From 8cf7006d4efbcfdd4a4ab688db1bcc73a2915a47 Mon Sep 17 00:00:00 2001 From: Claire Date: Wed, 21 Sep 2022 22:45:57 +0200 Subject: Refactor ActivityPub handling to prepare for non-Account actors (#19212) * Move ActivityPub::FetchRemoteAccountService to ActivityPub::FetchRemoteActorService ActivityPub::FetchRemoteAccountService is kept as a wrapper for when the actor is specifically required to be an Account * Refactor SignatureVerification to allow non-Account actors * fixup! Move ActivityPub::FetchRemoteAccountService to ActivityPub::FetchRemoteActorService * Refactor ActivityPub::FetchRemoteKeyService to potentially return non-Account actors * Refactor inbound ActivityPub payload processing to accept non-Account actors * Refactor inbound ActivityPub processing to accept activities relayed through non-Account * Refactor how Account key URIs are built * Refactor Request and drop unused key_id_format parameter * Rename ActivityPub::Dereferencer `signature_account` to `signature_actor` --- .../activitypub/fetch_remote_actor_service_spec.rb | 180
