Peter Rajnoha 245b85692e config: use config checks and add support for creating trees from config definition (config_def_create_tree fn) ... Configuration checking is initiated during config load/processing (_process_config fn) which is part of the command context creation/refresh. This patch also defines 5 types of trees that could be created from the configuration definition (config_settings.h), the cfg_def_tree_t: - CFG_DEF_TREE_CURRENT that denotes a tree of all the configuration nodes that are explicitly defined in lvm.conf/--config - CFG_DEF_TREE_MISSING that denotes a tree of all missing configuration nodes for which default valus are used since they're not explicitly used in lvm.conf/--config - CFG_DEF_TREE_DEFAULT that denotes a tree of all possible configuration nodes with default values assigned, no matter what the actual lvm.conf/--config is - CFG_DEF_TREE_NEW that denotes a tree of all new configuration nodes that appeared in given version - CFG_DEF_TREE_COMPLETE that denotes a tree of the whole configuration tree that is used in LVM2 (a combination of CFG_DEF_TREE_CURRENT + CFG_DEF_TREE_MISSING). This is not implemented yet, it will be added later... The function that creates the definition tree of given type: struct dm_config_tree *config_def_create_tree(struct config_def_tree_spec *spec); Where the "spec" specifies the tree type to be created: struct config_def_tree_spec { cfg_def_tree_t type; /* tree type */ uint16_t version; /* tree at this LVM2 version */ int ignoreadvanced; /* do not include advanced configs */ int ignoreunsupported; /* do not include unsupported configs */ }; This tree can be passed to already existing functions that write the tree on output (like we already do with cmd->cft). There is a new lvm.conf section called "config" with two new options: - config/checks which enables/disables checking (enabled by default) - config/abort_on_errors which enables/disables aborts on any type of mismatch found in the config (disabled by default)		2013-03-06 10:46:35 +01:00
