* Remove unused bytes.Buffer from dns/idn.encode.
This buffer is truncated and written to but never read from. It
serves no purpose and all tests pass with it removed.
It appears to have been introduced when puncycode.go was first
added in miekg/dns@e3c2c07.
* Produce less pointless garbage.
This change:
- removes several needless []byte -> string conversions,
- removes two needless append calls in HashName, and
- writes the hash to the same nsec3 []byte in HashName rather
than creating a new []byte on each of the k iterations.
These are all minor performance improvements that will likely
go entirely unnoticed. The changes will reduce the ammount of
garbage produced when calling CertificateToDANE, HashName,
(*SIG).Sign and TsigGenerate.
* Cleanup and removals
Gut rawmsg.go as most functions are not used. Reword some documentation.
Add more types to be checked for name compression.
* Yeah, we do use these
* Remove this function as well - only used one
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.
* Remove {un,}packUint{16,32}Msg functions.
unpackUint16Msg unpackUint32Msg packUint16Msg packUint32Msg implemented
functionality that is part of the encoding/binary package.
* Use encoding/binary's encoding in more places.
Remove the use of reflection when packing and unpacking, instead
generate all the pack and unpack functions using msg_generate.
This will generate zmsg.go which in turn calls the helper functions from
msg_helper.go.
This increases the speed by about ~30% while cutting back on memory
usage. Not all RRs are using it, but that will be rectified in upcoming
PR.
Most of the speed increase is in the header/question section parsing.
These functions *are* not generated, but straight forward enough. The
implementation can be found in msg.go.
The new code has been fuzzed by go-fuzz, which turned up some issues.
All files that started with 'z', and not autogenerated were renamed,
i.e. zscan.go is now scan.go.
Reflection is still used, in subsequent PRs it will be removed entirely.
These strings are domain names, so we should lowercase them before
using them.
Also add some tests for Tsig generation and verification.
(/ht ldns release).
This fixes bugs in MB and CNAME.copy() (using sprintName for copying),
IPSECKEY (missed copyIP) and OPT (partially, Options was not copied as
slice; EDNS0 objects themselves are still pointers).
This process probably fixes a bug in NSAPPTR.len(), after a similar one was
found in HINFO.len().
This should also make it easier to make changes to these functions, and
check their correctness.
Generate the code by running "go generate".
All the relevant functions now return an error instead of
a simple boolean. This greatly approves the feedback to coders.
Spotted some fishy error handling along the way and fix that too.
