Detailed Description

This class contains schema declarations for all configuration variables known to MediaWiki core.

The schema definitions follow the JSON Schema specification.

See also: https://json-schema.org/learn/getting-started-step-by-step.html; https://json-schema.org/understanding-json-schema/

The following JSON schema keys are used by MediaWiki:

default: the configuration variable's default value.
type: identifies the allowed value type or types. In addition to JSON Schema types, PHPDoc style type definitions are supported for convenience. Note that 'array' must not be used for associative arrays. To avoid confusion, use 'list' for sequential arrays and 'map' for associative arrays with uniform values. The 'object' type should be used for structures that have a known set of meaningful properties, especially if each property may have a different kind of value. See MediaWiki\\Settings\\Source\\JsonTypeHelper for details.

The following additional keys are used by MediaWiki:

mergeStrategy: see the MediaWiki\\Settings\\Config\\MergeStrategy.
dynamicDefault: Specified a callback that computes the effective default at runtime, based on the value of other config variables or on the system environment. See MediaWiki\\Settings\\Source\\ReflectionSchemaSource and MediaWiki\\Settings\\DynamicDefaultValues for details.

Note: After changing this file, run maintenance/generateConfigSchema.php to update all the files derived from the information in MainConfigSchema.

◆ AllowExternalImagesFrom

const MediaWiki\MainConfigSchema::AllowExternalImagesFrom

Initial value:

= [
        'default' => '',
    ]

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

Image URLs that start with this string are then rendered, while all others are not.

You can use this to set up a trusted, simple repository of images. You may also specify an array of strings to allow multiple sites

Examples:

$wgAllowExternalImagesFrom = 'http://127.0.0.1/';

$wgAllowExternalImagesFrom = [ 'http://127.0.0.1/', 'http://example.com' ];

$wgAllowExternalImagesFrom

Config variable stub for the AllowExternalImagesFrom setting, for use by phpdoc and IDEs.

Initial value:

= [
        'default' => false,
        'deprecated' => 'since 1.35; register an extension tag named <img> instead.',
    ]

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.

Deprecated: since 1.35; register an extension tag named

instead.

Definition at line 6338 of file MainConfigSchema.php.

◆ AllowRequiringEmailForResets

const MediaWiki\MainConfigSchema::AllowRequiringEmailForResets

◆ AllowSecuritySensitiveOperationIfCannotReauthenticate

const MediaWiki\MainConfigSchema::AllowSecuritySensitiveOperationIfCannotReauthenticate

Initial value:

        'type' => 'map',
        'additionalProperties' => [ 'type' => 'boolean', ],
    ]

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.

= [
        'default' => 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.

Initial value:

= [
        'default' => [
            # 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',
            ],
        ],
        'type' => 'map',
    ]

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.

const MediaWiki\MainConfigSchema::ApiFrameOptions

Initial value:

= [
        'default' => '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.

◆ APIModules

const MediaWiki\MainConfigSchema::APIModules

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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 ) { ... }
];

enabled: (bool) Whether auto-creation is enabled.
actions: (array) A list of actions for which the feature is enabled. Currently only "edit" is supported.
genPattern: (string) The pattern used when generating new usernames. This should have "$1" indicating the place where the serial string will be substituted.
matchPattern: (string) The pattern used when determining whether a username is a temporary user. This affects the rights of the user and also prevents explicit creation of users with matching names.
serialProvider: (array) Configuration for generation of unique integer indexes which are used to make temporary usernames.
- type: (string) May be "local" to allocate indexes using the local database. If the CentralAuth extension is enabled, it may be "centralauth". Extensions may plug in additional types using the TempUserSerialProviders attribute.
- numShards (int, default 1): A small integer. This can be set to a value greater than 1 to avoid acquiring a global lock when allocating IDs, at the expense of making the IDs be non-monotonic.
serialMapping: (array) Configuration for mapping integer indexes to strings to substitute into genPattern.
- type: (string) May be
  - "plain-numeric" to use ASCII decimal numbers
  - "localized-numeric" to use numbers localized using a specific language
  - "filtered-radix" to use numbers in an arbitrary base between 2 and 36, with an optional list of "bad" IDs to skip over.
  - "scramble": to use ASCII decimal numbers that are short but non-consecutive.
- language: (string) With "localized-numeric", the language code
- radix: (int) With "filtered-radix", the base
- badIndexes: (array) With "filtered-radix", an array with the bad unmapped indexes in the values. The integers must be sorted and the list must never change after the indexes have been allocated. The keys must be zero-based array indexes.
- uppercase: (bool) With "filtered-radix", whether to use uppercase letters, default false.

◆ AutoloadAttemptLowercase

const MediaWiki\MainConfigSchema::AutoloadAttemptLowercase

Initial value:

= [
        'default' => false,
        'deprecated' => 'since 1.35',
    ]

Switch controlling legacy case-insensitive classloading.

Do not disable if your wiki must support data created by PHP4, or by MediaWiki 1.4 or earlier.

Deprecated: since 1.35

Definition at line 10871 of file MainConfigSchema.php.

◆ Autopromote

const MediaWiki\MainConfigSchema::Autopromote

Initial value:

= [
        'default' => [
                'autoconfirmed' => [ '&',
                    [ APCOND_EDITCOUNT, null ], 
                    [ APCOND_AGE, null ], 
                ],
            ],
        'type' => 'map',
    ]

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

The basic syntax for $wgAutopromote is:

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

A cond may be:

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

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

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

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

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

    ]

Automatically add a usergroup to any user who matches certain conditions.

Does not add the user to the group again if it has been removed. Also, does not remove the group if the user no longer meets the criteria.

The format is:

[ event => criteria, ... ]

Where event is either:

'onEdit' (when user edits)

Criteria has the same format as $wgAutopromote

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

A list of available rights, in addition to the ones defined by the core.

For extensions only.

Definition at line 8116 of file MainConfigSchema.php.

◆ BaseDirectory

const MediaWiki\MainConfigSchema::BaseDirectory

Initial value:

= [
        'default' => null,
    ]

Absolute filesystem path of the root directory of the MediaWiki installation.

The MW_INSTALL_PATH environment variable can be used to set this.

Note: Automatically set in Setup.php before loading local settings.; Do not modify in settings files! Must remain equal to the MW_INSTALL_PATH constant defined in Setup.php.

Since: 1.38

◆ BlockAllowsUTEdit

const MediaWiki\MainConfigSchema::BlockAllowsUTEdit

Initial value:

= [
        'default' => true,
    ]

Set this to true to allow blocked users to edit their own user talk page.

This only applies to sitewide blocks. Partial blocks always allow users to edit their own user talk page unless otherwise specified in the block restrictions.

Definition at line 7472 of file MainConfigSchema.php.

◆ BlockCIDRLimit

const MediaWiki\MainConfigSchema::BlockCIDRLimit

Initial value:

= [
        'default' => [
            'IPv4' => 16,
            'IPv6' => 19,
        ],
        'type' => 'map',
    ]

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.

◆ BlockDisablesLogin

const MediaWiki\MainConfigSchema::BlockDisablesLogin

Initial value:

= [
        'default' => false,
    ]

If true, blocked users will not be allowed to login.

When using this with a public wiki, the effect of logging out blocked users may actually be avers: unless the user's address is also blocked (e.g. auto-block), logging the user out will again allow reading and editing, just as for anonymous visitors.

        'type' => 'string',
    ]

Override ability of certains browsers to attempt to autodetect dataformats in pages.

This is a default feature of many mobile browsers, but can have a lot of false positives, where for instance year ranges are confused with phone numbers. The default of this setting is to disable telephone number data detection. Set BrowserFormatDetection to false to fallback to browser defaults.

Initial value:

= [
        'default' => false,
    ]

Directory for caching data in the local filesystem.

◆ CapitalLinkOverrides

const MediaWiki\MainConfigSchema::CapitalLinkOverrides

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Since: 1.16 - This can now be set per-namespace. Some special namespaces (such as Special, see NamespaceInfo::$alwaysCapitalizedNamespaces for the full list) must be true by default (and setting them has no effect), due to various things that require them to be so. Also, since Talk namespaces need to directly mirror their associated content namespaces, the values for those are ignored in favor of the subject namespace's setting. Setting for NS_MEDIA is taken automatically from NS_FILE.

Example:

$wgCapitalLinkOverrides[ NS_FILE ] = false;

NS_FILE

const NS_FILE

Definition Defines.php:70

$wgCapitalLinkOverrides

Config variable stub for the CapitalLinkOverrides setting, for use by phpdoc and IDEs.

◆ CapitalLinks

const MediaWiki\MainConfigSchema::CapitalLinks

Initial value:

= [
        'default' => true,
    ]

Set this to false to avoid forcing the first letter of links to capitals.

Warning: may break links! This makes links COMPLETELY case-sensitive. Links appearing with a capital at the beginning of a sentence will not go to the same place as links in the middle of a sentence using a lowercase initial.

◆ CascadingRestrictionLevels

const MediaWiki\MainConfigSchema::CascadingRestrictionLevels

Initial value:

= [
        'default' => [ 'sysop', ],
        'type' => 'list',
    ]

Restriction levels that can be used with cascading protection.

A page can only be protected with cascading protection if the requested restriction level is included in this array.

'autoconfirmed' is quietly rewritten to 'editsemiprotected' for backwards compatibility. 'sysop' is quietly rewritten to 'editprotected' for backwards compatibility.

◆ CategoryCollation

const MediaWiki\MainConfigSchema::CategoryCollation

Initial value:

= [
        'default' => 'uppercase',
    ]

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

A sorting scheme is also known as a collation.

Available values are:

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

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

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

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

◆ CategoryMagicGallery

const MediaWiki\MainConfigSchema::CategoryMagicGallery

Initial value:

= [
        'default' => true,

◆ CdnMatchParameterOrder

const MediaWiki\MainConfigSchema::CdnMatchParameterOrder

Initial value:

= [
        'default' => true,
    ]

Set this to false if MediaWiki is behind a CDN that re-orders query parameters on incoming requests.

MediaWiki sets a large 'Cache-Control: s-maxage=' directive on page views only if the request URL matches one of the normal CDN URL forms. When 'CdnMatchParameterOrder' is false, the matching algorithm ignores the order of URL parameters.

Since: 1.39

◆ CdnMaxAge

const MediaWiki\MainConfigSchema::CdnMaxAge

Initial value:

= [
        'default' => 18000,
    ]

Cache TTL for the CDN sent as s-maxage (without ESI) or Surrogate-Control (with ESI).

Without ESI, you should strip out s-maxage in the CDN config.

18000 seconds = 5 hours, more cache hits with 2678400 = 31 days.

Since: 1.34 Renamed from $wgSquidMaxage

◆ CdnMaxageLagged

const MediaWiki\MainConfigSchema::CdnMaxageLagged

◆ CdnReboundPurgeDelay

const MediaWiki\MainConfigSchema::CdnReboundPurgeDelay

Initial value:

= [
        'default' => 0,
    ]

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

This requires delayed job support.

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

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

Definition at line 4387 of file MainConfigSchema.php.

◆ CdnServers

const MediaWiki\MainConfigSchema::CdnServers

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

List of proxy servers to purge on changes; default port is 80.

Use IP addresses.

When MediaWiki is running behind a proxy, it will trust X-Forwarded-For headers sent/modified from these proxies when obtaining the remote IP address

For a list of trusted servers which aren't purged, see $wgSquidServersNoPurge.

Since: 1.34 Renamed from $wgSquidServers.

            'use' => [ 'SharedDB', 'SharedPrefix', 'SharedTables', 'DBname', 'DBprefix' ]
        ],
    ]

Cookies generated by MediaWiki have names starting with this prefix.

    ]

Whether the "secure" flag should be set on the cookie.

This can be:

true: Set secure flag
false: Don't set secure flag
"detect": Set the secure flag if $wgServer is set to an HTTPS URL, or if $wgForceHTTPS is true.

If $wgForceHTTPS is true, session cookies will be secure regardless of this setting. However, other cookies will still be affected.

◆ CookieSetOnAutoblock

const MediaWiki\MainConfigSchema::CookieSetOnAutoblock

Initial value:

= [
        'default' => true,
    ]

Whether to set a cookie when a user is autoblocked.

Doing so means that a blocked user, even after logging out and moving to a new IP address, will still be blocked. This cookie will contain an authentication code if $wgSecretKey is set, or otherwise will just be the block ID (in which case there is a possibility of an attacker discovering the names of revdeleted users, so it is best to use this in conjunction with $wgSecretKey being set).

Definition at line 9114 of file MainConfigSchema.php.

◆ CookieSetOnIpBlock

const MediaWiki\MainConfigSchema::CookieSetOnIpBlock

Initial value:

= [
        'default' => true,

const MediaWiki\MainConfigSchema::CriticalSectionTimeLimit

Initial value:

= [
        'default' => 180.0,
        'type' => 'float',
    ]

The maximum time critical sections are allowed to stay open.

