Detailed Description

Default values for MediaWiki configuration settings.

            NEVER EDIT THIS FILE

To customize your installation, edit "LocalSettings.php". If you make changes here, they will be lost on next upgrade of MediaWiki!

In this file, variables whose default values depend on other variables are set to false. The actual default value of these variables will only be set in Setup.php, taking into account any custom settings performed in LocalSettings.php.

$wgActionPaths = []

To set 'pretty' URL paths for actions other than plain page views, add to this array.

Example:

Set pretty URL for the edit action:

'edit' => "$wgScriptPath/edit/$1"

There must be an appropriate script or rewrite rule in place to handle these URLs.

$wgActiveUserDays

$wgActiveUserDays = 30

How many days user must be idle before he is considered inactive.

Will affect the number shown on Special:Statistics, Special:ActiveUsers, and the {{NUMBEROFACTIVEUSERS}} magic word in wikitext. You might want to leave this as the default value, to provide comparable numbers between different wikis.

$wgAdaptiveMessageCache

$wgAdaptiveMessageCache = false

Instead of caching everything, only cache those messages which have been customised in the site content language.

This means that MediaWiki:Foo/ja is ignored if MediaWiki:Foo doesn't exist. This option is probably only useful for translatewiki.net.

$wgAddGroups

$wgAddGroups = []

$wgAddGroups and $wgRemoveGroups can be used to give finer control over who can assign which groups at Special:Userrights.

Example:

Bureaucrats can add any group:

$wgAddGroups['bureaucrat'] = true;

Bureaucrats can only remove bots and sysops:

$wgRemoveGroups['bureaucrat'] = [ 'bot', 'sysop' ];

Sysops can make bots:

$wgAddGroups['sysop'] = [ 'bot' ];

Sysops can disable other sysops in an emergency, and disable bots:

$wgRemoveGroups['sysop'] = [ 'sysop', 'bot' ];

$wgAllowCopyUploads

$wgAllowCopyUploads = false

Allow for upload to be copied from an URL.

The timeout for copy uploads is set by $wgCopyUploadTimeout. You have to assign the user right 'upload_by_url' to a user group, to use this.

$wgAllowExternalImagesFrom

$wgAllowExternalImagesFrom = ''

If the above is false, you can specify an exception here.

Image URLs that start with this string are then rendered, while all others are not. You can use this to set up a trusted, simple repository of images. You may also specify an array of strings to allow multiple sites

Examples:

Allows to move images and other media files.

Definition at line 439 of file DefaultSettings.php.

$wgAllowImageTag

$wgAllowImageTag = false

A different approach to the above: simply allow the "<img>" tag to be used.

This allows you to specify alt text and other attributes, copy-paste HTML to your wiki more easily, etc. However, allowing external images in any manner will allow anyone with editing rights to snoop on your visitors' IP addresses and so forth, if they wanted to, by inserting links to images on sites they control.

Definition at line 4525 of file DefaultSettings.php.

$wgAllowJavaUploads

$wgAllowJavaUploads = false

$wgAllowSecuritySensitiveOperationIfCannotReauthenticate

bool [] $wgAllowSecuritySensitiveOperationIfCannotReauthenticate

Initial value:

= [
    'default' => true,
]

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.

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

$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.

Since

1.25

$wgAntivirus

$wgAntivirus = null

Internal name of virus scanner.

This serves as a key to the $wgAntivirusSetup array. Set this to NULL to disable virus scanning. If not null, every file uploaded will be scanned for viruses.

Definition at line 1369 of file DefaultSettings.php.

$wgAntivirusRequired

$wgAntivirusRequired = true

Determines if a failed virus scan (AV_SCAN_FAILED) will cause the file to be rejected.

Definition at line 1423 of file DefaultSettings.php.

$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.

$wgAPICacheHelpTimeout

$wgAPICacheHelpTimeout = 60 * 60

Set the timeout for the API help text cache.

If set to 0, caching disabled

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

See ApiMain::$Formats for a list of the core format modules.

Definition at line 8403 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 3439 of file DefaultSettings.php.

$wgAPIListModules

This should be lower than the 'max lag' value in $wgLBFactoryConf.

Definition at line 8455 of file DefaultSettings.php.

$wgAPIMaxResultSize

$wgAPIMaxResultSize = 8388608

The maximum size (in bytes) of an API result.

Warning

Definition at line 8442 of file DefaultSettings.php.

$wgAPIMaxUncachedDiffs

$wgAPIMaxUncachedDiffs = 1

The maximum number of uncached diffs that can be retrieved in one API request.

Set this to 0 to disable API diffs altogether

Definition at line 8448 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 8412 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 8394 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.

