A service-oriented component model framework
Project description
iPOPO : A component model for Python
iPOPO is a Python-based Service-Oriented Component Model (SOCM) based on Pelix, a dynamic service platform. They are inspired on two popular Java technologies for the development of long-lived applications: the iPOJO component model and the OSGi Service Platform. iPOPO enables to conceive long-running and modular IT services.
See https://ipopo.coderxpress.net for documentation and more information.
iPOPO is available on PyPI and is released under the terms of the Apache License 2.0.
Feedback
Feel free to send feedback on your experience of Pelix/iPOPO, via the mailing lists :

Compatibility
Pelix and iPOPO are tested using Tox and Travis-CI with Python 2.6, 2.7, 3.2 and 3.3.
It is also manually tested with Pypy 1.9 and Python 3.4.
To use iPOPO on Python 2.6, it is necessary to install the importlib module back-port, using pip install importlib. To execute iPOPO tests on this version, you also need to install the unittest2 module.
Release notes
See the CHANGELOG.rst file to see what changed in previous releases.
iPOPO 0.5.7
Project
Code review to be more PEP-8 compliant
jsonrpclib-pelix is now an install requirement (instead of an optional one)
Framework
Forget about previous global members when calling Bundle.update(). This ensures to have a fresh dictionary of members after a bundle update
Removed from pelix.constants import * in pelix.framework: only use pelix.constants to access constants
Remote Services
Added support for endpoint name reuse
Added support for synonyms: specifications that can be used on the remote side, or which describe a specification of another language (e.g. a Java interface)
Added support for a pelix.remote.export.reject service property: the specifications it contains won’t be exported, event if indicated in service.exported.interfaces.
Jabsorb-RPC:
Use the common dispatch() method, like JSON-RPC
MQTT(-RPC):
Explicitly stop the reading loop when the MQTT client is disconnecting
Handle unknown correlation ID
Shell
Added a loglevel shell command, to update the log level of any logger
Added a --verbose argument to the shell console script
Remote shell module can be ran as a script
HTTP
Remove double-slashes when looking for a servlet
XMPP
Added base classes to write a XMPP client based on SleekXMPP
Added a XMPP shell interface, to control Pelix/iPOPO from XMPP
Miscellaneous
Added an IPv6 utility module, to setup double-stack and to avoids missing constants bugs in Windows versions of Python
Added a EventData class: it acts like Event, but it allows to store a data when setting the event, or to raise an exception in all callers of wait()
- Added a CountdownEvent class, an Event which is set until a given
number of calls to step() is reached
threading.Future class now supports a callback methods, to avoid to actively wait for a result.
