| 1 | Daemon tracing test |
| 2 | ------------------- |
| 3 | |
| 4 | This test checks if tracing works correctly in a child process created by a |
| 5 | call to daemon(). |
| 6 | |
| 7 | DESCRIPTION |
| 8 | ----------- |
| 9 | |
| 10 | A session daemon is launched if none are found to be running. The test_daemon |
| 11 | script then creates a session, enables all events from the userspace domain, |
| 12 | starts the session and launches the daemon binary. |
| 13 | |
| 14 | The daemon binary, in turn, triggers tracepoints both from the original and |
| 15 | resulting daemon process. |
| 16 | |
| 17 | The test_daemon script then parses the resulting trace and ensures that the |
| 18 | events were correctly recorded and were logged with the right PIDs. |
