Defined in:
lib/nonnative/invalid_data_socket_pair.rb

Overview

Socket-pair variant used by the fault-injection proxy to simulate corrupted/incoherent traffic.

When active, data written to the upstream socket is corrupted by shuffling the characters in the payload before forwarding.

This behavior is enabled by calling FaultInjectionProxy#invalid_data.
