Upstream changes:
== Security fixes ==
* Wikipedia user RobinHood70 reported two issues in the chunked upload API.
The API failed to correctly stop adding new chunks to the upload when the
reported size was exceeded (T91203), allowing a malicious users to upload add an
infinite number of chunks for a single file upload. Additionally, a
malicious user could upload chunks of 1 byte for very large files, potentially
creating a very large number of files on the server's filesystem (T91205).
<https://phabricator.wikimedia.org/T91203>
<https://phabricator.wikimedia.org/T91205>
* Internal review discovered that it is not possible to throttle file
uploads.
<https://phabricator.wikimedia.org/T91850>
* Internal review discovered a missing authorization check when removing
suppression from a revision. This allowed users with the 'viewsuppressed'
user right but not the appropriate 'suppressrevision' user right to unsuppress
revisions.
<https://phabricator.wikimedia.org/T95589>
* Richard Stanway from teamliquid.net reported that thumbnails of PNG files
generated with ImageMagick contained the local file path in the image
metadata.
<https://phabricator.wikimedia.org/T108616>
== Bug Fixes in 1.25.3 ==
* Fix having multiple callbacks for a single hook.
<https://phabricator.wikimedia.org/T98975>
* maintenance/refreshLinks.php did not always remove all links pointing to
nonexistent pages.
<https://phabricator.wikimedia.org/T107632>
* $wgEmergencyContact and $wgPasswordSender now use their default value if
set to an empty string.
<https://phabricator.wikimedia.org/T104142>
* Provide fallbacks for use of mb_convert_encoding() in HtmlFormatter. It
was causing an error when accessing the api help page if the mbstring PHP
extension was not installed.
<https://phabricator.wikimedia.org/T62174>
* Confirmation emails would sometimes contain invalid codes.
<https://phabricator.wikimedia.org/T105896>
* Fixed edit stash inclusion queries.
<https://phabricator.wikimedia.org/T105597>
Upstream changes:
== Security fixes ==
* Internal review discovered that Special:DeletedContributions did not
properly
protect the IP of autoblocked users. This fix makes the functionality of
Special:DeletedContributions consistent with Special:Contributions and
Special:BlockList.
<https://phabricator.wikimedia.org/T106893>
* Internal review discovered that watchlist anti-csrf tokens were not being
compared in constant time, which could allow various timing attacks. This
could
allow an attacker to modify a user's watchlist via csrf.
<https://phabricator.wikimedia.org/T94116>
* John Menerick reported that MediaWiki's thumb.php failed to sanitize
various
error messages, resulting in xss.
<https://phabricator.wikimedia.org/T97391>
Additionally, the following extensions have been updated to fix security
issues:
* Extension:SemanticForms - MediaWiki user Grunny discovered multiple
reflected
xss vectors in SemanticForms. Further internal review discovered and fixed
other reflected and stored xss vectors.
<https://phabricator.wikimedia.org/T103391>
<https://phabricator.wikimedia.org/T103765>
<https://phabricator.wikimedia.org/T103761>
* Extension:SyntaxHighlight_GeSHi - xss and potential DoS vectors. Internal
review discovered that the contib directory for GeSHi was re-included in
MediaWiki 1.25. Some scripts could be potentially be used for DoS, and
DAU Huy Ngoc discovered an xss vector. All contrib scripts have been
removed.
<https://phabricator.wikimedia.org/T108198>
* Extension:TimedMediaHandler - User:McZusatz reported that resetting
transcodes deleted the transcode without creating a new one, which could be
used for vandalism or potentially DoS.
<https://phabricator.wikimedia.org/T100211>
* Extension:Quiz - Internal review discovered that Quiz did not properly
escape
regex metacharacters in a user controlled regular expression, enabling a DoS
vector.
<https://phabricator.wikimedia.org/T97083>
* Extension:Widgets - MediaWiki developer Majr reported a potential HTML
injection (xss) vector.
<https://phabricator.wikimedia.org/T88964>
== Bug Fixes in 1.25.2 ==
* (T102562) Fix InstantCommons parameters to handle the new HTTPS-only
policy of Wikimedia Commons.
* (T100767) Setting a configuration setting for skin or extension to
false in LocalSettings.php was not working.
* (T100635) API action=opensearch json output no longer breaks when
$wgDebugToolbar is enabled.
* (T102522) Using an extension.json or skin.json file which has
a "manifest_version" property for 1.26 compatability will no longer
trigger warnings.
* (T86156) Running updateSearchIndex.php will not throw an error as
page_restrictions has been added to the locked table list.
* Special:Version would throw notices if using SVN due to an incorrectly
named variable. Add an additional check that an index is defined.
