David Mudrák b7acd9be50 MDL-39023 Make get_language_dependencies() aware of circular dependency risk ... The patch reimplements the core_string_manager::get_language_dependencies() so that potentially mis-configured language packs with circular dependencies or self dependency do not make the site unavailable. Unit tests for the expected behaviour are added.		2013-04-08 14:31:27 +02:00
