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..

Not that we'd get them during maintenance but this is a good reason to have some kind of DM system.

So how does this work..is there a beta server to try it on? Or it worked in resting and it only broke with the full amount of users?

After the update I can no longer log in or interact with Jerboa. Hopefully y'all resolve this soon, as I am really digging Jerboa, but thanks for letting us know what's going on, and keeping up the good work.

There's a major breaking change in the 0.18 update (moving away from Websockets for posts and comments), that means that older Jerboa builds no longer work with instances on, or past, that version, and newer Jerboa builds won't work with servers older than 0.18.

[–] Dran_Arcana@lemmy.world 0 points 2 years ago (2 children)

Version fracturing is probably going to be a fact of life on a decentralized platform like lemmy, a "good" app should probably handle cases for the latest few revisions instead of just the latest.

[–] T156@lemmy.world 0 points 2 years ago (3 children)

It normally would, it's just that 0.18 is a breaking change, incorporating a major rewrite of how posts and comments work on Lemmy.

FYI, my UI is currently a bit buggy after the second rollback.

create post UI:

expanding the menu messes up the header:

Is there any place that people can assist in trying to figure out issues?

[–] ruud@lemmy.world 0 points 2 years ago (1 children)

Well you can either help the devs via their Github, or if you wanna help sysadmin the server I can send you a link to our Discord.

[–] devopspalmer@lemmy.world -1 points 2 years ago

Thanks for the response, Going to look into the github/code side but I may reach out in the near future to help where needed. πŸ˜€

[–] erik1984@lemmy.world 0 points 2 years ago (1 children)

Thanks for the update! (I mean the communication regarding the update) 0.18 moved away web sockets right? Maybe that leads to different DB access patterns causing locks on such a big instance as lemmy.world.

Good luck! May the software gods bless you with a functioning website with minimal bugs!

Im already in lemmy 0.19.0

this comment is from the future

[–] necrxfagivs@mastodon.world 0 points 2 years ago (1 children)

@ruud Lemmy is empty for me right now. I was able to browse in 0.18.1, but it was really slow and tons of JSON problems.

[–] necrxfagivs@mastodon.world 0 points 2 years ago (1 children)

@ruud I took the screenshot now (UI: 0.18.0
BE: 0.17.4)

I’ve found from hopping around some other instances that have upgraded to 0.18 that it is still pretty buggy. It does seem to be giving more information about the errors, instead of just failing like in 0.17, but spend any time browsing on those instances and you’re bound to be inundated with JSON and query errors. It also seems to get worse the longer you browse.

The UI changes are nice, and I do appreciate not having my feed auto-updating constantly, but I think you’d be making the right choice to hold off on upgrading until they can iron 0.18.1 out all the way. I’m not super knowledgeable about TS and Rust, but as a user it seems that switching from WebSocket created/shined a light on Lemmy’s issues with caching in general.

Oh. Good luck with the next try!

[–] Tenthrow@lemmy.world 0 points 2 years ago (1 children)

So are we stable now? I lost some posts and comments this morning.

[–] ruud@lemmy.world 0 points 2 years ago (1 children)

Yeah we won't try again until a stable version is released with the performance issues fixed..

Running one of the largest and most vibrant Lemmy instances certainly makes this deployment a great test case for the devs and the system overall. @ruud@lemmy.world this community really appreciates you!

[–] snargledorf@lemmy.world 0 points 2 years ago* (last edited 2 years ago) (1 children)

~~RC2~~ RC4 was just released, here's hoping it solves the issues you were experiencing with performance of RC1!

[–] rcmaehl@lemmy.world 0 points 2 years ago (2 children)

I thought RC3 was just released?
