Created attachment 4799 [details] ptest regression report Following ptest is failing in current release(3.2.4 rc1) while passing in previous release(3.2.3 rc1): ptestresult.lttng-tools.tools/tracker/test_event_tracker_217_-_Validate_empty_trace Regression is performed on ptest results for qemux86-64. ptest Results for current release: https://autobuilder.yocto.io/pub/releases/yocto-3.2.4.rc1/testresults/qemux86-64-ptest/ ptest results for previous release: https://autobuilder.yocto.io/pub/releases/yocto-3.2.3.rc1/testresults/qemux86-64-ptest/
I reran this on the autobuilder: https://autobuilder.yoctoproject.org/typhoon/#/builders/81/builds/2083 which "passed" but shows some failures: AssertionError: Failed ptests: {'lttng-tools': ['tools/exclusion/test_exclusion_169_-_Excluded_event_"tp:tptest1"_was_found_in_trace!', 'tools/save-load/test_load_22_-_Destroy_session_tracker_legacy_all', 'tools/save-load/test_load_23_-_Destroy_session_tracker_legacy_none', 'tools/save-load/test_load_24_-_Destroy_session_tracker_legacy_selective', 'tools/tracker/test_event_tracker_208_-_Failed_to_parse_trace', 'tools/tracker/test_event_tracker_217_-_Validate_empty_trace', 'tools/tracker/test_event_tracker_250_-_Failed_to_parse_trace', 'tools/tracker/test_event_tracker_259_-_Validate_empty_trace', 'ust/namespaces/test_ns_contexts_change_15_-_Validate_trace_for_event_cgroup_ns_=_4026532234', 'ust/namespaces/test_ns_contexts_change_16_-_Read_a_total_of_0_events,_expected_1000', 'ust/namespaces/test_ns_contexts_change_31_-_Validate_trace_for_event_ipc_ns_=_4026532233', 'ust/namespaces/test_ns_contexts_change_32_-_Read_a_total_of_0_events,_expected_1000', 'ust/namespaces/test_ns_contexts_change_47_-_Validate_trace_for_event_mnt_ns_=_4026532234', 'ust/namespaces/test_ns_contexts_change_48_-_Read_a_total_of_0_events,_expected_1000', 'ust/namespaces/test_ns_contexts_change_63_-_Validate_trace_for_event_net_ns_=_4026532237', 'ust/namespaces/test_ns_contexts_change_64_-_Read_a_total_of_0_events,_expected_1000', 'ust/namespaces/test_ns_contexts_change_79_-_Validate_trace_for_event_uts_ns_=_4026532234', 'ust/namespaces/test_ns_contexts_change_80_-_Read_a_total_of_0_events,_expected_1000'], 'pango': ['pango/test-layout.test']} The results logs are at: http://autobuilder.yocto.io/pub/non-release/20210512-19/testresults/qemux86-64-ptest/lttng-tools.log I looked back at the 3.2 baseline: http://downloads.yoctoproject.org/releases/yocto/yocto-3.2/testresults/testresult-report.txt ltpresult.syscalls.ptrace08 testseries | result_id : qemux86-64-ptest | runtime_core-image-sato-sdk-ptest_qemux86-64_20201026224228 ptestresult.libinput.libinput-test-suite ptestresult.lttng-tools.tools/exclusion/test_exclusion_169_-_Excluded_event_"tp:tptest1"_was_found_in_trace! ptestresult.lttng-tools.tools/save-load/test_load_22_-_Destroy_session_tracker_legacy_all ptestresult.lttng-tools.tools/save-load/test_load_23_-_Destroy_session_tracker_legacy_none ptestresult.lttng-tools.tools/save-load/test_load_24_-_Destroy_session_tracker_legacy_selective ptestresult.lttng-tools.tools/tracker/test_event_tracker_208_-_Failed_to_parse_trace ptestresult.lttng-tools.tools/tracker/test_event_tracker_217_-_Validate_empty_trace ptestresult.lttng-tools.tools/tracker/test_event_tracker_250_-_Failed_to_parse_trace ptestresult.lttng-tools.tools/tracker/test_event_tracker_259_-_Validate_empty_trace ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_15_-_Validate_trace_for_event_cgroup_ns_=_4026532234 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_16_-_Read_a_total_of_0_events,_expected_1000 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_31_-_Validate_trace_for_event_ipc_ns_=_4026532233 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_32_-_Read_a_total_of_0_events,_expected_1000 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_47_-_Validate_trace_for_event_mnt_ns_=_4026532234 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_48_-_Read_a_total_of_0_events,_expected_1000 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_63_-_Validate_trace_for_event_net_ns_=_4026532237 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_64_-_Read_a_total_of_0_events,_expected_1000 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_79_-_Validate_trace_for_event_uts_ns_=_4026532234 ptestresult.lttng-tools.ust/namespaces/test_ns_contexts_change_80_-_Read_a_total_of_0_events,_expected_1000 Similarly: http://downloads.yoctoproject.org/releases/yocto/yocto-3.2.1/testresults/testresult-report.txt http://downloads.yoctoproject.org/releases/yocto/yocto-3.2.2/testresults/testresult-report.txt http://downloads.yoctoproject.org/releases/yocto/yocto-3.2.3/testresults/testresult-report.txt so I believe this issue has always been in 3.2
Later we disabled this test: http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=f443e3702113a5c3a837365f4f35aaa550875798
Not a regression, and there is a fix to disable it.
