Hi all,
Just wondering if anyone knew of a good BSD license compatible key-based
hash placement / retrieval algorithm that was available anywhere.
I'm looking for a reliable way to lookup objects to see if a given action
would be performed in my revised pkg_install(1), to thus efficiently
pre-plan out the installation dependencies and fully utilize
multiprocessing capabilities of contemporary machines / eliminate duplicate
dependency install requirements.
I know I can use tree structures or hash(3), but I want to avoid trees
(inefficient with large data sets of course) and I was looking for a
non-BDB based solution (for right now, with this given structure as I don't
want to write everything to disk). Later on it might be a good idea to
cache the results using BDB on disk, but for now I was just wondering if
there were any non-BDB based hashing solutions that anyone knew of.

We imported hash(9) from Open/NetBSD recently. It may do what you want.
