$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.

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

Definition at line 8118 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'] = [

$wgAutoConfirmAge

$wgAutoConfirmAge = 0

Number of seconds an account is required to age before it's given the implicit 'autoconfirm' group membership.

This can be used to limit privileges of new accounts.

Accounts created by earlier versions of the software may not have a recorded creation date, and will always be considered to pass the age test.

When left at 0, all registered accounts will pass.

Example:

Set automatic confirmation to 10 minutes (which is 600 seconds):

$wgAutoConfirmAge = 600;     // ten minutes

Set age to one day:

$wgAutoConfirmAge = 3600*24; // one day

$wgAutoloadClasses

$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 = 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.

= [
    '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://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
• 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: 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:

= [

    ]
]

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.

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.

$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.

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

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

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

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

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

$wgForceHTTPS

bool $wgForceHTTPS = false

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

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

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

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

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

$wgForceUIMsgAsContentMsg

$wgForceUIMsgAsContentMsg = []

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

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

Example:

To allow language-specific main page and community portal:

$wgForceUIMsgAsContentMsg = [ 'mainpage', 'portal-url' ];

$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
• '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.

$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!

Definition at line 5123 of file DefaultSettings.php.

$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:

$wgGroupsRemoveFromSelf = [ '*' => true ];

This allows users in the '*' group (i.e. any user) to remove themselves from any group that they happen to be in.

$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.

$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:

  $wgHooks['event_name'][] = [ $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:

$wgHTCPRouting = [
        '|^https?://upload\\.wikimedia\\.org|' => [
                'host' => '239.128.0.113',
                'port' => 4827,
        ],
        '' => [

                '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 = [
    '' => [
        // 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' ],

$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.

$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.

or:

if ( wgIsArticle ) { ... }

Instead, one needs to use mw.config.

$wgLegacySchemaConversion

$wgLegacySchemaConversion = false

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.

$wgLegalTitleChars

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

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

Problematic punctuation:

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

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

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

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

$wgLocalFileRepo

$wgLocalFileRepo = false

File repository structures.

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

Properties required for all repos:

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

For most core repos:

• zones Associative array of zone names that each map to an array with: container : backend container name the zone is in directory : root path within container for the zone url : base URL to the root of the zone urlsByExt : map of file extension types to base URLs (useful for using a different cache for videos) Zones default to using "<repo name>-<zone name>" as the container name and default to using the container root as the zone's root directory. Nesting of zone locations within other zones should be avoided.
• url Public zone URL. The 'zones' settings take precedence.
• hashLevels The number of directory levels for hash-based division of files
• thumbScriptUrl The URL for thumb.php (optional, not recommended)
• transformVia404 Whether to skip media file transformation on parse and rely on a 404 handler instead.
• initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE], determines whether filenames implicitly start with a capital letter. The current implementation may give incorrect description page links when the local $wgCapitalLinks and initialCapital are mismatched.
• pathDisclosureProtection May be 'paranoid' to remove all parameters from error messages, 'none' to leave the paths in unchanged, or 'simple' to replace paths with placeholders. Default for LocalRepo is 'simple'.
• fileMode This allows wikis to set the file mode when uploading/moving files. Default is 0644.
• directory The local filesystem directory where public files are stored. Not used for some remote repos.
• thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
• thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
• isPrivate Set this if measures should always be taken to keep the files private. One should not trust this to assure that the files are not web readable; the server configuration should be done manually depending on the backend.

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

• descBaseUrl URL of image description pages, e.g. https://en.wikipedia.org/wiki/File:
• scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g. https://en.wikipedia.org/w
• articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
• fetchDescription Fetch the text of the remote file description page. 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.

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.

$wgPasswordPolicy

$wgPasswordPolicy

Password policy for local wiki users.

A user's effective policy is the superset of all policy statements from the policies for the groups where the user is a member. If more than one group policy include the same policy statement, the value is the max() of the values. Note true > false. The 'default' policy group is required, and serves as the minimum policy for all users. 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, or offered a chance to reset their password as part of the login workflow, regardless if it is correct.
• MaximalPasswordLength - maximum length password a user is allowed to attempt. Prevents DoS attacks with pbkdf2.
• PasswordCannotMatchUsername - Password cannot match username to
• PasswordCannotMatchBlacklist - Username/password combination cannot match a specific, hardcoded blacklist.
• PasswordCannotBePopular - Blacklist passwords which are known to be commonly chosen. Set to integer n to ban the top n passwords. If you want to ban all common passwords on file, use the PHP_INT_MAX constant.

$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.

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:

$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 3752 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 3762 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 3552 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:

$wgResourceModules['bar'] = [
  'scripts' => 'resources/bar/bar.js',
  'styles' => 'resources/bar/main.css',
];
 
$wgResourceModuleSkinStyles['foo'] = [
  'bar' => 'skins/Foo/bar.css',
];

This is mostly equivalent to:

Equivalent:

$wgResourceModules['bar'] = [
  'scripts' => 'resources/bar/bar.js',
  'styles' => 'resources/bar/main.css',
  'skinStyles' => [
    'foo' => skins/Foo/bar.css',
  ],
];

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

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

Example:

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

This is mostly equivalent to:

Equivalent:

$wgResourceModules['bar'] = [
  'scripts' => 'resources/bar/bar.js',
  'styles' => 'resources/bar/basic.css',
  'skinStyles' => [
    'default' => 'resources/bar/additional.css',
    'foo' => [
      'resources/bar/additional.css',
      'skins/Foo/bar.css',
    ],
  ],
];

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

As with $wgResourceModules, paths default to being relative to the MediaWiki root. You should always provide a localBasePath and remoteBasePath (or remoteExtPath/remoteSkinPath).

Example:

$wgResourceModuleSkinStyles['foo'] = [
  '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.

$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.

$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

$wgShellLocale

$wgShellLocale = 'C.UTF-8'

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

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

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

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

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

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

Note

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

$wgThumbnailBuckets

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

$wgThumbnailMinimumBucketDistance

$wgThumbnailMinimumBucketDistance = 50

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

$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.

$wgUploadThumbnailRenderMap

$wgUploadThumbnailRenderMap = []

When defined, is an array of thumbnail widths to be rendered at upload time.

= ( strpos( PHP_SAPI, 'cgi' ) === false ) &&

Whether to support URLs like index.php/Page_title These often break when PHP is set up in CGI mode.

PATH_INFO may be correct if cgi.fix_pathinfo is set, but then again it may not; lighttpd converts incoming path data to lowercase on systems with case-insensitive filesystems, and there have been reports of problems on Apache as well.

To be safe we'll continue to keep it off by default.

Override this to false if $_SERVER['PATH_INFO'] contains unexpectedly incorrect garbage, or to true if it is really correct.

The default $wgArticlePath will be set based on this value at runtime, but if you have customized it, having this incorrectly set to true can cause redirect loops when "pretty URLs" are used.

        # 'domain' is set to $wgCanonicalServer in Setup.php
        'forwardCookies' => false,
        'HTTPProxy' => null
    ]
]

Global configuration variable for Virtual REST Services.

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

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

Auto-mounting example for Parsoid:

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

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

Example config for Parsoid:

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

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.
