XMPP 0059/0313 Archive message - paging backwards through result set - xmpp

I have gotten the last 10 messages from archive, and trying to get the 10 before that on request and so on.
On the XMPP doc. it said i set the before with my UID??
http://xmpp.org/extensions/xep-0059.html#backwards
<iq type='set' from='stpeter#jabber.org/roundabout' to='users.jabber.org' id='back1'>
<query xmlns='jabber:iq:search'>
<nick>Pete</nick>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>10</max>
<before>peter#pixyland.org</before>
</set>
</query>
</iq>
or this?? http://xmpp.org/extensions/xep-0313.html#query-paging
with some ID in the after tag? I am very confused, can anyone give me some pointer, thanks!
<iq type='set' id='q29303'>

I tried putting in before with my UID and it didnt work <before>peter#server.org</before>
ANd i have an error <error code='400' type='modify'><bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error></iq></body>
I am using strophe.js mam plugin and rsm plugin

When you receive first page limited by RSM with max=10, you will receive first and last UIDs:
<iq type='result' id='q29302'>
<fin xmlns='urn:xmpp:mam:1'>
<set xmlns='http://jabber.org/protocol/rsm'>
<first index='0'>28482-98726-73623</first>
<last>09af3-cc343-b409f</last>
<count>10</count>
</set>
</fin>
</iq>
These are UIDs of messages, which you can use in before and after subsequent queries.

I couldn't get all messages with some user with its JID

I made custom Iq for Request to Openfire server:
<iq id="7c0b34f5-d78e-48bf-819d-a357cb1f6b9e-5" type="set">
<query xmlns="urn:xmpp:mam:2" queryid="7c0b34f5-d78e-48bf-819d-a357cb1f6b9e-5" before="2022-04-29T12:00:00+00:00">
<x xmlns="jabber:x:data" type="submit">
<field var="FORM_TYPE">
<value>urn:xmpp:mam:2</value>
</field><field var="with">
<value>boki#desktop-eub4fkr</value>
</field>
</x>
</query>
</iq>
Response is only with counted messages, not with body text. Response:
<iq type="result" id="7c0b34f5-d78e-48bf-819d-a357cb1f6b9e-5" from="jid...." to="jid.../resource">
<fin xmlns="urn:xmpp:mam:2" queryid="7c0b34f5-d78e-48bf-819d-a357cb1f6b9e-5" complete="true">

I installed Monitoring Service Plugin to Openfire server. I tried with put start, end, after and before tag, but always the same result. I really don't know why... Any suggestion would be helpful

Retrieve history chat Openfire XMPP framework

I've developed a chat app using XMPPframwork of Robbie Hanson and Openfire server.
I can chat one to one and chat group successfully. But when I get history of chat, I can't get whole history. I use XEP-0136 to archieve history:
Send IQ:
<iq type="get" id="hichic#macintosh">
<retrieve
xmlns="urn:xmpp:archive" with="group12#conference.macintosh">
<set
xmlns="http://jabber.org/protocol/rsm">
<max>100</max>
</set>
</retrieve>
</iq>
Receive:
<iq type="result" id="hichic#macintosh" to="admin#macintosh/Macintosh">
<chat
xmlns="urn:xmpp:archive" with="group12#conference.macintosh" start="2016-08-23T08:42:55.777Z">
<to secs="0">
<body>asdf</body>
</to>
<to secs="5">
<body>aafs</body>
</to>
<from secs="2" jid="haha#macintosh">
<body>sax</body>
</from>
<set
xmlns="http://jabber.org/protocol/rsm">
<first index="0">0</first>
<last>2</last>
<count>3</count>
</set>
</chat>
</iq>
But when I open the database, ofMessageArchive table, I can see much more messages with group12 (~20 messages) while in the result, I only got 3. May I miss something?
Follow this format, it works for me perfectly,
<iq id='a5sV8-21' type='set'>
<query xmlns='urn:xmpp:mam:0' queryid="12345678">
<x xmlns="jabber:x:data" type="submit">
<field var="FORM_TYPE" type="hidden"><value>urn:xmpp:mam:0</value></field>
<field var="with"><value>id#domain</value></field>
</x>
<set xmlns="http://jabber.org/protocol/rsm">
<max>message_count</max>
</set>
</query>
</iq>
** If xmpp:mam:0 doesn't work use xmpp:mam:1

