    btw, I've been thinking about ways to solve s2s connection issues (and push notifications) with MUC/XEP-0045 in ways that are mostly invisible to the clients participating in the MUC. I wrote up a 1,900 word very rough form of a XEP, and will probably look at converting that into a "proper" ProtoXEP soon :)

  331. eta

    the basic idea is to have the user's server perform MUC Self-Ping on the users' behalf and intelligently handle rejoining & history replay for the client, removing the need for the client to support such logic

  332. eta

    MUC servers must implement Unique and Stable Stanza IDs for the catchup to work, and are strongly advised to implement MAM and the optimization parts of MUC Self-Ping (but these aren't hard requirements)

  333. jonas’

    eta, that doesn’t solve all of the issues

  334. jonas’


  335. moparisthebest

    eta: is that prosody mod_minimix ?

  336. jonas’

    but it improves the situation

  337. eta

    jonas’, do tell

  338. eta

    what issues remain?

  339. eta

    moparisthebest, no, it's something different

  340. sonny has left

  341. jonas’

    eta, ah, well, if you force servers to do MAM catchup and replay on behalf of their users, that’s good

  342. jonas’

    otherwise this won’t quite work

  343. Zash

    jonas’, wanna write down all the issues on the wiki or such?

  344. jonas’

    Zash, -EBUSY

  345. Zash


  346. eta

    jonas’, so how I've spec'd it is that if your client conforms to this new XEP it just gets a "room oops happened, please do MAM resync" message and handles MAM itself

  347. jonas’

    I just came back from the police department (which was already closed) and that kind of stole more of my time than I had budgeted for

  348. eta

    if your client doesn't advertise support, the server will do MAM for you and forward the messages

  349. jonas’

    eta, ah, that’s not at all "invisible to clients" then

  350. jonas’

    and not much of an improvement over self-ping, is it?

  351. jonas’

    why not always let the server do MAM?

  352. eta

    jonas’, because paging

  353. jonas’

    I don’t folloo

  354. jonas’

    I don’t follow

  355. eta

    let's say you're disconnected for an extended period and miss out on like 1000 lines of history

  356. jonas’


  357. eta

    now the server will perform MAM to filter through that to see if any of those lines contain your nickname (for push purposes)

  358. eta

    but it won't want to buffer all 1000 and send them to you, because that drains the server's resources unnecessarily

  359. jonas’

    but if a client doesn’t support it, the server still has to do it, right?

  360. eta

    yeah, so there's a limit

  361. jonas’

    I don’t like that

  362. jonas’

    don’t hide issues if you can’t hide them completely

  363. Zash

    Will perform MAM ... when?

  364. Zash


  365. jonas’

    Zash, after MUC self-ping errored

  366. eta

    Zash, upon reconnect

  367. Zash

    Polling? Hmmmm, not sure if like

  368. eta

    Zash, polling is required

  369. undefined has joined

  370. lovetox has left

  371. eta copy-paste

  372. jonas’

    ok, well

  373. eta

    "Fundamentally, due to the way s2s links work (i.e. they get suspended on lack of activity), we'll always need to perform some kind of polling to make sure we're still in a MUC. Doing things like the server proactively saying it's back and clients should rejoin is *good*, but it'll never cover all cases due to the nature of networking. Therefore, it's probably a good idea to have a user-configurable polling interval that defaults to something like "10 minutes since last activity observed to/from the MUC" that people can tweak if they really care about knowing about disruption earlier."

  374. jonas’

    I shall write stuff down later

  375. eta

    Zash, also this is a strict improvement upon the status quo, right

  376. jonas’


  377. eta

    clients currently have to poll anyways

  378. eta

    it's better if the server does it once than having all connected resources do it

  379. jonas’

    if you hide message loss (the > 1000 messages situation), that’s not an improvement

  380. eta

    jonas’, it's not hidden

  381. jonas’

    how is it not hidden?

  382. eta

    jonas’, you either support the XEP, in which case you get an explicit "do a MAM resync" notification, or you don't, in which case you just get kicked

  383. jonas’

    if the client does not advertise support, servers will simply not send all of the history, but fake as if the client had been in the room all the time.

  384. eta

    no, they won't

  385. eta

    it kicks you in that case

  386. jonas’


  387. undefined has left

  388. jonas’

    what about the MAM stuff you said earlier then?

