This commit changes the wire protocol to split between command
announcement and command payload to allow proper typing of sent and
received msgpack messages.
CRL fetching has been implemented as second command after the existing
health check command.
This commit adds basic serial link and protocol support. None of the commands
from the docs/design.md document is implemented yet.
The following new packages have been added:
- seriallink containing the serial link handler including COBS decoding and
encoding
- protocol containing the protocol handler including msgpack unmarshalling
and marshaling
- health containing a rudimentary health check implementation
- messages containing command and response types and generated msgpack
marshaling code
A client simulation command has been added in cmd/clientsim.
README.md got instructions how to run the client simulator. The
docs/config.sample.yaml contains a new section for the serial connection
parameters.
