With isc_mem_get() and dns_name_dup() no longer being able to fail, some
functions can now only return ISC_R_SUCCESS. Change the return type to
void for the following function(s):
* name_duporclone()
Remove the dynamic registration of result codes. Convert isc_result_t
from unsigned + #defines into 32-bit enum type in grand unified
<isc/result.h> header. Keep the existing values of the result codes
even at the expense of the description and identifier tables being
unnecessary large.
Additionally, add couple of:
switch (result) {
[...]
default:
break;
}
statements where compiler now complains about missing enum values in the
switch statement.
The additional processing method has been expanded to take the
owner name of the record, as HTTPS and SVBC need it to process "."
in service form.
The additional section callback can now return the RRset that was
added. We use this when adding CNAMEs. Previously, the recursion
would stop if it detected that a record you added already exists. With
CNAMEs this rule doesn't work, as you ultimately care about the RRset
at the target of the CNAME and not the presence of the CNAME itself.
Returning the record allows the caller to restart with the target
name. As CNAMEs can form loops, loop protection was added.
As HTTPS and SVBC can produce infinite chains, we prevent this by
tracking recursion depth and stopping if we go too deep.
add matching macros to pass arguments from called methods
to generic methods. This will reduce the amount of work
required when extending methods.
Also cleanup unnecessary UNUSED declarations.
sockaddr.c:147:49: error: pointer targets in passing argument 2 of ‘isc__buffer_putmem’ differ in signedness

The isc_buffer_allocate() function now cannot fail with ISC_R_MEMORY.
This commit removes all the checks on the return code using the semantic
patch from previous commit, as isc_buffer_allocate() now returns void.
getquad() was implemented back in 2001 to warn about IPv4 addresses in
non-dotted-quad form being used. As change 4900 (GL #13) removed all
uses of inet_aton(), which allowed such forms, with inet_pton(), which
does not allow them, there is no point in keeping getquad() around as it
now only prints an extra warning when the parser comes across an IP
address in a form which is not acceptable anyway. Replace all uses of
getquad() with inet_pton(AF_INET, ...).
