This looks good to me, assuming that Linux-rhel comes back green.

ros2cli test detected the segmentation fault as following.
which is really weird because what this revert PR changes is rclpy, and it breaks the ros2cli test. (we have met this before, ros2/ros2cli#932)

at least, this PR seems to fix original flaky reported https://ci.ros2.org/job/nightly_linux-rhel_release/2047/testReport/projectroot/test/test_graph__rmw_fastrtps_cpp/ in ros2/ros2cli#932 (comment)

maybe this segmentation fault is something else with RHEL.

retry CI:

• Linux-rhel
• Linux-rhel-debug

[fujitatomoya]

So reverting this does not turn the RHEL back on green.

i thought that this revert seems to address original flaky reported https://ci.ros2.org/job/nightly_linux-rhel_release/2047/testReport/projectroot/test/test_graph__rmw_fastrtps_cpp/ in ros2/ros2cli#932 (comment)

but recently, this is not happening in RHEL nightly debug,

• https://ci.ros2.org/view/nightly/job/nightly_linux-rhel_debug/2075/ looks exactly same with Revert "Adds types to Lifecycle Objects" #1373 (comment)
• https://ci.ros2.org/view/nightly/job/nightly_linux-rhel_debug/2074/testReport/junit/launch_testing_examples.launch_testing_examples/check_node_launch_test/launch_testing_examples_check_node_launch_test/ looks another flaky test
• https://ci.ros2.org/view/nightly/job/nightly_linux-rhel_debug/2073/ looks exactly same with Revert "Adds types to Lifecycle Objects" #1373 (comment)
• https://ci.ros2.org/view/nightly/job/nightly_linux-rhel_debug/2072/testReport/junit/launch_testing_examples.launch_testing_examples/hello_world_launch_test/launch_testing_examples_hello_world_launch_test/ looks another flaky test
• https://ci.ros2.org/view/nightly/job/nightly_linux-rhel_debug/2071/ looks exactly same with Revert "Adds types to Lifecycle Objects" #1373 (comment)

according to last 3 days release/debug RHEL nightly result, i do not think reverting this is the right way...

[fujitatomoya]

Some experimental RHEL jobs are running, hopefully this can tell us which commit generates the error. (if that comes on green, that is the suspect.)

[fujitatomoya]

So after all, it says https://github.com/ros2/rclpy/pull/1363/files is the one that generated the regression. can anybody tell me why ❓❓❓

[fujitatomoya]

i will go ahead to close this. because this is NOT the cause of the flake8 segmentation fault, and we can keep tracking with ament/ament_lint#505.
