rqt_plot Does not start up if topics are no longer available #110
Comments

@DorianScholz This looks like a rare occurrence but it might be better just to mark the topic as "not receiving" or something. otherwise we lock things up. |
|
This issue is actually common to us. |

I had never seen this before when chad showed it to me. Do you run into it often issac? |
|
Here is the offending code: https://github.com/ros-visualization/rqt_common_plugins/blob/hydro-devel/rqt_plot/src/rqt_plot/rosplot.py#L87 sleep in a loop until it gets the topic type info. Switching this to a lazy load of topic type will probably solve the problem. Though we would probably have to introduce the concept of plot elements that are "off" or at least not receiving data at the moment. Interesting note: Adding the concept mentioned would make implementing #106 much easier |
|
@130s Are you working on this one at the moment? I was going to take a crack at it and just want to make sure we don't duplicate work. |
|
Please go ahead; I'm stuck with other issues. |
|
My pull request will address the major issue at hand so people can use it without rqt getting into a stuck state. |

fixes #110: no waiting on unpublished topics
|
Quick comment to help out chadrockey. I had this issue as well, and was able to fix it with the '-e' option. When you want to use rqt_plot, launch it with 'rosrun rqt_plot rqt_plot -e'. This option will start the plotter without attempting to restore previous topics. Hope that helps. |

My use case is that I've launched plot, looked at some topics, closed rqt_gui and moved onto another problem.
When I come back to use rqt_gui again, it looks for the last topics I've used. Unfortunately, it also waits on the order of minutes to give up and actually allow me to use the tool. To make matters worse, it waits for EVERY topic that was previously plotted. In order. 😦
Example console output:
WARNING: topic [/imu_integrated/angular_velocity/z] does not appear to be published yet. Waiting...
WARNING: topic [/odom/twist/twist/angular/z] does not appear to be published yet. Waiting...
