Re: N950 SEGFAULT - help?

2011-11-11 Thread Felipe Crochik 
I have created a new project from scratch and modified the bare minimum I
could to make sure I didn't introduce a bug.

This project uses the original source code for the declarativewebview from
Qt4.7 (I did not see any difference when compared to 4.8). The only change
is that it offers a different user agent so google will return the Android
version.

I can reproduce the crash by:
1. login to a gmail account
2. go to inbox
3. switch to the task manager
4. switch back to the application
5. click back to menu and select another folder (it seems that is related
to triggering a reload of the page but the exception seems to be related to
QPaint)

Also, it crashes almost every time I switch to the task manager while
loading something.

The source and a deb file can be found at
http://www.crochik.com/gapp/webviewcrash.zip

Any help greatly appreciated since the application is pretty useless you
can't leave it running.

Thanks,
Felipe

   That’s not how it’s done.

 1. In your .pro file, add:
 QT += opengl

 2. at the top of your cpp, add:
 #include QGLWidget

 3. when you initialize your QDeclarativeView:
 QGLWidget glWidget;
 QDeclarativeView view;
 view.setViewport(glWidget);

 Cheers,
 Timur

 Nicolai,

 I tried the application using (I assume that is what you meant):
 QApplication::setGraphicsSystem(opengl);

 and haven't been able to crash the application but it gets really slow
 and unresponsive. Also I get these error messages on my log:

 Valid eglHandle received but not running with meego compatible
 graphicssystem.

 Any ideas?

 Thanks,

 Have you tried to use a QGLWidget for the qmlviewer ?
 This works for the QML Camera element which has the
 same behavior, segfaults when application moved to background.

Note that in general GL context should be dropped in applications
when they aren't visible. Main exception for this rule are plain GL
games because they cannot do this easily and user isn't typically
running many such games at the same time, like could be the case
with normal apps.

This is because GL contexts are severely limited resource and after
system runs out of them, any new processes just abort/crash on startup
because GL init fails.

Dropping GL context on background should happen automatically for
most MeegoTouch and QML applications.  If you're directly using GL
operations in such applications without taking this account, and
e.g. trying to do GL drawing in the background, funny things may
happen.

Re: N950 SEGFAULT - help?

2011-11-05 Thread Nicolai Hess 
2011/11/5 Felipe Crochik fel...@crochik.com

 Unfortunately It didn't do the trick I can't tell any difference
 ...still crashes with the QPainter::save()

 Please let me know if any of you have any more ideas... I will play a
 little more tomorrow.

 Felipe


 2011/11/5 Kristóf Timur ti...@sch.bme.hu

   That’s not how it’s done.

 1. In your .pro file, add:
 QT += opengl

 2. at the top of your cpp, add:
 #include QGLWidget

 3. when you initialize your QDeclarativeView:
 QGLWidget glWidget;
 QDeclarativeView view;
 view.setViewport(glWidget);

 Cheers,
 Timur

 Nicolai,

 I tried the application using (I assume that is what you meant):
 QApplication::setGraphicsSystem(opengl);

 and haven't been able to crash the application but it gets really slow
 and unresponsive. Also I get these error messages on my log:

 Valid eglHandle received but not running with meego compatible
 graphicssystem.

 Any ideas?

 Thanks,
 Felipe



 2011/10/7 Nicolai Hess nicolaih...@web.de

 Have you tried to use a QGLWidget for the qmlviewer ?
 This works for the QML Camera element which has the
 same behavior, segfaults when application moved to background.


 2011/10/7 Felipe Crochik fel...@crochik.com

 That is the next problem. They are not available - maybe I need to
 add some extra repository? sorry if I missed some obvious development
 required step It is hard to start over!

The libpvr libraries are binary blobs for the PowerVR GPU and have nothing 
to do with QT.
No I dont know where you would get appropriate blobs that will not cause 
the errors you are seeing.
