An all-powerful toolset for $PAC.

Sentinel is an autonomous agent for persisting, processing and automating $PAC governance objects and tasks.

Sentinel is implemented as a Python application that binds to a local version xx paccoind instance on each $PAC Vxy Masternode.

This guide covers installing Sentinel onto an existing 12.1 Masternode in Ubuntu 14.04 / 16.04.

Make sure Python version 2.7.x or above is installed:

python --version

Update system packages and ensure virtualenv is installed:

$ sudo apt-get update
$ sudo apt-get -y install python-virtualenv

Make sure the local Paccoin daemon running is at least version 12.1 (120100)

$ paccoin-cli getinfo | grep version

Clone the Sentinel repo and install Python dependencies.

$ git clone https://github.com/PACCommunity/sentinel.git && cd sentinel
$ virtualenv ./venv
$ ./venv/bin/pip install -r requirements.txt

Set up a crontab entry to call Sentinel every minute:

$ crontab -e

In the crontab editor, add the lines below, replacing '/home/YOURUSERNAME/sentinel' to the path where you cloned sentinel to:

* * * * * cd /home/YOURUSERNAME/sentinel && ./venv/bin/python bin/sentinel.py >/dev/null 2>&1

Test the config by runnings all tests from the sentinel folder you cloned into

$ ./venv/bin/py.test ./test

With all tests passing and crontab setup, Sentinel will stay in sync with paccoind and the installation is complete

An alternative (non-default) path to the paccoin.conf file can be specified in sentinel.conf:

paccoin_conf=/path/to/paccoin.conf

To view debug output, set the SENTINEL_DEBUG environment variable to anything non-zero, then run the script manually:

$ SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py

Please follow the XXXX

  To contribute a patch, the workflow is as follows:

  • Fork repository
  • Create topic branch
  • Commit patches

  In general commits should be atomic and diffs should be easy to read. For this reason do not mix any formatting fixes or code moves with actual code changes.

  Commit messages should be verbose by default, consisting of a short subject line (50 chars max), a blank line and detailed explanatory text as separate paragraph(s); unless the title alone is self-explanatory (like "Corrected typo in main.cpp") then a single title line is sufficient. Commit messages should be helpful to people reading your code in the future, so explain the reasoning for your decisions. Further explanation here.