Upstream changes:
== MediaWiki 1.25.1 ==
This is a bug fix release of the MediaWiki 1.25 branch.
== Changes since 1.25.1 ==
* (T100351) Fix syntax errors in extension.json of ConfirmEdit extension
== MediaWiki 1.25 ==
=== Configuration changes in 1.25 ===
* $wgPageShowWatchingUsers was removed.
* $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
* $wgAntiLockFlags was removed.
* $wgJavaScriptTestConfig was removed.
* Edit tokens returned from User::getEditToken may change on every call. Token
validity must be checked by passing the user-supplied token to
User::matchEditToken rather than by testing for equality with a
newly-generated token.
* (T74951) The UserGetLanguageObject hook may be passed any IContextSource
for its $context parameter. Formerly it was documented as receiving a
RequestContext specifically.
* Profiling was restructured and $wgProfiler now requires an 'output' parameter.
See StartProfiler.sample for details.
* $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
might be a flash policy directive configurable.
* ApiOpenSearch now supports XML output. The OpenSearchXml extension should no
longer be used. If extracts and page images are desired, the TextExtracts and
PageImages extensions are required.
* $wgOpenSearchTemplate is deprecated in favor of $wgOpenSearchTemplates.
* Edits are now prepared via AJAX as users type edit summaries. This behavior
can be disabled via $wgAjaxEditStash.
* (T46740) The temporary option $wgIncludejQueryMigrate was removed, along
with the jQuery Migrate library, as indicated when this option was provided in
MediaWiki 1.24.
* ProfilerStandard and ProfilerSimpleTrace were removed. Make sure that any
StartProfiler.php config is updated to reflect this. Xhprof is available
for zend/hhvm. Also, for hhvm, one can consider using its xenon profiler.
* Default value of $wgSVGConverters['rsvg'] now uses the 'rsvg-convert' binary
rather than 'rsvg'.
* Default value of $wgSVGConverters['ImageMagick'] now uses transparent
background with white fallback color, rather than just white background.
* MediaWikiBagOStuff class removed, make sure any object cache config
uses SqlBagOStuff instead.
* The 'daemonized' flag must be set to true in $wgJobTypeConf for any redis
job queues. This means that mediawiki/services/jobrunner service has to
be installed and running for any such queues to work.
* $wgAutopromoteOnce no longer supports the 'view' event. For keeping some
compatibility, any 'view' event triggers will still trigger on 'edit'.
* $wgExtensionDirectory was added for when your extensions directory is somewhere
other than $IP/extensions (as $wgStyleDirectory does with the skins directory).
=== New features in 1.25 ===
* (T64861) Updated plural rules to CLDR 26. Includes incompatible changes
for plural forms in Russian, Prussian, Tagalog, Manx and several languages
that fall back to Russian.
* (T60139) ResourceLoaderFileModule now supports language fallback
for 'languageScripts'.
* Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
parser output for a content object before links update.
* (T37785) Enhanced recent changes and extended watchlist are now default.
Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
* (T69341) SVG images will no longer be base64-encoded when being embedded
in CSS. This results in slight size increase before gzip compression (due to
percent-encoding), but up to 20% decrease after it.
* Update jStorage to v0.4.12.
* MediaWiki now natively supports page status indicators: icons (or short text
snippets) usually displayed in the top-right corner of the page. They have
been in use on Wikipedia for a long time, implemented using templates and CSS
absolute positioning.
- Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
- Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
- Adjusting custom skins to support indicators:
https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
* Edit tokens may now be time-limited: passing a maximum age to
User::matchEditToken will reject any older tokens.
* The debug logging internals have been overhauled, and are now using the
PSR-3 interfaces.
* Update CSSJanus to v1.1.1.
* Update lessphp to v0.5.0.
* Added a hook, "ApiOpenSearchSuggest", to allow extensions to provide extracts
and images for ApiOpenSearch output. The semantics are identical to the
"OpenSearchXml" hook provided by the OpenSearchXml extension.
* PrefixSearchBackend hook now has an $offset parameter. Combined with $limit,
this allows for pagination of prefix results. Extensions using this hook
should implement supporting behavior. Not doing so can result in undefined
behavior from API clients trying to continue through prefix results.
* Update jQuery from v1.11.1 to v1.11.3.
* External libraries installed via composer will now be displayed
on Special:Version in their own section. Extensions or skins that are
installed via composer will not be shown in this section as it is assumed
they will add the proper credits to the skins or extensions section. They
can also be accessed through the API via the new siprop=libraries to
ApiQuerySiteInfo.
* Update QUnit from v1.14.0 to v1.16.0.
* Update Moment.js from v2.8.3 to v2.8.4.
* Special:Tags now allows for manipulating the list of user-modifiable change
tags.
