Though, the Unity code doesn't seem to use HSplitter or VSplitter. Also, it doesn't call QueueRelayout on any InputArea objects, which seems to be the only other way for an InputArea object to be put on the layout queue. Btw the parent object of an object of type InputArea is a Layout object comment at Area.cpp:603 is indeed wrong, since UnityWindowView::GetBoundingArea() has a counterexample. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337244 Title: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout() To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/1337244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1337244] Re: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout()
It seems like FloatingWindow is being added to the queue with QueueObjectLayout in FloatingWindow.cpp, but might not be removed from the queue before it's deleted. Its ancestor Area has the same potential issue, as well. So, moving the RemoveObjectFromLayoutQueue call in View and Layout destructors to their common ancestor Area's destructor (as in the attached patch) should fix that issue (and this bug, unless something else is overwriting the objects in that queue). ** Patch added: nux-remove-area-from-layout-queue.patch https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1337244/+attachment/4164791/+files/nux-remove-area-from-layout-queue.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337244 Title: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout() To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1337244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1337244] Re: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout()
Actually, since View is FloatingWindow's indirect base class, and since InputArea (which is the only other class derived from Area besides Layout) is a direct base class of View, and InputArea objects are not put on that queue, the RemoveObjectFromLayoutQueue calls in View and Layout destructors do seem to remove all queued Area objects (including FloatingWindow objects). So, the patch wouldn't fix the bug, so I've removed it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337244 Title: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout() To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/1337244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1337244] Re: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout()
However, if the parent object of an object of type InputArea is a Layout object comment at Area.cpp:603 is inaccurate (as some of the other comments there, such as the ones at :540, :576, and :596), and if InputArea objects can have HSplitter or VSplitter as parent, then they could be added to the queue at Area.cpp:521, in which case they would need to be removed from the queue in the InputArea destructor (as in the attached patch). ** Patch added: nux-remove-input-area-from-queue.patch https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1337244/+attachment/4165209/+files/nux-remove-input-area-from-queue.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337244 Title: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout() To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/1337244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

And since InputArea and Layout are the only classes derived directly from Area, and they would both have the same code in their destructors with the patch in #6, the removal code can be moved to the Area destructor, as in the attached patch. ** Patch added: nux-remove-area-from-layout-queue.patch https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1337244/+attachment/4165234/+files/nux-remove-area-from-layout-queue.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337244 Title: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout() To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/1337244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1337244] Re: compiz crashed with SIGSEGV in nux::WindowThread::ComputeQueuedLayout()
This keeps happening over and over. Looking at the resolution of the other bug, I expect the code that needs to be fixed is not here, but in the handling of some element in this queue. I suspect some element is getting deleted and the memory reused without it being removed from the queue. Here's the latest stacktrace: #0 0x in ??
