Perhaps what tjfn.c __IS__ would help. The toy test proggies that litter rpm cvs are haphazardly maintained and entirely undocumented.
One of the fundamental design featlets/bugtures is the fact that the rpmdb does its own join operation, rather than committing to a database method. The featlet is that very few methods, basically open/close/get/put/del, are needed to change what is used by an rpmdb. The bugture is that too much of the rpmdb implementation stays mired withing rpm itself, making more sophisticated database queries essentially impossible. tjfn.c (Test Join File Name) is an ancient proof-of-concept to use the existing Berkeley DB join instead. The implementation has never been completed because everyone finds it more useful to do same old, same old, forever, rather than actually improving the implementation. hth Code been there sine like rpm-3.0.5 iirc, long time anyways. 73 de Jeff On Dec 25, 2008, at 5:24 PM, Per Øyvind Karlsen wrote:
