commit 56f713b8a477b4203f3bfd8f3ad0952706dc9599 Author: David Goulet <dgoulet@torproject.org> Date: Thu Oct 18 11:44:26 2018 -0400 hs-v3: Always generate the descriptor cookie It won't be used if there are no authorized client configured. We do that so we can easily support the addition of a client with a HUP signal which allow us to avoid more complex code path to generate that cookie if we have at least one client auth and we had none before.
