This bug was fixed in the package mir - 0.6.0+14.10.20140811-0ubuntu1

mir (0.6.0+14.10.20140811-0ubuntu1) utopic; urgency=medium

  [ Cemil Azizoglu ]
  * New upstream release 0.6.0 (https://launchpad.net/mir/+milestone/0.6.0)
- mirclient ABI unchanged at 8. Clients do not need rebuilding.
- mirserver ABI bumped to 24. Servers need rebuilding, but probably don't
  need modification:
  . Host lifecycle event listener for nested servers introduced.
  . Add query function to BasicSurface.
  . The (deprecated) function the_ipc_factory() is now removed.
  . Removed legacy support for overriding the focus controller or the
frontend shell.
  . Added support for a common type for managing fd's.
  . Moved testdraw library to examples directory.
  . Added support for droping stale frames when a surface becomes exposed.
- Enhancements:
  . Split underlying data transport out of MirSocketRpcChannel.
  . Introduced two new client-side functions : mir_surface_get_focus and
mir_surface_get_visibility.
  . Added symbolic names for cursors.
  . Made shared code a true shared library.
  . Provide linker scripts to control symbols exported by [mesa|android]
libmirclientplatform.
  . Correct xcursor loader test to fail properly instead of segfaulting.
  . Make mir::Fd type copy constructible.
  . Miscellaneous packaging related enhancements.
  . Miscellaneous build related enhancements.
  . Added automated test cases for detecting ABI breakage.
  . examples/fingerpaint: Enable frame dropping so it's faster and more
responsive.
  . mirprotobuf folded into new libmircommon.
  . Don't propagate exceptions to graphics driver code.
  . Dropped unused/minimally used dependencies : boost-filesystem,
boost-thread, boost-chrono, boost-regex.
  . platform: provide support for customizing Mir's behavior when a
fatal_error occurs.
  . Expose an interface for touch visualization.
- Bugs fixed:
  . Mir servers crash with SIGABRT - assertion failed at
buffer_queue.cpp:136 - !pending_client_notifications.empty()
(LP: #1335481)
  . [regression][hammerhead] Mir fails to start on Nexus 5  10 as it
fails to turn vsync signal on (LP: #1345533)
  . [qtcomp] Random crash in Mir input when running AP tests: [terminate
called after throwing an instance of '...' what(): assign: File exists]
when constructing a mir::AsioMainLoop::FDHandler (LP: #1346952)
  . CI builds fail when trying to install libmircommon-dev (LP: #1348518)
  . [regression] Mir 0.6 GL clients crash immediately on startup (Mesa is
trying to use X11 instead of Mir) (LP: #1350163)
  . qmlscene crashed with SIGSEGV in _M_release() on quit (LP: #1342694)
  . Clients cannot create surfaces when the screen is off (LP: #1344024)
  . The packaging of headers and libraries is confused (LP: #1347522)
  . [regression] Intermittent CI failure in
ClientLibrary.receives_surface_dpi_value (LP: #1348095)
  . Installing mir-demos also unexpectedly installs *-dev packages
(LP: #1297100)
  . mir_unit_tests: XCursorLoader.loads_cursors_from_testing_theme crashes
on N4 (LP: #1342029)
  . [performance] Mir is spending at least 8% of its time in
 __android_log_print() (LP: #1343074)
  . [performance] Mir demo shell spends ~12% of its time in vector
allocation under DemoRenderer::tessellate_*() (LP: #1349698)
  . mir_client_library_debug.h functions do not have C linkage
(LP: #1349742)
  . mir client API is missing getters for some surface attributes
(LP: #1336553)
  . Building Mir outputs lots of warnings about Android logging functions
in 3rd_party/ (LP: #1348467)
  . The shared code should be a shared library (LP: #1341502)
  . Finish the removal of mirprotobuf library (LP: #1351133)
  . Release overlay buffers when screen is turned off (LP: #1350961)
  . mir_demo_server_shell --disable-overlays false renders incorrectly
on android (partial fix for LP: #1348330)
  . Remember to honor MIR_ENABLE_TESTS and not emit tests if it's disabled
(LP: #1352800)
  . Make it easier to separate command line options used by Mir from those
used elsewhere (LP: #1351255)
  . Expose create_native_platform in libmirplatformgraphics.so
(LP: #1353658)
  . Add versioning and pkg config to libmirplatform (LP: #1293944)

[Touch-packages] [Bug 1342694] Re: qmlscene crashed with SIGSEGV in _M_release() on quit

2014-07-17 Thread Alan Griffiths
The problem is a cleardown sequence difficulty.

mirclient had some non-trivial static duration data that was accessed
when connection_release was called.

This is fine for all the tests and examples in Mir. But platform-api
delays calling connection_release until later with the result that
access to dead objects was possible.

The linked branch changes one of the mir examples to do a similar thing
and updates the client library to explicitly manage the lifetime of the
required data.

  Given the app:

  import Ubuntu.Components 1.1

  MainView {
applicationName: blah

Button {
  anchors.centerIn: parent
  text: Quit
  onClicked: Qt.quit()
}
  }

  And launching it with:
  $ qmlscene test.qml 
--desktop_file_hint=/usr/share/applications/webbrowser-app.desktop

  on the phone (sorry for the webbrowser part, bug #1325984).

  On pressing Quit, the app segfaults.
