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)
