rqt_top) Most of psutil missing in deb (groovy)

[dlaz]

psutil in the repo looks fine, but all that's showing up in the deb version is init.py(c). This makes rqt_top unable to display any info.

[ablasdel]

It sounds like the install rules are setup incorrectly. I will look into this.

[ablasdel]

Could you tell me what ubuntu distribution you are running? Also 32bit or 64bit? Apparently there are known platforms this doesn't work on currently: http://ros.org/wiki/rqt_top

[ablasdel]

@dlaz @130s I have noticed mentions all over of installing psutil as a work around. Where can I get more info on what/why we are doing this?

[dlaz]

12.04 64 bit. psutil is being packaged with rqt_top because the version available on Precise is missing some required features.

[ablasdel]

Not sure why it didn't click in my brain that you opened this ticket yourself dlaz! I was treating it like a community created ticket. Carry on and I will get out of your way!

[dlaz]

No worries. I'm not very familiar with how the packaging happens which is why I created a ticket rather than just fixing it.

[ablasdel]

Ahh ok to test what your package will put in the debian use "catkin_make install" Everything that shows up in the install dir will end up in your debian I believe. Try this and see if all the files show up where you want them.

Most likely what is going on is that you need to add a cmake install rule for the psutil workaround.

[dirk-thomas]

The embedded psutil is incomplete. It only contains the Python code but not the platform dependent libraries. Therefore it only works when the installed Debian package is new enough.

[dirk-thomas]

Please try the branch of pull request #109 on a precise machine and verify that it works with the Debian version of psutil (0.4.1)/

[ablasdel]

... and i should not have merged that before reading this comment...

[dirk-thomas]

Since you merged it already go ahead and check it on a Precise machine now :smile:

[ablasdel]

Doing so! But my my computer just crashed for an unrelated reason. I will test this ASAP

[ablasdel]

Sorry for my haste. I tested this on a 64 bit precise machine and nothing shows up in the rqt_top window when running a simple talker and listener node pair.

/talker_17279_1375480937887

[dirk-thomas]

With no error messages on the console?

[ablasdel]

Nope nothing I can see.

[ablasdel]

I am of the mind the close button is really not in the right place on github...

[dirk-thomas]

Your description does not really match any expectation: it should either work without error messages or produce a stacktrace and not load the widget at all.

Can you please make sure to uninstall the ros-groovy-rqt-top package, install python-psutil, checkout the branch of rqt_common_plugins and try it then?

[ablasdel]

That did the trick!

[dirk-thomas]

But this error has nothing to do with psutil. Can you please try it with running only a roscore but no additional nodes?

[ablasdel]

When I bring it up without any other nodes it comes up fine but is empty.

Are you coming today? I could show you my setup.

[dirk-thomas]

I verified it on another Precise machine here and it works fine.

I will come later to Willow and will take a look what's wrong with your setup.

[130s]

First of all, thanks all for fixing my commit!

1) I'm trying with 96624aef2cc90c2d5c470fd9b98155b56b096a16 merged into hydro, and saw the same error @ablasdel saw earlier on rqt_gui with:

terminal-1$ roscore  (that had been running for awhile)
terminal-2$ roslaunch pr2_moveit_tutorials planning_pipeline_tutorial.launch

This stopped occurring after I rebooted both, particularly roscore. ros-hydro-rqt-top deb was removed.

2) Now I see rqt_top's widget with no processes shown on it, with the same launch file.

python-psutil 0.4.1-1ubuntu1 is installed via rosdep install rqt_top. Precise 64b

[ablasdel]

Dirk fixed that on my machine. I believe he reinstalled the package but I am not certain. I'm sure he will post when he has a moment. It isn't an issue with commit but with the machine configuration.

[dirk-thomas]

You have to uninstall the current Debian package if you want to try the latest version from source since it provides an incomplete version of psutil.

[130s]

Current deb of rqt_top was removed as I updated my post...

[130s]

Now I verified the d730faf works on Precise w/o psutil. Looks like when I couldn't run it as expected, I was still having psutil installed under ROS directory (/opt/ros/groovy/lib/python2.7/dist-packages/psutil/) even after I apt-get purge rqt_toped for some reason. Now the folder is completely deleted, either by purge or by a combination of apt-get install -reinstall rqt_top and purge. Strange.
