Delay will approximately double between attempts (random variation).
See issue #67.

Python2.6 has issues passing a Unicode string as a keyword name.
|
|
A better method than using time.sleep is needed.
Maybe use queue.task_done to detect when event processing
has ended? Research time!
|
|
|
|
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.

See issue #89
Using get_roster will now return the same types of values as
Iq.send. If a timeout occurs, then the event 'roster_timeout'
will be fired. A successful call to get_roster will also
raise the 'roster_received' event.
To ensure that the get_roster call was successful, here
is a pattern to follow:
def __init__(self, ...):
...
self.add_event_handler('session_start', self.session_start)
self.add_event_handler('roster_timeout', self.roster_timeout)
self.add_event_handler('roster_received', self.roster_received)
def session_start(self, e):
self.send_presence()
self.get_roster()
def roster_timeout(self, e):
# Optionally increase the timeout period
self.get_roster(timeout=self.response_timeout * 2)
def roster_received(self, iq):
# Do stuff, roster has been initialized.
...

Since the XEP-0086 plugin auto adds error code values,
it must be reliably loaded or unloaded when certain tests
are run so that stanzas may be matched. In this case, we
ensure that the plugin is used.
|
|
Use: self.send(None)

May now use sleekxmpp.__version__ and sleekxmpp.__version_info__.
|
|
Since camelcase names are aliased to the underscored name at startup,
if the underscored version is replaced later, the camelCase name does
not reflect the change.

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'

Backward incompatibility alert!
Please see examples/adhoc_provider.py for how to use the new
plugin implementation, or the test examples in the files
tests/test_stream_xep_0050.py and tests/test_stanza_xep_0050.py.
Major changes:
- May now have zero-step commands. Useful if a command is
intended to be a dynamic status report that doesn't
require any user input.
- May use payloads other than data forms, such as a
completely custom stanza type.
- May include multiple payload items, such as multiple
data forms, or a form and a custom stanza type.
- Includes a command user API for calling adhoc commands
on remote agents and managing the workflow.
- Added support for note elements.
Todo:
- Add prev action support.
You may use register_plugin('old_0050') to continue using the
previous XEP-0050 implementation.

Now timeouts at 0.5sec instead of 0.1sec, which should prevent test
failures from stanzas being delayed longer than usual.
|

|
|
Only 11 plugins left to tidy before 1.0!
|

|
|
Required fixing a few bugs in StanzaBase related to iterable
substanzas.
|
|
|
|
Will disable the use of TLS for the session.
|
|
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.

class name mismatch
|
|
|
|
This should prevent some reference cycles that will cause garbage
collection issues.
|
|
Don't keep a reference to stanzas in Callback objects.
|
|
|
|
|
|
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.
|
|
Allows for a callback to be canceled by unregistering the
returned handler.
|
|
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.
|
|
Now has docs and uses the new plugin format.
