        AST_SORCERY_WIZARD_POSITION_LAST, (wizard), (wizard_data))

Apply additional object wizard mappings returning wizard information.

Since

13.26.0

16.3.0

Parameters

	sorcery	Pointer to a sorcery structure
	object_type_name	Name of the object type to apply to
	wizard_type_name	Name of the wizard type to use
	wizard_args	Opaque string to be passed to the wizard May be NULL but see note below

Note

This should be called after applying default mappings

Although wizard_args is an optional parameter it is highly recommended to supply one. If you use the AST_SORCERY_WIZARD_APPLY_ALLOW_DUPLICATE flag, and you intend to ever remove a wizard mapping, you'll need wizard_args to remove specific instances.

ast_sorcery_objectset_create

#define ast_sorcery_objectset_create	(		sorcery,

	)		ast_sorcery_objectset_create2(sorcery, object, AST_HANDLER_PREFER_LIST)

Create an object set (KVP list) for an object.

Parameters

sorcery	Pointer to a sorcery structure
object	Pointer to a sorcery object

Return values

non-NULL	success
NULL	if error occurred

Note

The returned ast_variable list must be destroyed using ast_variables_destroy

This function attempts to use a field's sorcery_fields_handler first and if that doesn't exist or fails, a field's sorcery_field_handler is used. The difference is that the former may return multiple list entries for the same field and the latter will only return 1. It's up to the field itself to determine what the appropriate content is.

Register a boolean field as type OPT_YESNO_T within an object.

Simple Sorcery Convenience Macros

For simple scenarios, the following macros can be used to register common object fields. The only requirement is that your source code's definition of it's sorcery handle be named "sorcery".

Example structure:

struct my_sorcery_object {
  SORCERY_OBJECT(details);
  AST_DECLARE_STRING_FIELDS(
    AST_STRING_FIELD(mystring);
  );
 enum some_enum_type myenum;
 int myint;
 unsigned int myuint;
 int mybool;
};

Example object type registration:

ast_sorcery_object_register(sorcery, "myobject", ...);

Parameters

object	The unquoted object type.
structure	The unquoted name of the structure that contains the field without the "struct" prefix.
option	The unquoted name of the option as it appears in the config file.
field	The unquoted name of the field in the structure.
def_value	The quoted default value of the field. Should be "yes" or "no"

ast_sorcery_register_bool(myobject, my_sorcery_object, mybool, mybool, "yes");

Definition at line 1684 of file sorcery.h.

Register a custom field within an object.

Parameters

object	The unquoted object type.

Note

You must have defined the following standard sorcery custom handler functions:

• myobject_mystring_from_str(const struct aco_option *opt, struct ast_variable *var, void *obj)
• myobject_mystring_to_str(const void *obj, const intptr_t *args, char **buf)

Function Documentation

__ast_sorcery_apply_config()

enum ast_sorcery_apply_result __ast_sorcery_apply_config	(	struct ast_sorcery *	sorcery,
		const char *	name,
		const char *	module
	)

Apply configured wizard mappings.

Parameters

sorcery	Pointer to a sorcery structure
name	Name of the category to use within the configuration file, normally the module name
module	The module name (AST_MODULE)

This function is called automatically by __ast_sorcery_open() using the module name as the configuration category. The only reason you should call this function is if your module wishes to apply configuration from additional sections of sorcery.conf.

If a configuration section attempts to apply the same sorcery wizard to an object type more than once, the wizard will only be applied one time.

Returns

What happened when attempting to apply the config.

		const char *	wizard_args,
		enum ast_sorcery_wizard_apply_flags	flags,
		int	position,
		struct ast_sorcery_wizard **	wizard,
		void **	wizard_data
	)

Insert an additional object wizard mapping at a specific position in the wizard list returning wizard information.

