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.
When a backup (or restore) is in progress and the user
has another tab open that is taking time to generate and
holding the session lock, a condition arises where
multiple ajax calls are "queued" because the long page
is holding the session lock. When this lock is released,
the queued ajax requests complete. However, as the ajax
requests also lock this can block other requests until they
complete. This patch decreases the frequency of ajax calls
and stops them from holding the session lock.
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.
Specially noticeable under Windows, where some resources/files
are kept open/busy/locked, causing all sort of problems, easily
detectable in phpunit resets.
The only different between each setting dependency type is the evaluation of the condition,
and the mform js validation arguments - so that should be the only thing that is extended
by each subclass.
With PHP 7.3, the hash (#) is being escaped by preg_quote().
While normally that doesnt have much impact and normal operations
continue working perfectly... when the results of the function are
used to match against the same string... they don't match anymore.
Have found a couple of there double-uses in core and this
commit fixes them. Covered with tests.
This patch adds asynchronous backup and restore functionality
to Moodle. This is an optional feature and is not enabled by
default. It can be enabled by site administrators.
Asynchronous backup and restores are actioned by the Moodle
adhoc task API. The progress of backup and restores is
displayedin the Moodle UI. Users can also be sent a message
when a backup or restore operation completes via the
Moodle messaging API.
When the course module cache is out of date during a gradebook re-calculcation it throws
throws exceptions because the module cannot be found. This prevents access to gradebook or
any type of grading functions until the cache is rebuilt.
When the cache still has no module record we log an error and return the course context.
This commit is part of work on Custom fields API,
to minimize commit history in moodle core the work of a team of developers was split
into several commits with different authors but the authorship of individual
lines of code may be different from the commit author.
