I'm having a problem using PLAI plus the handin server. Specifically, it looks like using (print-only-errors #t) in my code triggers the error
submit error: Error in your code -- current-directory: `exists' access denied for /home/clements/class/handin/ . I'm using this near-trivial checker: (module checker handin-server/checker (check: :language '(module plai) ;; no checks! ) ... and submitting this code: #lang plai (print-only-errors #t) In fact, I get the same error when I strip it down to simply querying the parameter, with (print-only-errors). However, it's not *all* parameters that trigger the error; I can submit code containing (current-error-port) without incident. I've taken a quick look at the code, and I can't see how setting this parameter would trigger a call to current-directory. Any ideas? John Clements
