Preparing for Noetic Sync 2024-05-09

Hello Noetic maintainers!

Starting now, I will be holding new Noetic ros/rosdistro release PRs with a plan to sync ROS Noetic packages to the main apt repo on 2024-05-09. Please comment here if there are any issues I should know about before performing the sync.

There are currently 71 packages waiting to sync and 3 regressions.

I found a (IMO) medium critical bug in the to-be-released RViz 1.14.22: After PR #1808: Segfault when loading RViz config with RobotModel display using non-default parameter name · Issue #1825 · ros-visualization/rviz · GitHub .

It will lead to segfaults for users with stored RViz configs that use a RobotModel display configured to use a non-default parameter name while also specifying another model on /robot_description ROS parameter.

Not sure if this is something the release should be held off for. In some of our use-cases, we have this configuration (i.e. multiple robot models on multiple parameters with one of them being the default /robot_description).

We would be affected by this as well. Wasn’t aware of the issue.

I will only find time on Sunday, May 12th, to look into this.

@Timple could you please try to replicate the issue with either rviz from noetic-devel or the prerelease binary?

I fixed the issue. Was actually easy.

You’re just awesome, thanks!

Thank you for reporting the issue @peci1 and @Timple , and thank you for fixing it so quickly @rhaschke!

I’m going to give the sync freeze one more day. I want to try out RViz myself, and I want to make sure there’s no issues with some other releases that were merged during the freeze by mistake.

We ran into an issue with the map display with that new RViz upgrade. I opened an issue on GitHub with details here: Map Display jumps due to Qt::QueuedConnection · Issue #1826 · ros-visualization/rviz · GitHub

The sync is out :tada: . Now is a great time to make releases for the next sync :shrimp: :fried_shrimp:

Not sure if this is the right place to ask, but I have a question about ROS mirrors related to the latest rviz release: are the packages’ old versions deleted as soon as new versions come out? The newest rviz version broke my build, so I tried to rollback to an older version; however I could not find version 1.14.20 mirrors.

$ sudo apt-cache showpkg ros-noetic-rviz
Package: ros-noetic-rviz
1.14.23-1focal.20240509.203011 (/var/lib/apt/lists/packages.ros.org_ros_ubuntu_dists_focal_main_binary-amd64_Packages) (/var/lib/dpkg/status)
 Description Language: 

Yes, the PPAs only hold the latest version. To access older versions, use the snapshot repos: SnapshotRepository - ROS Wiki . However, if you only reinstall rviz from the snapshot repo, it might happen that you’ll get segfaults if you use custom plugins for displays/tools etc. You should ideally reinstall everything that build-depends on rviz (you can begin here: ROS Package: rviz, but it lists not only build-depends). And even then, there is chance you’ll get segfaults if the ABI of some other packages changed. If you’re building in a Docker/singularity environment, you’ll rather use the snapshot repo as PPA and you’ll be free of any of the mentioned problems.
