When at it, switch to generating the libzscanner bindings.

The _t isn't uint8_t* anymore but a structure with .len and .data.

To work on RRSIG TTLs, libknot >= 2.7.1 is needed.

Closes: #320

Remove stray kr_zonecut_find_nsname() which somehow appeared in
45e38b3d.

Previously the module was created on configuration time, so it wasn't
possible to inject custom endpoints to the default interface.

We don't need the end, but I prefer to get rid of the exception,
as we now require libknot > 2.6 anyway and it only implies adding
a few more binding lines.

Only get-set operations are added, added some tests.

Checking query flags instead of global context option allows setting
overrides on individual queries. The effect is the same as query flags
start by copying request flags which start by copying context options.

This is generally useful for parsing records from packet, as they
are broken into individual RRs that need reassembling.

This adds metatype wrappers for kr_cache_insert_rr and kr_cache_sync
for the cache metatype, and tests.

Marek Vavruša authored 7 years ago and Vladimír Čunát committed 6 years ago

This updates the metatype to wrap knot_rrset_add_rdata and knot_rrset_init_empty
in a nicer way, and adds automatic GC destructor and tests.

Fields after kr_nsrep got offset; fortunately only new fields were
added in there, unused from lua so far.

Decision function is separated out.

This is a followup on addition of trace callbacks in the resolver library,
to get rid of the Lua/C interfacing in daemon and unify it with the log tracing.
All modules can now install completion callback on the kr_request object that
will be called after the resolution is done.

this surfaces the struct kr_cache through context variable,
it doesn't implement any API or documented interface for it,
so I just added a tests for the struct presence and introspection

This is useful in many troubleshooting scenarios when you want debug logs
just for a single request. It's going to expand on TRACE flag functionality
in the next PRs, so that special requests can be invoked with various tracers attached.

Currently this is only available in the C modules that can set the callback,
it's not called anywhere in the library yet.

Check differences between real and monotonic time.
It clears cache when this diffrence changes since
last cache clear.

This module is enabled by default, but disabled in Deckard tests.

Also fixed improper promotion of `ffi` to global variable.

In particular, try to make the locally-served zones valid,
including SOA and NS in apex, empty non-terminal vs. NXDOMAIN, etc.
I might've missed something, but it should certainly be closer to ideal.

If CNAME chain occurs CNAME is placed before AAAA.

I see no sane way to set the flags from lua, so I made a C function.

The output is only better if built with libknot >= 2.4.0.
As a side-effect, add lua method knot_rrset_t::txt_dump;
it's a light wrapper around knot_rrset_txt_dump.

Re-tested rolling with a.moot-servers.net, to be sure.

These shouldn't make any problems:
- the verbose messages don't print any scope, and
- reputation cache doesn't consider scope.

I believe it was unused, so no risk was caused, but better remove it.
There's the complication that its signature has changed since libknot-2.4.0.
