Re: [tor-dev] onionoo: bug in family set detection?
Hello,
DirAuth's can cache multiple versions of the descriptor
and serve what appears to be the newest in a given consensus interval.
This coupled with routers publishing descriptors at least every 18
hours, but potentially sooner. What you describe doesn't appear to
be a bug in Onionoo because a consensus exists for which the family is
declared as you describe in the last known good descriptor.
At the moment you describe Atlas doesn't show:
[1] last published 2015-06-02 17:44:27 (and [2] may still have entered hibernate)
[2] last published 2015-06-02 09:40:45 (and [1] may not be running, or have a last known good descriptor at DirAuths)
This doesn't take into account the possibility
of a router hibernating (info not always available) at times between
consensus taken or valid. A router can be running but unavailable due to
accounting. This looks like a result of cached descriptors or router
accounting. The data provided to Onionoo from metrics-lib appears
accurate as far as network status. At least that's how it looks from a preliminary glance at the data and spec--although please do your own verification.
