Whether to allow security-sensitive operations when re-authentication is not possible.

If AuthManager::canAuthenticateNow() is false (e.g. the current SessionProvider is not able to change users, such as when OAuth is in use), AuthManager::securitySensitiveOperationStatus() cannot sensibly return SEC_REAUTH. Setting an operation true here will have it return SEC_OK in that case, while setting it false will have it return SEC_FAIL.

◆ $wgAllowSiteCSSOnRestrictedPages

$wgAllowSiteCSSOnRestrictedPages = false

Whether to allow site-wide CSS (MediaWiki:Common.css and friends) on restricted pages like Special:UserLogin or Special:Preferences where JavaScript is disabled for security reasons.

As it is possible to execute JavaScript through CSS, setting this to true opens up a potential security hole. Some sites may "skin" their wiki by using site-wide CSS, causing restricted pages to look unstyled and different from the rest of the site.

◆ $wgAntivirusSetup

$wgAntivirusSetup

Initial value:

= [
 
    # setup for clamav
    'clamav' => [
        'command' => 'clamscan --no-summary ',
        'codemap' => [
            "0" => AV_NO_VIRUS, # no virus
            "1" => AV_VIRUS_FOUND, # virus found
            "52" => AV_SCAN_ABORTED, # unsupported file format (probably immune)
            "*" => AV_SCAN_FAILED, # else scan failed
        ],
        'messagepattern' => '/.*?:(.*)/sim',
    ],
]

Configuration for different virus scanners.

This an associative array of associative arrays. It contains one setup array per known scanner type. The entry is selected by $wgAntivirus, i.e. valid values for $wgAntivirus are the keys defined in this array.

The configuration array for each scanner contains the following keys: "command", "codemap", "messagepattern":

"command" is the full command to call the virus scanner - f will be replaced with the name of the file to scan. If not present, the filename will be appended to the command. Note that this must be overwritten if the scanner is not in the system path; in that case, please set $wgAntivirusSetup[$wgAntivirus]['command'] to the desired command with full path.

"codemap" is a mapping of exit code to return codes of the detectVirus function in SpecialUpload.

An exit code mapped to AV_SCAN_FAILED causes the function to consider the scan to be failed. This will pass the file if $wgAntivirusRequired is not set.
An exit code mapped to AV_SCAN_ABORTED causes the function to consider the file to have an unsupported format, which is probably immune to viruses. This causes the file to pass.
An exit code mapped to AV_NO_VIRUS will cause the file to pass, meaning no virus was found.
All other codes (like AV_VIRUS_FOUND) will cause the function to report a virus.
You may use "*" as a key in the array to catch all exit codes not mapped otherwise.

"messagepattern" is a perl regular expression to extract the meaningful part of the scanners output. The relevant part should be matched as group one (\1). If not defined or the pattern does not match, the full message is shown to the user.

Definition at line 8618 of file DefaultSettings.php.

◆ $wgApiFrameOptions

$wgApiFrameOptions = 'DENY'

Disallow framing of API pages directly, by setting the X-Frame-Options header.

Since the API returns CSRF tokens, allowing the results to be framed can compromise your user's account security. Options are:

'DENY': Do not allow framing. This is recommended for most wikis.
'SAMEORIGIN': Allow framing by pages on the same domain.
false: Allow all framing. Note: $wgBreakFrames will override this for human formatted API output.

Definition at line 8663 of file DefaultSettings.php.

◆ $wgAPIMetaModules

$wgAPIMetaModules = []

API Query meta module extensions.

Associative array mapping meta module name to module specs (see $wgAPIModules). Extension modules may override the core modules.

See ApiQuery::$QueryMetaModules for a list of the core meta modules.

Definition at line 8627 of file DefaultSettings.php.

◆ $wgAPIModules

$wgAPIModules = []

API module extensions.

Associative array mapping module name to modules specs; Each 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.

That factory function will be called with two parameters, the parent module (an instance of ApiBase, usually ApiMain) and the name the module was registered under. The return value must be an instance of the class given in the 'class' field.

For backward compatibility, the module spec may also be a simple string containing the module's class name. In that case, the class' constructor will be called with the parent module and module name as parameters, as described above.

Examples for registering API modules:

$wgAPIModules['foo'] = 'ApiFoo';
$wgAPIModules['bar'] = [
  'class' => ApiBar::class,
  'factory' => function( $main, $name ) { ... }
];
$wgAPIModules['xyzzy'] = [
  'class' => ApiXyzzy::class,
  'factory' => [ XyzzyFactory::class, 'newApiModule' ]
];

Extension modules may override the core modules. See ApiMain::$Modules for a list of the core modules.

Definition at line 8609 of file DefaultSettings.php.

◆ $wgAPIPropModules

$wgAPIPropModules = []

API Query prop module extensions.

Associative array mapping prop module name to module specs (see $wgAPIModules). Extension modules may override the core modules.

◆ $wgArticleCountMethod

$wgArticleCountMethod = 'link'

Method used to determine if a page in a content namespace should be counted as a valid article.

Redirect pages will never be counted as valid articles.

This variable can have the following values:

'any': all pages as considered as valid articles
'link': the page must contain a [[wiki link]] to be considered valid

secondaryauth: Array (keys ignored) of specifications for SecondaryAuthenticationProviders

◆ $wgAutopromote

$wgAutopromote

Initial value:

    'autoconfirmed' => [ '&',
        [ APCOND_EDITCOUNT, &$wgAutoConfirmCount ],
        [ APCOND_AGE, &$wgAutoConfirmAge ],
    ],
]

Array containing the conditions of automatic promotion of a user to specific groups.

The basic syntax for $wgAutopromote is:

$wgAutopromote = [
    'groupname' => cond,
    'group2' => cond2,
];

A cond may be:

a single condition without arguments: Note that Autopromote wraps a single non-array value into an array e.g. APCOND_EMAILCONFIRMED OR [ APCOND_EMAILCONFIRMED ]
a single condition with arguments: e.g. [ APCOND_EDITCOUNT, 100 ]
a set of conditions: e.g. ‘[ 'operand’, cond1, cond2, ... ]`

When constructing a set of conditions, the following conditions are available:

& (AND): promote if user matches ALL conditions
| (OR): promote if user matches ANY condition
^ (XOR): promote if user matches ONLY ONE OF THE CONDITIONS
! (NOT): promote if user matces NO condition
[ APCOND_EMAILCONFIRMED ]: true if user has a confirmed e-mail
[ APCOND_EDITCOUNT, number of edits ]: true if user has the at least the number of edits as the passed parameter
[ APCOND_AGE, seconds since registration ]: true if the length of time since the user created his/her account is at least the same length of time as the passed parameter
[ APCOND_AGE_FROM_EDIT, seconds since first edit ]: true if the length of time since the user made his/her first edit is at least the same length of time as the passed parameter
[ APCOND_INGROUPS, group1, group2, ... ]: true if the user is a member of each of the passed groups
[ APCOND_ISIP, ip ]: true if the user has the passed IP address
[ APCOND_IPINRANGE, range ]: true if the user has an IP address in the range of the passed parameter
[ APCOND_BLOCKED ]: true if the user is sitewide blocked
[ APCOND_ISBOT ]: true if the user is a bot
similar constructs can be defined by extensions

The sets of conditions are evaluated recursively, so you can use nested sets of conditions linked by operands.

Note that if $wgEmailAuthentication is disabled, APCOND_EMAILCONFIRMED will be true for any user who has provided an e-mail address.

◆ $wgAutopromoteOnce

$wgAutopromoteOnce

◆ $wgBlockCIDRLimit

$wgBlockCIDRLimit

Initial value:

= [
    'IPv4' => 16, # Blocks larger than a /16 (64k addresses) will not be allowed
    'IPv6' => 19,
]

Limits on the possible sizes of range blocks.

