$wgAllowPrefChange = array()

Policies for how each preference is allowed to be changed, in the presence of external authentication.

The keys are preference keys, e.g., 'password' or 'emailaddress' (see Preferences.php et al.). The value can be one of the following:

• local: Allow changes to this pref through the wiki interface but only apply them locally (default).
• semiglobal: Allow changes through the wiki interface and try to apply them to the foreign database, but continue on anyway if that fails.
• global: Allow changes through the wiki interface, but only let them go through if they successfully update the foreign database.
• message: Allow no local changes for linked accounts; replace the change form with a message provided by the auth plugin, telling the user how to change the setting externally (maybe providing a link, etc.). If the auth plugin provides no message for this preference, hide it entirely.

Accounts that are not linked to an external account are never affected by this setting. You may want to look at $wgHiddenPrefs instead. $wgHiddenPrefs supersedes this option.

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, plase 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 usupported format, which is probably imune to virusses. 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.

$wgCategoryCollation = '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 http://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.

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

• host: Host name
• dbname: Default database name
• user: DB user
• password: DB password
• type: "mysql" or "postgres"
• load: ratio of DB_SLAVE load, must be >=0, the sum of all loads must be >0
• groupLoads: array of load ratios, the key is the query group name. A query may belong to several groups, the most specific group defined here is used.

• flags: bit field
  • DBO_DEFAULT -- turns on DBO_TRX only if !$wgCommandLineMode (recommended)
  • DBO_DEBUG -- equivalent of $wgDebugDumpSql
  • DBO_TRX -- wrap entire request in a transaction
  • DBO_IGNORE -- ignore errors (not useful in LocalSettings.php)
  • DBO_NOBUFFER -- turn off buffering (not useful in LocalSettings.php)

• max lag: (optional) Maximum replication lag before a slave will taken out of rotation
• max threads: (optional) Maximum number of running threads

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

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

The first server listed in this array (with key 0) will be the master. The rest of the servers will be slaves. To prevent writes to your slaves due to accidental misconfiguration or MediaWiki bugs, set read_only=1 on all your slaves in my.cnf. You can set read_only mode at runtime using:

SET @read_only=1;

Since the effect of writing to a slave is so damaging and difficult to clean up, we at Wikimedia set read_only=1 in my.cnf on all our DB servers, even our masters, and then set read_only=0 on masters at runtime.

• '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.

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 url: The url to use in the arround the text or icon, if not set an will not be outputted alt: This is the text form of the icon, it will be displayed without an image in skins like Modern or if src is not set, and will otherwise be used as the alt="" for the image. This key is required. width and height: If the icon specified by src is not of the standard size you can specify the size of image to use with these keys. Otherwise they will default to the standard 88x31.

$wgForceUIMsgAsContentMsg = array()

When translating messages with wfMsg(), 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 wfMsgForContent(), but for rendering the text of the link, we call wfMsg(). 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. For example, to allow language-specific main page and community portal, set

$wgForceUIMsgAsContentMsg = array( 'mainpage', 'portal-url' );

All users are implicitly in the '*' group including anonymous visitors; logged-in users are all implicitly in the 'user' group. These will be combined with the permissions of all groups that a given user is listed in in the user_groups table.

Note: Don't set $wgGroupPermissions = array(); 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.

Consider only using this if you have a *really good* handheld stylesheet, as iPhone users won't have any way to disable it and use the "grown-up" styles instead.

$wgHandheldStyle = false

Optionally, we can specify a stylesheet to use for media="handheld".

This is recognized by some, but not all, handheld/mobile/PDA browsers. If left empty, compliant handheld browsers won't pick up the skin stylesheet, which is specified for 'screen' media.

Can be a complete URL, base-relative path, or $wgStylePath-relative path. Try 'chick/main.css' to apply the Chick styles to the MonoBook HTML.

Will also be switched in when 'handheld=yes' is added to the URL, like the 'printable=yes' mode for print media.

$wgHashedSharedUploadDirectory = true

$wgHashedUploadDirectory = true

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

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

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

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

Problematic punctuation:

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

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

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

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

Theoretically 0x80-0x9F of ISO 8859-1 should be disallowed, but this breaks interlanguage links

$wgLocalFileRepo = false

File repository structures.

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

Properties required for all repos:

• class The class name for the repository. May come from the core or an extension. The core repository classes are FileRepo, LocalRepo, ForeignDBRepo. FSRepo is also supported for backwards compatibility.

