MediaWiki 1.27.2[edit]

これは MediaWiki 1.27 ブランチのセキュリティおよび保守のリリースです。 ApiCreateAccount was removed in 1.27.0. It was incorrectly still marked as deprecated (rather than already removed) in the RELEASE-NOTES at the point 1.27.0 was released.

MediaWiki 1.27.1[edit]

これは MediaWiki 1.27 ブランチのセキュリティおよび保守のリリースです。

1.27.0 からの変更点[edit]

MediaWiki 1.27[edit]

PHP のバージョン要件[edit]

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

Configuration changes[edit]

新機能[edit]

  • $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 $wgLBFactoryConfManual:$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.
  • $wgAPIMaxLagThresholdManual:$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 $wgLocaltimezoneManual:$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.
  • $wgMaxUserDBWriteDurationManual:$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.
  • $wgCdnReboundPurgeDelayManual:$wgCdnReboundPurgeDelay was added to provide secondary delayed purges of URLs from CDN to mitigate DB replication lag and WAN cache purge lag.
  • (bug 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 $wgUseFilePatrolManual:$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 $wgGrantPermissionsManual:$wgGrantPermissions and $wgGrantPermissionGroupsManual:$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.
  • $wgContentHandlersManual:$wgContentHandlers now also supports callbacks to create an instance of the appropriate ContentHandler subclass.
  • Added $wgAuthenticationTokenVersionManual:$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.
  • (bug T33313) Add a preference for watching uploads by default, also applies to API-based upload tools.
  • $wgJpegPixelFormatManual:$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.
  • The file upload dialog (available if you install WikiEditor or VisualEditor) can now be configured using $wgUploadDialogManual:$wgUploadDialog.

Compatibility[edit]

MediaWiki 1.27 requires PHP 5.5.9 or later. There is experimental support for HHVM 3.6.5 or later.

MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but support for them is somewhat less mature. There is experimental support for Oracle and Microsoft SQL Server.

The supported versions are:

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

アップグレード[edit]

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.

Mailing list[edit]

A mailing list is available for MediaWiki user support and discussion:

      https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:

      https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes.

IRC help[edit]

There's usually someone online in #mediawiki on irc.freenode.net.
