Manual:Conteúdos Disposição da base de dados do MediaWiki Tabela das user

A tabela user é onde o MediaWiki guarda a informação sobres os utilizadores. Se utilizar Postgres, esta tabela é chamada de mwuser.

Campos

Alguma desta informação foi adaptada de schema.doc na diretoria docs/ do MediaWiki.

user_id

user_id é a chave principal, utilizada para identificar exclusivamente um utilizador

user_name

user_name: Os nomes de utilizador devem ser únicos, e não devem estar na forma de um endereço de IP. Não se deve permitir barras ou conflitos de casos. Consulte também Manual:$wgInvalidUsernameCharacters . Spaces are allowed, and underscores are converted to spaces (the opposite than with page names).

user_real_name

Versão MediaWiki:
1.3

user_real_name stores the user's real name (optional) as provided by the user in their "Preferences" section.

user_password

user_password is one of three formats, depending on the setting of $wgPasswordDefault :

  • Since MediaWiki 1.24, $wgPasswordDefault defaults to pbkdf2.

In this case you will get a concatenation of the following:

    • A string ":pbkdf2:".
    • The hashing algorithm used inside the pbkdf2 layer, by default "sha512".
    • The colon character (:).
    • The cost for this algorithm, by default "30000".
    • The colon character (:).
    • The length of the derived key; "64" by default.
    • The colon character (:).
    • Base64 encoded salt of the hashing algorithm, e.g. "kkdejKlBYFV7+LP2m2thYA=="
    • The colon character (:).
    • And finally the base64 encoded result of the hashing algorithm (that had a (default) length of 128 bytes before base64 encoding).

The hash of the plain text user password.

  • Since MediaWiki 1.24, if the maintenance script wrapOldPasswords.php has been used, passwords may also start with ":pbkdf2-legacyA:" or ":pbkdf2-legacyB:" like ":pbkdf2-legacyB:!sha256:10000:128!...".
  • For passwords written by MediaWiki 1.23 and older, if $wgPasswordSalt was true (default) it is a concatenation of the following:
    • The string ":B:"
    • A pseudo-random hexadecimal 31-bit salt between 0x0 and 0x7fff ffff (inclusive)
    • The colon character (:)
    • The MD5 hash of a concatenation of the salt, a dash ("-"), and the MD5 hash of the password.
  • For passwords written by MediaWiki 1.23 and older, if $wgPasswordSalt was false, it is a concatenation of the following:
    • The string ":A:"
    • The MD5 hash of the password.

user_newpassword

user_newpassword is generated for the mail-a-new-password feature.

user_newpass_time

user_newpass_time is set to the current timestamp (wfTimestampNow()) when a new password is set. Like the other timestamps, it is in MediaWiki's timestamp format (yyyymmddhhmmss, e.g. 20130824025644).

user_email

Email should be restricted, not public info. Same with passwords. Enter details at your own risk. ;)
This field is not nullable, so users who have never supplied an email address have an empty string set.

user_options

Versão MediaWiki:
1.18

user_options is no longer used as of MediaWiki 1.16. Consulte Manual:Tabela das Propriedades do utilizador (user_properties) .

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.

user_touched

user_touched the last time a user logged in (not just mere visiting using an existing session), modified user settings, or got promoted into new user groups.

user_token

Versão MediaWiki:
1.4

user_token is a pseudorandomly generated value. When a user checks "Manter-me autenticado" the value is stored in a persistent browser cookie ${wgCookiePrefix}Token that authenticates the user while being resistant to spoofing.

user_email_authenticated

user_email_authenticated is the timestamp of when the user email was authenticated. Predefine para NULL.

user_email_token

Versão MediaWiki:
1.5

user_email_token is a token used for confirming an email address. See User::newFromConfirmationCode in User.php

user_email_token_expires

user_email_token_expires is the expiration timestamp of the email token.

user_registration

Versão MediaWiki:
1.6

user_registration is the timestamp (date and time) of when the user registered. For old users, they may have a value of NULL for this field. The fixUserRegistration.php script can be used to back-populate this field.

user_editcount

Versão MediaWiki:
1.9

user_editcount is the rough number of edits and edit-like actions the user has performed. The following actions are counted as edits:

  • Creating or modifying a MediaWiki page even if the revision or page is later deleted (i.e. making a non-null edit)

This field is not an exactly accurate copy of COUNT(*) FROM revision WHERE rev_user = user_id. However, it should be roughly accurate if the update scripts are consistently run and it's the only place edit count data is available to the software, so it's still used for serious purposes like deciding whether accounts have been autopromoted.

A number of things could cause this value to be incorrect. For example, it may be out of date or, for old accounts, NULL if the update script (initEditCount.php ) hasn't been run. Also, some deletions may not affect it consistently.

user_emailauthenticationtimestamp

Versão MediaWiki:
1.3

Removido na versão v1.4.

user_password_expires

Versão MediaWiki:
1.23

Date when user's password expires; null for no expiration date.

user_is_temp

Versão MediaWiki:
1.41
Gerrit change 918513

A boolean value representing whether the user is a temporary user. Zero if any type of user other than a temporary user. This exists to allow temporary users to be identified from the database only, by external applications.