CIDR notation is hard to understand, it's easy to mistakenly assume that a /1 is a small range and a /31 is a large range. For IPv4, setting a limit of half the number of bits avoids such errors, and allows entire ISPs to be blocked using a small number of range blocks.

For IPv6, RFC 3177 recommends that a /48 be allocated to every residential customer, so range blocks larger than /64 (half the number of bits) will plainly be required. RFC 4692 implies that a very large ISP may be allocated a /19 if a generous HD-Ratio of 0.8 is used, so we will use that as our limit. As of 2012, blocking the whole world would require a /4 range.

◆ $wgCategoryCollation

$wgCategoryCollation = 'uppercase'

Specify how category names should be sorted, when listed on a category page.

A sorting scheme is also known as a collation.

Available values are:

uppercase: Converts the category name to upper case, and sorts by that.
identity: Does no conversion. Sorts by binary value of the string.
uca-default: Provides access to the Unicode Collation Algorithm with the default element table. This is a compromise collation which sorts all languages in a mediocre way. However, it is better than "uppercase".

To use the uca-default collation, you must have PHP's intl extension installed. See https://www.php.net/manual/en/intl.setup.php . The details of the resulting collation will depend on the version of ICU installed on the server.

After you change this, you must run maintenance/updateCollation.php to fix the sort keys in the database.

Extensions can define there own collations by subclassing Collation and using the Collation::factory hook.

◆ $wgCdnReboundPurgeDelay

$wgCdnReboundPurgeDelay = 0

If set, any SquidPurge call on a URL or URLs will send a second purge no less than this many seconds later via the job queue.

This requires delayed job support. This should be safely higher than the 'max lag' value in $wgLBFactoryConf, so that replica DB lag does not cause page to be stuck in stales states in CDN.

This also fixes race conditions in two-tiered CDN setups (e.g. cdn2 => cdn1 => MediaWiki). If a purge for a URL reaches cdn2 before cdn1 and a request reaches cdn2 for that URL, it will populate the response from the stale cdn1 value. When cdn1 gets the purge, cdn2 will still be stale. If the rebound purge delay is safely higher than the time to relay a purge to all nodes, then the rebound purge will clear cdn2 after cdn1 was cleared.

If an array, can have parameters: 'default-src' If true or array (of additional urls) will set a default-src directive, which limits what places things can load from. If false or not set, will send a default-src directive allowing all sources. 'includeCORS' If true or not set, will include urls from $wgCrossSiteAJAXdomains as an allowed load sources. 'unsafeFallback' Add unsafe-inline as a script source, as a fallback for browsers that do not understand nonce-sources [default on]. 'useNonces' Require nonces on all inline scripts. If disabled and 'unsafeFallback' is on, then all inline scripts will be allowed [default true]. 'script-src' Array of additional places that are allowed to have JS be loaded from. 'object-src' Array or string of where to load objects from. unset/true means 'none'. False means omit. (Since 1.35) 'report-uri' true to use MW api [default], false to disable, string for alternate uri

Database load balancer This is a two-dimensional array, an array of server info structures Fields are:

host: Host name
dbname: Default database name
user: DB user
password: DB password
type: DB type
driver: DB driver (when there are multiple drivers)
load: Ratio of DB_REPLICA load, must be >=0, the sum of all loads must be >0. If this is zero for any given server, no normal query traffic will be sent to it. It will be excluded from lag checks in maintenance scripts. The only way it can receive traffic is if groupLoads is used.
groupLoads: (optional) Array of load ratios, the key is the query group name. A query may belong to several groups, the most specific group defined here is used.
flags: (optional) Bit field of properties:
- DBO_DEFAULT: Transactionalize web requests and use autocommit otherwise
- DBO_DEBUG: Equivalent of $wgDebugDumpSql
- DBO_SSL: Use TLS connection encryption if available
- DBO_COMPRESS: Use protocol compression with database connections
- DBO_PERSISTENT: Enables persistent database connections
max lag: (optional) Maximum replication lag before a replica DB goes out of rotation
is static: (optional) Set to true if the dataset is static and no replication is used.
cliMode: (optional) Connection handles will not assume that requests are short-lived nor that INSERT..SELECT can be rewritten into a buffered SELECT and INSERT. This is what DBO_DEFAULT uses to determine when a web request is present. [Default: uses value of $wgCommandLineMode]

These and any other user-defined properties will be assigned to the mLBInfo member variable of the Database object.

Leave at false to use the single-server variables above. If you set this variable, the single-server variables will generally be ignored (except perhaps in some command-line scripts).

The first server listed in this array (with key 0) will be the master. The rest of the servers will be replica DBs. To prevent writes to your replica DBs due to accidental misconfiguration or MediaWiki bugs, set read_only=1 on all your replica DBs in my.cnf. You can set read_only mode at runtime using:

SET @@read_only=1;

Since the effect of writing to a replica DB is so damaging and difficult to clean up, we at Wikimedia set read_only=1 in my.cnf on all our DB servers, even our masters, and then set read_only=0 on masters at runtime.

◆ $wgEventRelayerConfig

$wgEventRelayerConfig

Initial value:

= [
    'default' => [
        'class' => EventRelayerNull::class,
    ]
]

Mapping of event channels (or channel categories) to EventRelayer configuration.

By setting up a PubSub system (like Kafka) and enabling a corresponding EventRelayer class that uses it, MediaWiki can broadcast events to all subscribers. Certain features like WAN cache purging and CDN cache purging will emit events to this system. Appropriate listers can subscribe to the channel and take actions based on the events. For example, a local daemon can run on each CDN cache node and perform local purges based on the URL purge channel events.

Some extensions may want to use "channel categories" so that different channels can also share the same custom relayer instance (e.g. when it's likely to be overriden). They can use EventRelayerGroup::getRelayer() based on the category but call notify() on various different actual channels. One reason for this would be that some system have very different performance vs durability needs, so one system (e.g. Kafka) may not be suitable for all uses.

The 'default' key is for all channels (or channel categories) without an explicit entry here.

This is for use from LocalSettings.php and legacy PHP-entrypoint extensions. In general, extensions should (only) declare this information in their extension.json file.

The 'name', 'path' and 'author' keys are required.

$wgExtensionCredits['other'][] = [
    'path' => __FILE__,
    'name' => 'Example extension',
    'namemsg' => 'exampleextension-name',
    'author' => [
        'Foo Barstein',

    'url' => 'https://example.org/example-extension/',
    'descriptionmsg' => 'exampleextension-desc',
    'license-name' => 'GPL-2.0-or-later',
];

The extensions are listed on Special:Version. This page also looks for a file named COPYING or LICENSE (optional .txt extension) and provides a link to view said file. When the 'license-name' key is specified, this file is interpreted as wikitext.

$type: One of 'specialpage', 'parserhook', 'variable', 'media', 'antispam', 'skin', 'api', or 'other', or any additional types as specified through the ExtensionTypes hook as used in SpecialVersion::getExtensionTypes().
name: Name of extension as an inline string instead of localizable message. Do not omit this even if 'namemsg' is provided, as it is used to override the path Special:Version uses to find extension's license info, and is required for backwards-compatibility with MediaWiki 1.23 and older.
namemsg (since MW 1.24): A message key for a message containing the extension's name, if the name is localizable. (For example, skin names usually are.)
author: A string or an array of strings. Authors can be linked using the regular wikitext link syntax. To have an internationalized version of "and others" show, add an element "...". This element can also be linked, for instance "[https://example ...]".
descriptionmsg: A message key or an an array with message key and parameters: ‘'descriptionmsg’ => 'exampleextension-desc',`
description: Description of extension as an inline string instead of localizable message (omit in favour of 'descriptionmsg').
license-name: Short name of the license (used as label for the link), such as "GPL-2.0-or-later" or "MIT" (https://spdx.org/licenses/ for a list of identifiers).

