Yes it was actually me, who reimplement part of patchadd - dependancy check as pdo for Solaris10. Now it is not too much to speed up in patching - dependancy check if smallest fraction of patching and most time it spends in pkgadd.
I guess we may gain some performance this way but it will not really affect total patching time too much. Thanks, Roland it is really nice to know that even in script old patching has enormous potential to improve 20-60 times. I remember that when db was introduced, major conclusion and argument for that introduction was "there is no way to improve performance of current technology, but db gives us 50% improvement in any case". I know that we have great potential to improve in packaging also - no need to revolutionary changes like going to different software delivery model, but if we just program it right - it will be totally different story, like this happened to patch dependancy check in Solaris 10. Contents file + compression + moving functionality from scripts may speed up current solution in many times, without changing customer experience, delivering procedure etc. vassun This message posted from opensolaris.org
