Allow both UI and automated backups to be created without
including files. Instead include only file references.
This is essentially implementing "SAMESITE" to backup files
instead of only for import and export functionality.
A new backup setting to include files (defaults to yes)
has been included.
The restore process will also look for and attempt to
restore files from the trashdir as part of restoring
backups. Additionally to support this process the
ammount of time files are kept in trashdir before they
are cleaned up via cron is also adjustable via admin
setting.
This patch adds sort ordering to the way courses are
automatically backed up. It sets the following preference:
Backup courses that do not have an entry in backup_courses first,
as they are likely new and never been backed up.
Backup courses that have the oldest next start time in backup_courses.
Give preference to most recently modified courses over other courses.
This patch replaces all homegrown timezone
stuff with standard PHP date/time code.
The main change is the introduction of core_date
class that returns normalised user and server
timezones. From now on nobody should be using
$CFG->timezone or $user->timezone directly!
Other new features and fixes:
* admins are prompted for timezone during install
* editing of other users is finally fixed
* timezones are displayed in user profile
* new $this->setTimezone() in phpunit
* time locale is now automatically reset in phpunit
* timezone is now automatically reset in phpunit
* phpunit has Australia/Perth as default timezone
Basically if the destination dir is empty then the storage
type should be set to the course backup area. This does
not affect the behaviour of the backups that lived with
misconfigured settings.
Set a correct backup status of ERROR when we fail to copy a file to an external directory given the backup configs demand it.
Also a lot of logs are added around this area to let admins easily find the problem if backup fails because of directory permissions.
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
