All,
I'd like (in the somewhat distant future) for us to be able to run
Mir's tests under helgrind [1] so that we can automatically detect
races in continuous integration.
It's not going to be a short journey, as there's a fair amount of
errors to fix yet. They're mostly benign but the noise easily hides
real bugs. So in the mean time, if you write any new code that
crosses multiple threads, please try to run your individual test
cases under helgrind and check no new races are being introduced.
If we want to use helgrind seriously we should probably fix some of its
more glaring shortcomings. In particular, it doesn't understand
std::atomic and doesn't appear to understand std::condition_variable,
which means it generates a _lot_ of false positives for code that's
transparently correct.