• name A unique name for the repository (but $wgLocalFileRepo should be 'local'). The name should consist of alpha-numberic characters.
• backend A file backend name (see $wgFileBackends).

For most core repos:

• zones Associative array of zone names that each map to an array with: container : backend container name the zone is in directory : root path within container for the zone Zones default to using <repo name>="">-<zone> as the container name and the container root as the zone directory.
• url Base public URL
• hashLevels The number of directory levels for hash-based division of files
• thumbScriptUrl The URL for thumb.php (optional, not recommended)
• transformVia404 Whether to skip media file transformation on parse and rely on a 404 handler instead.
• initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE], determines whether filenames implicitly start with a capital letter. The current implementation may give incorrect description page links when the local $wgCapitalLinks and initialCapital are mismatched.
• pathDisclosureProtection May be 'paranoid' to remove all parameters from error messages, 'none' to leave the paths in unchanged, or 'simple' to replace paths with placeholders. Default for LocalRepo is 'simple'.
• fileMode This allows wikis to set the file mode when uploading/moving files. Default is 0644.
• directory The local filesystem directory where public files are stored. Not used for some remote repos.
• thumbDir The base thumbnail directory. Defaults to <directory>/thumb.
• thumbUrl The base thumbnail URL. Defaults to <url>/thumb.

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. http://en.wikipedia.org/wiki/File:
• scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g. http://en.wikipedia.org/w
• scriptExtension Script extension of the MediaWiki installation, equivalent to $wgScriptExtension, e.g. .php5 defaults to .php

• articleUrl Equivalent to $wgArticlePath, e.g. http://en.wikipedia.org/wiki/$1
• fetchDescription Fetch the text of the remote file description page. Equivalent to $wgFetchCommonsDescriptions.

ForeignDBRepo:

• dbType, dbServer, dbUser, dbPassword, dbName, dbFlags equivalent to the corresponding member of $wgDBservers
• tablePrefix Table prefix, the foreign wiki's $wgDBprefix
• hasSharedCache True if the wiki's shared cache is accessible via the local $wgMemc

ForeignAPIRepo:

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

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

$wgMainCacheType = 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 database is not fast enough to make it worthwhile.

The options are:

• CACHE_NONE: Do not cache
• CACHE_DB: Store cache objects in the DB
• CACHE_MEMCACHED: MemCached, must specify servers in $wgMemCachedServers
• CACHE_ACCEL: APC, XCache or WinCache
• CACHE_DBA: Use PHP's DBA extension to store in a DBM-style database. This is slow, and is not recommended for anything other than debugging.
• (other): A string may be used which identifies a cache configuration in $wgObjectCaches.

$wgMaxImageArea = 1.25e7

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.

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

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 or $wgParserCacheType.

The format is an associative array where the key is a cache identifier, and the value is an associative array of parameters. The "class" parameter is the class name which will be used. Alternatively, a "factory" parameter may be given, giving a callable function which will generate a suitable cache object.

The other parameters are dependent on the class used.

• CACHE_DBA uses $wgTmpDirectory by default. The 'dir' parameter let you overrides that.

$wgParserConf

Initial value:

 array(
        'class' => 'Parser',
        #'preprocessorClass' => 'Preprocessor_Hash',
)

Parser configuration.

Associative array with the following members:

class The class name

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

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

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

$wgSharedDB = null

Shared database for multiple wikis.

Commonly used for storing a user table for single sign-on. The server for this database must be the same as for the main database.

For backwards compatibility the shared prefix is set to the same as the local prefix, and the user table is listed in the default list of shared tables. The user_properties table is also added so that users will continue to have their preferences shared (preferences were stored in the user table prior to 1.16)

$wgSharedTables may be customized with a list of tables to share in the shared datbase. 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. EXPERIMENTAL

$wgSharedPrefix is the table prefix for the shared database. It defaults to $wgDBprefix.

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

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

Should we try to make our HTML output well-formed XML? If set to false, output will be a few bytes shorter, and the HTML will arguably be more readable.

If set to true, life will be much easier for the authors of screen-scraping bots, and the HTML will arguably be more readable.

Setting this to false may omit quotation marks on some attributes, omit slashes from some self-closing tags, omit some ending tags, etc., where permitted by HTML5. Setting it to true will not guarantee that all pages will be well-formed, although non-well-formed pages should be rare and it's a bug if you find one. Conversely, setting it to false doesn't mean that all XML-y constructs will be omitted, just that they might be.

Because of compatibility with screen-scraping bots, and because it's controversial, this is currently left to true by default.
