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..

@[email protected] 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.

[โ€“] neblem 2 points 1 year ago (1 children)

Is there a way to have two instances writing to the same db? That'd help a lot in this situation so the test instance can still be accessing the same data as the stable instance. Otherwise we'll never have enough load to fully stress test and be in the same situation as the three existing Lemmy test instances.

Seeing that with these updates often come with changes to the database as well, that could be very difficult if not impossible.
