XSF Discussion - 2020-10-27

Apart from XEP-0313, does anyone know other features that the client must disco their account to discover?

Carbons?

vCard conversion?

And bookmarks conversions, all three of them?

Not carbons, according to the XEP

Also PEP stuff most likely.

It's just come to my attention that this stuff isn't covered by the caps we put in stream:features

True

Also account vs host features is weird

That's the discussion I'm having with a client dev right now :/

put user caps string too in stream:features?

Can you?

Post-SASL?

Seems like a sensible solution, obviously you need to differentiate the two somehow

Zash, probably even in sasl's <success/>

add an @address attribute to <caps/>?

so that you can have multiple in <stream:features/>?

I hear '390 is still experimental

jonas’, do it

and then we can shove in subdomains as well :)

+1

I had some ideas around a recursive disco#items-like thing that'd include caps of its items

(nothing to see here) ✏

MattJ, related: https://github.com/xsf/xeps/pull/924

IMO account is the logical entity

but there is some prior art in the other direction

Uh, fun

Yes, 191 was the first I checked actually when looking for "proof" :)

fun fact: I made that PR because of a deployment where '191 is *not* available for all accounts

jonas’: Breaking change to a Draft XEP? Mmmmmmmm

Zash, good point :)

Holger, do you know if ejabberd advertises MAM on the server JID?

I guess an XML console can tell me

unless it replies differently to remote users

MattJ, yes MAM is advertised both on the server and account JID.

I think an older revision mandated the server JID? Or some client(s) assumed it ... 😕

Seems some clients definitely assume it :(

I don't know about older XEP revisions

Apparently Openfire is also guilty of this

I want one of these to be combined with "and if you sent a MAM query to the server JID, a local user can access all messages that the server has seen"

> Apparently Openfire is also guilty of this I think it's our specs fault 🙂 My impression was we were moving from server to account JID (where it makes sense), but only half-heartedly. IIRC I PRd against multiple XEP examples that got it wrong and stuff.

Makes sense

Also e.g. https://xmpp.org/extensions/attic/xep-0359-0.5.0.html#disco vs. https://xmpp.org/extensions/xep-0359.html#disco ... and I'm pretty sure there's more such examples.
