URLs and file paths

These various web and file path variables are set to their defaults in Setup.php if they are not explicitly set from LocalSettings.php.

In this section, a "path" is usually a host-relative URL, i.e. a URL without the host part, that starts with a slash. In most cases a full URL is also acceptable. A "directory" is a local file path.

◆ $wgActions

$wgActions
Initial value:
= [
'credits' => true,

'revisiondelete' => 'SpecialPageAction',
'rollback' => true,
'submit' => true,
'unprotect' => true,
'unwatch' => true,

◆ $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:

$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' ];

◆ $wgAllowImageMoving

$wgAllowImageMoving = true

Allows to move images and other media files.

Definition at line 388 of file DefaultSettings.php.

Referenced by MWNamespace\isMovable().

◆ $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 4278 of file DefaultSettings.php.

◆ $wgAllowJavaUploads

$wgAllowJavaUploads = false

Allow Java archive uploads.

This is not recommended for public wikis since a maliciously-constructed applet running on the same domain as the wiki can steal the user's cookies.

Definition at line 2191 of file DefaultSettings.php.

Referenced by UpdateMediaWiki\execute().

◆ $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.

Since
1.27
See also
$wgReauthenticateTime operation => boolean. A 'default' key must always be provided.

Definition at line 4694 of file DefaultSettings.php.

◆ $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

Definition at line 3843 of file DefaultSettings.php.

◆ $wgAllowSpecialInclusion

$wgAllowSpecialInclusion = true

Allow special page inclusions such as {{Special:Allpages}}.

Definition at line 7806 of file DefaultSettings.php.

Referenced by ParserOptions\getDefaults().

◆ $wgAllowTitlesInSVG

$wgAllowTitlesInSVG = false

Disallow <title> element in SVG files.

MediaWiki will reject HTMLesque tags in uploaded files due to idiotic browsers which can not perform basic stuff like MIME detection and which are vulnerable to further idiots uploading crap files as images.

When this directive is on, "<title>" will be allowed in files with an "image/svg+xml" MIME type. You should leave this disabled if your web server is misconfigured and doesn't send appropriate MIME types for SVG images.

Definition at line 1153 of file DefaultSettings.php.

◆ $wgAllowUserCss

$wgAllowUserCss = false

Allow user Cascading Style Sheets (CSS)? This enables a lot of neat customizations, but may increase security risk to users and server load.

Definition at line 3292 of file DefaultSettings.php.

◆ $wgAllowUserCssPrefs

$wgAllowUserCssPrefs = true

Allow user-preferences implemented in CSS? This allows users to customise the site appearance to a greater degree; disabling it will improve page load times.

Definition at line 3299 of file DefaultSettings.php.

◆ $wgAllowUserJs

$wgAllowUserJs = false

Allow user Javascript page? This enables a lot of neat customizations, but may increase security risk to users and server load.

Definition at line 3285 of file DefaultSettings.php.

◆ $wgAllUnicodeFixes

$wgAllUnicodeFixes = false

Set this to always convert certain Unicode sequences to modern ones regardless of the content language.

This has a small performance impact.

◆ $wgAmericanDates

$wgAmericanDates = false

Enable dates like 'May 12' instead of '12 May', if the default date format is 'dmy or mdy'.

Definition at line 3005 of file DefaultSettings.php.

◆ $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 1248 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 1302 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.

Definition at line 1284 of file DefaultSettings.php.

◆ $wgAPICacheHelpTimeout

$wgAPICacheHelpTimeout = 60 * 60

Set the timeout for the API help text cache.

If set to 0, caching disabled

Definition at line 8085 of file DefaultSettings.php.

◆ $wgAPIFormatModules

$wgAPIFormatModules = []

API format module extensions.

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 8022 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 3348 of file DefaultSettings.php.

◆ $wgAPIListModules

$wgAPIListModules = []

API Query list module extensions.

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

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

Definition at line 8049 of file DefaultSettings.php.

◆ $wgAPIMaxDBRows

$wgAPIMaxDBRows = 5000

Maximum amount of rows to scan in a DB query in the API The default value is generally fine.

Definition at line 8055 of file DefaultSettings.php.

◆ $wgAPIMaxLagThreshold

$wgAPIMaxLagThreshold = 7

Maximum amount of DB lag on a majority of DB replica DBs to tolerate before forcing bots to retry any write requests via API errors.

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

Definition at line 8074 of file DefaultSettings.php.

