Package "mir"

  mir (0.1.8+14.04.20140411-0ubuntu1) trusty; urgency=medium

  [ Daniel van Vugt ]
  * New upstream release 0.1.8 (https://launchpad.net/mir/+milestone/0.1.8)
    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
    - mirserver ABI bumped to 18. Shells need rebuilding.
    - Server API changes affecting shells:
      . GLRenderer::tessellate() changed syntax.
      . graphics::Platform::create_display() has a new parameter allowing you
        to customize the compositor's (E)GL configutation.
      . Renderable::buffer(unsigned long frameno) is now:
        Renderable::buffer(void const* user_id). See below.
      . Renderable::should_be_rendered_in() is replaced by a more natural:
        Renderable::visble()
      . input::Surface::name() returns by value instead of reference now,
        to ensure future thread safety.
    - Switched EventHub device enumeration and hotplug to Udev. NOTE! This
      means mir_test_* can't run natively on touch devices any more without
      some setup first:
        sudo mount -o remount,rw /
        sudo apt-get update
        sudo apt-get install -y umockdev
        umockdev-run -- bin/mir_unit_tests
    - Added logging for HWC events.
    - Continued consolidation of Surface classes toward a simpler architecture.
    - Introduced "RenderableList" as the way to sample the Scene contents,
      and started using that in the default compositor.
    - Introduced physical length units and conversion (geometry::Length) in
      preparation for arbitrary DPI rendering.
    - Added some decorations to demo-shell; shadows and basic title bars, all
      anti-aliased and high-DPI scalable.
    - Multi-monitor frame sync has been redesigned to eliminate the need for
      frame number tracking.
    - Bugs (and enhancements) resolved:
      . [enhancement] Please move input detection to libudev (LP: #1237784)
      . [enhancement] Add a clamping resize mode to GLRenderer (LP: #1259887)
      . [regression] Intermittent loss of multimonitor frame sync
        (LP: #1290306)
      . [enhancement] Make GL config options configurable (LP: #1290780)
      . memcheck-test doesn't test anything when DISABLED_GTEST_DISCOVERY is
        enabled (LP: #1291876)
      . "Error opening DRM device" is always followed by "Unknown error -(some
        negative number)" (LP: #1292384)
      . Rendering/composition gets stopped early (LP: #1293896)
      . Ubuntu Touch Settings and terminal apps are not rendering correctly on
        rotate. (LP: #1294048)
      . [regression] Apps are much slower to open (LP: #1294051)
      . Settings app opens to a blank screen unless given enough time to render
        or the app is touched (LP: #1294053)
      . TestClientInput/DemoPrivateProtobuf memory leak is causing regular CI
        test failures (LP: #1295231)
      . OSK touch events "fall through" and hit surface behind them
        (LP: #1297878)
      . [enhancement] add a test for composite of last client post
        (LP: #1298596)
      . [regression] Surfaces vanish as soon as their edges touch the edge of
        screen (LP: #1301115)
  * Cherry-picked from future release 0.1.9:
    - Bug fix: mirplatformgraphics does not have boost program options in its
      symbol table (LP: #1301040)
    - Bug fix: unity8 crashed with SIGSEGV in glDeleteTextures() from
      mir::scene::GLPixelBuffer::~GLPixelBuffer() from
      mir::scene::ThreadedSnapshotStrategy::~ThreadedSnapshotStrategy()
      (LP: #1256360)

  mir (0.1.7+14.04.20140318-0ubuntu1) trusty; urgency=low

  [ Alberto Aguirre ]
  * Fix not compositing the client's last posted buffer (LP: #1294048,
    LP: #1294051, LP: #1294053, LP: #1290306) In single-display cases
    the number of ready buffers decreases after a buffer is acquired by
    the rendering operator. Determine if there will be uncomposited
    buffers before acquiring a buffer so it works for single and multi
    display use cases. (LP: #1294048, #1290306, #1294051, #1294053)

