Brian Carothers updated DNA-269:
--------------------------------

    Attachment: DNA-269.patch


Added patch that implements a writable file system connector.  The write capabilities have some limits.  Node ordering and same-name siblings are not supported.  Namespaces for paths (other than the default, empty namespace) are not permitted.  Primary types other than nt:folder, nt:file, dna:resource, and jcr:resource are not permitted.  Files with primary type jcr:resource are effectively converted to files of type dna:resource since references are not permitted and nt:resource has mix:referenceable as a supertype.

The concept of a maximum path length (FileSystemSource#maxPathLength) was added to limit the maximum length of the file path of any node that was created.  This came about after I wrote a deeply nested graph to my local filesystem and then found out that Windows won't let me delete extremely long paths.  I defaulted this value to 255 characters, but some research is needed to determine the correct length for Windows and other operating systems.

Because of all of the limitations (no arbitrary properties, no namespaces, no node ordering, no SNS), the canonical writable connector tests don't really pass, so I added a bespoke test suite for the writable capabilities of the connector.  I tried to make it as inclusive as I could, but other test cases are always welcome.

> The File System connector (DNA-34) currently only supports read-access to the files and folders.  Add update support, so a client can create files and folders (not other kinds of content) on the file system via the graph API and connector.