  389. eta

    so it tries to do a catchup

  390. jonas’

    ah, and if that’s too much, you get kicked

  391. jonas’

    makes sense

  392. eta


  393. eta

    and then you just do whatever retry logic you currently do

  394. sonny has joined

  395. eta

    (except it'll tell you that it kicked you for this reason, so you can instarejoin knowing that you're actually still in the MUC and just need to do MAM)

  396. Zash

    current retry logic: none

  397. MattJ

    Count me as interested, I've long thought we need to fix this on the server side, but haven't been able to put in the time to spec anything up

  398. eta

    I mean I'll write this up into a proper protoXEP at some point soon once I figure out how to do that

  399. eta

    the current doc is somewhat incoherent

  400. MattJ

    Step 1: obtaint markdown-to-xep

  401. MattJ

    Step 1: obtain markdown-to-xep

  402. eta

    if there are no glaring issues with it, I'll probably forge ahead with trying to write prosody modules

  403. eta

    oh yeah, the other thing I forgot to mention is

  404. jonas’

    eta, ok, that makes much more sense.

  405. eta

    this XEP has bookmarks2 as a hard dependency

  406. MattJ


  407. jonas’

    eta, I’ll be happy to help you through the XEP process -- let me know if you need any technical help in getting this in the right format

  408. jonas’

    speaking of right format: MattJ, do you have it on your todo list to clean up the new mam-forked XEPs?

  409. eta

    basically the flow is without a bookmarks2 entry for a room, you don't get any server fanciness

  410. MattJ

    jonas’, what needs cleanup specifically?

  411. eta

    so to engage the fanciness, you join normally, then add a bookmarks2 entry

  412. jonas’

    MattJ, they are lacking some RECOMMENDED/REQUIRED sections IIRC

  413. eta

    (at which point the fun state machine specified in the XEP kicks into action and joins another resource that the server controls)

  414. MattJ

    Ok, that wasn't on my todo but I can look into it

  415. MattJ

    Probably not for a couple of weeks though

  416. jonas’

    MattJ, I see, thanks nontheless

  417. jonas’

    nothing too urgent anyways

  418. eta

    once the fun durable mode is engaged, you never get kicked out of the XEP unless (a) someone actually /kick-ed you or (b) the server gave up retrying to get you back in (usually after like a day)

  419. eta

    once the fun durable mode is engaged, you never get kicked out of the MUC unless (a) someone actually /kick-ed you or (b) the server gave up retrying to get you back in (usually after like a day)

  420. eta

    in both cases, something is shoved in the bookmarks2 entry to say "this MUC is broken", which disengages the fanciness until you remove that by manually rejoining and re-adding the bookmarks2 entry

  421. jonas’

    eta, I’m sure I can read that in the document later on, but what happens if the user sends a message while they are not fully connected?

  422. eta

    jonas’, what do you mean by "not fully connected"

  423. jonas’

    eta, the server is currently in the process of retrying to get you connected

  424. jonas’

    eta, the server is currently in the process of retrying to get you connected to the MUC

  425. eta

    jonas’, you get an error of type "wait"

  426. eta

    the one smoking gun might be if current clients decide to rejoin the MUC in this case, which would suck a lot

  427. eta

    well, actually, no it really wouldnt'

  428. eta

    well, actually, no it really wouldn't

  429. jonas’

    that depends on the specific condition, but a server could easily eat rejoins away in such cases.

  430. alexis has joined

  431. adiaholic_ has left

  432. adiaholic_ has joined

  433. eta

    jonas’, it kinda does

  434. eta

    if you attempt to rejoin whilst in the `Reconnecting` state, what happens is it marks you as "waiting to rejoin", eats your presence, and sends you a "experiencing connection issues" message (for conformant clients)

  435. eta

    if it manages to get you to join, it forwards you the recipient list and then does the "intelligent catchup" process

  436. eta

    actually wait, no, it wouldn't do that because you'd be expected to do MAM anyway, so scratch that

  437. MattJ

    Bonus points for a state diagram :)

  438. eta


  439. eta

    MattJ, 👀️

  440. MattJ

    Bonus points awarded, achievement unlocked!

  441. eta

    the nice thing is, if this XEP actually becomes a thing the UX will probably be better than something like matrix

  442. eta

    because you'll get an explicit "experiencing connection issues" display in your client's UI

  443. eta

    (which I think is a lot nicer than just sending and not getting any messages back until s2s reconnects and everything floods back in)

  444. eta

    also, there's no requirement to implement a bloody complicated MIX server

  445. eta

    like all you need on the conference service side of things is MUC, unique and stable stanza IDs, (MUC Self-Ping optimization, MAM)

  446. jonas’

    it makes MUC better, but it doesn’t solve other problems of MUC ;)

  447. eta

    so I can write my transports and have them work :p

  448. jonas’

    in fact, this is something MIX also still needs to solve, so I think that work is valuable

  449. eta

    jonas’, what are the other problems though?!