* Added 'managetags' user right and 'ChangeTagCanCreate', 'ChangeTagCanDelete',
and 'ChangeTagCanCreate' hooks to allow for managing user-modifiable change
tags.
* Added 'ChangeTagsListActive' hook, to separate the concepts of "defined" and
"active" formerly conflated by the 'ListDefinedTags' hook.
* Added TemplateParser class that provides a server-side interface to cachable
dynamically-compiled Mustache templates (currently uses lightncandy library).
* Clickable anchors for each section heading in the content are now generated
and appear in the gutter on hovering over the heading.
* Added 'CategoryViewer::doCategoryQuery' and 'CategoryViewer::generateLink' hooks
to allow extensions to override how links to pages are rendered within NS_CATEGORY
* (T19665) Special:WantedPages only lists page which having at least one red link
pointing to it.
* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
used for conditional registration of API modules.
* New hook 'EnhancedChangesList::getLogText' to alter, remove or add to the
links of a group of changes in EnhancedChangesList.
* A full interface for StatsD metric reporting has been added to the context
interface, reachable via IContextSource::getStats().
* Move the jQuery Client library from being mastered in MediaWiki as v0.1.0 to a
proper, published library, which is now tagged as v1.0.0.
* A new message (defaulting to blank), 'editnotice-notext', can be shown to users
when they are editing if no edit notices apply to the page being edited.
* (T94536) You can now make the sitenotice appear to logged-in users only by
editing MediaWiki:Anonnotice and replacing its content with "". Setting it to
"-" (default) will continue disable it and fallback to MediaWiki:Sitenotice.
* Modifying the tagging of a revision or log entry is now available via
Special:EditTags, generally accessed via the revision-deletion-like interface
on history pages and Special:Log is likely to be more useful.
* Added 'applychangetags' and 'changetags' user rights.
* (T35235) LogFormatter subclasses are now responsible for formatting the
parameters for API log event output. Extensions should implement the new
getParametersForApi() method in their log formatters.
==== External libraries ====
* MediaWiki now requires certain external libraries to be installed. In the past
these were bundled inside the Git repository of MediaWiki core, but now they
need to be installed separately. For users using the tarball, this will be taken
care of and no action will be required. Users using Git will either need to use
composer to fetch dependencies or use the mediawiki/vendor repository which includes
all dependencies for MediaWiki core and ones used in Wikimedia deployment. Detailed
instructions can be found at:
https://www.mediawiki.org/wiki/Download_from_Git#Fetch_external_libraries
* The following libraries are now required:
** psr/log
This library provides the interfaces set by the PSR-3 standard (http://www.php-fig.org/psr/psr-3/)
which are used by MediaWiki internally via the
MediaWiki\Logger\LoggerFactory class.
See the structured logging RfC (https://www.mediawiki.org/wiki/Requests_for_comment/Structured_logging)
for more background information.
** cssjanus/cssjanus
This library was formerly bundled with MediaWiki core and has been removed.
It automatically flips CSS for RTL support.
** leafo/lessphp
This library was formerly bundled with MediaWiki core and has been removed.
It compiles LESS files into CSS.
** wikimedia/cdb
This library was formerly a part of MediaWiki core, and has been moved into a separate library.
It provides CDB functions which are used in the Interwiki and Localization caches.
More information about the library can be found at https://www.mediawiki.org/wiki/CDB.
** liuggio/statsd-php-client
This library provides a StatsD client API for logging application metrics to a remote server.
=== Bug fixes in 1.25 ===
* (T73003) No additional code will be generated to try to load CSS-embedded
SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
* (T69021) On Special:BookSources, corrected validation of ISBNs (both
10- and 13-digit forms) containing "X".
* Page moving was refactored into a MovePage class. As part of that:
** The AbortMove hook was removed.
** MovePageIsValidMove is for extensions to specify whether a page
cannot be moved for technical reasons, and should not be overridden.
** MovePageCheckPermissions is for checking whether the given user is
allowed to make the move.
** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
** Title::moveTo() was deprecated. Use the MovePage class instead.
** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
and MovePage::checkPermissions().
* (T18530) Multiple autocomments are now formatted in an edit summary.
* (T70361) Autocomments containing "/*" are parsed correctly.
* The Special:WhatLinksHere page linked from 'Number of redirects to this page'
on action=info about a file page does not list file links anymore.
* (T78637) Search bar is not autofocused unless it is empty so that proper scrolling using arrow keys is possible.
* (T50853) Database::makeList() modified to handle 'NULL' separately when building IN clause
* (T85192) Captcha position modified in Usercreate template. As a result:
** extrafields parameter added to Usercreate.php to insert additional data
** 'extend' method added to QuickTemplate to append additional values to any field of data array
* (T86974) Several Title methods now load from the database when necessary
(instead of returning incorrect results) even when the page ID is known.
