It was necessary to add function for msg pack result in sqlite3 VDBE API.
The patchset is very raw. There are problems with the old tests that need
to be solved. I do not know if a piece of code with keyword checking works.
Could you send in the reply letter test samples for "unordered" and "noskipscan"
keywords?

Add function like sqlite3_result_blob that sets subtype of out parameter as
SQL_SUBTYPE_MSGPACK. It allows to encode msg pack fields.
Needed for #3372

Encode statN stat fields as msgpack array instead of string.
Closes #3372

Travis status is entirely negative - it can’t be compiled.
Please, make sure that at least build is successfully finished
before sending patch.

Actually, it wasn’t. You still can use result_blob and
set subtype after its invocation. Now it doesn’t matter much.

Ok, could you at least explain or enumerate existing problems
(in our char, in ticket comments, wherever you want) and
possible solutions.

What kind of samples do you need? To check that it works
you need get plan of query (explain query plan …), manually
update statisctics in _sql_stat space, probably restart instance
to load to in-memory structs new statistics and make sure
that plan of query has changed. Ofc not all plans will change,
but only those which are related to skip-scan optimisation
(don’t remember what the second token is responsible for).

The same is here. At least, fix names of params according to our codestyle.

What is the offset param? Describe it in the comment.
A bit broken indentation; put bracer at the next line.

mp_decode_array returns number of elements in array.
It is like rude to throw away that information.

I don’t understand why you can’t do this:
if (offset != NULL)
offset = &z;

Again indentation is broken a bit. Please, make space and tabs
visible in your code redactor.

Okay, there is some mess. Lets move this part to decode_stat_array.
There you already decoded that array, know its length and so on.
Instead of using offset output parameter, simply add one bit mask or two
bool output params.

Ok, I see below some commented tests, so I guess they fail
with segfaults or assertions. Please, dig into the problem.

The problem wasn’t related to segfaults or assertions. I remade some SQL tests with ORDER BY to Lua style. But its still don’t work in SQL.

You can simply do this:
_sql_stat1 = box.space._sql_stat1
> +_sql_stat1:insert{'t4', 't4i1', {'nonsense'}}

Firstly, it would be better if each test-related thing would
be placed in scope of test function. So, lets move these
insertions to test:do_test func (you can check out examples
in sql-tap/lua-tables.test.lua for instance).
Secondly, simple insertion to _sql_stat spaces doesn’t trigger
update of statistics in in-memory structs. In other words, these
tests check nothing (and without your patch as well). To make
these tests work, you should force statistics loading with instance
reload. I am not sure if this possible in tap suite, so probably you
should move these tests to sql/ suite.

If you don’t need one of params, just skip it:
for _, v in pairs(t) do

In this particular test(s), you pass the same limit and order by
args. So I’d rather hardcode them to make function smaller and
simpler.

Again you break philosophy of tap suite:
wrap this analyze statement into one of

Firstly, ‘unordered’ token should be the only member
of array, it should be placed after original statistics.
Secondly, without instance reloading all these insertions
to stat space make no sense.

commit 6e6393d1aae25dd387db330eb80a412b51f549d6
Author: Roman Khabibov <roman.habibov@tarantool.org>
