Various pieces of the tagging system will break if the tag name contains slashes or commas, so that should be checked for. MediaWiki core (as of Ic5d75432) contains a method for doing just that, so use it if possible. Also require that tag names be either: * Intended for reuse (canAddTagsAccompanyingChange) * Already in use * Creatable This prevents the use of software-defined tags (unless whitelisted) or tags that are blocked from creation (e.g. OAuth reserved tag prefixes) Add caching for tag lookup since it's used more often now. Bug: T92956 Bug: T27151 Depends-On: Ic5d754323cbfd2c2b54c4df1245767946ebb1821 Change-Id: Ibc3095879f276a5436362f471b885e64f338522e
