upgrade: lemmy 0.19.2 + infrastructure [clear your browser cache and cookies!]

today's (later than planned) upgrade to lemmy 0.19.2 provisionally appears to have gone alright. if you see excessive amounts of jank (and your page footer can't decide what version of lemmy it's running on, IE it shows separate FE and BE versions), clear your browser cache and cookies since lemmy doesn't seem to do that cleanly on its own

next up I'm planning to deploy the Proton frontend as an alternative to the default and I'm also going to start pushing code to codeberg (most likely) so stay tuned for that

In today's episode of awful systems I found outt my phone's browser can't manage individual site cookies. Deleting them is an all-or-nothing deal.
Tfw the mono no aware hits you when you have to log out of everything just to make fun of techbros.
- christ I’m sorry. my phone probably needs the same — the mother fucking cache-control immutable header some lemmy dev decided to hardcode into lemmy-ui’s app server seems to have triggered a bug in my phone where I’m both logged in and not simultaneously, and switching tab groups logs me out until I open a new tab
  since all this unpleasantness is due to a bad cache-control header, hopefully it should all clear up when caches expire and pull in the new version of the site and corrected cache settings… in like 20 hours. fuck
  
  They were using immutable cache control headers on resources that were, in fact, mutable? Uh oh.
  
  Haha wow, now it's hitting me with the same thing I think. Keeps logging me out randomly and putting me in a state of Schrödinger's session cookie.
  All hail the jank!
  Edit: seems to happen if I refresh the page.
  
  Only two hard problems in CS: cache invalidation, naming things and off-by-one errors. But especially cache invalidation and especially especially when you make it even harder lol.
  
  no such luck lol
- this is also in Chromium for desktop
- This happened to me with mobile Firefox too, RIP my sessions

this is what happens when you piss off elite hackers like musk and yudkowsky
- "Too many microservices!"
  
  And we will finally stop showing version numbers below every page here on awful.systems (waste of screen space & compute). Literally everyone knows lemmy never breaks during upgrades …

Not sure if this is related, but any time I try to upvote or downvote a comment, I get this error:
undefined

Error: invalid_bot_action
- huh, I’ve never seen that before. let me look into this new jank (maybe your account somehow got marked as a bot account?)
  
  fucking waaaaait is that why there’s a B next to your name? check your profile page and see if the “user is a bot” checkbox is enabled

I have used my immense technical skills nurtured over the course of decades to bypass the error page.
I am pleased to report that I have successfully cleared my cookies.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
- same

Looks like it reset 2fa on accounts, as well
- checked the patch notes and that part is intentional. there was apparently bad 2fa UI before, which got people locked out, the reset is intended to rescue their accounts

I’m impressed by the way some threads now have "-2" new comments. How does that work?
- acausal trade

Sharing just in case anyone else needs to see it - Safari on Mac gave me all of those login / logout things, and would not show any posts at all, just an error screen. I couldn't even see this note to know what the problem was, even when refreshing. I went to a clean Firefox browser, saw this, cleared Safari history and all is well.
Mac / OSX Sonoma.

I've deployed a fix for the JWT bug that's been breaking all our users, as well as the broken cache behavior. special thanks to the lemm.ee infrastructure admin/professional software developer/lemmy contributor below who bravely sacrificed their posting privileges by pointing out the source of the cache problem in the most jackass way possible and then insisting on a solution that doesn't work for our instance
there's one remaining lemmy-ui bug on my end I haven't been able to track down, and that's the weird half-logged-in session thing where depending on how you interact with the page, your session might disappear. that one stumps me to be honest; I'm going to try and debug with dev tools later, since currently it's only happening in Safari on my phone.

Just in case anyone else runs into it: looks like this issue also completely wedged my install of Mlem - had to nuke the app from phone and reinstall, its sign-in procedure didn’t cope with this failure mode and it had no way to forget about account without also wanting to remotely delete an account (which I figure probably would’ve failed because no auth token, but I didn’t chance it)
I’ll log a bug their side when I have some headspace to write it up

this is wild, i can successfully log in and everything is fine in a chromium incognito window but not in a normal window even after clearing cookies and cache
EDIT: chrome://settings/content/all shows the cookie and I can delete it
firefox works after i just clear the cache
MOBILE SUGGESTION: if you have android, why aren't you using firefox with ublock origin already
lemmy on urbit on windows

I humbly ask that you do not update the UI from 0.18.4, because pagination of comments is disabled? broken? with this update.
Alternatively, if you did update to 0.19.2 FE, and I still see the old functionality because of my cache+cookies, then the jank is even more powerful than I imagined.
- the jank is extremely powerful, and it sounds like you’re running a mix of 0.18.4’s libraries and 0.19.2’s html and css right now. see elsewhere in this thread for the extremely drunk programming mistake some lemmy dev made that causes this
  clearing your browser cache and cookies should get you a fully working lemmy UI, I hope (maybe try lemmy.ml first to see if pagination is working as expected on your end; they should be on the same version as us)
  
  Nope, cleared cache and cookies for lemm.ee and the pagination for comments is still not working. Must be a bug with lemmy, pagination for posts works fine.
