| rewrite_step_backup_file_for_legacy_freeze($filepath) X-Ref |
| Rewrite step definition to handle the legacy freeze attribute. In previous backups the calculations_freeze property was stored as an attribute of the top level node <gradebook>. The backup API, however, do not process grandparent nodes. It only processes definitive children, and their parent attributes. We had: <gradebook calculations_freeze="20160511"> <grade_categories> <grade_category id="10"> <depth>1</depth> ... </grade_category> </grade_categories> ... </gradebook> And this method will convert it to: <gradebook > <attributes> <calculations_freeze>20160511</calculations_freeze> </attributes> <grade_categories> <grade_category id="10"> <depth>1</depth> ... </grade_category> </grade_categories> ... </gradebook> Note that we cannot just load the XML file in memory as it could potentially be huge. We can also completely ignore if the node <attributes> is already in the backup file as it never existed before. param: string $filepath The absolute path to the XML file. return: void |
Class: restore_grade_history_structure_step - X-Ref
Step in charge of restoring the grade history of a course.The execution conditions are itendical to {@link restore_gradebook_structure_step} because

NOTE: Not all course logs are being restored. For now only 'course' and 'user'
records are. There are others like 'calendar' and 'upload' that will be handled
later.

Class: restore_activity_grade_history_structure_step - X-Ref
Step in charge of restoring the grade history of an activity.This step is added to the task regardless of the setting 'grade_histories'.
The reason is to allow for a more flexible step in case the logic needs to be
split accross different settings to control the history of items and/or grades.
| execute_condition() X-Ref |
| This step is executed only if the grade history file is present. |

Class: restore_process_file_aliases_queue - X-Ref
Try to restore aliases and references to external files.The queue of these files was prepared for us in {@link restore_dbops::send_files_to_pool()}.
We expect that all regular (non-alias) files have already been restored. Make sure
there is no restore step executed after this one that would call send_files_to_pool() again.
You may notice we have hardcoded support for Server files, Legacy course files
and user Private files here at the moment. This could be eventually replaced with a set of
callbacks in the future if needed.
