Hi! I hope you are not trying to find infinite loops and I simply misunderstood your question. Because if you are, then forget it (Turing anyone?)... Infinite loops are impossible to find (minus some few, very specific situations).
Cf. http://en.wikipedia.org/wiki/Halting_problem Cheers, Hugo Ferreira P.S. Hmmm... It seems I really read it wrong since you define that you want to stop "(after N passes or some complex criteria)". Anyway I leave the warning for future generations :) > My code does recursion loops through a couple of functions. Due to > problematic I/O input this leads sometimes to "endless" recursions and after > expensive I/O to the Python recursion exception. > What would be a good method to detect recursion loops and stop it by > user-Exception (after N passes or some complex criteria) without passing a > recursion counter parameter through all the funcs? > > Robert -- http://mail.python.org/mailman/listinfo/python-list
