From 9e87acd921bcb357f1ec88d166bde672b54b02c8 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Fri, 3 Aug 2012 01:38:37 +0300 Subject: Fix X11 Display Connection leak w/ new GLAutoDrawableBase code when used w/ offscreen drawables, reported by Mark Raynsford New common GLAutoDrawableBase missed to close the AbstractGraphicsDevice in case it has been created and dedicated for the passed GLDrawable. This detailed knowledge is only known to the creator, hence it is passed in the constructor and is being passed through all specializations. Further more the new X11/GLX impl. of GLDrawableFactory's 'createMutableSurfaceImpl' always creates it's own private X11 display connection to avoid locking / threading issues. Since the old implementation reused the shared display connection which is prone to threading issues, this bug was not visible before. Also fixed the unit test TestNEWTCloseX11DisplayBug565, now correctly validating that no display connection is left over after a new cycle of create/destroy of onscreen and offscreen drawables. --- .../classes/com/jogamp/opengl/OffscreenAutoDrawable.java | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'src/jogl/classes/com/jogamp/opengl/OffscreenAutoDrawable.java') diff --git a/src/jogl/classes/com/jogamp/opengl/OffscreenAutoDrawable.java b/src/jogl/classes/com/jogamp/opengl/OffscreenAutoDrawable.java index 1ea8595c6..8450ffdb0 100644 --- a/src/jogl/classes/com/jogamp/opengl/OffscreenAutoDrawable.java +++ b/src/jogl/classes/com/jogamp/opengl/OffscreenAutoDrawable.java @@ -28,6 +28,7 @@ package com.jogamp.opengl; +import javax.media.nativewindow.AbstractGraphicsDevice; import javax.media.opengl.GLAutoDrawableDelegate; import javax.media.opengl.GLContext; import javax.media.opengl.GLDrawable; @@ -45,8 +46,16 @@ import jogamp.opengl.GLFBODrawableImpl; */ public class OffscreenAutoDrawable extends GLAutoDrawableDelegate { - public OffscreenAutoDrawable(GLDrawable drawable, GLContext context, Object upstreamWidget) { - super(drawable, context, upstreamWidget); + /** + * @param drawable a valid {@link GLDrawable}, may not be realized yet. + * @param context a valid {@link GLContext}, may not be made current (created) yet. + * @param ownDevice pass true if {@link AbstractGraphicsDevice#close()} shall be issued, + * otherwise pass false.
