[edit] Fields
- Some of this information was adapted from
schema.docin the MediaWikidocs/directory.
[edit] user_password
- user_password is one of two formats, depending on the setting of $wgPasswordSalt:
- -If $wgPasswordSalt is true (default) it is a concatenation of:
- The string ":B:",
- A pseudo-random hexadecimal 31-bit salt between 0x0 and 0x7fff ffff (inclusive),
- The colon character (":"), and
- The MD5 hash of a concatenation of the salt, a dash ("-"), and the MD5 hash of the password.
- -If $wgPasswordSalt is false, it is a concatenation of:
- The string ":A:" and
- The MD5 hash of the password.
[edit] user_editcount
user_editcount
- Count of edits and edit-like actions.
- *NOT* intended to be an accurate copy of COUNT(*) WHERE rev_user=user_id May contain NULL for old accounts if batch-update scripts haven't been run, as well as listing deleted edits and other myriad ways it could be out of sync.
- Meant primarily for heuristic checks to give an impression of whether the account has been used much.
[edit] user_id
- user_id is the primary key, used to uniquely identify a user
[edit] user_name
- user_name: Usernames must be unique, and 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?)
[edit] user_real_name
- user_real_name stores the user's real name (optional) as provided by the user in their "Preferences" section.
[edit] user_newpassword
- user_newpassword is generated for the mail-a-new-password feature.
[edit] user_email
- user_email Note: email should be restricted, not public info. Same with passwords. ;)
[edit] user_options
- user_options is no longer used as of MediaWiki 1.16. See manual:User properties table
- On older versions of mediawiki, it is a newline-separated list of name=value pairs of the information of special:preferences. Old user accounts who haven't logged in since the field stopped being used may still have this field set.
[edit] user_touched
- user_touched the last time a user made a change on the site, including logins, changes to pages (any namespace), watchlistings, and preference changes.
[edit] user_token
- user_token a pseudorandomly generated value that is stored in a cookie when the "remember password" feature is used