Critical sections are used to defer Excimer request timeouts. If Excimer is available and this time limit is exceeded, an exception will be thrown at the next opportunity, typically after a long-running function like a DB query returns.

Critical sections may wrap long-running queries, and it's generally better for the timeout to be handled a few milliseconds later when the critical section exits, so this should be a large number.

This limit is ignored in command-line mode.

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

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

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

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

The first server listed in this array (with key 0) will be the primary. 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 primaries, and then set read_only=0 on primaries at runtime.

Initial value:

= [
        'default' => false,
    ]

WARNING: SECURITY THREAT - debug use only.

Disables many security checks in the API for debugging purposes. This flag should never be used on the production servers, as it introduces a number of potential security holes. Even when enabled, the validation will still be performed, but instead of failing, API will return a warning. Also, there will always be a warning notifying that this flag is set. At this point, the flag allows GET requests to go through for modules requiring POST.

◆ DebugComments

const MediaWiki\MainConfigSchema::DebugComments

Initial value:

= [
        'default' => false,
    ]

Send debug data to an HTML comment in the output.

This may occasionally be useful when supporting a non-technical end-user. It's more secure than exposing the debug log file to the web, since the output only contains private data for the current user. But it's not ideal for development use since data is lost on fatal errors and redirects.

Definition at line 9193 of file MainConfigSchema.php.

◆ DebugDumpSql

const MediaWiki\MainConfigSchema::DebugDumpSql

Initial value:

= [
        'default' => false,

◆ DebugLogFile

const MediaWiki\MainConfigSchema::DebugLogFile

Initial value:

= [
        'default' => '',
    ]

Enable verbose debug logging for all channels and log levels.

See https://www.mediawiki.org/wiki/How_to_debug

For static requests, this enables all channels and warning-level and above only. Use $wgDebugRawPage to make those verbose as well.

The debug log file should be not be web-accessible if it is used in a production environment, as may contain private data.

Definition at line 9147 of file MainConfigSchema.php.

◆ DebugLogGroups

const MediaWiki\MainConfigSchema::DebugLogGroups

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Map of string log group names to log destinations.

If set, wfDebugLog() output for that group will go to that file instead of the regular $wgDebugLogFile. Useful for enabling selective logging in production.

Log destinations may be one of the following:

false to completely remove from the output, including from $wgDebugLogFile.
string values specifying a filename or URI.
associative array with keys:
- 'destination' desired filename or URI.
- 'sample' an integer value, specifying a sampling factor (optional)
- 'level' A \Psr\Log\LogLevel constant, indicating the minimum level to log (optional, since 1.25)

◆ DebugRawPage

const MediaWiki\MainConfigSchema::DebugRawPage

Initial value:

= [
        'default' => false,
    ]

If true, debug logging is also enabled for load.php and action=raw requests.

By default, $wgDebugLogFile enables all channels and warning-level and above for static requests.

This ensures that the debug log is likely a chronological record of of specific web request you are debugging, instead of overlapping with messages from static requests, which would make it unclear which message originated from what request.

Also, during development this can make browsing and JavaScript testing considerably slower (T85805).

Initial value:

= [
        'default' => 'DENY',
    ]

This prevents those pages from being displayed in a frame or iframe. The options are:

'DENY': Do not allow framing. This is recommended for most wikis.
- 'SAMEORIGIN': Allow framing by pages on the same domain. This can be used to allow framing within a trusted domain. This is insecure if there is a page on the same domain which allows framing of arbitrary URLs.
- false: Allow all framing. This opens up the wiki to XSS attacks and thus full compromise of local user accounts. Private wikis behind a corporate firewall are especially vulnerable. This is not recommended.

For extra safety, set $wgBreakFrames = true, to prevent framing on all pages, not just edit pages.

Definition at line 8817 of file MainConfigSchema.php.

const MediaWiki\MainConfigSchema::EnableSidebarCache

Initial value:

= [
        'default' => false,
    ]

If on, the sidebar navigation links are cached for users with the current language set.

This can save a touch of load on a busy site by shaving off extra message lookups.

However it is also fragile: changing the site configuration, or having a variable $wgArticlePath, can produce broken links that don't update as expected.

Definition at line 4225 of file MainConfigSchema.php.

const MediaWiki\MainConfigSchema::EnableWANCacheReaper

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Verify and enforce WAN cache purges using reliable DB sources as streams.

These secondary cache purges are de-duplicated via simple cache mutexes. This improves consistency when cache purges are lost, which becomes more likely as more cache servers are added or if there are multiple datacenters. Only keys related to important mutable content will be checked.

Since: 1.29

Definition at line 3910 of file MainConfigSchema.php.

◆ EnotifFromEditor

const MediaWiki\MainConfigSchema::EnotifFromEditor

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Allow sending of e-mail notifications with the editor's address as sender.

This setting depends on $wgEnotifRevealEditorAddress also being enabled. If both are enabled, notifications for actions from users that have opted-in, will be sent to other users with their address as "From" instead of "Reply-To".

If disabled, or not opted-in, notifications come from $wgPasswordSender.

Definition at line 2669 of file MainConfigSchema.php.

◆ EnotifImpersonal

const MediaWiki\MainConfigSchema::EnotifImpersonal

Initial value:

= [
        'default' => false,
    ]

Send a generic mail instead of a personalised mail for each user.

This always uses UTC as the time zone, and doesn't include the username.

For pages with many users watching, this can significantly reduce mail load. Has no effect when using sendmail rather than SMTP.

Definition at line 2743 of file MainConfigSchema.php.

◆ EnotifMaxRecips

const MediaWiki\MainConfigSchema::EnotifMaxRecips

Initial value:

= [
        'default' => 500,

Definition at line 2751 of file MainConfigSchema.php.

◆ EnotifMinorEdits

const MediaWiki\MainConfigSchema::EnotifMinorEdits

Initial value:

= [
        'default' => true,
    ]

Potentially send notification mails on minor edits to pages.

This is enabled by default. If this is false, users will never be notified on minor edits.

If it is true, editors with the 'nominornewtalk' right (typically bots) will still not trigger notifications for minor edits they make (to any page, not just user talk).

Finally, if the watcher/recipient has the 'enotifminoredits' user preference set to false, they will not receive notifications for minor edits.

User talk notifications are also affected by $wgEnotifMinorEdits, the above settings, $wgEnotifUserTalk, and the preference described there.

Definition at line 2732 of file MainConfigSchema.php.

◆ EnotifRevealEditorAddress

const MediaWiki\MainConfigSchema::EnotifRevealEditorAddress

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Allow sending of e-mail notifications with the editor's address in "Reply-To".

Note, enabling this only actually uses it in notification e-mails if the user opted-in to this feature. This feature flag also controls visibility of the 'enotifrevealaddr' preference, which, if users opt into, will make e-mail notifications about their actions use their address as "Reply-To".

To set the address as "From" instead of "Reply-To", also enable $wgEnotifFromEditor.

If disabled, or not opted-in, notifications come from $wgPasswordSender.

Definition at line 2714 of file MainConfigSchema.php.

◆ EnotifUseRealName

const MediaWiki\MainConfigSchema::EnotifUseRealName

Initial value:

= [
        'default' => false,

◆ EventRelayerConfig

const MediaWiki\MainConfigSchema::EventRelayerConfig

Initial value:

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

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

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

Some extensions may want to use "channel categories" so that different channels can also share the same custom relayer instance (e.g. when it's likely to be overridden). 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.

= [
        'default' => null,
        'type' => '?list',
    ]

An array of namespace keys in which the INDEX/__NOINDEX__ magic words will not function, so users can't decide whether pages in that namespace are indexed by search engines.

◆ ExportAllowHistory

const MediaWiki\MainConfigSchema::ExportAllowHistory

Initial value:

= [
        'default' => true,
    ]

If set to false, disables the full-history option on Special:Export.

This is currently poorly optimized for long edit histories, so is disabled on Wikimedia's sites.

Definition at line 10605 of file MainConfigSchema.php.

◆ ExportAllowListContributors

const MediaWiki\MainConfigSchema::ExportAllowListContributors

Initial value:

= [

◆ ExportMaxHistory

const MediaWiki\MainConfigSchema::ExportMaxHistory

Initial value:

= [

◆ ExportMaxLinkDepth

const MediaWiki\MainConfigSchema::ExportMaxLinkDepth

Initial value:

= [
        'default' => 0,
    ]

If non-zero, Special:Export accepts a "pagelink-depth" parameter up to this specified level, which will cause it to include all pages linked to from the pages you specify.

Since this number can become really really large and could easily break your wiki, it's disabled by default for now.

Warning: There's a HARD CODED limit of 5 levels of recursion to prevent a crazy-big export from being done by someone setting the depth number too high. In other words, last resort safety net.

Initial value:

= [
        'default' => 180 * 86400,
    ]

Default login cookie lifetime, in seconds.

Setting $wgExtendLoginCookieExpiration to null will use $wgCookieExpiration to calculate the cookie lifetime. As with $wgCookieExpiration, 0 will make login cookies session-only.

◆ ExtensionCredits

const MediaWiki\MainConfigSchema::ExtensionCredits

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Add information about an installed extension, keyed by its type.

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

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

$wgExtensionCredits['other'][] = [
    'path' => __FILE__,
    'name' => 'Example extension',
    'namemsg' => 'exampleextension-name',
    'author' => [
        'Foo Barstein',
    ],
    'version' => '0.0.1',
    'url' => 'https://example.org/example-extension/',
    'descriptionmsg' => 'exampleextension-desc',
    'license-name' => 'GPL-2.0-or-later',
];

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

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

◆ ExtensionFunctions

const MediaWiki\MainConfigSchema::ExtensionFunctions

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

A list of callback functions which are called once MediaWiki is fully initialised.

Definition at line 10713 of file MainConfigSchema.php.

◆ ExtensionInfoMTime

const MediaWiki\MainConfigSchema::ExtensionInfoMTime

Initial value:

= [
        'default' => false,
        'type' => 'integer|false',
    ]

When loading extensions through the extension registration system, this can be used to invalidate the cache.

A good idea would be to set this to one file, you can just touch that one to invalidate the cache

Example:

$wgExtensionInfoMTime = filemtime( "$IP/LocalSettings.php" );

$wgExtensionInfoMTime

Config variable stub for the ExtensionInfoMTime setting, for use by phpdoc and IDEs.

Definition config-vars.php:1620

If set to false, the mtime for each individual JSON file will be checked, which can be slow if a large number of extensions are being loaded.

Definition at line 4273 of file MainConfigSchema.php.

◆ ExtensionMessagesFiles

const MediaWiki\MainConfigSchema::ExtensionMessagesFiles

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Extension messages files.

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

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

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

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

Example:

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

$wgExtensionMessagesFiles

◆ ExternalInterwikiFragmentMode

const MediaWiki\MainConfigSchema::ExternalInterwikiFragmentMode

Initial value:

= [
        'default' => 'legacy',
    ]

Which ID escaping mode should be used for external interwiki links? See documentation for $wgFragmentMode above for details of each mode.

Because you can't control external sites, this setting should probably always be 'legacy', unless every wiki you link to has converted to 'html5'.

Since: 1.30

Definition at line 5143 of file MainConfigSchema.php.

◆ ExternalLinkTarget

const MediaWiki\MainConfigSchema::ExternalLinkTarget

Initial value:

= [
        'default' => false,
    ]

Set a default target for external links, e.g.

_blank to pop up a new window.

This will also set the "noreferrer" and "noopener" link rel to prevent the attack described at https://mathiasbynens.github.io/rel-noopener/ . Some older browsers may not support these link attributes, hence setting $wgExternalLinkTarget to _blank may represent a security risk to some of your users.

Definition at line 6423 of file MainConfigSchema.php.

◆ ExternalServers

const MediaWiki\MainConfigSchema::ExternalServers

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Shortcut for setting $wgLBFactoryConf["externalClusters"].

This is only applicable when using the default LBFactory of LBFactorySimple. It is ignored if a different LBFactory is set, or if externalClusters is already set explicitly.

See also: ExternalStoreAccess

Example: Create a cluster named 'blobs_cluster1':

$wgExternalServers = [
    'blobs_cluster1' => <array in the same format as $wgDBservers>

◆ ExtraGenderNamespaces

const MediaWiki\MainConfigSchema::ExtraGenderNamespaces

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Same as above, but for namespaces with gender distinction.

Note: the default form for the namespace should also be set using $wgExtraNamespaces for the same index.

◆ ExtraInterlanguageLinkPrefixes

const MediaWiki\MainConfigSchema::ExtraInterlanguageLinkPrefixes

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

List of additional interwiki prefixes that should be treated as interlanguage links (i.e.

placed in the sidebar).

