448 * File repository structures
449 *
450 * $wgLocalFileRepo is a single repository structure, and $wgForeignFileRepos is
451 * an array of such structures. Each repository structure is an associative
452 * array of properties configuring the repository.
453 *
454 * Properties required for all repos:
455 * - class The class name for the repository. May come from the core or an extension.
456 * The core repository classes are FileRepo, LocalRepo, ForeignDBRepo.
457 *
458 * - name A unique name for the repository (but $wgLocalFileRepo should be 'local').
459 * The name should consist of alpha-numeric characters.
460 * - backend A file backend name (see $wgFileBackends).
461 *
462 * For most core repos:
463 * - zones Associative array of zone names that each map to an array with:
464 * container : backend container name the zone is in
465 * directory : root path within container for the zone
466 * url : base URL to the root of the zone
467 * urlsByExt : map of file extension types to base URLs
468 * (useful for using a different cache for videos)
469 * Zones default to using "<repo name>-<zone name>" as the container name
470 * and default to using the container root as the zone's root directory.
471 * Nesting of zone locations within other zones should be avoided.
472 * - url Public zone URL. The 'zones' settings take precedence.
473 * - hashLevels The number of directory levels for hash-based division of files
474 * - thumbScriptUrl The URL for thumb.php (optional, not recommended)
475 * - transformVia404 Whether to skip media file transformation on parse and rely on a 404
476 * handler instead.
477 * - initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE],
478 * determines whether filenames implicitly start with a capital letter.
479 * The current implementation may give incorrect description page links
480 * when the local $wgCapitalLinks and initialCapital are mismatched.
481 * - pathDisclosureProtection
482 * May be 'paranoid' to remove all parameters from error messages, 'none' to
483 * leave the paths in unchanged, or 'simple' to replace paths with
484 * placeholders. Default for LocalRepo is 'simple'.
485 * - fileMode This allows wikis to set the file mode when uploading/moving files. Default
486 * is 0644.
487 * - directory The local filesystem directory where public files are stored. Not used for
488 * some remote repos.
489 * - thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
490 * - thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
491 * - isPrivate Set this if measures should always be taken to keep the files private.
492 * One should not trust this to assure that the files are not web readable;
493 * the server configuration should be done manually depending on the backend.
494 *
495 * These settings describe a foreign MediaWiki installation. They are optional, and will be ignored
496 * for local repositories:

498 * - scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g.
499 * https://en.wikipedia.org/w
500 * - articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
501 * - fetchDescription Fetch the text of the remote file description page and display them
502 * on the local wiki.
503 * - abbrvThreshold File names over this size will use the short form of thumbnail names.
504 * Short thumbnail names only have the width, parameters, and the extension.
505 *
506 * ForeignDBRepo:
507 * - dbType, dbServer, dbUser, dbPassword, dbName, dbFlags
508 * equivalent to the corresponding member of $wgDBservers
509 * - tablePrefix Table prefix, the foreign wiki's $wgDBprefix
510 * - hasSharedCache Set to true if the foreign wiki's $wgMainCacheType is identical to,
511 * and accesible from, this wiki.
512 *
513 * ForeignAPIRepo:
514 * - apibase Use for the foreign API's URL
515 * - apiThumbCacheExpiry How long to locally cache thumbs for
516 *

730 * File backend structure configuration.
731 *
732 * This is an array of file backend configuration arrays.
733 * Each backend configuration has the following parameters:
734 * - 'name' : A unique name for the backend
735 * - 'class' : The file backend class to use
736 * - 'wikiId' : A unique string that identifies the wiki (container prefix)
737 * - 'lockManager' : The name of a lock manager (see $wgLockManagers)
738 *
739 * See FileBackend::__construct() for more details.
740 * Additional parameters are specific to the file backend class used.
741 * These settings should be global to all wikis when possible.
742 *
743 * FileBackendMultiWrite::__construct() is augmented with a 'template' option that
744 * can be used in any of the values of the 'backends' array. Its value is the name of
745 * another backend in $wgFileBackends. When set, it pre-fills the array with all of the
746 * configuration of the named backend. Explicitly set values in the array take precedence.
747 *
748 * There are two particularly important aspects about each backend:
749 * - a) Whether it is fully qualified or wiki-relative.
750 * By default, the paths of files are relative to the current wiki,
751 * which works via prefixing them with the current wiki ID when accessed.
752 * Setting 'domainId' forces the backend to be fully qualified by prefixing
753 * all paths with the specified value instead. This can be useful if
754 * multiple wikis need to share the same data. Note that 'name' is *not*
755 * part of any prefix and thus should not be relied upon for namespacing.
756 * - b) Whether it is only defined for some wikis or is defined on all
757 * wikis in the wiki farm. Defining a backend globally is useful
758 * if multiple wikis need to share the same data.
759 * One should be aware of these aspects when configuring a backend for use with
760 * any basic feature or plugin. For example, suppose an extension stores data for
761 * different wikis in different directories and sometimes needs to access data from
762 * a foreign wiki's directory in order to render a page on given wiki. The extension
763 * would need a fully qualified backend that is defined on all wikis in the wiki farm.
