Description

** clear and concise description of the bug is **

When using ros2 bag record --all --no-discovery, not all the topics that are available (the ones present with ros2 topic list) are subscribed to. I could not see a clear difference between the topics subscribed to and the ones left out. I found a workaround that could help you debug the issue, see it here: https://github.com/pixel-robotics/rosbag2/commit/0c885b3df35e9945b20e787a40b273aa295b6194

To Reproduce

** Steps to reproduce the behavior, e.g.

  1. Have a system with many topics open
  2. run ros2 bag record --all --no-discovery
  3. See that not all the topics available at startup are subscribed to

System (please complete the following information)

  • OS: Ubuntu Jammy
  • ROS 2 Distro: Humble
  • Version: release
  • DDS: Cyclone
