MediaWiki 1.24
MediaWiki 1.24.0 est la branche stable et est recommandé pour une utilisation en production.

MediaWiki 1.24 est une mise à jour majeure qui contient de nouvelles fonctionnalités ainsi que des corrections de bogues. Voici une liste exhaustive des changements liés à cette version (en anglais).

Nos remerciements à tous ceux qui nous ont aidé à améliorer MediaWiki en effectuant des batteries de tests sur la version bêta et qui nous ont soumis les rapports de bogues.

Changements de configuration

 * MediaWiki will no longer run if register_globals is enabled. It has been deprecated for 5 years now, and was removed in PHP 5.4. For more information about why, see .
 * MediaWiki now requires PHP's iconv extension. openSUSE users may need to install the php5-iconv package. Users of other systems may need to add extension=iconv.so to php.ini or recompile PHP without --without-iconv.
 * MediaWiki will no longer function if magic quotes are enabled. It has been deprecated for 5 years now, and was removed in PHP 5.4.
 * The server's canonical hostname is available as $wgServerName, which is exposed in both mw.config and ApiQuerySiteInfo.
 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch, for using the old schema of the page_props table, in case the respective schema update was not applied.
 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything' user option was removed. Use $wgNamespacesToBeSearchedDefault instead or if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
 * $wgMasterWaitTimeout has been deprecated.
 * $wgDBClusterTimeout has been removed.
 * $wgProxyKey has been removed. It is no longer used by MediaWiki core. Ensure $wgSecretKey is set in LocalSettings.php.
 * $wgExtraInterlanguageLinkPrefixes is a new configuration variable that contains an array of interwiki prefixes that should be treated as language prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set to true).
 * $wgParserTestRemote has been removed.
 * $wgCountTotalSearchHits has been removed. If you're concerned about efficiency of search, you should use something like CirrusSearch instead of built in search.
 * Users in the 'sysop' group have access to Special:MergeHistory by default.
 * $wgFileStore was removed after having been deprecated in 1.17. Alternative configurations are $wgDeletedDirectory and $wgHashedUploadDirectory.
 * The deprecated $wgUseCommaCount variable has been removed.
 * $wgEnableSorbs and $wgSorbsUrl have been removed.
 * The UserCryptPassword and UserComparePasswords hooks are no longer called. Any extensions using them must be updated to use the Password Hashing API.
 * $wgCompiledFiles has been removed.
 * $wgSortSpecialPages was removed, the listing on Special:SpecialPages is now always sorted.
 * $wgHTCPMulticastAddress, $wgHTCPMulticastRouting and $wgHTCPPort were removed.
 * $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort and $wgRC2UDPPrefix have been removed.
 * The default password type for MediaWiki has been changed from MD5 to PBKDF2. Password hashes will automatically be updated as users log in. If necessary, the old MD5 hashing can be restored by changing $wgPasswordDefault to 'B'. In addition, there is a maintenance script wrapOldPasswords.php that can wrap all passwords in PBKDF2 (or the hashing algorithm of your choice) if you don't want to wait for your users to log in.
 * $wgImportSources can now either be a regular array, or an associative map specifying subprojects on the interwiki map of the target wiki, or a mix of the two. Existing configurations will still work.
 * Users must be able to edit through a page's protection to be able to delete it.
 * The default thumb size ($wgDefaultUserOptions['thumbsize']) is now 300px, up from 180px. If you have altered the number of entries in $wgThumbLimits for your wiki, you may need to adjust your default user settings to compensate for the index change.
 * $wgDeferredUpdateList is now deprecated, you should use DeferredUpdates::addUpdate instead.
 * $wgCanonicalLanguageLinks has been removed. Per Google recommendations, we will not send a rel=canonical pointing to a variant-neutral page, however we will send rel=alternate.

