BulkTracker is a web application to track the status of bulk builds in NetBSD pkgsrc on various platforms. It is written in Go and runs on Google App Engine. The production instance is running at
https://bulktracker.appspot.com/
It uses the App Engine datastore, task queues and the URL Fetch service. The application is subscribed to the pkgsrc-bulk mailing list and receives build reports via email. It parses the email and tries to fetch the machine-readable report from the given URL. The report is split into records and saved in the datastore. The web UI allows examining aggregate and per-package results.