  [ Daniel van Vugt ]
  * New upstream release 0.1.7 (https://launchpad.net/mir/+milestone/0.1.7)
    - mirserver ABI bumped to 17
    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
    - Server API changes (AKA why doesn't my code build any more?):
      . Class "CompositingCriteria" has been removed. It's replaced by the more
        flexible "Renderable" interface. This also resulted in parameter
        changes for the Renderer and scene filtering classes.
      . The function "DisplayConfiguration::configure_output()" has been
        removed. Instead, please use the new mutable version of
        "DisplayConfiguration::for_each_output()" with which you can modify
        the output structure passed in on each iteration.
      . Exposed formerly private class "GLRenderer" and demonstrated how
        to override its behaviour in demo-shell. This area is under
        construction and may experience further major changes.
    - Added initial support for hardware (HWC) overlays to accelerate
      rendering and reduce power consumption. Not complete yet.
    - Screen rotation: Added mouse cursor rotation support, so you can now
      still control things on a rotated screen. Still missing rotation of
      the cursor bitmap itself.
    - Lots of fixes to support nested Mir servers (see below).
    - Major simplification to how surface size/position/transformation
      interact, making transformations much easier to manage and work with.
    - Bugs fixed:
      . ./cross-compile-chroot.sh: line 83: popd: build-android-arm: invalid
        argument popd: usage: popd [-n] [+N | -N] (LP: #1287600)
      . Key events sent to the wrong client (and delayed) (LP: #1213804)
      . Nested servers never receive input events (in their filters)
        (LP: #1260612)
      . Software clients crash immediately on nested servers - what(): Failed
        to mmap buffer (LP: #1261286)
      . MirMotionEvent lacks local coordinates. Reports only screen
        coordinates. (LP: #1268819)
      . Nested Mir crashes with - what():
        MesaNativePlatform::create_internal_client is not implemented yet!
        (LP: #1279092)
      . clients fail to find some libraries if mir installed via "make install"
        (LP: #1285566)
      . Nested server hangs with multimonitor and internal clients.
        (LP: #1287282)
      . [regression] Multi-monitor frame sync no longer works (not
        synchronized), and frames skip/jump/stutter (LP: #1288570)
      . Mir FTBFS: /usr/bin/ld: cannot find -lmirtestdraw (when cmake ..
        -DMIR_ENABLE_TESTS=OFF) (LP: #1283951)
      . nested Mir library calls next_buffer() during startup (LP: #1284739)
      . Building Mir produces lots of warnings from GLM headers about
        deprecated degrees values vs radians (LP: #1286010)
      . [enhancement] screencast of a single window (LP: #1288478)
      . Nexus4 + mir_demo_client_eglplasma starts to stutter after a while
        (LP: #1189753)
      . --host-socket documented default argument isn't used as default
        (LP: #1262091)

  mir (0.1.6+14.04.20140310-0ubuntu1) trusty; urgency=medium

  [ Kevin Gunn ]
  * Cherry-picked from future release 0.1.7:
    - Enhancement: options: Make it easier to customize DefaultConfiguration
    - Bug fix: Don't pass a parameter to bash's popd command. It doesn't expect
      one and will return an error from cross-compile-chroot.sh. (LP: #1287600)
  * New upstream release 0.1.6 (https://launchpad.net/mir/+milestone/0.1.6)
    - mirserver ABI bumped to 16.
    - Server API changes:
      . Report classes have moved to new namespaces/components. Please
        consult the server headers.
      . General clean-ups and virtual function changes affecting the ABI
        (a rebuild is required for all shells).
    - mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
    - Add new feature: Screen recording ("screencasting") as demonstrated by
      the new mir-util "mirscreencast".
    - debian: Provide platform packages managed with dpkg alternatives.
    - Add new valgrind suppressions (mostly for armhf right now)
    - tools: Add new libmirclientplatform.so to install_on_android.sh.
    - Add "mir_demo_standalone_render_overlays", which is a free-standing
      example of overlay support.
    - Proper DisplayConfiguration for the AndroidDisplay to be better
      prepared for multi-monitor Android.
    - Commenced/continued simplifying the surface class hierarchy: BasicSurface
      has now absorbed SurfaceData.
    - Dynamically load the client platform library.
    - Bugs fixed:
      . Exceptions thrown from within compositing threads were untraceable,
        resulting in a bunch of undebuggable crash reports (LP: #1237332)
      . Ensure we close drm device file descriptors on exec. (LP: #1284081)
      . nested render_surfaces fails on N4 [std::exception::what: Failed to
        compile vertex shader:] (LP: #1284597)
      . examples: correct "fullscreen-surfaces" option. (LP: #1284554)
      . Fix mutex data race reported by helgrind in integration test:
        SwapperSwappingStress (LP: #1282886)
      . scene: Return null snapshots for sessions without surfaces
        (LP: #1281728)
      . tests: Address some raciness in
        MesaDisplayTest.drm_device_change_event_triggers_handler.
        (LP: #1283085)
      . tests: Suppress spurious memory errors occuring when running the
        unit tests on armhf with valgrind. (LP: #1279438)
      . Mir shows an old frame on client startup (for Mesa GL clients)
        (LP: #1281938)
      . tests: Add expectation to validate second SessionAuthorizer method
        is called wit correct parameter. (LP: #1218436)
      . Set field "current_format" when sending a display config to the
        server. (LP: #1277343)
      . Fix crash in android devices by working around a subtle threading
        bug, use a dummy thead_local array to push the gl/egl context TLS
        into a region where the future wait code does not overwrite it.
        (LP: #1280086)
      . compositor: calling SwitchingBundle::force_requests_to_complete()
        can be a no-op when there are no requests. (LP: #1281145)
      . tests: Don't emit an "add" uevent manually when adding a device
        (LP: #1281146)
      . config: reduce size of default RPC thread pool. (LP: #1233001)
      . Clients freeze on startup if 10 or more are already running
        (LP: #1267323)
      . Fix Nexus 10 leaking FDs in the hwc prepare/set loop. (LP: #1278658)
      . Parallelize page flipping with rendering of the next frame, fixing
        stuttering observed in multi-monitor clone mode (LP: #1213801)
      . Ubuntu trusty update "glm 0.9.5.1-1" broke Mir builds. Work around the
        change. (LP: #1285955)
      . Screencast feature by compositing to offscreen buffer (LP: #1207312)
