commit 2e600019ea32277525c46809244491970869b084 Author: David Goulet dgoulet@torproject.org Date: Fri Jan 22 10:35:32 2021 -0500
relay: Don't trigger an address discovery without an ORPort
We would before do an address discovery and then a lookup in the cache if not found which is now simplified by calling relay_find_addr_to_publish() directly which does all those combined.
Furthermore, by doing so, we won't trigger an address discovery every minute if we have no ORPort configured for the family.
Fixes #40254
