From 1d333a771ce0bc7c8594e21d031703f698f06a46 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Thu, 10 Jun 2010 09:35:06 +0200 Subject: Fix: Locking/Threading; Common IntIntHashMap and Buffers; Fix: glMap*Buffer*; GLX/WGL/CgGL: All runtime dynamic; Misc .. TODO: Compile and test on MacOSX .. Fix: ===== Multithreading/Locking: See jogl/doc/Implementation/MultiThreading.txt - Locking layer is not platform agnostic, ie GLContextImpl, GLDrawableImpl, .. and NEWT: Window/Display - No more use of JAWT global lock necessary, removed. - No need for X11 Display lock, on the contrary, this made the NV driver hang. - Use common window/surface lock - All NativeWindow surfaceLock's are recursive now glMapBuffer: If size is 0, don't do cont with the native call. glMapBufferRange: Fix capacity. glNamedBufferDataEXT: Track the size. glMapNamedBufferEXT: Manual impl. - use the tracked size glXGetVisualFromFBConfig, glXChooseFBConfig, glXChooseVisual: Instead of ignoring and implement a renamed version (*Copied), we just use ManualImplementation for the proper copy-result code. DesktopGLDynamicLookupHelper: Initialize _hasGLBinding* attributes in the determing loadGLJNILibrary() method, which is called by super(). Otherwise static init will overwrite them after the super() call. X11GLXDrawableFactory: Don't release anything at shutdown (removed sharedContext.destroy()), since this caused a freeze/SEGV sometimes. Fixed NEWT's reparentWindow() functionality incl NewtCanvasAWT usage. - Native: if not visible, don't focus, etc - NewtCanvasAWT: Use the container size to start with - Run the command on the EDT Using GlueGen's new DynamicLibraryBundle utility: - X11, Windows and MacOSX OpenGL adapted to DynamicLibraryBundleInfo. - X11GLXDynamicLookupHelper -> X11GLXDynamicLibraryBundleInfo - Remove all path from lib names. - GL order: libGL.so.1, libGL.so, GL - shallLinkGlobal: true -> to server some 'old' DRI systems -> http://dri.sourceforge.net/doc/DRIuserguide.html - shallLookupGlobal: false - Try both : glXGetProcAddressARB and glXGetProcAddress - Using bootstrap: GLX.glXGetProcAddress(long glxGetProcAddressHandle, String glFuncName) Found the issue with LIBGL_DRIVERS_PATH, ie if not set no valid GL instance can be found (ie ATI fglrx/DRI). This may happen if using a differen user than the desktop user for whom the env var is set within some /etc/X11/Xsession.d/ script. Enhancements: ============= GLBufferSizeTracker: Use IntIntHashMap and add DirectState size tracking. GLBufferStateTracker: Use IntIntHashMap. GLStateTracker: Use IntIntHashMap. GLDynamicLookupHelper: More generic (global loading/lookup and GetProcAddress function name list), remove redundant code. FIXME: MacOSXCGLDynamicLookupHelper: - Not tested - Not using NSImage lookup anymore as recommended by OSX API Doc, so dlsym is used always (to be tested) WindowsWGLDynamicLookupHelper: - Not tested GLX/WGL/CgGL is all runtime-dynamic as now, ie loaded and looked-up at runtime, no compile time dependencies to GL anymore, nor a need to specify CgGL. Split up WGL in GDI and WGL, to allow proper dynamic runtime linkage of OpenGL32 while using static binding to GDI32 NEWT events generated by native code are enqueued and not send directly. This should ease locking mechanisms .. if any are necessary. NEWT: More platform specific code moved to *Impl method, simplifying the generic code of the superclass and impl protocol. Cleanup: ========= Replace all InternalBufferUtil's with com.jogamp.common.nio.Buffers Removed all InternalBufferUtil's from repository Removed GLContextImpl notion of 'optimized' surface locking, where the surface gets unlocked during makeCurrent/release. This just makes no sense and would impact multithreading in a horrible way. --- make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java | 34 ++++++++++++++++++---- 1 file changed, 29 insertions(+), 5 deletions(-) (limited to 'make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java') diff --git a/make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java b/make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java index bceb12fe5..aa176738a 100644 --- a/make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java +++ b/make/config/jogl/gl-impl-CustomJavaCode-gl4bc.java @@ -308,19 +308,20 @@ public java.nio.ByteBuffer glMapBuffer(int target, int access) { if (__addr_ == 0) { throw new GLException("Method \"glMapBuffer\" not available"); } - int sz = bufferSizeTracker.getBufferSize(bufferStateTracker, - target, - this); + int sz = bufferSizeTracker.getBufferSize(bufferStateTracker, target, this); + if (0 == sz) { + return null; + } long addr; addr = dispatch_glMapBuffer(target, access, __addr_); - if (addr == 0 || sz == 0) { + if (0 == addr) { return null; } ARBVBOKey key = new ARBVBOKey(addr, sz); ByteBuffer _res = (ByteBuffer) arbVBOCache.get(key); if (_res == null) { _res = newDirectByteBuffer(addr, sz); - InternalBufferUtil.nativeOrder(_res); + Buffers.nativeOrder(_res); arbVBOCache.put(key, _res); } _res.position(0); @@ -330,6 +331,29 @@ public java.nio.ByteBuffer glMapBuffer(int target, int access) { /** Encapsulates function pointer for OpenGL function