  450. eta

    oh, MIX

  451. eta


  452. jonas’

    no, your proposed thing

  453. eta

    okay, what other problems are there

  454. jonas’

    try to address a specific resource of a participant in a MUC

  455. eta

    what's the usecase for that?

  456. jonas’

    the entire multi-session nick hack which isn’t written down anywhere normative

  457. jonas’

    eta, sending IQs

  458. eta


  459. eta

    oh yeah, re nicks, you can't specify one on join any more

  460. eta

    it forces it to be your bookmarks2 one if you have one in bookmarks2

  461. jonas’

    I need to step away for a bit, I’m having a hard time to concentrate on anything

  462. eta


  463. eta

    eta - out of curiosity - why not push for MIX addotion, instaed of putting another patch on a MUC?

  557. eta

    Wojtek, I think MIX is overengineered

  558. Wojtek

    and yet another patch on (kinda broken) MUC is better?

  559. moparisthebest

    only one can be used without all servers upgrading at once

  560. eta


  561. eta

    MIX isn't backwards-compatible with MUC

  562. eta

    MUC is a very simple standard, and I like that

  563. jonas’

    Wojtek, MIX also has exactly the same issue

  564. jonas’

    (not quite exactly, but well)

  565. alexis has left

  566. jonas’

    eta, MIX does have a MUC compatibility layer which I’d deem "good enough" for a soft transition

  567. eta

    jonas’, okay, but also

  568. Wojtek

    eta: XEP-0408?

  569. eta

    MIX creates an ecosystem split where half the users still have a crap experience

  570. moparisthebest

    in tigase's defense they *actually* put in the work and seem to have made a seemingly working implementation, I'll have to update https://www.moparisthebest.com/mix/

  571. eta

    even with a compatibility layer

  572. jonas’

    eta, that’s life.

  573. eta

    jonas’, no, but it doesn't have to be this way

  574. krauq has left

  575. krauq has joined

  576. jonas’

    eta, yes, hence I’d actually suggest putting energy into MIX -- but I don’t blame *you*, because the work you’re doing we need for MIX, too

  577. jonas’

    we discussed about that in this very room just the other day

  578. eta

    yeah, I saw :)

  579. eta

    Wojtek, okay, point taken

  580. Wojtek

    eta, MUC may be a simple standard yet time and time again there are problems with it and (weird ways) to fix that...

  581. jonas’

    MUC is by no means a simple standard

  582. Wojtek

    @jonas’ what same issue?

  583. jonas’

    Wojtek, dealing with s2s outages

  584. jonas’

    clients need to know about it to sync their archive with the remote MAM (if we go for remote-archives-only) and/or servers need to sync the user’s MAM and do magic if we allow for user-local archives

  585. Andrzej

    eta, MUC is simple? try to make it scalable, consistent, etc. you will learn that it is not so simple

  586. eta

    it's simple if you're a transport developer :>

  587. jonas’

    eta, MUC is a very long document as it stands already. Aside from that, there are hacks upon hacks which aren’t even *documented* there (like the whole multi-session nick stuff, or IQ routing in MUC in general)

  588. Wojtek

    @jonas’ if we *don't* allow you mean? beacause with local archive each time there is a new message it's delivered to local archive which eliminates issue with s2s outages

  589. eta

    and MIX solves this problem?

  590. jonas’

    Wojtek, no, if we *do* allow.

  591. jonas’

    Wojtek, that’s not correct. what if the s2s between MIX and user server is down?

  592. jonas’

    eta, yes, because MSN (multi-session nicks) as well as IQ routing (by having each resource addressable) are both well-defined in MIX

  593. Wojtek

    then your local archive won't get the message, but you also won't be able to query it ;-)

  594. jonas’

    Wojtek, yeah, so you have message loss (bad)

  595. Wojtek

    but I get it now

  596. Wojtek

    still, I don't recall fallback to query remote server if `urn:xmpp:mix:pam:2#archive` was advertised

  597. jonas’

    it’s a rather tricky thing to solve. It’s not just that servers do MAM syncs among each other. To ensure correct order of message delivery, servers will also have to do replay from MAM as well as queue "live" messages

  598. jonas’

    Wojtek, sorry, I lack context, what does `urn:xmpp:mix:pam:2#archive` mean and who would fallback to what?

