Manual:Oldimage table

The oldimage 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  instead.

See also:

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

Comparable to .

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 .

oi_width
Image width, in pixels.

Comparable to .

oi_height
Image height, in pixels.

Comparable to .

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. .

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 .

<tvar|1>oi_description_id</> and the <tvar|2>comment</> table should be used instead!

oi_description_id
This is a foreign key to <tvar|1></> in the <tvar|2></> table.

oi_user
of the user who uploaded the file.

Comparable to <tvar|1></>.

While <tvar|1></> is being done, and depending on the configuration setting <tvar|2></>, this field may be empty and the actor performing the edit can be stored in the <tvar|3>oi_actor</> field instead.

oi_user_text
Name of original uploader.

Comparable to <tvar|1></>.

While <tvar|1></> is being done, and depending on the configuration setting <tvar|2></>, this field may be empty and the actor performing the edit can be stored in the <tvar|3>oi_actor</> field instead.

oi_timestamp
Timestamp of original file upload.

Comparable to <tvar|1></>.

oi_metadata
Serialized PHP array of the file's properties.

Comparable to <tvar|1></>.

oi_media_type
Possibilities are: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE

Comparable to <tvar|1></>.

oi_major_mime
Possibilities are: unknown, application, audio, chemical, image, message, model, multipart, text, video

Comparable to <tvar|1></>.

oi_minor_mime
E.g. jpeg, gif, png, etc.

Comparable to <tvar|1></>.

oi_deleted
revdeleted

oi_sha1
The SHA-1 hash of the file contents in base 36 format.

<tvar|1>includes/GlobalFunctions.php</>'s <tvar|2>wfBaseConvert</> is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters.

Comparable to <tvar|1></>.
