Re: [cross-project-issues-dev] UI tests on HIPP - segfaults and browser

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Hi Carsten,

I suppose that libwebkitgtk.so is not installed or otherwise not working on your HIPP. 

Eclipse would usually prefer webkitgtk over xulrunner automatically if it’s available.
By enforcing webkitgtk, you enforced a non-working configuration. 

Perhaps at least temporarily you should consider running on GTK2, by setting the SWT_GTK3 environment variable to 0:
https://www.eclipse.org/swt/faq.php#gtkstartup

Since you probably don’t have shell access to you HIPP, you may have to file a Bugzilla asking Webmaster’s help to add a working version of libwebkitgtk.so to your HIPP.

Thanks,
Martin

    Hi everybody,
    
    Do any of you have UI tests running on HIPP? I'm running SWTBot tests on the MPC HIPP using Xvnc, and I'm currently having a couple of problems:
    
    1. MPC is using the embedded SWT Browser widget, and since the default XULRunner support doesn't work on GTK3, I moved my tests to WebKit (using -Dorg.eclipse.swt.browser.UseWebKitGTK=true -Dorg.eclipse.swt.browser.DefaultType=WebKit). Now I just get a very nondescript "Internal browser is not available: No more handles" SWT error the first time the browser is initialized, and all my browser-related tests (still) fail.
    
    2. I recently switched my target platform to Oxygen, and now my UI tests always segfault somewhere down the line:

    > # Problematic frame:
    > # C  [libgdk-3.so.0+0x38510]  gdk_test_simulate_button+0x0
    
    It looks like this happens the first time SWTBot "clicks" on a Link widget. But I don't have the faintest idea what to do about it.
    
    What makes this even more complicated is that I can't reproduce any of this in my own Linux VM. So any ideas how to get this solved would be greatly appreciated.
    
    /cheers
    Carsten
