* 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

| | | | | | | | | | | | | old rendering model. Added SingleThreadedWorkaround.disableWorkaround(); for now, don't want to add this to the core JOGL API because at some point the SingleThreadedWorkaround should hopefully really become an implementation detail that no application should have to worry about. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@259 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 Issue 154: Patches for build problems Kenneth Russel2005-04-042-6/+7
| | | | | | | | | | | | | | Submitted patches had a couple of problems. First, the removal of the (incorrect) cast to const char* in the CMethodBindingEmitter caused build warnings on other platforms. Fixed these by making the const declarations correct for the conversion case of String[] -> char**. Second, addition of comparison of hashCodes in CompoundType.equals() seemed like too much of a hack. Fixed this by correcting potential problems in equals() and hashCode() methods; not sure whether this will solve the submitter's original problem, though. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@254 232f8b59-042b-4e1e-8c03-345bb8c30851

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

* Partial fix for Issue 140: glu.gluBuild2DMipmaps crash Kenneth Russel2005-02-231-0/+24
| | | | | | | | | | | | | | | | | 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

This checkin attempts to make the needed changes to the pbuffer implementation on other platforms, but the GLJPanel continues to use software rendering until all platforms can be tested. Additionally, references to static final DEBUG flags have been made settable via system properties. "jogl.verbose" enables certain printing statements. "jogl.debug" enables all debugging printing.

* Fixed Issue 118: EXCEPTION_ACCESS_VIOLATION on show of 2nd canvas ↵Kenneth Russel2005-01-313-2/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (ATI-specific) The root cause of this bug was not the new DummyGL code, but severe bugs in ATI's OpenGL drivers where it appears that if an OpenGL context is ever made current on more than one thread during the lifetime of an application, problems begin to occur such as the SetPixelFormat call failing on the just the next newly-created HDC, or all subsequent SetPixelFormat calls failing on all subsequently-created HDCs. This was occurring because the single-threaded ATI workaround's automatic detection mechanism was not being enabled until the first time a context was made current, but by then it was typically too late; the context was made current on the end user's thread during e.g. Frame.show(), and if it was ever made current on another thread (like the AWT event queue thread, which is where all OpenGL operations are performed when the single-threaded workaround is enabled) then the problems would begin. The failure has only been seen on Windows so far; ATI's drivers on X11 seem to be better behaved. The workaround is to check for the presence of ATI's drivers very early during JOGL's initialization, by looking in the system directory for atioglxx.dll, and enabling the single-threaded workaround if it was found. This workaround causes the attached test case to work properly. Also added some more debugging code to make diagnosing problems like these easier in the future. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@196 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | | | | | | | | | | | | | | | | | The root cause was that JOGL's single-threaded workaround had a bug where if automatic swap buffer support was disabled, the user's calls to swapBuffers() were not being retargeted to run on the AWT event queue thread, as calls to display() were. The effect of this was that the OpenGL rendering was not necessarily guaranteed to complete before swapBuffers() was called, unless a glFlush() / glFinish() pair was inserted. Interestingly, testing showed that inserting the glFlush() / glFinish() just before the call to swapBuffers(), which was executing on the user's thread rather than the AWT event dispatch thread, did not cause the rendering output to complete properly. This implies either a bug in the implementation of glFlush() / glFinish() on the testing platform or a misunderstanding on my part of how these APIs behave. Putting the flush/finish after all of the OpenGL work done by the user in their display() routine worked correctly. Regardless, the intent of the single-threaded workaround was to cause all OpenGL-related work to be done on the event dispatch thread, which it now does. This fixes the reported problem. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@195 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | | | | | | | | | | | window is visible The issue (or a related one) is still present in the current JOGL build, although the symptom was different: a deadlock upon startup of the application. When the OpenGL context is created in the WindowsOnscreenGLContext implementation, it causes Component.getGraphicsConfiguration() to be called, which causes the AWT tree lock to be grabbed. Under some circumstances, another thread can already hold the AWT tree lock and call GLContext.invokeGL(), which leads to a classic deadlock. Resolved this by eagerly grabbing the tree lock under some circumstances (not all the time) before entering the synchronized invokeGL in (only) the Windows onscreen context implementation. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@193 232f8b59-042b-4e1e-8c03-345bb8c30851
* Partial fix for Issue 88: Add Linux amd64 support to JOGLKenneth Russel2005-01-276-9/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stub_includes headers and GlueGen config files have been changed to make X identifiers and similar values appear to Java to be 64-bit values on all platforms, rather than changing between 32-bit and 64-bit values depending on the architecture. This allows the shared Java code in the JOGL X11 implementation to work on both 32- and 64-bit architectures, which is an important step toward having complete 64-bit support in JOGL. Compared to the suggested patch, there is no longer a need to duplicate the sources in net.java.games.jogl.impl.x11 because the Java sources are now 64-bit clean. The change to use dlsym on Linux/AMD64 instead of glXGetProcAddressARB has been conditionalized under a run-time flag. Most of the build.xml and all of the GlueGen changes were incorporated unchanged. Thanks to the original authors of the patch for this work. At this point "ant linux.amd64" should build a working JOGL. However, it can not yet be incorporated into the distribution's platform- independent jogl.jar; in order to do this, the generation of the StructAccessors for the JAWT and some other X11 data structures by GlueGen will need to be conditionalized depending on the platform so that the 32-bit versions go in one directory, the 64-bit versions in another, and a run-time check is done to determine which version to instantiate. There are also a few remaining cleanups to generated glue code such as net.java.games.jogl.impl.x11.GLX.XGetVisualInfo(), which needs to be made platform-independent by calling the XVisualInfo.size() accessor rather than hardwiring in the size of the data structure (although the real solution will probably need to be more complicated since there will probably be two XVisualInfo implementations in the jar file). git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@190 232f8b59-042b-4e1e-8c03-345bb8c30851
