ElementBase instances will display the top-most namespace by default.
StanzaBase instances will NOT display the top-most namespace by default.
May pass True or False to __str__ to override.
We need to check if type="get". otherwise we will send our version
when we will receive the version of the remote entity, and thus
going in an infinite loop.
Can now be used as so:
>>> msg['chat_state']
''
>>> msg
<message />
>>> msg['chat_state'] = 'paused'
>>> msg
<message>
<paused xmlns="http://jabber.org/protocol/chatstates" />
</message>
>>> msg['chat_state']
'paused'
>>> del msg['chat_state']
>>> msg
<message />
Now done more responsibly, saving any existing signal handlers
and calling them when an interrupt occurs in addition to the
one Sleek installs.
NOTE: You may need to explicitly use "kill <process id>" in
order to trigger the proper signal handler execution, and
to raise the "killed" event.
Instead of the actual callback object, return just the name of
the callback object created when using iq.send(callback=..).
This will help prevent memory leaks by not keeping an additional
reference to the object, but still allows for the callback to be
canceled by using self.remove_handler("handler_name").
Waiting until the actual run step means that the handler is not
marked for deletion when checked in the __spawn_event() thread,
causing the callback to stay in the handler list.
This allows exceptions to include the original
content of a stanza in the error response by including
the parameter clear=False when raising the exception.
Stream features now use stanza objects!
Features are given a ranking that expresses the dependency
relationships (since only one feature is negotiated at a time, the
dependency graph can be replaced by a line).
>>> xmpp.register_feature('my_feature', _my_handler,
>>> restart=True, # Requires stream restart
>>> order=600) # Ranking (out of ~ 10,000,
>>> # lower #'s executed first)
SASL mechanisms may now be added or disabled as needed. Each mechanism
is given a priority value indicating the order in which the client
wishes for mechanisms to be tried. Higher priority numbers are executed
first.
>>> xmpp.register_sasl_mechanism('SASL-MECH', _mech_handler,
>>> priority=0)
Disabling a SASL mechanism:
>>> xmpp.remove_sasl_mechanism('ANONYMOUS')
Will now always show top-level namespace, unless it is the same
as the stream's default namespace. Also added the XMPP stream
namespace to the namespace map as 'stream'.
Use stanza.values instead of _get/set_stanza_values where used.
ElementBase stanzas can now use .tag
May use class method tag_name() for stanza classes.
ElementBase now has .clear() method.
May now use register_stanza_plugin(Foo, Bar, iterable=True)
to add to the set of stanza classes used for iterable
substanzas. It is no longer necessary to manually specify
the contents of subitem if the new method is used.
A stanza object may add is_extension = True to its class definition
to provide a single new interface to a parent stanza.
For example:
import sleekxmpp
from sleekxmpp import Iq
from sleekxmpp.xmlstream import ElementBase, register_stanza_plugin, ET
class Foo(ElementBase):
"""
Test adding just an attribute to a parent stanza.
Adding subelements works as expected.
"""
is_extension = True
interfaces = set(('foo',))
plugin_attrib = 'foo'
def setup(self, xml):
# Don't include an XML element in the parent stanza
# since we're adding just an attribute.
# If adding a regular subelement, no need to do this.
self.xml = ET.Element('')
def set_foo(self, val):
self.parent()._set_attr('foo', val)
def get_foo(self):
return self.parent()._get_attr('foo')
def del_foo(self):
self.parent()._del_attr('foo')
register_stanza_plugin(Iq, Foo)
i1 = Iq()
i2 = Iq(xml=ET.fromstring("<iq xmlns='jabber:client' foo='bar' />"))
>>> i1['foo'] = '3'
>>> i1
'3'
>>> i1
'<iq id="0" foo="3" />'
>>> i2
'<iq id="0" foo="bar" />'
>>> i2['foo']
'bar'
>>> del i2['foo']
>>> i2
'<iq id="0" />'
We now raise the unexpected exceptions instead of sending
them on the network.
- avoids flood (sending a traceback on a MUC, for example…) and
maybe some security issues.
- lets you handle the traceback (catch it to handle
it properly, or with except_hook, etc)
- an exception cannot be raised without you knowing
Daemonized threads exit once the main program has quit,
and the only threads left running are all daemon threads.
Should fix hanging clients while not trampling over anyone
else's signal handlers.
Methods now accept either an ifrom or mfrom parameter
to specify a 'from' value. Client connections should not
need to use these, but component connections must use them.
May include a to and from JID in make_iq_* calls.
May pass an existing iq stanza to most of them instead of generating
a new stanza.
make_iq now accepts a 'to' value, 'type' value, and 'query' value to
simplify things a bit more.
Now with dynamic node handling goodness.
Some things are not quite working yet, in particular:
set_items
set_info
set_identities
set_features
And still need more unit tests to round things out.
Support is only for adding literal XML content
to stanzas. Full support for things like multiple
message bodies with different xml:lang values is
still in the works.
The callback will be a stream level handler, and will not
execute in its own thread. If you must have a thread, have the
callback function raise a custom event, which can be processed
by another event handler, which may run in an individual thread,
like so:
def handle_reply(self, iq):
self.event('custom_event', iq)
def do_long_operation_in_thread(self, iq):
...
self.add_event_handler('custom_event', self.do_long_operation_in_thread)
...take out already prepared iq stanza...
iq.send(callback=self.handle_reply)
SleekTest can now use matchers when checking stanzas, using
the method parameter for self.check(), self.recv(), and self.send():
method='exact' - Same behavior as before
'xpath' - Use xpath matcher
'id' - Use ID matcher
'mask' - Use XML mask matcher
'stanzapath' - Use StanzaPath matcher
recv_feature and send_feature only accept 'exact' and 'mask' for now.
Just catch an other exception type coming from the dns resolver that
could be raised with hosts like "anon.example.com" which just don't have
any SRV record.
* check_stanza does not require stanza_class parameter. Introspection!
* check_message, check_iq, and check_presence removed -- use check
instead.
* stream_send_stanza, stream_send_message, stream_send_iq, and
stream_send_presence removed -- use send instead.
* Use recv instead of recv_message, recv_presence, etc.
* check_jid instead of check_JID
* stream_start may accept multi=True to return a new SleekTest instance
for testing multiple streams at once.
xep_0030 still referenced event_handlers. Added the method event_handled
which will return the number of registered handlers for an event to
resolve the issue.
Setting signal handlers from inside a thread is not supported in Python,
but some applications need to run Sleek from a child thread.
SleekXMPP applications that run inside a child thread will NOT be able
to detect SIGHUP or SIGTERM events. Those must be caught and managed by
the main program.
Made setting the SIG* handlers conditional on if the signal defined for
the OS.
Added the attribute ssl_version to XMLStream to set the version of SSL
used during connection. It defaults to ssl.PROTOCOL_TLSv1, but OpenFire
tends to require ssl.PROTOCOL_SSLv23.
Raising an XMPPError exception from an event handler now works, even if
from a threaded handler.
Added stream tests to verify.
We should start using XMPPError, it really makes things simple!
Stanza objects now accept the use of underscored names.
The CamelCase versions are still available for backwards compatibility,
but are discouraged.
The property stanza.values now maps to the old getStanzaValues and
setStanzaValues, in addition to _set_stanza_values and
_get_stanza_values.
It is now possible to ask for "any number of history stanzas" when
joining a muc (with history=None).
Also we use "maxchars" when asking NO history ("0") since it's a MUST in
the XEP.
And you can specify a message when leaving a MUC.
