Manual:Oldimage table

This table holds information about old revisions of files. It will be filled when one uploads a new version of an existing file to the wiki. These files are moved to the folder /image/archive. Information on deleted images however will not be stored in the oldimage table; on deletion information is moved to the filearchive instead.

See also: Filearchive table

oi_name
Name of the image (file and article, seems to be the same). Comparable to img_name.

oi_archive_name
Name of the image, prefixed by a timestamp of the time where it became an old revision

oi_size
File size in bytes. Comparable to img_size.

oi_width
Image width, in pixels. Comparable to img_width.

oi_height
Image height, in pixels. Comparable to img_height.

oi_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. img_bits.

oi_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. Comparable to img_description.

oi_user
User ID of the user who uploaded the file. Comparable to img_user.

oi_user_text
Name of original uploader. Comparable to img_user_text.

oi_timestamp
Timestamp of original file upload. Comparable to img_timestamp.

oi_metadata
Serialized PHP array of the file's properties. Comparable to img_metadata.

oi_media_type
Possibilities are UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, and ARCHIVE. Comparable to img_media_type.

oi_major_mime
Possibilities are unknown, application, audio, chemical, image, message, model, multipart, text, and video. Comparable to img_major_mime.

oi_minor_mime
E.g. jpeg, gif, png, etc. Comparable to img_minor_mime.

oi_deleted
revdeleted

oi_sha1
The SHA-1 hash of the file contents in base 36 format. includes/GlobalFunctions.php's wfBaseConvert is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters. Comparable to img_sha1.
