move method of the MemoryFileSystem may accept invalid destination path
resulting in invalid entries in FS
----------------------------------------------------------------------------------------------------------
Key: JCR-1450
URL: https://issues.apache.org/jira/browse/JCR-1450
Project: Jackrabbit
Issue Type: Bug
Components: jackrabbit-core
Reporter: Denis Linine
Priority: Trivial
It seems there can be a problem with the move method of the MemoryFileSystem
class: when looking at its code it looks that it can accept destinations,
specifying folders that do not exist in the file system.
For example, if there is a "somefolder/somefile" file and I call the method
passing, say "somefolder/someotherfolder/somefile" as the destination. The
destination will be accepted by the code even if "somefolder/someotherfolder"
is not an existing folder and the function execution will result in a file
having the "somefolder/someotherfolder/somefile" path within a file system
having no "somefolder/someotherfolder" folder - the code should probably check
whether the destination path is really a valid one. Such validation could be
performed , for example, in the following way: take all path elements from the
destination path except the last one and insure that the resulting path points
to an existing folder, throw an exception otherwise.
Currently I have no JackRabbit build/test environment set up and could not
verify practically whether the issue described can really take place, the
supposition is made after looking at the move method implementation.
