Manual:module_deps table

The module_deps table was for caching which local files a skin/module depends on that aren't registered directly.

No longer used for tracking images and LESS files that CSS depends on.

Module name

Skin name

JSON blob with file dependencies.

Since MediaWiki 1.25 (phabricator:T37472), update.php now deletes the contents of the module_deps table, thus clearing the cache. For versions of MediaWiki which do not yet have this fix in update.php, the workaround is to manually delete the contents of the module_deps table.
