.. index:: XMLStream, BaseXMPP, ClientXMPP, ComponentXMPP
SleekXMPP Architecture
======================
The core of SleekXMPP is contained in four classes: ``XMLStream``,
``BaseXMPP``, ``ClientXMPP``, and ``ComponentXMPP``. Along side this
stack is a library for working with XML objects that eliminates most
of the tedium of creating/manipulating XML.
.. image:: _static/images/arch_layers.png
:height: 300px
:align: center
.. index:: XMLStream
The Foundation: XMLStream
-------------------------
``XMLStream`` is a mostly XMPP-agnostic class whose purpose is to read
and write from a bi-directional XML stream. It also allows for callback
functions to execute when XML matching given patterns is received; these
callbacks are also referred to as :term:`stream handlers <stream handler>`.
The class also provides a basic eventing system which can be triggered
either manually or on a timed schedule.
The Main Threads
~~~~~~~~~~~~~~~~
``XMLStream`` instances run using at least three background threads: the
send thread, the read thread, and the scheduler thread. The send thread is
in charge of monitoring the send queue and writing text to the outgoing
XML stream. The read thread pulls text off of the incoming XML stream and
stores the results in an event queue. The scheduler thread is used to emit
events after a given period of time.
Additionally, the main event processing loop may be executed in its
own thread if SleekXMPP is being used in the background for another
application.
Short-lived threads may also be spawned as requested for threaded
:term:`event handlers <event handler>`.
How XML Text is Turned into Action
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To demonstrate the flow of information, let's consider what happens
when this bit of XML is received (with an assumed namespace of
``jabber:client``):
.. code-block:: xml
<message to="user@example.com" from="friend@example.net">
<body>Hej!</body>
</message>
1. **Convert XML strings into objects.**
Incoming text is parsed and converted into XML objects (using
ElementTree) which are then wrapped into what are referred to as
:term:`Stanza objects <stanza object>`. The appropriate class for the
new object is determined using a map of namespaced element names to
classes.
Our incoming XML is thus turned into a ``Message`` :term:`stanza object`
because the namespaced element name ``{jabber:client}message`` is
associated with the class ``sleekxmpp.stanza.Message``.
2. **Match stanza objects to callbacks.**
These objects are then compared against the stored patterns associated
with the registered callback handlers. For each match, a copy of the
:term:`stanza object` is paired with a reference to the handler and
placed into the event queue.
Our ``Message`` object is thus paired with the message stanza handler
``BaseXMPP._handle_message`` to create the tuple::
('stanza', stanza_obj, handler)
3. **Process the event queue.**
The event queue is the heart of SleekXMPP. Nearly every action that
takes place is first inserted into this queue, whether that be received
stanzas, custom events, or scheduled events.
When the stanza is pulled out of the event queue with an associated
callback, the callback function is executed with the stanza as its only
parameter.
.. warning::
The callback, aka :term:`stream handler`, is executed in the main
processing thread. If the handler blocks, event processing will also
block.
4. **Raise Custom Events**
Since a :term:`stream handler` shouldn't block, if extensive processing
for a stanza is required (such as needing to send and receive an
``Iq`` stanza), then custom events must be used. These events are not
explicitly tied to the incoming XML stream and may be raised at any
time. Importantly, these events may be handled in their own thread.
When the event is raised, a copy of the stanza is created for each
handler registered for the event. In contrast to :term:`stream handlers <stream handler>`,
these functions are referred to as :term:`event handlers <event handler>`.
Each stanza/handler pair is then put into the event queue.
.. note::
It is possible to skip the event queue and process an event immediately
by using ``direct=True`` when raising the event.
The code for ``BaseXMPP._handle_message`` follows this pattern, and
raises a ``'message'`` event::
self.event('message', msg)
The event call then places the message object back into the event queue
paired with an :term:`event handler`::
('event', 'message', msg_copy1, custom_event_handler_1)
('event', 'message', msg_copy2, custom_evetn_handler_2)
5. **Process Custom Events**
The stanza and :term:`event handler` are then pulled from the event
queue, and the handler is executed, passing the stanza as its only
argument. If the handler was registered as threaded, then a new thread
will be spawned for it.
.. note::
Events may be raised without needing :term:`stanza objects <stanza object>`.
For example, you could use ``self.event('custom', {'a': 'b'})``.
You don't even need any arguments: ``self.event('no_parameters')``.
However, every event handler MUST accept at least one argument.
Finally, after a long trek, our message is handed off to the user's
custom handler in order to do awesome stuff::
msg.reply()
msg['body'] = "Hey! This is awesome!"
msg.send()
.. index:: BaseXMPP, XMLStream
Raising XMPP Awareness: BaseXMPP
--------------------------------
While ``XMLStream`` attempts to shy away from anything too XMPP specific,
``BaseXMPP``'s sole purpose is to provide foundational support for sending
and receiving XMPP stanzas. This support includes registering the basic
message, presence, and iq stanzas, methods for creating and sending
stanzas, and default handlers for incoming messages and keeping track of
presence notifications.
The plugin system for adding new XEP support is also maintained by
``BaseXMPP``.
.. index:: ClientXMPP, BaseXMPP
ClientXMPP
----------
``ClientXMPP`` extends ``BaseXMPP`` with additional logic for connecting to
an XMPP server by performing DNS lookups. It also adds support for stream
features such as STARTTLS and SASL.
.. index:: ComponentXMPP, BaseXMPP
ComponentXMPP
-------------
``ComponentXMPP`` is only a thin layer on top of ``BaseXMPP`` that
implements the component handshake protocol.
.. index::
double: object; stanza
Stanza Objects: A Brief Look
----------------------------
.. seealso::
See :ref:`api-stanza-objects` for a more detailed overview.
