Re-allow suppressing onDetachedFromWindow Bug: 17578553 Games seem to be doing this to prevent destruction of their GL contexts, and they assume it works even if it doesn't. However, GLSurfaceView is clunky here, so while the app is doing something questionable we don't really offer a better way. For now revert back to kitkat behavior.

Revert all recent GLSurfaceView changes. Several issues have been identified that will need to be resolved carefully before we attempt to make similar changes. 1. Some applications make assumptions about the fact that all Runnables posted with queueEvent() will be executed before the next draw. Because the Choreographer may post messages in the past (due at the frame time), these Runnables were not always running at the expected time. 2. Some applications apparently hijack the GLThread and try to run their own Looper on it. This obviously won't work if we are already running one of our own. We may need to add new rendering modes or target API checks to provide an opportunity for applications to opt-in to the changes in the future.

Fix change of behavior in Looper.quit(). It seems some applications rely on Looper.quit() terminating the loop immediately without processing all messages. Rather than risk breaking them, make the safer behavior optional. Also take care to properly drain the message queue before quitting so that all of the Message instances are recycled. This may help release storage sooner in case the Looper doesn't get GC'd promptly and its remaining queue of undelivered messages sticks around. Improve docs on runWithScissors.

rework GLSurfaceView so it can use the choreographer GLSurfaceView will now automatically use the Choreographer to schedule render updates on VSYNC. This happens only in RENDERMODE_CONTINUOUSLY.

When pausing we want to do three separate things, in order: + release the EGL surface + optionally release the EGL context + optionally terminate Egl Previously we would only do these things if we had an EGL surface.

Make GLSurfaceView handle eglSwapBuffers errors more robustly. A careful reading of the EGL spec, as well as experience with many different EGL drivers, has shown that it is error prone to attempt to discriminate between different error conditions. We now treat any error besides EGL_CONTEXT_LOST as an indication that the EGL context is in a bad state, most likely due to the window manager having removed the underlying surface flinger surface. In addition, we changed the way we deal with this kind of error: Previously we would ignore the error and keep rendering. But if the EGL context and surface has become invalid, it would be better to stop drawing. We now stop drawing until the surface view surface is recreated. See b/6032663 for an example of this problem affecting the GMM app, but note that GMM is using their own version of GLSurfaceView, so this change won't help them directly. They'll have to make a similar change to their version of GLSurfaceView. Change-Id: Iffe3e1e3a3c7a91d03140fd34391eadeaecf777e Signed-off-by: Jack Palevich <jackpal@google.com>

Fix potential GLThread / GLSurfaceView memory leak. Until now a leak was possible under the following scenario: Create a GLSurfaceView Register a renderer (this automatically starts a GLThread). Discard the GLSurfaceView without installing it in the view system. This scenario can occur when a device is rotated rapidly from orientation A to orientation B to orientation C. In that scenario, orientation B's GLSurfaceView might be discarded without ever being attached to a window. If this issue had been identified before GLSurfaceView had clients, one possible fix would have been to delay the construction of the GLThread until the GLSurfaceView was attached to a window. Unfortunately, it's too late, and so making that change would lead to observable changes in behavior, possibly breaking some clients. Instead, fixed by making GLThread and EGLHelper static classes that hold onto a weak reference to the GLSurfaceView. This allows the GLSurfaceView to be garbage collected when it is no longer used, even if the GLThread is active. GLSurfaceView's finalize method will manually stop the GLThread if it is still running when the GLSurfaceView exits. Part of this change was to remove the Renderer reference from GLThread, because Renderer is a user-supplied class that could contain a reference chain that points back to the GLSurfaceView. Fixes b/5606613 "GLSurfaceView that's never added to a window will leak threads and views, can leak activities" Change-Id: Iafdc329eb6e9e40062358e7c119f5547ffe23d5e

fix an issue where the screen could be stale after a surface size change some GLES drivers dequeue buffers before a frame is started (which is allowed), which can cause a that frame to be rendered into a buffer of the wrong size. Such buffer will be ignored by the compositor. If the application draws only once after a size change, the screen might stay in this stale state. this can be avoided by telling the GL driver to purge all its pending buffers, which is done by making the surface not current and then current again. this solution is specific to android, but acceptable because handled solely in the framework.

