Hi all,
Fallback directory mirrors help clients reach the Tor network.
We need to rebuild the list every so often when their details change. (We have an automated check for 25% failure, and it just triggered.)
Does anyone want to help me do this? It would be nice to get it done this month - but it's not urgent.
Here's what needs to be done in detail:
0. Ask operators to opt-in stable relays as fallback directory mirrors If they are on the whitelist already, they don't need to do anything. Ticket: https://trac.torproject.org/projects/tor/ticket/22527 File: https://gitweb.torproject.org/tor.git/tree/scripts/maint/fallback.whitelist
1. Update the fallback whitelist with new and changed relay details Tickets: https://trac.torproject.org/projects/tor/ticket/22321 https://trac.torproject.org/projects/tor/ticket/22527 File: tor/scripts/maint/fallback.whitelist
2. Update updateFallbackDirs.py to have a CONSENSUS_EXPIRY_TOLERANCE of 0. Ticket: https://trac.torproject.org/projects/tor/ticket/20942 File: tor/scripts/maint/updateFallbackDirs.py
3. Run updateFallbackDirs.py with the new whitelist and CONSENSUS_EXPIRY_TOLERANCE. You'll need a decent network connection for this. Please attach the script logs to the trac ticket. Command: tor/scripts/maint/updateFallbackDirs.py > src/or/fallback_dirs.inc
4. Write a changes file Ticket: https://trac.torproject.org/projects/tor/ticket/22271 Draft:
o Minor features (fallback directory list): - Replace the 151 fallbacks originally introduced in Tor 0.3.1.3-alpha in May 2017 (of which ~111 were still functional) with a list of NNN fallbacks (NNN new, NNN unchanged, NNN removed) generated in December 2017. Resolves ticket 22271.
There are some commands that count fallback changes here: https://trac.torproject.org/projects/tor/wiki/doc/UpdatingFallbackDirectoryM...
5. Announce the new list on tor-relays@
6. Tell the relay search maintainer that the list has changed
Next Time:
I'd like to make the process quicker and easier next time. But I don't want to make any big changes to it at the moment. Let's do that when we have time to try different things.
