Update the size-xxx-member tags to point to another field in the struct
that should be used for the length in that field. Fix NSEC3/HIP and TSIG
to use to this and generate the correct pack/unpack functions for them.
Remove IPSECKEY from the lib and handle it as an unknown record - it is
such a horrible RR, needed kludges before - now just handle it as an
unknown RR.
All types now use generated pack and unpack functions. The blacklist is
removed.
Add function that dedups a list of RRs. Work on strings, which
adds garbage, but seems to be the least intrusive and takes the
last amount of memory.
Some fmt changes snook in as well.
This will allow RRSIG.Sign to use generic crypto.Signer implementations.
This is a interface breaking change, even if the required changes are most
likely just type asserions from crypto.PrivateKey to the underlying type or
crypto.Signer.
TXT records consist out of multiple 255 byte chunk. When parsing
a chunk that is too large, Go DNS would happily add it. This would
only fail when packing the message.
Change this to auto-chunking when reading the TXT records from file
into 255 byte sized chunks.
Remove trailing \n from t.Log and t.Error messages as it's unnecessary.
In some instances, combine multiple t.Error()s into one
To provide more consistency across the tests, rename e to err and use %v
as the format arg for errors.
Replace Logf and Errorf with Log and Error when it made sense. For
example t.Errorf("%v", err) to t.Error(err)
IPSECKEY is kinda strange because it has a type selector which tells
what type a later rdata field has. The type can be a domainname, address
or v6 address. You sort of wish Go would have a union type for this, but
alas.
Currently this is implemented as:
GatewayA net.IP `dns:"a"`
GatewayAAAA net.IP `dns:"aaaa"`
GatewayName string `dns:"domain-name"`
In the IPSECKEY. Only one of these is active at any one time. When
parsing/packing and unpacking the value of GatewayType is checked
to see what to do.
Parsing from strings is also implemented properly and tested. The Unpack
function still needs work.
Now PrivateKey is an interface exposing Sign() and String(). Common
implementations are wrappers for {rsa|dsa|ecdsa}.PrivateKey but
this allows for custom signers, and abstracts away the private-ops
code to a single place.
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.
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.
Added a bunch a long running test function to the list of skipped
tests when giving -short to go test. Tests are bascially *all*
DNSSEC key generation tests and 1 serving test.
PASS
ok github.com/miekg/dns 0.782s
Compared to 13+ s, so quite a bit faster.
Don't panic when encountering dynamic update RRs in zonefiles.
There are some other failure cases when parsing, those will be
fixed in subsequent commits.
Closes#110
When not using this, TXT strings get interpreted by Golang, making
TXT behave unexpected. QuoteToASCII has surpises too, see
TestTxtEqual(), but this, I hope, lesser of an issue.
According to RFC4034 the timestamp in RRSIG may also be an EPOCH.
Check for this when parsing. Knot DNS zone dumps contain timestamp
RRSIG, this makes those parseable by Go DNS.