Almost worthy of their own standalone library, :term:`stanza objects <stanza object>`
are wrappers for XML objects which expose dictionary like interfaces
for manipulating their XML content. For example, consider the XML:
.. code-block:: xml
<message />
A very plain element to start with, but we can create a :term:`stanza object`
using ``sleekxmpp.stanza.Message`` as so::
msg = Message(xml=ET.fromstring("<message />"))
The ``Message`` stanza class defines interfaces such as ``'body'`` and
``'to'``, so we can assign values to those interfaces to include new XML
content::
msg['body'] = "Following so far?"
msg['to'] = 'user@example.com'
Dumping the XML content of ``msg`` (using ``msg.xml``), we find:
.. code-block:: xml
<message to="user@example.com">
<body>Following so far?</body>
</message>
The process is similar for reading from interfaces and deleting interface
contents. A :term:`stanza object` behaves very similarly to a regular
``dict`` object: you may assign to keys, read from keys, and ``del`` keys.
Stanza interfaces come with built-in behaviours such as adding/removing
attribute and sub element values. However, a lot of the time more custom
logic is needed. This can be provided by defining methods of the form
``get_*``, ``set_*``, and ``del_*`` for any interface which requires custom
behaviour.
Stanza Plugins
~~~~~~~~~~~~~~
Since it is generally possible to embed one XML element inside another,
:term:`stanza objects <stanza object>` may be nested. Nested
:term:`stanza objects <stanza object>` are referred to as :term:`stanza plugins <stanza plugin>`
or :term:`substanzas <substanza>`.
A :term:`stanza plugin` exposes its own interfaces by adding a new
interface to its parent stanza. To demonstrate, consider these two stanza
class definitions using ``sleekxmpp.xmlstream.ElementBase``:
.. code-block:: python
class Parent(ElementBase):
name = "the-parent-xml-element-name"
namespace = "the-parent-namespace"
interfaces = set(('foo', 'bar'))
class Child(ElementBase):
name = "the-child-xml-element-name"
namespace = "the-child-namespace"
plugin_attrib = 'child'
interfaces = set(('baz',))
If we register the ``Child`` stanza as a plugin of the ``Parent`` stanza as
so, using ``sleekxmpp.xmlstream.register_stanza_plugin``::
register_stanza_plugin(Parent, Child)
Then we can access content in the child stanza through the parent.
Note that the interface used to access the child stanza is the same as
``Child.plugin_attrib``::
parent = Parent()
parent['foo'] = 'a'
parent['child']['baz'] = 'b'
The above code would produce:
.. code-block:: xml
<the-parent-xml-element xmlns="the-parent-namespace" foo="a">
<the-child-xml-element xmlsn="the-child-namespace" baz="b" />
</the-parent-xml-element>
It is also possible to allow a :term:`substanza` to appear multiple times
by using ``iterable=True`` in the ``register_stanza_plugin`` call. All
iterable :term:`substanzas <substanza>` can be accessed using a standard
``substanzas`` interface.

Creating a SleekXMPP Plugin
===========================
One of the goals of SleekXMPP is to provide support for every draft or final
XMPP extension (`XEP <http://xmpp.org/extensions/>`_). To do this, SleekXMPP has a
plugin mechanism for adding the functionalities required by each XEP. But even
though plugins were made to quickly implement and prototype the official XMPP
extensions, there is no reason you can't create your own plugin to implement
your own custom XMPP-based protocol.
This guide will help walk you through the steps to
implement a rudimentary version of `XEP-0077 In-band
Registration <http://xmpp.org/extensions/xep-0077.html>`_. In-band registration
was implemented in example 14-6 (page 223) of `XMPP: The Definitive
Guide <http://oreilly.com/catalog/9780596521271>`_ because there was no SleekXMPP
plugin for XEP-0077 at the time of writing. We will partially fix that issue
here by turning the example implementation from *XMPP: The Definitive Guide*
into a plugin. Again, note that this will not a complete implementation, and a
different, more robust, official plugin for XEP-0077 may be added to SleekXMPP
in the future.
.. note::
The example plugin created in this guide is for the server side of the
registration process only. It will **NOT** be able to register new accounts
on an XMPP server.
First Steps
-----------
Every plugin inherits from the class :mod:`base_plugin <sleekxmpp.plugins.base.base_plugin>`,
and must include a ``plugin_init`` method. While the
plugins distributed with SleekXMPP must be placed in the plugins directory
``sleekxmpp/plugins`` to be loaded, custom plugins may be loaded from any
module. To do so, use the following form when registering the plugin:
.. code-block:: python
self.register_plugin('myplugin', module=mod_containing_my_plugin)
The plugin name must be the same as the plugin's class name.
Now, we can open our favorite text editors and create ``xep_0077.py`` in
``SleekXMPP/sleekxmpp/plugins``. We want to do some basic house-keeping and
declare the name and description of the XEP we are implementing. If you
are creating your own custom plugin, you don't need to include the ``xep``
attribute.
.. code-block:: python
"""
Creating a SleekXMPP Plugin
This is a minimal implementation of XEP-0077 to serve
as a tutorial for creating SleekXMPP plugins.
"""
from sleekxmpp.plugins.base import base_plugin
class xep_0077(base_plugin):
"""
XEP-0077 In-Band Registration
"""
def plugin_init(self):
self.description = "In-Band Registration"
self.xep = "0077"
Now that we have a basic plugin, we need to edit
``sleekxmpp/plugins/__init__.py`` to include our new plugin by adding
``'xep_0077'`` to the ``__all__`` declaration.
Interacting with Other Plugins
------------------------------
In-band registration is a feature that should be advertised through `Service
Discovery <http://xmpp.org/extensions/xep-0030.html>`_. To do that, we tell the
``xep_0030`` plugin to add the ``"jabber:iq:register"`` feature. We put this
call in a method named ``post_init`` which will be called once the plugin has
been loaded; by doing so we advertise that we can do registrations only after we
finish activating the plugin.
