Re^5: A DWIM too far?

Personally I would prefer rename to fail by default with an option to overwrite. It would make my code more robust.

You'd still get the race condition, unless the underlying C API call was atomic - and we've seen that in a lot of cases this isn't the case (i.e. you'd first have to check for the file's existence, hence the race condition.)

I'd hoped that it would have been obvious that this would need to be implemented without using rename(2) :-)
