New description:
I found (and fixed) the following bugs in the file local/lib/python2.6
/site-packages/sagenb-0.8-py2.6.egg/sagenb/simple/twist.py:
* When trying to login via the Simple Sage Server API using the
sagenb.notebook.notebook_object module the following error came up:
{{{
....
/sagenb-0.8-py2.6.egg/sagenb/simple/twist.py, line 206, in render
U = notebook_twist.notebook.user(username)
exceptions.AttributeError: 'NoneType' object has no attribute 'user'
}}}
The problem is: The sagenb twist.py module still imports the (old and
unmaintained) sage.server modules instead of the new sagenb files. It is
quite logical that there is a NoneType error because there is no server
started that relies on the (imported) old files.
If the two imports from sage.server in twist.py are replaced with the
sagenb modules at least the login via Simple Sage Server API works quite
fine.
* When login works there is another bug: On line 286 in the twist.py file
where it says "return http.Response(..." the stream variable has to be
converted into a string (twisted somehow seems to have problems with
unicode characters because IByteStream(stream) which is called in
http.Response() fails with a TypeError if stream is of type 'unicode').
