Stomp / IE6 fixes) so I'd

[Michael Carter]

Hello,

It appears that there was some strange caching bug in IE6 that was introduced over the past few weeks. I've cleaned that up, and also switched streaming back on in IE6 as the default. (To go back to long polling use Orbited.settings.streaming = false;)

I also added a stomp.reset function which you'll probably want to call onunload.

Before I make a 0.7.2 release, I'd like some feedback from the trunk. I've only tested this in IE6 under a very strange setup (IE6 on wine on ubuntu) so I'd like to hear back from windows users.


To try out trunk, do the following:

1) svn co http://orbited.org/svn/orbited/trunk/daemon orbited
2) cd orbited
3) python setup.py install
4) orbited --config orbited-debug.cfg
5) visit http://localhost:8001/static/demos/stomp
6) test connect, subscribe, send, and page reload

Michael, I get this error on step 4 (orbited --config orbited-
debug.cfg) - the earlier steps worked ok, I have an earlier version of
Orbited on my machine which may have caused the error?:

Open the orbited-debug.cfg file and remove the reactor=epoll line.

Ok commented that out, now orbited starts up ok.

I hit the 'connect' button leaving the default 'guest' values, get:

→ Transport closed (code: 108)

in the output area of the page. I think this is the corresponding
error in output:

11/15/08 09:18:39:593 ACCESS new connection from 127.0.0.1:4247 to
localhost:616

'twisted.
internet.error.ConnectionRefusedError'>: Connection was refused by
other side: 1
0061: No connection could be made because the target machine actively
refused it
..]

Sorry for the simple error again, what do I add to where to get past
this one?

It seems you don't have any STOMP broker running (they normally listen
at port 61613).

You should read the documentation at
http://orbited.org/wiki/Documentation more exactly the MorbidQ at
http://orbited.org/wiki/MorbidQ.

I've tested this by deploying the "Orbited + Morbid + js.io graph"
demo on a remote server and connecting with IE7(not allowed to install
IE6 on this computer).

As suggested in http://groups.google.com/group/orbited-users/browse_thread/thread/53edb870f0237494
I first tried to use long polling, which produces the exact same
result as before. Page loads and works fine on first try, and fails
after reload. Then I tried without forcing long polling. This also
used to work fine on first try, but now I get "Lost connection, Code:
101". Orbited prints this stacktrace which repeats itself several
times.

Needless to say, everything works like a charm in FF3 :)

Have you tested this against 0.7.2 (trunk) ?

also, try installing the cjson package (python-cjson on debian/ubuntu)

Thanks a lot Michael, it is definitely working better now. :) I am
getting some mixed result though.

Adding onunload = function() { stomp.reset(); } will make everything
work IF you don't hit an identical page bar the onunload bit first.
For example: Page A does not do unonload while page B does. Hitting A
first and then going to B and reloading B will break the connection
for the rest of the process' life cycle it seems. It's a non-issue
though; you won't be including a broken page in the first place :)
Restarting IE7 and going straight to page B and reloading B will work
almost all the time. Once or twice I get the old access denied error,
but after another reload it might go away. Restarting IE7 again can
also clear the problem. I've cleared all temporary data in IE7 and
will keep trying. So far so good.

Thanks again / Fredrik

Oh and yes, I am testing against trunk, and cjson was not
installed. :)