Fix deadlock when switching between two GLSurfaceViews Some devices only support a single active EGL context. On those devices, when a second activity that uses a GLSurfaceView is started in the same process, the second activity can potentially hang in GLSurfaceView.onWindowResize waiting for its GLSurfaceView render thread to draw a frame. The second activity's render thread is waiting to acquire an EGL context, but the first activity's render thread doesn't know it should release the EGL context. The fix is to detect the potential hang, and ask the first activity's render thread to release the EGL context. Change-Id: Ibb342c68772297744c973bcf5010581cd132db67

Quietly handle EGL_BAD_NATIVE_WINDOW errors We believe these errors happen when the window manager has told surface flinger to close the native window. If this error happens while we are creating the EGL surface we exit the render loop (and therefore exit the render thread.) If the error happens while swapping the surface we ignore it. In either situation, we expect that the application is about to be shut down by the window manager, so it should not be necessary to try and recover from the error.

GLSurfaceView pause and resume now synchronize with the GLThread. We used to just set the mPaused state and return, now we wait until the rendering thread signals that it has noticed the change in pause state. This makes Pause/Resume more consistent with other UI-thread-to-GLThread event communication. This change was made in the hope of fixing some race conditions observed in monkey testing.

Improve our EGL management when pausing / resuming. We now release the EGL context when pausing. This is required to reduce the chance of running out of contexts on devices which support a limited number of active EGL contexts. Someday we may implement a global EGL context manager that will allow us to let EGL contexts persist until another activity needs an EGL context. But for now, without such a manager, we take the conservative approach. Separately, we now terminate EGL when pausing on Sapphire. This is a requirement of the Sapphire OpenGL driver.

Improve eglSwapBuffers error handling. We now distinguish EGL_CONTEXT_LOST errors from other kinds of errors. We return "true" if the swap completes successfully, "false" if the swap fails due to EGL_CONTEXT_LOST, and throw a RuntimeException if the swap fails due to any other cause. If eglSwapBuffers succeeds, we now avoid calling eglGetError at all, which means we avoid clearing any EGL errors that might already have been pending before eglSwapBuffers is called.

Fix inverted release-EGLContext-on-pause logic. This works around a bug in the "Q3Dimension MSM7500" driver. That driver only supports a single active EGLContext, so we must release and restore the EGLContext when pausing and unpausing. Unfortunately the test for deciding whether to release the context was inverted. We were releasing the context on every device besides the MSM7500 devices, which was a performance drain, and we were not releasing the context on the MSM7500, which meant the underlying driver bug was not worked around. Now we release the EGL context when pausing only on the devices that have the bug.

Decouple the EGL context lifetime from the EGL surface lifetime. The EGL context is now preserved when possible. Previously we would destroy it whenever the EGL surface was destroyed. Preserving the EGL context preserves loaded textures and VBO resources.

Fix bug 2325244 screen turns black for a brief period of time The problem was a black first frame when creating a surface, or a garbage frame when the surface was resized. The cause was lack of synchronization between the render thread and the UI thread. The UI thread would typically return before the render thread had a chance to draw its first frame. The fix was to make the UI thread wait until at least one frame had been rendered by the rendering thread. The waiting is done in the surfaceChanged method because we know that surfaceChanged will be called in both the surface created and surface changed cases.

Extend GLSurfaceView to make it easy to create an OpenGL ES 2.0 context Provide a new method, GLSurfaceView.setEGLContextClientVersion. Clients call this method to define which level of OpenGL ES support they want. This method only affects the default behavior of GLSurfaceView. If clients have supplied their own EGLContextFactory or EGLConfigChooser then they are on their own if they want to create an OpenGL ES 2.0 context. This API is currently hidden. Update the gl2_java test to use this new API. Update the gl2_java test's AndroidManifest.xml file to indicate that it requires OpenGL ES 2.0.

