439 * $wgLocalFileRepo is a single repository structure, and $wgForeignFileRepos is
440 * an array of such structures. Each repository structure is an associative
441 * array of properties configuring the repository.
442 *
443 * Properties required for all repos:
444 * - class The class name for the repository. May come from the core or an extension.
445 * The core repository classes are FileRepo, LocalRepo, ForeignDBRepo.
446 *
447 * - name A unique name for the repository (but $wgLocalFileRepo should be 'local').
448 * The name should consist of alpha-numeric characters.
449 * - backend A file backend name (see $wgFileBackends).
450 *
451 * For most core repos:
452 * - zones Associative array of zone names that each map to an array with:
453 * container : backend container name the zone is in
454 * directory : root path within container for the zone
455 * url : base URL to the root of the zone
456 * urlsByExt : map of file extension types to base URLs
457 * (useful for using a different cache for videos)
458 * Zones default to using "<repo name>-<zone name>" as the container name
459 * and default to using the container root as the zone's root directory.
460 * Nesting of zone locations within other zones should be avoided.
461 * - url Public zone URL. The 'zones' settings take precedence.
462 * - hashLevels The number of directory levels for hash-based division of files
463 * - thumbScriptUrl The URL for thumb.php (optional, not recommended)
464 * - transformVia404 Whether to skip media file transformation on parse and rely on a 404
465 * handler instead.
466 * - initialCapital Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE],
467 * determines whether filenames implicitly start with a capital letter.
468 * The current implementation may give incorrect description page links
469 * when the local $wgCapitalLinks and initialCapital are mismatched.
470 * - pathDisclosureProtection
471 * May be 'paranoid' to remove all parameters from error messages, 'none' to
472 * leave the paths in unchanged, or 'simple' to replace paths with
473 * placeholders. Default for LocalRepo is 'simple'.
474 * - fileMode This allows wikis to set the file mode when uploading/moving files. Default
475 * is 0644.
476 * - directory The local filesystem directory where public files are stored. Not used for
477 * some remote repos.
478 * - thumbDir The base thumbnail directory. Defaults to "<directory>/thumb".
479 * - thumbUrl The base thumbnail URL. Defaults to "<url>/thumb".
480 * - isPrivate Set this if measures should always be taken to keep the files private.
481 * One should not trust this to assure that the files are not web readable;
482 * the server configuration should be done manually depending on the backend.
483 *
484 * These settings describe a foreign MediaWiki installation. They are optional, and will be ignored
485 * for local repositories:
486 * - descBaseUrl URL of image description pages, e.g. https://en.wikipedia.org/wiki/File:
487 * - scriptDirUrl URL of the MediaWiki installation, equivalent to $wgScriptPath, e.g.
488 * https://en.wikipedia.org/w
489 * - scriptExtension Script extension of the MediaWiki installation, equivalent to
490 * $wgScriptExtension, e.g. ".php5". Defaults to ".php".
491 *
492 * - articleUrl Equivalent to $wgArticlePath, e.g. https://en.wikipedia.org/wiki/$1
493 * - fetchDescription Fetch the text of the remote file description page. Equivalent to
494 * $wgFetchCommonsDescriptions.
495 * - abbrvThreshold File names over this size will use the short form of thumbnail names.
496 * Short thumbnail names only have the width, parameters, and the extension.
497 *
498 * ForeignDBRepo:
499 * - dbType, dbServer, dbUser, dbPassword, dbName, dbFlags
500 * equivalent to the corresponding member of $wgDBservers
501 * - tablePrefix Table prefix, the foreign wiki's $wgDBprefix
502 * - hasSharedCache True if the wiki's shared cache is accessible via the local $wgMemc
503 *
504 * ForeignAPIRepo:
505 * - apibase Use for the foreign API's URL
506 * - apiThumbCacheExpiry How long to locally cache thumbs for
507 *

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

1253 * the file to have an unsupported format, which is probably immune to

1255 * - An exit code mapped to AV_NO_VIRUS will cause the file to pass, meaning
1256 * no virus was found.
1257 * - All other codes (like AV_VIRUS_FOUND) will cause the function to report
1258 * a virus.
1259 * - You may use "*" as a key in the array to catch all exit codes not mapped otherwise.
1260 *
1261 * "messagepattern" is a perl regular expression to extract the meaningful part of the scanners
