MediaWiki 1.21

[edit]

Configuration changes

[edit]

New features

[edit]
  • (bug 41769) Add parser method to call parser functions.
  • (bug 38110) Schema changes (adding or dropping tables, indices and fields) can be now be done separately from from other changes that update.php makes. This is useful in environments that use database permissions to restrict schema changes but allow the DB user that MediaWiki normally runs as to perform other changes that update.php makes. Schema changes can be run separately. See the file UPGRADE for more information.
  • (bug 34876) jquery.makeCollapsible has been improved in performance.
  • Added ContentHandler facility to allow extensions to support other content than wikitext. See docs/contenthandler.txt for details.
  • New feature was developed for showing high-DPI thumbnails for high-DPI mobile and desktop displays (configurable with $wgResponsiveImages ).
  • Added new backend to represent and store information about sites and site specific configuration.
  • jQuery upgraded from 1.8.2 to 1.8.3.
  • jQuery UI upgraded from 1.8.23 to 1.8.24.
  • Added separate fa_sha1 field to filearchive table. This allows sha1 searches with the api in miser mode for deleted files.
  • Add initial and programmatic sorting for tablesorter.
  • Add the event "sortEnd.tablesorter", triggered after sorting has completed.
  • The Job system was refactored to allow for different backing stores for queues as well as cross-wiki access to queues, among other things. The schema for the DB queue was changed to support better concurrency and reduce deadlock errors.
  • Added ApiQueryORM class to facilitate creation of query API modules based on tables that have a corresponding ORMTable class.
  • (bug 40876) Icon for PSD (Adobe Photoshop) file types.
  • (bug 40641) Implemented Special:Version/Credits with a list of contributors.
  • (bug 7851) Implemented one-click AJAX patrolling.
  • The <data>, <time>, <meta>, and <link> elements are allowed within WikiText for use with Microdata.
  • The HTML5 <mark> tag has been whitelisted.
  • Added ParserCloned hook for when the Parser object is cloned.
  • Added AlternateEditPreview hook to allow extensions to replace the page preview from the edit page.
  • Added EditPage::showStandardInputs:options hook to allow extensions to add new fields to the "editOptions" area of the edit form.
  • Upload stash DB schema altered to improve upload performance.
  • The following global functions are now reporting deprecated warnings in debug mode: wfMsg, wfMsgNoTrans, wfMsgForContent, wfMsgForContentNoTrans, wfMsgReal, wfMsgGetKey, wfMsgHtml, wfMsgWikiHtml, wfMsgExt, wfEmptyMsg. Use the Message class, or the global method wfMessage.
  • Added $wgEnableCanonicalServerLink , off by default. If enabled, a <link rel=canonical> tag is added to every page indicating the correct server to use.
  • Debug message emitted by wfDebugLog() will now be prefixed with the group name when its logged to the default log file. That is the case whenever the group has no key in wgDebugLogGroups, that will help triage the default log.
  • (bug 24620) Add types to LogFormatter.
  • jQuery JSON upgraded from 2.3 to 2.4.0.
  • Added GetDoubleUnderscoreIDs hook, for modifying the list of magic words.
  • DatabaseUpdater class has two new methods to ease extensions schema changes: dropExtensionIndex and renameExtensionIndex.
  • New preference type - 'api'. Preferences of this type are not shown on Special:Preferences, but are still available via the action=options API.
  • (bug 39397) Hide rollback link if a user is the only contributor of the page.
  • $wgPageInfoTransclusionLimit limits the list size of transcluded articles on the info action. Default is 50.
  • Added action=createaccount to allow user account creation.
  • (bug 40124) action=options API also allows for setting of arbitrary preferences, provided that their names are prefixed with 'userjs-'. This officially reenables the feature that was undocumented and defective in MW 1.20 (saving preferences using Special:Preferences cleared any additional fields) and which has been disabled in 1.20.1 as a part of a security fix (bug 42202).
  • Added option to specify "others" as author in extension credits using "..." as author name.
  • Added the ability to limit the wall clock time used by shell processes, as well as the CPU time. Configurable with $wgMaxShellWallClockTime .
  • Allow memory of shell subprocesses to be limited using Linux cgroups instead of ulimit -v, which tends to cause deadlocks in recent versions of ImageMagick. Configurable with $wgShellCgroup .
  • Added $wgWhitelistReadRegexp for regex whitelisting.
  • (bug 5346) Categories that are redirects will be displayed italic in the category links section at the bottom of a page.
  • (bug 43915) New maintenance script deleteEqualMessages.php.
  • You can now create checkbox option matrices through the HTMLCheckMatrix subclass in HTMLForm.
  • WikiText now permits the use of WAI-ARIA's role="presentation" inside of html elements and tables. This allows presentational markup, especially tables. To be marked up as such.
  • maintenance/sql.php learned the --cluster option. Let you run the script on some external cluster instead of the primary cluster for a given wiki.
  • (bug 20281) test the parsing of inline URLs.
  • Added Special:PagesWithProp, which lists pages using a particular page property.
  • Implemented language-specific collations for category sorting for 67 languages based in latin, greek and cyrillic alphabets. This allows one to *finally* get articles to be correctly sorted on category pages. They are named 'uca-<langcode>', where <langcode> is one of: af, ast, az, be, bg, br, bs, ca, co, cs, cy, da, de, dsb, el, en, eo, es, et, eu, fi, fo, fr, fur, fy, ga, gd, gl, hr, hsb, hu, is, it, kk, kl, ku, ky, la, lb, lt, lv, mk, mo, mt, nl, no, oc, pl, pt, rm, ro, ru, rup, sco, sk, sl, smn, sq, sr, sv, tk, tl, tr, tt, uk, uz, vi.
  • Added 'CategoryAfterPageAdded' and 'CategoryAfterPageRemoved' hooks.
  • Added 'HistoryRevisionTools' and 'DiffRevisionTools' hooks.
  • Added 'SpecialSearchResultsPrepend' and 'SpecialSearchResultsAppend' hooks.
  • (bug 33186) Add image rotation api "imagerotate"
  • (bug 34040) Add "User rights management" link on user page toolbox.
  • (bug 45526) Add QUnit assertion helper "QUnit.assert.htmlEqual" for asserting structual equality of HTML (ignoring insignificant differences like quotmarks, order and whitespace in the attribute list).