◆ $wgExtensionMessagesFiles

$wgExtensionMessagesFiles = []

Extension messages files.

Associative array mapping extension name to the filename where messages can be found. The file should contain variable assignments. Any of the variables present in languages/messages/MessagesEn.php may be defined, but $messages is the most common.

Variables defined in extensions will override conflicting variables defined in the core.

Since MediaWiki 1.23, use of this variable to define messages is discouraged; instead, store messages in JSON format and use $wgMessagesDirs. For setting other variables than $messages, $wgExtensionMessagesFiles should still be used. Use a DIFFERENT key because any entry having a key that also exists in $wgMessagesDirs will be ignored.

Extensions using the JSON message format can preserve backward compatibility with earlier versions of MediaWiki by using a compatibility shim, such as one generated by the generateJsonI18n.php maintenance script, listing it under the SAME key as for the $wgMessagesDirs entry.

Example:: $wgExtensionMessagesFiles['ConfirmEdit'] = __DIR__.'/ConfirmEdit.i18n.php';

Warning: Once you delete a namespace, the pages in that namespace will no longer be accessible. If you rename it, then you can access them through the new namespace name.

Custom namespaces should start at 100 to avoid conflicting with standard namespaces, and should always follow the even/odd main/talk pattern.

File backend structure configuration.

This is an array of file backend configuration arrays. Each backend configuration has the following parameters:

name : A unique name for the backend
class : The file backend class to use
wikiId : A unique string that identifies the wiki (container prefix)
lockManager : The name of a lock manager (see $wgLockManagers) [optional]
fileJournal : File journal configuration for FileJournal::__construct() [optional]

See FileBackend::__construct() for more details. Additional parameters are specific to the file backend class used. These settings should be global to all wikis when possible.

FileBackendMultiWrite::__construct() is augmented with a 'template' option that can be used in any of the values of the 'backends' array. Its value is the name of another backend in $wgFileBackends. When set, it pre-fills the array with all of the configuration of the named backend. Explicitly set values in the array take precedence.

There are two particularly important aspects about each backend:

a) Whether it is fully qualified or wiki-relative. By default, the paths of files are relative to the current wiki, which works via prefixing them with the current wiki ID when accessed. Setting 'domainId' forces the backend to be fully qualified by prefixing all paths with the specified value instead. This can be useful if multiple wikis need to share the same data. Note that 'name' is not part of any prefix and thus should not be relied upon for namespacing.
b) Whether it is only defined for some wikis or is defined on all wikis in the wiki farm. Defining a backend globally is useful if multiple wikis need to share the same data. One should be aware of these aspects when configuring a backend for use with any basic feature or plugin. For example, suppose an extension stores data for different wikis in different directories and sometimes needs to access data from a foreign wiki's directory in order to render a page on given wiki. The extension would need a fully qualified backend that is defined on all wikis in the wiki farm.

    "poweredby" => [
        "mediawiki" => [

            "alt" => "Powered by MediaWiki",
        ]
    ],
]

Abstract list of footer icons for skins in place of old copyrightico and poweredbyico code You can add new icons to the built in copyright or poweredby, or you can create a new block.

Though note that you may need to add some custom css to get good styling of new blocks in monobook. vector and modern should work without any special css.

$wgFooterIcons itself is a key/value array. The key is the name of a block that the icons will be wrapped in. The final id varies by skin; Monobook and Vector will turn poweredby into f-poweredbyico while Modern turns it into mw_poweredby. The value is either key/value array of icons or a string. In the key/value array the key may or may not be used by the skin but it can be used to find the icon and unset it or change the icon if needed. This is useful for disabling icons that are set by extensions. The value should be either a string or an array. If it is a string it will be output directly as html, however some skins may choose to ignore it. An array is the preferred format for the icon, the following keys are used:

src: An absolute url to the image to use for the icon, this is recommended but not required, however some skins will ignore icons without an image
srcset: optional additional-resolution images; see HTML5 specs
url: The url to use in the a element around the text or icon, if not set an a element will not be outputted
alt: This is the text form of the icon, it will be displayed without an image in skins like Modern or if src is not set, and will otherwise be used as the alt="" for the image. This key is required.
width and height: If the icon specified by src is not of the standard size you can specify the size of image to use with these keys. Otherwise they will default to the standard 88x31.

◆ $wgForceHTTPS

bool $wgForceHTTPS = false

If this is true, when an insecure HTTP request is received, always redirect to HTTPS.

This overrides and disables the preferhttps user preference, and it overrides $wgSecureLogin and the CanIPUseHTTPS hook.

$wgServer may be either https or protocol-relative. If $wgServer starts with "http://", an exception will be thrown.

If a reverse proxy or CDN is used to forward requests from HTTPS to HTTP, the request header "X-Forwarded-Proto: https" should be sent to suppress the redirect.

In addition to setting this to true, for optimal security, the web server should also be configured to send Strict-Transport-Security response headers.

◆ $wgForceUIMsgAsContentMsg

$wgForceUIMsgAsContentMsg = []

When translating messages with wfMessage(), it is not always clear what should be considered UI messages and what should be content messages.

For example, for the English Wikipedia, there should be only one 'mainpage', so when getting the link for 'mainpage', we should treat it as site content and call ->inContentLanguage()->text(), but for rendering the text of the link, we call ->text(). The code behaves this way by default. However, sites like the Wikimedia Commons do offer different versions of 'mainpage' and the like for different languages. This array provides a way to override the default behavior.

Example:: To allow language-specific main page and community portal:
$wgForceUIMsgAsContentMsg = [ 'mainpage', 'portal-url' ];

$wgForceUIMsgAsContentMsg

◆ $wgForeignFileRepos

$wgForeignFileRepos = []

Enable the use of files from one or more other wikis.

If you operate multiple wikis, you can declare a shared upload path here. Uploads to the local wiki will NOT be stored here - See $wgLocalFileRepo and $wgUploadDirectory for that.

The wiki will only consider the foreign repository if no file of the given name is found in the local repository (e.g. via [[File:..]] syntax).

◆ $wgForeignUploadTargets

$wgForeignUploadTargets = [ 'local' ]

Array of foreign file repo names (set in $wgForeignFileRepos above) that are allowable upload targets.

These wikis must have some method of authentication (i.e. CentralAuth), and be CORS-enabled for this wiki. The string 'local' signifies the default local file repository.

Example: $wgForeignUploadTargets = [ 'shared' ];

Definition at line 766 of file DefaultSettings.php.

◆ $wgFragmentMode

$wgFragmentMode = [ 'legacy', 'html5' ]

How should section IDs be encoded? This array can contain 1 or 2 elements, each of them can be one of:

'html5' is modern HTML5 style encoding with minimal escaping. Displays Unicode characters in most browsers' address bars.
'legacy' is old MediaWiki-style encoding, e.g. 啤酒 turns into .E5.95.A4.E9.85.92

The first element of this array specifies the primary mode of escaping IDs. This is what users will see when they e.g. follow an [[#internal link]] to a section of a page.

The optional second element defines a fallback mode, useful for migrations. If present, it will direct MediaWiki to add empty s to every section with its id attribute set to fallback encoded title so that links using the previous encoding would still work.

