no, I've continued development in a separate Git branch of the RRDTool
repository. If you want, I can make that available somewhere. I've
posted my changes as one huge patch since Tobi wanted it that way. The
patch could be found at
<http://verplant.org/temp/rrdtool-trunk-rrd_update_with_cache.patch>. It
has automatically been deleted in the meantime, but I've just fished it
out of the backup. I hope the patch still applies to the current trunk -
if not, I need to pull in the SVN changes that were made since then. The
file will be deleted again in 31 days.

I merged all that stuff into the RRDTool code, because Tobi expressed
interest in having the functionality in the core program and because, in
fact, that is the most sensible thing to do. Tobi repeatedly delayed
applying the changes because he wanted to ``let 1.3 in trunk for a
while''. At one point I got really annoyed and told the list. Quite a
few people expressed interest in the code, but to this date nothing more

If you want to contribute further changes I'd love to include them in
the patch. If you have questions regarding the code, don't hesitate to

I've CC'ed the list, just in case..
