MediaWiki 1.27

Exigence de version PHP

As of 1.27, MediaWiki now requires PHP 5.5.9 or higher (see Compatibility section). Additionally, the following PHP extensions are required:

  • ctype
  • iconv
  • json
  • mbstring (new requirement in 1.27)
  • xml

The following PHP extensions are strongly recommended:

  • openssl

Changements de configuration

  • $wgAllowMicrodataAttributes and $wgAllowRdfaAttributes were removed, now always enabled. If you use RDFa on your wiki, you now have to explicitly set $wgHtml5Version to 'HTML+RDFa 1.0' or 'XHTML+RDFa 1.0'.
  • $wgUseLinkNamespaceDBFields was removed.
  • Deprecated $wgResourceLoaderMinifierStatementsOnOwnLine and $wgResourceLoaderMinifierMaxLineLength , because there was little value in making the behavior configurable. The default values (`false` for the former, 1000 for the latter) are now hard-coded.
  • $wgDebugDumpSqlLength was removed (obsolète depuis v. 1.24).
  • $wgDebugDBTransactions was removed (obsolète depuis v. 1.20).
  • $wgUseXVO has been removed, as it provides functionality only used by custom Wikimedia patches against Squid 2.x that probably noone uses in production anymore. There is now $wgUseKeyHeader that provides similar functionality but instead of the MediaWiki-specific X-Vary-Options header, uses the draft Key header standard.
  • $wgScriptExtension (and support for '.php5' entry points) was removed. See the deprecation notice in the release notes for version 1.25 for advice on how to preserve support for '.php5' entry points via URL rewriting.
  • Password handling via the User object has been deprecated and partially removed, pending the future introduction of AuthManager. In particular:
    • expirePassword(), getPasswordExpireDate(), resetPasswordExpiration(), and getPasswordExpired() have been removed. They were unused outside of core.
    • The mPassword, mNewpassword, mNewpassTime, and mPasswordExpires fields are now private and will be removed in the future.
    • The getPassword() and getTemporaryPassword() methods now throw BadMethodCallException and will be removed in the future.
    • The ability to pass 'password' and 'newpassword' to createNew() has been removed. The only users of it seem to have been using it to set invalid passwords, and so shouldn't be greatly affected.
    • setPassword(), setInternalPassword(), and setNewpassword() have been deprecated, pending the introduction of AuthManager.
    • User::randomPassword() is deprecated in favor of a new method PasswordFactory::generateRandomPasswordString()
    • User::getPasswordFactory() is deprecated, callers should just create a PasswordFactory themselves.
    • A new constructor, User::newSystemUser(), has been added to simplify the creation of passwordless "system" users for logged actions.
  • $wgMaxSquidPurgeTitles was removed.
  • $wgAjaxWatch was removed. This is now enabled by default.
  • $wgUseInstantCommons now hotlinks Commons images by default instead of downloading originals and thumbnailing them locally. This allows wikis to save on CPU and bandwidth while reducing time to first byte for pages, even without a thumbnail handler. See $wgForeignFileRepos documentation for tweaks.
  • (bogue T27397) WebP is enabled by default as an uploadable filetype.
  • (bogue T48998) $wgArticlePath must now be either a full url, or start with a "/".
  • $wgRateLimitLog was removed; use $wgDebugLogGroups ['ratelimit'] instead.
  • Deprecated API formats dbg, txt, and yaml have been removed.
  • CLDRPluralRule* classes have been replaced with wikimedia/cldr-plural-rule-parser.
  • Removed $wgProfilePerHost , $wgUDPProfilerHost , $wgUDPProfilerPort , $wgUDPProfilerFormatString , $wgStatsMethod , $wgAggregateStatsID , $wgStatsFormatString , and $wgProfileCallTree (obsolète depuis v. 1.20).
  • For proper operation of LocalIdLookup with shared user tables, ensure that $wgSharedDB and $wgSharedTables are properly set even on the "central" wiki that all others are sharing from and that $wgLocalDatabases is set to the full list of sharing wikis on all those wikis.
  • Massive overhaul to session handling:
    • $wgSessionsInObjectCache is no longer supported and must be true, due to MediaWiki\Session\SessionManager. $wgSessionHandler is similarly no longer used.
    • ObjectCacheSessionHandler is removed, replaced with MediaWiki\Session\PhpSessionHandler.
    • PHP session handling in general ($_SESSION, session_id(), and so on) is deprecated. Use MediaWiki\Session\SessionManager instead. A new config variable, $wgPHPSessionHandling , is available to cause use of $_SESSION to issue a deprecation warning or to cause most PHP session handling to throw exceptions.
    • Deprecated UserSetCookies hook. Session-handling extensions should generally be creating a custom subclass of CookieSessionProvider. Other extensions messing with cookies can no longer count on user data being saved in cookies versus other methods.
    • Deprecated UserLoadFromSession hook, extensions should create a MediaWiki\Session\SessionProvider.
    • The User cannot be loaded from session until after Setup.php completes. Attempts to do so will be ignored and the User will remain unloaded.
    • CSRF tokens may be fetched from the MediaWiki\Session\Session, which uses the MediaWiki\Session\Token class.
  • MediaWiki will now auto-create users as necessary, removing the need for extensions to do so. An 'autocreateaccount' right is added to allow auto-creation when 'createaccount' is not granted to all users.
  • Deprecated AuthPluginAutoCreate hook in favor of LocalUserCreated.
  • Most cookie-handling methods in User are deprecated.
  • $wgAllowAsyncCopyUploads and $wgCopyUploadAsyncTimeout were removed. This was an experimental feature that has never worked.
  • Login and createaccount tokens now vary by timestamp.
  • LoginForm::getLoginToken() and LoginForm::getCreateaccountToken() return a MediaWiki\Session\Token, and tokens must be checked using that class's methods.
  • $wgEnotifUseJobQ was removed and the job queue is always used.
  • The functionality of the ApiSandbox extension has been merged into core. The extension should no longer be used.
  • $wgPreloadJavaScriptMwUtil was removed (obsolète depuis v. 1.26). Extensions, skins, gadgets and scripts that use the mediawiki.util module must express a dependency on it.
  • $wgIncludeLegacyJavaScript , deprecated in MediaWiki 1.26, now defaults false. Sites with extensions, skins, or gadgets that use the mediawiki.legacy.wikibits module should set this to true.
  • Removed configuration option $wgCopyrightIcon (obsolète depuis v. 1.18). Use $wgFooterIcons ['copyright']['copyright'] instead.
  • If the openssl and mcrypt PHP extensions are both unavailable, secure session storage (used for login) will raise an exception. This exception may be bypassed by setting $wgSessionInsecureSecrets = true.
  • Massive overhaul to authentication:
    • AuthPlugin and AuthPluginUser are deprecated.
    • LoginForm and associated templates are deprecated. Extensions which called static LoginForm methods should be converted into authentication providers.
    • The following hooks are deprecated:
      • AbortAutoAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
      • AbortLogin (create a MediaWiki\Auth\PreAuthenticationProvider instead)
      • AbortNewAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
      • AddNewAccount (use LocalUserCreated instead)
      • AuthPluginSetup (create a MediaWiki\Auth\PrimaryAuthenticationProvider instead)
      • ChangePasswordForm (use AuthChangeFormFields instead, or security levels)
      • LoginUserMigrated (create a MediaWiki\Auth\PreAuthenticationProvider instead)
      • UserCreateForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
      • UserLoginForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
    • The following hooks are removed:
      • AbortChangePassword
      • LoginPasswordResetMessage
      • PrefsPasswordAudit
    • The UserLoginComplete hook will no longer be called for all logins, only for those via the web UI. Use UserLoggedIn if you need to do something on all logins.
    • $wgRequirePasswordforEmailChange is removed.
  • $wgWellFormedXml has been removed.