Since

13.26.0

16.3.0

Parameters

	sorcery	Pointer to a sorcery structure
	object_type_name	Name of the object type to apply to
	module	The name of the module, typically AST_MODULE
	wizard_type_name	Name of the wizard type to use
	wizard_args	Opaque string to be passed to the wizard May be NULL but see note below
	flags	One or more of enum ast_sorcery_wizard_apply_flags
	position	An index to insert to or one of ast_sorcery_wizard_position
[out]	wizard	A variable to receive a pointer to the ast_sorcery_wizard structure. May be NULL if not needed.
[out]	wizard_data	A variable to receive a pointer to the wizard's internal data. May be NULL if not needed.

Returns

What occurred when applying the mapping

Note

This should be called after applying default mappings

Although wizard_args is an optional parameter it is highly recommended to supply one. If you use the AST_SORCERY_WIZARD_APPLY_ALLOW_DUPLICATE flag, and you intend to ever remove a wizard mapping, you'll need wizard_args to remove specific instances of a wizard type.

Determine if a sorcery object is stale with respect to its backing datastore.

Since

14.0.0

This function will query the wizard(s) backing the particular sorcery object to determine if the in-memory object is now stale. No action is taken to update the object. Callers of this function may use one of the ast_sorcery_retrieve functions to obtain a new instance of the object if desired.

Return values

0	the object is not stale
1	the object is stale

ast_sorcery_lockable_alloc()

void * ast_sorcery_lockable_alloc	(	size_t	size,
		ao2_destructor_fn	destructor,
		void *	lockobj
	)

Allocate a generic sorcery capable object with locking.

Since

14.1.0

Sorcery objects may be replaced with new allocations during reloads. If locking is required on sorcery objects it must be shared between the old object and the new one. lockobj can be any AO2 object with locking enabled, but in most cases named locks should be used to provide stable locking.

Parameters

size	Size of the object
destructor	Optional destructor function
lockobj	An AO2 object that will provide locking.

Return values

non-NULL	success
NULL	failure

ast_sorcery_retrieve_by_fields()

void * ast_sorcery_retrieve_by_fields	(	const struct ast_sorcery *	sorcery,
		const char *	type,
		unsigned int	flags,
		struct ast_variable *	fields
	)

Retrieve an object or multiple objects using specific fields.

Since

13.9.0

Parameters

sorcery	Pointer to a sorcery structure
type	Type of object to retrieve
flags	Flags to control behavior
fields	Optional object fields and values to match against

Return values

non-NULL	if found
NULL	if not found

Note

If the AST_RETRIEVE_FLAG_MULTIPLE flag is specified the returned value will be an ao2_container that must be unreferenced after use.

If the AST_RETRIEVE_FLAG_ALL flag is used you may omit fields to retrieve all objects of the given type.

The fields parameter can contain realtime-style expressions in variable->name. All operators defined for ast_strings_match can be used except for regex as there's no common support for regex in the realtime backends at this time. If multiple variables are in the fields list, all must match for an object to be returned. See ast_strings_match for more information.

Example:

The following code can be significantly faster when a realtime backend is in use because the expression "qualify_frequency > 0" is passed to the database to limit the number of rows returned.

struct ast_variable *var = ast_variable_new("qualify_frequency >", "0", ""); struct ao2_container *aors;

if (!var) { return; }

aors = ast_sorcery_retrieve_by_fields(ast_sip_get_sorcery(), "aor", AST_RETRIEVE_FLAG_MULTIPLE, var);

Variable Documentation

ast_sorcery_update_or_create_on_update_miss

int ast_sorcery_update_or_create_on_update_miss

extern

Global control for optional update->create fallback in backends.

When non-zero, writable Sorcery backends may attempt to call create() if update() indicates the object is missing (e.g., 0 rows affected or NOT_FOUND). This helps re-populate backends that temporarily missed an insert.

Default is 0 (off) to maintain legacy behavior.

Configured via sorcery.conf: [general] update_or_create_on_update_miss = yes|no

NOTE: Backends MUST gate their fallback logic on this variable.