Example: you want to migrate your wiki from 'legacy' to 'html5'

On the first step, set this variable to [ 'legacy', 'html5' ]. After a while, when all caches (parser, HTTP, etc.) contain only pages generated with this setting, flip the value to [ 'html5', 'legacy' ]. This will result in all internal links being generated in the new encoding while old links (both external and cached internal) will still work. After a long time, you might want to ditch backwards compatibility and set it to [ 'html5' ]. After all, pages get edited, breaking incoming links no matter which fragment mode is used.

imageWidth: Width of the cells containing images in galleries (in "px")
imageHeight: Height of the cells containing images in galleries (in "px")
captionLength: Length to truncate filename to in caption when using "showfilename". A value of 'true' will truncate the filename to one line using CSS and will be the behaviour after deprecation.

◆ $wgGenerateThumbnailOnParse

bool $wgGenerateThumbnailOnParse = true

Render thumbnails while parsing wikitext.

If set to false, then the Parser will output valid thumbnail URLs without generating or storing the thumbnail files. This can significantly speed up processing on the web server. The site admin needs to configure a 404 handler in order for the URLs in question to regenerate the thumbnails in question on-demand. This can enable concurrency and also save computing resources as not every resolution of every image on every page is accessed between re-parses of the article. For example, re-parses triggered by bot edits, or cascading updates from template edits.

If you use $wgLocalFileRepo, then you will also need to set the following:

$wgLocalFileRepo['transformVia404'] = true;

◆ $wgGroupPermissions

$wgGroupPermissions = []

Permission keys given to users in each group.

This is an array where the keys are all groups and each value is an array of the format (right => boolean).

The second format is used to support per-namespace permissions. Note that this feature does not fully work for all permission types.

All users are implicitly in the '*' group including anonymous visitors; logged-in users are all implicitly in the 'user' group. These will be combined with the permissions of all groups that a given user is listed in in the user_groups table.

Note: Don't set $wgGroupPermissions = []; unless you know what you're doing! This will wipe all permissions, and may mean that your users are unable to perform certain essential tasks or access new functionality when new permissions are introduced and default grants established.

Functionality to make pages inaccessible has not been extensively tested for security. Use at your own risk!

◆ $wgHTCPRouting

$wgHTCPRouting = []

Routing configuration for HTCP multicast purging.

Add elements here to enable HTCP and determine which purges are sent where. If set to an empty array, HTCP is disabled.

Each key in this array is a regular expression to match against the purged URL, or an empty string to match all URLs. The purged URL is matched against the regexes in the order specified, and the first rule whose regex matches is used, all remaining rules will thus be ignored.

Example configuration to send purges for upload.wikimedia.org to one: multicast group and all other purges to another:
$wgHTCPRouting = [

'|^https?://upload\\.wikimedia\\.org|' => [

'host' => '239.128.0.113',

'port' => 4827,

You can also pass an array of hosts to send purges too. This is useful when you have several multicast groups or unicast address that should receive a given purge. Multiple hosts support was introduced in MediaWiki 1.22.

Example of sending purges to multiple hosts:: $wgHTCPRouting = [

Add a preconnect link for browsers to a remote FileRepo host.

This is an optional performance enhancement designed for wiki farm where $wgForeignFileRepos or $wgLocalFileRepo is set to serve thumbnails from a separate hostname (e.g. not local /w/images). The feature expects at most a single remote hostname to be used.

If multiple foreign repos are registered that serve images from different hostnames, only the first will be preconnected.

This may cause unneeded HTTP connections in browsers on wikis where a foreign repo is enabled but where a local repo is more commonly used.

This is used to interpret the request URL for requests to img_auth.php that do not match the base upload path. If false, "{$wgScriptPath}/img_auth.php" is used.

Normally, requests to img_auth.php have a REQUEST_URI which matches $wgUploadPath, and in that case, setting this should not be necessary. This variable is used in case img_auth.php is accessed via a different path than $wgUploadPath.

◆ $wgImgAuthUrlPathMap

Map of relative URL directories to match to internal mwstore:// base storage paths.

For img_auth.php requests, everything after "img_auth.php/" is checked to see if starts with any of the prefixes defined here. The prefixes should not overlap. The prefix that matches has a corresponding storage path, which the rest of the URL is assumed to be relative to. The file at that path (or a 404) is send to the client.

Example: $wgImgAuthUrlPathMap['/timeline/'] = 'mwstore://local-fs/timeline-render/'; The above maps ".../img_auth.php/timeline/X" to "mwstore://local-fs/timeline-render/". The name "local-fs" should correspond by name to an entry in $wgFileBackends.

◆ $wgImportSources

$wgImportSources = []

List of interwiki prefixes for wikis we'll accept as sources for Special:Import and API action=import.

Since complete page history can be imported, these should be 'trusted'.

This can 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, e.g.

    'wikipedia' => [ 'cs', 'en', 'fr', 'zh' ],
    'wikispecies',
    'wikia' => [ 'animanga', 'brickipedia', 'desserts' ],

The meaning of "work items" varies per job, but typically would be something like "pages to update". A single job may have a variable number of work items, as is the case with batch jobs. This is used by runJobs.php and not jobs run via $wgJobRunRate. These settings should be global to all wikis.

◆ $wgJobQueueIncludeInMaxLagFactor

$wgJobQueueIncludeInMaxLagFactor = false

Whether to include the number of jobs that are queued for the API's maxlag parameter.

The total number of jobs will be divided by this to get an estimated second of maxlag. Typically bots backoff at maxlag=5, so setting this to the max number of jobs that should be in your queue divided by 5 should have the effect of stopping bots once that limit is hit.

◆ $wgJobRunRate

$wgJobRunRate = 1

Number of jobs to perform per request.

May be less than one in which case jobs are performed probabalistically. If this is zero, jobs will not be done during ordinary apache requests. In this case, maintenance/runJobs.php should be run periodically.

◆ $wgJobSerialCommitThreshold

float bool $wgJobSerialCommitThreshold = false

Make job runners commit changes for replica DB-lag prone jobs one job at a time.

This is useful if there are many job workers that race on replica DB lag checks. If set, jobs taking this many seconds of DB write time have serialized commits.

Note that affected jobs may have worse lock contention. Also, if they affect several DBs at once they may have a smaller chance of being atomic due to the possibility of connection loss while queueing up to commit. Affected jobs may also fail due to the commit lock acquisition timeout.

$wgJpegPixelFormat = 'yuv420'

At default setting of 'yuv420', JPEG thumbnails will use 4:2:0 chroma subsampling to reduce file size, at the cost of possible color fringing at sharp edges.

See https://en.wikipedia.org/wiki/Chroma_subsampling

Supported values: false - use scaling system's default (same as pre-1.27 behavior) 'yuv444' - luma and chroma at same resolution 'yuv422' - chroma at 1/2 resolution horizontally, full vertically 'yuv420' - chroma at 1/2 resolution in both dimensions

Warning: Don't use any of MediaWiki's deprecated language codes listed in LanguageCode::getDeprecatedCodeMapping or $wgDummyLanguageCodes, like "no" for Norwegian (use "nb" instead). If you do, things will break unexpectedly.

This defines the default interface language for all users, but users can change it in their preferences.

Use this when converting a wiki from MediaWiki 1.4 or earlier to UTF-8 without the burdensome mass conversion of old text data.

Note: This DOES NOT touch any fields other than old_text. Titles, comments, user names, etc still must be converted en masse in the database before continuing as a UTF-8 wiki.

If this is set to false, old code using deprecated variables will no longer work.

Example of legacy code:: if ( window.wgRestrictionEdit ) { ... }

◆ $wgLegalTitleChars

$wgLegalTitleChars = " %!\"$&'()*,\\-.\\/0-9:;=?@A-Z\\\\^_`a-z~\\x80-\\xFF+"

Allowed title characters – regex character class Don't change this unless you know what you're doing.