Nouvelles fonctionnalités

 * Added new hook WatchlistEditorBeforeFormRender, allowing subscribers to manipulate the list of pages and/or preload lots of data at once.
 * Added new argument &$link in hook WatchlistEditorBuildRemoveLine, allowing the link to the title to be changed.
 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate WhatLinksHere entries.
 * Added a new hook, "ContentGetParserOutput", to customize parser output for a given content object.
 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
 * HTMLForm's HTMLTextField now supports the 'url' type.
 * HTMLForm fields may now be dynamically hidden based on the values of other fields in the form.
 * HTMLForm now supports multiple copies of an input field or set of input fields, e.g. the form may request "one or more usernames" without having to have the user enter delimited list of names into a text field.
 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of the sidebar just before its display.
 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps jquery.cookie so that getting/setting a cookie is syntactically and functionally similar to using the WebRequest::getCookie and WebResponse::setcookie methods.
 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option, $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions and gadgets use the long-deprecated functions that were removed in jQuery 1.9. This option is turned off by default, and will be removed in MediaWiki 1.25.
 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
 * Changes to content typography (fonts, etc.). See https://www.mediawiki.org/wiki/Typography_refresh for further information.
 * WikitextContent will now render redirects with the expected "redirect" header, rather than as an ordered list. Code calling Article::viewRedirect can probably be changed to no longer special-case redirects.
 * Header font set to a serif font stack. See https://www.mediawiki.org/wiki/Typography_refresh for further information.
 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This is only for page views, since this hook doesn't affect UserLogin, OAuth, CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to overall design of the system.
 * (bug 17367) It is now possible to add pages to your watchlist from Special:UnwatchedPages without reloading the special page.
 * New methods setVolatile and isVolatile are added to PPFrame, so that extensions such as Cite.php can mark that their output is volatile and shouldn't be cached.
 * (bug 52817) Advanced search options are now saved on the search page itself, rather than in a dedicated pane in the preferences panel.
 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in the Vector skin has gained a label that should make it more discoverable.
 * MWCryptHKDF added for fast, cryptographically secure random number generation that won't deplete openssl's entropy pool.
 * ResourceLoader: File modules can now provide a skip function that uses an inline feature test to bypass loading of the module.
 * (bug 20210) Special pages may now provide autocompletion of their subpage names in search suggestions. Right now the only useful implementation is in Special:Log, but more are to come.
 * Special:MostLinkedTemplates is no longer limited to transclusions from the Template namespace.
 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules. This works the same as 'remoteExtPath' but is relative to the skins/ folder instead of the extensions/ folder.
 * Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods. Exposed as module "json" with a skip function to optimise loading.
 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition to 'name', to allow for the name to be localizable. 'name' should still be specified for backwards-compatibility and to define the path Special:Version uses to find extension license information.
 * Browser tests are now included to verify basic wiki functionality in developer environments. For details on running tests, see tests/browser/README.mediawiki.
 * Upgrade jStorage to v0.4.10.
 * | is now a magic word that produces the | character. This removes the need for Template:! for purposes such as passing pipes inside of parameters.
 * (bug 20790) The block log snippet on Special:Contributions and while editing user and user talk pages now works for IP range blocks.
 * (bug 9360) Added ability to change the page language for MediaWiki pages using Special:PageLanguage. All pages are set to wiki language by default. The feature needs to be enabled with $wgPageLanguageUseDB=true and permission needs to be set for 'pagelang'.
 * Upgrade Moment.js to v2.8.3.
 * (bug 67042) Added support for the HTML5 tag for East Asian typography.
 * Upgrade Sinon.JS to 1.10.3.
 * Added the es5-shim polyfill for older or non-compliant javascript engines.
 * Upgrade jQuery Cookie to v1.3.1.
 * (bug 20476) Add a "viewsuppressed" user right to be able to view suppressed content but not suppress it ("suppressrevision" right).
 * (bug 66440) The MediaWiki web installer will now allow you to choose the skins to enable (from the ones included in download tarball) and decide which one should be the default.
 * (bug 68085, 68802) Links like localInterwikiPrefix:languageCode:pageTitle, where localInterwikiPrefix is a member of the $wgLocalInterwikis array, will no longer be displayed in the sidebar when $wgInterwikiMagic is true. In a similar way, links like localInterwikiPrefix:File:Image.png and localInterwikiPrefix:Category:Hello will now render as regular links, and will not include the file or add the page to the category.
 * New special page, MyLanguages, to redirect users to subpages with localised versions of a page. (Integrated from Extension:Translate)
 * MediaWiki now supports multiple password types, including bcrypt and PBKDF2. The default type can be changed with $wgPasswordDefault and the type configurations can be changed with $wgPasswordConfig.
 * Skins can now define custom styles for default ResourceLoader modules using the $wgResourceModuleSkinStyles global. See the Vector skin for examples.
 * (bug 4488) There is now a preference to watch pages where the user has rollbacked an edit by default.
 * (bug 15484) Users will now be redirected to the login page when they need to log in, rather than being shown a page asking them to log in and having to click another link to actually get to the login page.
 * A JsonContent and JsonContentHandler were added for extensions to extend.
 * (bug 35045) Redirects to sections will now update the URL in browser's address bar using the HTML5 History API. When Dog redirects to Animals, the user will now see "Animals#Dog" in their browser instead of "Dog#Dog".
 * API token handling has been rewritten. Any API module using tokens will need to be updated. See the entry below under "Action API internal changes".
 * Added HTMLAutoCompleteSelectField.
 * Added a new hook, "SkinPreloadExistence", to allow extensions to add titles to link existence cache before the page is rendered.
 * Config::set was moved to its own interface, MutableConfig. GlobalVarConfig::set is now deprecated, does not implement MutableConfig.
 * A MutableConfig named HashConfig was added, that stores an array of configuration settings.
 * (bug 69418) A MultiConfig implementation was added that supports fallback to multiple Config instances.

