The RemoveRRset method was the only one that had a check for RRsets.
While adding multiple identical RRs is an error, there should be now
check for that at this level.
Formatters are not needs you can access the members just fine.
However the rdata Field access function are handy and non-trivial,
extend them and add a basic test.
The dns package implements String() for all RR types, but sometimes you will
need more flexibility. The functions Printf, Sprintf, etc. implemented formatted I/O
for the RR type.
Printing
The verbs:
Generic part of RRs:
%N the owner name of the RR
%C the class: IN, CH, CLASS15, etc.
%D the TTL in seconds
%Y the type: MX, A, etc.
The rdata of each RR differs, we allow each field to be printed as a string.
Rdata:
%0 the first rdata field
%1 the second rdata field
%2 the third rdata field
.. ...
%9 the nineth rdata field
%R all rdata fields
The rdata fields remain a TODO, but will be implemented using
reflection.
Adds a field, NotifyStartedFunc func() to Server.
If non-nil, it is called after a server starts listening. This is useful
for synchronization purposes, for example when a daemon needs to drop
privileges after binding. Otherwise, there is no way to determine when
the server has begun listening and hardcoded delays (!) must be used or
race conditions may occur.
Added tests for the cmToM function to make sure that it's output is
correct. Modified the way the Altitude is written to a string. Previously,
if the altitude was an exact number of meters it would always be reported
with two decimal places. This is not needed. Conversely if it was not
an exact number of meters the cm were removed.
ECDSA public keys consist of a single value, called "Q" in FIPS
186-3. In DNSSEC keys, Q is a simple bit string that represents the
uncompressed form of a curve point, "x | y".
The ECDSA signature is the combination of two non-negative integers,
called "r" and "s" in FIPS 186-3. The two integers, each of which is
formatted as a simple octet string, are combined into a single longer
octet string for DNSSEC as the concatenation "r | s". (Conversion of
the integers to bit strings is described in Section C.2 of FIPS
186-3.) For P-256, each integer MUST be encoded as 32 octets; for
P-384, each integer MUST be encoded as 48 octets.