ejabberd bookmarks replacing previous bookmarks

I'm using ejabberd as a chat server. When I send the request
(example from http://xmpp.org/extensions/xep-0048.html#storage-pubsub-upload)
<iq from='juliet#capulet.lit/balcony' type='set' id='pip1'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<publish node='storage:bookmarks'>
<item id='current'>
<storage xmlns='storage:bookmarks'>
<conference name='The Play&apos;s the Thing'
autojoin='true'
jid='theplay#conference.shakespeare.lit'>
<nick>JC</nick>
</conference>
</storage>
</item>
</publish>
<publish-options>
<x xmlns='jabber:x:data' type='submit'>
<field var='FORM_TYPE' type='hidden'>
<value>http://jabber.org/protocol/pubsub#publish-options</value>
</field>
<field var='pubsub#persist_items'>
<value>true</value>
</field>
<field var='pubsub#access_model'>
<value>whitelist</value>
</field>
</x>
</publish-options>
</pubsub>
</iq>
PubSub configuration:
mod_pubsub:
db_type: odbc
access_createnode: pubsub_createnode
## reduces resource comsumption, but XEP incompliant
ignore_pep_from_offline: true
## XEP compliant, but increases resource comsumption
## ignore_pep_from_offline: false
last_item_cache: false
plugins:
- "flat"
- "hometree"
- "pep" # pep requires mod_caps
It works fine. But if I send a similar request to store a different chat room it replaces this one. Even if I change the item "id". Any ideas on how to store multiple conferences?
The Bookmarks specification is leveraging Personal Eventing Protocol. The assumption we made for PEP in ejabberd with default configuration is the the number of kept items on those special PubSub nodes is '1'.
You can check this by sending the following node configuration request:
<iq type='get'
id='config1'>
<pubsub xmlns='http://jabber.org/protocol/pubsub#owner'>
<configure node='storage:bookmarks'/>
</pubsub>
</iq>
You will see that the reply shows that max number of items is '1':
<iq from="mremond#localhost" type="result" to="mremond#localhost/MacBook-Pro-de-Mickael" id="config1">
<pubsub xmlns="http://jabber.org/protocol/pubsub#owner">
<configure node="storage:bookmarks">
<x xmlns="jabber:x:data" type="form">
...
<field type="text-single" label="Max # of items to persist" var="pubsub#max_items">
<value>1</value>
</field>
...
</x>
</configure>
</pubsub>
</iq>
It means indeed that you are expected to have only one bookmark set. However, it does not prevent you from storing several bookmarks in the same set, as follow:
<iq type='set' id='pip1'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<publish node='storage:bookmarks'>
<item id='current'>
<storage xmlns='storage:bookmarks'>
<conference name='Bookmark1'
autojoin='false'
jid='room1#conference.shakespeare.lit'>
<nick>Mynick1</nick>
</conference>
<conference name='Bookmark2'
autojoin='true'
jid='room2#conference.shakespeare.lit'>
<nick>Mynick2</nick>
</conference>
</storage>
</item>
</publish>
<publish-options>
<x xmlns='jabber:x:data' type='submit'>
<field var='FORM_TYPE' type='hidden'>
<value>http://jabber.org/protocol/pubsub#publish-options</value>
</field>
<field var='pubsub#persist_items'>
<value>true</value>
</field>
<field var='pubsub#access_model'>
<value>whitelist</value>
</field>
</x>
</publish-options>
</pubsub>
</iq>
ejabberd will reply with success:
<iq from="mremond#localhost" type="result" to="mremond#localhost/MacBook-Pro-de-Mickael" id="pip1">
<pubsub xmlns="http://jabber.org/protocol/pubsub">
<publish node="storage:bookmarks">
<item id="current"/>
</publish>
</pubsub>
</iq>
You can then query your bookmark and check that you have two bookmarks in that bookmark set:
<iq type='get' id='retrieve1'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<items node='storage:bookmarks'/>
</pubsub>
</iq>
and response is:
<iq from="mremond#localhost" type="result" to="mremond#localhost/MacBook-Pro-de-Mickael" id="retrieve1">
<pubsub xmlns="http://jabber.org/protocol/pubsub">
<items node="storage:bookmarks">
<item id="current">
<storage xmlns="storage:bookmarks">
<conference name="Bookmark1" autojoin="false" jid="room1#conference.shakespeare.lit">
<nick>Mynick1</nick>
</conference>
<conference name="Bookmark2" autojoin="true" jid="room2#conference.shakespeare.lit">
<nick>Mynick2</nick>
</conference>
</storage>
</item>
</items>
</pubsub>
</iq>
You can store several bookmarks in the same set. Just upload all of them at once. So, to update the bookmark set, you are supposed to read it first and then store the updated version, not send incremental changes.
That said, I read the spec several times (XEP-0048 Bookmarks and XEP-0163 PEP). I do not see example or reference regarding the number of items on a PEP node. All the examples show only one item. The goal of PEP being to broadcast updates of a state. The assumption in most of the specification is that there is only one item involved (One avatar, one geoloc, etc). However, we would be happy to revise our assumption if we can find explicit element in the specification about the number of items that can be used.