The ``post_init`` method needs to call ``base_plugin.post_init(self)``
which will mark that ``post_init`` has been called for the plugin. Once the
SleekXMPP object begins processing, ``post_init`` will be called on any plugins
that have not already run ``post_init``. This allows you to register plugins and
their dependencies without needing to worry about the order in which you do so.
**Note:** by adding this call we have introduced a dependency on the XEP-0030
plugin. Be sure to register ``'xep_0030'`` as well as ``'xep_0077'``. SleekXMPP
does not automatically load plugin dependencies for you.
.. code-block:: python
def post_init(self):
base_plugin.post_init(self)
self.xmpp['xep_0030'].add_feature("jabber:iq:register")
Creating Custom Stanza Objects
------------------------------
Now, the IQ stanzas needed to implement our version of XEP-0077 are not very
complex, and we could just interact with the XML objects directly just like
in the *XMPP: The Definitive Guide* example. However, creating custom stanza
objects is good practice.
We will create a new ``Registration`` stanza. Following the *XMPP: The
Definitive Guide* example, we will add support for a username and password
field. We also need two flags: ``registered`` and ``remove``. The ``registered``
flag is sent when an already registered user attempts to register, along with
their registration data. The ``remove`` flag is a request to unregister a user's
account.
Adding additional `fields specified in
XEP-0077 <http://xmpp.org/extensions/xep-0077.html#registrar-formtypes-register>`_
will not be difficult and is left as an exercise for the reader.
Our ``Registration`` class needs to start with a few descriptions of its
behaviour:
* ``namespace``
The namespace our stanza object lives in. In this case,
``"jabber:iq:register"``.
* ``name``
The name of the root XML element. In this case, the ``query`` element.
* ``plugin_attrib``
The name to access this type of stanza. In particular, given a
registration stanza, the ``Registration`` object can be found using:
``iq_object['register']``.
* ``interfaces``
A list of dictionary-like keys that can be used with the stanza object.
When using ``"key"``, if there exists a method of the form ``getKey``,
``setKey``, or``delKey`` (depending on context) then the result of calling
that method will be returned. Otherwise, the value of the attribute ``key``
of the main stanza element is returned if one exists.
**Note:** The accessor methods currently use title case, and not camel case.
Thus if you need to access an item named ``"methodName"`` you will need to
use ``getMethodname``. This naming convention might change to full camel
case in a future version of SleekXMPP.
* ``sub_interfaces``
A subset of ``interfaces``, but these keys map to the text of any
subelements that are direct children of the main stanza element. Thus,
referencing ``iq_object['register']['username']`` will either execute
``getUsername`` or return the value in the ``username`` element of the
query.
If you need to access an element, say ``elem``, that is not a direct child
of the main stanza element, you will need to add ``getElem``, ``setElem``,
and ``delElem``. See the note above about naming conventions.
.. code-block:: python
from sleekxmpp.xmlstream import ElementBase, ET, JID, register_stanza_plugin
from sleekxmpp import Iq
class Registration(ElementBase):
namespace = 'jabber:iq:register'
name = 'query'
plugin_attrib = 'register'
interfaces = set(('username', 'password', 'registered', 'remove'))
sub_interfaces = interfaces
def getRegistered(self):
present = self.xml.find('{%s}registered' % self.namespace)
return present is not None
def getRemove(self):
present = self.xml.find('{%s}remove' % self.namespace)
return present is not None
def setRegistered(self, registered):
if registered:
self.addField('registered')
else:
del self['registered']
def setRemove(self, remove):
if remove:
self.addField('remove')
else:
del self['remove']
def addField(self, name):
itemXML = ET.Element('{%s}%s' % (self.namespace, name))
self.xml.append(itemXML)
Setting a ``sub_interface`` attribute to ``""`` will remove that subelement.
Since we want to include empty registration fields in our form, we need the
``addField`` method to add the empty elements.
Since the ``registered`` and ``remove`` elements are just flags, we need to add
custom logic to enforce the binary behavior.
Extracting Stanzas from the XML Stream
--------------------------------------
Now that we have a custom stanza object, we need to be able to detect when we
receive one. To do this, we register a stream handler that will pattern match
stanzas off of the XML stream against our stanza object's element name and
namespace. To do so, we need to create a ``Callback`` object which contains
an XML fragment that can identify our stanza type. We can add this handler
registration to our ``plugin_init`` method.
Also, we need to associate our ``Registration`` class with IQ stanzas;
that requires the use of the ``register_stanza_plugin`` function (in
``sleekxmpp.xmlstream.stanzabase``) which takes the class of a parent stanza
type followed by the substanza type. In our case, the parent stanza is an IQ
stanza, and the substanza is our registration query.
The ``__handleRegistration`` method referenced in the callback will be our
handler function to process registration requests.
.. code-block:: python
def plugin_init(self):
self.description = "In-Band Registration"
self.xep = "0077"
self.xmpp.registerHandler(
Callback('In-Band Registration',
MatchXPath('{%s}iq/{jabber:iq:register}query' % self.xmpp.default_ns),
self.__handleRegistration))
register_stanza_plugin(Iq, Registration)
Handling Incoming Stanzas and Triggering Events
-----------------------------------------------
There are six situations that we need to handle to finish our implementation of
XEP-0077.