  599. Wojtek

    "Archive of MIX channel messages MAY be performed by the participant's server. When this is done, the capability is advertized to MIX clients using the 'urn:xmpp:mix:pam:2#archive' feature. If archive is provided it **MUST always be used**, so that where a message is sent to the participant's server and discarded because there are no active clients, it will still be archived. This means that when archiving is provided, the messages will be available in the local archive and can be picked up by clients when they come online. "

  600. sonny has left

  601. Andrzej

    @jonas’ simples solution for s2s issues would be stream management over s2s, or force MIX to add stable-id of a last message which was sent, so that users server MAM could fill that and deliver "lost" messages as a normal MIX message with `<delay/>` element in them

  602. eta

    Andrzej, my proposed solution does the stable-id thing, sorta

  603. jonas’

    Andrzej, no, stream-management is not sufficient

  604. jonas’

    stream management will have limits because servers won’t queue forever.

  605. jonas’

    Wojtek, the text you quoted is exactly the problematic part. It claims that the user’s archive is the gold standard, but in fact it’ll have gaps without additional measures.

  606. jonas’

    Andrzej, what you propose is one of the ways to do it, but then the user server becomes quite complex. It needs to do MAM queries, backfill the local archive (which it may not be able to even to, because it’d have to insert into MAM at an earlier point, violating one of the MAM guarantees!), it has to buffer all "live" messages from the MIX to be able to replay MAM first in order to provide in-order delivery of all stanzas from the MIX.

  607. jonas’

    and it needs to do that across all pubsub-nodes the user has subscribed to on the MIX, too

  608. Andrzej

    @jonas’ we will have gaps, but it was discussed at the summit and the simples solution to add to the message stable-id of a previous message was suggested (by Kev if I recall)

  609. jonas’

    and then the client would be responsible for filling the gap in its local archive?

  610. Andrzej

    @jonas’ why it needs to insert those new entries in the past? just add them at the end with `<delay/>` element in them

  611. mukt2 has left

  612. Andrzej

    then MAM would be just log of a messages which you have received and delay timestamps would allow clients to assign those messages in proper order

  613. jonas’

    which clients don’t do generally

  614. jonas’

    and I’m also not sure if that’d be acceptable

  615. eta

    Wojtek, XEP-0408 doesn't really say much

  616. Wojtek

    I know that it's the problem, but it says that if there is local archive the user *MUST* use it (so no queryign from MIX MAM)

  617. jonas’

    Wojtek, hence the debate about that particular text :)

  618. jonas’

    eta, needs implementations. but conceptually, it can easily work.

  619. eta

    okay, so MIX removes some hacks that you need to make MUC work

  620. eta

    I mean I don't think the problems with MUC are bad enough to justify scrapping it entirely

  621. eta

    or rather, to justify the ecosystem split having 2 competing standards would cause

  622. jonas’

    that is your opinion and you can have it :)

  623. Wojtek


  624. eta


  625. eta

    if people want to implement MIX though, go ahead! part of why XMPP is great is precisely that people can have different ideas

  626. Wojtek

    and having many things of doing something is kinda "XMPP way" ;-)

  627. Andrzej

    eta, for mobile devices (ie. iOS) using MUC requires a lot of hacks

  628. jonas’

    though I *do* find it amusing, that the often-complained-about required user-server support for MIX is now coming for MUC ;)

  629. Wojtek

    for me it seems that MUC is basically mutating into MIX, in stages...

  630. eta

    Andrzej, are a lot of hacks bad though? :p

  631. Wojtek

    YES :-P

  632. eta

    Andrzej, I mean the followup XEP I was going to write is a spec for doing push notifications

  633. eta

    if the server has a resource constantly joined to the MUC, it can receive messages, match them against a set of rules / regexes, and then forward the message to the client

  634. Andrzej

    eta, with filtering I hope?

  635. jonas’

    eta, what about E2EE?

