441 * File repository structures
442 *
443 * $wgLocalFileRepo is a single repository structure, and $wgForeignFileRepos is
444 * an array of such structures. Each repository structure is an associative
445 * array of properties configuring the repository.
446 *
447 * Properties required for all repos:
448 * - class The class name for the repository. May come from the core or an extension.
449 * The core repository classes are FileRepo, LocalRepo, ForeignDBRepo.
450 *
451 * - name A unique name for the repository (but $wgLocalFileRepo should be 'local').
452 * The name should consist of alpha-numeric characters.
453 * - backend A file backend name (see $wgFileBackends).
454 *
455 * For most core repos:
456 * - zones Associative array of zone names that each map to an array with:
457 * container : backend container name the zone is in
458 * directory : root path within container for the zone
459 * url : base URL to the root of the zone
460 * urlsByExt : map of file extension types to base URLs
461 * (useful for using a different cache for videos)
462 * Zones default to using "<repo name>-<zone name>" as the container name
463 * and default to using the container root as the zone's root directory.
464 * Nesting of zone locations within other zones should be avoided.
465 * - url Public zone URL. The 'zones' settings take precedence.
466 * - hashLevels The number of directory levels for hash-based division of files
467 * - thumbScriptUrl The URL for thumb.php (optional, not recommended)
468 * - transformVia404 Whether to skip media file transformation on parse and rely on a 404
469 * handler instead.
470 * - initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE],
471 * determines whether filenames implicitly start with a capital letter.
472 * The current implementation may give incorrect description page links
473 * when the local $wgCapitalLinks and initialCapital are mismatched.
474 * - pathDisclosureProtection
475 * May be 'paranoid' to remove all parameters from error messages, 'none' to
476 * leave the paths in unchanged, or 'simple' to replace paths with
477 * placeholders. Default for LocalRepo is 'simple'.
478 * - fileMode This allows wikis to set the file mode when uploading/moving files. Default
479 * is 0644.
480 * - directory The local filesystem directory where public files are stored. Not used for
481 * some remote repos.
482 * - thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
483 * - thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
484 * - isPrivate Set this if measures should always be taken to keep the files private.
485 * One should not trust this to assure that the files are not web readable;
486 * the server configuration should be done manually depending on the backend.
487 *
488 * These settings describe a foreign MediaWiki installation. They are optional, and will be ignored
489 * for local repositories:
490 * - descBaseUrl URL of image description pages, e.g. https://en.wikipedia.org/wiki/File:
491 * - scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g.
492 * https://en.wikipedia.org/w
493 * - articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
494 * - fetchDescription Fetch the text of the remote file description page. Equivalent to
495 * $wgFetchCommonsDescriptions.
496 * - abbrvThreshold File names over this size will use the short form of thumbnail names.
497 * Short thumbnail names only have the width, parameters, and the extension.
498 *
499 * ForeignDBRepo:
500 * - dbType, dbServer, dbUser, dbPassword, dbName, dbFlags
501 * equivalent to the corresponding member of $wgDBservers
502 * - tablePrefix Table prefix, the foreign wiki's $wgDBprefix
503 * - hasSharedCache True if the wiki's shared cache is accessible via the local $wgMemc
504 *
505 * ForeignAPIRepo:
506 * - apibase Use for the foreign API's URL
507 * - apiThumbCacheExpiry How long to locally cache thumbs for
508 *

606 * File backend structure configuration.
607 *
608 * This is an array of file backend configuration arrays.
609 * Each backend configuration has the following parameters:
610 * - 'name' : A unique name for the backend
611 * - 'class' : The file backend class to use
612 * - 'wikiId' : A unique string that identifies the wiki (container prefix)
613 * - 'lockManager' : The name of a lock manager (see $wgLockManagers)
614 *
615 * See FileBackend::__construct() for more details.
616 * Additional parameters are specific to the file backend class used.
617 * These settings should be global to all wikis when possible.
618 *
619 * FileBackendMultiWrite::__construct() is augmented with a 'template' option that
620 * can be used in any of the values of the 'backends' array. Its value is the name of
621 * another backend in $wgFileBackends. When set, it pre-fills the array with all of the
622 * configuration of the named backend. Explicitly set values in the array take precedence.
623 *
624 * There are two particularly important aspects about each backend:
625 * - a) Whether it is fully qualified or wiki-relative.
626 * By default, the paths of files are relative to the current wiki,
627 * which works via prefixing them with the current wiki ID when accessed.
628 * Setting 'wikiId' forces the backend to be fully qualified by prefixing
629 * all paths with the specified value instead. This can be useful if
630 * multiple wikis need to share the same data. Note that 'name' is *not*
631 * part of any prefix and thus should not be relied upon for namespacing.
632 * - b) Whether it is only defined for some wikis or is defined on all
633 * wikis in the wiki farm. Defining a backend globally is useful
634 * if multiple wikis need to share the same data.
635 * One should be aware of these aspects when configuring a backend for use with
636 * any basic feature or plugin. For example, suppose an extension stores data for
637 * different wikis in different directories and sometimes needs to access data from
638 * a foreign wiki's directory in order to render a page on given wiki. The extension
639 * would need a fully qualified backend that is defined on all wikis in the wiki farm.

1275 * - An exit code mapped to AV_NO_VIRUS will cause the file to pass, meaning
1276 * no virus was found.

1278 * a virus.
1279 * - You may use "*" as a key in the array to catch all exit codes not mapped otherwise.

3367 * - 'html5' is modern HTML5 style encoding with minimal escaping. Displays Unicode
3368 * characters in most browsers' address bars.
3369 * - 'legacy' is old MediaWiki-style encoding, e.g. 啤酒 turns into .E5.95.A4.E9.85.92
3370 * - 'html5-legacy' corresponds to DEPRECATED $wgExperimentalHtmlIds mode. DO NOT use
3371 * it for anything but migration off that mode (see below).
3372 *
3373 * The first element of this array specifies the primary mode of escaping IDs. This
3374 * is what users will see when they e.g. follow an [[#internal link]] to a section of
3375 * a page.
3376 *
3377 * The optional second element defines a fallback mode, useful for migrations.
3378 * If present, it will direct MediaWiki to add empty <span>s to every section with its
3379 * id attribute set to fallback encoded title so that links using the previous encoding
3380 * would still work.
3381 *
3382 * Example: you want to migrate your wiki from 'legacy' to 'html5'
3383 *
3384 * On the first step, set this variable to [ 'legacy', 'html5' ]. After a while, when
3385 * all caches (parser, HTTP, etc.) contain only pages generated with this setting,
3386 * flip the value to [ 'html5', 'legacy' ]. This will result in all internal links being
3387 * generated in the new encoding while old links (both external and cached internal) will
3388 * still work. After a long time, you might want to ditch backwards compatibility and
3389 * set it to [ 'html5' ]. After all, pages get edited, breaking incoming links no matter which
3390 * fragment mode is used.

3415 * turns it into mw_poweredby.

3418 * be used to find the icon and unset it or change the icon if needed.
3419 * This is useful for disabling icons that are set by extensions.
3420 * The value should be either a string or an array. If it is a string it will be output

3422 * for the icon, the following keys are used:

3426 * - url: The url to use in the a element around the text or icon, if not set an a element will
3427 * not be outputted

3429 * skins like Modern or if src is not set, and will otherwise be used as
3430 * the alt="" for the image. This key is required.
3431 * - width and height: If the icon specified by src is not of the standard size
3432 * you can specify the size of image to use with these keys.