**Registration Form Request from a New User:**
.. code-block:: xml
<iq type="result">
<query xmlns="jabber:iq:register">
<username />
<password />
</query>
</iq>
**Registration Form Request from an Existing User:**
.. code-block:: xml
<iq type="result">
<query xmlns="jabber:iq:register">
<registered />
<username>Foo</username>
<password>hunter2</password>
</query>
</iq>
**Unregister Account:**
.. code-block:: xml
<iq type="result">
<query xmlns="jabber:iq:register" />
</iq>
**Incomplete Registration:**
.. code-block:: xml
<iq type="error">
<query xmlns="jabber:iq:register">
<username>Foo</username>
</query>
<error code="406" type="modify">
<not-acceptable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
</error>
</iq>
**Conflicting Registrations:**
.. code-block:: xml
<iq type="error">
<query xmlns="jabber:iq:register">
<username>Foo</username>
<password>hunter2</password>
</query>
<error code="409" type="cancel">
<conflict xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
</error>
</iq>
**Successful Registration:**
.. code-block:: xml
<iq type="result">
<query xmlns="jabber:iq:register" />
</iq>
Cases 1 and 2: Registration Requests
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Responding to registration requests depends on if the requesting user already
has an account. If there is an account, the response should include the
``registered`` flag and the user's current registration information. Otherwise,
we just send the fields for our registration form.
We will handle both cases by creating a ``sendRegistrationForm`` method that
will create either an empty of full form depending on if we provide it with
user data. Since we need to know which form fields to include (especially if we
add support for the other fields specified in XEP-0077), we will also create a
method ``setForm`` which will take the names of the fields we wish to include.
.. code-block:: python
def plugin_init(self):
self.description = "In-Band Registration"
self.xep = "0077"
self.form_fields = ('username', 'password')
... remainder of plugin_init
...
def __handleRegistration(self, iq):
if iq['type'] == 'get':
# Registration form requested
userData = self.backend[iq['from'].bare]
self.sendRegistrationForm(iq, userData)
def setForm(self, *fields):
self.form_fields = fields
def sendRegistrationForm(self, iq, userData=None):
reg = iq['register']
if userData is None:
userData = {}
else:
reg['registered'] = True
for field in self.form_fields:
data = userData.get(field, '')
if data:
# Add field with existing data
reg[field] = data
else:
# Add a blank field
reg.addField(field)
iq.reply().setPayload(reg.xml)
iq.send()
Note how we are able to access our ``Registration`` stanza object with
``iq['register']``.
A User Backend
++++++++++++++
You might have noticed the reference to ``self.backend``, which is an object
that abstracts away storing and retrieving user information. Since it is not
much more than a dictionary, we will leave the implementation details to the
final, full source code example.
Case 3: Unregister an Account
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The next simplest case to consider is responding to a request to remove
an account. If we receive a ``remove`` flag, we instruct the backend to
remove the user's account. Since your application may need to know about
when users are registered or unregistered, we trigger an event using
``self.xmpp.event('unregister_user', iq)``. See the component examples below for
how to respond to that event.
.. code-block:: python
def __handleRegistration(self, iq):
if iq['type'] == 'get':
# Registration form requested
userData = self.backend[iq['from'].bare]
self.sendRegistrationForm(iq, userData)
elif iq['type'] == 'set':
# Remove an account
if iq['register']['remove']:
self.backend.unregister(iq['from'].bare)
self.xmpp.event('unregistered_user', iq)
iq.reply().send()
return
Case 4: Incomplete Registration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For the next case we need to check the user's registration to ensure it has all
of the fields we wanted. The simple option that we will use is to loop over the
field names and check each one; however, this means that all fields we send to
the user are required. Adding optional fields is left to the reader.
Since we have received an incomplete form, we need to send an error message back
to the user. We have to send a few different types of errors, so we will also
create a ``_sendError`` method that will add the appropriate ``error`` element
to the IQ reply.
.. code-block:: python
def __handleRegistration(self, iq):
if iq['type'] == 'get':
# Registration form requested
userData = self.backend[iq['from'].bare]
self.sendRegistrationForm(iq, userData)
elif iq['type'] == 'set':
if iq['register']['remove']:
# Remove an account
self.backend.unregister(iq['from'].bare)
self.xmpp.event('unregistered_user', iq)
iq.reply().send()
return
for field in self.form_fields:
if not iq['register'][field]:
# Incomplete Registration
self._sendError(iq, '406', 'modify', 'not-acceptable'
"Please fill in all fields.")
return
...
def _sendError(self, iq, code, error_type, name, text=''):
iq.reply().setPayload(iq['register'].xml)
iq.error()
iq['error']['code'] = code
iq['error']['type'] = error_type
iq['error']['condition'] = name
iq['error']['text'] = text
iq.send()
Cases 5 and 6: Conflicting and Successful Registration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We are down to the final decision on if we have a successful registration. We
send the user's data to the backend with the ``self.backend.register`` method.
If it returns ``True``, then registration has been successful. Otherwise,
there has been a conflict with usernames and registration has failed. Like
with unregistering an account, we trigger an event indicating that a user has
been registered by using ``self.xmpp.event('registered_user', iq)``. See the
component examples below for how to respond to this event.
.. code-block:: python
def __handleRegistration(self, iq):
if iq['type'] == 'get':
# Registration form requested
userData = self.backend[iq['from'].bare]
self.sendRegistrationForm(iq, userData)
elif iq['type'] == 'set':
if iq['register']['remove']:
# Remove an account
self.backend.unregister(iq['from'].bare)
self.xmpp.event('unregistered_user', iq)
iq.reply().send()
return
for field in self.form_fields:
if not iq['register'][field]:
# Incomplete Registration
self._sendError(iq, '406', 'modify', 'not-acceptable',
"Please fill in all fields.")
return
if self.backend.register(iq['from'].bare, iq['register']):
# Successful registration
self.xmpp.event('registered_user', iq)
iq.reply().setPayload(iq['register'].xml)
iq.send()
else:
# Conflicting registration
self._sendError(iq, '409', 'cancel', 'conflict',
"That username is already taken.")
Example Component Using the XEP-0077 Plugin
-------------------------------------------
Alright, the moment we've been working towards - actually using our plugin to
simplify our other applications. Here is a basic component that simply manages
user registrations and sends the user a welcoming message when they register,
and a farewell message when they delete their account.
