Cannot interrupt service server using fastrtps or connext about rclpy HOT 6 CLOSED

Confirmed that demo_nodes_cpp service server can be interrupted no problem, so this is just an rclpy issue

from rclpy.

I just tried it with sourcing the referenced build on the same Windows machine (windshield) and it was interrupt able without a problem (just tried with the default FastRTPS):

C:\J\workspace>packaging_windows\ws\install\Lib\demo_nodes_py\add_two_ints_server.exe

KeyboardInterrupt

Same result with the last nightly debug buiild on portable.

from rclpy.

The windows version between my VM and the build machine are different (10.0.10240 vs 10.0.17324.112). I'm struggling to find any other difference. If a third machine doesn't show the same issue I would vote to close this.

On icecube a build from a couple of days works too.

from rclpy.

Retested using https://ci.ros2.org/view/packaging/job/packaging_windows/1060/ on my VM and on windows_portable. The behavior has changed :(

Using my VM there is no response to CTRL + c using fastrtps and connext, and now there is also no response when using opensplice. I'm still able to interrupt the demo_nodes_cpp server no problem.

Using windows_portable the first time I tried to CTRL + c demo_nodes_py/add_two_ints_server.exe it hung. I tried to interrupt it multiple times over a few minutes and it never responded. I opened another cmd window and every time I am able to interrupt it using any rmw implementation.

Maybe there is a race condition that is made worse on earlier windows 10 versions? Portable is Windows 10 Enterprise v1803 while my VM is enterprise v10240 (older despite being a bigger number)

Closing this assuming it is not present on more recent versions of windows.
