activity pub enhancements

[maybeanerd]

TODOs to make AP support better

• [x] add nodeinfo (which should point to the instance endpoint then?) https://github.com/jhass/nodeinfo/blob/main/PROTOCOL.md
• [x] look into HTTP signing! This is necessary to federate with most other platforms, like mastodon
• [x] fix actor (and general) retrieval by changing/adding content type https://www.w3.org/TR/activitypub/#retrieving-objects
• [x] support activitypub content-type headers in fastify: maybe use https://fastify.dev/docs/latest/Reference/ContentTypeParser/#content-type-parser
• [x] send content-type headers in signed request util when passing a body
• [x] make outbox GET an ordered collection https://www.w3.org/TR/activitystreams-vocabulary/#dfn-orderedcollection
• [x] make inbox POST allow a single object. Maybe even force that? Might make delivery "easier" https://www.w3.org/TR/activitypub/#delivery
• [x] get verify.funfedi to clear (getting stuff with signatures). Signing is still weird, read into it here: https://funfedi.dev/testing_tools/http_signatures/ . Most likely sending the digest on non-post requests is the issue
• [x] remove versioning from ActivityPub controller. They won't be able to be changed, as they are used as IDs
• [x] test signing acceptance with services like mastodon
• [x] send back "Accept" activities for follows, to allow other platforms to follow game servers. Game servers themselves do NOT wait for follow accepts, as they will only form a treaty on mutual follow anyways -> doing this, but it doesnt work. Might be that mastodon expects the entire activity object to be inline instead of just referencing the objectId
• [x] #741
• [ ] validate signing from others (game as well as other AP instances) - this is necessary for the last verify.funfedi test https://docs.joinmastodon.org/spec/security/#http-sign
• [ ] on outbox posting, target servers better (e.g. follow/unfollow only to the respective servers, as well as likes) Only things that belong to own trades (create, delete) should be shared to all
• [ ] when starting to follow/a treaty, query the outbox to backfill previous activities. Prob necessary to add pagination and date markers for that
• [ ] adjust outbox: only include create activities of notes that have not also been deleted already

Maybe also interesting (e.g. for nodeinfo)
