OpenDNA Autobahn-Python Runners
===============================
The OpenDNA Autobahn-Python Runners package provides a number of scripts that
can be used to launch Autobahn-Python components and connect them to a WAMP
router.
Contents
--------
1. Installation
2. Usage
3. Command-line Parameters
4. Twisted Runner
5. AsyncIO Runner
6. AsyncIO Multi-Runner
7. Roadmap
Installation
------------
``pip install autobahn-python-runners``
When the package is installed it will create the following scripts in your
Python environment's scripts path:
- ``run_twisted_component``
- ``run_asyncio_component``
- ``run_asyncio_components``
Optionally, you ``pip install uvloop`` for enhanced event-loop perforance with
the AsyncIO runners. You will need ``libuv`` with installed in order to do this.
Usage
-----
Usage can be achieved through one of two methods:
0. Execute one of the scripts created during installation
1. Execute one of the modules using the standard ``python -m`` method
Command-line Parameters
-----------------------
The following command-line parameters are supported by all of the runners
included in this package:
Required parameters:
- ``-c`` or ``--component`` is a fully-qualified path to an Autobahn-Python
component class E.g. ``some_org.some_package.some_module.SomeClass``. Can be
alternatively specified using the ``WAMP_COMPONENT`` enviornment variable
- ``-u`` or ``--url`` is a URL for the WAMP router to connect to
E.g. ``ws://localhost:8080``. Can be alternatively specified using the
``WAMP_URL`` environment variable
- ``-r`` or ``--realm`` is a Realm on the WAMP router you are connecting to. E.g.
``my.realm.name``. Can be alternatively specified using the ``WAMP_REALM``
environment variable
Optional parameters:
- ``-e`` or ``--extra-file`` is a path to a JSON file which will be loaded and
supplied to the component class instance via the config parameter of the
class constructor method
- ``-s`` or ``--use-ssl`` is value that will be cast to a boolean and used to
specify whether or not SSL should be used for the WS connection. This
parameter is usually unnecessary as the decision to use SSL is usually
determined by the choice of WS protocol for the WAMP router URL. It is made
available here simply for the purposes of completeness
- ``-l`` or ``--loglevel`` is used to specify the logging level used by the runner.
Defaults to ``info`` with other permitted values being ``critical``, ``error``,
``warning`` and ``debug``
- ``--serializers`` is a fully qualified path to an Autobahn-Python serializer
class. This parameter may be specified multiple times
Twisted Runner
--------------
The Twisted runner is provided by the ``opendna.autobahn.runners.run_twisted``
module and can be used to run components that derive from the
``autobahn.twisted.ApplicationSession`` class.
AsyncIO Runner
--------------
The AsyncIO runner is provided by the ``opendna.autobahn.runners.run_asyncio``
module and can be used to run components that derive from the
``autobahn.asyncio.ApplicationSession`` class.
AsyncIO Multi-Runner
--------------------
The AsyncIO multi-runner is provided by the ``opendna.autobahn.runners.multirun_asyncio``
module and can be used to run multiple components that derive from the
``autobahn.asyncio.ApplicationSession`` class within a single Python process.
These components will run within a single event-loop but each component will
establish a separate WS connection to the WAMP router.
The AsyncIO multi-runner makes the following changes to the parameter options:
- ``-c``/``--component`` may be passed multiple times in order to specify
multiple component classes. Each class instance will connect to the same
WAMP router and realm specified using the relevant parameters
- ``-e``/``--extra-file`` can still be used but behaves slightly differently in
that it expects that the JSON file will contain a plain object where each
key is a component class as specified using the ``-c``/``--component`` parameter
and the value associated with each key is a plain object of data to be supplied
to the relevant component class instance via the config parameter of the
class constructor method
- ``-n``/``--necromancy`` is used to enable the transport recovery feature. When
enabled the multi-runner will periodically check to see if the WAMP connection
between a component and the router has failed. If a failure is detected then
a new component instance is created and will attempt to connect to the router
- ``--necromancy-sleep`` accepts integers and defaults to ``10``. This parameter
specifies how regularly the check for failed WAMP connections will be performed
Roadmap
-------
Done:
- Twisted runner
- AsyncIO runner
- AsyncIO multi-runner
- Basic documentation
- uvloop support for AsyncIO runners
- Option for multi-runners to transparently restart crashed components
Todo:
- Tests
Maybe:
- Twisted multi-runner
