typedef uint32_t sr_edit_options_t

Options overriding default behavior of data manipulation calls, it is supposed to be bitwise OR-ed value of any sr_edit_flag_t flags.

Definition at line 353 of file sysrepo_types.h.

Enumeration Type Documentation

enum sr_edit_flag_t

Flags used to override default behavior of data manipulation calls.

Enumerator
SR_EDIT_DEFAULT	Default behavior - non-strict.
SR_EDIT_NON_RECURSIVE	Non-recursive behavior: by sr_set_item, all preceding nodes (parents) of the identified element must exist.
SR_EDIT_STRICT	Strict behavior: by sr_set_item the identified element must not exist (similar to NETCONF create operation), by sr_delete_item the identified element must exist (similar to NETCONF delete operation).
SR_EDIT_ISOLATE	Create new operation separately, independent of all the previous operations. Since all the operations are concatenated into one edit tree, it may happen that 2 incompatible operations are set and an error is observed. This flag can in those cases be used. Also, if an error is returned the previous edit is always left untouched.

Definition at line 336 of file sysrepo_types.h.

enum sr_move_position_t

Options for specifying move direction of sr_move_item call.

Enumerator
SR_MOVE_BEFORE	Move the specified item before the selected sibling.
SR_MOVE_AFTER	Move the specified item after the selected.
SR_MOVE_FIRST	Move the specified item to the position of the first child.
SR_MOVE_LAST	Move the specified item to the position of the last child.

Function Documentation

int sr_apply_changes	(	sr_session_ctx_t *	session,
		uint32_t	timeout_ms
	)

Apply changes made in the current session. In case the changes could not be applied successfully for any reason, they remain intact in the session.

Note: Note that in case that you are changing the running datastore, you also need to copy the config to startup to make the changes persistent.

Required WRITE access.

Parameters

[in]	session	Session (DS-specific) to apply changes of.
[in]	timeout_ms	Change callback timeout in milliseconds. If 0, default is used. Note that this timeout is measured separately for each callback meaning this whole function call can easily take more time than this timeout if there are changes applied for several subscribers.

Returns: Error code (SR_ERR_OK on success).

int sr_copy_config	(	sr_session_ctx_t *	session,
		const char *	module_name,
		sr_datastore_t	src_datastore,
		uint32_t	timeout_ms
	)

Replaces a conventional datastore with the contents of another conventional datastore. If the module is specified, limits the operation only to the specified module. If it is not specified, the operation is performed on all modules.

Note: Note that copying from candidate to running or vice versa causes the candidate datastore to revert to original behavior of mirroring running datastore (datastores).

Required WRITE access.

Parameters

[in]	session	Session (DS-specific - target datastore) to use.
[in]	module_name	Optional module name that limits the copy operation only to this module.
[in]	src_datastore	Source datastore.
[in]	timeout_ms	Configuration callback timeout in milliseconds. If 0, default is used.

Returns: Error code (SR_ERR_OK on success).

int sr_delete_item	(	sr_session_ctx_t *	session,
		const char *	path,
		const sr_edit_options_t	opts
	)

Prepare to delete the nodes matching the specified xpath. These changes are applied only after calling sr_apply_changes(). The accepted values are the same as for sr_set_item_str.

If SR_EDIT_STRICT flag is set the specified node must must exist in the datastore. If the path includes the list keys/leaf-list value, the specified instance is deleted. If the path of list/leaf-list does not include keys/value, all instances are deleted but there can be no further changes merged into the list, use SR_EDIT_ISOLATE in such a case.

For SR_DS_OPERATIONAL, the flag is not allowed. However, when trying to remove a value stored in the push operational data (set before using sr_set_item_str() on SR_DS_OPERATIONAL, for example), use sr_discard_items() instead.

Parameters

[in]	session	Session (DS-specific) to use.
[in]	path	Path identifier of the data element to be deleted.
[in]	opts	Options overriding default behavior of this call.

Returns: Error code (SR_ERR_OK on success, SR_ERR_OPERATION_FAILED if the whole edit was discarded).

int sr_discard_changes ( sr_session_ctx_t * session )

Discard prepared changes made in the current session.

Parameters

[in] session Session (DS-specific) to discard changes from.

Returns: Error code (SR_ERR_OK on success).

int sr_discard_items	(	sr_session_ctx_t *	session,
		const char *	xpath
	)

Prepare to discard nodes matching the specified xpath (or all if not set) previously set by the session connection. Usable only for SR_DS_OPERATIONAL datastore. These changes are applied only after calling sr_apply_changes().

Creates an opaque node discard-items in the sysrepo YANG module namespace with xpath used as the value. Such a node can be a part of the edit in sr_edit_batch() and will discard nodes like this function does.

Parameters

[in]	session	Session (DS-specific) to use.
[in]	xpath	XPath expression filtering the nodes to discard, all if NULL.

Returns: Error code (SR_ERR_OK on success).

int sr_edit_batch	(	sr_session_ctx_t *	session,
		const struct lyd_node *	edit,
		const char *	default_operation
	)

Provide a prepared edit data tree to be applied. These changes are applied only after calling sr_apply_changes().

Only operations merge, remove, and ether are allowed for SR_DS_OPERATIONAL.

Parameters

[in]	session	Session (DS-specific) to use.
[in]	edit	Edit content, similar semantics to NETCONF <edit-config> content. Uses `edit` and all of its following siblings.
[in]	default_operation	Default operation for nodes without operation on themselves or any parent. Possible values are `merge`, `replace`, or `none` (see NETCONF RFC).

Returns: Error code (SR_ERR_OK on success).

struct lyd_node* sr_get_changes ( sr_session_ctx_t * session )

Retrieve stored changes (prepared, not yet applied).

Note: as soon as the changes get applied or discarded, the return value becomes invalid.

Parameters

[in] session Session (DS-specific) to retrieve changes from.

Returns: The stored changes, or NULL, if there are none.

int sr_has_changes ( sr_session_ctx_t * session )

Learn whether there are any prepared non-applied changes in the session.

Parameters

[in] session Session (DS-specific) to check changes in.

Returns: non-zero if there are some changes, 0 if there are none.

int sr_move_item	(	sr_session_ctx_t *	session,
		const char *	path,
		const sr_move_position_t	position,
		const char *	list_keys,
		const char *	leaflist_value,
		const char *	origin,
		const sr_edit_options_t	opts
	)

Prepare to move/create the instance of an user-ordered list or leaf-list to the specified position. These changes are applied only after calling sr_apply_changes().

Item can be moved to the first or last position or positioned relatively to its sibling.

With default options it recursively creates all missing nodes (containers and lists including their key leaves) in the xpath to the specified node (can be turned off with SR_EDIT_NON_RECURSIVE option). If SR_EDIT_STRICT flag is set, the node must not exist (otherwise an error is returned).

For SR_DS_OPERATIONAL, neither option is allowed.

Note: To determine current order, you can issue a sr_get_items() call (without specifying keys of particular list).

Parameters

[in]	session	Session (DS-specific) to use
[in]	path	Path identifier of the data element to be moved.
[in]	position	Requested move direction.
[in]	list_keys	Predicate identifying the relative list instance (example input `[key1="val1"][key2="val2"]...`).
[in]	leaflist_value	Value of the relative leaf-list instance (example input `val1`) used to determine relative position, needed only if position argument is SR_MOVE_BEFORE or SR_MOVE_AFTER.
[in]	origin	Origin of the value, used only for SR_DS_OPERATIONAL edits. Module ietf-origin is assumed if no prefix used.
[in]	opts	Options overriding default behavior of this call.

Returns: Error code (SR_ERR_OK on success, SR_ERR_OPERATION_FAILED if the whole edit was discarded).

int sr_oper_delete_item_str	(	sr_session_ctx_t *	session,
		const char *	path,
		const char *	value,
		const sr_edit_options_t	opts
	)

Deprecated, use sr_delete_item().

int sr_replace_config	(	sr_session_ctx_t *	session,
		const char *	module_name,
		struct lyd_node *	src_config,
		uint32_t	timeout_ms
	)

Replace a datastore with the contents of a data tree. If the module is specified, limit the operation only to the specified module. If it is not specified, the operation is performed on all modules.

Required WRITE access.

Parameters

[in]	session	Session (DS-specific - target datastore) to use.
[in]	module_name	If specified, limits the replace operation only to this module.
[in]	src_config	Source data to replace the datastore in `session` connection libyang context. Is ALWAYS spent and cannot be further used by the application!
[in]	timeout_ms	Configuration callback timeout in milliseconds. If 0, default is used.

Returns: Error code (SR_ERR_OK on success).

int sr_set_item	(	sr_session_ctx_t *	session,
		const char *	path,
		const sr_val_t *	value,
		const sr_edit_options_t	opts
	)

Prepare to set (create) the value of a leaf, leaf-list, list, or presence container. These changes are applied only after calling sr_apply_changes(). Data are represented as sr_val_t structures.

With default options it recursively creates all missing nodes (containers and lists including their key leaves) in the xpath to the specified node (can be turned off with SR_EDIT_NON_RECURSIVE option). If SR_EDIT_STRICT flag is set, the node must not exist (otherwise an error is returned). Neither option is allowed for SR_DS_OPERATIONAL.

To create a list use path with key values included in predicates, value will be ignored. When creating key-less lists and state leaf-lists, use positional predicates such as [1] to refer to the instances. Using no predicate means the instance should be created.

The value of a leaf-list can be specified either by predicate in xpath or by value argument. If both are present, value argument is ignored and xpath predicate is used.

Edits preserve their order only if SR_EDIT_ISOLATE is used and in some cases it may affect the result.

Parameters

[in]	session	Session (DS-specific) to use.
[in]	path	Path identifier of the data element to be set.
[in]	value	Value to be set. `xpath` member of the sr_val_t structure can be NULL.
[in]	opts	Options overriding default behavior of this call.

Returns: Error code (SR_ERR_OK on success, SR_ERR_OPERATION_FAILED if the whole edit was discarded).

int sr_set_item_str	(	sr_session_ctx_t *	session,
		const char *	path,
		const char *	value,
		const char *	origin,
		const sr_edit_options_t	opts
	)

Prepare to set (create) the value of a leaf, leaf-list, list, or presence container. These changes are applied only after calling sr_apply_changes(). Data are represented as pairs of a path and string value.

Function provides the same functionality as sr_set_item().

Parameters

[in]	session	Session (DS-specific) to use.
[in]	path	Path identifier of the data element to be set.
[in]	value	String representation of the value to be set.
[in]	origin	Origin of the value, used only for SR_DS_OPERATIONAL edits. Module ietf-origin is assumed if no prefix used.
[in]	opts	Options overriding default behavior of this call.

Returns: Error code (SR_ERR_OK on success, SR_ERR_OPERATION_FAILED if the whole edit was discarded).

int sr_validate	(	sr_session_ctx_t *	session,
		const char *	module_name,
		uint32_t	timeout_ms
	)

Perform the validation a datastore and any changes made in the current session, but do not apply nor discard them.

Provides only YANG validation, apply-changes subscribers will not be notified in this case.

Parameters

[in]	session	Session (DS-specific) to use.
[in]	module_name	If specified, limits the validate operation only to this module and its dependencies.
[in]	timeout_ms	Operational callback timeout in milliseconds. If 0, default is used.

Returns: Error code (SR_ERR_OK on success).
