1707
 * @defgroup authorize Authorized operations
1708
 * @{
1709
 * Functions to run operations with elevated privileges via authorize.php.
1710
 *
1711
 * Because of the Update manager functionality included in Drupal core, there
1712
 * is a mechanism for running operations with elevated file system privileges,
1713
 * the top-level authorize.php script. This script runs at a reduced Drupal
1714
 * bootstrap level so that it is not reliant on the entire site being
1715
 * functional. The operations use a FileTransfer class to manipulate code
1716
 * installed on the system as the user that owns the files, not the user that
1717
 * the httpd is running as.
1718
 *
1719
 * The first setup is to define a callback function that should be authorized
1720
 * to run with the elevated privileges. This callback should take a
1721
 * FileTransfer as its first argument, although you can define an array of
1722
 * other arguments it should be invoked with. The callback should be placed in
1723
 * a separate .inc file that will be included by authorize.php.
1724
 *
1725
 * To run the operation, certain data must be saved into the SESSION, and then
1726
 * the flow of control should be redirected to the authorize.php script. There
1727
 * are two ways to do this, either to call system_authorized_run() directly,
1728
 * or to call system_authorized_init() and then redirect to authorize.php,
1729
 * using the URL from system_authorized_get_url(). Redirecting yourself is
1730
 * necessary when your authorized operation is being triggered by a form
1731
 * submit handler, since calling drupal_goto() in a submit handler is a bad
1732
 * idea, and you should instead set $form_state['redirect'].
1733
 *
1734
 * Once the SESSION is setup for the operation and the user is redirected to
1735
 * authorize.php, they will be prompted for their connection credentials (core
1736
 * provides FTP and SSH by default, although other connection classes can be
1737
 * added via contributed modules). With valid credentials, authorize.php will
1738
 * instantiate the appropriate FileTransfer object, and then invoke the
1739
 * desired operation passing in that object. The authorize.php script can act
1740
 * as a Batch API processing page, if the operation requires a batch.
1741

 * To use authorize.php, certain variables must be stashed into $_SESSION. This
1751
 * function sets up all the necessary $_SESSION variables. The calling function
1752
 * should then redirect to authorize.php, using the full path returned by
1753
 * system_authorized_get_url(). That initiates the workflow that will eventually
1754
 * lead to the callback being invoked. The callback will be invoked at a low
1755
 * bootstrap level, without all modules being invoked, so it needs to be careful
1756
 * not to assume any code exists. Example (system_authorized_run()):
1757
 * @code
1758
