Remodel OSX/CALayer Threading (commit 896e8b021b39e9415040a57a1d540d7d24b02db1): Run on main-thread w/o blocking ; Misc Changes
Commit 896e8b021b39e9415040a57a1d540d7d24b02db1 moved all native CALayer calls to the current thread to avoid deadlocks. Even though this seemed to be fine at least resource GC (release/dealloc calls) were issued very late in time, probably due to multithreading synchronization of JAWT and/or OSX API. Example: Our 'TestAddRemove01GLCanvasSwingAWT' test didn't freed CALayer resources incl. GL ctx when destroying the objects (AWT Frame, GLCanvas, ..), leading to resource starvation .. eventually. Remedy is a compromise of behavior before commit 896e8b021b39e9415040a57a1d540d7d24b02db1 and that commit, i.e. to run CALayer lifecycle methods on main-thread, but do not block! The careful part within MacOSXCGLContext.associateDrawable(..) performs the following block on main-thread: - lock the context - create NSOpenGLLayer (incl. it's own shared GL context and the DisplayLink) - attach NSOpenGLLayer to root CALayer - unlock the context Due to the GL ctx locking, this async offthread operation is safe within our course of operations. Details: - NSOpenGLContext - Context and CVDisplayLink creation at init - Call [ctx update] if texture/frame size changed - 'waitUntilRenderSignal' uses default TO value if given TO is 0 to avoid deadlocks +++ Misc Changes: - Fix object type detection: isMemberOfClass -> isKindOfClass - OSXUtil_isNSView0 OSXUtil_isNSWindow0, CGL_isNSOpenGLPixelBuffer - MacOSXCGLDrawable/MacOSXPbufferCGLDrawable: remove getNSViewHandle() method. MacOSXCGLContext uses common code to detect nature of the drawable handle. - MacOSXCGLContext/CALayer: Use safe screenVSyncTimeout values, never 0 to avoid deadlock! - JAWTWindow.invalidate: Call detachSurfaceLayer() if not done yet
