For this purpose, I've set up a small svn repo
with everything to run the test
easily. There's no dependency, you just need pthread, gcc and sh.
Here's how to run the test:
svn co http://svn.samalyse.com/misc/rbtest
cd rbtest
make test
It tests the ringbuffers from (all included) jack, portaudio and portaudio
without barriers. That can take up to 6 minutes. It has to be a bit long due to
the probabilistic nature of failures.
LAUsers could you please run this test on various architectures? Especially
PowerPC single-cpu and SMP, x86 single-cpu, SMP, in various flavors, etc...
