1) There is no need to store the 'timemodified' value of
the section when backing up a course module, they do
not refer to the same time.
2) When creating a new course section during restore use
the current time.
3) Added timemodified value to more places when updating
the 'course_sections' table.
Add field 'visibleoncoursepage' to the course_modules table
Add site-wide setting for turning on stealth mode availability
Add callback for "stealth" mode support in the course formats
Change display of modules/sections availability on the course page
Using standard subplugin support, this commit implements
the backup of logstore subplugins in general and the
standard logstore in particular. Notes:
- Uses a custom final element (base64_encode_final_element) to
support the storage of serialized 'other' information in logs.
- Organization: Instead of directly extending backup_subplugin,
every logstore extends backup_tool_log_logstore_subplugin just
in case any shared code is needed in the future.
- Implements both course and activity logs, sharing the structure
completely (both are based in contextid to pick the target
information, from database or whatever other logstores use).
In order to implement the backup and restore of log stores, that
are created as subplugins of the tool_log plugin , we need to
extend subplugins support from activities to virtually any plugin.
Basically that implies moving the add_subplugin_structure() method from
its current, restricted, activity level to general backup_structure_step.
This commit implements the change in backup, covered with tests verifying
old, bc behavior and also new, general one.
In order to prevent changes in the existing grades when we fix bugs
we are introducing the gradebook code versioning. Each course may
"freeze" the code version to the older date. Freezing is usually done
during upgrade or restore and can be removed by the teacher by pressing
the button and accepting potential grade changes. There is no visible
setting and not possible to change the version back manually.
See MDL-50432 and MDL-50522
This setting is not compatible with combinations of aggregation methods
and the ways in which it does and does not work are not documented. It
was voted to remove it completely by the gradebook workshop, so I have
completely removed it and added a warning for all affected courses + restored
backups.
Implements backup and restore for the new conditional availability
data. This includes:
* Backup and restore of new field.
* Restore updates IDs in conditions, as required.
* Restore converts availability data from legacy (Moodle 2.6) backups.
* Unit tests for all this.
Files bigger than 4GB is not supported at this point. Zip archiver doesn't know about it and always returns true. We need to verify if it is a valid file or not and delete if not
Also delete the backup file immediately if anything goes wrong anywhere in backup. We don't want to use up space
Deleting directories at the end of backup can take a long time if
there are many directories (potentially up to 65536 file
directories). This change reports progress while deleting
directories to avoid timeout.
