TOPIC REFERENCE: OpenAI / ChatGPT had a bug a month ago where an open source library would mix up session data and present users with session history from other users. It took them several attempts to fix it.
I’m seeing problems like that this week on Lemmy.ml
When I would refresh my webapp page, my username would appear as someone else in the upper right and then change itself again to my username.
I was on a single Community page: https://lemmy.ml/c/smhistory and postings from other communities started to stream into the page on their own, 3 new postings appeared in a matter of seconds.
Vote counts often appear wrong when opening a posting page such as the page you are on to read this posting. A browser refresh often corrects it.
Something is going wrong within the code somewhere as to which server data is being sent to which client. It seems to be impacting multiple functions within the site, I expect some common code library or technique with login session data.
The upvote count seems to be where it happens most frequently. Today was the first (and so far only) time I saw where a Community started to show postings from the wrong communities… I can’t reproduce that so far, but it is what inspired the post because it seems like a common issue with session keys getting mixed up.
I know currently they are using websockets to send fresh data to clients and they are phasing that out, so maybe the move away from websocket will avoid the problem.
