Shards database, collecting shard repositories, releases and dependencies.

• Crystal 0.30.1
• PostgresSQL database (for data storage). Should probably work with all versions => 10. Tested with PostgreSQL 11.5

PostgreSQL databases needs to be created manually. Connection configuration is read from environment variables:

• development database: DATABASE_URL
• testing database: TEST_DATABASE_URL (only for running tests)
• sentry: SENTRY_DSN (optional, for sending error reports to sentry)

Install database schema by running make db test_db.

Run shards install to install dependencies.

Run shards build worker to build the worker executable.

• bin/worker import_catalog: Reads repositories mentioned in catalog/*.yml files and synchronizes them with the database.
• bin/worker sync_repos [hours [ratio]]: Synchronizes data from git repositories to database for all repositories not synced in the last hours hours (default: 24) or never synced at all. ratio specifies the amount of outdated repositories being run in this job (default: 2.0 / hours). This enables an even distribution of batch sizes. Recommended to be run every hour.
• bin/worker updated_metrics: Updates shard metrics in the database. Should be run once per day.

A web application for browsing the database is available at https://github.com/shardbox/shardbox-web

Run make test to execute the spec suite.
