[tor/maint-0.2.2] Fix bug when parsing bwhist with unexpected Interval
by nickm＠torproject.org 25 Feb '11

25 Feb '11

commit 7e1502c0d1aa0875fba0b26ddcf021bdfa5e11a0 Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jan 10 13:06:50 2011 -0500 Fix bug when parsing bwhist with unexpected Interval Previously, our state parsing code would fail to parse a bwhist correctly if the Interval was anything other than the default hardcoded 15 minutes. This change makes the parsing less incorrect, though the resulting history array might get strange values in it if the intervals don't match the one we're using. (That is, if stuff was generated in 15 minute intervals, and we read it into an array that expects 30 minute intervals, we're fine, since values can be combined pairwise. But if we generate data at 30 minute intervals and read it into 15 minute intervals, alternating buckets will be empty.)
