  o Minor features (authorities)
    - Take altered router IP addresses and ORPorts into account when
      determining router stability.  Previously, if a router changed
      its IP or ORPort, the authorities would not treat it as having
      any downtime for the purposes of stability calculation, whereas
      clients would experience downtime since the change could take a
      while to propagate to them.  Resolves issue 1035.
  o Minor bugfixes (authorities)
    - Try to be more robust to hops back in time when calculating
      router stability.  Previously, if a run of uptime or downtime
      appeared to be negative, the calculation could give incorrect
      results.  Bugfix on 0.2.0.6-alpha.
Treat routers whose IPs have changed as having been down for MTBF/routerinfo calculation purposes. 2010-11-22 18:30:33 +01:00			`o Minor features (authorities)`
Routers count as down when they change ORPort, too rransom noticed that a change of ORPort is just as bad as a change of IP address from a client's perspective, because both mean that the relay is not available to them while the new information hasn't propagated. Change the bug1035 fix accordingly. Also make sure we don't log a bridge's IP address (which might happen when we are the bridge authority). 2011-02-07 16:31:20 +01:00			`- Take altered router IP addresses and ORPorts into account when`
