Exception: CMD::Timeout

Inherits:
ProcessFailed show all
Defined in:
lib/scout/cmd.rb

Overview

ScoutCoder: exception raised by CMD.cmd when a command exceeds its :timeout option. It subclasses ProcessFailed, so generic rescue clauses for ProcessFailed also catch it. In pipe mode the stream is aborted with this exception (ConcurrentStream#abort), so consumers observe it through ConcurrentStream#stream_raise_exception when reading or joining the returned stream.
