Should bridge lines in the state file use unlisted_since?
I have a bridge in my recent Tor (post prop#271), and my state file now says:
Guard in=bridges rsa_id=C7BE8154678E7537CCAC60B097D51A8A7EF8BCDF bridge_addr=18.104.22.168:94 sampled_on=2017-05-04T10:39:09 sampled_by=0.3.1.0-alpha-dev unlisted_since=2017-05-11T05:47:41 listed=0 confirmed_on=2017-05-02T01:15:03 confirmed_idx=0 pb_use_attempts=1.000000 pb_use_successes=1.000000 pb_circ_attempts=11.000000 pb_circ_successes=11.000000 pb_successful_circuits_closed=11.000000
The unlisted_since and listed=0 are not surprising, since bridges will never be listed, right? Does that make my Tor do anything I shouldn't want it to do, like throw out the bridge line sooner than I'd want? I think no, because hey if it's in torrc it'll go back in, but maybe throwing out the path bias info early was not what we expect?
