commit 105b94b75b51376128037cab05b930c4e4c15497 Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jan 10 14:11:22 2011 -0500 Add Maxima lists to bandwidth state. Right now, Tor routers don't save the maxima values from the bw_history_t between sessions. That's no good, since we use those values to determine bandwidth. This code adds a new BWHist.*Maximum set of values to the state file.
