whee memcache: missing comments ftl

[azurelunatic]

Source of the missing comment problem found: Memcache issues.

When two database servers are very, very busy, sometimes one doesn't talk to the other one. And sometimes, the other one has no idea that someone left a comment just five minutes ago.

It's not the same comment rot as IJ had, which is a relief.

I kinda suspected that when I noticed that comment numbers weren't matching up with the actual number of displayed comments. =/

Also... I'm wondering if anyone's noticing similar wonkiness with Friends list/Members list numbers. >.> I recently deleted a purged community from my Friends list, but the number stayed the same for a while. And there are a few other communities I've been watching the Members count on, but... yeah, they're not in sync.

I know there was some weirdness with that on Dreamwidth when that wasn't being memcached there.

Yes, that would also include Friends & Member list numbers.

What was/is the cause behind IJ'd comment rot?

[azurelunatic]

An old legacy hack: the setting $NEW_ENTRY_CLEANUP_HACK.

Symptoms included actual data loss, rather than temporary "data? what data?" problems.

And it took a really long time to fix, because it was tricky and squeaky's only one man with a day job.

That explains the mess with a few of my comms and my comments. Thanks for the notice. :)

[azurelunatic]

You're welcome!

Yeah, I'm really glad they found the reason. It was getting weird. *g*

[azurelunatic]

So am I! Though sometimes the effects create kind of hilarious things with people appearing to be talking to themselves.

I just wasn't getting any comments because nobody loves me! *cries himself to sleep*
