Title:
[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
Status in Mir:
Fix Committed
Status in Mir 0.5 series:
Fix Committed

Status in “mir” package in Ubuntu:

Bug description:
Steps to repro:
1. Install QtCompositor - right now from silo6, see
https://wiki.ubuntu.com/Unity8/QtComp
2. Use https://wiki.ubuntu.com/Touch/Testing to get your device set up for
running an autopilot test. That can be summarized roughly into running these
commands on your PC:
phablet-config edges-intro --disable
adb shell powerd-cli display on bright & #keeps the display on
3. Run an AP test. This one tends to expose the bug easily:
phablet-test-run -p ubuntu-html5-ui-toolkit-autopilot
ubuntu_html5_ui_toolkit
The crash we get has this stack trace:
http://paste.ubuntu.com/7836063/
"terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error>
>'
what(): assign: File exists"
Which points onto the constructor of
boost::asio::posix::basic_stream_descriptor which in case of the
default epoll reactor will call epoll_ctl to add the given file
descriptor. The error number EEXIST indicates that the file descriptor
is already inside the set.
