  Nested server segfaults when a fullscreen client starts

  Using Mir 0.26.0 (zesty release):

  The client dies:

  Start your nested server with --nested-passthrough=OFF

then hit the more recent regression bug 1661521.

  Start your nested server with --nested-passthrough=OFF
  Which works on the 0.26.0 release, but not on anything newer because you'll 
then hit the more recent regression bug 1661521.

mir (0.26.1+17.04.20170209.1-0ubuntu1) zesty; urgency=medium

  * New upstream release 0.26.1 (https://launchpad.net/mir/+milestone/0.26.1)
- ABI summary:
  . mirclient ABI unchanged at 9
  . mirserver ABI unchanged at 43
  . mircommon ABI unchanged at 7
  . mirplatform ABI bumped to 15
  . mirprotobuf ABI unchanged at 3
  . mirplatformgraphics ABI bumped to 12
  . mirclientplatform ABI unchanged at 5
  . mirinputplatform ABI unchanged at 6
  . mircore ABI unchanged at 1
- Enhancements:
  . Support for MirBuffer API that allows for better management of
hardware/software buffers.
  . Support for MirPresentationChain API that allows better control
over {de}queueing of individual buffers {from}to the server.
  . Interim support for MirRenderSurface API that provides a unit of
renderable for lower level content such as MirBufferStreams and
MirPresentationChains, etc.. MirRenderSurface API is marked
deprecated as it (and the relevant entry points) will be renamed to
MirSurface before general availability. It will initially be used for
revamping support for EGL drivers.
  . Synchronous version of mir_prompt_session_new_fds_for_prompt_providers()
API (mir_prompt_session_new_fds_for_prompt_providers_sync()) added for
convenience.
  . Better name for MirPersistentId-->MirWindowId. MirPersistentId has now
been deprecated.
- Bugs fixed:
  . [regression] Unity8 stutters constantly (like half frame rate).
(LP: #1661128)
  . mir 0.26 - spinner loading animation, minimize, maximize too fast.

[Touch-packages] [Bug 1661508] Re: [regression] Nested server segfaults or rapidly logs exceptions when a fullscreen client starts [in mir_presentation_chain_set_dropping_mode ... std::exception::what

2017-02-03 Thread Kevin DuBois 
Why this crashes sometimes and other times spams is that wait_for_all()
is sometimes called on a nullptr MirWaitHandle. The first thing that fn
does is grab a lock. Some libc's seem smart enough to recognize that the
memory isn't there and throw system_error, but its pretty conceivable
that this could segfault if libc wasn't able to detect the memory issue
and throw.

2017-02-03 Thread Daniel van Vugt 
As a workaround on zesty (0.26.0) you can use --nested-passthrough=OFF

However that workaround stops being useful in lp:mir and lp:mir/0.26
because it will trigger bug 1661521.

  Start your nested server with --nested-passthrough=OFF

then hit the more recent regression bug 1661521.

if it's just the same exception flood causing a crash in our release
binaries...
