Upgrading notes for 1.42

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 1.35.

Some specific notes for MediaWiki 1.42 upgrades are below:

  • MediaWiki now requires Composer 2.x, and any related (vendor) files generated by Composer must be generated by Composer 2.x. Composer 1.x is mostly end-of-life upstream, and using it will result in slower actions when downloading and installing packages. See the upstream blog post at https://blog.packagist.com/deprecating-composer-1-support/ for further information.

For notes on 1.41.x and older releases, see HISTORY.

Configuration changes for system administrators in 1.42

edit
  • Composer 1.x is no longer supported and cannot be used with MediaWiki.

New user-facing features in 1.42

edit
  • (phab:T308160) filter: is now allowed in inline CSS in wikitext

New developer features in 1.42

edit
  • (phab:T326466) MediaWikiIntegrationTestCase's database and set-up code now avoids using dynamic properties, which was causing deprecation warnings in PHP 8.2.
  • (phab:T13555) MediaWiki now includes styles that allow more accessible markup for section headings. MediaWiki's own HTML output will be changed in the future. More information: https://www.mediawiki.org/wiki/Heading_HTML_changes
  • (phab:T193472) PHP Notice and Warning errors that are silenced (e.g., by the "@" operator, error_reporting directive, or Wikimedia\AtEase) are now logged to a new "silenced-error" channel.
  • (phab:T347347) The CLI installer accepts a "--with-developmentsettings" argument to require the DevelopmentSettings.php file at install time.
  • (phab:T350054) MediaWiki's ResourceLoader has been updated to add basic support for code-splitting (aka "tree-shaking") when using the Codex component library. A ResourceLoader module can now specify a list of "codexComponents" in its module definition and ensure that only the code for those components gets sent to the client. More information: https://www.mediawiki.org/wiki/Codex#Subset_of_components
  • (phab:T345185) The SessionProviderInterface now allows defining providers that are exempt from rights checks when auto-creating users.