Problematic punctuation:

[]{}|# Are needed for link syntax, never enable these
<> Causes problems with HTML escaping, don't use
% Enabled by default, minor problems with path to query rewrite rules, see below
+ Enabled by default, but doesn't work with path to query rewrite rules, corrupted by apache
? Enabled by default, but doesn't work with path to PATH_INFO rewrites

All three of these punctuation problems can be avoided by using an alias, instead of a rewrite rule of either variety.

The problem with % is that when using a path to query rewrite rule, URLs are double-unescaped: once by Apache's path conversion code, and again by PHP. So %253F, for example, becomes "?". Our code does not double-escape to compensate for this, indeed double escaping would break if the double-escaped title was passed in the query string rather than the path. This is a minor security issue because articles can be created such that they are hard to view or edit.

In some rare cases you may wish to remove + for compatibility with old links.

◆ $wgLocalFileRepo

$wgLocalFileRepo = false

File repository structures.

$wgLocalFileRepo is a single repository structure, and $wgForeignFileRepos is an array of such structures. Each repository structure is an associative array of properties configuring the repository.

Properties required for all repos:

class The class name for the repository. May come from the core or an extension. The core repository classes are FileRepo, LocalRepo, ForeignDBRepo.
name A unique name for the repository (but $wgLocalFileRepo should be 'local'). The name should consist of alpha-numeric characters.
backend A file backend name (see $wgFileBackends).

For most core repos:

zones Associative array of zone names that each map to an array with: container : backend container name the zone is in directory : root path within container for the zone url : base URL to the root of the zone urlsByExt : map of file extension types to base URLs (useful for using a different cache for videos) Zones default to using "<repo name>-<zone name>" as the container name and default to using the container root as the zone's root directory. Nesting of zone locations within other zones should be avoided.
url Public zone URL. The 'zones' settings take precedence.

hashLevels The number of directory levels for hash-based division of files.

             Set this to 0 if you do not want MediaWiki to divide your images
             directory into many subdirectories.

             It is recommended to leave this enabled. In previous versions of
             MediaWiki, some users set this to false to allow images to be added to
             the wiki by copying them into $wgUploadDirectory and then running
             maintenance/rebuildImages.php to register them in the database.
             This is no longer supported, use maintenance/importImages.php instead.

             Default: 2.

deletedHashLevels Optional 'hashLevels' override for the 'deleted' zone.
thumbScriptUrl The URL for thumb.php (optional, not recommended)
transformVia404 Whether to skip media file transformation on parse and rely on a 404 handler instead.
initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE], determines whether filenames implicitly start with a capital letter. The current implementation may give incorrect description page links when the local $wgCapitalLinks and initialCapital are mismatched.
pathDisclosureProtection May be 'paranoid' to remove all parameters from error messages, 'none' to leave the paths in unchanged, or 'simple' to replace paths with placeholders. Default for LocalRepo is 'simple'.
fileMode This allows wikis to set the file mode when uploading/moving files. Default is 0644.
directory The local filesystem directory where public files are stored. Not used for some remote repos.
thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
isPrivate Set this if measures should always be taken to keep the files private. One should not trust this to assure that the files are not web readable; the server configuration should be done manually depending on the backend.

These settings describe a foreign MediaWiki installation. They are optional, and will be ignored for local repositories:

descBaseUrl URL of image description pages, e.g. https://en.wikipedia.org/wiki/File:
scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g. https://en.wikipedia.org/w
articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
fetchDescription Fetch the text of the remote file description page and display them on the local wiki.
abbrvThreshold File names over this size will use the short form of thumbnail names. Short thumbnail names only have the width, parameters, and the extension.

ForeignDBRepo:

dbType, dbServer, dbUser, dbPassword, dbName, dbFlags equivalent to the corresponding member of $wgDBservers
tablePrefix Table prefix, the foreign wiki's $wgDBprefix
hasSharedCache Set to true if the foreign wiki's $wgMainCacheType is identical to, and accessible from, this wiki.

ForeignAPIRepo:

apibase Use for the foreign API's URL
apiThumbCacheExpiry How long to locally cache thumbs for

If you leave $wgLocalFileRepo set to false, Setup will fill in appropriate values. Otherwise, set $wgLocalFileRepo to a repository structure as described above. If you set $wgUseInstantCommons to true, it will add an entry for Commons. If you set $wgForeignFileRepos to an array of repository structures, those will be searched after the local file repo. Otherwise, you will only have access to local media files.

Localisation cache configuration.

Used by Language::getLocalisationCache() to decide how to construct the LocalisationCache instance. Associative array with keys:

class: The class to use for constructing the LocalisationCache object. This may be overridden by extensions to a subclass of LocalisationCache. Sub classes are expected to still honor the 'storeClass', 'storeDirectory' and 'manualRecache' options where applicable.

storeClass: Which LCStore class implementation to use. This is optional. The default LocalisationCache class offers the 'store' option as abstraction for this.

store: How and where to store localisation cache data. This option is ignored if 'storeClass' is explicitly set to a class name. Must be one of:

'detect' (default): Automatically select 'files' if 'storeDirectory' or $wgCacheDirectory is set, and fall back to 'db' otherwise.
'files': Store in $wgCacheDirectory as CDB files.
'array': Store in $wgCacheDirectory as PHP static array files.
'db': Store in the l10n_cache database table.

storeDirectory: If the selected LCStore class puts its data in files, then it will use this directory. If set to false (default), then $wgCacheDirectory is used instead.

manualRecache: Set this to true to disable cache updates on web requests. Use maintenance/rebuildLocalisationCache.php instead.

The logging system has two levels: an event type, which describes the general category and can be viewed as a named subset of all logs; and an action, which is a specific kind of event that can exist in that log type.

Note that code should call LogPage::validTypes() to get a list of valid log types instead of checking the global variable.

◆ $wgMainCacheType

$wgMainCacheType = CACHE_NONE

Main cache type.

This should be a cache with fast access, but it may have limited space. By default, it is disabled, since the stock database cache is not fast enough to make it worthwhile.

The options are:

CACHE_ANYTHING: Use anything, as long as it works
CACHE_NONE: Do not cache
CACHE_DB: Store cache objects in the DB
CACHE_MEMCACHED: MemCached, must specify servers in $wgMemCachedServers
CACHE_ACCEL: APC, APCU or WinCache

◆ $wgMainStash

$wgMainStash = 'db-replicated'

The object store type of the main stash.

This store should be a very fast storage system optimized for holding lightweight data like incrementable hit counters and current user activity. The store should replicate the dataset among all data-centers. Any add(), merge(), lock(), and unlock() operations should maintain "best effort" linearizability; as long as connectivity is strong, latency is low, and there is no eviction pressure prompted by low free space, those operations should be linearizable. In terms of PACELC (https://en.wikipedia.org/wiki/PACELC_theorem), the store should act as a PA/EL distributed system for these operations. One optimization for these operations is to route them to a "primary" data-center (e.g. one that serves HTTP POST) for synchronous execution and then replicate to the others asynchronously. This means that at least calls to these operations during HTTP POST requests would quickly return.

All other operations, such as get(), set(), delete(), changeTTL(), incr(), and decr(), should be synchronous in the local data-center, replicating asynchronously to the others. This behavior can be overriden by the use of the WRITE_SYNC and READ_LATEST flags.

The store should preferably have eventual consistency to handle network partitions.

