Official repository for gevent-socketio

I tried to change the namespace from "socket.io" to another string and the framework does not work. Any ideas where are all the places where I have to make changes? I thought it is only the constructor on the server side

SocketIOServer(('127.0.0.1', 8080), app,
        namespace="newnamespace", policy_server=False).serve_forever()

And on the client

// socket.io specific code
var socket = io.connect("http://localhost:8080/newnamespace", { resource : "newnamespace"
});

Hi guys,

When I use the worker socketio.sgunicorn.GeventSocketIOWorker gunicorn doesn't log access logs. The file is created but its always empty.

Any ideas?

Here is the error from IE 8 browser - its triggers a JS exception

It appears that socket.io 1.0 has been released: http://socket.io/blog/introducing-socket-io-1-0/

There are new protocols: https://github.com/automattic/engine.io-protocol and https://github.com/automattic/socket.io-protocol

Nginx is often put in front of other webservers, but does not support web-sockets. This is generally fine, however if using the gunicorn worker, you cannot unset the websocket transport. This causes a traceback about a missing wsgi.web_socket key. There is already a closed issue about this.

Additionally, I added an Nginx specific worker class which sets the transport to xhr-polling. This appears to be the only transport which is currently working. It appears that there are several broken transports.

How do I serve my Django site using uWSGI with the SocketIOServer? I tried using the following uwsgi config:

[uwsgi]
socket = 127.0.0.1:3031
master = true
processes = 2
env = DJANGO_SETTINGS_MODULE=demo.settings
module = run

and I have run.py:

from gevent import monkey
from socketio.server import SocketIOServer
import django.core.handlers.wsgi
import os
import sys

monkey.patch_all()

PORT = 3031

os.environ['DJANGO_SETTINGS_MODULE'] = 'demo.settings'

application = django.core.handlers.wsgi.WSGIHandler()
SocketIOServer(('', PORT), application, namespace="socket.io").serve_forever()

but it just keeps on loading. Any ideas on how I might tell uWSGI to use SocketIOServer for serving my app?

If I run my server with n worker, and I connect n+1 clients, emit_to_room delivers the same message multiple times to every client.

Steps to reproduce:

1. run your server with n workers.
2. connect n+1 clients and make them join the same channel
3. push a message with emit_to_room

This is the code that I'm using (please ignore my re-implementation of emit_to_room there).

I would like for someone to confirm it's actually a bug and not just me. If it's actually a bug, I am ready submit a pull request.

It looks to me from running the simple chat example (and other applications) under Dozer (https://bitbucket.org/bbangert/dozer) that gevent-socketio is leaking a socketio.virtsocket.Socket and geventwebsocket.websocket.WebSocketHybi on every disconnect (along with a host of related/connected gevent/greenlet things).

The problem, as best as I can see, is that although kill() runs when the socket disconnects, the socket itself is never actually disposed of. From looking at the dozer output it seems like the problem may be that the environ dict is never deleted, so references remain to the websocket and socketio objects. I don't know if that's right (or even reasonable), or what to do to fix it.

When i do a pip install gevent-socketio on a new box, I get a really old version of gevent-socketio. Here is what I see

gevent==0.13.8
gevent-socketio==0.3
gevent-websocket==0.3.6
greenlet==0.4.1

Any idea why? This is more than a year old code and bug fixes that I contributed a year ago are missing.

I am trying to use gevent-socketio to perform some tasks a remote server running the python script that uses gevent-socketio . I am using socketio in as a web client. I have based this on the simple chat example. I have the client talking to the server and I and can get the server to print messages and do basic actions when a button is pressed on the web interface. However, when I run a long or CPU intensive (I don’t know which is the cause) operation on the def on_yyy event the clients get disconnected. Any ideas? Many Thanks Edd

I am using gunicorn with a socketio.sgunicorn.GeventSocketIOWorker worker to run a django project. When a websocket request arrives, the "socketio" key does not appear in the request.environ dictionary. What can be the reason for that?

The request.environ dictionary:

I use the example of simply_pyramid_chat for your project. I started a project with pserve pyramid, use view.py from the example. But I received KeyError: 'socketio' in socketio.init.py socketio_manager line 67

    socketio_manage(request.environ, {'/chat': TestNamespace}, request=request)

What could be the problem? Thanks!

I need to talk with a socket.io server -- it it possible to use gevent-socketio as a client, connecting to a websocket on a server and then exchanging realtime messages?

Hi!

There seem to be a number of post-0.3.6 commits in Git that never got to PyPI. (The fix I'd need in a release is 12da9667deba432d8917129afab1daa86c20ec84 in particular.) I find these unreleased fixes in Git:

• git cherry -v 668d11edbd62052cde1583be1e1d0512c930f16d | tac
  • 0e1d9d5d461530724522d12d592cde9fc68264a9 Add support for Django 1.10
  • 9a6e024e056964c3d860316d5b13b295ed80d379 Drop support for Django 1.3
  • a76b50ea257dc4aec0ad2610d8d5281ce478565d Updated travis install command.
  • 1b5167054907b94a7c8dda7f95871661bbf285a2 Expanded Python test versions.
  • 469ed83d11d62684e07798781014b4f2dde89b0d Added tox configuration for running tests across multiple Python versiosn. Fixed Python3 support.
  • acf095b78208edb59b5873662653e12773add3cc Fixed import to support Django>=1.9.
  • 1c84627980c0b77f8f9005fdbcc916ca33d0e4d1 Leadership note.
  • 13cd65e6e47fffe91a34f14b4030b14382de3963 Travis script fix
  • 12da9667deba432d8917129afab1daa86c20ec84 Full Python 2+3 support

Is there a chance to get a new release tagged and uploaded to PyPI?

Thanks in advance!

Hi!

Since I didn't find a Git tag for release 0.3.6 I tried to find a Git commit with a tree matching the 0.3.6 tarball on PyPI. Interestingly, there doesn't seem to be any exact match. 668d11edbd62052cde1583be1e1d0512c930f16d is close but it lacks two files that PyPI has:

• socketio/exceptions.py
• socketio/storage.py

While socketio/storage.py seems to never have bin in Git at all, socketio/exceptions.py never was in that state (containing a single class SessionNotFound).

Anyone got an idea about these two files? Should 668d11edbd62052cde1583be1e1d0512c930f16d still be tagged as 0.3.6?