Breaking changes in 1.42

edit
  • (phab:T340802) ResourceLoader: The target system is no longer active; all modules will load on all platforms even if they are marked as desktop- or mobile-only in the 'targets' field, which is no longer read. As part of this, the internal methods RL\Module::setTarget() & ::getTargets(), and OutputPage::setTarget() have been removed.
  • TitleArray, deprecated since 1.41, has been removed.
  • UserRightsProxy, deprecated since 1.38, has been removed.
  • SiteConfiguration::getConfig(), deprecated in 1.41, has been removed.
  • UserLoginCompleteHook is always called with its $direct parameter set to boolean true. The false case has been removed.
  • MagicWord::load() has been marked @internal and may change without further notice.
  • All classes that implemented the IDBAccessObject interface and all interfaces that extended it no longer do that. See https://w.wiki/9DAX for more info.
  • BagOStuff::setNewPreparedValues() now emits deprecation warnings.
  • The type of the last parameter of BeforeInitializeHook::onBeforeInitialize and MediaWikiPerformActionHook::onMediaWikiPerformAction changed from MediaWiki to ActionEntryPoint. Relevant methods are still available on the object.
  • Classes overruling Maintenance::finalSetup() must now declare the $settings parameter and pass it on when calling the parent implementation. MaintenanceRunner will always provide this parameter when calling finalSetup().
  • WebResponse::disableForPostSend() is no longer static.
  • MediaWiki's virtual REST internal library has been removed in favor of an HTTP library like Guzzle, MultiHttpClient, or MwHttpRequest.
  • Several deprecated methods have been removed from the Content interface in favor of the respective methods in ContentHandlers. Callers should use a more narrow interface like ContentRenderer or ContentTransformer when possible. The following methods have been removed from the Content class:
    • getParserOutput()
    • preSaveTransform()
    • preloadTransform()
    • prepareSave()
  • User::blockedFor() and AbstractBlock::getReason(), deprecated in 1.35, have been removed. Use AbstractBlock::getReasonComment() instead.
  • SerializedValueContainer::newUnified(), deprecated in 1.41, has been removed.
  • Use of ActorMigration for any of the following tables, deprecated since 1.34, is no longer supported:
  • ParserOutput::setFlag() and ::getFlag(), deprecated in 1.38, were removed. You should use ::setOutputFlag() and ::getOutputFlag() instead.
  • ParserOutput::getCategories(), deprecated in 1.40, has been removed. You should use ::getCategoryNames() and ::getCategorySortKey() instead.
  • ParserOutput::getTOCHTML(), deprecated in 1.40, has been removed. You should use ::getTOCData() instead.
  • The parser does not substitute the default category sort key at parse time; this is substituted when the category links table is updated instead. As a result {{DEFAULTSORT}} will affect all the contents of the page (not just categories added after the location of {{DEFAULTSORT}} in the article) and ParserOutput::getCategorySortKey() will return the empty string (still meaning "use the default sort key") instead of the immediate value of {{DEFAULTSORT}}. ParserOutput::getCategorySortKey() will directly reflect the category link contents, instead of having postprocessing done to it (character references decoded, newlines replaced, language conversion). That postprocessing is now done when the category links table is updated, and so it consistently applies even when categories are added directly via API.
  • PostgresUpdater::addPgEnumValue(), unused everywhere, has been removed without deprecation. Use of ENUM is highly discouraged.
  • ILoadBalancer::getAnyOpenConnection() has been removed without deprecation, use ::getConnection() instead.
  • The unused method CommentStore::getFields() has been removed without depreaction.
  • LanguageConverter's internal properties, all deprecated in 1.35 or 1.36, have now had their deprecated property accessors dropped:
    • mConvRuleTitle
    • mUserVariant
    • mHeaderVariant
    • mMaxDepth
    • mVarSeparatorPattern
    • mLangObj
    • mTablesLoaded
    • mTables
    • mVariants
    • mMainLanguageCode
    • mVariantFallbacks
    • mFlags
    • mVariantNames
    • mDescCodeSep
    • mDescVarSep
  • OutputPage::addParserOutputText has been marked @internal since there are no known users of it. Its old behavior has been deprecated and will change in the future without further notice.
  • Some methods of ConnectionManager and SessionConsistentConnectionManager, previously deprecated, have been removed:
    • ::releaseConnection(), deprecated in 1.38; do not use
    • ::getWriteConnectionRef(), deprecated in 1.39; use getWriteConnection()
    • ::getReadConnectionRef(), deprecated in 1.38; use getReadConnection()
    • ::getLazyWriteConnectionRef(), deprecated in 1.39; use getWriteConnection()
    • ::getLazyReadConnectionRef(), deprecated in 1.38; use getReadConnection()
  • CoreParserFunctions::mwnamespace(), deprecated in 1.39, has been removed. Use CoreParserFunctions::namespace() instead.
  • Processor:: and ExtensionProcessor::getExtraAutoloaderPaths(), deprecated in 1.39, have been removed; use ::getExtractedAutoloadInfo() instead.
  • MWExceptionHandler::rollbackMasterChangesAndLog(), deprecated in 1.37, has been removed. Use ::rollbackPrimaryChangesAndLog() instead.
  • Passing a custom database connection to DatabaseBlockStore::insertBlock(), deprecated since 1.41, is no longer supported.
  • LanguageConverterFactory::isTitleConversionDisabled(), deprecated in 1.36, has been removed. Use ::isLinkConversionDisabled() instead.
  • MediaWikiIntegrationTestCase::$tablesUsed has been deprecated. The framework now detects these automatically.
  • Passing an actor ID to the constructor of UserIdentityValue, deprecated since 1.36, is no longer being supported.
  • Support for setting dynamic property on StatusValue object has been removed. To pass your arbitrary data along the object, use StatusValue::statusData property (which is always declared).
  • The global function wfReportTime(), deprecated since 1.40, has been removed.
  • The skin template parameter 'reporttime', deprecated since 1.41, has been removed.
  • WikiPage::getPageIsRedirectField(), deprecated since 1.41, has been removed.
  • WikiPage::insertRedirect(), deprecated since 1.41, has been removed.
  • Several methods in PageArchive, all deprecated in 1.38, have been removed:
    • ::listRevisions()
    • ::getRevisionRecordByTimestamp()
    • ::getArchivedRevisionRecord()
    • ::getPreviousRevisionRecord()
    • ::getLastRevisionId()
    • ::isDeleted()
    • ::getFileStatus()
    • ::getRevisionStatus()
  • Database, DatabaseInstaller, DatabaseUpdater, DBPrimaryPos, ResultWrapper and SQLPlatform are no longer stable to extend. It is not possible to define database types in an extension.
  • UserDef::PARAM_ALLOWED_USER_TYPES now differentiates between temporary account usernames and user accounts. Any endpoints that want temp users to be valid but were passing a name through will break. Temp users must now be explicitly allowed.
  • The Hooks class, a legacy wrapper for HooksContainer, has been removed. All of its contents have been previously deprecated in 1.35 (or 1.41 for ::runner()):
    • ::register()
    • ::clear(),
    • ::isRegistered()
    • ::getHandlers()
    • ::run()
    • ::runWithoutAbort()
    • ::runner()
  • Article::__get(), ::__set(), deprecated since 1.35, have been removed.
  • Several API calls have been updated to return a 'temp' user flag:
    • ApiQueryImageInfo
    • ApiQueryLogEvents
    • ApiQueryRecentChanges
    • APIs extended from ApiQueryRevisionsBase
  • Parser::getCustomDefaultSort() and ::setDefaultSort(), deprecated since 1.38, have been removed.
  • UserOptionsLookup::getDefaultOptions() and UserOptionsLookup::getDefaultOption() now accept an UserIdentity, to take conditional defaults for user properties into account. When conditional defaults are used, calling those methods without the UserIdentity might produce unexpected results.
  • Installer related classes have been namespaced without having aliases added. The following have been moved to MediaWiki\Installer:
    • CliInstaller
    • DatabaseInstaller
    • InstallDocFormatter
    • Installer
    • InstallerOverrides
    • InstallerSessionProvider
    • LocalSettingsGenerator
    • MysqlInstaller

  • The no-op module es6-polyfills (deprecated as of 1.41) has been removed.
  • Log formatters (as defined in $wgLogActionsHandlers) are now created by ObjectFactory, which means their constructors must be public. Legacy log formatters using callbacks instead of class names are no longer supported.

Deprecations in 1.42

edit

  • (phab:T166010) All PHP code in MediaWiki is slowly being moved to be in a class namespace as appropriate, so that we can use PSR-4 auto-loading, which will speed up general code loading of MediaWiki. The old global namespace class names are being left behind as deprecated aliases.
