Re: svn commit: rev 2288 - trunk/subversion/tests/libsvn_delta trunk/subversion/libsvn_delta

Folks, I need a bit of help here. I've come to the point where I can't
trip up the delta combiner any more, and I'd like to have independent
confirmation that it is, indeed, untrippable.

Used to be that if I ran

    random-test -n100000 2

I'd sooner or later get a combination that failed. Now this test runs
out of FILE* handles on Windows (must be a leak in the C runtime, I
can't imagine how this could happen otherwise), but doesn't fail in the
combiner.

So, I'd like to ask people to check out HEAD, compile and run this test
on as many machines as possible, and post the output. 100000 repetitions
would take about 5 hours on my box (450MHz PIII).

In the meantime, I'm letting the test run overnight in a loop with -n1000.

Thanks,
        Brane