◆ $wgAPIMaxResultSize

$wgAPIMaxResultSize = 8388608

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

Warning
Do not set this lower than $wgMaxArticleSize*1024

Definition at line 8061 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 8067 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 8031 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',
'factory' => function( $main, $name ) { ... }
];
$wgAPIModules['xyzzy'] = [
'class' => 'ApiXyzzy',
'factory' => [ 'XyzzyFactory', 'newApiModule' ]
];

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

Definition at line 8013 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 8040 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.

Definition at line 8080 of file DefaultSettings.php.

◆ $wgAPIUselessQueryPages

$wgAPIUselessQueryPages
Initial value:
= [
'MIMEsearch',
'LinkSearch',
'FileDuplicateSearch',
]

The ApiQueryQueryPages module should skip pages that are redundant to true API queries.

Definition at line 8091 of file DefaultSettings.php.

◆ $wgAutoloadClasses

◆ $wgAutopromote

$wgAutopromote
Initial value:
= [
'autoconfirmed' => [ '&',
],
]

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

The basic syntax for $wgAutopromote is:

$wgAutopromote = array(
    '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 array( APCOND_EMAILCONFIRMED )
  • a single condition with arguments: e.g. array( APCOND_EDITCOUNT, 100 )
  • a set of conditions: e.g. ‘array( '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
  • array( APCOND_EMAILCONFIRMED ): true if user has a confirmed e-mail
  • array( APCOND_EDITCOUNT, number of edits ): true if user has the at least the number of edits as the passed parameter
  • array( 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
  • array( 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
  • array( APCOND_INGROUPS, group1, group2, ... ): true if the user is a member of each of the passed groups
  • array( APCOND_ISIP, ip ): true if the user has the passed IP address
  • array( APCOND_IPINRANGE, range ): true if the user has an IP address in the range of the passed parameter
  • array( APCOND_BLOCKED ): true if the user is blocked
  • array( 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.

$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.

  • 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://secure.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.

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 puge will clear cdn2 after cdn1 was cleared.

◆ $wgDBOracleDRCP

$wgDBOracleDRCP = false

Set true to enable Oracle DCRP (supported from 11gR1 onward)

To use this feature set to true and use a datasource defined as POOLED (i.e. in tnsnames definition set server=pooled in connect_data block).

Starting from 11gR1 you can use DCRP (Database Resident Connection Pool) that maintains established sessions and reuses them on new connections.

Not completely tested, but it should fall back on normal connection in case the pool is full or the datasource is not configured as pooled. And the other way around; using oci_pconnect on a non pooled datasource should produce a normal connection.

When it comes to frequent shortlived DB connections like with MW Oracle tends to s***. The problem is the driver connects to the database reasonably fast, but establishing a session takes time and resources. MW does not rely on session state (as it does not use features such as package variables) so establishing a valid session is in this case an unwanted overhead that just slows things down.

◆ $wgDBservers

$wgDBservers = false

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
  • 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: 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: bit field
    • DBO_DEFAULT – turns on DBO_TRX only if "cliMode" is off (recommended)
    • DBO_DEBUG – equivalent of $wgDebugDumpSql
    • DBO_TRX – wrap entire request in a transaction
    • DBO_NOBUFFER – turn off buffering (not useful in LocalSettings.php)
    • DBO_PERSISTENT – enables persistent database connections
    • DBO_SSL – uses SSL/TLS encryption in database connections, if available
    • DBO_COMPRESS – uses internal compression in database connections, if available
  • 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. [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',
]
]

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 perfom 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.

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 ...]".

◆ $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)

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 'wikiId' 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.

◆ $wgFilterLogTypes

$wgFilterLogTypes
Initial value:
= [
'patrol' => true,
'tag' => true,

Show/hide links on Special:Log will be shown for these log types.

This is associative array of log type => boolean "hide by default"

See $wgLogTypes for a list of available log types.

Example:
$wgFilterLogTypes = [ 'move' => true, 'import' => false ];

Will display show/hide links for the move and import logs. Move logs will be hidden by default unless the link is clicked. Import logs will be shown by default, and hidden when the link is clicked.

A message of the form log-show-hide-[type] should be added, and will be used for the link text.

◆ $wgFixArabicUnicode

$wgFixArabicUnicode = true

Set this to true to replace Arabic presentation forms with their standard forms in the U+0600-U+06FF block.

◆ $wgFooterIcons

$wgFooterIcons
Initial value:
= [
"copyright" => [
"copyright" => [],
],
"poweredby" => [
"mediawiki" => [
"src" => null,
"url" => "//www.mediawiki.org/",
"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.

