This is a work in progress abstraction class to handle freeswitch's eventsocket command lines.

Project Description

This is a work in progress abstraction class to handle freeswitch’s eventsocket command lines.

Currently only inbound server is implemented.

Implementation under Tornado’s IOLoop

Here is a simple server implementation under Tornado:

import eventsocket

from tornado.tcpserver import TCPServer
import tornado.ioloop
from tornado.gen import coroutine, Return


class TestServer(eventsocket.BaseEventSocket, TCPServer):

    @coroutine
    def handle_stream(self, stream, address):
        self.stream = stream
        self.on_connect()

    @coroutine
    def send_and_receive(self, chunk):
        yield self.stream.write(chunk)
        _ = yield self.stream.read_until_regex(b'\n\n')
        raise Return(self._parse_event(_))

    @coroutine
    def on_connect(self):
        print 'connected!'
        data = yield self.connect()
        print data
        yield self.my_events()
        yield self.answer()
        yield self.playback(
            '{loops=10}tone_stream://path=${base_dir}/conf/tetris.ttml',
            lock=True
        )


if __name__ == '__main__':
    server = TestServer()
    server.listen(8888, '0.0.0.0')
    tornado.ioloop.IOLoop.instance().start()

Implementation under Twisted’s Reactor

Here is a simple server implementation under Twisted:

import eventsocket

from twisted.internet import defer, protocol
from twisted.protocols import basic

from cStringIO import StringIO


class TestServer(eventsocket.BaseEventSocket, basic.LineReceiver):

    delimiter = '\n'

    def __init__(self, *args, **kwargs):
        self.stream = None
        self._io = StringIO()
        self._queue = []
        super(TestServer, self).__init__(*args, **kwargs)

    def lineReceived(self, line):
        if len(line) > 0:
            self._io.write('%s\n' % line)
        else:
            self.dispatch_event()

    def dispatch_event(self):
        try:
            deferred = self._queue.pop(0)
        except IndexError:
            pass
        else:
            self._io.reset()
            _ = self._parse_event(self._io.read())
            deferred.callback(_)
            self._io.reset()
            self._io.truncate()

    def send_and_receive(self, chunk):
        deferred = defer.Deferred()
        self._queue.append(deferred)
        self.transport.write(chunk)
        return deferred

    @defer.inlineCallbacks
    def connectionMade(self):
        print 'connected!'
        data = yield self.connect()
        print data
        yield self.my_events()
        yield self.answer()
        yield self.playback(
            '{loops=10}tone_stream://path=${base_dir}/conf/tetris.ttml',
            lock=True
        )


class PubFactory(protocol.Factory):

    def buildProtocol(self, addr):
        return TestServer()


if __name__ == '__main__':
    from twisted.internet import reactor

    reactor.listenTCP(8888, PubFactory())
    reactor.run()
