---------------
mir (0.15.0+15.10.20150818-0ubuntu1) wily; urgency=medium

  [ Daniel van Vugt ]
  * New upstream release 0.15.0 (https://launchpad.net/mir/+milestone/0.15.0)
    - ABI summary: Only servers and graphics drivers need rebuilding;
      . Mirclient ABI unchanged at 9
      . Mirserver ABI bumped to 33
      . Mircommon ABI unchanged at 5
      . Mirplatform ABI bumped to 9
    - Enhancements:
      . Add support for Mir-on-X11.
      . Latency reduction optimizations (around ~15ms reduction in total):
        Reduced input event resampling latency by 5ms. Reduced output latency
        (in system compositors) by around 10ms with the introduction of
        "predictive bypass". And we're not finished; future Mir releases
        should reduce latency further.
      . Introduced a python3-based Mir performance framework.
      . Lots of preparation for an architectural overhaul of buffer swapping,
        required in the least to support future optimizations like nested
        bypass.
      . Added a new cursor: crosshair
      . Added support for 15/16-bit client pixel formats ("high colour").
      . Added a new client function to make picking the right pixel format
        for a given EGLConfig super simple: mir_connection_get_egl_pixel_format
      . Added application-not-responding detection
      . Added client API for specifying input region shape.
      . Fixed the remaining threading flaws identified by ThreadSanitizer and
        turned it on permanently for all continuous integration in future.
      . Added support for relative pointer motion events (e.g. for gaming).
    - Bug fixes:
      . Fix focus issues breaking autopilot tests entering text (LP: #1468029)
      . Fix mir tests failure on armhf with GCC5 (LP: #1478213)
      . mir_buffer_stream_swap_buffers_sync can hang constraints (LP: #1479899)
      . Loading libmirclient.so twice leads to a segfault in libmirprotobuf.so
        (LP: #1391976)
      . Visible corruption in SDL apps (LP: #1460149)
      . MultiThreadedCompositor::destroy_compositing_threads hangs/deadlocks on
        shutdown or display reconfiguration  (LP: #1471909)
      . ctest/"make test" reports 100% tests pass even when some fail.
        (LP: #1472911)
      . Mir server crashed - GLib-CRITICAL **: g_source_get_context: assertion
       'source->context != NULL || !SOURCE_DESTROYED (source)' failed
        (LP: #1473869)
      . USC crash on multimonitor unplug [std::exception::what: error during
        hwc prepare()] (LP: #1474891)
      . [regression] Input focus delay after switching app back into focus
        (LP: #1480654)
      . GLibMainLoopTest.propagates_exception_from_server_action fails with
        GCC 5 in armhf (LP: #1482274)
      . [enhancement] Mir lacks relative mouse support (LP: #1276322)
      . ShmBuffer ignores pixel_format (LP: #1424909)
      . Fullscreen bypassed clients stutter with double buffers when other
        clients are running (LP: #1447896)
      . [regression] Demo servers crash on start-up if MIR_ENABLE_TESTS=OFF
        (LP: #1439078)
      . [regression] The software cursor has a rectangular shadow around it
        in mir_proving_server (LP: #1447911)
      . TestClientCursorAPI.cursor_passed_through_nested_server fails
        intermittently (LP: #1462088)
      . [enhancement] Add support for high colour (15/16-bit colour) clients
        (LP: #1469673)
      . android-input logs are not flushed as soon as they happen (LP #1470204)
      . Android: rotated display config not applied when an external monitor
        is hot-plugged (LP: #1471858)
      . [regression] Clients are blocked in swap buffers when the screen turns
        off (LP: #1475120)
      . [regression] Some Mir EGL demos don't get bypassed any more in
        fullscreen (LP: #1480755)
      . [regression] Multi-finger gestures are often not detected as finished

      . Connection error when no client-platform (drivers) installed is
        confusing (LP: #1473268)
      . Compositor report shows overlays ("bypass") is never used by
        mir_proving_server on Android, even for fullscreen surfaces
        (LP: #1474231)

Title:
  Connection error when no client-platform (drivers) installed is
  confusing

Status in Mir:
  Fix Committed
Status in mir package in Ubuntu:
  Fix Released

Bug description:
  If you don't have a client-platform installed the error message during
  connection implies the Mir socket is missing, i.e.

  $ mir_demo_client_basic -m /tmp/mir_socket 
  Failed to connect to server `/tmp/mir_socket': No such file or directory

  I'd expect error messages like:
  Failed to connect to server `/tmp/mir_socket': Unable to open Mir socket (No such file or directory)
  Failed to connect to server `/tmp/mir_socket': Unable to access client platform (No such file or directory)
