Hello Mark, I've applied the listed patches from - http://www.your.org/dnscache/ -> https://github.com/pjps/ndjbdns/commit/ef1875907a0e3cf632f66c3add91f08543c74f3c -> https://github.com/pjps/ndjbdns/commit/847523271f3966cf4618c5689b905703c41dec1c Could you please have a look at these? (in case you spot any discrepancies) These are not released yet, I'm writing couple of manuals for pickdns and pickdns-data, and soon plan to make a new release. Thank you. (In reply to comment #1) > These are not released yet, I'm writing couple of manuals for pickdns and > pickdns-data, and soon plan to make a new release. I think pickdns is obsolete: http://marc.info/?l=djbdns&m=105658967803056&w=1 (In reply to comment #1) > Hello Mark, > > I've applied the listed patches from - http://www.your.org/dnscache/ > > -> > https://github.com/pjps/ndjbdns/commit/ > ef1875907a0e3cf632f66c3add91f08543c74f3c > -> > https://github.com/pjps/ndjbdns/commit/ > 847523271f3966cf4618c5689b905703c41dec1c > > Could you please have a look at these? (in case you spot any discrepancies) The SOA part looks good, but I think you want the revised version of Jeff King's query merging patch: http://marc.info/?l=djbdns&m=123859517723684&w=3 Sorry about not linking to that earlier. I didn't realize that the patches hadn't been updated at your.org. (In reply to comment #2) > I think pickdns is obsolete: > http://marc.info/?l=djbdns&m=105658967803056&w=1 Ah crazy, didn't know about it! do you know if these tools are used any more? rbldns rbldns-conf rbldns-data walldns walldns-conf Also, I'll look at the updated query merging patch. Thanks so much.

As far as I know, their functionality is not duplicated by any other program in the djbdns suite. Here's the deployment scenario for walldns: http://cr.yp.to/djbdns/wall.html As far as rbldns, it's for running your own IP based DNS whitelist or blacklist. I suspect though, that most folks have long ago migrated to rbldnsd: http://www.corpit.ru/mjt/rbldnsd.html > Also, I'll look at the updated query merging patch. > > Thanks so much. FYI, here's a large patch that has a fix for the query merging performance problem if you can extract it from the epoll and dnscurve noise: http://marc.info/?l=djbdns&m=128690937702267&w=2 It should be GPL: http://marc.info/?l=djbdns&m=128747714925759&w=2 I think it's using a red-black tree instead of a linear scan.

I see, thanks for confirming. > FYI, here's a large patch that has a fix for the query merging performance > problem if you can extract it from the epoll and dnscurve noise: > > http://marc.info/?l=djbdns&m=128690937702267&w=2 > > I think it's using a red-black tree instead of a linear scan. That's interesting. I think for this release I'll stick to earlier patches from Jeff. Thanks so much!
