[Spyce-users] session/cookie questions

[Steven D. A. <st...@ne...>]

I may be having some serious misconceptions about how session works, but I
wonder if anyone can point out the mistake(s) I'm making here.  I've tried
to reduce the problem to the minimum amount of code possible.

Essentially, the problem is that I can't seem to get session functionality
-- values simply aren't saved from page to page.  To recreate the problem, I
developed three small files -- a header and two pages, once of which loads
the other.  I set a session value in the first page, and it doesn't show up
in the second.

The header file looks like this:

[[.import name=session args="'session_dir', '/home/thoth/httpd/session',
auto=28800"]]
[[\
    def generate_cookie( length=30 ):
        import random
        chars = 
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
        cookie = ''
        for i in range( length ):
            cookie += random.choice( chars )
        return cookie
    sessionid = cookie.get( 'unr_session' )
    if not sessionid:
        sessionid = generate_cookie()
        cookie.set( 'unr_session', sessionid )
    session_dict = session.get( sessionid )
    if not session_dict:
        session_dict = {}
]]

This file fetches a dictionary stored under the sessionid.  If there is no
dictionary there, it creates one.

The first page looks like this:

[[.import name=include]]
[[.include file=testheader.spy]]
[[\
    # Set a value in the session dict
    session_dict[ 'foo' ] = 'bar'
    session.set( session_dict, 3600, sessionid )
    include.spyce( "test_page2.spy" )
    return
]]

Note this file sets the 'foo' key in the session_dict dictionary, then saves
the dictionary under the sessionid, and finally includes the next page.

The second page looks like this:

[[.import name=include]]
[[.include file=testheader.spy]]
[[\
    from sys import stderr as err
    print >>err, "session_dict[ 'foo' ] = ", session_dict[ 'foo' ]
]]

When I load the first page, it executes its code and then loads the second
page.  The print statement in the second page above raises a KeyError
because 'foo' is not a key in session_dict.

On a little further debugging, I discovered that the cookie.set(
'unr_session', sessionid ) call doesn't seem to work -- the cookie.get
function never seems to get the cookie back, it always looks like None.
This is no doubt a central aspect of the problem.

Does anyone know what's going on here?  What am I missing?
