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.

= [
        '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

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.

        '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.

                '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.

'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 ) { ... }
];

        'type' => 'object',
    ]

Configuration for automatic creation of temporary accounts on page save.

This can be enabled to avoid exposing the IP addresses of casual editors who do not explicitly create an account.

EXPERIMENTAL – enabling may break extensions.

An associative array with the following keys:

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. This is ignored if "enabled" is false.
reservedPattern: (string) A pattern used to determine whether a username should be denied for explicit creation, in addition to matchPattern. This is used even if "enabled" is false.
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.

expireAfterDays: (int|null, default null) If set, how many days should the temporary accounts expire? Require expireTemporaryAccounts.php to be periodically executed in order to work.

◆ AutoloadAttemptLowercase

const MediaWiki\MainConfigSchema::AutoloadAttemptLowercase

Initial value:

= [
        'default' => false,
        'obsolete' => 'Since 1.40; no longer has any effect.',
        'description' => 'Has been emitting warnings since 1.39 (LTS). ' .
            'Can be removed completely in 1.44, assuming 1.43 is an LTS release.'
    ]

Obsolete switch that controlled legacy case-insensitive classloading.

Case-insensitive classloading was needed for loading data that had been serialized by PHP 4 with the class names converted to lowercase. It is no longer necessary since 1.31; the lowercase forms in question are now listed in autoload.php (T166759).

Deprecated:: since 1.35

Definition at line 11139 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.

◆ AutopromoteOnce

const MediaWiki\MainConfigSchema::AutopromoteOnce

    ]

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

Rights in this list are denied unless explicitly granted, typically using GroupPermissions.

For extensions only.

Definition at line 8404 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.

◆ 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 7729 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, sitewide blocked users will not be allowed to login.

const MediaWiki\MainConfigSchema::CacheDirectory

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

◆ 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.

◆ 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.

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).

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.

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.

◆ DebugLogGroups

const MediaWiki\MainConfigSchema::DebugLogGroups

Initial value:

= [
        'default' => [],

    ]

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)

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

Definition at line 2773 of file MainConfigSchema.php.

◆ EnotifMaxRecips

const MediaWiki\MainConfigSchema::EnotifMaxRecips

Initial value:

= [
        'default' => 500,
    ]

Maximum number of users to mail at once when using impersonal mail.

Should match the limit on your mail server.

Definition at line 2781 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 2762 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 2744 of file MainConfigSchema.php.

◆ EnotifUseRealName

const MediaWiki\MainConfigSchema::EnotifUseRealName

Initial value:

= [
        'default' => false,
    ]

Use real name instead of username in e-mail "from" field.

Definition at line 2788 of file MainConfigSchema.php.

◆ EnotifUserTalk

const MediaWiki\MainConfigSchema::EnotifUserTalk

Initial value:

= [
        'default' => false,
    ]

Allow users to enable email notification ("enotif") when someone edits their user talk page.

The owner of the user talk page must also have the 'enotifusertalkpages' user preference set to true.

Definition at line 2728 of file MainConfigSchema.php.

◆ EnotifWatchlist

const MediaWiki\MainConfigSchema::EnotifWatchlist

Initial value:

= [
        'default' => false,
    ]

Allow users to enable email notification ("enotif") on watchlist changes.

Definition at line 2717 of file MainConfigSchema.php.

◆ 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.

◆ ExemptFromUserRobotsControl

const MediaWiki\MainConfigSchema::ExemptFromUserRobotsControl

Initial value:

= [
        '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.

If set to null, default to $wgContentNamespaces.

Example:

$wgExemptFromUserRobotsControl = [ NS_MAIN, NS_TALK, NS_PROJECT ];

NS_TALK

const NS_TALK

◆ ExportAllowAll

const MediaWiki\MainConfigSchema::ExportAllowAll

Initial value:

= [
        'default' => false,
    ]

Whether to allow exporting the entire wiki into a single file.

◆ 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 10893 of file MainConfigSchema.php.

◆ ExportAllowListContributors

const MediaWiki\MainConfigSchema::ExportAllowListContributors

Initial value:

= [
        'default' => false,

Return distinct author list (when not returning full history)

Definition at line 10909 of file MainConfigSchema.php.

◆ ExportFromNamespaces

const MediaWiki\MainConfigSchema::ExportFromNamespaces

Initial value:

= [
        'default' => false,
    ]

Whether to allow the "export all pages in namespace" option.

Definition at line 10931 of file MainConfigSchema.php.

