Transactions are the mechanism for changing property groups. They act atomically, whereby either all of the updates occur or none of them do. An scf_transaction_t is always in one of the following states:
The initial state. A successful return of scf_transaction_start() moves the transaction to the started state.
The transaction has started. The scf_transaction_property_delete(), scf_transaction_property_new(), scf_transaction_property_change(), and scf_transaction_property_change_type() functions can be used to set up changes to properties. The scf_transaction_reset() and scf_transaction_reset_all() functions return the transaction to the reset state.
A call to scf_transaction_commit() (whether or not it is successful) moves the transaction to the committed state. Modifying, resetting, or destroying the entries and values associated with a transaction will move it to the invalid state.
The scf_transaction_reset() and scf_transaction_reset_all() functions return the transaction to the reset state.
The scf_transaction_create() function allocates and initializes an scf_transaction_t bound to handle. The scf_transaction_destroy() function resets, destroys, and frees tran. If there are any entries associated with the transaction, scf_transaction_destroy() also effects a call to scf_transaction_reset(). The scf_transaction_destroy_children() function resets, destroys, and frees all entries and values associated the transaction.
The scf_transaction_handle() function gets the handle to which tran is bound.
The scf_transaction_start() function sets up the transaction to modify the property group to which pg is set. The time reference used by pg becomes the basis of the transaction. The transaction fails if the property group has been modified since the last update of pg at the time when scf_transaction_commit() is called.
The scf_transaction_property_delete(), scf_transaction_property_new(), scf_transaction_property_change(), and scf_transaction_property_change_type() functions add a new transaction entry to the transaction. Each property the transaction affects must have a unique scf_transaction_entry_t. Each scf_transaction_entry_t can be associated with only a single transaction at a time. These functions all fail if the transaction is not in the started state, prop_name is not a valid property name, or entry is already associated with a transaction. These functions affect commit and failure as follows:
This function deletes the property prop_name in the property group. It fails if prop_name does not name a property in the property group.
This function adds a new property prop_name to the property group with a value list of type type. It fails if prop_name names an existing property in the property group.
This function changes the value list for an existing property prop_name in the property group. It fails if prop_name does not name an existing property in the property group or names an existing property with a different type.
This function changes the value list and type for an existing property prop_name in the property group. It fails if prop_name does not name an existing property in the property group.
If the function call is successful, entry remains active in the transaction until scf_transaction_destroy(), scf_transaction_reset(), or scf_transaction_reset_all() is called. The scf_entry_add_value(3SCF) manual page provides information for setting up the value list for entries that are not associated with scf_transaction_property_delete(). Resetting or destroying an entry or value active in a transaction will move it into the invalid state.
The scf_transaction_commit() function attempts to commit tran.
The scf_transaction_reset() function returns the transaction to the reset state and releases all of the transaction entries that were added.
The scf_transaction_reset_all() function returns the transaction to the reset state, releases all of the transaction entries, and calls scf_value_reset(3SCF) on all values associated with the entries.
Upon successful completion, scf_transaction_create() returns a new scf_transaction_t. Otherwise, it returns NULL.
Upon successful completion, scf_transaction_handle() returns the handle associated with the transaction. Otherwise, it returns NULL.
Upon successful completion, scf_transaction_start(), scf_transaction_property_delete(), scf_transaction_property_new(), scf_transaction_property_change(), and scf_transaction_property_change_type() return 0. Otherwise, they return -1.
The scf_transaction_commit() function returns 1 upon successful commit, 0 if the property group set in scf_transaction_start() is not the most recent, and -1 on failure.
The scf_transaction_create() function will fail if:
The value of the handle argument is NULL.
There is not enough memory to allocate an scf_transaction_t.
The server does not have adequate resources for a new transaction handle.
The scf_transaction_handle() function will fail if:
The handle associated with tran has been destroyed.
The scf_transaction_start() function will fail if:
The repository backend refused the modification.
The repository backend refused modification because it is read-only.
The connection to the repository was lost.
The property group has been deleted.
The transaction and property group are not derived from the same handle.
The transaction is not in the reset state. The scf_transaction_reset() and scf_transaction_reset_all() functions can be used to return the transaction to the reset state.
The handle was never bound or has been unbound.
The property group specified by pg is not set.
The user does not have sufficient privileges to modify the property group.
The scf_transaction_property_delete(), scf_transaction_property_new(), scf_transaction_property_change(), and scf_transaction_property_change_type() functions will fail if:
The transaction has not been started.
The property group the transaction is changing has been deleted.
The property already has an entry in the transaction.
The prop_name argument is not a valid property name.
The transaction and entry are not derived from the same handle.
The handle is not bound.
The connection to the repository was lost.
The scf_transaction_property_delete(), scf_transaction_property_change(), and scf_transaction_property_change_type() functions will fail if:
The property group does not contain a property named prop_name.
The scf_transaction_property_new() , scf_transaction_property_change(), and scf_transaction_property_change_type() functions will fail if:
The prop_name argument is not not a valid property name, or the type argument is an invalid type.
The scf_transaction_property_new() function will fail if:
The property group already contains a property named prop_name.
The scf_transaction_property_change() function will fail if:
The property prop_name is not of type type.
The scf_transaction_commit() function will fail if:
The repository backend is read-only.
The repository backend refused the modification.
The handle is not bound.
The connection to the repository was lost.
The transaction is in an invalid state.
The property group the transaction is acting on has been deleted.
The transaction has not been started.
The user does not have sufficient privileges to modify the property group.
The server does not have sufficient resources to commit the transaction.
The scf_error(3SCF) function can be used to retrieve the error value.
Example 1 Set an existing boolean value to true.
tx = scf_transaction_create(handle); e1 = scf_entry_create(handle); v1 = scf_value_create(handle); do { if (scf_pg_update(pg) == -1) goto fail; if (scf_transaction_start(tx, pg) == -1) goto fail; /* set up transaction entries */ if (scf_transaction_property_change(tx, e1, "property", SCF_TYPE_BOOLEAN) == -1) { scf_transaction_reset(tx); goto fail; } scf_value_set_boolean(v1, B_TRUE); scf_entry_add_value(e1, v1); if (scf_transaction_add(tx, e1) == -1) { scf_transaction_reset(tx); goto fail; } result = scf_transaction_commit(tx); scf_transaction_reset(tx); } while (result == 0); if (result < 0) goto fail; /* success */ cleanup: scf_transaction_destroy(tx); scf_entry_destroy(e1); scf_value_destroy(v1);