Corrections de bugs

 * (bug 50572) MediaWiki:Blockip should support gender
 * (bug 49116) Footer copyright notice is now always displayed in user language rather than content language (same as copyright notice for editing interface).
 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height restriction was present in the parameters. Images with both the "frame" option and a size specification set will now always ignore the provided size and display an unscaled image, as the documentation has always claimed it would.
 * (bug 39035) Improved Vector skin performance by removing collapsibleNav, which used to collapse some sidebar elements by default. This removes -list id suffixes like p-lang-list: instead of using things like #p-lang-list, you can do #p-lang .body ul.
 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer follow redirects to their target pages.
 * Parser now dies early if called recursively, instead of producing subtle bugs.
 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the remaining page content.
 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects in the file namespace and delete the file on the target page. It will still however delete the redirect page.
 * (bug 22683) and other uses of PPFrame::RECOVER_ORIG will correctly recover the original code of extension tags.
 * (bug 65757) MSSQL: Update script drops unnamed constraints to be prepared for future updates. Because it's doing so heuristically, it may fail or drop wrong constraints.
 * (bug 67870) wfShellExec cuts off stdout at multiples of 8192 bytes.
 * $wgRunJobsAsync now works with private wikis (e.g. read requires login).
 * (bugs 57238, 65206) Blank pages can now be directly created.
 * (bug 69789) Title::getContentModel now loads from the database when necessary instead of incorrectly returning the default content model.
 * (bug 69249) wfBaseConvert now works around PHP Bug #50175 when using GMP.
 * (bug 57909) URLs in the externallinks table will no longer have certain characters decoded in the query string.
 * LESS mixins like .background-image correctly flip image references for RTL stylesheets now.
 * SECURITY: User PleaseStand reported a way to inject code into API clients that used format=php to process pages that underwent flash policy mangling. This was fixed along with improving how the mangling was done for format=json, and allowing sites to disable the mangling using $wgMangleFlashPolicy.
 * SECURITY: User Jackmcbarn reported that the ability to update the content model for a page could allow an unprivileged attacker to edit another user's common.js under certain circumstances. The user right "editcontentmodel" was added, and is needed to change a revision's content model.
 * SECURITY: User PleaseStand reported that on wikis that allow raw HTML, it is not safe to preview wikitext coming from an untrusted source such as a cross-site request. Thus add an edit token to the form, and when raw HTML is allowed, ensure the token is provided before showing the preview. This check is not performed on wikis that both allow raw HTML and anonymous editing, since there are easier ways to exploit that scenario.
 * SECURITY: Do not show log action when the entry is revdeleted with DELETED_ACTION. NOTICE: this may be reverted in a future release pending a public RFC about the desired functionality. This issue was reported by user Bawolff.
 * Make allowing site-wide styles on restricted special pages a config option.
 * Added updated version history from 1.19.2 to 1.22.13
 * $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that might be a flash policy directive configurable.

