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

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

      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 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.

          Yes, if you are already logged in. If you are not logged in, or get logged out you will not be able to log back in until the server version is above 0.18

          As a new user I tried logging in on Jerboa and it says the server must be on 0.18 and refuses the login.

          Well you’re a lucky one. Jerboa has been unusable for me and other folks post v0.34 since the first rc release of 0.18. I finally managed to downgrade to 0.34 and login after lots of black magic. It used to crash instantly, even on 0.34.

          That being said, good luck to lemmy.world admins and thanks a lot for the open comms !

          For me at least, I’m unable to change the community scope or sorting method. The only thing I can use Jerboa for is “local” and sorted by “active”. It isn’t totally unusable, but I would much rather be able to switch to subscribed and hot.

              Unfortunately that didn’t work for me. Thanks for the idea, though. I’m sure it will work for some. I suspect that if I wiped the app and set everything back up it might work, but that’s more than I’m willing to do at the moment and I can live with the inconvenience for now.

          With the last couple updates jerboa has got to a point that I probably won’t even move to sync when it comes. I’m pretty happy with it. But if Lemmy Is Fun ever happens, I’m out.

            I’m of a similar mind: I’m happy with Jerboa, yet also looking forward to Slide.

          “crashes on occasion”

          Unfortunately, the occasion seems to be at least once every five minutes for me. thisisfine.jpg This is not fine and definitely a major issue. Especially as we get closer to July 1. After this news from lemmy.world, I will have to switch, probably to Connect, until Sync arrives.

          I don’t know but I installed and older version of Jerboa from F-Droid store. I couldn’t login from the most recent version of Jerboa because of this so it was pretty much useless for me. Working fine so far.

          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.

            • Darorad@lemmy.world

              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.

      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!

    As any engineer who does ops can tell you - you did the right thing - the solution is always to roll back, never force a roll forward, ever.

    We should totally do pre and post update parties though. Even if the update fails we can have an excuse for drinks and a fun thread.

      Yeah they’ve been hard at work all month. But it’s also okay if things aren’t ready in time. Most of the people who matter are already here.

      Maybe we will blow up soon, maybe later, but the quality of content here is sufficient to drive growth regardless of whether or not we get the prophesized huge migrations from reddit

        Agreed. I’m here to stay with the content from the last couple weeks. 3 day poop embargoes alone is worth it. And recognizing users because the community is still small enough is SO different from they who shall not be named.

    @ruud@lemmy.world just wondering if you have considered setting up a second, beta, instance of lemmy.world open to the public?

    With all the performance issues with 0.18.1, it’s highlighted that there needs to be a way to stress test these updates before applying them to the main instance.

    • Ruud@lemmy.worldOPM

      Yes, considering that. But we’ll need people to use that when we will do testing…

          One more. You find a stable way to notify anout upgrades and get a test sheet to run through and we can generate posts and activity to help test with.

        I’m not familiar with what the server architecture looks like, but is there a possibility of using a load balancer in front of the instance’s server and swapping a “beta” server into the load balancer when you need to do testing? You could basically migrate your traffic with zero downtime, assuming Lemmy’s architecture allows for it.

          Well that doesn’t differ much from what I do. I just copy the files to a second directory and test with that. Easy rollback. Downside is, that all data is lost between upgrade and rollback, which will be the same in the scenario you suggest.