API changes

[edit]
BREAKING CHANGE
Chunked uploads are now disabled by default. You can re-enable them by setting $wgAllowChunkedUploads =true
BREAKING CHANGE
list=logevents output format changed for details of some log types. Specifically, details that were formerly reported under a key like "4::foo" will now be reported under a key of simply "foo".
BREAKING CHANGE
'??_badcontinue' error code was changed to '??badcontinue' for all query modules.
  • prop=revisions can now report the contentmodel and contentformat. See docs/contenthandler.txt.

  • list=alllinks & alltransclusions now allow 'unique' in generators, to yield a list of all link/template target pages instead of source pages.
  • ApiQueryBase adds 'badcontinue' error code if module has 'continue' parameter.

  • action=help supports generalized submodules (modules=query+value), querymodules obsolete
  • ApiQueryImageInfo continuation is more reliable. The only major change is that the imagerepository property will no longer be set on page objects not processed in the current query (i.e. non-images or those skipped due to iicontinue).
  • Add supports for all pageset capabilities - generators, redirects, converttitles to action=purge and action=setnotificationtimestamp.
  • (bug 43251) prop=pageprops&ppprop= now accepts multiple props to query.
  • ApiQueryImageInfo will now limit the number of calls to File::transform made in any one query. If there are too many, iicontinue will be returned.

  • (bug 44244) prop=info may now return the number of people watching each page.

API internal changes

[edit]
BREAKING CHANGE
ApiPageSet constructor now has two params instead of three, with only the first one keeping its meaning. ApiPageSet is now derived from ApiBase.
BREAKING CHANGE
ApiQuery::newGenerator() and executeGeneratorModule() were deleted.
  • For debugging only, a new global $wgDebugAPI removes many API restrictions when true. Never use on the production servers, as this flag introduces security holes. Whenever enabled, a warning will also be added to all output.
  • ApiModuleManager now handles all submodules (actions,props,lists) and instantiation
  • Query stores prop/list/meta as submodules
  • ApiPageSet can now be used in any action to process titles/pageids/revids or any generator.
  • ApiQueryGeneratorBase::setGeneratorMode() now requires a pageset param.
  • $wgAPIGeneratorModules is now obsolete and will be ignored.
  • Added flags ApiResult::OVERRIDE and ADD_ON_TOP to setElement() and addValue()
  • Internal API calls will now include <warnings> in case of unused parameters

Languages updated

[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 Bugzilla reports.

  • South Azerbaijani (azb) added.
  • (bug 30040) Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').
  • (bug 45436) Autonym for pi (Pali) is now 'पालि' (was 'पाळि').
  • (bug 34977) Now formatted numbers in Spanish use space as separator for thousands, as mandated by the Real Academia Española.
  • (bug 35031) Kurdish formatted numbers now use period and comma as separators for thousands and decimals respectively.

Other changes

[edit]
  • Experimental IBM DB2 support was removed due to lack of interest and maintainership.
BREAKING CHANGE
(bug 44385) Removed the jquery.collapsibleTabs module and moved it to the Vector extension. It was entirely Vector-extension-specific, deeply interconnected with the extension, and this functionality really belongs to the extension instead of the skin anyway. In the unlikely case you were using it, you have to either copy it to your extension, or install the Vector extension (and possibly disable its features using config settings if you don't want them).
BREAKING CHANGE
Filenames of maintenance scripts were standardized into lowerCamelCase format, and made more explicit:
  • clear_stats.php → clearCacheStats.php
  • clear_interwiki_cache.php → clearInterwikiCache.php
  • initStats.php → initSiteStats.php
  • proxy_check.php → proxyCheck.php
  • stats.php → showCacheStats.php
  • showStats.php → showSiteStats.php.
Class names were renamed accordingly:
  • clear_stats → ClearCacheStats
  • InitStats → InitSiteStats
  • CacheStats → ShowCacheStats
  • ShowStats → ShowSiteStats.
BREAKING CHANGE
(bug 38244) Removed the mediawiki.api.titleblacklist module and moved it to the TitleBlacklist extension.

Compatibility

[edit]

MediaWiki 1.21 requires PHP 5.3.2 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.

The supported versions are:

  • MySQL 5.0.2 or later
  • PostgreSQL 8.3 or later
  • SQLite 3.3.7 or later
  • Oracle 9.0.1 or later

Upgrading

[edit]

1.21 has several database changes since 1.20, 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 1.19.x and older releases, see HISTORY.

Online documentation

[edit]

Documentation for both end-users and site administrators is available on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain):

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 the IRC channel #mediawiki connect.
