The oslo_privsep.comm Module¶

Serialization/Deserialization for privsep.

The wire format is a stream of msgpack objects encoding primitive python datatypes. Msgpack ‘raw’ is assumed to be a valid utf8 string (msgpack 2.0 ‘bin’ type is used for bytes). Python lists are converted to tuples during serialization/deserialization.
