This is a showcase prototype for the network structure of tractor.

• libzmq 4.2 or later
• Python 3.6+ (you need to install dataclasses on pypi for Python 3.6)
• Programs are tested under Python 3.9.0 and Fedora 33
• pyzmq 20.0.0 (you can use the requirements.txt to install though pip, pip install -r requirements.txt)

• server/: files for directory server
• storage/: files for storage "server"
• app/: files for a minial application to upload and download files

The directory server is the centre of the network, then you need to one or more storage server to store files (in this storage server implementation just allow one instance).

1. (optional) create a virtual environment and use. virtualenv venv && source venv/bin/activate
2. install python-side requirements. pip install -r requirements.txt
3. run directory server. python server/server.py
4. run storage server (maybe you need a new terminal window). python storage/storage.py

Then open a new terminal window to use app: cd app

• python app.py declare testdata1.txt: read testdata1.txt into a ramfs-like space and declare the app has it on directory server
• python app.py disown testdata1.txt: disown testdata1.txt on directory server
• python app.py show testdata1.txt: show the content of testdata1.txt on remote server

This prototype just a showcase for the powerful network design and it does not cover many keys in the complete design.