* (T74070) Duplicate search for archived files on file upload now omits the extension.
This requires the fa_sha1 field being populated.
* Removed rel="archives" from the "View history" link, as it did not pass
HTML validation.
* $wgUseTidy is now set when parserTests are run with the tidy option to match
output on wiki.
* (T37472) update.php will purge ResourceLoader cache unless --nopurge is passed to it.
* (T72109) mediawiki.language should respect $wgTranslateNumerals in convertNumber().
=== Action API changes in 1.25 ===
* (T67403) XML tag highlighting is now only performed for formats
"xmlfm" and "wddxfm".
* action=paraminfo supports generalized submodules (modules=query+value),
querymodules and formatmodules are deprecated
* action=paraminfo no longer outputs descriptions and other help text by
default. If needed, it may be requested using the new 'helpformat' parameter.
* action=help has been completely rewritten, and outputs help in HTML
rather than plain text.
* Hitting api.php without specifying an action now displays only the help for
the main module, with links to submodule help.
* API help is no longer displayed on errors.
* 'uselang' is now a recognized API parameter; "uselang=user" may be used to
explicitly select the language from the current user's preferences, and
"uselang=content" may be used to select the wiki's content language.
* Default output format for the API is now jsonfm.
* Simplified continuation will return a "batchcomplete" property in the result
when a batch of pages is complete.
* Pretty-printed HTML output now has nicer formatting and (if available)
better syntax highlighting.
* Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
list=alldeletedrevisions.
* prop=revisions will gracefully continue when given too many revids or titles,
rather than just ignoring the extras.
* prop=revisions will no longer die if rvcontentformat doesn't match a
revision's content model; it will instead warn and omit the content.
* If the user has the 'deletedhistory' right, action=query's revids parameter
will now recognize deleted revids.
* prop=revisions may be used as a generator, generating revids.
* (T68776) format=json results will no longer be corrupted when
$wgMangleFlashPolicy is in effect. format=php results will cleanly return an
error instead of returning invalid serialized data.
* Generators may now return data for the generated pages when used with
action=query.
* Query page data for generator=search and generator=prefixsearch will now
include an "index" field, which may be used by the client for sorting the
search results.
* ApiOpenSearch now supports XML output.
* ApiOpenSearch will now output descriptions and URLs as array indexes 2 and 3
in JSON format.
* (T76051) list=tags will now continue correctly.
* (T76052) list=tags can now indicate whether a tag is defined.
* (T75522) list=prefixsearch now supports continuation
* (T78737) action=expandtemplates can now return page properties.
* (T78690) list=allimages now accepts multiple pipe-separated values
for the 'aimime' parameter.
* prop=info with inprop=protections will now return applicable protection types
with the 'restrictiontypes' key.
* (T85417) When resolving redirects, ApiPageSet will now add the targets of
interwiki redirects to the list of interwiki titles.
* (T85417) When outputting the list of redirect titles, a 'tointerwiki'
property (like the existing 'tofragment' property) will be set.
* Added action=managetags to allow for managing the list of
user-modifiable change tags. Actually modifying the tagging of a revision or
log entry is not implemented yet.
* list=tags has additional properties to indicate 'active' status and tag
sources.
* siprop=libraries was added to ApiQuerySiteInfo to list installed external libraries.
* (T88010) Added action=checktoken, to test a CSRF token's validity.
* (T88010) Added intestactions to prop=info, to allow querying of
Title::userCan() via the API.
* Default type param for query list=watchlist and list=recentchanges has
been changed from all types (e.g. including 'external') to 'edit|new|log'.
* Added formatversion to format=json. Still "experimental" as further changes
to the output formatting might still be made.
* (T73020) Log event details are now always under a 'params' subkey for
list=logevents, and a 'logparams' subkey for list=watchlist and
list=recentchanges.
* Log event details are changing formatting:
* block events now report flags as an array rather than as a comma-separated
list.
* patrol events now report the 'auto' flag as a boolean (absent/empty string
for BC formats) rather than as an integer.
* rights events now report the old and new group lists as arrays rather than
as comma-separated lists.
* merge events use new-style formatting.
* delete/event and delete/revision events use new-style formatting.
* The root node and various other nodes will now always be an object in formats
such as json that distinguish between arrays and objects.
* Except for action=opensearch where the spec requires an array.
=== Action API internal changes in 1.25 ===
* ApiHelp has been rewritten to support i18n and paginated HTML output.
Most existing modules should continue working without changes, but should do
the following:
* Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
* Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
to replace getParamDescription(). If necessary, the settings array returned
by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
message.
