[regression] Mir clients get caught in an infinite exception loop when the server goes away ("Caught exception at Mir/EGL driver boundary")

Unfortunately, being an infinite loop, no core is dumped, nothing is restarted and there's no bug report.

Oh, it's just bug 1347053. Since the fix for that we've gone from crashing to this infinite loop, but it seems like it could be basically the same problem still.

The relevant change was:

------------------------------------------------------------

Note that since the change is not in 0.6, you will instead see a crash with that series:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<(anonymous namespace)::socket_error> >'
  what(): Failed to send message to server: Bad file descriptor
ERROR: /home/dan/bzr/mir/r1817/src/platform/graphics/android/real_hwc_wrapper.cpp(60): Throw in function virtual void mir::graphics::android::RealHwcWrapper::set(hwc_display_contents_1_t&) const
Dynamic exception type: N5boost16exception_detail10clone_implINS0_19error_info_injectorISt13runtime_errorEEEE
std::exception::what: error during hwc prepare(). rc = ffffffff

I think that counts as bug 1347053 still.

Sorry, I'm not awake. It's the client looping. The server simply crashed, somewhere.

The server crash is now logged separately as bug 1353887.

The offending change just got backported to 0.6 so this bug is in 0.6 now too.

Fix committed to lp:mir/0.7 at revision 1863, scheduled for release in Mir 0.7.0

This bug was fixed in the package mir - 0.7.0+14.10.20140829-0ubuntu1

---------------
mir (0.7.0+14.10.20140829-0ubuntu1) utopic; urgency=medium

  [ Daniel van Vugt ]
  * New upstream release 0.7.0 (https://launchpad.net/mir/+milestone/0.7.0)
    - Enhancements:
      . Test suite: Reworked mechanism to override Mir client functions
      . Demo shell: Detect custom rendering (decorations) to make it
        compatible with overlay optimizations
      . Make sure to preserve fd resources until the end of the sending
        of the message
      . Add test cases and script for tracking changes to the new ABIs:
        libmircommon, libmirplatform
      . Symbols file for libmirplatform
      . Symbols file for libmircommon
      . Symbols file for libmirserver
      . Various improvements to the SessionMediator test
      . Various build related improvements
      . Print testcase output during package build
      . Abort test when InProcessServer startup fails
      . Link the integration and unit tests against the server objects
      . Add a document detailing the useful tests to run and the useful
        logs to collect when troubleshooting a new android chipset
      . Enable motion event resampling and prediction for a more responsive
        touch experience.
    - ABI summary: Servers need rebuilding, but clients do not
      . Mirclient ABI unchanged at 8
      . Mircommon ABI bumped to 1
      . Mirplatform ABI bumped to 2
      . Mirserver ABI bumped to 25
    - API changes
      . Deleted function - frontend::Shell::create_surface_for(). If you have
        the std::shared_ptr<frontend::Session> session, you can just do
        session->create_surface(params) instead to get a SurfaceId
    - Bug fixes:
      . Ensure we process lifecycle events before the nested server is torn
        down (LP: #1353465)
      . Fix race in InputTestingServerConfiguration (LP: #1354446)
      . Fix fd leaks in prompt session frontend code and tests (LP: #1353461)
      . Detect the additional things the demo shell draws on the renderable
        list and avoid calling the optimized post function if they are being
        drawn (LP: #1348330)
      . Client: Fix SIGTERM dispatch in our default lifecycle event handler
        (LP: #1353867)
      . DemoRenderer: Don't try to create a texture of width zero.
        (LP: #1358210)
      . Fix CI failures (LP: #1358698)
      . Fix build failure: "variable ‘rc’ set but not used" which happens in
        release mode when NDEBUG is set (LP: #1358625)
      . Only enumerate exposed input surfaces to avoid delivering events to
        occluded surfaces (LP: #1359264)
      . Android: do not post driver cancelled buffers (LP: #1359406)
      . Client: Ensure our platform library stays loaded for as long as it is
        needed by other objects (LP: #1358191)
      . Examples: Register the DemoCompositor with the Scene to properly
        process visibility events (LP: #1359487)
      . Mir_demo_client_basic: Don't assert on user errors like failing to
        connect to a Mir server (LP: #1331958)
      . Tests: Explicitly depend on GMock target to avoid build races
        (LP: #1362646)