Result Set Management for Last Page (Reversed RSM)

I'm now developing an apps with message history retrieval based on XEP-0136 with Openfire Server.
I've read that message history retrieval can be combined with Result Set Management (RSM)-XEP-0059.
We can delimit the number of message retrieval request by setting max attribute of RSM like this:
<iq type='get' id='juliet1'>
<list xmlns='urn:xmpp:archive'
with='juliet#capulet.com'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>5</max>
</set>
</list>
</iq>
This should return the first 5 chat list from the top (ordered by chat time ascending).
My question is how to retrieve the last 5 chat list from the bottom, so I can get the latest chat message not the first time chat.
I've seen this Reversed RSM standard suggestion, like this:
<iq type='get' id='juliet1'>
<list xmlns='urn:xmpp:archive'
with='juliet#capulet.com'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>5</max>
<before />
<reversed />
</set>
</list>
</iq>
But this standard seems not yet implemented.
Thanks in advance
Based on this, the stanza is like this:
<iq type='get' id='juliet1'>
<list xmlns='urn:xmpp:archive'
with='juliet#capulet.com'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>5</max>
<before />
</set>
</list>
</iq>
You can retrieve the collection from bottom by RSM.
But seems Openfire message archiving plugin had some bugs with this RSM.
Reference: http://community.igniterealtime.org/message/230389#230389
So, the possible solution is getting count of my collection:
<iq type='get' id='juliet1'>
<list xmlns='urn:xmpp:archive'
with='juliet#capulet.com'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>0</max>
</set>
</list>
</iq>
It will return:
<iq xmlns='jabber:client' type='result' id='juliet1' to='admin#somehost'>
<list xmlns='urn:xmpp:archive'>
<set xmlns='http://jabber.org/protocol/rsm'>
<count>10</count>
</set>
</list>
</iq>
And I select the collection by index:
<iq type='get' id='juliet1'>
<list xmlns='urn:xmpp:archive'
with='juliet#capulet.com'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>5</max>
<index>4</index>
</set>
</list>
</iq>

Get members nickname of MUC Room

Is there a way to get all nicknames of a MUC Room with an ejabberd server?
I'm trying with:
<iq from='crone1#shakespeare.lit/desktop'
id='member3'
to='coven#chat.shakespeare.lit'
type='get'>
<query xmlns='http://jabber.org/protocol/muc#admin'>
<item affiliation='member'/>
</query>
</iq>
but I obtain only jid without nicknames:
<iq from='coven#chat.shakespeare.lit'
id='member3'
to='crone1#shakespeare.lit/desktop'
type='result'>
<query xmlns='http://jabber.org/protocol/muc#admin'>
<item affiliation='member'
jid='hag66#shakespeare.lit'
role='participant'/>
</query>
</iq>
On 6.5 Querying for Room Items from XEP 0045 when you send
<iq from='$user-name#$user-server/$user-resorce'
id='someid'
to='$chat-room-to-query#$chatserver'
type='get'>
<query xmlns='http://jabber.org/protocol/disco#items'/>
</iq>
You have the following description
An implementation MAY return a list of existing occupants if that information is publicly available, or return no list at all if this information is kept private.(emphasis mine)
if the room is public them you get
<iq from='$chat-room-to-query#$chatserver'
id='someid'
to='$user-name#$user-server/$user-resorce'
type='result'>
<query xmlns='http://jabber.org/protocol/disco#items'>
<item jid='$chat-room-to-query#$chatserver/$firstnick'/>
<item jid='$chat-room-to-query#$chatserver/$secondnick'/>
<...>
</query>
</iq>
From my knowledge ejabberd implements this correctly.