* Implement getExamplesMessages() to replace getExamples().
* Modules with submodules (like action=query) must have their submodules
override ApiBase::getParent() to return the correct parent object.
* The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
and will have no effect for modules using i18n messages. Use
'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
* Api formatters will no longer be asked to display the help screen on errors.
* ApiMain::getCredits() was removed. The credits are available in the
'api-credits' i18n message.
* ApiFormatBase has been changed to support i18n and syntax highlighting via
extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
has been removed.
* ApiFormatBase now always buffers. Output is done when
ApiFormatBase::closePrinter is called.
* Much of the logic in ApiQueryRevisions has been split into ApiQueryRevisionsBase.
* The 'revids' parameter supplied by ApiPageSet will now count deleted
revisions as "good" if the user has the 'deletedhistory' right. New methods
ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
provided to access just the live or just the deleted revids.
* Added ApiPageSet::setGeneratorData() and ApiPageSet::populateGeneratorData()
to allow generators to include data in the action=query result.
* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
used for conditional registration of API modules.
* Added ApiBase::lacksSameOriginSecurity() to allow modules to easily check if
the current request was sent with the 'callback' parameter (or any future
method that breaks the same-origin policy).
* Profiling methods in ApiBase are deprecated and no longer need to be called.
* ApiResult was greatly overhauled. See inline documentation for details.
* ApiResult will automatically convert objects to strings or arrays (depending
on whether a __toString() method exists on the object), and will refuse to
add unsupported value types.
* An informal interface, ApiSerializable, exists to override the default
object conversion.
* ApiResult/ApiFormatBase "raw mode" is deprecated.
* ApiFormatXml now assumes defaults and so on instead of throwing errors when
metadata isn't set.
* (T35235) LogFormatter subclasses are now responsible for formatting log event
parameters for the API.
* Many modules have changed result data formats. While this shouldn't affect
clients not using the experimental formatversion=2, code using
ApiResult::getResultData() without the transformations for backwards
compatibility may need updating, as will code that wasn't following the old
conventions for API boolean output.
* The following methods have been deprecated and may be removed in a future
release:
* ApiBase::getDescription
* ApiBase::getParamDescription
* ApiBase::getExamples
* ApiBase::makeHelpMsg
* ApiBase::makeHelpArrayToString
* ApiBase::makeHelpMsgParameters
* ApiBase::getModuleProfileName
* ApiBase::profileIn
* ApiBase::profileOut
* ApiBase::safeProfileOut
* ApiBase::getProfileTime
* ApiBase::profileDBIn
* ApiBase::profileDBOut
* ApiBase::getProfileDBTime
* ApiBase::getResultData
* ApiFormatBase::setUnescapeAmps
* ApiFormatBase::getWantsHelp
* ApiFormatBase::setHelp
* ApiFormatBase::formatHTML
* ApiFormatBase::setBufferResult
* ApiFormatBase::getDescription
* ApiFormatBase::getNeedsRawData
* ApiMain::setHelp
* ApiMain::reallyMakeHelpMsg
* ApiMain::makeHelpMsgHeader
* ApiResult::setRawMode
* ApiResult::getIsRawMode
* ApiResult::getData
* ApiResult::setElement
* ApiResult::setContent
* ApiResult::setIndexedTagName_recursive
* ApiResult::setIndexedTagName_internal
* ApiResult::setParsedLimit
* ApiResult::beginContinuation
* ApiResult::setContinueParam
* ApiResult::setGeneratorContinueParam
* ApiResult::endContinuation
* ApiResult::size
* ApiResult::convertStatusToArray
* ApiQueryImageInfo::getPropertyDescriptions
* ApiQueryLogEvents::addLogParams
* The following classes have been deprecated and may be removed in a future
release:
* ApiQueryDeletedrevs
=== Languages updated in 1.25 ===
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.
* Languages added:
** awa (अवधी / Awadhi), thanks to translator 1AnuraagPandey;
** bgn (بلوچی رخشانی / Western Balochi), thanks to translators
Baloch Afghanistan, Ibrahim khashrowdi and Rachitrali;
** ses (Koyraboro Senni), thanks to translator Songhay.
* (T66440) Kazakh (kk) wikis should no longer forcefully reset the user's
interface language to kk where unexpected.
* The Chinese conversion table was substantially updated to fix a lot of
bugs and ensure better reading experience for different variants.
=== Other changes in 1.25 ===
* (T45591) Links to MediaWiki.org translatable help were added to indicators,
mostly in special pages. Local custom target titles can be placed in the
relevant '(namespace-X|action name|special page name)-helppage' system
message. Extensions can use the addHelpLink() function to do the same.