◆ ExportMaxHistory

const MediaWiki\MainConfigSchema::ExportMaxHistory

Initial value:

= [
        'default' => 0,
    ]

If set nonzero, Special:Export requests for history of pages with more revisions than this will be rejected.

On some big sites things could get bogged down by very very long pages.

Definition at line 10902 of file MainConfigSchema.php.

◆ 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.

◆ ExtendedLoginCookieExpiration

const MediaWiki\MainConfigSchema::ExtendedLoginCookieExpiration

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.

Definition at line 9302 of file MainConfigSchema.php.

◆ ExtensionAssetsPath

const MediaWiki\MainConfigSchema::ExtensionAssetsPath

Initial value:

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

The URL path of the extensions directory.

Defaults to "{$wgResourceBasePath}/extensions".

Since: 1.16

Definition at line 467 of file MainConfigSchema.php.

◆ 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).

◆ ExtensionEntryPointListFiles

const MediaWiki\MainConfigSchema::ExtensionEntryPointListFiles

Initial value:

= [

◆ 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 11001 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:1657

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 4418 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

◆ ExternalDiffEngine

const MediaWiki\MainConfigSchema::ExternalDiffEngine

    ]

Name of the external diff engine to use.

◆ 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 5312 of file MainConfigSchema.php.

◆ ExternalLinksDomainGaps

const MediaWiki\MainConfigSchema::ExternalLinksDomainGaps

Initial value:

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

Gaps in the externallinks table for certain domains.

If you have identified certain domains for which externallinks searches are slow, you can use this setting to make MediaWiki skip large el_id ranges, rather than having the database scan through them fruitlessly.

Each key in the array is a domain name in el_to_domain_index form, e.g. 'https://com.example.'. The value is an array with integer keys and values, where each entry is a range (from => to, both inclusive) of el_id values where this domain is known to have no entries. (Subdomains are included, i.e., configuring an entry here guarantees to MediaWiki that there are no rows where the el_to_domain_index starts with this value.)

◆ 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.

◆ 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.

◆ ExtraInterlanguageLinkPrefixes

const MediaWiki\MainConfigSchema::ExtraInterlanguageLinkPrefixes

Initial value:

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

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.
This should be a list of "interwiki prefixes" (ie, what appears in wikitext), and you probably want to add an entry to InterlanguageLinkCodeMap as well to specify which mediawiki internal (or custom) language code this prefix corresponds to, and perhaps then map that custom language code to a language name in ExtraLanguageNames.

Definition at line 4769 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 4808 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 4789 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"
];

        '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.

◆ 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 4349 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".

Definition at line 606 of file MainConfigSchema.php.

◆ FileExtensions

const MediaWiki\MainConfigSchema::FileExtensions

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).

◆ FilterLogTypes

const MediaWiki\MainConfigSchema::FilterLogTypes

Initial value:

= [
        'default' => [
            'patrol' => true,
            'tag' => true,
            '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.

◆ FixDoubleRedirects

const MediaWiki\MainConfigSchema::FixDoubleRedirects

Initial value:

= [
        'default' => false,

◆ FooterIcons

const MediaWiki\MainConfigSchema::FooterIcons

Initial value:

= [
        'default' => [
            "copyright" => [

                    "src" => null,
                    "url" => "https://www.mediawiki.org/",
                    "alt" => "Powered by MediaWiki",
                ]
            ],
        ],
        'type' => 'map',
    ]

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' => 300,
    ]

Default maximum age for raw CSS/JS accesses.

300 seconds = 5 minutes.

Definition at line 4551 of file MainConfigSchema.php.

◆ 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.

Since: 1.35

Definition at line 312 of file MainConfigSchema.php.

◆ 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' ];

$wgForceUIMsgAsContentMsg

◆ 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).

Since: 1.11

◆ ForeignUploadTargets

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' ];

Definition at line 1291 of file MainConfigSchema.php.

◆ 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:

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

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.
Deprecated:

◆ 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;

Directory where GitInfo will look for pre-computed cache files.

If false, $wgCacheDirectory/gitinfo will be used.

Definition at line 4330 of file MainConfigSchema.php.

◆ GitRepositoryViewers

const MediaWiki\MainConfigSchema::GitRepositoryViewers

Initial value:

= [
        'default' => [

        ],
        '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

◆ GrantPermissionGroups

const MediaWiki\MainConfigSchema::GrantPermissionGroups

Grant groups are used on some user interfaces to display conceptually similar grants together.

This configuration value should usually be set by extensions, not site administrators.

