RE: Build IDs for finding packages

[Bruce Dawson <bruced at valvesoftware dot com>]

That looks like it is just what I'm looking for -- but it failed on the first build ID I tried it on. I'm running a recent Fedora build (3.6.10-4.fc18.i686) on a VM with libc-2.16.so version 2.16 (compiled with gcc version 4.7.2 20121109). The Build ID for libc-2.16.so is cf7bdd994de74c7d4a0cff6a0293d96b64681e06, but when I navigate to this URL:

https://darkserver.fedoraproject.org/buildids/cf7bdd994de74c7d4a0cff6a0293d96b64681e06

I get a page that just contains [].

In this particular case I found the .rpm file at http://mirror.chpc.utah.edu/pub/fedora/linux/updates/18/i386/glibc-2.16-28.fc18.i686.rpm, but I'm curious as to why darkserver does not seem to be working in this case.

For Fedora there is Darkserver https://darkserver.fedoraproject.org/
Which has an simple API:

* Call to find server version
  https://darkserver.fedoraproject.org/serverversion

 This will return a dictionary like {'server-version':'0.1'}

* Call to get GNU build-id details
  https://darkserver.fedoraproject.org/buildids/0d0669e4ce89ffb335e36d41eacf3dfd04072e17

  This will return a dictionary of build-id details of 0d0669e4ce89ffb335e36d41eacf3dfd04072e17

* Call to get GNU build-id details of an RPM
  https://darkserver.fedoraproject.org/rpm2buildids/argyllcms-1.3.6-1.fc16.i686

  This will return a dictionary of build-id details of the rpm argyllcms-1.3.6-1.fc16.i686

* Call to get download url of a RPM
  https://darkserver.fedoraproject.org/package/argyllcms-debuginfo-1.3.6-1.fc16.i686

  This will return a download URL of the rpm in a dictionary.

Cheers,
