Overview

This module translates exceptions to FileSystemError exceptions.

A disk file system (such as Ftpd::DiskFileSystem) is expected to raise only FileSystemError exceptions, but many common operations result in other exceptions such as SystemCallError. This module aids a disk driver in translating exceptions to FileSystemError exceptions.

In your file system, driver, include this module:

module MyDiskDriver
  include Ftpd::TranslateExceptions

in your constructor, register the exceptions that should be translated:

def initialize
  translate_exception SystemCallError
end

And register methods for translation:

def read(ftp_path)
   ...
end
translate_exceptions :read