◆ $wgForcedRawSMaxage

Definition at line 2733 of file DefaultSettings.php.

◆ $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 3106 of file DefaultSettings.php.

◆ $wgForeignFileRepos

$wgForeignFileRepos = []

◆ $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 540 of file DefaultSettings.php.

◆ $wgFragmentMode

$wgFragmentMode = [ 'legacy' ]

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
  • 'html5-legacy' corresponds to DEPRECATED $wgExperimentalHtmlIds mode. DO NOT use it for anything but migration off that mode (see below).

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

$wgGalleryOptions = []

Parameters for the "<gallery>" tag.

Fields are:

  • 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.

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!

◆ $wgGroupsAddToSelf

$wgGroupsAddToSelf = []

A map of group names that the user is in, to group names that those users are allowed to add or revoke.

Setting the list of groups to add or revoke to true is equivalent to "any group".

Example:
To allow sysops to add themselves to the "bot" group:
$wgGroupsAddToSelf = [ 'sysop' => [ 'bot' ] ];
Example:
Implicit groups may be used for the source group, for instance: This allows users in the '*' group (i.e. any user) to remove themselves from any group that they happen to be in.

Definition at line 847 of file DefaultSettings.php.

◆ $wgHashedUploadDirectory

$wgHashedUploadDirectory = true

Set this to false if you do not want MediaWiki to divide your images directory into many subdirectories, for improved performance.

It's almost always good 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 simply copying them into $wgUploadDirectory and then running maintenance/rebuildImages.php to register them in the database. This is no longer recommended, use maintenance/importImages.php instead.

Note

◆ $wgHooks

$wgHooks = []

Global list of hooks.

The key is one of the events made available by MediaWiki, you can find a description for most of them in docs/hooks.txt. The array is used internally by Hook:run().

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:

  • A closure:
    $wgHooks['event_name'][] = function ( $hookParam ) {
    // Handler code goes here.
    };
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:
'|^https?://upload\\.wikimedia\\.org|' => [
'host' => '239.128.0.113',
'port' => 4827,
],
'' => [
'host' => '239.128.0.112',
'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:
'' => [
// Purges to text caches using multicast
[ 'host' => '239.128.0.114', 'port' => '4827' ],
// Purges to a hardcoded list of caches
[ 'host' => '10.88.66.1', 'port' => '4827' ],
[ 'host' => '10.88.66.2', 'port' => '4827' ],
[ 'host' => '10.88.66.3', 'port' => '4827' ],
],
];
Since

$wgHTCPRouting replaces $wgHTCPMulticastRouting that was introduced in 1.20. For back compatibility purposes, whenever its array is empty $wgHTCPMutlicastRouting will be used as a fallback if it not null.

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' ],

◆ $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.

Theoretically 0x80-0x9F of ISO 8859-1 should be disallowed, but this breaks interlanguage 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
  • 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
  • scriptExtension Script extension of the MediaWiki installation, equivalent to $wgScriptExtension, e.g. ".php5". Defaults to ".php".
  • articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
  • fetchDescription Fetch the text of the remote file description page. Equivalent to $wgFetchCommonsDescriptions.
  • 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 True if the wiki's shared cache is accessible via the local $wgMemc

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.

Associative array with keys: class: The class to use. May be overridden by extensions.

store: The location to store cache data. May be 'files', 'array', 'db' or 'detect'. If set to "files", data will be in CDB files. If set to "db", data will be stored to the database.

◆ $wgMessagesDirs

$wgMessagesDirs = []

Extension messages directories.

Associative array mapping extension name to the path of the directory where message files can be found.

Message directories in core should be added to LocalisationCache::getMessagesDirs()

Simple example:
$wgMessagesDirs['Example'] = __DIR__ . '/i18n';
Complex example:
$wgMessagesDirs['Example'] = [

◆ $wgParserConf

$wgParserConf
Initial value:
= [
'class' => 'Parser',
# 'preprocessorClass' => 'Preprocessor_Hash',

Parser configuration.

Associative array with the following members:

class The class name

preprocessorClass The preprocessor class. Two classes are currently available: Preprocessor_Hash, which uses plain PHP arrays for temporary storage, and Preprocessor_DOM, which uses the DOM module for temporary storage. Preprocessor_DOM generally uses less memory; the speed of the two is roughly the same.

If this parameter is not given, it uses Preprocessor_DOM if the DOM module is available, otherwise it uses Preprocessor_Hash.

