    Change to the link format from now on, to also support mbin and other fediverse apps that may come along.

    I didn’t do it like this before, because earlier versions of Jerboa didn’t understand this link type, and I don’t like that it repeats information - the name and the description are often the same, but not always, and the name can be hard to read, so the description needs to be there, but it’s often redundant. I can’t combine the description and link like [Hello Internet](!hellointernet@@feddit.uk) because lemmy will interpret that as link to a post for some reason.

    I tested in the front-ends and mobile apps I have available, and they all work.

    I’ve been resistant to changing it to this, and when mobile app users have said that they’re app didn’t support ‘/c/’ links, I’ve been “well, fix your app then”, but it turns out that all you have to do is say the magic words ‘Fediverse Interoperability!’ to me and you can win the argument.

    I’m not sure they are supported.

    Firstly, I should clarify that lemmon.website is mine, and I’m the only user that’s ever been on there.

    When I was running Mastodon, I noticed that, after I’d unsubscribed to the lemmy.ml communities, there was still entries for incoming activities in the systemd journal. Before I stopped running Mastodon, I unsubscribed from all lemmy.world communities. After I started up a new, basic server using Rust’s hyper library, I saw that all activity from both lemmy.ml and lemmy.world was still POSTing to /inbox

    I think what happens is that, when a Mastodon user unsubscribes, the software longer views the community’s public key as valid, so it doesn’t show the posts, etc, but you haven’t ‘really’ unsubscribed because lemmy has errored. Here’s how I’ve tested this.

    1. Start a brand new lemmy instance, on a linux VM in Windows, using ngrok to tunnel though from a ephemeral URL. So, right now, there’s lemmy service you can see running using:
      curl --header 'accept: application/activity+json' https://f2d0-77-100-144-83.ngrok-free.app/api/v3/site

    2. Log in to a Mastodon server that’s designed to let users experiement with ActivityPub (https://activitypub.academy/), to subscribe and unsubscribe to a new-created test community. It looks from there like:

    But in lemmy, it shows the same ‘WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: Unknown’ that I quoted in my first post

    I don’t know what that error means. But I can see that lemmy still thinks it’s federating with 1/1 instances, and if I create a post on the test community, I can see it do:

    INFO send:send:send_lemmy_activity: lemmy_apub::activities: Saving outgoing activity to queue https://f2d0-77-100-144-83.ngrok-free.app/activities/announce/create/ea41951a-6430-4e53-a5c4-afd644bf0824

    1. To investigate the error, I tried sending JSONs in the same format that Mastodon uses, but utilising a command-line script. The Follow works, but the Undo-Follow doesn’t. The header returned shows the same error as journalctl does: 400 Bad Request "{\"error\":\"unknown\",\"message\":\"\"}"

    I then recrafted the JSONs to be more like lemmy, changing the ‘id’ of Undo to have ‘activities/undo/UUID-string’, and that works. No entries in journalctl, and a 200 OK Response header.

    1. From lemmon.website, I can use the script to Follow and Unfollow communities on lemmy.ml

    EDIT: I’ve had some success with this. Using the private key of the old Mastodon user I’m no longer getting stuff from ‘memes’ now, I think. (still stuff from ‘asklemmy’ though).

    I’ll keep tinkering with this. Maybe during testing I followed asklemmy from another user. In the meantime though, it’d help enormously if any Follows from anyone at lemmon.website could be undone at your end (like I say: it’s all me)

    (There is still the JSON problem though. It suggests that any ‘Undo-Follows’ you get from mastodon accounts aren’t being processed properly, so you’re maybe wasting subsequent federation activity. I realize that’s more a lemmy software issue than lemmy.ml issue, but it’s my understanding that you’re the same people!)
