From 1b5806b74475213ae45b483d08a29daa40988f84 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Sat, 2 Sep 2017 14:01:23 +0200 Subject: [PATCH] Define missing JSON-LD properties (#4767) Using _: property names is discouraged, as in the future, canonicalization may throw an error when encountering that instead of discarding it silently like it does now. We are defining some ActivityStreams properties which we expect to land in ActivityStreams eventually, to ensure that future versions of Mastodon will remain compatible with this even once that happens. Those would be `locked`, `sensitive` and `Hashtag` We are defining a custom context inline for some properties which we do not expect to land in any other context. `atomUri`, `inReplyToAtomUri` and `conversation` are part of the custom defined OStatus context. --- app/lib/activitypub/activity/create.rb | 6 +++--- app/lib/activitypub/activity/delete.rb | 2 +- app/lib/activitypub/adapter.rb | 20 ++++++++++++++++++- .../activitypub/actor_serializer.rb | 4 +--- .../activitypub/delete_serializer.rb | 3 +-- .../activitypub/note_serializer.rb | 17 ++++++++++++---- .../fetch_remote_status_service.rb | 4 ++-- .../activitypub/process_account_service.rb | 2 +- 8 files changed, 41 insertions(+), 17 deletions(-) diff --git a/app/lib/activitypub/activity/create.rb b/app/lib/activitypub/activity/create.rb index a6f1e60d..081e8057 100644 --- a/app/lib/activitypub/activity/create.rb +++ b/app/lib/activitypub/activity/create.rb @@ -26,7 +26,7 @@ class ActivityPub::Activity::Create < ActivityPub::Activity def find_existing_status status = status_from_uri(object_uri) - status ||= Status.find_by(uri: @object['_:atomUri']) if @object['_:atomUri'].present?