Notes:

This will not do anything unless the prefixes are defined in the interwiki map.
The display text for these custom interlanguage links will be fetched from the system message "interlanguage-link-xyz" where xyz is the prefix in this array.
A friendly name for each site, used for tooltip text, may optionally be placed in the system message "interlanguage-link-sitename-xyz" where xyz is the prefix in this array.

Definition at line 4618 of file MainConfigSchema.php.

◆ ExtraLanguageCodes

const MediaWiki\MainConfigSchema::ExtraLanguageCodes

Initial value:

= [
        'default' => [
            'bh' => 'bho',
            'no' => 'nb',
            'simple' => 'en',
        ],
        'type' => 'map',
    ]

List of mappings from one language code to another.

This array makes the codes not appear as a selectable language on the installer.

In Setup.php, the variable $wgDummyLanguageCodes is created by combining these codes with a list of "deprecated" codes, which are mostly leftovers from renames or other legacy things, and the internal codes 'qqq' and 'qqx'. If a mapping in $wgExtraLanguageCodes collide with a built-in mapping, the value in $wgExtraLanguageCodes will be used.

Since: 1.29

Definition at line 4657 of file MainConfigSchema.php.

◆ ExtraLanguageNames

const MediaWiki\MainConfigSchema::ExtraLanguageNames

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

List of language names or overrides for default names in Names.php.

Definition at line 4638 of file MainConfigSchema.php.

◆ ExtraNamespaces

const MediaWiki\MainConfigSchema::ExtraNamespaces

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Additional namespaces.

If the namespaces defined in Language.php and Namespace.php are insufficient, you can create new ones here, for example, to import Help files in other languages. You can also override the namespace names of existing namespaces. Extensions should use the CanonicalNamespaces hook or extension.json.

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.

Example:

$wgExtraNamespaces = [
   100 => "Hilfe",
   101 => "Hilfe_Diskussion",
   102 => "Aide",
   103 => "Discussion_Aide"
];

◆ ExtraSignatureNamespaces

const MediaWiki\MainConfigSchema::ExtraSignatureNamespaces

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

Array of namespaces, in addition to the talk namespaces, where signatures (~~~~) are likely to be used.

This determines whether to display the Signature button on the edit toolbar, and may also be used by extensions.

For example, "traditional" style wikis, where content and discussion are intermixed, could place NS_MAIN and NS_PROJECT namespaces in this array.

Definition at line 6082 of file MainConfigSchema.php.

◆ FallbackSkin

const MediaWiki\MainConfigSchema::FallbackSkin

◆ FeedCacheTimeout

const MediaWiki\MainConfigSchema::FeedCacheTimeout

Initial value:

= [
        'default' => 60,
    ]

Minimum timeout for cached Recentchanges feed, in seconds.

A cached version will continue to be served out even if changes are made, until this many seconds runs out since the last render.

If set to 0, feed caching is disabled. Use this for debugging only; feed generation can be pretty slow with diffs.

◆ FileBackends

const MediaWiki\MainConfigSchema::FileBackends

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

File backend structure configuration.

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

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

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

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

There are two particularly important aspects about each backend:

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

◆ FileCacheDepth

const MediaWiki\MainConfigSchema::FileCacheDepth

Initial value:

= [
        'default' => 2,
    ]

Depth of the subdirectory hierarchy to be created under $wgFileCacheDirectory.

The subdirectories will be named based on the MD5 hash of the title. A value of 0 means all cache files will be put directly into the main file cache directory.

Definition at line 4204 of file MainConfigSchema.php.

◆ FileCacheDirectory

const MediaWiki\MainConfigSchema::FileCacheDirectory

Initial value:

= [
        'default' => false,
        'dynamicDefault' => [ 'use' => [ 'UploadDirectory' ] ]
    ]

Directory where the cached page will be saved.

Defaults to "{$wgUploadDirectory}/cache".

Initial value:

= [
        'default' => [ 'png', 'gif', 'jpg', 'jpeg', 'webp', ],
        'type' => 'list',
    ]

This is the list of preferred extensions for uploading files.

Uploading files with extensions not in this list will trigger a warning.

Warning: If you add any OpenOffice or Microsoft Office file formats here, such as odt or doc, and untrusted users are allowed to upload files, then your wiki will be vulnerable to cross-site request forgery (CSRF).

Definition at line 1594 of file MainConfigSchema.php.

◆ FilterLogTypes

const MediaWiki\MainConfigSchema::FilterLogTypes

Initial value:

= [
        'default' => [

            'newusers' => false,
        ],
        'type' => 'map',
    ]

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 logeventslist-[type]-log should be added, and will be used for the link text.

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.

◆ ForceDeferredUpdatesPreSend

const MediaWiki\MainConfigSchema::ForceDeferredUpdatesPreSend

Initial value:

= [
        'default' => false,
    ]

Force deferred updates to be run before sending a response to the client, instead of attempting to run them after sending the response.

Setting this to true is useful for end-to-end testing, to ensure that the effects of a request are visible to any subsequent requests, even if they are made immediately after the first one. Note however that this does not ensure that database replication is complete, nor does it execute any jobs enqueued for later. There should be no reason to set this in a normal production environment.

◆ ForcedRawSMaxage

const MediaWiki\MainConfigSchema::ForcedRawSMaxage

Initial value:

Default maximum age for raw CSS/JS accesses.

300 seconds = 5 minutes.

◆ ForceHTTPS

const MediaWiki\MainConfigSchema::ForceHTTPS

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

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.

$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.

◆ ForceUIMsgAsContentMsg

const MediaWiki\MainConfigSchema::ForceUIMsgAsContentMsg

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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' ];

◆ ForeignFileRepos

const MediaWiki\MainConfigSchema::ForeignFileRepos

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

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

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

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

const MediaWiki\MainConfigSchema::ForeignUploadTargets

Initial value:

= [
        'default' => [ 'local', ],
        'type' => 'list',
    ]

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' ];

◆ FragmentMode

const MediaWiki\MainConfigSchema::FragmentMode

Initial value:

= [
        'default' => [ 'html5', 'legacy', ],
        'type' => 'list',
    ]

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

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

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

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

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

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

◆ GalleryOptions

const MediaWiki\MainConfigSchema::GalleryOptions

Initial value:

= [

Parameters for the "<gallery>" tag.

Fields are:

imagesPerRow: Default number of images per-row in the gallery. 0 -> Adapt to screensize
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.

◆ GenerateThumbnailOnParse

const MediaWiki\MainConfigSchema::GenerateThumbnailOnParse

Initial value:

= [
        'default' => true,
        'type' => 'boolean',
    ]

Render thumbnails while parsing wikitext.

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

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

$wgLocalFileRepo['transformVia404'] = true;

        ],
        'type' => 'map',
    ]

Map GIT repository URLs to viewer URLs to provide links in Special:Version.

Key is a pattern passed to preg_match() and preg_replace(), without the delimiters (which are #) and must match the whole URL. The value is the replacement for the key (it can contain $1, etc.) h will be replaced by the short SHA-1 (7 first chars) and H by the full SHA-1 of the HEAD revision. r will be replaced with a URL-encoded version of $1. R will be replaced with $1 and no URL-encoding

◆ GrantPermissions

const MediaWiki\MainConfigSchema::GrantPermissions

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.

= [
        'default' => [],
        'type' => 'map',
        'additionalProperties' => [ 'type' => 'string', ],
    ]

Groups that should inherit permissions from another group.

This allows defining a group that inherits its permissions from another group without having to copy all the permission grants over. For example, if you wanted a manual "confirmed" group that had the same permissions as "autoconfirmed":

$wgGroupInheritsPermissions['confirmed'] = 'autoconfirmed';

$wgGroupInheritsPermissions

Config variable stub for the GroupInheritsPermissions setting, for use by phpdoc and IDEs.

Definition config-vars.php:2711

Recursive inheritance is currently not supported. In the above example, confirmed will only gain the permissions explicitly granted (or revoked) from autoconfirmed, not any permissions that autoconfirmed might inherit.

Since: 1.38

Definition at line 7789 of file MainConfigSchema.php.

◆ GroupPermissions

const MediaWiki\MainConfigSchema::GroupPermissions

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 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!

◆ GroupsAddToSelf

const MediaWiki\MainConfigSchema::GroupsAddToSelf

Initial value:

    ]

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:

◆ HTCPRouting

const MediaWiki\MainConfigSchema::HTCPRouting

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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,
        ],
        '' => [
                '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:

$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' ],
        [ 'host' => '10.88.66.3', 'port' => '4827' ],

        'default' => '/usr/bin/convert',
    ]

The convert command shipped with ImageMagick.

◆ ImageMagickTempDir

const MediaWiki\MainConfigSchema::ImageMagickTempDir

Initial value:

= [
        'default' => false,
    ]

Temporary directory used for ImageMagick.

The directory must exist. Leave this set to false to let ImageMagick decide for itself.

Definition at line 1811 of file MainConfigSchema.php.

◆ ImagePreconnect

const MediaWiki\MainConfigSchema::ImagePreconnect

Initial value:

= [
        'default' => false,
    ]

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

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

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

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

◆ ImgAuthDetails

const MediaWiki\MainConfigSchema::ImgAuthDetails

Initial value:

= [
        'default' => false,
    ]

Set this to true if you use img_auth and want the user to see details on why access failed.

Definition at line 928 of file MainConfigSchema.php.

◆ ImgAuthPath

const MediaWiki\MainConfigSchema::ImgAuthPath

Initial value:

= [
        'default' => false,
    ]

The base path for img_auth.php.

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

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

Since: 1.35

Definition at line 565 of file MainConfigSchema.php.

◆ ImgAuthUrlPathMap

const MediaWiki\MainConfigSchema::ImgAuthUrlPathMap

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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

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

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

◆ ImplicitGroups

const MediaWiki\MainConfigSchema::ImplicitGroups

Initial value:

= [
        'default' => [ '*', 'user', 'autoconfirmed' ],
        'type' => 'list',
    ]

Implicit groups, aren't shown on Special:Listusers or somewhere else.

Definition at line 7798 of file MainConfigSchema.php.

◆ ImportSources

const MediaWiki\MainConfigSchema::ImportSources

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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.

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

If you have a very complex import sources setup, you can lazy-load it using the ImportSources hook.

If a user has the 'import' permission but not the 'importupload' permission, they will only be able to run imports through this transwiki interface.

Definition at line 10582 of file MainConfigSchema.php.

◆ ImportTargetNamespace

const MediaWiki\MainConfigSchema::ImportTargetNamespace

Initial value:

= [
        'default' => null,
    ]

Optional default target namespace for interwiki imports.

Can use this to create an incoming "transwiki"-style queue. Set to numeric key, not the name.

Users may override this in the Special:Import dialog.

Definition at line 10595 of file MainConfigSchema.php.

◆ InterlanguageLinkCodeMap

const MediaWiki\MainConfigSchema::InterlanguageLinkCodeMap

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Map of interlanguage link codes to language codes.

This is useful to override what is shown as the language name when the interwiki code does not match it exactly

Since: 1.35

Definition at line 4630 of file MainConfigSchema.php.

◆ InternalServer

const MediaWiki\MainConfigSchema::InternalServer

Initial value:

= [
        'default' => false,
    ]

Internal server name as known to CDN, if different.

Example:

$wgInternalServer = 'http://yourinternal.tld:8000';

$wgInternalServer

Config variable stub for the InternalServer setting, for use by phpdoc and IDEs.

◆ InterwikiCache

const MediaWiki\MainConfigSchema::InterwikiCache

Initial value:

= [
        'default' => false,
        'type' => 'false|map|string',
        'mergeStrategy' => 'replace',
    ]

Interwiki cache, either as an associative array or a path to a constant database (.cdb) file.

This data structure database is generated by the dumpInterwiki maintenance script (which lives in the WikimediaMaintenance repository) and has key formats such as the following:

dbname:key - a simple key (e.g. enwiki:meta)
_sitename:key - site-scope key (e.g. wiktionary:meta)
__global:key - global-scope key (e.g. __global:meta)
__sites:dbname - site mapping (e.g. __sites:enwiki)

Sites mapping just specifies site name, other keys provide "local url" data layout.

◆ InterwikiExpiry

const MediaWiki\MainConfigSchema::InterwikiExpiry

Initial value:

= [
        'default' => 10800,
    ]

Expiry time for cache of interwiki table.

Definition at line 6144 of file MainConfigSchema.php.

◆ InterwikiFallbackSite

const MediaWiki\MainConfigSchema::InterwikiFallbackSite

Initial value:

= [
        'default' => 'wiki',
    ]

Fallback site, if unable to resolve from cache.

Definition at line 6184 of file MainConfigSchema.php.

