in reply to uninitialised value in hash reference

As I read this sub, the first thing you do is call the same sub recursively, with exactly the same argurmen list, unless the last element's equal to one.

I assume you meant to pull one element off the front or back of the @_ parameter array and work recursively on the remainder, but the pulling off part got forgotten. Filling up the stack can lead to strange errors, so you should fix that first.

    There's a subroutine call in there, that presumably does the @_ manipulations necessary: 
        unless ($_[$#_] eq 1){
        handle_direntries(handle_direntries_params(@_));
    }

    But since the poster didn't give us the code for handle_direntries_params(), we can only assume that it at least doesn't return @_ unchanged.