More GLSurfaceView cleanup. + The mDone flag is now a pair of flags: mShouldExit and mExited. The problem with mDone was that it meant "had been asked to exit", but was being used by some observers as "had exited". Using two variables means that observers can observe either "had been asked to exit" or "had exited", as they prefer. + Simplyify where we check for mShouldExit. We now check for it at the top of our innermost guardedRun while loop. + requestExitAndWait now waits for mExited to be set to true to know that a thread has exited, rather than using join(). This means we can use wait() for the check, which releases the sGLThreadManager monitor, avoiding a potential deadlock. + move the event queue into the sGLThreadManager monitor. This avoids having to acquire two locks in order to enque/deque events, which also avoids the potential for lock ordering deadlocks. + Simplify the event dequeueing code. We now deque one event each time through the main GLSurfaceView loop. Events still have priority over rendering, so there isn't any semantic change, it just cleans up the code. + Avoid trying to acquire an egl Surface if we're paused. + To simplify reasoning about the code, call sGLThreadManager.notifyAll() in every case where we modify one of the variables that's protected by the sGLThreadManager monitor. It would be slightly more efficient to only notify when we change variables that could cause a thread to wait(), but then we would have to redo our analysis every time we change any code. + Clean up the logic for creating the EGL surface and then calling the renderer's onSurfaceCreated / onSurfaceChanged methods. + Implement work-around for bug 2263168 "Need to draw twice after screen rotation..."

Fix multi-lock ordering issues in GLSurfaceView There were potential deadlocks between the per-GLThread monitors and the GLThreadManager monitor. To avoid these deadlocks we now use a single monitor for both the GLThreadManager state and the per-GLThread state. Converted GLThreadManager's semaphore into the equivalent synchronized-wait-notifyAll code. This enables us to wait for either mDone, or user events, or the EGL surface with a single "wait()". Simplified the logic used to acquire and release the EGL surface. The EGL surface is now only requested while the surfaceFlinger surface is acquired. Removed the "egl surface stealing" policy we had recently inserted. It's not needed now that we reliably quit when requested. Pulled user event processing outside of the GLThreadManager monitor so that we don't call any potentially-long-running code while inside the monitor. This should help with bug 2228262.

Allow a GLThread to release and reacquire the EGL Surface as needed. We currently only allow one GLThread to have an active EGL Surface at a time.(This may be lifted in the future, when EGL and GL are reentrant.) Prior to this change we would enforce this rule by having older GLThreads quit when a new GLThread started. That had the drawback of leaving the older GLSurfaceViews in a zombie state -- their GLThreads would be gone. We now enforce this rule by just releasing and reacquiring the EGL surface context as needed. Specific changes to the code: created private helper methods - startEgl and stopEgl to help manage starting and stopping EGL. Move the calls to sGLThreadManager start and end from the outermost run method into the startEgl / stopEgl methods. Reworked the wait loop to handle starting and stopping EGL as needed. needToWait() gets simpler -- just looks at current status. sGLThreadManager.shouldQuit was replaced by shouldHaveEgl. This is another step in fixing bug 2228262.

Fix stupid bug in GLThreadManager implementation. The code intended to copy the old value of a field, before the field was updated. However, what the code was actually doing was copying the new value of the field, after the field was updated. The fix was to move the copy to before the update. This is work towards fixing bug 2228262

Improve GLSurfaceView to avoid deadlocks and race conditions. This is work towards fixing bug 2228262 Specific issues fixed by this change: + GLThread names now include the thread id, making it easier to tell one GLThread from another. + A private final static boolean LOG_THREADS can be set to true at compile time to print out thread-related trace information, helpful for debugging GLSurfaceView behavior. This static defaults to "false". + Changed calls to "notify" to "notifyAll" to make the code more robust in case more than two threads are blocked on the same monitor. + Add a GLThreadManager to help manage the transition to a new GLThread. Currently only one GLThread can be active in an address space. When the second thread starts up, the GLThreadManager helps the old GLThread to shut down, + Make sure we stop waiting for dead GLThreads. This is done by adding checks for a variable mDone being true to our monitor wait loops. And we use a "finally" clause at the end of GLThread.run() method to set mDone and notifyAll any wait loops.