The entire associative array will be passed through to the constructor as the first parameter. Note that only Setup.php can use this variable – the configuration will change at runtime via $wgParser member functions, so the contents of this variable will be out-of-date. The variable can only be changed during LocalSettings.php, in particular, it can't be changed during an extension setup function.

The 'default' policy group is required, and serves as the minimum policy for all users. New statements can be added by appending to $wgPasswordPolicy['checks']. Statements:

  • MinimalPasswordLength - minimum length a user can set
  • MinimumPasswordLengthToLogin - passwords shorter than this will not be allowed to login, regardless if it is correct.
  • MaximalPasswordLength - maximum length password a user is allowed to attempt. Prevents DoS attacks with pbkdf2.

◆ $wgRateLimits

$wgRateLimits

Simple rate limiter options to brake edit floods.

Maximum number actions allowed in the given number of seconds; after that the violating client receives HTTP 500 error pages until the period elapses.

Example:
Limits per configured per action and then type of users.
'edit' => [
'anon' => [ x, y ], // any and all anonymous edits (aggregate)
'user' => [ x, y ], // each logged-in user
'newbie' => [ x, y ], // each new autoconfirmed accounts; overrides 'user'
'ip' => [ x, y ], // each anon and recent account
'subnet' => [ x, y ], // ... within a /24 subnet in IPv4 or /64 in IPv6
'groupName' => [ x, y ], // by group membership
]
];
Normally, the 'noratelimit' right allows a user to bypass any rate
limit checks. This can be disabled on a per-action basis by setting the special '&can-bypass' key to false in that action's configuration.
'some-action' => [
'&can-bypass' => false,

◆ $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.

◆ $wgResourceLoaderLESSImportPaths

$wgResourceLoaderLESSImportPaths
Initial value:
= [
"$IP/resources/src/mediawiki.less/",
]

Default import paths for LESS modules.

LESS files referenced in @import statements will be looked up here first, and relative to the importing file second. To avoid collisions, it's important for the LESS files in these directories to have a common, predictable file name prefix.

Extensions need not (and should not) register paths in $wgResourceLoaderLESSImportPaths. The import path includes the path of the currently compiling LESS file, which allows each extension to freely import files from its own tree.

◆ $wgResourceLoaderLESSVars

$wgResourceLoaderLESSVars
Initial value:

'deviceWidthTablet' => '720px',
]

Global LESS variables.

An associative array binding variable names to LESS code snippets representing their values.

Adding an item here is equivalent to writing @variable: value; at the beginning of all your .less files, with all the consequences. In particular, string values must be escaped and quoted.

Changes to this configuration do NOT trigger cache invalidation.

Example:
'exampleFontSize' => '1em',
'exampleBlue' => '#eee',

1.22
Deprecated:
since 1.30 Use ResourceLoaderModule::getLessVars() instead to add variables to individual modules that need them.

],
'unversioned' => [
'server' => 5 * 60,
'client' => 5 * 60,
],
]

Maximum time in seconds to cache resources served by ResourceLoader.

Used to set last modified headers (max-age/s-maxage).

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.

Expiry time for the options to distinguish:

  • server: Squid/Varnish but also any other public proxy cache between the client and MediaWiki.
  • client: On the client side (e.g. in the browser cache).

Definition at line 3657 of file DefaultSettings.php.

◆ $wgResourceLoaderMaxQueryLength

$wgResourceLoaderMaxQueryLength = false

If set to a positive number, ResourceLoader will not generate URLs whose query string is more than this many characters long, and will instead use multiple requests with shorter query strings.

This degrades performance, but may be needed if your web server has a low (less than, say 1024) query string length limit or a low value for suhosin.get.max_value_length that you can't increase.

If set to a negative number, ResourceLoader will assume there is no query string length limit.

Defaults to a value based on php configuration.

Definition at line 3749 of file DefaultSettings.php.

◆ $wgResourceLoaderMinifierMaxLineLength

$wgResourceLoaderMinifierMaxLineLength = 1000

Maximum line length when minifying JavaScript.

This is not a hard maximum: the minifier will try not to produce lines longer than this, but may be forced to do so in certain cases.

Deprecated:
since 1.27: Always 1,000; no longer configurable.

Definition at line 3830 of file DefaultSettings.php.

◆ $wgResourceLoaderValidateJS

$wgResourceLoaderValidateJS = true

If set to true, JavaScript modules loaded from wiki pages will be parsed prior to minification to validate it.