Modules that rely on the stash should be prepared for:

add(), merge(), lock(), and unlock() to be slower than other write operations, at least in "secondary" data-centers (e.g. one that only serves HTTP GET/HEAD)
Other write operations to have race conditions accross data-centers
Read operations to have race conditions accross data-centers
Consistency to be either eventual (with Last-Write-Wins) or just "best effort"

In general, this means avoiding updates during idempotent HTTP requests (GET/HEAD) and avoiding assumptions of true linearizability (e.g. accepting anomalies). Modules that need these kind of guarantees should use other storage mediums.

Valid options are the keys of $wgObjectCaches, e.g. CACHE_* constants.

Since: 1.26

Definition at line 2675 of file DefaultSettings.php.

◆ $wgMainWANCache

$wgMainWANCache = false

Main Wide-Area-Network cache type.

By default, this will wrap $wgMainCacheType (which is disabled, since the basic stock default of CACHE_DB is not fast enough to make it worthwhile).

For single server or single data-center setup, setting $wgMainCacheType is enough.

For a multiple data-center setup, WANObjectCache should be configured to broadcast some if its operations using Mcrouter or Dynomite. See Deploying WANObjectCache.

The options are:

false: Configure the cache using $wgMainCacheType, without using a relayer (only matters if there are multiple data-centers)
CACHE_NONE: Do not cache
(other): A string may be used which identifies a cache configuration in $wgWANObjectCaches

$wgMaxImageArea = 1.25e7

The maximum number of pixels a source image can have if it is to be scaled down by a scaler that requires the full source image to be decompressed and stored in decompressed form, before the thumbnail is generated.

This provides a limit on memory usage for the decompression side of the image scaler. The limit is used when scaling PNGs with any of the built-in image scalers, such as ImageMagick or GD. It is ignored for JPEGs with ImageMagick, and when using the VipsScaler extension.

◆ $wgPasswordPolicy

$wgPasswordPolicy

Password policy for the wiki.

Structured as [ 'policies' => [ <group> => [ <policy> => <settings>, ... ], ... ], 'checks' => [ <policy> => <callback>, ... ], ] where <group> is a user group, <policy> is a password policy name (arbitrary string) defined in the 'checks' part, <callback> is the PHP callable implementing the policy check, <settings> is an array of options with the following keys:

value: (number, boolean or null) the value to pass to the callback
forceChange: (bool, default false) if the password is invalid, do not let the user log in without changing the password
suggestChangeOnLogin: (bool, default false) if true and the password is invalid, suggest a password change if logging in. If all the failing policies that apply to the user have this set to false, the password change screen will not be shown. 'forceChange' takes precedence over 'suggestChangeOnLogin' if they are both present. As a shorthand for [ 'value' =>

], simply

can be written. When multiple password policies are defined for a user, the settings arrays are merged, and for fields which are set in both arrays, the larger value (as understood by PHP's 'max' method) is taken.

A user's effective policy is the superset of all policy statements from the policies for the groups where the user is a member. If more than one group policy include the same policy statement, the value is the max() of the values. Note true > false. The 'default' policy group is required, and serves as the minimum policy for all users.

Callbacks receive three arguments: the policy value, the User object and the password; and must return a StatusValue. A non-good status means the password will not be accepted for new accounts, and existing accounts will be prompted for password change or barred from logging in (depending on whether the status is a fatal or merely error/warning).

The checks supported by core are:

MinimalPasswordLength - Minimum length a user can set.
MinimumPasswordLengthToLogin - Passwords shorter than this will not be allowed to login, or offered a chance to reset their password as part of the login workflow, regardless if it is correct.
MaximalPasswordLength - maximum length password a user is allowed to attempt. Prevents DoS attacks with pbkdf2.
PasswordCannotMatchUsername - Password cannot match the username.
PasswordCannotBeSubstringInUsername - Password cannot be a substring (contained within) the username.
PasswordCannotMatchBlacklist - Username/password combination cannot match a list of default passwords used by MediaWiki in the past. Deprecated since 1.35, use PasswordCannotMatchDefaults instead.
PasswordCannotMatchDefaults - Username/password combination cannot match a list of default passwords used by MediaWiki in the past.
PasswordNotInLargeBlacklist - Password not in best practices list of 100,000 commonly used passwords. Due to the size of the list this is a probabilistic test. Deprecated since 1.35, use PasswordNotInCommonList instead.
PasswordNotInCommonList - Password not in best practices list of 100,000 commonly used passwords. Due to the size of the list this is a probabilistic test.

If you add custom checks, for Special:PasswordPolicies to display them correctly, every check should have a corresponding passwordpolicies-policy-<check> message, and every settings field other than 'value' should have a corresponding passwordpolicies-policyflag-<flag> message (<check> and <flag> are in lowercase). The check message receives the policy value as a parameter, the flag message receives the flag value (or values if it's an array).

'UDPRCFeedEngine' - sends recent changes over UDP to the specified server.
'RedisPubSubFeedEngine' - send recent changes to Redis.

Only 'class' or 'uri' is required. If 'uri' is set instead of 'class', then RecentChange::getEngine() is used to determine the class. All options are passed to the constructor.

Common options:

'class' – The class to use for this feed (must implement RCFeed).
'omit_bots' – Exclude bot edits from the feed. (default: false)
'omit_anon' – Exclude anonymous edits from the feed. (default: false)
'omit_user' – Exclude edits by registered users from the feed. (default: false)
'omit_minor' – Exclude minor edits from the feed. (default: false)
'omit_patrolled' – Exclude patrolled edits from the feed. (default: false)

FormattedRCFeed-specific options:

'uri' – [required] The address to which the messages are sent. The uri scheme of this string will be looked up in $wgRCEngines to determine which FormattedRCFeed class to use.
'formatter' – [required] The class (implementing RCFeedFormatter) which will produce the text to send. This can also be an object of the class. Formatters available by default: JSONRCFeedFormatter, XMLRCFeedFormatter, IRCColourfulRCFeedFormatter.

IRCColourfulRCFeedFormatter-specific options:

'add_interwiki_prefix' – whether the titles should be prefixed with the first entry in the $wgLocalInterwikis array

◆ $wgReauthenticateTime

int [] $wgReauthenticateTime

Initial value:

= [
    'default' => 300,
]

Time frame for re-authentication.

With only password-based authentication, you'd just ask the user to re-enter their password to verify certain operations like changing the password or changing the account's email address. But under AuthManager, the user might not have a password (you might even have to redirect the browser to a third-party service or something complex like that), you might want to have both factors of a two-factor authentication, and so on. So, the options are:

Incorporate the whole multi-step authentication flow within everything that needs to do this.
Consider it good if they used Special:UserLogin during this session within the last X seconds.
Come up with a third option.

MediaWiki currently takes the second option. This setting configures the "X seconds".

This allows for configuring different time frames for different "operations". The operations used in MediaWiki core include:

LinkAccounts
UnlinkAccount
ChangeCredentials
RemoveCredentials
ChangeEmail

Additional operations may be used by extensions, either explicitly by calling AuthManager::securitySensitiveOperationStatus(), ApiAuthManagerHelper::securitySensitiveOperation() or SpecialPage::checkLoginSecurityLevel(), or implicitly by overriding SpecialPage::getLoginSecurityLevel() or by subclassing AuthManagerSpecialPage.

The key 'default' is used if a requested operation isn't defined in the array.

Setting it to an array (supported since 1.31) will create a meta tag for each value, in the reverse of the order (meaning that the first array element will be the default and the others used as fallbacks for browsers which do not understand it).

Following options to distinguish:

versioned: Used for modules with a version, because changing version numbers causes cache misses. This normally has a long expiry time.
unversioned: Used for modules without a version to propagate changes quickly to clients. Also used for modules with errors to recover quickly. This normally has a short expiry time.

◆ $wgResourceModules

$wgResourceModules = []

Define extra client-side modules to be registered with ResourceLoader.

