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. Methods may also raise an FtpServerError with any desired error code.

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.
