1707 * @defgroup authorize Authorized operations
1709 * Functions to run operations with elevated privileges via authorize.php.
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.
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.
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'].
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.
1742 * @see authorize.php
1744 * @see hook_filetransfer_info()
1748 * Setup a given callback to run via authorize.php with elevated privileges.
1750 * To use authorize.php, certain variables must be stashed into $_SESSION. This
1751 * function sets up all the necessary $_SESSION variables. The calling function
1752 * should then redirect to authorize.php, using the full path returned by
1753 * system_authorized_get_url(). That initiates the workflow that will eventually
1754 * lead to the callback being invoked. The callback will be invoked at a low
1755 * bootstrap level, without all modules being invoked, so it needs to be careful
1756 * not to assume any code exists. Example (system_authorized_run()):
1758 * system_authorized_init($callback, $file, $arguments, $page_title);
1759 * drupal_goto(system_authorized_get_url());
1761 * Example (update_manager_install_form_submit()):
1763 * system_authorized_init('update_authorize_run_install',
1764 * drupal_get_path('module', 'update') . '/update.authorize.inc',
1765 * $arguments, t('Update manager'));
1766 * $form_state['redirect'] = system_authorized_get_url();
1770 * The name of the function to invoke once the user authorizes the operation.
1772 * The full path to the file where the callback function is implemented.
1774 * Optional array of arguments to pass into the callback when it is invoked.

1776 * object created by authorize.php when the user authorizes the operation.
