From ba1ffe66697c3175b423cb7ab9b686d73959708d Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Thu, 31 Jul 2014 02:42:39 +0200 Subject: Bug 1039 - Specify behavior of GLEventListener Exceptions occurring while GLAutoDrawable processing [part-1] Implements Specification as described on 'Bug 1039 Comment 1' TODO: - Offthread exception handler ++++ GLDrawableHelper is used in all GLAutoDrawable implementations and for most operations. GLAutoDrawable/GLDrawableHelper invoke(..) method: - invoke(..) forwards a caught exception - if blocking, it forwards an exception happening within the passed GLRunnable(s). Here the exception is caught, printed and then thrown by invoke itself. - if non-blocking, an exception happening within the passed GLRunnable(s) will be thrown in the thread issuing it's execution, i.e. display() call. Here the exception is not caught and simply thrown by the GLRunnable. GLAutoDrawable.destroy() -> GLDrawableHelper.disposeGL(..) method: - disposeAllGLEventListener() being invoked by disposeGL(..), catches exception thrown by GLEventListener.dispose(..) and prints them to stderr. The first caught exception is re-thrown at the end as an GLException. - disposeGL() catches re-thrown GLException by disposeAllGLEventListener() for GLEventListener.dispose(..) and re-throws it when operation is complete. - disposeGL() catches an exception thrown at context destruction or release and re-throws it when operation is complete. An early exception at context.makeCurrent() is _not_ caught, since it is the first operation which simply shall unwind the stack. GLAutoDrawable.display() -> GLDrawableHelper.invokeGLImpl(..) method: - invokeGLImpl(..) for display() follows disposeGL() mechanism, i.e. it catches exception thrown at GLEventListener's init(..), reshape(..) and display(..) methods and re-throws it when operation is complete. It also catches an exception thrown at context release and re-throws it when operation is complete. An early exception at context.makeCurrent() is _not_ caught, since it is the first operation which simply shall unwind the stack. ++++ None of the above thrown exception shall be caught and suppressed on the caller side. If an operation must be completed while an exception is caught, it shall be cached and re-thrown after the operations. In case multiple exception at multiple places are caught within an operation, they all shall be cached and the first one shall be re-thrown. In case of multiple exception from the same place, i.e. a loop through all GLEventListener, the first shall be cached and re-thrown after operation is completed. It has to be determined, whether we like to dump the exceptions, especially the ones who get suppressed in case of multiple exceptions. --- .../classes/com/jogamp/opengl/swt/GLCanvas.java | 47 +++-- .../classes/javax/media/opengl/GLException.java | 14 +- .../classes/javax/media/opengl/awt/GLCanvas.java | 26 ++- .../classes/javax/media/opengl/awt/GLJPanel.java | 21 +- .../classes/jogamp/opengl/GLAutoDrawableBase.java | 33 ++- .../classes/jogamp/opengl/GLDrawableHelper.java | 96 +++++++-- .../classes/jogamp/opengl/GLFBODrawableImpl.java | 4 +- .../junit/jogl/acore/TestGLException01NEWT.java | 235 +++++++++++++++++++++ 8 files changed, 425 insertions(+), 51 deletions(-) create mode 100644 src/test/com/jogamp/opengl/test/junit/jogl/acore/TestGLException01NEWT.java (limited to 'src') diff --git a/src/jogl/classes/com/jogamp/opengl/swt/GLCanvas.java b/src/jogl/classes/com/jogamp/opengl/swt/GLCanvas.java index 03c6d6929..c409bb253 100644 --- a/src/jogl/classes/com/jogamp/opengl/swt/GLCanvas.java +++ b/src/jogl/classes/com/jogamp/opengl/swt/GLCanvas.java @@ -205,10 +205,9 @@ public class GLCanvas extends Canvas implements GLAutoDrawable, GLSharedContextS animatorPaused = false;