Nouvelles fonctionnalités

  • $wgDataCenterUpdateStickTTL was also added. This decides how long a user sticks to the primary DC (via cookies) after they make changes to the site.
  • Added a new hook, 'UserMailerTransformContent', to transform the contents of an email. This is similar to the EmailUser hook but applies to all mail sent via UserMailer.
  • Added a new hook, 'UserMailerTransformMessage', to transform the contents of an emai after MIME encoding.
  • Added a new hook, 'UserMailerSplitTo', to control which users have to be emailed separately (ie. there is a single address in the To: field) so user-specific changes to the email can be applied safely.
  • $wgCdnMaxageLagged was added, which limits the CDN cache TTL when any load balancer uses a DB that is lagged beyond the 'max lag' setting in the relevant section of $wgLBFactoryConf .
  • User::newSystemUser() may be used to simplify the creation of passwordless "system" users for logged actions from scripts and extensions.
  • Extensions can now return detailed error information via the API when preventing user actions using 'getUserPermissionsErrors' and similar hooks by using ApiMessage instances instead of strings for the $result value.
  • $wgAPIMaxLagThreshold was added to limit bot changes when databases lag becomes too high.
  • Skins and extensions can now use FlexBox mixins (.flex-display(@display: flex) and .flex(@grow: 1, @shrink: 1, @width: auto, @order: 1)) in Less to create cross-browser-compatible FlexBox rules. Users will still need to add fallback float rules or the like for compatibility with IE9- separately.
  • Added MWTimestamp::getTimezoneString() which returns the localized timezone string, if available. To localize this string, see the comments of $wgLocaltimezone in includes/DefaultSettings.php.
  • Added CentralIdLookup, a service that allows extensions needing a concept of "central" users to get that without having to know about specific central authentication extensions.
  • $wgMaxUserDBWriteDuration added to limit huge user-generated transactions. Regular web request transactions that takes longer than this are aborted.
  • Added a new hook, 'TitleMoveCompleting', which runs before a page move is committed.
  • $wgCdnReboundPurgeDelay was added to provide secondary delayed purges of URLs from CDN to mitigate DB replication lag and WAN cache purge lag.
  • (bogue T49162) Installer will default to setting CACHE_ACCEL as the main cache type if it is available.
  • It is now possible to patrol file uploads (both for new files and new versions of existing files). Special:NewFiles has gained an option to filter by patrol status. This functionality can be disabled using $wgUseFilePatrol .
  • MediaWiki\Session infrastructure allows for easier use of session mechanisms other than the usual cookies.
    • SessionMetadata and SessionCheckInfo hooks allow for setting and checking custom session metadata.
  • Added MWGrants and associated configuration settings $wgGrantPermissions and $wgGrantPermissionGroups to hold configuration for authentication features such as OAuth that want to allow restricting the user rights a user may make use of.
  • Added MWRestrictions as a class to check restrictions on a WebRequest, e.g. to assert that the request comes from a particular IP range.
  • Added bot passwords, a rights-restricted login mechanism for API-using bots.
  • Whitelisted the following HTML attributes for all elements in wikitext: aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
  • Removed "presentation" restriction on the HTML role attribute in wikitext. All values are now allowed for the role attribute.
  • $wgContentHandlers now also supports callbacks to create an instance of the appropriate ContentHandler subclass.
  • Added $wgAuthenticationTokenVersion , which if non-null prevents the user_token database field from being exposed in cookies. Setting this would be a good idea, but will log out all current sessions.
  • $wgEventRelayerConfig was added, for managing PubSub event relay configuration, specifically for reliable CDN url purges.
  • Requests have unique IDs, equal to the UNIQUE_ID environment variable (when MediaWiki is behind Apache+mod_unique_id or something similar) or a randomly- generated 24-character string. This request ID is used to annotate log records and error messages. It is available client-side via mw.config.get( 'wgRequestId' ). The request ID supplants exception IDs. Accordingly, MWExceptionHandler::getLogId() is deprecated.
  • (bogue T33313) Add a preference for watching uploads by default, also applies to API-based upload tools.
  • $wgJpegPixelFormat was added to override chroma subsampling for JPEG image thumbnails created via ImageMagick. Defaults to 'yuv420', providing bandwidth savings versus the previous behavior on many files.
  • MediaWiki\Auth infrastructure (called "AuthManager") allows for more flexible configuration of multiple authentication pieces that was possible with AuthPlugin. For example, it's now easy to plug in second-factor authentication, or add additional checks to the login process, or to support multiple login methods at once, or to support non-password-based login methods.
    • Providers are configured via the global setting $wgAuthManagerConfig .
    • New hook, AuthChangeFormFields, to adjust the form fields on AuthManager-related special pages.
    • New hook, AuthManagerLoginAuthenticateAudit, for additional logging of AuthManager-related authentication requests.
    • New hook, ChangeAuthenticationDataAudit, for additional logging of AuthManager-related authentication data changes.
    • New hook, SecuritySensitiveOperationStatus, to work with the new mechanism for requiring a recent login before taking security-sensitive operations like changing a password.
    • Two new globals, $wgChangeCredentialsBlacklist and $wgRemoveCredentialsBlacklist can be used to prevent the web UI and the API changing certain authentication data.
  • The file upload dialog (available if you install WikiEditor or VisualEditor) can now be configured using $wgUploadDialog .

MediaWiki 1.27 nécessite PHP 5.5.9+ . Il y a un support expérimental pour HHVM 3.6.5 ou ultérieur.

Le SGBD recommandé pour MediaWiki est MySQL. PostgreSQL ou SQLite peuvent aussi être utilisés mais leur support est nettement moins abouti. Il existe un support expérimental pour Oracle et Microsoft SQL Server.

Les versions supportées sont :

  • MySQL 5.0.3+
  • PostgreSQL 8.3+
  • SQLite 3.3.7+
  • Oracle 9.0.1+
  • Microsoft SQL Server 2005 (9.00.1399)

Mise à jour

1.27 has several database changes since 1.26, and will not work without schema updates. Note that due to changes to some very large tables like the revision table, the schema update may take quite long (minutes on a medium sized site, many hours on a large site).

If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed with MediaWiki 1.21.

Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

For notes on 1.26.x and older releases, see HISTORY.
