Manual:Filearchive table

The filearchive table stores information on all the media that has been deleted, similar to the archive table's job for deleted text revisions. These files are located in the storage for deleted files; in the local storage this most likely is the folder images/deleted/. This is the table that makes image undeletion possible. Prior to MediaWiki 1.11, this was disabled per default, and Manual:$wgSaveDeletedFiles had to be set to true to enable it. Since version 1.11, the behavior is controlled by $wgFileStore, and deleted files are per default stored in $wgUploadDirectory/deleted. See also: Oldimage table

fa_id
Unique row id.

fa_name
Original base filename; key to image.img_name, page.page_title, etc.

fa_archive_name
Filename of archived file, if an old revision, with prepended timestamp. E.g. 20090311210905!Constant_and_setup.png.

fa_storage_group
Which storage bin (directory tree or object store) the file data is stored in. Should be 'deleted' for files that have been deleted; any other bin is not yet in use.

fa_storage_key
SHA-1 of the file contents plus extension, used as a key for storage. eg 8f8a562add37052a1848ff7771a2c515db94baa9.jpg

fa_deleted_user
User who deleted the file, if this file is deleted

fa_deleted_timestamp
Time of deletion, if this file is deleted

fa_deleted_reason
Deletion comment, if this file is deleted

fa_size
File size in bytes. Duplicate of img_size.

fa_width
Image width, in pixels. Duplicate of img_width.

fa_height
Image height, in pixels. Duplicate of img_height.

fa_metadata
Serialized PHP array of the file's properties. Duplicate of img_metadata.

fa_bits
Bit-depth of GIF/PNG palette-based images (up to 16-bit). Non-palette images (JPEG/PNG/TIFF/SVG) are 0 or 8. All other files default to 0. Duplicate of img_bits.

fa_media_type
Possibilities are UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, and ARCHIVE. Duplicate of img_media_type.

fa_major_mime
Possibilities are unknown, application, audio, chemical, image, message, model, multipart, text, and video. Duplicate of img_major_mime.

fa_minor_mime
E.g. jpeg, gif, png, etc. Duplicate of img_minor_mime.

fa_description
Description field given during upload. It's not the description page (associated File: wiki page), but the "summary" provided by the user in case of reupload. Duplicate of img_description.

fa_user
User ID of who uploaded the file. Duplicate of img_user.

fa_user_text
User name of who uploaded the file. Duplicate of img_user.

fa_timestamp
Timestamp of when upload took place. Duplicate of img_timestamp.

fa_deleted
Visibility of deleted revisions, bitfield.

fa_sha1
sha1 hash of file content