◆ InterwikiMagic

const MediaWiki\MainConfigSchema::InterwikiMagic

Initial value:

= [
        'default' => true,
    ]

Treat language links as magic connectors, not inline links.

Definition at line 4593 of file MainConfigSchema.php.

◆ InterwikiScopes

const MediaWiki\MainConfigSchema::InterwikiScopes

Initial value:

= [
        'default' => 3,
    ]

Specify number of domains to check for messages.

1: Just wiki(db)-level
2: wiki and global levels
3: site levels

Definition at line 6177 of file MainConfigSchema.php.

◆ InvalidateCacheOnLocalSettingsChange

const MediaWiki\MainConfigSchema::InvalidateCacheOnLocalSettingsChange

Initial value:

= [
        'default' => true,
    ]

Invalidate various caches when LocalSettings.php changes.

This is equivalent to setting $wgCacheEpoch to the modification time of LocalSettings.php, as was previously done in the default LocalSettings.php file.

On high-traffic wikis, this should be set to false, to avoid the need to check the file modification time, and to avoid the performance impact of unnecessary cache invalidations.

Definition at line 4255 of file MainConfigSchema.php.

◆ InvalidPasswordReset

const MediaWiki\MainConfigSchema::InvalidPasswordReset

Initial value:

= [
        'default' => true,
    ]

Specifies if users should be sent to a password-reset form on login, if their password doesn't meet the requirements of User::isValidPassword().

Since: 1.23

Definition at line 7044 of file MainConfigSchema.php.

◆ InvalidRedirectTargets

const MediaWiki\MainConfigSchema::InvalidRedirectTargets

Initial value:

= [
        'default' => [ 'Filepath', 'Mypage', 'Mytalk', 'Redirect' ],
        'type' => 'list',
    ]

Array of invalid page redirect targets.

Attempting to create a redirect to any of the pages in this array will make the redirect fail. Userlogout is hard-coded, so it does not need to be listed here. (T12569) Disallow Mypage and Mytalk as well.

As of now, this only checks special pages. Redirects to pages in other namespaces cannot be invalidated by this variable.

Definition at line 6098 of file MainConfigSchema.php.

◆ InvalidUsernameCharacters

const MediaWiki\MainConfigSchema::InvalidUsernameCharacters

Initial value:

= [
        'default' => '@:>',
    ]

Characters to prevent during new account creations.

This is used in a regular expression character class during registration (regex metacharacters like / are escaped).

◆ JobBackoffThrottling

const MediaWiki\MainConfigSchema::JobBackoffThrottling

Initial value:

= [
        'default' => [],
        'type' => 'map',
        'additionalProperties' => [ 'type' => 'float', ],
    ]

Map of job types to how many job "work items" should be run per second on each job runner process.

The meaning of "work items" varies per job, but typically would be something like "pages to update". A single job may have a variable number of work items, as is the case with batch jobs.

This is used by runJobs.php and not jobs run via $wgJobRunRate. These settings should be global to all wikis.

Definition at line 11055 of file MainConfigSchema.php.

◆ JobClasses

const MediaWiki\MainConfigSchema::JobClasses

Initial value:

= [
        'default' => [
            'deletePage' => DeletePageJob::class,
            'refreshLinks' => RefreshLinksJob::class,
            'deleteLinks' => DeleteLinksJob::class,
            'htmlCacheUpdate' => HTMLCacheUpdateJob::class,

            'AssembleUploadChunks' => AssembleUploadChunksJob::class,
            'PublishStashedFile' => PublishStashedFileJob::class,
            'ThumbnailRender' => ThumbnailRenderJob::class,
            'recentChangesUpdate' => RecentChangesUpdateJob::class,
            'refreshLinksPrioritized' => RefreshLinksJob::class,
            'refreshLinksDynamic' => RefreshLinksJob::class,

            'revertedTagUpdate' => RevertedTagUpdateJob::class,
            'enqueue' => EnqueueJob::class, 
            'null' => NullJob::class,
            'userEditCountInit' => UserEditCountInitJob::class,
        ],
        'type' => 'map',
    ]

Maps jobs to their handlers; extensions can add to this to provide custom jobs.

A job handler should either be a class name to be instantiated, or (since 1.30) a callback to use for creating the job object. The callback takes (Title, array map of parameters) as arguments.

Definition at line 10999 of file MainConfigSchema.php.

◆ JobQueueIncludeInMaxLagFactor

const MediaWiki\MainConfigSchema::JobQueueIncludeInMaxLagFactor

Initial value:

= [
        'default' => false,
    ]

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

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

Since: 1.29

Definition at line 11117 of file MainConfigSchema.php.

◆ JobRunRate

const MediaWiki\MainConfigSchema::JobRunRate

Initial value:

= [
        'default' => 1,
    ]

Number of jobs to perform per request.

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

Definition at line 12191 of file MainConfigSchema.php.

◆ JobSerialCommitThreshold

const MediaWiki\MainConfigSchema::JobSerialCommitThreshold

Initial value:

= [
        'default' => false,
        'type' => 'float|false',
    ]

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

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

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

Since: 1.26

Definition at line 11074 of file MainConfigSchema.php.

◆ JobTypeConf

const MediaWiki\MainConfigSchema::JobTypeConf

Initial value:

= [
        'default' => [
            'default' => [
                'class' => JobQueueDB::class,

            ],
        ],
        'type' => 'map',
    ]

Map of job types to configuration arrays.

This determines which queue class and storage system is used for each job type. Job types that do not have explicit configuration will use the 'default' config. These settings should be global to all wikis.

Definition at line 11086 of file MainConfigSchema.php.

◆ JobTypesExcludedFromDefaultQueue

const MediaWiki\MainConfigSchema::JobTypesExcludedFromDefaultQueue

Initial value:

= [
        'default' => [ 'AssembleUploadChunks', 'PublishStashedFile' ],
        'type' => 'list',
    ]

Jobs that must be explicitly requested, i.e.

aren't run by job runners unless special flags are set. The values here are keys of $wgJobClasses.

These can be:

Very long-running jobs.
Jobs that you would never want to run as part of a page rendering request.
Jobs that you want to run on specialized machines ( like transcoding, or a particular machine on your cluster has 'outside' web access you could restrict uploadFromUrl ) These settings should be global to all wikis.

◆ JpegPixelFormat

const MediaWiki\MainConfigSchema::JpegPixelFormat

Initial value:

= [
        'default' => 'yuv420',
    ]

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

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

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

This setting is currently supported only for the ImageMagick backend; others may default to 4:2:0 or 4:4:4 or maintaining the source file's sampling in the thumbnail.

Since: 1.27

Definition at line 1859 of file MainConfigSchema.php.

◆ JpegQuality

const MediaWiki\MainConfigSchema::JpegQuality

Initial value:

= [
        'default' => 80,
    ]

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

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

◆ LanguageCode

const MediaWiki\MainConfigSchema::LanguageCode

Initial value:

= [
        'default' => 'en',
    ]

Site language code.

See includes/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.

Definition at line 4570 of file MainConfigSchema.php.

◆ LanguageConverterCacheType

const MediaWiki\MainConfigSchema::LanguageConverterCacheType

Initial value:

= [
        'default' => CACHE_ANYTHING,

        ],
        'type' => 'map',
        'mergeStrategy' => 'replace',
    ]

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

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

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

◆ LegacyEncoding

const MediaWiki\MainConfigSchema::LegacyEncoding

Initial value:

= [
        'default' => false,
    ]

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

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

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

Definition at line 4700 of file MainConfigSchema.php.

◆ LegalTitleChars

const MediaWiki\MainConfigSchema::LegalTitleChars

Initial value:

= [
        'default' => ' %!"$&\'()*,\\-.\\/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.

        'items' => [ 'type' => 'string', ],
    ]

Other wikis on this site, can be administered from a single developer account.

List of wiki DB domain IDs; the format of each ID consist of 1-3 hyphen delimited alphanumeric components (each with no hyphens nor spaces) of any of the forms:

"<DB NAME>-<DB SCHEMA>-<TABLE PREFIX>"
"<DB NAME>-<TABLE PREFIX>"
"<DB NAME>" If hyphens appear in any of the components, then the domain ID parsing may not work in all cases and site functionality might be affected. If the schema ($wgDBmwschema) is left to the default "mediawiki" for all wikis, then the schema should be omitted from these IDs.

◆ LocalFileRepo

const MediaWiki\MainConfigSchema::LocalFileRepo

Initial value:

= [
        'default' => false,

        'dynamicDefault' => [ 'use' => [ 'UploadDirectory', 'ScriptPath', 'Favicon', 'UploadBaseUrl',
            'UploadPath', 'HashedUploadDirectory', 'ThumbnailScriptPath',
            'GenerateThumbnailOnParse', 'DeletedDirectory', 'UpdateCompatibleMetadata' ] ],
    ]

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.

Optional common properties:

backend A file backend name (see $wgFileBackends). If not specified, or if the name is not present in $wgFileBackends, an FSFileBackend will automatically be configured.
lockManager If a file backend is automatically configured, this will be lock manager name used. A lock manager named in $wgLockManagers, or one of the default lock managers "fsLockManager" or "nullLockManager". Default "fsLockManager".
favicon URL to a favicon. This is exposed via FileRepo::getInfo and ApiQueryFileRepoInfo. Originally for use by MediaViewer (T77093).

For most core repos:

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

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

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

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

             Default: 2.

deletedHashLevels Optional 'hashLevels' override for the 'deleted' zone.
thumbScriptUrl The URL for thumb.php (optional, not recommended)
transformVia404 Whether to skip media file transformation on parse and rely on a 404 handler instead.
thumbProxyUrl Optional. URL of where to proxy thumb.php requests to. This is also used internally for remote thumbnailing of upload stash files. Example: http://127.0.0.1:8888/wiki/dev/thumb/
thumbProxySecret Optional value of the X-Swift-Secret header to use in requests to thumbProxyUrl
disableLocalTransform If present and true, local image scaling will be disabled – it will throw an exception if attempted. thumbProxyUrl must be set for this to work, as well as either transformVia404 (preferred) or thumbScriptUrl.
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.
useJsonMetadata Whether handler metadata should be stored in JSON format. Default: true.
useSplitMetadata Whether handler metadata should be split up and stored in the text table. Default: false.
splitMetadataThreshold If the media handler opts in, large metadata items will be split into a separate blob in the database if the item is larger than this threshold. Default: 1000
updateCompatibleMetadata When true, image metadata will be upgraded by reloading it from the original file, if the handler indicates that it is out of date.

By default, when purging a file or otherwise refreshing file metadata, it is only reloaded when the metadata is invalid. Valid data originally loaded by a current or older compatible version is left unchanged. Enable this to also reload and upgrade metadata that was stored by an older compatible version. See also MediaHandler::isMetadataValid, and RefreshImageMetadata.

Default: false.
reserializeMetadata If true, image metadata will be automatically rewritten to the database if its serialization format is out of date. Default: false

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

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

ForeignDBRepo:

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

ForeignAPIRepo:

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

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

See also: FileRepo::__construct for the default options.; Setup.php for an example usage and default initialization.

◆ LocalHTTPProxy

const MediaWiki\MainConfigSchema::LocalHTTPProxy

Initial value:

= [
        'default' => false,
        'type' => 'string|false',
    ]

Reverse proxy to use for requests to domains in $wgLocalVirtualHosts.

When used, any port in the request URL will be dropped. The behavior of redirects and cookies is dependent upon the reverse proxy actually in use, as MediaWiki doesn't implement any special handling for them.

If set to false, no reverse proxy will be used for local requests.

Since: 1.38

◆ LocalInterwikis

const MediaWiki\MainConfigSchema::LocalInterwikis

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

Array for local interwiki values, for each of the interwiki prefixes that point to the current wiki.

Note, recent changes feeds use only the first entry in this array. See $wgRCFeeds.

Definition at line 6136 of file MainConfigSchema.php.

◆ LocalisationCacheConf

const MediaWiki\MainConfigSchema::LocalisationCacheConf

Initial value:

= [
        'properties' => [

            'manualRecache' => [ 'type' => 'bool', 'default' => false ],
        ],
        'type' => 'object',
    ]

Localisation cache configuration.

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

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

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

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

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

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

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

◆ LocalStylePath

const MediaWiki\MainConfigSchema::LocalStylePath

Initial value:

= [
        'default' => false,
        'dynamicDefault' => [ 'use' => [ 'ScriptPath' ] ]
    ]

The URL path of the skins directory.

Should not point to an external domain.

Defaults to "{$wgScriptPath}/skins".

Since: 1.17

Definition at line 440 of file MainConfigSchema.php.

◆ Localtimezone

const MediaWiki\MainConfigSchema::Localtimezone

Initial value:

= [
        'dynamicDefault' => true,
    ]

Fake out the timezone that the server thinks it's in.

