This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
The current implementation only saves them as string. It seems they can be more complex than that, and that objects were saved directly. You may find such objects saved in some production databases by executing: ```sql SELECT * from oc_properties where propertyvalue = 'Object'; ``` This commit adds a repair job to clean all of these "broken" properties values, adds a new database column to save the type of the property, and handles converting from and to correct values. Implementation is very similar to SabreDAV's own PDO backend: https://github.com/nextcloud/3rdparty/blob/4921806dfb1c5c309eac60195ed34e2749baf3c1/sabre/dav/lib/DAV/PropertyStorage/Backend/PDO.php Signed-off-by: Thomas Citharel <tcit@tcit.fr>
