What's here?

In development

A C++ version of sashimono agent

Libraries

• Crypto - Libsodium https://github.com/jedisct1/libsodium
• jsoncons (for JSON and BSON) - https://github.com/danielaparker/jsoncons
• Boost Stacktrace - https://www.boost.org
• Reader Writer Queue - https://github.com/cameron314/readerwriterqueue
• Concurrent Queue - https://github.com/cameron314/concurrentqueue

Setting up Sashimono Agent environment

• Place a hotpocket contract named default_contract (Copies of this contract will be made when new instances are created) inside the dependencies directory. This should be a new contract (Created by hpcore new). In the future this will be placed by the installation process.

• Run the setup script located at the repo root (tested on Ubuntu 18.04).

./dev-setup.sh

Build Sashimono Agent

1. Run cmake . (You only have to do this once)
2. Run make (Sashimono agent binary will be created as ./build/sagent)

Sashimono installation script.

1. Run sashimono-install.sh script as root user to setup sashimono environment.
2. Run sashimono-uninstall.sh script as root user to do sashimono cleanups.

Sashimono Client

• Replace the sashimono-client.key file created inside dataDir in the first run by the key file found on this link. This is because we have hardcoded the pubkey in message board. This will generate the same pubkey we have hardcoded.
• A sample bundle.zip bundle can be found here.

Code structure

Code is divided into subsystems via namespaces.

comm:: Handles generic web sockets communication functionality. Mainly acts as a wrapper for hpws.

conf:: Handles configuration. Loads and holds the central configuration object. Used by most of the subsystems.

crypto:: Handles cryptographic activities. Wraps libsodium and offers convenience functions.

hp:: Contains hotpocket instance management related helper functions.

hpfs:: Contains hpfs instance management related helper functions.

msg:: Extract message data from received raw messages.

salog:: Handles logging. Creates and prints the logs according to the configured log section in the json config.

sqlite:: Contains sqlite database management related helper functions.

util:: Contains shared data structures/helper functions used by multiple subsystems.
