High CPU usage with int32_publisher #297

Open yashi opened 1 year ago

yashi commented 1 year ago

Describe the bug Having only timers on an executor makes rmw_wait() to spin without blocking. This causes high cpu usage and it's a problem on a RTOS with threading support.

To Reproduce Just build int32_publisher from micro-ROS-demos.

Expected behaviour rclc_executor_spin() should always be a blocking call without any service, client, subscription, or timer.
