Convert \OCP\Files\StorageNotAvailableException to
\Sabre\DAV\Exception\ServiceUnavailable for every file/directory
operation happening inside of SabreDAV.
This is necessary to avoid having the exception bubble up to remote.php
which would return an exception page instead of an appropriate response.
- added file name check for the put, rename and setNames() methods which
throw a "Bad Request" whenever invalid characters are used
- replaced \OC\Filesystem usage with $this->getFS() to be able to write
unit tests
When mounting an ownCloud (backend OC) inside another ownCloud (frontend
OC), the frontend OC will use WebDAV to upload file, which will create
part files. These part files need to be accessible for the frontend OC
to rename them to the actual file name.
This fix leaves the file cache untouched but gives direct access to part
file info when requested.
This means that part file can be accessed only when their path and name
are known. These won't appear in file listtings.
Fixes#6068
