Overview

An FTP file system mapped to a disk directory. This can serve as a template for creating your own specialized driver.

Any method may raise a PermanentFileSystemError (e.g. “file not found”) or TransientFileSystemError (e.g. “file busy”). A PermanentFileSystemError will cause a “550” error response to be sent; a TransientFileSystemError will cause a “450” error response to be sent.

The class is divided into modules that may be included piecemeal. By including some mixins and not others, you can compose a disk file system driver “a la carte.” This is useful if you want an FTP server that, for example, allows reading but not writing files.
