I am trying to get web2py set up as a WSGI server on pythonanywhere.com. That is really easy, but alongside a regular http server I also need websockets server support. Because I would like to use WAMP as protocol on top of websockets, I have chosen Autobahn, which uses Twisted. The server setup seem to be similar to the Tornado server of the EMTE example. Here is a script that starts up a Flash webapp and the Autobahn server: https://github.com/tavendo/AutobahnPython/blob/master/examples/websocket/echo_wsgi/server.py The script loading web2py on pythonanywhere basically just says "from gluon.main import wsgibase as application", but it will probably stop working if the "reactor.run()" line from the Autobahn server does not return.
I have studied the EMTE example, where the matching server is implemented in the modules dir, but I have a few questions: 1) Modules seem to be normally used for logic code in web2py, to be imported/used in controllers . that's how it is explained on the slices site as well. But the EMTE matching server seem to be a stand alone python program, is this correct? It also seems that Massimo starts up the server manually in the Vimeo video. 2) If so, is there any way to have web2py start the matching server (or a similar websockets server) when web2py is started up from the WSGI script? Is there a method I can hook into, that is called at startup - that way I could start a thread that runs the WS server rather than the __main__ from the module. I would prefer this over running the Autobahn server from the WSGI script. And while we are at it, what about closedown? 3) The EMTE matching server seem to only receive/send websocket messages and not do any database access. Can the server just import DAL and read/write the database that the regular web2py server also use? Are there any potential thread/process concurrency issues with this if the database is an SQLite file, or should a client/server SQL DB be used instead?
