Hi,
I'm playing with the Channel API at the moment. It's good! And by
playing, I mean implementing in a commercial product (of course).
It's all working happily, I just have a minor niggle that it's killing
my dev appserver. Basically, as soon as I call channel.open(), blamo!
The appserver goes down like a ton of bricks. So for an app that's
relying fairly heavily on the channel API, the dev appserver unusable
like this.
Here's a test page:
<html>
<head></head>
<body>
<script type="text/javascript" src="/_ah/channel/jsapi"></script>
<script>
channel = new goog.appengine.Channel('xyz');
socket = channel.open();
</script>
Hello
</body>
Here's the result:
===========================

===========================
I'm using python 2.7 and sdk 1.6.0
I've just checked that if I switch back to python 2.5 (ie: runtime:
python instead of runtime: python27) then it seems to work. However,
that's not really an option, as I'm becoming fairly dependent on
python 2.7 now throughout my app.
Any workarounds, hacks, fixes even? Or just ideas?
