Pairwise testing is a test case generation technique based on the
observation that most faults are caused by interactions of at most two

Process BIND configure options into a model that is subsequently
processed by the PICT tool in order to find an effective test vector.
That test vector is then used for configuring and building BIND using

Fix updating summary RPZ DB for mixed-case RPZs
Each dns_rpz_zone_t structure keeps a hash table of the names this RPZ
database contains. Here is what happens when an RPZ is updated:
- a new hash table is prepared for the new version of the RPZ by
iterating over it; each name found is added to the summary RPZ
database,
- every name added to the new hash table is searched for in the old
hash table; if found, it is removed from the old hash table,
- the old hash table is iterated over; all names found in it are
removed from the summary RPZ database (because at that point the old
hash table should only contain names which are not present in the
new version of the RPZ),
- the new hash table replaces the old hash table.
When the new version of the RPZ is iterated over, if a given name is
spelled using a different letter case than in the old version of the
RPZ, the new variant will hash to a different value than the old
variant, which means it will not be removed from the old hash table.
When the old hash table is subsequently iterated over to remove
seemingly deleted names, the old variant of the name will still be
there, causing the name to be deleted from the summary RPZ database
(which effectively causes a given rule to be ignored).
The issue can be triggered not just by altering the case of existing
names in an RPZ, but also by adding sibling names spelled with a
different letter case. This is because RBT code preserves case when
node splitting occurs. The end result is that when the RPZ is iterated
over, a given name may be using a different case than in the zone file
(or XFR contents).
Fix by downcasing all names found in the RPZ database before adding them
to the summary RPZ database.

No issues with the glue cache feature have been reported since its
introduction in BIND 9.12. As the rationale for introducing the
"glue-cache" option was to have a safety switch readily available in
case the glue cache turns out to cause problems, it is time to deprecate
the option. Glue cache will be permanently enabled in a future release,
at which point the "glue-cache" option will be made obsolete.

tracing of active sockets and handles
If NETMGR_TRACE is defined, we now maintain a list of active sockets
in the netmgr object and a list of active handles in each socket
object; by walking the list and printing `backtrace` in a debugger
we can see where they were created, to assist in in debugging of
reference counting errors.
On shutdown, if netmgr finds there are still active sockets after
waiting, isc__nm_dump_active() will be called to log the list of
active sockets and their underlying handles, along with some details
about them.

change from isc_nmhandle_ref/unref to isc_nmhandle attach/detach
Attaching and detaching handle pointers will make it easier to
determine where and why reference counting errors have occurred.
A handle needs to be referenced more than once when multiple
asynchronous operations are in flight, so callers must now maintain
multiple handle pointers for each pending operation. For example,
ns_client objects now contain:
- reqhandle: held while waiting for a request callback (query,
notify, update)
- sendhandle: held while waiting for a send callback
- fetchhandle: held while waiting for a recursive fetch to
complete
- updatehandle: held while waiting for an update-forwarding
task to complete
control channel connection objects now contain:
- readhandle: held while waiting for a read callback
- sendhandle: held while waiting for a send callback
- cmdhandle: held while an rndc command is running
httpd connections contain:
- readhandle: held while waiting for a read callback
- sendhandle: held while waiting for a send callback
