XEP-0421: Anonymous unique occupant identifiers for MUCs

Stanza elements#

class slixmpp.plugins.xep_0421.stanza.OccupantId(xml=None, parent=None)[source]#

An Occupant-id tag.

An <occupant-id/> tag is set by the MUC.

This is useful in semi-anon MUCs (and MUC-PMs) as a stable identifier to prevent the usual races with nicknames.

Without occupant-id, getting the following messages from MUC history would prevent a client from asserting senders are the same entity:

<message type='groupchat' from='foo@muc/nick1' id='message1'>
    <body>Some message</body>
    <occupant-id xmlns='urn:xmpp:occupant-id:0' id='unique-opaque-id1'/>
<message type='groupchat' from='foo@muc/nick2' id='message2'>
    <body>Some correction</body>
    <occupant-id xmlns='urn:xmpp:occupant-id:0' id='unique-opaque-id1'/>
    <replace xmlns='urn:xmpp:message-correct:0' id='message1'/>
interface = {'id'}#
iterables: List[ElementBase]#

A list of child stanzas whose class is included in plugin_iterables.

loaded_plugins: Set[str]#
name: ClassVar[str] = 'occupant-id'#

The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'urn:xmpp:occupant-id:0'#

The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

parent: Optional[ReferenceType[ElementBase]]#

A weakref.weakref to the parent stanza, if there is one. If not, then parent is None.

plugin_attrib: ClassVar[str] = 'occupant-id'#

For ElementBase subclasses which are intended to be used as plugins, the plugin_attrib value defines the plugin name. Plugins may be accessed by using the plugin_attrib value as the interface. An example using plugin_attrib = 'foo':

register_stanza_plugin(Message, FooPlugin)
msg = Message()
plugins: Dict[Tuple[str, Optional[str]], ElementBase]#

An ordered dictionary of plugin stanzas, mapped by their plugin_attrib value.

tag: str#

The name of the tag for the stanza’s root element. It is the same as calling tag_name() and is formatted as '{namespace}elementname'.

xml: ET.Element#

The underlying XML object for the stanza. It is a standard xml.etree.ElementTree object.
