Details[edit]

checkImages.php file is a maintenance script to check images to see if they exist, are readable, etc.

Technical details[edit]

These notes based on an examination of checkImages.php from MediaWiki version 1.19.

When executed, the main loop iterates through the wiki database's image table, fetching 1000 rows at a time by default, until all rows are obtained.

Each row specifies an image name, image size, and location of the associated image data.

If the location is filename on a local path, the filename is tested with stat().

unable to open file "$IMG missing"
file is directory "$IMG is a directory"
image size non-zero and file has zero length "$IMG truncated ..."
image size and file length not equal "$IMG size mismatch"

This test does not attempt to read any data from the image files, so it will not detect unreadable blocks in the local file system.

Options/Arguments[edit]

This script does not take any arguments.

Usage[edit]

php maintenance/checkImages.php
Terminal
$ php maintenance/checkImages.php

Good images: 27/27
