Check that zone->view is not NULL before checking that zone->view->adb is not
NULL. It appears that zone maintenance can occur when the zone is shutting
down and the view pointer is NULL. We don't want to do zone maintenance in
this case.
If we're asking for a key and need to call dns_view_findzonecut(), set
the DNS_DB_NOEXACT flag. This means that the resolver will start look for the
key at or above the parent zone, and will return the key set from the parent
zone if key sets are present in both the parent and child.
307. [bug] When canceling a query, the resolver didn't check for
isc_socket_sendto() calls that did not yet have their
completion events posted, so it could (rarely) end up
destroying the query context and then want to use
it again when the send event posted, triggering an
assertion as it tried to cancel an already-canceled
query. (RT #77)
305. [bug] When reloading the server with a config file
containing a syntax error, it could catch an
assertion failure trying to perform zone
maintenance on tentatively created zones whose
views were never fully configured and lacked
an address database.
294. [bug] If we run out of space in while processing glue
when reading a master file and commit "current name"
reverts to "name_current" instead of staying as
"name_glue".
by dns_message_parse(), dns_message_findname() failed to find anything due
to checking for attribute bits set only by dns_message_parse(). This caused
an infinite loop when constructing the response to an ANY query at a CNAME
in a secure zone.