See also: self::GrantPermissions

Since: 1.27

Definition at line 8976 of file MainConfigSchema.php.

◆ 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.

Since: 1.27

◆ GroupInheritsPermissions

const MediaWiki\MainConfigSchema::GroupInheritsPermissions

= [
        '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:2786

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 8072 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!

This replaces $wgWhitelistAccount and $wgWhitelistEdit

◆ GroupsAddToSelf

const MediaWiki\MainConfigSchema::GroupsAddToSelf

Initial value:

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

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

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

Example: To allow sysops to add themselves to the "bot" group:

$wgGroupsAddToSelf = [ 'sysop' => [ 'bot' ] ];

$wgGroupsAddToSelf

◆ 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' => true,
    ]

Temporary variable that allows HTMLForms to be rendered as tables.

Table based layouts cause various issues when designing for mobile. This global allows skins or extensions a means to force non-table based rendering. Setting to false forces form components to always render as div elements.

◆ HTTPConnectTimeout

const MediaWiki\MainConfigSchema::HTTPConnectTimeout

Initial value:

= [

const MediaWiki\MainConfigSchema::HTTPMaxConnectTimeout

Initial value:

= [
        'default' => 0,
        'type' => 'float',
    ]

The maximum HTTP connect timeout in seconds.

If any specified or configured connect timeout is larger than this, then this value will be used instead. Zero is interpreted as "no limit".

Since: 1.35

Definition at line 12387 of file MainConfigSchema.php.

◆ HTTPMaxTimeout

const MediaWiki\MainConfigSchema::HTTPMaxTimeout

Initial value:

= [
        'default' => 0,
        'type' => 'float',
    ]

The maximum HTTP request timeout in seconds.

If any specified or configured request timeout is larger than this, then this value will be used instead. Zero is interpreted as "no limit".

◆ HTTPProxy

const MediaWiki\MainConfigSchema::HTTPProxy

Initial value:

= [
        'default' => '',
    ]

Proxy to use for CURL requests.

Definition at line 12411 of file MainConfigSchema.php.

◆ HttpsPort

const MediaWiki\MainConfigSchema::HttpsPort

Initial value:

= [
        'default' => 443,
    ]

For installations where the canonical server is HTTP but HTTPS is optionally supported, you can specify a non-standard HTTPS port here.

$wgServer should be a protocol-relative URL.

If HTTPS is always used, just specify the port number in $wgServer.

◆ HTTPTimeout

const MediaWiki\MainConfigSchema::HTTPTimeout

Initial value:

= [
        'default' => 25,
        'type' => 'float',
    ]

Timeout for HTTP requests done internally, in seconds.

◆ IgnoreImageErrors

const MediaWiki\MainConfigSchema::IgnoreImageErrors

Initial value:

= [
        'default' => false,
    ]

If set, inline scaled images will still produce "<img>" tags ready for output instead of showing an error message.

This may be useful if errors are transitory, especially if the site is configured to automatically render thumbnails on request.

On the other hand, it may obscure error conditions from debugging. Enable the debug log or the 'thumbnail' log group to make sure errors are logged to a file for review.

◆ IllegalFileChars

const MediaWiki\MainConfigSchema::IllegalFileChars

Initial value:

= [
        'default' => ':\\/\\\\',
        'deprecated' => 'since 1.41; no longer customizable',
    ]

Additional characters that are not allowed in filenames.

They are replaced with '-' when uploading. Like $wgLegalTitleChars, this is a regexp character class.

Slashes and backslashes are disallowed regardless of this setting, but included here for completeness.

Deprecated:: since 1.41; no longer customizable

◆ ImageLimits

const MediaWiki\MainConfigSchema::ImageLimits

Initial value:

= [
        'default' => [
            [ 320, 240 ],
            [ 640, 480 ],
            [ 800, 600 ],
            [ 1024, 768 ],
            [ 1280, 1024 ],
            [ 2560, 2048 ],
        ],
        'type' => 'list',
    ]

Limit images on image description pages to a user-selectable limit.

In order to reduce disk usage, limits can only be selected from this list. The user preference is saved as an array offset in the database, by default the offset is set with $wgDefaultUserOptions['imagesize']. Make sure you change it if you alter the array (see T10858).

This list is also used by ImagePage for alternate size links.

◆ ImageMagickConvertCommand

const MediaWiki\MainConfigSchema::ImageMagickConvertCommand

Initial value:

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

◆ 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 1817 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 934 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 571 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:

= [