  636. eta

    Andrzej, yeah, I want to essentially rip off matrix's push rules system

  637. mukt2 has joined

  638. eta

    jonas’, you'd have to either (a) send every message or (b) include a separate <mentions/> element or w/e

  639. eta

    and deal with the privacy implications of (b)

  640. Wojtek

    > if the server has a resource constantly joined to the MUC, it can receive messages, match them against a set of rules / regexes, and then forward the message to the client so, basically permanent member subscription? like in... MIX? ;-)

  641. eta

    although *no* messenger can deal with the e2ee problem :)

  642. Andrzej

    eta, if you want to write something like that please check https://xeps.tigase.net//docs/push-notifications/filters as this could be useful

  643. lskdjf has left

  644. eta

    Andrzej, issue I have with that is, what does "mentioned" mean

  645. eta

    do I get a notification any time someone says "details"? ;P

  646. Mikaela has left

  647. moparisthebest

    it means you can silently eat the mobile battery of everyone you are in a channel with of course :)

  648. lskdjf has joined

  649. Andrzej

    mentioned means that your nickname was mentioned in a message

  650. eta

    Andrzej, no, sure, but how are you matching

  651. eta

    if your test is `string.contains(nick)` it's going to break for me :)

  652. Andrzej

    contains and check if before and after there is no alphanumeric character

  653. eta

    ah, good

  654. eta

    that aside, though, yeah, that XEP looks very similar

  655. eta

    Wojtek, yeah, exactly like in MIX :p

  656. Andrzej

    I was suggesting to consider just requirements from our XEP (and syntax if that would be useful)

  657. eta

    like I don't think MUC's current semantics are ideal at all

  658. eta

    Wojtek, the difference is my proposed XEP doesn't require the MUC service to support much more

  659. Andrzej

    but requires local server to keep a persistent session for you

  660. eta


  661. Andrzej

    with S2S issues, reconnections, MUC restarts, etc. this can be problematic

  662. eta

    Andrzej, that's what the whole XEP is about

  663. eta

    you could even extend it to have local archiving semantics similar to your MIX implementation

  664. eta

    it just won't do that initially because that's a bit of a hard sell for some server operators

  665. eta

    generally my problem with MIX is it doesn't really obey Postel's Law (https://en.wikipedia.org/wiki/Robustness_principle): it requires there to be a shiny new MIX service out there to get any of the benefits

  666. eta

    whereas trying to patch MUC on the server side will improve experience for ~90% of users without them having to change client or MUC service

  667. eta

    that said, for non federating environments, MIX is unquestionably better

  668. Mikaela has joined

  669. Wojtek

    and then you end up in a situaiton when some server support that and some not and some user will have different experience than others... and then everyone complain again that it's impossible to have more-or-less consisten experience with XMPP and jump on the matrix badwagon

  670. moparisthebest

    not sure that's the right law, it requires a flag-day, which never ends up happening

  671. debacle has left

  672. moparisthebest


  673. eta

    Wojtek: well no, you make it part of the compliance tester

  674. eta

    also I mean, MIX has the same issue!

  675. eta

    (in fact it's worse)

  676. moparisthebest

    huh TIL that flag day was also Postel's https://tools.ietf.org/html/rfc801 :)

  677. sonny has joined

  678. Wojtek

    compliance server is run by a private person and not XSF… and it's kinda arbitrary - it requires XEP-0215 yet compliance suite doesn't mention this particular XEP...

  679. jonas’

    it also doesn’t say XMPP or XSF compliance ;)

  680. Daniel

    The compliance tester is just 4 month ahead of time

  681. eta

    Wojtek: well, I mean I'd be interested to hear your solution here

  692. lovetox

    there is no server that supports bookmarks2 in a way that client would want to use it

  693. eta

    lovetox: but bookmarks2 defines a private XML conversion path

  694. eta

    lovetox: oh? what are the issues with bookmarks2?

  695. lovetox

    hm? i didnt say there where issues with bookmarks2, only that no server supports it

  696. eta


  697. lovetox

    and bookmarks2 in turn depends on other XEPs that servers dont support

  698. jonas’

    does it?

    The irony is that the original "XSF Martin" that caused you to switch to that nick... I'm pretty sure he was never a member of the XSF :)

  832. jonas’


  833. jonas’

    but he was in board, right?

  834. eta . o O ( I should join the XSF )

  835. MattJ

    jonas’: yes

  836. jonas’

    ok, that explains my assumptions (and I suppose also mdosch’s)

  837. eta

    how do clients typically advertise support for some XEP?

  838. jonas’

    eta, XEP-0030

  839. APach has left

  840. eta

    jonas’, right, so the server is expected to do the whole entity caps dance and disco#info query it?

  841. jonas’

    yes, servers do that anyways tho

  842. jonas’

    for PEP

  843. eta

    oh, okay, so that's something we can build on

  844. jonas’

    so just state that the client has to implement XEP-0115 and go ahead

  845. eta adds more dependencies