This will be used for date display and not for what's stored in the DB. Leave to null to retain your server's OS-based timezone value.

This variable is currently used only for signature formatting and for local time/date parser variables ({{LOCALTIME}} etc.)

Timezones can be translated by editing MediaWiki messages of type timezone-nameinlowercase like timezone-utc.

A list of usable timezones can found at: https://www.php.net/manual/en/timezones.php

Examples:

$wgLocaltimezone = 'UTC';
$wgLocaltimezone = 'GMT';
$wgLocaltimezone = 'PST8PDT';
$wgLocaltimezone = 'Europe/Sweden';
$wgLocaltimezone = 'CET';

Definition at line 4884 of file MainConfigSchema.php.

◆ LocalTZoffset

const MediaWiki\MainConfigSchema::LocalTZoffset

Initial value:

= [
        'dynamicDefault' => [ 'use' => [ 'Localtimezone' ] ]
    ]

Set an offset from UTC in minutes to use for the default timezone setting for anonymous users and new user accounts.

This setting is used for most date/time displays in the software, and is overridable in user preferences. It is not used for signature timestamps.

By default, this will be set to match $wgLocaltimezone.

Definition at line 4910 of file MainConfigSchema.php.

◆ LocalVirtualHosts

const MediaWiki\MainConfigSchema::LocalVirtualHosts

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Local virtual hosts.

This lists domains that are configured as virtual hosts on the same machine. It is expected that each domain can be identified by its hostname alone, without any ports.

This affects the following:

MWHttpRequest: If a request is to be made to a domain listed here, or any subdomain thereof, then $wgLocalHTTPProxy will be used. Command-line scripts are not affected by this setting and will always use the proxy if it is configured.

Since: 1.25

◆ LockManagers

const MediaWiki\MainConfigSchema::LockManagers

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

List of lock manager backend configurations.

Each backend configuration has the following parameters:

name : A unique name for the lock manager
class : The lock manager class to use

See LockManager::__construct() for more details. Additional parameters are specific to the lock manager class used. These settings should be global to all wikis.

Definition at line 1382 of file MainConfigSchema.php.

◆ LogActions

const MediaWiki\MainConfigSchema::LogActions

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Maps log actions to message keys, for formatting log entries of each type and action when displaying logs to the user.

        ],
        'type' => 'map',
    ]

Lists the message key string for descriptive text to be shown at the top of each log type.

Extensions with custom log types may add to this array.

Since: 1.19, if you follow the naming convention log-description-TYPE, where TYPE is your log type, yoy don't need to use this array.

Definition at line 11343 of file MainConfigSchema.php.

◆ LoginLanguageSelector

const MediaWiki\MainConfigSchema::LoginLanguageSelector

Initial value:

= [
        'default' => false,
    ]

Show a bar of language selection links in the user login and user registration forms; edit the "loginlanguagelinks" message to customise these.

Definition at line 4807 of file MainConfigSchema.php.

◆ LogNames

const MediaWiki\MainConfigSchema::LogNames

Initial value:

= [
        'default' => [
            '' => 'all-logs-page',

        ],
        'type' => 'map',
    ]

Lists the message key string for each log type.

The localized messages will be listed in the user interface.

Extensions with custom log types may add to this array.

Since: 1.19, if you follow the naming convention log-name-TYPE, where TYPE is your log type, you don't need to use this array.

◆ Logo

const MediaWiki\MainConfigSchema::Logo

Initial value:

= [
        'default' => false,
        'dynamicDefault' => [ 'use' => [ 'ResourceBasePath' ] ]
    ]

The URL path of the wiki logo.

The logo size should be 135x135 pixels.

Defaults to "$wgResourceBasePath/resources/assets/change-your-logo.svg". Developers should retrieve this logo (and other variants) using the static function MediaWiki\ResourceLoader\SkinModule::getAvailableLogos Ignored if $wgLogos is set.

Definition at line 621 of file MainConfigSchema.php.

◆ LogoHD

const MediaWiki\MainConfigSchema::LogoHD

Initial value:

= [
        'default' => false,

        'deprecated' => 'since 1.35. Developers should retrieve this logo (and other variants) ' .
            'using the static function MediaWiki\ResourceLoader\SkinModule::getAvailableLogos. $wgLogos ' .
            'should be used instead.',
    ]

Array with URL paths to HD versions of the wiki logo.

The scaled logo size should be under 135x155 pixels. Only 1.5x and 2x versions are supported.

Example:: $wgLogoHD = [

"1.5x" => "path/to/1.5x_version.png",

"2x" => "path/to/2x_version.png"

];

$wgLogoHD
$wgLogoHD
Config variable stub for the LogoHD setting, for use by phpdoc and IDEs.
Definition config-vars.php:178

SVG is also supported but when enabled, it disables 1.5x and 2x as svg will already be optimised for screen resolution.

Example:: $wgLogoHD = [

"svg" => "path/to/svg_version.svg",

];

Since: 1.25

Deprecated: since 1.35. Developers should retrieve this logo (and other variants) using the static function MediaWiki\ResourceLoader\SkinModule::getAvailableLogos. $wgLogos should be used instead.

◆ Logos

const MediaWiki\MainConfigSchema::Logos

Initial value:

= [
        'default' => false,
        'type' => 'map|false',
    ]

Specification for different versions of the wiki logo.

This is an array which should have the following k/v pairs: All path values can be either absolute or relative URIs

The 1x key is a path to the 1x version of square logo (should be 135x135 pixels) The 1.5x key is a path to the 1.5x version of square logo The 2x key is a path to the 2x version of square logo The svg key is a path to the svg version of square logo The icon key is a path to the version of the logo without wordmark and tagline The wordmark key may be null or an array with the following fields

src path to wordmark version
1x path to svg wordmark version (if you want to support browsers with SVG support with an SVG logo)
width width of the logo in pixels
height height of the logo in pixels The tagline key may be null or array with the following fields
src path to tagline image
width width of the tagline in pixels
height height of the tagline in pixels

Example:: $wgLogos = [

'1x' => 'path/to/1x_version.png',

'1.5x' => 'path/to/1.5x_version.png',

◆ LogRestrictions

const MediaWiki\MainConfigSchema::LogRestrictions

Initial value:

= [
        'default' => [ 'suppress' => 'suppressionlog', ],
        'type' => 'map',
    ]

This restricts log access to those who have a certain right Users without this will not see it in the option menu and can not view it Restricted logs are not added to recent changes Logs should remain non-transcludable Format: logtype => permissiontype.

Definition at line 11276 of file MainConfigSchema.php.

◆ LogTypes

const MediaWiki\MainConfigSchema::LogTypes

Initial value:

= [
        'default' => [
            '',
            'block',
            'protect',
            'rights',
            'delete',
            'upload',
            'move',
            'import',
            'patrol',
            'merge',
            'suppress',
            'tag',

            'contentmodel',
        ],
        'type' => 'list',
    ]

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

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

◆ MainCacheType

const MediaWiki\MainConfigSchema::MainCacheType

Initial value:

= [
        'default' => CACHE_NONE,
    ]

Main cache type.

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

The options are:

CACHE_ANYTHING: Use anything, as long as it works
CACHE_NONE: Do not cache
CACHE_DB: Store cache objects in the DB
CACHE_MEMCACHED: MemCached, must specify servers in $wgMemCachedServers
CACHE_ACCEL: APC, APCU or WinCache
(other): A string may be used which identifies a cache configuration in $wgObjectCaches.

See also: $wgMessageCacheType, $wgParserCacheType

◆ MainPageIsDomainRoot

const MediaWiki\MainConfigSchema::MainPageIsDomainRoot

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Option to whether serve the main page as the domain root.

Warning: EXPERIMENTAL!

Since: 1.34

Definition at line 845 of file MainConfigSchema.php.

◆ MainStash

const MediaWiki\MainConfigSchema::MainStash

Initial value:

= [
        'default' => 'db-replicated',
    ]

The object store type of the main stash.

This should be a fast storage system optimized for lightweight data, both ephemeral and permanent, for things like counters, tokens, and blobs. The dataset access scope should include all the application servers in all datacenters. Thus, the data must be replicated among all datacenters. The store should have "Last Write Wins" eventual consistency. Per https://en.wikipedia.org/wiki/PACELC_theorem, the store should act as a PA/EL distributed system for these operations.

The multi-datacenter strategy for MediaWiki is to have CDN route HTTP POST requests to the primary datacenter and HTTP GET/HEAD/OPTIONS requests to the closest datacenter to the client. The stash accepts write operations from any datacenter, but cross-datacenter replication is asynchronous.

Modules that use the main stash can expect race conditions to occur if a key can receive write operations originating from multiple datacenters. To improve consistency, callers should avoid main stash updates during non-POST requests. In any case, callers should gracefully tolerate occasional key evictions, temporary inconsistencies among datacenters, and violations of linearizability (e.g. during timeouts). Modules that can never handle these kind of anamolies should use other storage mediums.

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

◆ MainWANCache

const MediaWiki\MainConfigSchema::MainWANCache

Initial value:

= [
        'default' => false,
        'type' => 'integer|string|false',
    ]

Main Wide-Area-Network cache type.

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

For single server or single datacenter setup, setting $wgMainCacheType is enough.

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

The options are:

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

◆ MangleFlashPolicy

const MediaWiki\MainConfigSchema::MangleFlashPolicy

Initial value:

= [
        'default' => true,
        'deprecated' => 'since 1.39; no longer has any effect',
    ]

Formerly a workaround for a security vulnerability caused by installation of Flash as a browser extension.

Since: 1.25

Deprecated: since 1.39

Definition at line 5267 of file MainConfigSchema.php.

◆ ManualRevertSearchRadius

const MediaWiki\MainConfigSchema::ManualRevertSearchRadius

Initial value:

= [
        'default' => 15,
        'type' => 'integer',
    ]

Maximum number of revisions of a page that will be checked against every new edit made to determine whether the edit was a manual revert.

Computational time required increases roughly linearly with this configuration variable.

Larger values will let you detect very deep reverts, but at the same time can give unexpected results (such as marking large amounts of edits as reverts) and may slow down the wiki slightly when saving new edits.

Setting this to 0 will disable the manual revert detection feature entirely.

See this document for a discussion on this topic: https://meta.wikimedia.org/wiki/Research:Revert

Since: 1.36

◆ MaxAnimatedGifArea

const MediaWiki\MainConfigSchema::MaxAnimatedGifArea

Initial value:

= [
        'default' => 12500000,
    ]

Force thumbnailing of animated GIFs above this size to a single frame instead of an animated thumbnail.

As of MW 1.17 this limit is checked against the total size of all frames in the animation.

It probably makes sense to keep this equal to $wgMaxImageArea.

Definition at line 1987 of file MainConfigSchema.php.

◆ MaxArticleSize

const MediaWiki\MainConfigSchema::MaxArticleSize

Initial value:

= [
        'default' => 2048,
    ]

Maximum article size in kibibytes.

Definition at line 3520 of file MainConfigSchema.php.

◆ MaxCredits

const MediaWiki\MainConfigSchema::MaxCredits

Initial value:

= [
        'default' => 0,
    ]

Set this to the number of authors that you want to be credited below an article text.

Set it to zero to hide the attribution block, and a negative number (like -1) to show all authors. Note that this will require 2-3 extra database hits, which can have a not insignificant impact on performance for large wikis.

Definition at line 10540 of file MainConfigSchema.php.

◆ MaxExecutionTimeForExpensiveQueries

const MediaWiki\MainConfigSchema::MaxExecutionTimeForExpensiveQueries

Initial value:

= [
        'default' => 0,
    ]

Max execution time for queries of several expensive special pages such as RecentChanges in milliseconds.

Since: 1.38

Definition at line 3199 of file MainConfigSchema.php.

◆ MaxImageArea

const MediaWiki\MainConfigSchema::MaxImageArea

Initial value:

= [
        'default' => 12500000,
        'type' => 'string|integer|false',
    ]

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

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

If set to false, MediaWiki will not check the size of the image before attempting to scale it. Extensions may still override this setting by using the BitmapHandlerCheckImageArea hook.

The default is 50 MB if decompressed to RGBA form, which corresponds to 12.5 million pixels or 3500x3500.

Definition at line 1974 of file MainConfigSchema.php.

◆ MaximalPasswordLength

const MediaWiki\MainConfigSchema::MaximalPasswordLength

Initial value:

= [
        'default' => false,
        'deprecated' => 'since 1.26, use $wgPasswordPolicy\'s MaximalPasswordLength.',
    ]

Specifies the maximal length of a user password (T64685).

It is not recommended to make this greater than the default, as it can allow DoS attacks by users setting really long passwords. In addition, this should not be lowered too much, as it enforces weak passwords.