Note that we have to register the ``'xep_0030'`` plugin first,
and that we specified the form fields we wish to use with
``self.xmpp.plugin['xep_0077'].setForm('username', 'password')``.
.. code-block:: python
import sleekxmpp.componentxmpp
class Example(sleekxmpp.componentxmpp.ComponentXMPP):
def __init__(self, jid, password):
sleekxmpp.componentxmpp.ComponentXMPP.__init__(self, jid, password, 'localhost', 8888)
self.registerPlugin('xep_0030')
self.registerPlugin('xep_0077')
self.plugin['xep_0077'].setForm('username', 'password')
self.add_event_handler("registered_user", self.reg)
self.add_event_handler("unregistered_user", self.unreg)
def reg(self, iq):
msg = "Welcome! %s" % iq['register']['username']
self.sendMessage(iq['from'], msg, mfrom=self.fulljid)
def unreg(self, iq):
msg = "Bye! %s" % iq['register']['username']
self.sendMessage(iq['from'], msg, mfrom=self.fulljid)
**Congratulations!** We now have a basic, functioning implementation of
XEP-0077.

stream handler
A callback function that accepts stanza objects pulled directly
from the XML stream. A stream handler is encapsulated in a
object that includes a :term:`Matcher` object, and which provides
additional semantics. For example, the ``Waiter`` handler wrapper
blocks thread execution until a matching stanza is received.
event handler
A callback function that responds to events raised by
``XMLStream.event``. An event handler may be marked as
threaded, allowing it to execute outside of the main processing
loop.
stanza object
Informally may refer both to classes which extend ``ElementBase``
or ``StanzaBase``, and to objects of such classes.
A stanza object is a wrapper for an XML object which exposes ``dict``
like interfaces which may be assigned to, read from, or deleted.
stanza plugin
A :term:`stanza object` which has been registered as a potential child
of another stanza object. The plugin stanza may accessed through the
parent stanza using the plugin's ``plugin_attrib`` as an interface.

XEP-0030: Working with Service Discovery
========================================
XMPP networks can be composed of many individual clients, components,
and servers. Determining the JIDs for these entities and the various
features they may support is the role of `XEP-0030, Service
Discovery <http://xmpp.org/extensions/xep-0030.html>`_, or "disco" for short.
Every XMPP entity may possess what are called nodes. A node is just a name for
some aspect of an XMPP entity. For example, if an XMPP entity provides `Ad-Hoc
Commands <http://xmpp.org/extensions/xep-0050.html>`_, then it will have a node
named ``http://jabber.org/protocol/commands`` which will contain information
about the commands provided. Other agents using these ad-hoc commands will
interact with the information provided by this node. Note that the node name is
just an identifier; there is no inherent meaning.
Working with service discovery is about creating and querying these nodes.
According to XEP-0030, a node may contain three types of information:
identities, features, and items. (Further, extensible, information types are
defined in `XEP-0128 <http://xmpp.org/extensions/xep-0128.html>`_, but they are
not yet implemented by SleekXMPP.) SleekXMPP provides methods to configure each
of these node attributes.
Configuring Service Discovery
-----------------------------
The design focus for the XEP-0030 plug-in is handling info and items requests
in a dynamic fashion, allowing for complex policy decisions of who may receive
information and how much, or use alternate backend storage mechanisms for all
of the disco data. To do this, each action that the XEP-0030 plug-in performs
is handed off to what is called a "node handler," which is just a callback
function. These handlers are arranged in a hierarchy that allows for a single
handler to manage an entire domain of JIDs (say for a component), while allowing
other handler functions to override that global behaviour for certain JIDs, or
even further limited to only certain JID and node combinations.
The Dynamic Handler Hierarchy
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* ``global``: (JID is None, node is None)
Handlers assigned at this level for an action (such as ``add_feature``) provide a global default
behaviour when the action is performed.
* ``jid``: (JID assigned, node is None)
At this level, handlers provide a default behaviour for actions affecting any node owned by the
JID in question. This level is most useful for component connections; there is effectively no
difference between this and the global level when using a client connection.
* ``node``: (JID assigned, node assigned)
A handler for this level is responsible for carrying out an action for only one node, and is the
most specific handler type available. These types of handlers will be most useful for "special"
nodes that require special processing different than others provided by the JID, such as using
access control lists, or consolidating data from other nodes.
Default Static Handlers
~~~~~~~~~~~~~~~~~~~~~~~
The XEP-0030 plug-in provides a default set of handlers that work using in-memory
disco stanzas. Each handler simply performs the appropriate lookup or storage
operation using these stanzas without doing any complex operations such as
checking an ACL, etc.
You may find it necessary at some point to revert a particular node or JID to
using the default, static handlers. To do so, use the method ``make_static()``.
You may also elect to only convert a given set of actions instead.
Creating a Node Handler
~~~~~~~~~~~~~~~~~~~~~~~
Every node handler receives three arguments: the JID, the node, and a data
parameter that will contain the relevant information for carrying out the
handler's action, typically a dictionary.
The JID will always have a value, defaulting to ``xmpp.boundjid.full`` for
components or ``xmpp.boundjid.bare`` for clients. The node value may be None or
a string.
Only handlers for the actions ``get_info`` and ``get_items`` need to have return
values. For these actions, DiscoInfo or DiscoItems stanzas are exepected as
output. It is also acceptable for handlers for these actions to generate an
XMPPError exception when necessary.
Example Node Handler:
+++++++++++++++++++++
Here is one of the built-in default handlers as an example:
.. code-block:: python
def add_identity(self, jid, node, data):
"""
Add a new identity to the JID/node combination.
The data parameter may provide:
category -- The general category to which the agent belongs.
itype -- A more specific designation with the category.
name -- Optional human readable name for this identity.
lang -- Optional standard xml:lang value.
