Subject [jira] [Commented] (DERBY-5824) testOSReadOnly fails with k.AssertionFailedError: expected an error indicating the db is readonly on HP java 1.6
Date Tue, 27 May 2014 14:13:01 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14009698#comment-14009698

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
