Is there a wamp implementation for tornado?
Since we already use tornado, I don't want to set up twisted for this ...
Some of the features of WAMP, on top of Tornado, can be found in this open source project, TornwAMP:
https://github.com/ef-ctx/tornwamp
Not that I am aware of. FWIW, a list of WAMP implementations can be found here.

I'm trying to find some "django-socketio" repo to use in my project. I using django 1.10 and python3. I really searched but I do not found working examples with python3.
My poor workaround
I started node project and put socket.io inside route
In my django view I send returning data to node route with my django session
I manage session coming from django inside my node and emit inside
route to client.
This work but I can't believe this is a good solution.. Anyone have other ideas? Or working examples with python3 and socketio?
Thanks!
If you want to use Websockets and Django you should consider https://github.com/django/channels. The alternative in Python would be using python tornado http://www.tornadoweb.org/en/stable/ or aiohttp (Python3.4+) http://aiohttp.readthedocs.io/en/stable/. Many of the implementations of Django with asynchronousity through gevent are outdated, experimental or abandoned, I found this https://github.com/jrief/django-websocket-redis but it uses Redis so no reason to not going back to django-channels.
In my opinion, as Socket.io is a layer over Websockets you will not find any project that supports fully the Socket.io spec as a ws server in Python as it is a native Node.js not officially ported to Python project, at least the latest one you are probably using, if you really need Socket.io features stick to Node.js and create a simple REST API in Django to load the backend data asynchronously from Nodejs (the REST django API will always be synchronous by nature), this is the best shot you would likely have.

django-channels works with python3 and django >=1.8 :)
And you can change pip to pip3
I have a web application im currently working on in python. I'm using Django as my web framework currently. I intend to integrate real-time web features into the application using ajax push. However, I'm a bit confused as to what python based push server i should adopt. I've heard of a few of them, Orbited, Gevent, Tornado, but my main issue right now is that i'm a green horn when it comes to realtime web applications. I'd like to use python and i'd like a framework with good documentation.
A lot of people choose gevent for webapps with real-time features because of the speed, ease of use and a number of supporting packages.
Take a look at these packages:
gevent-socketio
django-socketio
and these tutorials:
Evented Django part one: Socket.IO and gevent
New and hot, part 4: Pyramid, Socket.IO and Gevent
Real-time Web Apps with Django and WebSockets
Hope this helps.
APE seems a cool thing.
I think it's not a problem to make it work with PDjango as a backend.
I think the most popular is tornado open-sourced by facebook. It also has pretty decent documentation.
I've built my application in python (using greenthreads from eventlent) and I was supposed to use Orbited as comet server to pass requests from user-end javascript code to my application.
Sadly, I found that Orbited is dead, site is down for a few weeks and it lack python 2.7 support.
Could you recommend some good replacements?
You could build a comet server using gevent, meinheld, mongrel2, tornado, twisted, or uwsgi, all of which have long-polling examples. This list isn't exhaustive. You could also consider using WebSockets instead, several have WebSocket examples as well.
I haven't used it personally, but it seems that CometD has a Twisted-based implementation of its protocol.
It seems that for now the best option is to use Socket.io, which offer simple and feature-rich programming interface both on server and client side. The python options are:
gevent-socketio
SocketTornad.IO
socketIO-client

Probably that won't register as an answer as you are looking for a server written in Python. Still, I would recommend this efficient server written in Perl. After all, IMHO, as an out-of-the-box/off-the-shelf solution it's as good as any other Python-based server can get.
I want to access web service in Python or/and Perl scripts. What are the most popular and reliable libraries today?
I read this question, and I know about SOAPpy and ZSI. Can anybody say something about this libraries? Are they reliable enough for use in production?
If you're talking about SOAP then for Python I would definitely recommend suds :
https://fedorahosted.org/suds/
Checking couple of libraries for SOAP (including suds) only ZSI worked reliably for me. It is not complicated to use and it just works(tm). I recommend that.
Perl has fantastic CPAN libraries available for doing SOAP. Probably the easiest would be SOAP::Lite:
SOAP::Lite is a collection of Perl modules which provides a simple and lightweight interface to the Simple Object Access Protocol (SOAP) both on client and server side.
See more on the CPAN page.
Can you tell me: could I use twisted for p2p-applications creating? And what protocols should I choose for this?
The best solution is to use the source code for BitTorrent. It was built with Twisted until they switched over to a C++ implementation called Utorrent.
Last known Twisted version of BitTorrent
http://download.bittorrent.com/dl/archive/BitTorrent-5.2.2.tar.gz
Older versions
http://download.bittorrent.com/dl/archive/
As an alternative, you also might want to take a look at Vertex.
It is a p2p library built on top of Twisted and comes with goodies like bypassing firewalls.
Its probably more complete than the other people's sample.
Link to Vertex
https://github.com/twisted/vertex
bittorrent twisted python client/server
Yes, twisted was used to create the initial version of Bittorrent. There are some opensource libraries to start from.
Yes, you can absolutely use twisted to create a p2p application. The one that comes first to my mind is Dtella (http://dtella.org/). It's uses the Direct Connect protocol.
They provide the source code, so that could get you started. I know that quite a few different university networks have DC hubs running. That seems to be the ideal use of this protocol.
