module_deps table

MediaWiki version:

≥ 1.17

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

Currently used for tracking images and LESS files that CSS depends on.

Fields

md_module

Module name

md_skin

Skin name

md_deps

JSON blob with file dependencies. Note: Contains absolute file paths, which are used to locate the according files. These paths will break when the wiki is e.g. moved to another folder or to another server (phabricator:T37472).

Until this bug is solved, you can use this workaround to manually fix wrong entries in the module_deps table:

SET @OLD='wiki.old-domain.org';
SET @NEW='wiki.new-domain.org';
 
UPDATE `module_deps` SET `md_deps` = REPLACE( `md_deps`, @OLD, @NEW );

This can be used to update wrong path segments and to fix the error.
