If a stanza handler raised an exception, the exception was processed
and replied by the modified stanza, not a stanza with the original
content.
A copy is now made before handler processing, and if an exception occurs
it is the copy that processes the exception using the original content.
|
|
|
|
For now, session_end is the same as disconnected, but once support is
added later for stream management, the two events will become distinct.
Plugins should add handlers for session_end for cleaning any session
state.
|
|
|
|
The stanza will be sent first once the send queue is reactivated
after session start.
Stanzas sent by skipping the queue will not be cached.

Backoff was only being done for the initial connection attempt
before. Now any reconnection will start with a minimum 1 sec
delay which will approximately double between attempts.
|
|
The syntax and attribute errors raised during a disconnect/reconnect
attempt are now caught and produce nicer log messages.
|
|
Use the parameter now=True to skip the queue when
sending Iq stanzas, or using xmpp.send().
|
|
|
|
Delay will approximately double between attempts (random variation).
See issue #67.

JIDs with Unicode values were being encoded by the JID class
instead of leaving them as just Unicode strings.
It may still be a good idea to use
from __future__ import unicode_literals
pretty much everywhere though.
Fixes issue #88.

Each interface, say foo, may be overridden in three ways:
set_foo
get_foo
del_foo
To declare an override in a plugin, add the class field
overrides as so:
overrides = ['set_foo', 'del_foo']
Each override must have a matching set_foo(), etc method
for implementing the new behaviour.
To enable the overrides for a particular parent stanza,
pass the option overrides=True to register_stanza_plugin.
register_stanza_plugin(Stanza, Plugin, overrides=True)
Example code:
class Test(ElementBase):
name = 'test'
namespace = 'testing'
interfaces = set(('foo', 'bar'))
sub_interfaces = set(('bar',))
class TestOverride(ElementBase):
name = 'test-override'
namespace = 'testing'
plugin_attrib = 'override'
interfaces = set(('foo',))
overrides = ['set_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, value):
print("overrides!")
self.parent()._set_attr('foo', 'override-%s' % value)
register_stanza_plugin(Test, TestOverride, overrides=True)
Example usage:
>>> t = TestStanza()
>>> t['foo'] = 'bar'
>>> t['foo']
'override-bar'

Required fixing a few bugs in StanzaBase related to iterable
substanzas.

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.

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.

This should prevent some reference cycles that will cause garbage
collection issues.
|
|
Don't keep a reference to stanzas in Callback objects.
|
|
|
|
|
|
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.
|
|
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'.
|
|
This allows you to determine the order in which substanzas
were added in the original XML.
|
|
|
|
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" />'

Will be most useful for debugging and responding to failed
connection attempts.
|
|
Fixes the intermittent DEBUG ((),) messages that give no
explanation.
Will now show as:
DEBUG Scheduled event: ((), )
|
|
|
|
Two JIDs match if they have the same full JID value.
|
|
May now use sys.excepthook to catch exceptions
from threaded handlers.
|
|
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.

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.
