admin/delete_old_sessions. (there is also an admin/delete_old_revisions and admin/repair_references)
What is a "session" ?
wagn's current db structure:
mysql> show tables;
+-------------------------+
| Tables_in_en_copy |
+-------------------------+
| card_references |
| card_revisions |
| cards |
| schema_migrations |
| schema_migrations_cards |
| sessions |
| users |
+-------------------------+
7 rows in set (0.00 sec)
The first three are core and are there to stay. The others:
- schema_migrations: a rails table for tracking whether the db structure is up to date with the code
- schema_migrations_cards: a Wagn clone of the above for tracking whether card data is up to date with the code
- sessions: another Railsy table for handling session data. We don't store any real valuable information in a cookie; all we store is the session id, and we keep the real data in the table. See http://guides.rubyonrails.org/security.html#session-storage. The present ticket is about being able to empty out stale data from that table.
- users: a Wagn table, but one that will soon be integrated into cards.
So sessions refers to browser sessions, thx...
