pretty sure we just block in this test due to swapinterval 1 being set (and this driver will consume more buffers than other drivers)

yes, the nexus 10 driver would request enough buffers that a buffer acquire would block. The linked branch changes the test to run at swap interval 0 so there's no blockage if the compositor never consumes a buffer. (which in this case, since its not running in the test, it never would)

Fix committed into lp:mir/devel at revision None, scheduled for release in mir, milestone Unknown

mir (0.1.5+14.04.20140212-0ubuntu1) trusty; urgency=medium

  [ Kevin Gunn ]
  * Cherry-picked from future release 0.1.6:
    - frontend, shell: provide the client process ID in the shell::Session
      interface (LP: #1276704)
  * New upstream release 0.1.5 (https://launchpad.net/mir/+milestone/0.1.5)
    - mirclient ABI bumped to 7
    - mirserver ABI bumped to 15
    - Refactoring to support client-controled RPC.
    - Add an translucent server example (use sparingly, this will kill
      performance!)
    - Add workaround for Qualcomm Snapdragon 8960 driver bug.
    - android-input: Improve debug output
    - Screen rotation support half done (rotation of the screen works but input
      rotation not implemented yet).
    - Add groundwork for overlay support to take better advantage of mobile
      hardware features and optimize composition in future.
    - Add support for HWC 1.2 (Android 4.4)
    - Add groundwork for screencasting (screen recording).
    - Optimized surface resizing, significantly reducing event flooding for
      some input configurations like touch.
    - Bugs fixed:
      . Surfaces no longer visible at all on Nexus 10 (LP: #1271853)
      . mir nested server failure: what(): error binding buffer to texture
        (LP: #1272041)
      . Unity does not process events from evdev device created before unity is
        restarted (autopilot tests) (LP: #1238417)
      . mir_unit_tests can't run on touch images any more (missing
        libumockdev.so.0) (LP: #1271434)
      . chmod 777 /tmp/mir_socket is no longer sufficient for non-root clients
        to connect to a root server (LP: #1272143)
      . Nexus7(2013) flo framerate maxes out at 30fps (LP: #1274189)
      . libmirserver user is unable to #include
         <mir/frontend/template_protobuf_message_processor.h> (LP: #1276162)
      . libmirclient user cannot "#include <mir/client/private.h>"
        (LP: #1276565)
      . AndroidInternalClient.internal_client_creation_and_use hangs on Nexus
        10 (LP: #1270685)
      . Tests that use the InProcessServer bind the default socket file
        (LP: #1271604)
      . BasicConnector threads exit immediately (LP: #1271655)
      . Integration tests TestClientIPCRender.test_accelerated_render fails on
        Galaxy Nexus and Nexus4 (LP: #1272597)
      . Android backend unit-tests FTBS on amd64 (LP: #1276621)
      . Erroneous use of last_consumed in SwitchingBundle::compositor_acquire
        (LP: #1270964)
