2023-02-17 08:44:12 -0500 | marked best answer | Why do I get deadlock when setting a future in a subscription callback? (Only with MultiThreadedExecutor) (rclpy) I have a node that publishes message, and another node (constructed with an unset future) that sets the result of the future to the incoming message in its subscription callback. I then add both of these nodes to an executor (in the same process) and spin until the future is complete. If I am using a My Publisher Node looks like this: My Subscription Node looks like this: And I start the Nodes like this: I have also tried: But I have the same issue. The The full code can be found here, with instructions on how to run it here. Why does this happen? Or is this a bug in ros? I will submit an issue if this is a problem with ros, and not just how I am using it. If that is the case, where should I submit the bug report? Thanks. Edit: I have submitted a bug report here |
