European Salon de News, Discussion et Klatsch - 13 October | 135 comments (135 topical, 0 editorial, 0 hidden)

It's related to the "guest account" feature of OS X.

You can enable "disposable" guest account:

you log as guest
no need for passwd
you get a dynamically created home dir etc...
you can leave your screen locked for awhile, someone can log into another account while your jobs run, etc
when the guest account is finally logged off, everything he did on the computer is erased by wiping out the guest home dir (secure erase, multi pass...)

So it's also a privacy feature, some users use guest accounts for zero-history operation that go beyond simple browsing with the navigator in "private mode".

The bug seems to be, quite simply, that some coder fucked up the retrieval of the "right" user Id to delete on logoff...Instead of deleting the guest account, it deletes the newly logged user !

Now thats an almost genius level of inability.

Re: Living on the Planet (none / 0)

and of course a stunning failure of testing that it got out into the world as a live problem.

Re: Living on the Planet (none / 0)

I'm guessing they didn't have an automated test case for that - it's pretty outlandish - and few of their beta testers or developers use guest accounts, at least on the machines they installed pre-release versions on. It also depends on the details of the case where the bug manifests.

Re: Living on the Planet (none / 0)

You would have thought that would be on the list of "Things we must test, because the beta testers probably wont"

It will be now.

Re: Living on the Planet (none / 0)

That's how things get on the list.

Re: Living on the Planet (none / 0)

When in the distant past I worked in Software quality control, a lot of effort was put into working out where beta testers were more likely not to go, so where extra effort would likely be required., and guest accounts would have been right up there on the list. of course as you say, it depends what kicks this off when it happens, and errors will always get through. (The old Windows xp has 6000 errors campaign, was the result of calculating out testing time and number of lines of code)

Has an update already been provided? My snow leopard waiting period was drawing to a close.

Re: Living on the Planet (none / 0)

10.6.2 is in the pre-release phase - I'm guessing it'll be held up while a fi for this is rolled in.

Re: Living on the Planet (none / 0)

According to the register, they're aware, and working on a fix.
