Problems with Web2PY gateway

[rpb]

Hi Nick! A happy new year to all!

Thanks for taking a look, sadly, I still have problems with the Gateway
for Web2Py(formely known as Gluon http://mdp.cti.depaul.edu/) I have
used Charles and ServiceCapture to try to debug things to no avail
because I sometimes receive no errors or this traceback:


1. Traceback (most recent call last):
 2.   File "E:\_install\_install_programm
ing\gluon_src\gluon\gluon\restricted.py",
line 66, in restricted
 3.     exec ccode in environment
 4.   File "applications/pyamf/controllers/default.py", line 24, in
<module>
 5.   File "applications/pyamf/controllers/default.py", line 16, in gateway
 6.     pyamf_request = pyamf.remoting.decode(request.body, context)
 7.   File "build\bdist.win32\egg\pyamf
\remoting\__init__.py", line
474, in decode
 8.   File "build\bdist.win32\egg\pyamf\util.py", line 151, in read_uchar
 9.     return struct.unpack("!B", self._read(1))[0]
10.   File "build\bdist.win32\egg\pyamf\util.py", line 141, in _read
11.     bytes = self.read(length)
12.   File "build\bdist.win32\egg\pyamf\util.py", line 275, in read
13.     raise EOFError
14. EOFError

Do you have any other ideas what might be going wrong here?

Can you package up everything under applications/pyamf/ and then post them
here? I can then go through with what you've got and hopefully work out
what is causing you problems ..

Thanks,

Nick

Thanks for the offer Nick. Massimo sent me the latest Web2Py AMF gateway
today, I am happy to say that it passes all the tests :-) I would write
a few sentence on how to set things up probably in a few days. The only
thing that Massimo has problems with is the handling of malfomed
requests as in the Pylons Gateway.

Thanks

Great to hear it's working. Could you maybe create a wiki page @ pyamf.org that we can add to the examples page [1]?

Cheers,

Thijs

Hi Thijs!

Sorry about the delay, this post escaped my view. I´ll be glad to create
a page with an example as soon as Web2py version 1.18 is out.

Thanks