* The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
migration guide for creators and users of custom skins that relied on it.
* Javascript variables 'wgFileCanRotate' and 'wgFileExtensions' now only
available on Special:Upload.
* (T58257) Set site logo from mediawiki.skinning.interface module instead of
inline styles in the HTML.
* Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
* Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
* Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
* Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
* Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
* Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
since 1.20)
* Removed 'async' parameter from the mw.Api#getCategories() method. (deprecated
since 1.20)
* Removed 'jquery.json' module. (deprecated since 1.24)
Use the 'json' module and global JSON object instead.
* Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
Also, the former will now throw an MWException if called with one or more
arguments.
* Removed hitcounters and associated code.
* The "temp" zone of the upload respository is now considered private. If it
already exists (such as under the images/ directory), please make sure that
the directory is not web readable (e.g. via a .htaccess file).
* BREAKING CHANGE: In the XML dump format used by Special:Export and
dumpBackup.php, the <model> and <format> tags now apprear before the <text>
tag, instead of after the <text> and <sha1> tags.
The new schema version is 0.10, the new schema URI is:
https://www.mediawiki.org/xml/export-0.10.xsd
* MWFunction::call() and MWFunction::callArray() were removed, having being
deprecated in 1.22.
* Deprecated the getInternalLinkAttributes, getInternalLinkAttributesObj,
and getInternalLinkAttributes methods in Linker, and removed
getExternalLinkAttributes method, which was deprecated in MediaWiki 1.18.
* Removed Sites class, which was deprecated in 1.21 and replaced by SiteSQLStore.
* Added wgRelevantArticleId to the client-side config, for use on special pages.
* Deprecated the TitleIsCssOrJsPage hook. Superseded by the
ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
* Deprecated the TitleIsWikitextPage hook. Superseded by the
ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
* Changed parsing of variables in schema (.sql) files:
** The substituted values are no longer parsed. (Formerly, several passes
were made for each variable, so depending on the order in which variables
were defined, variables might have been found inside encoded values. This
is no longer the case.)
** Variables are no longer string encoded when the /*$var*/ syntax is used.
If string encoding is necessary, use the '{$var}' syntax instead.
** Variable names must only consist of one or more of the characters
"A-Za-z0-9_".
** In source text of the form '{$A}'{$B}' or `{$A}`{$B}`, where variable A
does not exist yet variable B does, the latter may not be replaced.
However, this difference is unlikely to arise in practice.
* (T67278) RFC, PMID, and ISBN "magic links" must be surrounded by non-word
characters on both sides.
* The FormatAutocomments hook will now receive $pre and $post as booleans,
rather than as strings that must be prepended or appended to $comment.
* (T30950, T31025) RFC, PMID, and ISBN "magic links" can no longer contain
newlines; but they can contain and other non-newline whitespace.
* The 'mediawiki.action.edit' ResourceLoader module no longer generates the edit
toolbar, which has been moved to a separate 'mediawiki.toolbar' module. If you
relied on this behavior, update your scripts' dependencies.
* HTMLForm's 'vform' display style has been separated to a subclass. Therefore:
* HTMLForm::isVForm() is now deprecated.
* You can no longer do this:
$form = new HTMLForm( … );
$form->setDisplayFormat( 'vform' ); // throws exception
Instead, do this:
$form = HTMLForm::factory( 'vform', … );
* Deprecated Revision methods getRawUser(), getRawUserText() and getRawComment().
* BREAKING CHANGE: mediawiki.user.generateRandomSessionId:
The alphabet of the prior string returned was A-Za-z0-9 and now it is 0-9A-F
* (T87504) Avoid serving SVG background-images in CSS for Opera 12, which
renders them incorrectly when combined with border-radius or background-size.
* Removed maintenance script dumpSisterSites.php.
* DatabaseBase class constructors must be called using the array argument style.
Ideally, DatabaseBase:factory() should be used instead in most cases.
* Deprecated ParserOutput::addSecondaryDataUpdate and ParserOutput::getSecondaryDataUpdates.
This is a hard deprecation, with getSecondaryDataUpdates returning an empty array and
addSecondaryDataUpdate throwing an exception. These functions will be removed in 1.26,
since they interfere with caching of ParserOutput objects.
* Introduced new hook 'SecondaryDataUpdates' that allows extensions to inject custom updates.
* Introduced new hook 'OpportunisticLinksUpdate' that allows extensions to perform
updates when a page is re-rendered.
* EditPage::attemptSave has been modified not to call handleStatus itself and
instead just returns the Status object. Extension calling it should be aware of
this.
* Removed class DBObject. (unused since 1.10)
* wfDiff() is deprecated.
* The -m (maximum replication lag) option of refreshLinks.php was removed.
