obfs4_bridgeline.txt file should contain complete bridge line

When setting up an obfs4 bridge, the user has to perform extra steps to fill in the missing values to construct the full bridge line from /var/lib/tor/pt_state/obfs4_bridgeline.txt.

Specifically in: Bridge obfs4 <IP ADDRESS>:<PORT> <FINGERPRINT> cert=<CERTIFICATE> iat-mode=0 only cert is populated automatically

Thanks! I agree this is an important thing to do for usability for bridge operators.

I would guess the hard part here might be that obfs4 knows some of the info, and Tor knows others of it, and no side easily knows both.

So it seems like we should have one side send the other side what it needs, so some side knows everything.

no side easily knows both.

The tor daemon, knows everything because it's what generates and uploads the descriptor.

I'm tempted to call this a Tor ticket then, and Tor should write the whole bridge line to a log entry, or to a state file, or some other smart place?

(I imagine some people will be nervous about the idea of putting it in the log file, "because what if the operator accidentally reveals it to somebody", but I think usability trumps risk here.)

I'm tempted to call this a Tor ticket then

That's what I would propose. Instead of passing extra information (that's not needed for anything other than this ticket) to each PT provider, it makes more sense to me to do it at a place where all of the information already exists.

Maybe follow the obfs4 model and write all of the bridge lines to $DATADIR/pt_state/bridgelines.txt perhaps.
