There's a story behind the case insensitive directory fixes, and lessons
to be learned.
When I was discussing with the developer who did the implementation, I
noted that fstests should already have tests.
However, it seems I neglected to tell him to make sure the tests
actually run. So, there's a lesson here, and since inadequate testing
keeps coming up, let me state it now:
It is _not_ enough to simply rely on the automated tests.
You have to have eyes on what your code is doing. That means that until
you've thoroughly Familiarized yourself with the code you're working on
and the test suites, you need to look - with your eyes - and confirm
that the tests are doing what you think they're doing and your code is
doing what you think it's doing.
If you're not 100% sure that your code is doing what you think it's
doing, it's your responsibility to dig in and verify - add printks,
tracepoints, counters, whatever it takes.
Automated test infrastructure is a backstop because there are times when
we are all forgetful and miss things.
You have to run your code locally, and look at what it does. I've
provided good tools for this. If you're working on my code, make sure
you're using them.