NOTE: It is recommended to define modules in extension.json or skin.json whenever possible.

Using resource modules

By default modules are registered as an instance of ResourceLoaderFileModule. You find the relevant code in resources/Resources.php. These are the options:

class

Alternate subclass of ResourceLoaderModule (rather than default ResourceLoaderFileModule). If this is used, some of the other properties may not apply, and you can specify your own arguments. Since MediaWiki 1.30, it may now specify a callback function as an alternative to a plain class name, using the factory key in the module description array. This allows dependency injection to be used for ResourceLoader modules.

Class name of alternate subclass

Example:: $wgResourceModules['ext.myExtension'] = [

'class' => ResourceLoaderWikiModule::class,

];

$wgResourceModules
$wgResourceModules
Define extra client-side modules to be registered with ResourceLoader.

'deprecated' => 'You should use ext.myExtension2 instead',

];

group

Group which this module should be loaded together with.

Group name string.

Example:: $wgResourceModules['ext.myExtension'] = [

'group' => 'myExtGroup',

];

languageScripts

Boolean.

Example:: $wgResourceModules['ext.myExtension'] = [

'noflip' => true,

];

packageFiles

Package files that can be require()d. 'packageFiles' cannot be combined with any of the scripts options: 'scripts', 'languageScripts' and 'debugScripts'.

];

remoteExtPath

Equivalent of remoteBasePath, but relative to $wgExtensionAssetsPath. Cannot be combined with remoteBasePath

File path string or array of file path strings.

Example:: $wgResourceModules['ext.myExtension'] = [

'languageScripts' => [

'bs' => 'extensions/MyExtension/languages/bs.js',

'fi' => 'extensions/MyExtension/languages/fi.js',

],

'scripts' => [

'extensions/MyExtension/myExtension.js',

'extensions/MyExtension/utils.js',

],

];

skinScripts

Scripts to include in specific skin contexts.

Array keyed by skin name containing file path string or array of file path strings.

skipFunction

Function that returns true when the module should be skipped. Intended for when the module provides a polyfill that is not required in modern browsers

Filename of a JavaScript file with a top-level return (it should not be wrapped in a function).

Example:: $wgResourceModules['ext.myExtension'] = [

'skipFunction' => 'myext-polyfill-needed.js',

];

styles

Styles to always include in the module.

File path string or list of file path strings. The included file can be automatically wrapped in a @media query by specifying the file path as the key in an object, with the value specifying the media query.

See $wgResourceModuleSkinStyles below for additional examples.

Example:: $wgResourceModules['example'] = [

'styles' => [

'foo.css',

'bar.css',

],

];

$wgResourceModules['example.media'] = [

'styles' => [

'foo.css' => [ 'media' => 'print' ],

];

Example:: $wgResourceModules['ext.myExtension'] = [

'templates' => [

'templates/template.html',

'templates/template2.html',

],

];

Definition at line 4012 of file DefaultSettings.php.

◆ $wgResourceModuleSkinStyles

$wgResourceModuleSkinStyles = []

Add extra skin-specific styles to a resource module.

These are automatically added by ResourceLoader to the 'skinStyles' list of the existing module. The 'styles' list cannot be modified or disabled.

For example, below a module "bar" is defined and skin Foo provides additional styles for it:

Example:: $wgResourceModules['bar'] = [

'scripts' => 'resources/bar/bar.js',

'styles' => 'resources/bar/main.css',

];

$wgResourceModuleSkinStyles['foo'] = [

'bar' => 'skins/Foo/bar.css',

];

$wgResourceModuleSkinStyles
$wgResourceModuleSkinStyles
Add extra skin-specific styles to a resource module.
Definition DefaultSettings.php:4103

This is effectively equivalent to:

Equivalent:: $wgResourceModules['bar'] = [

'scripts' => 'resources/bar/bar.js',

'styles' => 'resources/bar/main.css',

'skinStyles' => [

'foo' => skins/Foo/bar.css',

],

];

If the module already defines its own entry in skinStyles for a given skin, then $wgResourceModuleSkinStyles is ignored.

If a module defines a ‘skinStyles['default’]the skin may want to extend that instead of replacing it. This can be done using the+` prefix.

Example:: $wgResourceModules['bar'] = [

'scripts' => 'resources/bar/bar.js',

'styles' => 'resources/bar/basic.css',

'skinStyles' => [

'default' => 'resources/bar/additional.css',

],

];

// Note the '+' character:

$wgResourceModuleSkinStyles['foo'] = [

'+bar' => 'skins/Foo/bar.css',

];

This is effectively equivalent to:

Equivalent:: $wgResourceModules['bar'] = [

'scripts' => 'resources/bar/bar.js',

'styles' => 'resources/bar/basic.css',

'skinStyles' => [

'default' => 'resources/bar/additional.css',

'foo' => [

'resources/bar/additional.css',

'skins/Foo/bar.css',

],

],

];

In other words, as a module author, use the styles list for stylesheets that may not be disabled by a skin. To provide default styles that may be extended or replaced, use ‘skinStyles['default’]`.

As with $wgResourceModules, always set the localBasePath and remoteBasePath keys (or one of remoteExtPath/remoteSkinPath).

Example:: $wgResourceModuleSkinStyles['foo'] = [

'bar' => 'bar.css',

'quux' => 'quux.css',

'remoteSkinPath' => 'Foo',

'localBasePath' => __DIR__,

];

Certain places in the interface recognize a dichotomy between "protected" and "semiprotected", without further distinguishing the specific levels. In general, if anyone can be eligible to edit a protection level merely by reaching some condition in $wgAutopromote, it should probably be considered "semiprotected".

◆ $wgSharedDB

$wgSharedDB = null

Shared database for multiple wikis.

Commonly used for storing a user table for single sign-on. The server for this database must be the same as for the main database.

For backwards compatibility the shared prefix is set to the same as the local prefix, and the user table is listed in the default list of shared tables. The user_properties table is also added so that users will continue to have their preferences shared (preferences were stored in the user table prior to 1.16)

$wgSharedTables may be customized with a list of tables to share in the shared database. However it is advised to limit what tables you do share as many of MediaWiki's tables may have side effects if you try to share them.

$wgSharedPrefix is the table prefix for the shared database. It defaults to $wgDBprefix.

$wgSharedSchema is the table schema for the shared database. It defaults to $wgDBmwschema.

Deprecated:: since 1.21 In new code, use the $wiki parameter to LBFactory::getMainLB() to access remote databases. Using LBFactory::getMainLB() allows the shared database to reside on separate servers to the wiki's own database, with suitable configuration of $wgLBFactoryConf.

◆ $wgShellCgroup

$wgShellCgroup = false

Under Linux: a cgroup directory used to constrain memory usage of shell commands.

The directory must be writable by the user which runs MediaWiki.

If specified, this is used instead of ulimit, which is inaccurate, and causes malloc() to return NULL, which exposes bugs in C applications, making them segfault or deadlock.

A wrapper script will create a cgroup for each shell command that runs, as a subgroup of the specified cgroup. If the memory limit is exceeded, the kernel will send a SIGKILL signal to a process in the subgroup.

Example:: mkdir -p /sys/fs/cgroup/memory/mediawiki

mkdir -m 0777 /sys/fs/cgroup/memory/mediawiki/job

echo '$wgShellCgroup = "/sys/fs/cgroup/memory/mediawiki/job";' >> LocalSettings.php

The reliability of cgroup cleanup can be improved by installing a notify_on_release script in the root cgroup, see e.g. https://gerrit.wikimedia.org/r/#/c/40784

Definition at line 8841 of file DefaultSettings.php.

◆ $wgShellLocale

$wgShellLocale = 'C.UTF-8'

Locale for LC_ALL, to provide a known environment for locale-sensitive operations.