It had no effect since MediaWiki 1.18 and should be removed from any cron
jobs or similar scripts you may have set up.
* (T85864) The following messages no longer support raw html: redirectto,
thisisdeleted, viewdeleted, editlink, retrievedfrom, version-poweredby-others,
retrievedfrom, thisisdeleted, viewsourcelink, lastmodifiedat, laggedslavemode,
protect-summary-cascade
* All BloomCache related code has been removed. This was largely experimental.
* $wgResourceModuleSkinStyles no longer supports per-module local or remote paths. They
can only be set for the entire skin.
* Removed global function swap(). (deprecated since 1.24)
* Deprecated the ".php5" file extension entry points and the $wgScriptExtension
configuration variable. Refer to the ".php" files instead. If you want
".php5" URLs to continue to work, set up redirects. In Apache, this can be
done by enabling mod_rewrite and adding the following rules to your
configuration:
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)\.php5 $1.php [R=301,L]
* The global importScriptURI and importStylesheetURI functions, as well as the
loadedScripts object, from wikibits.js (deprecated since 1.17) now emit
warnings through mw.log.warn when accessed.
== Compatibility ==
MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
HHVM 3.3.0.
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 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
* Microsoft SQL Server 2005 (9.00.1399)
== Upgrading ==
1.25 has several database changes since 1.24, 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 1.24.x and older releases, see HISTORY.
== Online documentation ==
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):
https://www.mediawiki.org/wiki/Documentation
== Mailing list ==
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.

* (bug 36356) Add space between two feed links.
* (bug 63269) Email notifications were not correctly handling the
[[MediaWiki:Helppage]] message being set to a full URL. This is a regression
from the 1.22.5 point release, which made the default value for it a URL.
If you customized [[MediaWiki:Enotif body]] (the text of email notifications),
you'll need to edit it locally to include the URL via the new variable
$HELPPAGE instead of the parser functions fullurl and canonicalurl; otherwise
you don't have to do anything.
* Add missing uploadstash.us_props for PostgreSQL.
* (bug 56047) Fixed stream wrapper in PhpHttpRequest.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-

(bug 58153) Make MySQLi work with non standard port.
(bug 53887) Reintroduced a link to help pages in the default sidebar, that any sysop can customize by editing MediaWiki:Sidebar locally.

Everyone can help with the shared documentation by translating: https://www.mediawiki.org/wiki/Special:Translate/agg-Help_pages .
(bug 53888) Corrected a regression in 1.22 which introduced red links on the login page. If you previously installed 1.22.x and have created a local page to make the red link blue, write its title as in MediaWiki:helplogin-url if you didn't already. Otherwise, you don't need to do anything, but you can translate the help page at https://www.mediawiki.org/wiki/Help:Logging_in

Configuration changes in 1.20
$wgGitRepositoryViewers defines a mapping from Git remote repository to the Gitweb instance URL used in Special:Version.
$wgUsePathInfo = true; is no longer needed to make $wgArticlePath work on servers using like nginx, lighttpd, and apache over fastcgi. MediaWiki now always extracts path info from REQUEST_URI if it's available.

New variables $wgDBssl and $wgDBcompress to enable SSL and compression for database connections, if either are available for the selected DB type.
$wgUseCombinedLoginLink now defaults to false, making MediaWiki output separate login and create account links by default.
New features in 1.20
Added TitleIsAlwaysKnown hook which gets called when determining if a page exists.

== MediaWiki 1.17.1 ==
2011-11-24
This a maintenance and security release of the MediaWiki 1.17 branch.
=== Security changes ===
* (bug 32276) Skins were generating output using the internal page title which
would allow anonymous users to determine wheter a page exists, potentially
leaking private data. In fact, the curid and oldid request parameters would
allow page titles to be enumerated even when they are not guessable.
* (bug 32616) action=ajax requests were dispatched to the relevant internal
functions without any read permission checks being done. This could lead to
data leakage on private wikis.
Summary of selected changes in 1.17
Selected changes since MediaWiki 1.16 that may be of interest:
A new installer has been introduced. It has a wizard-style interface which is translated into many languages. Many shortcomings in the old installer were addressed with this rewrite. Note that it is no longer required for the config directory to be made writable by the webserver. Instead the generated LocalSettings.php file is offered as a download, which you must then upload to the wiki's base directory.
ResourceLoader, a new framework for delivering client-side resources such as JavaScript and CSS, has been introduced. These resources are now delivered through the new entry point script "load.php", instead of as static files served directly by the web server. This allows minification, compression and client-side caching to be used more effectively, which should provide a net performance improvement for most users.
Category sorting has been improved.
Sorting is now case insensitive.