"""
self.add_node(jid, node)
self.nodes[(jid, node)]['info'].add_identity(
data.get('category', ''),
data.get('itype', ''),
data.get('name', None),
data.get('lang', None))
Adding Identities, Features, and Items
--------------------------------------
In order to maintain some backwards compatibility, the methods ``add_identity``,
``add_feature``, and ``add_item`` do not follow the method signature pattern of
the other API methods (i.e. jid, node, then other options), but rather retain
the parameter orders from previous plug-in versions.
Adding an Identity
~~~~~~~~~~~~~~~~~~
Adding an identity may be done using either the older positional notation, or
with keyword parameters. The example below uses the keyword arguments, but in
the same order as expected using positional arguments.
.. code-block:: python
xmpp['xep_0030'].add_identity(category='client',
itype='bot',
name='Sleek',
node='foo',
jid=xmpp.boundjid.full,
lang='no')
The JID and node values determine which handler will be used to perform the
``add_identity`` action.
The ``lang`` parameter allows for adding localized versions of identities using
the ``xml:lang`` attribute.
Adding a Feature
~~~~~~~~~~~~~~~~
The position ordering for ``add_feature()`` is to include the feature, then
specify the node and then the JID. The JID and node values determine which
handler will be used to perform the ``add_feature`` action.
.. code-block:: python
xmpp['xep_0030'].add_feature(feature='jabber:x:data',
node='foo',
jid=xmpp.boundjid.full)
Adding an Item
~~~~~~~~~~~~~~
The parameters to ``add_item()`` are potentially confusing due to the fact that
adding an item requires two JID and node combinations: the JID and node of the
item itself, and the JID and node that will own the item.
.. code-block:: python
xmpp['xep_0030'].add_item(jid='myitemjid@example.com',
name='An Item!',
node='owner_node',
subnode='item_node',
ijid=xmpp.boundjid.full)
.. note::
In this case, the owning JID and node are provided with the
parameters ``ijid`` and ``node``.
Peforming Disco Queries
-----------------------
The methods ``get_info()`` and ``get_items()`` are used to query remote JIDs
and their nodes for disco information. Since these methods are wrappers for
sending Iq stanzas, they also accept all of the parameters of the ``Iq.send()``
method. The ``get_items()`` method may also accept the boolean parameter
``iterator``, which when set to ``True`` will return an iterator object using
the `XEP-0059 <http://xmpp.org/extensions/xep-0059.html>`_ plug-in.
.. code-block:: python
info = self['xep_0030'].get_info(jid='foo@example.com',
node='bar',
ifrom='baz@mycomponent.example.com',
block=True,
timeout=30)
items = self['xep_0030'].get_info(jid='foo@example.com',
node='bar',
iterator=True)
For more examples on how to use basic disco queries, check the ``disco_browser.py``
example in the ``examples`` directory.
Local Queries
~~~~~~~~~~~~~
In some cases, it may be necessary to query the contents of a node owned by the
client itself, or one of a component's many JIDs. The same method is used as for
normal queries, with two differences. First, the parameter ``local=True`` must
be used. Second, the return value will be a DiscoInfo or DiscoItems stanza, not
a full Iq stanza.
.. code-block:: python
info = self['xep_0030'].get_info(node='foo', local=True)
items = self['xep_0030'].get_items(jid='somejid@mycomponent.example.com',
node='bar',
local=True)

SleekXMPP is an :ref:`MIT licensed <license>` XMPP library for Python 2.6/3.1+,
and is featured in examples in
`XMPP: The Definitive Guide <http://oreilly.com/catalog/9780596521271>`_
by Kevin Smith, Remko Tronçon, and Peter Saint-Andre. If you've arrived
here from reading the Definitive Guide, please see the notes on updating
the examples to the latest version of SleekXMPP.
SleekXMPP's design goals and philosphy are:
**Low number of dependencies**
Installing and using SleekXMPP should be as simple as possible, without
having to deal with long dependency chains.
As part of reducing the number of dependencies, some third party
modules are included with SleekXMPP in the ``thirdparty`` directory.
Imports from this module first try to import an existing installed
version before loading the packaged version, when possible.
**Every XEP as a plugin**
Following Python's "batteries included" approach, the goal is to
provide support for all currently active XEPs (final and draft). Since
adding XEP support is done through easy to create plugins, the hope is
to also provide a solid base for implementing and creating experimental
XEPs.
**Rewarding to work with**
As much as possible, SleekXMPP should allow things to "just work" using
sensible defaults and appropriate abstractions. XML can be ugly to work
with, but it doesn't have to be that way.

SleekXMPP Quickstart
====================
.. note::
If you have any issues working through this quickstart guide
or the other tutorials here, please either send a message to the
`mailing list <http://groups.google.com/group/sleekxmpp-discussion>`_
or join the chat room at `sleek@conference.jabber.org
<xmpp:sleek@conference.jabber.org?join>`_.
If you have not yet installed SleekXMPP, do so now by either checking out a version
from `Github <http://github.com/fritzy/SleekXMPP>`_, or installing it using ``pip``
or ``easy_install``.
.. code-block:: sh
pip install sleekxmpp # Or: easy_install sleekxmpp
As a basic starting project, we will create an echo bot which will reply to any
messages sent to it. We also go through adding some basic command line configuration
for enabling or disabling debug log outputs and setting the username and password
for the bot.
For the command line options processing, we will use the built-in ``optparse``
module and the ``getpass`` module for reading in passwords.
TL;DR Just Give me the Boilerplate
----------------------------------
As you wish: :ref:`the completed example <echobot_complete>`.
