All cache operations are now counted. These are internal cache
operations and do not map directly to number of queries or even number
of RRs.

Closes: !515

Function originally called kr_cache_sync() was in fact responsible
for calling mdb_txn_commit() and not mdb_env_sync() which was confusing.

and deduplicate the parsing logic.

It seems simpler, now that we have kr_rnd_buffered().

We use it as relatively high-level function, often on user-input names,
so it seems suitable that it does convert the case.
This fixes cache.clear('Example.Org.'), and probably also negative trust
anchors and policy uses.

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.

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.

Fixes https://gitlab.labs.nic.cz/knot/knot-resolver/issues/306

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.
