Unable to run flashplayer under Jenkins

[Wim Deblauwe]

Hi,

I am trying to get the latest flashplayer running under Ubuntu using WINE with Jenkins using vncserver. I have it running fine when logging in manually as the 'jenkins' user. I can see the flashplayer in the remote desktop. However, it does not work from inside the Jenkins application.

This is what the log shows:

The most important line is probably:

[DEBUG] [SYSERR]: libGL error: failed to load driver: swrast 

I can reproduce this error with glxinfo (Ubuntu command line tool) running as the jenkins user:

The strange thing is that I can start flashplayer this way (manually from the command line as the jenkins user) without an issue. But starting this same flashplayer script (which in turn starts wine to start the flashplayer .exe) in a jenkins build fails with the same message as glxinfo:

jenkins@wdb-vb-java7:~/jobs/Flux/workspace/client-domain$ LIBGL_DEBUG=verbose glxinfo
name of display: :1

libGL error: failed to load driver: swrast

You can see more info at my question: http://askubuntu.com/questions/401459/failure-to-load-swrast-driver

Any idea what might the difference between Jenkins the webapp running and logging in manually as the jenkins user ?

A real user has $DISPLAY set, Jenkins has not. You could try using Xvfb to give your Jenkins job a (virtual) display (there should even be a Jenkins plugin).

I am using vncserver and the vncserver plugin in jenkins to provide $DISPLAY. I check with a pre-compilation step if $DISPLAY is set and it is. I can connect with vinagre to the remote desktop while the jenkins job is running.

Can you tell exactly which VNC server package you have installed (and which Ubuntu version it is)? My Ubunutu 13.10 offers 3 different VNC server packages:

tightvncserver - virtual network computing server software
vnc4server - Virtual network computing server software
x11vnc - VNC server to allow remote access to an existing X session

I will then try to reproduce this @home.

Bye...

I could reproduce the problem. However, I didn't find a solution. Looks like both Xvnc and Xvfb don't have proper OpenGL support. Maybe you could setup a Windows slave (VM) for running flashplayer.

HTH...

Hi, 

Thanks for testing this. But how come it can work if I start flashplayer manually from the command line into Xvnc ?

Is it possible to only run 1 maven child project in a multi-module project on a different slave ?

regards,

Wim

I haven't tried running flashplayer under Wine connected to a vncserver so I can't say if it's reasonable to expect it to work. However, any difference in behavior you're seeing is most likely the result of differences in the environment, whether DISPLAY or some other variable. I had a number of difficult to understand problems with my Jenkins builds until I made a concerted effort to set up the same environment in an interactive login and Jenkins job run.

Since OpenGL is involved, I'd look at variables which affect shared library loading. It's even possible that when you run flashplayer in an interactive shell, it's using the OpenGL library of real hardware while displaying in a vncserver.

Hi,

"Since OpenGL is involved, I'd look at variables which affect shared library loading."

Do you have information on what variables that are? I suppose PATH is, but are there others?

"It's even possible that when you run flashplayer in an interactive shell, it's using the OpenGL library of real hardware while displaying in a vncserver."

Sounds crazy, but it could explain the behaviour I see indeed.

Wim

The man page for the dynamic loader would be a good place to start. You
also might want to look at the docs for the particular OpenGL
driver/library currently in use. Or, just look at variables which are
different between the interactive shell and Jenkins job environment.
