This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
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.
3829. [func] "dig +ttlunits" causes dig to print TTL values
with time-unit suffixes: w, d, h, m, s for
weeks, days, hours, minutes, and seconds. (Thanks
to Tony Finch.) [RT #35823]
3746. [func] New "max-zone-ttl" option enforces maximum
TTLs for zones. If loading a zone containing a
higher TTL, the load fails. DDNS updates with
higher TTLs are accepted but the TTL is truncated.
(Note: Currently supported for master zones only;
inline-signing slaves will be added.) [RT #38405]
the port, timeout, and retry options were
valid integers and in range. [RT #2099]
1150. [bug] named incorrectly accepted TTL values
containing plus or minus signs, such as
1d+1h-1s.
1149. [func] New function isc_parse_uint32().
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.
The macro DE_CONST is used to deal with a handful of very special
places where something is qualified as const but really needs to have
its const qualifier removed.
rdata.c now defines macros for the prototypes of the basic rdata functions,
and all of the lib/dns/rdata/**/*.c files now use them.
Some minor integer-compatibility issues. (IE, ~0x03 is a signed int,
so assigning it to an unsigned int should use a cast. The type of an
enum member is int, so there are some conversion issues there, too.)
A pointers-to-function should not be cast to a pointer-to-object.
Variables should not be named for C reserved identifiers.
One or two set-but-not-used variables removed.
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.
*/
Added:
isc_buffer_base(b) (pointer)
isc_buffer_current(b) (pointer)
isc_buffer_active(b) (pointer)
isc_buffer_used(b) (pointer)
isc_buffer_length(b) (int)
isc_buffer_usedlength(b) (int)
isc_buffer_consumedlength(b) (int)
isc_buffer_remaininglength(b) (int)
isc_buffer_activelength(b) (int)
isc_buffer_availablelength(b) (int)
Removed:
ISC_BUFFER_USEDCOUNT(b)
ISC_BUFFER_AVAILABLECOUNT(b)
isc_buffer_type(b)
Changed names:
isc_buffer_used(b, r) ->
isc_buffer_usedregion(b, r)
isc_buffer_available(b, r) ->
isc_buffer_available_region(b, r)
isc_buffer_consumed(b, r) ->
isc_buffer_consumedregion(b, r)
isc_buffer_active(b, r) ->
isc_buffer_activeregion(b, r)
isc_buffer_remaining(b, r) ->
isc_buffer_remainingregion(b, r)
Buffer types were removed, so the ISC_BUFFERTYPE_*
macros are no more, and the type argument to
isc_buffer_init and isc_buffer_allocate were removed.
isc_buffer_putstr is now void (instead of isc_result_t)
and requires that the caller ensure that there
is enough available buffer space for the string.
