XSF Discussion - 2022-11-25

21:17:20]<Zash> I note that Converse.js won't show a message input box if you open a chat with a host jid (without localpart), which made it awkward when I made a chat interface for pubsub bnw.im is an example of an XMPP service that sends and receives messages on its host jid

(xmpp-based blog)

So is xmpp:cheogram.com

and xmpp:pubsub.prosody.im

mjk, I hope not, as this production would disallow 'dot' U+002E in the domainpart, which would invalidate all JIDs in this MUC

(well probably depends on how you interpret what a "string conforming to RFC 5890" constitutes)

flow: I'd think it means not just a label

mjk, well, then check § 3.2.1 of said document

of 5890? there isn't a 3.2.1 in 5890...

https://datatracker.ietf.org/doc/html/rfc7622#section-3.2.1

oh

mjk, also related https://www.rfc-editor.org/errata/eid5789

(which is incomplete, as I learned later that there are more DNS label separators than U+002E, which should probably be mapped to U+002E) ✏

ok, so the RFC says not what it means, all clear now :)

the intention is clear, you want to allow internationalized DNS names, IPv4/v6 addresses and "hostnames" (which are probably best described as internationalized DNS names without length restriction) in the domainpart

right

XMPP End of the Year talk A kind reminder on the topic and call for more short presentations (5-10 mins, informal is fine). When: 6th Dec, 19:00 CET
