OSS

A REST api for gcoin rpc.

Installation

Requirement

• Python 2.7
• virtualenv

Setup

./setup_venv.sh

Configuration

Set up setting.py

cp oss_server/oss_server/settings/setting.py.default oss_server/oss_server/settings/setting.py

Modify setting.py

Secret key

<SECRET_KEY>

This is used to provide cryptographic signing, and should be set to a unique, unpredictable value.

Environment

<ENV>

Fill in develop will enable oss_server/oss_server/settings/develop.py for debug information while running the project.

test: oss_server/oss_server/settings/test.py

It is designed for a standalone unit test process using a in-memory database.

production: oss_server/oss_server/settings/production.py

It disable debug information for production environment.

Allowed hosts

<ALLOW_DOMAIN>

Replacing it with * means it allowed requests from everywhere.

Use * for develop and subdomain format for production environment.

Gcoin rpc

Set up connection of gcoin rpc

GCOIN_RPC = {
    'user': '<GCOIN_RPC_USER>',
    'password': '<GCOIN_RPC_PASSWORD>',
    'host': '<GCOIN_RPC_HOST>',
    'port': '<GCOIN_RPC_PORT>',
}

Database

OSS uses mariadb to store blockchain data. Make sure to create a database named the same as <EXPLORER_DB_NAME>, then migrate with:

./manage.py migrate

DATABASES = {
    'default': {
        'NAME': '<EXPLORER_DB_NAME>',
        'ENGINE': 'django.db.backends.mysql',
        'HOST': '<EXPLORER_DB_HOST>',
        'PORT': '<EXPLORER_DB_PORT>',
        'USER': '<EXPLORER_DB_USER>',
        'PASSWORD': '<EXPLORER_DB_PSSWORD>',
        'CONN_MAX_AGE': 20
    }
}

Sync database with blockchain

<BLK_DIR>

The data forlder, which are usually located under ~/.gcoin/main/blocks

It is the key point for entire OSS project. The Django command called blockupdate will read all the blockchain data under this forlder every second by default and save these data to specified database.

Run ./manage.py blockupdate to sync blockchain indefinitely.

Run unit test

Run ./manage.py test --settings=oss_server.settings.test for a standalone unit test.

Run ./manage.py test will create a test database specified in setting.py and destroy it after compeleting the test.

Run server

Start server

./oss_server/manage.py runserver <address>:<port>

Start services

./manage.py blockupdate
./manage.py txnotify
./manage.py addressnotify
