE_NR	Number of service states

Function Documentation

m0_net_test_service_cmd_handle()

int m0_net_test_service_cmd_handle	(	struct m0_net_test_service *	svc,
		struct m0_net_test_cmd *	cmd,
		struct m0_net_test_cmd *	reply
	)

Handle command and fill reply

Precondition

m0_net_test_service_invariant(svc)

Postcondition

m0_net_test_service_invariant(svc)

Definition at line 121 of file service.c.

Here is the call graph for this function:

Here is the caller graph for this function:

m0_net_test_service_fini()

void m0_net_test_service_fini

(

struct m0_net_test_service *

svc

)

Finalize test service. Service can be finalized from any state except M0_NET_TEST_SERVICE_UNINITIALIZED.

Precondition

m0_net_test_service_invariant(svc)

(svc->nts_state != M0_NET_TEST_SERVICE_UNINITIALIZED)

Postcondition

m0_net_test_service_invariant(svc)

Definition at line 88 of file service.c.

Here is the call graph for this function:

Here is the caller graph for this function:

m0_net_test_service_init()

int m0_net_test_service_init	(	struct m0_net_test_service *	svc,
		struct m0_net_test_service_ops *	ops
	)

Initialize test service. Typical pattern to use test service:

m0_net_test_service_init();
while (state != FAILED && state != FINISHED) {
        command_was_received = try_to_receive_command();
        if (command_was_received)
        m0_net_test_service_cmd_handle(received_command);
        else
        m0_net_test_service_step();
}
m0_net_test_service_fini();

Note

Service state will not be changed if ops->ntso_init returns non-zero result and will be changed to M0_NET_TEST_SERVICE_READY otherwise.

Parameters

svc	Test service
ops	Service operations

ergo(result == 0, m0_net_test_service_invariant(svc))

	)

Change service state. Can be called from service ops.
