This looks indeed quite similar to what we currently have. Denis (whom we 
assigned to the task of improving the statistics) is new to aicas and not 
very experienced, so he'll probably take some time. But I'm quite content 
with what he did so far and expect that by the end of november we have this 
finished.

What do you do with your statistics? We use CVS to store the detailed report 
and use a brief summary as log message. We use the CVS facilities of sending 
an eMail with the log message to all developers.

We use scripts to generate a wrapping main class for each test (which is maybe 
not what the mauve developers intended, because running the test suite takes 
some time that way, but we want to be able to generate proper log files even 
in case some severe bug was found in the VM).

For the improved statistics, we plan to store the result of each single test 
class in a separate CVS'ed file, so comparing the results should be quite 
easy.

Since we use autoconf to configure the script, another VM can be easily used.

I just wanted to give you a short overview. We don't like to release the 
scripts in the state they are now, because they're just about to being 
restructured. But if you have comments or special wishes which we can easily 
adopt, this is probably the right time for it.

Maybe this discussion is off topic here. If you think so, we can continue on 
the mauve mailinglists (I just subscribed).

Thank you for the pointer. That probably explains why the call of (the POSIX C 
function) close in _javaio_close was commented out. I'll have a more 
detailled look at the matter in the next couple of days.


Cheers,

        Andy.
