output overflow should not trigger 'RUN-ERROR' #89

Closed eldering closed 10 years ago

eldering commented 10 years ago

When a team solution overflows the output limit, it will be terminated with a RUN-ERROR. It would be better if this just produces a wrong-answer or maybe timelimit.

Proposed solution: when output limit is N, filter with 'head -n N+1' and test and report output limit exceeded in jury interface.

Output redirection currently occurs in the run script that is run within the runguard chroot environment; head need not be available there.

A possible solution is to redirect the submission std{out,err} through runguard and let runguard filter these a la head. Runguard is passed the filelimits anyways.
