Hi Everyone,
I'm happy to announce the third and probably last release candidate for Knot DNS 1.3.0 is out there!
This release candidate is a bit special to us, featuring not only a slew of bugfixes but also introducing a new feature.
Quite a lot of you asked for a tool to estimate memory consumption for given zone, this is now a new action 'memstats'
available in knotc utility. The usage is quite similar to the 'checkzone' command, but it prints out estimated memory
consumption instead. You can also pick specific zones if you like.
Second quite substantial change is deprecation of 'knotc start'. The preferred method of startup is now using knotd directly,
optionally with -d flag for running in background. Also, knotd doesn't create PID files when running in foreground.
This is to play nice with managed init scripts and to be able to write out PID atomically.
On top of that, you can also alter default 'storage' and 'rundir', see ./configure --help for that.
The 'rundir' obsoletes 'pidfile' config option, as the PID file will always be placed in 'rundir'.
Third and last substantial change is that knotc now uses UNIX sockets by default and is also now a preferred mode of operation,
although IP sockets are still supported. We believe this is safer for now, as the control protocol is not encrypted.
It is also enabled by default, to disable control interface completely, add an empty control section to the configuration.
But of course, being a release candidate, we didn't forget to pack in a bugfixes. Namely processing of IXFR with a lot
of serial changes, processing of TSIG keyfile in knotc and a couple performance regressions related to zone transfers.
Big thanks for numerous hours of testing and witty feedback for this release goes to Anand Buddhdev, thank you!
