Description

Right now, caches only know how to download and use one single consensus flavor. We need them to be able to fetch, parse, store, and serve every flavor. Right now, that means "normal" and "microdesc".

Storing and serving are already implemented (I believe) since authorities do them. Parsing and fetching remain are partially implemented in my "microdesc_dl" branch.

See proposals 158 and 162 for more information.

A fun note: caches use consensuses for up to three things:

  • Serving them to non-caches
  • Learning which descriptors (and microdescriptors) to download.
  • Using them to learn which servers exist, so they can build circuits themselves.

The first one can be done without parsing the consensus; just check its signature. The second means that all caches need both consensuses, parsed.

This is currently done in my microdesc_dl_v2 branch.
