This bug was fixed in the package mir - 0.2.0+14.10.20140605-0ubuntu1 --------------- mir (0.2.0+14.10.20140605-0ubuntu1) utopic; urgency=medium [ Daniel van Vugt ] * New upstream release 0.2.0 (https://launchpad.net/mir/+milestone/0.2.0) - mirclient ABI unchanged, still at 7. Clients do not need rebuilding. - mirserver ABI bumped to 20. Shells need rebuilding. . Cursor::set_image() parameters changed. . Display::the_cursor() renamed to Display::create_hardware_cursor() . Platform::create_display() requires a new parameter; gl_program_factory . Renderable::buffer() no longer accepts any parameter at all. Multi- monitor frame sync is guaranteed in other ways now. . Scene::generate_renderable_list() renamed to renderable_list_for(id) where id is an opaque compositor ID of your choosing. . Scene::set_change_callback() replaced by the more generic: add_observer() and remove_observer() functions. . Added default implementation for SceneObserver. . SessionCreator renamed to ConnectionCreator. . ConnectedSessions renamed to Connections. . ProtobufSessionCreator renamed to ProtobufConnectionCreator. . SessionAuthorizer: pid_t parameters replaced by SessionCredentials. . Massive architectural changes to Input-everything. . Surface no longer implements Renderable, but emits one via compositor_snapshot(). . Pass the full renderable list to Renderer::render(). . Graceful handling of exceptions thrown from server threads. . Clarify size position interfaces in the Surface classes. . Plumbing for trusted sessions. . Allow posting and managing custom main-loop actions. . Timer extension. . Identify client process when client connects to Mir not when socket connects. . Use the ServerActionQueue for display config. . Recomposition signal moved to the MultiThreadedCompositor. . Make timer service replaceable. . Clarify assumptions about how many buffers a client can fill without blocking. . Introduce EmergencyCleanup interface. - Demo shell enhancements: . You can now change graphics modes on the fly using Ctrl+Alt+(-/=). To reset to the preferred mode use Ctrl+Alt+0. . The above mode changing as well as existing screen rotation keys (Ctrl+Alt+arrows) are now per-display; only applied to the monitor the mouse pointer is on. . New shell controls documented. - A new testing category, performance test, was introduced. It currently runs glmark2-es2 and compares the result to a minimum threshold. - MIR_VERSION_MINOR is tied to MIRSERVER_ABI in the sense that a change in the former now requires dependent projects that a rebuild is necessary. - SwitchingBundle was replaced by BufferQueue. - Expand credentials to include uid/gid for session authorizer. - Bypass control is now Mesa-specific and tied to the command line options. So the environment variable MIR_BYPASS has changed to MIR_SERVER_BYPASS. - Ongoing architectural changes in the compositor/renderer logic to prepare for overlay support, and to reduce locking overhead. - Made InputDispatcher replaceable. - Progress made on new cursor interfaces with the end goal of client and toolkit control of the mouse cursor appearance. More work required. - Updated cross-compile docs and scripts to support the latest utopic devel images. - Replaced uses of android::sp with std::shared_ptr. - Client cursor API infrastructure. - Enabled eglSwapInternal(0). - Make texture caching algorithm reuseable. - Add a DPI surface attribute. - Exclude arm64 from build. - Bugs fixed: . Mir doesn't install cleanly if docs are not built. (LP: #1304271) . Unity-system-compositor crashed [what(): Failed to set DRM crtc]. (LP: #1294510) . [regression] unity8 fails to load libmirplatformgraphics (undefined symbol: _ZN3mir8graphics9GLProgramD1Ev). (LP: #1317200) . [regression] unity8 rendering artifacts. (LP: #1317260) . [regression] [BufferQueue] BufferQueueTest.compositor_never_owns_client_buffers occasionally crashes with: what(): unexpected release: buffer was not given to compositor. (LP: #1317801) . Hardcoded size for serialization buffers is neither reliable nor secure. (LP: #1320187) . [regression] [BufferQueue] mir does not composite last client given buffer. (LP: #1321861) . [regression] stale frame on seen on greeter when screen is unblanked and toolkit/apps are laggy/throttled. (LP: #1321886) . [regression] [BufferQueue] current_buffer_users vector memory usage grows unbounded. (LP: #1317808) . Intermittent test failures in CustomInputDispatcherFixture.custom_input_dispatcher_receives_input. (LP: #1318587) . [regression] [BufferQueue] Race condition in BufferQueue::compositor_acquire could underflow shared_ptr refcount and delete prematurely, crash. (LP: #1318632) . Overflow in mir::client::rpc::MirSocketRpcChannel::receive_file_descriptors as reported by address sanitizer. (LP: #1320821) . [regression] [input] Scroll events are now always zero: event.motion.pointer_coordinates[0].vscroll. (LP: #1321077) . CI failures in CustomInputDispatcherFixture .custom_input_dispatcher_gets_started_and_stopped. (LP: #1321215) . [regression] Mir cursor vanishes after switching VTs. (LP: #1323225) . Server library links against libmirserverlttng. (LP: #1323317) . [DRM/GBM] Killing (or crashing) Mir often leaves the screen blank and difficult to recover. (LP: #1189770) . Frame rates of GL clients are limited to 60Hz on Android, even with swapinterval=0. (LP: #1206400) . mir_surface_is_valid(NULL) crashes instead of returning false. (LP: #1248474) . [regression] tests/unit-tests/shell/test_mediating_display_changer.cpp is not compiled and executed. (LP: #1312832) . Android platform does not reset the compositionType to HWC_FRAMEBUFFER before prepare() on every frame. (LP: #1314399) . The client process is identified when the socket connects, not when the client connects to Mir. (LP: #1314574) . [regression] Clients can't acquire multiple buffers any more. (LP: #1315302) . [regression] Enabling SwitchingBundleTest DISABLED_synchronous_clients_only_get_two_real_buffers now crashes with no usable stack trace. It used to only fail. (LP: #1315312) . [regression] [BufferQueue] double-buffered client freezes as no buffer is returned on compositor_release. (LP: #1319765) . Uninitialized mem in OutputBuilder.hwc_version_11_success. (LP: #1312867) . [enhancement] In the tests make it possible to get a DefaultConfiguration initialized from the command line (LP: #1316987) . ci train blocked due to missing arm64 libandroid-properties-dev.