Changements de l’API action

 * action=parse API now supports prop=modules, which provides the list of ResourceLoader modules that should be used to enhance the parsed content.
 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel" field which is true if protocol-relative urls can be used to access a particular interwiki map entry.
 * list=logevents now provides logpage, which is the page ID from the logging table, if ids are requested and the user has the permissions.
 * action=edit now requires that appendtext, prependtext, or section=new be used when using the 'redirect' parameter, to prevent clients accidentally overwriting the target page with the content of the redirect.
 * list=logevents will now return an error if both letitle and leprefix are specified.
 * list=logevents has a new parameter, lenamespace, to allow filtering by namespace.
 * action=expandtemplates has a new parameter, prop, and a new output format. The old format is still used if prop isn't provided, but this is deprecated.
 * meta=userinfo can now return the count of unread pages on the watchlist.
 * list=watchlist can now filter by unread status.
 * The deprecated action=parse&prop=languageshtml has been removed.
 * (bug 48071) action=setnotificationtimestamp no longer throws PHP or database errors when no pages are given.
 * (bug 60734) Actions that use ApiPageSet (e.g. purge, watch, setnotificationtimestamp) will now include continuation information when using a generator.
 * Removed 'props' and 'errors' from action=paraminfo, as they have extremely limited use and are generally inaccurate, unmaintained, and impossible to properly maintain.
 * Formats dbg, dump, txt, wddx, and yaml are now deprecated.
 * action=paraminfo now indicates when a parameter is specifying a submodule.
 * The iwurl parameter to prop=iwlinks is deprecated in favor of iwprop=url, for parallelism with prop=langlinks.
 * All tokens should be fetched from action=query&meta=tokens; all other methods of fetching tokens are deprecated. The value needed for meta=tokens's 'type' parameter for each module is documented in the action=help output and is returned from action=paraminfo.
 * New action ClearHasMsg that can be used to clear HasMsg flag.
 * The cmstartsortkey and cmendsortkey parameters to list=categorymembers are deprecated in favor of cmstarthexsortkey and cmendhexsortkey.
 * (bug 63326) Add blockedtimestamp field to output of blockinfo property for the list=allusers and list=users modules.
 * prop=imageinfo no longer requires iiurlwidth to be set when using iiurlparam.
 * Added prop=linkshere, prop=fileusage, and prop=transcludedin, which are roughly equivalent to list=backlinks, list=imageusage, and list=embeddedin but can work on a list of titles (including titles from a generator).
 * prop=redirects can now filter returned redirects by namespace.

Changements internes de l’API action

 * Methods for handling continuation are added to ApiResult, so actions other than query that use generators can easily support continuation.
 * $wgAPIModules (and the related $wgAPIFormatModules, $wgAPIMetaModules, $wgAPIPropModules, and $wgAPIListModules settings) now allow API modules to be specified using a "module spec" array instead of a plain class name. A "module spec" is an associative array containing at least the 'class' key for the module's class, and optionally a 'factory' key for the factory function to use for the module. This is intended for extensions that want control over the instantiation of their API modules, to allow for proper dependency injection.
 * A new param type 'submodule' is available. Parameters of this type will take the list of valid values from the module's ApiModuleManager for the group corresponding to the parameter name.
 * The 'APIGetPossibleErrors' and 'APIGetResultProperties' hooks are no longer used.
 * API token handling has been rewritten. Any API module using tokens will need to be updated:
 * ApiBase::needsToken now returns a token type instead of boolean true when a token is needed. Returning true will throw an exception. See documentation of that method for details.
 * Information for the 'token' parameter is automatically set by ApiBase getFinalParams and getFinalParamDescription.
 * ApiBase::getTokenSalt has been removed.
 * The hooks APIQueryInfoTokens, APIQueryRevisionsTokens, APIQueryRecentChangesTokens, APIQueryUsersTokens, and ApiTokensGetTokenTypes are deprecated, but are still called to support backwards-compatible token access.
 * ApiBase::validateLimit and ApiBase::validateTimestamp are now protected.
 * ApiQueryRedirects was removed; prop=redirects is now implemented by ApiQueryBacklinksProp along with the newly-added prop modules.
 * The following methods have been deprecated and may be removed in a future release:
 * ApiBase::getResultProperties
 * ApiBase::getFinalResultProperties
 * ApiBase::addTokenProperties
 * ApiBase::getRequireOnlyOneParameterErrorMessages
 * ApiBase::getRequireMaxOneParameterErrorMessages
 * ApiBase::getRequireAtLeastOneParameterErrorMessages
 * ApiBase::getTitleOrPageIdErrorMessage
 * ApiBase::getPossibleErrors
 * ApiBase::getFinalPossibleErrors
 * ApiBase::parseErrors
 * ApiQuery::setGeneratorContinue
 * ApiQueryBase::checkRowCount
 * ApiQueryBase::titleToKey
 * ApiQueryBase::keyToTitle
 * ApiQueryBase::keyPartToTitle
 * ApiQueryInfo::getTokenFunctions
 * ApiQueryInfo::resetTokenCache
 * ApiQueryInfo::getEditToken
 * ApiQueryInfo::getDeleteToken
 * ApiQueryInfo::getProtectToken
 * ApiQueryInfo::getMoveToken
 * ApiQueryInfo::getBlockToken
 * ApiQueryInfo::getUnblockToken
 * ApiQueryInfo::getEmailToken
 * ApiQueryInfo::getImportToken
 * ApiQueryInfo::getWatchToken
 * ApiQueryInfo::getOptionsToken
 * ApiQueryRecentChanges::getTokenFunctions
 * ApiQueryRecentChanges::getPatrolToken
 * ApiQueryRevisions::getTokenFunctions
 * ApiQueryRevisions::getRollbackToken
 * ApiQueryUsers::getTokenFunctions
 * ApiQueryUsers::getUserrightsToken
 * The following classes have been deprecated and may be removed in a future release:
 * ApiFormatDbg
 * ApiFormatDump
 * ApiFormatTxt
 * ApiFormatWddx
 * ApiFormatYaml
 * ApiTokens

