* Fixed Issue 166: Memory leak with ATI Mobility Radeon 9700 Kenneth Russel2005-06-222-11/+33
| | | | | | | | | | | | | | | Worked around memory leak in ATI's OpenGL drivers by adding system property -Djogl.GLContext.nofree which users can specify on the command line. There is no good general-purpose workaround for this bug which works well on all hardware and in all kinds of applications. Issues may remain if this workaround is used and if the GLCanvas is removed and re-added to its parent container. Use at your own risk. Also cleaned up Windows ChoosePixelFormat code path; made sure PIXELFORMATDESCRIPTOR was completely filled out. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@306 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 151: starting up the Animator before the GLJPanel has been shown ↵Kenneth Russel2005-05-075-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | result in an error The root cause of this error was the fact that WindowsPbufferGLContext.destroyImpl() uses WGL extensions to clean up resources associated with the pbuffer. Because these extensions are in the public WGL interface, they are wrapped by the DebugGL. However, an OpenGL context is not current at the time these routines are called, and it is illegal to call glGetError() at those points. The DebugGL pipeline was implicitly calling glGetError() after each of those calls, leading to the failure. This bug unmasked a couple of others. The code in the DebugGL needed a recursion count to make sure that glGetError() didn't get called in an infinite loop. Also, as a side effect of the fix for Issue 160, calling getGL() on the GLJPanel outside of GLEventListener.init() was causing a NullPointerException to be thrown. The GLJPanel has been fixed to return null in this case, and the specification of GLDrawable.getGL() has been improved. In order to make the behavior between the GLCanvas and GLJPanel similar, the GL object is now reset in the GLDrawable each time the underlying OpenGL context is recreated. This allows end users to set up e.g. the DebugGL unconditionally in their GLEventListener.init() method. The JOGL demos have been changed to reflect this. The test case in the bug report will be updated with code similar to the originally submitted test case (i.e., the Animator is started early) but which now works. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@264 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 160: Resource leaks in GLJPanel Kenneth Russel2005-05-022-2/+57
| | | | | | | | | | | | | | Added addNotify and removeNotify to GLJPanel which clean up the associated OpenGL contexts and other resources. Extended JRefract demo to stress GLJPanel creation and destruction. New code appears to be correct. Can see resource leaks when the bunny is loaded over and over, but believe these are probably due to allocation of large NIO buffers that are not getting finalized promptly. Stressing the Gears demo with both the pbuffer and software rendering paths shows that the OpenGL resources are being reclaimed properly. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@263 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 148: Swing Component Shadow on GLJPanel Kenneth Russel2005-04-101-5/+1
| | | | | | | | | | | | | | | | | | The test case specifies alpha bits in the GLCapabilities, which caused the GLJPanel to create a TYPE_INT_ARGB BufferedImage to store the results of the readback of the frame buffer for rendering into the GLJPanel. This appears to not be the correct thing to do, because it causes this BufferedImage to be alpha-blended with whatever other rendering is performed into Java2D's backing store. Therefore when the button was redrawn, its image would show up in this backing store alpha-blended with the OpenGL rendering results since both were redrawn simultaneously. I believe the correct solution is to never create a BufferedImage with an alpha component for the framebuffer readback even if alpha bits are specified in the GLCapabilities. This is what has been implemented in the JOGL source base. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@258 232f8b59-042b-4e1e-8c03-345bb8c30851

Fixed these by making the const declarations correct for the conversion case of String[] -> char**.

On Windows, the most recent version of NVidia's drivers (66.93) when run on a GeForce 6800 causes a blue screen of death upon exit from the simplest JOGL demo (Gears). On Linux, JVM crashes have been reported upon exit of certain test cases on NVidia hardware. The same test case causes a report of an unexpected async reply from Xlib on ATI hardware (at the last time of testing -- I no longer have access to a Linux machine with ATI hardware because all of their currently available drivers crash the X server on my machine). On Mac OS X, low-level warnings from Cocoa are printed in multithreaded JOGL situations which can lead to JVM crashes. All of these problems' root cause is that the current OpenGL drivers on the market, or supporting software built on them, were not designed to be used in a multithreaded fashion. Most C programs which use OpenGL are either single-threaded or perform all of their OpenGL work from a single thread. JOGL was originally designed to support OpenGL rendering from arbitrary threads and appropriate synchronization was introduced into the library to handle this. However, we have had to scale back this support as stability issues have been encountered. The most recent round of reported bugs, including the PC crash upon exit of the JOGL demos, is serious enough that we must take drastic measures. Support was introduced in earlier JOGL releases to move all of the OpenGL work performed by JOGL and users' code via the GLEventListener on to the AWT event dispatch thread. It turns out that doing this works around all of the above reported bugs. In JOGL 1.1 b08 and 1.1 b09, code changes were made to make this single-threaded support more correct; this checkin includes another small set of such changes, including some to the GLPbuffer implementation, and changes the default of the flag controlling this support to true. -Djogl.1thread=true is now the default. -Djogl.1thread=auto restores the behavior of previous releases, which was to enable the single-threaded mode only with ATI cards. This auto-detection mechanism was not robust enough and adding cases for the crashes above was not feasible. -Djogl.1thread=false disables the single-threaded workaround. Older synonyms for this system property, JOGL_SINGLE_THREADED_WORKAROUND and ATI_WORKAROUND, remain in the source base for the time being. Changing the value of any of these system properties is not recommended. The expected performance impact of these changes is minimal. In earlier JOGL releases it appeared that the overhead of making a context current and releasing it each frame was very significant and a key differentiator in being able to match C performance. More recent tests seem to indicate that this is no longer the case, at least with current hardware. Regardless, we must achieve stability in order for the library to be useful and this seems to be the best means of achieving that goal. We believe that the compatibility impact of these changes for existing JOGL applications will also be minimal. For correctly-written JOGL applications, the only visible change in behavior should be that the values of thread-local variables accessed through the java.lang.ThreadLocal class may change since the actual thread on which the GLEventListener's callbacks will be executed may have changed. Multithreaded JOGL applications performing complex inter-thread synchronization may see subtle differences in behavior. We hope that such applications and the developers writing them will be able to handle this change in behavior without much trouble. We will continue to work with graphics card vendors to improve the stability of their OpenGL drivers. Until that happens, we believe this change will yield the best possible improvement in stability and portability for applications using JOGL. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@241 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | | | | | | | | This was a bug in the SGI GLU sample implementation and was reproduced by converting the attached test program to C and compiling in the code from the sample implementation. This bug was already fixed in the Mesa sources as bug 2510 and the patch was found at http://cvs.freedesktop.org/mesa/Mesa/src/glu/sgi/libutil/mipmap.c?rev=1.6&view=log by Googling for the terms "mipmap.c last row". The fix is to add a test-and-clamp for the highest row read from the texture. There is still a problem with visual artifacts when scaling non-power-of-two textures that this test case reproduces and that is continuing to be investigated. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@234 232f8b59-042b-4e1e-8c03-345bb8c30851
