cast to dns_rdatatype_t via macros of their same name
so that they are of the proper integral type wherever
a dns_rdatatype_t is needed.
(And a few prototypes that I recently bogusly changed to take "int" parameters
in place of "dns_rdatatype_t" to accomodate the type of an enum identifier
have been reverted to again properly take a dns_rdatatype_t.)
Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const. Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.
Minor other ISC style cleanups.
database in an inconsistent state or fails when it shouldn't. This will be
supported at some point, but it's better to flat out refuse than fail badly.
- Eliminated massive code duplication
- Eliminated code for configuring forward and hint "zones",
as those no longer have zone objects. Left stub zones in
because those probably will have zone objects associated
with them.
- Fixed several bugs:
+ 'allow-transfer' was not obeyed for slave zones or stub zones
+ 'dialup' was not obeyed for stub zones
+ 'transfers-per-ns' was not obeyed for any zones
dns_dispatch_create() no longer exists. dns_dispatch_createtcp()
and dns_dispatch_getudp() are the replacements. _createtcp() takes
a bound, connected TCP socket, while _getudp() will search for
a sharable UDP socket, and if found, attach to it and return a
pointer to it. If one is not found, it will create a udp socket,
bind it to a supplied local address, and create a new dispatcher
around it.
dns_dispatch_remove{request,response}() no longer take the dispatch
as an argument.
query-source can now be set per view.
The dispatch manager holds onto three memory pools, one for
allocating dispatchers from, one for events, and one for
requests/replies. The free list on these pools is hard-coded,
but set to 1024. This keeps us from having to dig into the
isc_mem_t the pools draw from as often.
dns_resolver_create() and dns_view_createresolver() require that
valid dispatchers be passed in; dispatchers are no longer created
for the caller.
involved extensive restructuring of the reference counting of
zones and related objects.
Zones now attach to their views. To avoid a circular dependency that
would keep views from ever shutting down, this is done using the new
functions dns_view_weakattach() / dns_view_weakdetach() which
guarantee that the view will not be freed but still allow it
to be shut down.
The zones themselves now only have a single reference count, with
similar "weak" semantics. Managed zones must now be shut down
explicitly by calling dns_zone_shutdown(). To shut down all
zones in a zone table, call dns_zt_shutdown().
The zone manager is now reference counted, weakly. To shut down the
zone manager, you must explicitly call dns_zonemgr_shutdown().

allow-query ACL, subsequent accesses to the same zone were denied because
dbversion->queryok was not being set. This caused mandatory glue to be
omitted from referral responses, ultimately causing lookups to fail if all
authoritative servers for the parent zone were running bind9.
