💀 Mirko 💀 (on fedi vacation)Feb 20

#Challenge

My #Mastodon instance has a 5000 character limit. Who can find me a text from anywhere in the #Fediverse breaking this limit?

I know, that #Friendica and #Hubzilla have theoretically no character limit. But what's the point of bragging about it, when nobody is actually using it?

#Sharkey - as i think all #Misskey forks do - is limited to 3000 characters. Still, more than 99% of the Fediverse really is using.

And please, take a real single posting at least a couple of days old, not some crappy merged text to prove me wrong.

Boosts welcome. 🔄

@m1rk0 Kind of challenged by this question, I messed around with certain text tools to count chars on some of my older blog posts and noticed that the longer ones easily exceed this length. Probably, so, most likely candidates for this are people actually using Fediverse instances as full-blown blogging platforms, maybe also as a replacement for systems such as Substack (if anyone does that at all). Whether the mix-and-match of longform and shortform posts without really taking expected post length into consideration is a good thing from other points of view (usability/accessibility) might remain a question of its own.

(If you can't open either of these links, say so, and I'll reply with full quote-posts of these three posts.)

All character counts are raw, i.e. the actual number of characters visible. The characters are not counted the Mastodon way (= summary/CW counts into the character count, links are always 23 characters). BBcode markup is not counted in either, nor are the alt-texts, although both internally add to the character count.

Important to know: Local character limits aren't necessarily inbound character limits. For example, Mastodon is hard-coded to a maximum of 500 characters internally, but (AFAIK) it accepts posts coming in from outside up to 100,000 characters.

Likewise, Misskey is hard-coded to 3,000 characters internally. The Forkeys have a configurable internal character limit. But their inbound character limit is higher, hard-coded to ca. 8,000 as @aliceif :totally_a_real_lesbian_flag: has said.

Pleroma and Akkoma have configurable internal character limits that default to 5,000, but AFAIK a hard-coded inbound character limit of 20,000.

In all these cases, longer posts coming in from outside are immediately deleted from the inbox.

@jupiter_rowland Thanks for the pointers. Just to be clear:

In all these cases, longer posts coming in from outside are immediately deleted from the inbox.

Do I read that right? Like, I do have federated systems that just quietly discard communication from my inbox if it exceeds a certain internal limit (that is not even visible to me as a user) even without this removal being visible to either recipient or sender?

@Kristian 🌒 @💀 Mirko 💀 @aliceif :totally_a_real_lesbian_flag: As far as I know, yes.

They don't even reject these posts. If they did, I'd be able to see that in the delivery report. But they actually do let these posts in, check the length and then delete them before forwarding them to inboxes, something that Hubzilla, (streams) and Forte don't notice.

I'm not sure if that's limited to Note-type objects, though. But Hubzilla has no way to send Article-type objects, not even optionally, because the devs refuse to re-implement it unless Mastodon starts supporting full HTML rendering with all bells and whistles and gives up that title-summary-and-link-to-the-original hack.

@jupiter_rowland Good god what a mess.😔 I know that reliability of delivery and delivery status insight is basically nonexistant for arbitrary users on every platform except Hubzilla. But this is even worse, and I wonder how people implementing this kind of stuff would respond to the idea of MTAs quietly discarding e-mails that exceed a certain size. It seems at some point we have just given up on reliable behaviour in architecture of such systems. 😔

@[email protected] @[email protected] @m1rk0 no, Misskey is (imo) worse: it takes longer posts and chops them off at ~8000 - with no indication that it happened other than the text ending abruptly.

@[email protected] @[email protected] @m1rk0 what misskey annoyingly also has is an alt text length limit (which also cuts off alt text after a certain length) - which has a bug than can cause posts to be unable to be received due to a database limitation:
https://github.com/misskey-dev/misskey/issues/16208
Incorrect length adjustment for drive_file comment field · Issue #16208 · misskey-dev/misskey

💡 Summary When I lookup a post with a file that has an alt text with over 512 characters that uses special characters like combined emoji characters, Misskey truncates that text to 512 characters. ...

@aliceif That's rather ugly as well, but feels more in-line with Mastodon only showing off four picture attachments with posts, leaving no trace if/whether there are more than that (as seen in pixelfed or Friendica which don't impose this kind of limitation). However, I still feel quietly deleting conversations without notifying either recipient or sender to be about the worst and most hostile design move one can probably do in a decentralized environment. It basically strips these systems of any trustworthiness. 😔
