-SCHEMA.DOC
-
The most up-to-date schema for the tables in the database
-should always be "tables.sql" in the maintenance directory,
-which is called from the installation script. Here are a
-few highlights that may be out of date:
-
-user (MediaWiki users)
-
- user_id
- integer, primary key, autoincrement
- user_name
- Usernames must be unique, must not be in the form of
- an IP address. _Shouldn't_ allow slashes or case
- conflicts. Spaces are allowed, and are _not_ converted
- to underscores like titles. (Conflicts?)
- user_password
- Hash of current password.
- user_newpassword
- Generated for mail-a-new-password feature
- user_email
- Note -- email should be restricted, not public info.
- Same with passwords. ;)
- user_options
- Newline-separated list of name=value pairs.
- user_token
- A pseudorandomly generated value that is stored in
- a cookie when the "remember password" feature is
- used (previously, a hash of the password was used, but
