Safeguard against DoS in Rails helper - Dogs with sunglasses - Hey, Darius here

One recent contribution to the Rails codebase caught my attention. It concerns the distance_of_time_in_words method. The fix is meant to prevent a possible Denial of Service while using this method. The contribution was brought by Stazer. I found out about the PR in the newsletter This week in Rails. The problem The distance_of_time_in_words method returns the approximate distance in time between two timeframes (can be Time, Date, or DateTime objects or integers) and displays it in a nice, humanized format. To be correct, the leap years between those two timeframes should be considered. It uses count and a range to get the number of leap years.
