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 *	type,
		const char *	module,
		const char *	name,
		const char *	data
	)

Apply default object wizard mappings.

Parameters

sorcery	Pointer to a sorcery structure
type	Type of object to apply to
module	The name of the module, typically AST_MODULE
name	Name of the wizard to use
data	Data to be passed to wizard

Returns

What occurred when applying the default

Note

This should be called after applying configuration sourced mappings

Only a single default can exist per object type

apply	Optional object set apply callback

Note

In general, this function should not be used directly. One of the various macro'd versions should be used instead.

__ast_sorcery_object_type_insert_wizard()

		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.

Since

13.26.0

16.3.0

Parameters

sorcery	Pointer to a sorcery structure
object_type_name	Name of the object type to remove from
module	The name of the module, typically AST_MODULE
wizard_type_name	The name of the of the wizard type to remove
wizard_args	Opaque string originally passed to the wizard

Note

If there were multiple instances of the same wizard type added to this object type without using wizard_args, then only the first wizard matching wizard_type will be removed.

ast_sorcery_lockable_alloc()

void * ast_sorcery_lockable_alloc	(	size_t	size,
		ao2_destructor_fn	destructor,

	)

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_reload_object()

void ast_sorcery_reload_object	(	const struct ast_sorcery *	sorcery,

Parameters

sorcery	Pointer to a sorcery structure
type	Name of the object type to reload

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 = 0

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.