Warning: Unlike other password settings, user with passwords greater than the maximum will not be able to log in.

Deprecated: since 1.26, use $wgPasswordPolicy's MaximalPasswordLength.

Definition at line 7033 of file MainConfigSchema.php.

◆ MaximumMovedPages

    ]

Robot policies per namespaces.

The default policy is given above, the array is made of namespace constants as defined in includes/Defines.php. You can- not specify a different default policy for NS_SPECIAL: it is always noindex, nofollow. This is because a number of special pages (e.g., ListPages) have many permutations of options that display the same data under redundant URLs, so search engine spiders risk getting lost in a maze of twisty special pages, all alike, and never reaching your actual content.

Example:

$wgNamespaceRobotPolicies = [ NS_TALK => 'noindex' ];

    ]

If this is set to an array of domains, external links to these domain names (or any subdomains) will not be set to rel="nofollow" regardless of the value of $wgNoFollowLinks.

For instance:

$wgNoFollowDomainExceptions = [ 'en.wikipedia.org', 'wiktionary.org', 'mediawiki.org' ];

This would add rel="nofollow" to links to de.wikipedia.org, but not en.wikipedia.org, wiktionary.org, en.wiktionary.org, us.en.wikipedia.org, etc.

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Pages in namespaces in this array can not be used as templates.

Elements MUST be numeric namespace ids, you can safely use the MediaWiki namespaces constants (NS_USER, NS_MAIN...).

◆ ObjectCaches

const MediaWiki\MainConfigSchema::ObjectCaches

Advanced object cache configuration.

Use this to define the class names and constructor parameters which are used for the various cache types. Custom cache types may be defined here and referenced from $wgMainCacheType, $wgMessageCacheType, $wgParserCacheType, or $wgLanguageConverterCacheType.

The format is an associative array where the key is a cache identifier, and the value is an associative array of parameters. One of the following parameters specifying the class must be given:

class: The class name which will be used.
factory: A callable function which will generate a suitable cache object.

The following parameters are shared and understood by most classes:

loggroup: The log channel to use.

For SqlBagOStuff, the main configured database will be used, unless one of the following three parameters is given:

server: Server config map for Database::factory() that describes the database to use for all key operations in the current region. This is overridden by "servers".
servers: Map of tag strings to server config maps, each for Database::factory(), describing the set of database servers on which to distribute key operations in the current region. Data is distributed among the servers via key hashing based on the server tags. Therefore, each tag represents a shard of the dataset. Tags are useful for failover using cold-standby servers and for managing shards with replica servers in multiple regions (each having different hostnames).
cluster: The ExternalStore cluster name to use.

SqlBagOStuff also accepts the following optional parameters:

dbDomain: The database name to pass to the LoadBalancer.
multiPrimaryMode: Whether the portion of the dataset belonging to each tag/shard is replicated among one or more regions, with one "co-primary" server in each region. Queries are issued in a manner that provides Last-Write-Wins eventual consistency. This option requires the "server" or "servers" options. Only MySQL, with statement based replication (log_bin='ON' and binlog_format='STATEMENT') is supported. Also, the modtoken column must exist on the objectcache table(s).
purgePeriod: The average number of object cache writes in between garbage collection operations, where expired entries are removed from the database. Or in other words, the probability of performing a purge is one in every this number. If set to zero, purging will never be done at runtime (for use with PurgeParserCache).
purgeLimit: Maximum number of rows to purge at once.
tableName: The table name to use, default is "objectcache".
shards: The number of tables to use for data storage on each server. If greater than 1, table names are formed in the style objectcacheNNN where NNN is the shard index, between 0 and shards-1. The number of digits used in the suffix is the minimum number required to hold the largest shard index. Data is distributed among the tables via key hashing. This helps mitigate MySQL bugs 61735 and 61736.
replicaOnly: Whether to only use replica servers and only support read operations. This option requires the use of LoadBalancer and should only be used by ReplicatedBagOStuff.
writeBatchSize: Default maximum number of rows to change in each query for write operations that can be chunked into a set of smaller writes.

◆ ParsoidCacheConfig

const MediaWiki\MainConfigSchema::ParsoidCacheConfig

Initial value:

            'WarmParsoidParserCache' => [ 'type' => 'bool', 'default' => false ],
        ]
    ]

Configuration for the caching related to parsoid output.

The configuration contains the following keys:

StashType: The type of object store to be used by the ParsoidOutputStash service, which stores the base state of HTML based edits. Valid options are the keys of $wgObjectCaches, e.g. CACHE_* constants. Per default, the value of the MainStash setting will be used. This should be an object store that provides fairly solid persistence guarantees, since losing an entry from the stash may mean that the user can't save their edit. If null, the value of the MainStash configuration setting will be used.
StashDuration: The number of seconds for which an entry in the stash should be kept. Should be long enough for users to finish editing, since losing an entry from the stash may mean that the user can't save their edit. This is set to one day per default.
CacheThresholdTime: If parsing is completed before this time (in seconds), assume it's a small page that is fast for parsing and does not need caching. Setting this to zero causes all outputs to be cached.
WarmParsoidParserCache: Setting this to true will pre-populate the parsoid parser cache with parsoid outputs on page edits. This speeds up loading HTML into Visual Editor.

Since: 1.39

Stability: unstable: Per MediaWiki 1.39, the structure of this configuration is still subject to change.

        ],
        'type' => 'list',
    ]

Limit password attempts to X attempts per Y seconds per IP per account.

Value is an array of arrays. Each sub-array must have a key for count (ie count of how many attempts before throttle) and a key for seconds. If the key 'allIPs' (case sensitive) is present, then the limit is just per account instead of per IP per account.

Since: 1.27 allIps support and multiple limits added in 1.27. Prior to 1.27 this only supported having a single throttle.

◆ PasswordExpireGrace

const MediaWiki\MainConfigSchema::PasswordExpireGrace

Initial value:

Definition at line 2619 of file MainConfigSchema.php.

◆ PasswordPolicy

const MediaWiki\MainConfigSchema::PasswordPolicy

Password policy for the wiki.

Structured as

[
    'policies' => [ <group> => [ <policy> => <settings>, ... ], ... ],
    'checks' => [ <policy> => <callback>, ... ],
]

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

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

], simply

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

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

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

The checks supported by core are:

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

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

◆ RateLimits

const MediaWiki\MainConfigSchema::RateLimits

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.

$wgRateLimits = [
    'edit' => [
        'anon' => [ x, y ], // any and all anonymous edits (aggregate)
        'user' => [ x, y ], // each logged-in user

];

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.

$wgRateLimits = [
    'some-action' => [
        '&can-bypass' => false,

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Configuration for feeds to which notifications about recent changes will be sent.

The following feed classes are available by default:

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

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

Common options:

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

FormattedRCFeed-specific options:

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

IRCColourfulRCFeedFormatter-specific options:

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

JSONRCFeedFormatter-specific options:

'channel' – if set, the 'channel' parameter is also set in JSON values.

Examples:

$wgRCFeeds['example'] = [
    'uri' => 'udp://localhost:1336',
    'formatter' => 'JSONRCFeedFormatter',
    'add_interwiki_prefix' => false,
    'omit_bots' => true,

= [
        'default' => false,
    ]

Filter $wgRCLinkDays by $wgRCMaxAge to avoid showing links for numbers higher than what will be stored.

◆ ReadOnly

const MediaWiki\MainConfigSchema::ReadOnly

Initial value:

= [
        'default' => null,
    ]

◆ ReadOnlyFile

const MediaWiki\MainConfigSchema::ReadOnlyFile

Initial value:

= [
        'default' => false,

        'type' => 'map',
        'additionalProperties' => [ 'type' => 'integer', ],
    ]

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.

  // message for the tooltip of the letter
  'title' => 'tooltip-msg',
  // optional (defaults to 'tooltip-msg'), message to use in the legend box
  'legend' => 'legend-msg',
  // optional (defaults to 'flag'), CSS class to put on changes lists rows
  'class' => 'css-class',
  // optional (defaults to 'any'), how top-level flag is determined.  'any'
  // will set the top-level flag if any line contains the flag, 'all' will
  // only be set if all lines contain the flag.

◆ RedirectSources

const MediaWiki\MainConfigSchema::RedirectSources

Initial value:

= [
        'default' => false,
    ]

If local interwikis are set up which allow redirects, set this regexp to restrict URLs which will be displayed as 'redirected from' links.

Example: It might look something like this:

$wgRedirectSources = '!^https?://[a-z-]+\\.wikipedia\\.org/!';

$wgRedirectSources

Config variable stub for the RedirectSources setting, for use by phpdoc and IDEs.

Definition config-vars.php:2234

Leave at false to avoid displaying any incoming redirect markers. This does not affect intra-wiki redirects, which don't change the URL.

Definition at line 6204 of file MainConfigSchema.php.

◆ ReferrerPolicy

const MediaWiki\MainConfigSchema::ReferrerPolicy

Initial value:

= [
        'default' => false,
        'type' => 'list|string|false',
    ]

Value for the referrer policy meta tag.

One or more of the values defined in the Referrer Policy specification: https://w3c.github.io/webappsec-referrer-policy/ ('no-referrer', 'no-referrer-when-downgrade', 'same-origin', 'origin', 'strict-origin', 'origin-when-cross-origin', 'strict-origin-when-cross-origin', or 'unsafe-url') Setting it to false prevents the meta tag from being output (which results in falling back to the Referrer-Policy header, or 'no-referrer-when-downgrade' if that's not set either.) Setting it to an array (supported since 1.31) will create a meta tag for each value, in the reverse of the order (meaning that the first array element will be the default and the others used as fallbacks for browsers which do not understand it).

◆ ResourceLoaderSources

const MediaWiki\MainConfigSchema::ResourceLoaderSources

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Extensions should register foreign module sources here.

'local' is a built-in source that is not in this array, but defined by ResourceLoader::__construct() so that it cannot be unset.

Example:

$wgResourceLoaderSources['foo'] = 'http://example.org/w/load.php';

$wgResourceLoaderSources

Config variable stub for the ResourceLoaderSources setting, for use by phpdoc and IDEs.

Definition config-vars.php:2036

Definition at line 5707 of file MainConfigSchema.php.

◆ ResourceLoaderStorageEnabled

const MediaWiki\MainConfigSchema::ResourceLoaderStorageEnabled

Initial value:

= [
        'default' => true,
    ]

Whether ResourceLoader should attempt to persist modules in localStorage on browsers that support the Web Storage API.

Definition at line 5810 of file MainConfigSchema.php.

◆ ResourceLoaderStorageVersion

const MediaWiki\MainConfigSchema::ResourceLoaderStorageVersion

Initial value:

= [
        'default' => 1,
    ]

Cache version for client-side ResourceLoader module storage.

You can trigger invalidation of the contents of the module store by incrementing this value.

Since: 1.23

Definition at line 5820 of file MainConfigSchema.php.

◆ ResourceLoaderUseObjectCacheForDeps

const MediaWiki\MainConfigSchema::ResourceLoaderUseObjectCacheForDeps

Initial value:

= [
        'default' => false,
    ]

Use the main stash instead of the module_deps table for indirect dependency tracking.

Since: 1.35

Warning: EXPERIMENTAL

Definition at line 5753 of file MainConfigSchema.php.

◆ ResourceLoaderValidateJS

const MediaWiki\MainConfigSchema::ResourceLoaderValidateJS

Initial value:

= [
        'default' => 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 5790 of file MainConfigSchema.php.

◆ ResourceModules

const MediaWiki\MainConfigSchema::ResourceModules

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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

Note: It is recommended to define modules using the ResourceModule attribute in extension.json or skin.json when possible (instead of via PHP global variables).

Registration is internally handled by ResourceLoader::register.

Available modules

Modules that ship with MediaWiki core are registered via resources/Resources.php. For a full list with documentation, see: ResourceLoader/Core_modules.

Options

class {string}: By default a module is assumed to bundle file resources as handled by the MediaWiki\ResourceLoader\FileModule class. Use this option to use a different implementation of MediaWiki\ResourceLoader\Module instead.

Default: \\MediaWiki\\ResourceLoader\\FileModule
factory {string}: Override the instantiation of the MediaWiki\ResourceLoader\Module class using a PHP callback. This allows dependency injection to be used. This option cannot be combined with the class option.

Since: MW 1.30
dependencies {string[]|string}: Modules that must be executed before this module. Module name string or list of module name strings.

Default: []
deprecated {boolean|string}: Whether the module is deprecated and usage is discouraged. Set to boolean true, or a string to include in the warning message.

Default: false
group {string}: Optional request group to override which modules may be downloaded together in an HTTP batch request. By default, any two modules may be loaded together in the same batch request. Set this option to a descriptive string to give the module its own HTTP request. To allow other modules to join this new request, give those the same request group.

