Hi all,
Some time in the next few weeks, the Tor fallback directory mirror file format will change. This affects stem and Relay Search, which parse this file.
Change Description
Here is a list of changes to the file format: * the "weight" line has been removed, and replaced with a Tor config default (#24679, #24681) * the comma that separates fallback C strings is now on its own line * a "nickname" comment has been added (#24600) * an optional "extrainfo" comment has been added (#22759)
The added fields will be populated with placeholders until the list is rebuilt (#22271). This will hopefully happen some time in the next few weeks.
Requesting More Extra Info Caches
There are only a few fallbacks that cache extra-info documents. I checked 67, and only 4 cached extra-info documents.
atagar, do you want me to ask some fallback operators to set DownloadExtraInfo 1?
What number or proportion would you like?
(We allow approximately 25% of fallbacks to go down before we start to rebuild the list. In the worst case, this can mean that ~40% are down at some point.)
Example Entries
A sample entry in the new format, using actual relay info:
"5.9.110.236:9030 orport=9001 id=0756B7CD4DFC8182BE23143FAC0642F515182CEB" " ipv6=[2a01:4f8:162:51e2::2]:9001" /* nickname=rueckgrat */ /* extrainfo=1 */ ,
The current fallback file in the new format, with placeholders: https://github.com/teor2345/tor/blob/ticket22759_tree/src/or/fallback_dirs.i...
A small sample fallback file in the new format, with actual relay info: https://trac.torproject.org/projects/tor/attachment/ticket/22759/fallback_di...
Please let me know if you would like any changes to the format.
