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..

Thank you for the transparancy!

[–] GatoB@lemmy.world 9 points 1 year ago

I love post like this, another reason of why this instance is so good

[–] morelikepinniped@lemmy.world 38 points 1 year ago

Thanks for all your hard work @ruud@lemmy.world. It's not easy!

[–] ulu_mulu@lemmy.world 18 points 1 year ago (1 children)

is that users can’t login anymore

Ouch, that's bad :(

Thank you for your work, as always :)

I mean that’s a Tuesday on Reddit lmao.

[–] OsrsNeedsF2P@lemmy.ml 18 points 1 year ago (4 children)

Both Dessalines and Nutomic have been working their butts off to get 0.18.x ready for the Reddit API changes. Huge hopes they can pull through!

UI: 0.18.0 BE: 0.18.1-rc.1 πŸ‘

seems to be working for me, I was already logged on

[–] rrobin@lemmy.world 14 points 1 year ago (1 children)

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.

Thanks for all your work!

Perhaps it would be beneficial to have a temporary test instance like dev.lemmy.world or something where you dedicate a limited amount of processing power to. That way you could test the update live but not affect the main instance.

I have no idea about the specifics so that may not be doable.

[–] antik@lemmy.world 18 points 1 year ago (1 children)

We have one! This was tested on a test instance before

[–] runswithjedi@lemmy.world 9 points 1 year ago

Cool, great minds think alike 😁

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

[–] ruud@lemmy.world 13 points 1 year ago

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

[–] axzxc1236@lemmy.world 11 points 1 year ago* (last edited 1 year ago) (30 children)

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)

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

[–] runswithjedi@lemmy.world 7 points 1 year ago (1 children)

I read the post as needing to update to 0.18.0 before updating to 0.18.1.

[–] ndr@lemmy.world 5 points 1 year ago (1 children)

UI at 0.18.0 and backend at .1rc1

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

[–] dragontamer@lemmy.world 5 points 1 year ago* (last edited 1 year ago) (2 children)

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.

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

[–] Nintendo@lemmy.world 7 points 1 year ago

appreciate the transparency. how are things looking in the back in lemmy.world (server wise)? will we get to a point where it wont require complete rollbacks on the state when a botched update gets rolled out?

[–] slimerancher@lemmy.world 7 points 1 year ago

Oh. Good luck with the next try!

[–] necropola@lemmy.world 6 points 1 year ago* (last edited 1 year ago) (6 children)

Everything (UI) is extremely slow now. Not an improvement at all. Also I'm frequently getting error messages like this now:

I am glad I didn't write my last post during the upgrade process.

Maybe next time, give a warning, or maintenance notice.

Thanks for trying though.

@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.

PSA: If you've been using lemmy.world during the upgrades and rollbacks your browser might've cashed some stuff that quickly got out of date. If you have problems (especially JSON errors), try doing a hard refresh (usually Ctrl + F5) on the site. It might log you out.

[–] itadakimasu@lemmy.world 5 points 1 year ago

Thanks for the hard work /u/ruud, we'll get there

[–] naneek@lemmy.world 5 points 1 year ago* (last edited 1 year ago) (1 children)

Thanks for the transparency. Maybe it’s a good idea to have a test instance and some test cases/validation done there before updating the main instance. This is a regular process in any software/tech company/stack.

Testing should never be done directly on the prod instance.

[–] 65gmexl3@lemmy.world 5 points 1 year ago (1 children)

i think they tested it which worked fine, but it is totally different when there are users online

[–] antik@lemmy.world 7 points 1 year ago

Correct there was a test instance and that worked fine but once the live instance was upgraded everything became very slow. Can't really emulate that kind of load

[–] Asudox@lemmy.world 4 points 1 year ago (1 children)

I am glad y'all rolled back. I had just enabled 2FA and could not login to my account. Rolling back removed 2FA so I was able to log back in. Thanks.

Seems 0.18 is up... and...

OH NO ! The interface changed ! Bring it back ! Bring it back... /s

Just kidding... It's looking good, so it's time to explore a little and find all the new stuff.

Nice work @Rudd, thanks for all the hard work.

[–] Spitz@lemmy.world 4 points 1 year ago (4 children)

Jerboa crashes constantly for me now, doesn't even let me view anything. JSYK!

My current session works now with 0.18.0 + 0.18.1.rc1

[–] Buffalox@lemmy.world 4 points 1 year ago

Linux/Firefox After upgrade many things didn't work, but they continued not to work after rollback.

Turns out I needed to clear the cache, then everything worked fine again.

[–] Shadywack@lemmy.world 4 points 1 year ago

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!

[–] DRx@lemmy.world 4 points 1 year ago

Damn, Im glad you tried, and thanks for the update! I just really want the front page fixed without changing to page 0 lol. That and the 3/6/12 hour filter option.

Keep us updated. Im bouncing back and forth between LW, KBIN, and .ml for now though

any recommendations on other instances I should try outside the lemmy-verse and kbin-verse?

[–] Spitz@lemmy.world 4 points 1 year ago (12 children)

Jerboa is almost unusable for me at the moment. A lot of crashes, pages not loading, messages not sending etc. But I know that's inevitable at times. Restarting my phone seemed to make it worse. But I know you guys are on it! πŸ‘
