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 ISC_MEM_DEBUGSIZE and ISC_MEM_DEBUGCTX did sanity checks on matching
size and memory context on the memory returned to the allocator. Those
will no longer needed when most of the allocator will be replaced with
jemalloc.

CID 320481: Null pointer dereferences (REVERSE_INULL)
Null-checking "input" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
261 if (input != NULL) {
262 isc_buffer_free(&input);
263 }

265 if (printmemstats) {
266 isc_mem_stats(mctx, stdout);
The dns_message_create() function cannot soft fail (as all memory
allocations either succeed or cause abort), so we change the function to
return void and cleanup the calls.
wire_test is not only used by the dnstap system test, but also in
fuzz testing. it doesn't need to be installed, but it's useful to have it
built when BIND is. this commit moves it back from bin/tests/system to
bin/tests, as a noinst_PROGRAM so that it's built by "make all" but
not installed.
The bin/tests/wire_test helper program is currently not included in any
Makefile.am file. Move its source code to bin/tests/system and build it
along other helper tools when dnstap support is requested as the
"dnstap" system test needs this tool in order to pass.
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.
4184. [bug] Fixed a possible memory leak in name compression
when rendering long messages. (Also, improved
wire_test for testing such messages.) [RT #40375]
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.
Several unused functions removed from dispatch_tcp_test.c (left over
from when it was copied from dispatch_test.c).
Minor other ISC style cleanups.
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
