[Twisted-Python] Daemonizing app (two udp servers + flask)

[Beth]

Hi!

After some code rework, I got it working.

The trick is that factories aren't supported in UPD, and they work directly
in the service creation.

Flask seems to work in the same way, not needing to be wrapped into any
factory or so. However in order not to have a .tac file loaded with the
routes and this stuff I've used flask-classy. Half an hour later everything
seems to work.

Here is my current tac file:
-----------------------------------------

from twisted.internet import reactor

from twisted.application import service, internet

from twisted.web.server import Site

from twisted.web.wsgi import WSGIResource

from flask import Flask

from server import Server

from bootloader import BootLoaderServer

from restful_api import RestFulApi


flask_app = Flask("restfulapi", static_folder="www", static_url_path="")

flask_app.debug = True

flask_resource = WSGIResource(reactor, reactor.getThreadPool(), flask_app)

flask_site = Site(flask_resource)

RestFulApi.register(flask_app)

server = Server()

server.load_cfg("default.cfg")

bootloader_server = BootLoaderServer()

application = service.Application("unidosys")

multi_service = service.MultiService()

flask_service = internet.TCPServer(8080, flask_site)

main_service = internet.UDPServer(Server.port, server)

bootloader_service = internet.UDPServer(BootLoaderServer.multicast_port,
bootloader_server)


flask_service.setServiceParent(multi_service)

main_service.setServiceParent(multi_service)

bootloader_service.setServiceParent(multi_service)

unidosys_service.setServiceParent(application)


-----------------------------------------

So far so good ;).

Thanks for your kind help and for this fantastic framework.

All the best, Beth.