Overview
--------
To get started, here is a brief outline of the structure that the final project will have:
.. code-block:: python
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import logging
import getpass
from optparse import OptionParser
import sleekxmpp
'''Here we will create out echo bot class'''
if __name__ == '__main__':
'''Here we will configure and read command line options'''
'''Here we will instantiate our echo bot'''
'''Finally, we connect the bot and start listening for messages'''
Creating the EchoBot Class
--------------------------
There are three main types of entities within XMPP — servers, components, and
clients. Since our echo bot will only be responding to a few people, and won't need
to remember thousands of users, we will use a client connection. A client connection
is the same type that you use with your standard IM client such as Pidgin or Psi.
SleekXMPP comes with a :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>` class
which we can extend to add our message echoing feature. :class:`ClientXMPP <sleekxmpp.clientxmpp.ClientXMPP>`
requires the parameters ``jid`` and ``password``, so we will let our ``EchoBot`` class accept those
as well.
.. code-block:: python
class EchoBot(sleekxmpp.ClientXMPP):
def __init__(self, jid, password):
super(EchoBot, self).__init__(jid, password)
Handling Session Start
~~~~~~~~~~~~~~~~~~~~~~
The XMPP spec requires clients to broadcast its presence and retrieve its roster (buddy list) once
it connects and establishes a session with the XMPP server. Until these two tasks are completed,
some servers may not deliver or send messages or presence notifications to the client. So we now
need to be sure that we retrieve our roster and send an initial presence once the session has
started. To do that, we will register an event handler for the :term:`session_start` event.
.. code-block:: python
def __init__(self, jid, password):
super(EchoBot, self).__init__(jid, password)
self.add_event_handler('session_start', self.start)
Since we want the method ``self.start`` to execute when the :term:`session_start` event is triggered,
we also need to define the ``self.start`` handler.
.. code-block:: python
def start(self, event):
self.send_presence()
self.get_roster()
.. warning::
Not sending an initial presence and retrieving the roster when using a client instance can
prevent your program from receiving presence notifications or messages depending on the
XMPP server you have chosen.
Our event handler, like every event handler, accepts a single parameter which typically is the stanza
that was received that caused the event. In this case, ``event`` will just be an empty dictionary since
there is no associated data.
Our first task of sending an initial presence is done using :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>`.
Calling :meth:`send_presence <sleekxmpp.basexmpp.BaseXMPP.send_presence>` without any arguments will send the simplest
stanza allowed in XMPP:
.. code-block:: xml
<presence />
The second requirement is fulfilled using :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>`, which
will send an IQ stanza requesting the roster to the server and then wait for the response. You may be wondering
what :meth:`get_roster <sleekxmpp.clientxmpp.ClientXMPP.get_roster>` returns since we are not saving any return
value. The roster data is saved by an internal handler to ``self.roster``, and in the case of a :class:`ClientXMPP
<sleekxmpp.clientxmpp.ClientXMPP>` instance to ``self.client_roster``. (The difference between ``self.roster`` and
``self.client_roster`` is that ``self.roster`` supports storing roster information for multiple JIDs, which is useful
for components, whereas ``self.client_roster`` stores roster data for just the client's JID.)
It is possible for a timeout to occur while waiting for the server to respond, which can happen if the
network is excessively slow or the server is no longer responding. In that case, an :class:`IQTimeout
<sleekxmpp.exceptions.IQTimeout>` is raised. Similarly, an :class:`IQError <sleekxmpp.exceptions.IQError>` exception can
be raised if the request contained bad data or requested the roster for the wrong user. In either case, you can wrap the
``get_roster()`` call in a ``try``/``except`` block to retry the roster retrieval process.
The XMPP stanzas from the roster retrieval process could look like this:
.. code-block:: xml
<iq type="get">
<query xmlns="jabber:iq:roster" />
</iq>
<iq type="result" to="echobot@example.com" from="example.com">
<query xmlns="jabber:iq:roster">
<item jid="friend@example.com" subscription="both" />
</query>
</iq>
Responding to Messages
~~~~~~~~~~~~~~~~~~~~~~
Now that an ``EchoBot`` instance handles :term:`session_start`, we can begin receiving and responding
to messages. The :term:`message` event is fired whenever a ``<message />`` stanza is received, including
for group chat messages, errors, etc. Properly responding to messages thus requires checking the ``'type'``
interface of the message :term:`stanza object`.
.. _echobot_complete:

Following *XMPP: The Definitive Guide*
======================================
SleekXMPP was featured in the first edition of the O'Reilly book
`XMPP: The Definitive Guide <http://oreilly.com/catalog/9780596521271/>`_
by Peter Saint-Andre, Kevin Smith, and Remko Tronçon. The original source code
for the book's examples can be found at http://github.com/remko/xmpp-tdg. An
updated version of the source code, maintained to stay current with the latest
SleekXMPP release, is available at http://github.com/legastero/xmpp-tdg.
However, since publication, SleekXMPP has advanced from version 0.2.1 to version
1.0 and there have been several major API changes. The most notable is the
introduction of :term:`stanza objects <stanza object>` which have simplified and
standardized interactions with the XMPP XML stream.
What follows is a walk-through of *The Definitive Guide* highlighting the
changes needed to make the code examples work with version 1.0 of SleekXMPP.
These changes have been kept to a minimum to preserve the correlation with
the book's explanations, so be aware that some code may not use current best
practices.
Example 2-2. (Page 26)
----------------------
**Implementation of a basic bot that echoes all incoming messages back to its sender.**
The echo bot example requires a change to the ``handleIncomingMessage`` method
to reflect the use of the ``Message`` :term:`stanza object`. The
``"jid"`` field of the message object should now be ``"from"`` to match the
``from`` attribute of the actual XML message stanza. Likewise, ``"message"``
changes to ``"body"`` to match the ``body`` element of the message stanza.
