bench-bot

This is a substrate-only bot at the moment.

How to use

The bot runs commands in response to pull request comments (example). The form is:

/bench [action] [...args]

Environment variables and Github settings have to properly configured upfront for this interaction to work.

Configuration

Create a .env file in the root with the following:

APP_ID=<App id from Github App Settings>
INSTALLATION_ID=<Installation id from Github Settings>
BASE_BRANCH=<the default branch for merging into the PRs, e.g. master>
CLIENT_ID=<Client ID from Github App Settings>
CLIENT_SECRET=<Client ID from Github App Settings>
PRIVATE_KEY_PATH=<Path the the private key of the github app>
WEBHOOK_SECRET=<Webhook secret from Github App Settings>
WEBHOOK_PROXY_URL=<optional; webhook proxy for development>

During development it's recommended to use smee for WEBHOOK_PROXY_URL because it enables testing your bot's functionality locally, without having to SSH into the dedicated machine.

Linting and formatting

The commands yarn run format and yarn run lint are available for ensuring style consistency on this project's code.

Running

Locally

yarn && yarn start

Dedicated machine

Note: Before disrupting the production deployment, it's first recommended to check if some benchmark is running through pgrep -a cargo .

The run script is used to manage the application. Use run help for documentation about its options.

run bootstrap will take care of creating and installing everything from scratch. For it to fully work, you'll also need to set up environment variables which optionally can be done through a .env file in the bot's directory.

Bot commands

• run {start,stop,restart}: execute the relevant action for the bot.
• run update [ref]: restart the bot with the branch or PR
  • For branch: ssh user@remote '/home/benchbot/bench-bot/run update master'
  • For PR: ssh user@remote '/home/benchbot/bench-bot/run update pull/number/head:branch' e.g. pull/1/head:master

Monitoring Service commands

• run monitor {install,uninstall}: install or uninstall the monitoring service
• run monitor {start,restart,stop,status,...}: acts as a wrapper for systemctl

Logs

The logs will be output to the systemd journal:

sudo journalctl -u benchbot-monitor.service

As well as to ./log.txt.
