Use isc_time_secondsastimet() to set a time_t variable.
Properly skip the duplicate checking loop if the boundary time is not
successfully set (this was intended before, but coded wrongly).
Removed unused variable pid_string, after I opted to not add the
unrequested ISC_LOG_PRINTPID option half way into implementing it.
that the number of seconds in an isc_time_t does not
exceed the range of a time_t, or return ISC_R_RANGE.
Similarly, isc_time_now(), isc_time_nowplusinterval(),
isc_time_add() and isc_time_subtract() now check the
range for overflow/underflow. In the case of
isc_time_subtract, this changed a calling requirement
(ie, something that could generate an assertion)
into merely a condition that returns an error result.
isc_time_add() and isc_time_subtract() were void-
valued before but now return isc_result_t.
The seconds member isc_time_t on Unix platforms was changed from time_t
to unsigned int.
unix/time.c now uses macros for nanoseconds per second, nanoseconds per
microsecond and microseconds per second to make sure that the right
number of zeros appears each place the constant is used.
unix/time.c functions which take initialized isc_(interval|time)_t arguments
INSIST() that the nanoseconds value is less than one full second.
unix/time.c's isc_time_microdiff was broken because it did multiplication and
addition with unsigned integers and attempted to set them a 64 bit int to
avoid overflow, but C's ints don't promote to 64 bits on machines that only
have 32 bit longs. Fixed.
Added all the pertinent documentation to time.h.
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().
public functions did not have an isc__ prefix, and
referred to functions that had previously been
renamed.
184. [cleanup] Variables/functions which began with two leading
underscores were made to conform to the ANSI/ISO
function declaration and comment reformatting in accordance with coding
style document.

statements.
- Post-load of named.conf check verifies a slave zone has non-empty list
of masters defined.
- New per-zone boolean:
enable-zone yes | no ;
- intended to let a zone be disabled without having to comment out the
entire zone statement.
- New global and per-view option:
max-cache-ttl number
- New global and per-view option:
addition-data internal | minimal | maximal;
line 356: remark(1174): parameter "dev" was declared but never referenced
This is true when ISC_NET_BSD44MSGHDR is not defined. UNUSED()s were added.
line 1580: remark(1552): variable "task" was set but never used
line 1670: remark(1552): variable "task" was set but never used
I removed the stack variable and its assignment in each case.
line 2915: remark(1552): variable "ret" was set but never used
It was apparent that the variable was meant to be the return value
of isc_socket_getsockname, so the return statement was changed to use it.
Also ...
Changed function declarations to ISC coding style.
Wrapped two lines that were wider than column 79.
Removed two UNUSED() macros for variables that were no longer unused.
line 684: remark(1692): prototyped function redeclared without prototype
line 700: remark(1692): prototyped function redeclared without prototype
Prototypes fixed.
line 331: remark(1552): variable "n" was set but never used.
Variable removed.
It was removed and the function call that set it (getword) was cast to void.
In the context in which it was being used, the return value was not needed.