Parse errors will result in a JS exception being thrown during module load, which avoids breaking other modules loaded in the same request.

Definition at line 3758 of file DefaultSettings.php.

◆ $wgResourceLoaderValidateStaticJS

$wgResourceLoaderValidateStaticJS = false

If set to true, statically-sourced (file-backed) JavaScript resources will be parsed for validity before being bundled up into ResourceLoader modules.

This can be helpful for development by providing better error messages in default (non-debug) mode, but JavaScript parsing is slow and memory hungry and may fail on large pre-bundled frameworks.

Definition at line 3768 of file DefaultSettings.php.

◆ $wgResourceModules

$wgResourceModules = []

Client-side resource modules.

Extensions should add their ResourceLoader module definitions to the $wgResourceModules variable.

Example:
$wgResourceModules['ext.myExtension'] = [
'scripts' => 'myExtension.js',
'styles' => 'myExtension.css',
'dependencies' => [ 'jquery.cookie', 'jquery.tabIndex' ],
'localBasePath' => __DIR__,
'remoteExtPath' => 'MyExtension',
];

Definition at line 3531 of file DefaultSettings.php.

◆ $wgResourceModuleSkinStyles

$wgResourceModuleSkinStyles = []

Skin-specific styles for resource modules.

These are later added to the 'skinStyles' list of the existing module. The 'styles' list can not be modified or disabled.

For example, here is a module "bar" and how skin Foo would provide additional styles for it.

Example:
'scripts' => 'resources/bar/bar.js',
'styles' => 'resources/bar/main.css',
];
'bar' => 'skins/Foo/bar.css',
];

This is mostly equivalent to:

Equivalent:
'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 them. This can be done using the+` prefix.

Example:
'scripts' => 'resources/bar/bar.js',
'styles' => 'resources/bar/basic.css',
'skinStyles' => [
'default' => 'resources/bar/additional.css',
],
];
// Note the '+' character:
'+bar' => 'skins/Foo/bar.css',
];

This is mostly equivalent to:

Equivalent:
'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, paths default to being relative to the MediaWiki root. You should always provide a localBasePath and remoteBasePath (or remoteExtPath/remoteSkinPath).

Example:
'bar' => 'bar.css',
'quux' => 'quux.css',
'remoteSkinPath' => 'Foo',
'localBasePath' => __DIR__,
];

◆ $wgResponsiveImages

$wgResponsiveImages = true

Generate and use thumbnails suitable for screens with 1.5 and 2.0 pixel densities.

This means a 320x240 use of an image on the wiki will also generate 480x360 and 640x480 thumbnails, output via the srcset attribute.

On older browsers, a JavaScript polyfill switches the appropriate images in after loading the original low-resolution versions depending on the reported window.devicePixelRatio. The polyfill can be found in the jquery.hidpi module.

$wgSemiprotectedRestrictionLevels = [ 'autoconfirmed' ]

Restriction levels that should be considered "semiprotected".

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".

'autoconfirmed' is quietly rewritten to 'editsemiprotected' for backwards compatibility. 'sysop' is not changed, since it really shouldn't be here.

◆ $wgSend404Code

$wgSend404Code = true

Some web hosts attempt to rewrite all responses with a 404 (not found) status code, mangling or hiding MediaWiki's output.

If you are using such a host, you should start looking for a better one. While you're doing that, set this to false to convert some of MediaWiki's 404 responses to 200 so that the generated error pages can be seen.

In cases where for technical reasons it is more important for MediaWiki to send the correct status code than for the body to be transmitted intact, this configuration variable is ignored.

◆ $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 wfGetLB() to access remote databases. Using wfGetLB() 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 8206 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)
  • 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.

◆ $wgThumbnailBuckets

$wgThumbnailBuckets = null

When defined, is an array of image widths used as buckets for thumbnail generation.

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.

The buckets generation is chained, with each bucket generated based on the above bucket when possible. File handlers have to opt into using that feature. For now only BitmapHandler supports it.

◆ $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.

Uploads to this wiki will NOT be put there - they will be put into $wgUploadDirectory. If $wgUseSharedUploads is set, the wiki will look in the shared repository if no file of the given name is found in the local repository (for [[File:..]], [[Media:..]] links). Thumbnails will also be looked for and generated in this directory.

Note that these configuration settings can now be defined on a per- repository basis for an arbitrary number of file repositories, using the $wgForeignFileRepos variable.

◆ $wgValidSkinNames

$wgValidSkinNames = []

List of valid skin names.