For Unix-like operating systems, this should be set to C.UTF-8 or an equivalent to provide the most consistent behavior for locale-sensitive C library operations across different-language wikis. If that locale is not available, use another locale that has a UTF-8 character set.

This setting mainly affects the behavior of C library functions, including:

String collation (order when sorting using locale-sensitive comparison)
- For example, whether "Å" and "A" are considered to be the same letter or different letters and if different whether it comes after "A" or after "Z", and whether sorting is case sensitive.
String character set (how characters beyond basic ASCII are represented)
- We need this to be a UTF-8 character set to work around https://bugs.php.net/bug.php?id=45132
Language used for low-level error messages.
Formatting of date/time and numeric values (e.g. '.' versus ',' as the decimal separator)

MediaWiki provides its own methods and classes to perform many locale-sensitive operations, which are designed to be able to vary locale based on wiki language or user preference:

MediaWiki's Collation class should generally be used instead of the C library collation functions when locale-sensitive sorting is needed.
MediaWiki's Message class should be used for localization of messages displayed to the user.
MediaWiki's Language class should be used for formatting numeric and date/time values.

Note: If multiple wikis are being served from the same process (e.g. the same fastCGI or Apache server), this setting must be the same on all those wikis.

◆ $wgShellRestrictionMethod

◆ $wgThumbnailBuckets

$wgThumbnailBuckets = null

The goal is to save resources by generating thumbnails based on reference buckets instead of always using the original. This will incur a speed gain but cause a quality loss.

◆ $wgThumbnailMinimumBucketDistance

$wgThumbnailMinimumBucketDistance = 50

When using thumbnail buckets as defined above, this sets the minimum distance to the bucket above the requested size.

The distance represents how many extra pixels of width the bucket needs in order to be used as the reference for a given thumbnail. For example, with the following buckets:

$wgThumbnailBuckets = [ 128, 256, 512 ];

and a distance of 50:

$wgThumbnailMinimumBucketDistance = 50;

If we want to render a thumbnail of width 220px, the 512px bucket will be used, because 220 + 50 = 270 and the closest bucket bigger than 270px is 512.

To find the temporary path for the current wiki, developers must not use this variable directly. Use the global function wfTempDir() instead.

The temporary directory is expected to be shared with other applications, including other MediaWiki instances (which might not run the same version or configution). When storing files here, take care to avoid conflicts with other instances of MediaWiki. For example, when caching the result of a computation, the file name should incorporate the input of the computation so that it cannot be confused for the result of a similar computation by another MediaWiki instance.

◆ $wgUserEmailUseReplyTo

$wgUserEmailUseReplyTo = true

If true put the sending user's email in a Reply-To header instead of From (false).

($wgPasswordSender will be used as From.)

Some mailers (eg SMTP) set the SMTP envelope sender to the From value, which can cause problems with SPF validation and leak recipient addresses when bounces are sent to the sender. In addition, DMARC restrictions can cause emails to fail to be received when false.

◆ $wgUserrightsInterwikiDelimiter

$wgUserrightsInterwikiDelimiter = '@'

Character used as a delimiter when testing for interwiki userrights (In Special:UserRights, it is possible to modify users on different databases if the delimiter is used, e.g.

"Someuser@enwiki").

It is recommended that you have this delimiter in $wgInvalidUsernameCharacters above, or you will not be able to modify the user rights of those users via Special:UserRights

Definition at line 7082 of file DefaultSettings.php.

◆ $wgValidSkinNames

$wgValidSkinNames = []

List of valid skin names.

The key should be the name in all lower case.

As of 1.35, the value should be a an array in the form of the ObjectFactory specification.

For example for 'foobarskin' where the PHP class is 'MediaWiki\Skins\FooBar\FooBarSkin' set:

skin.json Example:: "ValidSkinNames": {

"foobarskin": {

"displayname": "FooBarSkin",

"class": "MediaWiki\\\\Skins\\\\FooBar\\\\FooBarSkin"

}

}

Historically, the value was a properly cased name for the skin (and is still currently supported). This value will be prefixed with "Skin" to create the class name of the skin to load. Use Skin::getSkinNames() as an accessor if you wish to have access to the full list.

◆ $wgVirtualRestConfig

array $wgVirtualRestConfig

Initial value:

= [
    'paths' => [],
    'modules' => [],
    'global' => [
        # Timeout in seconds
        'timeout' => 360,
        # 'domain' is set to $wgCanonicalServer in Setup.php
        'forwardCookies' => false,
        'HTTPProxy' => null
    ]
]

Global configuration variable for Virtual REST Services.

Use the 'path' key to define automatically mounted services. The value for this key is a map of path prefixes to service configuration. The latter is an array of:

class : the fully qualified class name
options : map of arguments to the class constructor Such services will be available to handle queries under their path from the VRS singleton, e.g. MediaWikiServices::getInstance()->getVirtualRESTServiceClient();

Auto-mounting example for Parsoid:

$wgVirtualRestConfig['paths']['/parsoid/'] = [ 'class' => ParsoidVirtualRESTService::class, 'options' => [ 'url' => 'http://localhost:8000', 'prefix' => 'enwiki', 'domain' => 'en.wikipedia.org' ] ];

Parameters for different services can also be declared inside the 'modules' value, which is to be treated as an associative array. The parameters in 'global' will be merged with service-specific ones. The result will then be passed to VirtualRESTService::__construct() in the module.

Example config for Parsoid:

$wgVirtualRestConfig['modules']['parsoid'] = [ 'url' => 'http://localhost:8000', 'prefix' => 'enwiki', 'domain' => 'en.wikipedia.org', ];

◆ $wgVueDevelopmentMode

$wgVueDevelopmentMode = false

◆ $wgWANObjectCaches

$wgWANObjectCaches

Initial value:

= [
    CACHE_NONE => [
        'class' => WANObjectCache::class,
        'cacheId' => CACHE_NONE,
    ]
]

Advanced WAN object cache configuration.

The format is an associative array where the key is an identifier that may be referenced by $wgMainWANCache, and the value is an array of options:

class: (Required) The class to use (must be WANObjectCache or a subclass).
cacheId: (Required) A cache identifier from $wgObjectCaches.
secret: (Optional) Stable secret for hashing long strings in key components. Default: $wgSecretKey.

Any other options are treated as constructor parameters to WANObjectCache, except for 'cache', 'logger', 'stats' and 'asyncHandler' which are unconditionally set by MediaWiki core's ServiceWiring.

Example:: $wgWANObjectCaches'memcached-php' => [

'class' => WANObjectCache::class,

'cacheId' => 'memcached-php',

];

Definition DefaultSettings.php:5511

Special:Userlogin and Special:ChangePassword are always allowed.

Note: This will only work if $wgGroupPermissions['*']['read'] is false – see below. Otherwise, ALL pages are accessible, regardless of this setting.; Also that this will only protect pages in the wiki. Uploaded files will remain readable. You can use img_auth.php to protect uploaded files, see https://www.mediawiki.org/wiki/Manual:Image_Authorization; Extensions should not modify this, but use the TitleReadWhitelist hook instead.

Definition at line 5511 of file DefaultSettings.php.

◆ $wgWhitelistReadRegexp

$wgWhitelistReadRegexp = false

Definition DefaultSettings.php:5539

Note: Unless ^ and/or $ is specified, a regular expression might match pages not intended to be allowed. The above example will also allow a page named 'Security Main Page'.

Example:: To allow reading any page starting with 'User' regardless of the case:
$wgWhitelistReadRegexp = [ "@^UsEr.*@i" ];

Will allow both [[User is banned]] and [[User:JohnDoe]]