Updated Code
~~~~~~~~~~~~
.. code-block:: python
def handleIncomingMessage(self, message):
self.xmpp.sendMessage(message["from"], message["body"])

`View original code <http://github.com/remko/xmpp-tdg/blob/master/code/EchoBot/EchoBot.py>`_
Example 14-1. (Page 215)
------------------------
**CheshiR IM bot implementation.**
The main event handling method in the Bot class is meant to process both message
events and presence update events. With the new changes in SleekXMPP 1.0,
extracting a CheshiR status "message" from both types of stanzas
requires accessing different attributes. In the case of a message stanza, the
``"body"`` attribute would contain the CheshiR message. For a presence event,
the information is stored in the ``"status"`` attribute. To handle both cases,
we can test the type of the given event object and look up the proper attribute
based on the type.
Like in the EchoBot example, the expression ``event["jid"]`` needs to change
to ``event["from"]`` in order to get a JID object for the stanza's sender.
Because other functions in CheshiR assume that the JID is a string, the ``jid``
attribute is used to access the string version of the JID. A check is also added
in case ``user`` is ``None``, but the check could (and probably should) be
placed in ``addMessageFromUser``.
Another change is needed in ``handleMessageAddedToBackend`` where
an HTML-IM response is created. The HTML content should be enclosed in a single
element, such as a ``<p>`` tag.
Updated Code
~~~~~~~~~~~~
.. code-block:: python
def handleIncomingXMPPEvent(self, event):
msgLocations = {sleekxmpp.stanza.presence.Presence: "status",
sleekxmpp.stanza.message.Message: "body"}
message = event[msgLocations[type(event)]]
user = self.backend.getUserFromJID(event["from"].jid)
if user is not None:
self.backend.addMessageFromUser(message, user)
def handleMessageAddedToBackend(self, message) :
body = message.user + ": " + message.text
htmlBody = "<p><a href='%(uri)s'>%(user)s</a>: %(message)s</p>" % {
"uri": self.url + "/" + message.user,
"user" : message.user, "message" : message.text }
for subscriberJID in self.backend.getSubscriberJIDs(message.user) :
self.xmpp.sendMessage(subscriberJID, body, mhtml=htmlBody)

`View original code <http://github.com/remko/xmpp-tdg/blob/master/code/CheshiR/Bot.py>`_
Example 14-3. (Page 217)
------------------------
**Configurable CheshiR IM bot implementation.**
.. note::
Since the CheshiR examples build on each other, see previous sections for
corrections to code that is not marked as new in the book example.
The main difference for the configurable IM bot is the handling for the
data form in ``handleConfigurationCommand``. The test for equality
with the string ``"1"`` is no longer required; SleekXMPP converts
boolean data form fields to the values ``True`` and ``False``
automatically.
For the method ``handleIncomingXMPPPresence``, the attribute
``"jid"`` is again converted to ``"from"`` to get a JID
object for the presence stanza's sender, and the ``jid`` attribute is
used to access the string version of that JID object. A check is also added in
case ``user`` is ``None``, but the check could (and probably
should) be placed in ``getShouldMonitorPresenceFromUser``.
Updated Code
~~~~~~~~~~~~
.. code-block:: python
def handleConfigurationCommand(self, form, sessionId):
values = form.getValues()
monitorPresence =values["monitorPresence"]
jid = self.xmpp.plugin["xep_0050"].sessions[sessionId]["jid"]
user = self.backend.getUserFromJID(jid)
self.backend.setShouldMonitorPresenceFromUser(user, monitorPresence)
def handleIncomingXMPPPresence(self, event):
user = self.backend.getUserFromJID(event["from"].jid)
if user is not None:
if self.backend.getShouldMonitorPresenceFromUser(user):
self.handleIncomingXMPPEvent(event)

`View original code <http://github.com/remko/xmpp-tdg/blob/master/code/CheshiR/ConfigurableBot.py>`_
Example 14-4. (Page 220)
------------------------
**CheshiR IM server component implementation.**
.. note::
Since the CheshiR examples build on each other, see previous sections for
corrections to code that is not marked as new in the book example.
Like several previous examples, a needed change is to replace
``subscription["from"]`` with ``subscription["from"].jid`` because the
``BaseXMPP`` method ``makePresence`` requires the JID to be a string.
A correction needs to be made in ``handleXMPPPresenceProbe`` because a line was
left out of the original implementation; the variable ``user`` is undefined. The
JID of the user can be extracted from the presence stanza's ``from`` attribute.
Since this implementation of CheshiR uses an XMPP component, it must
include a ``from`` attribute in all messages that it sends. Adding the
``from`` attribute is done by including ``mfrom=self.xmpp.jid`` in calls to
``self.xmpp.sendMessage``.

Example 14-6. (Page 223)
------------------------
**CheshiR IM server component with in-band registration support.**
.. note::
Since the CheshiR examples build on each other, see previous sections for
corrections to code that is not marked as new in the book example.
After applying the changes from Example 14-4 above, the registrable component
implementation should work correctly.
.. tip::
To see how to implement in-band registration as a SleekXMPP plugin,
see the tutorial :ref:`tutorial-create-plugin`.

Example 14-7. (Page 225)
------------------------
**Extended CheshiR IM server component implementation.**
.. note::
Since the CheshiR examples build on each other, see previous
sections for corrections to code that is not marked as new in the book
example.
While the final code example can look daunting with all of the changes
made, it requires very few modifications to work with the latest version of
SleekXMPP. Most differences are the result of CheshiR's backend functions
expecting JIDs to be strings so that they can be stripped to bare JIDs. To
resolve these, use the ``jid`` attribute of the JID objects. Also,
references to ``"message"`` and ``"jid"`` attributes need to
be changed to either ``"body"`` or ``"status"``, and either
``"from"`` or ``"to"`` depending on if the object is a message
or presence stanza and which of the JIDs from the stanza is needed.