The key should be the name in all lower case, the value should be a properly cased name for the skin. 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.

Definition at line 7256 of file DefaultSettings.php.

◆ $wgVariantArticlePath

$wgVariantArticlePath = false

Like $wgArticlePath, but on multi-variant wikis, this provides a path format that describes which parts of the URL contain the language variant.

Example:
$wgArticlePath = '/wiki/$1';

A link to /wiki/ would be redirected to /sr/Главна_страна

It is important that $wgArticlePath not overlap with possible values of $wgVariantArticlePath.

◆ $wgVaryOnXFP

$wgVaryOnXFP = false

Add X-Forwarded-Proto to the Vary and Key headers for API requests and RSS/Atom feeds.

Use this if you have an SSL termination setup and need to split the cache between HTTP and HTTPS for API requests, feed requests and HTTP redirect responses in order to prevent cache pollution. This does not affect 'normal' requests to index.php other than HTTP redirects.

◆ $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', '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', ];

◆ $wgWANObjectCaches

$wgWANObjectCaches
Initial value:
= [
'class' => 'WANObjectCache',
'cacheId' => CACHE_NONE,
'channels' => []
]
]

Advanced WAN object cache configuration.

Each WAN cache wraps a registered object cache (for the local cluster) and it must also be configured to point to a PubSub instance. Subscribers must be configured to relay purges to the actual cache servers.

The format is an associative array where the key is a cache identifier, and the value is an associative array of parameters. The "cacheId" parameter is a cache identifier from $wgObjectCaches. The "channels" parameter is a map of actions ('purge') to PubSub channels defined in $wgEventRelayerConfig. The "loggroup" parameter controls where log events are sent.

◆ $wgWantedPagesThreshold

$wgWantedPagesThreshold = 1

Definition at line 2181 of file DefaultSettings.php.

◆ $wgWatchersMaxAge

$wgWatchersMaxAge = 180 * 24 * 3600

Page watchers inactive for more than this many seconds are considered inactive.

Used mainly by action=info. Default: 180 days = about six months.

Since
1.26

Definition at line 6688 of file DefaultSettings.php.

◆ $wgWhitelistRead

$wgWhitelistRead = false

Pages anonymous user may see, set as an array of pages titles.

Example:
$wgWhitelistRead = array ( "Main Page", "Wikipedia:Help");

Special:Userlogin and Special:ChangePassword are always whitelisted.

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 5063 of file DefaultSettings.php.

Referenced by Title\checkReadPermissions().

◆ $wgWhitelistReadRegexp

$wgWhitelistReadRegexp = false

Pages anonymous user may see, set as an array of regular expressions.

This function will match the regexp against the title name, which is without underscore.

Example:
To whitelist [[Main Page]]:
$wgWhitelistReadRegexp = [ "/Main Page/" ];
Note
Unless ^ and/or $ is specified, a regular expression might match pages not intended to be whitelisted. The above example will also whitelist 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]]
Note
This will only work if $wgGroupPermissions['*']['read'] is false – see below. Otherwise, ALL pages are accessible, regardless of this setting.

◆ $wgWikiDiff2MovedParagraphDetectionCutoff

$wgWikiDiff2MovedParagraphDetectionCutoff = 0

wikidiff2 supports detection of changes in moved paragraphs.

This setting controls the maximum number of paragraphs to compare before it bails out. Supported values:

  • 0: detection of moved paragraphs is disabled
  • int > 0: maximum number of paragraphs to compare Note: number of paragraph comparisons is in O(n^2). This setting is only effective if the wikidiff2 PHP/HHVM module is used as diffengine. See $wgExternalDiffEngine.

◆ $wgXhtmlDefaultNamespace

$wgXhtmlDefaultNamespace = null

The default xmlns attribute.

The option to define this has been removed. The value of this variable is no longer used by core and is set to a fixed value in Setup.php for compatibility with extensions that depend on the value of this variable being set. Such a dependency however is deprecated.

Deprecated:
since 1.22

Definition at line 3172 of file DefaultSettings.php.

◆ $wgXhtmlNamespaces

$wgXhtmlNamespaces = []

Permit other namespaces in addition to the w3.org default.

Use the prefix for the key and the namespace for the value.

Example:
$wgXhtmlNamespaces['svg'] = 'http://www.w3.org/2000/svg';
Normally we wouldn't have to define this in the root "<html>" element, but IE needs it there in some circumstances.

This is ignored if $wgMimeType is set to a non-XML MIME type.
