Each mixin is assigned a specific exit status value to disambiguate the error type via exit status of user-facing utilities. The values start at 3 to provide distinction from common failure exit statuses (1 - something went wrong, 2 - argument error) that may be produced by user-facing utilities. In accord with mixin best practices these mixins are to be specified *before* an exception's superclass exception in the exception's definition. This allows for a subsystem base exception to provide a subsystem-wide exit status and for subsystem specific exceptions to specialize the exit status as appropriate. To avoid subclass proliferation simply to provide specific exit statuses one can chose to create a subsystem base exception using any of the ExitStatus hierachy classes (though, generally, one should probably only use ExitStatus itself) and provide a specific exit status for an exception at instantiation by passing any of the ExitStatus hierarchy classes as the 'exitStatus' instantiation parameter. $Id: //eng/vdo-releases/magnesium/src/python/vdo/vdomgmnt/ExitStatusMixins.py#1 $ """ class ExitStatus(object): """Base class for all ExistStatusMixins.
