Our Makefile required >= 2.6.4 for some time already.
It's pretty straightforward, except for zonefile.lua.in -> zonefile.lua

prefill: fix ca_file to actually expect file and not a directory

See merge request !578

This was leftover from an old version which used directory with
certificates instead of bundle in single file.

The example didn't work and I don't immediately see how to quickly fix
it, so let's have another more complex example instead (fished from an
older forum post of mine).

I also tried making a clickable define in the docs,
like for cache.ns_tout(), but I failed.

Some nameservers are hopelessly broken (ns1-ord.salesforce.com),
and will return lame negative answers which will flag the nameserver
as bad, so it wouldn't be picked for valid queries.

This is an issue for things like disabling minimisation, which only works
for the original query and not for the CNAME target.

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 one was missing from the current bindings. The checkout layer
runs when the worker attempts to send a DNS query to given upstream
when the address is already determined. The layer can add EDNS options
or update outbound query, or block particular addresses / protocol.

Closes #332.

This was probably lost during the cache backend rewrite in 2.x

Wrapping the error code in a structure preserves both the numeric value
and the ability to convert it into textual format.

Previous implementation forgot to clear the compression table, which is
an internal structure to packet. So when a recycled packet was reused,
it compared owners of newly inserted records with dangling pointers left
in the compression table.

This is less of a problem in query processing,
as each packet uses a memory pool, so the pointed names were never deallocated,
but it would write out wrong compression pointers because the compression
table kept pointing into packet that was now cleared and reused for something else.

It is more of a problem with packets created without a memory pool,
as the compression table kept references to memory that was already freed.
