Looks like it works.

Edit still see some performance issues. Needs more troubleshooting

Update: Registrations re-opened We encountered a bug where people could not log in, see https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264 . As a workaround we opened registrations.

Thanks

First of all, I would like to thank the Lemmy.world team and the 2 admins of other servers @[email protected] and @[email protected] for their help! We did some thorough troubleshooting to get this working!

The upgrade

The upgrade itself isn't too hard. Create a backup, and then change the image names in the docker-compose.yml and restart.

But, like the first 2 tries, after a few minutes the site started getting slow until it stopped responding. Then the troubleshooting started.

The solutions

What I had noticed previously, is that the lemmy container could reach around 1500% CPU usage, above that the site got slow. Which is weird, because the server has 64 threads, so 6400% should be the max. So we tried what @[email protected] had suggested before: we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.

Et voilร . That seems to work.

Also, as suggested by him, we start the lemmy containers with the scheduler disabled, and have 1 extra lemmy running with the scheduler enabled, unused for other stuff.

There will be room for improvement, and probably new bugs, but we're very happy lemmy.world is now at 0.18.1-rc. This fixes a lot of bugs.

Well, I hope I'm not the only one but I cannot log in. It's been 4 hours already. Something went wrong. I'm on Firefox mobile.

--> few hours later everything is back to normal

[โ€“] [email protected] 9 points 1 year ago

I am having the same issue. Iโ€™m in with Mlem, but I can not log in on the site. I even tried it with content blockers off in case there was a captcha or something being blocked.

[โ€“] [email protected] 1 points 1 year ago

yes, it does, thanks!

[โ€“] [email protected] 7 points 1 year ago

I'm having the same issue too, including after clearing cache and trying incognito etc.

[โ€“] [email protected] 7 points 1 year ago* (last edited 1 year ago)

You can send a reset password, and the link to reset the password will log you in as your password is updated.

However, the login button remains broken, even after password reset. Still, this provides us a 2nd way in if your browser cache gets cleared.


The XHR for the button reports back a 404 error, suggesting that login page just stopped existing after the update. I'm assuming that it will be an easy hotfix, just gotta fix the link to the POST form to point at wherever the login page went.

[โ€“] [email protected] 4 points 1 year ago

This needs to be higher. It happens on all browsers and on jebora as far as I can tell.

[โ€“] [email protected] 3 points 1 year ago

Get the same but also in addition it happens in Liftoff.

[โ€“] [email protected] 3 points 1 year ago (1 children)

It drove me nuts too and I hope admins remove the "clear your browser cache" advice from the homepage, because that will simply lock you out of your account if the login form is broken.

Right now the login form seems to work again though? Can you try again?

[โ€“] [email protected] 2 points 1 year ago

yes, it's working again, at least for me

[โ€“] [email protected] 2 points 1 year ago

It's weird that people seem to be having very different experiences with this. Liftoff says it's logged in for me on my 'world' account, but posting/checking account details doesn't work - Jerboa won't login, resetting the password works once on the web, but subsequent logins don't work.

[โ€“] [email protected] 1 points 1 year ago (4 children)

Clearing the browser cache should fix the issue :)

[โ€“] [email protected] 9 points 1 year ago* (last edited 1 year ago) (3 children)

Didn't work for me on Jerboa. I cleared the app data, but I'm I still not able to login.

Edit: I've tried again just now and I could login on Jerboa.

[โ€“] [email protected] 4 points 1 year ago

I have this issue on my own instance. Neither Jerboa or Liftoff can log in to my main account (no errors or anything), but for some reason my admin account (one that pretty much sees no activity) works just fine. Thunder seems to be the only app aside of the web ui that works. Maybe an 0.18 issue?

[โ€“] [email protected] 4 points 1 year ago

I can't get into my sh.it acct on Jerboa either.

[โ€“] [email protected] 1 points 1 year ago

Mh.. some people said they tried a password reset
But I can't confirm if this is working

[โ€“] [email protected] 7 points 1 year ago

Unfortunately it does not, everyone having the same issue try to create account on different instance and comment on this bug in here.

[โ€“] [email protected] 7 points 1 year ago

I've tried multiple times. It doesn't.

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

it has nothing to do with cookies (and my advice is to NOT clear your cookies if you have a working session), the login form is (was?) broken, the API endpoint for the login kept returning a 404 status code

[โ€“] [email protected] 1 points 1 year ago

But the cookies are set just for the path

[โ€“] [email protected] 1 points 1 year ago (1 children)

Mh.. the login endpoint seems to work

Could you please share some more information?

[โ€“] [email protected] 2 points 1 year ago* (last edited 1 year ago) (1 children)

Mhโ€ฆ the login endpoint seems to work

Yes, only now, shortly before I typed that comment the endpoint always returned a 404 error.

Could you please share some more information?

It was a server-side error, many users in the comments confirmed it multiple times and it was a bit surprising that none were acknowledged: it had nothing to do with browser cache or cookies, the login was broken. Ruud finally acknowledged that it's a bug related to closing registrations. Apparently closing them prevents user login.

[โ€“] [email protected] 3 points 1 year ago

I'm sorry, you are absolutely right!
He was working on a different issue, but I honestly didn't give them much attention because I was investigating the cookie issue.

The issue regarding the API endpoint could be "fixed" by reenabling the registration.
The still-existing cookie issue is reported (https://github.com/LemmyNet/lemmy-ui/issues/1740) and @[email protected] even fixed it already (https://github.com/LemmyNet/lemmy-ui/pull/1741)
We're now just waiting for it to get merged Blobcat bongo
