XSF Discussion - 2018-04-04

nice and so I managed to send the error on the wrong stream...

luckily it's fixed, all the blame goes on the flow scheme in {xep 220} that always confused me to hell.

Maranda: Server Dialback (Standards Track, Draft, 2015-03-12) See: https://xmpp.org/extensions/xep-0220.html

Saw this on hn last night and had never heard of it: https://tox.chat/

https://news.ycombinator.com/item?id=16750265 that comment made me really sad. And it doesn't even look like sarcasm...

> Prosody is very simple to set up, ejabberd can scale to infinity.

… and beyond

Faster than the speed of light!

objection!

erlang makes your CPU runs faster

That doesn't compute

And I broke bidi ™️

maybe you need a better compute-r

How I don't have a clue (yet) ™️

Aka never try to untagle messy code at 2:30 am.

s/untagle/untangle/

And found it

Maranda, I've got a broken bidi in Metre as well. It's deceptively tricky to get right.

dwd: it's not bidi being broke, I broke mod_s2s which broke everything not just bidi, just because "mark connected" expects an event to return "true" and that is not there anymore yay \o/

Oh, fun.

Let's hope no s2s stream closes before I'm home again.

s/mark connected/make authenticated/

dwd, good news is that I think I _finally_ managed to fix and untangle (most of) that mess that is s2s/dialback code.

(Dialback expecially)

Metre is basically all S2S code, so I can appreciate that.

dwd: Have you tried Metre with Prosody ?

And there we go...

The more I think about the account-MUC-bouncer and some kind of extended notification mechanism, the more I like it.

:O

have you figured out a proper way of dealing with MUC service reboots and s2s errors yet?

jonasw: there is none. But at least the server should know when s2s errors happen

Ge0rG, syncing from one MAM to the other could work.

MAM-to-MAM transfer!

it doesn’t solve the JID hack tohugh

DMA, direct MAM access.

which JID hack?

the JID hack which is called MUC

Hm. Maybe.

you know, where resources of a JID represent entirely different identities

I've learned to live with that hack

yeah, and you love the difficulites arising from PMs and such due to that :)

the MSN things

Querying your contacts MAM for your own messages there could be ... a thing.

Hm. Why doesn't my yaxim synchronize any more.

But you know, that's in "Skype behaviour I hate" land. Don't do it!

Does it crash during startup?

Maranda: no, it fails to join IRC channels.

😎

Gotta crash a few times while querying your contacts online clients for history.

And get the history in random order.

\o/

> But at least the server should know when s2s errors happen Nope, not really.

Kev: *better than the client

From the school of 'that's not saying much' :)

I'm not sure I should use either when rejecting a db:request from a blacklisted entity, I suppose not-allowed would be more appropriate.

Dave Cridland, well bidi on dave.cridland.net doesn't look broken to me at a first glance at least fwiw

(and/or dwd XD)

Maranda, It's not always broken. There's some sequence which causes it to choke.

Dave Cridland, I think I can make an educated guess some of those involve DB 🤣

Maranda, To some extent. But I think it's more that it sometimes removes the session that's just gone bidi by accident. I thought I'd stopped it, but I think there's still some odd cases.

and there I knew something was amiss, *hates being right*

Dave Cridland, Does Metre do some sort of "caching" magic if I previously authenticated a stream via SASL external and I close the stream and reopen a new one and use dialback instead that time?

Maranda, Not sure I know what you mean. It doesn't change behaviour dependent on previous sessions (yet).

Maranda, But it'll respond to dialback based on whether it can authenticate the session. Not whether it can authenticate it via dialback.

Dave Cridland, I don't see it verifying dialback keys that's what I mean.

Maranda, Right, but if the remote session has a valid certificate, there's no need.

Maranda, See XEP-0344.

hmm ok noted

since there's scarce bidi deployment out there I wanted to check if Metronome actually opened a new stream to verify keys (which I somehow doubt it doing on outgoing streams for some reason) :)
