We’ve upgraded lemmy.world to 0.18.1-rc.1 and rolled back that upgrade because of issues.

(If you had posted anything in those 10 minutes between upgrade and rollback, that post is gone. Sorry!)

The main issue we saw is that users can’t login anymore. Existing sessions still worked, but new logins failed (from macos, ios and android. From linux and windows it worked)

Also new account creation didn’t work.

I’ll create an issue for the devs and retry once it’s fixed.

Edit Contacted the devs, they tell me to try again with lemmy-ui at version 0.18.0. Will try again, brace for some downtime!

Edit 2 So we upgraded again, and it seemed to work nicely! But then it slowed down so much it was unuseable. There were many locks in the database. People reported many JSON errors. Sorry, we won’t be on 0.18.1 any time soon I’m afraid…

      Because of a few things, really anoying bugs and the Jerboa app not working properly with older versions

      I suspect there will be a large influx of new users in two days, and that having Jerboa not working on .world might cause a few issues

      Reasons I can think of:

      1. The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.

      2. Sorting is broken pre 0.18, new posts keeps flowing in.

      3. Performance improvement by removing web socket from lemmy. (which fixes 2, which is why 1. happens)

          The latest version only supports 0.18 because the backend works differently. Older versions of Jerboa support older backends of lemmy.

          Likely because Jebora is written as a side project of the devs of lemmy so it’s always going to be cutting edge

            I understand that. I’m not complaining about the quality. I’m just confused from a technical perspective why it doesn’t support rollback or older server versions in the event of…this.

              Fixing the issues with posts appearing and scrolling the page the backend needed some pretty drastic rewrites. I’m not super familiar, but from what I’ve seen of the code, it would be a decent amount more work to support both versions.

              Would it have been worth it? Yes, but it wasn’t anticipated that devs would stay on 0.0.17 for more than a day or two. With the time it takes for app stores to update, servers would have been updated before lemmy 0.0.45 was updated for the vast majority of users. At most, it would be a day or two instead of a week or two.

        The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.

        Even that won’t work, because Jerboa initially tries to connect to lemmy.ml which is running 0.18, which older versions of Jerboa aren’t compatible with. The app just crashes instantly without giving you the opportunity to log in to your instance.

        Jerboa works fine with lemmy world, it just gives a warning and crashes on occasion. Not an issue to use it though.

      For example the frontpage is no longer being constantly filled with random posts when you set the filter to “active” or “top day”.

      Federation is completely borked with .18 servers. Its very difficult for us to interact with https://lemmy.ca in any way: subscribing, upvoting, comments, posting… its all bugged.

      Its maybe not that big a deal because Lemmy.world “has the most users”, so in some regards its https://lemmy.ca’s loss but… we need to restore reliable federation… especially before the July 1st rush IMO.

      The .17 to .18 upgrade is basically a soft-defederation event, because of whatever this bug is between the two versions.

        Ah that explains it. Someone posted a cool photo to my community from lemmy.ca but didn’t interact further. Looks like my comment didn’t even show up on their end.

        Anyway, thanks to everyone working on the issue. I know these things aren’t easy.

          I’m subscribed to lemmy.ca and programming.dev, both of which are .18 now. Feels kinda bad losing access to those communities while this issue is getting worked out…

      Just curious, why are we updating now instead of waiting for the proper 0.18.1 release?

      A Release Candidate is supposed to be past beta testing already and in a state of no major bugs.

      Cause if you are on the homepage for a little bit new post start pushing the old post down and it keeps doing it. something about websockets that 18 fixes it. im assuming the admins want to get it out now so people can stop complaining about it. i get it though just wait for the 18 instead of the rc-1 but users are impatient and can’t wait for sh*t!
