Crash when loading layout file

[jmailloux]

Thanks for contributing to PlotJuggler. You are great!

Problem description

I save a layout file that has a Custom Series called Power (save custom transformations option is selected. It multiplies current and voltage. I then close plotjuggler and reopen it, and load the layout file. It crashes in lua_rawgeti.

I've attached the layout file.

This is using main. The crash does not happen on 3.2.

Steps to reproduce (important)

See description

• Describe your platform / Operative System.
  I'm using MacOS Big Sur. I know MacOS isn't supported. Submitting this in case it happens on other platforms as well.

• Check if the problem can be reproduced using the dummy data created by the command line argument "-t" or one of the files in the folder "datasamples".

• If it can't be reproduced with the dummy data, please share the CSV file or the rosbag that can be used to reproduce the problem.
  layouts.zip

I'm seeing similar issues on Ubuntu with ros2 run plotjuggler plotjuggler -d <bag_file> -l <layout_file>

Hi @jmailloux

The layout you shared don't contain the information about the file, therefore I assume you first load the file and then load the layout.

I can not reproduce the error. Can you send the entire backtrace?

[jmailloux]

Hi @facontidavide.

All I have to do is load the layout file. There is no log file if that is what you are asking. If I load a log file first, then load the layout file. Same thing happens. Here is the stack trace:

I tried this on an Ubuntu VM. Layout file is slightly different than what I posted above. I loaded the layout file. Plotjuggler hung this time. I tried loading a log file, then loading the layout file. Plotjuggler crashed

crash layout and log.zip
.

[facontidavide]

ok. First of all, the layout don't crash with latest version of PlotJuggler.

On the other hand, I can see a limitation of the Layout + Custom Series, that fails when one custom series depend on another, as in your case.

Let me see if I can fix the later issue.

[facontidavide]

Fix pushed

Let me know if you have still problems

[jmailloux]

@facontidavide , thanks for the patch. The first thing I did after opening PlotJuggler after I rebuilt it is try to open efficiency.xml (without loading a data file). It crashed. See below stack trace. Should I open another issue?

[facontidavide]

I am sorry that you still have problems, but unfortunately I can not reproduce this on my side, therefore I can hardly find a solution.

The only thing that I noticed here in your backtrace is that there is not reference to PlotJuggler at all.
I wonder if this is aproblem of binary compatibility (parts of the code compiled with a different QT versions), but I honestly have no idea.

Sorry

[jmailloux]

OK. Thanks. I'd be happy to run experiments if you had anything you wanted to try. Only other thing to note is I have an ARM based machine. I wonder if doing what I am doing is causing memory corruption. What is getting corrupted when you try to reproduce is not causing problems. What is getting corrupted when I try to reproduce causes a crash. I have a colleague who also see crashes in plotjuggler. He is running Windows on x86. I can see if he can reproduce the crash using the same reproduction steps I am using if that would help.

[jmailloux]

On MacOS, plotjuggler 3.2.0, if I load the xml, then the log, it crashes with this stack trace.
libc++abi: terminating with uncaught exception of type std::out_of_range: unordered_map::at: key not found

If I load the log, then the xml, it doesn't crash. But if I then load another log, it crashes with the same stack trace.

[facontidavide]

Ok , this last piece of information give me some hint.... I wonder where this std::out_of_range: unordered_map::at: is coming from... I will investigate.

[facontidavide]

just to be sure: DO NOT USE 3.2.0. Use master only, compiled in debug mode by yourself.

Otherwise, it could be an issue I solved already and we are wasting time.

[jmailloux]

Got it. Definitely don't want to waste your time. The Linux crashes have all been from master that I compiled myself. The MacOS one was also from master, but from a while ago, that I compiled myself. I can update to latest on MacOS and try if that would help. Just to clarify - when you say compiled in debug mode - I compile by following the instructions on the github page. I don't do anything different.

[facontidavide]

Please compile like this

mkdir build; cd build
cmake -DCMAKE_BUILD_TYPE=Debug  ..
make -j

This should provide much more informative backtrace.

Aldo consider that loading the layout BEFORE the data is NOT expected to work properly.
It MUST NOT crash, but it is not expected to magically work either.

[jmailloux]

OK. On the first try, the debug version on Ubuntu did not crash. :)

I will keep using it and report if it crashes.

[jmailloux]

OK. Got a crash after loading a different log:

[facontidavide]

I have found a pretty serious bug and (fingers crossed) this MIGHT be related to yours.

Can you try the latest main with 2ca9a91 ?

[jmailloux]

Hello @facontidavide, your changes seem to fix the crash. However, if I do the following:
Load a log file (log_12 for example), then load the layout file, everything works fine. The graphs show up and so do the custom series. If I then load another log file (log_14), and click "Yes", I do want to remove previously loaded data, none of the graphs or custom series show up. I've attached the logs I am using and a screenshot of what I see after I try to load the second log.

[logs.zip](https://github.com/facontidavide/PlotJuggler/files/7449691/logs.zip

)

[jmailloux]

Loading the log file, then the layout still crashes on MacOS.

I still can't reproduce the issue in Lua, but I added something that you will like:

pj_reload-2021-11-01_16.06.41.zip

Loading a different file with almost the same data should work now and Custom curves are recalculated, as they should.

[facontidavide]

I am closing this because now it is a duplicate of other issues

[lgkimjy]

I have similar issue with this, while I tried to use the UDP streaming, plotjuggler crash after I click the start button.

I tried with this solution, but it didn't solve my crash problem. @facontidavide, is there any other suspicious problem that I might be able to fix? I am currently using a Mac M1 Pro.
