In the last few days we managed to get Darkserver live in production. Thanks to Nirik and Dgilmore, without their help it was not possible.
This service is providing the API(s) based on which other developers can write tools to query details of build-ids. We Have build-id in every ELF we build from Fedora 8, but there was no good way to query them. More details on why we need the service can be found at the wiki page.
For now it is handling only primary architecture builds. Within last 4 days we have around 118k build-id(s) in the database.
