Invalid read & leaks in node and publisher destruction #404

Closed ihasdapie closed 1 year ago

ihasdapie commented 1 year ago

When valgrinding some rcl tests I noticed that there are invalid reads and leaks happening in the destruction of nodes and publishers happening in CycloneDDS after the rmw_publisher_destroy, etc. calls.

From original issue: https://github.com/eclipse-cyclonedds/cyclonedds/issues/1376:

Those are actually issues in rmw_cyclonedds: it is not calling dds_delete_listener and dds_delete_qos as it is supposed to do. Hopefully I can move this issue, otherwise I'll have to close it here.

I just reran this test on the latest rolling, and I can't see these errors anymore. I'm not totally sure what fixed it, but I'm going to close this out for now.
