21 | * @file dht/test_dht_twopeer_get_put.c | ||
22 | * @brief base testcase for testing DHT service with | ||
23 | * two running peers. | ||
24 | * | ||
25 | * This testcase starts peers using the GNUNET_TESTING_daemons_start | ||
26 | * function call. On peer start, connects to the peers DHT service | ||
27 | * by calling GNUNET_DHT_connected. Once notified about all peers | ||
28 | * being started (by the peers_started_callback function), calls | ||
29 | * GNUNET_TESTING_connect_topology, which connects the peers in a | ||
30 | * "straight line" topology. On notification that all peers have | ||
31 | * been properly connected, calls the do_get function which initiates | ||
32 | * a GNUNET_DHT_get from the *second* peer. Once the GNUNET_DHT_get | ||
33 | * function starts, runs the do_put function to insert data at the first peer. | ||
34 | * If the GET is successful, schedules finish_testing | ||
35 | * to stop the test and shut down peers. If GET is unsuccessful | ||
36 | * after GET_TIMEOUT seconds, prints an error message and shuts down | ||
37 | * the peers. | ||
