MediaWiki 1.39.0-rc.0

[edit]

Upgrading notes for 1.39

[edit]

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

See the file UPGRADE for more detailed per-version upgrade instructions from the oldest supported upgrading version, MediaWiki 1.31.

Some specific notes for MediaWiki 1.39 upgrades are below:

  • (task T278139) Drop PHP 7.3 support in MediaWiki 1.39; require 7.4.3 or higher.

For notes on 1.38.x and older releases, see HISTORY.

Configuration changes for system administrators in 1.39

[edit]
  • The default serialization method for file meta-data has been changed to JSON. You can revert it to PHP by setting the 'useJsonMetadata' property to false in $wgLocalFileRepo .
  • The DBO_SSL flag in $wgDBservers and $wgLBFactoryConf has been deprecated in favour of a boolean "ssl" parameter.
  • $wgMangleFlashPolicy is deprecated and is no longer functional. Users who are somehow still using Flash as a browser extension will be exposed to CSRF vulnerabilities.

New configuration

[edit]
  • $wgAutoCreateTempUser – configures automatic user creation on page save.
  • $wgCopyUploadAllowOnWikiDomainConfig – Configures if administrators can use the MediaWiki:Copyupload-allowed-domains system message to define which domains can be used with the upload-by-url tool.
  • $wgLBFactoryConf['configCallback'] can be set to a callback function that returns an array with keys to update in $wgLBFactoryConf . This can be used to update the database configuration on the fly, e.g. to take replica hosts out of rotation.
  • $wgCdnMatchParameterOrder can be set to false if MediaWiki is behind a CDN that re-orders query parameters. This will make the code that matches request URLs to canonical CDN URLs insensitive to parameter order.
  • $wgMultiShardSiteStats – split site_stats across multiple rows. Only useful for very large, heavily edited wikis. (task T306589)
  • $wgPrivilegedGroups – Users belonging in some of the listed groups will be audited more aggressively.

Changed configuration

Removed configuration

New user-facing features in 1.39

[edit]
  • Optional automatic user creation on page save ($wgAutoCreateTempUser )
  • Administrators now have the option to delete/undelete the associated "Talk" page when they are (un)deleting a given page. `deletetalk` and `undeletetalk` options were added to the 'delete' and 'undelete' action APIs in MW 1.38.
  • `=` is now a wikitext built-in magic word, expanding to `=`. This is conventionally used as an escape mechanism to allow the use of `=` in unnamed template arguments. Defining Template:= to expand to something other than `=` has been deprecated since 1.36, with affected pages put into a special tracking category for migration.
  • (task T284020) Bot passwords are now supported when using the REST API.

New developer features in 1.39

[edit]
  • Added optional $size param to SearchResultProvideThumbnail hook.
  • SearchResultProvideThumbnail hook interface moved from MediaWiki\Rest\Hook namespace to MediaWiki\Search\Hook.
  • JsonValidateSaveHook has been added to allow extensions to set additional pre-save validations for specific JSON pages (task T313254).
  • Added 'PermissionErrorAudit' hook, enabling extensions to audit permission errors on specfic actions (for instance, account registration failed attempts due to a block (task T306018)).

Languages updated in 1.39

[edit]

MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Phabricator reports.

  • Actual localization was added for several languages, which were already in Names.php and even used for a Wikipedia:
    • (task T313200) Added language support for Rundi (Kirundi, rn).
    • (task T310976) Added language support for Tumbuka (ChiTumbuka, tum).
    • (task T314270) Added language support for Kanuri (kr).

The old name of the "File" namespace was "Picha", which has been kept for backwards compatibility. If you manage a wiki in Swahili, and you use "Faili:" as a namespace anywhere in wikitext, and you mean to use it as "Media:", these need to be replaced to "Media:".
  • (task T309866) Some namespace translations were updated for Kyrgyz (ky). The old ones are retained as aliases for backwards compatibility.

  • Instantiating HTMLCacheUpdate class, deprecated in 1.34, now emits deprecation warnings.
  • ISQLPlatform::tableNames() (implemented by IDatabase) is soft deprecated. None of the tableName*() functions should be used by most users; if you absolutely must use raw SQL, write several tableName() calls instead.
  • Language::isWellFormedLanguageTag() has been deprecated in favor of LanguageCode::isWellFormedLanguageTag().
  • The PrevNextNavigationRenderer helper class has been deprecated in favor of the new PagerNavigationBuilder one.
  • The methods IndexPager::getPagingLinks(), IndexPager::getLimitLinks() and IndexPager::buildPrevNextNavigation() have been deprecated in favor of IndexPager::getNavigationBuilder().
  • Overriding the method IndexPager::makeLink() has been deprecated.

Other changes in 1.39

[edit]
  • Dynamic default values are now applied before extension registration callbacks are run. This way, extensions have a complete view of config variables, with all defaults applied. For example, when the default value of X used to be static but becomes dynamic, and an extension reads the value of X in the registration callback, it will now continue to function as expected. In some cases however, this may cause an undesired change in behavior: if the dynamic default of setting X depends on the value of setting Y, and an extension changes Y, the changed value of Y will no longer affect the value of X.
