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.
The new recordset support for Postgres requires transactions and
will cause errors if recordsets are not closed correctly. This
commit fixes problems that were identified during unit tests, and
via some basic code analysis, across all core code. Most of these
are incorrect usage of recordset (forgetting to close them).
For historical reasons repositories need to call add_file_to_pool
to sync file records. However now that a before_file_created hook
has been added additional information is needed by add_file_to_pool.
Ideally add_file_to_pool and friends will become private/protected,
so we need to remove all uses of it in core.
This patch adds some new methods to the file class to allow syncing
to be managed internally by the file and the file_storage class.
This introduces a new "controlled link" file type where the file is not
stored in Moodle - but Moodle will control the access permissions on the file.
Plugins can "freeze" a filearea which means Moodle will take ownership of all the remote
files of this type.
When accessing a file, if the "filebrowser" infomation indicates the current user can write to the file, they
will be granted temporary write access.
Part of MDL-58220
This change moves all operations which deal with the fetching/updating, or
setting of files from the file_storage class into a new file_system class.
A new file_system can be specified in the config.php and used to replace
all relevant methods in order to move the file system component to an
alternative solution.
Fixes bug where the resource module loads metadata for all files while
building course modinfo, even though it only needs the first file.
(This causes problems if you have ~10k files.)
Changed the course libs such that module and section deletion is now
handed off to relevant functions in the util class and exempted
modules scheduled for deletion from the course backups.
This lets us convert between common office formats. E.g. docx -> pdf
html -> pdf, html -> ods.
This commit also updates assignment editpdf plugin to use this converter
on all compatible submission files.
