If I kill a client that uses websockets abruptly, I receive the following:

Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/gevent/greenlet.py", line 390, in run result = self._run(_self.args, *_self.kwargs) File "/usr/lib/python2.7/site-packages/gevent_socketio-0.3.5_rc3-py2.7.egg/socketio/transports.py", line 247, in read_from_ws message = websocket.receive() File "/usr/lib/python2.7/site-packages/geventwebsocket/websocket.py", line 93, in receive raise WebSocketError("Received an invalid frame_type=%r" % frame_type) WebSocketError: Received an invalid frame_type=255 <Greenlet at 0x14b74b0: read_from_ws> failed with WebSocketError

I wrapped the 'message = websocket.receive()' in a try/catch and now I get the proper 'disconnect' that I was seeking: try: message = websocket.receive() except: socket.disconnect() break

My question is is this the correct way to go about it?

Thanks much.

This shouldn't be an issue anymore. Can you test with latest master?

@Irooniam Let me know if you still have this problem in master, we are going to be making a release soon but want to make sure this is fixed.

@sontek I'll test this first thing Monday and let you know. Thanks for coming up with the (potential) fix.

That didn't seem to fix it.

I uninstalled the previous version, git-cloned master and reinstalled gevent-socketio.

Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/gevent/greenlet.py", line 390, in run result = self._run(_self.args, *_self.kwargs) File "/usr/lib/python2.7/site-packages/gevent_socketio-0.3.6-py2.7.egg/socketio/transports.py", line 259, in read_from_ws message = websocket.receive() File "/usr/lib/python2.7/site-packages/geventwebsocket/websocket.py", line 93, in receive raise WebSocketError("Received an invalid frame_type=%r" % frame_type) WebSocketError: Received an invalid frame_type=255 <Greenlet at 0x20865f0: read_from_ws> failed with WebSocketError

Can you provide an example of what you are doing so we can reproduce this?

Also, you aren't working out of a virtualenv? You are installing it directly to your system site packages?

Absolutely.

In the sio server I have a disconnect handler which just prints the socket id.

Install pywebkitgtk

You should then have a demo py script to run the webkit, mine was located at: /usr/share/doc/pywebkitgtk-1.1.8/demos/browser.py

Now run the webkit via python: python /usr/share/doc/pywebkitgtk-1.1.8/demos/browser.py

Point the browser to your socketio server and have it serve up some basic code to connect to sio server.

The sio server output looks something likes this for me: 192.168.56.101 - - [2012-11-26 09:09:37] "GET /chat.html HTTP/1.1" 200 2830 0.000383 192.168.56.101 - - [2012-11-26 09:09:37] "GET /static/css/style.css HTTP/1.1" 200 4361 0.000463 192.168.56.101 - - [2012-11-26 09:09:37] "GET /static/socket.io.js HTTP/1.1" 200 100089 0.000500 192.168.56.101 - - [2012-11-26 09:09:37] "GET /static/jquery-1.6.1.min.js HTTP/1.1" 200 91452 0.003981 192.168.56.101 - - [2012-11-26 09:09:38] "GET /favicon.ico HTTP/1.1" 404 101 0.000146 192.168.56.101 - - [2012-11-26 09:09:52] "GET /socket.io/1/websocket/777648195653 HTTP/1.1" 101 - - connect {u'name': u'abc', u'user': u'123'} with session 777648195653

Now just close the webkit or even just reload the page and you should see the error: Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/gevent/greenlet.py", line 390, in run result = self._run(_self.args, *_self.kwargs) File "/usr/lib/python2.7/site-packages/gevent_socketio-0.3.6-py2.7.egg/socketio/transports.py", line 259, in read_from_ws message = websocket.receive() File "/usr/lib/python2.7/site-packages/geventwebsocket/websocket.py", line 93, in receive raise WebSocketError("Received an invalid frame_type=%r" % frame_type) WebSocketError: Received an invalid frame_type=255 <Greenlet at 0x12640f0: read_from_ws> failed with WebSocketError

Yeah, looks like yoiu are still running the pypi version of gevent_socketio, I don't have this issue running master. I opened 2 python webkit browsers and a chrome browser to it and had them chat and disconnect and it all worked.

But by looking at your paths: /usr/lib/python2.7/site-packages/gevent_socketio-0.3.6-py2.7.egg/

seems like its installed into system libs instead of in your virtualenv.

I installed virtualenv and I still get the error.