Use this option with caution. The default behaviour is well-tuned already, and setting this often does more harm than good. For more about request balancing optimisations, see ResourceLoader/Architecture#Balance.
skipFunction {string}: Allow this module to be satisfied as dependency without actually loading or executing scripts from the server, if the specified JavaScript function returns true.

Use this to provide polyfills that are natively available in newer browsers. Specify the relative path to a JavaScript file containing a top-level return statement. The contents of the file should not contain any wrapping function, it will be wrapped by ResourceLoader in an anonymous function and invoked when the module is considered for loading.
targets {string[]} List of ResourceLoader targets where the module may be loaded from. This is used by the MobileFrontend extension to prevent certain modules from being loaded.

This option is deprecated. See T127268.

Default: ["desktop"]

FileModule options

localBasePath {string}: Base file path to prepend to relative file paths specified in other options.

Default: $IP
remoteBasePath {string}: Base URL path to prepend to relative file paths specified in other options. This is used to form URLs for files, such as when referencing images in stylesheets, or in debug mode to serve JavaScript files directly.

Default: $wgResourceBasePath (which defaults to $wgScriptPath)
remoteExtPath {string}: Shortcut for remoteBasePath that is relative to $wgExtensionAssetsPath. Use this when defining modules from an extension, so as to avoid hardcoding the script path of the MediaWiki install or the location of the extensions directory.

This option is mutually exclusive with remoteBasePath.
styles {string[]|string|array<string,array>}: Styles to always include in the module. File path or list of file paths, relative to localBasePath. The stylesheet can be automatically wrapped in a @media query by specifying the file path as the key in an object (instead of the value), with the value specifying a media query.

See Stylesheet examples below.

See also $wgResourceModuleSkinStyles.

Extended options:
- skinStyles {string[]|string}: Styles to include in specific skin contexts. Array keyed is by skin name with file path or list of file paths as value, relative to localBasePath.
Default: []
noflip {boolean}: By default, CSSJanus will be used automatically to perform LTR-to-RTL flipping when loaded in a right-to-left (RTL) interface language context. Use this option to skip CSSJanus LTR-to-RTL flipping for this module, for example when registering an external library that already handles RTL styles.

Default: false
packageFiles {string[]|array[]} Specify script files and (virtual) data files to include in the module. Each internal JavaScript file retains its own local module scope and its private exports can be accessed separately by other client-side code in the same module, via the local require() function.

Modules that use package files should export any public API methods using module.exports.

See examples at ResourceLoader/Package_files on mediawiki.org.

The packageFiles feature cannot be combined with legacy scripts that use the scripts option, including its extended variants languageScripts, skinScripts, and debugScripts.

Since: MW 1.33

Default: []
scripts {string[]|string}: Scripts to always include in the module. File path or list of file paths, relative to localBasePath.

These files are concatenated blindly and executed as a single client-side script. Modules using this option are sometimes referred to as "legacy scripts" to distinguish them from those that use the packageFiles option.

Modules that use legacy scripts usually attach any public APIs they have to the mw global variable. If a module contains just one file, it is also supported to use the newer module.exports mechanism, though if the module contains more than one legacy script, it is considered unsafe and unsupported to use this mechanism (use packageFiles instead). See also Coding conventions/JavaScript.

Default: []

Extended options, concatenated in this order:
- languageScripts {string[]|string}: Scripts to include in specific language contexts. Array is keyed by language code with file path or list of file path.
- skinScripts {string[]|string}: Scripts to include in specific skin contexts. Array keyed is by skin name with file path or list of file paths.
- debugScripts {string[]|string}: Scripts to include in debug contexts. File path or list of file paths.
messages {string[]} Localisation messages to bundle with this module, for client-side use via mw.msg() and mw.message(). List of message keys.

Default: []
templates {string[]} List of template files to be loaded for client-side usage via mw.templates.

Default: []
es6 {boolean}: If true, this module will only be executed in browsers that support ES6. You should set this flag for modules that use ES6 in their JavaScript. Only use this for modules that provide progressive enhancements that are safe to not load in browsers that are not modern but still have a substantial user base, like IE11.

Since: MW 1.36

Default: false

◆ ResourceModuleSkinStyles

const MediaWiki\MainConfigSchema::ResourceModuleSkinStyles

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Add extra skin-specific styles to a resource module.

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

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

Example:

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

This is effectively equivalent to:

Equivalent:

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

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

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

Example:

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

This is effectively equivalent to:

Equivalent:

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

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

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

Example:

$wgResourceModuleSkinStyles['foo'] = [
  'bar' => 'bar.css',
  'quux' => 'quux.css',
  'remoteSkinPath' => 'Foo',
  'localBasePath' => __DIR__,
];

◆ ResponsiveImages

const MediaWiki\MainConfigSchema::ResponsiveImages

Initial value:

= [
        'default' => 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.

Definition at line 2421 of file MainConfigSchema.php.

◆ RestAllowCrossOriginCookieAuth

const MediaWiki\MainConfigSchema::RestAllowCrossOriginCookieAuth

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Allows authenticated cross-origin requests to the REST API with session cookies.

With this option enabled, any origin specified in $wgCrossSiteAJAXdomains may send session cookies for authorization in the REST API.

There is a performance impact by enabling this option. Therefore, it should be left disabled for most wikis and clients should instead use OAuth to make cross-origin authenticated requests.

◆ RestPath

const MediaWiki\MainConfigSchema::RestPath

Initial value:

= [
        'default' => false,
        'dynamicDefault' => [ 'use' => [ 'ScriptPath' ] ]
    ]

The URL path to the REST API Defaults to "{$wgScriptPath}/rest.php".

Since: 1.34

Definition at line 400 of file MainConfigSchema.php.

◆ RestrictDisplayTitle

const MediaWiki\MainConfigSchema::RestrictDisplayTitle

Initial value:

= [
        'default' => true,
    ]

For consistency, restrict DISPLAYTITLE to text that normalizes to the same canonical DB key.

Also disallow some inline CSS rules like display: none; which can cause the text to be hidden or unselectable.

Definition at line 6485 of file MainConfigSchema.php.

◆ RestrictionLevels

const MediaWiki\MainConfigSchema::RestrictionLevels

Initial value:

= [
        'default' => [ '', 'autoconfirmed', 'sysop' ],
        'type' => 'list',
    ]

Rights which can be required for each protection level (via action=protect)

You can add a new protection level that requires a specific permission by manipulating this array. The ordering of elements dictates the order on the protection form's lists.

'' will be ignored (i.e. unprotected)
'autoconfirmed' is quietly rewritten to 'editsemiprotected' for backwards compatibility
'sysop' is quietly rewritten to 'editprotected' for backwards compatibility

Definition at line 7864 of file MainConfigSchema.php.

◆ RestrictionTypes

const MediaWiki\MainConfigSchema::RestrictionTypes

Initial value:

= [
        'default' => [ 'create', 'edit', 'move', 'upload' ],
        'type' => 'list',
    ]

Set of available actions that can be restricted via action=protect You probably shouldn't change this.

Translated through restriction-* messages. Title::getRestrictionTypes() will remove restrictions that are not applicable to a specific title (create and upload)

Definition at line 7848 of file MainConfigSchema.php.

◆ RevertedTagMaxDepth

const MediaWiki\MainConfigSchema::RevertedTagMaxDepth

Initial value:

= [
        'default' => 15,
        'type' => 'integer',
    ]

Maximum depth (revision count) of reverts that will have their reverted edits marked with the mw-reverted change tag.

Reverts deeper than that will not have any edits marked as reverted at all.

Large values can lead to lots of revisions being marked as "reverted", which may appear confusing to users.

Setting this to 0 will disable the reverted tag entirely.

Since: 1.36

Definition at line 6652 of file MainConfigSchema.php.

◆ RevisionCacheExpiry

const MediaWiki\MainConfigSchema::RevisionCacheExpiry

Initial value:

= [
        'default' => 86400 * 7,
        'type' => 'integer',
    ]

Revision text may be cached in the main WAN cache to reduce load on external storage servers and object extraction overhead for frequently-loaded revisions.

Set to 0 to disable, or number of seconds before cache expiry.

Definition at line 3382 of file MainConfigSchema.php.

◆ RevokePermissions

const MediaWiki\MainConfigSchema::RevokePermissions

Initial value:

= [
        'default' => [],
        'type' => 'map',
        'mergeStrategy' => 'array_plus_2d',
    ]

Permission keys revoked from users in each group.

This acts the same way as $wgGroupPermissions above, except that if the user is in a group here, the permission will be removed from them.

Improperly setting this could mean that your users will be unable to perform certain essential tasks, so use at your own risk!

Definition at line 7764 of file MainConfigSchema.php.

◆ RightsIcon

const MediaWiki\MainConfigSchema::RightsIcon

Initial value:

= [
        'default' => null,
    ]

Override for copyright metadata.

Definition at line 10522 of file MainConfigSchema.php.

◆ RightsPage

const MediaWiki\MainConfigSchema::RightsPage

Initial value:

= [
        'default' => null,
    ]

Override for copyright metadata.

This is the name of the page containing information about the wiki's copyright status, which will be added as a link in the footer if it is specified. It overrides $wgRightsUrl if both are specified.

Definition at line 10493 of file MainConfigSchema.php.

◆ RightsText

const MediaWiki\MainConfigSchema::RightsText

Initial value:

= [
        'default' => null,
    ]

If either $wgRightsUrl or $wgRightsPage is specified then this variable gives the text for the link.

Otherwise, it will be treated as raw HTML.

If using $wgRightsUrl then this value must be specified. If using $wgRightsPage then the name of the page will also be used as the link text if this variable is not set.

Definition at line 10515 of file MainConfigSchema.php.

◆ RightsUrl

const MediaWiki\MainConfigSchema::RightsUrl

Initial value:

= [
        'default' => null,
    ]

Set this to specify an external URL containing details about the content license used on your wiki.

If $wgRightsPage is set then this setting is ignored.

Definition at line 10503 of file MainConfigSchema.php.

◆ RunJobsAsync

const MediaWiki\MainConfigSchema::RunJobsAsync

Initial value:

= [
        'default' => false,
    ]

When $wgJobRunRate > 0, try to run jobs asynchronously, spawning a new process to handle the job execution, instead of blocking the request until the job execution finishes.

Since: 1.23

Definition at line 12202 of file MainConfigSchema.php.

◆ Script

const MediaWiki\MainConfigSchema::Script

Initial value:

= [
        'default' => false,
        'dynamicDefault' => [ 'use' => [ 'ScriptPath' ] ]
    ]

The URL path to index.php.

Defaults to "{$wgScriptPath}/index.php".

Definition at line 361 of file MainConfigSchema.php.

◆ ScriptPath

const MediaWiki\MainConfigSchema::ScriptPath

Initial value:

= [
        'default' => '/wiki',
    ]

The path we should point to.

It might be a virtual path in case with use apache mod_rewrite for example.

This needs to be set correctly.

Other paths will be set to defaults based on it unless they are directly set in LocalSettings.php

Definition at line 321 of file MainConfigSchema.php.

◆ SearchForwardUrl

const MediaWiki\MainConfigSchema::SearchForwardUrl

Initial value:

= [
        'default' => null,
    ]

Set this to a URL to forward search requests to some external location.

If the URL includes '$1', this will be replaced with the URL-encoded search term. Before using this, $wgDisableTextSearch must be set to true.

Example: To forward to Google you'd have something like:

$wgSearchForwardUrl =
'https://www.google.com/search?q=$1' .
'&domains=https://example.com' .
'&sitesearch=https://example.com' .
'&ie=utf-8&oe=utf-8';

◆ SearchHighlightBoundaries

const MediaWiki\MainConfigSchema::SearchHighlightBoundaries

Initial value:

= [
        'default' => '[\\p{Z}\\p{P}\\p{C}]',
    ]

Regexp to match word boundaries, defaults for non-CJK languages should be empty for CJK since the words are not separate.

◆ SearchMatchRedirectPreference

const MediaWiki\MainConfigSchema::SearchMatchRedirectPreference

Initial value:

= [
        'default' => false,
        'type' => 'boolean',
    ]

Set true to allow logged-in users to set a preference whether or not matches in search results should force redirection to that page.

If false, the preference is not exposed and cannot be altered from site default. To change your site's default preference, set via $wgDefaultUserOptions['search-match-redirect'].

Since: 1.35

◆ SearchRunSuggestedQuery

const MediaWiki\MainConfigSchema::SearchRunSuggestedQuery

Initial value:

= [
        'default' => true,
        'type' => 'boolean',
    ]

Controls whether zero-result search queries with suggestions should display results for these suggestions.

Since: 1.26

◆ SearchSuggestCacheExpiry

const MediaWiki\MainConfigSchema::SearchSuggestCacheExpiry

Initial value:

= [
        'default' => 1200,
    ]

Expiry time for search suggestion responses.