Langues mises à jour
MediaWiki supporte plus de 350 langues. Beaucoup de localisations sont mises à jour régulièrement. Ci-dessous sont listés les langues nouvelles ainsi que celles qui sont enlevées, de même que les modifications de langue liées aux rapports Bugzilla.

Autres modifications
- skins/common/commonElements.css → 'mediawiki.skinning.elements' module - skins/common/commonContent.css  → 'mediawiki.skinning.content' module - skins/common/commonInterface.css → 'mediawiki.skinning.interface' module
 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 * The deprecated function mw.util.toggleToc was removed.
 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend were removed as they were unused.
 * (bug 65477) User::pingLimiter now has an additional profile point varying by action being used.
 * mediawiki.util.$content no longer supports old versions of the Vector, MonoBook, Modern and CologneBlue skins that don't yet implement the "mw-body" and/or "mw-body-primary" class name in their html.
 * Added pp_sortkey column to page_props table, so pages can be efficiently queried and sorted by property value (bug 58032). See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 * BREAKING CHANGE: All four built-in MediaWiki skins (Vector, Monobook, Modern and Cologne Blue) were moved out of MediaWiki core to their own respective repositories.

 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use the "headelement" template key are no longer supported. Setting $useHeadElement = false; is no longer supported and will not cause old keys like "headlinks", "skinnameclass", etc. to be defined.
 * BREAKING CHANGE: The files commonElements.css, commonContent.css and commonInterface.css (in skins/common/) have been removed. Skins may no longer rely on their presence and include them in their style modules. ResourceLoader modules introduced in MediaWiki 1.23 should be loaded instead:

Compatibilité
MediaWiki 1.24 nécessite PHP version 5.3.2 ou ultérieure. Il y a un support expérimental pour HHVM 3.3.0.

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

Les versions supportées sont :

SQLite version 3.3.7 ou ultérieure
 * MySQL version 5.0.2 ou ultérieure
 * PostgreSQL version 8.3 ou ultérieure
 * Note : Si vous utilisez la version 1.24.0, il se peut que vous ayez à mettre en place cette modification pour installer MediaWiki. Utilisez soit git ou copier ce fichier dans.
 * Oracle version 9.0.1 ou ultérieure
 * Microsoft SQL Server 2005 (version 9.00.1399)

Mise à jour
La version 1.24 a reçu plusieurs modifications de la base de données par rapport à la version 1.23 et ne fonctionnera pas sans mises à jour des schémas Veuillez noter que les modifications appliquées aux tables fournies comme la table de révision impliqueront un temps assez important de mise à jour (de quelques minutes sur un site de taille moyenne à plusieurs heures pour un site de taille conséquente).

Si vous effectuez une mise à jour depuis une version antérieure à la 1.11 et que vous utilisez un wiki en tant que bibliothèque commune, assurez-vous de mettre aussi à jour celle-ci. Autrement, vous pourriez avoir des erreurs liées aux changements de schémas de la base de données.

Si vous effectuez une mise à jour depuis une version antérieure à la 1.7, il faudra certainement lancer refreshLinks.php pour s'assurer que les nouveaux champs de la base de données soient bien remplis avec les données correspondantes.

Si vous effectuez une mise à jour depuis une version 1.4.x ou antérieure, vous devriez tout d'abord effectuer une première mise à jour vers la version 1.5. Le script de mise à jour maintenance/upgrade1_5.php a été retiré depuis la version 1.21

N'oubliez pas de toujours faire une sauvegarde de votre base de données avant de faire une mise à jour !

Lisez le fichier UPGRADE (en anglais) pour de plus amples instructions concernant la mise à jour.

Pour les notes concernant les versions 1.23.x et antérieurs, voir HISTORY (en anglais).
