Manual:$wgLocalFileRepo

Details
This config is for customizing the local (primary) file repo that MediaWiki uses. Most users will not want to customize this or will customize this indirectly via other variables such as $wgUploadDirectory.

More complex setups may requiring customizing this variable. For example, if you want to use a custom file backend, in order to replicate file storage amongst multiple data centers.

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
 * Should be set to.


 * backend
 * A file backend name (see  ). For $wgLocalFileRepo and , a name is automatically generated in  if not defined.

General parameters for LocalRepo class

 * initialCapital
 * Equivalent to , determines whether filenames implicitly start with a capital letter. The current implementation may give incorrect description page links when the local  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'.

 * useSplitMetadata
 * Store large chunks of FileMetadata in blob store. Some files have their entire text layer as metadata which can cause memory issues if stored directly on the file