Definition at line 9709 of file MainConfigSchema.php.

◆ SearchType

const MediaWiki\MainConfigSchema::SearchType

Initial value:

= [
        'default' => null,
    ]

Search type.

Leave as null to select the default search engine for the selected database type (eg SearchMySQL), or set to a class name to override to a custom search engine.

If the canonical name for the search engine doesn't match the class name (because it's namespaced for example), you can add a mapping for this in SearchMappings in extension.json.

Definition at line 2897 of file MainConfigSchema.php.

◆ SearchTypeAlternatives

const MediaWiki\MainConfigSchema::SearchTypeAlternatives

Initial value:

= [
        'default' => null,
    ]

Alternative search types.

Sometimes you want to support multiple search engines for testing. This allows users to select their search engine of choice via url parameters to Special:Search and the action=search API. If using this, there's no need to add $wgSearchType to it, that is handled automatically.

If the canonical name for the search engine doesn't match the class name (because it's namespaced for example), you can add a mapping for this in SearchMappings in extension.json.

Definition at line 2913 of file MainConfigSchema.php.

◆ SecretKey

const MediaWiki\MainConfigSchema::SecretKey

Initial value:

= [
        'default' => false,
    ]

This should always be customised in LocalSettings.php.

Definition at line 8744 of file MainConfigSchema.php.

◆ SecureLogin

const MediaWiki\MainConfigSchema::SecureLogin

Initial value:

= [
        'default' => false,
    ]

This is to let user authenticate using https when they come from http.

Based on an idea by George Herbert on wikitech-l: https://lists.wikimedia.org/pipermail/wikitech-l/2010-October/050039.html

◆ SemiprotectedRestrictionLevels

const MediaWiki\MainConfigSchema::SemiprotectedRestrictionLevels

Initial value:

= [
        'default' => [ 'autoconfirmed', ],
        'type' => 'list',
    ]

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.

Definition at line 7895 of file MainConfigSchema.php.

◆ Send404Code

const MediaWiki\MainConfigSchema::Send404Code

Initial value:

= [
        'default' => 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.

Definition at line 5226 of file MainConfigSchema.php.

◆ Server

const MediaWiki\MainConfigSchema::Server

Initial value:

= [
        'default' => false,
    ]

URL of the server.

Example:

$wgServer = 'http://example.com';

$wgServer

Config variable stub for the Server setting, for use by phpdoc and IDEs.

Definition config-vars.php:25

This must be set in LocalSettings.php. The MediaWiki installer does this automatically since 1.18.

If you want to use protocol-relative URLs on your wiki, set this to a protocol-relative URL like '//example.com' and set $wgCanonicalServer to a fully qualified URL.

Definition at line 237 of file MainConfigSchema.php.

◆ ServerName

const MediaWiki\MainConfigSchema::ServerName

Initial value:

= [
        'default' => false,
    ]

Server name.

This is automatically computed by parsing the bare hostname out of $wgCanonicalServer. It should not be customized.

Since: 1.24

Definition at line 260 of file MainConfigSchema.php.

◆ ServiceWiringFiles

const MediaWiki\MainConfigSchema::ServiceWiringFiles

Initial value:

= [
        'default' => [],
        'type' => 'list',
    ]

List of service wiring files to be loaded by the default instance of MediaWikiServices.

Each file listed here is expected to return an associative array mapping service names to instantiator functions. Extensions may add wiring files to define their own services. However, this cannot be used to replace existing services - use the MediaWikiServices hook for that.

Note: the default wiring file will be added automatically by Setup.php

See also: MediaWikiServices; ServiceContainer::loadWiringFiles() for details on loading service instantiator functions.; docs/Injection.md for an overview of dependency injection in MediaWiki.

const MediaWiki\MainConfigSchema::SessionInsecureSecrets

Initial value:

= [
        'default' => false,
    ]

If for some reason you can't install the PHP OpenSSL extension, you can set this to true to make MediaWiki work again at the cost of storing sensitive session data insecurely.

But it would be much more secure to just install the OpenSSL extension.

◆ SharedDB

const MediaWiki\MainConfigSchema::SharedDB

Initial value:

= [
        'default' => 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.

◆ ShellCgroup

const MediaWiki\MainConfigSchema::ShellCgroup

Initial value:

= [
        'default' => 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

    ]

Whether to use a Host header in purge requests sent to the proxy servers configured in $wgCdnServers.

Set this to false to support a CDN configured in forward-proxy mode.

If this is set to true, a Host header will be sent, and only the path component of the URL will appear on the request line, as if the request were a non-proxy HTTP 1.1 request. Varnish only supports this style of request. Squid supports this style of request only if reverse-proxy mode (http_port ... accel) is enabled.

If this is set to false, no Host header will be sent, and the absolute URL will be sent in the request line, as is the standard for an HTTP proxy request in both HTTP 1.0 and 1.1. This style of request is not supported by Varnish, but is supported by Squid in either configuration (forward or reverse).

Since: 1.21

Deprecated: since 1.33, will always be true in a future release.

    ]

Determines which types of text are parsed as wikitext.

This does not imply that these kinds of texts are also rendered as wikitext, it only means that links, magic words, etc will have the effect on the database they would have on a wikitext page.

Note that table of contents information will be suppressed for all text models in this list other than wikitext.

Todo: Make the ToC suppression configurable by the content model (T313455), not a side effect of inclusion here.

◆ ThumbnailBuckets

const MediaWiki\MainConfigSchema::ThumbnailBuckets

Initial value:

= [
        'default' => null,
        'type' => '?list',
    ]

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.

Definition at line 2295 of file MainConfigSchema.php.

◆ ThumbnailEpoch

const MediaWiki\MainConfigSchema::ThumbnailEpoch

Initial value:

= [
        'default' => '20030516000000',
    ]

If rendered thumbnail files are older than this timestamp, they will be rerendered on demand as if the file didn't already exist.

Update if there is some need to force thumbs and SVG rasterizations to rerender, such as fixes to rendering bugs.

Definition at line 2019 of file MainConfigSchema.php.

◆ ThumbnailMinimumBucketDistance

const MediaWiki\MainConfigSchema::ThumbnailMinimumBucketDistance

Initial value:

= [
        'default' => 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.

Definition at line 2315 of file MainConfigSchema.php.

◆ ThumbnailScriptPath

const MediaWiki\MainConfigSchema::ThumbnailScriptPath

Initial value:

= [
        'default' => false,
    ]

Give a path here to use thumb.php for thumbnail generation on client request, instead of generating them on render and outputting a static URL.

This is necessary if some of your apache servers don't have read/write access to the thumbnail path.

Example:

$wgThumbnailScriptPath = "{$wgScriptPath}/thumb.php";

$wgThumbnailScriptPath

Config variable stub for the ThumbnailScriptPath setting, for use by phpdoc and IDEs.

This is used to interpret the request URL for requests to thumb_handler.php that do not match the base upload path.

Since: 1.36

Definition at line 575 of file MainConfigSchema.php.

◆ ThumbUpright

const MediaWiki\MainConfigSchema::ThumbUpright

Initial value:

= [
        'default' => 0.75,
    ]

Adjust width of upright images when parameter 'upright' is used This allows a nicer look for upright images without the need to fix the width by hardcoded px in wiki sourcecode.

Definition at line 2404 of file MainConfigSchema.php.

◆ TidyConfig

const MediaWiki\MainConfigSchema::TidyConfig

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

Configuration for HTML postprocessing tool.

Set this to a configuration array to enable an external tool. By default, we now use the RemexHtml library; historically, other postprocessors were used.

Setting this to null will use default settings.

Keys include:

treeMutationTrace: a boolean to turn on Remex tracing
serializerTrace: a boolean to turn on Remex tracing
mungerTrace: a boolean to turn on Remex tracing
pwrap: whether

wrapping should be done (default true)

See includes/tidy/RemexDriver.php for detail on configuration.

Overriding the default configuration is strongly discouraged in production.

◆ TiffThumbnailType

const MediaWiki\MainConfigSchema::TiffThumbnailType

Initial value:

= [
        'default' => [],
        'type' => 'list',
        'mergeStrategy' => 'replace',
    ]

Browsers don't support TIFF inline generally... For inline display, we need to convert to PNG or JPEG.

Note scaling should work with ImageMagick, but may not with GD scaling.

Example:

// PNG is lossless, but inefficient for photos
$wgTiffThumbnailType = [ 'png', 'image/png' ];
// JPEG is good for photos, but has no transparency support. Bad for diagrams.
$wgTiffThumbnailType = [ 'jpg', 'image/jpeg' ];

Definition at line 2006 of file MainConfigSchema.php.

◆ TmpDirectory

const MediaWiki\MainConfigSchema::TmpDirectory

Initial value:

= [
        'default' => false,
    ]

The local filesystem path to a temporary directory.

This must not be web accessible.

When this setting is set to false, its value will automatically be decided through the first call to wfTempDir(). See that method's implementation for the actual detection logic.

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

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

See also: \wfTempDir()

Note: Default changed to false in MediaWiki 1.20.

    ]

Array holding default tracking category names.

Array contains the system messages for each tracking category. Tracking categories allow pages with certain characteristics to be tracked. It works by adding any such page to a category automatically.

    ]

list of trusted media-types and MIME types.

Use the MEDIATYPE_xxx constants to represent media types. This list is used by File::isSafeFile

    ]

The maximum age of temporary (incomplete) uploaded files.

Definition at line 872 of file MainConfigSchema.php.

◆ UploadStashScalerBaseUrl

const MediaWiki\MainConfigSchema::UploadStashScalerBaseUrl

Initial value:

= [
        'default' => false,
        'deprecated' => 'since 1.36 Use thumbProxyUrl in $wgLocalFileRepo',
    ]

To enable remote on-demand scaling, set this to the thumbnail base URL.

Full thumbnail URL will be like $wgUploadStashScalerBaseUrl/e/e6/Foo.jpg/123px-Foo.jpg where 'e6' are the first two characters of the MD5 hash of the file name.

Deprecated: since 1.36 Use thumbProxyUrl in $wgLocalFileRepo

const MediaWiki\MainConfigSchema::UploadThumbnailRenderMap

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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

The idea is to prerender common thumbnail sizes, in order to avoid the necessity to render them on demand, which has a performance impact for the first client to view a certain size.

This obviously means that more disk space is needed per upload upfront.

Since: 1.25

Definition at line 2328 of file MainConfigSchema.php.

◆ UploadThumbnailRenderMethod

const MediaWiki\MainConfigSchema::UploadThumbnailRenderMethod

Initial value:

= [
        'default' => 'jobqueue',
    ]

The method through which the thumbnails will be prerendered for the entries in $wgUploadThumbnailRenderMap.

The method can be either "http" or "jobqueue". The former uses an http request to hit the thumbnail's URL. This method only works if thumbnails are configured to be rendered by a 404 handler. The latter option uses the job queue to render the thumbnail.

= [
        'default' => false,
    ]

Set this to true to maintain a copy of the message cache on the local server.

This layer of message cache is in addition to the one configured by $wgMessageCacheType.

The local copy is put in APC. If APC is not installed, this setting does nothing.

◆ UsePathInfo

const MediaWiki\MainConfigSchema::UsePathInfo

Initial value:

= [
        'dynamicDefault' => true,
    ]

Whether to support URLs like index.php/Page_title.

The effective default value is determined at runtime: it will be enabled in environments where it is expected to be safe.

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.

skin.json Example:

"ValidSkinNames": {
   "foobarskin": {
       "displayname": "FooBarSkin",
       "class": "MediaWiki\\\\Skins\\\\FooBar\\\\FooBarSkin"
   }
}

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

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

        ],
        'mergeStrategy' => 'array_plus_2d',
        'type' => 'map',
    ]

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', ];

            ]
        ],
        'type' => 'map',
    ]

Advanced WAN object cache configuration.

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

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

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

◆ XhtmlNamespaces

const MediaWiki\MainConfigSchema::XhtmlNamespaces

Initial value:

= [
        'default' => [],
        'type' => 'map',
    ]

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';

$wgXhtmlNamespaces

Config variable stub for the XhtmlNamespaces setting, for use by phpdoc and IDEs.

Definition config-vars.php:1921

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.

Initial value:

= [
        'default' => XML_DUMP_SCHEMA_VERSION_11,
    ]

The schema to use per default when generating XML dumps.

This allows sites to control explicitly when to make breaking changes to their export and dump format.

= [
        'default' => [

            'svg' => 'image/svg+xml',
            'http://www.lysator.liu.se/~alla/dia/:diagram' => 'application/x-dia-diagram',
            'http://www.w3.org/1999/xhtml:html' => 'text/html',
            'html' => 'text/html',
        ],
        'type' => 'map',
    ]
