Based on the documentation I have seen at the links below

It seems ros2 nodes are supposed to support dynamic remapping of their topics at runtime. However, I do not see any documentation on this. I feel this feature is useful during development and debugging, so I would like to see it implemented.

Is this feature implemented in Dashing? If not, is it still on the roadmap?

If you haven't tried already, I recommend reading through the DDS Tuning guide and trying out some of the options. https

As of ROS2 Eloquent we can use xml or yaml for writing launch files. Previous versions of ROS2 used python with the roslaunch API. So my question is which of these methods is currently recommended or considered best practice?

I will be converting an existing ROS1 package to ROS2 Foxy and I need to decide how to update the launch structure. I'm leaning toward XML since that will make the conversion more straightforward, but if python files are now considered best practice I will follow the community standards.

Update from Answer: After reviewing the documentation based on the concerns with XML functionality pointed out by @stevemacenski, I have decided to stick with python until XML adds support for components as they are the recommended way to design nodes https://discourse.ros.org/t/ros-2-das....

Looking for recommendations for ROS nodes or C++ libraries that can take multiple independent camera image streams and combine them into a single 360 deg image stream. I’m looking for something that handles stitching the images together rather than just overlaying them based on the URDF file. Any recommendations?

I have a large ROS network comprised of both ROS1 and ROS2 nodes. The nodes are bridged by the ros1_bridge dynamic_bridge.

Two of the ROS2 nodes publish VLP-32C lidar data as sensor_msgs/PointCloud2 onto two different lidar topics at ~10Hz. When the system starts up the ros1_bridge will correctly identify these topics and start forwarding these messages. However, after a few seconds at least one of the lidar streams will stop bridging and that lidar's data will no longer be available on the ROS1 network. It appears the ros1_bridge is still connected on both ends, but no lidar data is coming out. The ROS2 lidar data is still publishing and other messages are still being bridged.

I'm a bit at a loss for what might cause this. Does anyone have any suggestions on how to investigate.

I'm using Ubuntu 20.04 with ROS2 Foxy, ROS1 Noetic, and Cyclone DDS.
