22 | * @file testbed/gnunet-cmds-helper.c | ||
23 | * @brief Helper binary that is started from a remote interpreter loop to start | ||
24 | * a local interpreter loop. | ||
25 | * | ||
26 | * This helper monitors for three termination events. They are: (1)The | ||
27 | * stdin of the helper is closed for reading; (2)the helper received | ||
28 | * SIGTERM/SIGINT; (3)the local loop crashed. In case of events 1 and 2 | ||
29 | * the helper kills the interpreter loop. When the interpreter loop | ||
30 | * crashed (event 3), the helper should send a SIGTERM to its own process | ||
31 | * group; this behaviour will help terminate any child processes the loop | ||
32 | * has started and prevents them from leaking and running forever. | ||
