[tor-dev] New Authority File (was: Re: New Fallback Directory File Format)

[teor]

Hi,

We've merged a new list of fallbacks in the version 2.0.0 format.

But we also want to keep a separate list of authorities, rather than hiding
them in the middle of config.c:

https://trac.torproject.org/projects/tor/ticket/24818

So we are changing the current authority and fallback list formats,
to make them consistent with each other. (Sorry about doing the two changes
separately, we had to do fallbacks for the 0.3.2.9 release deadline.)

Here's what will change in version 3.0.0:

https://github.com/teor2345/torspec/commits/dir-list

Hopefully, you can use the same parser for both file formats.

The fallback list spec version 2.0.0 has been merged, it's now at:

I'm glad this worked out!
Thanks for doing this update.
