Does anyone know if jsxc supports rtcp-mux and jingle grouping framework?

Жокир Even if they're not used now, or not used in XEPs that are published now, there's a chance that they'll be included in the future. Does ignoring them now give you a significant advantage somehwere? If not, I'd just keep supporting them.

rion, probably, given these two extensions are mandatory for WebRTC and this is a web client.

But I’ve never managed to setup this client.

What stanza size limits do clients and servers usually impose?

Жокир, can you change your nickname to have ascii as the first letter? It is hard to reply to you for people with ascii-only keyboards (most of the people here)

Done

nope

still Жокир

Oh

jonas’, since you’re using poezio, you can tab without writing a first letter.

Link Mauve, that’s how I’ve been doing it, but it’s meh if they haven’t been the last one to talk

It will complete with nicks in reverse chronological order of who last spoke.

Indeed, the other option is to copy/paste the nick using e.g. your terminal.

Conversations tells me the nickname is changed. Nothing I can do til I reach my desktop I suppose

pity

Жокир, to answer your question, I have yet to see an enforced stanza size limit

the RFC guarantees 10 kB

> I have yet to see an enforced stanza size limit So even servers don't enforce a limit? Wouldn't that make DoS attacks easy?

yes

servers have to enforce a limit or they are vulnerable, I'm not sure if any servers actually do though...

Some servers do I think

I thought we set a 10MB limit in Prosody

Yeah I've seen logs saying "Stanza too big"

Zash: Oh 10 *M*? Somehow I seemed to remember you set the RFC's 10 *k* by default.

Holger, 10k is the smallest you're allowed to limit to

Openfire has a configurable parse buffer. Defaults to 1M

funny timing, I actually wrote a program to test this the other day, and balooned my prosody memory use from 60mb to 2.6gb, was going to report but realized I'm on a fairly old version of prosody, so want to upgrade first and test again

Zash: Yeah, I thought you're doing that.

This is also why we choose 10MB as HTTP body size limit.
