| 4 | Subject: [PATCH] tests: wait some more before analysing traces or starting |
| 5 | tracing |
| 6 | |
| 7 | Otherwise, there are sporadic race failures where lttng tracing |
| 8 | is stopped before all expected events are collected or is started too soon, e.g.: |
| 9 | |
| 10 | PASS: tools/tracker/test_event_tracker 205 - Traced application stopped. |
| 11 | PASS: tools/tracker/test_event_tracker 206 - Stop lttng tracing for session |
| 12 | PASS: tools/tracker/test_event_tracker 207 - Destroy session tracker |
| 13 | FAIL: tools/tracker/test_event_tracker 208 - Validate empty trace |
| 14 | |
| 15 | PASS: ust/namespaces/test_ns_contexts_change 42 - Stop lttng tracing for session mnt_ns |
| 16 | PASS: ust/namespaces/test_ns_contexts_change 43 - Destroy session mnt_ns |
| 17 | PASS: ust/namespaces/test_ns_contexts_change 44 - Wait after kill session daemon |
| 18 | PASS: ust/namespaces/test_ns_contexts_change 45 - Validate trace for event mnt_ns = 4026531840, 1000 events |
| 19 | PASS: ust/namespaces/test_ns_contexts_change 46 - Read a total of 1000 events, expected 1000 |
| 20 | PASS: ust/namespaces/test_ns_contexts_change 47 - Validate trace for event mnt_ns = 4026532303, 233 events |
| 21 | FAIL: ust/namespaces/test_ns_contexts_change 48 - Read a total of 233 events, expected 1000 |
| 22 | |
| 23 | This is a hack; issue should be fixed upstream with explicit syncs. |
| 24 | It has been reported here: https://bugs.lttng.org/issues/1217 |
| 25 | |
| 26 | Upstream-Status: Inappropriate [needs a real fix] |
