Rick Hillegas commented on DERBY-5824:
--------------------------------------
Thanks for that analysis, Knut. That sounds like a plausible explanation of
this problem. This defect in this test probably affects all *nix platforms.
Probably Windows platforms too.
The test is trying to simulate running on read-only media. But the simulation
isn't good enough.
At a minimum, the test should be disabled if the user is the operating system's
super-user account. However, I don't know how to detect that condition inside
Java.
I recommend removing this test from the regression suite. We can flag it as a
test case which we run standalone from a non-root account when we vet releases.
Or not.
I am not terribly worried about removing this test. If the database really is
located on read-only media, then I think Derby won't be able to circumvent the
properties of the media. If Derby could, then, yes, there'd be a bug, but not
in Derby. The bug would be at the OS level beneath Derby.
What are your thoughts?
Thanks,
-Rick
