In Fedora 8 we had a feature of adding BuildID Support.

Darkserver is a service written to help people finding details of build-id(s). People will be able query the service based on build-id(s) or rpm package names. The service will provide output in JSON format as it will be easier for other tools to parse the output.

There is darkserver-import tool which can be used by a service like bodhi to run it against each package pushed through. It will populate a MySQL database with the details of build-id and ELF file details.

The current output format for a query of build-id   aa995549415cd52a6fbbc21811dfc2dd00e2c242

{"buildid":"aa995549415cd52a6fbbc21811dfc2dd00e2c242","elf":"/usr/lib/mailman/pythonlib/japanese/c/_japanese_codecs.so","rpm":"mailman-2.1.12-17.el6.x86_64.rpm"}

The Web service is written in Django. Package review is currently going on. Code base is in github.

There is a client called darkclient which will query the service and print the output in a way so that it will be easier for shell scripts to parse it.
