How sessions work in MoinMoin
Sessions in MoinMoin are implemented using the authentication framework, see HelpOnAuthentication for more details. By default, the function MoinMoin.auth.moin_session is contained in the config.auth list and is responsible for managing sessions. You can use it together with any other authentication method if you need sessions.
As a programmer, in order to use session variables, you can use request.session like a dict, values stored there are automatically saved and restored if a session is available.
Code using the session framework currently includes:
the superuser "change user" functionality, see HelpOnSuperUser
- the visited pages trail
Anonymous sessions are supported by including the MoinMoin.auth.moin_anon_session function into config.auth and setting config.anonymous_cookie_lifetime. Cookies for anonymous sessions expire after config.anonymous_cookie_lifetime hours (can be fractional), however, the expiry is not verified. Saved state is removed earliest an hour after the session cookie has expired.
It is possible to replace moin_session in the auth configuration list. The new session handler should assign request.session based on a cookie or other information. The request.session object must be a dict-like object and it should implement session data expiry, cf. MoinMoin.auth.SessionData.
Session example code
Here's an example macro using the session code:
1 # -*- coding: iso-8859-1 -*- 2 3 """ 4 Tests session state. 5 """ 6 7 Dependencies = ['time'] 8 9 def execute(macro, args): 10 if 'test' in macro.request.session: 11 return macro.formatter.text(macro.request.session['test']) 12 import random 13 value = random.randint(1, 100000) 14 macro.request.session['test'] = value 15 return macro.formatter.text("set to value %d" % value)