Sub-categories, pages and files can now be paged separately.
When several pages are given the same sort key, they sort by their names instead of randomly.
The lowest supported version of PHP is now 5.2.3. If necessary, please upgrade PHP prior to upgrading MediaWiki.
Summary of selected changes in 1.16
Selected changes since MediaWiki 1.15 that may be of interest:
Watchlists now have RSS/Atom feeds. RSS feeds generally are now hidden, since Atom is a better protocol and is supported by virtually all clients.
It's now possible to block users from sending email via Special:Emailuser.
The maintenance script system was overhauled. Most maintenance scripts now have a useful help page when you run them with --help.
AdminSettings.php is no longer required in order to run maintenance scripts. You can just set $wgDBadminuser and $wgDBadminpassword in your LocalSettings.php instead.
The preferences system was overhauled. Preferences are stored in a more compact format. Changes to site default preferences will automatically affect all users who have not chosen a different preference.
Support for SQLite was improved. Some broken features were fixed, and it now has an efficient full-text search.
The user groups ACL system was improved by allowing rights to be revoked, instead of just granted.
A new localisation caching system was introduced, which will make MediaWiki faster for almost everyone, especially when lots of extensions are enabled.
By default, this new system makes a lot of database queries. If your database is particularly slow, or if your system administrator limits your query count, or if you want to squeeze as much performance as possible out of Mediawiki, set $wgCacheDirectory to a writable path on the local filesystem. Make sure you have the DBA extension for PHP installed, this will improve performance further.
== MediaWiki 1.15.5 ==

This is a security and maintenance release.
MediaWiki is now using a "continuous integration" development model with
quarterly snapshot releases. The latest development code is always kept
"ready to run", and in fact runs our own sites on Wikipedia.
Release branches will continue to receive security updates for about a year
from first release, but nonessential bugfixes and feature developments
will be made on the development trunk and appear in the next quarterly release.
Those wishing to use the latest code instead of a branch release can obtain
it from source control: http://www.mediawiki.org/wiki/Download_from_SVN
This is a security and bugfix release of MediaWiki 1.15.4.
Two security vulnerabilities were discovered.
Kuriaki Takashi discovered an XSS vulnerability in MediaWiki. It
affects Internet Explorer clients only. The issue is presumed to
affect all recent versions of IE, it has been confirmed on IE 6 and 8.
Noncompliant CSS parsing behaviour in Internet Explorer allows
attackers to construct CSS strings which are treated as safe by
previous versions of MediaWiki, but are decoded to unsafe strings by
Internet Explorer. Full details can be found at:
https://bugzilla.wikimedia.org/show_bug.cgi?id=23687
A CSRF vulnerability was discovered in our login interface. Although
regular logins are protected as of 1.15.3, it was discovered that the
account creation and password reset features were not protected from
CSRF. This could lead to unauthorised access to private wikis. See
https://bugzilla.wikimedia.org/show_bug.cgi?id=23371 for details.
These vulnerabilities are serious and all users are advised to
upgrade. Remember that CSRF and XSS vulnerabilities can be used even
against firewall-protected intranet installations, as long as the
attacker can guess the URL.
This is a security and bugfix release of MediaWiki 1.15.3 and MediaWiki
1.16.0beta2.
MediaWiki was found to be vulnerable to login CSRF. An attacker who
controls a user account on the target wiki can force the victim to log
in as the attacker, via a script on an external website. If the wiki is
configured to allow user scripts, say with "$wgAllowUserJs = true" in
LocalSettings.php, then the attacker can proceed to mount a
phishing-style attack against the victim to obtain their password.
Even without user scripting, this attack is a potential nuisance, and so
all public wikis should be upgraded if possible.
Our fix includes a breaking change to the API login action. Any clients
using it will need to be updated. We apologise for making such a
disruptive change in a minor release, but we feel that security is
paramount.

Two security issues were discovered:
A CSS validation issue was discovered which allows editors to display
external images in wiki pages. This is a privacy concern on public
wikis, since a malicious user may link to an image on a server they
control, which would allow that attacker to gather IP addresses and
other information from users of the public wiki. All sites running
publicly-editable MediaWiki installations are advised to upgrade. All
versions of MediaWiki (prior to this one) are affected.
A data leakage vulnerability was discovered in thumb.php which affects
wikis which restrict access to private files using img_auth.php, or
some similar scheme. All versions of MediaWiki since 1.5 are affected.
Deleting thumb.php is a suitable workaround for private wikis which do
not use $wgThumbnailScriptPath or $wgLocalRepo['thumbScriptUrl'].
Alternatively, you can upgrade to MediaWiki 1.15.2 or backport the
patch below to whatever version of MediaWiki you are using.