See ApiQuery::$QueryPropModules for a list of the core prop modules.

Definition at line 8421 of file DefaultSettings.php.

$wgAPIRequestLog

$wgAPIRequestLog = false

Log file or URL (TCP or UDP) to log API requests to, or false to disable API request logging.

$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.

Initial value:

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

]

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.

• 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

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.

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' => [

    ]
]

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.

$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.

$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.

$wgFileBackends

$wgFileBackends = []

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.

            "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.

$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' ];

Definition at line 3221 of file DefaultSettings.php.

$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 705 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.

$wgGalleryOptions

• 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;

array $wgGrantPermissions = []

Map of (grant => right => boolean) Users authorize consumers (like Apps) to act on their behalf but only with a subset of the user's normal account rights (signed off on by the user).

The possible rights to grant to a consumer are bundled into groups called "grants". Each grant defines some rights it lets consumers inherit from the account they may act on behalf of. Note that a user granting a right does nothing if that user does not actually have that right to begin with.

$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!

The value can be one of:

• A function name:

  $wgHooks['event_name'][] = $function;

• A function with some data:

  $wgHooks['event_name'][] = [ $function, $data ];

• A an object method:

Warning

You should always append to an event array or you will end up deleting a previous registered hook.

Hook handlers should be registered at file scope. Registering handlers after file scope can lead to unexpected results due to caching.

$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 = [

$wgJpegQuality = 80

When scaling a JPEG thumbnail, this is the quality we request from the backend.

It should be an int between 1 and 100, with 100 indicating 100% quality.

$wgLangObjCacheSize

$wgLangObjCacheSize = 10

Language cache size, or really how many languages can we handle simultaneously without degrading to crawl speed.

Definition at line 3004 of file DefaultSettings.php.

$wgLanguageCode

$wgLanguageCode = 'en'

Site language code.

See languages/data/Names.php for languages supported by MediaWiki out of the box. Not all languages listed there have translations, see languages/messages/ for the list of languages with some localisation.

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.

This also defines the language of pages in the wiki. The content is wrapped in a html element with lang=XX attribute. This behavior can be overridden via hooks, see Title::getPageLanguage.

$wgLBFactoryConf

$wgLBFactoryConf = [ 'class' => \Wikimedia\Rdbms\LBFactorySimple::class ]

Load balancer factory configuration To set up a multi-master wiki farm, set the class here to something that can return a LoadBalancer with an appropriate master on a call to getMainLB().

The class identified here is responsible for reading $wgDBservers, $wgDBserver, etc., so overriding it may cause those globals to be ignored.

The LBFactoryMulti class is provided for this purpose, please see includes/db/LBFactoryMulti.php for configuration information.

$wgLearnerEdits

$wgLearnerEdits = 10

The following variables define 3 user experience levels:

• newcomer: has not yet reached the 'learner' level
• learner: has at least $wgLearnerEdits and has been a member for $wgLearnerMemberSince days but has not yet reached the 'experienced' level.
• experienced: has at least $wgExperiencedUserEdits edits and has been a member for $wgExperiencedUserMemberSince days.

$wgLearnerMemberSince

$wgLearnerMemberSince = 4

Specify the difference engine to use.

Supported values:

• 'external': Use an external diff engine, which must be specified via $wgExternalDiffEngine
• 'wikidiff2': Use the wikidiff2 PHP extension
• 'php': PHP implementations included in MediaWiki

The default (null) is to use the first engine that's available.

$wgLegacyEncoding

$wgLegacyEncoding = false

Set this to eg 'ISO-8859-1' to perform character set conversion when loading old revisions not marked with "utf-8" flag.

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.

Definition at line 3105 of file DefaultSettings.php.

$wgLegacyJavaScriptGlobals

$wgLegacyJavaScriptGlobals = true

Whether or not to assign configuration variables to the global window object.

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

Example of legacy code:

if ( window.wgRestrictionEdit ) { ... }

or:

if ( wgIsArticle ) { ... }

Instead, one needs to use mw.config.

Example using mw.config global configuration:

if ( mw.config.exists('wgRestrictionEdit') ) { ... }

or:

if ( mw.config.get('wgIsArticle') ) { ... }

Definition at line 4060 of file DefaultSettings.php.

$wgLegacySchemaConversion

$wgLegacySchemaConversion = false

If set to true, the MediaWiki 1.4 to 1.5 schema conversion will create stub reference rows in the text table instead of copying the full text of all current entries from 'cur' to 'text'.

This will speed up the conversion step for large sites, but requires that the cur table be kept around for those revisions to remain viewable.

This option affects the updaters only. Any present cur stub revisions will be readable at runtime regardless of this setting.

$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.
