This includes the following changes:
3326. [func] Added task list statistics: task model, worker
threads, quantum, tasks running, tasks ready.
[RT #27678]
3325. [func] Report cache statistics: memory use, number of
nodes, number of hash buckets, hit and miss counts.
[RT #27056]
3324. [test] Add better tests for ADB stats [RT #27057]
3323. [func] Report the number of buckets the resolver is using.
[RT #27020]
3322. [func] Monitor the number of active TCP and UDP dispatches.
[RT #27055]
3321. [func] Monitor the number of recursive fetches and the
number of open sockets, and report these values in
the statistics channel. [RT #27054]
3320. [func] Added support for monitoring of recursing client
count. [RT #27009]
3319. [func] Added support for monitoring of ADB entry count and
hash size. [RT #27057]
Added API to create a set of UDP dispatches which can be shared
round-robin style when making upstream queries for authoritative
data; this should reduce lock contention in the query source
dispatch.
- multiple DLZ's can be specified, including multiple DLZ's using
the same driver; e.g., two different back-ends both loaded by the
dlopen driver
- new "search" option can be specified in a DLZ indicating whether
this DLZ database should be searched for unknown zones. The
default is "yes". If "no", then the zone can only be found by
named if it's registered in the zone table, which happens if the
zone is configured for dynamic updates, or if "dlz <dlzname>" is
specified in the zone statement. (The latter functionality is
incomplete in this commit).
support for addzone/delzone feature (see change
#2930). Removed "new-zone-file" option, replaced
with "allow-new-zones (yes|no)". The new-zone-file
for each view is now created automatically, with
a filename generated from a hash of the view name.
It is no longer necessary to "include" the
new-zone-file in named.conf; this happens
automatically. Zones that were not added via
"rndc addzone" can no longer be removed with
"rndc delzone". [RT #19447]
allow dynamic addition and deletion of zones.
To enable this feature, specify a "new-zone-file"
option at the view or options level in named.conf.
Zone configuration information for the new zones
will be written into that file. To make the new
zones persist after a restart, "include" the file
into named.conf in the appropriate view. (Note:
This feature is not yet documented, and its syntax
is expected to change.) [RT #19447]
maintenance. The new "managed-keys" statement can
be used in place of "trusted-keys" for zones which
support this protocol. (Note: this syntax is
expected to change prior to 9.7.0 final.) [RT #19248]
